Abstract
The utility model discloses a take contrary transfusion system of ending of locating part to drip kettle is provided with top inlet and bottom liquid outlet on the kettle, set up buoyant member in the kettle, and buoyant member's bottom surface opening is provided with rubber membrane, and buoyant member and rubber membrane form the cavity floating body, are provided with the direction locating part in the kettle, and the locating part that leads encloses the lift passageway that the synthesis is used for holding buoyant member. This take contrary transfusion system of ending of locating part to drip kettle simple structure, convenient to use, through using the locating part that leads its inside setting, the direction locating part encloses the synthetic lift passageway that holds buoyant member, and the cross section of the passageway that should go up and down is lighter than the cross section that drips the kettle, so the former use amount of foreseeing the disposable consumptive materials such as rubber membrane of bottom of reduction that can be corresponding manufacturing buoyant member's barrel.
Description
Technical field
This utility model relates to medical product field, is specifically related to a kind of non-return transfusion device with locating part and drips kettle.
Background technology
Venous transfusion utilizes atmospheric pressure and fluid pressure principle by electrolyte, medicine by the method in vein input body.Conventional intravenous is connected with droplet kettle of an internal diameter much larger than tube for transfusion, and its effect is convenient speed of observing drop, to avoid the phenomenon occurring venous return when liquid drug exhausts in appearance point drop bottle.In daily life, normal appearance causes transfusion liquid to be finished the malpractice of blood backflow due to personnel's carelessness.In order to avoid the generation of above-mentioned situation, preferred technical scheme adopts and arranges dripping in kettle of tube for transfusion the buoyant member that bottom surface is rubber membrane, when dripping kettle herb liquid liquid level and being higher, buoyant member is floating state, when dripping kettle herb liquid liquid level and declining because infusion bottle medicinal liquid exhausts, the pressure of rubber membrane both sides not etc., by utilizing the deadweight of liquid level lower than buoyant member during minim pipette bottom and the pressure differential of thin film both sides, on the liquid outlet that rubber film is sealed in bottom minim pipette.Tube for transfusion is disposable medical consumptive material, gap is there is in buoyant member with the inner surface dripping kettle, therefore need to increase position-arresting disk in buoyant member, transverse shakiness in kettle is being dripped to avoid buoyant member, and the deadweight of buoyant member also needs to control, otherwise affect non-return effect, the complex structure of buoyant member in said structure.Therefore, be necessary that dripping kettle to non-return transfusion device carries out structure improvement.
Utility model content
The purpose of this utility model is to overcome the defect existed in prior art, provides the non-return transfusion device of simple, the non-return effective band locating part of a kind of structure to drip kettle.
For realizing above-mentioned technique effect, the technical solution of the utility model is: a kind of non-return transfusion device with locating part drips kettle, it is characterized in that, described kettle is that integral type flexibility drips kettle, described kettle is provided with top inlet and bottom liquid outlet, in described kettle, buoyant member is set, the bottom surface opening of described buoyant member is provided with rubber film, described buoyant member and rubber film form hollow floating body, be provided with guide and limit part in described kettle, described guide and limit part encloses the liftway for holding buoyant member.
Preferred technical scheme is, described guide and limit part is several banking stops, and the side of banking stop described in several is connected with the inner surface dripping kettle, and the another side of several banking stops described encloses the passage holding buoyant member lifting.
Preferred technical scheme is, described guide and limit part is some spacing lines, one end of some described spacing lines is fixedly connected with the end face dripping kettle, and the other end of described spacing line is fixedly connected with the bottom surface of dripping kettle, and described some spacing lines enclose the passage holding buoyant member lifting.
Preferred technical scheme is, described banking stop or spacing line are uniformly distributed along the inner surface axial of described kettle.
Preferred technical scheme is, described guide and limit part is flexible limit part.
Advantage of the present utility model and beneficial effect are:
It is simple that the non-return transfusion device of this band locating part drips kettle structure, easy to use, by arranging guide and limit part therein, guide and limit part encloses the liftway holding buoyant member, the cross section of this liftway is less than the cross section dripping kettle, the use amount of medical disposable material such as minimizing manufacture the cylindrical shell raw material of buoyant member and the rubber film of bottom etc. that therefore can be corresponding.

Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
Embodiment 1
As depicted in figs. 1 and 2, the non-return transfusion device of embodiment 1 with locating part drips kettle, drip on kettle 1 and be provided with top inlet 2 and bottom liquid outlet 3, drip in kettle 1 and buoyant member 4 is set, the bottom surface opening of buoyant member 4 is provided with rubber film 5, buoyant member 4 and rubber film 5 form hollow floating body, and drip in kettle and be provided with guide and limit part, guide and limit part encloses the liftway for holding buoyant member 4.
Dripping kettle 1 is that integral type flexibility drips kettle, and guide and limit part is flexible limit part.
Guide and limit part is several banking stops 6, and the side of several banking stops 6 is connected with the inner surface dripping kettle, and the another side of several banking stops 6 encloses the passage holding buoyant member lifting; Banking stop 6 drips kettle 1 inner surface axial along flexibility and is uniformly distributed.
Embodiment 2
As shown in Figure 3 and Figure 4, embodiment 2 is from the different of embodiment 1, guide and limit part in embodiment 2 is some spacing lines 7, one end of some spacing lines 7 is fixedly connected with the end face dripping kettle 1, the other end of spacing line 7 is fixedly connected with the bottom surface of dripping kettle 1, and some spacing lines 7 enclose the passage holding buoyant member 4 and be elevated.
Spacing line 7 is uniformly distributed along the inner surface axial dripping kettle.
The number of banking stop and spacing line is at least three, the cross section of spacing line be circle, triangle, rectangle, ellipse etc. any one, be preferably linear contact lay between buoyant member and locating part.
Being that integral type flexibility drips kettle owing to dripping a kettle, is therefore just need hollow floating body to be arranged on to drip in kettle in manufacture.Flexible spacing line consumptive material used is minimum.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from this utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
