The technical field is as follows:
a reusable urethral catheterization device consists of a conical urethral catheter, a flat-mouth urethral catheterization bag, a buffering urethral bag and a drainage bag, and is a medical instrument used for collecting urine outside a male adult urinary incontinence patient body and avoiding urine leakage.
(II) background technology:
the senile urinary incontinence is a common disease, in particular to male patients with prostatic hyperplasia and urinary incontinence, patients with limited activities after operation and urinary incontinence, and male patients who have paraplegia and long-term bedridden life and cannot take care of self-collection of urine in vitro. Generally, urine is collected in vitro by using a diaper, a diaper pad, a closed urine collection bag, an intelligent urine guide bag, a urine guide sleeve, a urine collection bag and the like as urine collection appliances, so that urine leakage and bed wetting are avoided. Most of the devices adopt a closed urine receiving mode, and other devices adopt a silica gel urethral catheterization sleeve mode, the volume of a urine collecting bag is 1000ml to 3000ml, the price is high, each urine collecting bag is several yuan to dozens of yuan, the urine collecting bag is mostly disposable, urine leakage still occurs in use sometimes, and some products for lying and standing are also distinguished.
The urine collection in vitro basically adopts a urine non-wetting or closed urine receiving mode, and because the external genitalia of a patient is eroded and stimulated by the urine for a long time, inflammation, pruritus, local skin diaper rash and ulceration and even bedsore are easily caused. This is because urine erodes the skin over a long period of time, making the stratum corneum of the skin soft and losing its normal defense ability, and the above symptoms such as itching, rash, bedsores, etc. are easily caused by the stimulation of the skin by ammonia in urine.
In another mode of urine reception by a urine sleeve, a medical silica gel urine guide sleeve is sleeved on a penis like a condom and tightly wrapped by the elasticity of the urine sleeve to prevent urine leakage, so that after operation, particularly after prostate operation, the external genitalia of a patient often has swelling or inflammation and urethral pain, and symptoms are aggravated if the patient is pressed by the silica gel urine guide sleeve. Even if the external genitalia has no swelling or inflammation, the size of the penis can be changed along with the change of the surrounding environment, the temperature and the like of the physiological condition of a person, and the silica gel urethral catheterization sleeve cannot adapt to the change, so that the phenomena of urine leakage or slippage of the urethral sleeve to pollute bedding and the like are easy to occur.
