Description

Simple transfusion system

Technical Field

The utility model belongs to the technical field of medical instrument, specifically a simple and convenient transfusion system.

Background

The common transfusion device in the medical field is composed of a bottle stopper puncture outfit, a dropping funnel, a conduit, a flow regulator, a liquid medicine filter, an intravenous transfusion needle and the like, when liquid medicine enters the dropping funnel, the liquid downwards discharges gas in the dropping funnel to form gas-liquid mixture which enters a lower conduit to generate bubbles, medical staff must completely remove the bubbles in the conduit to carry out transfusion, and nursing staff, patients and family members of the patients need to observe the liquid condition in the transfusion bottle at any time in the transfusion process, so that when the transfusion is finished, blood rises back into the whole set of transfusion device due to the fact that the transfusion needle is not pulled out in time, or the liquid level drops too low to cause the gas to enter the human body to cause air embolism and other adverse consequences.

The infusion bottle and the infusion apparatus that use clinically at present are separated, just can be linked together by medical personnel when using for medical personnel are time-consuming at the during operation, hard, and careless very easily receive the pollution moreover, bring unnecessary trouble for the patient. Compared with the safety infusion apparatus, the invention saves raw materials such as spring clips, multi-channel hoses and the like, is more practical than the traditional medicine-adding puncture bottle stopper, and can avoid the phenomena of needle head blockage, bending, breaking and the like caused by sundries. When the medicine is added through the medicine adding port of the hard rubber nut guide pipe, the phenomena of needle head blockage, bending and breaking are avoided.
