Abstract
The utility model belongs to a medical device, particularly an improved transfusion device which comprises a puncture device, a dropping kettle and a needle head connector which are orderly connected together in series by a transfusion hose, a needle head which is together inserted and connected with a needle head connector by a capillary transfusion tube hose, and a flow regulator which is movably arranged on a transfusion hose between the dropping kettle and the needle head connector, wherein, an exhaust device is connected with one place, which approaches to one end of the needle head connector, on the transfusion hose arranged between the dropping kettle and the needle head connector. The flow regulator is limited on the transfusion hose between the exhaust device and the needle head connector. The utility model has the characteristics of convenient and simple use and easy operation.
Description
This utility model relates to a kind of improvement of medical supplies, is meant a kind of improved transfusion device especially.
At present, generally the medical Transfusion device of Shi Yonging is when being used to infuse, if run into when once needing to import many bottle liquid medicines, generally all be to change bottle not change transfusion device, in order to be unlikely to when changing dressings bottle, have in the air admission transfusion device, just need medical personnel when last bottle liquid medicine is about to use up, in time change medicine bottle; But in actual mechanical process, the phenomenon of new medicine bottle often appears just changing after last bottle liquid medicine is fully used up for various reasons, entered air in the transfusion device pipeline this moment, after finishing changing new medicine bottle, need medical personnel infusion tube to be unpluged by the syringe needle connector, solve connecting again after the discharge of the air in the transfusion device pipeline, has operating performance craftsmenship requirement height loaded down with trivial details, that easily cause medicine to waste and pollute, be difficult for thoroughly draining air and operate, not wield problem.
The purpose of this utility model is to addressing the above problem, and a kind of simple to operate, easy is provided, and can thoroughly the air in the transfusion device pipeline be discharged, and can not cause a kind of improved transfusion device of liquid medicine contamination and waste.
The purpose of this utility model is achieved in that a kind of improved transfusion device, comprise the perforator that is serially connected successively by infusion tube, the syringe needle that drips kettle, syringe needle connector and be plugged on the syringe needle connector, and be movably arranged on the flow regulator on the infusion tube that drips between kettle and the syringe needle connector by capillary tube for transfusion flexible pipe; Wherein on the infusion tube that drips between kettle and the syringe needle connector, also be connected in series an exhaust apparatus near an end of syringe needle connector, and flow regulator is limited on the infusion tube between this exhaust apparatus and the syringe needle connector.
Exhaust apparatus is by a three way cock and be movably arranged on the end cap that the three way cock goes up the emptying channel end and form.
Because this utility model has been set up an emptying passage on the pipeline of the bottom of transfusion device, and the position of this emptying passage is lower than transfusion device liquid can drop in the infusion tube when correctly using minimum liquid level line, so after entering gas in the transfusion device pipeline, only need with flow regulator infusion tube to be closed earlier, open the end cap that the three way cock goes up the emptying channel end then, gas in the transfusion device pipeline can be discharged from the emptying passage under the pressure of bottle herb liquid of newly changing dressings smoothly, when medicinal liquid begins to flow out from the emptying passage, can cover end cap, bleeding finishes; Have characteristics easy to use, simple, wield.
Below in conjunction with drawings and Examples this utility model is further described:
Fig. 1 is existing transfusion device
Fig. 2 is a transfusion device described in the utility model
Fig. 3 is an another kind of modified model of the present utility model
A kind of improved transfusion device, comprise the perforator 7 that is serially connected successively by infusion tube 5, the syringe needle 1 that drips kettle 6, syringe needle connector 3 and be plugged on syringe needle connector 3, and be movably arranged on the flow regulator 4 on the infusion tube 5 that drips between kettle 6 and the syringe needle connector 3 by capillary tube for transfusion flexible pipe 2; Wherein on the infusion tube 5 that drips between kettle 6 and the syringe needle connector 3, also be connected in series an exhaust apparatus near an end of syringe needle connector 3, and flow regulator 4 is limited on the infusion tube 5 between this exhaust apparatus and the syringe needle connector 3.Exhaust apparatus is made up of a three way cock 8 and the end cap 10 that is movably arranged on emptying passage 9 ends on the three way cock 8, and this three way cock 8 is serially connected on the infusion tube 5 by its two other passage.
Because the cause of blood in human body in hydraulic coupling, in infusion process, after the whole emptyings of the liquid in the medicine bottle, the medicinal liquid in the transfusion device pipeline can't all be input in the blood vessel, and it has a certain amount of accumulating in the pipeline of transfusion device bottom; The position of exhaust apparatus must be arranged on the infusion tube 5 that is lower than below the liquid level line that accumulates medicinal liquid on transfusion device this moment in the infusion tube 5 on this utility model; When changing medicine bottle, at first close infusion tube 5 with flow regulator, again new medicine bottle is finished changing, open the end cap 10 of emptying passage 9 ends on the three way cock 8 then, gas in the transfusion device pipeline can be discharged from emptying passage 9 under the pressure of bottle herb liquid of newly changing dressings smoothly, when medicinal liquid begins to flow out from emptying passage 9, can cover end cap 10, bleeding finishes.
In addition, if between emptying passage 9 on the three way cock 8 and end cap 10, be connected in series one section infusion tube 11, then in exhaust process, when medicinal liquid enters this section infusion tube 11, just end cap 10 can be covered, do not leak thereby can accomplish to drip medicine, and can not contact medicinal liquid, can not cause the pollution of medicinal liquid.
