The retention device is configured to be coupled to the end outer part of a urinary catheter or feeding catheter of the type having a “T” shaped valve, the retention device comprising a body with: a first portion extending in a longitudinal direction “X” and having an inner recess for receiving and accommodating an end part of a urinary catheter or feeding tube where the first portion is closed above by an upper portion comprising an anti-leakage element of the open end of the catheter or tube connecting the catheter, a second portion extending in a second direction “Y”, transverse to the longitudinal direction “X”, wherein the second portion comprises an inner recess extending along the transverse direction “Y”, and wherein the second portion is open at one of its ends, while at the opposite end it comprises an anti-opening wall, and a fastening element, configured to releasably fasten the retention device to an element external to the user's body.

This allows the user to perform any type of sports activity with the catheter fitted and placed inside the support without any risk of accidental action.

The invention also concerns the assembly formed by this retention device and a catheter.

Disclosed are embodiments of a method for affecting thrombi formation on an indwelling catheter. The method involves the step of providing an intravenous catheter. The intravenous catheter includes an inner surface and an outer surface, and the intravenous catheter is located within a blood vessel. A light diffusing element is inserted into the intravenous catheter. Light is emitted from the light diffusing element such that the light irradiates the intravenous catheter. The light emitted from the light diffusing element is configured to promote or hinder thrombi formation on the inner surface or outer surface of the intravenous catheter. Also disclosed are an illumination system for affecting thrombi formation on an intravenous catheter as well as an indwelling intravenous catheter system.

The present invention relates to a novel catheter brush device. The device is designed to offer a more effective method of removing blood clots and debris from the bladder without requiring additional surgery. The device comprises a brush with a blunt end with soft bristles, as well as a loop end that acts as a handle. Users remove the drainage tube from the catheter and insert the brush through the opening to the tip of the catheter. The brush is then moved in a gentle, circular motion to clear any clotting and blockages from the catheter. The brush is then removed, and the drainage tube reattached, such that urine can flow freely through the catheter. If sterility is maintained, process may be repeated as needed.

The subject invention provides materials methods for reducing infections in subjects. The materials methods utilize chlorhexidine, which has been found to be surprisingly non-toxic. The lack of toxicity facilitates the use of chlorhexidine in contexts that were not previously thought to be possible.

Antibacterial coatings and methods of making the antibacterial coatings are described herein. A first branched polyethylenimine (BPEI) layer is formed and a first glyoxal layer is formed on a surface of the BPEI layer. The first BPEI layer and the first glyoxal layer are cured to form a crosslinked BPEI coating. The first BPEI layer can be modified with superhydrophobic moieties, superhydrophilic moieties, or negatively charged moieties to increase the antifouling characteristics of the coating. The first BPEI layer can be modified with contact-killing bactericidal moieties to increase the bactericidal characteristics of the coating.

A urine collection system is provided for use on a patient support apparatus. The urine collection system comprises a housing and a container for mounting to the housing in a releasable manner.

Urinary catheter-insertion kits can include a working tray, a storage tray, a protective paperboard, and a urinary catheter assembly, including a urinary catheter and a drainage system. The working tray can be nested on top of the storage tray. The working tray includes preformed sections configured to accommodate components of the urinary catheter-insertion kit. Methods of urinary catheterization include use of the urinary catheter-insertion kits.

A protective sleeve for a urinary catheter includes a sleeve configured to extend over an outer surface of the urinary catheter shaft from a proximal insertion end of the catheter shaft to a distal end of the catheter shaft. The protective sleeve includes a protective sleeve tip defining the proximal end portion of the sleeve. The sleeve and the protective sleeve tip are of a single unitary construction and the sleeve and protective sleeve tip are formed of the same thin, flexible film. The protective sleeve tips has a first pre-use configuration when a proximal insertion end of the catheter is not within the protective sleeve tip wherein the protective sleeve tip is in a collapsed state, and a second configuration when a proximal insertion end of a urinary catheter is inserted into the protective sleeve tip, in the second configuration the protective sleeve tip being in an extended state that is configured to cover the proximal insertion end of the urinary catheter shaft and the thin, flexible film conforms to and is supported by the proximal insertion end of the urinary catheter for insertion of the protective sleeve tip into the urethral opening.

In some examples, a device includes a catheter insert elongated body defining a body lumen, the catheter insert elongated body being configured to be at least partially inserted to a catheter lumen defined by a catheter without covering a first fluid opening of the catheter and to form a fluidically tight coupling with the catheter, and one or more sensors positioned on the elongated body. At least one of the one or more sensors are configured to sense a substance of interest. The catheter insert elongated body includes a material that is a substantially non-permeable to the substance of interest.

Disclosed is a catheter device including a proximal tube having a first part of a first lumen; a distal tube having a second part of the first lumen; a second lumen connecting the proximal tube and the distal tube; wherein the connection comprise an area of discontinuity between the first part and second part; wherein the area of discontinuity comprises a support element configured to resist axial movement of the distal tube relative to the proximal tube and vice versa; and wherein the second lumen is arranged to activate or cause at least one obstruction element to restrict the flow of urine from the proximal tube to the area of discontinuity and to restrict the flow of urine from the area of discontinuity to the distal tube.
