Application June 5, 1953, Serial No. 359,817

9 Claims.

This invention relates to .a restraining device. It deals, more particularly, with a device adapted to securely hold a delirious, insane or unruly patient, in a bed so as to prevent the patient from injuring himself or others.

There have been a number of restraining devices employed for the purpose indicated. However, these devices have usually been of such a nature that they do not afford easy adaptability to beds of varying dimensions, or permit rapid. restraint of the patient regardless of his size, or these devices are such that they exert great pressure upon the patients limbs and cut off the blood circulation with resulting injury to the blood vessels.

An object of this invention is to provide a restraining device which is laterally and longitudinally adjustable relative to beds of varying dimensions in order to restrain patients while permitting their complete comfort.

Another object of this invention is to provide a restraining device wherein a variable degree of restraint of the patient is obtained so that any one of the limbs may be entirely raised above the surface of the bed without permitting flexure thereof.

A further object of the invention is to provide a restraining device which is easily and speedily applied over any one of the limbs of a patient and which cannot be released by the patient.

Still another object of the invention is to provide a restraining device which will permit a controllable degree of movement of the limb of the patient around which it is applied.

Yet another object of the invention is to provide a restraining device which may be adjusted relative to the limb of a patient without thereby permitting motion of the latter.

Still a further object of the invention is to provide a restraining device which when applied to any one of the limbs of a patient affords a uniform distribution of the pressure exerted by said device over the surface of said limb.

Yet a further object of the invention is to provide a restraining device which is compact, easy to operate, and which may be stored within a minimum of space.

With the above and other objects in view, the invention will be hereinafter more particularly described, and the combination and arrangement of parts will be shown in the accompanying drawing and pointed out in the claims.

Reference will now be had to the drawing, wherein like reference numerals designate corresponding parts throughout the several views, in which:

Fig. 1 is a perspective view showing the re-' straining devices made according to the invention being employed for holding a patient in the supine position on a bed.

Fig. 2 is a fragmentary front elevation of a bed and showing two of the restraining devices mounted thereon and around the limbs of a patient shown in phantom lines.

Fig. 3 is a plan view of one of the restraining devices constructed according to the invention.

Fig. 4 is a sectional view of the portion of the restraining device which is used to adjust the tension exerted on the limb of a patient.

Fig. 5 is a transverse sectional view taken on line 5-5 of Figure 4.

Fig. 6 is a transverse sectional View taken on line 66 of Figure 3.

Fig. 7 is an enlarged view of the shackle illustrated in Figure 6 and showing the details of the latch and release mechanism thereof.

Fig. 8 is a perspective view of another species of sleeve which may be substituted for the sleeve of the restraining device shown in Figure 3.

In the illustrated embodiment of the invention, the bed includes the usual head and foot sections and their corner posts l0 and connecting side rails H. The bedding including the mattress is designated at !2 in Figure l of the drawing.

Each restraining device 20 comprises a limb engaging pad I 3 formed of sponge rubber or any other suitable soft material which is secured to or within a covering M of suitable material such as Dacron and the like or any textile fabric. The covering I4 is provided at opposite edges with slide fastener tapes [5, l6 and the slide fastener is of the type in which the time may be completely disengaged. The engagement of the tape l5 at the lowermost end thereof with a socket at the bottom end of the tape I6, permits the operation of the slide I! by the movement of the handle 18 connected thereto to bring the opposite sides of the covering M in juxtaposition and to form a tubular sleeve.

Referring more particularly to Figs. 6 and 7, the covering It is slightly spaced from pad I3 by a snap-closing shackle Hipositioned between said covering and said pad. The pad may additionally be provided with a groove (not shown) in order to facilitate positioning shackle l9 between the covering and the pad. The shackle I9 is provided with a hooked extremity 2| adapted to co operate with a pawl 22 pivotally supported to the opposite extremity 23 of the shackle. A spring I 2G is adapted to maintain pawl 22 in the position wherein it is engageable with extremity 2| and pressure upon the intermediate portion of spring 24 affords disengagement of pawl 22 from extremity 2i when it is desired to open shackle IS. The shackle I9 is also provided with a neck portion 25 which connects the former with housing 25, see Figures 4 and 5.

The housing 26 is provided with e, longitudinally extending groove 21 substantially U-shaped in cross-section, and with a transverse bore 28 intersecting the groove 21. Bore 28 is adapted to receive a bolt 29 provided with a worm gear section 30 intermediate the ends thereof. A helical spring with a substantially round section is designated by reference numeral 3|. Spring 3| is snugly and slidably received Within groove 2? at the bottom thereof in order that the coils of the spring mesh with worm gear section as, see Figures 4 and 5. Upon rotation of bolt 29, the spring 3| is longitudinally displaceable in either direction. However, the pitch of the coils of spring 3| and of the threads of worm gear section 36 is selected so that tension or compression exerted upon the spring 3i will not be effective to longitudinally displace the latter. Therefore, spring 3| is longitudinally displaceable only upon operation of bolt 29 in either direction. Spring 3! is thus retained within groove 27 by the threads of worm gear section 38 while one end of the spring 3| is secured to one extremity 34 of a belt 32 having conventional means 33 for adjusting the length of the latter. The opposite extremity 35 of the belt 32 is secured to a clamp 36 removably and adjustably secured to any one of side rails I l by screw means 31 which operates in a known manner.

There may be provided intermediate each pair of shackles 15, of each restraining device 2!], and

on a transverse member '33 extending across the L bed elements 39 and 39 of snap fasteners 39a and 3917 which cooperate to maintain adjacent pairs of restraining devices 20a and 20b in predetermined spaced relationship.

In operation, a plurality of restraining devices 20 are mounted on the connecting side rails ll of the bed, substantially as shown in Figure 1. Although the invention has been principally described as useable in conjunction with a bed it is obviously useable with any article of furniture having rails and the like; e. g. chairs. The patient is made to lie on the bed and the restraining devices are applied to the corresponding limbs by first closing the shackles over the limbs and subsequently leisurely shutting the slide fastener elements. Subsequently, the shackles l9 may be released, when desired, by simply applying pressure upon spring 2d. The adjustable yielding means comprising elements 26 through 30 may be adjusted at any time so that the patient is allowed a slight degree of movement of his body or of his limbs and he will thereby be more comfortable. The transverse members 38 may, if desired, extend over the body of the patient so as to simultaneously prevent movement of the body and of the limbs of the patient.

The restraining device may be adapted to permit intravenal injections by providing a cut out Within limb engaging pad [3 and covering M. An example of this modification is described infra.

Referring more particularly to the species shown in Figure 8, a portion of the limb engaging pad (3 and of coverin [4 is cut away and a pair of slide fasteners similar to the slide fastener already described has been substituted for the latter. A bar 38" of substantially rigid material interconnects in an obvious manner the extremities of the sleeve whereby the rigidity of the latter is insured. The bar 38 is located between the covering [4 and the pad [3 so that it will not abut directly against the limb of the patient. Apart from these modifications, the structure of the sleeve, shackles, tension adjusting means, and belts is identical to the structure of the restraining device shown in Figure 3. The sleeve of Figure 8 has been cut away in order to permit the application of hypodermic needles and the like upon the limb of the patient whenever such is deemed desirable.

Although a plurality of embodiments of the invention have been described and illustrated, it will be understood that various changes and modifications can be made therein without departing from the spirit of the invention as defined by the appended claims.
