Description

Adult male urinary catheter capable of relieving irritation symptom and reducing occurrence of urinary tract infection

Technical Field

The utility model relates to the technical field of catheters, in particular to a catheter capable of relieving bladder irritation symptoms of adult male patients.

Background

A urinary catheter is a tube that is inserted into the bladder from the urethra to drain urine. Is a pipeline made of natural rubber, silicon rubber or polyvinyl chloride (PVC), can be inserted into the bladder through the urethra so as to drain urine, and after the catheter is inserted into the bladder, an air bag is arranged near the head end of the catheter to fix the catheter and is left in the bladder, so that the catheter is not easy to fall out, and the drainage tube is connected with a urine bag to collect urine.

However, the existing urinary catheters have certain defects:

1. when the existing catheter is inserted into the bladder of a patient, the balloon can not shield the part of the catheter entering the bladder, and the head end of the catheter can be contacted with the inner side of the bladder of the patient, so that the bladder of the patient is stimulated, urinary tract stimulation symptoms such as frequent urination and urgent urination pain are generated, and particularly, the patient with the catheter left for a long time can not tolerate the urinary tract stimulation symptoms; in the case of prostate and bladder operation patients, bladder spasticity is often induced due to the stimulation of the indwelling catheter, which induces postoperative bleeding and bladder clot tamponade.

2. After the urinary catheter is left, the urinary catheter is completely wrapped by the urinary lumen of an adult male, so that liquid secreted by the urinary lumen, the bulbar gland of the urinary tract and the parathyroid gland of the urinary tract and the fallen epithelial cells can not be flushed out of the body, the self-cleaning function and the immune function in the urinary tract are weakened, and urinary tract infection such as urethritis, prostatitis and epididymitis can easily occur to patients.

Disclosure of Invention

The utility model provides an adult male urinary catheter capable of relieving bladder irritation symptoms of a patient, which has the advantages of avoiding the urinary catheter from irritating the bladder of the patient, draining fluid secreted by a urethral cavity, a bulbar gland and a paraurethral gland and shedding epithelial cells, effectively reducing urinary tract infection and solving the problems in the background technology.

In order to achieve the above purpose, the present utility model provides the following technical solutions:

can relieve bladder irritation symptoms of patients and reduce incidence rate of urinary tract infection after indwelling the urinary catheter.

The urine drainage catheter comprises a catheter body, wherein one end of the catheter body is the front end of the catheter, a drainage hole is formed in the front end of the catheter, a water injection end and a urine drainage end are arranged at the other end of the catheter body, and the drainage hole is communicated with the urine drainage end through a drainage channel to drain urine out of the body; the catheter is characterized in that an air bag is arranged on the outer side of the head end of the catheter body, the air bag is annular, and the air bag is communicated with the water injection end through a water injection channel. The catheter can alleviate bladder irritation symptoms of a patient, the catheter passes through the male urinary bladder, the front end of the catheter is placed into the bladder inner side of the patient, water is injected into the bladder inner side of the bladder through the water injection end and the water injection channel, so that the bladder is inflated, the inflated bladder (15 ml) can prevent the whole device from separating from the bladder inner side of the patient, and meanwhile, the bladder surrounds the outer side of the front end of the catheter, so that the front end of the catheter is completely prevented from being contacted with the bladder of the patient, and bladder irritation symptoms such as frequent urination, urgent urination and painful urination are prevented from being induced, and the effect of improving the comfort of the device is achieved.

In addition, the catheter body is equipped with 6 spiral distribution drainage side openings from the outer surface below the water pocket bottom, communicates with each other with the drainage passageway to drainage urethra endocrine, discharges outside the body through the urination end, can effectively reduce adult male sex and keep somewhere the urinary tract infection incidence behind the catheter. Because the distribution of the drainage side holes is only 6cm long, and the male urethra is about 16cm long, the catheter can ensure that the lowest drainage side hole cannot be exposed out of the body, so that side leakage cannot occur.

The catheter body has been seted up a plurality of drainage side opening on the surface. The number of the drainage side holes is six, and the six drainage side holes are distributed on the outer side of the catheter body in a 120-degree threaded mode and are positioned below the bottom of the water sac. The drainage holes are distributed from the lower part of the bottom of the catheter water sac to the distal end, the distance is 6cm, 1 drainage side hole is arranged at each 1cm interval, the total number of the drainage side holes is 6, and the drainage side holes are spirally distributed in a 120-degree rotation mode. The drainage side hole is communicated with the urination end through a drainage channel so as to drain the liquid secreted by the urethral cavity, the bulbar gland and the paraurethral gland and the exfoliated epithelial cells. Because the drainage side holes are distributed only 6cm long, and the male urethra is about 16cm long, the catheter can ensure that the lowest drainage side hole cannot be exposed out of the body, so that side leakage cannot occur.

The utility model has the following beneficial effects:

1. can alleviate the catheter of adult male patient's bladder irritation symptom, through setting up the position at the catheter front end with the gasbag, can extend the catheter front end to patient's bladder inboard, inject water to the inboard of gasbag through water injection end and water injection passageway for the gasbag inflation, the gasbag (15 ml) of inflation can avoid whole device to break away from patient's bladder inboard, and the gasbag surrounds the outside at the catheter front end simultaneously, can avoid catheter front end and patient's bladder contact completely, in order to reduce bladder irritation and uncomfortable sense, thereby reach the effect of promoting device travelling comfort.

2. According to the catheter capable of relieving bladder irritation symptoms of adult patients, six spiral-shaped drainage side holes are formed below the bottom of the water sac of the catheter body, so that liquid secreted by the urethral cavity, the bulbar glands of the urethra and the parathyroid glands of the urethra and fallen epithelial cells can be discharged through the drainage channels through the drainage side holes in the long-term indwelling catheter process, and urinary tract infection such as urethritis, epididymitis and prostatitis can be reduced. Because the distribution of the drainage side holes is only 6cm long, and the male urethra is about 16cm long, the catheter can ensure that the lowest drainage side hole cannot be exposed out of the body, so that side leakage cannot occur.
