Background technology
When small intestinal or large bowel obstruction, block near-end intestinal tube and obviously expand, a large amount of intestinal contentses stockpile in intestinal tube, need to be on operating-table, it is emptying when operation, and excision pathological changes is carried out coincideing of intestinal tube.In at present conventional art, the mode of depressing intestinal canal has the depressing intestinal canal that uses suction pump insertion expansion, and the method very easily causes intraperitoneal and operating room severe contamination, and consuming time very long, complicated operation; Another method is for being used decompressor to reduce pressure.The structure of decompressor generally comprises two ends and has the hollow pipe of opening, and one of them opening of described hollow pipe is for being combined with intestinal, and to receive the ejection of intestinal, ejection, through hollow pipe, enters by another opening receiving in dirty bag of being connected.But existing decompressor design is too simple, operating difficulties, safety is low, when use, blocking intestinal tube is combined comparatively difficult with hollow pipe, easily cause departing from, cause leakage, pollute, and lack the simultaneously function of enteroclysis, be badly in need of having more using safety, decompressor simple to operate.
In Chinese patent CN03262061.6 and CN201210006141.5, all disclose a kind of decompression gathering-device, adopted band to be fixed on hollow pipe intestinal tube.US Patent No. 5443445 discloses another kind of decompression gathering-device, offers dirt-collecting passage and clear water irrigation channel on the device tube wall extending in intestinal tube, can play the function that coloclysis cleans.But these above decompression gathering-devices are in the situation that running into intestinal tube internal diameter and differing, will cause producing that the easy-to-use greatly and not band of intestinal tube internal diameter is tightened or intestinal tube internal diameter is little and can not be to the risk that stretches into decompression gathering-device in it.
Utility model content
The purpose of this utility model is to provide a kind of adjustable decompression gathering-device simple in structure, safe, run in the situation that intestinal tube internal diameter differs, also can not cause producing that the easy-to-use greatly and not band of intestinal tube internal diameter is tightened or intestinal tube internal diameter is little and can not be to the risk that stretches into decompression gathering-device in it.
The purpose of this utility model, will be achieved by the following technical programs:
A kind of decompression gathering-device, comprise: mutual co-axially fixed inner and outer tubes, described inner tube comprises first passage, described outer tube comprises second channel, described first passage and second channel are interconnected, the rear end of described inner tube is arranged with one and receives dirty bag, described outer tube is arranged on the front end of inner tube, described outer tube be opening foremost, the periphery of described outer tube can be sheathed for tightening the band of tissue, described outer tube comprises first paragraph and second segment, described first paragraph is socketed in described inner tube, described second segment is located at the front end of first paragraph, the external diameter of described second segment is less than the external diameter of described first paragraph.
Preferably, the periphery of described first paragraph is provided with the projection coordinating with band; The periphery of described second segment is provided with the projection coordinating with band.
Preferably, the periphery of described inner tube is provided with and receives the dirty bag of projection being connected.
Preferably, described inner tube comprises a rinse part, described rinse part comprises inlet segment and purge zone, the inside conducting of described inlet segment and purge zone, described inlet segment runs through and is inserted in described inner tube, described purge zone is located in described inner and outer tubes, the back-end closure of described purge zone, and front end is opening the front end that stretches out in described outer tube.
Preferably, described inlet segment is mutually vertical with purge zone.
Preferably, described purge zone and outer coaxial tube.
Preferably, described inlet segment overcoat has a funnel.
The beneficial effects of the utility model are mainly reflected in: take two sections of diameters different for stretching into the outer tube part of intestinal tube, can effectively reduce and produce because the easy-to-use greatly and not band of intestinal tube internal diameter is tightened or can not be to the risk that stretches into decompression gathering-device in it because intestinal tube internal diameter is little.
Brief description of the drawings

Fig. 2 is the exploded perspective view of the preferred embodiment of this utility model decompression gathering-device.
Detailed description of the invention
As depicted in figs. 1 and 2, the decompression gathering-device of this utility model preferred embodiment, comprise: mutual co-axially fixed inner tube 1 and outer tube 2, described inner tube 1 comprises first passage 11, described outer tube 2 comprises second channel 21, described first passage 11 and second channel 21 are interconnected, and the rear end of described inner tube 1 is arranged with one and receives dirty bag 3, and the periphery of described inner tube 1 is provided with and receives dirty bag 3 projections that are connected 12.
Described outer tube 2 is arranged on the front end of inner tube 1, described outer tube 2 be opening 22 foremost, the periphery of described outer tube 2 can be sheathed for tightening the band 4 of tissue, described outer tube comprises first paragraph 23 and second segment 24, described first paragraph 23 is socketed in described inner tube 1, described second segment 24 is located at the front end of first paragraph 23, and the external diameter of described second segment 24 is less than the external diameter of described first paragraph 23.The periphery of described first paragraph 23 is provided with the projection 25 coordinating with band 4; The periphery of described second segment 24 is provided with the projection 25 coordinating with band 4.
In operation process, outer tube 2 is extend in intestinal tube tissue, described in the process of then defecating second channel 21, first passage 11 are collected in, receive in dirty bag.Because the first paragraph 23 of outer tube 2 is different with the external diameter of second segment 24, therefore can determine which section to tighten interior tubing by according to the internal diameter of intestinal tube.For example, when running into sufferer for child, its intestinal tube internal diameter is little, adopt second segment 24 to stretch in intestinal tube tissue to perform the operation, and band 4 is also only tightened in second segment 24 peripheries.Vice versa.
