ADC readings are made for each of several range bins in intervals during the receive gate-open interval. One or two of the Doppler audio signals will contain the signal from the fetal heart. When a periodic signal is found, its rate is tested to see if it lies within or outside the typical range of a fetal heart.

Fetal heart rate monitoring using ultrasound by means of a transducer in contact with the maternal abdomen. The transducer (11) is driven by a transmit amplifier (12), a receive amplifier (13) amplifies the echoes detected by the transducer. While the receive gate is open, demodulator (14) multiplies the received signal by the local oscillator signal.

The apparatus comprises an inflatable sleeve 6 to be wrapped around a limb, typically a thigh, of a patient. The sleeve 6 comprises three inflatable chambers 3, 4, 5. Inflation is controlled by a pump 1 so that the distal chamber 3 is inflated first to a low pressure to act as a tourniquet, followed by inflation of the central chamber 4 to a pressure to drive fluid flow upwards, and then inflation of the proximal chamber 5 to a low pressure to act as a tourniquet and deflating both the distal 3 and central 4 chambers to produce a negative pressure gradient down-stream in the limb causing fluid to be drawn up the limb. This cycle is repeated a number of times over a period of two minutes before allowing the limb to rest for two minutes, resulting in increased mean arterial blood flow.

The four cuffs are applied to each limb (or finger or toe), each chamber is inflated simultaneously to a pressure until a Pneumo Arterial Plethysmography (PAPG) signal related to the arterial flow in the limb is detected at the chambers. The chambers are then simultaneously inflated until the PAPG signals are extinguished in each limb, the inflation of chambers continuing for 10 mmHg to 20 mmHg above that pressure. The chambers are then deflated and the pressure at which the PAPG signal returns in the first chamber is recorded for each limb and this value of the pressure is used to calculate the ABPI. The ABPI is displayed or sent to a remote site.

As the air flows through the connection tubing and through the connector a pressure wave is generated by the valve and fed back upstream to a pressure sensor in the pump. The shape of the pressure waveform identifies a particular compression garment, the pump supplying the appropriate inflation regime upon detection of this pressure waveform.

The cells (13) are numbered (1) to (12), with (1) being at the toe, or the wrist, and (12) being at the thigh, or the shoulder. In use, the inflation sequence begins with a peristaltic wave at cell (1) and finishes at cell (12). Then cell (12) is inflated and deflated 5 times, then cell (11) is inflated and deflated 5 times in the same way as cell (12), followed by a single peristaltic wave beginning at cell (12) to cell (11). This compression regime is repeated along the compression sleeve until cell (1) is inflated and deflated (5) times followed by a peristaltic wave from cell (1) to cell (12). The described compression sequence is particularly useful for lymphatic drainage.
In various embodiments, a support system includes a multi-layer cover sheet with a number of layers. In certain embodiments, a source to move air inside and outside the multi-layer cover sheet can be provided. The source can include a source of positive pressure or negative pressure.

A47C 21/04 - Devices for ventilating, cooling or heating
A system and method for a bed transport. The system may include a drive system configured to couple to a bed frame and to provide powered movement of the bed frame. The system may also include a substantially vertical control arm and a control handle coupled to the control arm. The system may also comprise a switch on the control handle, and the switch may be configured to control a function of the drive system.
An ABPI measurement system (1) includes two cuffs (10) for each ankle and two cuffs (10) for each arm of a patient. Each cuff (10) has chambers (11, 12). The four cuffs are applied to each limb (or finger or toe), each chamber (11) is inflated simultaneously to a pressure until a Pneumo Arterial Plethysmography (PAPG) signal related to the arterial flow in the limb is detected at the chambers (11). The chambers (12) are then simultaneously inflated until the PAPG signals are extinguished in each limb, the inflation of chambers (12) continuing for 10mmHg to 20mmHg above that pressure. The chambers (12) are then deflated and the pressure at which the PAPG signal returns in the first chamber (11) is recorded for each limb and this value of the pressure is used to calculate the ABPI. The ABPI is displayed or sent to a remote site.
A bed assembly (10) includes a wheeled base (12), a sub-frame (16) and mattress support frame (18). The sub-frame (16) supports a plurality of electrically operated actuators which provide for raising and lowering of the bed (10). The bed can be lowered to a first low position in which the bed frame (18) is around 38 to 45 centimetres above floor height and to a lower position in which the frame (18) is around 30 centimetres above floor height. The bed is lowered to the first height upon receipt of a first command input and can only be lowered below that first height upon receipt of a second control input distinct from the first control input. Preferably, the bed is lowered at a slower speed from the first low height to its lowermost position.
A61G 7/012 - Beds specially adapted for nursingDevices for lifting patients or disabled persons having adjustable mattress frame raising or lowering of the whole mattress frame
The invention is directed to a patient transfer system with associated patient support frames, lift carts, lifts, carts, and other accessories for use therewith. The support frames of the present invention as depicted in the exemplary embodiments are designed to: (a) provide rigidity (exoskeleton) to the human body for positioning to provide stability for purposes of transferring, lifting and/or transporting the subject via a mobile device, such as a powered lift device; (b) a male/female coupling for coupling to a tine or other carriage mechanism of a lifting device thereto for the purpose of moving or lifting the subject; and/or (c) be used as a support or frame that will interact with the body as an exoskeleton to aid with the activities of daily living.
