  • Patent number: 10828211
    Abstract: A hospital bed, trolley or lifter includes a steering wheel mounted on a wheel support arm extending from which is a ratchet mechanism which can co-operate with a tooth of an adjustment mechanism. When the tooth is engaged in the ratchet teeth of the ratchet mechanism the wheel can be raised and held in the raised position until the tooth is disengaged. The wheel adjustment mechanism also includes an eccentric wheel for raising the tooth in a periodic manner to cause periodic raising of the wheel. A damper is attached to the support arm for dampening the drop of the wheel when the tooth is disengaged. A mechanism provides a steering wheel which can be held at intermediate positions between its uppermost and lowermost positions and which can be held in an engaged position in a plurality of different positions relative to casters of the bed or trolley. The system can also make use of a small capacity drive motor whilst still retaining speed of operation.

  • Patent number: 10648659
    Abstract: Patient handling equipment, such as a hospital bed, is provided with a propulsion system and a status indicator light system incorporated in the propulsion system and operable to generate at least two light beams beyond a perimeter of the bed. The light indicator, which may have different colors, shapes or intensities, can indicate the state of propulsion of the system and generates light beams which are visible all around the equipment so as to be visible to a carer from any angle. The apparatus may include an ambient light sensor disposed to detect floor level lighting conditions rather than general ambient light.

  • Patent number: 10617578
    Abstract: A brake assist system for patient handling equipment such as a patient bed includes a drive wheel. The wheel includes a brake assist system operated by control of a controlled unit which is operable to sense tilt of the handling equipment and to apply partial breaking to the wheel when it is detected that the equipment is on a slope. The control unit controls a maximum speed of the equipment down the slope, in order to protect the patient and to assist a care worker. The control unit disengages the brake assist mechanism when it is detected that the equipment is on a horizontal surface.

  • Patent number: 9937943
    Abstract: An assisted propulsion system, method and chassis for conveying a payload along a surface are described. A plurality of wheels disposed about the chassis support it on the surface. A drive provides at least assisted propulsion to the chassis along the surface. At least a driving part of the drive is connected to the chassis via a mount having a resiliently sprung link. At least the driving part of the drive has a fixed orientation and is moveable independently of the chassis and the plurality of wheels in a direction towards the surface. The resiliently sprung link is arranged to direct at least the driving part onto the surface during provision of the assisted propulsion. A sensor is arranged to monitor acceleration of the drive and to communicate data on acceleration to a controller, which controls operation of the drive in dependence on the data received from the sensor.

  • Publication number: 20110178818
    Abstract: An activity log system for patient handling equipment, for example a hoist, comprises an accelerometer (3) mounted on the patient handling equipment (10, 11, 12, 13). The accelerometer together with a microprocessor logs data over time, so that movement of the equipment is measured and recorded. The data collected is transmitted to a main control unit (15), in contact with other activity log systems (1), which matches logged data with experience data to enable mapping of equipment usage over time.

  • Patent number: 6511461
    Abstract: A needle holding device having an elongated hollow body with first and second ends, the first end being substantially open for receiving a needle. The hollow body also has a locking member operably disposed therein or thereon. The locking member has an opening to receive and non-releasably hold a needle inserted therethrough. Preferably, the locking member has one or more protrusions directed inwardly toward said opening, the protrusions being adapted to engage a needle in a locking relationship when the needle is inserted through the opening in the locking member. Also preferably, the needle holding device has an elastomeric sealing member operably connected to the hollow body, the elastomeric sealing member also being disposed adjacent the first end of said hollow body. The elastomeric sealing member is adapted to admit and seal around a needle pierced therethrough.

  • Publication number: 20020018999
    Abstract: Methods are described for analyzing at least one polymorphic site in a biological sample containing at least one single-stranded template, including the steps of: combining the biological sample with a primer specific for each polymorphic site in each template and a primer extension preparation, to form an assay mixture; wherein the preparation includes: chain terminating nucleotides forming a first nucleotide class, chain elongating nucleotides forming a second nucleotide class such that the second nucleotide class does not include a nitrogenous base present in the first nucleotide class, and a template-dependent nucleic acid polymerase; incubating the mixture for a time and at a temperature sufficient to extend each primer by addition of at least one nucleotide; and determining the size of each extended primer. Kits suitable for practising the invention are also provided.
