Abstract

The utility model belongs to an infusion bag used for the clinical care, which comprises a bag body, compounding liquid, dosage and an infusion tube. The infusion bag can directly input vein liquid into the bag body from different liquid bottles and inject the physic liquid into a dosage tube, compounds the mixed liquid according to any proportion and feed liquid towards an infusion system through the infusion tube. The utility model not only assures the sterile operation in the process of liquid compounding and infusion, but also enables the residual vein liquid in the original liquid bottle to be saved in the no pollution status. Therefore, the utility model has the advantages of scientific and accurate liquid compounding, convenient use, portability, etc., effectively avoids the pollution and the infusion reaction brought by the pollution, and reduces the waste of the physic liquid. The utility model can be matched with disposable infusion units.

Description

Disposable mixing infusion bag

This utility model belongs to the transfusion bag that clinical treatment is used, and particularly a kind of sterile sealing type also can mix quiet transfusion bag with liquid, can be supporting with disposable transfusion device, and make disposable infusion and use.

At present, in clinical treatment and depositing the different infusion set of two classes--repeatedly used Glass liquor hanging bottle and disposable transfusion device.The former advantage is can be according to patient's needs, and in different medicinal liquid ratios, obtaining liq consumption, tensile advantage easily, but exist aseptic poor easily cause polluting and infusion reaction, carry and shortcoming such as the inconvenience of sterilizing; Though disposable infusion has overcome the above-mentioned shortcoming of transfusion bottle, has brought the dosing inconvenience, under the situation that is subjected to original-pack vein liquid measure restriction, need uncork to allocate, thereby destroyed sterile working's program, lost the high advantage of disposable infusion aseptic.In addition, because the inconvenience of the medicinal liquid after the uncork is preserved, also not allowing to give over to transfusion next time uses, therefore when dosing, often unnecessary vein liquid is outwelled, both caused unnecessary waste, increased the weight of patient's burden again, this is concerning especially true such as the little patient of fluid volumes such as child, Water-Electrolyte disorder.

The purpose of this utility model is to provide a kind of and can measures on demand and the ratio dosing under aseptic condition easily, can directly provide the transfusion bag of vein with liquid to disposable transfusion device simultaneously.To reach purposes such as in whole venous transfusion process, all guaranteeing sterile working, dosing convenience and saving medicinal liquid.

Solution of the present utility model is to adopt latex and polyesters avirulence medical material to make transfusion bag.This transfusion bag comprises the bag of splendid attire and mixed venous liquid, in bag afferent veins liquid liquid distribution pipe, inject the pipe and the tube for transfusion of medicinal liquid is provided to transfusion device of making up a prescription of medicinal liquid; Liquid distribution pipe is positioned at the transfusion bag top with the pipe that makes up a prescription, and tube for transfusion then is positioned at the transfusion bag below; Bag and liquid distribution pipe, tube for transfusion, the sealed connection of employing between the pipe of making up a prescription; Liquid distribution pipe can adopt two single tubes, can also be tee T, can establish a macropore syringe needle that is used for drain in the end of liquid distribution pipe, also can not establish and socket syringe needle more in use; At the tube head that makes up a prescription one cap stopper in order to seal is set also; The tube for transfusion tube head then adopts fixed sealing.This utility model promptly adopts such scheme to realize its goal of the invention.

This utility model is owing to adopt the mode of disposable infusion, liquid distribution pipe by the band syringe needle directly injects vein liquid bag and carries out the allotment of arbitrary ratio from former liquid bottle under the sealing situation, and advance medicine by the pipe that makes up a prescription, and by tube for transfusion directly to the disposable transfusion device feed flow.Not only guaranteed the sterile working's program in preparating liquid and infusion process, and made remaining vein liquid still can be in pollution-free state preservation, as the usefulness of infusing next time, to save vein liquid, to reduce patient's expense.Therefore, this utility model has not only guaranteed science, the accuracy of transfusion compatibility program, and the infusion reaction of having avoided germ contamination effectively and therefore having caused has reduced the waste of medicinal liquid, reduced patient's drug cost to a certain extent, but also had easy to use and carry.Be fit to the characteristics that use in open-air and battlefield etc.

Accompanying drawing and description of drawings

Fig. 1 is the structural representation of this utility model embodiment one;

Fig. 2 is embodiment two structural representations;

Fig. 3 is this utility model user mode figure.

Among the figure: 1, bag, 2, the pipe that makes up a prescription, 3, liquid distribution pipe, 4, syringe needle, 5, actuator, 6, tube for transfusion, 7, original-pack vein liquid and liquid bottle, 8, airway, 9, disposable transfusion device.

Embodiment one

The bag 1 of present embodiment, the pipe 2 that makes up a prescription, liquid distribution pipe 3, tube for transfusion 4, all adopt the medical latex manufacturing.Wherein bag 1, blowing form, promptly earlier it is blow molded into the long tubular that diameter is about 10cm, cut off by every joint 20cm then, liquid distribution pipe 3 and make up a prescription pipe 2 by be stuck in about the 25mm of space between the bag mouth and with bag mouth together hot pressing seal, the liquid distribution pipe of present embodiment adopts two single tubes, about every long 35cm, diameter phi 4mm, every tube head socket one macropore syringe needle 4 makes up a prescription and manages 2, is about 4cm, diameter phi 5mm, pipe end adopt cap stopper to seal; The other end of bag and tube for transfusion 6 hot pressings seal, and tube for transfusion 6 is about 7cm, and diameter phi 4mm, tube head do heat-sealing mouthful processing; Actuator 5, present embodiment adopts pulley folder (also available alligator clamp).After making, transfusion bag carries out sterilization treatment, vacuum packaging.With sleeve pipe syringe needle 4 is put before the packing, both can avoid using preceding pathogen contamination, also prevent that syringe needle punctures bag in the transportation.

Embodiment two

Present embodiment adopts a tee T as liquid distribution pipe 3, wherein person in charge and bag 1, sealed connection, other two as dosing usefulness, tube head is each socket one macropore syringe needle also.All the other are all with embodiment one.

When this utility model uses, earlier transfusion bag is taken out, dial the conduit that removes syringe needle 4, respectively syringe needle is inserted in the corresponding vein liquid bottle of oral area after sterile-processed, insert an airway 8 at each bottleneck simultaneously; Then liquid bottle 7 is hung on the drip stand together with transfusion bag 1, opens the cap stopper of the pipe 2 that makes up a prescription and pulley folder 5 is transferred to maximum opening, the vein liquid in each liquid bottle flows into rapidly in the transfusion bag 1 through liquid distribution pipe at this moment.According to recipe quantity,, join when enough to press from both sides when the vein liquid in a certain bottle its liquid stream is blocked by pulley according to the scale value on the liquid bottle; If need in vein liquid, to allocate into other medicine such as antibiotics etc., can mouthful inject in the bag through making up a prescription by needle tubing, shake up and get final product.After preparing medicinal liquid, in the macropore syringe needle insertion tube for transfusion 6 with the disposable transfusion device afterbody, the air of getting rid of in the transfusion device can be made venous transfusion to patient.
