Description

Multifunctional liquid medicine filter for internal medicine

Technical Field

The utility model belongs to medical care equipment field, specific theory relates to a multi-functional liquid medicine filter is used to internal medicine.

Background

Infusion (IV fluid) is a large dose (more than 100ml per administration) of an injection solution that is infused into the body by intravenous drip. Are usually packaged in glass or plastic infusion bottles or bags and contain no preservatives or bacteriostatic agents. When in use, the dropping speed is adjusted by the infusion apparatus, and the infusion apparatus continuously and stably enters the vein to supplement body fluid, electrolyte or provide nutrient substances. Because the dosage is large and the injection directly enters blood, the quality requirement is high, and the production process and the like have certain differences with the small needle injection.

Although the amount of Chinese infusion products is large, the outlet proportion is extremely low, and most of the Chinese infusion products are used for domestic patients. The 1998 society of Chinese chemical industry counted that the number of infusion produced was 19 billion bottles plus four or five billion bottles of home-made infusion in hospitals, which totaled no more than 24 billion bottles, with an average of less than two bottles per person. The aim of the enterprise at that time was to drive up to the foreign average (2 to 3 bottles) by expanding production and reducing prices to meet domestic patient needs. The result is that the dosage of Chinese transfusion is rapidly increased, the annual average growth rate is nearly 20 percent, and the transfusion becomes one of five major preparations in the pharmaceutical industry parallel to antibiotics, injections, tablets and the like.

At present, common infusion sets commonly used in the medical field are composed of a bottle stopper puncture outfit protective sleeve, a bottle stopper puncture outfit, an infusion short catheter, an exhaust short catheter, an air filter, a dropper, a dropping funnel, a flow regulator, an infusion long catheter, a liquid medicine filter and a disposable intravenous infusion needle. When the infusion is just started, the liquid medicine can be introduced into the dropping funnel from the infusion bottle only by manually squeezing the dropping funnel, and in the process that the liquid medicine enters the dropping funnel from the dropper through the pipeline, the liquid medicine is easy to discharge the gas in the dropping funnel downwards to form a gas-liquid mixture which enters the long infusion catheter, so that bubbles are generated. Therefore, before the medical staff carries out the infusion, the air bubbles in the long catheter of the infusion apparatus must be discharged as completely as possible manually.

The common method of artificial ventilation is: after the bottle plug puncture outfit is inserted into the infusion bottle plug, the dropping funnel is firstly hung upside down, meanwhile, the dropping funnel is squeezed by hands, so that the liquid medicine enters the dropping funnel, after a certain amount of liquid is filled in the dropping funnel, the dropping funnel is put down, most of bubbles can be removed, but a small amount of small bubbles are adsorbed on the inner wall of the infusion long catheter, the infusion long catheter needs to be flicked by fingers of medical personnel, the adsorbed bubbles can only slowly rise into the dropping funnel, the process of manually discharging the bubbles is not only tedious and time-consuming, and when the working strength of the medical personnel is increased, the emergency infusion and the rescue of patients are not facilitated. Meanwhile, in the process of infusion, due to the movement of a patient or gravity and the like, the liquid medicine filter and the intravenous infusion needle can be separated and fall off, and adverse effects are caused.
