Abstract

The utility model provides a germfree inner-film covering transfusion bottle, which consists of a outer liquid bottle and a germfree inner-film liquid bag; the latter is covered inside of the former; an outtake of the germfree inner-film liquid bag is fixed on the inner side of the bottle mouth of the outer liquid bottle. The bottom surface of the outer liquid bottle is concave; a discharge valve is arranged on the concave bottom. The transfusion bottle with the structure can guarantee the germfree situation for the drug liquid from the outside air contact in the whole transfusion process, so as to thoroughly solve the second-pollution for the drug liquid because of the infusion of the air in the transfusion prices. The device can guarantee the safety and sanitation for the patient in the transfusion process and decrease the whole cost for the transfusion bottle.

Description

Aseptic inner membrance suit infusion bottle

Technical field:

This utility model belongs to area of medical devices, is specifically related to a kind of aseptic inner membrance suit infusion bottle.

Background technology:

At present, a lot of diseases all need to carry out infusion treatment, and now general medicinal liquid is that employing is packed or bottled.In order to prevent that the medicinal liquid packing material from being utilized once more by the lawless person, country's mandatory provision infusion vessel is necessary for disposable container.Existing transfusion device generally is single bottle of aseptic packaging, is inserted with tube for transfusion and air intake duct in vessel port in use, and tube for transfusion just is gnotobasis for the patient carries the pipeline inside of liquid; Next end of air inlet pipe one end insertion vessel level is connected with outside air like this can the feasible process that can finish transfusion of balance inner and outer air pressure.Outside air enters in the medicinal liquid by air inlet pipe, accompanying fine particle will enter medicinal liquid and then enter human body in the air like this, studies show that content of molds in the general hospital air unit volume is dozens or even hundreds of a times of outdoor air, so many pathogenic bacterias are with the not treated human body that directly enters of medicinal liquid, the air inlet pipe of transfusion device just becomes the express passway that pathogenic bacteria enters human body, very likely cause on patient's disease and add disease, also may cause simultaneously the quick propagation of infectious disease, diameter owing to the thinnest blood capillary of human body has only the 4-7 micron simultaneously, the contaminant particles diameter that enters human body is again greater than it, this just is easy to cause the obstruction of blood capillary, thereby cause body part generation blood supply insufficiency, produce edema and inflammation.Existing transfusion device is in order to address this problem generally air filter on adding on the air inlet pipe, though filtered out the bigger impurity of some diameters so to a certain extent, but can't filter out virus and bacteria and small impurity, therefore still can't thoroughly address this problem.

Summary of the invention

At the deficiencies in the prior art, this utility model provides a kind of aseptic inner membrance suit infusion bottle, has adopted double-decker to avoid the pollution of surrounding air for medicinal liquid.

Concrete technical scheme of the present utility model is: a kind of aseptic inner membrance suit infusion bottle, to form by outer liquid bottle and the aseptic inner membrance liquid bag that is sleeved on its inside, and the liquid outlet of aseptic inner membrance liquid bag is fixed on the bottleneck inboard of outer liquid bottle; On the outer liquid bottle vent valve is arranged.

Adopt the infusion bottle of this structure, medicinal liquid can be injected in the aseptic inner membrance liquid bag, after being full of medicinal liquid in the liquid bag liquid bag with outside the liquid bottle do not have the slit, so just made things convenient for the transportation of medicine that the leakage of medicinal liquid can not take place, when infusing, whole medicine bottle is inverted, from bottleneck, insert tube for transfusion, opening vent valve makes inner the connection with atmosphere of bottle infuse and will begin, aseptic inner membrance liquid bag can be followed the minimizing of liquid and dwindles gradually in the infusion process, guarantee not contact the aseptic condition that has kept medicinal liquid with the air in the external world at whole infusion process herb liquid, thereby the injection that does not need outside air thoroughly solved medicinal liquid in infusion process because air injects the secondary pollution problem that causes, guaranteed the safety and sanitation of patient's infusion process.

The bottom surface of outer liquid bottle is a spill, at the center of concave bottom surfaces vent valve is arranged, and the height of vent valve is less than the recessed degree of depth of bottle, and vent valve can not influence the stability of whole bottle when normal condition is placed like this, is convenient to depositing and transporting of medicine bottle.

But hook of suit on two of the bottom surface of liquid bottle bottle feet can directly hang over infusion bottle on the drip stand by this hook so in use outside, has made things convenient for operation of medical workers to link up with simultaneously also can secondary to use save resource; Owing to adopted the vent valve of bottle itself so need not re-use air intake duct, medical personnel needn't be changed dressings all need to repeat to plug air intake duct at every turn and reduced workload, also reduced the whole cost of infusion bottle.

The technical scheme of this design is not only applicable to the infusion bottle of glass material outer package, is applicable to the transfusion bag that adopts the plastic material outer package yet, and the aseptic inner membrance liquid bag of its inside is constant, can adapt to the production of different manufacturers and the needs of hospital like this.

Description of drawings

Structure cutaway view when Fig. 1 uses for this utility model;

1 is outer liquid bottle among the figure, and 2 is aseptic inner membrance liquid bag, and 3 is bottleneck, and 4 is vent valve, and 5 are the venting valve gap, and 6 is tube for transfusion.

The specific embodiment

Infusion bottle described in the utility model is as shown in Figure 1: a kind of aseptic inner membrance suit infusion bottle is made up of outer liquid bottle 1 and aseptic inner membrance liquid bag 2, and the liquid outlet of aseptic inner membrance liquid bag 2 is fixed on bottleneck 3 inboards of outer liquid bottle 1; The bottom surface of outer liquid bottle 1 is a spill, at the concave bottom surfaces center vent valve 4 is arranged, and the height of vent valve 4 is less than the recessed degree of depth of external bottle 1.

During use as shown in the figure: the reversal of the natural order of things of whole infusion bottle is on drip stand, tube for transfusion 6 is inserted into from bottleneck 3 in the aseptic inner membrance liquid bag 2, unpluging venting valve gap 5 makes the space in the outer liquid bottle 1 be communicated with atmosphere by vent valve 4, the transfusion beginning, follow the minimizing of bag interior liquid, aseptic inner membrance liquid bag 2 also dwindles the drippage that guarantees that the bag inner liquid medicine continues thereupon gradually, guarantees the sterile vacuum in the bag simultaneously.Regulate the dropleting speed of medicinal liquid by the flow control valve on the adjusting tube for transfusion.

Outer liquid bottle adopts medical plastic to make the means of deflation on it and can adopt medical plastic also can adopt the medical grade rubber manufacturing, and aseptic inner membrance liquid bag adopts the medical film of sterile workshop manufacturing to make.
