The present invention discloses a hands-free wearable breast pump which includes: a main pump body, a milk reservoir, a tee piece, an airbag and a duckbill valve. The main pump body is provided with a mounting cavity having an opening in a front end surface of the main pump body; the tee piece includes a first port, a second port for mounting the airbag and a third port for mounting the duckbill valve; the airbag is mounted to the second port; the duckbill valve is mounted to the third port; the milk reservoir is mounted to the tee piece or the main pump body; the duckbill valve is in fluid communication with the milk reservoir; the main pump body has at least one pushing and positioning structure formed in the mounting cavity; the tee piece is detachably mounted in the mounting cavity and abuts against the at least one pushing and positioning structure; and the tee piece is pushed upward by the at least one pushing and positioning structure to press an open end of the airbag tightly against a side wall of the mounting cavity. The hands-free wearable breast pump has the advantages of excellent sealing performance and convenient disassembly and assembly.

A filtering device for removing particles from a fluid of a patient is provided. The filtering device being implantable in the patient's body and comprising a cassette comprising a revolving member, said revolving member having at least two segments each holding a respective filter. The device further comprises a tube forming a fluid passageway through one of the filters in said cassette, wherein the cassette is adapted to, upon revolution of the revolving cylinder, change the filter positioned in the fluid passageway from a first one of said filters to a second one of said filters, thereby allowing particles present on the first filter to be moved away from the fluid passageway, while at the same time changing the filter positioned in the fluid passageway.

A blood clot removal method for removing blood clots from the vascular system of a patient, the blood clot removal method carried out on an implantable device in the patient's body and comprising: allowing a blood flow through a passageway between a first side wall and a second side wall, filtering blood clots with a filter provided in the blood flow passageway, and cleaning the filter with a cleaning device, wherein the cleaning device is moved from the first side wall towards the second side wall to move blood clots away from the blood flow passageway.

The present application relates to a breast pump. The breast pump has a chamber (12) and a membrane (22). The membrane (22) is receivable in the chamber (12) to separate the chamber (12) into first and second spaces (23, 24). The membrane (22) is also deformable in the chamber in response to a reduction of pressure in the first space (23) to cause a reduction of pressure in the second space (24). A limiter (16) is in the chamber (12) against which the membrane (22) is locatable to limit deformation of the membrane (22).

An apparatus for negative-pressure treatment may include an enclosure having a variable volume compressible to a minimum volume, a port and an actuation surface. The apparatus may include a first one-way valve configured to allow fluid ingress to the enclosure, a second one-way valve configured to allow fluid egress from the enclosure, and an actuator configured to apply a compressive force to the actuation surface. The apparatus may further comprise a motor coupled to the actuator to apply and remove the compression force and having an operating parameter indicative of the variable volume. The apparatus may further comprise a controller coupled to the motor and configured to turn on the motor to engage the actuator to alternately apply and remove the compressive force until the enclosure is compressed to the minimum volume and turn off the motor in response to the operating parameter indicating that the chamber is compressed to the minimum volume.

A trocar includes a shaft having a leading section, a trailing section, a reduced diameter midsection located between the leading and trailing sections, and a longitudinal axis extending along the length of the shaft. The leading section of the shaft has a tapered region that terminates at a blunt tip. The trailing section of the shaft has a connector located at the trailing end thereof. The leading and trailing sections of the shaft having a first diameter and the reduced diameter midsection of the shaft has a second diameter that is smaller than the first diameter for enabling the shaft to be bent at the reduced diameter midsection. A flexible wound drain catheter having a first end is secured to the connector at the trailing end of the trailing section of the shaft. The flexible wound drain catheter has an outer diameter that matches the first diameter of the leading and trailing sections of the shaft.

A breast milk collection and storage system is disclosed that comprises a manual breast pump. The manual breast pump comprises a breast cup configured to engage with a mother's breast. The breast cup comprises an opening. The manual breast pump also comprises a reservoir at a base of the breast cup configured to receive breast milk through the opening and collect breast milk extracted from the mother's breast. The breast milk collection and storage system also comprises a stopper configured to seal the opening to prevent leakage of breast milk from the reservoir. The breast milk collection and storage system further comprises a capsule configured to enclose the manual breast pump with the stopper and apply a compression force to the stopper to maintain the seal of the opening when the capsule is closed.

A negative pressure wound treatment system comprising a bandage portion and a negative pressure portion. The bandage portion includes a dressing portion in contact with a wound and a sealing layer positioned in contact with the dressing portion. The sealing layer includes an adhesive creating a seal around the wound. The negative pressure portion is in fluid communication with the bandage portion and includes a first valve and a second valve. The first valve is in fluid communication with the bandage portion and the negative pressure portion. The second valve is in fluid communication with the negative pressure portion and the surrounding environment. The negative pressure wound treatment system is configured to provide negative pressure to an area sealed by the bandage portion upon the actuation of the negative pressure portion. The negative pressure portion is configured to be actuated by compressing the negative pressure portion while walking.

A system includes a breast shield configured to mount to a breast during a breast milk letdown process. The breast shield includes one or more sensors integrally mounted thereon. The system also includes an analyzer configured to collect and analyze data obtained by the one or more sensors to extract information reflecting a condition of the breast.

An implantable drainage device is provided. The device is adapted to move body fluid from one part of the body of a patient to another part of the body.
