The case can promote the front and back in the inner chamber of horizontal pipe, when the operation to singlehanded forefinger and middle finger centre gripping are in the upper and lower both sides of valve body vertical duct with horizontal union coupling position, and the case is pushed to the thumb, can realize opening and closing of cross valve. The utility model has the advantages of being simple in structure and convenient in operation, the leakproofness is good, and economy is effective, uses safe and reliable.
Description
Technical field
This utility model relates to medical apparatus and instruments, particularly relates to a kind of drainage bag fluid cross valve.
Background technology
In prior art, drainage bag is mainly used in the drain of patient's body fluid or tissue exudates, drains in drainage bag during drain by drainage catheter by body fluid, and after drainage bag is full, liquid is discharged by the liquid valve that can arrange bottom drainage bag.
Existing liquid valve comprises a hollow valve body be connected with drainage bag, is provided with inlet in one end of valve body, is provided with liquid outlet at the other end of valve body, is provided with protective cap at the liquid outlet of valve body.During work, dial lower protective cap, just by the liquid emptying in drainage bag, protective cap can be put and just can continue drain.Its weak point is: this liquid valve needs bimanualness to close and to open, and due to normal containing pathogenic bacteria in patient's body fluid, when held by both hands threshold switch, easily made dirty by hands, has larger risk to operator; In addition, adopt the mode of bimanualness convenient not.
Summary of the invention
The purpose of this utility model is to provide a kind of simple to operate, drainage bag fluid cross valve that switch is convenient, healthy.
The purpose of this utility model is achieved in that
A kind of drainage bag fluid cross valve, comprise valve body and spool, feature is: valve body is made up of vertical duct and transverse pipe, transverse pipe and vertical duct cross are also connected as a single entity, inlet is provided with in the upper end of vertical duct, liquid outlet is provided with in the lower end of vertical duct, the inner chamber of transverse pipe and the inlet of vertical duct, liquid outlet is connected respectively, a spool matched with the inner chamber of transverse pipe is inserted with in transverse pipe, the middle front part sidewall of spool is provided with annular groove, at spool by valve handle end, the sidewall of adjacent annular groove is provided with the O-ring seal integrated with spool, the length of spool will grow 3 ~ 25mm compared with the length of transverse pipe, the external diameter of annular groove is 1/10 ~ 4/5 times of the internal diameter of vertical duct, the length of annular groove is 1/2 ~ 3/2 times of the internal diameter of vertical duct, external diameter 0 ~ the 1mm larger than the internal diameter of transverse pipe of O-ring seal, the length of O-ring seal is 1 ~ 2 times of the internal diameter of vertical duct.
Spool can in the inner chamber of transverse pipe before and after promote, when transfer to valve handle backward or push spool from the external part before spool, spool is pulled to the rear end of inner chamber of transverse pipe time, annular groove and inlet, liquid outlet are connected simultaneously, and fluid course is opened; When pressing forward valve handle, when spool being pushed to the front end of inner chamber of transverse pipe, annular groove and inlet, liquid outlet staggered positions, fluid course is closed.
During utility model works, inlet one end of valve body is connected with bottom drainage bag; Length due to spool is greater than the length of the transverse pipe of valve body, outside the transverse pipe of the extended valve body in front end of spool, therefore can press forward valve handle, backward dial-out valve handle or push spool from the external part before spool, spool is slided in transverse pipe, when spool pushes the front end of the inner chamber of transverse pipe to, annular groove and inlet, liquid outlet are connected simultaneously, and the liquid now in drainage bag can flow out; When spool pushes the rear end of the inner chamber of transverse pipe to, annular groove staggers with inlet, liquid outlet position, and fluid course has been blocked in O-ring seal, and the liquid now in drainage bag can not flow out; When operating, be clamped in the both sides up and down of valve body vertical duct and transverse pipe connecting portion with singlehanded forefinger and middle finger, thumb pushes spool, can realize the opening and closing of cross valve.Compared with prior art, this utility model structure is simple, easy to operate, good airproof performance, and economical and effective is safe and reliable.
Accompanying drawing explanation
Fig. 1 is the structural representation of valve body;
Fig. 2 is the structural representation of spool;
Fig. 3 is the view that this utility model is in when fluid course is opened;
Fig. 4 is the view that this utility model liquid is in when fluid course is closed.
Detailed description of the invention
Contrast accompanying drawing below in conjunction with embodiment this utility model is described in further detail.
As Fig. 1, shown in 2, drainage bag fluid cross valve comprises valve body 3 and spool 7, valve body 3 is made up of vertical duct 2 and transverse pipe 4, transverse pipe 4 is with vertical duct 2 cross and be connected as a single entity, inlet 1 is provided with in the upper end of vertical duct 2, liquid outlet 5 is provided with in the lower end of vertical duct 2, the inner chamber 6 of transverse pipe 4 and the inlet 1 of vertical duct 2, liquid outlet 5 is connected respectively, a spool 7 matched with the inner chamber 6 of transverse pipe 4 is inserted with in transverse pipe 4, the middle front part sidewall of spool 7 is provided with annular groove 9, at spool 7 by valve handle 10 end, 9 sidewalls of adjacent annular groove are provided with the O-ring seal 8 integrated with spool, the length of spool 7 will long 10mm compared with the length of transverse pipe 4, the external diameter of annular groove 9 is 1/2 times of the internal diameter of vertical duct 2, the length of annular groove 9 is 3/4 times of the internal diameter of vertical duct 2, the external diameter 0.2mm larger than the internal diameter of transverse pipe 4 of O-ring seal 8, the length of O-ring seal 8 is 3/2 times of the internal diameter of vertical duct 2.
