Abstract
Description
- This invention relates to improvements in evacuation restraints of the type suitable for positioning under the mattress of a bed in a hospital or other institution housing bed-confined persons.
- In our Australian Patent No. 536070 (AU-B 62281/80) we have described an improved evacuation restraint which materially improved the securement of bedridden patients for evacuation purposes. In using evacuation restraints embodying the above invention, the mattress supporting a bed-confined patient is utilised to minimise the disturbance of the patient and to protect the patient during the evacuation procedure.
- Further consideration of evacuation procedures has shown that it is advantageous to be able to slide the restraint-confined mattress along the floor, over obstacles or down stairs. The restraint described in our earlier patent has been found to be not entirely suitable for that purpose even though it offered a material improvement over the previously known restraints in the manner in which it confined a patient within a mattress.
- To protect restraints of the above type against soiling and to enable it to be accessed in a standard manner to minimise delays in the event of an emergency, the restraint is desirably housed in a plastics envelope of the type described in Australian Patent AU-B 34433/78 (U.S. Patent No. 4,186,453). However, in using packages of this type it has been found that access to the pull handles by means of which the envelope is opened to gain access to the restraint straps requires the mattress to be lifted to an excessive extent whereby the patient may be undesirably disturbed. Furthermore, the package described in the above patent is not entirely convenient to handle during manufacture, marketing and storage prior to use and the cost of manufacture of such packages is relatively high.
-
- It is an object of the present invention to provide an improved evacuation restraint in which the shortcomings of the prior art restraints discussed above are at least ameliorated. It is the secondary object of the invention to provide a simplified packaging envelope for such evacuation restraints.
- Accordingly, the invention provides an evacuation restraint comprising a generally rectangular base sheet (1) of strong flexible material, a generally rectangular support member located centrally of said base sheet and joined thereto on top of said base sheet, said support member being formed of lightweight non-bulky material having greater rigidity than said base sheet being capable of deformation transversely of the support member, said base sheet extending substantially from either side of said support member to enable the base sheet in use to envelop a patient to be evacuated, strap members secured at least to said base sheet and extending from the sides of the base sheet, said strap members including means for connecting opposite strap members together at at least two longitudinally spaced positions, and strap members extending from at least one end of said base sheet by means of which the restraint may be manipulated during evacuation procedures, said support member providing with said base sheet a smooth relatively rigid base on which the restraint may slide during evacuation procedures.
- In a preferred form of the invention, the restraint is enclosed within a protective envelope having means for gaining access to said base sheet and said straps. Preferably the protective envelope includes a base portion and a top portion, said top portion having one or more means for enabling removal of the top portion from the base portion. The top portion is preferably made from a suitable transparent plastics material and the means for enabling access comprises a line of weakening formed in said top portion and one or more gripping handles or tabs secured to said top portion by means of which the top portion may be torn open to expose the base sheet and straps.
- The support member preferably comprises a sheet of lightweight corrugated board which is most preferably formed from plastics materials. The board is preferably capable of being folded along at least two transverse lines so that the evacuation restraint and protective envelope may be folded into a more convenient size for marketing and storage purposes.
- One presently preferred form of the invention will now be described with reference to the accompanying drawings in which:
- Figure 1 is a perspective view of the restraint in the unfolded position showing a mattress and patient ready to be enveloped;
- Figure 2 is a sectional end elevation of the restraint of Figure 1;
- Figure 3 shows the restraint in use;
- Figure 4 shows the restraint partly folded ready for packaging;
- Figure 5 shows the restraint packaged in its envelope;
- Figure 6 is a perspective view of the restraint partly opened; and
- Figure 7 shows the packaged restraint in the folded condition.
- Referring firstly to Figures 1 and 2 of the drawings, the restraint embodying the invention will be seen to comprise a generally
rectangular base sheet 1 of flexible fabric, such as polyester, which has been treated to be fire resistant, water resistant and relatively friction free, for example by coating or impregnation with Teflon (registered trade mark). A relativelyrigid support member 2 is secured centrally to thebase sheet 1 by sewing or by adhesive. In the present case, thesupport member 2 comprises arectangular sheet 3 of corrugated board formed from plastics material, such as corrugated board sold under the trade mark Corflute, to each end of which smallrectangular pieces rectangular portion 3 has its corrugations running longitudinally while thesmaller portions central portion 3 is formed withfold lines smaller portions - Referring still to Figure 1 of the drawings,
webbing straps base sheet 1. Thestraps base sheet 1 and terminate in loops L by means of which the restraint may be handled during an emergency.Strap portions strap 12, 13 a short distance (e.g. about 6 cm) from the ends of thesheet 1 to a point of attachment to the end of thesheet 1 at the edge of eachsmaller portion base sheet 1 at 14 and is formed insmall loops side straps webbing 21 extends tranversely across thesheet 1 near its lower end and is attached to theside straps webbing 21 defines aloop 19 at the right hand side of thesheet 1 and has awire loop connector 23 of known construction secured thereto at the other end. Afurther strap 20 is attached to theloop 15 and has a similar adjustablewire loop connector 22 attached thereto. Theconnectors loops - To enable the restraint to be conveniently stored in a protective package, the side portions of the
base sheet 1 and therestraint straps support member 2 and are then folded back on top of the inwardly folded portions. The end portions, includingportions straps additional gripping loops base sheet 1, as shown in Figures 3 and 4 of the drawings. Theseloops - Referring now to Figures 5, 6 and 7 of the drawings, the protective envelope for the restraint will be seen to comprise a
base portion 27 of suitable plastics material which is either treated with a material which causes the material to be slightly sticky, or "non-slip" in character, or is made from a "non-slip" plastic to retain its position under a mattress in use and so that thebase portion 27 tends to stay in position as the restraint is removed therefrom. A clear plasticstop portion 28 is secured by heat sealing around the periphery of thebottom portion 27 and acentral panel 29 of thetop portion 28 is removable by tearing along a weakeningline 30 formed during the heat sealing process. To assist in the removal of thepanel 29,handles 31 are heat welded to each corner of thepanel 29 at either end, for example, as shown in Figure 5 of the drawings. For instructional purposes, one or more of thehandles 31 may be printed with a replica of a hand to show how the handles are to be gripped when the panel is to be removed. Each handle is secured along a substantial portion of each corner of thepanel 29 to ensure that the panel will tear away along theline 30 when thehandles 31 are pulled. - For transport and storage purposes, the package restraint is able to be folded along the
lines - In use, the packaged restraint is stored centrally under the mattress M supporting a bed-confined patient P. In the event of an emergency, the operator performing the evacuation reaches under the mattress and grips one or more of the
handles 31 to tear thepanel 29 from the protective envelope along the weakeningline 30. The loops L at the ends are pulled and thediagonal portions portions sheet 1. As shown in Figure 6, access is thereby gained to thehandle 25 and the folded edges of thebase sheet 1 may be moved by pulling thehandles loops straps connectors loops straps - Since the
support member 2 provides a relatively rigid flat surface covered by thebase sheet 1, the restraint is able to slide over floors, stairs or obstructions, assisted by the low-friction coating on thebase sheet 1. Furthermore, since thebase sheet 1 almost encloses the mattress M and patient P, additional protection is provided in the event that fire or water are encountered. Thus, the restraint embodying the present invention provides a significant advance over the prior art restraints and provides even further advantages when contained in the improved protective envelope described above.
