Embodiment 1
Drainage system provided by the utility model, including：Drainage tube 100 and drainage bag, the drainage bag include external connection end
200, the one end of drainage tube 100 is built in human body, and the other end can link together with the external connection end 200 of drainage bag, so as to shape
Connection in adult body between drainage bag, the link position of the drainage tube 100 and drainage bag are respectively arranged with the first fastening
Structure and the second fastening structure, after the first fastening structure and the second fastening structure fastening, for preventing the drainage bag
External connection end 200 departs from the drainage tube 100.When needing to carry out surgical drainage to patient, it is necessary to by built in the one end of drainage tube 100
In in human body, the other end is connected with the external connection end 200 of drainage bag, is then matched somebody with somebody by the first fastening structure and the second fastening structure
Close, drainage tube 100 is fixed together with drainage bag, prevents drainage bag in use easily from drainage so as to reach
The technique effect to be come off on pipe 100.
Specifically, as shown in figure 1, the external connection end 200 is flexible, the external connection end 200 is by deformation after external force, outside
Power removes rear shape and recovered, and first fastening structure is to be arranged on the first ring-type at the mouth of pipe outer wall of the drainage tube 100
Wedge shaped element 310, second fastening structure be arranged at the inwall of external connection end 200 of the drainage bag with the first ring-type wedge
Second ring-type wedge shaped element 320 corresponding to shape unit 310, so that the first ring-type wedge shaped element 310 enters the external connection end
After 200,320 mutual clamping of the first ring-type wedge shaped element 310 and the second ring-type wedge shaped element.Existing drainage bag it is external
End 200 is the structure of aciculiform, when in use, is directly inserted into drainage tube 100, because the material of drainage tube 100 has
Elasticity, so the drainage bag being plugged on thereon can be connected with drainage tube 100, but frictional force connection is uniquely relied on therebetween
If, it is highly unstable, especially drainage bag is necessarily placed at the place lower than patient drainage location, so being moved in patient
Leave in the case of body, drainage tube 100 may be torn, the connection end of such drainage tube 100 and drainage bag, will be occurred opposite
The movement tendency in direction, at leisure, the external connection end 200 of drainage bag will come off from drainage tube 100, so, the present embodiment leads to
Cross at the link position of drainage tube 100 and drainage bag and set the first ring-type wedge shaped element 310 and the second ring-type wedge shape single respectively
Member 320, after the first ring-type wedge shaped element 310 is injected into external connection end 200, after crossing the second ring-type wedge shaped element 320, the second ring-type
The deformation of wedge shaped element 320 recovers, and outwards tears drainage tube 100, and the first ring-type wedge shaped element 310 can be single with the second ring-type wedge shape
First 320 clampings, so, drainage tube 100 are bigger with respect to power is pullled with drainage bag both ends, the first ring-type wedge shaped element 310 and the
Two ring-type wedge shaped elements 320 block nearer.
Preferably, as shown in Fig. 2 the drainage tube 100 can include supervisor 110 and tap 120, the shunting connect
First 120 include multiple external ends, and the external end is used to be in communication with the outside, and the supervisor 110 and tap 120 are screw thread
Connection.The quantity at external end can effectively be increased with the connected mode of tap 120 using supervisor 110, conveniently perform the operation into
Capable and postoperative nursing.Drainage tube 100 often links together with drainage bag under normal circumstances, but if necessary by
Drainage tube 100 is passed through decoction into human body, then needs to extract drainage bag, so not only very troublesome, and swapping process is easy
Bacterium is entered into the human body, cause patient to infect, so setting mozzle to include tap 120, in tap 120
What one external end was connected with drainage bag, and other joints can be used as the input of decoction, doctor can pass through note
Liquid liquid medicine injection into drainage tube 100 is penetrated, it is very convenient.
Plug is provided with the side wall at the external end, the plug is used to block the external end being not used by.For
Prevent extraneous air from entering into the human body, the tissue in human body polluted, plug is provided with the side wall at external end,
Plug includes connecting portion and stop part, and connecting portion and tap 120 are structure as a whole, and is elastomeric material, and stop part can be with
Eye-splice is in the opening at external end, so as to which external end resistance be blocked.
As in Figure 3-5, the drainage system can include fixation kit.Because finish the implant surgery of drainage tube 100
Patient, a part of drainage tube 100 can be left in vitro, patient may drive drainage tube 100 to outward transport when moving body
It is dynamic, cause the built-in end of drainage tube 100 to deviate the position set, or directly take drainage tube 100 out of human body, such patient
Also need to re-start drainage tube 100 and perform the operation, the burden taken to patient in extra economy and body.So drainage dress is set
To put including fixation kit, fixation kit is used to fix drainage tube 100, so as to prevent drainage tube 100 from relative motion occurs with human body,
The fixation kit includes paste section and first fixed structure, and the paste section also includes release layer, and release layer is arranged at viscous
Below paste layer, to protect adhered layer.Release layer can select release liners, and the upper surface of release layer is scribbled for preventing release liners
The silicone oil Nian Jie with adhered layer, release layer can be used for protecting adhered layer.Using during fixed structure, it is necessary to which first release layer is taken off
Rise, then the fixed structure is adhered on patient body by adhered layer, so as to prevent that it is relative that fixed structure and human body from occurring
Motion.Be provided with the second fixed structure corresponding with first fixed structure on the drainage tube 100, the first fixed structure with
Second fixed structure coordinates, and for preventing the drainage tube 100 from relative motion occurs with fixation kit, will draw so as to reach
The part of flow tube 100 is fixed on fixed structure, prevents drainage tube 100 from departing from out of human body.
Specifically, the first fixed structure includes groove 410 corresponding with the drainage tube 100, can be by drainage tube
100 are vertically disposed in groove 410, and recess 411 is arranged at intervals with the groove 410, is correspondingly arranged on the drainage tube 100
There is convex portion 412, after drainage tube 100 is put into groove 410, the projection on drainage tube 100 can be trapped in the recess in groove 410
In 411, so, when drainage tube 100 is by involve power along its length, projection is stuck in recess 411, to drainage tube 100
Obstruction is caused, prevents drainage tube 100 that relative motion occurs.
The cross section of the groove 410 can be circular arc, and the central angle of the circular arc is more than 180 °.Because drainage tube 100
Generally use is all High performance polyolefin thermoplastic elastomer, is to have certain elasticity in itself, the central angle of circular arc is more than
180 °, then the A/F of groove 410 is just by less than between drainage tube 100, so can be with when drainage tube 100 are placed
Drainage tube 100 is incorporated into groove 410 by way of extruding, be so less than drainage tube using the A/F of groove 410
100 diameter, it can prevent drainage tube 100 from departing from the fixed structure from the opening of groove 410.
Preferably, the first fixed structure includes groove lid 420, and the groove lid 420 is rotatablely connected with the one end of groove 410,
The groove lid 420 is respectively arranged with clamping structure with the other end of groove 410, after drainage tube 100 is placed on into groove 410, rotates
Groove lid 420, groove lid 420 is set to be covered in the opening of groove 410, clamping structure can be through hole and column, through hole is buckled in vertical
On post, frictional force therebetween is enough to ensure that the fastness that groove lid 420 is closed.
