Description

The anti-pollution disposable transfusion device of band drug feeding device

This utility model relates to medical apparatus, particularly the anti-pollution disposable transfusion device of the band drug feeding device that uses during venous transfusion.

Venous transfusion is treatment and prophylactic basic mode, and often be multiple medication combined application, at present clinical before transfusion during feeding operations, usually earlier in liquid bottles, extract certain liq out with syringe, subsequently it is injected respectively in the injectable powder medicine bottle, after the dissolving of vibration medicated powder (the aqueous injection operation together down), again the medicine bottle inner liquid medicine is extracted out with syringe, at last it is injected in the liquid bottles this molten medicine, dosing method, not only loaded down with trivial details, effort, and be exposed to the external world because of the syringe needle long period, and puncture medicine bottle repeatedly, repeatedly contact medicinal liquid, therefore on suitable degree, increased the liquid medicine contamination probability; In addition, existing used disposable transfusion device, its air intake structure is very unreasonable, because of the bottle pin is lacked (the air inlet duct is opened on its tip), so air inlet is positioned at (this moment, liquid bottles was inversion) below the medicinal liquid plane all the time in infusion process, because of pressure of the inside of a bottle lowers gradually, outside air is not open close to enter the bottle bottom by filter through medicinal liquid, this process equals with medicinal liquid the air that enters to be filtered once more, will certainly make a part of polluter viscous that wherein contains or be dissolved in the medicinal liquid, this type of pollutes Shang Jinwei and is much accounted of.Chinese patent discloses a kind of electronic imbibition dispensation apparatus and a kind of medicine dissolving device respectively No. 98221398.0 and 99215569.X number in the recent period, the former is medical attraction or transfer liquid device, volume is very big, be only applicable to the dosing of aqueous injection medicine, latter's technology is to be communicated with two-tube syringe needle with two plastic flexible pipes, dead point liquid bottle is in parallel with powder injection bottle, utilize the suction of syringe to suck liquid, inject in the liquid bottles after vibration makes the medicated powder dissolving, above technology has improved work efficiency to a certain extent again, reduced opportunities for contamination, but dosing is single separately because of it, and operation is still more loaded down with trivial details, does not fundamentally address the above problem.

Order of the present utility model ground is: improve at the problem that prior art exists, design provides a kind of simple in structure, and volume is little, dependable performance, anti-pollution, high efficiency collects molten medicine, dosing, interim administration is the anti-pollution disposable transfusion device of the band drug feeding device of one.

This utility model is achieved by following manner: a kind of anti-pollution disposable transfusion device with drug feeding device, comprise transfusion device 1 and plug together the drug feeding device 2 that connects with bolt, well format with its top, it is characterized in that: the three-way valve syringe needle 10 that drug feeding device 2 is installed by syringe 13 and its front end with side opening post 11, side opening post 11 is provided with the chemical feed pipe 6 that far-end is hole bolt 9 devices, shown in Fig. 1 .2.4,1 bottle of pin 4 lower end of transfusion device are furnished with band filter 7 and possess the chemical feed pipe 6 structures composition of socket 8 devices of blocking cap, shown in Fig. 1 .3.4.

Said syringe 13 can be three ring handles, 14 structures, shown in Fig. 1 .5.

Said three-way valve syringe needle 10 can be a double hole channel, and valve ∩ type is regulated 12, three opening and closing structures of swing handle, shown in Fig. 1 .2.

Said bottle pin 4 has suitable length (8-16 centimetre), air inlet duct 3 and dosing duct 5 respectively by and be opened on the structure on its tip and top, shown in Fig. 1 .3.

When present technique is used, valve swing handle 12 is transferred behind the full application position, bottle pin 4 and three-way valve syringe needle 10 are inserted (injectable powder) in liquid bottles and the medicine bottle respectively, suction repeatedly, bolus infusion device 13, after the liquid that medicated powder sucks in liquid bottles dashes and washs dissolving, through chemical feed pipe 6 pressure injections in liquid bottles, as add the aqueous injection medicine, after available swing handle 12 is closed chemical feed pipe 6 paths, medicinal liquid is drawn in the syringe 13, regulates swing handle 12 then and close the syringe needle path, bolus infusion device 13, medicinal liquid flows in the liquid bottles (bigger as amount of liquid medicine, syringe needle can be remained in the medicine bottle, finish through the said procedure gradation) through chemical feed pipe 6, after feeding operations finishes, drug feeding device 2 chemical feed pipes 6 are pulled up in hole bolt 9 places, the blocking cap of closing transfusion device 1 side tube for transfusion socket 8, waiting to be equipped with thus, mouth adds medicinal temporarily.

This utility model is compared with prior art, has following characteristics:

Dependable performance, prevent to pollute: this utensil adopts a closed conduit system and a bottle pin air inlet 3 to be higher than the fluid level structure, and operation sequence is few, and it is short that syringe needle 10 exposes the time, do not need repeated localised puncture, so realized the sterile working substantially.

2. applied widely: the molten medicine of present technique collection, dosing are one, medicine to different dosage form is all suitable fully, (traditional method is through the bottle cap sucking-off with syringe as need reduce in the infusion bottle amount of liquid because of the treatment factor time, or transfusion device unpluged, emitted excess liquid through tube for transfusion by needle tubing top seam), behind the scalable three-way valve 12, extract out smoothly with syringe 13, in addition, chemical feed pipe socket 8 can be made the usefulness of interim dosing.

3. use simple and convenient, saving medicine: syringe 13 of the present utility model adopts three ring handles, 14 structures, be fit to singlehanded flexible operating, molten medicine, dosing overall process can once be finished, the operation time and effect on (after the present feeding operations, have more medicinal liquid to leave in the medicine bottle) obvious improvement has all been arranged, therefore improved work efficiency greatly.

4. cost is low: this utensil is because of simple in structure, big part device is plastic material (containing three-way valve), so its cost lower (being equivalent to existing transfusion device+syringe cost), also because of having reduced packing (adopting an entire package), reduce environmental pollution, therefore all have more reality and practical significance from every side for our such populous nation.
