20230147389 · 2023-05-11 ·

A system that transdermally delivers a drug to a patent can be used to reduce suffering from acute/chronical musculoskeletal pain. The system includes a backing layer, an adhesive layer, a topical applicator, a suitable quantity of drug, and a quantity of topical carrier. The topical applicator is connected across and against the backing layer by the adhesive layer. The suitable quantity of drug and the quantity of topical carrier are homogenously mixed together as a topical medication, which is retained and dispensed from the topical applicator. The topical applicator includes a flat applicator body, a plurality of blunted spikes, and a containment rim. The flat applicator body is the structural base of the topical applicator. The containment rim is used to perimetrically confine the topical medication. The blunted spikes are used to increase the surface area of the topical applicator in order to improve its retention of the topical medication.

Pressure-sensitive adhesive sheet, adhesive bandage, and method of producing the same

A pressure-sensitive adhesive sheet including a pressure-sensitive adhesive layer is provided. The pressure-sensitive adhesive layer includes crater portions, each crater portion being concavely formed on an adhesive surface of the pressure-sensitive adhesive layer. A surface of the crater portion has a plurality of through holes.

Medical tape using a film-forming base portion and method for manufacturing the same
11642434 · 2023-05-09 ·

A method for manufacturing a medical tape includes: applying a solution polymer serving as an elastic base member portion having an elastic function to an upper layer of a film forming base portion having an inelastic function to form a film of the solution polymer; laminating an adhesion portion having a function to apply and hold the elastic base member portion to a skin on an upper layer of the elastic base member portion, and laminating a release portion having a function to protect the adhesion portion on an upper layer of the adhesion portion; peeling and removing the film forming base portion from the elastic base member portion to obtain the elastic base member portion in a state where a residual shrink force generated by a forming shrinkage of the solution polymer is reduced and to obtain a three-layer structure consisting of the elastic base member portion.

Wound dressing
09844475 · 2017-12-19 · ·

A method and apparatus are disclosed for dressing a wound. The apparatus comprises a sealing layer comprising at least one orifice, an absorbent layer over the sealing layer, absorbing wound exude and a liquid impermeable, gas permeable filter layer over the absorbent layer.

METHOD OF DETECTING DETACHMENT OF AN OSTOMY DEVICE FROM A PATIENT
20170340474 · 2017-11-30 ·

A method of detecting detachment of an ostomy device from a patient includes providing, in the ostomy device, a first electrode separated from the patient by an adhesive that attaches the ostomy device to the patient, where a first capacitor is formed between the first electrode and the patient. The method includes applying a signal to an electrical circuit that includes the first capacitor, and detecting changes in a capacitance value of the first capacitor based on frequency responses of the electrical circuit to the signal. The method additionally includes activating an alarm based upon detecting the changes in the capacitance value of the first capacitor.

Foldable IV catheter securement dressing for protecting against inadvertent contamination

Sterile intravenous catheter securements and securement dressings that provide simpler, more effective, and lower risk intravenous catheter placement and securement in a patient are described. Catheter securement dressings may include one or more adhesive portions positioned and configured to maintain a position of a catheter assembly following catheterization. Catheter securement dressings may be secured to a patient with an adhesive portion, and the catheter assembly may then be placed into the patient through an access opening in the catheter securement dressing. Portions of catheter securement dressings may then by folded over and adhered to each other and portions of the catheter assembly to secure the catheter assembly to the patient.

Antimicrobially active wound dressing for catheter fixings
09827397 · 2017-11-28 · ·

A multilayered wound dressing which is two-dimensional and has a peripheral edge is provided that includes at least one hydrophobic antimicrobial layer, at least one absorbent layer which includes a water-containing hydrogel, and a covering layer. Starting from the edge of the wound dressing, at least one incision is formed, which partially separates the wound dressing.

Ostomy monitoring system and method

An ostomy bag can include one or more sensors for measuring one or more metrics. An ostomy wafer can also include one or more sensors for measuring one or more metrics. The sensors can be temperature sensors and/or capacitive sensors, for example, and the metrics can include bag fill, leakage, skin irritation, and phase of stoma output, among others.

REDUCED PRESSURE APPARATUS AND METHODS

Some embodiments have a pump assembly mounted to or supported by a dressing for reduced pressure wound therapy. The dressing can have visual pressure, saturation, and/or temperature sensors to provide a visual indication of the level of pressure, saturation, and/or temperature within the dressing. Additionally, the pump assembly can have a pressure sensor in communication with the flow pathway through the pump, and at least one switch or button supported by the housing, the at least one switch or button being accessible to a user and being in communication with the controller. The pump assembly can have a controller supported within or by the housing, the controller being configured to control an operation of the pump. The pump can be configured to be sterilized following the assembly of the pump such that all of the components of the pump have been sterilized.
