[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-5As shown, an abdominal binder for preventing parastomal hernia with dynamic pressure regulation includes an abdominal binder body 1. Two fixing waistbands 2 are symmetrically fixed on both sides of the abdominal binder body 1. One fixing waistband 2 has a hook face 10 fixed to one end, and the other fixing waistband 2 has a rough surface 11 fixed to its side wall, which cooperates with the hook face 10. The two fixing waistbands 2 can be fixed together by the cooperation of the hook face 10 and the rough surface 11, and the tightness of the abdominal binder body 1 can be adjusted. The abdominal binder body 1 has a stoma hole 3. A fixing airbag 8 is fixed to the inner wall of the abdominal binder body 1. The fixing airbag 8 is in contact with the abdomen. The fixing airbag 8 has a mesh structure to facilitate ventilation and improve the comfort of the patient when wearing the abdominal binder. There can be one or more fixing airbags 8. Pressure transmitters are embedded on the side of the fixing airbag 8 facing the patient's abdomen. Sensor 9 is used to detect the pressure value between the human body and the abdominal binder. The pressure sensor 9 is model SBA-S. An automatic pressure relief valve is embedded in the side wall of the fixation airbag 8. A whistle that can emit an alert sound is installed in the air outlet of the automatic hydraulic valve. When the fixation airbag 8 is compressed to the set pressure, the automatic pressure relief valve opens automatically, and the gas in the fixation airbag 8 is discharged. The whistle then emits an alert sound to remind medical staff and patients to pay attention to the usage procedures. The side wall of the fixation airbag 8 is formed with inflation holes for easy gas replenishment. A control box 4 is fixed to the front surface of the abdominal binder body 1. The control box 4 contains a control module 41 electrically connected to the pressure sensor 9 and a battery 42. The control module 41 uses an STC89C51 microcontroller. The STC89C51 uses an 8051 core ISP (In-System Programmable Components) The system-programmable chip (ISP) has a maximum operating clock frequency of 80MHz and contains 8KB of Flash read-only memory that can be repeatedly erased and rewritten 1000 times. The device is compatible with the standard MCS-51 instruction set and 80C51 pinout. It integrates a general-purpose 8-bit central processing unit and an ISP Flash memory unit, featuring in-system programmability (ISP). The battery 42 is a rechargeable lithium battery. A charging socket electrically connected to the battery 42 is formed on the side wall of the control box 4. Inside the control box 4 is a miniature air pump 43 electrically connected to the control module 41 and the battery 42. The miniature air pump 43 is connected to a movable airbag 6 via a connecting air tube 5. The movable airbag 6 can automatically change shape to fit the waist of the body. The miniature air pump 43 can inflate the movable airbag 6. The connecting air tube 5 includes… The protective sleeve contains an inflation tube and a deflation tube. An exhaust valve 44, electrically connected to the control module 41 and the battery 42, is fixed to the exhaust tube. By controlling the opening and closing of the exhaust valve 44, the air pressure of the movable airbag 6 can be adjusted, thereby regulating the pressure between the abdominal binder body 1 and the patient's abdomen. A human-machine interface module 45, electrically connected to the control module 41 and the battery 42, is embedded in the front surface of the control box 4. The human-machine interface module 45 includes control buttons and a display screen. The control buttons are used to issue control commands.The display screen is used to show information such as battery level and pressure.

[0024] In this embodiment, the active airbag 6 is composed of multiple cylindrical airbags connected together to form a flexible plate-like structure, which is convenient to be set around the waist and improves the comfort during use.

[0025] In this embodiment, an anti-slip device 7 is fixed to the upper end of the abdominal binder body 1 to prevent the abdominal binder body 1 from accidentally falling off. The anti-slip device 7 includes a connecting strap 71 fixed to the abdominal binder body 1. There are at least two connecting straps 71. An anti-slip fixing strap 72 is fixed to one end of the connecting strap 71 away from the abdominal binder body 1. The two ends of the anti-slip fixing strap 72 are respectively fixed with a buckle plug 73 and a buckle socket 74 that can be fastened together. The length of the anti-slip fixing strap 72 is adjustable. The anti-slip fixing strap 72 can be an elastic strap or a nylon woven bag with an adjustment buckle. After the anti-slip device 7 is fixed, if the connection of the waist belt 2 is accidentally broken, the anti-slip device 7 can be used to prevent the abdominal binder body 1 from falling off or moving in a large range, affecting its use and causing inconvenience to the patient.

[0026] In this embodiment, the length of the connecting strap 71 is adjustable, which makes it easy to adjust the distance between the abdominal belt body 1 and the anti-slip fixing strap 72, ensuring that the connecting strap 71 is taut after the anti-slip fixing strap 72 is fixed, so as to play the role of preventing slippage.

[0027] The working principle of this utility model is as follows: When in use, align the stoma hole 3 with the patient's stoma, and then use the cooperation of the hook surface 10 and the rough surface 11 to fix the abdominal binder to the patient's waist, keep the connecting strap 71 taut, adjust the length of the anti-slip fixing strap 72 so that the anti-slip fixing strap 72 wraps around the patient's waist and the rear ends are fixed together, insert the movable airbag 6 into the gap between the patient's back and the fixing waist belt 2, and then start the power through the human-machine interaction module 45. The control module 41 controls the micro air pump 43 to work to inflate the movable airbag 6, causing it to expand and thus tighten the fixing waist belt 2, so that the abdominal binder body 1 can support the patient's abdomen and exert a certain pressure on the abdomen. The pressure sensor 9 detects the pressure between the fixing airbag 8 and the abdomen. When the set value is reached, stop inflating the movable airbag 6. Then, when the patient moves or changes body position, the control module 41 automatically adjusts the inflation and deflation of the movable airbag 6 according to the detection result of the pressure sensor 9 to achieve dynamic adjustment of the pressure of the abdominal binder on the abdomen.

[0028] The circuit connection involved in this utility model is a common method used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments. It belongs to the widely used prior art.

[0029] Components not described in detail in this article are existing technologies.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
