Embodiment 1

[0035] Such as Figure 1-7 As shown, the embodiment of the present invention provides an infusion connector for preventing infection, comprising an upper housing 1, a lower housing 2 communicating with the upper housing 1, and a piston 3 containing anti-infective drugs, wherein the piston 3 is arranged on In the inner cavity of the upper housing 1.

[0036] Furthermore, the anti-infective drug is minocycline hydrochloride, rifampicin or a mixture of the two.

[0037] Among them, minocycline hydrochloride is a broad-spectrum, high-efficiency, quick-acting, and long-acting semi-synthetic antibacterial tetracycline antibiotics, which interfere with the binding of aminoacyl transfer RNA to the receptor site on the messenger RNA ribose appropriate receptor site. Synthetic, so it plays an antibacterial role, with good antibacterial activity and long half-life.

[0038] Among them, rifampicin is a common broad-spectrum antibiotic drug, which can firmly bind to b of DNA-dependent RN...

Embodiment 2

[0054] An embodiment of the present invention provides a method for preparing an infusion joint for preventing infection, which is used to prepare the infusion joint for preventing infection described in Example 1. The method specifically includes the following steps:

[0055] S1. Put two solvents, methanol with a concentration ≥ 99% and ethyl acetate with a concentration ≥ 98%, in a glass container, stir with a stirrer for 5 to 20 minutes, add anti-infective drugs into the glass container and continue stirring until fully Dissolved to prepare anti-infective liquid.

[0056] S2. The anti-infective liquid is heated with a constant temperature heater, so that the temperature of the anti-infective liquid reaches 30-60 degrees and remains stable.

[0057] S3. Completely immerse the piston carrier in the heated anti-infective liquid for 10-60 minutes, take it out, wash the remaining anti-infective liquid on the piston carrier with purified water except the incision, and then place ...

Embodiment 3

[0062] An embodiment of the present invention provides a method for preparing an infusion joint for preventing infection, which is used to prepare the infusion joint for preventing infection described in Example 1. The method specifically includes the following steps:

[0063] S1. Put two solvents, methanol with a concentration ≥ 99% and ethyl acetate with a concentration ≥ 98%, in a glass container, stir with a stirrer for 5 to 20 minutes, add anti-infective drugs into the glass container and continue stirring until fully Dissolved to prepare anti-infective liquid.

[0064] S2. The anti-infective liquid is heated with a constant temperature heater, so that the temperature of the anti-infective liquid reaches 30-60 degrees and remains stable.

[0065] S3. Completely immerse the piston carrier in the heated anti-infective liquid for 10-60 minutes, take it out, wash the rest of the anti-infective liquid on the piston carrier except the incision with purified water, and then plac...

Abstract

The invention relates to the technical field of infusion connectors, in particular to an infusion connector for preventing infection and a preparing method thereof. The infusion connector for preventing the infection comprises an upper shell, a lower shell communicated with the upper shell and a piston which contains an anti-infective drug, wherein the piston is arranged in an inner cavity of theupper shell. By means of the infusion connector for preventing the infection and the preparing method thereof, the occurrence of catheter-related bloodstream infection can be effectively prevented, the infusion connector is simple in structure and easy to operate, and has a good automatic sealing effect, and disinfection is simple and thorough.

Description

technical field [0001] The invention relates to the technical field of transfusion joints, in particular to an infection-preventing transfusion joint and a preparation method thereof. Background technique [0002] During clinical trials, when a patient needs long-term infusion, a catheter is usually placed outside the body for infusion. The existing needle-free connection infusion technology has normal and positive pressure connections. Ordinary infusion connectors are usually used for 1 to 5 days, and positive pressure connections are usually used for less than 15 days. Because bacteria are easy to invade and are not easy to clean, they need to be replaced frequently, which makes patients prone to catheter-related bloodstream infections, and the indwelling time is short, which increases the economic cost of patients. Burden and workload of healthcare workers. Contents of the invention [0003] (1) Technical problems to be solved [0004] The purpose of the present inven...
