Catheter assembly
A catheter assembly includes a first tubular section and a second tubular section. The first section provides a urinary catheter that is disposed in the second section. The second section has a proximal end with a first opening and a distal end with a second opening. The first opening is adapted for dispensing a proximal end of the urinary catheter out of the proximal end of the second section and the second opening is provided to drain liquid from the urinary catheter through and out of the second section. A sealing obstruction is formed between an inner surface of the second section and an outer surface of the urinary catheter. The sealing obstruction is adapted to form a seal between the distal end portion of the urinary catheter and the proximal end of the second section.
1. A catheter assembly comprising:
a first tubular section providing a urinary catheter having a proximal end that is insertable into a bladder and an opposing distal end portion;
a second tubular section, with the first tubular section disposed in the second tubular section, the second tubular section having a proximal end with a first opening and a distal end with a second opening, the first opening is adapted for dispensing the proximal end of the urinary catheter out of the proximal end of the second tubular section and the second opening is provided to drain liquid from the urinary catheter through and out of the second tubular section;
a plug connected to the distal end portion of the first tubular section, the plug configured to seal the second opening in the second tubular section when the first tubular section is disposed in the second tubular section; and
a sealing obstruction formed on an inner surface of the second tubular section;
wherein the sealing obstruction is adapted to engage with a groove formed in the plug to form a seal between the distal end portion of the urinary catheter and the proximal end of the second tubular section when the proximal end of the urinary catheter is exposed a sufficient length for insertion into the bladder.
2. The catheter assembly of claim 1 , wherein the proximal end of the second tubular section further comprises a detachable closure.
3. The catheter assembly of claim 1 , wherein the sealing obstruction is a radial protrusion formed on the inner surface of the second tubular section.
4. The catheter assembly of claim 1 , wherein the sealing obstruction is a ring-shaped member arranged formed on the inner surface of the second tubular section.
5. The catheter assembly of claim 1 , wherein the urinary catheter is a hydrophilic catheter including a lubricant and the second tubular section contains a water solution.
6. The catheter assembly of claim 1 , wherein the second tubular section contains a liquid swelling medium adapted to lubricate the urinary catheter.
7. The catheter assembly of claim 1 , wherein the urinary catheter is sized such that, when the proximal end of the urinary catheter is exposed to the sufficient length, the urinary catheter is sized for insertion into the bladder of a female.
8. The catheter assembly of claim 1 , wherein the urinary catheter is sized such that, when the proximal end of the urinary catheter is exposed to the sufficient length, the urinary catheter is sized for insertion into the bladder of a male.
