Multiple plane camshafts may include a number of half drive plates arranged around a drive block and secured to a base washer through a scroll block. The variable camshaft may be incorporated into portable, motorized or manual, bag valve mask based resuscitation devices or similar ones.

A Housing for an infusion pump cartridge adapted to enclose a glass vessel having an open proximal end closed by a slidable piston and a distal end provided with a neck is provided. The housing is made of plastic. The proximal end is provided with a pair of bayonet fitting formations integrally formed on the housing and adapted to enable the cartridge to be fastened to an infusion pump and with connection means adapted to be arranged at the distal end of the vessel for connection to an infusion set. The housing consists of a cylindrical base part, which is provided with an inner flange for abutment of the vessel and on which the fitting formations are formed, and a neck part that can be fastened to the base part by means of snap fitting formations for retaining the glass vessel between the base part and the neck part.

A spray canister device is provided including a canister containing a liquid product, a canister housing having an opening, a chassis element, and a tray slidably coupled to the chassis element. The canister includes an actuator cap and is positioned in the canister housing such that a nozzle of the actuator cap is positioned proximate the opening. The canister housing, and the canister positioned therein, may be engaged with the tray via at least one protruding member. Once engaged, the tray may be slidably moved along the chassis element between a retracted position and an extended position to facilitate relative movement between the canister and the canister housing to compress the actuator cap of the canister and spray the liquid product.

A method of implanting a penis erection stimulation system into a patient's body comprises cutting the skin of the patient body, dissecting free an area near the left and right corpus cavernosum, placing a drug delivery device within the dissected area and placing at least one infusion needle of the drug delivery device in a first position in the patient's body in between the left and right corpus cavernosum.

Delivery systems and methods for forming and delivering biomaterials from two components are described herein. In particular, apparatus and methods for performing controlled delivery of multicomponent delivery of biomaterials into or onto a body part, such as a body lumen are described. More specifically, in some embodiments, the apparatus and methods are directed towards controlled delivery of micro-volumes of biomaterials into or onto a target location, the micro-volumes being defined as 0.001 mL-1 mL (or 1 μL-1,000 μL) of volume.

A battery-operated foam inhalation device which comprises a cartridge (610) having a liquid for producing a foam and a foam outlet (654). Agitation means agitates the liquid to produce the foam, and the agitation means comprises an electric motor (762) and a battery (760) for energising the electric motor (762). A carrier (672) receives the cartridge (610) and has a carrier foam inlet (680) for fluid communication with the foam outlet (654) of the cartridge (610). A carrier foam outlet (682) dispenses the foam to a user.

A positive air way pressure mask includes a mask body having an inlet and an outlet, a nasal interface supported on the body, the nasal interface having air passages, with the nasal interface coupling a user's nose to the outlet of the continuous positive air way pressure mask body, and an air switch device having an input port, an output port, and a diversion port, with the input port receiving air from a continuous positive airway pressure machine and delivering the received air to the output port during an inhalation, and that switches the air from the positive airway pressure machine from the inlet to the diversion port to expel diverted air to ambient during an exhalation. Also disclosed is an alternative voice coil actuated air switch device having an input port and an output port, with the input port receiving air from a continuous positive airway pressure machine and delivering the received air to the output port during an inhalation, and that inhibits the air from the positive airway pressure machine from entering the voice coil actuated air switch during an exhalation.

A bilaterally driven intelligent control infusion device, comprising: infusion unit, the infusion unit comprises a drug storage unit, a piston and a rigid screw, the piston is arranged in the drug storage unit, a metal piece arranged on the piston, fixedly connected to the rigid screw; a driving wheel, provided with wheel teeth, drives the screw movement by rotation, the screw advances the piston to move; a driving unit cooperating with the driving wheel; and a power unit, connected to the driving unit, outputs forces in two different directions on the driving unit to lead driving unit to pivot; a position detector, interacted with the metal piece to generate signal; a program unit, connected to the infusion unit, convert the received signal into the piston position information and can control the driving unit to operate with different infusion rate according to requirements.

A patient interface includes a shell with a central opening configured to receive the pressurized flow of air, a foam cushion, and an elastomeric support portion that is attached to the shell, supports the foam cushion, and forms at least part of a chamber together with the shell and the foam cushion. The elastomeric support portion includes a side wall that forms a continuous perimeter around the chamber and a resiliently flexible lip that supports the foam cushion and extends from the side wall toward an interior of the chamber. The resiliently flexible lip has an outer perimeter that is anchored to the side wall and an unsupported inner perimeter. The foam cushion overhangs the inner perimeter of the resiliently flexible lip, and the shell is more rigid than the elastomeric support portion. In addition, the foam cushion is configured to directly contact and engage a portion of the patient's skin in use.
