Abstract

The utility model discloses a distribution soft infusion bag, including a soft bag body. On one end of the soft bag body is equipped with fluid joint. On the bottom of the soft bag body are equipped with bag-hanging mouth and location mouth. The soft bag body is divided into three chamber flow fields, upper, middle and lower. The soft joint seal is equipped between the adjacent chamber flow fields. The mould cape is connected with the top of the fluid joint. The disposable distribution soft infusion bag of the utility model is made of non PVC composite membrane for disposable use. It is safer and more soothed to use when drug liquid is prepared in the sealing condition. Some drugs allergic to the light, oxygen and vapor can be protected through recovering aluminium foil outside the power injection to avoid the influence of light, oxygen and vapor on the drug through non PVC composite membrane. It is easy to be transported and handled and can get over the danger of drug failure due to the middle weak seal crack by extrusion of external force in the production, storage and transportation of double chambers.

Description

Promptly join transfusion flexible bag

Technical field

This utility model belongs to area of medical devices, particularly a kind of transfusion flexible bag of promptly joining.

Background technology

At present injectable powder or the lyophilized injectable powder of using clinically is that the sterile bulk drug powder is divided in the sterilized vial, will produce supporting diluent simultaneously or directly with finished product transfusion dilution.After medical personnel will extract diluent with disposable syringe during application, inject in the injectable powder vial, shake vial and make the powder dissolving, and then in vial, extract dissolved medicinal liquid, be added to and give patient's infusion in the infusion bottle behind the mix homogeneously with syringe.

Traditional mode of production manufacturing cost height, energy consumption is big, and vial is a fragile article, and transportation is inconvenient, difficult, the cross-contamination and the mistake of making up a prescription easily take place in complex operation when medical personnel use during preparation, cause the medication unsafe factor.

Summary of the invention

The purpose of this utility model provides a kind of easy to use, simplifies medical personnel's operation during use, avoids cross-contamination, joins transfusion flexible bag safely and effectively.

For achieving the above object, solution of the present utility model is: a kind of transfusion flexible bag of promptly joining, comprise a soft bag, one end of soft bag is provided with out liquid interface, soft bag bottom is provided with and hangs bag mouth and locating hole, described soft bag is divided into three chambers in upper, middle and lower, is provided with weak joint seal between the adjacent chamber, describedly goes out liquid interface top and is connected with composite cover.

Described upward chamber is a liquid chamber, interior fill transfusion liquid or diluent, middle chamber is the baffle safety chamber, be subjected to the external force extruding to force the weak joint seal of first between two chambers to be squeezed when opening in case go up indoor liquid, volume increasing behind the chamber during liquid enters, pressure reduces, and guarantees that liquid is difficult to enter down the chamber, plays the baffle safety effect; Following chamber is a powder chamber, dress small-volume injection or lyophilized injectable powder, and soft bag periphery is strong edge sealing.

Transfusion flexible bag is promptly joined in disposable use of the present utility model, makes by non-PVC composite membrane, and disposable use, preparating liquid under the sealing situation uses relieved more safely.Some is to the medicine of light, oxygen and water vapor sensitive; can outside injectable powder, cover aluminium foil medicine is protected, avoid light, oxygen and steam to see through non-PVC composite membrane and the influence of medicine is easy to transport, carries and overcome that dual cavity is subjected to the external force extruding in production, storage, transportation and middle weak joint seal cracking and make the danger of loss of drug potency.

Description of drawings:

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

Fig. 2 is the cutaway view of composite cover among this utility model embodiment.

Specific embodiments:

As Fig. 1, shown in Figure 2, this promptly joins transfusion flexible bag, comprise a soft bag 3, one end of soft bag 3 is provided with out liquid interface 2, soft bag 3 bottoms are provided with and hang bag mouth 9 and locating hole 10, it is characterized in that: described soft bag 3 is divided into, in, following three chambers, be provided with weak joint seal between the adjacent chamber, separated by the first weak joint seal 5 between last chamber 4 and the middle chamber 6, separated by the second weak joint seal 7 between middle chamber 6 and the following chamber 8, described chamber 4 interior fill transfusion liquid or the diluent of going up, middle chamber 6 is the baffle safety chamber, in case the liquid of going up in the chamber 4 are subjected to the external force extruding to force weak joint seal 5 quilts of first between two chambers to squeeze when opening, chamber 6 back volumes strengthened during liquid entered, pressure reduces, and guarantees that liquid is difficult to enter down chamber 8, plays the baffle safety effect; Dress small-volume injection or lyophilized injectable powder in the following chamber 8, soft bag periphery is strong edge sealing.Go out liquid interface 2 tops and be connected with composite cover 1 described, described composite cover 1 is made up of with inner cap 12 3 parts enclosing cover 13, butyl rubber pad 11, described butyl rubber pad 11 with go out liquid interface 2 and be connected, be connected to inner cap 12 in butyl rubber pad 11 and the outer cover that goes out liquid interface 2, inner cap 12 outer cover are connected to enclosing cover 13.

Promptly join transfusion flexible bag when using, check relevant item on request, after the passed examination, firmly chamber 4 is gone up in extruding, make liquid in the chamber 4 be squeezed the back squeeze open first a little less than joint seal 5, liquid enters baffle safety chamber 6, makes chamber 4 become a chamber in baffle safety chamber 6.Push liquid again, make to squeeze behind the liquid pressurized and open the second weak joint seal 7, liquid enters down chamber 8, waves to make liquid fully dissolve powder, treats that powder dissolves fully, after the liquid clarity test is qualified, transfusion device is pricked lead to composite cover, can carry out intravenous drip.
