Abstract

The utility model relates to a medicine adding device which can have less pollution, can not produce the rubber falling bits and can pump the liquid medicine. The utility model is mainly used for a transfusion bag with a flexible package, and the utility model belongs to the medical appliance for the medical treatment. A short needle tube, a short needle seat, a flexible tube, a long needle seat and a long needle tube are connected in sequence to form the utility model, wherein the components are sealed, so that the air can not leak. The needle tubes are pierced in a rubber plug without producing the falling bits. The flexible tube is flexible and transparent, and the flexible tube is matched with a flexible tube opening of a bag packing device. The long needle seat is matched with an air pump handle of which the inner part is provided with a liquid circulation pipeline and an air ventilation pipeline. The inner part of the air ventilation pipeline is provided with a filter, and the air ventilation pipeline can balance the pressure in a medicine bottle so as to make the liquid medicine pumped. The utility model can replace the traditional transfusion device and can be applied to the medicine adding field of the clinical transfusion bag with the flexible package.

Description

A kind of drug feeding device

The apparatus of using when technical field this utility model relates to a kind of transfusion bag dosing belongs to medical medical device.

The dosing injector operations of the present soft-packing transfusion bag of background technology, there are problems in the syringe dosing: 1. syringe front end straight hole is needled into plug and can produces the rubber exfoliation.2. closure is poor between the syringe of syringe and the nook closing member, easily causes its inner liquid medicine to pollute.3. the syringe front end does not have the structure of equalizing pressure, thrusts the powder medicine bottle, and the medicine bottle inner liquid medicine can not be drained.The summary of the invention the purpose of this utility model just provides the drug feeding device that a kind of pollution that is applied on the transfusion bag less, does not produce exfoliation, can drain medicinal liquid.

Technical scheme main body of the present utility model is a pipe, by the hour hand pipe, the hour hand seat, flexible pipe, the minute hand seat, the minute hand pipe is formed, the length needle tubing can be the side opening pin, do not produce exfoliation when thrusting plug, the hour hand pipe is connected on the hour hand seat, and the other end of hour hand seat connects flexible pipe, and flexible pipe is soft, transparent, supporting with the hose port of bagger, the other end of flexible pipe is connected with the minute hand seat, and the shape of minute hand seat and air pump handle are supporting, in fluid-through tube road and breather line are arranged, fluid-through tube road one end leads to the flexible pipe inner chamber, other end spreading needle tubing, and an end of breather line is parallel with the minute hand pipe, filter is arranged in the other end, can filter by the foreign bodies such as antibacterial in the gas.During use, the hour hand pipe thrusts in the transfusion bag mouth, the minute hand pipe thrusts in the medicine bottle, and when transfusion bag pressure increased, the bag inner liquid medicine flowed in the medicine bottle, when transfusion bag pressure reduces, the medicine bottle inner liquid medicine flows in the transfusion bag, and the pipe sealing that medicinal liquid passes through is good, pollutes few, the medicine bottle internal pressure is by the breather line balance on the needle stand, and the bottle inner liquid medicine can be drained.

Beneficial effect adds medicinal syringe with tradition to be compared, and it replaces loosely organized syringe with incorporate hour hand pipe, hour hand seat, flexible pipe, minute hand seat, minute hand pipe, makes it to pollute to lack, and does not produce exfoliation, and medicinal liquid can be drained.
