Abstract
The present invention is a catheter assembly allowing for non-contaminated insertion of a catheter into a urinary canal. The assembly includes a package for the catheter and an applicator to be used for guiding the catheter into the urinary canal without touching the catheter by holding the catheter via walls of the applicator. The assembly further comprises clamping means for pressing the walls of the applicator into engagement with the catheter. The present invention further relates to an applicator with integrated clamping means to be used with the assembly.
Claims15
An applicator for non-contaminating application of a medical utensil, said applicator comprising:
- a tubular compartment with a first open end, the compartment being adapted to receive at least a part of an utensil and being formed with a wall having an inner surface facing the utensil and an outer surface, the wall being provided with a flexible zone so as to allow the inner surface of the wall to be squeezed into engagement with the utensil upon a pressure applied to the outer surface of the wall;
- a clamping element including a first handle member joined to the applicator and being arranged to move between a first position in which said handle member applies pressure to the utensil arranged in the compartment by movement of said handle member toward said outer surface and a second at rest position in which the pressure is released, said handle member arranged to avoid engagement with other parts of the applicator so that movement between said first and second positions is unhindered;
- and
- a second handle member joined to the applicator and arranged to move between a first position in which said second handle member applies pressure to the utensil arranged in the compartment by movement of said handle member toward said outer surface and a second position in which the pressure is released, said second handle member being separated from the first handle member such that, during movement thereof and in both said first and second positions, said first and second handle members remain free of engagement with one another.
1 more element
The combination of a urinary catheter and an applicator for non-contaminating application of said catheter, said combination comprising:
- a urinary catheter having an end to be inserted into a patient's urinary canal for drainage of urine;
- and
- an applicator including a tubular compartment and a clamping element, said compartment having a first open end to receive at least a part of said catheter within said compartment and being formed with a wall having an inner surface facing said catheter and an outer surface, the wall having a flexible zone so as to allow the inner surface of the wall to be squeezed into engagement with the catheter within said compartment upon a pressure applied to the outer surface of the wall;
- and
- said clamping element including a handle with a first handle member and a second handle member, said first handle member being arranged to move between a first position in which said handle member applies pressure to said catheter within the compartment by movement of said handle member toward said outer surface and a second position in which the pressure is released, said handle member arranged to avoid engagement with other parts of the applicator so that movement between said first and second positions is unhindered;
- said second handle member being arranged to move between a first position in which said second handle member applies pressure to said catheter within the compartment by movement of said handle member toward said outer surface and a second at rest position in which the pressure is released, said second handle member being separated from said first handle member such that, during movement thereof and in both said first and second positions, said first and second handle members remain free of engagement with one another;
- and
- said catheter being inserted into said patient urinary canal by bringing the wall of said compartment into contact with said catheter insertable end and gripping said catheter within said compartment while introducing a tip of said catheter into said urinary canal, releasing the grip and thereby allowing the handle to return to said second position, shifting the applicator to a new position along the catheter, returning said handle to said first position to grip a next section of said catheter, and guiding the catheter further into said urinary canal until urine starts to drain through said catheter.
