Description

A kind of conduit for knee joint irrigation and drainage

Technical field

The utility model is related to medical instruments fields, specifically a kind of conduit for knee joint irrigation and drainage.

Background technology

Drainage tube is clinically used conduit, is that the gas, digestive juice, notch that will be gathered between tissue or in body cavity ooze Go out liquid etc. to be excreted by conduit in time.The drainage tube structure for being conventionally used to knee is relatively simple, is the conduit of the same shape, leads to Often it is round or flat, circular hole is provided on Drainage Section, for draining.

In drainage, circular hole easily blocks conventional knee drainage tube, and often generation inadequate drainage, drainage be not complete, and body fluid is caused to store Product, in addition, it cannot meet the needs of drug injection, cleaning while drainage, is also easy to be lived by patient to generate infection Moving influences and is drawn out in vitro, to be difficult to ensure drainage effect.

Utility model content

The purpose of this utility model is just to provide a kind of conduit for knee joint irrigation and drainage, to solve existing knee joint The problem of easily being blocked with drainage tube, and drug injection, cleaning, drainage demand cannot be met simultaneously.

What the purpose of this utility model was realized in：A kind of conduit for knee joint irrigation and drainage, including connect successively Flushing pipe section, drainage cross pipeline section and the drainage pipe section of setting are connect, the drainage cross pipeline section is by internal cross Shim and outer pipe wall are constituted, and the tube chamber for draining cross pipeline section is separated to form four drainage troughs by the cross shim, The drainage notch of the entire drainage cross pipeline section of perforation is provided on each drainage trough corresponding part tube wall；The drainage cross The outer diameter of pipeline section is less than the flushing pipe section and drains the outer diameter of pipe section, the drainage cross pipeline section and the flushing pipe Section, the junction for draining pipe section are equipped with tapering transition section, close to tapering transition section in the flushing pipe section One end is equipped with flushing hole, and described flushing the another of pipe section is terminated with female Luer.

The width of the drainage notch is less than the cross-sectional arc length of the drainage trough corresponding part tube wall, and the drainage trough Mouth is located at the centre position of drainage trough corresponding part tube wall.

It is respectively provided with a flushing hole in the two opposite side surfaces for rinsing pipe section, described two flushing holes are along conduit Extending direction is staggered.

The flushing pipe section, drainage cross pipeline section, drainage pipe section and tapering transition section are an extrusion molding, respectively Junction transition is round and smooth between section, seamless.

The utility model is simple in structure, easy to use, of low cost.Draining cross pipeline section has four continuous drainages Slot is capable of continuous and effective and drain, and is not easy to plug.Furthermore it is possible to meet simultaneously drug injection, cleaning, drainage need It asks, the effective infection for reducing postoperative drainage.

The both ends for draining cross pipeline section have tapering transition, conduit can be effectively prevent to be drawn out body because of patient activity Outside.The utility model is realized using the method for disposable extrusion molding, does not have to bonding and junction intensity is big, be not easy to break, Transition is round and smooth between each pipeline section, will not be damaged to patient surface or uncomfortable.

Description of the drawings

Fig. 1 is the structural schematic diagram of the utility model.

Fig. 2 is the partial structurtes diagrammatic cross-section of the utility model, wherein I is the structure enlargement diagram of flushing hole, A- A is the cross-sectional view for draining cross pipeline section.

In figure：1, pipe section is rinsed, 2, drainage cross pipeline section, 3, drainage pipe section, 4, cross shim, 5, tube wall, 6, drainage trough, 7, drainage notch, 8, tapering transition section, 9, flushing hole, 10, female Luer.

Specific implementation mode

As illustrated in fig. 1 and 2, the utility model include the flushing pipe section 1 for being sequentially connected setting, drainage cross pipeline section 2 with And drainage pipe section 3, drainage cross pipeline section 2 are made of internal cruciform shim 4 and outer pipe wall 5, cross shim 4 will The tube chamber of drainage cross pipeline section 3 is separated to form four drainage troughs 6, and it is whole that perforation is provided on 6 corresponding part tube wall 5 of each drainage trough The drainage notch 7 of a drainage cross pipeline section 3, the length for draining notch 7 is identical as the drainage length of cross pipeline section 3, drains notch 7 Width be less than 6 corresponding part tube wall 5 of the drainage trough cross-sectional arc length, and drain notch 7 be located at 6 corresponding part of drainage trough The centre position of tube wall 5.

The outer diameter for draining cross pipeline section 2 is less than the outer diameter of the flushing pipe section 1 and drainage pipe section 3, drains cross tee Section 2 and the junction of the flushing pipe section 1, drainage pipe section 3 are equipped with tapering transition section 8, and tapering transition section 8 can be effective Conduit is drawn out in vitro because of patient activity.It is each in the two opposite side surfaces of 8 one end of tapering transition section rinsing pipe section 1 If there are one flushing hole 9, two flushing holes 9 are staggered along conduit extending direction, facilitate irrigation and disinfection liquid, infusion of medicine trouble Place rinses the another of pipe section 1 and is terminated with female Luer 10.

The utility model uses the disposable extrusion molding of medical silica-gel, rinses pipe section 1, drainage cross pipeline section 2, drainage circle Junction transition between pipeline section 3 and tapering transition section 8 is round and smooth, seamless, and intensity is very much not easily broken.

In knee operation, when needing to drain, 3 port of drainage pipe section is connect into biopsy needle guide, passes through and needs The affected part region of drainage simultaneously pulls out, until drainage cross pipeline section 2 and the flushing hole 9 rinsed in pipe section 1 are embedded to affected part. The female Luer 10 for rinsing pipe section 1 connects flusher or delivery device, for injecting cleaning disinfection liquid or drug, satisfaction pair to affected part Affected part carries out cleaning and sterilizing or injects the demand of drug.Drainage pipe section 3 connects vacuum suction source or drainage bag, can continue to carry out Drainage.Drainage cross pipeline section 2 is four drainage troughs 6 of segmentation, more convenient to use, ensure that drainage fully and is not easy to plug, It can be drained while irrigation and disinfection when use, can effectively avoid, reduce infection.
