Problems solved by technology

[0002] At present, in the clinical field of intravenous infusion, disposable infusion sets are generally used. This type of infusion set has the following problems in the use process: when using ordinary infusion sets for infusion, it must be manually squeezed to introduce the liquid into the drip funnel. It is difficult, cumbersome, and time-consuming to remove the gas in the bucket and the infusion catheter. If the air bubbles cannot be removed well, the air bubbles will enter the patient's body with the liquid medicine, which may easily cause dangers such as air embolism.
After the infusion is completed, since there is no automatic stop fluid function, medical personnel need to replace the infusion bottle or pull out the infusion needle in time, otherwise air will enter the patient's body and cause air embolism, or other unsafe factors such as blood return, which will directly increase The work intensity and heavy mental burden of medical staff will cause serious consequences in the face of emergency infusion and rescue of critically ill patients

Abstract

The invention discloses an automatic exhaust and automatic liquid stopping dropping bucket and an automatic exhaust and automatic liquid stopping method of the dropping bucket. The dropping bucket comprises an upper dropping bucket cover, an exhaust device, a dropping bucket body and a liquid stopping device. The exhaust device comprises an air plug, an air filtering membrane, a clamping groove and an air guide pipe. The air plug is arranged in the clamping groove. The clamping groove is formed in the left side of the upper dropping bucket cover. The air guide pipe and the upper dropping bucket cover are of an integrated injection molding piece. The air filtering membrane is assembled between the air plug and the bottom end of the clamping groove in an interference fit mode. The tail end of the air guide pipe is provided with a side hole. The dropping bucket body is of a conical structure. The liquid stopping device is clamped between an antiskid rib and the bottom end of the dropping bucket body. The liquid stopping device comprises an upper liquid stopping cover, a lower liquid stopping cover, a clamping base and a liquid stopping membrane. The liquid stopping membrane can be set to be a double-layer liquid stopping membrane and can also be set to be a cylindrical liquid stopping membrane. The upper liquid stopping cover, the lower liquid stopping cover and the clamping base are jointly assembled in an interference fit mode to form the cylindrical liquid stopping membrane. By means of the automatic exhaust and automatic liquid stopping dropping bucket and the automatic exhaust and automatic liquid stopping method of the dropping bucket, the effects of automatic exhaust, automatic liquid stopping, blocking resistance and the like can be achieved.
