[0021] 3. By setting the flipping and cutting-off mechanism and the active anal dilation mechanism, the feces can be assisted to be cut off during the defecation process, thus facilitating the defecation operation and making the defecation effect better. And the flipping and cutting-off angle of the cutting-off plate can be automatically regulated based on the dilation degree. On the premise of ensuring that the feces can be cut off, the problem that too large a flipping angle will cause multiple cutting-off plates to rigidly collide with each other and cause damage is avoided.

[0022] In summary: The present invention can pre-regulate the use intensity of the defecation device according to the patient's physical condition, and then automatically regulate the single insertion depth, total insertion depth, dilation speed, and final dilation degree of the defecation device. On the premise of meeting the patient's physical use intensity, the defecation efficiency is improved as much as possible to ensure the defecation quality. And this process does not require active manipulation by medical staff, and can realize efficient automatic defecation work. Each defecation process cooperates with each other to achieve more efficient defecation work, with lower requirements for the professionalism and experience of medical staff and better applicability.

[0031] As Figures 1-6 shown, a defecation device for digestive surgery nursing includes a base 1.

The lower end of the seat plate 8 is fixedly embedded with a third laser rangefinder 9.

The pushing and inserting mechanism 2 includes four electric push rods 21 symmetrically fixedly installed on the upper end of the base 1. The upper movable ends of the two electric push rods 21 on the same side are fixedly connected to the same L-shaped lifting plate 22, and the lower ends of the two L-shaped lifting plates 22 are integrally connected to the same supporting plate 23.

[0033] The active anal expansion mechanism 3 is mounted on the pushing and inserting mechanism 2, and the surface of the seat plate 8 is provided with a through hole for the top end of the active anal expansion mechanism 3 to extend through. The active anal expansion mechanism 3 includes a plurality of fixed shells 31 symmetrically fixedly mounted on the upper end of the support plate 23 and arranged in an annular distribution. A rotating screw 32 is rotatably connected in the fixed shell 31, and a push-pull plate 33 is threadedly sleeved on the rod wall of the rotating screw 32. The side wall of the push-pull plate 33 is symmetrically fixedly connected to a plurality of push-pull rods 34. One end of the plurality of push-pull rods 34 away from the push-pull plate 33 extends out of the fixed shell 31 and is fixedly connected to the same anal expansion plate 35. The upper end of the anal expansion plate 35 is set as an arc structure, and the lower end of the support plate 23 is fixedly provided with a cover shell 3 6. The lower end of the support plate 23 is rotatably connected to a plurality of transmission shafts 37 arranged corresponding to the position of the fixed shell 31 through a bearing seat. One end of the transmission shaft 37 is connected to one end of the rotating screw 32 through a sprocket assembly 38. A servo motor 39 is fixedly installed on the bottom of the inner wall of the cover shell 36. The upper output end of the servo motor 39 is connected to the plurality of transmission shafts 37 through a bevel gear assembly 310. The lower end side walls of the plurality of anal expansion plates 35 are detachably connected with the same elastic storage bag 311. A second laser rangefinder 312 is fixedly inserted into the side wall of one of the fixed shells 31. The second laser rangefinder 312 is arranged opposite to the push-pull plate 33 to monitor the moving distance of the anal expansion plate 35.

[0034] Multiple groups of flipping and pinching mechanisms 4 are installed on the upper side of the inner wall of the active anal dilation mechanism 3. The flipping and pinching mechanisms 4 include a flipping motor 41 embedded in the upper side wall of the anal dilation plate 35. One side output end of the flipping motor 41 is fixedly connected to an extension plate 42. One side of the extension plate 42 is fixedly connected to a pinching plate 43. The pinching plate 43 is also embedded in the inner side wall of the anal dilation plate 35.

[0035] The operating degree preset mechanism 5 is fixedly mounted on the column wall of the support column 7. The operating degree preset mechanism 5 includes a preset shell 51. The inner wall of the preset shell 51 is rotatably connected with an adjusting screw 52. The upper end of the adjusting screw 52 passes through the upper end of the preset shell 51 and is fixedly connected with an adjusting handle 53. The rod wall of the adjusting screw 52 is threadedly sleeved with an adjusting plate 54. An identification scale plate 55 is fixedly mounted on one side of the preset shell 51. A pointer 56 is fixedly connected to one side of the adjusting plate 54. The end of the pointer 56 away from the adjusting plate 54 passes through the outside of the preset shell 51 through a strip opening 57 opened on the side wall of the preset shell 51 and is arranged on one side of the identification scale plate 55. A first laser rangefinder 58 is fixedly inserted at the bottom end of the preset shell 51.

[0036] The single - insertion depth control mechanism 6 is fixedly installed at the upper end of the base 1 and is electrically connected to the operation - degree presetting mechanism 5. The single - insertion depth control mechanism 6 includes a trigger circular shell 61. A middle shaft 62 is rotatably connected to the center of the inner wall of the trigger circular shell 61. A reduction motor 63 for driving the middle shaft 62 to rotate self - is fixedly installed at the lower end of the trigger circular shell 61. A position - in - place switch 64 is fixedly installed on one side of the inner wall of the trigger circular shell 61. An arc - shaped trigger block 65 corresponding to the position of the position - in - place switch 64 is fixedly connected to the shaft wall of the middle shaft 62.

[0037] Now, the operation principle of the present invention is described as follows: Let the patient sit on the seat plate 8 so that the patient's anus is aligned with the positions of the plurality of anal dilator plates 35 (the surface of the anal dilator plates 35 is pre - sprayed with lubricant, and the anal dilator plates 35 are made of silica gel). According to the patient's physical condition, the medical staff manually operate the adjusting handle 53 to drive the adjusting screw 52 to rotate. Through the threaded socket connection between the adjusting screw 52 and the adjusting plate 54, the adjusting plate 54 drives the pointer 56 to move, and then the pointer 56 changes its position relative to the identification scale plate 55. The adjustment state can be determined according to the position of the pointer 56 relative to the identification scale plate 55. And the first laser rangefinder 58 monitors the position from the adjusting plate 54 and feeds back the distance information to the PLC controller. Specifically, when the patient's physical condition is better and can withstand a greater intensity of defecation work, the distance that the adjusting plate 54 moves upward is greater, so that the distance between the first laser rangefinder 58 and the adjusting plate 54 is larger, and the first laser rangefinder 58 feeds back a larger distance signal to the PLC controller;

[0038] The PLC controller first regulates the working power of the servo motor 39 based on the distance signal fed back by the first laser rangefinder 58. When the patient's physical condition is better and the first laser rangefinder 58 feeds back a larger distance signal, the PLC controller controls the servo motor 39 to work at a higher power, thereby increasing the anal dilation speed. The servo motor 39 drives multiple transmission shafts 37 to rotate synchronously through the bevel gear assembly 310, and then through the sprocket assembly 38, the transmission shafts 37 drive multiple rotating screws 32 to rotate synchronously. Through the threaded socket connection between the rotating screw 32 and the push-pull plate 33, the push-pull plate 33 cooperates with the push-pull rod 34 to drive the anal dilation plate 35 to move outward, causing the multiple anal dilation plates 35 to move away from each other, thereby dilating the patient's anus. Moreover, a torque sensor is provided in the servo motor 39. When the torque signal fed back by the torque sensor reaches the preset threshold, the PLC controller controls the servo motor 39 to stop working, completing the anal dilation work. And the PLC controller automatically regulates the preset threshold of the torque sensor in the servo motor 39 according to the distance signal fed back by the first laser rangefinder 58. When the patient's physical condition is better, the PLC controller makes the preset threshold of the torque sensor in the servo motor 39 larger, resulting in a greater final anal dilation degree for the patient, making it more convenient for defecation. And for patients with poor physical conditions, it can automatically regulate to reduce the anal dilation speed and the final anal dilation degree to avoid the problem that excessive anal dilation intensity may cause damage to the patient's body;

[0039] During defecation, the PLC controller controls the electric push rod 21 to push the L-shaped lifting plate 22 and the supporting plate 23 to drive the active anal dilation mechanism 3 to move upward, so that the active anal dilation mechanism 3 gradually penetrates into the patient's anus. And when the electric push rod 21 is working, the PLC controller synchronously controls the reduction motor 63 to work. The reduction motor 63 drives the arc-shaped trigger block 65 to move in the trigger circular shell 61 through the intermediate shaft 62 until the arc-shaped trigger block 65 presses on the in-place switch 64. At this time, the PLC controller synchronously controls the reduction motor 63 and the electric push rod 21 to stop moving, realizing the control of the single insertion depth. Specifically, when the patient's physical condition is better and the distance signal fed back by the first laser rangefinder 58 is larger, the PLC controller controls the reduction motor 63 to work at a lower power, thereby making the moving speed of the arc-shaped trigger block 65 slower, and then making the interval time when the arc-shaped trigger block 65 presses on the in-place switch 64 longer, and then making the single working time of the electric push rod 21 longer, so that the depth of pushing the active anal dilation mechanism 3 into the patient's anus is greater;

[0040] Each time the active anal dilation mechanism 3 moves deeper, the PLC controller controls the flip motor 41 to move. The flip motor 41 drives the extension plate 42 to drive the pinching plate 43 to flip, so that the multiple pinching plates 43 pinch off the feces, so that the feces automatically fall into the elastic storage bag 311 for collection, and the large pieces of feces are divided into small pieces, which can reduce the resistance to feces discharge. Even if the intestinal peristalsis is weak, small pieces of feces are easier to pass through the expanded anus, thereby assisting the patient to defecate. An angle sensor is provided in the flip motor 41, which can monitor the rotation angle of the flip motor 41 and feedback the signal to the user. The PLC controller, when the anal dilation work on the patient's anus reaches the final state, the second laser rangefinder 312 monitors the distance between the push-pull plate 33, and can then feedback the movement distance of the anal dilation plate 35. When the movement distance of the anal dilation plate 35 is greater, the distance signal feedback by the second laser rangefinder 312 is smaller. At this time, the PLC controller controls the flip motor 41 to drive the pinching plate 43 to flip to a larger angle. Because the greater the movement distance of the anal dilation plate 35, the greater the distance between the multiple anal dilation plates 35. The multiple pinching plates 43 need to flip to a larger angle in order to collide with each other to pinch off the stool;

[0041] And based on the distance signal fed back by the first laser rangefinder 58 in the preset mechanism 5 in the degree of operation, the PLC controller automatically adjusts the monitoring threshold of the third laser rangefinder 9. In the process of the electric push rod 21 pushing the active anal expansion mechanism 3 to move deep into the patient's anus, when the third laser rangefinder 9 detects that the distance from the L-shaped lifting plate 22 reaches the threshold, the PLC controller promptly controls the electric push rod 21 to stop the action and drives the flipping and cutting off mechanism 4 to complete the laxative work on the last side. Specifically, the better the patient's physical condition and the stronger his tolerance, the more the PLC controller controls the third laser rangefinder 9 to move upward and deeply into the patient's anus. The smaller the monitoring minimum distance threshold set by the optical rangefinder 9, the deeper the defecation depth can be achieved by the active anal dilation mechanism 3, making the defecation more thorough. For patients in poor physical condition, the larger the monitoring minimum distance threshold set by the PLC controller to the third laser rangefinder 9 is, the smaller the final defecation depth of the active anal dilation mechanism 3 is, avoiding the problem of causing excessive and inappropriate damage to the patient's body, and realizing efficient automatic defecation. The various defecation processes cooperate with each other to achieve more efficient defecation, with lower requirements on the professionalism and experience of medical personnel and better applicability.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
