Description

Y-shaped dustproof aseptic flow needle-placing infusion connector

Technical Field

The utility model belongs to the technical field of medical consumables and specifically relates to a Y-shaped dustproof aseptic flow needle infusion joint.

Background

At present, the y-shaped transfusion joint can be connected with an injector, a transfusion device and a transfusion device, and is particularly used for intravenous transfusion patients, such as children, chemotherapy patients, patients with imbalance of electrolyte balance, critical patients and patients who continue to be rescued, and the inner part of the y-shaped transfusion joint is always kept in a sterile state by an outer cap. Before infusion by the y-shaped infusion joint, the tube is flushed by 10ml of normal saline, and infusion is carried out after the smoothness of the catheter is confirmed. After the transfusion, 10-20ml of normal saline is injected in a continuous pulse mode, and finally 2-5ml of saline or heparin saline is used for separating the syringe while directly pushing the piston of the syringe, namely the pulse flushing pipe and the positive pressure sealing pipe. When the y-shaped transfusion joint is not butted with the joint of a transfusion tube or an injector in use, the outer cap of the y-shaped transfusion joint is usually exposed outside, the upper end surface of the outer cap is easy to contact with skin or clothes, so that various impurities are adhered to the upper end surface of the outer cap, after the use, the outer cap is directly covered on the y-shaped transfusion joint, when the y-shaped transfusion joint is used again, the disinfection effect can be achieved by increasing the disinfection area and the disinfection frequency, the working efficiency is influenced, if incomplete disinfection exists, the treatment and the quick recovery of patients can be influenced, particularly for patients with hematopathy, tumor patients and critical patients with low immunity during chemotherapy and radiotherapy, any pollution source outside possibly causes great threat to the health and even the life of the patients, how can avoid the heavy clothes and skin metabolic debris in winter, and avoid bacteria, foreign matter, and the like caused by exposure in summer, The pollution of dust and foreign matters causes the needle-free closed infusion joint to be in an aseptic state as much as possible, and the technical problem which is difficult to solve in various hospitals for a long time is solved.

For the above reasons, a y-shaped dust-proof sterile flow needle infusion connector has been developed.
