Abstract

The utility model relates to positive pressure leak detection high-capacity soft bag infusion comprising liquid medicine used for infusion, outer-layer packaging for packaging the liquid medicine and an infusion device, wherein the infusion device is welded with the packaging together, the packaging consists of at least an inner layer of packaging and an outer layer of packaging, namely an inner packaging bag and an outer protective sleeve, and a vacuum structure is arranged between the inner packaging bag and the outer protective sleeve. As pressure difference produced by the vacuum structure is enough to break down tension on the surface of the liquid medicine in the packaging bag, more liquid medicine passes through a packaging body more rapidly, and obvious water mist or droplets visible to naked eyes are formed between the packaging bag and the protective sleeve, therefore, in detection, the soft bag infusion with micro-leakage can be excluded, so as to protect the life and health of people.

Description

A kind of malleation leak detection high capacity soft bag infusion

Technical field

This utility model relates to a kind of medical soft bag infusion.

Background technology

China is the big country that the high capacity soft bag infusion uses, in a lot of medical schemes, all to use soft bag infusion, in medical procedure, the high capacity soft bag infusion can play additional body fluid, regulates electrolyte or nutrient substance is provided, but the high capacity soft bag infusion is directly to enter human vein blood, so prescription is high especially.Safety is that production of high capacity soft bag infusion and use especially need to pay attention to.The high capacity soft bag infusion from the production of packed in flexible pouchy material, packaging process, to medicinal liquid production, fill, stock, again to the use of medical space, all taked strict safety measure, strive patient not being produced harm.

But owing to technology and production management's reason, the high capacity soft bag infusion of China's production at present, can not accomplish that dispatching from the factory of product 100% is qualified, promptly use some high capacity soft bag infusion product qualified when dispatching from the factory, also very likely potential safety problem, former thereby occur because of moving after dispatching from the factory, environmental change etc.

Safety problem for the high capacity soft bag infusion, wherein one is the contaminated problem of bag inner liquid medicine, the high capacity soft bag infusion is in the pouring process of medicinal liquid, may be because at the edge of packaging material welding quality or other unpredictable elements, can cause the hole that capillary on package body, occurs, very fine of this hole, to such an extent as to after liquid medicine filling, because the viscosity of medicinal liquid itself, all do not leak out immediately, have up to use in the medical space, all do not leak out, but the existence in capillary hole has coupled together the medicinal liquid in the packaging bag and the external world, this has opened Yishanmen for the antibacterial in the surrounding beyond doubt, and antibacterial can be entered in the medicinal liquid.Capillary hole naked eyes are invisible, and medicinal liquid seepage naked eyes are invisible, get rid of this transfusion that may produce pollution so be difficult to way.

The medicinal liquid that has produced germ contamination exists great potential safety hazard, in case use on one's body the patient, can produce serious clinical adverse, especially serious, can cause the patient death phenomenon, at present in the soft bag infusion that is dispatched from the factory in the whole nation, have up to 0.5 ‰ soft bag infusions to have the capillary hole and can't detect.

The utility model content

Healthy and safe in order to guarantee people's life, further eliminate medical safety hidden danger, being safety in the production of infusing to each link of using provides safeguard, this utility model provides a kind of malleation leak detection high capacity soft bag infusion, comprises the medicinal liquid of the usefulness of infusing, the outer packaging of encapsulation medicinal liquid, and infusion device, infusion device and packing weld together, and described packing is made of inside and outside two-layer at least packing, i.e. packing inside bag and outer jointing jacket; It between described packing inside bag and the outer jointing jacket vacuum structure.

This utility model comprises wrapper and layer protective layer at least; its medicinal liquid is packaged in the packaging bag; protective sleeve is at outermost; between packaging bag and protective sleeve, be set to vacuum structure; make interior its pressure of medicinal liquid of packaging bag greater than the outer pressure of packaging bag; comparatively speaking, the medicinal liquid in the packaging bag constitutes the outer positive pressure of packaging bag, and is much higher than normal atmosphere (An).This positive pressure; be enough to break the tension force on packaging bag inner liquid medicine surface; make the quicker package body that passes through more of medicinal liquid; and between packaging bag and protective sleeve, form the passable water smoke clearly or the globule of naked eyes; when detecting; just this soft bag infusion that has produced little leakage can be excluded, protect the people's life and health.

The specific embodiment

Below in conjunction with drawings and Examples this utility model is further specified.

This utility model provides a kind of malleation leak detection high capacity soft bag infusion, on structure, this utility model comprises the medicinal liquid 1 of the usefulness of infusing, the outer packaging of encapsulation medicinal liquid, and infusion device 2, infusion device 2 and packing weld together, and described packing is made of inside and outside two-layer at least packing, i.e. packing inside bag 4 and outer jointing jacket 3; Be vacuum structure between described packing inside bag 4 and the outer jointing jacket 3.

Be to carry out the fill of medicinal liquid in the packaging material, and weld infusion device at production link of the present utility model; after welding is good, packaging bag is inserted in the protective sleeve seal protection cover; and between protective sleeve and packaging bag extracting vacuum, its relative vacuum degree is-0.8.After extracting vacuum, carry out the overall disinfection sterilization once more.

Detection leakage mode of the present utility model is as follows:

By after producing soft bag infusion with upper type, with its warehouse-in, place storehouse more than 20 days or 20 days, during this period of time, can allow potential leakage packing quicken to form leakage, and between packaging bag and protective sleeve, form the obvious visible water smoke or the globule; Then from for taking out the storehouse, soft bag infusion placed to detect carry out naked eyes under the lamp and detect, and pick out leakage product.

In conjunction with the accompanying drawings the specific embodiment of the present utility model has been carried out exemplary description above, obviously this utility model is not limited thereto, and the various remodeling that carry out in this utility model scope all do not exceed protection domain of the present utility model.

Claims

1. malleation leak detection high capacity soft bag infusion, the medicinal liquid (1) that comprises the usefulness of infusing, the outer packaging of encapsulation medicinal liquid, and infusion device (2), infusion device (2) and packing weld together, it is characterized in that described packing is made of inside and outside two-layer at least packing, i.e. packing inside bag (4) and outer jointing jacket (3); Between described packing inside bag (4) and the outer jointing jacket (3) is vacuum structure.
