Description

Technical Field

[0001] This invention relates to the field of skin sampling tools, and particularly to a sampler for skin lesions in patients with eczema. Background Technology

[0002] Eczema, a common chronic inflammatory skin disease, not only causes patients persistent physical discomfort such as itching, erythema, and oozing due to its recurrent nature, but may also lead to psychological problems such as anxiety and depression, seriously affecting their quality of life. In particular, the incidence rate among children is as high as 10%-20%, and the protracted course of the disease in adult patients exceeds 60%, placing a heavy burden on the public health system.

[0003] Chinese patent CN202320829852.6 discloses a skin lesion sampling device, including a grip and a sampling blade head. The sampling blade head is installed at the bottom of the grip, and the grip and the sampling blade head are movably connected. The grip and the sampling blade head are detachably connected through an installation mechanism. The sampling blade head includes a whistle-shaped blade seat, a scraping blade, and a sampling double-sided adhesive plate. A fitting groove is provided on one side of the end of the whistle-shaped blade seat.

[0004] Based on the aforementioned existing technology, it has been found that the severity of eczema varies from patient to patient, and the presenting conditions differ. For example, during the acute phase of eczema, erythema, papules, and vesicles often appear at the lesion site. After the vesicles rupture, serous exudate will be released. Secondly, when eczema is in the subacute or chronic stage, desquamation will appear on the skin surface. These scales are mostly white or grayish-white, dry and thin in texture, and appear in flakes or powder. Thirdly, if the exudate of eczema dries, it will form a crust on the skin surface. If sampling is not performed according to the corresponding condition of eczema, it will lead to slow sampling and affect the results of subsequent sample testing. Summary of the Invention

There are at least two sets of cutting blades, and the two sets of cutting blades are located inside the two baffles. Each set of cutting blades is symmetrically distributed on the upper and lower sides of the two baffles. Each of the cutting blades is provided with a second push rod on the side facing the baffle. The ends of the multiple second push rods away from the cutting blades are fixedly connected to the inner wall of the baffle. The second push rods can drive the cutting blades to move along the inside of the baffle towards the middle area of ​​the sliding tube. The purpose of cutting and sampling the lesion is achieved through the cooperation of multiple cutting blades on the left and right sides of the inner wall of the cutting chamber with the second push rods.

[0010] Preferably, the protective housing has a placement chamber near the outer side of the sliding tube, and a micro motor is installed inside the placement chamber. The output end of the micro motor is connected to the outer surface of the limiting ring via a pulley.

[0011] Preferably, a handle shell is fixedly provided at the bottom of the protective shell, and the handle shell is fixedly connected to the protective shell.

[0014] The technical effects and advantages of this invention are as follows: 1. This invention uses a detection mechanism to accurately identify the condition of the skin lesion, and combines the differentiated operation of multiple cutting blades in the cutting mechanism to achieve corresponding sampling for different conditions such as acute exudation, subacute, chronic desquamation and crusting. This solves the problem of slow sampling and affected test results caused by the difference in eczema condition in the prior art, and improves sampling efficiency and accuracy.

[0015] 2. The beneficial effects of the present invention are also reflected in the structural optimization and functional synergy in many aspects. First, the combined design of the protective shell and the handle shell not only provides stable protection for the internal detection mechanism and the cutting mechanism, but also enhances the grip friction through the arc design of the handle surface, reducing the risk of slipping or displacement during operation and improving the stability of the sampling process. Secondly, in the cutting mechanism, the cooperation of the sliding tube, the limiting ring and the push rod enables the cutting chamber to rotate at multiple angles and move precisely. With the sealing protection of the rubber ring, it can not only ensure the positional accuracy during cutting and sampling, but also reduce additional irritation to the patient's skin. The symmetrical arrangement of multiple cutting blades and baffles, combined with the drive control of the second push rod, can flexibly adjust the cutting range and force to meet the sampling needs of different skin lesion states. It can form a receiving groove to prevent loss of liquid exudate, can achieve stable clamping of powder or sheet tissue, and can ensure the integrity of sampling by cutting the scab in stages. In addition, the visual inspection equipment of the testing agency, together with the electronic LCD screen, enables real-time observation and data feedback of the skin lesion status. The design of the protective chamber and cleaning unit, through electromagnets and magnetic blocks to control the movement of the cleaning plate, effectively removes impurities and liquids from the surface of the observation mirror, ensuring a clear field of view and avoiding the impact of obstructed field of view on the accuracy of the test.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0019] This invention provides, for example Figures 1 to 9 The eczema patient skin lesion sampling device shown includes a sampling device body 1. The sampling device body 1 is equipped with a detection mechanism 3 and a cutting mechanism 2. The detection mechanism 3 is used to observe the state of the patient's skin lesion and to provide the sampling position and depth to the cutting mechanism 2. The cutting mechanism 2 performs sampling and cutting according to the position of the patient's skin lesion detected by the detection mechanism 3 and the required sampling depth.

[0020] The detection mechanism 3 includes a drive plate 304, and the surface of the drive plate 304 is provided with a visual detection device for detecting the location and depth of the patient's skin lesion. An adjustment plate 305 is provided on the side of the visual detection device facing the drive plate 304, and multiple guide rods 306 are provided inside the adjustment plate 305. The multiple guide rods 306 pass through the interior of the adjustment plate 305 and are set on the surface of the drive plate 304. A linear pushing device 301 is provided on the side of the drive plate 304 facing the adjustment plate 305. The linear pushing device 301 can control the adjustment plate 305 to slide along the outer surface of the guide rods 306. In this way, the distance between the visual detection device and the patient's skin lesion can be adjusted by the movement of the adjustment plate 305, which facilitates the analysis of the location and depth of the patient's skin lesion. This provides the cutting mechanism 2 with an accurate cutting position and appropriate sampling depth. The linear pushing device 301 is a linear push rod or a pneumatic push rod, etc.

[0021] The cutting mechanism 2 includes a sliding tube 203, which is rotatably disposed inside the sampler body 1. A limiting ring 208 is rotatably provided on the sliding tube 203 via a protective shell 101. The inner diameter of the limiting ring 208 is rotatably connected to the outer surface of the protective shell 101. A first push rod 207 is provided on the outer side of the limiting ring 208, and a cutting chamber 201 is provided at the output end of the first push rod 207. A baffle 204 is provided inside the cutting chamber 201, and a second push rod 205 is provided on the inner wall of the baffle 204. The output end is equipped with a cutting blade 206. The second push rod 205 can drive the cutting blade 206 to move along the inside of the baffle 204 towards the center area of ​​the sliding tube 203. The cutting blade 206 can perform sampling on the patient's lesion. The end of the cutting chamber 201 away from the sliding tube 203 is equipped with a rubber ring 202. The rubber ring 202 is used to seal and protect the patient's lesion after contact with the patient's skin. Secondly, the first push rod 207 can push the cutting chamber 201 to move along the surface of the sliding tube 203.

[0022] There are two baffles 204, which are symmetrically arranged on the left and right sides of the inner wall of the cutting chamber 201. There are at least two sets of cutting blades 206, and both sets of cutting blades 206 are located inside the two baffles 204. Each set of cutting blades 206 is symmetrically distributed on the upper and lower sides of the two baffles 204. Each cutting blade 206 has a second push rod 205 on the side facing the baffle 204. The ends of the multiple second push rods 205 away from the cutting blades 206 are fixedly connected to the inner wall of the baffle 204. The second push rods 205 can drive the cutting blades 206 to move along the inside of the baffle 204 towards the middle area of ​​the sliding tube 203. The purpose of cutting and sampling the lesion is achieved through the cooperation of the multiple cutting blades 206 on the left and right sides of the inner wall of the cutting chamber 201 and the second push rods 205.

[0023] The sampler body 1 includes a protective shell 101, which protects the cutting mechanism 2 and the detection mechanism 3 from damage to internal components caused by external forces or impacts, thereby reducing their service life. Furthermore, a placement chamber 103 is provided on the outer side of the protective shell 101 near the sliding tube 203, and a micro motor 105 is provided inside the placement chamber 103. The output end of the micro motor 105 is connected to the outer surface of the limiting ring 208 via a pulley. A protective shell 104 is provided on the outer side of the placement chamber 103, which protects the limiting ring 208 and the output end area of ​​the micro motor 105, preventing damage to the micro motor 105 caused by external forces or other unexpected factors.

[0024] A handle housing 102 is fixedly installed at the bottom of the protective housing 101, and the handle housing 102 is fixedly connected to the protective housing 101. A controller switch is installed inside the handle housing 102, which can control the detection mechanism 3 and the cutting mechanism 2 to work. Furthermore, the surface of the handle housing 102 is provided with multiple arc surfaces, and the multiple arc surfaces are linearly distributed on the surface of the handle housing 102. When medical staff hold the handle housing 102, they can obtain high friction by contacting the multiple arc surfaces, so that it is not easy to fall off or cause displacement during the sampling process. An electronic LCD screen 106 is provided on the side of the protective housing 101 away from the cutting mechanism 2, and the electronic LCD screen 106 is electrically connected to the visual detection device. The electronic LCD screen 106 collects video data through the visual detection device inside the protective housing 101, so that the condition of the patient's lesion can be observed in real time.

[0025] The outer surface of the visual inspection equipment is provided with a protective chamber 311. The protective chamber 311 is used to protect the visual inspection equipment and prevent it from being damaged by accidental working conditions such as collisions or vibrations. Inside the protective chamber 311 is an observation mirror 310, which is used to block dust from the outside of the visual inspection equipment or liquid splashed during the sampling process.

[0026] The top of the protective chamber 311 is provided with a cleaning ring 303. Sliding rods 309 are fixed on the left and right sides of the cleaning ring 303. Pressing rings 307 are slidably provided on the outer surfaces of the two sliding rods 309. The pressing rings 307 are located above the cleaning ring 303. Multiple cleaning plates 308 are provided between the pressing rings 307 and the cleaning ring 303. The upper and lower sides of the multiple cleaning plates 308 are in contact with the cleaning ring 303 and the pressing ring 307. Multiple electromagnets are provided on the surface of the cleaning ring 303. Multiple magnetic blocks are provided on the side of the pressing ring 307 facing the cleaning ring 303. The multiple electromagnets can generate magnetic force on the multiple magnetic blocks at the same time and control the pressing ring 307 to move along the surface of the adjusting rod towards the cleaning ring 303.

[0027] When the surfaces of the pressing ring 307 and the cleaning ring 303 are in contact with each other, the multiple cleaning plates 308 will be pushed by the pressure ring and gradually tend to be horizontal. The shape of the multiple cleaning plates 308 is adapted to the groove area at the top of the protective chamber 311. When the multiple cleaning plates are in a horizontal state, the surfaces of the multiple cleaning plates 308 can contact the top edge area of ​​the protective chamber 311. At this time, the circumferential drive device 302 in the cleaning ring 303 drives the cleaning ring 303 and the pressing ring 307 to rotate synchronously. In this way, the multiple cleaning plates 308 in the horizontal state can clean the surface impurities and dust in the top area of ​​the protective chamber 311. The circumferential drive device 302 is a belt drive structure, and the circumferential drive device 302 is an electric motor or other equipment.

[0028] In use, first, hold the handle housing 102 and use the multiple curved surfaces on the handle housing 102 to increase the friction between the operator's palm and the surface of the handle housing 102, making it less likely to fall off during sampling. Then, turn on the controller on the handle housing 102 and turn on the detection mechanism 3 to observe the lesions on the patient's surface. After the detection mechanism 3 is started, it uses a visual detection device in conjunction with the electronic LCD screen 106 on the protective housing 101 to detect the condition of the patient's lesions. According to the condition of the patient's lesions, the cutting mechanism 2 is adjusted to adjust different lesion areas. The specific adjustment process is as follows: the first push rod 207 drives the cutting chamber 201 to move linearly on the surface of the sliding tube 203, which can control the distance between the baffle 204 and the cutting blade 206 and the patient's lesion area. Then, the micro motor 105 is used in conjunction with the pulley to drive the limiting ring 208, which can control the limiting ring 208 to rotate along the surface of the protective housing 101, thereby controlling the cutting chamber 201 to rotate along the surface of the sliding tube 203, thereby adjusting the sampling angle of the cutting blade 206.

[0029] Subsequently, the second push rod 205 is extended and multiple cutting blades 206 are driven to move towards the central area of ​​the cutting chamber 201. In this way, multiple cutting blades 206 are used to cut and sample the surface of the patient's eczema lesions. During the process, the integrity of the sample after removal can be observed in real time through the electronic LCD screen 106. If the obtained skin tissue sample is found to be incomplete and does not meet the detection standard, the cutting mechanism 2 can be used to resample the patient's eczema lesions.

[0030] Although multiple second pushers 205 and multiple cutting blades 206 can sample skin tissue from the eczema lesions, the resulting appearance varies depending on the severity of each patient's eczema. For example: Firstly, during an acute eczema flare-up, erythema, papules, and vesicles often appear at the lesion site; after the vesicles rupture, serous exudate is released. Secondly, when eczema is in a subacute or chronic stage, desquamation occurs on the skin surface. These scales are mostly white or grayish-white, dry, thin, and appear in flakes or powder. Thirdly, if the eczema exudate dries, it will form a crust on the skin surface. Therefore, the sampling method needs further adjustment, and the adjustment steps are as follows: The two sets of cutting blades 206 in the two baffles 204 are respectively labeled as S1, S2, S3 and S4.

[0031] If, through the interaction of the electronic LCD screen 106 and the visual detection device, it is observed that the eczema lesion area is in an acute flare-up, then the S1 and S4 cutting blades 206 are extended using the second push rod 205. This allows the two cutting blades 206 to move towards the central area of ​​the cutting chamber 201. The serous exudate near the patient's lesion area is then collected and scraped above the S1 and S4 cutting blades 206. At this time, the S3 and S2 cutting blades 206 remain in their initial state, thus forming a receiving tank capable of holding a small amount of serous exudate (see details...). Figure 8 Then, in conjunction with the visual inspection equipment and the electronic LCD screen 106, the removed sample specimen is observed and then taken out for testing. The cooperation of multiple cutting blades 206 forms a receiving groove, which can prevent the liquid sample from escaping or flowing out from between the cutting blades 206.

[0032] If, through the coordination of the electronic LCD screen 106 and the visual detection device, it is observed that the eczema lesion area is in a subacute or chronic stage, the cutting blades 206 of the two baffles 204, S1, S2, S3, and S4, are simultaneously extended in conjunction with multiple second push rods 205. This causes the cutting blades 206 to move synchronously towards the central area of ​​the cutting chamber 201. This allows fragmented or powdery sample specimens from the patient's lesion area to be scraped off and compressed into the contact area between S1 and S2, and S3 and S4, thereby clamping and fixing the sheet-like or powdery skin tissue (see details). Figure 9 This is to prevent the material from falling off or escaping during subsequent testing.

[0033] If, through the coordination of the electronic LCD screen 106 and the visual detection device, it is observed that the eczema lesion area is in a state where the eczema exudate has dried and a scab has formed on the skin surface, then the S1 and S4 cutting blades 206 are controlled to move towards the central area of ​​the cutting chamber 201 using the second push rod 205, and the S1 and S4 cutting blades 206 are used to scrape away the scab at the patient's lesion. Subsequently, the S2 and S3 cutting blades 206 are controlled to move towards the central area of ​​the cutting chamber 201 through the extension of the second push rod 205. When the S2 and S3 cutting blades 206 come into contact with each other, the second push rod 205 is immediately stopped, so that the S2 and S3 cutting blades 206 only clamp the upper part of the scab. Then, the S1 and S4 cutting blades 206 are controlled in conjunction with the second push rod 205 to treat the patient's lesion. The scab at the lesion site is cut further, and after the cutting is completed, the S1 and S4 cutting blades 206 are controlled to contact each other with the second push rod 205. Then, the second push rod 205 controls the S2 and S3 cutting blades 206 to move away from each other and return to their initial positions. In this way, the scab between the S2 and S3 cutting blades 206 will fall directly above the S1 and S4 cutting blades 206. This not only fixes the top of the scab, but also prevents the skin tissue at the bottom of the scab from being offset in any direction after it is removed, thus avoiding overlap, which would increase the difficulty of cutting and reduce the patient's comfort during the cutting process. At the same time, it can also preserve the cut scab completely on the surface of the S1 and S4 cutting blades 206, which makes it easier to test the removed scab later.

[0034] In addition, during the sampling process of patients with eczema, impurities in the air and eczema fluid ejected from the patient's skin lesions during the sampling process may splash or fall onto the end of the protective chamber 311. Because the protective end near the visual inspection device is designed with a conical structure, it can prevent some dust or impurities from directly floating and adhering to the surface of the observation mirror 310. However, dust in the air or fluid ejected from the patient's skin lesions during the sampling process may accumulate at the edge of the protective chamber 311 near the observation mirror 310, thus affecting the observation efficiency of the visual inspection device and the electronic LCD screen 106. The cleaning ring 303 and the pressing ring 307 are driven by the circumferential drive device 302, causing the cleaning ring 303 and the pressing ring 307 to move together. 7. The device rotates along the top of the protective chamber 311, and then uses an electromagnet to generate a magnetic attraction force on the magnetic block on the pressing ring 307, thereby causing the pressing ring 307 to move towards the cleaning ring 303. During the movement, the pressing ring 307 is always limited by the surface of the adjusting rod, so there will be no displacement or deviation. Secondly, as the pressing ring 307 moves towards the cleaning ring 303, the multiple cleaning plates 308 will gradually approach a horizontal state under the pressure of the pressing ring 307. In this way, the surface of the cleaning plates 308 will completely fit with the top area of ​​the protective chamber 311, and together with the circumferential drive device 302, the edge area of ​​the top of the protective chamber 311 near the observation mirror 310 will be cleaned.
