Description

Transfusion tube

Technical Field

The utility model belongs to the technical field of medical auxiliary instruments, and particularly relates to an infusion tube.

Background

In the clinical treatment process, a plurality of medicines are required to be pumped into veins of patients, particularly critical and critical patients at a constant speed in a micro-scale manner to achieve the purpose of treatment, in emergency treatment and ICU, the medicines are pumped into the veins of the patients at a constant speed in a micro-scale manner to become an indispensable treatment method in clinic.

Usually at the in-process of infusion treatment each time, need inject many bottles of injection, current transfer line is many single bottle plug, can only once install a bottle of injection, has dripped a bottle of injection after, needs medical personnel in time to change, and medical personnel's work load is big, and when the disease is more, and medical personnel are difficult to help the disease in time to change the injection to arouse the anxiety of disease and discontented. At present, there is also an infusion tube provided with a plurality of bottle plug plugs with regulators, which can install a plurality of bottles of injection liquid on the infusion tube at one time, but the regulators on different bottle plug plugs are manual, and still require medical staff or patients to operate manually, so that after the injection liquid installed on one bottle plug is dripped, the infusion liquid on another bottle plug is switched, the patients stand by themselves to be switched inconveniently, and the workload of the medical staff is still large. Therefore, the infusion tube provided with the plurality of bottle stopper plugs can only switch the injection on different bottle stopper plugs through the manual operation regulator to inject, so that the use is troublesome, and the workload of medical staff is difficult to effectively reduce.

Meanwhile, after the infusion bottle of the existing infusion apparatus is emptied, if a patient does not control the regulating switch or medical staff cannot change liquid in time, the liquid medicine often drops below the Murphy's dropper, so that air in the infusion bottle enters the infusion tube in a bubble mode. Therefore, the nursing staff need to remove the air bubbles in the infusion tube when changing the liquid every time, which not only brings certain trouble to the nursing staff, but also is easy to pollute.

SUMMERY OF THE UTILITY MODEL
