Description
Technical field
The utility model relates to medical appurtenance fields, and in particular to a kind of attachment device of catheter.
Background technique
In clinical position, often need to carry out irrigation of bladder to facilitate inspection or surgical procedure, usually there are many patient
Infusion apparatus is connected to catheter nozzle, but since catheter nozzle diameter is larger, and infusion apparatus diameter is small, so needing with curved
Pincers clamp catheter, and enclosure portion catheter nozzle, to achieve the purpose that inject liquid into bladder, but operation is number in this way
It is tired, also it is not easy to be completely closed and lead to perfusion failure, clinical position is very inconvenient.And it is connected in existing catheter with infusion apparatus
In device, using a kind of tapered connector, by the way that tapered connector to be inserted into the nozzle of catheter, then going out infusion apparatus
Liquid mouth and connector are connected far from the one end at tapered end, and then realize the connection of catheter and infusion apparatus, are reached and are injected liquid into
The purpose of bladder.
But it is attached using such device, after the completion of irrigation of bladder, needs to take out tapered connector, due to tapered
Connector is in step-like, and the height single order of the step is greater than single order, the nozzle of catheter after taking out tapered connector
It is stretched, the nozzle connection that will lead to connector and catheter if carrying out secondary irrigation of bladder again is unstable, has liquid
The case where body drain goes out.
Utility model content
The utility model is intended to provide a kind of attachment device of catheter, when solving multiple irrigation of bladder infusion apparatus with lead
Urinary catheter connection is unstable, there is the problem of liquid leakage.
In order to solve the above-mentioned technical problem, the utility model provides the following technical solutions: a kind of attachment device of catheter,
Including secondary connecting tube and main connecting tube, the main connecting tube includes left end and right end, and the left end of main connecting tube is communicated with cone-shaped tube,
The inside of the cone-shaped tube is straight tube-like, and columnar first fixture block of multiple triangles is equipped on the outer wall of cone-shaped tube, multiple described
First fixture block joins end to end stepped distribution；The pair connecting tube includes siphunculus, and one end of siphunculus is communicated with looped pipeline, looped pipeline set
It connects in siphunculus, the inner wall of the other end of siphunculus is equipped with the second fixture block of multiple right-angled trapezium shapes, multiple second fixture blocks
Join end to end stepped distribution.
Cone-shaped tube: being inserted into the nozzle of catheter by utility model works principle when use, will by the first fixture block
Cone-shaped tube is fixed in the nozzle of catheter, then perfusion tube is inserted into siphunculus, since perfusion tube is the rubber using elasticity
Material is made, so perfusion tube is become smaller by the extruding of the second fixture block when being inserted into siphunculus, since perfusion tube has elasticity, so
The corner angle of second fixture block can fall into the tube wall of perfusion tube and perfusion tube is fixed, and siphunculus is pinched after use, by logical
Pipe extracts looped pipeline from main connecting tube, while connector being stayed in the nozzle of catheter.
The utility model has the following beneficial effects: this programme passes through cone by the way that cone-shaped tube to be inserted into the nozzle of catheter
Type pipe realizes a fixation of insert port, then by the way that looped pipeline to be inserted into main connecting tube, and siphunculus is connect with main connecting tube,
Looped pipeline is extracted by siphunculus from main connecting tube after use, new looped pipeline is inserted into main company in secondary use
In adapter tube, realize the multiple connection of perfusion tube and catheter, will not leakage beneficial effect.
Further, supporting block there are two being fixedly connected on the outer wall of the siphunculus, two supporting blocks are with the central axis of siphunculus
In mirror symmetry, it is rotatably connected to cross bar in two supporting blocks vertically respectively, one end of cross bar is fixedly connected with buckle, horizontal
It is fixedly connected with spring between the other end and siphunculus of bar, the convex block fastened with buckle is equipped in the main connecting tube.Its mesh
, when looped pipeline is inserted into main connecting tube, keep siphunculus not easily to fall off by buckle and fixture block fastening, while logical needing to pull up
Cross bar is pressed when pipe, take out buckle can by siphunculus with fixture block disengaging.
Further, the buckle is equipped with anti-skid chequer.The case where being had skidded when the purpose is to prevent from pressing buckle.
Further, it is cased with sealing ring on the looped pipeline, and sealing ring is fixedly connected with siphunculus.It is intended that preventing liquid
It is flowed out from gap between siphunculus and main connecting tube.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of catheter of the utility model.
Specific embodiment
It is further described below by specific embodiment:
Appended drawing reference in Figure of description includes: the first fixture block 1, main connecting tube 2, buckle 3, convex block 4, looped pipeline 5, cross bar
6, supporting block 7, spring 8, the second fixture block 9, siphunculus 10, sealing ring 11, cone-shaped tube 12.
Embodiment is substantially as shown in Fig. 1:
A kind of attachment device of catheter, including secondary connecting tube and main connecting tube 2, main connecting tube 2 include left end and right end,
The left end of main connecting tube 2 is communicated with cone-shaped tube 12, and the inside of cone-shaped tube 12 is straight tube-like, is equipped on the outer wall of cone-shaped tube 12 more
A columnar first fixture block 1 of triangle, multiple first fixture blocks 1 join end to end stepped distribution；Secondary connecting tube includes siphunculus 10, is led to
One end of pipe 10 is communicated with looped pipeline 5, and looped pipeline 5 is socketed in siphunculus 10, and sealing ring 11, the other end of siphunculus 10 are cased on looped pipeline 5
Inner wall be equipped with the second fixture block 9 of multiple right-angled trapezium shapes, multiple second fixture blocks 9 join end to end stepped distribution, siphunculus
10 one end for being connected with looped pipeline 5 are fixedly connected there are two supporting block 7, and two supporting blocks 7 are in mirror image pair with the central axis of siphunculus 10
Claim, be rotatably connected to cross bar 6 in two supporting blocks 7 vertically respectively, one end of cross bar 6 is fixedly connected with buckle 3, and buckle 3 is located at
By siphunculus 10, cross bar 6 is equipped with anti-skid chequer, and spring 8, main connecting tube 2 are fixedly connected between the other end and siphunculus 10 of cross bar 6
It is equipped with the convex block 4 fastened with buckle 3 outside.
Specific implementation process is as follows:
Cone-shaped tube 12 is inserted into the nozzle of catheter when use, then perfusion tube is inserted into siphunculus 10, due to defeated
Liquid pipe is made of the rubber material for using elasticity, so perfusion tube is become smaller by the extruding of the second fixture block 9 when being inserted into siphunculus 10,
Since perfusion tube has elasticity, so the corner angle of the second fixture block 9 can fall into the tube wall of perfusion tube and perfusion tube is fixed, make
Siphunculus 10 is pinched after, is extracted looped pipeline 5 from main connecting tube 2 by siphunculus 10, while cone-shaped tube 12 is stayed in into urethral catheterization
In the nozzle of pipe.
