An apparatus can include a housing defining a housing interior, an air pump positioned in the housing interior, and a plurality of resilient connectors connecting the air pump to the housing with the resilient connectors in tension so as to reduce transmission of vibration from the air pump to the housing during operation of the air pump.

What is illustrated and described is a pump assembly (1) for a pump, particularly for a miniature pump, with an electric motor (2) and with a housing unit (3), wherein the electric motor (2) has a motor shaft (5) passing freely through a motor housing of the electric motor (2) and the motor housing is connected to the housing unit (3), and wherein the motor shaft (5) is supported in the motor housing with an axial shaft play. According to the invention, at least one stabilizing element (6, 13, 14, 16) arranged outside of the motor housing is provided in order to reduce or eliminate the axial play of the motor shaft (5), with an axial compressive force or axial tensile force acting on the motor shaft (3) being applied by the stabilizing element (6, 13, 14, 16) to the motor shaft (5).

A rocking piston vacuum pump or compressor may have a sound attenuation assembly. The sound attenuation assembly may comprise a sound attenuation chamber. The chamber may have a first silencer disposed therein with sound dampening foam disposed therein. A second silencer may be disposed in series relative to the first silencer and may be disposed externally of the sound attenuation chamber.

A blood pressure monitoring device configured to attach and supply air to a blood pressure cuff can include a housing having an interior, a port configured to enable fluid communication between the interior of the housing and an interior of the blood pressure cuff, and an air intake configured to allow ambient air to enter the interior of the housing and further configured to inhibit liquids from entering the interior of the housing. The air intake can define a non-linear passageway for ambient air to enter the interior of the housing. The housing can have a first side and a first inner wall. The air intake can be defined by a first opening in the first side and a second opening in the first inner wall. The first opening can be not aligned with the second opening.

A blood pressure monitor configured to removably mount to a cuff in a substantially symmetrical position with respect to a width of the cuff can include a housing defining an interior, a first port, and a second port. The first port can: secure to a first prong of the cuff when the cuff is mounted in a first orientation; receive and secure to a second prong of the cuff when the cuff is mounted in a second orientation; and enable fluid communication between the interior and at least one of a first fluid passage within the first prong and a second fluid passage within the second prong. The second port can: secure to the second prong of the cuff when the cuff is mounted in the first orientation; and receive and secure to the first prong of the cuff when the cuff is mounted in the second orientation.

An electrocardiogram device configured to transmit at least one signal responsive to a wearer's cardiac electrical activity can include a disposable portion and a reusable portion configured to mechanically and electrically mate with each other. The disposable portion can include a base having at least one mechanical connector portion, a plurality of cables and corresponding external ECG electrodes, and a first plurality of electrical connectors associated with the plurality of cables. The reusable portion can include a cover having at least one mechanical connector portion, a second plurality of electrical connectors configured to electrically connect with the first plurality of electrical connectors of the disposable portion, and an output connector port configured to transmit at least one signal responsive to one or more signals outputted by the external ECG electrodes of the disposable portion.

An assembly for enabling a caregiver to secure a physiological monitoring device to an arm of a user can include the physiological monitoring device a cradle configured to removably secure to the physiological monitoring device and to the user's arm. The physiological monitoring device can include a first connector port configured to electrically connect to a first cable and a first locking tab movable between an extended position and a retracted position. The cradle can include a base, first and second sidewalls, a back wall connected to the base and the first and second sidewalls. The cradle can further include a first opening in the back wall configured to receive the first connector port and a second opening in the first sidewall configured to receive the first locking tab when the physiological monitoring device is secured to the cradle and the first locking tab is in the extended position.

A charging station for providing power to a physiological monitoring device can include a charging bay and a tray. The charging bay can include a charging port configured to receive power from a power source. The tray can be positioned within and movably mounted relative to the charging bay. The tray can be further configured to secure the physiological monitoring device and move between a first position and a second position. In the first position, the tray can be spaced away from the charging port, and, in the second position, the tray can be positioned proximate the charging port, thereby allowing the physiological monitoring device to electrically connect to the charging port.

An apparatus can include a housing defining a housing interior, an air pump positioned in the housing interior, and a plurality of resilient connectors connecting the air pump to the housing with the resilient connectors in tension so as to reduce transmission of vibration from the air pump to the housing during operation of the air pump.

A motorized medical suction pump has a pump assembly for generating an underpressure, a pump assembly carrier for supporting the pump assembly, and a seat for receiving an energy accumulator. The pump assembly arranged in the pump assembly carrier defines a first longitudinal axis, and the seat defines a second longitudinal axis. The pump assembly carrier forms the seat. The second longitudinal axis extends at an angle to the first longitudinal axis. This suction pump is small and compact and has good sound damping.
