Internal and external double-capsule prostate hemostasis catheter

Abstract

The invention relates to the technical field of prostate medical instruments, in particular to an internal and external double-capsule prostate hemostasis catheter. The catheter comprises a main catheter, an inner capsule, an outer capsule, an inner capsule cavity, an outer capsule cavity and a drainage cavity and a washing chamber disposed in the main catheter, the inner capsule and the outer capsule are wrapped outside the main catheter, the inner capsule is disposed at an inner front end of the outer capsule, an inner capsule outlet and an outer capsule outlet are formed in the main catheter, the inner capsule outlet and the outer capsule outlet are respectively disposed in the inner capsule and the outer capsule, an inner capsule injection port, an outer capsule injection port, a drainage chamber outlet and a water chamber inlet are formed in one end of the main catheter, a drainage chamber inlet and a washing chamber outlet are formed in the end portion of the other end, near theinner capsule, of the main catheter, the inner capsule is filled with water or inflated to expand and block the bladder, which can stop bleeding and prevent the blood from flowing into the bladder, inaddition, the outer capsule can be inflated or injected with the water, wounds on the prostate are blocked, and the effect of stopping bleeding is achieved.

Description

technical field [0001] The invention relates to the technical field of prostate medical equipment, in particular to a hemostatic catheter for prostate with inner and outer double capsules. Background technique [0002] The current common urinary catheters all have only one function of catheterization. For some patients who need timely hemostasis and catheterization after the prostatic hyperplasia resection, they can only use other instruments or take other measures to stop the bleeding, thereby reducing the use effect of the catheter. In addition, after surgery, such as prostate resection or laser surgery, the wound will bleed, and the blood will easily flow into the bladder and cause bladder filling, which will affect the treatment. In the prior art, the urinary catheter with upper and lower independent balloons already has a certain hemostatic function, but because the two independent balloons cannot completely seal the bladder neck, the hemostatic effect is not good, and...

Problems solved by technology

For some patients who need timely hemostasis and catheterization after undergoing prostatic hyperplasia surgery, they can only use other devices or take other measures to stop bleeding, thus reducing the use effect of the catheter

In addition, after surgery, such as prostate resection or laser surgery, the wound will bleed, and the blood will easily flow into the bladder, causing bladder tamponade, which will affect the treatment

In the prior art, the urinary catheter with upper and lower independent balloons already has a certain hemostatic function, but because the two independent balloons cannot completely seal the bladder neck, the hemostatic effect is not good, and there are still deficiencies in hemostasis
