Abstract
The invention discloses an automatic-urine-discharging prostate supporting catheter. The automatic-urine-discharging prostate supporting catheter comprises an indwelling tube and at least two bag bodies, wherein a hollow urine discharging channel is formed in the indwelling tube, and the bag bodies are filled with media to expand and can be attached to the neck of the bladder after expanding. The bag bodies are arranged on the outer wall of the indwelling tube in the circumferential direction of the indwelling tube. A gap wall is formed between the outer wall of the indwelling tube and each adjacent bag body, and a urine discharging opening communicated with the hollow urine discharging channel of the indwelling tube is formed in at least one gap wall. By means of the automatic-urine-discharging prostate supporting catheter, the foreign body sensation caused when the automatic-urine-discharging prostate supporting catheter is located in the bladder can be alleviated, the discomfort degree of a patient in the bladder is reduced, the incomplete urination sensation of the patient is avoided, and therefore urination of the prostate patient is facilitated.
Description
Technical field
The present invention relates to one can automatic micturition prostate supporting tube, belongs to technical field of medical instruments.
Background technology
At present, male prostatic hyperplasia, the prostatic urethra sickness rate that is obstructed is caused to account for 20%-30%, particularly its morbidity amount increases thereupon with advancing age, this urethra disease initial stage of being obstructed all treats by taking medicine, but take medicine and finally cannot effect a radical cure, all must carry out other partner treatments such as operation to alleviate, (as micro-wave therapeutic after particularly carrying out naturopathy to prostatosis etc., radio-frequency (RF) therapy, laser therapy, electric cutting treatment etc.) cause prostatic edema to make urethral stricture produce dysuria, urinary retention is caused time serious, common solution inserts drainage tube drain to patient.Urethra is inserted in traditional drainage tube one end, puts into intravesical, and the other end is placed on that penis is outer to be connected with drainage bag, because drainage tube directly passes through sphincter of urethra, makes sphincter not recur to draw together and about act on, so can only urinate by straight-line.The drainage technology of this drainage tube, its shortcoming is: patient can not automatic micturition, as long as bladder has urine just directly to enter in drainage bag; Plug-in drainage bag, patient can be very painful, very inconvenient to its action; In addition, this indwelling catheter is the treatment of a kind of invasive, not only can cause urethrovesical mucosa injury, for the infection of growing of antibacterial opens door, also may cause the infection (bibliographical information) of urinary tract simultaneously, if this drainage tube indwelling more than 5 days person's bacteriuria sickness rate are 100%, a kind of prostate supporting tube is there is in prior art, but it is placed in urethra, obvious foreign body sensation can be caused to patient, cause the sense of discomfort of patient's bladder, make patient have the sensation of urine retention, be unfavorable for urinating.
Summary of the invention
Technical problem to be solved by this invention is the defect overcoming prior art, there is provided one can automatic micturition prostate supporting tube, it can not only reduce it at intravesical foreign body sensation, and reduce the immoderation of patient's bladder, avoid the phenomenon that patient produces urine retention sensation, thus prostate patient is beneficial to and urinates.
