Anti-backflow infusion set

Abstract

The invention discloses an anti-backflow infusion set mainly comprising an infusion flexible tube, an intravenous infusion needle, a speed-control switch, a Murphy's dropper, two or above bottle plug puncture sets and two or above branch switches. The infusion flexible tube comprises a main pipe and two or above branch pipes. The lower ends of the branch pipes are all communicated with the upper end of the main pipe. The bottle plug puncture sets are connected to the upper ends of the branch pipes. The branch switches are connected to the middles of the branch pipes. The intravenous infusion needle is connected to the lower end of the main pipe. The speed-control switch and the Murphy's dropper are in sequential connection with the middle of the main pipe. The middles of the branch pipe are in one-step sequential connection with anti-backflow devices. By the use of the anti-backflow infusion set, solutions in the different medicine bottles are avoided being mixed. Particularly after linked with an automatic air-exhausting infusion set, the anti-backflow infusion set prevents the air from entering bodies of patients through the infusion bottles in use.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to an anti-reflux infusion set. Background technique [0002] The traditional infusion set mainly consists of an infusion hose, a cork puncturer connected in series on the infusion hose from top to bottom, a Murphys dropper, a speed control switch and an intravenous infusion needle. When in use, the bottle stopper piercer is inserted into the infusion bottle, and the intravenous infusion needle is inserted into the patient's body to realize infusion. This single-way structure infusion device can only be connected to one bottle of infusion bottle at a time, so after each bottle of medicinal liquid is transfused, medical personnel are required to pull out the cork piercer from one bottle of infusion bottle and insert it into another. bottle of infusion bottle. Considering that patients usually need to infuse two or more kinds of medicinal liquids to achieve the therapeut...

Problems solved by technology

This requires medical staff or patients to pay special attention to the state of the two-way branch speed-regulating switch, that is, it is necessary to ensure that one of the branch-circuit speed-regulating switches is completely closed. The position of the bottle changes to form a pressure gradient, so that the liquid on the side with high pressure enters the infusion bottle on the side with low pressure, causing the liquids in different infusion bottles to mix with each other; or due to improper operation, air enters the patient's body
