The present invention proposes a physical defecation device, which ensures smooth evacuation of constipated patients and solves the troublesome problem of the traditional disimpaction method. In the present invention, an independent waste discharge passage is also designed, and the loose stool and sewage generated during the feces treatment process are collected together in the waste discharge passage, which not only ensures the cleanliness of the operation process, but also The cleaning process will also be simplified, reducing the burden on nurses.

Referring to FIGS. 1 to 12, the present invention mainly includes a stirring rod 1, a waste collection cover 2, a depth limiting disc 3, a tubular handle 6, a waste discharge hose 7, and a washing water hose. 8, a water storage tank 9, a water pump 14, a quick joint 15, a drive motor 16, a rotation pipe 18, a transition pipe 21, a connection pipe 22, and an anal wall protection sheath 27. The drive motor 16 uses a hollow motor, such as a hollow Elf 4 motor in a Myactuator GB1608 brushless DC miniature servo head series motor, the rotor of which is tubular so that liquid can flow through the rotor. , the drive motor 16 has good waterproof function, and the dirty water can flow through the gap between the motor and the tubular handle 6. The drive motor 16 mainly functions to rotate the stirring rod 1 to crush hard stools that cause constipation. The water pump 14 pumps the cleaning water or chemicals stored in the cleaning water chamber 13 of the water storage tank 9 by the cleaning water hose 8 , the connecting pipe 22 , the rotary pipe 18 , and the hollow shaft 25 of the drive motor 16 after the stirring rod 1 . It is used to feed the liquid into the inflow hole at the end and then spray the hard stool from the injection hole 26 to soften the hard stool. The generated loose stool and sewage enter the sewage chamber 10 in the water storage tank 9 via the sewage collection cover 2, the tubular handle 6, and the sewage discharge hose 7. The nurse performs defecation operations by grasping the tubular handle 6. The tubular handle 6 is provided with a rotation speed adjustment button 4 and an intestinal lubrication mode selection button 5, and the rotation speed adjustment button 4 controls the rotation of the drive motor 16. By controlling the number, it is used to control the rotation speed of the stirring rod 1. The intestinal lubrication mode selection button 5 is used to control the operating mode of the water pump 14, thereby controlling the water fountain speed of the stirring rod 1, and operating the electric waste cup in a cleaning mode or a lubrication mode.

The depth limiting disc 3 is used to limit the insertion depth of the stirring rod 1 so as not to injure the patient. The depth limiting disk 3 is fixedly connected to the tubular handle 6 via a passing chain screw, and the position where the depth limiting disk 3 is attached on the tubular handle 6 is adjusted via the chain screw. can.

The stirring rod 1 is used to stir and crush hard stool in the intestinal tract. The rotation speed of the stirring rod 1 is adjusted by pressing the rotation speed adjustment button 4 shown in FIG. Based on the shapes and characteristics of different hard stools, the present invention provides three types of stirring rods, and patients can choose the stirring rod suitable for themselves according to the actual situation.

The stirring rod 1 shown in Fig. 4 is a peristaltic lubricated stirring rod, and is mainly used to remove loose stools that have not been excreted for several days.This type of stool is discontinuous and is an independent individual. . This type of stirring rod 1 is a bending rod with a spherical protrusion on the front, which has the effect of massaging and dilating the anus, and can simulate clinical disimpaction. Rotate slowly, and at the same time there is one or more injection holes 26 on the top of the frontmost bulbous projection, which can spray water or lubricant to help lubricate the intestinal wall and infiltrate the stool. As the seed stirrer rotates, it relaxes the anal sphincter and triggers the defecation reflex, ensuring smooth expulsion of stool. In order to adapt to the depth of the intestinal tract of different patients, except for the most anterior bulb, the other bulb designs are removable and the number can be adjusted according to the user's individual sensation.

The stirring rod shown in FIGS. 6 and 10 is a stirring and crushing type stirring rod, and a spiral blade 30 is provided at the front end of the stirring rod 1 in FIG. I can prepare. A birdcage-shaped stool crushing head 31 is provided at the front end of the stirring rod 1 in FIG. Convenient to insert.

Stirring and crushing type stirring sticks are suitable for patients with constipation and non-organic intestinal obstruction, where the tip of the stool is relatively hard.This type of stool is continuous, but the tip of banana-shaped stool is usually particularly hard and does not flow easily. It is difficult to relieve constipation symptoms even through the use of drugs and methods, and normal excretion can only be ensured by scraping out the hard part of the stool with your fingertips.

The rotation speed of the stirring/pulverizing stirring rod is relatively fast, and it is fitted with an anal wall protective sheath 27 to protect the patient's anus and intestinal tract, and has a plurality of fecal passage holes 28 in the front of the anal wall protective sheath 27. By inserting the anal wall protective sheath 27 into hard stool in the intestinal tract and shaking the anal wall protective sheath 27, some of the hard stool can be made to enter the anal wall protective sheath 27 through the stool passage hole 28. By rapidly rotating the spiral blade 30 or birdcage-shaped stool crushing head 31 in the anal wall protective sheath 27 and spraying liquid into the anal wall protective sheath 27, hard stool is quickly crushed, softened, and defecated. can be promoted. The spiral blade 30 and the birdcage-shaped stool crushing head 31 can be used, and the number of birdcages in the birdcage-shaped stool crushing head 31 is preferably one or two.

The front edge of the waste collection cover 2 abuts around the patient's anus, collects loose stool and waste water generated during defecation process, and prevents soiling of bedding after leakage of loose stool and waste water. The anal wall protection sheath 27 cannot rotate and is connected to the waste collection cover 2 via a radial connection plate 29.

Turbine blades 19 are installed on the outer wall of the rotary pipe 18, and when the rotary pipe 18 rotates following the drive motor, it can accelerate the discharge of waste water. The cleaning water hose 8 and the waste discharge hose 7 are coaxial pipes, and the stirring rod 1 and the hollow shaft 25 of the drive motor 16 are connected by a quick joint 15, thereby improving work efficiency.
