Description

WO 02/26188 PCT/GBO1/04267 FLEXIBLE HEAD SUPPORT This invention relates to a fully flexible support assembly for the head, to assist with the non-invasive 5 positioning requirements of patients in a clinical setting, in particular for prone positioning. It is known to have specially shaped cushions/pillows constructed of foam or gel to support the head, such cushions are used primarily in the 10 rehabilitation and physiotherapy fields. Also, prone positioning can be achieved on most types of support surface with the head turned to one side. Known inflatable systems include a head deflate function which improves access around the head by deflating the cells 15 directly underneath the patient independently of the rest of the system. The head drops into the hole created and is then supported using standard pillows. Head management systems include placing the patient's head between two cushioned side clamps to 20 maintain spinal alignment during periods of rotation. Similar head support accessories exist in the physiotherapy and operating theatre environments for carrying out ENT, neurosurgical, oral and ophthalmological procedures. 25 The present invention seeks to make improvements. It is an object of the present invention to facilitate effective nursing management of the head and face by optimising visual and physical access required for clinical interventions, to provide universal 30 adjustment to support most patient anatomies and to provide an effective pressure reducing/relieving contact surface for the head and face.

WO 02/26188 PCT/GBO1/04267 2 Accordingly, the invention provides a head support apparatus when positioning a person in a prone position comprising a base having an upstanding post, the post supporting a head support means, the head support means 5 including a pressure reducing contact surface for supporting a face of a person. Advantageously, the invention combines the anatomical positioning requirements of a head support for a person in a prone position with a pressure reducing/relieving support 10 surface for the head and face. Preferably, the head support means has a self stabilising base slidable under a support surface. More preferably, the post is adjustable to allow for multiple axis adjustment and additionally, quick release for ease 15 of use and emergencies. Preferably, the head support means is adjustable laterally, to allow for positioning flexibility. Preferably, the pressure reducing contact surface is provided by an inflatable bladder(s) inflatable and deflatable through predetermined cycle 20 times for pressure relieving. Preferably, the bladder(s) is in the shape of a ring and more preferably is made of clear material to allow nurses and carers to see the head resting upon the bladder. Overall, the invention provides the detailed 25 anatomical positioning requirements for a head support during proning to optimise visual and physical access to the head/facial area whilst minimising the risks of pressure damage to the patient. An embodiment of the present invention is described 30 below, by way of example only, with reference to the accompanying drawings in which: WO 02/26188 PCT/GBO1/04267 3 Figure 1 is a schematic diagram of the head support installed on a support surface; Figure 2 is a schematic diagram of the head support system; 5 Figure 3 is a side view of Figure 2 showing the mounting arrangement of the head support on the base; Figure 4 is a back view of Figure 3 showing the head support carriage mechanism; and Figure 5 is a plan view of the head support tray. 10 Referring to Figure 1, the head support assembly 10 is used with the base 11 sliding under a support surface 1 to be used for proning. As shown in Figure 2, the base 11 has a central supporting post 12 incorporating a slide 13, rack 14 and carriage stop 15. As shown in Figure 4, a 15 head support frame 16 is mounted onto the post by a head support carriage 21 engaging the sides of the slide 13 and being locked into position by the carriage stop 15. The carriage mechanism 21 allows for multiple axis adjustment of the frame 16 and delivers a safe method for 20 quick release in the event of an emergency situation. The slide 13 delivers a smooth method of vertical adjustment. A head support tray 18 slides onto the two tubes 17 of the head support frame 16 and is locked into position by locking mechanism 19 (see Figure 3). A safety catch 20 25 prevents the head support tray from being pulled off the ends of the tubes 17. An inflatable pressure reducing ring 23 is mounted on the head support tray 18 by straps 24 with hook and loop fastening means to provide a static or alternating support surface for the user's head. 30 Contact points along the surface of the pressure reducing ring 23 are protected by fitted pads 25 designed to improve comfort levels for the user. The pressure WO 02/26188 PCT/GBO1/04267 4 reducing ring 23 is clear and can comprise a multi channel air bladder to allow for alternating inflation and deflation through specified cycle times of the individual chambers to provide pressure relief, if 5 desired. The tray 18 and the pressure reducing ring 23 are adjustable to accommodate differing widths and depths of head sizes (see Figure 5). The head support assembly can be used with any 10 support surface where the head requires some form of artificial support. The structure is modular and easily dismantled for servicing and cleaning requirements. The visual and physical access to the users head and facial area is maintained at all times to allow for the 15 safe management of lines and tubing which may be associated with the users clinical condition. The lightweight construction allows the head support assembly to be used independently for positioning requirements of the head in a range of specialist and non 20 specialist fields. The structure is self stabilising and will work on most bed frames with the dedicated support system, but can also be removed for use independently.
