Detailed Description

By combining the above technical features, the main functions of the pulse diagnosis instrument of the present invention will be clearly demonstrated in the following embodiments.

Referring to fig. 1, a three-dimensional external view of the pulse diagnosis apparatus of the present embodiment is disclosed, the pulse diagnosis apparatus of the present invention is mainly used for measuring a vessel a1 of a to-be-measured portion a, and in detail, the vessel a1 is a radial artery vessel a1 located at a wrist position, and a plurality of to-be-measured portions a (i.e., cun, guan, and chi positions of the chinese medicine theory) are located along an extending direction of the radial artery vessel, although the present invention mainly uses the chinese medicine theory to measure cun, guan, and chi positions of the wrist radial artery vessel a1 as an example, the present invention does not exclude the possibility of measuring other vessels a 1.

Referring to fig. 2, the pulse diagnosis instrument mainly comprises: three artificial fingers 1, three array sensors 2, a control module 3 and an analysis module 4, wherein:

each

artificial finger

1A, 1B, 1C has at least three degrees of freedom of displacement in axial directions, wherein the three axial directions include an X-axis direction defined as a direction substantially parallel to the vessel a1, a Y-axis direction defined as a direction substantially horizontally perpendicular to the vessel a1, and a Z-axis direction defined as a direction that is commonly perpendicular to the X-axis direction and the Y-axis direction. The

artificial fingers

1A, 1B and 1C have three sets of electric control displacement modules, and the electric control displacement modules are mounted on a fixed base 12.

For the sake of simplicity, the electrical control displacement module of one of the artificial fingers 1C is taken as a representative description, and the electrical control displacement module of the artificial finger 1C has three

displacement platforms

111A, 111B, 111C and three driving

units

112A, 112B, 112C respectively connected to the

displacement platforms

111A, 111B, 111C to provide the axial, Y-axial and Z-axial displacements of the artificial finger 1 CX. Taking one set of the electrically controlled displacement modules as an example, the displacement platform 111A in the Y-axis direction is provided with a displacement platform 111B in the X-axis direction, the displacement platform 111B in the X-axis direction extends outward to be connected with a displacement platform 111C in the Z-axis direction, and each of the

displacement platforms

111A, 111B, and 111C is controlled by the driving unit 112a112B112C, so that the artificial finger 1C has three degrees of freedom in displacement in the X-axis direction. It should be noted that the displacement platform 111C of the artificial finger 1C is detachably combined with the displacement platform 111B, so that the sensing surface 21 of the artificial finger 1C can measure the vessels (such as carotid artery) at the positions other than the wrist, the artificial finger 1C is not limited to measure the vessels at the wrist, and the practicability of the pulse diagnosis instrument is improved.

Preferably, the fixed base 12 further has a first electrically controlled displacement platform 121 and a second electrically controlled displacement platform 122 for providing relatively large Y-axis displacement and Z-axis displacement, respectively, to move the electrically controlled displacement modules together, so as to improve the efficiency of displacement adjustment of the

artificial fingers

1A, 1B, and 1C. Since the sizes of the wrist circumference, the forearm circumference, the elbow length and the width of the armpit can affect the placing position of the tested person by several centimeters due to different individual differences of the arms, the first electrically controlled displacement platform 121 and the second electrically controlled displacement platform 122 with relatively large displacement are used to assist the adjustment in a more efficient manner. However, the three-dimensional displacement techniques are quite various and will not be described herein, for example, the

artificial fingers

1A, 1B, and 1C may only provide one-dimensional or two-dimensional movement, and provide corresponding two-dimensional and one-dimensional movement to the to-be-measured portion a, so as to achieve the purpose of adjusting the position relatively. The above-mentioned electric control displacement platform and electric control displacement module are mainly an electromechanical control system formed by a mechanical platform, a servo motor, a power converter, and a Digital Signal Processor (DSP), which is a conventional technology and therefore not described in detail.

Referring to fig. 3A and 3B, each

artificial finger

1A, 1B, 1C has a bottom end, at least one array sensor 2 is disposed at the bottom end of the artificial finger 1B, the array sensor 2 is disposed at the bottom end of each

artificial finger

1A, 1B, 1C in this embodiment, each array sensor 2 includes a sensing surface 21, the area of the sensing surface 21 has a width relatively larger than the width of the vessel a1 [ in detail, the normal human cun, guan, and chi vessels have a length of about 3 cm and a width of 0.6 cm, so the area of the sensing surface 21 can be designed to be about 1 xcm 0.8cm ], the sensing surface 21 has a plurality of first sensing units 211 and at least one second sensing unit 212 distributed in an array, the first sensing unit 211 is a pressure sensing unit, the second sensing unit 212 is an ultrasonic vessel level sensing unit 213 or/and a physiological signal sensing unit 214, in this embodiment, the second sensing unit 212 includes an ultrasonic vascular level sensing unit 213 and a plurality of physiological signal sensing units 214.

In the present embodiment, the static pressure sensor and the dynamic pressure sensor of the first sensing unit 211 are the same component, such as but not limited to a capacitive pressure sensor, so as to save the spot distribution space. Of course, the pressure Sensor may be a static pressure Sensor, such as but not limited to a load cell, or a dynamic pressure Sensor, such as but not limited to a Silicon Piezoresistive sensing material (Silicon Piezoresistive sensing material), piezoelectric material, etc., which mainly aims to measure the static pressure and the dynamic pressure of the site a to be measured, the static pressure refers to a pressure value at which the pulse wave does not pass through the measurement position, that is, a value at which a time-varying amount of the pressure value is substantially consistent, but not a value at which the pulse wave passes through the measurement position, and the dynamic pressure refers to a waveform of the X direction, the Y direction and the amplitude generated by the time-varying frequency wave of the pulse wave pressure. Preferably, the first sensing units 211 are distributed in an array with the vascular sensing unit 213 as the center, so that the

artificial fingers

1A, 1B, 1C can analyze the displacement amount more accurately according to the data obtained by the vascular sensing unit 213.

The physiological signal sensing unit 214 is any one or a combination of a temperature sensing unit, an electromyography sensing unit, a gravity accelerometer, and a sound sensing unit, in the embodiment, the physiological signal sensing unit 214 is, for example, but not limited to, a temperature sensing unit 214a and an electromyography sensing unit 214b, the temperature sensor 214a is used to measure the hand temperature, since the hand temperature is also one of the references for the diagnosis in traditional Chinese medicine, and the electromyography sensor 214b is used to measure the muscle response near the vessel a 1.

The control module 3 is connected to the

artificial fingers

1A, 1B, 1C for controlling the

artificial fingers

1A, 1B, 1C to make the sensing surface 21 of the

artificial fingers

1A, 1B, 1C press against the to-be-measured portion a to sense a pressure value of the to-be-measured portion a.

The analysis module 4 is connected to the control module 3 for outputting a pulse diagnosis message according to the pressure value and a sensing result obtained by the ultrasonic vascular level sensing unit 213 or/and a physiological signal sensing unit 214. Preferably, the control module 3 further includes an interpolation operation unit 31, which is used to calculate the static pressure value and the dynamic pressure value of the sensing surface 21 at the position of the second sensing unit 212 by interpolation using the pressure data of the first sensing units 211 at four points, i.e. the upper, the lower, the left, and the right, in the array sensor 2, so that the pulse diagnosis apparatus can provide more various detection data, and can also ensure the integrity of the pressure data.

Preferably, the device further comprises a floating-sinking position testing means, and the vascular information detecting means specifically comprises a compression depth testing unit 32 connected with the control module 3. Referring to fig. 4A and 4B, when the pressing depth test unit 32 measures the pressure value at the to-be-measured portion a, the control module 3 controls three axial displacement degrees of freedom of the artificial finger 1, and adjusts the depth (as shown in fig. 7) of the sensing surface 21 of the artificial finger 1 pressing on the to-be-measured portion a, so as to calculate a plurality of measurement positions. The number of measurement locations may provide multiple levels of variation in depth in the Z-axis depending on the user's needs (e.g.: three orders (corresponding to the position of floating and sinking in TCM), five orders and eight orders).

Taking three-step variation as an example, the measurement positions measured by the pressing depth test unit 32 include: a first measured depth position (floating, for example, touching the skin without affecting the width W and thickness D of the vessel, i.e., the position where the vessel is not deformed) at which the static pressure value of the vessel at the site A to be measured is the minimum and the dynamic pressure value is the minimum, a second measured depth position (sinking, for example, collapsing to a vessel through which no blood flows) at which the static pressure value of the vessel is relatively large and the dynamic pressure value is the minimum, and a position intermediate the first measured depth position and the second measured depth position are measured as a third measured depth position (middle). The fifth order and the eighth order are that three measuring depth positions and six measuring depth positions are further added between the first measuring depth position and the second measuring depth position at equal intervals or at unequal intervals respectively.

The floating and sinking position of the three parts of the traditional Chinese medicine can be standardized by the floating and sinking position testing means. However, the above-mentioned standardization of floating and sinking positions in traditional Chinese medicine is not limited thereto, if an ultrasonic vessel level sensing unit 213 capable of measuring the vessel thickness D of the vessel a1 is provided in each sensing surface 21, and the control module 3 further includes a pressing depth calculating unit 33, the pressing depth calculating unit 33 calculates a plurality of measuring positions according to the thickness D of the vessel a 1. The measurement position calculated by the pressing depth calculating unit 33 can also provide multi-level variation of different depths on the Z-axis according to different requirements of the user.

Taking the third order variation as an example, the measurement positions calculated by the pressing depth calculating unit 33 include: the first depth measurement position (floating) of the highest position of the vessel a1, the second depth measurement position (sinking) of the lowest position of the vessel a1, and the third depth measurement position are located between the first depth measurement position and the second depth measurement position of the middle position of the vessel a1, thereby achieving the purpose of standardizing the floating and sinking positions of the traditional Chinese medicine.

Preferably, the second sensing unit 212 on the sensing surface 21 further comprises an acoustic sensor for indirectly measuring the thickness D of the vessel A1 (the larger the amount of the vessel A1 is pressed, the larger the sound is), and indirectly estimating the floating, middle and sinking positions according to the sound difference when blood passes through the vessels A1 with different degrees of closure. In addition, if the sound sensor matches the pressure measured by the pressure sensing unit of the first sensing unit 211, the systolic pressure and the diastolic pressure of the vessel a1 can be further obtained. It should be noted that the sound sensor is not limited to being disposed on the sensing surface 21, and if the sound sensor is disposed adjacent to the sensing surface 21, the sound difference of the blood passing through the vessels a1 with different degrees of closure can be measured.

Also, the above-mentioned means are not limited to be implemented individually, and if a plurality of types (for example, the pressure sensing unit having the ultrasonic vascular level sensing unit 213 and the first sensing unit 211, and the sound sensor) are combined, a more precise floating and sinking position can be analyzed.

Preferably, the distance between the sensing surface 21 of the artificial finger a and the vessel a1 is measured by the ultrasonic vessel level sensing unit 213 to generate a difference information. Here, referring to the second and fifth figures in combination, the pulse diagnosis apparatus further includes a hand posture adjustment device 5 connected to the control module 3, the to-be-measured portion a is disposed on the hand posture adjustment device 5, so that the hand posture adjustment device 5 can adjust an inclination of the to-be-measured portion a with respect to the sensing surface 21, the control module 3 further includes an inclination amount calculation unit 35 connected to the control module 3, the inclination amount calculation unit 35 is configured to calculate a difference between differences of the sensing surfaces 21 to obtain data of an inclination amount, the control module 3 controls the hand posture adjustment device 5 according to the inclination amount, and adjusts the inclination of the hand posture adjustment device 5, so that a distance between a vessel a1 of the to-be-measured portion a and the sensing surface 21 tends to be consistent.

Specifically, the hand posture adjusting device 5 includes a fixed base 51, a support 52 disposed on the fixed base 51, and a bracket 53 pivotally connected to the support 52, the support 52 has a recess 521 designed according to the arm type for the patient to place the arm, the bracket 53 is used for placing the hand, the fixed base 51 is provided with a first driving member 511 connected to the control module 3 and a linking member 512 connected to the first driving member 511 and the bracket 53, so as to link the linking member 512 through the first driving member 511, so as to make the bracket 53 swing relative to the support 52, so as to adjust the swing degree of the hand, so as to adjust the vessel a1 to be horizontal, because the vessel in the inch-off size is kept at the same horizontal level as possible according to the result of pulse diagnosis in 2012, the pulse wave sinking criterion can be verified successfully, but the means for keeping the vessel in the inch-off size a1 at the same level as possible is not limited, the bracket 53 may be raised or lowered directly by the cylinder without pivoting the bearing 52, and related technical means are various and not described herein, and the main purpose is to adjust the swinging degree of the hand.

Preferably, the hand posture adjusting device 5 can also be used for adjusting a rotation amount of the to-be-measured portion a in the axial direction, so as to avoid an excessive deviation of the angle of the radial artery from the sensing surface 21. Specifically, the socket 52 has a first adjusting portion 522, and the fixed base 51 has a second driving member 513 connected to the control module 3 and a second adjusting portion 514 connected to the second driving member 513 and the first adjusting portion 522. More specifically, the first adjusting portion 522 has a plurality of teeth, and the second adjusting portion 514 is a gear for engaging the teeth, so as to adjust the rotation amount of the hand more precisely, but the adjusting technical means is not limited thereto, and the bearing 52 may be axially connected to the second driving member 513, so that the bearing 52 can directly rotate around the axial direction, and the related technical means is various and is not limited to automatic or manual operation, which is not described herein again, and the main purpose is to adjust the rotation amount of the hand.

The hand posture adjusting device 5 preferably further comprises an adjusting base 54 with a relatively large displacement between the fixed base 51 and the supporting base 52, because the elbow length will affect the placing position of the arm of the tested person by several centimeters due to the difference of the individual arm sizes, so that the adjusting base 54 with a relatively large displacement can be provided, thereby improving the convenience of adjustment. The adjustment base 54 is adjusted manually in this embodiment rather than automatically by a motor, but automatic adjustment by a motor is also possible. The hand posture adjusting device 5 can improve the defects of the traditional Chinese medicine that the stability and the accuracy are not enough only by using a small pillow.

Preferably, the medical pulse taking device further comprises a movement detecting unit 6, wherein the movement detecting unit 6 is connected to the control module 3 for sensing three axial displacement amounts of the

artificial fingers

artificial fingers

1A, 1B, 1C or the pulse taking by the doctor. For the sake of brevity, the details of the film displacement sensing unit disclosed in the inventor I419676 "pulse diagnosis platform for traditional chinese medicine" will not be described in detail.

Since the array sensor of the artificial finger 1 is provided with non-pressure sensing elements (such as a vascular measurement unit, a temperature sensing unit, a myoelectric sensing unit, etc.) on the sensing surface 21 (see fig. 3B), it can provide more comprehensive data about the to-be-measured region for the diagnostician, and is helpful for more accurately adjusting the floating and sinking positions of the pressing during pulse diagnosis.
