Description

Technical Field

[0001] The present invention relates to the technical field of measuring devices, and particularly to a subcutaneous fat measuring clip. Background Art

[0002] Liposuction surgery, that is, fat aspiration surgery, is a method of using instruments to extend through small skin incisions into the subcutaneous fat layer to aspirate fat fragments for the purpose of fat absorption, and is applicable to body shaping.

[0003] Before liposuction surgery, it is necessary to measure the thickness of the fat in this area. The main methods of measurement in clinical work are the pinch method (caliper method) for measuring subcutaneous fat thickness and color Doppler (color ultrasound method) for measuring subcutaneous fat thickness.

[0004] When measuring the skin fold thickness by the caliper method, the measurer uses the left thumb and index finger to pinch the skin and the entire subcutaneous fat layer at the measured part of the subject, holds the caliper with the right hand, inserts the two feet of the caliper into both sides of the pinched skin fold to the bottom, keeps the two feet of the caliper in close contact with the skin, clamps and measures its thickness and records it. However, only using the existing calipers for subcutaneous fat measurement has low accuracy. Summary of the Invention

[0005] In view of the above problems, the present invention is proposed to provide a subcutaneous fat measuring clip that overcomes the above problems or at least partially solves the above problems.

[0006] The subcutaneous fat measuring clip includes a first arm body and a second arm body. The first arm body can approach and move away from the second arm body. The first end of the first arm body and the second end of the second arm body are oppositely arranged and can jointly clamp the outer surface of the skin. The first end is provided with a first current electrode and a first voltage electrode, and the second end is provided with a second current electrode and a second voltage electrode.

[0007] The subcutaneous fat measuring clip further includes a rebound restraint mechanism. The rebound restraint mechanism includes an elastic member connected to the first arm body and a lock body for defining the position of the fixed part of the elastic member. The elastic member can move with the first arm body. After the position of the fixed part of the elastic member is locked, the first arm body can move away from the second arm body under the action of the skin rebound force until it stops moving under the action of the reverse force of the elastic member.

[0008] The subcutaneous fat measuring clip further includes a current supply unit and a voltage detection element. The current supply unit is electrically connected to the first current electrode and the second current electrode, and is configured to provide a preset current to the first current electrode and the second current electrode. The voltage detection element is electrically connected to the first voltage electrode and the second voltage electrode, and is configured to detect the voltage information between the first voltage electrode and the second voltage electrode when there is a current between the first current electrode and the second current electrode and the first arm body stops moving under the reverse acting force of the elastic member.

[0009] The subcutaneous fat measuring clip further includes a distance acquisition unit, a calculation unit, and a display unit. The distance acquisition unit is configured to acquire the distance information between the first end portion and the second end portion when the first arm body stops moving under the reverse acting force of the elastic member. The calculation unit is electrically connected to the voltage detection element, the distance acquisition unit, and the display unit, and is configured to calculate the subcutaneous fat thickness based on the voltage information, the preset current intensity, and the distance information and send it to the display unit.

[0010] In one embodiment, the subcutaneous fat measuring clip further includes a housing. The housing is movably connected to the first arm body. A slider portion protrudes outward from the outer side surface of the first arm body. The housing is formed with a linear guide groove that cooperates with the slider portion. The housing is fixedly connected to the second arm body.

[0011] In one embodiment, the housing is formed with a linear groove body that cooperates with the elastic member. The linear groove body is arranged in parallel with the linear guide groove. The elastic member is a spring. One end of the spring is fixedly connected to the first arm body through a connecting rod, and the other end is fixedly connected to the lock body. The connecting rod is arranged in parallel with the linear guide groove and extends into the linear groove body to be fixedly connected to the elastic member. A plurality of positioning holes are formed at the bottom of the direct groove body and are arranged along the extending direction of the linear groove body. The lock tongue of the lock body can extend into and leave the positioning holes.

[0012] In one embodiment, the voltage detection element is composed of a voltage sensor and an A / D converter.

[0013] In one embodiment, the calculation unit is a single-chip microcomputer.

[0014] In one embodiment, the housing is provided with a scale for marking the distance between the first end portion and the second end portion. The distance acquisition unit is an input panel.

[0015] In one embodiment, the distance acquisition unit is composed of a position sensor and an A / D converter.

[0016] For the subcutaneous fat measuring clip of the present invention, during actual measurement, the measurer can pinch the skin and the entire layer of subcutaneous fat at the measured part of the subject with the left thumb and index finger, hold the subcutaneous fat measuring clip with the right hand and move the first arm body to make the first end and the second end jointly clamp the outer surface of the skin. Subsequently, the fixing part of the elastic member is position-limited by the lock body, and the hand leaves the first arm body. The first arm body moves away from the second arm body under the action of the skin's resilience force until it stops moving under the action of the reverse force of the elastic member. In this state, the subcutaneous fat on both sides of the clamped skin fits or is close to fitting, and at the same time the fat is in a non-compressed state or basically in a non-compressed state, so that the measurement is closer to the true value. Since the fat impedance is positively correlated with the fat thickness, the calculation unit can calculate the subcutaneous fat thickness based on the voltage information, the preset current intensity, and the distance information. Compared with determining the subcutaneous fat thickness only by measuring the distance between the first end and the second end, its accuracy is higher.

[0017] The subcutaneous fat measuring clip of the present invention has high measurement accuracy and is convenient to use. Description of the Drawings

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] A subcutaneous fat measurement clamp according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0026] See Figure 1 , a subcutaneous fat measurement clamp according to an embodiment of the present invention includes a housing 1, a first arm body 2, a second arm body 3, a rebound restraint mechanism 4, a current supply unit 5, a voltage detection element 6, a distance acquisition unit 7, a calculation unit 8, and a display unit 9. The housing 1 provides an installation platform or installation space for other components, and it can be prepared from plastic, metal, or other suitable one or more materials.

[0027] The first arm body 2 can approach and move away from the second arm body 3. The first end portion 10 of the first arm body 2 and the second end portion 11 of the second arm body 3 are arranged opposite to each other and can jointly clamp the outer surface of the skin.

[0028] Specifically, the lower parts of the first arm body 2 and the second arm body 3 extend into the internal installation space of the housing 1 through corresponding openings. Among them, the first arm body 2 is movably connected to the housing 1. A slider portion 12 protrudes outward from the outer side surface of the first arm body 2, and a linear guide groove 13 that cooperates with the slider portion 12 is formed on the housing 1. Thus, the first arm body 2 can linearly move relative to the housing 1 under the action of an external force within a defined trajectory. Of course, other suitable structures can also be adopted between the housing 1 and the first arm body 2 to ensure that the first arm body 2 can linearly move relative to the housing 1 under the action of an external force within a defined trajectory. The second arm body 3 is fixedly connected to the housing 1. Thus, when the first arm body 2 linearly moves relative to the housing 1, it can approach and move away from the second arm body 3.

[0029] Corresponding Figure 1 From a corresponding perspective, the first end portion 10 and the second end portion 11 are located on the same horizontal plane. When the first arm body 2 approaches the second arm body 3, that is, when the first arm body 2 moves to the right, the distance between the first end portion 10 and the second end portion 11 decreases, so that the outer surface of the skin can be clamped. When the first arm body 2 moves away from the second arm body 3, that is, when the first arm body 2 moves to the left, the distance between the first end portion 10 and the second end portion 11 increases, so that it can be separated from the outer surface of the skin.

[0030] The first end portion 10 is provided with a first current electrode 14 and a first voltage electrode 15, and the second end portion 11 is provided with a second current electrode 16 and a second voltage electrode 17. The current supply unit 5 can be arranged in the installation space of the housing 1. The current supply unit 5 is electrically connected to the first current electrode 14 and the second current electrode 16 and is used to provide a preset current to the first current electrode 14 and the second current electrode 16, such as providing an alternating current with a preset intensity or a direct current with a preset intensity.

[0031] The voltage detection element 6 can be arranged in the installation space of the housing 1. The voltage detection element 6 is electrically connected to the first voltage electrode 15 and the second voltage electrode 17 and can detect the voltage information between the first voltage electrode 15 and the second voltage electrode 17 when there is a current between the first current electrode 14 and the second current electrode 16. In one embodiment, the voltage detection element 6 can be composed of a voltage sensor and an A / D converter.

[0032] The rebound restraint mechanism 4 includes an elastic member 18 connected to the first arm body 2 and a lock body 19 for defining the position of the fixed portion of the elastic member 18. The elastic member 18 can move with the first arm body 2. After the position of the fixed portion of the elastic member 18 is locked, the first arm body 2 can move away from the second arm body 3 under the skin rebound force until it stops moving under the reverse force of the elastic member 18.

[0033] Specifically, the housing 1 may be formed with a linear groove body 20 that cooperates with the elastic member 18, and the linear groove body 20 is arranged in parallel with the linear guide groove 13. The elastic member 18 may be a spring, one end of which is fixedly connected to the first arm body 2 through a connecting rod 21, and the other end (i.e., the fixed portion) is fixedly connected to the lock body 19. The connecting rod 21 is arranged in parallel with the linear guide groove 13 and extends into the linear groove body 20 to be fixedly connected to the elastic member 18. A plurality of positioning holes 22 are formed at the bottom of the direct groove body and are arranged along the extending direction of the linear groove body 20. The lock tongue of the lock body 19 can extend into and out of the positioning holes 22. During actual measurement, the measurer can pinch the skin and subcutaneous fat layer at the measured part of the subject with the left thumb and index finger, hold the subcutaneous fat measuring clip with the right hand and move the first arm body 2 so that the first end portion 10 and the second end portion 11 jointly clamp the outer surface of the skin. Subsequently, the lock tongue of the lock body 19 is extended into the positioning hole 22 corresponding to the position where it is located, such as pressing the lock body 19 to extend the lock tongue into the positioning hole 22 corresponding to the position where it is located, and the hand leaves the first arm body 2. The first arm body 2 moves away from the second arm body 3 under the skin rebound force until it stops moving under the reverse force of the elastic member 18. In this state, the subcutaneous fat on both sides of the clamped skin fits or is close to fitting, and at the same time, the fat is in a non-compressed state or basically in a non-compressed state, so that the measurement is closer to the true value.

[0034] The voltage detection element 6 specifically detects the voltage information between the first voltage electrode 15 and the second voltage electrode 17 when there is a current between the first current electrode 14 and the second current electrode 16 and the first arm body 2 stops moving under the reverse force of the elastic member 18.

[0035] The distance acquisition unit 7 is configured to acquire the distance information between the first end 10 and the second end 11 when the first arm body 2 stops moving under the action of the reverse acting force of the elastic member 18. The calculation unit 8 is electrically connected to the voltage detection element 6, the distance acquisition unit 7, and the display unit 9. Since the fat impedance is positively correlated with the fat thickness, the calculation unit 8 can calculate the subcutaneous fat thickness according to the voltage information, the preset current intensity, and the distance information. Compared with determining the subcutaneous fat thickness only by measuring the distance between the first end 10 and the second end 11, its accuracy is higher. The calculation unit 8 sends the calculated subcutaneous fat thickness to the display unit 9 for display by the display unit 9. The calculation unit 8 can be a single-chip microcomputer and is arranged in the installation space of the housing 1. The display unit 9 can be a display screen and is arranged outside the housing 1 or in the installation groove formed by the housing 1.

[0036] In one embodiment, a scale for marking the distance between the first end 10 and the second end 11 is provided on the housing 1 (not shown in the figure). The measurer can read the distance between the first end 10 and the second end 11 when the first arm body 2 stops moving under the action of the reverse acting force of the elastic member 18 through the scale and input the distance information to the distance acquisition unit 7. The distance acquisition unit 7 can be an input panel. In another embodiment, the distance acquisition unit 7 can be composed of a position sensor and an A / D converter.
