Description

Technical Field

[0001] The utility model relates to the technical field of skin scratch examination, in particular to a novel auxiliary skin scratch examination tool. Background Art

[0002] Skin scratches, also known as artificial urticaria, are allergic reactions of the skin blood vessels. The formation of allergic reactions is caused by the combined action of internal and external factors. There is a special protein in the serum of such patients, which is immunoglobulin IgE. If this protein combines with allergens, the body will cause a series of reactions, and finally cause the mast cells around the skin blood vessels to release a large amount of histamine. Histamine will cause the skin blood vessels to dilate, and the serum will leak out of the blood vessels, which will cause itching.

[0003] At present, the examination method of skin scratching is to scratch the skin of the flexor side of the forearm with a blunt instrument. If a wheal is produced at the place where the blunt instrument is scratched after 1-2 minutes, the skin scratch sign is positive. If the skin is suspected to be allergic to a certain allergen, a specific skin scratch test can also be performed. The existing skin scratching examination tools are not convenient for cleaning and disinfecting the patient's skin before testing, cross infection is easy to occur during use, and it is not convenient to calculate the experimental observation time, which is very inconvenient to use.

[0027] like Figure 1-Figure 4 As shown, the embodiment of the utility model provides a novel auxiliary inspection tool for skin scratches, including a handle 100 and a blunt head 200.

[0028] An alcohol storage bin 110 is provided at one side of the rear end of the handle 100 , and an alcohol spray head 300 capable of spraying the alcohol stored in the alcohol storage bin 110 is provided at the rear end of the handle 100 .

[0029] Reference Figure 2 The alcohol spray nozzle 300 is specifically a push-type spray nozzle. The input end of the alcohol spray nozzle 300 is connected to a pipette 310 extending into the alcohol storage bin 110. The push-type spray nozzle belongs to a well-known technology. The alcohol in the alcohol storage bin 110 can be sprayed out by pressing. When in use, the sprayed alcohol spray can be sprayed on the patient's skin to clean and disinfect the skin for skin scratch examination.

[0030] An end cap 320 is provided at the tail end of the handle 100, and the end cap 320 is threadedly sleeved on the tail end of the handle 100. The alcohol nozzle 300 is installed on the end cap 320. After the alcohol in the handle 100 is used up, the end cap 320 can be unscrewed from the tail end of the handle 100, and alcohol can be added to the alcohol storage tank 110, and then the end cap 320 is covered to complete the alcohol replenishment.

[0031] A timing device 400 is provided on the handle 100, and the timing device 400 is used to time the skin scratches during the detection and observation. The timing device 400 in this embodiment adopts electronic timing. Specifically, the timing device 400 includes a timing circuit board 410 and a battery 420 for powering the timing circuit board 410. A battery compartment 130 is provided in the handle 100, and a window 140 is provided on the side wall of the battery compartment 130. The timing circuit board 410 is installed at the window 140. A display screen 411 and a control button 412 are provided on the outside of the timing circuit board 410. The battery 420 is arranged in the battery compartment 130. The timing device 400 can time multiple patients at the same time, and the timing can be set and viewed through the control button 412.

[0032] A joint 120 is provided at the head end of the handle 100 , and the blunt head 200 is detachably mounted on the joint 120 .

[0033] Reference Figure 3 and Figure 4 , a socket 121 is axially arranged on the connector 120, and one end of the blunt head 200 is inserted and installed in the socket 121. The connector 120 is provided with a locking mechanism for locking the blunt head 200 on the connector 120. Specifically, the locking mechanism includes two claws 500, an annular groove 210 is arranged outside the end of the blunt head 200 inserted into the socket 121, and mounting grooves 122 are symmetrically arranged on both sides of the connector 120. The parts of the two mounting grooves 122 located outside the socket 121 are connected with the socket 121, and a transverse through groove 123 is arranged between the two mounting grooves 122 at one end close to the handle 100. The middle parts of the two claws 500 are respectively hinged in the corresponding mounting grooves 122, and one end of the two claws 500 is provided with a limiting protrusion 510 that is stuck in the annular groove 210 on the blunt head 200, and a bow-shaped spring piece 520 placed in the transverse through groove 123 is supported between the other ends of the two claws 500.

[0034] The blunt tip 200 is designed to be detachable. When in use, the blunt tip 200 is inserted into the socket 121 on the connector 120, and the limiting protrusions 510 on the two claws 500 are clamped in the annular clamping groove 210 outside the blunt tip 200 (such as Figure 3As shown in the figure, the blunt tip 200 can be locked in the socket 121 to achieve fixed installation of the blunt tip 200. After using the blunt tip 200, the blunt tip 200 is pointed downward and aligned with the collection box, and the claws 500 on both sides are pressed toward the middle by fingers, so that the limiting protrusions 510 on the two claws 500 are withdrawn from the annular groove 210 outside the blunt tip 200 (as shown in the figure). Figure 4 As shown in the figure, the blunt tip 200 can fall into the collection box under the action of its own weight, so that the blunt tip 200 can be disassembled. There is no need to touch the blunt tip 200 during disassembly, which can prevent medical staff from being exposed to infection.

[0035] In this embodiment, when testing for skin scratches, the skin on the outer side of the upper arm or the back is selected. After disinfecting the skin, a 0.5-1 cm long streak is scratched on the skin with a blunt 200 needle tip, and the scratches should be 4-5 cm apart until there is no bleeding. A control must be used during the test. The results are usually observed 10 minutes after the test, and the test object is wiped off and washed.

[0036] The present application integrates alcohol disinfection on the handle 100, which is convenient for cleaning and disinfecting the patient's skin before testing; the blunt head 200 at the head end of the handle 100 is replaceable, and each patient has a blunt head 200 to prevent cross infection. The blunt head 200 causes little damage to the patient's skin, is replaceable, and is uniformly recycled through medical waste; during the scratch observation process, the timing device 400 can be used to ensure the accuracy of the experimental observation time. The timing device 400 can time multiple patients at the same time, thereby improving the work efficiency of the outpatient clinic; the tool is small and portable, suitable for use in a variety of medical environment scenarios such as skin clinics / emergency rooms, wards, treatment rooms, etc., and has the advantages of diverse functions and easy use.
