Abstract
Transfusion device provided by the invention, adopted by a metal guide pin of extracting again after thrusting and one with staying of making of the high molecular polymer compound syringe needle that endovascular soft pin constitutes, be fixed on the three-way valve that two input channels are arranged of wrist or ankle and can connect the cross valve of one of three liquid bottles respectively with fixing band, therefore, it can simultaneously or import several different medicinal liquids in succession, but and suspend transfusion by closing three-way valve behind the one-time puncture, in order to continuing transfusion (in three days) next time, or make things convenient for patient activity (as go to toilet etc.).The remaining parts of this transfusion device except that the metal guide pin made by high molecular polymer, and be with low cost, can be used as disposable transfusion device and use.
Description
The invention belongs to from vein blood vessel the intravital transfusion apparatus of medical medium input people.
With the immediate medical Transfusion device of the present invention, by thrust intravenous by a metal guide pin of extracting again after thrusting with one with staying of making of the high molecular polymer compound syringe needle that endovascular soft pin constitutes, flow rate regulating valve, observation drip velocity with emergently add medicinal pipkin, and formed with the flexible pipe that inserting mode is connected above each several part.There is following deficiency in this transfusion device: puncture each time (1) can only import a kind of liquid; When needs during from the quick administration of vein, can only add medicinal liquid from pipkin, slowly flow in the blood vessel with institute's loading liquid, required time is long, often can not satisfy the requirement of clinical " administration fast ".And because pipkin mouth and syringe conehead are misfitted, nurse operation gets up difficult, and medicinal liquid is expelled to outside the pipe.(2) can active patient often owing to transfusion has been limited necessary activity (as go to toilet etc.).(3) patient who regularly infuses every day, the hardship that all will be subjected to every day syringe needle to thrust blood vessel.(4) pipeline everywhere be connected to plug-in type, be easy to throw off or leak, even be directed at hemorrhage and gas embolism.
Purpose of the present invention, be to provide a kind of medical Transfusion device that can overcome above-mentioned transfusion device weak point, can import two or more liquid simultaneously, can temporarily disconnected when needing the transfusion path connect and the pipe interface transfusion device that can not throw off or leak everywhere when making things convenient for patient activity or treating the next time transfusion again.
A kind of transfusion device that can reach the foregoing invention purpose provided by the present invention, bag expand thrust use in the vein blood vessel stay the compound syringe needle that endovascular soft pin constitutes by a metal guide pin of extracting again after thrusting and one with what high molecular polymer was made, flow rate regulating valve, observe the pipkin that drip velocity is used, with the high molecular polymer flexible pipe that is connected above each several part, on the soft pin of its compound syringe needle except that the input channel of inserting the metal guide pin, also has another input channel, the interface section of two passages all is that internal orifice is the taper hole of standard syringe tapering, there is externally threaded interface tube the outside, can screw on and be with the injection tapered end or the seal cover of the outer conehead identical with the aperture tapering, also can have outer cone and the clamp nut that matches with the aperture by an end, the joint that the other end has the anti-awl that matches with flexible pipe connects tube for transfusion, and there are small pieces that scribble medical pressure-sensitive adhesive in said soft crown portion, is used for soft pin is attached on patient's the skin.
In order further to increase infusion channel, the flow rate regulating valve of above-mentioned transfusion device can be made both scalable flow velocity, also can connect or close the three-way valve of one or two infusion channel on it, and be furnished with this valve is fixed on patient's wrist, the fixing band at ankle or other positions of health, two input interfaces of this valve all are that inner orifice is the taper hole of standard syringe tapering, there is externally threaded interface tube the outside, both can connect infusion tube by joint described in the aforementioned transfusion device, also can screw on one with aforementioned transfusion device in identical seal cover, output interface has outer cone and rotatable nut of standard taper.
In order further to increase infusion channel, to meet the needs of the patient's who imports multiple medicinal liquid situation, can on the pipkin of aforementioned first kind of transfusion device or second kind of transfusion device and the runner between the infusion bottle, connect a cross valve with three input interfaces and an output interface, its each input interface is that inner orifice is the taper hole of standard syringe tapering, there is externally threaded interface tube the outside, output interface has standard outer cone and a rotatable nut, all can connect infusion tube by the joint described in the aforementioned transfusion device, also can screw on one with aforementioned transfusion device in identical seal cover, the spool that rotates this cross valve can make its output interface connect in three input interfaces any one, and three input interfaces are connected three different infusion bottles respectively.
Above-mentioned transfusion device provided by the present invention has following advantage:
(1) adopt transfusion device provided by the present invention, puncture once can be finished multichannel simultaneously or the work of transfusion in succession, because compound syringe needle, three-way valve, cross valve all provide the condition that increases the transfusion path.The stand-by channel of compound syringe needle also can be used as in venous transfusion the path that carries out " administration fast ".
(2) some patient infuses every day, but do not need twenty four hours to keep, in this case, can close three-way valve and cross valve, disconnect the liquid road that is connected with three-way valve, corresponding joint at three-way valve injects a small amount of heparin saline, and cover the external spiral interface with seal cover, when waiting to need transfusion, open seal cover, connecting corresponding tube for transfusion can infuse, and has removed the misery of puncture once more from.This compound syringe needle can keep in blood vessel three days.Same method can be used for can be active patient's upside institute etc.
(3) adopt the small pieces that scribble medical pressure-sensitive adhesive that syringe needle is fixed on the patient skin, convenient and firm.
(4) remaining parts of transfusion device of the present invention except that the metal guide pin all adopts high molecular polymer to make, and technical process is simple, and is with low cost, can be used as disposable transfusion device.
For several different preferred embodiment of transfusion device provided by the invention is described better, schematically they are expressed with following accompanying drawing:
Accompanying drawing 1-is by compound syringe needle, flow rate regulating valve, pipkin, infusion bottle and connect a kind of transfusion device that flexible pipe is formed;
Accompanying drawing 2-is by compound syringe needle, three-way valve and fixing band thereof, pipkin, infusion bottle and connect a kind of transfusion device that flexible pipe is formed;
Accompanying drawing 3-is by compound syringe needle, flow rate regulating valve, pipkin, cross valve, infusion bottle and connect a kind of transfusion device that flexible pipe is formed;
Accompanying drawing 4-is by compound syringe needle, three-way valve and fixing band thereof, pipkin, cross valve, infusion bottle and connect a kind of transfusion device that flexible pipe is formed;
