Detailed ways

The invention provides a physical defecation device, which can ensure the smooth discharge of stools of patients with constipation, and solves the time-consuming and labor-intensive problem of the traditional manual deduction method. The present invention also designs an independent sewage discharge channel to uniformly collect the soft stools and sewage generated during the defecation process through the sewage discharge channel, ensuring the cleanliness of the operation process, simplifying the cleaning process after treatment, and reducing the number of nursing staff. workload.

Referring to Fig. 1-Fig. 12, the present invention mainly includes stirring rod 1, sewage collection sleeve 2, depth control plate 3, tubular handle 6, sewage pipe 7, clear water pipe 8, water storage tank 9, water pump 14, quick connector 15, driving motor 16. Swivel tube 18, transition tube 21, connecting tube 22, anal wall protection sheath 27. Wherein, the drive motor 16 adopts a hollow shaft motor, such as the hollow elf 4 motor in the pulse tower GB1608 brushless DC miniature servo pan-tilt series motor, the rotor of this motor is tubular, and the liquid can flow through the rotor. The drive motor 16 has good The waterproof function allows sewage to flow through the gap between the motor and the tubular handle 6. The main function of the driving motor 16 is to drive the stirring rod 1 to rotate, so as to disperse the hard stools that cause constipation. The water pump 14 is used to send the clear water or liquid medicine stored in the clear water cavity 13 of the water storage tank 9 into the water inlet of the stirring bar 1 rear end through the clear water pipe 8, the connecting pipe 22, the rotary pipe 18, the hollow shaft 25 of the drive motor 16, and then Spray on the hard stool by the water spray hole 26 to soften the hard stool. The soft stools and sewage that produce enter the sewage chamber 10 in the water storage tank 9 through the sewage collection cover 2, the tubular handle 6, and the sewage pipe 7. The nursing staff holds the tubular handle 6 to carry out defecation operation. The tubular handle 6 is provided with a rotation speed adjustment key 4 and a bowel mode selection key 5. The rotation speed adjustment key 4 is used to control the rotation speed of the driving motor 16, thereby controlling the rotation speed of the stirring rod 1 . The bowel moistening 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.

The depth-limiting plate 3 is used to limit the insertion depth of the stirring rod 1 to prevent injury to the patient. The depth-limiting plate 3 is fixedly connected with the tubular handle 6 through locking screws, and the installation position of the depth-limiting plate 3 on the tubular handle 6 can be adjusted through the locking screws.

The stirring rod 1 is used to stir the hard stool in the intestinal tract to break it up, and the rotating speed of the stirring rod 1 is adjusted by pressing the rotating speed adjustment key 4 in FIG. 1 . According to different forms and characteristics of hard stools, the present invention provides three types of agitating rods, and patients can choose a suitable agitating rod according to their actual conditions.

The stirring rod 1 shown in Figure 4 is a peristaltic and lubricating stirring rod, which is mainly used to remove spherical dry stools that have not been discharged for several days. This type of stool is discontinuous and is an independent individual one by one. This stirring rod 1 is There is a curved rod with spherical protrusions in the front, which can massage and expand the anus. It can simulate the movement of fingers in clinical practice to stimulate defecation. The curved rod drives the spherical protrusions to slowly rotate on the intestinal wall. At the same time, there is a or A plurality of water spray holes 26 can spray water or lubricating liquid to assist in the lubrication of the intestinal wall and infiltrate the spherical dry stool at the same time. When the agitating rod rotates, it can relax the lifting muscle and stimulate the defecation stress response, thereby ensuring smooth stool discharge. In order to adapt to the intestinal depth of different patients, except for the most front spherical protrusions, the rest of the spherical protrusions are designed to be detachable, and the number can be adjusted according to the user's individual feelings.

The stirring bar shown in Fig. 6 and Fig. 10 is to stir and break up the type stirring bar, and the front end of the stirring bar 1 among Fig. 1. A birdcage-shaped toilet head 31 is provided at the front end, and the birdcage-shaped toilet head 31 is made of a material with good elasticity, so that it can be inserted into the anal wall protective sheath 27 after being tightened.

Stirring and dispersing stirring rods are suitable for patients with dry stools with hard stool heads and patients with non-organic intestinal obstruction. This type of stool is continuous, but usually the strip-shaped stool head is extremely hard, and it is difficult to pass water and drugs. To relieve the symptoms of constipation, usually the hard part can only be manually buckled to ensure normal excretion.

The rotating speed of agitating and breaking up type agitating rod is relatively fast, and its external sheath is equipped with anal wall protection sheath 27, to protect the patient's anus and intestinal tract, anus wall protection sheath 27 front portion is provided with a plurality of toilet holes 28, anal wall protection The sheath 27 extends into the hard feces in the intestinal tract, and by shaking the anal wall protective sheath 27, part of the hard feces can enter the anal wall protective sheath 27 through the stool hole 28, and pass through the spiral blade 30 or the birdcage-shaped toilet head 31 in the anus. The rapid rotation in the wall protection sheath 27 and the spraying of liquid in the anal wall protection sheath 27 can quickly disperse and soften hard stools, and promote defecation. Wherein the helical blade 30 and the birdcage-shaped toilet bowl 31 can be used in common, and the number of birdcages of the birdcage-shaped toilet bowl 31 is preferably one or two.

The front end edge of collecting dirt cover 2 withstands patient's anus around, and its effect is to collect soft stools and sewage produced in the defecation process, prevents soft stools and sewage from polluting bedding after leaking. The anal wall protection sheath 27 is non-rotatable, and it is connected together with the dirt collection sleeve 2 through a radial connecting plate 29 .

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