Description
Technical Field
The invention relates to an autonomous catheterization device, and belongs to the technical field of medical appliances.
Background
In recent years, along with the development of modern medical technology, medical interventional catheters have been widely used, and the range is gradually expanded, so that the medical level is greatly improved. Catheters are quite common as interventional catheters, where approximately hospitalized patients need indwelling catheters, and where ordinary catheters need 4-8 urethral insertions (120 times per month) per day, and are therefore only suitable for self-insertable patients. Since a conventional urinary catheter may cause a urethral trauma, the conventional urinary catheter cannot be applied to a patient having limited eyesight or cognitive ability. Still other patients may be dislike of repeatedly touching their genital area and are dislike of implanting catheters, which often causes psychological problems and leads to reduced quality of life for the patient, affecting the patient's self-image. Even more serious is the catheter as an invasive procedure, with the associated urinary tract infection of the catheter caused by the indwelling catheter, which is about 40% of nosocomial infections, which occur next to the iatrogenic infections of respiratory tract infections, and which are the fifth leading cause of death in the hospital. It is reported in China that urinary tract infection accounts for 35% of nosocomial infections, next to respiratory tract infection, and 75% -80% are related to the use of urinary catheters. The united states reports up to 40% of the first hospital infections. Once catheter-related urinary tract infections occur, there is a potential for increased medical costs, prolonged hospital stays, increased morbidity and mortality. In addition, it is also the greatest source of bacteremia in hospitalized patients, often resulting in additional use of antibacterial agents. The average annual consumption of dollars in treatment costs of 4.5-5.7 billions is statistically 1-2 days longer than average hospitalization, and more than 2.4-4.5 days longer if the infection causes complex bacteremia. Such infections not only cause great pain to the patient, but also consume additional hygienic resources. The main reason for the urinary tract infection caused by indwelling catheters is that the catheters can inhibit or weaken the normal defense mechanisms of the organism, resulting in the formation of a bacterial film. Therefore, to solve the problem from the source, the catheter needs to be endowed with durable and excellent antibacterial performance to fundamentally reduce the occurrence of urinary tract infection related to the catheter, and has important theoretical and practical significance for improving the success rate of patient treatment and the life quality.

In this way, the hand-held activator III does not need to be contacted and only needs to be close to the urethra, when the urethra pump I can sense the opening signal of the hand-held activator III through magnetic induction, the magnetic induction rotating body 5 starts to rotate, the rotating magnetic induction body 5 and the magnet in the sealing valve 2 can generate rotating speed difference, so that magnetic poles repel each other, the magnetic poles alternately rotate to drive the magnetic induction in the urethra pump to rotate, and meanwhile, the sealing valve 2 is lifted upwards, and urine is quickly discharged out of the body from the urine outlet 7 of the urethra pump I under the action of the drainage blade 4 and the bladder pressure; when the urethral pump I senses the closing signal of the hand-held activator III, the magnetically sensitive rotating body 5 stops rotating, and the sealing valve 2 closes downward, stopping urination.
Fig. 3 is a schematic view of a first use state of the present invention.
The application steps of the invention are as follows:
1) The front end of the boosting device II is arranged at the tail end of the urethral pump I;
2) The urethra pump I is integrally inserted into the female urethra, and the anti-falling valve 6 is opened through the push-assisting rod 9;
3) Separating the push-assisting rod to enable the urethral pump to be placed in the urethra;
4) The hand-held activator III approaches to the urethra, the control switch 11 of the hand-held activator III is turned on, when the urethra pump I senses the turning-on signal of the hand-held activator III, the magnetically sensitive rotary body 5 starts to rotate, and the sealing valve 2 is lifted upwards, so that urine is rapidly discharged from the urine outlet 7 of the urethra pump I under the action of the drainage blade 4 and the bladder pressure;
5) Turning off the control switch 11 of the hand-held activator III, when the urethral pump I senses the turning-off signal of the hand-held activator III, the magnetically sensitive rotating body 5 stops rotating, the sealing valve 2 is turned off downward,
Urination is stopped.
The invention has the following points:
Urine is sucked into the empty bladder and prevented from flowing out when urination is not desired.
The physician selects the appropriate size for the patient based on the size and performs the initial instrument insertion.
After training, the insertion and removal of the instrument can be performed by the patient or carer, each insertion element can be used for 29 days, and when the urethral pump I is placed in the urethra for 29 days, it can be pulled out directly by the doctor.
The residual urine volume after evacuation is greatly reduced in 98% of the patients using the device.
The occurrence of asymptomatic bacterial urine, urinary tract infections, bladder inflammation, genitalia and urinary (genital) pain, hematuria, urinary leakage, urinary frequency, urgency, bladder spasticity, vulva, vagina and urinary tract diseases resulting from urinary catheter insertion is greatly reduced.
Female patients using the device can urinate normally without urine guiding or urine drainage bags every day, so that the autonomy of the patients is greatly improved. The likelihood of urethral or bladder injury associated with repeated insertions is reduced. Solves the problems of extremely uncomfortable feeling of patients caused by frequent use of the catheter and large-area infection generated by the common catheter, and has convenient use and extremely low infection rate
