  • Patent number: 11185435
    Abstract: The purpose of the invention is to create a urine bag that can be easily folded in order to occupy less space prior to use and that can be easily manipulated by a patient, in particular a paraplegic patient. This is achieved using a urine collection bag (1) formed by two sheets of plastic material that are stacked and welded along the periphery (2) thereof. The collection bag (1) comprises a collection compartment (3), said inlet being in communication with the intake port (4) and delimiting the upper portion of the collection compartment (3). The intake port (4) is provided with a vertical extension (8) closed along their periphery (22) thereof and comprising a urinary catheter (9). The bag (1) of the invention is characterised in that the intake port (4) and the inlet (6) are offset vertically, and in that the vertical height (ho) of the bag (1) corresponds to a multiple of the height (hp) of the extension (8).

  • Patent number: 11173240
    Abstract: Embodiments of negative pressure wound therapy systems and methods are disclosed. In one embodiment, an apparatus includes a driving circuit that supplies a driving signal to a negative pressure source to cause the negative pressure source to provide negative pressure via a fluid flow path to a wound dressing. The apparatus furthers include a controller that adjusts a frequency of the driving signal supplied by the driving circuit according to a comparison of a previous magnitude and a subsequent magnitude of the driving signal while the negative pressure source provides negative pressure. The transfer of power to the negative pressure source can thereby be tuned to maximize an amount of power transferred to the negative pressure source.
