Description

Technical Field

[0001] The utility model relates to the technical field of children's skin, in particular to a children's skin surface sampling device. Background Art

[0002] Common skin diseases in children include urticaria, contact dermatitis, ringworm, eczema and other skin diseases. When diagnosing skin diseases, it is often necessary to sample and test the patient's surface skin (that is, the epidermis of the skin) for diagnosis. At present, hospitals often use scalpels and other knives in combination with tweezers to sample the skin surface. First, a scratch is made on the patient's skin surface at the location where the sample is required by the scalpel, and then the epidermis is clamped at the edge of the scratch with tweezers, and the epidermis is peeled off to complete the sampling. The existing technology of skin sample sampling knives disclosed at present, such as patent publication numbers CN203089211U, CN202526227U, CN202665582U and CN210962077U, all disclose a skin sample sampling knife. The skin surface is scratched and cut by a sampling knife. During use, since the tweezers themselves are relatively sharp, only a small part of the edge of the surface skin can be clamped when clamping the surface skin, and the epidermis can be easily clamped off, so multiple attempts are required to succeed, resulting in this method being cumbersome to operate and time-consuming. For adults, it may be tolerable. Adults have a certain degree of patience and can allow medical staff to perform multiple operations to complete the sampling of the skin surface. However, since children have poor tolerance and are prone to move around due to pain, it is difficult for them to cooperate with medical staff for a long time to adopt the above method to sample their surface skin. Therefore, in combination with the above-mentioned existing surface skin sampling method, a skin surface sampling device that is relatively fast, reduces multiple operations, and is more suitable for children is proposed.

The sampling rod 3 is cylindrical, and the position of the clamping groove 8 is set in the middle position of the sampling rod 3. By setting the clamping groove 8 and the splint 4 in the middle position, the most protruding part of the outer periphery of the sampling rod 3 can just contact the skin, so that the skin can be better clamped, and the outer diameter of the sampling rod 3 is relatively thin, set between 1mm-3mm, so that the skin can be better rolled. When in use, a magnifying glass 9 can also be used in conjunction, or a magnifying glass 9 bracket can be installed on the handle 1. The magnifying glass 9 is installed on the bracket, so that the position of the child's skin surface can be better observed for scratching, cutting and clamping. Please refer to Figure 1 and Figure 7 .

[0044] Correspondingly, the elastic component includes: a sleeve 10, an elastic cavity 11 and a spring 12. The sleeve 10 is rotatably sleeved on the outside of the sampling rod 3, and the bottom of the sleeve 10 is connected to the top of the handle 1. The elastic cavity 11 is arranged on the inner wall of the sleeve 10 to adapt to the active position of the splint 4. A plurality of springs 12 are connected between the splint 4 and the clamping groove 8, and the plurality of springs 12 are concentratedly arranged at the position of the sleeve 10. The elastic cavity 11 can provide a range of motion for the splint 4, so that the splint 4 and the clamping groove 8 can be separated or approached. The spring 12 can push the splint 4 to pop out better and separate from the clamping groove 8.

[0045] Correspondingly, the adjustment component includes: an elastic groove 13, an elastic plate 14, a slide groove 15, a slide plate 16, a slide plate 2 17 and a push plate 18. The elastic groove 13 is arranged in the elastic cavity 11, and the elastic plate 14 is also elastically installed in the elastic groove 13 by a plurality of springs 12. A slide groove 15 is arranged on the sleeve 10 near the elastic cavity 11, and the slide groove 15 is communicated with the elastic groove 13. The slide plate 16 is slidably arranged in the slide groove 15. The top of the slide plate 16 extends upward to form a slide plate 2 17. The thickness of the slide plate 2 17 is less than that of the slide plate 16. The connection between the slide plate 16 and the slide plate 2 17 is arranged in an inclined structure 19. The push plate 18 is connected to the slide plate 16 through a slider, and a strip groove suitable for the sliding of the slider is arranged on the outer wall of the sleeve 10. The slider can be pushed to slide along the strip groove through the push plate 18, thereby pushing the slide plate 16 to slide. Since the thickness of the slide plate 16 is greater than the thickness of the slider When the clamping plate 4 is separated from the clamping groove 8 by the action of the spring 12, the push plate 18 is downward, that is, the slide plate 2 17 is just in the elastic groove 13. The thickness of the slide plate 2 17 is relatively thin and will not affect the movement of the clamping plate 4. When the clamping plate 4 needs to be pushed to the position clamped with the clamping groove 8, the clamping plate 4 is moved upward. Under the action of the inclined structure 19, the thicker slide plate 2 17 enters the elastic groove 13 and pushes the elastic plate 14 to the position of the clamping groove 8, thereby forming a cylindrical shape between the clamping plate 4 and the clamping groove 8 again, wherein the elastic plate 14 is also an arc-shaped plate. When the clamping plate 4 and the sampling rod 3 rotate, they can rotate with them and cooperate with the elastic cavity 11 to form a rotating inner circle for the sampling rod 3. Among them, the interior of the spring 12 is provided with a directional rod 20, which is fixedly connected to the clamping plate 4, and the directional rod 20 is provided with a movable slot on the clamping groove 8 to ensure the use position of the clamping plate 4 and the clamping groove 8.

[0046] It should also be noted that the driving mechanism includes: a motor 21 and a battery 22. An installation cavity is provided inside the handle 1, and the motor 21 is installed in the installation cavity. The output end of the motor 21 is connected to the bottom of the sampling rod 3. A battery cavity is provided at the bottom of the handle 1, and the battery 22 is installed in the battery cavity to provide power to the motor 21. A push switch 23 is installed on the outer wall of the handle 1 to control the rotation of the motor 21, thereby controlling the rotation of the sampling rod 3. The outer wall of the sampling rod 3 and the outer wall of the splint 4 are also provided with anti-slip textures.

[0047] Embodiment 2, in order to improve the acceptance of the sampling device by children, further comprises a protective cover 24, which is mounted on the outside of the sampling rod 3 and has a lollipop-shaped structure, see Figure 7 , and cute patterns are pasted on the outside of the handle 1 and the protective cover 24 to make it easier for children to accept.

[0048] To sum up, when using the children's skin surface sampling device, first take out the disinfected sampling device, then find the position on the child's skin surface where sampling is required, open the protective cover 24, cooperate with the magnifying glass 9, and use the knife head 2 to scratch and cut on its surface. After completion, slide the push plate 18 downward to separate the clamping plate 4 and the clamping groove 8, observe the position between the clamping plate 4 and the clamping groove 8 through the magnifying glass 9, align it with the scratch and cut position, and then push the push plate 18 upward to make the clamping plate 4 and the clamping groove 8 clamp the edge of the surface skin, turn on the motor 21, and make the sampling rod 3 rotate slowly, so that the surface skin is removed by winding, so as to achieve the purpose of sampling. When it is necessary to detect and observe the surface skin, make it stick to the glass slide, then rotate the motor 21 in the opposite direction, and release the clamping plate 4, spread the surface skin flat on the glass slide, and finally place it on a microscope or other detection equipment for detection.
