Description

Technical Field

[0001] The utility model relates to the technical field related to medical instruments, in particular to a disposable infusion connector disinfection cap. Background Art

[0002] Patients who are hospitalized for a long time and receive intravenous infusion usually use intravenous catheters for infusion to avoid repeated punctures. The infusion connectors connected to these catheter connectors are exposed to the outside for a long time, which can easily cause infusion infection. In order to avoid infection, the infusion connectors are usually disinfected with disposable disinfection caps.

[0003] Chinese patent CN204563304U discloses a disposable disinfection cap suitable for needle-free positive pressure connector, with the authorization date of 2015.08.19, which is composed of a sealing film 11, a shell 12, an elastic body 1 and a disinfectant 14. The sealing film is a circular plastic sheet, and its diameter is roughly the same as or slightly larger than the shell diameter, which makes it difficult to tear off the sealing film during use, which brings certain inconveniences. In addition, during use, after the infusion connector is connected to the disinfection cap, the end of the infusion connector abuts against the disinfection sponge in the disinfection cap, causing the sponge to dent, and the end of the infusion connector partially contacts the disinfection sponge, but cannot contact the sponge completely, affecting the disinfection effect. Utility Model Content

[0004] In order to overcome the existing technical defects and solve the technical problem that the sealing film on the existing disinfection cap is inconvenient to tear off, the purpose of the utility model is to provide a disposable infusion connector disinfection cap to solve the above technical problem.

[0005] The technical solution adopted by the utility model to solve the technical problem is as follows:

[0006] According to one aspect of the utility model, a disposable infusion connector disinfection cap is designed, comprising: a cap body, a sponge, a sealing sheet and a disinfectant, wherein the cap body is provided with a receiving cavity with an open lower end, the side wall of the receiving cavity is provided with an internal thread, the sponge and the disinfectant are arranged in the receiving cavity, the sealing sheet is fixedly connected to the lower end of the cap body to seal the opening of the receiving cavity, and a gripping sheet for pinching with fingers extends from one side of the sealing sheet.

[0007] By adopting the above technical solution, a gripping piece for fingers to pinch is extended on one side of the sealing piece. When the disinfection cap is used, the sealing piece can be easily torn off by pinching the gripping piece. It is simple and convenient, has good practicality, and brings great convenience when used.

[0008] In order to better solve the above technical defects, the utility model also has a better technical solution:

[0009] In some embodiments, the cap body includes a cap seat and a cap cover disposed on the top of the cap seat, and a plurality of ribs with triangular cross-sections are distributed on the outer circumference of the cap cover.

[0010] In some embodiments, a plurality of grooves are distributed around the outer circumference of the cap seat.

[0011] In some embodiments, the sealing sheet is an aluminum foil sheet, and the outer side of the gripping sheet is provided with an arc surface.

[0012] In some embodiments, the width of one end of the sealing sheet is greater than the width of one end of the grasping sheet.

[0013] In some embodiments, the top of the cap is a hemispherical structure.

[0014] In some embodiments, a conical or circular structure receiving groove is provided in the middle of the bottom of the sponge for inserting the infusion connector and abutting against the side thereof. By providing a groove on the sponge, when the infusion connector is connected to the disinfection cap, one end of the infusion connector can be inserted into the groove, so that the side wall of the end to be disinfected can be completely in contact with the sponge, thereby ensuring the disinfection effect.

[0015] In some embodiments, a plane is provided at the bottom of the accommodating groove for the end surface of the infusion connector to abut against. BRIEF DESCRIPTION OF THE DRAWINGS
