Description

Disposable multi-channel infusion connector

Technical Field

The utility model relates to the technical field of infusion connectors, in particular to a disposable multi-channel infusion connector.

Background technique

The medical infusion three-way tube is composed of a three-way tube, a one-way valve and an elastic plug. In clinical work, in order to achieve the purpose of rapid treatment, it is often necessary to open two venous channels for patients. Multiple venous punctures in a short period of time not only increase the pain of patients, but also cause congestion at the puncture site. It is difficult to leave superficial vein catheters in many elderly patients, and deep vein catheterization is not possible. In view of this, three-way tubes are used clinically.

Usually, clinically used tees require two or three tees to be connected together if there are multiple passages. One problem is that bubbles are easily generated at the connection points, and the other problem is that they are easily disconnected. When the tees are connected into a passage, the liquids in the multiple pipes are mixed together. In the case of critically ill patients, incompatibility is easily generated, and multiple drug solutions are easily mixed and reacted. Critically ill patients need more passages, and the opening of the passage liquid is closer to the indwelling needle, so its pressure is relatively large, which can easily cause other liquids to mix and become turbid. At the same time, multiple tees are connected together, and a large string of tees on the patient's arm is easily broken, causing discomfort to the patient.
