Definitions

  • the invention relates to a stretcher holder according to the introductory part of claim 1.
  • stretcher storage racks are arranged with a stretcher platform or cradle which serves to hold the stretcher and thus also the patient carried on the stretcher.
  • Such ambulances or ambulance vehicles usually have a rear door through which the stretcher platform or receptacle of the stretcher support frame is accessible so that the stretcher with the patient to be transported can be placed on or removed from the stretcher support frame with displacement in the longitudinal direction of the vehicle.
  • the stretcher is locked in its intended position for the patient transport, completely located on the stretcher platform or receptacle, whereby according to EP-A-00 36 934 - it reads the preamble of claim 1 on the basis - the locking by means of the loading side End of the stretcher platform or holder can be triggered from an easily accessible lever.
  • the stretcher platform or cradle together with the stretcher that can be locked thereon and in the empty state on the stretcher support frame, can move between a transport position inserted into the vehicle a loading position protruding from the rear door can be slidably arranged to facilitate loading and unloading.
  • extension parts on the stretcher platform or receptacle which can be pulled out or folded out through the opening of the rear door in order to facilitate loading and unloading of the stretcher.
  • stretcher carriers which are also referred to as stretcher beds, are advantageous in themselves because the patient transports them particularly gently outside the vehicle and especially in the hospital area, i.e. can be driven, the stretcher can also be used as a means of transport to various examination stations, so that an undesirably frequent transfer of the patient is unnecessary.
  • the retractable undercarriage of the stretcher is basically designed in such a way that it folds out automatically into the driving position when the stretcher is pulled down from the stretcher platform or holder.
  • the driving position is below Under certain circumstances not fully achieved, for example because the ground clearance of the stretcher platform or cradle is too small and the unfolding undercarriage gets in touch with the ground prematurely.
  • the stretcher can be removed from the stretcher platform or Free admission, as the stretcher lock intended for patient transport is not yet or is no longer effective.
  • the undercarriage cannot regularly support the stretcher, i.e. the transported patient can fall from the relatively high height with the stretcher.
  • trolleys Although there are trolleys whose chassis are load-bearing even when they are not fully unfolded, trolleys of this type are not generally used. In addition, such chassis make it difficult to push the stretcher onto the stretcher platform or cradle.
  • the stretcher it is sufficient to move the stretcher to the stretcher holder during loading, that one end of the stretcher, usually its head end, projects beyond the loading-side end of the stretcher platform or receptacle by a certain amount and the gripper unit can grasp a carrying part, for example a frame cross member or an axis of the stretcher. Now the stretcher can be pulled onto the stretcher holder with the help of an assistant, the stretcher's chassis folding away after unlocking.
  • a carrying part for example a frame cross member or an axis of the stretcher.
  • the gripper unit is also provided as a restraining unit which, when the stretcher is removed from the stretcher holder, releasably holds a part near the front end in the loading direction (head end) of the stretcher at the loading end of the stretcher holder. secures against falling. This ensures a particularly high level of safety even when unloading.
  • the gripper unit which also serves as a restraining unit, runs back to an arresting position at the loading-side end of the stretcher receptacle during unloading or assumes the arresting position. In this way, a single unit can serve both as a loading aid and as a backup during unloading.
  • the retention or gripper unit is designed or arranged in such a way that it secures or allows the front end of the stretcher in the loading direction to be secured against a separation from the stretcher holder before the retractable undercarriage of the stretcher supports its position supporting the stretcher leaves. In this way, a particularly high level of safety is ensured even when loading. Because even if the paramedics slip or stumble when pushing the stretcher onto the stretcher, the stretcher cannot slide down from the stretcher.
  • the stretcher can be released from the restraint or gripper unit with a particularly high degree of safety if the front end of the stretcher in the loading direction is released by that this stretcher is raised relative to the stretcher pickup or - when the chassis of the stretcher is fully unfolded - rises.
  • an actuating device for driving the gripper or restraining unit interacts when loading with those carrying parts which can only be brought into a position activating the actuating device after the retractable chassis of a stretcher or a carrying bed has been unlocked, or when the actuating device interacts with unloading parts which can only assume a position activating the actuating device after the chassis has been folded out into a ready-to-drive position.
  • the gripper or restraint assembly and the stretcher to one another in such a way that the gripper or restraint assembly interacts with a part on the load-bearing side which is coupled to the locking of the stretcher undercarriage in such a way that the undercarriage is automatically unlocked when the stretcher on the The stretcher holder is pulled or automatically locked when the stretcher is released by the gripper or restraint unit.
  • the actuating device of the drive of the gripper or restraint unit can interact with position sensors, for example contact plates, arranged on the stretcher holder, which actuate the actuating device at predetermined positions of the stretcher on the stretcher platform or holder.
  • spindle units are arranged to drive the gripper or restraining unit, which ensure self-locking without any further structural modifications.
  • These spindle units can be driven by electric motors.
  • Such a construction offers the further advantage that the spindle units and their electric motors can optionally be exchanged for fluid, in particular hydraulic piston-cylinder units, even without major structural modification of the stretcher holder, the desired inhibition being ensured by corresponding valve units, which in the event of failure the pressure source of the piston-cylinder unit block its piston by closing off the piston working spaces.
  • the stretcher receptacle designated overall by 1, has plate-shaped or trough-shaped bearing surfaces 2 arranged in the longitudinal direction for receiving a stretcher 20, which is only shown in FIG. 4 and which can be positively retained on the bearing surfaces 2 by means of locking elements (not shown).
  • the entire stretcher holder 1 or the like is inside an ambulance 21. on a stretcher rack or the like, not shown. arranged, usually in such a way that a height adjustment of the stretcher receptacle 1 and an optionally resilient or unsprung support is made possible.
  • the stretcher holder 1 can generally be moved in the vehicle longitudinal direction between a transport position inside the vehicle and a loading position shown in FIG. 4, in which the stretcher holder 1 protrudes outwards through a rear door of the vehicle.
  • the stretcher holder 1 can be additionally inclined in the loading position in order to lower the end of the stretcher holder 1 protruding from the vehicle in order to make it easier to slide on or remove the stretcher.
  • the tiltability of the stretcher receptacle 1 about a transverse axis can also be used in the transport position to enable the patient to be stored head-down or head-up.
  • the stretcher holder 1 is usually suitable for various types of stretcher, in particular also for so-called stretcher carriers 20, which have a retractable undercarriage or wheels 22 with retractable legs 22 (see FIG. 4), the undercarriage or legs pushing in upon unlocking of the stretcher fold down onto the bearing surfaces 2 of the stretcher holder 1, so that the stretcher 20 takes up only about the height of a normal stretcher.
  • the stretcher holder 1 In order to make it easier for the paramedics to push the stretcher and in particular a stretcher 20 onto the stretcher holder 1 and to secure the stretcher 20 when it is removed from the stretcher holder 1, the stretcher holder 1 according to the invention has a motor-driven restraint or gripper unit 3, which in the longitudinal direction of the stretcher holder 1 is arranged displaceably and by means of a hook 4 or the like arranged on it. to grasp a supporting part and to pull the stretcher onto the stretcher holder 1 or its bearing surfaces 2 or to hold onto the stretcher holder.
  • the hook 4 is arranged on a carriage 5 or a carriage which is guided in the longitudinal direction of the stretcher receptacle 1 with rollers on or in rails below the bearing surfaces 2.
  • the hook 4 on the carriage 5 can be pivoted about a transverse axis 6 against the force of a suspension which seeks to urge the hook 4 into the erected end position shown in FIG. 2 and allows the hook to be folded over in the direction in which the stretcher is carried Loading the stretcher holder 1 is pulled onto the storage surfaces 2.
  • a guide roller 7 is arranged on the side of the hook 4 and cooperates with the adjacent edge of the one bearing surface 2 or a separate guide bar.
  • recesses with ramps 8 are arranged, which can be designed as flap-shaped spring-loaded parts and can be pivoted from their inclined position against spring force into an end position in which the ramps 8 are each in the same plane how the bearing surfaces 2 and the guide bar carrying the ramps 8 are located.
  • the hook 4 can grasp part of the respective stretcher near the ramps 8 and pull it onto the stretcher holder 1.
  • a plurality of contact plates 23 'and 23' are arranged on the stretcher receptacle 1 and are actuated by support rollers 24 on the stretcher side.
  • the stretcher 20 If the stretcher 20 is to be taken down from the stretcher holder 1 and for this purpose to be moved backwards in the longitudinal direction of the vehicle, the locking elements which immovably lock the stretcher 20 while traveling on the stretcher holder 1 are unlocked. Thus, the hook 4 or its drive is set in motion, and the hook 4 is shifted into a securing position near the ramps 8.
  • the support rollers 24 If the stretcher 20 is moved to the right in the drawing, the support rollers 24 first press the contact plates 23 'down. With further displacement of the stretcher 20 to the right, the legs 22 fold into the driving position, so that the stretcher 20 receives 1 contact with the ground due to the inclination of the stretcher platform or receptacle upon further displacement to the right and the support rollers 24 relieve the contact plates 23 '. This takes place after the previous load relief of the contact plates 23 'causes the carriage or carriage 5 with the hook 4 on the ramps 8 out to the right, the hook 4 folds down and the stretcher 20 releases.
  • the hook 4 When loading or when pushing the stretcher 20 onto the stretcher holder 1, the hook 4 is initially to the right of the ramps 8 in a folded position. As soon as the support rollers 24 press down the contact plates 23 ', the hook 4 automatically moves into the secured position. Now the legs 22 of the stretcher 20 are unlocked without the stretcher 20 falling down from the stretcher holder 1.
  • the stretcher 20 can be pushed further to the left, the support rollers 24 pressing down the contact plates 23 'to the left of the contact plates 23'.
  • the drive of the hook 4 is switched on and the hook 4 moves into its left end position, the stretcher 20 being pulled onto the carrier platform or holder 1 with the legs 22 unlocked.
  • a self-locking drive is provided to ensure that the carriage 5 in the event of a sudden standstill of the drive due to a malfunction, for example an interruption in the energy supply, can not suddenly release the stretcher recorded.
  • the upper part of the same in the upright position of the hook 4 can be folded away about an axis 9 parallel to the longitudinal axis of the stretcher receptacle 1. So that the otherwise covered by the hook 4 carrying parts run over the hook 4 in any case.
  • the free end of the hook 4 can be folded around the axis 9 against spring force, which tries to push the hook end back into the normal position. It may be provided that the end of the hook 4 can be locked in the laterally folded position.
  • a linear drive 10 is used to drive the carriage 5.
  • the linear drive 10 can be designed, for example, as an electrical spindle unit which moves the carriage 5 directly.
  • the electric spindle unit provided as a linear drive 10 displaces a roller 11 relative to the carrier receptacle 1.
  • a first rope or a first chain 12 runs over this roller 11, which is attached on the one hand to the carriage 5 and on the other hand to a fixed point 13 of the stretcher holder 1.
  • Another chain 14 or another rope or the like. runs from the carriage 5 in the opposite direction to the first chain 12 via a roller 15 which is immovably mounted at one end of the stretcher holder 1.
  • the chain 14 runs to a roller 16, which is arranged immovably at the other end of the stretcher holder 1. From there, the chain 14 runs over the displaceable roller 11 or a further roller that can be displaced together with the roller 11 to a further fixed point 17.
  • the carriage 5 is accordingly also compared to the roller 11 double displacement speed in one direction or the other relative to the carrier holder 1 shifted.
  • a hydraulic piston-cylinder unit can be arranged instead of the electrical spindle unit without significantly changing the construction of the stretcher holder.
  • the desired inhibition of the drive in the event of a failure of the hydraulic pressure source can be ensured by valves which in such a case close off the piston working spaces of the piston-cylinder unit and thus immobilize the piston and accordingly the carriage 5.
  • pneumatic units are also suitable if the like in the ambulance. a pneumatic pressure source is available.
  • the pinion can be arranged instead of one of the rollers 15 or 16.
  • a forced inhibition or locking can also be provided, which takes effect automatically when the drive is at a standstill or when the power supply to the drive is switched off.
  • the ramps 8 can also be arranged in a fixed manner in the positions shown in FIG. 2.
  • contact plates 23 'and 23 instead of the contact plates 23 'and 23 ⁇ other position sensors, e.g. Proximity switches or light barriers or the like can be arranged.
