Abstract
The utility model relates to a medical double-plastic infusion pump, which comprises a liquid storage bag, a liquid outlet and an air outlet. The liquid storage is provided with double plastic films; the inner layer is a liquid protecting layer and the outer layer is an air pressure protecting layer. A liquid inlet and an air outlet are respectively arranged on the liquid storage bag. An inflating opening is arranged on the air pressure layer. The air pressure in the air pressure layer provides motive power for the flowing of the storage liquid. The utility model has simple and novel structure. Because the utility model adopts the air pressure as the transfusion motive power, the placing position of the liquid transfusion bag is unlimited; the trouble that the transfusion can be carried out only by the pressure difference produced by hanging the transfusion bag at a transfusion frame is saved; the utility model is easy and safe when in use.
Description
Technical field
This utility model relates to a kind of device of medical plastic thin film transfusion, and particularly a kind of medical double-plastic infusion pump is the innovation to the conventional medical infusion pump.
Background technology
Medical infusion apparatus is of a great variety at present, for example general hospital uses homemade MR-508 infusion pump and HX-801A multifunctional transfusion pump, above-mentioned infusion set, the function of its pump seldom, only play the effect of trace control transfusion, still infusion bottle or bag will be hung on the drip stand during transfusion, by improving the pressure dropping liquid that highly produces, volume is bigger, uses little convenience.And this class transfusion pump structure is complicated, and the electronic component of use is more, installs, debugs complicated.The electronic microsyringe that also has a kind of hospital to use, its volume is bigger, external AC220 volt power supply.Therefore, it is a kind of both convenient, simple to design, and reliable again, safety have positive realistic meaning without the infusion pump of external power.
Summary of the invention
The purpose of this utility model provides a kind of medical double-plastic infusion pump, it adopts double-plastic layer pump body structure, inject transfusion at internal layer, charge into the gas of certain pressure at outer and interior interlayer, by the gas pressure in the barosphere, transfusion in the liquid storing bag is input in patient's body along dropper, thereby reaches easy to operate, the transfusion purpose of safety.
Technical solution adopted in the utility model:
A kind of medical double-plastic infusion pump; comprise liquid storing bag, liquid outlet, gas discharge outlet; be characterized in that liquid storing bag establishes bilayer (nexine and skin) plastic film layers; its nexine is the liquid protective layer; skin is the air pressure protective layer; in the cavity of nexine, annotate to contain transfusion, nexine and outside charge into the gas of certain pressure in the barosphere of interlayer.Be respectively equipped with liquid injection port and gas discharge outlet in the liquid storing bag both sides, on the barosphere between liquid protective layer (nexine) and air pressure protective layer (skin), be provided with inflation inlet.Inflation inlet can be located at the upside or the lower side of liquid storing bag.This utility model is operation like this: the transfusion that will infuse injects in the nexine cavity of transfusion bag along liquid injection port, open gas discharge outlet simultaneously, make gas discharge in the transfusion bag nexine cavity, then by the barosphere inflation of inflation inlet to liquid storing bag, make the liquid that leaves nexine in be subjected to certain air pressure, the interface of transfusion drip tube is connected on the liquid injection port of liquid storing bag.In the time will infusing, the transfusion in the starting switch, liquid storing bag is just slowly extruded by micro actuator under the barosphere air pressure, is input in patient's body.Because adopt air pressure as transfusion power, transfusion bag is placed unrestricted, has just saved transfusion bag and will hang over the trouble that could produce pressure differential on the drip stand, uses easily, does not also take the place.
Compare with traditional infusion pump, this utility model novel structure, it adopts double-plastic layer pump body structure, inject transfusion at nexine, nexine with outside interlayer (being barosphere) charge into the air of certain pressure, by gas pressure in the barosphere, the liquid storage in the liquid storing bag is input in patient's body along dropper, thereby saves the trouble that transfusion bag will hang over drip stand or adopt electrodynamic pump.

The specific embodiment
Shown in Fig. 1-2, in Fig. 1 and Fig. 2, this utility model is a double-plastic layer pump body structure, and the liquid storing bag 1 of infusion pump is established the double-plastic layer, i.e. nexine 3 and outer 4, and nexine is the liquid protective layer, outerly is the gas shield layer.In nexine 3, inject transfusion, in nexine 3 and outer 4 s' barosphere 2, charge into the air of certain pressure, be respectively equipped with liquid injection port 5 and gas discharge outlet 6 in the liquid storing bag both sides, in barosphere, be provided with inflation inlet 7.During use, to infuse and inject in the nexine 3, open gas discharge outlet 6 simultaneously, the gas in the transfusion bag nexine is discharged by liquid injection port 5, by 2 inflations of the barosphere in 7 pairs of liquid storing bags of inflation inlet, make the transfusion that is contained in the nexine be subjected to certain air pressure then.During transfusion, dropper is connected on liquid injection port, the liquid in the liquid storing bag just under the barosphere air pressure by the extruding of micro actuator, import in a steady stream in patient's the body.
Claims (2)
1. a medical double-plastic infusion pump comprises transfusion bag, liquid outlet, gas discharge outlet, it is characterized in that liquid storing bag (1) establishes the double-plastic layer, and both nexine (3) and outer (4) were barosphere (2) between nexine (3) and skin (4); Be respectively equipped with liquid injection port (5) and gas discharge outlet (6) in liquid storing bag (1) both sides, on barosphere (2), be provided with inflation inlet (7).
2. follow according to the described medical double-plastic infusion pump of claim 1, it is characterized in that the inflation inlet (7) on the barosphere can be located at the upside or the downside of liquid storing bag (1).
