Pulse Diagnostic Instrument Mechanical Finger

Abstract

The present invention discloses a mechanical finger of a pulse diagnosis instrument, comprising: a column, one end of which is a fixed end and the other end is a free end; a sensor, which comprises a plurality of sensor units for collecting pulse signals; and a rolling element, which is rotatably connected to the free end of the column, the sensor is mounted on the rolling element, and the plurality of sensor units are arranged at intervals along the rotation direction of the rolling element. When the mechanical finger of the pulse diagnosis instrument is searching for a pulse sensing point, the mechanical finger is lowered to the wrist pulse position after preliminary positioning, and the pulse signal collected is used to determine whether it is aligned with the pulse sensing point. If it is not aligned, the rolling element is rolled to drive the plurality of sensor units to roll back and forth on the skin until they are aligned with the pulse sensing point. Since the mechanical finger does not need to be repeatedly lifted and lowered when searching for the pulse sensing point, the alignment speed is very fast.

Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, and in particular to a mechanical finger of a pulse diagnosis instrument. Background Art

[0002] Pulse diagnosis is a diagnostic method of traditional Chinese medicine. After thousands of years of exploration and practice by successive generations of Chinese medicine practitioners, a diagnostic system of 28 pulse conditions has gradually been formed. At present, the main method of pulse diagnosis in Chinese medicine is still for Chinese medicine doctors to feel the patient's pulse with their fingers, and then diagnose the disease based on the doctor's experience and hand touch. This diagnostic method has vague judgment criteria and is easily affected by the doctor's personal experience and subjective factors, leading to misjudgment. It is also impossible to quantify and effectively record the pulse.

[0003] For this reason, pulse diagnosis instruments for diagnosing pulses have appeared on the market. Such pulse diagnosis instruments are mainly composed of a mechanical finger for collecting the pulse information of the person being measured and a host for analyzing and processing the pulse information. The sensing surface of the existing mechanical finger in contact with the skin is a plane. When the mechanical finger is looking for a pulse sensing point, the mechanical finger is first pressed on the wrist pulse position, and the collected pulse signal is used to determine whether it is aligned with the pulse sensing point. If it is not aligned, the mechanical finger needs to be lifted until it is separated from the skin, and then the spatial position of the mechanical finger needs to be adjusted. After adjustment, the mechanical finger is pressed down again. If it is still not aligned, the mechanical finger needs to be lifted again, so the alignment speed is very low. Summary of the invention

DETAILED DESCRIPTION

[0026] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0027] Figure 1 Schematic diagram of the structure of the mechanical finger of the pulse diagnosis instrument in the first embodiment of the present invention, Figure 2 FIG. 1 is an exploded view of the mechanical finger of the pulse diagnosis instrument in the first embodiment of the present invention. Figure 1 , 2 As shown, the pulse diagnosis instrument mechanical finger in this embodiment is mainly composed of a column 1, a rolling element 2 and a sensor 4, wherein the upper end of the column 1 is a fixed end 101, and the lower end of the column 1 is a free end 102. The fixed end 101 of the column 1 is used to connect with a finger driving mechanism (not shown in the figure), and the X, Y, and Z spatial positions of the mechanical finger are adjusted by the finger driving mechanism. The rolling element 2 is rotatably connected to the free end 102 of the column 1. In this embodiment, the lower end of the column 1 is fork-shaped, the rolling element 2 is located between two fork arms 103, and the rolling element 2 is connected to the two fork arms 103 through a rotating shaft 3. The sensor 4 is installed on the rolling surface 201 of the rolling element 2, and the sensor 4 includes a plurality of sensor units (not shown in the figure) for collecting pulse signals, and the plurality of sensor units are arranged at intervals along the rotation direction of the rolling element 2.

[0028] When the mechanical finger of the pulse diagnosis instrument of this embodiment is looking for the pulse sensing point, after preliminary positioning, the mechanical finger is lowered to the wrist pulse position, and the collected pulse signal is used to determine whether it is aligned with the pulse sensing point. If it is not aligned, the rolling element 2 is rolled to drive multiple sensor units to roll back and forth on the skin until they are aligned with the pulse sensing point. Since there is no need to repeatedly lift and put down the mechanical finger when looking for the pulse sensing point, the alignment speed is very fast.

[0029] In one embodiment, the sensor 4 further includes a flexible mounting belt 401, and the multiple sensor units are fixed on the mounting belt 401. The mounting belt 401 is attached to the rolling surface 201 of the rolling element 2, and the mounting belt 401 and the rolling surface 201 of the rolling element 2 can be fixed by, for example, gluing or screwing. This mounting method between the sensor 4 and the rolling element 2 has the advantages of low processing cost and convenient maintenance. As an alternative, the sensor 4 and the rolling element 2 are an integrated structure, and the multiple sensor units of the sensor 4 are directly fixed on the rolling surface 201 of the rolling element 2.

[0030] In order to quickly restore the rolling element 2 to its initial position, the pulse diagnosis instrument mechanical finger further includes a reset mechanism for restoring the rolling element 2 to its initial position. Figure 1 , 2As shown, the reset mechanism in this embodiment includes a first motor 5 and a reset transmission mechanism, wherein the first motor 5 is fixed on the column 1, the input end of the reset transmission mechanism is connected to the output shaft of the first motor 5, and the output end is connected to the rolling element 2. The first motor 5 drives the rolling element 2 to return to the initial position through the reset transmission mechanism. In one embodiment, the reset transmission mechanism includes a pull rope 6, one end of which is fixed to the output shaft of the first motor 5, and the other end is fixed to the rolling surface 201 of the rolling element 2. In this embodiment, a hanging ear 202 is provided on the rolling surface 201 of the rolling element 2 opposite to the mounting surface for mounting multiple sensor units, and the pull rope 6 is vertically arranged, and the lower end of the pull rope 6 is fixed to the hanging ear 202. When the rolling element 2 is in the initial position, the hanging ear 202 is located at the highest position of the rolling element 2. When the first motor 5 is working, its output shaft rotates in the positive direction (such as clockwise and reverse), and the longer the length of the pull rope 6 wrapped around the output shaft is, the tighter the pull rope 6 is, thereby pulling the rolling element 2 to the initial position. The pull rope 6 has the advantages of simple structure and low cost.

[0031] Figure 3 This is a schematic diagram of the structure of the mechanical finger of the pulse diagnosis instrument in the second embodiment of the present invention. Figure 4 FIG. 1 is an exploded view of the mechanical finger of the pulse diagnosis instrument in the second embodiment of the present invention. Figure 3 , 4 As shown, the structure of the mechanical finger of the pulse diagnosis instrument in this embodiment is substantially the same as that of the mechanical finger of the pulse diagnosis instrument in the first embodiment, except that the reset mechanism in this embodiment includes a recess 203, a reset block 7, and a reset drive device arranged on the rolling element 2. In this embodiment, the recess 203 is arranged on the rolling surface 201 at the top of the rolling element 2, and when the rolling element 2 is in the initial position, the recess 203 is located at the highest position of the rolling element 2. The reset block 7 is arranged on the column 1 and can move telescopically between the extended position and the retracted position. The reset block 7 includes a convex portion 701 that cooperates with the recess 203. The reset drive device is used to drive the reset block 7 to move telescopically between the extended position and the retracted position. When the convex portion 701 is extended, the convex portion 701 is inserted into the recess 203 to rotate the rolling element 2 to the initial position.

[0032] In one embodiment, the reset block 7 further includes a top portion 703 and a guide portion 702 located between the top portion 703 and the convex portion 701, a rectangular hole 104 and a guide hole 105 located between the rectangular hole 104 and the fork arm 103 are provided in the middle of the column 1, the top portion 703 is located in the rectangular hole 104, and the guide portion 702 is inserted in the guide hole 105. The movement of the reset block 7 is guided by the guide portion 702 and the guide hole 105.

[0033] Preferably, the concave portion 203 is V-shaped, and the convex portion 701 is V-shaped, which is conducive to the rapid alignment between the convex portion 701 and the concave portion 203. Preferably, the two side walls of the concave portion 203 are convex arcs, and the two side surfaces of the convex portion 701 are concave arcs matching the convex arcs, so that the opening of the concave portion 203 is larger, and even if the rolling element 2 deviates from the column 1 at a large angle, the convex portion 701 can be inserted into the concave portion 203, so that the rolling element 2 is reset to the initial state.

[0034] In one embodiment, the reset drive device includes a second motor 8, a cam 9 and a reset spring 10, wherein the second motor 8 is mounted on the column 1, the cam 9 is mounted on the output shaft of the second motor 8 and is located above the guide portion 702, and the reset spring 10 is disposed between the reset block 7 and the column 1. When the second motor 8 is working, the cam 9 is driven to rotate, and the reset block 7 is driven to move downward, so that the convex portion 701 is inserted into the concave portion 203, and the reset block 7 moves upward under the action of the reset spring 10.

[0035] Figure 5 Schematic diagram of the structure of the mechanical finger of the pulse diagnosis instrument in the third embodiment of the present invention. Figure 6 FIG. 1 is an exploded view of the mechanical finger of the pulse diagnosis instrument in the third embodiment of the present invention. Figure 5 , 6 As shown, the structure of the pulse diagnosis instrument mechanical finger in this embodiment is substantially the same as that of the first embodiment, except that: the pulse diagnosis instrument mechanical finger also includes a rotation drive device for driving the rolling element 2, so that when the sensor unit is not aligned with the pulse sensing point, the rolling element 2 is driven to rotate by the rotation drive device to achieve alignment, which is more convenient. The rotation drive device in this embodiment includes a first driven bevel gear 11, a transmission shaft 12, a first driven bevel gear 11, a second driven bevel gear 14 and a second active bevel gear 15, and the first driven bevel gear 11 is installed on the rolling element 2 and is coaxial with the rotating shaft 3 of the rolling element 2. The transmission shaft 12 extends in the longitudinal direction of the column 1, and the lower end of the transmission shaft 12 is provided with the first driven bevel gear 11 meshing with the first driven bevel gear 11, and the upper end is provided with the second driven bevel gear 14. The second active bevel gear 15 meshes with the second driven bevel gear 14. The driving mechanism is installed on the column 1 to drive the second active bevel gear 15.

[0036] In one embodiment, the driving mechanism includes a first linear slide 16 and a rack 17, wherein the output end of the first linear slide 16 is connected to the rack 17, and the rack 17 is meshed with the second active bevel gear 15. The first linear slide 16 drives the rack 17 to move linearly, and the rack 17 drives the second active bevel gear 15 to rotate, and drives the rolling element 2 to rotate through the transmission shaft 12, the first active bevel gear 13, and the first driven bevel gear 11.

[0037] In one embodiment, the second driven bevel gear 14 is slidably arranged on the transmission shaft 12 between an engagement position and a disengagement position, and the rotation drive device further comprises a second linear slide 18 for driving the second driven bevel gear 14. When the second linear slide 18 controls the second driven bevel gear 14 to disengage from the second active bevel gear 15, the rolling element 2 is in a free state. When the second linear slide 18 controls the second driven bevel gear 14 to mesh with the second active bevel gear 15, the rolling element 2 can be controlled to rotate relative to the column 1, so that the rolling element 2 can roll on the skin and eliminate sliding friction with the skin.

[0038] In summary, when the pulse diagnosis instrument mechanical finger of the present invention is looking for the pulse sensing point, after preliminary positioning, the mechanical finger is lowered to the wrist pulse position, and the collected pulse signal is used to determine whether it is aligned with the pulse sensing point. If there is no alignment, the rolling element drives multiple sensor units to roll back and forth on the skin until they are aligned with the pulse sensing point. Since there is no need to repeatedly lift and put down the mechanical finger when looking for the pulse sensing point, the alignment speed is very fast.

[0039] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
