Description

  The present invention relates to a blood purification apparatus that includes a device main body for performing blood purification treatment on a patient, and in which display means for displaying the state of the patient or the device main body is provided in the device main body.

  A hemodialysis device for performing hemodialysis (HD) is a device that treats patients with impaired renal function and diffuses blood and dialysate through a semipermeable membrane such as a dialyzer. It is configured to remove excess water by removing solute by ultrafiltration and ultrafiltration. However, conventionally, many devices equipped with a touch panel monitor for displaying the state of the patient and the apparatus main body during dialysis treatment have been provided.

  Such a touch panel monitor can display the state of the patient or the apparatus main body and can input an operation or display related to hemodialysis treatment (blood purification treatment) to be arbitrarily operated. That is, the touch panel monitor has a screen that displays the state of the patient and the apparatus main body in real time, and constitutes display means that can be operated to perform a predetermined operation by touching a predetermined position on the screen.

  In addition, the touch panel monitor (display means) has been conventionally rotatable between a first position facing the operator side of a medical worker or the like and a second position facing the patient side. Accordingly, when a medical worker or the like performs an operation, the touch panel monitor is set to the first position, and when the display of the touch panel monitor is shown to the patient, the touch panel monitor can be rotated to the second position. . In addition, since this prior art does not relate to the literature known invention, there is no prior art document information to be described.

  However, since the display contents of the conventional blood purification apparatus do not change between when the touch panel monitor (display means) is at the first position and when it is at the second position, the touch panel monitor is moved to the second position. When rotating and showing the display to the patient, the contents that are not of interest to the patient or contents that are difficult to grasp are also displayed, and there is a problem that the visibility to the patient is poor. .

  That is, when the touch panel monitor is in the first position, various displays (displays contents that the operator needs to grasp) are made to the operator such as a medical worker, but when the display is in the second position as it is. Even if it is done, it will display a lot of information that is meaningless (not interested) for the patient, so it is necessary to search where the contents of interest to the patient are displayed, and visibility It will get worse.

  This invention is made | formed in view of such a situation, and is providing the blood purification apparatus which can improve the visibility at the time of directing a display means to a patient.

  The invention according to claim 1 is a blood purification apparatus comprising a device main body for performing blood purification treatment on a patient, and display means for displaying a state of the patient or the device main body disposed in the device main body. The display means is rotatable between a first position facing the operator side and a second position facing the patient side, and at the first position, displays for the operator, The display for the patient is performed at the second position.

  According to a second aspect of the present invention, in the blood purification apparatus according to the first aspect, the detection means for detecting the position of the display means, and the position detected by the detection means is either the first position or the second position. Recognizing means capable of recognizing whether the display means is a control means for causing the operator to display when the display means is in the first position and for the patient to be displayed when the display means is in the second position. It is characterized by comprising.

  According to a third aspect of the present invention, in the blood purification apparatus according to the first or second aspect, the display means has a screen for displaying the state of the patient and the apparatus main body and is input by touching a predetermined position on the screen. The touch panel is operable, and the input operation is restricted at the second position while the input operation is possible at the first position.

  According to the first and second aspects of the invention, the display means is rotatable between the first position facing the operator side and the second position facing the patient side, Since the display for the operator is performed at the time and the display for the patient is performed at the second position, the visibility when the display means is directed toward the patient can be improved.

  According to the invention of claim 3, the display means comprises a touch panel monitor having a screen for displaying the state of the patient and the apparatus main body and capable of performing an input operation by touching a predetermined position on the screen. Since the input operation is restricted at the second position while the operation is enabled, an inadvertent operation on the touch panel monitor by the patient can be avoided and erroneous input can be suppressed.

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
As shown in FIGS. 1 to 3, the blood purification apparatus according to the present embodiment includes an apparatus main body 1 that performs blood purification treatment on a patient, and display means 2 that displays the state of the patient or the apparatus main body. It is disposed in the apparatus main body 1.

  The apparatus body 1 is composed of a blood purification apparatus capable of performing treatment such as hemodialysis (HD), hemodiafiltration (HDF), hemofiltration (HF), or continuous slow blood filtration (CHF), for example, a blood pump. , A fluid replacement pump, a bubble detector, a syringe pump, a liquid crystal monitor, and the like, and a treatment unit 6 (see FIG. 3) that constitutes various devices for performing blood purification treatment on a patient. In this embodiment, the present invention is applied to a dialysis apparatus capable of performing hemodialysis treatment. However, instead of this, it is applied to an apparatus for performing other blood purification treatment (plasma exchange, double filtration plasma exchange, etc.). Also good. Moreover, in this embodiment, the apparatus main body 1 is comprised so that the dialysate can be supplied to the dialyzer connected to the blood circuit, and the drainage liquid from the dialyzer can be discharged.

  As shown in FIG. 4, the display unit 2 includes a screen 2 a that displays the state of the patient and the apparatus main body 1, and includes a touch panel monitor that can be operated by touching a predetermined position on the screen 2 a. Specifically, the patient's vital signs (biological information such as blood pressure) and the progress of water removal during treatment are displayed on the screen 2a, and any position indicated by reference numerals 2aa to 2ae on the screen 2a is displayed. By touching, an input according to the display is made.

  Further, at the bottom of the screen 2a, there are operation buttons 2b (blood pump operation button 2ba, alarm buzzer stop button 2bb, and power button 2bc) for performing power on / off operations and operations on the treatment unit 6 of the apparatus body 1. Is formed. The operation button 2b can also be used to input an operation or display related to blood purification treatment to any operation.

  The display means 2 has a first position facing the operator on the front side of the apparatus main body 1 (see FIG. 1) and a second position facing the patient lying on the bed B (see FIG. 2). It is possible to rotate between. That is, when an operator such as a medical worker performs an input to the display unit 2, the display unit 2 is set to the first position to improve the operability and to display the display of the display unit 2 to the patient. Is configured to rotate the display means 2 to the second position so that the display of the screen 2a can be visually recognized.

  On the other hand, as shown in FIG. 3, the apparatus main body 1 is provided with detection means 3, recognition means 4, and control means 5. The detection means 3 is for detecting the position of the display means 2, and for example, a micro switch, a reed switch, a photo sensor, a rotation angle sensor (rotational position sensor), or the like can be used. In the present embodiment, as shown in FIGS. 6 and 7, a microswitch 7 having a detection unit 7a is used.

  The microswitch 7 can be rotated in conjunction with the rotation of the display means 2. When the display means 2 is in the first position, as shown in FIG. 6, the microswitch 7 is electrically turned off. ing. Thus, when the display means 2 is rotated to the second position, as shown in FIG. 7, the detection portion 7a is electrically turned on by interfering with the convex portion 8 formed on the base portion H. Yes. As a result, when the display means 2 is in the first position and when it is in the second position, it is possible to electrically turn on and off to detect the position.

  The first position where the display unit 2 faces the operator side and the second position where the display unit 2 faces the patient side vary depending on the layout in which the apparatus body 1 is disposed, and thus the apparatus body 1 is installed. At this time, it is preferable that the first position and the second position can be set. For example, as shown in FIG. 8, a position between the position where the display unit 2 is rotated from the position facing the patient side to θ1 is defined as the first position, and a position between the position where the display means 2 is rotated to the position facing the patient side In the case of the second position, these θ1 and θ2 can be appropriately set.

  On the other hand, if a rotation angle sensor (which can continuously detect the rotation angle and output information such as a voltage according to the rotation angle and position) is used as the detection means 3, the rotation angle of the display means 2 can be electrically detected. Since it is possible to obtain the information (voltage etc.), it is possible to obtain the display for the operator and the display for the patient by changing the setting of the display conditions (voltage value as the threshold value) stored in the database D. The setting position can be changed by simply changing the software setting without adjusting the hardware.

  The recognizing means 4 is composed of computing means E electrically connected to the detecting means 3, and can recognize whether the position detected by the detecting means 3 is the first position or the second position. In this embodiment, the microswitch 7 is configured to be able to recognize whether the microswitch 7 is electrically on or off and recognize its position. The calculation means E of the recognition means 4 is configured to be able to exchange information with a predetermined database D. The database D stores various data that can recognize the first position and the second position, and data such as a display form on the display unit 2 at each position.

  The control means 5 is electrically connected to the recognition means 4 and the display means 2 and causes the recognition means 4 to display for the operator when the display means 2 is in the first position, and to the second position. At some point, the display for the patient is performed. That is, when the display means 2 is in the first position and faces the operator side, as shown in FIG. 4, the display for the operator is performed, while the display means 2 is turned to the second position and faces the patient side. When it is, the display for the patient is performed.

  Specifically, when the display means 2 is in the second position, as shown in FIG. 5, the remaining time and progress of dialysis treatment (blood purification treatment), integrated water removal amount, water removal amount setting, water removal speed, etc. The contents interested in the patient are displayed on the screen 2a of the display means 2. The contents of interest to the patient include vital signs (biological information) of the patient who is undergoing dialysis treatment (during blood purification treatment), and the vital sign is displayed in real time on the display means 2 at the second position. It can also be displayed. That is, the display for the operator when the display means 2 is in the first position means displaying the contents that can be grasped by the medical staff as in the conventional case, and for the patient when the display means 2 is in the second position. The display means displaying contents of interest to the patient or contents easy to grasp.

  Furthermore, in the present embodiment, when the display means 2 is in the first position and faces the operator, the blood purification is performed by touching the predetermined positions 2aa to 2ae on the screen 2a or operating the operation buttons 2b. While it is possible to input an operation or display related to treatment to be arbitrarily operated, when the display means 2 is in the second position and faces the patient, the input operation is not accepted. .

  Therefore, according to the present embodiment, the display means 2 can be rotated between the first position facing the operator side and the second position facing the patient side, and input is performed at the first position. Since the input operation is restricted at the second position while the operation is enabled, an inadvertent input to the display means 2 by the patient can be avoided and erroneous input can be suppressed. In this case, the database D may be configured to allow a highly urgent operation even when input is restricted.

  Further, in the present embodiment, when the display unit 2 is in the second position, only the contents of interest to the patient can be displayed and input (in the present embodiment, predetermined positions 2aa to 2ae on the screen 2a). Although it is configured not to perform itself, even in a state where it is in the second position, all or part of the display for input may be performed and the input may be prohibited. As described above, in the present embodiment, the display means 2 includes the screen 2a for displaying the state of the patient and the apparatus main body and includes a touch panel monitor that can be operated by touching a predetermined position on the screen 2a. 2 can be more easily regulated.

  According to the above embodiment, the display means 2 is rotatable between the first position facing the operator side and the second position facing the patient side, and the operator is at the first position. Since the display for the patient is performed and the display for the patient is performed at the second position, the visibility when the display means 2 is directed to the patient can be improved. The display unit 2 includes a screen 2a for displaying the state of the patient and the apparatus main body 1 and includes a touch panel monitor that allows an input operation by touching a predetermined position on the screen 2a. The input operation can be performed at the first position. Therefore, the input operation is restricted at the second position, so that an inadvertent operation on the touch panel monitor by the patient can be avoided and erroneous input can be suppressed.

  Further, if the settings of θ1 and θ2 in FIG. 8 can be finely adjusted, for example, the display for the patient cannot be displayed unless the screen 2a of the display means 2 is completely directed to the patient side. If 2a is returned, it can be set to display for the operator. Thereby, in an emergency, the display for the operator can be performed even if the staff does not completely return the screen 2a to the second position.

  In addition, when the display means 2 reaches the first position from the second position, a delay time is set so that the display for the operator is performed after a certain period of time rather than the display for the operator immediately. You may make it the structure which can do. In this case, the display for the operator can be performed based on the timepiece included in the computer and the detection state of the second position.

Next, the control contents in the present embodiment will be described based on the flowchart of FIG.
First, the position of the display means 2 (monitor position) is detected by the detection means 3 (S1), the monitor position is identified by the calculation means E of the recognition means 4, and the display means 2 is the first position facing the operator side. Or in a second position facing the patient (S2). Thereafter, it is determined whether or not there is a request to change the display form of the screen 2a (S3). If there is a request, a display for the patient is displayed on the screen 2a (S4). The display form in 2a is not changed (S5).

  Then, based on the position of the display means 2, it is determined whether or not there is an input operation restriction (input restriction) on the display means 2 (S6), and the display means 2 is in the second position by the control means 5. The operation on the display means 2 is restricted (S7), and when the display means 2 is in the first position, the operation on the display means 2 is allowed (input allowed) (S8).

  Although the present embodiment has been described above, the present invention is not limited to this. For example, when the display unit 2 is rotated from the first position to the second position, the patient is interested in the display on the screen 2a. Certain contents (the above-mentioned vital signs, the remaining time of treatment, etc.) may be displayed in large size, or may be displayed while being conspicuous in different colors and forms. In other words, the display by the display means 2 may be made significantly different between when it is in the first position and when it is in the second position, and in addition to this, the contents of interest to the patient are emphasized so as to be easily visible. There may be.

  In the present embodiment, the display means 2 is composed of a touch panel monitor, but may be different from the touch panel monitor (however, it displays the state of the patient or the apparatus main body). As other display means, for example, an LCD monitor having LEDs or the like arranged in parallel, a sheet key, a switch, or the like, or a voice input may be provided.

  The display means is rotatable between a first position facing the operator side and a second position facing the patient side, and at the first position, displays for the operator, As long as it is a blood purification device that displays a patient's display at the second position, it can also be applied to devices that have different external shapes or that have other functions added.
