Abstract
The utility model provides an automatically closed disposable infusion device which mainly comprises a needle for inserting a bottle, a liquid dropping bucket, a joint of an infusion needle, and a catheter used for communicating the liquid dropping bucket with the joint of the infusion needle, wherein a sealing ring with a central hole and a float corresponding to the central hole of the sealing ring are arranged on the lower part of the inside of the liquid dropping bucket. When infusion liquor is used out, the float automatically seal the hole on the lower end of the liquid dropping bucket to prevent air entering blood vessels of a human body and to avoid generating unexpected accidents.
Description
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of medical automatic closed disposable transfusion device.
At present, infuse the disposable transfusion device that mainly uses drip bottle and needle for inserting bottle, dropping liquid bucket, conduit, adjustment dop and transfusion needle to constitute to patient.The drip bottle only plays the splendid attire medicinal liquid, and the dropping liquid bucket only works to monitor liquid droping speed.When the transfusion in the drip bottle is about to be totally lost, can not seal automatically, make a bottle interior air admission human vas easily, cause contingency with this.Therefore the patient of transfusion must someone nurse at one's side, so not only influences patient and has a rest, and also influences the good environment in ward.
The purpose of this utility model is a kind of disposable transfusion device that can seal automatically when transfusion finishes that designs at above-mentioned shortcoming.
The purpose of this utility model is achieved in that it comprises the conduit of needle for inserting bottle, dropping liquid bucket, transfusion needle joint and connection dropping liquid bucket and transfusion needle joint and is located at supravasal adjustment dop, its technical characterictic is: needle for inserting bottle and dropping liquid bucket directly are connected, and the bottom is provided with the sealing ring and a float corresponding with this sealing ring centre bore of band centre bore in the dropping liquid bucket.When liquid is flowed in the dropping liquid bucket by Liquid dropping bottle, to a certain degree the time,, open fluid path because the buoyancy of liquid effect makes float leave the centre bore of sealing, make in the liquid inflow catheter.When no liquid in the Liquid dropping bottle splashed into the dropping liquid bucket, float just relied on deadweight to fall in the centre bore of sealing ring, the choke-out of dropping liquid bucket hypomere, air can not be flow in the conduit.
Do not choose when distinguishing feature of the present utility model is patient infusion and guard, when dropping liquid finishes, can seal automatically, prevent the air admission human vas, avoid the generation of contingency.
Detail of the present utility model is provided by following examples and accompanying drawing thereof:
With reference to accompanying drawing, this utility model comprises needle for inserting bottle 3, dropping liquid bucket, conduit, adjustment dop 10 and transfusion needle joint 13, is connected with air inlet pipe 1 on the needle for inserting bottle 3, and the dropping liquid bucket constitutes by upper and lower two section 4,6.Conduit is made of plastic catheter 9, connection plug 11 and latex catheter 12.Dropping liquid bucket epimere 4 directly is connected with needle for inserting bottle 3.Dropping liquid bucket hypomere 6 is communicated with transfusion needle joint 13 by conduit, the bottom is provided with the enclosed elastic circle 8 and a float 7 corresponding with this sealing ring centre bore of a band centre bore in the dropping liquid bucket, float 7 tops are provided with the stop tab of a band centre bore, and it is floating too high to prevent that float from making progress.Needle for inserting bottle 3 and transfusion needle joint 13 ports are respectively equipped with protective cover 2 and 14.Below the component materials of specified otherwise does not adopt working of plastics to make.
Claims (2)
1, a kind of automatic closed disposable transfusion device, it comprises needle for inserting bottle, dropping liquid bucket, transfusion needle joint and is communicated with the conduit of dropping liquid bucket and transfusion needle joint and is located at supravasal adjustment dop, it is characterized in that: needle for inserting bottle and dropping liquid bucket directly are connected, and the bottom is provided with the sealing ring and a float corresponding with this sealing ring centre bore of band centre bore in the dropping liquid bucket.
2, automatic closed disposable transfusion device according to claim 1 is characterized in that: in the dropping liquid bucket float above be provided with one and prevent the float floating excessive stop tab that has centre bore that makes progress.
