Abstract
The utility model provides a disposable medical four-way valve, which comprises a valve body and a valve core, wherein the valve core is provided with a control handle, and two inlets and one outlet which are all communicated with the valve core are formed on the valve body. The utility model is characterized in that one outlet which is communicated with the valve core is additionally arranged onthe valve body for forming the four-way valve. The utility model changes the original three-way valve into the four-way valve, adds the liquid transfusion outlet, reduces the pressure of the liquid onblood vessels through flow diversion, avoids outward liquid seepage of the blood vessels caused by overpressure of injection liquid, can meet the requirement of liquid transfusion quantity in unit time in clinics, can be widely used for the aspects such as diagnosis and the treatement of clinic intervention, application of reducing intracranial hypotension medicine and the like, and has the advantages of simple structure and good working performance.
Description
Technical field
This utility model provides a kind of disposable medical to use cross valve, belongs to technical field of medical instruments.
Background technology
Injecting certain amount of fluid in the certain hour, is modern clinical a kind of diagnosis, therapeutic modality commonly used.But this sometimes powerful liquid injects because of its pressure has exceeded the holding capacity of blood vessel wall to the lateral pressure of human vas wall, and the patient's blood vessel wall holds can't stand that this pressure causes that medicinal liquid exosmoses, and causes diagnosing, treating the interruption of operation.So the clinical medical apparatus that needs this fluid pressure of a kind of energy decomposition is urgently alleviated this pressure by multichannel shunting transfusion, to reach the purpose of diagnosis, treatment.And the design of traditional three-way valve is the transfusion principle of a kind of " two advance goes out ", can't satisfy dividing potential drop, the shunting transfusion form of " one-in-and-two-out " of this medical treatment requirement.
The utility model content
The purpose of this utility model provides a kind ofly can overcome above-mentioned defective, satisfy clinical unit's time amount of infusion, and the disposable medical that can avoid blood vessel to cause that because of injection pressure is excessive medicinal liquid exosmoses use cross valve.Its technical scheme is:
Comprise a valve body and the spool that is provided with joystick, wherein valve body is provided with two imports and outlet that all is communicated with spool, it is characterized in that: set up an outlet that is communicated with spool on valve body, structure is a cross valve.
Described disposable medical uses cross valve, is equipped with the aseptic nut of terminal shutoff in each import, in order to guarantee the aseptic of import department.
Described disposable medical uses cross valve, and equal suit one coupling nut is gone up in each outlet, the terminal no cap that is provided with terminal shutoff of outlet, and in order to guaranteeing the aseptic of exit, coupling nut is in order to reinforce being connected of tube for transfusion and outlet.
This utility model compared with prior art has following advantage:
1, need open two venous accesses by clinical, liquid has reduced pressure to blood vessel because of shunting, avoid blood vessel because of the excessive intravenous extravasation that causes of injection pressure, clinical unit's time amount of infusion requirement can be satisfied, the aspects such as application of the diagnosis of clinical intervention and treatment, reduction intracranial pressure medicine can be widely used in;
2, because dividing potential drop shunting transfusion then can effectively be protected patient's blood vessel, for treatment is in the future provided convenience;
3, by the control valve of clinical needs, can realize " one-in-and-two-out ", " two advance one goes out ", " two advance two goes out ", one-object-many-purposes by control drop bottle puncture needle or transfusion needle;
4, simple in structure, excellent working performance.
Description of drawings
Fig. 1 is the structural representation of utility model embodiment.
Among the figure: 1, valve body 2, spool 3, import 4, outlet 5, aseptic nut 6, coupling nut 7, no cap 8, joystick
The specific embodiment
In the embodiment shown in fig. 1: comprise a valve body 1 and the spool 2 that is provided with joystick 8, wherein valve body 1 is provided with two imports 3 and two outlets 4 that all are communicated with spool 2, be equipped with the aseptic nut 5 of a terminal shutoff in each import 3, in order to guarantee the aseptic of import 3 places, equal suit one coupling nut 6 in each outlet 4, export the no cap 7 that 4 ends are provided with terminal shutoff, in order to guaranteeing the aseptic of outlet 4 places, coupling nut 6 is in order to reinforce tube for transfusion and to export 4 be connected.
