Abstract
The utility model discloses a dual-head valve type three-way infusion device which comprises a valve type tee joint. The valve type tee joint comprises two liquid inlets and a liquid outlet, wherein the two liquid inlets are connected with a first bottle plug puncturing device and a second bottle plug puncturing device through infusion pipes respectively, and the liquid outlet is sequentially connected with a Murphy pipe, a flow adjuster and an injector through infusion pipes. The problem that in the past, liquid needs to be frequently replaced during infusion, and a liquid bottle needs to be replaced by a next liquid bottle on time and in time after liquid is completely infused is solved; especially, during liquid replacing rush hours, liquid in the endemic area is placed on a treatment trolley and pushed into wards for replacement in a concentrated mode, nurses can less frequently go in and out of therapy rooms for medicine taking, patients or relations can automatically replace liquid by operating a three-way valve, and therefore labor intensity of nurses is greatly lowered, work efficiency is improved, and meanwhile the phenomenon that the patients feel panic and dissatisfied when liquid can not be replaced in time is avoided.

Detailed description of the invention
Describe embodiment of the present utility model below in detail, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has the element of identical or similar functions from start to finish.Be exemplary below by the embodiment being described with reference to the drawings, only for explaining this utility model, and can not be interpreted as restriction of the present utility model.
Describe according to a kind of Double-head valve formula Three-way transfusion system of this utility model embodiment below with reference to Fig. 1-8, comprise the first bottle plug puncture unit 1, the first bottle plug puncture unit 2, handle 3, cock 4, valve shell 5, Murphy tube 6, flow regulator 7, injection member 8 and tube for transfusion 9.
Valve type three-way comprises two liquid inlets and a liquid outlet 12, described two liquid inlets are the first liquid inlet 10 and the second liquid inlet 11, the first liquid inlet 10 is connected the first bottle plug puncture unit 1 and the second bottle plug puncture unit 2 by tube for transfusion 9 respectively with the second liquid inlet 11, and described liquid outlet 12 connects Murphy tube 6, flow regulator 7 and injection member 8 successively by tube for transfusion 9.
According to a kind of Double-head valve formula Three-way transfusion system of this utility model embodiment, it is by arranging valve type three-way, makes patient or the family members can self-changeable liquid, and can realize by a valve, easy and simple to handle, reduce nursing staff's working strength, improve work efficiency.
Particularly, described valve type three-way is cock type three-way valve.Hence one can see that, adopts the cock type three-way valve adjust flux of being more convenient for.
According to the present embodiment example, cock type three-way valve comprises valve shell 5 and cock 4, and described liquid inlet and liquid outlet 12 are located on described valve shell 5, described cock 4 is circular, be closely pressed together in valve shell 5, in cock 4, be provided with fluid path, described cock 4 outer ends are provided with handle 3.A kind of structure of durable cock type three-way valve is provided thus, can be cost-saving, raise labour efficiency.
Described the first liquid inlet 10 and the second liquid inlet 11 are located at the upper end of described valve shell 5 and are and be symmetrical set, and described liquid outlet 12 is located at the positive lower end of described valve shell 5.Make thus the design of first, second liquid inlet 11 and liquid outlet 12 more reasonable.
As further improvement of this embodiment, described fluid path comprises the first path 13 and the alternate path 14 that is connected described liquid outlet 12 that connect described the first liquid inlet 10 or the second liquid inlet 11, the first path 13 and alternate path 14 are connected, in the time that the first path 13 is communicated with the first liquid inlet 10 or the second liquid inlet 11, alternate path 14 is all connected with liquid outlet 12.In the time of rotation cock 4, alternate path 14 is connected with liquid outlet 12 all the time.In addition, the first path 13 is identical with the width of the first liquid inlet 10 and the second liquid inlet 11, to make, under prerequisite that liquid smoothness flows down, to reduce the size of cavity, increases the fastness of cock 4.Described alternate path 14 is more than or equal to the width at valve shell 5 and cock 4 contact surface places between the first liquid inlet 10 and the second liquid inlet 11 at the width between valve shell 5 and cock 4 contact surfaces.This shows, alternate path 14 is one, instead of be divided into two paths (when two paths, when rotation makes the first path 13 be communicated with two different liquid inlets, make two paths be communicated with respectively liquid outlet 12), can avoid like this liquid to store up and stay in alternate path 14, increase waste, cause what is more cross-contamination.In addition, preferred, alternate path 14 is arc, can reduce like this volume of fluid path, to increase the fastness of cock 4.Described arc height is the height of 1/3 cock, provides so rational fluid path structure, and when the arc left and right sides is contacted with liquid outlet 12, circulation passage keeps certain space, so that liquid smoothness flows down.
Handle 3 and the first path 13 are in same angle and be parallel to each other.Grasp the rotation degree of fluid path in rotation with this convenient operation person.In addition, as shown in Figure 8, cock 4 is cylinder prismatoid (near the large truncated cone-shaped of handle 3 one sides), is closely pressed together in valve shell 5, and the collar extension diameter of valve shell 5 is slightly a little bit smaller, can not drop out with cock 4 after the tight pressing of cock 4.
Nurse is during to patient infusion: respectively the first bottle plug puncture unit 1 and the second bottle plug puncture unit 2 are thrust in each liquid bottle stopper, by handle 3 axial-rotation cocks 4, fluid path first liquid inlet 10 that is connected the first bottle plug puncture unit 1 with valve shell 5 upper ends suitable for reading of cock 4 communicates, simultaneously also close valve shell 5 upper ends and connected the second liquid inlet 11 of the second bottle plug puncture unit 2, the end opening of abnormity fluid path communicates with the liquid outlet 12 that valve shell 5 lower ends are connected Murphy tube 6, liquid is unobstructed the flowing down of energy just, after the interior gas of emptying tube for transfusion 9, just can be to venous patient puncture transfusion.Be totally lost after first bottle of liquid, rotate cock 4 by handle 3, the second liquid inlet 11 that suitable for reading and valve shell 5 upper ends of the special-shaped fluid path of cock 4 are connected the second bottle plug puncture unit 2 communicates, simultaneously also close valve shell 5 upper ends and connected the first liquid inlet 10 of the first bottle plug puncture unit 1, the end opening of abnormity fluid path communicates with the liquid outlet 12 that valve shell 5 lower ends are connected Murphy tube 6, and liquid just can unobstructed flowing down.First bottle of liquid pulls out empty bottle after being totally lost, and changes the 3rd bottle of liquid and is connected with the first bottle plug puncture unit 1, and before being totally lost to second bottle of liquid, during this period of time, changing any time can.
Although illustrated and described embodiment of the present utility model, those having ordinary skill in the art will appreciate that: in the situation that not departing from principle of the present utility model and aim, can carry out multiple variation, amendment, replacement and modification to these embodiment, scope of the present utility model is limited by claim and equivalent thereof.
