Abstract

The utility model relates to a decrement infusion device which comprises a disposable delivery tube and a delivery bottle. Both ends of the hose of the disposable delivery tube are connected with an exhaust needle head. The middle part of the hose is provided with water stop. An exhaust vent is arranged on the needle body of the needle head, and a filter screen is arranged on the bottom of the exhaust vent. The exhaust needle head on one end of the hose is inserted in a rubber stopper on the upper part of the delivery bottle with scales. The utility model has the advantages of convenient operation, medical liquid saving, aseptic operation, simple structure and low cost.

Description

Decrement infusion device

This utility model relates to novel infusion utensil---the decrement transfusion device that a kind of clinical medicine uses.

A large amount of at present common disposable transfusion devices that use mainly only are made up of conduit, a kettle, water, when carrying out transfusion operation, it are connected with infusion bottle, and medicinal liquid promptly enters patient's vein by a dropper and conduit etc.But the infusion bottle of standard is 500ml or 250ml dress at present, and considers for treatment clinically, only need 100～300ml to a lot of patients' a amount of infusion.When using general infusion set,, infuse again after having to outwell medicinal liquid unnecessary in the standard infusion bottle in order to obtain specific amount of infusion.This has just increased the chance of liquid medicine contamination, has not both met the requirement of sterile working, and operation is inconvenient again, has also wasted a large amount of medicinal liquids, and patient's both sides of hospital are brought loss.

Decrement transfusion device of the present utility model is just in order to overcome above-mentioned deficiency, and based on the sterile working, convenient transfusion and three targets of saving medicinal liquid design.

Above-mentioned purpose of the present utility model is realized by following technical scheme: this transfusion device comprises disposable separating tube and delivery flask, disposable separating tube only is made up of exhaust syringe needle, flexible pipe and water, flexible pipe is connected with the exhaust syringe needle sealed at both endsly, flexible pipe middle part cover water ends, open the steam vent of plug with holes on the needle body, the exhaust syringe needle that drainage screen, flexible pipe one end are equipped with in steam vent bottom inserts in the delivery flask of band scale on bottleneck band dosing hole, the bottle wall and the upper and lower opening rubber closure suitable for reading.

The utility model has the advantages that: this transfusion device can directly be connected with the standardization infusion bottle, can strictness carry out the sterile working, and can set various different amount of infusion, medicinal liquid in original infusion bottle is fully used, saved medicinal liquid, easy to use, reasonable in design, cost is low, production technology is simple and easy to do, helps promoting.

Concrete structure of the present utility model is provided by accompanying

drawing

1,2.

Fig. 1 is a decrement transfusion device overall structure sketch map;

Fig. 2 is a cone-shaped delivery flask structural representation.

Primary structure is among the figure: flexible pipe 1, exhaust syringe needle 2, water end 3, steam vent 4, stopple 5, drainage screen 6, delivery flask 7, dosing hole 8, rubber closure 9.

Below in conjunction with accompanying drawing this utility model is described in detail.

This decrement transfusion device structure mainly is made up of disposable separating tube and delivery flask two large divisions as shown in Figure 1.Disposable separating tube structure as shown in Figure 1.It is by a suitably long flexible pipe 1, is sealedly connected with two exhaust syringe needle 2 roots symmetrically at two ends, and the needle point of two syringe needles is outside, and the middle part of flexible pipe is with a water and ends 3, in order to open or to turn-off flowing of medicinal liquid.Respectively have a steam vent 4 on the needle body of two syringe needles, medicinal liquid is imported smoothly, stopple 5 is equipped with at the steam vent top, can open easily and close, and drainage screen 6 is equipped with in the steam vent bottom, in order to the dirt in the filtering bottle outer air.

Delivery flask 7 structures as shown in Figure 1, it is that up and down two ends all are provided with the graduated vessels of opening, two openings are all sealed with rubber closure 9.Have near the bottleneck of bottle top a plug with holes as medicine hole 8.Stopple is used for the dirt in the outer gas of isolation bottle.Open stopple during dosing in bottle, dosing finishes and covers stopple.It is easy to use that bottle also can be up big and down small bullet.Bottle can be made (being used for disposable use) by transparent plastic.

The principle of decrement transfusion device and using method

1. separatory---set and distribute the standard medicinal liquid of an amount of infusion.

The exhaust syringe needle of flexible pipe one end is inserted in the rubber closure on delivery flask top, and the another syringe needle inserts the standard infusion bottle.Open two steam vents and water and end, and the standard infusion bottle is raised, the standard medicinal liquid just flows into delivery flask by disposable separating tube.When the medicinal liquid liquid level arrives the graduation mark that sets, close and only cut off the water supply and the steam vent of standard infusion bottle one end.The separatory operation is promptly accused and is finished.

2. transfusion

An end that has general disposable infusion needle tubing now is inserted in the rubber closure of delivery flask bottom, and delivery flask is adjusted to suitable height.The other end with Transfusion needle pipe inserts patient's vein again, opens needle tubing water and only infuses.Owing to used existing disposable infusion needle tubing, not only reduced unnecessary loss, use also very convenient.

If, in the time of need in the standard medicinal liquid, adding other auxiliary medicinal liquid, can behind the separatory EO, open the dosing hole immediately for the consideration in the treatment, in delivery flask, add auxiliary medicinal liquid, close the dosing hole, carry out transfusion operation again.High-temperature sterilization, aseptic making, aseptic packaging all must be passed through in each surface of all parts of decrement transfusion device.

3. use one bottle of standard medicinal liquid repeatedly to infuse

There is an amount of infusion of a lot of transfusion operations to have only 100-300ml clinically, that have even littler.When the standard infusion bottle of selecting 500ml dress for use has been finished transfusion operation by the method for " 1 ", " 2 " after, will remain a part of medicinal liquid in the standard infusion bottle.But because the aseptic buffer action of decrement transfusion device, this part medicinal liquid will be not contaminated, thereby can repeatedly use.This just makes one bottle of standard medicinal liquid repeatedly infuse becomes possibility.Thereby when repeatedly infusing, only need in delivery flask, divide to go into the residue medicinal liquid in the standard infusion bottle again, up to using until exhausted.

Claims

1, a kind of decrement transfusion device, it is characterized in that comprising disposable separating tube and delivery flask, disposable separating tube is by the exhaust syringe needle, flexible pipe and water end to be formed, the flexible pipe two ends are sealedly connected with two exhaust syringe needle roots symmetrically, the needle point of two syringe needles is outside, the flexible pipe middle part is with water and ends, have steam vent on the needle body of two syringe needles, stopple is equipped with at the steam vent top, drainage screen is equipped with in the steam vent bottom, on the delivery flask, following two ends all are provided with opening, are with scale on the bottle wall, and two openings all seal with rubber closure, have the dosing hole of a plug with holes near the bottleneck of bottle top, during separatory, the exhaust syringe needle of flexible pipe one end is inserted in the rubber closure on delivery flask top, constitute a decrement transfusion device.

2, decrement transfusion device as claimed in claim 1 is characterized in that the bottle of delivery flask is shaped as up big and down small bullet.
