BACKGROUND AND SUMMARY OF THE INVENTION This invention relates to an improved positioning aid for supporting, restraining and/or immobilizing a portion of the body of a medical patient as long as may be needed for conducting radiography, therapy, surgery, patient transport and the like.

Vacuum-actuated positioning aids consisting of a flexible impervious bag containing small particles which consolidate into a rigid mass when the bag is evacuated are known in the art. See, for example, U. S. Pat. No. 3,212,497 to Dickinson.

It is an object of this invention to provide a vacuumactuated positioning aid of an improved construction. An important object of this invention is to devise a positioning aid of the general type described which is readily formable into any of varying configurations and yet is so constituted as to provide a higher degree of form stability upon evacuation than is obtainable with prior positioning aids. Additionally, it is an object to provide an improved positioning aid capable of assuming and rigidly maintaining minute variations of contour by corresponding arrangements and rearrangements of small spherulic beads. To such ends, the invention includes charging the bag with spherulic beads within a predetermined general range of sizes and, within that range, assuring that substantial proportions of the total are respectively each of materially different sizes. For practical optimum results several sizes are contemplated and the proportions of beads in the lower and mid-range sizes should be substantially greater than that of beads at the high end of the range. Mobility of the bead to conform to minutely varying shapes and stable interfit (both bead-to-bead and bead-to-bag) with uniform stress distribution among the beads are materially improved over positioning aids containing beads of substantially equal size.

Another object hereof is to improve the compartmentation of a positioning aid bag with respect to cooperative distribution of the masses of beads in the respective compartments. More particularly, it is an object to provide a simple bag construction wherein the compartments may be only partially filled with beads so that before evacuation the bag is highly flexible and readily conformable to various shapes and after evacuation does not present difficulty with lack of solidity due to void spaces in the partially filled compartments. To this end, partitions extending obliquely between and interjoining opposing walls of the bag held assure mutual reinforcing overlap of the bead masses in adjacent compartments.

Still another object hereof is to provide a safe, reliable, inexpensive and readily operable vacuum valve for positioning aids of the types described. Moreover, it is an object to achieve such a valve which will not scratch or injure a patient and which may be made without exterior metal parts that can create sparks in a surgical operating room. A related object is to provide such a valve which can be opened manually by pinching it in a certain manner. which will automatically become and remain firmly sealed against loss of vacuum in the bag until so operated, and which is so constructed as to preclude accidental operation by reason of normal pressures and stresses applied to it in the handling or use of the positioning aid.

DETAILED DESCRIPTION OF THE INVENTION Referring to FIGS. 1 3, there is shown one embodiment of the positioning aid of this invention. It comprises a generally rectangular, air-tight bag 1 of flexible, impervious material, containing a charge of elastically deformable spherulic beads 2. The bag is equipped with a self-closing valve 3. The interior of the bag is divided into three compartments by two partitions 4 extending lengthwise of the bag and obliquely between the bag walls. Each compartment contains a fraction of the total charge of beads. So that the aid is readily conformable to various portions of a patients body, each compartment is only partially filled with beads. Screened openings 5 are Provided in the partitions so that air can flow between compartments while the beads cannot. The partitions maintain the beads more or less evenly distributed throughout the bag. As shown in FIG. 2a, orientation of the partitions obliquely to the bag walls reduces the effective thickness of each compartment along the partitions and thereby assures a more even distribution of beads in each compartment when the bag is so positioned that the beads tend to accumulate along the partitions.

FIGS. 3 6 show the details of a self-closing valve which is especially preferred for use in the positioning aid of this invention. Except as indicated, all of the valve parts are made of the same soft, flexible material, such as polyvinyl chloride. The valve consists of a cylindrical body 6 having an integral plug 7 secured to one end and the circular valve base 8 to the other, the valve base being sealed to the inner side of the bag wall 9. An inner cylinder 10 having one flat side 11 (FIG. 5) extends within and is enclosed by the valve body. The inner cylinder is provided at one end with an integral circular lid 12. The lid is hinged to the flattened part of the periphery of the inner cylinder so as to be moveable thereabout. The other end of the inner cylinder is joined with the valve base 8 and is in communication with the interior of the bag through an opening in the base. A layer of fine mesh wire screen 13 and a layer of loosely woven cloth 14 are positioned over this hole and are secured to the base. The screen and cloth prevent the beads from being drawn from the bag when a vacuum is applied to the valve.

In FIGS. 3 and 4 the valve is in its closed position with the plug 7 being inserted in the end of the valve body and the hinged lid 12 abutting against and closing the free end of the inner cylinder. When the positioning aid is to be evacuated, plug 7 is removed from the opening in the valve body (FIG. 6) and the valve is then connected to a vacuum source. Application of the vacuum causes the pressure on the outer side of the lid to become less than on the inner side and the lid moves to its open position as shown in FIG. 6. When the externally applied vacuum is interrupted, the lid 12 automatically returns to its closed position because of its own resilience and the greater pressure on its outer side. The plug 7 is then inserted into the valve body providing a second seal.

When it is desired to release the vacuum within the positioning aid, the plug 7 is removed and the square, raised areas 15 on the outside of the valve body are squeezed with the thumb and index finger. Sufficient pressure is applied to deform both the valve body and the inner cylinder, deformation of the latter causing the lid 12 to open (as shown in FIG. 6), causing the vacuum to be released. The plug 7, when inserted in the valve body, prevents the vacuum from being released even if the valve body and inner cylinder should be accidentally compressed sufficiently to open the lid.

The valve of this invention is especially dependable and convenient to operate, provides a substantial margin of safety against accidental release of the vacuum within the bag and, because of its soft, flexible construction, cannot injure the patient. Furthermore, the valve can be inexpensively manufactured as an integral unit, except for the screen and cloth, by well-known injection molding techniques.

The material from which the bag portion of the aid of this invention is manufactured should have good flexibility, durability and air-tightness. Suitable sheet materials include soft polyvinyl chloride, nylon, polypropylene, polyethylene, tetrafluoroethylene resins, urethane, copolymers of ethylene and vinyl acetate, soft ABS. resin acrylic esters, silicon rubber, and mixtures of polyvinyl chloride and synthetic rubber. Plasticizers, flame retardants, pigments and lubricants can also be included. A preferred sheet material comprises a mixture of from 70 to 80 parts by weight of polyvinyl chloride and from to parts by weight of synthetic rubber. A 75:25 ratio is especially preferred. Sheets of this composition exhibit excellent flexibility and a high coefficient of friction. Flexibility is of importance because the bag must conform well to the shape of a patients body. The high coefficient of friction of the bag material increases the friction between the beads and the bag wall which in turn increases the stability of the rigid structure formed when the positioning aid is evac uated. 5 The beads used in the positioning aid of this invention must be sufficiently rigid to withstand the stresses which result when they interengage upon evacuation of the bag. The beads must also have a high mechanical strength so that the aid can be repeatedly used without accompanying attrition or fracture of the beads, and should also be elastically deformable such that when the bag is evacuated they can move freely into close engagement to thereby form a stable, rigid structure.

Beads of expanded plastic materials, such as polystyrene and polyvinyl chloride, are preferred because of their high mechanical strength, elastic deformability and low specific gravity. Beads of expanded polystyrene are especially preferred. The expression specific gravity is intended herein to mean a true specific gravity. Thus, when such beads are made hollow, the specific gravity of the bead is represented by its weight divided by its total volume including the hollow spaces therein. According to the invention, the specific gravity of bead should be in the range of from about 0.1 and about 0.6. Such values are readily attainable with foamed synthetic resins, although other materials can be used for granules when they have a low specific gravity in the range specified above and satisfy the mechanical strength and elastic deformability requirements. A specific gravity of foamed synthetic resin materially less than 0.1 is only achievable when the resin is excessively foamed, and the resulting beads are soft and not effective for the purpose of the invention. When the specific gravity materially exceeds 0.6, the formability of the aid, its form stability when evacuated and its transparency to X-rays are diminished, and the aid cannot be conveniently handled because of its increased weight.

In order to insure that the positioning aid fits well to the patient and remains stable when evacuated, the beads should be from about 1 to about 5 millimeters in diameter. Beads which are uniform in size and shape can be used, but it has been found that an aid containing a mixture of substantial portions of beads of at least two materially different sizes within the indicated range provides more uniform and stable support to the patient than does an identical aid containing beads which are all of one size. Preferably, the beads are of differing sizes distributed across the range of from 1 to 5 millimeters, with sizes in the lower and middle portions of this range predominating. The following is an especially preferred distribution of bead sizes:

Diameter (mm.) by Volume l 20 man-aw and remained below half an atmosphere pressure after 3 days of use. It was found that repeated use had a tendency to maintain thevacuum over an increasing time period. Also, expanded plastic beads which has been kept in storage for an extended period, for example 1 month, were charged into the positioning aid, the aid maintained a usable degree of vacuum over an increased period as compared with a corresponding aid in which freshly prepared beads were charged. Therefore, it should be understood that the particular pressure to which the interior space of the positioning aid is evacuated depends upon various factors, including the material for the bead and bag body aswell as the particular applications intended. It has been found that the positioning aid of the invention is operable with its internal pressure below half anatmosphere pressure, eventhough it should be obvious that the lower the pressure, the better the aid maintains its form.

FIGS. 7 and 8 show two other useful shapes in which the positioning aid of this invention can be constructed. The valves 3 and partition walls 4 in these two embodiments are the same as in the embodiment discussed above. The aid shown in FIG. 7 is particularly useful for supporting the torso of a patient in a normal lateral po-- sition, one shoulder of the patient being situated in the recess 16 on one end of the aid and sides of the aid 17 being folded upwardly along the patients front and FIGS. 10a l0d'illustrate the preparation of a recurvature bed in dorsal decubitus using a positioning aid according to this invention. The positioning aid 19. is placed on a board 20 and is first evacuated so as to be essentially rigid .(FlG. 10a). Then a hard pillow 21 is inserted between the rigid aid and board at a location where it is desired to provide recurvature .(FIG. 10b). A patient is caused to lie down on the aid in dorsal decubitus (FIG.10c) and air is allowed to enter the interior of the aid through the valve (not shown). The aid thereby becomes limp so that the body of the patient sinks into the aid, whereupon parts of the aid are fitted around the shoulders and waist of the patient (FIG. 10d). After any required correction of the patients position, the valve of the aid is'connected to a vacuum pump to evacuate theaid. It is also possible to evacuate and solidify the aid during the interval of correcting the patients position. The purpose of initially evacuating the aid is to prevent beads from being displaced away from the space directly below the patients body when the aid is limp. However, if partition walls are provided in the interior of the bag body as described previously, the initial evacuation is unnecessary.

In order to examine the state of a spine and blood circulation during the dorsal fixation on the positioning aid, a patients spinal curve (FIG. 11) and back pressure (FIG. 12) were measured for five cases indicated below.

It will be noted that the curve (b) has alower backward curvature of thoracic vertebra (B/oz) than curve (a), but the point (7), the transition from backward curvature of the thoracic vertebra to forward curvature of lumbar vertebra, remains unchanged. In the curve (0), the backward curvature becomes even less and the point of transition shifts upwardly. All of five cases showed similar results. It is known that backward curvature of spinal curves measurcd in dorsal and ventral decubitus is less than that in standing position and that the point of transition measured in standing position remains'unchanged in dorsal decubitus, but shifts toward the head in ventral decubitus. This fact indicates that the curve (b) represents'physiological dorsal decubitus, while the curve (c) physiological ventral decubitus. Thus, it will be appreciated that dorsal fixation by means of the positioning aid of the invention maintains the physiological curvature fairly well so that a patient does not suffer from pain due to forced fixation.

FIG. 12 shows pressure per 20 cm -on a patients dorsal surface with an ordinary mattress (broken lines), plaster of Paris bed (clain lines) and the positioning aid of the invention (solid lines). An electro-manometer was used to measure pressure at 15 points, namely, five points on the dorsomedian line and five points on the right and left scapular lines, as indicated below.

It will be noted that the positioning aid according to the invention can be applied to many fields of medical treatments and diagnosis. A patient supported and restrained by the positioning aid can be X-rayed while the portion of his body to be examined is covered by the aid. Little or no shadowing influence is observed in the X-ray photograph.
