Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a novel sterilization cap for an infusion connector. Background Art

[0002] The infusion connector is an important component of the indwelling vascular access infusion system. The heparin cap is the earliest and simplest "needle-mounted infusion connector", mainly composed of a latex stopper, a shrink film and an end cap. The heparin cap is a device used in conjunction with the arteriovenous indwelling needle. It contains heparin components inside, and its main function is anticoagulation. By injecting anticoagulants such as sodium heparin, the heparin cap can prevent blood reflux and coagulation, thereby extending the use time of the intravenous needle, reducing patients' medical expenses, and improving clinical work efficiency.

[0003] At the same time, in order to reduce the occurrence of infusion-related complications, needle-free connectors are now widely used. They are mainly used to connect the vascular catheter port with infusion sets, syringes and other drug delivery devices for drug delivery, or as a protective device for the vascular catheter port during treatment intervals. The two ends of the needle-free connector are called the male Luer port and the female Luer port. The male Luer port is connected to the vascular catheter port, and the female Luer port is connected to the infusion set or syringe and other drug delivery devices.

[0004] Needle-free infusion connectors and heparin caps are commonly used consumables, with significant daily usage in clinical practice. Disinfection of these connectors can be time-consuming, requiring mechanical wiping and disinfection of the connector's cross-section and periphery before each connection. Incomplete disinfection can occur during the connection process due to negligence on the part of healthcare professionals. Studies have shown that 65% of catheter-related bloodstream infections originate from the skin, 30% from contaminated infusion lines, and 5% from other sources. Therefore, the level of connector management is closely linked to the incidence of complications.

[0005] At present, the structure of the disinfection cap for infusion connectors is generally as described in the infusion connector disinfection cap disclosed in the patent application number "CN202321478989.8", which includes a disinfection component, on which the infusion connector is screwed; the disinfection component includes an outer shell, anti-slip ribs, an inner conical thread, a cavity, a support column, barbs, a cotton pad, an end face boss and a sealing film, the interior of the outer shell is provided with an inner conical thread, the interior of the outer shell is provided with a cavity, a number of support columns are provided at one end of the inner shell, a cotton pad is placed inside the cavity, an end face boss is provided at one end of the outer shell, and a sealing film is adhered to the outside of the end face boss. However, the disinfection cap of this utility model is connected by threaded fitting and cannot be used for connector consumables without external threads, making it inconvenient to disinfect infusion connectors without external threads.
