[0002] With the increasing aging of society, the number of middle-aged and elderly people is growing larger and larger. Due to the increase in age and the decline in organ function, many middle-aged and elderly people have a "common problem", that is, dry and difficult stools. Difficulty in defecation has become a common problem that plagues the majority of middle-aged and elderly patients. Existing treatment options mostly use enema and medication, which are difficult to solve in many cases and ultimately rely on manual defecation methods. However, manual defecation methods are not only time-consuming and labor-intensive, but also unhygienic. Especially for some bedridden constipated patients, manual defecation methods can easily contaminate bedding, thereby increasing the patient's pain and the workload of caregivers. Therefore, it is very necessary to design a device that can quickly and cleanly solve the problem of constipation. Summary of the Invention

DETAILED DESCRIPTION

[0030] The present invention provides a physical defecation device that ensures smooth defecation for constipated patients, eliminating the time-consuming and labor-intensive traditional manual defecation method. The present invention also features an independent drainage channel that collects soft feces and wastewater generated during defecation removal, ensuring cleanliness during the operation while simplifying post-treatment cleaning and reducing the workload of nursing staff.

[0031] See Figures 1-12 The present invention mainly includes an agitator 1, a sewage collection sleeve 2, a depth-limiting plate 3, a tubular handle 6, a sewage pipe 7, a clean water pipe 8, a water storage tank 9, a water pump 14, a quick connector 15, a drive motor 16, a rotary tube 18, a transition tube 21, a connecting tube 22, and an anal wall protective sheath 27. The drive motor 16 is a hollow-shaft motor, such as the hollow Elf 4 motor from the MaiTa GB1608 DC brushless mini-micro servo pan / tilt series. The rotor of this motor is tubular, allowing liquid to flow through the rotor. The drive motor 16 has good waterproof properties, allowing sewage to flow through the gap between the motor and the tubular handle 6. The main function of the drive motor 16 is to drive the agitator 1 to rotate, thereby breaking up hard stool that causes constipation. The water pump 14 is used to deliver the clean water or medicine stored in the clean water chamber 13 of the water storage tank 9 into the water inlet hole at the rear end of the stirring rod 1 through the clean water pipe 8, the connecting pipe 22, the rotary pipe 18, and the hollow shaft 25 of the driving motor 16, and then spray it on the hard stool through the water spray hole 26 to soften the hard stool. The soft stool and sewage produced enter the sewage chamber 10 in the water storage tank 9 through the sewage collection sleeve 2, the tubular handle 6, and the sewage pipe 7. The nursing staff holds the tubular handle 6 to perform the defecation operation. The tubular handle 6 is provided with a speed adjustment key 4 and a bowel movement mode selection key 5. The speed adjustment key 4 is used to control the speed of the driving motor 16, and then control the speed of the stirring rod 1. The bowel movement mode selection key 5 is used to control the working mode of the water pump 14, and then control the water spraying speed of the stirring rod 1, so that the electric defecation head works in the irrigation mode or the lubrication mode.

[0032] The depth limiting plate 3 is used to limit the insertion depth of the stirring rod 1 to prevent harm to the patient. The depth limiting plate 3 is fixedly connected to the tubular handle 6 by a locking screw, and the installation position of the depth limiting plate 3 on the tubular handle 6 can be adjusted by the locking screw.

[0033] The stirring rod 1 is used to stir the hard stool in the intestine and break it up. The speed of the stirring rod 1 is adjusted by pressing Figure 1 According to different hard stool shapes and characteristics, the present invention provides three types of stirring rods, and patients can choose the stirring rod that suits them according to actual conditions.

[0034] Figure 4The stirring rod 1 shown is a peristaltic lubrication stirring rod, which is mainly used to clear ball-shaped dry stool that has not been discharged for several days. This type of stool is discontinuous and is an independent individual. This stirring rod 1 is a curved rod with a spherical protrusion on the front, which has a massage and anal dilation effect. It can simulate the action of finger disturbance to stimulate defecation in clinical practice. The spherical protrusion is driven by the curved rod to slowly rotate on the intestinal wall. At the same time, there are one or more water spray holes 26 on the top of the front spherical protrusion, which can spray water or lubricating fluid to assist in lubricating the intestinal wall and at the same time soak the ball-shaped dry stool. When this stirring rod rotates, it can relax the lifting muscle and stimulate the defecation stress response, thereby ensuring smooth discharge of the stool. In order to adapt to the intestinal depth of different patients, except for the front spherical protrusion, the remaining spherical protrusions are designed to be detachable, and the number can be adjusted according to the individual experience of the user.

[0035] Figure 6 and Figure 10 The stirring rod shown is a stirring and breaking type stirring rod. Figure 6 The front end of the stirring rod 1 is provided with a spiral blade 30, and the spiral blade 30 can be provided with 2 to 6 pieces. Figure 10 A birdcage-shaped toilet head 31 is provided at the front end of the stirring rod 1. The birdcage-shaped toilet head 31 is made of a material with good elasticity and is convenient for tightening and inserting into the anal wall protection sheath 27.

[0036] The stirring and breaking up stirring stick is suitable for patients with dry stools with hard stool heads and patients with non-organic intestinal obstruction. This type of stool is continuous, but the stool head is usually extremely hard. It is difficult to relieve constipation symptoms through water flow and medication. Usually, the hard part can only be manually removed to ensure normal excretion.

[0037] The stirring and breaking up agitator rotates at a high speed. An anal wall protective sheath 27 is encased on its exterior to protect the patient's anus and intestines. The front of the anal wall protective sheath 27 is provided with multiple stool passage holes 28. The anal wall protective sheath 27 is inserted into hard stool in the intestines. By shaking the anal wall protective sheath 27, some hard stool can be forced into the anal wall protective sheath 27 through the stool passage holes 28. The spiral blades 30 or birdcage-shaped stool-breaking head 31 rapidly rotate within the anal wall protective sheath 27, spraying liquid into the anal wall protective sheath 27. This quickly breaks up and softens hard stool, promoting defecation. The spiral blades 30 and birdcage-shaped stool-breaking head 31 are interchangeable, and the birdcage-shaped stool-breaking head 31 preferably has one or two cages.

[0038] The front edge of the sewage collection sleeve 2 is against the patient's anus to collect soft feces and sewage produced during defecation and prevent the soft feces and sewage from leaking out and contaminating the bedding. The anal wall protection sheath 27 is non-rotatable and is connected to the sewage collection sleeve 2 by a radial connecting plate 29.

[0039] The outer wall of the rotary tube 18 is provided with turbine blades 19, which can promote the discharge of sewage when the drive motor rotates. The clean water pipe 8 and the sewage pipe 7 are concentric pipes, and the stirring rod 1 is connected to the hollow shaft 25 of the drive motor 16 by a quick connector 15, which can improve work efficiency.
