Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary equipment technology, specifically to an indwelling needle fixation device. Background Technology

[0002] The use of indwelling needles can reduce the pain and fear of injections caused by repeated venous punctures in children, alleviate the anxiety of parents, facilitate clinical medication administration, and provide emergency medication for critically ill patients. It also reduces the workload of nurses and reduces the pain of children. Therefore, indwelling needles are widely used in clinical practice. In the current technology, indwelling needles need to be wrapped with adhesive tape. However, long-term use of adhesive tape can cause bruising due to pressure. The material is too hard, and the tape will loosen over time. At the same time, patients will feel uncomfortable when tearing off the tape. In addition, the indwelling needle is exposed and there is no way to cover most of the surface of the indwelling needle for protection. The lack of protective devices makes it easy to accidentally touch the indwelling needle.

[0003] For example, the authorized patent document with application number CN202021863439.4 discloses an indwelling needle, which relates to the field of medical device technology, and aims to solve, to some extent, the technical problem of improper sealing of indwelling needles leading to blockage and thrombosis. The indwelling needle provided by this utility model includes a needle seat, a needle tube, a puncture needle, and a stop; both the needle seat and the puncture needle are hollow, and an infusion channel is formed along the axial direction of the needle tube. The needle tube is located at one end of the needle seat and connected to the needle seat. The puncture needle... The puncture tip passes through the needle hub and the infusion channel in sequence, and partially protrudes from the needle tube; the end of the puncture needle away from the puncture tip protrudes from the needle hub and is provided with a gripping part, which abuts against the edge of the end of the needle hub away from the needle tube; a stop is provided in the infusion channel, and the size of the stop matches the inner diameter of the infusion channel; one end of the stop is rotatably connected to the needle tube, and the other end abuts against the needle body of the puncture needle. When the puncture needle is withdrawn from the needle tube, the stop rotates relative to the needle tube and can block the infusion channel.

[0004] The aforementioned patents fail to adequately shield and protect most of the surface of the indwelling needle, lacking protective devices and making it easy to accidentally touch the indwelling needle. Therefore, we need to provide an indwelling needle fixing device. Utility Model Content

[0030] Specifically, a protective mechanism 2 is installed at the indwelling needle site to provide auxiliary protection and prevent accidental contact. The indwelling needle needs to remain stable in the blood vessel to prevent it from falling out or shifting. The protective cover 4 may include an auxiliary pressing function for the indwelling needle, fixing it in place with appropriate pressure and reducing the possibility of movement.

[0031] The top of the indwelling needle assembly 1 is provided with a protective cover 4, the protective holding mechanism 3 is disposed inside the protective cover 4, and the surface of the protective cover 4 is provided with a fastener 5 for fixing the protective cover 4 to the limb.

[0032] In this embodiment, the indwelling needle assembly 1 is inserted into the patient's limb. The protective cover 4 is placed above the indwelling needle assembly 1 to protect it. The breathable bandage 53 is stretched, and the hook and loop fasteners 51 and 52 are attached to each other to secure the protective cover 4 to the limb. This method is suitable for limbs of different widths. The adjustment rod 32 is rotated by rotating the knob 7. The adjustment rod 32 is threaded onto the sleeve 31, which moves the protective cotton strip 33 down close to the indwelling needle assembly 1. This provides auxiliary pressure on two parts of the indwelling needle assembly 1. The auxiliary pressure function can reduce the stimulation and pressure of the indwelling needle on the blood vessel wall, thereby reducing the patient's discomfort. A spring 303 is provided between the disc and the circular frame 301 to allow the disc to float, further improving the elasticity and fit of the indwelling needle assembly 1. The protective cotton is a sterile cotton strip. Since the circular frame 301 and the adjustment rod 32 are rotatably connected, the circular frame 301 does not need to rotate when the adjustment rod 32 rotates.

[0033] The fastener 5 includes two hook and loop fasteners 51 on one side of the protective cover 4 and two hook and loop fasteners 52 on the other side of the protective cover 4. The hook and loop fasteners 51 and the hook and loop fasteners 52 work together. Both the hook and loop fasteners 51 and the hook and loop fasteners 52 are provided with breathable bandages 53. The tops of the four breathable bandages 53 are all installed on the surface of the protective cover 4. Specifically, when the indwelling needle assembly 1 is inserted into the patient's limb, the protective cover 4 is placed on top of the indwelling needle assembly 1 for protection. The breathable bandages 53 are stretched, and the hook and loop fasteners 51 and the hook and loop fasteners 52 are attached to each other, thus binding the protective cover 4 to the limb and adapting to different limb widths and sizes.

[0034] The protective mechanism 2 includes a protective cover plate 21 hinged to the top of the protective cover 4. An elastic element 20 is provided inside the protective cover plate 21.

One end of the push block 204 passes through one side of the protective cover and extends outward. It is worth noting that by pressing the push block 204, the buckle 203 moves. The buckle 203 moves within the groove 201 and squeezes the two springs 202, causing the buckle 203 to disengage from the slot 22 and achieve the flipping of the protective cover 21.

[0036] Both springs 202 have sliding rods 6 movably sleeved inside them. The surfaces of both sliding rods 6 are movably sleeved inside the buckle 203. Both sliding rods 6 are fixedly installed inside the groove 201. The sliding rods 6 are located inside the groove 201 to enhance the guiding effect on the movement of the buckle 203, and the sliding rods 6 also prevent the springs 202 from bending.

[0037] The protective holding mechanism 3 includes two sleeves 31 embedded in the protective cover plate 21. Each sleeve 31 has an adjusting rod 32 threaded inside. Each adjusting rod 32 has a buffer 30 rotatably mounted at the bottom. Each buffer 30 has a protective cotton strip 33 at the bottom.

[0038] It should be noted that by rotating the knob 7, the adjusting rod 32 is rotated. The adjusting rod 32 is threadedly installed with the sleeve 31, which moves the protective cotton strip 33 down closer to the indwelling needle assembly 1. This provides auxiliary pressure on two points of the indwelling needle assembly 1. The auxiliary pressure function can reduce the stimulation and pressure of the indwelling needle on the blood vessel wall, thereby reducing the patient's discomfort.

The adjustment rod 32 is rotated by turning the knob 7. The adjustment rod 32 is threaded onto the sleeve 31, which moves the protective cotton strip 33 down close to the indwelling needle assembly 1, providing auxiliary pressure at two points. This auxiliary pressure function can reduce the stimulation and pressure of the indwelling needle on the blood vessel wall, thereby reducing the patient's discomfort. A spring 303 is provided between the disc and the circular frame 301 to allow the disc to float, further improving the elasticity and fit of the indwelling needle assembly 1. The protective cotton is a sterile cotton strip. Since the circular frame 301 and the adjustment rod 32 are rotatably connected, the circular frame 301 does not rotate when the adjustment rod 32 rotates.

[0044] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
