Description
Technical field
This utility model relates to a kind of medical apparatus and instruments field, the slow pressure valve specifically on suction catheter, is more specifically medical negative pressure suction slow pressure valve automatically.
Background technology
On existing clinical medicine, suction catheter scope used very extensive, in the operation of sputum aspirator tube, cardiotomy suction pipe, splanchnocoel, the above-mentioned suction catheter such as suction catheter, fetal head suction catheter, neonate oral cavity attraction pipe all realizes attraction work by negative pressure, but due to the pressure in human body and the difference using position, suction catheter is easily caused can not effectively to attract liquid thing, or negative pressure inhales the drawback extremely causing tissue injury, cause secondary injury to patient, also cause the situation of clinical manipulation inconvenience to medical personnel.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and provides a kind of structure simple, easy to operate, effectively prevent the phenomenon of inhaling dead damage tissue and occurs maybe attracting the situation of liquid thing to occur.
For achieving the above object, this utility model adopts following technical scheme to realize, medical negative pressure suction is slow pressure valve automatically, primarily of: valve body, bonnet, stationary barrier, spool, spring form, and described valve body is that the bottom of its left and right sides of cylindrical structure is respectively arranged with import and outlet; Described import and outlet are interconnected in valve body; The upper inside wall of described valve body is provided with annular boss, and the top of boss is provided with female thread; Described stationary barrier is round pie, it is evenly distributed with six air pressure balance mouths and a circular groove; The bottom of described bonnet is provided with the external screw thread mutually mated with valve body female thread, and its crown center position is provided with spool bore; Described spool bore is upper narrow lower large bellmouth; Described spool is upper narrow lower large tapered pole, is provided with spring fixing groove bottom it, and its top is provided with 5 millimeters high cylindrical by compression leg; Described groove is positioned at the circle centre position of stationary barrier.
Aforesaid medical negative pressure suction is slow pressure valve automatically, and it is characterized in that: described spring one end is placed on groove, the other end is connected with the spring fixing groove bottom spool.
Aforesaid medical negative pressure suction is slow pressure valve automatically, it is characterized in that: described valve body and bonnet are interconnected and fixed by screw thread.
This utility model has: structure is simple, easy to operate, effectively prevent the advantage of inhaling the dead phenomenon damaging tissue and occurring maybe attracting the situation of liquid thing to occur.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is this utility model stationary barrier structural representation;
Fig. 3 is this utility model bonnet structural representation;
Fig. 4 is this utility model valve core structure schematic diagram.
Detailed description of the invention
Illustrate below in conjunction with accompanying drawing, this utility model is further elaborated.
Fig. 1-Fig. 4 is optimal way of the present utility model, which show medical negative pressure suction slow pressure valve automatically, primarily of: valve body 1, bonnet 2, stationary barrier 3, spool 4, spring form, and described valve body 1 is that the bottom of its left and right sides of cylindrical structure is respectively arranged with import and outlet; Described import and outlet are interconnected in valve body; The upper inside wall of described valve body 1 is provided with annular boss 11, and the top of boss 11 is provided with female thread; Described stationary barrier 3 is round pie, it is evenly distributed with six air pressure balance mouths 6 and a groove 7; The bottom of described bonnet 2 is provided with the external screw thread mutually mated with valve body 1 female thread, and its crown center position is provided with spool bore 8; Described spool bore 8 is upper narrow lower large bellmouth; Described spool 4 is upper narrow lower large tapered pole, is provided with spring fixing groove 9 bottom it, and its top is provided with 5 millimeters high cylindrical by compression leg 10; Described groove 7 is positioned at the circle centre position of stationary barrier 3.
Aforesaid medical negative pressure suction is slow pressure valve automatically, and it is characterized in that: described spring one end is placed on groove 7, the other end is connected with the spring fixing groove 9 bottom spool.
Aforesaid medical negative pressure suction is slow pressure valve automatically, it is characterized in that: described valve body 1 is interconnected and fixed by screw thread with bonnet 2.
During use, the import of valve body 1 and hose connection, flexible pipe inserts in patient body, outlet is connected with attractor, and when air pressure balance, spool position is constant, when air pressure is uneven, spool moves down, and such air pressure enters valve body from the space around spool, carries out air pressure balance, if spool jam, can press...with one's finger dynamic by compression leg 10, carry out the position adjustment of spool, therefore avoid the generation of inhaling and extremely maybe cannot draw liquid thing phenomenon.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be treated as protection domain of the present utility model.
