Description

Technical Field

[0001] This utility model relates to a sampler, specifically a special sampler for extracting a mixture of dry ice and acetone for the treatment of skin diseases, belonging to the technical field of skin disease treatment devices. Background Technology

[0002] Generally speaking, with the continuous advancement of medical technology, the demand for cryotherapy in the field of skin disease treatment is also increasing. Dry ice, as a highly efficient coolant, acts on local tissues, causing a series of physicochemical changes that lead to tissue cell degeneration and necrosis, thus achieving a therapeutic goal. This method is widely used in skin treatment.

[0003] Currently, there are no small, portable extraction devices suitable for the treatment of skin diseases on the market. Medical personnel use medical cotton swabs as extraction devices for dry ice and acetone mixtures during the treatment of skin diseases.

[0004] The existing homemade extraction device has the following shortcomings: 1. Insufficient strength and stability: Medical cotton swabs are usually made of lightweight materials, which may not be able to withstand the weight or temperature changes of the dry ice and acetone mixture, and are prone to breakage or deformation; 2. Poor temperature resistance: The temperature of dry ice is very low, about -78.5℃, and the material of the cotton swab may not be able to withstand such an extremely low temperature, which may lead to embrittlement or cracking; 3. Chemical compatibility issues: Acetone is an organic solvent, which may corrode or degrade the material of the cotton swab, affecting the extraction effect and the integrity of the device; 4. Low extraction efficiency: The design of medical cotton swabs is not suitable for chemical extraction processes, and may not be able to mix effectively with the sample, thereby reducing the extraction efficiency; 5. Operational safety hazards: Using inappropriate materials may lead to safety hazards, such as material breakage or improper chemical reactions, which may cause injury to the operator; 6. Cleaning and sterilization issues: Medical cotton swabs need to be cleaned and sterilized before reuse, but their surface structure may not be conducive to thorough cleaning, posing a risk of cross-contamination; 7. There is a lack of relevant graduation markings when extracting dry ice and acetone mixtures, and medical personnel can only extract the mixture based on personal experience. Therefore, it can be concluded that using medical cotton swabs as a device for extracting dry ice and acetone mixtures is not the best choice.

[0005] Therefore, the key to solving the above technical problems lies in developing a special sampler that is simple to operate, safe and reliable for the extraction of icy acetone mixtures. Summary of the Invention

[0062] In this utility model, the fixing tube 12 is made of hospital adhesive tape. The function of the fixing tube 12 is to limit the push rod 21 and prevent the push rod 21 from sliding out of the groove of the connecting tube.

[0063] Specifically, such as Figure 3 As shown, the connector 13 has an overall cylindrical structure, and the outer side of the connector 13 is provided with an external thread section.

[0064] Specifically, such as Figure 3 As shown, the sampling port 111 is inclined at the end; the scale 112 is arranged along the outer side of the end of the sampling port 111 towards the connector 13.

[0065] Furthermore, such as Figure 2 As shown, the ejection mechanism 2 includes:

[0066] Push rod 21 is slidably connected in sampling slot 11;

[0067] Push block 22, push block 22 is connected to the outer side of one end of push rod 21;

[0068] Among them, push block 22 is located at the end of connector 13.

[0069] In this utility model, the push rod 21 is made of bamboo and wood, and its function is to push the mixture 4 in the sampling groove 11 out of the groove; the push block 22 is made of bamboo and wood, and its function is to provide a point of force for the finger, so that the finger's pushing force can be easily transmitted to the push rod 21.

[0070] Specifically, such as Figure 2 As shown, the push rod 21 has a cylindrical structure, and the diameter of the push rod 21 is adapted to the inner diameter of the sampling groove 11 and the fixing tube 12.

[0076] Before use, the special sampler for extracting a mixture of dry ice and acetone for the treatment of skin diseases with the above-mentioned design structure needs to be installed as a backup.

[0077] The specific assembly steps are as follows: First, thread the connector 13 of the sampling component 1 into the internal threaded connection hole in the middle of the front end of the sampling handle 3.

[0078] Then, connect the upper part of one end of the push rod 21 to the lower part of the push block 22 by adhesive bonding, so that the push block 22 is located at the end of the sampling handle 3;

[0079] Finally, the fixing tube 12 is installed in the middle of the sampling tank 11, so that the inner wall of the bottom of the fixing tube 12 is connected to the outer wall of the bottom of the sampling tank 11. The connection method is to use glue or to process it into a whole. After processing and installation, it can be used.

[0080] The specific steps for using it are:

[0081] Before use: 1. Study the procedures; Because the use of the sampler must follow a strict standard operating procedure to ensure the correct use and safety performance of the equipment, the operating procedure must be studied and understood again before using the sampler; 2. Pre-operation preparation: Take the sampler out of the dedicated instrument and equipment case, check whether the appearance of the sampler is intact, whether there is obvious damage or deformation of each part, and ensure that the inside of the sampler is dry and free of moisture or impurities before use.

[0082] When using it, medical staff should first open the storage device 5 used to store the dry ice-acetone mixture 4;

[0083] Then, the medical staff inserted the sampling port 111 at the front end of the sampling slot 11 into the prepared dry ice-acetone mixture 4.

[0084] Immediately afterwards, the medical staff rotated the sampling handle 3 and tilted the sampling slot 11 to remove it from the mixture 4. At this time, the extracted therapeutic dry ice acetone mixture 4 was stored in the sampling slot 11 at the top of the push rod 21.

[0085] Finally, the dry ice-acetone mixture 4 can be used to treat skin diseases. By pushing the pusher 22 with your finger, the pusher 21 moves forward in the sampling groove 11. The movement of the pusher 21 pushes the mixture 4 in the sampling groove 11 onto the skin lesion, thus completing the extraction of the dry ice-acetone mixture 4.

[0086] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way.
