Abstract
The utility model relates to a disposable bag type infusion device with a three-way valve. The disposable bag type infusion device with the three-way valve includes puncture devices, liquid dispensing bags, the three-way valve and an infusion needle, wherein each puncture device is connected with a liquid inlet end of the corresponding liquid dispensing bag, the three-way valve is connected with liquid outlet ends of the liquid dispensing bags through first hoses, and an outlet of the three-way valve is communicated with the infusion needle. An original three-way piece or T joint is replaced by the three-way valve, so that when the entry of liquid medicine needs to be stopped in case of improper operations, the three-way valve can be closed by direct operations, which achieves convenience and handiness in operation and greatly reduces the risk of accidents. Therefore, the infusion device has the advantages of convenience in operation, low cost, wide application range, and the like.
Description
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of disposable use bag transfusion system with three-way valve.
Background technology
Disposable two pair bag transfusion devices of inserting have become at present the clinically transfusion device of very general use, this class transfusion device mainly overcomes original transfusion device can not thoroughly be separated two kinds of different medicinal liquids, drug reaction easily occurs in medicinal liquid, medical worker's the large deficiency of the workload of changing dressings.This class transfusion device mainly is comprised of perforator, flow regulator, separatory bag, plain filter and transfusion needle.But the deficiency of this class transfusion device is to adopt tee T or trident to be connected between separatory bag and dropping funnel, if in case occur to slip up in the time of to stop at once the medicinal liquid input, need flow regulator to regulate, like this operating time relatively long quick not for a long time, thereby have influence on patient.Therefore need to be improved the filtering accuracy of existing two slotting single bag of transfusion devices to medicinal liquid, thereby patient's health is protected.
The utility model content
The purpose of this utility model is exactly in order to overcome the deficiency of transfusion device, and a kind of disposable use bag transfusion system with three-way valve simple in structure, convenient to operation is provided.
The technical scheme that this utility model adopts to achieve these goals is as follows: a kind of disposable use bag transfusion system with three-way valve, it is characterized in that: comprise perforator, separatory bag, three-way valve and transfusion needle, described perforator is connected to the liquid feeding end of separatory bag, described three-way valve is connected with the liquid outlet of separatory bag by the first flexible pipe, and the outlet of three-way valve is communicated with transfusion needle.
A kind of disposable use bag transfusion system with three-way valve described in this utility model characterized by further comprising liquid medicine filter, and described liquid medicine filter is between three-way valve and transfusion needle.
The disposable use bag transfusion system with three-way valve described in this utility model characterized by further comprising the first switch that enters separatory bag medicinal liquid flow for control, and the first switch is arranged on the first flexible pipe and between separatory bag and perforator.
The disposable use bag transfusion system with three-way valve described in this utility model characterized by further comprising second switch, itself and between three-way valve and liquid medicine filter.
The disposable use bag transfusion system with three-way valve described in this utility model characterized by further comprising dropping funnel, and this dropping funnel is between three-way valve and second switch.
The disposable use bag transfusion system with three-way valve described in this utility model is characterized in that described three-way valve is installed on the inlet of dropping funnel or the inlet by hose connection dropping funnel.
The disposable use bag transfusion system with three-way valve described in this utility model is characterized in that also being provided be used to adding medicinal bipass on the described separatory bag, is stamped the tack rubber cap on this bipass.
The disposable use bag transfusion system with three-way valve described in this utility model is characterized in that also being connected on the perforator air filter.
This utility model changes original three-way piece or trident into three-way valve, thereby when needing to stop medicinal liquid to enter when occuring to slip up, only need the straightforward manipulation three-way valve, can close, convenient to operation, significantly reduced the risk of accident, so that this transfusion device has is easy to operate, cost is low, the advantage such as applied widely.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1-perforator, 2-the first switch, 3-separatory bag, 4-three-way valve, 5-the first flexible pipe, 6-liquid medicine filter, 7-transfusion needle, 8-air filter, 9-second switch, 10-dropping funnel, 11-bipass.
The specific embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is described further, but this utility model is not limited in following embodiment.
As shown in Figure 1: have the disposable use bag transfusion system of three-way valve, it comprises perforator 1, the first switch 2, separatory bag 3, three-way valve 4, liquid medicine filter 6, transfusion needle 7 and second switch 9, is integral by hose connection therebetween.Aforesaid the first switch 2 and second switch 9 mainly are in order to regulate the flow of medicinal liquid, to play simultaneously the effect of switch, therefore can adopting pipe clamp, flow regulator etc. to have the device of regulating fluid flow when actual production and all can.Wherein perforator can be divided into bottle plug puncture unit and disk perforator, and wherein bottle plug puncture unit is provided with air filter 8.Concrete is that three-way valve 4 is connected with separatory bag 3 by the first flexible pipe 5, and the outlet of three-way valve 4 is communicated with dropping funnel 10, perhaps three-way valve is directly installed on dropping funnel upper end (inlet).Then the first switch 2 is arranged on the first flexible pipe 5 and between separatory bag 3 and two perforators 1.Transfusion needle 7 is by hose connection to liquid medicine filter, then be connected dropping funnel 10 and second switch 9 on the flexible pipe between liquid medicine filter 6 and the three-way valve 3, and second switch 9 is between liquid medicine filter 6 and dropping funnel 10 again.When operating, carry out dosing according to practical situation for convenient, therefore on separatory bag 3, be provided for again adding medicinal bipass 11, and be stamped the tack rubber cap at this bipass 11.In order conveniently to hang up the separatory bag, this utility model is also set up a link at separatory bag 3.In order to make things convenient for medical personnel to watch at any time the medicinal liquid operating position, can also scale value be set at the bag of separatory bag, so more intuitively judge accurately the operating position of medicinal liquid.This utility model also also is provided with respectively between separatory bag 3 and three-way valve 4, is used for regulating feed liquor amount and the feed liquor speed of medicinal liquid.
A perforator in this utility model, first switch and a separatory bag just form one group of feed liquor mechanism, in needs of production, can increase according to actual needs the quantity of feed liquor mechanism in right amount, get final product thereby accordingly three-way valve is changed to multiple-way valve.
This utility model is not limited in above-mentioned embodiment, replace or simple increase and decrease so those skilled in the art can be equal to according to technique scheme, and the technical scheme that can derive through creative work is all because belonging within the technical scope of the present utility model.
