Description

Technical Field

[0001] This invention relates to the field of skin sampling, and more specifically, to a skin sampling component and testing equipment. Background Technology

[0002] Skin is one of the largest organs in the human body and a major barrier against external environmental factors. The health of the skin has a significant impact on overall health; therefore, skin sampling and analysis are crucial for the diagnosis, treatment, and prevention of skin diseases. Doctors often need to scrape the surface of a patient's skin to collect samples. During this process, skin tissue is easily shed, and holding the sampling container by hand to collect the skin can easily lead to sample infection. Dry skin also causes debris to scatter, making skin sampling difficult.

[0003] For example, the "Skin Sampling Device" disclosed in Chinese Utility Model Patent (Application No.: CN201720603855.2) states in its specification that skin lesion examination and sampling is one of the daily tasks of dermatology. Doctors often need to use a scraper to scrape the patient's skin surface to collect samples for examination in order to diagnose the condition. Existing scrapers are single blades, and skin tissue is easily shed and lost when scraping the skin. When using them, one hand can only hold the scraper while the other hand holds the sampling box to catch it. Since the surface of most skin diseases is relatively dry, skin debris is easily scattered everywhere during sampling, which increases the burden on doctors and is also prone to infection for medical staff. The above patent can corroborate the defects of the existing technology.

[0004] Therefore, we have made improvements to this by proposing a skin sampling component and testing equipment. Summary of the Invention

[0005] The purpose of this invention is to address the current problems of skin tissue easily falling off during skin scraping, the risk of sample infection when holding the sampling box to receive the skin, and the difficulty in skin sampling due to dry skin causing debris to scatter everywhere.

A torsion spring and an inclined plate are respectively fitted on the surface of the rotating rod. A connecting block is connected to one side of the inclined plate and the right side of the inner cavity of the box via a damping rotating shaft. A short pipe is fixedly connected to one side of the connecting block. A connecting frame is rotatably connected to one end of the short pipe. An observation mirror is provided on one side of the connecting frame.

[0014] As a preferred technical solution of this application, the observation mirror is fitted with a winding roller, and the surfaces of the upper and lower winding rollers are wrapped with disinfectant cloth. The winding roller on the left side is used to guide and support the disinfectant cloth. The inner side of the connecting frame is rotatably connected to a support roller.

[0017] An inspection device for testing samples taken by a skin sampling component.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] In the scheme of this application:

[0020] 1. In order to solve the problems in the prior art where skin tissue is easily detached when scraping the skin, the sampling box held by hand to receive the skin is prone to sample infection, and dry skin makes it easy for debris to scatter everywhere, making skin sampling difficult, this application achieves the goal of preventing the skin from falling off after sampling by setting up a sampling mechanism, storing the sampled skin tissue inside a transparent cover, making sampling convenient and efficient.

[0021] 2. Through the sampling mechanism, the function of closed skin sampling is realized. During the skin sampling process, the skin is sucked into the transparent cover. At the same time, the depth of the skin being sucked into the transparent cover can be adjusted, thereby adjusting the thickness of the skin sample, which facilitates better skin sampling and solves the problem of inconvenient adjustment of skin sampling thickness in the existing technology.

[0022] 3. The observation mechanism enables the observation of sampled skin tissue. Multiple observation mirrors can be used for pre-observation of the skin tissue. After the skin tissue passes the observation, it is then tested on the testing equipment. The observation mirrors can be rotated to the outside of the chamber, and one or more observation mirrors can be selected for observation of the skin tissue as needed. At the same time, a sterile cloth can be wrapped around the skin with a winding roller. The sterile cloth comes into contact with the skin, and the sterile solution on the cloth is used to immerse the sampled skin and disinfect the sampling site. This solves the problem that the existing technology cannot observe the sampled skin tissue and disinfect the sampling site.

[0023] 4. The disinfection mechanism enables the supply of disinfectant to the disinfection cloth. The wrapping roller of the disinfection cloth is brought into contact with the absorbent cotton, and the disinfection cloth absorbs the disinfectant, which is then applied to the skin for disinfection. At the same time, the disinfection mechanism can be removed to spray disinfectant on a large area of ​​skin, improving the efficiency of skin disinfection and solving the problem of inconvenience in disinfecting the skin at the sampling site in the existing technology.

[0042] Example 1

[0043] Please refer to Figure 1 , Figure 2 and Figure 3 A skin sampling assembly includes a sampling mechanism 1, which includes a transparent cover 10. A sampling hole 11 is provided at the bottom of the transparent cover 10. A flexible telescopic shell 12 is connected to the middle of the transparent cover 10. A vertical tube 13 is installed through the top of the flexible telescopic shell 12, and the bottom of the vertical tube 13 extends into the interior of the transparent cover 10. A telescopic hose 14 is movably connected to the bottom of the vertical tube 13. The bottom of the telescopic hose 14 is fixedly connected to the bottom of the inner cavity of the transparent cover 10. Connecting plates 15 are fixedly installed on both sides of the vertical tube 13. A telescopic rod 16 is fixedly connected to the bottom of the connecting plates 15. Sampling blades 17 are movably connected to both sides of the bottom of the inner cavity of the flexible telescopic shell 12. A longitudinal groove 18 is provided at the top of the sampling blade 17. A T-shaped slider 19 is slidably connected to the inner cavity of the longitudinal groove 18. The top of the T-shaped slider 19 extends to the top of the sampling blade 17 and is fixedly connected to the bottom of the telescopic rod 16. Cutting holes 110 are provided at the bottom of both sides of the telescopic hose 14 to cooperate with the sampling blade 17.

[0044] By setting a flexible telescopic shell 12, the transparent cover 10 can be extended and retracted. During the extension and retraction process, the skin can be drawn upward into the transparent cover 10, which is convenient for skin sampling. The cross-sectional shape of the longitudinal groove 18 is T-shaped. The T-shaped slider 19 can slide back and forth under the restriction of the longitudinal groove 18, but cannot be disengaged from the longitudinal groove 18. By setting the T-shaped slider 19 and the longitudinal groove 18, the sampling blade 17 can be driven. In conjunction with other structures, the lateral movement of the sampling blade 17 can be realized.

[0045] Example 2

[0046] The skin sampling component provided in Example 1 has been further optimized, specifically, as follows: Figure 4 As shown, transverse grooves 111 are provided on both the front and rear sides of the inner cavity of the transparent cover 10. Slide rods 112 are fixedly connected to both the front and rear sides of the sampling blade 17. The side of the slide rod 112 away from the sampling blade 17 extends into the inner cavity of the transverse groove 111 and is movably connected to the transverse groove 111.

[0047] By setting the transverse groove 111 and the slide bar 112, the sampling blade 17 is guided, which facilitates the lateral movement of the sampling blade 17.

[0048] Furthermore, such as Figure 3As shown, a damping sleeve 113 is fitted between the surface of the vertical tube 13 and the transparent cover 10. The inner wall of the damping sleeve 113 is in contact with the surface of the vertical tube 13. The side of the damping sleeve 113 away from the vertical tube 13 is bonded to the inner wall of the transparent cover 10. A cover 114 is connected to the top right side of the vertical tube 13 by a connecting strip. A circular plate 115 is fixedly fitted to the bottom of the transparent cover 10. A suction cup 116 is fixedly connected to the bottom of the circular plate 115. An observation mechanism 2 is provided through the top of the vertical tube 13.

[0049] By setting a damping sleeve 113, the rotational damping between the vertical tube 13 and the transparent cover 10 is increased, so that the vertical tube 13 is damped and positioned after rotating at a certain angle. By setting a cover 114, the top of the vertical tube 13 can be sealed, which improves the sealing performance inside the transparent cover 10 when sampling skin tissue. By setting a circular plate 115, the bottom of the transparent cover 10 is supported, which improves the stability of the transparent cover 10 when sampling. By setting a suction cup 116, the area around the sampled skin can be sealed, which improves the sealing performance and allows the sampled skin to be better sucked into the transparent cover 10.

[0050] Example 3

[0051] The skin sampling component provided in Example 1 or 2 is further optimized, specifically, as follows: Figure 5 and Figure 6 As shown, the observation mechanism 2 includes a connecting pipe 20. The bottom of the connecting pipe 20 extends through the inner cavity of the vertical pipe 13 and is threadedly connected to the vertical pipe 13. The top of the connecting pipe 20 is connected to a box 21. The left side of the box 21 is connected to a rotating rod 22 via a support block. A torsion spring 23 and an inclined plate 24 are respectively fitted on the surface of the rotating rod 22. A connecting block 25 is connected to one side of the inclined plate 24 and the right side of the inner cavity of the box 21 via a damping rotating shaft. A short pipe 26 is fixedly connected to one side of the connecting block 25. A connecting frame 27 is rotatably connected to one end of the short pipe 26. An observation mirror 28 is provided on one side of the connecting frame 27.

[0052] One end of the torsion spring 23 is fixedly connected to the inclined plate 24, and the other end of the torsion spring 23 is fixedly connected to the support block. By setting the torsion spring 23, a torsion force is generated on the inclined plate 24, which facilitates the return of the inclined plate 24. By setting the damping shaft, the connecting block 25 is damped and supported, which improves the stability of the connecting block 25.

[0053] Furthermore, such as Figure 5 and Figure 6 As shown, the observation mirror 28 is fitted with a winding roller 29, and a disinfectant cloth 210 is wound around the surface of the upper and lower winding rollers 29. The winding roller 29 on the left side is used to guide and support the disinfectant cloth 210. A support roller 211 is rotatably connected to the inner side of the connecting frame 27. The opposite side of the support roller 211 is in contact with the observation mirror 28, and one side of the support roller 211 is in contact with the surface of the disinfectant cloth 210.

[0054] By setting up support roller 211, the disinfection cloth 210 is tensioned and supported, so that the disinfection cloth 210 is always in contact with the surface of the winding roller 29 for transmission, thereby improving the stability of the disinfection cloth 210 during winding.

[0055] A guide post 212 is installed through the inner wall of the connecting frame 27. One end of the guide post 212 passes through the inner cavity of the short tube 26 and is movably connected to the short tube 26. The other end of the guide post 212 is connected through a connecting ring 213. The side of the connecting ring 213 away from the guide post 212 is rotatably connected to a tension wheel 214 through a support block. One side of the tension wheel 214 is in contact with the disinfection cloth 210. A first spring 215 is sleeved on the surface of the guide post 212.

[0056] One end of the first spring 215 is fixedly connected to the inner wall of the connecting frame 27, and the other end of the first spring 215 is fixedly connected to the connecting ring 213. By setting the first spring 215, tension is generated on the connecting ring 213, causing the connecting ring 213 to drive the tensioning wheel 214 to press against the disinfection cloth 210, thereby tensioning the disinfection cloth 210, which facilitates the winding of the disinfection cloth 210. By setting the guide post 212, the connecting ring 213 is guided, which facilitates the lateral movement of the connecting ring 213.

[0057] Example 4

[0058] Please refer to Figure 3 A skin sampling assembly has a disinfection mechanism 3 at the bottom of its winding roller 29, which is used to disinfect the sampled skin.

[0059] Furthermore, such as Figure 7 and Figure 8 As shown, the disinfection mechanism 3 includes a frame 30. A threaded tube is fixedly connected to the bottom of the frame 30, and a liquid storage bottle 31 is threadedly connected to the bottom of the threaded tube. A second spring 32 is welded to the bottom of the inner wall of the frame 30. A support plate 33 is connected to the top of the second spring 32. A moisture-absorbing cotton 34 is placed on the top of the support plate 33. Liquid outlet holes 35 are opened on both sides of the inner wall of the frame 30. The top of the moisture-absorbing cotton 34 contacts the disinfection cloth 210. A first... The first one-way valve 36 has its left end passing through the frame 30 and connected to the nozzle 37. The nozzle 37 is embedded in the interior of the frame 30. The bottom of the frame 30 is connected to the second one-way valve 38 through the liquid inlet pipe. The second one-way valve 38 is located in the inner cavity of the liquid storage bottle 31. Both sides of the bottom of the frame 30 are in contact with the pads 39. One side of the pads 39 is fixedly connected to the inner wall of the box 21. The front side of the box 21 is connected to the box door through the pivot. The front of the box door is fixedly connected to the handle.

[0060] By setting a door, the disinfection mechanism 3 can be easily removed from the box 21 for spray disinfection. The observation mirror 28 can also be rotated to the outside of the box 21 to control the number of observation mirrors 28 inside the box 21, thereby controlling the magnification of the skin tissue for better observation of the sampled skin tissue. The handle facilitates the opening and closing of the door. The pad 39 supports the frame 30 to keep it stable. The second spring 32 generates tension on the support plate 33, facilitating the return of the second spring 32.

[0061] Example 4

[0062] Please refer to Figure 1 and Figure 2 An inspection device for testing samples taken by a skin sampling component.

[0063] The skin sampling component provided by this invention is used as follows:

[0064] S1. Disinfection: Disinfectant is injected into the storage bottle 31 and simultaneously into the inner cavity of the frame 30. The disinfectant in the inner cavity of the frame 30 enters the top of the support plate 33 through the outlet hole 35. The absorbent cotton 34 absorbs the disinfectant, and the top of the absorbent cotton 34 contacts the disinfectant cloth 210, soaking the surface of the disinfectant cloth 210 with disinfectant. The disinfectant cloth 210 between the two upper winding rollers 29 comes into contact with the skin, causing the winding rollers 29 to roll on the skin. The upper right winding roller 29 continuously winds the disinfectant cloth 210, while the lower winding roller 29 continuously releases the disinfectant cloth 210, ensuring that new disinfectant cloth 210 is continuously delivered to the skin for disinfection without causing infection. The disinfectant cloth 210 is replaced after use. When large areas of skin need to be sprayed for disinfection, open the box door, take out the disinfection mechanism 3, press down the absorbent cotton 34 with your finger to move the support plate 33 downward. When the support plate 33 moves down to the bottom of the liquid outlet 35, the air pressure inside the frame 30 increases, causing the first one-way valve 36 to open. The disinfectant is sprayed onto the skin through the first one-way valve 36 and the nozzle 37, which can be used for large-area disinfection. Release your finger, and the second spring 32 will generate tension on the support plate 33, causing the support plate 33 to move upward back to its original position. At this time, the pressure inside the frame 30 decreases, the second one-way valve 38 opens, and the disinfectant in the storage bottle 31 enters the inner cavity of the frame 30 through the second one-way valve 38 and the pipeline to replenish it. Multiple sprays of disinfectant can be performed.

[0065] S2. Skin sampling: The compressed transparent cover 10 drives the flexible telescopic shell 12 into a compressed state. The sampling hole 11 is aligned with the skin to be sampled. The suction cup 116 seals the skin. The transparent cover 10 and the flexible telescopic shell 12 are stretched. At this time, a negative pressure is generated inside the transparent cover 10, causing the skin to be sampled to move upward through the sampling hole 11. The skin to be sampled enters the interior of the transparent cover 10. The height of the flexible telescopic shell 12 is adjusted to control the depth of the skin entering the interior of the transparent cover 10. Then, the vertical tube 13 is rotated to drive the connecting plate 15, the telescopic rod 16 and the T-shaped slider 19 to rotate. The T-shaped slider 19 moves back and forth in the interior of the longitudinal groove 18, so that the two sampling blades 17 come closer to each other. When the two sampling blades 17 come close, the skin inside the transparent cover 10 is sampled. The sampled skin tissue remains at the bottom of the sampling blade 17.

[0066] S3. Observation: Remove the disinfection mechanism 3 from the housing 21. Rotate the lower winding roller 29 to loosen the disinfection cloth 210. Rotating the winding roller 29 causes the observation mirror 28 and the connecting frame 27 to rotate, making the three observation mirrors 28 horizontal. Push the inclined plate 24 to the right, causing the connecting frame 27 and the observation mirrors 28 to move to the right, moving the left observation mirror 28 above the housing 21. At this time, the three observation mirrors 28 are on the same axis. The three coaxial observation mirrors 28 form a magnifying glass device. Looking down from above the observation mirrors 28, magnified skin tissue on the sampling blade 17 can be seen, allowing for preliminary observation of the skin tissue. After inspection and approval, the sampled skin tissue is taken to the testing equipment for testing. When multiple observation mirrors 28 are not needed, release your fingers away from the inclined plate 24. The torsion spring 23 generates torque on the inclined plate 24, causing the inclined plate 24 to return to its original position. The inclined plate 24 drives the upper observation mirror 28 to return to its original position. At this time, two coaxial observation mirrors 28 can be used to observe the skin tissue. Open the box door and rotate the lower observation mirror 28 forward, which drives the connecting frame 27, connecting block 25 and short tube 26 to rotate, so that the observation mirror 28 rotates to the outside of the box 21. At this time, only one observation mirror 28 is located inside the box 21, and the skin tissue can be observed through one observation mirror 28.
