MEDICAL DRESSING PATCH AND MANUFACTURING METHOD THEREOF
20220183898 · 2022-06-16 ·

The present invention relates to a medical dressing and a manufacturing method, and to a medical dressing and a manufacturing method therefor, the medical dressing comprising: a lower support film; a release film; and an adhesive sheet part (110) for application, which is placed on the release film (200) and is attached to the skin, wherein the release film (200) consists of a release film part (210) for fixing and a separable release film part (220) to be separated therefrom by a cutting line (211) formed on the release film part (210) for fixing, so that a predetermined region of the separable release film part is positioned to overlap with the bottom surface of the adhesive sheet part (110), thereby allowing, during separation of the separable release film part (220) from the release film part (210) for fixing, separation together with the adhesive sheet part (110) for application, and the area of the separable release film part (220), which overlaps with the bottom surface of the adhesive sheet part (110), is relatively smaller than the area of the separable release film part, which does not overlap with the adhesive sheet part (110).

MEDICAL POLYURETHANE FOAM DRESSING AND PREPARATION METHOD THEREOF
20230270913 · 2023-08-31 ·

A medical polyurethane foam dressing and a preparation method thereof are provided in this disclosure. The medical polyurethane foam dressing includes a polyurethane film, a hydrophilic polyurethane foam layer compounded on the polyurethane film, a release paper provided on the hydrophilic polyurethane foam layer, and a soft silicone composite layer located below the release paper. The polyurethane film consists of a release film and a PU resin layer or TPU resin layer coated on the release film. Products prepared according to the disclosure not only can serve to absorb wound exudate of pressure sore, but also provides single-side water proofing; and it is sticky and can be stably fixed on the wound without easy displacement, thus ensuring continuous and stable liquid absorption.

MARKING METHOD FOR MARKING RADIATION THERAPY POSITIONING NOTE
20220152422 · 2022-05-19 · ·

Disclosed is a marking method for marking a radiation therapy positioning note, comprising in sequence: a preparing step of providing a radiation therapy positioning sticker, wherein the radiation therapy positioning sticker includes a pattern layer and a release layer disposed on an outer surface of the pattern layer, and the radiation therapy positioning note is formed on the outer surface of the pattern layer; a transferring step of attaching the radiation therapy positioning sticker onto a predetermined note position of a radiation therapy target object in a manner that an inner surface of the pattern layer faces forward the predetermined note position and covers the predetermined note position; and a removing step of peeling off the release layer from the outer surface of the pattern layer to outwardly expose the radiation therapy positioning note, which is formed on the outer surface of the pattern layer covering the predetermined note position.

REMOVABLE COVERING AND INTERACTIVE PACKAGING
20220142823 · 2022-05-12 ·

A removable covering for an object includes an adhered section that is adhered to the object (e.g., adhered to a receiving surface of the object via an adhesive layer) and a free section that is not adhered to the object. The removable covering is sufficiently flexible to allow at least partial removal of the adhered section from the object by application of a force to the removable covering. Typically, the removable covering is adhered to the object such that resistance to removal of the covering from the object varies at different zones of attachment between the removable covering and the object. The resistance variation may be achieved, for example, by employing tabs, loops, folds, varying-strength adhesive strips, textures and/or release coatings. Exemplary packaging systems (e.g., containing removable coverings and/or objects) include features such that resistance to removal of the packaging system from an object varies at different phases of removal.

Adhesive film bandage for medical compression

The present invention relates to a transparent elastic compression bandage film composite for the treatment of venous diseases and tissue lesions, comprising a transparent film layer of 5-50 microns thickness, a medical adhesive coated on at least a portion of one surface of the film layer, which is preferably hypoallergenic, a first release liner for longitudinal detachment covering the adhesive film surface and, optionally, a second release liner for longitudinal detachment to serve as a carrier, wherein the effects of elasticity and of strong adhesion add to a compression quality superior to textile European standard compression media, in the main affecting superficial varicosities and long-term wearing.

Extensible dressings

The present invention relates to dressings such as bandages or tapes improved extensibility. The present invention further relates to dressings such as bandages or tapes which are extensible so as to at least partially conform to a body contour at wound surface upon stretching of the dressing.

Transparent cover dressing application system and inclusion of label strip
