Abstract
The invention discloses a medical three-way valve which comprises a valve and a valve spool. The valve spool is arranged in an inner cavity of the valve, the valve is fixedly connected with the valve spool by a turning handle, an intelligent chip is arranged in the turning handle, a control key is arranged on the turning handle, connectors are arranged on the left side, the right side and the lower side of the valve, and screw caps are connected onto the connectors and are fixedly sleeved on the connectors. Owing to the mode, the medical three-way valve has the advantages that the medical three-way valve is simple in structure, can be conveniently connected with another medical instrument and can be fixed reliably, the cost is reduced, the excellent sealing performance is guaranteed, the medical three-way valve can be used with the other medical instrument for intravenous injection or liquid or blood transfusion for a human body, high-speed transmission of injection is guaranteed, and the cleanliness of the injection can be guaranteed.
Description
Technical field
The present invention relates to medical instruments field, particularly relate to a kind of medical three-way valve.
Background technology
General and the supporting use of other medical apparatus and instruments of medical three-way valve is used as intravenous injection or transfusion and blood transfusion to human body, and its application at medical field is very extensive.
Present its sealing of medical three-way valve is not firm, and extraneous gas enters valve inner, is easy to injection is impacted, and reduces injection quality and transfusion speed.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of medical three-way valve, simple in structure, easy to connect, fixing reliable, reduced cost, guaranteed excellent sealing performance, can with the supporting use of other medical apparatus and instruments, to human vein injection or transfusion and blood transfusion, guarantee that the high speed of injection is carried, can guarantee the cleaning of injection simultaneously.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of medical three-way valve is provided, comprise: valve body and be arranged on spool in the body cavity, fixedly connected by steering handle between valve body and the spool, be provided with intelligent chip in the steering handle, steering handle is provided with control key, and the left and right sides and below are provided with joint on the valve body, be connected with screw-cap on the joint, the screw-cap fixed cover is located on the joint.
In a preferred embodiment of the present invention, described valve inner is provided with packing ring, and valve body and spool are by the washer sealing setting.
In a preferred embodiment of the present invention, between described joint and the screw-cap for being threaded.
In a preferred embodiment of the present invention, locking arranges between described joint and the screw-cap.
In a preferred embodiment of the present invention, induction connects between described control key and the intelligent chip.
In a preferred embodiment of the present invention, the joint of described left side and below is the female cone joint, and the joint on right side is the outer cone joint.
The invention has the beneficial effects as follows: the medical three-way valve of the present invention is simple in structure, easy to connect, fixing reliable, reduced cost, guaranteed excellent sealing performance, can with the supporting use of other medical apparatus and instruments, to human vein injection or transfusion and blood transfusion, the high speed that guarantees injection is carried, and can guarantee the cleaning of injection simultaneously.
Description of drawings
Fig. 1 is the structural representation of medical three-way valve one preferred embodiment of the present invention;
The labelling of each parts is as follows in the accompanying drawing: 1, valve body, 2, spool, 3, steering handle, 4, the female cone joint, 5, the outer cone joint, 6, screw-cap, 7, control key.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
See also Fig. 1, the embodiment of the invention comprises:
A kind of medical three-way valve comprises: valve body 1 and be arranged on spool 2 in valve body 1 inner chamber, and fixedly connected by steering handle 3 between valve body 1 and the spool 2.
The inside of described valve body 1 is provided with packing ring, and valve body 1 and spool 2 be by the washer sealing setting, has avoided gas the stockpiling of valve body 1 inside, and has prolonged the service life of valve body 1, can improve the flow velocity of injection simultaneously.
The left and right sides and below are provided with joint on the described valve body 1, and the joint of left side and below is female cone joint 4, and the joint on right side is outer cone joint 5.
Injection is input to valve body 1 inside by outer cone joint 5, exports from female cone joint 4 by the passage between valve body 1 and the spool 2 then.
Locking to be close at joint is connected to screw-cap 6, and screw-cap 6 fixed covers are located on the joint.Preferably, for being threaded, it connects simple, has reduced cost between joint and the screw-cap, and fixing reliable.
Be provided with intelligent chip in described steering handle 3, steering handle is provided with control key 7, and induction connects between control key 7 and the intelligent chip.
Press control key 7, intelligent chip startup work, steering handle 3 clockwise rotates, and forms confined space between valve body 1 and the spool 2, has avoided the existence of gas, guarantees that the high speed of injection is carried; Press control key 7 again, steering handle 3 rotates counterclockwise, and valve body 1 and spool 2 break away from, and the air in valve body 1 inner chamber and dirt are discharged, and guarantee the cleaning of injection.
The beneficial effect of the medical three-way valve of the present invention is:
Simple in structure, easy to connect, fixing reliable, reduced cost, guaranteed excellent sealing performance, can with the supporting use of other medical apparatus and instruments, to human vein injection or transfusion and blood transfusion, guarantee that the high speed of injection is carried, can guarantee the cleaning of injection simultaneously.
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes description of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
