Description

Technical Field

[0001] This utility model relates to the field of heparin cap technology, specifically a heparin cap that works in conjunction with a sterilization cap. Background Technology

[0002] Heparin caps are primarily used as key components in intravenous infusion lines, playing a vital role in connecting infusion tubing to medical devices such as indwelling needles. They deliver various medications, nutritional solutions, and saline solutions into the body through the infusion channel, facilitating clinical treatment and nursing care. They allow medical staff to perform multiple infusions, injections, or blood draws without frequent punctures of the patient's veins, effectively reducing patient discomfort and lowering the risk of vascular damage.

[0003] However, heparin caps are highly susceptible to contamination by various bacteria, viruses, and other pathogens during prolonged exposure to the external environment. This contamination can enter the patient's body along the infusion route, causing serious medical complications such as local infections and bloodstream infections. This not only prolongs hospital stays and increases medical costs but can also pose a serious threat to the patient's life and health. To reduce the risk of infection, medical institutions typically employ measures such as regularly replacing heparin caps or disinfecting them. Replacing heparin caps increases medical costs, and the disinfection process before each use is cumbersome and carries the risk of incomplete disinfection and infection.

[0004] Therefore, this invention proposes a heparin cap that works in conjunction with a sterilization cap to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a heparin cap that works in conjunction with a sterilization cap, in order to solve the problems of existing heparin caps being easily contaminated during long-term exposure, having high replacement costs, and having cumbersome and risky sterilization operations.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A heparin cap for use with a sterilization cap includes a heparin cap and a sterilization cap. The heparin cap includes a rubber stopper and a heparin cap body.

[0014] By adopting the above technical solution, the disinfection of heparin caps can be guaranteed, and the residue of disinfectant cotton material can be avoided.

[0015] Furthermore, an elastic sealing gasket is connected to the inner bottom of the disinfection cap, and the elastic sealing gasket is made of silicone.

[0016] By adopting the above technical solution, the elastic sealing gasket can fit tightly against the heparin cap body, forming a good sealing effect and preventing external contaminants from entering; at the same time, it can prevent internal liquid leakage.

[0017] Furthermore, both the heparin cap body and the sterilization cap shell are made of medical-grade polycarbonate.

[0018] By adopting the above technical solutions, the heparin cap body and the sterilization cap shell can withstand the erosion of various medical disinfectants and drugs, ensuring safety in medical applications.

[0019] Furthermore, the heparin cap body is provided with anti-slip protrusions on its periphery.

[0020] By adopting the above technical solution, the heparin cap can be held more securely during operation, thus improving the safety of medical procedures.

[0021] In summary, compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] This invention allows for the separation of the sterile cap from the heparin cap body by rotating it in the reverse direction when a heparin cap is needed for puncture and injection. This exposes the rubber stopper of the heparin cap body for operation. After puncture and injection, the sterile cap is screwed on again until the second puncture and injection, thus avoiding tedious and repetitive sterilization operations, achieving a continuous sterilization effect, providing convenience for clinical treatment and nursing, protecting patients, and reducing the risk of infection.

The rubber stopper 1 is connected to the end of the heparin cap body 2. An external thread 4 is connected to the outer side of the heparin cap body 2, and the axial length of the external thread 4 is 1 / 4 of the circumference of the heparin cap body 2. This allows for a quick and stable connection between the sterilization cap and the heparin cap, saving operation time, improving work efficiency, and is suitable for emergency medical situations. The external thread 4 of the heparin cap body 2 is coated with an antibacterial coating 5. The antibacterial coating 5 is made of nano-silver particles with a particle size between 10-50 nm. The nano-silver particles can effectively inhibit the growth and reproduction of bacteria, significantly reducing the risk of contamination of the heparin cap during use, providing a cleaner interface environment for medical operations, and reducing various complications caused by microbial infection. Anti-slip protrusions 3 are provided on the periphery of the heparin cap body 2. This allows for a more stable grip on the heparin cap during operation, improving the safety of medical procedures.

[0032] The disinfection cap includes a cap shell 6 and a disinfection cotton 11. The cap shell 6 has a placement groove 8 that fits the heparin cap body 2. The cap shell 6 is fitted onto the end of the heparin cap body 2 connected to the rubber stopper 1. The placement groove 8 has a threaded groove 9 corresponding to the external thread 4. Inside the cap shell 6, corresponding to the top of the placement groove 8, there is a disinfection groove 10, in which the disinfection cotton 11 is placed. Inside the cap shell 6, corresponding to the disinfection cotton 11, there is an isolation layer 16, which is made of non-woven fabric. The top of the cap shell 6, corresponding to the disinfection groove 10, has ventilation micropores 12 with a diameter ranging from 0.05 to 0.2 mm. A sealing sticker 13 is connected to the ventilation micropores 12. The ventilation micropores 12 ensure air circulation within the disinfection groove 10, helping to maintain the disinfection activity of the disinfection cotton 11 and extend its disinfection validity period. The sealing sticker 13 can seal the disinfection groove 10 in specific environments, effectively preventing the micropores from entering the disinfection groove 10. The upper end of the sterilization cap shell 6 has a handle groove 14, and the outer surface of the handle groove 14 has anti-slip texture 15. This facilitates medical staff in picking up and rotating the sterilization cap, making it easier to install and remove the heparin cap and improving operational convenience. An elastic sealing gasket 17, made of silicone, is connected to the inner bottom of the sterilization cap. Both the heparin cap body 2 and the sterilization cap shell 6 are made of medical-grade polycarbonate.

[0033] The working process of this utility model is as follows:

[0034] First, hold the hand-held groove 14 on the outer shell 6 of the disinfection cap and align the placement groove 8 of the disinfection cap with the heparin cap body 2, so that the external thread 4 on the heparin cap body 2 begins to engage with the threaded groove 9 in the placement groove 8. As the disinfection cap is screwed in, the elastic sealing gasket 17 contacts the heparin cap body 2 and is gradually compressed to form a tight seal, preventing external contaminants from entering. Then, the rubber stopper 1 on the heparin cap body 2 is located directly below the disinfection groove 10 inside the outer shell 6 of the disinfection cap, and the disinfection cotton 11 in the disinfection groove 10 can disinfect the rubber stopper 1.

[0035] When a heparin cap is needed for puncture and injection, rotate the sterile cap shell in the opposite direction to separate the sterile cap from the heparin cap body 2, thereby exposing the rubber stopper 1 of the heparin cap body 2 for operation. After puncture and injection, screw the sterile cap back on until the second puncture and injection, thus avoiding tedious and repetitive sterilization operations, achieving a continuous sterilization effect, providing convenience for clinical treatment and nursing, protecting patients, and reducing the risk of infection.
