Description

A Pulse Diagnosis Instrument with Pressure Limiting Protection Function

technical field

The invention relates to a pulse diagnosis instrument with the function of pressure limiting protection.

Background technique

At present, pulse diagnosis is a method of palpation by touching the pulse of different parts of the human body to observe changes in pulse conditions. Also known as cutting pulse, diagnosing pulse, pressing pulse, and holding pulse. The formation of the pulse condition is closely related to the qi and blood of the viscera. If the qi and blood of the viscera are diseased, the operation of the blood vessels will be affected, and the pulse condition will change. Pulse diagnosis can be used clinically to infer the progress and prognosis of a disease. The pulse diagnosis used in ancient Chinese medicine in diagnosing diseases is a unique diagnosis method, one of the "four diagnosis" (look, smell, ask, feel) in traditional Chinese medicine, and an indispensable objective basis for syndrome differentiation and treatment.

In recent years, due to the prevalence of Western medicine in China and traditional Chinese medicine’s excessive reliance on old Chinese doctors, Chinese medicine was once neglected or even rejected. With the efforts of Chinese medical and scientific research workers, it has also begun to gain Development and progress, especially after the combination of traditional Chinese medicine and modern diagnostic thinking, Chinese medicine has begun to make great progress in theory and diagnostic methods.

In clinical practice, when a doctor cuts the pulse of a patient, the pulsation of the pulse will stimulate the tactile corpuscle, which will convert energy from the tactile corpuscle, convert the physical stimulus into a nerve electrical signal, and transmit it to the nerve center brain through the sensory nerve to form a sense of touch, and then Combined with relevant medical knowledge to form various pulse conditions. In this process, since the formation of the sense of touch is a subjective feeling, there are many subjective contents in the description of the pulse condition. Therefore, traditional Chinese medicine pulse diagnosis is inseparable from the doctor's sensory perception, which results in the absence of an objective standard evaluation and definition of the disease, which greatly limits the promotion and recognition of traditional Chinese medicine pulse diagnosis.

The existing commercially available pulse diagnosis instrument adopts the rigid automatic pressurization design driven by the stepping motor, and the control signal is sent by the PC control system, and the stepping distance of the stepping motor can be precisely controlled through the driving circuit. Rigid connection is used between them, so as to realize the precise positioning of the probe during the pressurization process, and to a certain extent, an objective standard evaluation and definition of the disease can be made, but there is a certain risk of loss of control in the mechanical structure, although the safety limit can be set through the computer program, but it cannot be foolproof. The most dangerous and easy to lose control of the pulse diagnosis instrument is the rigid automatic pressure driven by the stepping motor. The probe directly contacts the human wrist. Due to the rigid transmission structure, once it loses control, it will cause great damage to the wrist.

Contents of the invention

In order to solve the above technical deficiencies, the present invention provides a pulse diagnostic instrument with pressure limiting protection function, which has reasonable design and good protection effect.

The present invention is achieved through the following measures:

A pulse diagnosis instrument with pressure limiting protection function of the present invention comprises a frame, on which

A crossbeam that can slide up and down is provided, a vein cutting groove is arranged on the frame below the crossbeam, a fixed base is arranged on the crossbeam, and a vertical slider is embedded in the outer surface of the fixed base, and the slider is matched with A linear guide rail that can slide up and down, and a probe is installed at the lower end of the linear guide rail;

The upper part of the fixed base is provided with a transverse pre-tightening through hole, the outer port thread of the pre-tightening through hole is threaded with an adjusting bolt, the inner port of the pre-tightening through hole is located at the inner bottom of the slider, and the inner port of the pre-tightening through hole is A pre-tightening ball is provided, and a compression spring is arranged in the pre-tightening through hole between the pre-tightening ball and the adjusting bolt, and a number of springs are arranged on the inner side of the linear guide rail, which can be connected with the pre-tightening through hole when the linear guide rail slides up and down. The port is opposite to the circular groove, and the diameter of the pre-tightening ball is larger than the diameter of the circular groove.

The cross-section of the fixed base is L-shaped, and the lower part of the fixed base is connected to the beam.

The beneficial effects of the present invention are: when the crossbeam moves down suddenly out of control, the linear guide rail can slide upwards, thereby avoiding sudden impact on the wrist and improving the reliability and safety of the pulse diagnosis instrument. Moreover, the pre-tightening pressure of the linear guide rail can be adjusted according to the needs, which is more convenient to use.

detailed description

Below in conjunction with accompanying drawing, the present invention is described in further detail:

As shown in Figure 1, the frame 1 is provided with a crossbeam 2 that can slide up and down. There is a vertical slider, and the slider is matched with a linear guide rail 5 that can slide up and down along the slider. The lower end of the linear guide rail 5 is provided with a probe 6; the cross section of the fixed base 4 is L-shaped, and the lower part of the fixed base 4 is connected to the beam 2 on.

As shown in Figures 2 and 3, the upper part of the fixed base 4 is provided with a transverse pre-tightening through hole, the outer port of the pre-tightening through hole is threaded with an adjusting bolt 7, and the inner port of the pre-tightening through hole is located at the inner bottom of the slider, and The inner port of the pre-tightening through hole is provided with a pre-tightening ball 9, and the pre-tightening through-hole between the pre-tightening ball 9 and the adjusting bolt 7 is provided with a compression spring 10. When the guide rail 5 moves up and down along the slide block, the circular groove 8 that can be opposite to the port in the pre-tightening through hole, the diameter of the pre-tightening ball 9 is greater than the diameter of the circular groove 8. The preload is provided by the compression spring 10 and the adjusting bolt. Under normal circumstances, the compression spring 10 presses the preloaded ball 9 outward, and part of the surface of the preloaded ball 9 is pushed into the circular groove 8 of the linear guide 5. At this time, the preloaded pressure of the preloaded ball 9 can push the linear guide 5 Defined in the slider, when the upward pressure of the linear guide 5 increases beyond the limit value, the linear guide 5 pushes the preloaded ball 9 to one side, causing the linear guide 5 to slide upwards, causing the downward pressure to drop rapidly. By adjusting the depth of the adjusting bolt 7 extending into the pre-tightening through hole, the pre-tightening pressure can be adjusted, thereby providing different critical pressures for the upward sliding of the linear guide rail 5,

When in use, the patient's wrist is placed in the vein-cutting groove 3, the crossbeam 2 descends slowly under the control of the computer, and stops descending when the probe 6 touches the pulse position, and the probe 6 transmits the pulse signal to the computer for analysis. Once out of control occurs in the descending process of the crossbeam 2, when the upward pressure of the linear guide rail 5 by the wrist is greater than the limit value of the upward sliding of the linear guide rail 5, the linear guide rail 5 slides upwards, which reduces the impact force of the linear guide rail 5 on the wrist and starts to the protective effect.

The above description is only the preferred implementation mode of this patent. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of this patent, some improvements and replacements can also be made. These improvements and replacements It should also be regarded as the scope of protection of this patent.
