Various venting attachments or leak devices can be removably or permanently coupled to a surgical cannula to allow a user to vent gases, in particular smoke, from a surgical cavity. The venting attachment can be configured to vent the smoke at a predetermined rate and filter out the smoke prior to venting to atmosphere. The substantially constant venting flow rate can promote clearing of the smoke in the surgical cavity while helping to maintain a substantially constant pressure, and thus stability, in the surgical cavity.

An urethral antimicrobial delivery device (1) comprising; a deformable reservoir (101) in fluid connection with an elongate member (102), the elongate member comprising a lumen, the elongate member having a proximal end and a distal end, the elongate member having a plurality of pores (103) defined therein, said pores being distributed along a length of said elongate member, the elongate member being dimensioned for insertion through an external urethral orifice of a female subject, whereby the elongate member is insertable into a distal urethral cavity for delivery of an antimicrobial in said distal urethral cavity, and wherein the device comprises a collar (105) to prevent said elongate member entering a proximal urethral cavity.

The present invention relates to An apparatus for prompting conscious breathing in a subject comprising a deformable body having an internal volume, the deformable body having an opening in fluid communication with the internal volume and an external environment; and a valve located at the opening, wherein the valve is adapted to adjust a fluid flow rate between the internal volume and the external environment. The present invention assists in prompting conscious breathing.

A delivery device for and method of delivering a dose of substance for systemic uptake to a nasal cavity of a subject, the delivery device comprising: a nosepiece unit for insertion into a nasal cavity of a subject and comprising an outlet unit which includes at least one nozzle for delivering substance for systemic uptake substantially only to surfaces in one or both of the anterior region and an anterior section of the posterior region of the nasal cavity of the subject; and a substance supply unit which is operable to deliver a dose of substance to the at least one nozzle.

A stabilizer arm for a BVM resuscitator and method of use is disclosed. The stabilizer arm provides the necessary support to the reservoir bag to enable the user to exert downward pressure on the BVM resuscitator while simultaneously squeezing the reservoir bag, and creates force that is focused, directed, and realized at the mask of the assembly. Due to the presence of the stabilizer arm, this pressure pushes the facial mask downward to assist in forming a tight mask to face seal. The stabilizer arm may be internal, external or integrated into the reservoir bag wall of the BVM resuscitator and may be retro-fitted or original equipment manufactured. The external stabilizer arm may be designed to engage the outlet port neck of the BVM resuscitator with an open collar or a closed collar. The internal stabilizer arm may be configured to fit BVM resuscitators having single piece or multiple piece outlet valve design.

The present efficient support portable constant negative pressure suction apparatus for outdoor use includes: a negative pressure suction ball extending from the proximal end to the distal end, the negative pressure suction ball being provided with an internal sac structure; the internal sac structure includes: a round gas exhaust valve, a spherical sac, and an anti-reverse flow flap arranged in sequence from the proximal end to the distal end; and also including: a negative pressure suction tube, the negative pressure suction tube being in communication with the negative pressure suction ball and the negative pressure suction tube being provided with a suction control channel.

A pressure regulating or pressure relief device comprises an inlet and an outlet chamber with an outlet. The inlet is in fluid communication with the outlet chamber. A valve seat is located between the inlet and the outlet. A valve member is biased to seal against the valve seat, and displaces from the valve seat by an inlet pressure at the inlet increasing above a pressure threshold to allow a flow of gases from the inlet to the outlet via the outlet chamber. The flow of gases through the outlet causes an outlet pressure in the outlet chamber to act on the valve member together with the inlet pressure to displace the valve member from the valve seat.

A manual pump apparatus and method for extracting breastmilk is disclosed. A pump head comprises a funnel-shaped breast shield portion and a neck portion leading to a collection container. A deformable elastic component is sealed within an opening formed in the neck portion and manipulated by a mechanical actuation device to engage the user's nipple within the pump head to simulate the suckling of an infant and to compress the nipple to control edema. The deformable elastic component is configured to move into the interior volume of the neck portion under an applied pressure such that the deformable elastic component compresses the nipple to control nipple edema. The deformable elastic component is also configured to move away from the axial center of the neck portion under an applied pressure to create a volume to create suction and extract breastmilk in a manner that closely replicates the suckling of an infant.

Methods and devices related to the fields of skin care, hair restoration and lip care wherein the systems may be used by an individual for infusing treatment media into skin or lips for cosmetic and rejuvenation purposes, hair restoration purposes or other therapeutic purposes.

A cartridge is inserted onto a nebulizer that aerosolizes (or vaporizes) liquid drawn from a cartridge reservoir via a flow path into a nebulization chamber. In such a nebulizer, an inlet port is coupled to an external air supply and leads through a Venturi nozzle into the chamber to direct an air stream across an opening of the flow path, while a discharge port leads from the chamber to a user mask, mouthpiece or cannula, where the aerosol or vapor mixture can be inhaled. A filtered outlet port isolates exhaled material from the external environment. Multiple discrete heating elements may be placed around the flow path to preheat the liquid. If the liquid is sufficiently volatile, heating may vaporize the material which can condense back into an aerosol after mixing with the air stream. A set of check valves direct one-way flow and prevent leakage or spillage of material from the cartridge or nebulizer. The cartridge and nebulizer can receive coded information for third-party activation by an authorized establishment.
