Abstract
Urine collection bags are provided that include features that facilitate easy insertion of a urinary catheter into a patient's bladder. In some implementations, the urine collection bag is formed of a soft, flexible material that is comfortable when it contacts the user's skin, easy to manipulate, and relatively noiseless during use.
Claims24
A urine collection bag for use in a urinary catheter system, comprising:
- opposed portions of plastic sheet material that are sealed together around a peripheral edge to define a substantially closed receptacle;
- at least one of the portions including a surface texture having a depth sufficient to increase the flexibility of the plastic sheet material relative to an otherwise identical plastic sheet material without the surface texture, the surface texture being disposed on an interior surface of the receptacle;
- and
- an interface tube having a beveled opening constructed to allow a user to apply pressure with an index finger or thumb from an exterior surface of the receptacle and thereby press the surface texture against a urinary catheter disposed within the receptacle to hold the catheter in place while manipulating the sheet material to advance the catheter out of the receptacle.
A urine collection bag for use in a urinary catheter system, comprising:
- opposed portions of plastic sheet material that are sealed together around a peripheral edge to define a substantially closed bag;
- and
- a surface texture disposed on at least one of the opposed surfaces of the portions,
- wherein the surface texture is constructed to increase the friction between the opposed surfaces of the portions and a catheter during gripping of the catheter by a patient, relative to the friction exerted by opposed portions of an otherwise identical plastic sheet material without the surface texture.
A closed catheter system comprising:
- a urine collection bag including opposed portions of plastic sheet material that are sealed together around a peripheral edge to define a substantially closed bag;
- a surface texture disposed on the at least one of the opposed surfaces of the portions;
- and
- a catheter disposed within the bag;
- wherein the urine collection bag is constructed to allow the catheter to be advanced from the bag by a user, and wherein the surface texture is constructed to increase the friction between the opposed surfaces of the portions and the catheter during gripping of the catheter by a patient, relative to the friction exerted by opposed portions of an otherwise identical plastic sheet material without the surface texture.
