A wound treatment appliance is provided for treating all or a portion of a wound. In some embodiments, the appliance includes an impermeable flexible overlay for applying a reduced pressure to the covered portion of the wound. The wound treatment appliance may also include a vacuum system to supply reduced pressure to the wound in the area under the flexible overlay, a wound packing means to prevent overgrowth of the wound or to encourage growth of the wound tissue into an absorbable matrix including the wound packing means, a suction drain, a collection chamber to collect and store exudate from the wound, and/or a suction bulb which may be used to provide a source of reduced pressure to an impermeable overlay that covers all or a portion of the wound. Finally, methods are provided for using various embodiments of the wound treatment appliance.

Therapeutic powder applicators and their methods of operation are described. In some embodiments, a first flow of gas may flow through a distal porous portion of a chamber containing a therapeutic powder. This gas may fluidize and entrain the therapeutic powder and flow the entrained powder through an outlet that is in fluid communication with the chamber.

A device according to one aspect of the present invention is an intranasal powdered medicine dispensing device (10) for dispensing a predetermined dose of a powdered medicine into a nasal cavity. The device includes a nozzle member (20) that includes a filling space (22) for a powdered medicine (M) and an ejection opening (26) for the powdered medicine (M), a closing member that closes the ejection opening (26), a sealing member (40) that seals an opening (24) of the filling space (22), an injection pump member (50) that sends out air, as the injection pump member contracts, to eject the powdered medicine from the ejection opening (26), a puncturing member (60) that moves, as the injection pump member (50) contracts, and forms a hole by puncturing in the sealing member (40) while moving, and a guide member (70) that restricts the puncturing member (60) from moving in a direction perpendicular to the direction of the movement thereof.

Provided is a medical suction device including a compressible object comprising a surface, an opening in the surface, and a lumen defined by the surface and the opening, along with a tubular member located inside the compressible object. Also provided is a medical suction apparatus including the medical suction device and a catheter dimensioned to fit inside the tubular member of the device. A method of removing liquid from the throat of a subject using the medical suction apparatus is also provided, as well as kits including the medical suction device.

Presented herein are implantable systems and methods for long-term delivery of treatment substance to a recipient.

A wound treatment appliance is provided for treating all or a portion of a wound. In some embodiments, the appliance comprises an impermeable flexible overlay that covers all or a portion of the wound for purposes of applying a reduced pressure to the covered portion of the wound. In other embodiments, the impermeable flexible overlay comprises suction assistance means, such as channels, which assist in the application of reduced pressure to the area of the wound and removal of exudate from the wound. In other embodiments, the wound treatment appliance also includes a vacuum system to supply reduced pressure to the wound in the area under the flexible overlay. In yet other embodiments, the wound treatment appliance also includes wound packing means to prevent overgrowth of the wound or to encourage growth of the wound tissue into an absorbable matrix comprising the wound packing means. In still other embodiments, the appliance may include a suction drain. In other embodiments, the appliance may include a collection chamber to collect and store exudate from the wound. In yet other embodiments, a suction bulb may be used to provide a source of reduced pressure to an impermeable overlay that covers all or a portion of the wound. Finally, methods are provided for using various embodiments of the wound treatment appliance.

Deformable valves and atomizer designs for a vaporizer (e.g., electronic cigarette). The vaporizer may be used for vaporization of liquid and/or organic material. The vaporizer may enable enhanced flow control of fluid and may generate high quality and quantity of vapor efficiently. In some instances, flow path of the vaporizer may allow bulk fluid flow, e.g., in contrast to capillary flow, to deliver fluid to a vicinity of the vaporizer. In some instances, the vaporizer may utilize improved atomizer designs for vaporizing devices, where said designs can be configured optionally, with various embodiments of a breath-modulating deformable valve.

Various implementations include an endotracheal tube assembly including an endotracheal tube, an inflatable annular air cuff, an annular slider cuff, an air cuff tubing, and a pointer. The tube includes a visual indicator portion adjacent the proximal end of the endotracheal tube. The inflatable annular air cuff is disposed around the exterior surface of the endotracheal tube and is affixed to the distal end of the endotracheal tube. The annular slider cuff is slidably disposed around the endotracheal tube, and the slider cuff is affixed to the air cuff. The air cuff tubing is coupled to the slider cuff, and the pointer is coupled to the air cuff tubing proximal to the visual indicator portion. Axial movement of the slider cuff causes movement of the pointer relative to the visual indicator portion indicates movement of the endotracheal tube within the trachea during use.

A breast pump (1) comprises a cup member (2) and a container (3). The cup member (2) has a breast engaging portion (4) configured to seal to a breast. The container (3) is configured to be removably and sealingly connected to the cup member (2). The container (3) is configured to be deformed by a user and released to create suction on the breast to pump breast milk into the container (3). A breast pump (1) and feeding kit for pumping, storing and feeding breast milk is also disclosed. The kit comprises a deformable container (3) which may be attached to one of a cup member (2), a teat (18), or a lid (32). The teat (18) is configured to feed breast milk from the container (3) to a baby. The lid (32) is configured to secure the breast milk in the container for storage.

Methods and devices for delivering a dose, such as a medicament, for inhalation. A dose may be stored by a delivery device and dispersed and delivered in a metered fashion to a subject, such as by the subject inhaling via a mouthpiece of the delivery device. One or more chambers of the device may have a toroidal shape and may be arranged to be selectively opened for fluid communication with a flow path of the delivery device, such as by sliding the chamber relative to a portion of the flow path. The flow path may include a restriction that permits air to bypass the chamber, and/or the chamber may be arranged so that fluid entering the chamber interacts with fluid exiting the chamber so as to enhance dispersion of the dose.
