A patient support apparatus for traversing objects supported on ground surfaces. The patient support apparatus comprises a patient support deck, and a base to support the patient support deck from the ground surface. At pair of caster wheel assemblies spaced from each other are coupled to the base for pivoting movement about respective pivot axes cooperating to define a reference plane. A frame guard coupled to the base defines first and second ramp surfaces each disposed at an angle relative to the reference plane. The first ramp surface is arranged to engage objects before they contact one or more of the caster wheels when the patient support apparatus moves in a first direction. The second ramp surface is arranged to engage objects before they contact one or more of the caster wheels when the patient support apparatus moves in an opposite, second direction.

Patient support apparatus with frame guard

A height adjustable patient support has a frame, a pair of motor powered leg assemblies operable to vertically raise and lower the frame between a lowermost position and an uppermost position, a guide structure for longitudinally guiding an end of at least one of the pair of leg assemblies along the frame as the at least one of the pair of leg assemblies operates to vertically raise and lower the frame, and a non-motorized structure operable to longitudinally bias the end of the at least one of the pair of leg assemblies when the frame is in the lowermost position, the non-motorized structure mounted on the patient support by a mounting structure non-rigidly secured to the patient support. The non-motorized structure may assist with raising the frame from the lowermost position until motors operating the motor powered legs are able to continue with raising the frame.

Leg assembly for height adjustable patient support

A lamp device is disclosed. The lamp device comprises a first electrical connector and a second electrical connector located at a first end portion of the lamp device. The first end portion of the lamp device is received in a receptacle of a first base portion. A first locking portion is included for secunng the first base portion to the first end portion. The present radiation lamp device obviates or mitigates the need to use adhesive and/or polymer insulation/O-rings to achieve electrical connections. Further, the present radiation lamp may be oriented in a vertical orientation without the need to use springs and/or rubber part to support the distal end of the lamp.

There is disclosed a cleaning apparatus for a radiation source assembly in a fluid treatment system. The clean apparatus comprises a cleaning sleeve moveable to remove fouling materials from an exterior portion of the radiation source assembly, the cleaning sleeve comprising at least one chamber for receiving a cleaning fluid and a cleaning sleeve inlet in fluid communication with the at least one chamber and a first conduit element for conveying the cleaning fluid to the cleaning sleeve inlet, the first conduit element being configured such that a distal portion of the first conduit element is in fluid communication with the cleaning sleeve inlet and a proximal portion of the first conduit element is disposed outside of fluid being treated in the fluid treatment system.

Cleaning apparatus, radiation source module and fluid treatment system

There is described In another of its aspects, the present invention provides a radiation source assembly comprising: (i) an elongate radiation source; (ii) a positioning element connected to a proximal portion of the elongate radiation source; and (iii) a connecting portion secured to a proximal portion of the positioning element and configured to engage a support element to maintain a distal portion of the elongate radiation source in a cantilevered position. The present radiation source assembly is configured such that the distal portion of the radiation source is cantilevered with the respect to the distal portion of the protective sleeve in which it is disposed. This feature obviates the need to use spacers, stops, springs and the like in a distal portion of the protective sleeve to maintain correct position of the radiation source within the protective sleeve. Further, the present radiation source assembly is advantageous in that allows for withdrawal of the radiation source from the radiation source assembly without the need to disengage all of the components. Thus, it is possible to replace a single radiation source by removing it from the protective sleeve during operation of the fluid treatment system. This operation can be accomplished quickly without the need to shut down the fluid treatment system or otherwise compensate for the fact that one of the radiation source is being serviced.

Radiation source assembly

There is disclosed an elongate radiation source cartridge. The cartridge comprises: (i) an elongate radiation source assembly having a proximal portion and distal portion, the distal portion of the elongate radiation source assembly being unsupported, (ii) a housing coupled to the proximal portion of the elongate radiation source assembly, and (iii) a power supply disposed within the housing, the power supply in electrical communication with the elongate radiation source assembly (in certain embodiments the power supply is optional). The elongate radiation source assembly and the housing are in substantial alignment with respect to a longitudinal axis of the elongate radiation source cartridge.

Radiation source cartridge and module containing same

The invention relates to an ultraviolet radiation lamp. The lamp comprises a substantially sealed cavity comprising a mercury-containing material; a filament disposed in the sealed cavity; and an electrical control element in contact with the filament, the electrical control element configured to adjust or maintain a temperature of the mercury-containing material with respect to a prescribed temperature. Such a constructions allows the present ultraviolet radiation lamp to be operated at optimal efficiency without the need to use additional components to add heat to and/or remove heat from the mercury-containing material.

Ultraviolet radiation lamp and source module and treatment system containing same

There is disclosed a lamp device including a longitudinal axis, a first elongate electrical connector and a second elongate electrical connector, each of the first elongate electrical connector and the second elongate connector being non-parallel with respect to the longitudinal axis. The present lamp device provides a reliable electric connection on the one hand, yet is relatively inexpensive, uncomplicated and simple to implement on the other hand.
