Description

Technical Field

[0001] The utility model relates to the technical field of the fixing structure of an indwelling venous catheter, in particular to a K-shaped fixing structure. Background Technique

[0002] An indwelling venous catheter, also known as a catheter or vascular access, is a medical device used to establish a venous access in a patient's body for medical operations such as intravenous infusion, blood transfusion, injection of drugs, or monitoring of physiological parameters. An indwelling venous catheter usually consists of a soft catheter inserted into the patient's vein, with one end connected to a fluid bag or a drug syringe and the other end remaining inside the patient's body for operation. The selection of an indwelling venous catheter depends on specific medical needs and the patient's condition. Common types include peripheral indwelling venous catheters (usually inserted in the arm or the back of the hand), central indwelling venous catheters (inserted in the neck or chest veins), arterial indwelling catheters (used for arterial blood sampling or blood pressure monitoring), etc. The use of an indwelling venous catheter requires professional training and strict operating procedures to ensure safety and effectiveness. The fixing structure of an indwelling venous catheter usually refers to a fixing band or transparent adhesive tape used to fix the indwelling venous catheter to the patient's skin to ensure the stability and safety of the venous access.

[0003] In a medical environment, a common method for fixing an indwelling catheter is to use transparent adhesive tape or a special fixing band to fix the indwelling venous catheter to the patient's skin. However, this method does not fix the indwelling catheter very firmly. The fixing strength of the tape may not be sufficient to maintain the position of the indwelling venous catheter stable for a long time, resulting in the displacement or detachment of the indwelling catheter, affecting the reliability of the venous access. Moreover, the repeated winding of the tape has a large contact area with the patient's skin, which is likely to cause skin allergies or even injuries to the patient. Therefore, the utility model provides a K-shaped fixing structure to solve the problems raised in the above background technique. Content of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages existing in the prior art and propose a K-shaped fixing structure. The indwelling catheter is fixedly connected to the connector through a rubber ring, and the magic tape is used to fix the skin tube to prevent backflow and dripping. The connector is firmly fixed to prevent loosening. The cross tape firmly fixes the connector to avoid detachment. The fixing band avoids pressing the skin, prolongs the service life, and improves the fixing effect of the indwelling venous catheter.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A K-shaped fixing structure includes a fixing band and an indwelling needle. The fixing band includes a square band. An L-shaped band is fixedly arranged at the upper end of the square band. A hook surface of a magic tape is fixedly arranged at the front end of the L-shaped band, and a loop surface of the magic tape is fixedly arranged at the rear end of the L-shaped band. Extension bands are fixedly arranged on both sides near the lower end of the square band. Adhesive tapes are pasted on the rear sides of the two extension bands. A rubber ring is fixedly arranged at the lower part near the front end of the square band;

[0007] The indwelling needle includes a connector. An infusion tube is fixedly arranged at the lower end of the connector, and a needle is fixedly arranged at one end of the infusion tube;

[0008] Through the above technical solution, the structure fixes the connector of the indwelling needle by inserting it into the rubber ring, uses the magic tape to fix the rubber tube to prevent kinking and dripping, firmly fixes the connector to avoid loosening, and the cross-fixing adhesive on the extension band enhances the stability of the connector to prevent falling off. The fixing band avoids pressing the skin. This design significantly improves the fixing effect of the venous indwelling needle, and the structure is durable and reusable, extending the service life.

[0009] Further, the square band includes an antibacterial layer. A reinforcing layer is fixedly arranged at the upper end of the antibacterial layer, and a wear-resistant layer is fixedly arranged at the upper end of the reinforcing layer;

[0010] Through the above technical solution, using the antibacterial layer can effectively prevent the growth of bacteria, fungi and viruses, thereby reducing the risk of infection. By setting the reinforcing layer, the durability and wear resistance of the fixing band can be enhanced, and the service life can be extended. The wear-resistant layer provides additional surface protection, reducing the possibility of damage due to friction of the fixing band and maintaining the integrity of its function and appearance.

[0011] Further, the connector is arranged on the front side of the square band, and the connector penetrates through the rubber ring;

[0012] Through the above technical solution, by arranging the connector at the front end of the square band and fixing it through the rubber ring, the indwelling needle is fixed more securely.

[0013] Further, the L-shaped band and the two extension bands are opened to form a K shape;

[0014] Through the above technical solution, by setting the structure in a K shape, the indwelling needle can be fixed more securely, avoiding the falling off of the infusion rubber tube,

[0015] Further, the antibacterial layer is set as a silver ion antibacterial agent;

[0016] Through the above technical solution, the silver ion antibacterial agent is a chemical substance that uses the antibacterial properties of silver ions to inhibit the growth of microorganisms. Silver ions can effectively destroy the cell membrane structure of bacteria, fungi and viruses, thereby achieving the effect of inhibiting and killing these microorganisms.

[0017] Furthermore, the reinforcing layer is set as a thermoplastic polyurethane coating;

[0018] Through the above technical solution, the thermoplastic polyurethane coating can increase the strength of the fixing band, and also has good elasticity and softness, making it more comfortable to use.

[0019] Furthermore, the wear-resistant layer is set as polytetrafluoroethylene;

[0020] Through the above technical solution, it has good wear resistance and can improve the service life of this structure.

[0021] The utility model has the following beneficial effects:

[0022] A K-shaped fixing structure proposed by the utility model fixes the connecting head of the indwelling needle by inserting it into the rubber ring. The one-word band can be folded and pasted through the magic tape to fix the leather tube, which can prevent the leather tube from being folded back and causing the liquid not to drip, and can also fix the connecting head to avoid the joint from loosening. The two tapes pasted on the extension band can be cross-fixed on the connecting head, making the connection head more securely fixed and avoiding falling off. The contact area with the patient's skin is small and does not hurt the skin. By setting the fixing band to block the connecting head, it can avoid the connecting head from pressing on the skin, and has a better fixing effect on the venous indwelling needle, and the service life of this structure is longer and it can be reused.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment

[0032] Refer to Figures 1-5 As shown in the figure, an embodiment provided by the present invention: a K-shaped fixing structure includes a fixing band 1 and an indwelling needle 2. The fixing band 1 includes a square band 101. An L-shaped band 102 is fixedly arranged at the upper end of the square band 101. A hook surface 105 of a magic tape is fixedly arranged at the front end of the L-shaped band 102, and a loop surface 106 of the magic tape is fixedly arranged at the rear end of the L-shaped band 102. Extension bands 103 are fixedly arranged on both sides near the lower end of the square band 101. Adhesive tapes 104 are pasted on the rear sides of the two extension bands 103. A rubber ring 107 is fixedly arranged at the lower part near the front end of the square band 101. The indwelling needle 2 includes a connection head 201. An infusion tube 202 is fixedly arranged at the lower end of the connection head 201. A needle 203 is fixedly arranged at one end of the infusion tube 202.

[0033] By setting the fixing band 1 into three parts: a square band 101, an L-shaped band 102 and two extension bands 103, a K shape is formed when the fixing band 1 is opened, and a "zhi" shape is formed when the L-shaped band 102 is folded and pasted. When fixing the indwelling needle 2, the L-shaped band 102 can be used to fix the leather tube, and the hook surface 105 and the loop surface 106 of the magic tape are respectively arranged at the front and rear of the L-shaped band 102 for pasting, which is convenient for repeated use. By setting the adhesive tape 104 to stick on the extension band 103, it can be replaced after the adhesive tape 104 loses its adhesiveness, which is convenient for long-term use and repeated use. By setting the rubber ring 107, since the rubber ring 107 has a certain elasticity, the connection head 201 can be fixed.

[0034] It should be noted that there may be some inaccuracies in the translation due to the lack of clear and complete original figure reference in the text. You can adjust it according to the actual situation.The square band 101 includes an antibacterial layer 10101. At the upper end of the antibacterial layer 10101, a reinforcement layer 10102 is fixedly arranged. At the upper end of the reinforcement layer 10102, a wear-resistant layer 10103 is fixedly arranged. The use of the antibacterial layer 10101 can effectively prevent the growth of bacteria, fungi and viruses, thereby reducing the risk of infection. By setting the reinforcement layer 10102, the durability and wear resistance of the fixing band 1 can be enhanced, and the service life can be extended. The wear-resistant layer 10103 is provided to provide additional surface protection, reducing the possibility of damage due to friction of the fixing band 1 and maintaining the integrity of its function and appearance. The connector 201 is arranged on the front side of the square band 101. The connector 201 penetrates through the rubber ring 107. By arranging the connector 201 at the front end of the square band 101 and fixing it through the rubber ring 107, the indwelling needle 2 can be fixed more securely. The one-piece band 102 and the two extension bands 103 are opened to form a "K" shape. By setting this structure as a "K" shape, the indwelling needle 2 can be fixed more securely, avoiding the shedding of the infusion tube. The antibacterial layer 10101 is set as a silver ion antibacterial agent. The silver ion antibacterial agent is a chemical substance that uses the antibacterial properties of silver ions to inhibit the growth of microorganisms. Silver ions can effectively damage the cell membrane structures of bacteria, fungi and viruses, thereby achieving the effect of inhibiting and killing these microorganisms. The reinforcement layer 10102 is set as a thermoplastic polyurethane coating. The thermoplastic polyurethane coating can increase the strength of the fixing band 1 and also has good elasticity and softness, making it more comfortable to use. The wear-resistant layer 10103 is set as polytetrafluoroethylene, which has good wear resistance and can improve the service life of this structure.

[0035] Working principle: When the fixing band 1 is in use, the connector 201 of the indwelling needle 2 is inserted into the rubber ring 107 for fixation. The one-piece band 102 can be folded and pasted through the magic tape to fix the tube. It can prevent the tube from being folded back and causing the liquid to stop dripping, and can also fix the connector 201 to avoid the loosening of the connector. The two tapes 104 pasted on the extension bands 103 can be crossed and fixed on the connector 201, which can make the connector 201 fixed more securely. By setting the tape 104 to stick on the extension band 103, the tape 104 can be replaced after it loses its adhesiveness, facilitating long-term use and reuse.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
