Abstract
An easily-exhaust infusion apparatus relates to an infusion apparatus for intravenous drip and comprises the same structure as the prior art, including a puncture needle, a solution delivery pipe, a Murphy's dropper, an adjustment switch, an infusion needle, and a connector. The infusion apparatus is characterized in that a dilatation expansion tube is provided between the Murphy's dropper and the adjustment switch, to rapidly and safely remove the air from the solution delivery pipe when changing the dropping bottle. The utility model has the advantages of simple structure, easy operation and low cost.
Description
Technical field
This utility model belongs to medical infusion apparatus technical field, particularly relates to the intravenous drip transfusion device.
Background technology
At present, clinical intravenous drip transfusion device commonly used is the disposable pipe transfusion device of moulding that is made of needle for inserting bottle, catheter, Murphy type burette, by-pass cock, intravenous needle and joint etc.It in use, after one bottle of liquid is totally lost, liquid level is often reduced to below the Murphy type burette, after changing new solution bottle, re-fill liquid in the Murphy type burette immediately, but tend to produce one section the air gap this moment in a joint catheter of Murphy type burette bottom, could continue transfusion after must getting rid of, conventional method for removing is to squeeze, play catheter and Murphy type burette, make inner air tube enter the air cavity on Murphy type burette top, or tube for transfusion pulled up from the joint carry out the discharge opeing aerofluxus, operation is wasted time and energy, and discharge opeing also pollutes the environment.
Summary of the invention
The purpose of this utility model is that existing intravenous drip transfusion device is carried out technological improvement, thereby makes bleeding quick and convenient, and need not to dismantle catheter.
The technical solution of the utility model is: it comprises needle for inserting bottle, catheter, Murphy type burette, by-pass cock, intravenous needle and joint, it is characterized in that having additional between Murphy type burette and by-pass cock the dilatation expansion tube.
The beneficial effects of the utility model are: when changing infusion bottle, by the more liquid of storing in the extruding dilatation expansion tube, can finish bleeding fast easily easily with entering the air cavity portion that a small amount of gas in the drain pipeline section drains into Murphy type burette between Murphy type burette and the dilatation expansion tube.This utility model is simple in structure, and overall appearance is consistent with existing intravenous drip transfusion device with using method, and manufacturing process is identical with existing transfusion device, and cost increases slight.
Description of drawings
Accompanying drawing is a population structure sketch map of the present utility model.
The specific embodiment
Constitute most of assembly of the present utility model, as needle for inserting bottle 1, catheter 2, Murphy type burette 3, by-pass cock 5, joint 6 and intravenous needle 7, basically identical with existing disposable vein drip transfusion device, its make material and production technology also basic identical, just this utility model has been set up the dilatation expansion tube 4 similar to Murphy type burette between Murphy type burette 3 and by-pass cock 5.This dilatation expansion tube 4 be preferably disposed on joint 6 on 30-40 centimetre catheter, after guaranteeing that liquid is totally lost, the unlikely dilatation expansion tube of reducing to of liquid level is below 4.
Claims (2)
1, a kind of easy exhaust transfusion device, comprise needle for inserting bottle (1), catheter (2), Murphy type burette (3), by-pass cock (5), joint (6) and intravenous needle (7), it is characterized in that between Murphy type burette (3) and by-pass cock (5), having additional dilatation expansion tube (4).
2, by the described easy exhaust transfusion device of claim 1, it is characterized in that dilatation expansion tube (4) be arranged on joint (6) on 30-40 centimetre catheter (2).
