Description

Postoperative drainage device for colorectal patient

Technical Field

The utility model relates to the technical field of gastrointestinal medical instruments, in particular to a postoperative drainage device for a colorectal patient.

Background

After the surgical resection of the tumor of the colon or rectum is completed, when the end of the colon or rectum left after the surgical resection is anastomosed with the other end of the remaining rectum, a drainage tube is usually placed in the colon or rectum for drainage, and the existing drainage tube is a straight tube with one end in the colon or rectum and the other end extending out of the anus during use.

However, a cavity exists between the front end of the existing drainage tube and the inner wall of the colon or rectum, and secretion discharged from the colon or rectum enters the cavity between the drainage tube and the inner wall of the rectum and is discharged from the anus, so that the wound of a patient is polluted, and the wound of the patient is not recovered.

SUMMERY OF THE UTILITY MODEL

Aiming at the situation, in order to overcome the defects of the prior art, the utility model aims to provide the drainage device for the colorectal patient after the operation, and effectively solves the problem that the wound of the patient is easily infected by the existing drainage device.

The technical scheme includes that the pipe comprises an upper axial pipe body and a lower axial pipe body, a plurality of inverted L-shaped expansion plates are hinged to the upper end of the pipe body and are uniformly distributed in the circumferential direction of the pipe body, a connecting device is arranged between two adjacent expansion plates and comprises two arc-shaped expansion rods which are hinged to each other, the free ends of the expansion rods are hinged to the expansion plates on the corresponding sides of the expansion rods, the lower ends of the two adjacent expansion plates are connected through inward shielding blocks of arc openings, blocking cloth is arranged between the shielding blocks and the two expansion rods on the same side, and the free ends of the blocking cloth are fixedly connected with the expansion plates.

The utility model has smart structure and convenient operation, and medical staff can shield the operation wound of a patient by pulling the sliding ring downwards, thereby preventing intestinal secretion from polluting the wound.

Detailed Description

The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.

By figure 1 to 5 and give, axial body 1 about including, body 1 upper end is articulated to have a plurality of expansion plates 2 along its circumferencial direction equipartition and the shape of falling L, be equipped with connecting device between two adjacent expansion plates 2, connecting device includes two articulated connection and curved expansion rod 3, expansion rod 3 free end is articulated to be connected rather than the expansion plate 2 that corresponds the side, two adjacent expansion plate 2 lower extremes are connected through the inside piece 4 that shelters from of nock, shelter from piece 4 and be equipped with between two expansion rods 3 with one side and keep off cloth 5, keep off cloth 5 free end and expansion plate 2 fixed connection.

In order to facilitate the swinging of the expansion plate 2, the lower end of the pipe body 1 is coaxially and slidably connected with a sliding ring 6, the sliding ring 6 is provided with a plurality of pull ropes 7 which are in one-to-one correspondence with the expansion plate 2, and the free ends of the pull ropes 7 are fixedly connected with the expansion plate 2.

In order to support the expansion plate 2 for limitation, the pipe body 1 is provided with a plurality of clamping grooves 8 corresponding to the expansion plate 2 one by one, a supporting rod 9 which is in an L shape and is arranged in the clamping grooves 8 in the vertical direction, and the outer end of the expansion plate 2 can be contacted with the upper end of the supporting rod 9.

In order to facilitate the reposition of the expansion board 2, the expansion board 2 is connected with the support rod 9 on the corresponding side thereof via a spring piece 10.

In order to make the expansion plate 2 swing better, the support rod 9 is provided with a limit groove 11 with the same shape, and the pull rope 7 is positioned in the limit groove 11 on the corresponding side.

In order to limit the sliding ring 6, the lower end of the tube body 1 is coaxially provided with an elastic ring 12, and the sliding ring 6 can be positioned below the elastic ring 12.

When the utility model is used, medical staff place the tube body 1 in the colon of a patient, the wound of the patient is positioned below the supporting rod 9, and the lower end of the tube body 1 is positioned outside the anus of the patient;

after the tube body 1 is placed, a medical worker holds the tube body 1 by hands, slides the sliding ring 6 downwards at the same time, moves the sliding ring 6 downwards, drives the expansion plate 2 to swing outwards through the pull rope 7 by the sliding ring 6, the spring piece 10 is compressed under the stress, drives the expansion rods 3 on two sides to swing outwards while the expansion plate 2 swings outwards, and drives the blocking cloth 5 on the expansion rods 3 to open;

when the outer end of the expansion plate 2 is contacted with the upper end of the supporting rod 9, the expansion plate 2 cannot swing outwards under the action of the supporting rod 9, the upper end of the expansion plate 2 is completely contacted with the colon wall of the patient, and when the expansion plate 2 cannot swing outwards, the blocking cloth 5 is in an opening state, and the wound of the colon of the patient is blocked;

in the process that the expansion plate 2 is expanded outwards, the sliding ring 6 gradually moves downwards, the elastic ring 12 is gradually contacted with the sliding ring 6, the elastic ring 12 is deformed under the action of the sliding ring 6, when the expansion plate 2 cannot move downwards, the upper end of the sliding ring 6 is contacted with the lower end of the elastic ring 12, the sliding ring 6 is limited at the moment, medical staff loosen the sliding ring 6, the sliding ring 6 cannot move upwards under the action of the elastic ring 12, and the expansion plate 2 is always in an expansion state;

after the patient healed up, medical staff upwards slides sliding ring 6, makes elastic ring 12 take place deformation, removes spacing to expansion plate 2, expansion plate 2 inwardly swinging under the effect of

spring leaf

10, and 3 pin joints of two adjacent expansion rods inwardly swinging under the effect of fender cloth 5, the sheltering from of fender cloth 5 cancellation to patient's colon wound department, medical staff takes out body 1 from patient anus department.

The tube body 1 of the utility model can be made of flexible material, which is convenient for placing the tube body 1 in the colon of a patient.

The medical device has the advantages of simple structure, convenient operation, novel concept and strong practicability, medical staff can open the expansion plates and contact with the inner wall of the intestinal tract of a patient only by pulling the sliding ring downwards, and meanwhile, the blocking cloth is opened to shield gaps between the expansion plates, so that secretion is prevented from contacting the wound of the patient.
