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, and clot, tissue etc. is brought to be 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 with pre-washing function,
The technical solution adopted is that：The circle small pipeline along length direction is provided in tube wall, small pipeline forms capillary phenomenon, generates one
Fixed negative pressure can not only drain away a small amount of thin body fluid, and small pipeline close-packed arrays also play drainage tube wall
To supporting role, effectively prevent drainage tube and be crushed and drainage tube discounting, but due to draining tube extrusion molding, tube wall is relatively thin,
The difficulty of processing is increased, 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 intraperitoneal drainage for having and rinsing with drainage function
Pipe.
Technical solution is used by the utility model solves its technical problem：
A kind of peritoneal cavity drainage tube with pre-washing function, including conduit, flush pipe and the drainage head for being connected to catheter proximal end,
The front end of the drainage head is cambered surface, front aperture is provided in the front end of the drainage head, side wall is provided with side opening, the conduit
Side wall be provided with insertion hole, the front end of the flush pipe be inserted into the insertion hole and extend to the drainage head it is interior before
End, the outer wall of the flush pipe are tightly connected with the insertion hole.
If the outer wall of the drainage head is provided with the external groove that arterial highway arranges along its length, the side opening is located at described outer
In 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.
Sealing valve is separately installed in the conduit and flush pipe.
The beneficial effects of the utility model are：The utility model is provided with insertion hole in the side wall of conduit, and flush pipe passes through
Insertion hole extends to the Inner Front End of drainage head, and when being drained, flush pipe is closed, and closed catheter when being rinsed drainage does not need to
Inserting two pipes can just complete to rinse and drain, and improve drainage efficiency, reduce the pain of patient.
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 radial cross-section of the utility model；
Fig. 3 is the axial sectional view of the utility model.
Specific embodiment
Referring to figs. 1 to Fig. 3, a kind of peritoneal cavity drainage tube with pre-washing function is led including conduit 6, flush pipe 7 and being connected to
The drainage head 1 of 6 front end of pipe, by medical silica gel extrusion molding, conduit 6 and 1 later stage of drainage head are close for conduit 6, flush pipe 7, drainage head 1
Envelope connection.
The front end of the drainage head 1 is cambered surface, the front end of the drainage head 1 is provided with front aperture 2, side wall is provided with side
Hole 3, the side wall of the conduit 6 are provided with insertion hole 8, and the front end of the flush pipe 7 is inserted into the insertion hole 8 and extends to institute
State the Inner Front End of drainage head 1（I.e. the front end of flush pipe 7 is located at 1 inside of drainage head close to the position of front aperture）, the flush pipe 7
Outer wall be tightly connected with the insertion hole 8, sealing valve is separately installed in the conduit 6 and flush pipe 7, when being drained
Flush pipe is closed, closed catheter when being rinsed drainage, and not needing to slotting two pipes can just complete to rinse and drain, and improve and draw
Flow efficiency.
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 institute
It states in external groove 4, if the inner wall of the drainage head 1 is provided with the inner groovy 5 that arterial highway arranges along its length.The external groove 4
Section for narrow 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 radial section, outside
Groove 4, inner groovy 5 are equiangularly arranged as dot using the center of circle of drainage head 1）, the external groove 4 and inner groovy 5 be alternatively arranged, institute
Side opening 3 to be stated to be 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, since external groove is more narrow, tissue is not likely to enter narrow external groove
It is interior, side opening will not 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 drainage
Main channel closing in head, inner groovy remain able to form drainage channel, it is ensured that drainage is smoothed out, and can effectively improve drainage
Efficiency reduces patient's pain.
