Description

Liquid is joined defeated device

Technical field

This utility model belongs to medical instruments field, relates to the improvement to the transfusion apparatus.

Background technology

Referring to Fig. 1, existing transfusion device is disposable plastic, it by fluid-directing needle 1, Murphy type tube 8, controller 10, transfusion needle joint 11, transfusion needle 14, inducing QI pin 5, air filter 7, connect inducing QI pin 5 and air filter 7 airway 6, is connected the catheter 9 of fluid-directing needle 1 and Murphy type tube 8 and is connected Murphy type tube 8 and the catheter 9 of transfusion needle joint 11 is formed, controller 10 is enclosed within on the catheter 9 of connection Murphy type tube 8 and transfusion needle joint 11.This transfusion device only can be used for transfusion, can not be used for dosing.When the needs dosing, generally use the syringe of various calibers from cell therefor, to extract liquid, be expelled in the infusion vessel again and go.This dosing method wastes time and energy, and will consume syringe, increases the cost of transfusion.

Summary of the invention

The purpose of this utility model is: provide a kind of and can be used to infuse, can be used for again defeated device of joining of dosing, to make things convenient for the dosing operation, reduce the transfusion cost.

The technical solution of the utility model is: a kind of liquid is joined defeated device, by fluid-directing needle 1, Murphy type tube 8, controller 10, transfusion needle joint 11, transfusion needle 14, inducing QI pin 5, air filter 7, the airway 6 that connects inducing QI pin 5 and air filter 7, connect the catheter 9 of fluid-directing needle 1 and Murphy type tube 8 and be connected Murphy type tube 8 and the catheter of transfusion needle joint 11 9 compositions, controller 10 is enclosed within on the catheter 9 that connects Murphy type tube 8 and transfusion needle joint 11, it is characterized in that, but the

gripping object

3 and 4 that has two relative tubular axis lines to be symmetrically distributed at the outer wall middle part of Murphy type tube 8, but should firmly be connected with the outer wall of Murphy type tube 8 by gripping object.

The utility model has the advantages that: it not only has the transfusion function, and can carry out the dosing operation, can save syringe, reduces the transfusion cost.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 (a) to (f) but be 6 kinds of different structural representations of said gripping object.

The specific embodiment

Below this utility model is described in further details.This utility model is by fluid-directing needle 1, Murphy type tube 8, controller 10, transfusion needle joint 11, transfusion needle 14, inducing QI pin 5, air filter 7, the airway 6 that connects inducing QI pin 5 and air filter 7, connect the catheter 9 of fluid-directing needle 1 and Murphy type tube 8 and be connected Murphy type tube 8 and the catheter of transfusion needle joint 11 9 compositions, controller 10 is enclosed within on the catheter 9 that connects Murphy type tube 8 and transfusion needle joint 11, it is characterized in that, but the

gripping object

But above said gripping

object

3 and 4 structure be one of following structure:

(1) be the spike structure, the head of a nail is followed closely the sense bar and is connected with the outer wall of Murphy type tube 8 outside;

(2) be circulus, the ring outer rim is connected with the outer wall of Murphy type tube 8;

(3) be cylinder, its outer rim is connected with the outer wall of Murphy type tube 8;

(4) be triangular prism, an one side is connected with the outer wall of Murphy type tube 8;

(5) be hexahedron, an one side is connected with the outer wall of Murphy type tube 8;

(6) be catch shape, two column is connected with the outer wall of Murphy type tube 8;

(7) be bathtub construction, notch is outside, and bottom land is connected with the outer wall of Murphy type tube 8;

(8) be the auricle structure, its base is connected with the outer wall of Murphy type tube 8.

It is identical that this utility model carries out the principle and the existing transfusion device of transfusion operation.The process that it carries out the dosing operation is: suppose and will join transfusion to the second container from the first container, fluid-directing needle 1 and inducing QI pin 5 are inserted the first container, select the suitable dosing pin 13 of caliber to be connected with transfusion needle joint 11; Clamp the catheter 9 that connects Murphy type tube 8 and transfusion needle joint 11 then, make its sealing; But clamping

gripping object

3 and 4 compresses and draws back Murphy type tube 8, makes liquid flow into Murphy type tube 8 from the first container; Unclamp the catheter 9 that connects Murphy type tube 8 and transfusion needle joint 11 then, clamp the catheter 9 that connects fluid-directing needle 1 and Murphy type tube 8, compression Murphy type tube 8, liquid just flows into the second container.Vice versa.By the wheel of the control on the adjustment control 10 12, can regulate the dosing flow.

Because the Murphy type tube 8 of existing transfusion device be a cylinder, compress and draw back not thoroughly, so the profile of said Murphy type tube 8 is preferably flying saucer shape or spindle, so that compress and draw back operation.

For the ease of inserting dosing pin 13 to the purpose container, can connect as one said controller 10 with transfusion needle joint 11, be convenient to like this control.

Prevent during for dosing that liquid from retaining in Murphy type tube 8, can open side opening, generally open a side opening and get final product at the dropper root in the Murphy type tube 8.
