Background technology
Existing Medical wounded surface negative pressure therapeutic devices, generally refer to washing wound surface-negative-pressure sealed drainage cushion special, this cushion special has the function of washing wound surface and negative pressure drainage concurrently, its structure comprises drain, syringe pipe and medical drainage material, for easy to use, drainage tube and syringe pipe are divided into two sections, wherein, drainage tube is divided into external drainage tube and built-in drainage tube, and built-in drainage tube is partly or entirely wrapped in and among medical drainage material and on wall pipe, has multiple side openings.Among built-in drainage tube is all wrapped in medical drainage material time, external drainage tube front end is embedded in medical drainage material by one, and the plug-in type flow sub that interface exposes to medical drainage outer surface is connected with built-in drainage tube is dismantled and assembled, external drainage tube rear end connects negative pressure source.Syringe pipe similar, and built-in syringe pipe is wrapped in medical drainage material, front end inserts in built-in drainage tube or stretch out with medical drainage material inner surface outside, built-in syringe pipe rear end adopts one to be embedded in medical drainage material equally, and the plug-in type flush-through connection that interface exposes to medical drainage outer surface is connected with external syringe pipe removably.But built-in flow sub that can not elastic telescopic and drainage tube, under condition of negative pressure, because the effect of air atmospheric pressure can form certain contention effect to wound surface, cause Principle of Pain, even affect the healing of patient's wound surface.And joint only plays interconnect function.
Utility model content
The purpose of this utility model, is to provide a kind of negative pressure drainage joint.
The solution that this utility model solves its technical problem is: a kind of negative pressure drainage joint, and it comprises columned joint body, each tube wall of described joint body is provided with the flexible groove of multiple tracks and at least one negative pressure drainage side opening.
As the further improvement of technique scheme, the surrounding wall of described joint body is provided with the negative pressure drainage hole of multiple connection joint bodies inside, and described negative pressure drainage hole is arranged on the cell wall between adjacent flexible groove.
As the further improvement of technique scheme, described joint body is multiple-pass joint, and the negative pressure drainage side opening on described joint body sidewall can be connected with drainage tube.
As the further improvement of technique scheme, the degree of depth of described flexible groove is 2/3rds of structural body sidewall thickness.
As the further improvement of technique scheme, the upper surface of described joint body is provided with flushing hole, described flushing hole can be connected with syringe pipe, and the lower surface of joint body is provided with the flexible groove of multiple tracks, and the cell wall between adjacent flexible groove is provided with multiple negative pressure drainages hole.
As the further improvement of technique scheme, the cross section of described flexible groove is the one in rectangle, ellipse or triangle.
The beneficial effects of the utility model are: this utility model by being provided with the flexible groove of multiple tracks and at least one negative pressure drainage side opening on each tube wall of joint body, joint body is being subject to External Force Acting power, due to the telescopic action of flexible groove, joint body can not squeeze patient's skin firmly, reduce patient's immoderation, and connect built-in drainage tube by negative pressure drainage side opening, in the time not connecting built-in drainage tube, negative pressure drainage side opening plays negative pressure drainage effect.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in this utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described.Obviously, described accompanying drawing is a part of embodiment of the present utility model, rather than whole embodiment, and those skilled in the art is not paying under the prerequisite of creative work, can also obtain other designs and accompanying drawing according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of this utility model while connecting built-in drainage tube;
Fig. 3 is the structural representation of the lower surface of structural body in this utility model.
The specific embodiment
Below with reference to embodiment and accompanying drawing, the technique effect of design of the present utility model, concrete structure and generation is clearly and completely described, to understand fully the purpose of this utility model, feature and effect.Obviously; described embodiment is a part of embodiment of the present utility model, rather than whole embodiment, based on embodiment of the present utility model; other embodiment that those skilled in the art obtains under the prerequisite of not paying creative work, all belong to the scope that this utility model is protected.In addition, all connection/annexations of mentioning in literary composition, not singly refer to that member directly joins, and refer to and can, according to concrete performance, connect auxiliary by adding or reducing, and form more excellent draw bail.
With reference to Fig. 1 ~ Fig. 3, a kind of negative pressure drainage joint, it comprises columned joint body 1, each tube wall of described joint body 1 is provided with the flexible groove 2 of multiple tracks and at least one negative pressure drainage side opening 3.By be provided with the flexible groove 2 of multiple tracks and at least one negative pressure drainage side opening 3 on each tube wall of joint body 1, joint body 1 is being subject to External Force Acting power, due to the telescopic action of flexible groove 2, joint body 1 can not squeeze patient's skin firmly, reduce patient's immoderation, and connect built-in drainage tube by negative pressure drainage side opening 3, in the time not connecting built-in drainage tube, negative pressure drainage side opening 3 plays negative pressure drainage effect.
As the further improvement of technique scheme, the surrounding wall of described joint body 1 is provided with the negative pressure drainage hole 4 of multiple connection joint bodies 1 inside, and described negative pressure drainage hole 4 is arranged on the cell wall between adjacent flexible groove 2.Such setting, not only realizes negative pressure drainage by built-in drainage tube, and also, by the negative pressure drainage hole 4 on joint body 1, joint body also can be realized negative pressure drainage, improves the effect of negative pressure drainage.
