The present invention relates to a negative pressure wound therapy device, system and method. The negative pressure wound therapy device is connected with a dressing, and comprises a housing, a control circuit board, a pump, and an aspiration conduit. The pump generates negative pressure. The pump may comprise a voltage-actuated deformation element (such as piezoelectric vibration element) to push fluid from an aspiration end to a discharge end. The aspiration conduit has a pump end and a dressing end. The pump end is fluidly connected to the aspiration end of the pump, and the dressing end is fluidly connected to the dressing used for covering a wound. The control circuit board is disposed in the housing, controls the pump to generate the negative pressure in the aspiration conduit, and applies negative pressure to the wound covered by the dressing via the aspiration conduit.

A surgical system is disclosed including an end effector, a control circuit, a closure member, and a firing member. The end effector includes a first jaw, a second jaw, and an electrode. The first jaw is rotatable relative to the second jaw between an open position and a close position to capture tissue therebetween. The electrode is configured to conduct a sub-therapeutic RF current to the tissue. The control circuit is operably coupled to the electrode. The control circuit is configured to measure impedance of the tissue over time based on the sub-therapeutic RF current. The closure member is configured to move the first jaw towards the second jaw at a closure rate based on the impedance of the tissue. The firing member is configured to move within the end effectors towards a fired position at a firing rate based on the impedance of the tissue.

A portable urinal device includes a base forming a liquid receptacle. Tubing extends from the base to a head member which can be positioned onto genitalia for urination. Suction is provided via a pump or vacuum device to suction urine from the head into the base receptacle.

Urine collection systems and associated methods and devices are disclosed herein. A representative system can include a urine collection device, a flow control assembly configured to direct a urine flow from the patient to the urine collection device, and a urine measurement device including a first sensor and a second sensor. The first sensor is configured to generate first sensor data based on a weight of the container, and the second sensor is configured to generate second sensor data based on the urine flow from the patient to the container. The system can further include non-transitory computer readable media having instructions that, when executed by one or more processors, cause the system to perform operations comprising determining a first patient urine output based on the first sensor data; and determining a second patient urine output based on the second sensor data.

Systems and methods for pumping milk from a breast, wherein the milk is expressed from the breast under suction and milk is expulsed from the pumping mechanism to a collection container under positive pressure.

Embodiments of negative pressure wound therapy systems and methods are disclosed. In one embodiment, an apparatus includes a housing, negative pressure source, circuit board, and one or more controllers. The circuit board can be supported by the housing and include a conductive pathway extending around at least part of a perimeter of a first side of the circuit board. The conductive pathway can be electrically coupled to an electrical ground for the circuit board. The one or more controllers can be mounted on the circuit board and activate and deactivate the negative pressure source.

In some illustrative examples, a bridge suitable for treating a tissue site may include a bridge sealing member and one or more bridge wicking layers. The bridge sealing member may extend along a length of the bridge, and may define an internal passageway in fluid communication between a receiving end of the bridge and a transmitting end of the bridge. The one or more bridge wicking layers may be disposed within the internal passageway of the bridge sealing member. Other apparatus, systems, and methods are disclosed.

Negative pressure wound therapy apparatuses and dressings, and systems and methods for operating such apparatuses for use with dressings are disclosed. In some embodiments, controlling the delivery of therapy can be based on monitoring and detecting various operating conditions. An apparatus can have a controller configured to monitor the duty cycle of a source of negative pressure and, based on the monitored duty cycle, determine whether a leak is present. The controller can be configured to provide an indication that a leak is present. For example, the controller can be configured to suspend and/or pause the delivery of therapy, and to restart the delivery of therapy due to a timeout, request from a user, etc. In addition, the controller can be configured to pause and/or restart the delivery of therapy upon a request from the user, such as in response to the user operating a switch.

A peristaltic pump includes a first motor shaft, a second motor shaft, a first pump head, a second pump head, and a motor. The first pump head is operably coupled to the first motor shaft such that the first pump head is rotated in response to rotation of the first motor shaft. The second pump head is operably coupled to the second motor shaft such that the second pump head is rotated in response to rotation of the second motor shaft. The motor is configured to rotate the first and second motor shafts. The pump head has a first mode in which the first pump head is rotated and the second pump head is idle and a second mode in which the first pump head is idle and the second pump head is rotated.
