Abstract
The utility model relates to a self-stop Murphy burette, which comprises an upper interface, a burette body, a floating ball and a lower interface. The upper end of the burette body is provided with the upper interface which is used to connect with a drainage tube at the upper section. The lower end of the burette body is provided with the lower interface which is used to connect with a drainage tube at the lower section. The floating ball is arranged in the burette body. Corresponding to the floating ball, the upper end of the lower interface in the burette body is arranged to be a shape of a round funnel, so the floating ball is convenient to reliably close down the lower interface when the floating ball gets down to the lowest end. When being filled with liquid, the floating ball floats on the surface of the liquid. When the vein injection is approximately finished, the surface of the liquid in the burette body gradually gets down, and the floating ball also gets down following the liquid surface. So the goal of automatic stop is realized. The utility model has the advantages of simple structure and easy use. The automatic stop after transfusion can be realized. The phenomenon of blood return after finishing the transfusion can be avoided.
Description
Technical field:
This utility model relates to medical apparatus, relates in particular to the automatic stop type Murphy's dropper.
Background technology:
The Murphy's dropper device that in making the intravenous drip process, is absolutely necessary, owing in the intravenous drip process, do not have and self-brakingly to install, so after the liquid in liquid bottles all instils and is over, liquid can continue descending, until the blood back phenomenon takes place under the not enough situation of pressure, instil also for follow-up continuation and caused very big trouble.
The utility model content:
The purpose of this utility model is, overcomes the deficiencies in the prior art part, and a kind of automatic stop type Murphy's dropper is provided, and when can the liquid in dropper being reduced to end opening the end opening of dropper is sealed automatically, reaches self-braking purpose.
Automatic stop type Murphy's dropper described in the utility model includes interface, dropper body, ball float and lower interface and forms, and said dropper body is the main component of automatic stop type Murphy's dropper described in the utility model.The upper end of dropper body is set to interface, is used for being connected with the drainage tube of epimere; The lower end of dropper body is set to lower interface, is used for being connected with the drainage tube of hypomere.Be provided with ball float in the dropper body, corresponding with ball float, be set to the shape of circle funnel in the upper end dropper body of lower interface, so that ball float can seal lower interface when going downwards to bottom steadily.When in the dropper body liquid being arranged, ball float can float over automatically liquid above, as marquis when finishing intravenous drip, liquid in the Murphy's dropper does not have under the new situation of replenishing, and the intravital liquid of dropper is downward gradually, and ball float also can be downward thereupon, until the lowermost end that arrives the dropper body, the sealing lower interface, it is descending to make that liquid in the drainage tube below the lower interface can not continue, and has also just reached self-braking purpose.
Automatic stop type Murphy's dropper described in the utility model, overall structure is simple, and is easy to use, can realize stopping automatically after finishing transfusion instils, and the blood back phenomenon of avoiding infusing after finishing takes place.
Description of drawings:
Accompanying drawing is the structural representation of automatic stop type Murphy's dropper described in the utility model.The last interface 2-of 1-dropper body 3-ball float 4-lower interface
The specific embodiment:
Referring now to accompanying drawing, be described as follows in conjunction with the embodiments: automatic stop type Murphy's dropper described in the utility model, include interface 1, dropper body 2, ball float 3 and lower interface 4 and form, said dropper body 2 is main components of automatic stop type Murphy's dropper described in the utility model.The upper end of dropper body 2 is set to interface 1, is used for being connected with the drainage tube of epimere; The lower end of dropper body 2 is set to lower interface 4, is used for being connected with the drainage tube of hypomere.Be provided with ball float 3 in the dropper body 2, corresponding with ball float 3, be set to the shape of circle funnel in the upper end dropper body 2 of lower interface 4, so that ball float 3 can seal lower interface 4 when going downwards to bottom steadily.When in the dropper body 2 liquid being arranged, ball float 3 can float over automatically liquid above, as marquis when finishing intravenous drip, liquid in the Murphy's dropper is not having under the new situation of replenishing, and the liquid side in the dropper body 2 is downward gradually, and ball float 3 also can be downward thereupon, until the lowermost end that arrives dropper body 2, sealing lower interface 4, it is descending to make that the lower interface 4 following interior liquid of drainage tube can not continue, and has also just reached self-braking purpose.Automatic stop type Murphy's dropper described in the utility model, overall structure is simple, and is easy to use, can realize stopping automatically after finishing transfusion instils, and the blood back phenomenon of avoiding infusing after finishing takes place.
