  • Patent number: 11898678
    Abstract: A bag connector system includes a first coupling element, with a self-closing seal and a housing having a fluid inlet port and a fluid outlet port, and a second coupling element, with a housing having a fluid inlet end and a fluid outlet end. The fluid inlet end is configured to displace the self-closing seal when inserted into the fluid outlet port of the first coupling element. A bag connector system optionally includes a locking mechanism to maintain the first coupling element and second coupling element in a coupled state. Uncoupling of the first and second coupling elements results in minimal fluid contamination on the outer surfaces of the coupling elements. The bag connector systems provided herein are included in medical appliances for waste management.

  • Patent number: 11717434
    Abstract: A medical device according to certain embodiments generally includes a first wall, a second wall, and a first deformable reinforcing member. The first wall and the second wall are joined to one another such that a cavity is formed between the first wall and the second wall. The cavity has an outlet opening formed at a proximal end of the medical device. The first deformable reinforcing member is attached to the first wall, and is deformable by manual application of pressure to lateral edges of the first deformable reinforcing member so as to radially distend the outlet opening. The first deformable reinforcing member includes at least one first notch formed in at least one lateral edge thereof. Each notch is configured to receive a portion of a user's digit to facilitate manual application of pressure to said lateral edges.

  • Patent number: 11241525
    Abstract: A stand-alone system for assessing wound exudates from the wound of a patient is described. The system contains functionality to detect, process and report various wound parameters. The system also may make treatment determinations based on these findings. The system may detect one or more physiological values of the wound exudates from the wound of the patient. The system may also compare detected physiological values to predetermined physiological values, in order to obtain a comparison result in real time. The system may include a processor (15) which provides an electronic signal based on the comparison result in which the electronic signal may corresponds to guidelines for treating the wound (3). The system described may be an accessory, which may be used on its own, or in conjunction with other wound treatment devices (9).
