Liquid-stopping tank-type automatic exhaust liquid-stopping infusion apparatus

Abstract

The invention discloses a liquid-stopping tank-type automatic exhaust liquid-stopping infusion apparatus. A dropping funnel cover (2a), an exhaust hole (2b), an exhaust filtering hole (2c) and an air filtering hole (2d) are in injection molding on a bottle stopper puncture device (2), an air filtering membrane (4) is installed inside the air filtering hole (2d) and sealed by an air filtering cap (3), an automatic exhaust device (5) is installed on the dropping funnel cover (2a), a dropping funnel (6) is connected at the bottom of the dropping funnel cover (2a), an automatic liquid-stopping device (7) is installed on the bottom face (6a) inside the dropping funnel, a liquid dropping opening (6b) is formed in the bottom of the dropping funnel (6) in an injection molding mode, one end of a long infusion catheter (9) is connected with the liquid dropping opening (6b), the other end of the long infusion catheter (9) penetrates through a flow regulator (10) to be connected with a medicine liquid injection part (11), a flareless fitting (12) and a vein needle (13), and the safe infusion apparatus is integrally formed. According to the liquid-stopping tank-type automatic exhaust liquid-stopping infusion apparatus, automatic exhaust is achieved, liquid medicine automatically stops flowing, the exhaust operation steps are simplified, working intensity is relieved, the structure is simple, and the liquid-stopping tank-type automatic exhaust liquid-stopping infusion apparatus is safe and reliable.

Description

technical field [0001] The invention relates to a sterile medical instrument for clinical infusion, in particular to a liquid-stopping cylinder type infusion set with automatic exhaust and automatic liquid-stopping functions. Background technique [0002] At present, the common infusion sets commonly used in the medical field are composed of a cork piercer protective cover, a cork piercer, an air filter, a drip funnel cover, a drip funnel, a long infusion catheter, a flow regulator, a liquid medicine filter, injection parts, It consists of a two-way conical joint and a disposable intravenous infusion needle. At the beginning of the infusion, the ordinary infusion set must manually squeeze the dripping funnel to introduce the medicinal liquid from the infusion bottle into the dripping funnel. The gas in the bucket is discharged downwards to form a gas-liquid mixture into the long infusion catheter, thus generating air bubbles. At the same time, due to the surface tension of ...

Problems solved by technology

[0003] In the clinical infusion process, usually a medical staff has to take care of the infusion of patients in several wards. If the infusion bottle is replaced in time or the infusion needle is pulled out, this will cause the blood to rise back into the entire set of infusion set tubes, or the liquid level will drop too low, which will cause gas to enter the human body and cause gas embolism and other adverse consequences, which will bring great harm to medical staff, patients or their families. heavy mental burden
