Definitions

  • the present invention relates to a mobile rescue stretcher, in particular for transport in ambulance vehicles, comprising a chassis having wheels and a patient stretcher supported by this, in order to change the height of the patient stretcher above the wheels, the chassis geometry is adjusted by means of a pressure supply unit and at least one linear actuator that can be acted upon by this hydraulic drive system can be changed, which also has a manually operable unlocking valve unit for direct connection of a lifting working space of the linear actuator with a receiving space for hydraulic fluid.
  • Mobile rescue couches such as those used in particular to transport sick or injured people to or from an ambulance vehicle, are generally known.
  • Various mechanisms are known for adjusting the height of the patient bed, for example in order to adjust it to the level of a treatment table after the patient has arrived in a clinic, and thus to facilitate the transfer of the patient with minimal risk, including, as explained above, hydraulic drive systems.
  • These are used in the same way to retract the chassis of the rescue couch—already suspended with one end in a corresponding receptacle of the ambulance vehicle—when the latter (loaded or unloaded) is to be accommodated in the ambulance vehicle.
  • the state of the art is for example, to refer to the following documents: WO 2016/076908 A1 , WO 2011/088169 A1 , WO 2014/134321 A1 , WO 2005/122989 A1 , WO 2006/004820 A1 , WO 2015/073792 A2 , WO 2014/089180 A1 , WO 2011/041170 A2 , WO 2009/085332 A1 and WO 2006/036980 A1 .
  • the present invention has set itself the task of providing a mobile rescue bed of the generic type which is improved over the prior art in terms of its suitability for use in practice.
  • the space required for the manually operable unlocking valve unit and its operating mechanism should be particularly small, with a high level of safety with regard to possible incorrect operations or malfunctions .
  • the unlocking valve unit has a control chamber which is delimited by a piston element which is movably guided relative to the housing of the valve unit and which communicates with the connection connected to the lifting working chamber, the piston element having is operatively connected to a valve body which interacts with a valve seat of a relief valve formed between the connection connected to the lifting working space and the connection connected to the receiving space, and wherein a mechanical actuation input of the valve unit acts on the valve body with the interposition of a spring element.
  • the rescue bed according to the invention is characterized by a complex unlocking valve unit with integrated safety functionality such that the pressure prevailing in the working space of the linear actuator of the hydraulic drive system is an indicator of the loading of the patient bed is connected to a control chamber and acts on a piston element arranged therein and connected to a valve body of the relief valve.
  • a mechanical actuation input of the valve unit acts on the valve body with the interposition of a spring element in such a way that - as a result of a suitable adjustment of the spring element to the counterforce exerted on the piston element by the pressure in the control chamber - manual actuation of the mechanical actuation input is only possible up to a predetermined pressure level in the control chamber leads to a displacement of the valve body, opening the relief valve, whereas if the pressure in the control chamber is above the specified pressure level, manual actuation of the mechanical actuation input leads to compression of the spring element - with the position of the valve body remaining unchanged and the relief valve thus remaining closed.
  • a safety function is integrated in the smallest of spaces in the unlocking valve unit, which prevents hydraulic fluid from flowing directly from the lifting working chamber of the linear actuator into the receiving chamber for hydraulic fluid when the patient bed is loaded - via an open relief valve - and the patient bed sagging rapidly.
  • the piston element and the valve body are part of a rigid valve body assembly.
  • the piston element can be firmly attached to the valve body (by screwing, pressing on or some other joining technique). With such a connection, the movements of the piston element and Valve body coupled directly.
  • the risk of the switching characteristics of the unlocking valve unit changing as a result of external influences, in particular of its safety function (see above), is low on this.
  • an annular control chamber is provided, which is delimited by a piston element having an annular active surface.
  • This configuration favors the desired particularly compact, space-saving design of the unlocking valve unit.
  • the control chamber is particularly preferably delimited radially on the outside by the housing of the valve unit and radially on the inside by the valve body assembly.
  • a closing spring acting on the valve body in the sense of closing the relief valve can also be arranged in the annular control chamber. This also contributes to a particularly compact design of the entire unlocking valve unit, including the implemented safety functionality.
  • the spring element functionally downstream of the mechanical actuation input—acts on the piston element.
  • Spring element can be designed in particular as a helical spring. This can particularly preferably be dimensioned in such a way that its diameter essentially corresponds to the diameter of the—opposite—effective surface of the piston element. This favors the realization of a spring characteristic that is advantageous for the safety functionality that is essential here; and an offset between the spring force on the one hand and the hydraulic counterforce on the other hand, as is implied by the control pressure prevailing in the control chamber and acting on the effective piston area, is avoided. This is contrary to the reliability of the function.
  • the mechanical actuation input is assigned a mechanical stop which prevents further movement of the actuation input in a position in which the capacity of the spring element is not yet exhausted.
  • the stop in question is preferably implemented in or on the housing of the valve unit.
  • the valve body of the unlocking valve unit is particularly preferably assigned an actuating element which is coupled to the valve body and which can assume a position in which it opens a check valve which is located between a connection connected to the lowering working chamber of the linear actuator and the connection connected to the Recording space associated connection is arranged.
  • an actuating element can form a projection of the valve body, in particular directly be molded to this.
  • the actuating element is dimensioned such that the opening of the check valve - this is designed in a particularly preferred embodiment of the invention as a check valve with the blocking direction from the lowering working chamber to the receiving chamber - occurs slightly offset compared to the opening of the relief valve.
  • the valve body In the event of a movement of the valve body--particularly induced by activation of the mechanical actuation input--the valve body lifts off the valve seat of the relief valve in this case before the shut-off valve is also opened--somewhat delayed. If both the relief valve and the check valve are open when the valve body is in a corresponding position, the result is that the two working spaces of the linear actuator, i.e. the lifting working space and the lowering working space, are fluidically connected directly to one another through the unlocking valve unit and to the connection to the Connected receiving space for hydraulic fluid. In this way, the chassis can be both extended and retracted rapidly, bypassing the hydraulic unit, with any difference in volume change that may exist between the two working chambers being compensated for by a compensating flow from or to the receiving chamber for hydraulic fluid.
  • a flow throttle In order to influence the speed at which, when the relief valve is open, the patient bed is lowered when the chassis of the rescue couch is on the floor or the chassis is lowered when the patient couch is raised, according to yet another preferred embodiment of the invention, there is between the working space with the lifting connected port and the one with the Receiving space for the hydraulic fluid connected port (flow in series with the relief valve) arranged a flow throttle.
  • This flow throttle can in particular be ring-shaped or in the form of a plurality of ring sections, particularly preferably through an annular gap existing between the valve body and the valve housing or annular gap sections existing there.
  • the required size of the unlocking valve unit benefits from such a design in the sense that it is particularly compact.
  • the linear actuator has pressure relief, which is effective in the lifting working space of the linear actuator at its maximum volume.
  • pressure relief e.g. via relief notches
  • the linear actuator retracts slightly again, ie the permanently loadable end position deviates slightly from the maximum position defined by a stop.
  • the transport of sick or injured people (patients) in ambulances serving mobile rescue bed 1 comprises in a manner known as such a four-wheeled 2 having chassis 3 and supported by this patient bed 4. It is - for a change in the height H of the patient bed 4 above the wheels 2 - the geometry of the chassis 3 comprising a base frame B and a scissor lift structure S can be changed, specifically by means of a hydraulic drive system 5, which has a receiving space 6 for hydraulic fluid, a pressure supply unit 7 and at least one by this loadable - between the base frame B and the scissor lift structure S effective - linear actuator 8 includes.
  • the linear actuator 8 is designed as a double-acting differential cylinder 9 .
  • the rescue bed 1 corresponds to the sufficiently known prior art, so that further explanations are unnecessary.
  • This is suitable for a direct fluidic connection of the lifting working space 11 and the lowering working space 13 of the Produce linear actuator 8 with each other and with the receiving space 6 for hydraulic fluid, ie to ensure pressure equalization between lifting-working space 11, lowering-working space 13 and receiving space 6 for hydraulic fluid.
  • the unlocking valve unit 14 comprises a relief valve 16 designed as a seat valve 15, which is arranged in a flow path 17 extending from the lifting working chamber 11 to the receiving chamber 6, and a check valve 19 designed as a pilot operated check valve 18. which is arranged in a flow path 20 extending from the lowering working space 13 to the receiving space 6 .
  • the structural design of the unlocking valve unit 14 is in 3 illustrated. It comprises a housing 21 with a receiving bore 22 serving to accommodate the valve internals. Three connections open into this, namely a lifting connection 23 which communicates with the lifting working space 11, a lowering connection 24 which communicates with the lowering working space 13 and a lowering connection 24 and a with the receiving space 6 communicating - tank connection 25.
  • a valve seat 26 of the relief valve 16 is embodied in the receiving bore 22 between the openings of the lift connection 23 and the tank connection 25 .
  • a valve body 27 that can be displaced along the axis A in the receiving bore 22 interacts with this.
  • the lift connection 23 opens into an annular control chamber 28, delimited radially on the outside by the housing 21 and radially on the inside by the valve body 27 27 removed piston element 30 is limited with an annular piston 31 guided in the receiving bore 22 in a sealing manner.
  • a closing spring 32 is arranged in the control chamber 28, which is supported on the collar 29 and - in the area of its annular hydraulic effective surface 33 - on the piston element 30 (and thus indirectly on the valve body 27, with which the piston element 30 forms a rigid valve body -Assembly 34 is firmly connected) acts in the sense of closing the relief valve 16.
  • the unlocking valve unit 14 also has a mechanical actuating input 35 in the form of a Receiving bore 22 along the Ache A slidably recorded plunger 36 on.
  • the plunger 36 is approximately cup-shaped with an actuating boss 38 protruding from the bottom 37.
  • a lever 39 acts on this, which in turn can be coupled—for example via a Bowden cable with an unlocking handle.
  • a spring element 40 is interposed between the tappet 36 and the valve body assembly 34 so that the tappet 36 can only act on the valve body assembly 34 via the spring element 40 .
  • the spring element 40 is designed as a helical spring 41 which extends between the bottom 37 of the tappet 36 and the piston element 30 of the valve body assembly 34 .
  • a step 42 formed in the receiving bore 22 represents a mechanical stop 43 for the plunger 36, which limits the path of movement of the plunger 36, specifically in a position in which the compressibility (capacity) of the helical spring 41 is not yet exhausted.
  • a valve insert 45 is accommodated in the receiving bore 22, adjacent to the sealing plug 44 inserted at the end face.
  • the check valve 18 is implemented in this, which represents the check valve 19 already mentioned above, which is arranged between the tank connection 25 and the lowering connection 24 .
  • the check valve 18 blocks the direction of flow from the lowering connection 24 to the tank connection 25. It can be unlocked mechanically.
  • the valve body 27 comprises an actuating element 46 in the form of an unlocking pin 49 that acts on the valve ball 47, when the valve body 27 is in the appropriate position, and lifts it off the seat 48.
  • control chamber 28 has such a pressure - above a predetermined pressure level - that the hydraulic force exerted on the piston element 30 is greater than the force that can be transmitted by the helical spring 41, pressing in the plunger 36 causes the helical spring 41 to be compressed Valve body assembly 34 does not move, and the relief valve 16 remains closed, as does the check valve 19.
