A waste collection unit including a waste container, and vacuum source to collect medical waste into the waste container. The vacuum source is disposed within a sound attenuating enclosure that defines an enclosure inlet for receiving cooling air and an enclosure outlet for discharging warmed cooling air. The sound attenuating enclosure is at least partially formed of a sound-absorbing material and may define a pocket for receiving a first end of the vacuum source. The first end of the vacuum source may engage a seat of the sound attenuating enclosure to provide a cooling air barrier. The seat may define a bottom portion of the pocket. Internal geometries of the sound attenuating enclosure may be shaped to define another air path that does not pass through the vacuum source. A plenum may be attached to the sound attenuating enclosure and define a plenum chamber to collect the warmed cooling air.

An injection system includes: a syringe having a cylinder to be filled with a chemical liquid, a flange projecting laterally from the cylinder, an end portion through which the chemical liquid passes when the chemical liquid is pushed out, and a syringe screw portion formed on a side opposite to the end portion; an adapter for holding the syringe, the adapter having a receiving portion for receiving the cylinder, a regulating wall for abutting the flange, and an adapter screw portion engaged with the syringe screw portion; and an injection device provided with a holder to which the adapter is to be attached. In this injection system, a tightening direction by the syringe screw portion and the adapter screw portion is set in a direction toward the end portion.

A light emitting device with a rotating form thereon, said device having a motor and a power source contained within a generally durable housing having a lens and an elongated spire extending outside of the durable housing and through an opening contained within the lens, said elongated spire additionally having a decorative rotatable form positioned on a distal end of the elongated spire, and at least one light source directing emitted light at the rotatable form, such that crisp hard shadows are produced on outlying surfaces. A power source is provided, connected to a motor and processor so as to move or rotate the spire and thus the form, causing the lights to cast moving decorative shadows on an exterior surface.

A respiratory ventilator device is described herein. The respiratory ventilator device includes an inhaled air assembly, an exhaled air assembly, and a control system operatively coupled to the inhaled air assembly and the exhaled air assembly. The inhaled air assembly is coupled to a patient respiratory circuit and configured to channel a volume of inhalation air to the patient's lungs to assist in patient inhalation. The exhaled air assembly is coupled to the patient respiratory circuit and configured to remove air from the patent's lungs to assist in a patient exhalation. The control system is configured to operate the respiratory ventilator system in an inhalation mode and an exhalation mode.

An active breathing assistance apparatus is disclosed. A simple apparatus includes first, second and third sets of balloons in a base compartment; a compression component on or over the balloons, configured to expel air from the balloons; a tubing network connected to the balloons; a wearable breathing compartment at an outlet of the tubing network; first and second check valves in the tubing network, between the breathing compartment and (i) the third set of balloons and (ii) the first and/or second balloons, respectively; third and fourth check valves between atmospheric air and the first and second balloons, respectively; a cover securing the compression component to the base compartment; and a motion restricting component controlling movement of the compression component. The first and second sets of balloons are between the compression component and the base compartment, and the third set of balloons is between the compression component and the cover.

A valve apparatus comprises a housing having an inlet port, an outlet port, a selectable flow port, and a vent. The apparatus further comprises a valve member which is moveable between:

a first position in which a flow path between the inlet port and the selectable flow port is substantially blocked and in which the vent is fluidly connected to the selectable flow port; and

a second position in which a flow path between the selectable flow port and the vent is blocked, and the selectable flow port is fluidly connected to the inlet port.

A device for performing a tracheotomy on a patient without the assistance of a medical professional. The device may include one or more mechanical arms that cause a blade to create an incision, cause a dilating tool to dilate the incision, and cause a tracheotomy tube to be inserted into the incision. The device may further include a scanner and/or a hollow needle connected to an air pressure sensor that may be used to detect whether the device is aligned with the patient's airway.

A droplet delivery device and related methods for delivering precise and repeatable dosages to a subject for pulmonary use is disclosed. The droplet delivery device includes a housing, a reservoir, and ejector mechanism, and at least one differential pressure sensor. The droplet delivery device is automatically breath actuated by the user when the differential pressure sensor senses a predetermined pressure change within housing. The droplet delivery device is then actuated to generate a stream of droplets having an average ejected droplet diameter within the respirable size range, e.g, less than about 5 μm, so as to target the pulmonary system of the user.

The invention relates to an apparatus comprising an electromechanical device, a control unit, a main control unit and a motion detector, wherein said control unit is configured to control said electromechanical device. The invention also relates to a method for operating an apparatus with a main control unit, a control unit and an electromechanical device. The technical problem of providing an apparatus with an electromechanical device, the reliability of which is improved, is solved by an apparatus wherein the main control unit is configured to provide information to the control unit. The motion detector and the main control unit are configured such that information about the movement of the electromechanical device is provided by the motion detector at least to the main control unit. The technical problem is also solved by a method for operating an apparatus, in particular an apparatus or medical device according to the invention.

A hand-held dispenser to dispense fluid includes a casing to fit into a hand of a user, a nozzle in the casing to dispense a mist, a fluid reservoir contained in the casing to hold a fluid to be turned into the mist, a filament extension atomizer contained in the casing to generate the mist, an air source contained in the casing to provide air flow to direct the mist to the nozzle, a motor contained in the casing to operate the filament extension atomizer, an actuator positioned on the casing to activate the dispenser, a control circuit contained in the casing to receive a signal from the actuator and to send a signal to the motor to cause the motor to actuate, and a power source contained in the casing to provide power to the motor upon receive a signal from the control circuit.
