For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0028] The following is a further description of the present utility model in conjunction with the attached Figures 1-7 diagrams.

[0029] To solve the problems existing in the background technology, the present application proposes the following technical solutions: including a fixed box 1, a film dressing is arranged at a position of the fixed box 1 close to the patient's buttocks, and the fixed box 1 is fixed to the patient's buttocks by the adhesiveness of the film dressing. A fixed block 6 is rotatably installed at the inner bottom of the fixed box 1. Two sets of installation grooves 7 are formed in the fixed block 6. Slide rods 8 are slidably installed in both sets of installation grooves 7. Through holes 5 are formed in both the fixed box 1 and the fixed block 6. Guide blocks 12 are arranged at one ends of the two slide rods 8 away from the through holes 5. The guide blocks 12 are arranged in an arc structure and are fixed to the inner bottom of the fixed box 1. Clamping blocks 9 are fixedly installed at one ends of the two slide rods 8 located in the through holes 5. A pressure measuring catheter 2 is arranged between the two clamping blocks 9. One end of the pressure measuring catheter 2 is fixedly connected to a pressure measuring airbag 3, and the pressure measuring airbag 3 is used for measuring the rectal muscle pressure. A rotating cylinder 13 is fixedly installed on the fixed block 6. The upper end of the rotating cylinder 13 is located outside the fixed box 1, and at the same time, the rotating cylinder 13 is rotatably connected to the fixed box 1. A locking mechanism is arranged in the fixed block 6.

[0030] During anal pressure measurement, through the film dressing arranged on one side of the fixed box 1, the fixed box 1 is fixedly pasted at the position of the patient's buttocks, so that the through hole 5 on the fixed box 1 is aligned with the anus. Then, the pressure measuring airbag 3 is inserted into the rectal position inside the patient's anus through the through hole 5 on the fixed box 1 through the pressure measuring catheter 2. The upper end of the rotating cylinder 13 is rotated counterclockwise by hand. The rotating cylinder 13 drives the fixed block 6 to rotate. The fixed block 6 drives the slide rod 8 to rotate. The slide rod 8 moves along the arc surface of the guide block 12. The slide rod 8 moves towards the direction close to the through hole 5. The slide rod 8 drives the clamping block 9 to move. The two clamping blocks 9 clamp and fix the pressure measuring catheter 2 in the through hole 5. The locking mechanism can lock the fixed block 6, so as to firmly fix the pressure measuring catheter 2 in the two clamping blocks 9, avoid the displacement or loosening of the pressure measuring catheter 2 during the anal pressure measurement process, resulting in fluctuations in the measured pressure data, and ensure the accuracy of the measured pressure data.

[0031] Further, the locking mechanism includes a ratchet 14 fixedly sleeved outside the rotating cylinder 13, a pawl 15 rotatably installed on the inner top wall of the fixed box 1, and an elastic spring piece 16 arranged on one side of the pawl 15. The pawl 15 is adapted to the ratchet 14, and one end of the elastic spring piece 16 is fixedly installed on the inner top wall of the fixed box 1.

[0032] During the process of fixing the pressure measuring catheter 2, the rotating cylinder 13 simultaneously drives the ratchet 14 to rotate counterclockwise. The pawl 15 and the ratchet 14 are engaged with each other. The pawl 15 prevents the ratchet 14 from rotating clockwise in the opposite direction, so that the rotating cylinder 13 can only drive the fixed block 6 to rotate counterclockwise. After the two clamping blocks 9 firmly fix the pressure measuring catheter 2, the rotating cylinder 13 is released, and the fixed block 6 will not rotate clockwise, so as to fix the position of the clamping block 9 and ensure the fixation of the pressure measuring catheter 2. The arrangement of the elastic spring piece 16 enables the pawl 15 to always be engaged with the ratchet 14, improving the stability of the locking mechanism during use.

[0033] It is further explained that a connecting rod 17 is fixedly connected to the pawl 15 , and the connecting rod 17 passes through the fixed box 1 and is rotatably connected to the fixed box 1 . A paddle 18 is rotatably installed on the fixed box 1 , and the bottom of the paddle 18 is fixedly connected to the upper end of the connecting rod 17 .

[0034] After the anal pressure measurement is completed, the paddle 18 is toggled, and the paddle 18 drives the pawl 15 to rotate through the connecting rod 17, so that the pawl 15 rotates from the position of the ratchet 14. At this time, the pawl 15 is no longer engaged with the ratchet 14, and the rotating drum 13 can rotate freely. The rotating drum 13 can be rotated clockwise to allow the sliding rod 8 to drive the clamping block 9 to move away from the pressure measuring catheter 2. The two groups of clamping blocks 9 no longer fix the pressure measuring catheter 2, and the pressure measuring catheter 2 can be pulled out of the patient's anus.

[0035] It is further explained that baffles 10 are fixedly installed on both sides of the slide rod 8, a return spring 11 is fixedly connected to one side of the baffle 10, and one end of the return spring 11 away from the baffle 10 is fixedly installed on the inner wall of the installation groove 7.

[0036] When fixing the pressure measuring tube 2, the slide bar 8 drives the clamping block 9 to move toward the pressure measuring tube 2, and the baffle 10 compresses the reset spring 11. After the pressure measurement is completed, when the rotating drum 13 is rotated clockwise, the rotating drum 13 drives the elastic spring 16 to rotate clockwise, and the compressed reset spring 11 drives the slide bar 8 to move away from the pressure measuring tube 2 to restore the initial state. The slide bar 8 drives the clamping block 9 to move, so that the clamping block 9 is automatically reset, which is convenient for the next use of the device and improves the practicability of the device.

[0037] It is further explained that an anti-slip strip 19 is fixedly connected to the circumferential surface of the upper end of the rotating drum 13 , and the anti-slip strip 19 is arranged outside the fixed box 1 .

[0038] The provision of the anti-slip strip 19 increases the friction between the hand and the rotating drum 13, making it more labor-saving when rotating the rotating drum 13, thereby improving the convenience of using the device.

[0039] It is further explained that a waterproof dressing 4 is fixedly installed on the outside of the fixing block 6. The waterproof dressing 4 is made of a flexible material, and a film dressing is also provided on the side of the waterproof dressing 4 close to the patient's buttocks. The film dressing has good compliance and self-adhesiveness, and can be closely attached to the skin of the patient's buttocks without being easy to fall off. The waterproof dressing 4 serves to reinforce the fixing box 1 on the patient's buttocks and effectively prevent it from falling off, further improving the fixing effect of the pressure measuring catheter 2, and at the same time effectively preventing the patient from defecating after anal force during the pressure measurement process, thereby improving the practicality of the device.

[0040] The specific operation is as follows: when performing anal pressure measurement, the fixed box 1 is fixed to the patient's buttocks by the waterproof patch 4, so that the perforation 5 on the fixed box 1 is aligned with the anus, and then the pressure measuring airbag 3 is inserted into the rectum position inside the patient's anus through the perforation 5 on the fixed box 1 through the pressure measuring catheter 2, and the upper end of the rotating drum 13 is rotated counterclockwise by hand, and the rotating drum 13 drives the fixed block 6 to rotate, and the fixed block 6 drives the sliding rod 8 to rotate, and the sliding rod 8 moves along the arc surface of the guide block 12, and the sliding rod 8 moves toward the perforation 5. The rod 8 drives the clamping block 9 to move, and the two groups of clamping blocks 9 clamp and fix the pressure measuring tube 2 in the perforation 5. In the process of fixing the pressure measuring tube 2, the rotating cylinder 13 drives the ratchet 14 to rotate counterclockwise at the same time, and the pawl 15 and the ratchet 14 are engaged with each other. The pawl 15 prevents the ratchet 14 from rotating clockwise in the opposite direction, so that the rotating cylinder 13 can only drive the fixing block 6 to rotate counterclockwise. If the rotating cylinder 13 is released, the fixing block 6 will not rotate clockwise, thereby fixing the position of the clamping block 9 and ensuring the fixing effect of the pressure measuring tube 2.

[0041] After the anal pressure measurement is completed, the paddle 18 is toggled, and the paddle 18 drives the pawl 15 to rotate through the connecting rod 17, so that the pawl 15 rotates from the position of the ratchet 14. At this time, the pawl 15 is no longer engaged with the ratchet 14, and the rotating drum 13 can rotate freely. The rotating drum 13 is rotated clockwise to make the sliding rod 8 drive the clamping block 9 to move away from the pressure measuring catheter 2. The two groups of clamping blocks 9 no longer fix the pressure measuring catheter 2, and the pressure measuring catheter 2 can be pulled out of the patient's anus.
