Definitions

  • the present invention relates to the procedure for resuscitating persons who are victims of asphyxia (by inhalation of water or gas or otherwise), or shock, according to which the affected person, supported in a prone position, is rocked about a transverse horizontal axis so as to tilt his body alternately head downward and feet downward.
  • the abdominal Organs are displaced by gravity toward and away from the chest, pulling and pushing the diaphragm back and forth, thereby expelling water or asphyxiating gases, and causing the lungs to inhale and exhale.
  • gravity propels the blood in arteries and veins alternately in opposite directions.
  • the fulcrum support is a framework having a wide base and a single cross bar at the top.
  • Conventional collapsible stretchers are used with this support, the side bars of the stretcher extending over the cross bar of the support and being made fast thereto so that they will not slip when the stretcher is tilted at a steep angle.
  • the unconscious victim In using that apparatus, the unconscious victim must be lifted a height of three or four feet in order to be placed on the stretcher, which requires the cooperation of three or more people to hold the body straight while lifting it, and to steady the stretcher; and care must be taken to locate the body on the stretcher with its center of gravity as near as possible to the cross bar.
  • the fabric When the body is placed on the stretcher the fabric sags under the weight of the body, but the cross bar prevents sagging of the mid length of the stretcher, making a ridge which presses into the abdomen of the person lying on the stretcher and impedes those movements of the organs which produce compression and expansion of the lungs.
  • Another type of equipment which is used on boats, includes a basket stretcher to which, at mid length, a cross bar is permanently connected, and the ends of the cross bar are designed to be placed in sockets at the upper ends of two rigid supports which are secured permanently to the deck of the boat.
  • the victim of drowning is lashed in the stretcher when pulled out of the water and the stretcher is then mounted on the uprights. In that procedure it happens more often than not that the body is placed with its center of gravity at some distance from the cross bar.
  • One of the objects of this invention is to provide a supporting means with which a stretcher can be connected for tilting movement after the victimof asphyxia or shock has been placed on the stretcher, and with respect to which the stretcher bearing the victim can be readily adjusted so as to bring the center of gravity directly over the fulcrum axis, without disturbing his position on the stretcher.
  • Another object is to furnish a demountable stretcher support which can be stowed away in a small space when not in use and can be erected for emergency use almost instantaneously.
  • a further object is to produce such apparatus at a cost moderate enough to enable units to be procured by municipalpolice and fire departments, the proprietors and custodians of bathing resorts, camps and other resorts, hospitals, etc.
  • Apparatus embodying the invention comprises a portable supporting structure which, in its preferred form, can be collapsed into small compass and instantly expanded for use, and stretcher connectors pivotally connected to such support and having means for receiving the longitudinal side members of a stretcher at any one of a number of points along the length of such side members and securing the stretcher against longitudinal displacement. It further comprises means for rapidly fastening the body of a victim to the stretcher so that it cannot slip when the stretcher is tilted and in such a manner that the circulation is not restricted in any part of the body. It also includes a means for showing when the stretcher applied to the connectors is horizontal and measuring the angles of tilting movement in each direction from the horizontal position.
  • Fig. 1 is a side elevation of the preferred embodiment of the present invention showing the supporting structure and a stretcher in assembled relation;
  • Fig. 2 is an end view of the same as seen from the right hand side of Fig. 1;
  • Fig. 3 is a side view of the supporting structure collapsed in condition for stowage
  • Fig. 4 is a side elevation of the central portion of the equipment shown in Fig. 1 and depicted on a larger scale;
  • Fig. 5 is a cross section taken on line 5--i5 of Fi 4;
  • Fig. 6 is a plan view of the stretcher connector shown in Figs. 4 and 5;
  • Figs. '7 and 8 are, respectively, a side elevation and a plan view of the combined apparatus show- .ing theposition in which a person is placed on the stretcher for resuscitation and means for holding his body thereon;
  • Fig. 9 is a cross section of the stretcher and body holding means taken on line 99 of Fig. '7.
  • the supporting structure comprises four legs and an axle rod, on which are pivotally mounted two clips or stretcher connectors.
  • the legs are connected in ,pairs, each pair being composed of a single length of tubing bent into a formappropriate for the purpose.
  • the legs 10 and l I. shown in Fig. 2 are connected at their lower ends by a cross member 12.
  • These legs and the cross member are formed of a single piece of tubing bent at locations equidistant from the mid length to provide foot portions 13 and H3, between which the cross member ['2 extends, and the cross member is bent so that its mid portion is offset upwardly from the line connecting the foot portions.
  • This ,formation causes the contact of the legs with the ground or a floor to be concentrated at the foot portions I3 and i4 and .located at a definite distance apart.
  • the cross member I2 connects the foot portions rigidly, preventing them from spreading apart 'or being brought nearer together. By reason of its upwardly ofiset bend it is removed from any such contact with an under surface as to permit sidewise rocking of the structure, but at the same time it is so near to the line of the foot portions that it affords a widening base on soft ground or sand into which the foot portions may sink.
  • the legs I and H are inclined slightly toward each other, and near their upper ends are bent so that their end portions are parallel.
  • the legs of the other pair, one of which is designated IS in the drawings, and a connecting cross member, are identical with the legs and cross bar formation above described.
  • the connector I9 is shown in detail in Figs. 4, and 6. It is made with a base portion having a flat upper surface and two -at the outer side of the connector. Such lip and web are parallel to one another and are in planes perpendicular to the axle. They are spaced apart, providing a channel enough wider than the thickness of the side bars of all standard stretchers to receive any such side bar flatwise on the upper surface of the connector base.
  • the Web 24 contains slots 25 and 26 which are separated from one another by a distance prescribed by considerations later explained, are located at opposite sides of the median line of the connector (the line perpendicular to the connector base which passes through the pivotal center of the lugs 21 and 22)., and are inclined upwardly from their outer ends toward such median line.
  • Spurs 2'! and 28 are mounted in the connector base near the opposite ends thereof, being provided by the pointed ends of screws which are threaded through the base so as to be adjustable and are secured by lock nuts 29.
  • the connector 26 is identical with the connector 19 as thus far described, and is disposed in symmetrically opposite position on the opposite end of the axle i9 with its lugs embracing the end fittings of the leg I l and the leg corresponding thereto which is united with leg IS.
  • the parts thus described are assembled by overlapping the end fittings of the two pairs of legs with their eyes in register, placing the connectors l9 and 2G in embracing relation to the pairs of overlapped fittings, and passing the axle rod through the alined holes in the connector lugs and eye fittings.
  • the axle is then secured against endwise displacement by washers 39 and 3
  • V Braces are provided to limit the distance to which the legs can spread apart and prevent collapsing of the structure when in use.
  • Such braces are formed by bars 33 and 34 pivoted to the legs I0 and 15, respectively, and a similar pair of bars pivoted to the legs at the opposite side of the structure.
  • the bars are connected together by a pivot 35 equally distant from both points of connection of the bars with the legs; and the bar 34 is formed with an extension which is arranged to bear on the upper side of a stop 35 on bar 33 when the bars are extended in line.
  • the structure can be collapsed by raising the joint between the bracing bars and bringing the pairs of legs together, as shown in Fig. 3, and can be stowed away in a small space when not in use. It can be erected for use instantaneously by grasping the legs of both pairs and moving them rapidly apart so that the brace bars are extended into their alined and blocked position. and placing the structure upright on the ground or other supporting surface.
  • Such provision is here embodied in a pointer 31 mounted-in'radial relation to the axle [8 adjacent to the outer side of the web '24 of the connector is, and angle indicator 38 and 39 on the outer face of web 24.
  • the pointer is pivoted coaxially on one end of axle [3, which projects slightly beyond the lug 2
  • Fig. 6 shows means for'so clamping the axle as a set screw 32 passing through the'eye fitting N5 of leg l5. An opening is formed in 'the bottom of the connector I?” through which the screw is accessible.
  • the angle indicators are symmetrically disposed angularly at opposite sides of the median line of connector l9 around the pivotal axis thereof. In this illustration they have the form of three trapezoidal raised areas bearing the numbers 3, 4 and 5, respectively, at each side of the median line.
  • the areas on which numeral 3 are applied subtend an angle from to from the vertical, the areas bearing the numeral 4 subtend an angle of 30 to and those bearing the numeral 5 an angle of 40 to these being the range of angles through which bodies are tilted in inducing artificial respiration.
  • the butt ends of the screwsZl and 28 are disposed in position to ,engagei the legs 15 and H1, respectively, when the connector has been tilted 50 in either direction, and the screws of the other connector are similarly disposed to engage the legs at the other side of the supporting structure.
  • the inclination in either direction is limited to 50, which is the greatest allowable inclination when the subjects head is downward, since if tilted to a steeper angle, there is danger that the blood pressure will be increased to such an extent that the victim will remain or become unconscious.
  • Each of the raised areas has distinct side edges which can be felt and. distinguished by the fingers of an operator. Thus the device can be operated accurately in the dark, if necessary.
  • a stretcher bearing a person whose breathing has ceased can be placed immediately on the connectors I9 and 20.
  • the width of the structure and length of the axle rod are established with reference to conventional stretchers so that the width between the outer webs of the two connectors is enough greater than the extended width of the stretcher to receive the stretcher between them, and the lips 23 of the two connectors are spaced apart by a distance less than that between the inner faces of the side bars of the stretcher.
  • Figs. 1 and 2 where a and b designate the side bars of a stretcher and c designates the fabric body support between them.
  • Fig. 5 shows one of the side bars and a portion of the fabric support.
  • the stretcher is placed so that the mid length of a persons body is brought over the axle rod and is lowered upon the connectors.
  • the combined weight of stretcher and body causes the spurs 28 of the connectors to penetrate the side members ofthe stretcher suihciently to hold them against endwise movement when the stretcher is tilted.
  • the stretcher is additionally forcedagainst the holdingspurs, and the superposed body confined so that it cannot shift when tilted, by straps which are engaged with the connectors and pass over the body across the small of the back and across the thighs close to the buttocks.
  • Two straps t3 and M are provided for this purpose. Each strap is doubledat a point between mid length and one end to form a loop 45 (Fig.
  • each strap is passed through one of the slots in one of the connectors (for instance, the strap 43 is passed through the slot 25, and the strap '44 through slot 26, of connector IS), in such manner that the mid length portion of the strap. is underneath and the ends are above.
  • a spring actuated gripper 41 is secured to the strap end which runs from the loop 45, and the opposite strap end is passed through the gripper in such manner that it can be pulled through to tighten the strap when the hook 253 is engaged with the opposite connector (for example, the connector 20).
  • Both straps are connected semipermanently by means of the parts which pass through the slots 25 and 26 around the adjacent edges of the web 24 of one connector and into engagement with grippers M; and they are normally detached from, but quickly engageable with, the other connector by means of the hooks 45.
  • the spacing between the slots 25 and 26 of both connectors and their opposite inclinations cause the straps to diverge and then converge in passing across the stretcher.
  • the straps naturally fall into position above and below the buttocks of a. person lying prone on the stretcher when, being in slackened condition, they are laid across the body and hooked into the connector at one side. When adequately tightened after being located in place, they securely hold the'body against shifting and without applying collapsing pressure to the abdomen.
  • An apparatus for inducing respiration comprising a supporting structure and two stretcher connectors pivotally mounted on said structure coaxially and spaced apart from one another, each of said connectors having a channel extending transversely of the pivot axis adapted to receive separably a longitudinal element of a stretcher and having a pointed spur rising from the bottom of its channel arranged to indent such longitudinal element to prevent lengthwise slip thereof relative to the connector.
  • An apparatus for inducing respiration comprising a supporting structure and two stretcher connectors pivotally mounted on said structure coaxially and spaced apart from one another, each of said connectors having a channel extending transversely of the pivot axis adapted to receive separably a longitudinal element of a stretcher, and screws mounted in the connector at opposite sides of a line passing through its pivot axis perpendicular to the bottom of the channel therein, said screws having pointed ends protruding above the channel bottom for indenting engagement with a stretcher element and arranged to engage the supporting structure when the connector is rocked about its pivot axis whereby to limit; the extent of rocking movement of the connector.
