A manually-actuated, constant reduced-pressure apparatus for use with a reduced-pressure system for treating tissue at a tissue site includes a flexible, collapsible member that is operable to move between a compressed position and an extended position. The collapsible member may be disposed between a carrier member and a slider member that move between a compressed position and an extended position. The carrier member and slider member are urged away from each other by a constant-force biasing member, e.g., a constant force coil spring. As the apparatus moves from the compressed position to the extended position, a constant reduced-pressure is generated and delivered to a reduced-pressure port. Methods of manufacturing a manually-actuated, constant reduced-pressure apparatus and methods of treating a tissue site are also provided.

The combination of a breast pump shield, with its ring, applied to the flange lower end of the shield, and the ring being C shaped in cross-section, having an upper flange, a lower flange, both integrally structured with a base wall. The physiological stimulator integrally formed with the lower flange of the sealing ring extends inwardly and upwardly within the shield, and therein functions as a means to place pressure upon the breast of the mother to help induce and stimulate the flow of breast milk during usage of the associated breast pump.

The wound therapy apparatus may include a wound interface sealingly securable to the skin surface around a wound bed to encloses the wound bed within an enclosed space that is fluid-tight. The wound interface may be sufficiently deformation resistant to distend at least a portion of the wound bed into the enclosed space when pressure p.sub.0 within the enclosed space is less than ambient pressure p.sub.amb. Fluid may be communicated with the enclosed space when the wound interface is sealingly secured to the skin surface in order to vary a pressure p.sub.0 within the enclosed space periodically over the pressure range p.sub.min≤p.sub.0≤p.sub.max. The variation of the pressure p.sub.0 may distend the wound bed into communication with a pad received within the enclosed space and decreases the wound bed contact with the pad. Related methods of use of the wound therapy apparatus are also disclosed.

The invention comprises a urine removal devices that enable urine discharged from a male patient's penis to be contained within a flexible pouch and drawn out of the pouch and away from the genital region of the patient through a drain tube. The pouch comprises a first fluid compartment, a second fluid compartment and a fluid transmission passageway connecting the first fluid compartment and the second fluid compartment—wherein the fluid transmission passageway comprises a thin-film unidirectional fluid flow valve configured to enable for fluid flow from the first fluid compartment to the second fluid compartment, and to prevent fluid flow from the second fluid compartment to the first fluid compartment. The pouch may have an aperture sized to permit a male patient's penis to enter the pouch within the first fluid compartment.

A negative pressure wound therapy device includes a piezoelectric pump, a state detector configured to detect a state of the pump, and a control circuit configured to transmit a first control signal for a first period having a first RMS voltage greater than or equal to a threshold voltage at which driving the pump for a second period greater than the first period can cause the pump to emit sound at a magnitude greater than a sound threshold; receive a first indication of the state; determine if the pump is in a leak condition; transmit, responsive to the pump not being in the leak condition, a second control signal having a second RMS voltage less than the first RMS voltage; and transmit, responsive to the pump being in the leak condition, a third control signal having a third RMS voltage greater than the second RMS voltage.

A pressure-controlling device (10) includes a pump (21), a connection pipe (30), a first valve (41), and a second valve (42). The pump (21) has an inlet port (211) and an outlet port (212). The connection pipe (30) has a first end in communication with the outlet port (212), and a second end in communication with the inlet port (211) and that has a first space (31) that contains the first end, a second space (32) that contains the second end, and a third space (33) that is located between the first space (31) and the second space (32).

A mobile negative pressure wound therapy (NPWT) device is described having an inlet; a canister in fluid flow connection with the inlet; a pump having a pump casing with a pump inlet in fluid flow connection with the canister in the canister, and a pump outlet for output of air transported through the pump; an elastomeric jacket at least partly enclosing the pump, the elastomeric jacket being configured to define a flow channel having a first end arranged to receive air output by the pump outlet and a second end spaced apart from the first end for discharging the air output by the pump outlet following passage through the flow channel; a control unit for controlling operation of the mobile NPWT device; a battery arrangement for powering the mobile NPWT device; and a housing enclosing at least the pump, the elastomeric jacket, the control unit, and the battery arrangement.

A pump arrangement is provided for a breast pump system having a pump motor assembly and a damping arrangement, providing a coupling between an outer surface of the pump motor assembly and an inner surface of a housing for the pump arrangement. A set of one or more limbs extends outwardly from a frame. For example, cushions are formed by a pair of radially extending limbs and a connecting piece connecting to the pair of limbs. This arrangement provides positioning within the housing as well as damping.

A nasal device includes a tip member having a first end and a second end, the second end of the tip member being oppositely disposed relative to the first end, the tip member including a first wall disposed at the first end thereof, the first wall defining a first aperture configured to be in fluid communication with a nostril of a person; a cover member disposed over a portion of the tip member, the cover member including a second wall overlapping at least a portion of the first wall of the tip member, the second wall defining a second aperture configured to be in fluid communication with the nostril of the person and the first aperture of the tip member, the cover member configured to provide a seal with the nostril of the person; and a vacuum source or a fluid container coupled to the tip member.

A hydraulic pumping system in accordance with embodiments comprises a breast interface operably coupled to an actuatable assembly by means of an actuatable assembly interface. The breast interface comprises a distal membrane coupled to a housing to form a fluid reservoir therebetween. The actuatable assembly interface comprises a proximal membrane. The distal and proximal membranes are fluidly coupled via a tube carrying a driving fluid. The actuatable assembly interface is configured to removably couple to the actuatable assembly, in order to operably couple the actuatable assembly to the breast interface. The actuatable assembly interface comprises a fluid shut off mechanism to reversibly shut off fluid communication between the breast interface and the actuatable assembly interface when the actuatable assembly interface is decoupled from the actuatable assembly.
