Continuous infusion apparatus with automatic air exhaust function

Abstract

The invention relates to a continuous infusion apparatus with the automatic air exhaust function. The continuous infusion apparatus comprises an infusion apparatus upper part (1), an infusion apparatus middle part (2) and an infusion apparatus lower part (3), wherein the infusion apparatus upper part (1), the infusion apparatus middle part (2) and the infusion apparatus lower part (3) are connected in sequence. The continuous infusion apparatus is characterized in that the infusion apparatus middle part (2) comprises a regulating drip tube (21), and the regulating drip tube (21) comprises an infusion controller (4) and a drip tube body (5). With the continuous infusion apparatus with the automatic air exhaust function, on one hand, the problem that during the infusion process adopting a plurality of infusion bottles, the infusion bottles need to be replaced manually and frequently is solved, so that abundant time and effort of medical staff are saved, on the other hand, the undesirable phenomena that the liquid medicine is wasted, the connecting hole is infected, blood returns, air enters the human body, and the like are avoided, and thus the psychological burden of patients and the medical staff is greatly alleviated.

Description

[0001] technology field [0002] The invention relates to the medical field, in particular to a continuous infusion set with an automatic exhaust function. technical background [0003] Infusion sets are commonly used medical devices for intravenous injection, such as figure 1 As shown, the infusion set is generally composed of a bottle stopper piercer protective cover, a bottle stopper piercer, an air filter, a water stop clip, a Murphy's dropper, a long infusion catheter, a flow regulating device, a liquid medicine filter, and a conical joint. The infusion set usually has only one infusion channel, the upper end is connected with the infusion bottle, and the lower end is used in conjunction with the intravenous infusion needle, and is mainly used for clinical gravity infusion. When intravenous clinical infusion is actually used, it is usually a continuous infusion of multiple infusion bottles. Due to the different mechanisms of action of drugs and the mutual interference be...

AI Technical Summary

Problems solved by technology

The process is very cumbersome and time-consuming, and when the squeezing action is slightly careless, a large number of small air bubbles will be attached to the inner wall of the infusion tube on the lower side of the infusion set Mufei's dropper. In order to discharge these air bubbles, the medical staff need to use their fingers The process of flicking the tube wall of the infusion set is very cumbersome and the effect is not ideal

2. When multiple bottles of liquid infusion are infused continuously, it is necessary to manually replace the infusion bottle after each bottle of liquid medicine is infused

On the one hand, since medical staff often need to take care of infusion patients in multiple wards, it takes a lot of time for medical staff to manually replace the infusion bottle, resulting in unnecessary waste of energy; on the other hand, if the infusion liquid level is low when changing the infusion bottle If the lower part of the muffi's dropper is used, it is necessary to re-air or re-inject the IV: if the liquid level is only a short distance below the dropper, the infusion tube is usually wound around the finger from the bottom up to squeeze out the air gradually; if If the liquid level is much lower than the dropper, the conical joint needs to be opened to discharge the air from the lower end, but this process will inevitably cause waste of the liquid medicine, and at the same time, it is easy to cause infection of the interface and a small amount of air entering the human body through the infusion needle

The method of expelling air from the outside of the infusion set by squeezing the wall of the infusion tube will also cause damage to the infusion tube. The damaged infusion tube will affect the infusion performance of the infusion set, thereby reducing the reliability of the infusion set, and in severe cases, it will cause infusion accidents.

Therefore, in order to prevent the liquid level from falling below the Murphy's dropper, medical staff, patients and family members need to take care in real time, causing unnecessary tension and psychological burden on the three

3. The current clinical intravenous infusion cannot automatically stop the infusion

At the end of the infusion, if the medical staff does not take care of it in time, the liquid level will drop too low, which will cause blood back phenomenon, and in severe cases, the gas will enter the human body and cause gas embolism and other adverse consequences

4. For blood transfusion or precious liquid medicine, manual confirmation before transfusio
