Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to a perianal drainage device. Background Art

[0002] Anorectal abscess is a common perianal infectious disease. Once diagnosed, surgical drainage is required immediately to quickly control the infection, relieve symptoms, and prevent further spread of the infection and affect anal function. The clinical treatment of anorectal abscess usually involves using a drainage tube to puncture the abscess wall and drain the pus inside.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0021] Example 1: Figure 1 The perianal drainage device shown comprises a drainage tube body 1, one end of the drainage tube body 1 is a drainage end 101, and the other end is a connecting end 102;

[0022] The connecting end 102 is provided with a first connecting port 103, the first connecting port 103 is connected to a drainage bottle, and the drainage bottle is connected to a negative pressure suction device; the drainage end 101 is provided with a drainage port 104, the drainage port 104 is connected to the drainage tube body 1; through the negative pressure suction device, the buffered pus enters the drainage bottle through the drainage port 104, the drainage tube body 1, and the first connecting port 103, so as to achieve drainage of the pus in the affected area;

[0023] The drainage tube body 1 is provided with a groove 2, the groove 2 is close to the drainage end 101, the groove 2 is arranged along the circumference of the drainage tube body 1, and the groove 2 protrudes from the outer wall of the drainage tube body 1 toward the center line of the drainage tube body 1; the arrangement of the groove 2 makes the outer wall of the drainage tube body uneven, thereby preventing the drainage tube body from falling out due to the smooth outer wall of the drainage tube body;

[0024] The drainage tube body 1 is also provided with an airbag 4, which is movably arranged on the outer wall of the drainage tube body 1; and the airbag 4 is located at the lower part of the groove 2; the airbag 4 is connected to one end of the first inflation tube 3, and the other end of the first inflation tube 3 is connected to the air source; the filling of the airbag 4 is achieved by inflating air into the airbag 4.

[0025] When the perianal drainage device of the present invention is used, the drainage end 101 of the drainage tube body 1 is extended into the abscess of the patient. When the drainage end 101 is inserted into the abscess, since the groove 2 on the drainage tube body 1 is arranged close to the drainage end, the groove 2 also enters the abscess. At this time, the outer wall of the drainage tube body entering the abscess is uneven, which is conducive to positioning the drainage tube inserted into the abscess area and avoiding the drainage tube body from falling out. At this time, the airbag 4 can be inflated through the first inflation tube 3 to fill the airbag 4, which is conducive to the airbag 4 limiting the length of the drainage tube body extending into the abscess area. The length of the drainage tube body 1 extending into the abscess can be adjusted according to the size of the abscess. Specifically, after the drainage end of the drainage tube body 1 is extended into the abscess area, the position of the airbag on the drainage tube body 1 can be adjusted by external force according to the length of the drainage tube body 1 entering, thereby achieving the limit fixation of the drainage tube body 1, avoiding the situation where the drainage tube body 1 extends too long into the abscess due to misoperation, and ensuring the drainage efficiency of the abscess area; at this time, the negative pressure drainage device is started, and the pus enters the drainage bottle through the drainage port 104, the drainage tube body 1, and the first connecting port 103, so as to achieve the drainage of the pus in the affected area.

[0026] As a preferred embodiment, the airbag 4 in the present application is made of silicone material. The soft silicone material avoids causing harm to the patient, and the airbag 4 moves up and down along the outer wall of the drainage tube body 1 under the action of external force, so as to facilitate adjusting the position of the airbag 4 on the drainage tube body 1 according to the condition of the patient's abscess, thereby improving the adaptability of the drainage device and avoiding harm to the patient caused by the drainage tube body being inserted into the abscess too long due to misoperation.

[0027] As a preferred embodiment, a connection hole 105 is further provided on the drainage tube body 1 in the present application near the connection end 102, and the connection hole 105 can be connected to a flushing mechanism to facilitate flushing of the abscess area after pus drainage.

[0028] A plurality of drainage holes 106 are also provided on the drainage tube body 1 between the groove 2 and the drainage end 101 in the present application, and the plurality of drainage holes 106 are arranged along the circumference of the outer wall of the drainage tube body 1; the arrangement of the plurality of drainage holes 106 facilitates the synchronous drainage of pus around the drainage holes 106, thereby improving the drainage efficiency of the pus.

[0029] The drainage tube body 1 in the present application is also provided with protrusions 107 along the drainage hole 106 ; the setting of the protrusions 107 effectively prevents the drainage hole 106 from being directly adsorbed on the tissue of the affected area, prevents the drainage hole 106 from being blocked by the tissue of the affected area, and ensures the drainage effect of the drainage hole 106 .

[0030] Example 2: Figure 2As shown, in order to ensure that the drainage tube body 1 can be smoothly inserted into the abscess, the drainage end 101 in the present application is provided with a puncture portion 1011, and the puncture portion 1011 is a pointed structure, which is convenient for improving the efficiency of the drainage tube body extending into the abscess; preferably, the puncture portion 1011 in the present application is made of hard material to ensure the structural shape of the puncture portion 1011, avoid deformation of the puncture portion 1011 during the puncture process, and ensure the puncture efficiency of the drainage tube body 1.

[0031] As a preferred embodiment, an elastic ring 5 is further provided on the drainage tube body 1 in the present application near the drainage end body, and the elastic ring 5 is arranged from small to large from the drainage end 101 to the connecting end 102, that is, the diameter of the elastic ring 5 near the drainage end 101 is smaller than the diameter near the connecting end 102, that is, when the drainage end 101 is extended into the abscess, the smaller end of the elastic ring 5 first extends into the abscess area, and as the drainage end 101 is extended, the entire elastic ring 5 is driven to extend into the abscess, and the elastic ring structure with one end large and the other end small, after the drainage end 101 is extended into the abscess, the elastic ring 4 at the larger end realizes the limiting fixation of the drainage tube body 1, maintains the stability of the drainage tube body 1 inserted into the abscess in the absence of external force, prevents the drainage tube body 1 from falling out in the abscess area, and ensures the stability of drainage of pus in the abscess.
