Abstract
The utility model relates to a Murphy dripping tube with a spherical float valve. The Murphy dripping tube comprises a tube body. The spherical float valve capable of floating on the liquid level of the tube body is arranged in the tube body. As the spherical float valve is arranged in the tube body, after infusion is finished, by means of attaching of the spherical float valve and the bottom of the tube body, air can not enter a liquid outlet tube, the purpose of preventing blood return is achieved, exhaust operation is avoided, the working pressure is lowered, and the Murphy dripping tube has the advantages of being simple in structure, safe and convenient to use and capable of preventing blood return.
Description
Technical field
This utility model belongs to the Murphy's burette technical field, relates to a kind of Murphy's burette with the ball-type float valve.
Background technology
Existing Murphy's burette comprises the body that is provided with inlet and liquid outlet, liquid enters in body from inlet, directly from liquid outlet, drip again, in the intravenous drip process, in bottle, liquid is exported when complete, air can enter in infusion pipeline, if at this moment patient, medical personnel do not find in time or process, adverse consequences will occur: the one, if injection inlet is at vein negative pressure section, the air that enters so infusion pipeline will be inhaled in vein blood vessel, and this result can work the mischief to human body, the 2nd, if injection inlet is positioned at vein malleation section, when the decline of liquid medicine liquid level reaches the pressure balance of intravenous injection porch, in tube for transfusion, liquid do not injecting human body, under this situation, because the factors such as the diffusion between liquid medicine and blood or position of human body change cause the fluctuation of blood pressure, capital enters in injection needle the blood backflow in blood vessel, if at this moment process not in time, blood in the intravasation thromboembolism injection needle that will condense, this result causes continuing supplementing or the injection of changing dressings, renew transfusion and must again change needle tubing and position inserting needle, this brings more misery also to medical personnel, to bring more work and waste to patient, the patient this repetition inserting needle tiny for some blood vessels is very difficult, and meet anxious heavy patient, more can delay treatment opportunity.In addition, air enters in the pipeline under the Murphy's burette delivery outlet, even in time dosing, the transfusion of changing dressings also needs to carry out bleeding, increase nursing staff work load.
The utility model content
In order to overcome the above-mentioned shortcoming of prior art
,this utility model provides a kind of and has simple in structurely, easy to use, has avoided the Murphy's burette with the ball-type float valve of blood back problem characteristics.
This utility model solves the technical scheme that its technical problem adopts: a kind of Murphy's burette with the ball-type float valve, comprise body, and be provided with a ball-type float valve that can float at the body liquid level in body.
Be respectively equipped with feed tube and a drain pipe connected with body at the two ends up and down of described body.
The bottom shape of described body is fit with the ball-type float valve and make the ball-type float valve can intercept the arc body of drain pipe and body circulation.
Be provided with gap between described ball-type float valve and the body left and right sides.
The beneficial effects of the utility model are: by the ball-type float valve is set in body, can be by the laminating of ball-type float valve and body bottom after infusion-completed, guarantee that drain pipe can not enter air, with reach not can blood back purpose, thereby avoided bleeding, reduced operating pressure, had simple in structure, safe and convenient to use and avoided the characteristics of blood back.
The accompanying drawing explanation
Fig. 1 is this utility model structural representation.
In figure: 1-body, 2-feed tube, 3-drain pipe, 4-ball-type float valve, 5-bottom.
The specific embodiment
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Referring to Fig. 1, a kind of Murphy's burette with the ball-type float valve, comprise body 1, be respectively equipped with feed tube 2 and a drain pipe 3 connected with body 1 at the two ends up and down of body 1, be provided with a ball-type float valve 4 that can float at body 1 liquid level in body 1, be provided with gap between ball-type float valve 4 and body 1 left and right sides, bottom 5 shapes of body 1 are fit with ball-type float valve 4 and make ball-type float valve 4 can intercept the arc body of drain pipe 3 and body 1 circulation.
This utility model by arranging the ball-type float valve in body, can be by the laminating of ball-type float valve and body bottom after infusion-completed, guarantee that drain pipe can not enter air, with reach not can blood back purpose, thereby avoided bleeding, reduced operating pressure, had simple in structure, safe and convenient to use and avoided the characteristics of blood back.
