Description

Communicating pipe for color identification transfusion

Technical Field

The invention relates to the technical field of infusion equipment, in particular to a communicating pipe for color identification infusion.

Background

In the clinical infusion process, the exhaust pipe often appears blocking phenomenon, leads to in the air can not get into the infusion bottle, influences the infusion and goes on smoothly, and this kind of trouble mostly needs to change the exhaust pipe and just enables the infusion and continue to go on, has both brought inconvenience and increased the consumption of transfusion system and has really been the problem that the urgent need was solved for nursing work.

The intravenous infusion is characterized in that liquid is directly input into veins by utilizing the principle that the internal pressure of an infusion system formed by atmospheric pressure and hydrostatic pressure is higher than the venous pressure of a human body, the maintenance of the atmospheric pressure in the infusion bottle is realized by continuously injecting air into an exhaust pipe communicated with the outside, the exhaust pipe automatically enters air along with the reduction of the internal pressure of the infusion bottle to keep the constant pressure in the bottle, so that the infusion is continuously carried out according to a plan, however, when the internal pressure of the infusion bottle is overlarge due to various reasons, the liquid enters a blood vessel through an intravenous infusion passage on one hand, and overflows outwards through the exhaust pipe on the other hand to soak a filter disc at the tail end of the exhaust pipe, and meanwhile, as medicine particles in the liquid are attached to the filter disc, the exhaust pipe is blocked, the.

When injecting the medicine mixture into the medicine bottle, can make inside pressure rise gradually, in the inserted one instant of puncture ware, the liquid medicine can flow to communicating pipe and transfer line fast, and the transfer line is because of having certain pressure for the human body, and communicating pipe is the same with the external world, therefore when pressure is higher, the liquid medicine can contact the filter element. Therefore, a communicating tube for color identification transfusion is provided.
