Definitions

  • This invention relates to therapeutic beds, which are principally of the so-called "low air loss” type and which facilitate the nursing of hospitalised patients.
  • a therapeutic bed as specified in the preamble of Claim 1 is disclosed in EP-A-0 248 537 or in FR-A-2 519 250.
  • the therapeutic bed disclosed in FR-A-2 519 250 moreover comprises a foam mattress having an indentation to receive the patient.
  • LALB's conventional low air loss beds
  • GB Patent No. 1474018 and US Patent No. 4525885.
  • Low air loss beds have been very successful clinically in nursing patients who are prone to development of pressure sores.
  • Bed-ridden and immobile patients also tend to suffer from lung congestion and have to be turned at regular intervals in order to assist drainage of fluid from the lungs. Normally, this is performed manually by nurses, who physically turn the patient at one to two hour intervals.
  • powered turning beds exist, these are primarily designed for spinal injury patients and are designed so that the patient is tightly confined. In such powered turning beds, the patient is turned slowly through an angle of up to 60 o in each direction, and the patient is wedged between blocks of foam and strapped to a firm baseboard. This tightly confined condition is found by many patients to be very unpleasant, can induce nausea and encourage the development of bed sores unless the patient's condition is constantly monitored.
  • the present invention provides a therapeutic bed which comprises the features specified in Claim 1.
  • Dwell times at the extreme point in the cycle may vary from a few seconds to 30 minutes but is preferably between about 1 and 5 minutes.
  • the operative surface of the bed is made up of a plurality of individual inflatable air sacs, which are shaped to produce a cavity corresponding to the silhouette of the patient.
  • the patient can be snugly nested in the air sacs while being supported at minimum skin contact pressures.
  • the air sacs are made partly or wholly from water vapour permeable material, which is however impermeable to liquids.
  • water vapour permeable LALB's By using such materials and ensuring that an air flow takes place within the sacs, water vapour is induced to pass into the sacs and is swept away in the air stream. In this way, the condition of the patient's skin and his comfort generally is improved.
  • the operation of water vapour permeable LALB's and the selection of suitable water vapour permeable materials is described in GB Patent No. 1474018, US Patent No. 4525885, U.K. Patent Specification No. 2141333, WO 86/06624, US Patent No. 3822425 and "Bed Sore BioMechanics", edited by R.H. Kennedy, J.M.
  • the operating means for pivoting the attitude frame may be selected from a variety of systems, e.g. inflatable air bags (which can be repetitively filled and exhausted) or hydraulic rams acting between the trolley frame and the attitude frame, such methods have various disadvantages. It has been found that the most effective operating means comprises a direct mechanical linkage between the relatively movable components, i.e. the attitude frame and the trolley frame.
  • the mechanical linkage may be a pinion drivably connected to an electric motor which is arranged to mesh with a toothed gear or quadrant, the pinion and toothed gear or quadrant being mounted respectively on the relatively movable frame components. Where the motor can be operated at low rpm, the pinion can be mounted directly on the motor shaft.
  • the electric motor may be coupled to a worm, (normally through a gear box) the worm being engaged with a worm wheel mounted on the other relatively movable component.
  • the bed has a trolley frame (1) which is fitted with ground-engaging castors (2) and supports an attitude frame (3).
  • Attitude frame (3) is supported from the trolley frame (1) by means of actuating arms (4 & 5) which can be raised and lowered separately or in unison by actuators (15 & 16).
  • actuators (15 & 16) in unison cause the attitude frame (3) to be raised or lowered in a horizontal plane while Figure 1b shows that if actuator (16) is extended while actuator (15) is retracted, attitude frame (3) takes up the Trendelenberg position.
  • the opposite movement of actuators (15 & 16) causes the attitude frame to be tilted into the reverse Trendelenberg position.
  • the attitude frame is fitted with potentiometric sensor means to determine when sac sections 22, 23, 24 and 25 (which together form the contour frame 8) are flat on the attitude frame (3).
  • the sensor means are 2 of the 3 analogue inputs shown in Figure 11. They are effectively variable resistors, one component being linked to the head or foot sections (22 or 25) and the other to the frame 3.
  • the sensors (18 & 19) are connected via a relay board to the microprocessor control board, so that the position of the sac sections can be monitored. Thus, there will be a voltage drop across the resistor whose value depends on the extent of pivoting of section 22 or 25.
  • This voltage change is converted by the microprocessor to an angular display on screen C ( Figures 9 to 11). This is important since the turning operation, which is indicated schematically in Figure 1d, should not commence with the sac sections in a fully contoured condition. However, it is generally safe to operate with the head or foot section raised by about 10 to 20 o .
  • Figure 1d shows diagrammatically the principle whereby the attitude frame (3) is pivotable about a longitudinal axis of the bed through a maximum angle in each direction of about 40 o .
  • the arm (4) at the head end (10) takes the form of an A-frame (61,61a), whose legs are attached to a pair of levers (45).
  • Levers (45) are linked to actuator (15) so that extension of the actuator causes the A-frame to rise (see Figure 6).
  • the A-frame is pivotably connected to the attitude frame (3) at (47) so that the attitude frame is pivotable on the A-frame about an axis, which extends longitudinally of the bed.
  • a drive motor (62) drives a pinion (67) which meshes with a quadrant shaped gear (64) fixed to the A-frame so that on operation of the motor, the attitude frame is tilted about the longitudinal axis of the bed with respect to the A-frame.
  • the air sacs (14) are not all of the same shape, although they are generally of a lozenge shape and are removably attached to the sections forming the contour frame (8).
  • the air sacs are shaped as shown in Figures 3A to 3C. As can be seen from the end views of these air sacs, their surfaces are profiled according to their location in the patient support surface formed by the contiguous air sacs.
  • the actuator (15) includes an electric motor (41) drivably engaging a threaded lead screw (42). To the free end of lead screw (42) is pivotably connected a lever (43).
  • Lever (43) is fixedly attached to a shaft (44) mounted in the trolley frame (1).
  • a pair of spaced levers (45 & 45a) are also fixedly attached at one end to shaft (44) and at their outer end pivotably connected to the lower end of actuating arm (4).
  • actuating arm (4) is in the form of an A-frame having legs (61 & 61a). The lower ends of the A-frame (4) are joined by a shaft (65), the ends of which are received in bearings in the outer ends of levers (45 & 45a).
  • attitude frame (3) is able to rotate about shaft (48) which comprises the longitudinal pivoting axis of the bed.
  • trunnion (56) Details of construction of trunnion (56) are shown in Figure 4A, from which it will be seen that the trunnion incorporates a universal joint (58) which enables pivoting movement of the attitude frame (3) about shaft (57) as well as limited angular movement between arm (5) and the plane within which attitude frame (3) lies.
  • Figure 4C shows the bearing located between arm (5) and lever (55).
  • compression springs (62a & b) extend between the attitude frame (3) and the cross shaft (65).
  • other means of damping or biasing the movement of the attitude frame may be employed such as gas struts in place of the springs. Only one end of the gas struts or springs is fixed so that they function only in compression.
  • a quadrant (64) is formed with toothing to form a curved rack and is fixedly attached to the A-frame (4).
  • a motor (62) is carried by a supporting plate (69) which is fixed to the attitude frame (3).
  • Motor (62) is arranged to drive a pinion (67) which is engageable with the curved rack of the quadrant (64) and the arrangement is such that with the pinion engaged with the rack, operation of the motor causes the attitude frame to turn about the axis of the trunnion (47).
  • the motor (62) includes a gear box (68) which reduces the speed of the pinion to an appropriate rate. It has been found that an appropriate speed for the pinion is about 2 rpm. In an emergency when it is desired to return the bed rapidly to the horizontal position, the pinion speed may be increased.
  • a DC electric motor is preferred for several reasons.
  • the shaft speed has a linear relationship with the applied voltage. Therefore, the rate of turning can be accurately determined and controlled by regulation of the voltage.
  • the low voltages employed make the bed electrically safe.
  • the bed can be operated by on-board batteries which makes the bed truly portable. Normally, a battery charger will be included and a rectifier for operating from a mains voltage supply.
  • a DC motor such as the "pancake" motors manufactured by Printed Motors Limited of Bordon, Hampshire, England. These motors deliver high torque at low speed, e.g. 900 rpm at 6 volts and exhibit an almost exactly linear speed/voltage relationship.
  • the pivoting speed of the attitude frame can be controlled by connecting the turning motor (62) to the central processor board via the relay board and regulating the applied voltage in accordance with the programmed turning speed (see Figures 9 to 11).
  • the motor and gear box assembly (62 & 68) are bolted onto a supporting plate (69) which is itself pivotably mounted on bracket (66) by shaft (70).
  • a push rod (71) Connected to the end of plate (69) remote from shaft (70) is a push rod (71), the opposite end of which is clamped to one end of a shaft (73) mounted in a side cheek of the attitude frame (3).
  • Shaft (73) can be rotated in a clockwise or anti-clockwise direction by pushing or pulling on rods (74 or 75) which are actuatable by levers (76 & 77), conveniently located at each side of the bed.
  • the control panel is shown in Figure 9 and is mounted on the face 80 of control box 13 (see Figure 2).
  • This includes an electrical mains indicator E, a blower switch F and a CPR lever G. Operation of the CPR lever will cause air to be dumped from the main air feed from the blower, thus causing all sacs to deflate rapidly and the bellows to deflate.
  • the CPR lever is also linked to the actuator control thus bringing the bed to horizontal.
  • the screen A is the temperature adjustment and display and shows the temperature of air passing through the sacs.
  • Knobs H are linked to the valves for air supply to the individual sections 22 to 25 and provide the control for individual pressure control to each group of sacs. However, all the air sacs can be simultaneously inflated to full blower output pressure by pulling out knob J. This is used for assisting the patient on and off the bed.
  • Light B is a warning light and draws attention to an alarm warning in the corresponding position in the display panel C, (see also Figure 10).
  • the bed includes a potentiometric tilt sensor manufactured by Penny & Giles, which senses the angle of the attitude frame (3) and provides a feed back to the microprocessor unit. This operates in the same way as the contour angle sensors (18 & 19) mentioned above.
  • the output from this sensor is the third analogue input indicated in Figure 11.
  • another type of pendulum sensor e.g. a mercury switch, may be used. In this way, the maximum angle of tilting can be preset so that the bed frame will commence turning in the opposite direction once the maximum tilt angle has been reached. A delay may be selectable so that there is a variable dwell at some point in the sequence.
  • control system for the bed is shown in the block diagram of Figure 11. From Figure 11, it will be seen that all controls, sensors and display devices are linked to the microprocessor control board, which controls the operation of all the functions of the bed.
  • the system automatically enters operating mode 1 upon power up.
  • the control system receives input from transducers which are displayed on the screen (see Figure 10).
  • Indicators to set desired pressures can be set in this mode from keypad input (101).
  • Inputs from CPR switch, Power Loss and Full Inflate are also monitored in this mode. All hand control functions which control the beds standard functions, i.e. tilt, posture and high low are available.
  • the turning parameters can be set by keypad input (101), once parameters are set they are displayed.
  • the system checks all safety switches and if found to be correct, turning can begin. While turning is in progress all inputs including CPR Power Loss and Full Inflate are continually monitored.
  • the Hand Control functions may be inhibited to allow the bed to turn safely within pre-set limits. If these pre-set limits are exceeded, advisory messages are also displayed to indicate which fault conditions exist. Alarm messages are also displayed if the various alarm conditions are met.
  • the bed can be stopped from turning or the dwell-time can be frozen to allow a nursing procedure to take place.
  • the bed can then be restarted to continue its last operation or returned to a level position.
  • the attitude frame is fitted with a circumferential D-section inflated tube.
  • This tube is connected to a pressure sensitive switch which is activated when the tube presses against an obstruction and therefore increases the pressure in the tube.
  • the switch sends a signal to the microprocessor which in turn causes the turning motor to reverse and thus move away from the obstruction.
  • the display panel will indicate the presence of an obstruction.
  • an infra-red detector may be used.
  • the control system includes a third mode called the maintanance or service mode.
  • the microprocessor is programmed to check the operating functions of the bed and to indicate in the display panel A any malfunctions.
  • control means includes an output port and an ancillary printer or recording device (e.g. a tape cassette).
  • an ancillary printer or recording device e.g. a tape cassette. This enables the clinician or nurse to print out from the microprocessor store, data concerning the sequences which the bed has performed, e.g. over the last few hours or days and provides a record of the treatment.
