Abstract

The utility model relates to a medical drainage apparatus for surgery, which is provided with an outer tube and an expanding strip on the basis of the existing circular tube and drainage hole. The outer tube is sheathed on the external of the circular tube, the expanding strip is positioned on the upper end of the circular tube, one end of the expanding strip is connected with the circular tube, the other end of the expanding strip is connected with the outer tube, and the circular tube and the outer tube are fixed by an inner and outer tube, thereby, the utility model has the advantages of reasonable-design structure, convenient and reliable operation, effective blocking prevention and good drainage effect, etc., and the medical drainage apparatus has the function of inner fixing and has no resistance when the medical drainage apparatus is pulled out.

Description

Sliding support formula blockage resisting drainage tube

This utility model relates to a kind of sliding support formula blockage resisting drainage tube, and it belongs to medical apparatus and instruments, mainly is applicable to the drain that abdominal cavity, enteric cavity, wound chamber etc. are located.

Drainage tube is surgery a kind of medical apparatus and instruments commonly used, drainage tube of the prior art is made up of pipe and additional a plurality of side openings, during use, the pipe that has side opening one place is in human body to be needed on the position of drain, and by side opening and pipe with transudate, urine, outside the lead bodies such as blood, but the drainage tube of this structure in use remains in following shortcoming: 1, structural design is reasonable inadequately, pipeline regular meeting is by blood clot during use, slough, casing slime, organize fragment, abdominal tissue such as pus tongue and omentum majus are stopped up and are influenced the unobstructed of drain, have to pull out drainage tube sometimes even because of stopping up fully; 2, can not play good internal fixation effect, as fixing not good slippage sometimes; 3, drainage effect is not good, and above-mentioned shortcoming has had a strong impact on therapeutic effect, has brought many unnecessary miseries to patient, has brought many unnecessary troubles to the doctor yet.

The purpose of this utility model is to overcome existing above-mentioned deficiency in the prior art, and can be not blocked when a kind of reasonable in design, drain are provided, sliding support formula blockage resisting drainage tube that drainage effect is good.

The purpose of proposition of the present utility model can be achieved through the following technical solutions: this sliding support formula blockage resisting drainage tube, comprise pipe and conduction hole, conduction hole is opened the upper end at pipe, its construction features is also to be provided with outer tube and to expand bar, outer tube sleeve is connected on outside the pipe, the bar that expands is positioned at the upper end of pipe, and the one head is connected with pipe, and the other end is connected with outer tube.

This utility model also is provided with the inner and outer pipes locking pin in the lower end of outer tube, to play the fixedly effect of pipe and outer tube.

This utility model compared with prior art has the following advantages and effect: 1. reasonable in design, because design has the bar of expanding,, can guarantee the unimpeded of drain during use so have the internal fixation effect, and effectively prevent the generation of clogging, drainage effect is good; 2. easy to use and reliable, make things convenient for doctor's operation and alleviated patient's misery; 3. the bar that expands not only has the internal fixation effect and non-resistance when extracting.

Description of drawings is as follows:

Fig. 1 expands the structural representation of bar when strutting for this utility model.

Fig. 2 expands the structural representation of bar after being straightened for this utility model.

Following this utility model will be described in further detail in conjunction with the accompanying drawings and by embodiment.

Referring to Fig. 1, Fig. 2, this utility model mainly is made up of pipe 1, outer tube 3, conduction hole 4 and the bar 5 that expands, and pipe 1 is socketed in the outer tube 3, it can slide in outer tube 3, and the two ends of pipe 1 are exposed to outside the outer tube 3, and conduction hole 4 is opened in the upper end of pipe 1, and are exposed to outside the outer tube 3; The bar 5 that expands is positioned at the upper end of pipe 1, and the one head can be connected with pipe 1, and the other end can be connected with outer tube 3, and the bar 5 that expands in the present embodiment has four, and other quantity also can certainly; For fixing pipe 1 and outer tube 3, also be provided with inner and outer pipes locking pin 2.

During use, this utility model is placed on the position that the patient needs drain, and with pipe 1 when the lower end slides into to a certain degree, the bar 5 that expands promptly struts the effect of playing support, make the drain of pipe 1 there unsettled, can do not blocked, play good drainage by blood clot, sphacelus and omentum majus etc.; When pipe 1 when slide in the upper end, the bar 5 that expands promptly is straightened and is close on the pipe 1, just do not have resistance so extract drainage tube, and along with what of the sliding distance of pipe 1, the bar 5 that expands can arbitrarily change size and shape, thereby play the effect that adapts to different drainage lumens, even be plugged at this conduction hole 4, repeatedly slip by pipe 1, expand the stretching repeatedly of bar 5, strut also and can push the tissue that is attached on the conduction hole 4 open, reassure the unimpeded of drainage tube 4, and pipe 1 and outer tube 3 are fixed by inner and outer pipes locking pin 2, when finishing to pull out drainage tube, drain can remove inner and outer pipes locking pin 2, pipe 1 is stretching, make and expand bar 5 and be close to pipe 1 and extract and get final product.

This utility model can be used medical plastic, and silicone rubber or rubber are made, and can make various specification, model as required to form complete series of products, as " intrathoracic drain ", " peritoneal cavity drainage tube ", " ileal conduit drainage tube " or the like.
