Second infall cutting seam 221 open inserts detector and takes out expectorant pipe with detected air pressure, MDI, gas, temperature or insertion
100 to take out expectorant, and because first cuts seam 211 and second open and cut open and stitch 221 in cross-over configuration, makes the first flap valve part 21
With the raising direction and can interfere with each other of the second flap valve part 22, thus avoid the first flap valve part 21 and the second flap valve part 22
Raise and make a slip of the tongue big, stitch 211 and second effectively to prevent gas connecting tube 1 within from cutting open from first and cut seam 221 open
Infall leak, with Non-return air valve module 2, there is excellent ground ease of use and gas reaching medical joint 10
Body prevents letting out property.
It addition, as shown in Figures 1 to 5, ring wall 213 wears and amplexiforms in the first body 11, backstop bulge loop 214
Backstop mutual with ora terminalis 113 is spacing, and the second disk body 222 is layered on top of each other with the first disk body 212 and amplexiforms, each fin
223 fasten in respectively running through groove 215 and transmission groove 114, and projecting block 224 is spacing with the first mutual backstop of body 11,
The first flap valve part 21 and the second flap valve part 22 is made to be firmly installed and be closed in connected entrance 111；Further, each salient point
2121 are sticked in each groove 2221, so prevent the first disk body 212 relative to the second disk body 222 off normal or rotation,
To strengthen the first flap valve part 21 and binding ability of the second flap valve part 22.
Furthermore, as shown in Figures 1 to 5, medical joint 10 further includes the first roll tube 3 and the second roll tube 4,
First roll tube 3 is connected to first interface 112 and can rotate relative to the first body 11, and the second roll tube 4 is even
It is connected to the second interface 121 and can rotate relative to the second body 12, to facilitate the first roll tube 3 or second to rotate
When pipe 4 connects other exterior tubular body, if accidentally touching, moving or rotate to exterior tubular body, the also company of will not interfere with
The position of adapter 1, to promote the safety in utilization of medical joint 10.
Refer to shown in Fig. 6, the medical joint of the present invention 10 and another embodiment of Non-return air valve module 2, Fig. 6
Embodiment roughly the same with the embodiment of Fig. 1 to Fig. 5, but the embodiment of the embodiment of Fig. 6 and Fig. 1 to Fig. 5
Difference is that the first disk body 212 and the second disk body 222 are respectively towards protruded away from connected entrance 111 direction
Convex surface dish 23.
Describe in detail as follows, detector or to take out expectorant pipe be that to insert connecting tube 1 by connected entrance 111 internal, so the
One disk body 212 and the second disk body 222 are respectively towards the convex surface dish 23 protruded away from connected entrance 111 direction, make first
Cut seam 211 and second open and cut raising direction and detector or taking out the direction of insertion of expectorant pipe in the same direction of seam 221 open, more square
Just pilot detector or take out expectorant pipe to insert connected entrance 111 internal, to improve medical joint 10 and Non-return air valve module
The ease of use of 2.
Wherein, each convex surface dish 23 can be towards the plano-convex dish protruded away from connected entrance 111 direction or concavo-convex dish, this enforcement
Each convex surface dish 23 of example is concavo-convex dish, but is not limited system.
Certainly, the present invention also can have other various embodiments, without departing substantially from present invention spirit and the feelings of essence thereof
Under condition, those of ordinary skill in the art work as can make various corresponding change and deformation according to the present invention, but
These change accordingly and deform the protection domain that all should belong to appended claims of the invention.
