Abstract

The utility model relates to an anti-blocking drainage tube, which is characterized in that the interior of the drainage tube is additionally provided with a stasis scraping device and a thin wall hose of which the interior is provided with a spring. When the drainage tube is blocked by a stasis block, the thin wall hose with the spring is repetitively pushed and pressed rightward. The stasis scraping device positioned at the tail of the drainage tube can continuously squeeze the stasis block to crush and discharge the crushed stasis block from the drainage tube. Thereby, no blocking drainage is realized.

Description

The anti-blocking drainage device

This utility model relates to a kind of medical drainage apparatus.

Behind surgical operation, often need in human body, insert drainage tube, to discharge intravital fluid foreign body, but existing drainage tube to osteomyelitis, suppurative arthritis and on phenomenon courageous and upright, that the abscess thing stops up drainage tube often takes place during drain such as urethra postoperative irrigation drain, cause drainage effect poor, even the drain failure.For this reason, CN2183785y discloses a kind of medical drainage dredge, and this drain dredge stirs axle by the driven by motor suction, stirring a front portion has impeller or screw thread, and courageous and upright, dense property thing can be blended and pump out thus, but its complex structure, involve great expense, be difficult to extensive popularization; CN2131532y discloses a kind of accumulation energy type automatic negative-pressure drainage device again, be characterized on drainage tube, being provided with the compressible bottle of band elasticity fold plane, make the drainage tube internal clearance produce negative pressure-pumping hemorrhagic, purulence thing by pushing bottle repeatedly, its shortcoming is that courage and uprightness, the purulence thing to intravital bulk still is difficult to discharge.

The purpose of this utility model be design a kind of simple in structure, cost is low and practical anti-blocking drainage device.

This utility model is achieved in that

A kind of anti-blocking drainage device, relate to drain pipe, afterbody can be inserted intravital drainage tube, it is characterized in that having pipe joint one end to be communicated with drain pipe, the other end is with thin walled hose; spring is housed in the thin walled hose; the thin walled hose other end is placed on the drainage tube, and is provided with locked instrument between pipe joint and drainage tube head, is provided with at the drainage tube afterbody and scrapes stasis of blood device.

Further scheme is, described locked instrument is made of with the locking part that is fixed in the drainage tube head the snap close that is articulated on the pipe joint.

Further scheme is, the described stasis of blood device of scraping is fixed in the pipe joint inwall by an end, and the connecting rod that the other end is fixed with scraping blade constitutes, and the scraping blade diameter is less than the drainage tube internal diameter.

Further scheme is again, and the drainage tube afterbody is a tooth mouth shape, and the described stasis of blood device of scraping relates to connecting rod, and connecting rod one end is fixed in the pipe joint inwall, and the other end is fixed on the tooth mouth sheet of drainage tube afterbody.

In this utility model, described locked instrument can also be by being wound in the adhesive plaster replacement between pipe joint and the drainage tube head or being similar to belt buckle snap-fastener etc., can be threaded or sawtooth on the described connecting rod, described scraping blade can be the film of disc, corolla shape or other shape, and described drainage tube afterbody can be shapes such as tack, plagiocephaly, tooth mouth, elbow.Described hinged snap close can be that an end is fixed in the ribbon on the pipe joint.

The utility model has the advantages that simple in structure, easy to operate, cost is low, it is effective to scrape the stasis of blood, is convenient to make disposable anti-blocking drainage device, and this design also meets the medical aseptic principle.

Fig. 1 is an assembling sketch map of the present utility model.

Fig. 2 is the sketch map that innerspring thin walled hose is in compressive state.

Fig. 3 is that the drainage tube afterbody is tooth mouth shape and scrapes the drainage tube afterbody sketch map that is provided with scraping blade in the stasis of blood device.

Fig. 4 is that the drainage tube afterbody is elbow-shaped and scrapes the drainage tube afterbody sketch map that is provided with scraping blade in the stasis of blood device.

Fig. 5 is that the drainage tube afterbody is that tooth mouth shape and connecting rod are fixed in a drainage tube afterbody sketch map on the tooth mouth sheet.

Below in conjunction with accompanying drawing this utility model is described further.

As Fig. 1 and Fig. 2, Fig. 1 medi-spring 4 is in relaxed state, and Fig. 2 medi-spring 4 is in compressive state.When courage and uprightness, the obstruction of purulence stasis of blood piece occurring, open locked instrument 6, being about to snap close 8 takes off from locking part 9, spring 4 just is returned to Fig. 1 state, push pipe joint 2 then repeatedly to the right, scrape stasis of blood device 7 just can be constantly stasis of blood piece in the body is squeezed broken, and by drainage tube 5 → thin walled hose 3 → pipe joint 2 → enter drain pipe 1 to discharge.When not meeting the obstruction of stasis of blood piece, locked instrument 6 lockings can be about to snap close 8 and be buckled on the locking part 9, can be flowed out naturally by drain, this moment, spring 4 was in compressive state, thin walled hose 3 surface formation fold planes.

As Fig. 1, Fig. 3 and Fig. 4, the described stasis of blood device 7 of scraping relates to a connecting rod (finer wire) 10, connecting rod 10 1 ends are fixed in pipe joint 2 inwalls, the other end is positioned at inclined plane shape or tooth mouth shape or elbow shape drainage tube 5 afterbodys, and scraping blade 11 is equipped with in the end, and when spring 4 was in relaxed state, scraping blade 11 can be positioned at drainage tube 5 afterbodys, when spring 4 was in compressive state, scraping blade 11 was positioned at outside drainage tube 5 afterbodys.Push pipe joint 2 repeatedly to the right, connecting rod 10 just drives scraping blade 11 continuous move left and right, can squeeze broken stasis of blood piece, and realizing does not have the drain of obstruction.

As Fig. 1 and Fig. 5, the another kind of implementation of scraping stasis of blood device 7 is, connecting rod (finer wire) 10 1 ends still are fixed in pipe joint 2 inwalls, the other end is fixed on the tooth mouth sheet of drainage tube 5 afterbodys, when meeting stasis of blood piece, snap close 8 is taken off from locking part 9, push pipe joint 2 repeatedly to the right, connecting rod 10 just makes the continuous opening and closing of tooth mouth sheet, realizes squeezing the purpose of broken stasis of blood piece.

In actual production, but pipe joint 2, discharging tube 1, thin walled hose 3, drainage tube 4 integral molded plastics are made.
