Background
Pneumoperitoneum needle is an important component of pneumoperitoneum machine in laparoscopic surgery, and is generally adopted when pneumoperitoneum is initially established, so the pneumoperitoneum needle plays an irreplaceable role.
The diameter of the needle core of the pneumoperitoneum needle is generally about 2mm, and the length is 80-150 mm. Since the maximum flow rate of the CO 2 gas flowing through the pneumoperitoneum needle core is affected by the diameter of the needle core, when the pneumoperitoneum is established by using the pneumoperitoneum needle, if the pneumoperitoneum needle is not identified and the desired gas supply flow rate of the pneumoperitoneum machine is limited after the pneumoperitoneum needle is identified, the flow rate flowing through the pneumoperitoneum needle core is liable to be excessively large. When the flow of the pneumoperitoneum needle core is too large, on one hand, CO 2 gas cannot smoothly pass through the pneumoperitoneum needle, on the other hand, the pressure in the pneumoperitoneum needle is too large, risks such as pneumoperitoneum needle ejection and air leakage occur, and the safety of equipment is further affected. Therefore, when the pneumoperitoneum is established by using the pneumoperitoneum needle, it is important to be able to automatically identify the connection state of the pneumoperitoneum needle, and after identifying the connection state of the pneumoperitoneum needle, it is also necessary to limit the desired air supply flow rate of the pneumoperitoneum machine.

Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to fall within the scope of the invention.
Example 1
As shown in fig. 1, a method for automatically identifying a pneumoperitoneum needle in a pneumoperitoneum machine includes:
S1, acquiring an air supply flow state of an air supply system of a pneumoperitoneum machine and dynamic pressure and measured flow at a pneumoperitoneum pipe in the pneumoperitoneum machine;
S2, judging whether the pneumoperitoneum machine enters a pneumoperitoneum needle mode according to the air supply flow state, the dynamic pressure and the actually measured flow;
And S3, when the pneumoperitoneum machine is judged to enter the pneumoperitoneum needle mode, setting the target expected air supply flow of the pneumoperitoneum machine.
The method comprises the steps of acquiring the air supply flow state of an air supply system of the pneumoperitoneum machine, and the dynamic pressure and the measured flow at the pneumoperitoneum pipe, and automatically identifying whether the pneumoperitoneum machine is in a pneumoperitoneum needle mode or not through comparison and judgment of the dynamic pressure and the measured flow at the air supply flow state, wherein the pneumoperitoneum machine is in the pneumoperitoneum needle mode, which represents that the pneumoperitoneum needle is in a connection state with the pneumoperitoneum pipe, or the pneumoperitoneum machine is not in the pneumoperitoneum needle mode, which represents that the pneumoperitoneum needle is not in the connection state with the pneumoperitoneum pipe, namely, automatically identifying whether the pneumoperitoneum needle is in the connection state with the pneumoperitoneum pipe, and in addition, when the pneumoperitoneum needle is in the pneumoperitoneum needle mode, automatically setting the target expected air supply flow of the pneumoperitoneum machine, which can prevent the flow from being excessively large when the pneumoperitoneum needle is connected with the pneumoperitoneum pipe, so that the occurrence of safety accidents is effectively avoided, manual intervention is not needed, and the method is convenient to use.
When it is determined in S2 that the pneumoperitoneum machine does not enter the pneumoperitoneum needle mode, the target expected air flow is not set, that is, the initial expected air flow is maintained unchanged.
In S1, the intra-pneumoperitoneum apparatus system may receive a start air supply signal flag and an air supply flow flag, for example, the "start air supply signal flag" is 1, which indicates that the pneumoperitoneum apparatus air supply system starts air supply, the "start air supply signal flag" is 0, which indicates that the pneumoperitoneum apparatus air supply system does not start air supply, and the "air supply flow flag" is 1, which indicates that the pneumoperitoneum apparatus air supply system has entered an air supply period (i.e., an air supply period has elapsed), and the "air supply flow flag" is 0, which indicates that the pneumoperitoneum apparatus air supply system has just started air supply. And acquiring the air supply flow state of the air supply system of the pneumoperitoneum machine through the received air supply starting signal mark and the air supply flow mark.
Preferably, in S1, acquiring the dynamic pressure and the measured flow rate includes:
s11, acquiring the dynamic pressure at the pneumoperitoneum tube in the pneumoperitoneum machine by using a pressure sensor;
s12, acquiring the actually measured flow at the pneumoperitoneum tube in the pneumoperitoneum machine by using a flow sensor.
In general, a pressure sensor and a flow sensor are arranged in the pneumoperitoneum machine, dynamic pressure is obtained through the pressure sensor, actual measurement flow is obtained through the flow sensor, and data acquisition which is convenient for judging a subsequent pneumoperitoneum needle mode can be realized only by utilizing the original hardware structure of the pneumoperitoneum machine without changing hardware or adding hardware independently.
Specifically, in this embodiment, the hardware structure of the pneumoperitoneum apparatus is shown in fig. 2, and the apparatus comprises a main control board 1 and an air channel 2, wherein the main control board 1 is arranged in a pneumoperitoneum apparatus body (not shown in the figure), the air channel 2 is arranged on the pneumoperitoneum apparatus body, a main control board main chip 11 adopts an STM32 singlechip, and further comprises a pressure sensor 12 and a flow sensor 13, and the air channel 2 comprises a pneumoperitoneum apparatus main machine air channel (not shown in the figure), and a pneumoperitoneum pipe joint 21, a pneumoperitoneum pipe 22, a luer joint 23 and a pneumoperitoneum needle 24 which are connected with the pneumoperitoneum apparatus main machine air channel. The pressure sensor 12 is disposed at a position close to the air passage of the pneumoperitoneum joint 21 for detecting real-time pressure (equal to the pressure in the abdomen of the patient) at the pneumoperitoneum joint 22, and the flow sensor 13 is also disposed at a position close to the air passage of the pneumoperitoneum joint 21 for detecting actual measurement flow at the pneumoperitoneum joint 22. The real-time pressure comprises static pressure and dynamic pressure, the real-time pressure detected by the pressure sensor is the static pressure and is equal to the intra-abdominal static pressure under the condition that the gas does not flow in the pipeline, the real-time pressure detected by the pressure sensor is the dynamic pressure under the condition that the gas flows, the dynamic pressure is related to the flow of the gas and an external gas path, the larger the flow is, the larger the dynamic pressure is, the smaller the inner diameter of the pipeline is, and the larger the dynamic pressure is. The diameter of the pneumoperitoneum needle core is far smaller than the inner diameter of the pneumoperitoneum Guan Luer joint, so that under the condition of the same flow rate, when the pneumoperitoneum needle is inserted to enable the pneumoperitoneum needle to be connected with a pneumoperitoneum pipe, the dynamic pressure detected by the pressure sensor can be obviously increased, when the pneumoperitoneum needle is pulled out to enable the pneumoperitoneum needle to be disconnected with the pneumoperitoneum pipe, the dynamic pressure detected by the pressure sensor can be reduced, and whether the pneumoperitoneum needle is in a connection state with the pneumoperitoneum pipe is judged according to the characteristic of the dynamic pressure.
Preferably, the air supply flow state includes an activated air supply state and an air supply period state;
S2 comprises the following steps:
S21, judging whether the pneumoperitoneum machine enters the pneumoperitoneum needle mode according to the dynamic pressure and the actually measured flow when the air supply system of the pneumoperitoneum machine is in the starting air supply state;
S22, judging whether the pneumoperitoneum machine is blocked according to the dynamic pressure when the air supply system of the pneumoperitoneum machine is in the air supply period state, and judging whether the pneumoperitoneum machine enters the pneumoperitoneum needle mode according to the dynamic pressure and the actually measured flow when the pneumoperitoneum machine is judged to be blocked.
Because the CO 2 gas flow in the pneumoperitoneum pipe is smaller when the gas supply is just started, when the pneumoperitoneum needle is in a connection state with the pneumoperitoneum pipe, the dynamic pressure detected by the pressure sensor is smaller, and is different from the situation that the dynamic pressure is caused when the pneumoperitoneum needle is suddenly connected with the pneumoperitoneum pipe in the gas supply process, whether the pneumoperitoneum machine enters a pneumoperitoneum needle mode or not is judged according to the situation, the connection state between the pneumoperitoneum needle and the pneumoperitoneum pipe can be more effectively and automatically identified, and the accuracy is higher.
Preferably, in S21 and S22, the determining whether the pneumoperitoneum machine enters the pneumoperitoneum needle mode according to the dynamic pressure and the measured flow includes:
presetting pneumoperitoneum needle identification flow and a first pressure threshold;
judging whether the dynamic pressure of the pneumoperitoneum machine under the pneumoperitoneum needle identification flow is larger than the first pressure threshold value or not;
If yes, judging that the pneumoperitoneum machine enters the pneumoperitoneum needle mode, and if not, judging that the pneumoperitoneum machine does not enter the pneumoperitoneum needle mode.
The method comprises the steps of identifying flow rate by a preset pneumoperitoneum needle as a flow rate standard for judging whether the pneumoperitoneum needle is in a connection state with a pneumoperitoneum tube in a starting air supply state, judging whether dynamic pressure exceeds a preset first pressure threshold value under the flow rate standard, effectively judging the connection state of the pneumoperitoneum needle with the pneumoperitoneum tube when an air supply system of a pneumoperitoneum machine is just started, and when the dynamic pressure exceeds the first pressure threshold value under the condition, indicating that the connection of the pneumoperitoneum needle with the pneumoperitoneum tube causes dynamic pressure change, judging that the pneumoperitoneum needle is in the connection state with the pneumoperitoneum tube, namely the pneumoperitoneum machine enters a pneumoperitoneum needle mode, otherwise, the pneumoperitoneum needle is not in the connection state with the pneumoperitoneum tube, namely the pneumoperitoneum machine does not enter the pneumoperitoneum needle mode.
Specifically, in this embodiment, the pneumoperitoneum needle identification flow rate and the first pressure threshold may be set and adjusted according to the actual situation, for example, the pneumoperitoneum needle identification flow rate is set to 2.5L/min.
Preferably, in S22, when the pneumoperitoneum machine air supply system is in the air supply period state, the determining whether the pneumoperitoneum machine is blocked according to the dynamic pressure includes:
presetting a second pressure threshold;
judging whether the dynamic pressure is greater than the second pressure threshold;
If yes, judging that the pneumoperitoneum machine is blocked, and sending out an alarm signal;
Otherwise, judging that the pneumoperitoneum machine is not blocked, and judging that the pneumoperitoneum machine does not enter the pneumoperitoneum needle mode.
When the pneumoperitoneum machine air supply system is in an air supply period state, namely when the pneumoperitoneum machine starts air supply and air supply is carried out for a period of time, at the moment, the pneumoperitoneum needle and the pneumoperitoneum pipe are switched from a non-connection state to a connection state in a very short time, so that larger dynamic pressure fluctuation can be caused, and blocking of the pneumoperitoneum machine can be caused, therefore, the connection state of the pneumoperitoneum needle and the pneumoperitoneum pipe can be judged by comparing the dynamic pressure with a preset second pressure threshold value, automatic identification of the pneumoperitoneum needle can be realized, and on the other hand, blocking of the pneumoperitoneum machine can be judged, and medical accidents can be effectively avoided by timely early warning through alarm signals.
Specifically, the second pressure threshold is greater than the first pressure threshold.
The second pressure threshold value and the first pressure threshold value are set and adjusted in advance according to actual conditions.
Preferably, S3 comprises:
presetting an initial expected air supply flow and a safe air supply flow of the pneumoperitoneum machine;
Setting the safe air supply flow rate to the target desired air supply flow rate when the initial desired air supply flow rate is greater than or equal to the safe air supply flow rate;
when the initial desired air supply flow rate is smaller than the safety air supply flow rate, the initial desired air supply flow rate is set as the target desired air supply flow rate.
When the pneumoperitoneum machine is judged to enter a pneumoperitoneum needle mode (namely, the pneumoperitoneum needle is in a connection state with the pneumoperitoneum pipe), the target expected air supply flow rate of the pneumoperitoneum machine can be limited in a smaller range when the pneumoperitoneum needle is in the connection state with the pneumoperitoneum pipe by comparing the preset initial expected air supply flow rate with the safe air supply flow rate and setting the minimum value of the initial expected air supply flow rate and the safe air supply flow rate as the target expected air supply flow rate according to the comparison result, and further, the automatic adjustment of the expected air supply flow rate when the pneumoperitoneum needle is in the connection state with the pneumoperitoneum pipe is realized, and the safety of the pneumoperitoneum machine is effectively ensured.
Specifically, in this embodiment, the initial desired air supply flow rate and the safety air supply flow rate are both set and adjusted in advance according to the actual situation, for example, the safety air supply flow rate is set to 3L/min, and the initial desired air supply flow rate is set to 10L/min in this embodiment.
Preferably, after S3, further comprising:
Judging whether the dynamic pressure is smaller than or equal to the first pressure threshold after the pneumoperitoneum machine enters the pneumoperitoneum needle mode;
If yes, judging that the pneumoperitoneum machine exits the pneumoperitoneum needle mode, and adjusting the target expected air supply flow rate of the pneumoperitoneum machine back to the initial expected air supply flow rate;
otherwise, determining that the pneumoperitoneum machine is kept in the pneumoperitoneum needle mode, and keeping the current expected air supply flow rate of the pneumoperitoneum machine in the pneumoperitoneum needle mode.
In the step S2, it can be determined that the pneumoperitoneum needle is in a connection state with the pneumoperitoneum tube in a state of starting the air supply and a state of the air supply period, and since there is a case that the pneumoperitoneum needle is in a connection state with the pneumoperitoneum tube and then is converted to an unconnected state in an actual air supply process, the embodiment can identify whether the pneumoperitoneum needle is pulled out of the pneumoperitoneum tube, namely, the pneumoperitoneum machine exits the pneumoperitoneum needle mode, and simultaneously when the pneumoperitoneum machine is identified to exit the pneumoperitoneum needle mode, the target expected air supply flow rate of the pneumoperitoneum machine is adjusted to the initial expected air supply flow rate so as to more conform to the actual working condition of the pneumoperitoneum machine, wherein when the dynamic pressure is greater than the first pressure threshold, the pneumoperitoneum machine is in the pneumoperitoneum needle mode, the pneumoperitoneum machine is identified, and the pneumoperitoneum needle is in the connection state is maintained, and the target expected air supply flow rate is kept unchanged. According to the embodiment, through the steps, the state of the pneumoperitoneum needle can be comprehensively and accurately automatically identified, the target expected air supply flow of the pneumoperitoneum machine is automatically adjusted, manual intervention is not needed, and medical accidents can be effectively avoided.
In the case where the initial desired air-sending flow rate is set to the target desired air-sending flow rate in the pneumoperitoneum needle mode, if it is determined that the pneumoperitoneum machine exits the pneumoperitoneum needle mode, the target desired air-sending flow rate at this time is the same as the initial desired air-sending flow rate, and the target desired air-sending flow rate is kept unchanged, and is substantially the same as the target desired air-sending flow rate of the pneumoperitoneum machine is adjusted back to the initial desired air-sending flow rate.
Specifically, the automatic identification complete flow of the pneumoperitoneum needle in the embodiment is as follows:
1. after the pneumoperitoneum machine is started, the system performs self-checking, and can normally feed air after the self-checking passes, and if the self-checking fails, a corresponding alarm signal, such as 'self-checking fails', is displayed.
2. After the self-checking is successful, the air supply is started, and the system detects the air supply flow state.
3. The system judges whether to enter a pneumoperitoneum needle mode, sets the safe air supply flow rate as a target expected air supply flow rate if the initial expected air supply flow rate is larger than the safe air supply flow rate once the pneumoperitoneum needle mode is detected, namely, limits the target expected air supply flow rate to be within the safe air supply flow rate, and sets the initial expected air supply flow rate as the target expected air supply flow rate if the initial expected air supply flow rate is smaller than the safe air supply flow rate, namely, limits the target expected air supply flow rate to be within the initial expected air supply flow rate.
4. During the pneumoperitoneum needle mode, the system detects whether the dynamic pressure is within a first pressure threshold, and once the dynamic pressure is detected within the first pressure threshold, the system automatically exits the pneumoperitoneum needle mode, and simultaneously cancels the limitation of the maximum flow rate, namely, the current expected air supply flow rate is adjusted back to the initial expected air supply flow rate (if the initial expected air supply flow rate is set as the target expected air supply flow rate in the pneumoperitoneum needle mode, the target expected air supply flow rate is kept unchanged).
