  • Patent number: 10912869
    Abstract: A portable system for subatmospheric pressure therapy in connection with healing a surgical wound, including a wound dressing dimensioned for positioning relative to a wound bed of a subject and a subatmospheric pressure mechanism dimensioned to be carried or worn by the subject. The subatmospheric pressure mechanism includes a housing having a control unit adapted to draw a vacuum and a canister associated with the housing. The canister has a collection bag disposed therein, which is in fluid communication with the wound dressing to receive exudates from the wound bed. The collection bag is adapted to expand upon receipt of the fluids and has means to release gas from within the collection bag in connection with operation of the control unit. With this arrangement, the canister is attitude independent, i.e., the canister may be positioned on edge, on its side or on its end etc. while still maintaining operation of the control unit.

  • Patent number: 10143781
    Abstract: A chest drainage container for withdrawing and collecting certain body fluids from within a patient's chest cavity includes means for tolerating the container being accidentally tipped over. To provide such means, some example containers disclosed in this patent merely involve modifying the plastic injection mold of an existing chest drainage container. In some examples, certain partitions and vents are integrally formed in the container's main body. In the event of a tip-over occurrence, the partitions trap collected fluid within their appropriate collection chambers to help prevent inter-chamber mixing of fluid. During normal operation, the vents enable a pocket of otherwise trapped air to escape from within the enclosed collection chambers as incoming body fluid displaces the air. In some examples, under certain conditions, the vent releases gaseous fluid at a volumetric flow that is about 30 times greater than what the vent releases of liquid fluid during a tip-over event.

  • Patent number: 9839726
    Abstract: A device for thoracic drainage comprises a container connector for a secretion collection container (3), which can be connected to the pleural cavity of a patient, and a venting device (10) for releasing air from the secretion collection container in passive operation. In order to keep the counterpressure as low as possible during the air release and thus make it easier to force air out of the pleural cavity (1) of a patient, the venting device has a controllable vent valve (12). For this purpose, a control device (7) determines the pressure in the secretion collection container by reading out a pressure sensor (11) and controls the valve to release air from the secretion collection container when the determined pressure exceeds a threshold value. The device can optionally also be operated actively by way of a vacuum connector (25). An ancillary line (2?) permits monitoring of the drainage line (2).

  • Patent number: 9713661
    Abstract: A drainage and/or collection system (1) for biological fluids includes at least one conduit (40) for transporting a biological fluid (F) from a catheter (10) to a collection device (50) and a gas pressure source (70) configured to feed a gas (G) into the at least one conduit (40) between the catheter (10) and the collection device (50). The gas (G) causes the biological fluid (F) arranged in the at least one conduit (40) to drain into the collection device (50). A method includes inserting a catheter (10), draining a fluid (F) into a collection device (50) via a conduit (40), and introducing gas (G) into the conduit (40) so as to force fluid (F) remaining in the conduit (40) into the collection device (50).

  • Patent number: 9679170
    Abstract: A system monitors the distribution of a disinfectant having an expiration. The system has distribution containers and use containers, each having a volume for dispensing the disinfectant. A reader of the system can read identifiers associated with the containers, and a database of the system can associate the volumes and the expiration of the disinfectant contained in each of the containers. During monitoring, processing equipment of the system tracks each of the volumes of the disinfectant, the expiration of the disinfectant, and the identifiers of the containers. For example, the processing equipment can log the dispensing of the disinfectant from the distribution container to the use containers and can log any amount of the dispensed disinfectant in the use containers that was noted used. Additionally, the processing equipment can determine that the distribution container or any of the user containers have disinfectant past the expiration.
