A wound care device for delivering topical oxygen therapy, negative pressure wound therapy, and a low intensity vacuum therapy for treatment of a wound. The wound care device may include an oxygen supply MEA, an oxygen consuming MEA, a vacuum pump and motor, a pressure sensor, and a power supply and electronic controls. A dressing may be connected to the wound care device for administering topical continuous oxygen therapy and simultaneous negative pressure wound therapy to a wound. A canister or exudate trap may be positioned between the dressing and the vacuum supply port of the vacuum pump to collect and store exudates from the wound. The canister may be combined with the dressing.

An example fluid collection assembly includes a fluid impermeable barrier defining at least one opening, a chamber, and at least one fluid outlet. The fluid collection assembly also includes at least one porous material disposed in the chamber. The fluid collection assembly further includes at least one inflation device. The inflation device includes bladder having one or more walls defining an interior region. The inflation device also includes at least one valve configured to selectively permit fluid flow into and out of the interior region to switch the bladder between a first state and a second state. The inflation device may at least one of controllably change the length of the fluid collection assembly or controllably change a width of at least a portion of the fluid collection assembly to more comfortably fit the fluid collection assembly within the labia folds of an individual using the fluid collection assembly.

The utility model discloses a urinary catheter for women and peristaltic pump, which comprises a body tube with an inner surface and an outer surface, and further comprises an external urethral orifice fixing part which can at least sleeve the catheter tip end inside when applied, a flexible urethral guide part, a urinary catheter driving part sleeved with the cylindrical body of the external urethral orifice fixing part, a hydrophobic part for leakage stop at the urinary outlet of the urinary catheter, a thin segment, a pump tube, a tube bed and other special structures for dilating the narrowed part of the urethra, which not only eliminate the defect of the traditional “non-guided suspended placement” in a safe mode of “US-guided adjacent placement” and completely avoid contamination of the urinary catheter by the periurethral tissue, but also avoid the injury of urethral intima caused by urethral stricture in the placement procedure to the greatest extent; avoid contamination of the urinary catheter outlet by urine outflow; effectively clear the blockage of urine inlet due to blood clots and tissue masses in bladder during indwelling, and can also minimize the residual urine volume when used in conjunction with a special peristaltic pump.

A method for controlling an operation of an ultrasonic blade of an ultrasonic electromechanical system is disclosed. The method includes providing an ultrasonic electromechanical system comprising an ultrasonic transducer coupled to an ultrasonic blade via an ultrasonic waveguide; applying, by an energy source, a power level to the ultrasonic transducer; determining, by a control circuit coupled to a memory, a mechanical property of the ultrasonic electromechanical system; comparing, by the control circuit, the mechanical property with a reference mechanical property stored in the memory; and adjusting, by the control circuit, the power level applied to the ultrasonic transducer based on the comparison of the mechanical property with the reference mechanical property.

A method for capturing dislodged vegetative growth during a surgical procedure is provided. The method includes maneuvering, into a circulatory system, a first cannula having a distal end and an opposing proximal end, such that the first cannula is positioned to capture the vegetative growth en bloc. A second cannula is positioned in fluid communication with the first cannula, such that a distal end of the second cannula is situated in spaced relation to the distal end of the first cannula. A suction force is provided through the distal end of the first cannula so as to capture the vegetative growth. Fluid removed by the suction force is reinfused through the distal end of the second cannula. Subsequent to becoming dislodged, the vegetative growth is captured by the first cannula. A method for capturing a vegetative growth during removal of a pacemaker lead is also provided.

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.

An apparatus for mechanically coupling a motor to a rotor includes an outer ring including an inner surface shaped to define multiple recesses, an inner ring disposed within the outer ring and shaped to define multiple compartments having respective outer openings, which face the outer ring, and respective inner openings opposite the outer openings, and multiple gripping elements disposed within the compartments, respectively. The inner ring is configured to receive the rotor while the compartments are aligned with the of recesses, by virtue of the gripping elements sitting at least partially within the recesses. The outer ring is configured to couple with a shaft coupled with the motor such that rotation of the shaft by the motor causes the compartments to become misaligned with the recesses, thereby causing the outer ring to push the gripping elements, through the outer openings, against the rotor, through the inner openings.

A negative pressure device for applying to skin is configured to define a sealed enclosed three-dimensional space when at least a portion of the device is sealed against the skin. The device includes a body including at least one expandable segment that is configured to expand after the device has been sealed against the skin.

A method of compressing tissue during a surgical procedure is disclosed. The method comprises obtaining a surgical instrument comprising an end effector, wherein the end effector comprises a first jaw and a second jaw, establishing a communication pathway between the surgical instrument and a surgical hub, and inserting the surgical instrument into a surgical site. The method further comprises compressing tissue between the first jaw and the second jaw, determining a location of the compressed tissue with respect to at least one of the first jaw and the second jaw, communicating the determined location of the compressed tissue to the surgical hub, and displaying the determined location of the compressed tissue on a visual feedback device.
