Definitions

  • the present invention relates to a reusable intermittent self urinary catheter that a patient can use by herself.
  • One way to prevent these complications is that when a patient with difficulty in urinating the bladder, such as a patient with dysuria, has urged to urinate, the catheter is inserted from the urethra to the bladder and the urine in the bladder is removed. Treatment (self-urination) that is guided out of the body and discharged is performed.
  • this self-conduction urine is intermittently used by the patient using the silicone rubber catheter several times a day. This is a method for preventing the bladder and kidneys from deteriorating by inserting a catheter into the urine and taking out the remaining urine in the bladder, and its effectiveness is generally well known.
  • the catheter since the catheter is inserted only during urination, the catheter is not necessary except during urination, and the burden on the daily life of the patient is small, which is also a useful treatment for the patient to lead a comfortable life.
  • the current Japanese urinary feeding method in Japan is often performed by repeatedly using a catheter using silicone rubber, which is a safe material for the body. After urinating using a catheter, it is common to wash the used catheter with tap water and immerse it in a disinfectant solution (for example, 0.025% benzalkonium chloride aqueous solution) for storage. It is.

  • a catheter used for self-urination is generally used repeatedly several times and needs to be cleaned each time. Therefore, when a urinary hole is provided on the side surface on the distal end side of the catheter, There is a problem that the tap water flow is stopped by the tip closed when the tap water for cleaning the catheter passes through the lumen of the catheter, and the cleaning takes time. Further, the closed tip becomes a dead space, and dirt is easily accumulated in the dead space.
  • the present invention has been made in view of the above problems, and an object of the present invention is to provide an intermittent self urinary catheter that can be easily washed with a short washing time.
  • An intermittent self urinary catheter according to another aspect of the present invention is formed such that the urinary hole opens in the insertion direction of the urinary catheter.

  • the distal end of the urinary catheter 10 is tapered so that it can be easily inserted into the urethra. It is preferable that the inner diameter of the urinary hole 13 is formed to be the same size as the inner diameter of the lumen 14. As a result, the frictional resistance applied to the urine by the inner wall of the urinary catheter 10 when the urine flows through the lumen 14 can be reduced.
  • the cap 20 includes a holder 24 that is detachably engaged with an opening of a disinfecting liquid case 30 that stores a disinfecting liquid, and a cap portion 21 for sealing the urine outlet 12 of the urinary catheter 10. It is formed in a substantially circular shape as viewed.

That is, as compared with a conventional catheter having a urinary hole provided only on the side surface, the insertion depth of the catheter can be reduced, and damage to the bladder wall due to insertion (contact) of the catheter can be prevented. it can. Furthermore, since the urinary tract 13 is formed at the tip 11, the direction of urine movement when introduced from the bladder into the urinary tract 13 is substantially linear and the resistance is reduced, so that urine is discharged from the bladder.

Further, since the urinary hole 13 is formed at the distal end 11, there is no dead space as in the prior art, dirt is not easily accumulated in the urinary catheter 10, and the antiseptic solution is filled in the lumen of the urinary catheter 10.
