Abstract
The utility model belongs to a technical field of medical appliance, in particular to a three way cock for pressure monitoring, pressure testing of myelocentesis, flow measurement sampling or multi-path transfusion. The utility model comprises a handle, a spool and a valve seat, wherein the handle is arranged on the spool and the spool is arranged in the valve seat. Three channels are arranged on the valve seat, and a socket is connected with the bottom of the valve seat. The socket is fixedly connected with the spool, and a bottom board of the socket is jointed with the bottom of the valve seat. The utility model has the characteristics of simple structure, convenient employment and good sealing property. The bottom of the valve seat is connected with the socket, and the socket is fixedly connected with the spool, the bottom board of the socket is jointed with the bottom of the valve seat, thereby the structure has good sealing property, and the spool and the socket integrate as one piece, therefore avoiding the defect of slidable detachment of the valve seat and the spool, being convenient for the product inspection, and creating good conditions for ensuring the application safety.
Description
Technical field
This utility model belongs to technical field of medical instruments, particularly relates to and/or three-way cock that pressure monitoring, thecal puncture pressure measurement, pneumatic measurement sampling or multichannel transfusion are used.
Background technology
In the prior art, giving emergency treatment to a patient in the hospital needs multichannel transfusion or multiple treatment and observations such as pressure monitoring, thecal puncture pressure measurement and pneumatic measurement sampling, this uses three-way cock often, on patient body, insert many pipelines to reduce, can reasonably arrange pipeline, be usually used in implementing central venous pressure monitoring.Three-way cock is made up of valve seat, spool and three-way pipeline, and it is to be made by medical macromolecular materials, have transparent, general, reliable, be easy to characteristics such as identification, adopt arrow clearly to indicate selected passage usually; Colour coding helps debating the knowledge multiloop loop system, and blueness is used for vein, and redness is used for tremulous pulse, and white and yellow are used for other pipeline.The structure that three-way cock is transparent can increase transfusion safety, helps observing the aerofluxus situation.The three-way cock processing ease needn't disconnect connection during ALT-CH alternate channel, and passage is atomic break period, and does not produce eddy current, can reduce thrombotic danger.When spool in the manufacture process has the micropore that is difficult to avoid,, can't check rejecting because the bottom of valve seat is an one with seat, have liquid in the use and ooze in slowly long-pending being present, overflow three-way cock at last, wasted medicinal liquid, if accurately transfusion influences therapeutic effect.Valve seat and spool all are mouldings in addition, will rotate in the use, so both can not be tight fits, have easily that string is moving up and down, especially repeatedly rotate post gap and increase, even produce the spool valve seat phenomenon that slips away; In use, cause three-way cock to use, cause new harm to patient as the spool valve seat that slips away.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, easy to use, spool and the compact three-way cock of valve seat.
The purpose of this utility model is to adopt such technical solution to realize: comprise handle, spool and valve seat, described handle is installed on the spool, described spool is installed in the valve seat, described valve seat is provided with three passages, the lower end that it is characterized in that described valve seat is connected with base, this base is fixedlyed connected with spool, and the base plate of described base and the bottom of valve seat fit.
Because the lower end of the valve seat that this utility model adopts connects base, base is fixedlyed connected with spool, the structure that the base plate of described base and the bottom of valve seat fit, its good airproof performance, after spool and base fuse, eliminated the defective that slipping away appears in valve seat and spool, the examination and test of products is convenient, for ensureing the advantage of having created safe in utilization.

The specific embodiment
With reference to accompanying drawing 1: this utility model comprises handle 1, spool 7 and valve seat 4, described handle 1 is installed on the spool 7, described spool 7 is installed in the valve seat 4, described valve seat 4 is provided with three passages 2,3,8, the lower end of described valve seat 4 is connected with base 6, this base 6 is fixedlyed connected with spool 7, and the base plate 5 of described base 6 fits with the bottom of valve seat 4; Because base 6 adopts fixed seal connection with spool 7, the conduction status of passage 2,3,8 can be regulated and be controlled by the handle 1 of spool 7 during use, described base 6 adopts plastic material injection molded, gas or the liquid status transmission in passage 2,3,8 can direct observation, and the sealing property of valve seat 4 also is significantly improved, thereby provides certain guarantee for safe transport gas, liquid.
