Exhaust and liquid stopping infusion apparatus

Abstract

The invention belongs to the field of medical instruments, and particularly relates to an exhaust and liquid stopping infusion apparatus. The exhaust and liquid stopping infusion apparatus comprises a drip chamber. An exhaust device and a liquid stopping device are arranged in the drip chamber. The exhaust device comprises an exhaust tube and a hydrophobic air filtering medium, wherein the exhaust tube is arranged at the bottom of the drip chamber and communicates an inner cavity of the drip chamber with the external atmosphere, the air filtering medium is fixed to and matched with the end face, on the inner cavity of the drip chamber, of the exhaust tube, and the upper surface of the air filtering medium is a cambered surface protruding towards the inner cavity of the drip chamber in the axial direction of the exhaust tube. The liquid stopping device is an air blocking and water permeating component which is arranged at the lower portion of the inner cavity of the drip chamber and divides the inner cavity of the drip chamber into an upper portion and a lower portion. The exhaust and liquid stopping infusion apparatus is simple and reasonable in structure, the drip chamber does not need to be arranged reversely or squeezed when the exhaust and liquid stopping infusion apparatus is in use, operation is convenient, air inside the drip chamber can be smoothly exhausted through the air filtering medium and the exhaust tube, and the liquid level height inside the drip chamber is kept during infusion; the filtering effect of the air blocking and water permeating component in the liquid stopping device is obvious, and the liquid stopping performance is reliable; the whole infusion apparatus is safe and convenient to use and rapid and reliable.

Description

technical field [0001] The invention relates to an infusion device for exhausting and stopping liquid, which belongs to the field of medical appliances. Background technique [0002] Infusion is a treatment method widely used in clinical treatment, and safety is an indispensable and important condition for infusion. [0003] When the medicinal liquid in the ordinary infusion set enters the dripping funnel, it is very easy to form a mixture of gas and liquid, and the gas-liquid mixture will quickly enter the infusion pipeline below the dripping funnel, forming bubbles during infusion, which is harmful to the health of the patient. Threat, so when infusion, medical staff must completely discharge the air bubbles in the infusion catheter before infusion. The usual method is to invert or squeeze the dripping funnel after the cork piercer is inserted into the infusion bottle stopper, so that the medicinal liquid enters the dripping funnel, and when the dripping funnel is filled ...

AI Technical Summary

Problems solved by technology

The usual method is to invert or squeeze the dripping funnel after the cork piercer is inserted into the infusion bottle stopper, so that the medicinal liquid enters the dripping funnel, and when the dripping funnel is filled with about half of the liquid, quickly put the dripping funnel back into place. Return to the normal use state, even so, the pipe wall below the drip funnel often absorbs air bubbles, and the medical staff need to pinch the air bubbles with their fingers. This kind of operation method is cumbersome and brings great inconvenience to the medical staff.

[0004] After the liquid medicine is infused, if it is not treated in time, air will enter the pipeline, which will also pose a threat to the health of the patient

In order to avoid this situation, usually during clinical infusion, patients and medical staff need to pay attention to the remaining amount of liquid medicine at all times, which takes up a lot of energy and also causes great psychological pressure on patients. They often call doctors and nurses when there is a lot of liquid medicine remaining It is easy to cause conflicts in the relationship between doctors and patients, which is not conducive to the recovery of patients and the normal medical care work.
