Abstract
The utility model discloses a hepatobiliary drainage tube, which comprises a tube body, wherein a conical head is arranged on the front end of the tube body, a drainage portion is arranged on the tube body which is arranged on the rear of the conical head, drainage holes are arranged on the peripheral side walls of the drainage portion, an expansion portion is arranged on the tube body which is arranged in the rear of the drainage portion, a support spring is arranged on the inner side wall close to the expansion portion, a ring-shaped air bag is arranged on the expansion portion close to the outer side wall, and the air bag is close to the outer side wall of the expansion portion of the tube body in a non-inflatable state. An air injection tube is arranged on the inner side wall of the hepatobiliary drainage tube, the front end of the air injection tube is communicated with the air bag, and the rear end of the air injection tube passes through the rear side wall of the tube body to be connected with an air pump, the rear end of the tube body is connected with a negative pressure liquid storage cavity, and the negative pressure liquid storage cavity is further provided with a liquid drain valve and a one-way vent valve. The air bag is arranged on the rear end of the drainage portion, the air bag expands when inflating, and can prevent the tube body from sliding out from the hepatobiliary. The drainage effect is improved in the negative pressure by arranging the negative pressure liquid storage cavity on the rear end of the tube body.
Description
Technical field
This utility model relates to a kind of medical apparatus, specifically a kind of liver and gall drainage tube
Background technology
At present, in treatment clinical course, liver and gall drain is one of modal treatment measure, general is all that the drainage tube that is provided with porous is placed in the bile duct of expansion, but because drainage tube front and back end diameter is identical, and tube wall is smooth, so be very easy to, existing a kind of bracing wire that is provided with in pipe, bracing wire one end out joins with drainage tube termination from drainage tube side opening, the bracing wire other end is outside pipe, after in drainage tube enters bile duct, utilize bracing wire by the drainage tube termination stretch bending entering in bile duct, although this drainage tube has solved the problem of deviating from, but because of the bad control of drainage tube tip bend direction, and can not effectively process the liquid draining, drainage effect is poor.
Utility model content
For above-mentioned problems of the prior art, this utility model aims to provide a kind of simple in structure, easy to use, can improve drain stability, again can be by the hepatobiliary drainage device of the fluid preservation draining.
For achieving the above object, this utility model is taked following technical scheme:
A kind of liver and gall drainage tube, comprise body, described body front end arranges conical head, described conical head rear is provided with body and is provided with drain portion, and described drain portion around sidewall is provided with conduction hole, and described drain portion rear body is provided with expanded support portion, described expanded support portion is close to medial wall and is provided with a support spring, described expanded support portion is close to lateral wall and is provided with an annular air-pocket, and described air bag, under non-inflated state, is close to body expanded support portion lateral wall.
Described drainage tube medial wall is provided with air injection pipe, and described air injection pipe front end communicates with air bag, and air injection pipe rear end passes body rear end sidewall and is connected with air pump.
The rear end of described body is connected with negative pressure liquid storage cylinder, on described negative pressure liquid storage cylinder, is also provided with tapping valve and one-way exhaust valve.By one-way exhaust valve, be connected with negative pressure equipment, be convenient to formation subnormal ambient in negative pressure liquid storage cylinder, thereby drain is more easily carried out.
Further, described air bag lateral wall is provided with anti-slip veins, thereby strengthens anticreep effect.
The beneficial effects of the utility model are: by air bag being set in drain portion rear end, during inflation, air bag expands, and can avoid body from slippage in liver and gall; By negative pressure liquid storage cylinder being set in body rear end, subnormal ambient has improved drainage effect.This utility model is simple in structure, easy to use, can improve drain stability, again can be by the fluid preservation draining.
Accompanying drawing explanation
This utility model internal structure schematic diagram when Fig. 1 is air bag unaerated
This utility model structural representation when Fig. 2 is airbag aeration
Labelling in figure: the 1-body 2-conical head 3-drain 4-of the portion expanded support 5-of portion spring 6-air bag 7-air injection pipe 8 air pump 9-one-way exhaust valve 10-tapping valve 11-conduction hole 12--negative pressure liquid storage cylinders
The specific embodiment
For the ease of understanding, below in conjunction with accompanying drawing, by embodiment, the technical solution of the utility model is further described in detail:
A kind of liver and gall drainage tube, comprise body 1, described body front end arranges conical head 2, described conical head 2 rears are provided with body and are provided with drain portion 3, and described drain portion 3 around sidewall is provided with conduction hole 11, and described drain portion 3 rear bodys are provided with expanded support portion 4, described expanded support portion 4 is close to medial wall and is provided with a support spring 5, described expanded support portion 4 is close to lateral wall and is provided with an annular air-pocket 6, and described air bag 6, under non-inflated state, is close to body expanded support portion lateral wall.
Described drainage tube 1 medial wall is provided with air injection pipe 7, and described air injection pipe 7 front ends communicate with air bag 6, and air injection pipe 7 rear ends pass body 1 rear end sidewall and are connected with air pump 8.
The rear end of described body 1 is connected with negative pressure liquid storage cylinder 12, is also provided with tapping valve 10 and one-way exhaust valve 9 on described negative pressure liquid storage cylinder 12.By one-way exhaust valve 9, be connected with negative pressure equipment, be convenient to the interior formation subnormal ambient of negative pressure liquid storage cylinder 12, thereby drain is more easily carried out.
During use, after drainage tube 1 enters in the cystic duct of expansion, by air pump 8 to the interior inflation of air bag 6, thereby expanding, air bag 6 can avoid body 1 from slippage in liver and gall, after drain completes, the gas in air bag 6 is discharged, drainage tube 1 just can take out smoothly from bile duct.
Above embodiment is only illustrating the technical solution of the utility model, and can not be interpreted as restriction of the present utility model, those of ordinary skill in the art can make various changes to it in the form and details, should be included in appended claims limited range.
