Abstract

The utility model relates to a medical infusion bag with a dosing mouth special for a valve, comprising an infusion bag body. An infusion mouth and a rubber stopper for closing the infusion mouth are arranged at one end of the infusion bag body; and the valve capable of infusing liquid medicines into the infusion bag body from the infusion mouth is arranged on the rubber stopper. In operation, a snap lid is pulled open, a syringe nipple is inserted into an outer opening of the valve to push a piston rod to move, a spring is compressed, a piston moves, the valve is opened, and the injected liquid medicines flow into the bag; and alternatively, liquid in the bag can be sucked into a syringe, the syringe nipple is pulled out, the piston moves due to the elasticity of the spring, the outer opening of the valve is plugged, the valve is closed automatically, and the liquid can not flow out. Therefore, a needle head does not need to penetrate into the bag directly, the pollution on the liquid is reduced, and the reaction of a patient subjected to infusion and other medical safety accidents are reduced. The clearance in the valve is larger than the inner diameter of the needle head, so that the time and labor of an operator are saved when the liquid medicines are sucked or injected. As only one small-sized valve is assembled on the rubber stopper at the mouth of the infusion bag, the structure of the medical infusion bag is simple.

Description

The medical infusion bags that has the special-purpose dosing mouth of valve

Technical field

This utility model relates to a kind of medical infusion bags, is to be used for pharmaceutical factory to be fabricated to the packaging bag of patient infusion with liquid.

Background technology

Structure according to present medical infusion bags; when in transfusion bag, extracting liquid or medicinal liquid being injected transfusion bag; still need be with a kind of traditional dispensing method; after extracting other medicinal liquids with syringe; needle pierces transfusion bag chewing gum plug; extract with needle tubing that syringe needle exposes for a long time in the process of other medicinal liquids in air; the antibacterial and the flying dust microgranule that pollute can be brought in the transfusion bag; when piercing through bag mouth glue lid; sometimes there is debris of rubber stopper to fall in the bag; polluted liquid, patient is prone to infusion reaction and other medical safety accidents.

Summary of the invention

The shortcoming of infusion reaction and other medical safety accidents takes place for the transfusion bag that overcomes present use causes patient easily.This utility model provides a kind of transfusion bag that has the special-purpose infusion port of valve-type, and the pollution of liquid can not only be stopped or reduce to this transfusion bag, reduce the generation of patient infusion reaction and other medical safety accidents, and the operator is time saving and energy saving.

For achieving the above object, this utility model adopts following technical proposals:

A kind of medical infusion bags that has the special-purpose dosing mouth of valve comprises the transfusion bag, the plug that an end of transfusion bag is provided with infusion port and seals this infusion port, and being provided with on plug can be with medicinal liquid from the intravital valve of this infusion port input transfusion bag.

As further improvement of the utility model, described valve is: one is fixed on the valve housing on the plug, be provided with in the valve housing and be communicated with the inside and outside cavity of infusion port, one piston, an end of piston are fastened on transfusion bag or the infusion port and can compress or strain the spring that described piston makes its airtight described cavity.

As further improvement of the utility model, the top of piston is provided with the supporter that is fixed in the infusion port, has space between supporter and the infusion port for medicinal liquid input transfusion bag, described piston be arranged at cavity above, described spring connects transfusion bag and piston, and compression piston makes its airtight described cavity.

As further improvement of the utility model, the piston rod that described piston has also connected, piston rod is positioned at cavity, is provided with through hole on the sidewall of piston rod and near the piston place.

As further improvement of the utility model, the outside of described infusion port is provided with the enclosing cover that is used to seal described infusion port.

As further improvement of the utility model, described enclosing cover is the easy-open lid that has draw ring.

Draw back easy-open lid during operation, syringe nipple inserts in the valve collar extension and pushes piston rod, and spring is compressed, piston moves, and valve is open, injects medicinal liquid direction in bag and flows into, also can extract syringe nipple, because the elastic force apply piston of spring moves in the liquid suction syringe in the bag, the block valve collar extension, valve is closed automatically, and liquid that can not flows out, and directly thrusts in the bag without syringe needle, reduce the pollution of liquid, reduce the generation of patient infusion reaction and other medical safety accidents.The valve internal space is big than the syringe needle internal diameter, and the operator is time saving and energy saving when extraction or injection medicinal liquid.

Compared with prior art, the beneficial effects of the utility model are, stop or reduce the pollution of liquid, reduce the generation of patient infusion reaction and other medical safety accidents, and the operator is time saving and energy saving.Only assemble a valvelet beyond the Great Wall at the transfusion bag chewing gum, simple in structure.
