Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a reusable press needle removal device. Background Technology

[0002] Acupuncture has a special therapeutic effect on sub-health conditions, as it can unblock meridians, harmonize yin and yang, and strengthen the body's resistance while eliminating pathogenic factors. Press needles, as a type of acupuncture, are epidermal needles compared to the subcutaneous needling method of traditional acupuncture. They act as acupoint massage, immediately improving clinical symptoms and achieving the effect of continuous acupuncture treatment, resulting in immediate therapeutic effects.

[0003] A press needle is a thumbtack-shaped needle with a flat handle and a length of about one to two fen (approximately 0.5-0.6 cm). It is commonly used for intradermal needles or ear needles. Press needles are usually removed by tearing them off with hemostatic forceps or by rubbing the edges of the adhesive with a damp cotton swab to make them curl up and peel off. In daily use, it is also common to use fingernails to pry off the edges of the press needle adhesive, which can easily injure the patient's skin. Because the adhesive is difficult to remove, it is very time-consuming.

[0004] Several patents for press needle removal are disclosed in the prior art. Among them, utility model patent CN116270215A discloses a press needle removal device, including a first clamp arm, a second clamp arm, and two ring-shaped handles connected to the bottom ends of the first and second clamp arms. The first and second clamp arms are connected by a through-type hinge shaft. Limiting stops are provided on the inner side of the bottom end of the first and second clamp arms. Arc-shaped arms are fixedly connected to the top ends of the first and second clamp arms. A first needle removal head and a second needle removal head are fixedly connected to the top end of each arc-shaped arm. Several needle removal anti-sticking strips are fixedly provided on the inner side of the first and second needle removal heads near the front end. Although this solves the problem of tape sticking to hands and being difficult to throw away during press needle removal, and tape sticking to tweezers and being inconvenient to dispose of in the sharps box, the problems of easily injuring the patient's skin during press needle removal, time-consuming removal, and the inconvenience of operation due to the limited functionality of the removal tool still exist.

[0005] In view of this, the inventors conducted in-depth research to address this need, which led to this case. Utility Model Content

[0006] To overcome the problems of easy skin injury during press needle removal, time-consuming operation, and inconvenient operation due to the limited functionality of existing removal tools, this utility model provides a reusable press needle removal device, including a rectangular housing, a scraper, and a clamping device. Either end of the housing is horizontally rotatably connected to the tail of the clamping device and the tail of the scraper via a pin. The housing has a through-hole along its length, within which the clamping device and the scraper can be placed. A storage box is provided at the end of the housing opposite to the pin.

[0007] The device employs a design with a storage space extending through the middle of the housing. The scraper and clamping device are fixed to the middle of the two layers of the storage space using a pin. This facilitates easy rotation of the required components during use and makes it easy to store them after use. Additionally, a storage box is provided at the end of the housing away from the pin for placing items such as solvent cotton pads for easy access by medical personnel. Overall, needle removal is convenient and safe, and the adhesive does not easily stick to the needle removal tool. The device has a simple structure and low manufacturing cost. Furthermore, stainless steel can be used during production for easy sterilization and reusability.

[0008] Preferably, the clamping device includes two clamping bodies that can move towards each other at least at their front ends. Each clamping body includes a handle and two clamping heads integrally formed with the handle. The two clamping heads are hinged to each other near the middle of the housing, and the end faces of the opposite ends of the two clamping heads are flush.

[0009] With the above technical solution, one end of the clamping device is designed as a flat-headed tweezer, and the middle of the clamping handle of the two clamping bodies is connected to each other, which is equivalent to the elastic deformation connection of the rear end of the existing traditional tweezers that can be reset. The remover is easy to hold and operate, and can be used to clamp adhesive tape as well as remove needles, which can avoid needle pricks and increase the accuracy of operation.

[0010] Preferably, the chuck has an extension near its end, and a finger stop is provided at the edge of the extension. The finger stop extends outward from the chuck and forms a ring with the two opposite edges of the extension.

[0011] Through the above technical solution, the design of the extension section and the finger guard section, on the one hand, increases the contact area between the finger and the needle clamp without widening the clamp handle as much as possible, making the operation more stable; on the other hand, it effectively prevents the clamp from accidentally slipping out of the hand, thus ensuring that medical staff can retrieve the needle securely, conveniently, and without the risk of the needle slipping out. Removal after needle retrieval or adhesive application is also convenient, as the hand never needs to touch the side of the presser with the needle tip, making it safer and also facilitating storage.

[0012] Preferably, the storage box includes a base and a lid that matches the base. The base is integrally connected to the end of the storage shell. The base and the lid are connected on one side by a hinge and on the other side by a snap fastener.

[0013] The above technical solution connects the base to the rear end of the storage shell and matches the lid to the base, making the storage box and storage shell a seamless whole. The base and lid are connected by hinges and buckles on opposite sides for easy use.

[0014] Preferably, the scraper component includes a connecting rod and a scraper that are rotatably connected to the housing. The scraper is integrally connected to the connecting rod, and the scraper and the connecting rod are provided at an angle along the length of the connecting rod. A soft silicone scraper strip is provided at the end of the scraper.

[0015] The above technical solution sets an angle at the connection between the connecting rod and the scraper, which is beneficial for applying external force to the scraper during use. At the same time, in order to avoid causing discomfort to the patient when using the scraper, a soft silicone scraper strip is set at the end of the scraper. When using the scraper, take out the solvent cotton pad from the storage box, wipe around the adhesive patch to make the edges lift up, and then scrape it with the scraper.

[0016] Preferably, the inner side of the clamp opposite to the extension is provided with a plurality of reinforcing ribs, and the side of the extension opposite to each other is provided with a plurality of anti-slip strips.

[0017] The above technical solution provides a reinforcing rib on the inner side of the extension section, which makes the extension section more stable and prevents it from cracking due to excessive force. The two ends of the clamp handle are set with different widths, which makes it easier for the narrower end to connect with the storage shell. At the same time, an anti-slip strip is set on the outer side of the extension section to increase the friction between the fingers and the extension section during use, so that the adhesive can be quickly peeled off from the patient, thus making it easier for medical staff to remove the needle.

[0018] Preferably, the end face and abutment face of the free end of the chuck are provided with a plurality of needle-starting anti-stick strips, and the outer surface of the anti-stick strips and the inner side of the chuck are coated with a metal anti-stick coating.

[0019] The tape on the snap needle can be quickly lifted by the chuck head. The anti-stick strip and metal anti-stick coating on the snap needle head can also prevent the tape from sticking to the device, making needle removal convenient and safe, and the tape will not stick to the chuck head.

[0020] Preferably, the end of the housing near the pin tapers inward, and the anti-stick strip is arranged parallel to the side of the clamp.

[0021] By using the above technical solution, the end of the housing near the pin is gradually tapered inward, which can better constrain the clamp and connecting rod inside the housing, making the demolition device more stable during use and preventing the other part from rotating back and forth while one part is in use, thus affecting the operation.

[0022] Preferably, the width of the scraper is smaller than the width of the receiving shell.

[0023] Preferably, the height of the clamp is less than the height of the accommodating space.

[0024] By using the above technical solution, limiting the width of the scraper and the clamp allows the main components of the scraper and the clamping device to be accommodated in the storage space of the housing, which facilitates the storage and retrieval of the demolition device.

[0025] The beneficial effects of adopting the technical solution of this utility model are as follows:

[0026] (1) The device adopts a method of opening a storage space through the middle of the housing, and fixing the connecting rod and clamp to the two layers of the storage space by means of a pin. It is convenient to rotate out the required parts during use, and it is also convenient to put them away after use. In addition, a storage box is provided at the end of the housing away from the pin, which can be used to put the solvent cotton pads, etc., for easy access by medical staff. Overall, the needle removal is convenient and safe, and the adhesive is not easy to stick to the needle removal tool. The device has a simple structure and low manufacturing cost. In addition, stainless steel material can be selected during production, which is easy to disinfect and can be reused.

[0027] (2) The design of the extension section and the finger guard section increases the contact area between the finger and the needle clamp without widening the clamp handle as much as possible, making the operation more stable. On the other hand, it can effectively prevent the clamp from accidentally slipping out of the hand, thus ensuring that medical staff can retrieve the needle securely, conveniently, and without the needle slipping out of their hands. It is also convenient to remove the needle or remove it after the adhesive is applied, and the hand never needs to touch the side of the presser with the needle tip, which is safer.

[0028] (3) By gradually narrowing the end of the housing near the pin, the clamp and connecting rod can be better constrained in the housing, making the demolition device more stable during use and preventing the other part from rotating back and forth while one part is in use, thus affecting the operation.
