Description

Technical Field

[0001] The present invention relates to the technical field of skin detection, and in particular to a semi-automatic skin elasticity detection device and a use method thereof. Background Art

[0002] The principle of traditional skin elasticity testing is to apply a positive (or negative) pressure on the surface of the skin with a test cavity, push the tested skin outward (or pull it inward) into the test cavity, and then use a non-contact optical detection system to measure the distance scale of pushing away (or pulling in), and finally use a complicated calculation method to infer the elastic performance parameter index of the tested skin based on the measured data. The non-contact optical detection system is a complex, expensive and cumbersome precision instrument. It is too extravagant and wasteful to use it here, and it is completely unnecessary to use a large material for a small purpose. Therefore, it can be seen that designing a semi-automatic skin elasticity detection device and its use method are urgently needed in the current field of skin detection technology. Summary of the invention

[0003] To this end, an embodiment of the present invention provides a semi-automatic skin elasticity detection device and a method of using the same to solve the problems existing in the prior art.

[0004] In order to achieve the above purpose, the embodiment of the present invention provides the following technical solutions:

[0005] According to an embodiment of the present invention, a semi-automatic skin elasticity detection device and a method of using the same include a volumetric metering pump, a sealing cover, positive and negative pressure gauges, and a computer processor terminal. A connecting pipe is fixedly installed at the central position of the bottom of the sealing cover, and the connecting pipe extends to the interior of the sealing cover. A three-way connecting intermediate is fixedly installed at the bottom of the connecting pipe, a positive and negative pressure gauge is fixedly installed on one side of the three-way connecting intermediate, and a connecting pipe is fixedly installed on the other side of the three-way connecting intermediate. A volumetric metering pump is fixedly installed at the bottom of the connecting pipe, and the connecting pipe extends into the interior of the volumetric metering pump. A computer processor terminal is installed at the bottom of the volumetric metering pump via electrical wires, and the electrical wires are quickly connected via connecting buckles.

[0006] Furthermore, a rubber sealing edge is fixedly installed at the edge of the top of the sealing cover, and the rubber sealing edge is made of silicone material.

[0007] Furthermore, the volumetric metering pump is a mechanical device in the form of a rotation driven by electrical energy, and a protective cover is fixedly installed on the front of the volumetric metering pump.

[0008] Furthermore, the sealing cover is made of a rigid transparent material, and the edge of the top is flat and smooth.

[0009] Furthermore, the connecting pipe and the connecting pipeline are soft and stretchable adjustable pipelines.

[0010] A method for using a semi-automatic skin elasticity detection device comprises the following steps:

[0011] Place the sealing cover close to the skin to be tested and in close contact with it. First, set a reasonable positive pressure uPa for the device according to the specific condition of the skin to be tested. Then, the computer processor terminal controls the positive rotation of the positive displacement metering pump to increase the pressure of the system. When the pressure reaches the predetermined target, stop driving and record the driving data x pulses of the rotation of the positive displacement metering pump.

[0012] After the system is restored, a reasonable negative pressure - vPa is reset, and the computer processor terminal controls the positive displacement metering pump to rotate in the opposite direction to reduce the pressure of the system. After the target is reached, the drive is stopped and the drive pulse data y is recorded;

[0013] 1) When the values ​​of data x and y are relatively large, the skin is relatively tight and elastic;

[0014] 2) When the values ​​of data x and y are relatively moderate, the skin elasticity is normal;

[0015] 3) When the values ​​of data x and y are relatively small, the skin is loose and has poor elasticity;

[0016] Among them, the positive pressure value is set to U = 15 scales, of which the full scale is 25 scales, and the corresponding driving pulse number X = 100, that is, the half-turn rotation stroke of the volumetric metering pump is relatively small;

[0017] X = 200, that is, the rotation stroke of the volumetric metering pump is moderate for one revolution;

[0018] X = 300, that is, the rotation stroke of the volumetric metering pump is 1 and a half turns, which is relatively large;

[0019] Similarly, the negative pressure value is set to V = 15 scales, of which the full scale is 25 scales, and the corresponding drive pulse number Y = 100, that is, the half-turn rotation stroke of the volumetric metering pump is relatively small;

[0020] Y = 200, that is, the rotation stroke of the volumetric metering pump is moderate for one revolution;

[0021] Y=300, that is, the rotation stroke of the volumetric metering pump is 1 and a half turns, which is relatively large.

[0022] The present invention has the following advantages:

[0023] 1. The semi-automatic skin elasticity detection device and its use method use a bell-shaped closed space test chamber as the main body for applying positive and negative pressures to perform tests, and are closed and connected to a pressure gauge with positive and negative pressure measurement and display functions, and a computer microprocessor program-controlled and driven volumetric metering pump as an operating means for changing the volume of the closed space and applying positive and negative pressures, to form a whole test system. Through the ideal gas isothermal process, the elastic deformation of the tested skin and the volume change of the test chamber caused by the corresponding positive and negative pressures are obtained, and the elasticity parameter index of the tested skin is indirectly measured through intelligent algorithm processing in conjunction with the computer program-controlled operation data of the volumetric metering pump;

[0024] 2. The semi-automatic skin elasticity detection device and its use method adopt the method of applying positive and negative pressures to non-invasively test the elastic performance index of the health status evaluation index of human skin. Manual observation is combined with computer microprocessor program control operation to realize semi-automatic detection. It can use the method of changing volume to observe the pressure following the change, and can also use the method of changing the pressure value to test the volume change. It is flexible and mobile, and the positive and negative are random and appropriate. The test device used is extremely sophisticated in structure, and the computer microprocessor program control operation can easily realize constant pressure, linear pressure increase, linear pressure reduction and even pulsation mutation and other detection forms. Compared with large-scale precision program control testing methods, it is convenient, fast, simple and easy. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In the present invention: a rubber sealing edge 1 is fixedly installed at the edge of the top of the sealing cover 7, and the rubber sealing edge 1 is made of silicone. The rubber sealing edge 1 is in close contact with the skin to be tested, and the silicone material of the rubber sealing edge 1 avoids the generation of a gap between the sealing cover 7 and the skin, so that the overall sealing performance of the device during use is better.

[0034] In the present invention: the volumetric metering pump 6 is a mechanical device in the form of electric energy driven rotation, and a protective cover 5 is fixedly installed on the front of the volumetric metering pump 6. Furthermore, under the drive of a certain amount of electric energy, the amplitude of the rotational movement of the device is also correspondingly determined. The protective cover 5 effectively protects the safety of the volumetric metering pump 6 during use and improves the service life of the volumetric metering pump 6.

[0035] In the present invention, the sealing cover 7 is made of a rigid transparent material, and the edge of the top is flat and smooth. It is easy to form an airtight structure when it is close to the flexible object to be measured, avoiding the generation of a gap between the sealing cover 7 and the skin, so that the overall sealing performance of the device during use is better.

[0036] In the present invention: the connecting tube 2 and the connecting pipe 4 are soft and stretchable adjustable pipes. During the use of the device, the positions of the connecting tube 2 and the connecting pipe 4 will inevitably shift due to the contact angle between the sealing cover 7 and the human skin. The soft and stretchable connecting tube 2 and the connecting pipe 4 effectively avoid this problem, making the overall use of the device more convenient and the use effect better.

[0037] A method for using a semi-automatic skin elasticity detection device comprises the following steps:

[0038] The sealing cover 7 is placed close to the skin to be tested and in close contact. First, a reasonable positive pressure uPa is set for the device according to the specific condition of the skin to be tested. Then, the computer processor terminal 9 controls the positive rotation of the positive displacement metering pump 6 to increase the pressure of the system. When the pressure reaches the predetermined target, the drive is stopped and the driving data x pulses of the rotation of the positive displacement metering pump 6 are recorded.

[0039] After the system is restored, a reasonable negative pressure -vPa is reset, and the computer processor terminal 9 controls the positive displacement metering pump 6 to rotate in the reverse direction to reduce the pressure of the system. After the target is reached, the drive is stopped and the drive pulse data y is recorded;

[0040] 1) When the values ​​of data x and y are relatively large, the skin is relatively tight and elastic;

[0041] 2) When the values ​​of data x and y are relatively moderate, the skin elasticity is normal;

[0042] 3) When the values ​​of data x and y are relatively small, the skin is loose and has poor elasticity;

[0043] Among them, the positive pressure value is set to U = 15 scales, of which the full scale is 25 scales, corresponding to the number of drive pulses X = 100, that is, the half-turn rotation stroke of the volumetric metering pump 6 is relatively small;

[0044] X = 200, that is, the rotation stroke of the volumetric metering pump 6 is one turn, which is moderate;

[0045] X = 300, that is, the rotation stroke of the volumetric metering pump 6 is one and a half revolutions, which is relatively large;

[0046] Similarly, the negative pressure value is set to V = 15 scales, where the full scale is 25 scales, corresponding to the number of drive pulses Y = 100, that is, the half-turn rotation stroke of the volumetric metering pump 6 is relatively small;

[0047] Y = 200, that is, the rotation stroke of the volumetric metering pump 6 is one turn, which is moderate;

[0048] Y=300, that is, the rotation stroke of the volumetric metering pump 6 is one and a half revolutions, which is relatively large.
