Abstract
The utility model relates to a novel dropper for an infusion apparatus, comprising a dropper and a closing device, wherein one end of the dropper is provided with a hollow cylinder having a funnel; the closing device is arranged in the dropper; the closing device comprises thimbles, a buoyancy ball and a cone, wherein the thimbles, a buoyancy ball and a cone are connected successively from top to bottom; the shape of the cone is coordinated with the shape of the funnel of the dropper; a gravity ball is arranged in the cone; the dropper is arranged on the infusion apparatus; the thimbles are bar-type rods which are symmetrically arranged on the buoyancy ball; the buoyancy ball is a hollow plastic ball; and the gravity ball is made of metal. Compared with the prior arts, the novel dropper for an infusion apparatus has the advantages that: the novel dropper for an infusion apparatus has simple structure, reasonable design, convenient usage, flexibility and practicability; and the closing device is arranged in the dropper so as to effectively avoid the accident that the blood of a patient backflows or the air enters into blood vessels when the needle is not taken out or the infusion solution pipe is not closed in time when the infusion solution is finished.
Description
Technical field
This utility model relates to a kind of medical instruments, the particularly a kind of novel transfusion device dropper that can when transfusion finishes, close liquid-transport pipe-line automatically.
Background technology
In present medical instruments; Transfusion device is one of medical instruments general and the most commonly used, and transfusion set is made up of contact pin, dropper, gripping mechanism and syringe needle, and dropper is the hollow cylinder that the bottom is provided with funnel; Liquid level situation through observing in the dropper can be recognized transfusion process situation; When the liquid medicine in the infusion bottle is totally lost, when promptly not having liquid in liquid level decline or the dropper in the dropper, need the gripping mechanism chucking be pulled out syringe needle immediately and close liquid-transport pipe-line; Thereby prevent that blood is back to tube for transfusion or air admission blood vessel, causes the hemorrhage or bulge phenomenon of patient's pin hole.All do not find the situation that the liquid in the infusion bottle has been totally lost but patient and medical worker are taken place sometimes in medical procedure, cause patient blood to reflux or the air admission blood vessel, the serious malpractice that causes.
Therefore, the transfusion device in the medical instruments needs a kind of simple in structure, easy to use, can prevent effectively that patient blood from refluxing or the infusion set of air admission blood vessel.
Summary of the invention
The purpose of this utility model provides a kind of novel transfusion device dropper; Simple, reasonable in design, easy to use, the flexible practicality of this apparatus structure; Adopt shutoff device to be arranged in the dropper, the accident of patient blood backflow or air admission blood vessel takes place when effectively having prevented in time not take to pull out pin or close liquid-transport pipe-line after transfusion from finishing.
For realizing above-mentioned purpose, this utility model adopts following technical scheme to realize:
A kind of novel transfusion device dropper; Comprise dropper, shutoff device; Described dropper is the hollow cylinder that an end is provided with funnel, is provided with shutoff device in the dropper, and described shutoff device comprises thimble, buoyant spheres, the cone that connects successively from top to bottom; Cone shape matches with the dropper funnel shaped, and is provided with the gravity ball in the cone.
Described dropper is arranged on the transfusion device.
Described thimble is two bar shaped bars that are symmetricly set on the buoyant spheres.
Described buoyant spheres is hollow plastic sphere.
Described gravity ball adopts metal to process.
Compared with prior art; The beneficial effect of this utility model is: 1) the hollow buoyant spheres of this device employing is located in the liquid in the dropper and is floated on the liquid level in the dropper, makes shutoff device along with the liquid level in the dropper fluctuates, if transfusion finishes; Liquid level sinks; Buoyant spheres is also sunk thereupon, and shutoff device is close transfusion device in time, prevents that air admission blood vessel or blood from refluxing; 2) this device adopts thimble to be symmetricly set on the buoyant spheres top, has prevented that effectively shutoff device is arranged in the dropper, takes place if the too high buoyant spheres of liquid level can be stopped up the situation of dropper, and is safe and reliable; 3) this device shutoff device adopts the cone that matches with dropper below funnel to cut out dropper, and is simple in structure, practical; 4) this device adopts the gravity ball to be arranged in the cone, makes the shutoff device steadily of centre of gravity, and it is stable, reasonable in design to keep on the liquid level in dropper that direction is set.
Description of drawings
Fig. 1 is the structural representation of this utility model.
Fig. 2 is this utility model sketch map when finishing of in use infusing.
Fig. 3 is that this utility model thimble prevents to stop up the sketch map that liquid gets into dropper.
Among the figure: 1-dropper 2-thimble 3-buoyant spheres 4-cone 5-gravity ball 6-funnel 7-liquid level
The specific embodiment
Describe in further detail below in conjunction with the specific embodiment of accompanying drawing this utility model.
See Fig. 1, Fig. 2, Fig. 3, a kind of novel transfusion device dropper comprises dropper 1, shutoff device; Dropper 1 is the hollow cylinder that an end is provided with funnel 6, is provided with shutoff device in the dropper 1, and described shutoff device comprises thimble 2, buoyant spheres 3, the cone 4 that connects successively from top to bottom; Cone 4 shapes match with dropper 1 funnel 6 shapes; And be provided with gravity ball 5 in the cone 4, dropper 1 is arranged on the transfusion device, and thimble 2 is two bar shaped bars that are symmetricly set on the buoyant spheres 3; Buoyant spheres 3 is hollow plastic sphere, and gravity ball 5 adopts metal to process.
When this device used, when patient began to infuse, liquid got in the dropper 1, and buoyant spheres 3 floats on the liquid level 7; In dropper 1 liquid for a long time, thimble 2 withstands on dropper 1 upper wall, makes buoyant spheres 3 be unlikely to stop up dropper 1; Guarantee to infuse and carry out smoothly, when transfusion finished, liquid reduced in the dropper 1; Liquid level 7 descends, and buoyant spheres 3 is followed liquid level 7 and descended, and the cone 4 that is arranged on buoyant spheres 3 belows gets lodged in funnel 6 places of dropper 1; Closed transfusion device, under the effect that does not need manpower, prevented that effectively patient blood from refluxing or the situation of air admission blood vessel takes place.
