TECHNICAL FIELD
[0001] The utility model relates to the field of medical apparatus and instruments, especially to a prevent sucking wall drainage device. BACKGROUND
[0002] Rectal cancer is a malignant tumor occurring between the dentate line and the rectosigmoid junction, and the occurrence of the disease is usually related to improper diet, heredity and other factors. The drainage tube after rectal cancer surgery usually refers to the abdominal drainage tube, which is generally removed 5-7 days after surgery when the amount of drainage fluid decreases and the properties of the drainage fluid are normal.
[0003] It should be noted that during the abdominal drainage process, the drainage tube needs to be inserted into the abdominal cavity and as close as possible to the location of the removed rectum. When the removed rectum is located lower, there are multiple tissues in the abdominal cavity, and after the rectum is removed, there may be narrow cavities (channels) between the abdominal cavity and the rectum and between the rectum and other tissues. After the drainage tube is inserted into the abdominal cavity, it may be inserted into such narrow cavities, causing the abdominal cavity tissues, abdominal cavity side wall, or rectal side wall to adhere to the drainage port of the drainage tube under the action of negative pressure suction during the drainage process, resulting in blockage of the drainage port and stopping of the drainage. At this time, medical staff need to pull and adjust the position of the drainage tube in time to ensure continuous drainage. However, due to the small size of the cavity, after the abdominal fluid in the cavity is drained, the drainage tube may be blocked again by the abdominal cavity tissues, abdominal cavity side wall, or rectal side wall due to the negative pressure effect, requiring medical staff to pay attention to the drainage situation and frequently adjust the position of the drainage tube during the drainage process, which is complicated to operate.
[0004] In addition, in the existing clinical practice, medical staff fix the position of the drainage tube outside the surgical incision using adhesive tape or gauze. When adjusting the insertion depth of the drainage tube back and forth, the adhesive tape needs to be pulled back and forth, which may cause damage to the patient's skin.
[0005] Therefore, how to design a prevent sucking wall drainage device that can solve the above technical problems is a technical problem to be solved. UTILITY MODEL CONTENTS

[0026] The present application will be further described in detail below in combination with the drawings and specific embodiments:
[0027] Referring to Figures 1-7 , the scheme includes a drainage tube assembly 1 and a limiting assembly 2 cooperating with the drainage tube assembly 1 for limiting the relative use position of the drainage tube assembly 1;
[0028] The drainage tube assembly 1 comprises a first drainage tube 11, an anti-suction wall drainage tube 12 communicated at one end of the first drainage tube 11, and a plurality of anti-suction baffle groups 131 arranged equidistantly along the circumference of the anti-suction wall drainage tube 12; each of the plurality of anti-suction baffle groups 131 comprises a plurality of arc-shaped anti-suction baffles 131 arranged equidistantly along the length direction of the anti-suction wall drainage tube 12; the outer side wall of the anti-suction wall drainage tube 12 is provided with a plurality of drainage hole groups 121 equidistantly along the circumference thereof, and each of the plurality of drainage hole groups 121 comprises a plurality of drainage large holes 1211 arranged equidistantly along the length direction of the anti-suction wall drainage tube 12; each of the plurality of arc-shaped anti-suction baffles 131 is arranged above one of the plurality of drainage large holes 1211; as shown in Figure 3 the cross section of each of the plurality of arc-shaped anti-suction baffle groups 131 arranged along the circumference of the anti-suction wall drainage tube 12 is substantially circular, facilitating the insertion of the anti-suction wall drainage tube 12.
[0029] The limiting assembly 2 comprises a sticking base plate 21 and a limiting tube 22 detachably connected with the sticking base plate 21; the limiting tube 22 has a larger diameter at the bottom than at the top; the sticking base plate 21 is provided with an opening 211 at the center position of the circle, which is matched in size with the first drainage tube 11 to facilitate the passing of the first drainage tube 11; a plurality of elastic connecting flanges 212 are vertically arranged on the sticking base plate 21 and form a circle matched with the limiting tube 22, and the opening 211 is arranged at the center of the plurality of elastic connecting flanges 212; the outer side wall of each of the plurality of elastic connecting flanges 212 is provided with an external thread 2121, and the inner side wall of the bottom of the limiting tube 22 is provided with an internal thread 221 matched with the external thread 2121; the limiting tube 22 is threadedly connected with the plurality of elastic connecting flanges 212.
[0030] The number of the plurality of elastic connecting flanges 212 is four, which is a preferred embodiment of the present application, but is not limited thereto, and different numbers of elastic connecting flanges 212 can also be used in other embodiments.
[0031] The inner side wall of each of the plurality of elastic connecting flanges 212 is fixedly provided with a plurality of anti-skid stripes 2122 along the height direction thereof, further enhancing the friction between the inner side wall of the elastic connecting flange 212 and the outer side wall of the drainage tube, so as to limit the drainage tube.
[0032] The lower surface of the sticking base plate 21 is fixedly provided with a sticking layer 213 matched in shape and size with the sticking base plate 21, and the lower surface of the sticking layer 213 is pasted with a protective paper 214 matched in shape and size with the sticking layer 213, facilitating the pasting of the sticking base plate 21 to the skin of the patient.
[0033] In order to increase the drainage efficiency, a plurality of drainage holes 1311 are formed in the arc-shaped anti-suction baffle 131.
[0034] The working principle is roughly as follows:
[0035] In use, the medical staff first extends the end of the anti-suction wall drainage tube 12 from the surgical opening into the patient's body, so that the end of the anti-suction wall drainage tube 12 is close to the drainage position, and the abdominal cavity of the patient is drained. When draining, the narrow abdominal cavity inner wall or rectal lateral wall or other tissues in the abdominal cavity are tightly attached to the arc-shaped anti-suction baffle 131 on the outer side of the anti-suction wall drainage tube 12 under the action of negative pressure suction, so as to avoid the abdominal cavity inner wall or rectal lateral wall or other tissues in the abdominal cavity blocking the drainage holes 1211 on the anti-suction wall drainage tube 12. Since there is always a gap between the arc-shaped anti-suction baffle 131 and the outer wall of the anti-suction wall drainage tube 12, the drainage holes 1211 are prevented from being blocked, the negative pressure drainage effect is prevented from being affected, and continuous drainage is achieved.
[0036] After determining that the drainage is performed, the first drainage tube 11 is passed through the opening 211 of the adhesive base 21, and the adhesive base 21 is adhered to the skin position outside the surgical opening of the patient through the adhesive layer 213. At this time, the limiting tube 22 is threadedly connected between the elastic connecting flange 212 which is enclosed into a circular shape, as shown in Figure 7 Since the diameter of the bottom of the limiting tube 22 is smaller than the diameter of the top, the limiting tube 22 is in the shape of a circular truncated cone. When the limiting tube 22 is threadedly connected with the elastic connecting flange 212, the elastic connecting flange 212 is gathered and tightly attached to the first drainage tube 11, thereby limiting the movement of the first drainage tube 11. If it is necessary to change the use position of the first drainage tube 11, the limiting tube 22 is reversely rotated in the same way, the connection between the limiting tube 22 and the elastic connecting flange 212 is released, and the use position of the first drainage tube 11 can be changed.
[0037] The above merely describes the specific implementation of the present application, and does not limit the patent scope of the present application. Any equivalent structural transformation or direct or indirect application in other related technical fields based on the content of the present application is also included in the patent protection scope of the present application.
