Multipurpose medical anti-reflux connector

Abstract

The invention discloses a multipurpose medical anti-reflux connector. The multipurpose medical anti-reflux connector comprises an outer cover, a first infusion tube and a second infusion tube. The left side surface of the outer cover is fixedly connected with the first infusion tube and the second infusion tube. The top ends of the first infusion tube and the second infusion tube are both fixedlyconnected with a third connecting tube. An inner cavity of the third connecting tube is fixedly connected with a first cannula. The two ends of the third connecting tube are fixedly connected with a blocking rod and a blocking head correspondingly. The top end of a second connecting rod is fixedly connected with a baffle. A fourth connecting tube is mounted on the right side of a first connectingtube. According to the multipurpose medical anti-reflux connector, by mounting the two infusion tubes, simultaneous infusion can be achieved under the situations that drugs are not replaced and the bodies of patients are not harmed, thus the workload of medical patient care is reduced, and the pain of the patients is reduced; and by mounting a check block and a check ring, the reflux phenomenon generated after drugs are infused is avoided, using is convenient, and the harm to the patients is reduced.

Description

Technical field [0001] The invention relates to the field of medical technology, in particular to a multi-purpose medical anti-reflux connector. Background technique [0002] At present, various infusions, blood transfusions, and drainage tubes are widely used in clinical treatment. However, in actual operation, due to changes in body position, pressure changes and other factors, it is easy to cause reflux, which can cause blockage of the pipeline, contaminate the device, and endanger the lives of patients in severe cases. . For example, if you encounter blood reflux during infusion, small blood clots are likely to form. The formation of blood clots with the infusion of the medicine constitutes a potential danger to the patient, and the reflux can easily block the needle and require re-puncture, causing pain to the patient and increasing medical staff. For example, the patent application number 201220199786.0 includes a pipe body, which is characterized in that the two ends of t...

Problems solved by technology

[0002] At present, various infusions, blood transfusions, and drainage tubes are widely used in clinical treatment, but in actual operation, due to changes in body position, pressure changes and other factors, it is easy to cause reflux, which will cause blockage of the pipeline, pollute the device, and endanger the life of the patient in severe cases.

For example, if you encounter blood backflow during infusion, small blood clots are likely to form, which poses a potential danger to the patient's thrombus formation along with the drug infusion, and the backflow is easy to block the needle, requiring re-puncture, causing pain to the patient and increasing the number of medical staff. For example, the patent application No. 201220199786.0 includes a pipe body, which is characterized in that the two ends of the pipe body are respectively provided with a liquid inlet port and a liquid outlet port, and the pipe body is provided with an anti-backflow device, although the anti-reverse The role of flow, but it is impossible to inject multiple drugs at the same time, and some medical measures cannot be realized
