Technical Field
The invention belongs to the field of urination auxiliary appliances of urethral catheterization, and particularly relates to an automatic opening and closing and delay device for a catheter.
Background
The urethral catheterization is an auxiliary diagnosis or treatment for guiding urine out by inserting the catheter into the urinary bladder through the urethra under the principle of aseptic operation, and can also be used for urination patients with difficulty. The main indications are as follows: 1. commonly used for urinary retention; 2. culturing the bacteria by urine; 3. detecting whether the urethra has stenosis or not, and preparing the pelvic organs before operation.
When urinary catheterization is needed for some diseases or operations, and a catheter is left, a mode of timed urination and open drainage urination is generally adopted clinically. However, the mode breaks the normal urination mode, especially the open drainage urination mode, so that the intermittent urination activity is changed into the continuous process corresponding to the generation of urine in the kidney, the bladder storage function is wasted, the urination reflection is interrupted, the bladder is in a vacant state, the bladder gradually adapts to the inert state of urine flow, and the active urination consciousness cannot be timely established even after tube drawing. Intermittent and timed urination can not be realized by people, and the bladder filling speed, pressure and urination interval time can not be mastered. If urine in the bladder is small, the urine is insufficient to cause the urine meaning, the urine flows out along with the action of pressure difference, the patient is difficult to generate the urination feeling, and the active urination consciousness cannot be established in time after tube drawing.
The above problems leave the bladder in an empty state and the detrusor muscle of the bladder is disused and atrophied, resulting in contracture of the bladder. Clinical manifestations: patients often develop varying degrees of urinary, fecal, frequent, urgent, intolerable distending or spastic pain in the bladder and perineum areas. The bladder is not washed smoothly, even the flushing liquid flows back, the blood color of the flushing liquid is deepened, urine overflows around the catheter, and the like.
