Power-assisted urination device and control method

Abstract

The invention discloses a power-assisted urination device and a control method. The power-assisted urination device comprises a urination tube, a plunger pump and a head controller, wherein a positioning air bag is arranged outside the urination tube; the plunger pump comprises a pump body and a plunger, and a magnet exciting coil is arranged outside the pump body; and the head controller comprises a sensor, a processor, a power supply and a shell. The plunger pump is connected with the urination tube, and the urination tube is fixed in the urethra through the positioning air bag. The head controller is used for controlling opening and closing of the plunger pump, and when urination is needed, the head controller controls the plunger pump to be started, so that urine is driven by the plunger pump to flow through the urination tube and then flow out, and the problem of patients with bladder contraction weakness indications can be solved. In addition, due to the fact that the urine has acertain speed when being discharged, the urine can flush the urethra, and the urethra is kept sanitary. The urination tube does not need to extend out of the body, so that the movement convenience ofa user is improved, and the discomfort is reduced; and the urethra can be naturally contracted after urination, so that the contraction function is maintained, and the infection risk is also reduced.

Description

technical field [0001] The invention relates to an auxiliary urinal and a control method in the technical field of medical devices. Background technique [0002] When the function of the bladder nerve and bladder muscle in the human body is impaired, resulting in mechanical obstruction of the outflow tract, it will cause difficulty in urinating, or relaxation of the bladder neck, and even urinary incontinence. Therefore, as early as 1600 years ago, Sun Simiao recorded in "A Thousand Gold Prescriptions" that the "legend" of using scallions for urinary catheterization during anuria was recorded; it was not until 1860 that French doctor Naredon invented the rubber catheter. So far we have double-lumen, triple-lumen, silicone, rubber, super slippery, antibacterial and other catheters to relieve urinary obstruction. [0003] With the growth of the average life expectancy of human beings and the improvement of people's requirements for quality of life, more and more attention has...

AI Technical Summary

Problems solved by technology

Yet existing catheterization mostly is a kind of simple mechanical drainage, with reference to a kind of anti-backflow catheter disclosed in Chinese invention patent CN207980155U, the tail of its catheter stretches out the urinary catheter, and it can be used in postoperative medical treatment. It is easy to cause infection and injury in management, human inferiority complex in humanistic care, and inconvenient to carry in people's social activities
