Abstract

The utility model discloses a liquid soft package applicable in solvent compartment, blood bank and pharmaceutical factory manufacturing large amount of liquid. The new liquid flexible package, in rectangle or square similar with the current one, is provided with a rounded eurohole at its one end to facilitate the transfusion in suspended type; two tubes are arranged at another end, one of which served as a perfusion tube sealed with a rubber stopper at the mouth to facilitate the insertion of a disposable syringe needle for venous transfusion and another as a chemical feed tube composed of a filter, a cardiac valve-type checkvalve, a neilsbed and a piston cap. The utility model has the advantages of insulating the air and intercepting the indissolvable particulate during feeding, thus preventing the abnormal transfusion due to the polluted particulate and solving the particulate pollution of venous transfusion to make the venous transfusion more safe and effective, which enhances the cure rate, improves the nursing and promotes the patients' recover.

Description

The new liquid soft packaging bag

Technical field this utility model belongs to medical instruments field, relates to the medicinal liquid packing technique.

The background technology venous transfusion is still one of main method of hospitalize disease at present.Along with the appearance of liquid soft package bag, venous transfusion by open transfusion to the closed transfusion transition.Treatment during disease the liquid in the transfusion bag most only as pharmaceutical carrier, and what really play therapeutical effect is to need the medicine that adds.Transfusion all will add one or more medicines in transfusion bag each time in treatment, but the particulate matters such as bacterial virus that the ampoule that forms in the process of making up a prescription is set up a separatist regime by force of arms in chip, rubber stopper chip, medicine crystallite, the dust can't be avoided.Up to now, in the process of making up a prescription, dosing in transfusion bag (or infusion bottle) is just directly thrust dosing by syringe needle, and microgranule together enters in the infusion bottle in company with medicine and pollutes.These microgranules enter the untoward reaction that causes behind the human body and mainly contain heat source response, anaphylaxis, phlebitis, the little bolt of blood vessel or the like, increase patient's misery.Modal is that rubber scraps swims in the liquid or in the tube for transfusion, as seen naked eyes cause medical tangle easily.I think that holding back microgranule through filter before medicine adds transfusion bag is the best method of preventing particle contamination in the venous transfusion at present.

Summary of the invention innovation part of the present utility model is: increase a drug feeding pipeline that has filter on the basis of existing liquid soft package bag, purpose is to be trapped in the insoluble microparticle that produces in the process of making up a prescription, the transfusion untoward reaction that prevention is caused by particle contamination improves the venous transfusion cure rate.This utility model technical characterictic: new liquid soft packaging bag outward appearance is rectangle or square, establishes a hanging hole for one of the new liquid soft packaging bag, is convenient to the suspension type transfusion; Be provided with two tubule roads in the other end: liquid-transport pipe-line and drug feeding pipeline.Wherein the structure of drug feeding pipeline is: at the drug feeding pipeline internal orifice the unidirectional flap valve of a heart valve membrane type is set, medicinal liquid can only be advanced can not be gone out, and purpose is to prevent from that the outflow of bag inner liquid medicine increases in the dosing process to pollute; At the drug feeding pipeline collar extension needle stand and a piston cap that is connected with needle stand are set, purpose is the convenient and minimizing opportunities for contamination of dosing; Add a filter between the internal orifice of drug feeding pipeline and collar extension, purpose is to be trapped in the particulate matter that produces in the process of making up a prescription, and reduces the generation of transfusion untoward reaction.The collar extension of liquid-transport pipe-line seals with rubber stopper in addition, is convenient to that thorn is inserted, fixing Disposable syringe needle for transfusion device.

This utility model provides a kind of closed liquid soft package bag, is applicable to that flexible package punch is carried out in the pharmaceutical factory of Drug Manufacturing Room, blood station, the big liquid of production.The design can farthest reduce particle contamination, make venous transfusion more seal, safer, improve the effective percentage of venous transfusion treatment disease.Reasonable in design, simple to operate, convenient and practical, there is excellent popularization to be worth.

Description of drawings: accompanying drawing one is this utility model structural representation (figure two is disposable syringe structural maps, cooperates the auxiliary view of explanation specific operation process, and is irrelevant with this patent).

Figure one: 1, new liquid soft packaging bag 6, needle stand

2, liquid-transport pipe-line 7, piston cap

3, rubber stopper 8, the unidirectional flap valve of heart valve membrane type

4, drug feeding pipeline 9, hanging hole

5, the connecting line of filter, 10, needle stand and piston

Two: 11 disposable syringes 12 of figure, disposable syringe nipple

The specific embodiment: aspirate required medicine with disposable syringe (11) earlier, open the flexible connection of needle stand (6) and piston cap (7) on the liquid soft package bag, syringe nipple (12) is connected with needle stand (6), then the medicine in the syringe is pushed gently, medicine is held back through filter (5) and is washed unidirectional flap valve (8) again open behind the microgranule and enter in the liquid soft package bag (1), push away the medicine external pressure that finishes and remove flap valve (8) auto-closing.Dosing finishes and connects needle stand (6) and piston cap (7), and purpose is that protection needle stand (6) is not contaminated.The preparation of venous transfusion medicated bag is finished, and prepares to give patient infusion then.Characteristics of the present utility model: microgranule is dammed outside filter, stops from the source to pollute, and makes venous transfusion safer, and is more effective.

Claims (2)

1, new liquid soft packaging bag, by liquid soft package bag (1), liquid-transport pipe-line (3), drug feeding pipeline (4) is formed, it is characterized in that drug feeding pipeline (4) is by a filter (5), the heart valve membrane type structure (8) of a unidirectional opening, a needle stand (6), a piston that is connected with needle stand (7) is common to be formed.

2, novel dense body soft packaging bag according to claim 1 is characterized in that between needle stand (6) and the piston (7) it being to flexibly connect, and is connected by line (10).
