Definitions

  • the present invention generally belongs to the field of the emergency healthcare.
  • the object of the present invention is a new anchoring system for a stretcher which prevents, in a simple and effective manner, the person operating it from having to support a considerable part of its weight during an operation of introducing it into an ambulance.
  • stretchers commonly used in emergency healthcare feature retractable legs having two usage positions: an extended position in which the legs are extended so as to allow moving a patient over the surface of the floor or ground; and a compressed position in which the legs are compressed such that the stretcher can be placed on the lower surface of an ambulance patient compartment.
  • the operation of introducing a stretcher into the ambulance involves the stretcher transitioning from the extended position to the compressed position.
  • the folding up can be done in various ways, for example due to the retractable legs (101) hitting against the lower edge of the ambulance patient compartment.
  • the stretcher (100) is supported on the rear pair of retractable legs (101) and on the auxiliary wheels (102), as shown in Figure 1a . Therefore, in this situation the paramedic is still not supporting any weight.
  • the stretcher (100) is supported only on the auxiliary wheels (102), and the paramedic must therefore hold the stretcher (100) at its rear end, supporting virtually all the weight of the stretcher and the patient. This situation is depicted in Figure 1b .
  • Document EP 2412356 A1 discloses a device for the introduction of stretchers into ambulances, which comprises a movable tray slidably mounted on fixed guides arranged on the inner floor of the ambulance, so that the movable tray can be moved from a retracted position, where the tray is completely withdrawn in the ambulance, and an extended position, where the tray is extended out the of the ambulance to receive the stretcher.
  • the stretcher is loaded on the movable tray in extended position
  • the center of gravity of the stretcher falls within the tray, so that the stretcher is fully supported on the tray.
  • the paramedic can fold the legs of the stretcher and the movable tray is moved in the retracted position to place the stretcher on the internal floor of the ambulance.
  • This latter known device is, however, particularly complex.
  • the anchoring system is designed for anchoring a stretcher to an ambulance floor, wherein the stretcher comprises a rectangular frame supporting a surface for bearing the patient and to which there are fixed two pairs of retractable legs equipped with wheels at their free ends.
  • the frame is typically formed by four bars that are parallel to one another in twos, where the two longest bars are referred to as “side bars” and the two shortest bars are referred to as " end bars ".
  • the legs there are two pairs of conventional retractable legs that can alternate between an extended position, in which they allow moving the stretcher by rolling it over the floor or ground, and a retracted position, designed for when the stretcher is inside the ambulance.
  • the retractable legs have wheels at their lower end that allow moving the stretcher over the floor or ground.
  • front end of the stretcher will be interpreted herein according to the direction of movement of said stretcher upon introducing it into the ambulance.
  • front end of the stretcher is that end which is first introduced into the ambulance.
  • rear end of the stretcher will be interpreted according to the direction of movement of said stretcher upon introducing it into the ambulance. Therefore, the “rear end” of the stretcher is that end which enters the ambulance last.
  • longitudinal direction refers to the natural direction of movement of the stretcher for introducing same into the ambulance, and therefore also to the direction of the rails arranged therein.
  • the anchoring system of the invention comprises:
  • anchoring system of the invention differs from them fundamentally in that it further comprises the following features.
  • This novel anchoring system is therefore as follows.
  • the paramedic first pushes the stretcher with its front end towards the ambulance such that the first pair of auxiliary wheels enters the rails.
  • the paramedic then continues pushing until the second pair of auxiliary wheels also enters the rails. Since the profile of the rails has an upper horizontal segment, none of the auxiliary wheels can move vertically upwards, i.e., none of the auxiliary wheels can lift off the ambulance floor. Therefore, the stretcher cannot tip over when the retractable legs fold up, since it is forced to maintain its horizontal position.
  • the paramedic can thereby retract the retractable legs, either by hand or automatically, and then finish completely introducing the stretcher into the ambulance, making the pairs of auxiliary wheels roll forward in the rails.
  • the paramedic does not need to hold the weight of the stretcher and the patient at any time throughout the entire operation.
  • the system further comprises centering rollers arranged in a position adjacent to each of the auxiliary wheels.
  • they can be rollers having a vertical axis of rotation which are fixed to the connecting element between the auxiliary wheels and the corresponding side bar of the frame of the stretcher. These rollers tend to center the auxiliary wheels with respect to the ends where said rollers enter the rails, thereby making the initial operation of introducing the auxiliary wheels into the rails easier when the stretcher is introduced into the ambulance.
  • the anchoring system further comprises locking means which are automatically activated after the second pair of auxiliary wheels enters the rails to prevent any longitudinal movement of the auxiliary wheels along the rails.
  • these locking means are automatically activated once the stretcher is completely supported by the anchoring system.
  • the locking means prevent an outward longitudinal movement of the stretcher, which causes the second auxiliary wheels to pop out of the rails, with the subsequent risk of the stretcher tipping over, from taking place. For example, this is particularly useful when the ambulance is located on a sloped surface. Therefore, once the locking means are activated, the paramedic can then fold up the retractable legs, by hand or automatically depending on the particular design of the stretcher, without the risk of said stretcher rolling out of the ambulance.
  • the anchoring system further comprises means for unlocking the locking means that can be operated from a rear end of the stretcher. This will allow the paramedic to deactivate the locking means once the retractable legs have been completely folded up, such that said paramedic can then continue pushing the stretcher into the ambulance.
  • the locking means can be configured in different ways, depending on each particular application, although in one particularly preferred embodiment of the invention, the locking means comprise a spring-driven projection rigidly fixed to the frame of the stretcher, and a corresponding housing rigidly fixed to the pair of horizontal rails.
  • the expression " rigidly fixed " to the frame of the stretcher or to the horizontal rails includes both a direct fixing to said elements and an indirect fixing through other parts.
  • the underlying concept is that the projection moves integrally with the stretcher and the housing is in a fixed position like the horizontal rails are.
  • the respective positions of the projection and the housing are conceived so that the projection gradually moves closer to the housing as the first auxiliary wheels longitudinally move along the rails into the ambulance. The projection reaches the position in which the housing is located and is automatically introduced therein once the second auxiliary wheels have entered the rails.
  • FIG. 2 shows a perspective view of a stretcher (1) equipped with an anchoring system according to the present invention.
  • the stretcher (1) is fundamentally formed by a frame (11) having a rectangular shape with two lateral sides in the longitudinal direction, and rear and front sides perpendicular to the longitudinal direction.
  • a horizontal surface (12) which is usually cushioned, is fixed to the frame (11) so as to allow the patient to lie or sit down on same.
  • rear retractable legs (13t) and front retractable legs (13d), respectively are fixed to the frame (11) on the lower part thereof.
  • Retractable legs (13t, 13d) are known in the art and can be implemented in different ways, although as can be seen in Figure 2 they adopt a scissor structure which allows alternating between an extended position and a folded up position.
  • the free ends of the retractable legs (13t, 13d) comprise wheels which allow moving the stretcher (1) over the floor or ground before introducing it into the ambulance.
  • This stretcher (1) also includes a pair of first auxiliary wheels (3) fixed to the side bars of the frame (11) in a front portion of said side bars, as can be seen in further detail in Figure 3 .
  • first auxiliary wheels (3) are fixed through a rigid connecting element to the front end of the side bars of the frame (11).
  • a pair of second auxiliary wheels (4) is located a greater distance away from the front end of the side bars of the frame (11) in a fixed manner.
  • the first and second auxiliary wheels (3, 4) are aligned in twos for the purpose of allowing them to be introduced into the rails (2) which will be described below.
  • Centering rollers (5) which are fixed to the connecting elements between the auxiliary wheels (3, 4) and the side bars of the frame (11) in this example, are also seen in Figure 3 .
  • the centering rollers (5) have a cylindrical shape and are oriented in the vertical direction. Their position, next to the auxiliary wheels (3, 4) and somewhat ahead of them, allow for their guiding function to make it easier to introduce the auxiliary wheels (3, 4) into the rails (2), as will be described in further detail below.
  • the locking projection (6a) cooperating with a housing (6b) to lock the position of the stretcher (1) with respect to the rails (2) can also be seen in Figure 3 . It must be observed that this configuration of the locking means (6a, 6b) constitutes only one example, and that other types of mechanisms and other locations would be possible. The operation of the locking means (6a, 6b) will also be described herein in further detail below.
  • Figures 4 to 6 show a structure which is designed for being fixed to the ambulance floor and includes the rails (2).
  • the rails (2) are separated from one another by a distance equal to the gap between the auxiliary wheels (3, 4), and have an essentially C-shape formed by three segments: a lower horizontal segment (21), an intermediate vertical segment (22), and an upper horizontal segment (23).
  • the distance between the upper surface of the lower horizontal segment (21) and the lower surface of the upper horizontal segment (23) is essentially equal to the diameter of the auxiliary wheels (3, 4).
  • the auxiliary wheels (3, 4) can thereby roll in the longitudinal direction supported on the inner horizontal segment (21), its highest point almost rubbing against the upper horizontal segment (23).
  • Figures 7 and 8 show a stretcher (1) with an anchoring system according to the invention at an initial moment of introducing it into an ambulance.
  • the first auxiliary wheels (3) are introduced through the end of the rails (2).
  • the centering rollers (5) help the paramedic to suitably center the first auxiliary wheels (3) with the open end of the rails, thereby making it easier to introduce it into the rails.
  • the paramedic then pushes the stretcher (1) until also introducing the second auxiliary wheels (4) into the rails (2).
  • the projection (6a) is introduced into the housing (6b) and thereby prevents any longitudinal movement of the stretcher (1).
  • FIGs 9a and 9b schematically show an actual case in which the stretcher (1) is first introduced into the ambulance according to the process described above until the means (6a, 6b) are activated.
  • the position of the stretcher (1) is locked with the two pairs of auxiliary wheels (3, 4) introduced into the rails (2).
  • the retractable legs (13t, 13d) are folded up.
  • the operation of folding up the retractable legs (13t, 13d) can be carried out by hand or automatically, for example by means of using mechanisms based on springs, hydraulic cylinders, electric motors, or the like. Once the legs (13t, 13d) are completely folded up, the paramedic must simply push the stretcher (1) until completely introducing it into the ambulance.
  • this mode of use completely eliminates the need for the paramedic to support the weight of the stretcher (1) and the patient during the operation of introducing the stretcher (1) into the ambulance, thereby resolving the problems that have been described.
