Abstract
The utility model discloses a drainage tube and comprises a tube body, of which an outofshape through hole is arranged on a side wall in the front of the tube body. The utility model can ensure the smooth attraction process and is suitable for the high vacuum suction. The drainage tube cannot easily blocked during the attraction process because the outofshape through hole is arranged on the drainage tube, for preventing the ischemia, putrescence and perforation of the absorbed parts of the tissue organ and ensuring the smooth attraction process.
Description
Technical field
This utility model relates to technical field of medical instruments, especially a kind of conduit that is applicable to negative pressure drainage.
Background technology
Drainage tube of the prior art is provided with the perforate of regular shape, drainage tube forms excessive negative pressure when directly being contacted by the drain district easily in by the drain district, sucking adjacent tissue's organ by the regular shape perforate on the drainage tube causes drainage tube to stop up easily, thereby the quilt that causes histoorgan holds the position, and serious consequences such as ischemia, necrosis and perforation take place, and influence drainage effect.
The utility model content
Technical problem to be solved in the utility model provides a kind of attraction process that guarantees and carries out, is applicable to the drainage tube that high negative pressure attracts smoothly.
This utility model comprises body, and the forward sidewall of body is provided with through hole in irregular shape.
This utility model can guarantee that the attraction process carries out smoothly and be applicable to that high negative pressure attracts.Because what be provided with on the drainage tube is through hole in irregular shape, so in the attraction process, be difficult for causing drainage tube to stop up, prevent that histoorgan from being held serious consequences such as position generation ischemia, necrosis and perforation, guarantee that whole attraction process carries out smoothly.
As improvement of the present utility model, the front end of body is provided with blind end.
The sealing of body front end then can utilize liquid in the through hole attractor in irregular shape that is provided with on the tube wall fully when drain, reduced the generation probability that drainage tube stops up.
Another kind of improved form of the present utility model is that the front end at body is provided with through hole in irregular shape.
The body front end is provided with through hole in irregular shape and has guaranteed that more the attraction process is smooth and easy.
As further improvement of the utility model, the front portion of body is provided with medical foam cover layer or medical sponge.
Medical foam cover layer between drainage tube and drain district or medical sponge can stop block derivated to enter or contact drainage tube with the adjacent tissue organ.And medical foam cover layer or medical sponge have good water penetration, have guaranteed the smooth drain of liquid.Simultaneously, because medical foam cover layer or medical sponge are distributed in surface, drain district equably, internal organs are held or pressurized and cause the generation of complication such as ischemia, necrosis, perforation when further effectively having prevented traditional negative pressure drainage.

Fig. 2 is the structural representation of another kind of embodiment of the present utility model.
Fig. 3 is the structural representation of the third embodiment of the present utility model.
Fig. 4 is the structural representation of the 4th kind of embodiment of the present utility model.
The specific embodiment
As shown in Figure 1, body 1 forward tube wall is provided with a plurality of through holes in irregular shape 2, and above-mentioned through hole 2 in irregular shape can be irregularly shaped for general polygon or other.Body 1 front portion is provided with the medical foam cover layer 3 of parcel body 1.
Be illustrated in figure 2 as another embodiment of the present utility model, the drainage tube of this structure and the structure of the drainage tube shown in Fig. 1 are basic identical.Its difference is that body 4 is provided with a blind end 5.
Be illustrated in figure 3 as the third embodiment of the present utility model, the drainage tube of this structure and the structure of the drainage tube shown in Fig. 1 are basic identical.Its difference is that the front end of body 6 is provided with a through hole 7 in irregular shape, and this through hole 7 is communicated with the tube chamber of body 6.
Be illustrated in figure 4 as the 4th kind of embodiment of the present utility model, the drainage tube of this structure and the drainage tube structure among Fig. 3 are basic identical.Its difference is that body 8 front portions do not wrap up the medical foam cover layer.
Certainly, the body in this utility model is not limited to pipe, also can be the body of other shapes such as square tube.The also available medical sponge of medical foam cover layer of the anterior parcel of body is replaced.
