Abstract
A reusable urinary catheter kit that has a container that has a urinary catheter and a medium. The reusable urinary catheter kit also has at least one chlorine-containing species. The container of the reusable urinary catheter kit is resealable. Further, the catheter in the reusable urinary catheter kit is an intermittent urinary catheter.
Claims29
A reusable urinary catheter kit comprising a container comprising:
- a urinary catheter;
- and a medium comprising at least one chlorine-containing species, wherein the container is resealable.
A reusable urinary catheter kit as claimed in any preceding claim, wherein the catheter further comprises at least one additive, preferably at least one amphiphilic additive, wherein the amphiphilic additive is preferably polymeric or oligomeric.
A reusable urinary catheter kit as claimed in any preceding claim, wherein the catheter comprises a hollow polymeric tubular body comprising a base polymer that is independently chosen from:
- polyolefins, polyesters, polyacrylates, polyamides, thermoplastic elastomeric material, polyether block amide, thermoplastic vulcanizates, thermoplastic copolyesters, thermoplastic polyamides, fluororubber, water disintegrable or enzymatically hydrolysable material, and combinations, blends or copolymers of any of the above materials, and wherein the base polymer preferably comprises a polymer independently chosen from:
- polyolefins, polyvinyl chloride, polyurethane, styrene-butadiene copolymer (SBC), styrene-ethylene-butylene-styrene copolymer (SEBS), thermoplastic elastomeric material, and combinations, blends or copolymers of any of the above materials.
A reusable urinary catheter kit as claimed in any preceding claim, wherein the medium comprises at least one chlorine-containing species that is independently chosen from:
- hypochlorous acid, at least one hypochlorite salt, chlorine dioxide, molecular chlorine, a dichloroisocyanurate salt, chloroazodin, dichlorodimethylhydantoin, chloroxylenol, chlorhexidine, and combinations thereof.
A reusable urinary catheter kit as claimed in any preceding claim, wherein the medium comprises the at least one chlorine-containing species in a total concentration of between 0.005-0.6 wt. % of the medium.
A reusable urinary catheter kit as claimed in any preceding claim, wherein the medium comprises at least one alkali metal halide salt, preferably comprising sodium chloride, and preferably sodium chloride and at least one of:
- hypochlorous acid and a hypochlorite salt.
A reusable urinary catheter kit as claimed in any preceding claim, wherein the medium comprises a base, preferably sodium hydroxide, and the medium preferably comprises at least one base, preferably comprising sodium hydroxide and at least one of:
- hypochlorous acid and a hypochlorite salt.
A reusable urinary catheter kit as claimed in any preceding claim, wherein the medium is present as a solution, preferably an aqueous solution.
A reusable urinary catheter kit as claimed in any preceding claim, wherein the medium is present as a liquid having a viscosity of between 0.5-5000 cP.
A reusable urinary catheter kit as claimed in any preceding claim, wherein the medium has a pH of between 2 and 14.
A reusable urinary catheter kit as claimed in any preceding claim, wherein the medium is in direct contact with the catheter, preferably with at least one surface thereof, and wherein the catheter is preferably submerged in the medium.
A reusable urinary catheter kit as claimed in any preceding claim, wherein the medium is contained in a separate container that is located in the container and is not in direct contact with the catheter, and wherein the separate container is preferably rupturable or pierceable, in use, to release the contained medium from the separate container and into direct contact with the catheter.
A method of sterilising and/or lubricating a reusable urinary catheter, the method comprising the steps of:
- a. Providing a resealable container in its sealed configuration, said container comprising a urinary catheter, and further providing a medium comprising at least one chlorine-containing species;
- b. Unsealing the container;
- c. Removing the urinary catheter from the unsealed container;
- d. Performing catheterisation with the catheter;
- e. Reinserting the catheter into the container and contacting the catheter with the medium comprising at least one chlorine-containing species in the container;
- and
- f. Resealing the container.
