Abstract
The utility model discloses a kind of anti-blocking peritoneal cavity drainage tubes, including drainage head, the front end of drainage head is cambered surface, the front end of drainage head is provided with front aperture, side wall is provided with side opening, spaced external groove and inner groovy are respectively arranged in the outer wall and inner wall of drainage head, side opening is located on the common wall of external groove and inner groovy, i.e. side opening is hidden in external groove, in drainage process, even if tissue is close to drainage head outer wall, since external groove is more narrow, side opening will not be caused to block, and, inner groovy makes the inner wall out-of-flatness of drainage head, drainage head is squeezed to axle center, even if the main channel closing in drainage head, inner groovy remains able to form drainage channel, ensure that drainage is smoothed out, drainage efficiency can be effectively improved, reduce patient's pain.
Description
Technical field
The utility model is related to a kind of medical instrument, particularly a kind of peritoneal cavity drainage tube.
Background technology
Peritoneal cavity drainage tube of the prior art is silica gel pipe, tube head and tube wall is provided with conduction hole, in negative pressure drainage
In the process, tissue is close to drain pipe outer wall, and conduction hole is easily blocked by tissue, and then negative pressure in pipe is caused constantly to increase
Greatly, drainage tube gradually becomes flat, and last flat drainage inside pipe wall is close to thoroughly block, and just needs replacing drainage in this case
Pipe drains again, time-consuming and laborious, also increases the pain of patient.
The patent document of Publication No. " CN204446916U " discloses a kind of anticlogging peritoneal cavity drainage tube of band strainer,
The technical solution adopted is that：Strainer is set in the side opening of drainage tube, prevents large-scale block from blocking pipeline, but its structure is answered
It is miscellaneous, moreover, clot, tissue for coming off etc. are attached on strainer, the problem of blocking strainer is further brought, is not also solved
Tissue is close to blockage problem caused by drainage tube.
The patent document of Publication No. " CN202951108U " discloses a kind of peritoneal cavity drainage tube, the technical solution used
It is：The circle small pipeline along length direction is provided in tube wall, small pipeline forms capillary phenomenon, generates certain negative pressure, not only
A small amount of thin body fluid can be drained away, and small pipeline close-packed arrays also play a supporting role to drainage tube wall, have
Effect prevents drainage tube to be crushed and gives a discount with drainage tube, but due to draining tube extrusion molding, tube wall is relatively thin, increases the difficulty of processing
Degree is also close to blockage problem caused by drainage tube without solving tissue.
Invention content
For overcome the deficiencies in the prior art, the utility model provides a kind of anti-blocking abdominal cavity that will not be blocked by tissue
Drainage tube.
Technical solution is used by the utility model solves its technical problem：
A kind of anti-blocking peritoneal cavity drainage tube, including drainage head, the front end of the drainage head is cambered surface, before the drainage head
End is provided with front aperture, and the side wall of drainage head is provided with side opening, if the outer wall of the drainage head is provided with arterial highway along its length
The external groove of arrangement, the side opening are located in the external groove, the equidistant annular arrangement of external groove.
If the inner wall of the drainage head is provided with the inner groovy that arterial highway arranges along its length, the equidistant ring of inner groovy
Shape arranges.
The external groove and inner groovy are alternatively arranged, and the side opening is located on the common wall of the external groove and inner groovy.
The section of the external groove is V-arrangement.
The beneficial effects of the utility model are：The utility model is respectively arranged with interval row in the outer wall and inner wall of drainage head
The external groove and inner groovy of row, side opening are located on the common wall of external groove and inner groovy, i.e., side opening is hidden in external groove, is being drawn
During stream, even if tissue is close to drainage head outer wall, since external groove is more narrow, tissue is not likely to enter narrow
External groove in, side opening will not be caused to block, moreover, inner groovy makes the inner wall out-of-flatness of drainage head, drainage head is squeezed to axle center,
Even if the main channel closing in drainage head, inner groovy remain able to form drainage channel, it is ensured that drainage is smoothed out, can be effective
Drainage efficiency is improved, reduces patient's pain.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the sectional view of the utility model.
Specific embodiment
With reference to Fig. 1, Fig. 2, a kind of anti-blocking peritoneal cavity drainage tube is described to draw including drainage head 1 by medical silica gel extrusion molding
The front end for flowing head 1 is cambered surface, and front aperture 2 is provided in the front end of the drainage head 1, and the side wall of drainage head 1 is provided with side opening 3,
If the outer wall of the drainage head 1 is provided with the external groove 4 that arterial highway arranges along its length, the side opening 3 is located at the external groove 4
It is interior, if the inner wall of the drainage head 1 is provided with the inner groovy 5 that arterial highway arranges along its length.The section of the external groove 4 is narrow
Small V-arrangement, the section of inner groovy 5 is by the diminishing trapezoidal shape in export-oriented axle center.
The 4 equidistant annular arrangement of external groove, the 5 equidistant annular arrangement of inner groovy（I.e. in terms of section, external groove
4th, inner groovy 5 is equiangularly arranged as dot using the center of circle of drainage head 1）, the external groove 4 and inner groovy 5 be alternatively arranged, the side
Hole 3 is located on the common wall of the external groove 4 and inner groovy 5, i.e., side opening is hidden in external groove, in drainage process, even if
Tissue is close to drainage head outer wall, and since external groove is more narrow, tissue is not likely to enter in narrow external groove, no
Side opening can be caused to block, moreover, inner groovy makes the inner wall out-of-flatness of drainage head, drainage head be squeezed to axle center, even if in drainage head
Main channel closing, inner groovy remains able to form drainage channel, it is ensured that drainage is smoothed out, and can effectively improve drainage effect
Rate reduces patient's pain.
