Definitions

  • the present invention relates to a frame for transporting a stretcher.
  • stretcher refers to a device for supporting a person, generally infirm, configured to allow the suitable movement of the same. Stretchers are widely used in the medical and paramedical professions in order to allow the transfer of a patient from the location in which she/he is located to a location suitable for the administration of adequate medical support.
  • stretchers are part of the basic equipment with which a common ambulance is equipped in order to allow paramedic staff to provide the necessary aid to people in need, for example at the location of a road accident or at the location where a person has fallen ill.
  • the person is placed lying down on the stretcher, in a position suitable for limiting the occurrence of complications, in order to be able to transport the person onto the ambulance, and thanks to them also to transport the patient to a facility designed to provide suitable health care, for example a hospital.
  • Stretchers are also widely used inside sanitary facilities, allowing the hospital nursing staff to transport patients who cannot walk inside the structure, allowing the patients to have the necessary therapies they must undergo performed.
  • Stretchers are generally connected to suitable transport frames configured to allow the support thereof and facilitate their movement.
  • the aforementioned structures have movement modules equipped with wheels which allow the responsible staff to move the stretcher by exerting force on the frame.
  • these frames can comprise articulated members which allow an adjustment of the positioning of the stretcher with respect to the ground.
  • the frames of more modern conception have motor-driven articulated members configured for adjusting the height of the stretcher with respect to the ground.
  • these motor-driven articulated members can cooperate with assisted loading devices that allow loading the stretcher and frame in an autonomous way on a support for transport, for example an ambulance.
  • This type of frame requires, during the course of its operating life, an accurate maintenance in order to ensure adequate and efficient operation.
  • the object of the present invention is therefore to provide a frame for transporting a stretcher capable of allowing an adequate and precise evaluation of the need for maintenance interventions which does not require specific operator skills.
  • frame 1 a supporting frame for a stretcher
  • the frame 1 comprises two movement modules 2.
  • Each of these movement modules 2 comprises two wheels 3 respectively connected to the ends of a supporting crosspiece 4.
  • the supporting crosspiece 4 is connected to supporting means 5 through a first connection portion C1.
  • these supporting means 5 comprise a first four-bar linkage mechanism 6 mounted on the movement module 2 and a second four-bar linkage mechanism 7 interposed between the first four-bar linkage mechanism 6 and a supporting platform 8 for a stretcher "B".
  • the supporting platform 8 is configured for receiving in coupling a table of a stretcher "B" by reversible connection means (not shown in the appended figures) which allow a reversible connection between the supporting platform and the aforementioned stretcher "B".
  • these reversible connection means comprise shape couplings of the male-female type and/or couplings of the screw-bolt type.
  • the stretcher "B” rests on the platform 8 coming into contact with at least one, preferably four, load cell(s) 13.
  • the aforementioned movement modules 2 are respectively connected to a front portion 8a of the supporting platform 8 and to a rear portion 8b of the supporting platform 8.
  • the first four-bar linkage mechanism 6 is connected to the second four-bar linkage mechanism 7 through a second connection portion C2. Moreover, the aforementioned second four-bar linkage mechanism 7 is connected to a crosspiece 9 by means of a third connection portion C3.
  • the crosspiece 9 is preferably equipped with receiving seats designed to allow a coupling, preferably a shape coupling, with the supporting platform 8.
  • the receiving seats are U-shaped to receive respective longitudinal members "L" of the supporting platform 8.
  • the coordinated adjustment of the supporting means 5 of the movement modules 2 connected respectively to the front portion 8a and rear portion 8b of the platform 8 allows compensating for the unevenness of the surface on which the frame 1 is moved.
  • the differentiated adjustment of the supporting means 5 allows, during an operational movement of the frame 1, varying the angle of orientation of the supporting platform 8 corresponding to an angle of inclination with respect to a transverse direction of the stretcher "B".
  • these supporting means 5 are actuated through the use of at least one electromechanical actuator 12.
  • actuators are at least partially connected to the movement module 2.
  • the four-bar linkage mechanisms 6, 7 can be absent and the supporting means 5 can comprise a robotic arm having a first portion connected to the movement module 2 and a second portion connected to the supporting platform 8.
  • the supporting means 5 are designed to allow the adjustment of the height and at least one angle of orientation of the aforementioned supporting platform 8 during an operational movement of the frame 1, allowing to compensate for irregularities and/or inclinations of the surface on which the frame 1 is moved while maintaining a predetermined spatial orientation of the supporting platform 8, for example a horizontal orientation with respect to an absolute reference system.
  • the supporting crosspiece 4 of the movement module 2 can also be realised in the form of a drive shaft on which the wheels 3 are directly placed.
  • the movement module 2 can comprise a different number of wheels 3 and the aforementioned wheels 3 can have a different arrangement from the previously mentioned arrangement without altering the inventive concept of the present invention.
  • the frame 1 comprises a control module (not shown in the appended figures) operatively connected to the supporting means 5 and configured for realising a loading of the transport frame 1 on an external support plane, for example a support plane of an ambulance.
  • a control module (not shown in the appended figures) operatively connected to the supporting means 5 and configured for realising a loading of the transport frame 1 on an external support plane, for example a support plane of an ambulance.
  • the frame 1 further comprises a legible storage support 10 and detection means 11 designed to detect a plurality of measurements indicating operating parameters of the frame 1.
  • legible storage support 10 is operatively associated with the detection means 11 and is programmed for storing a plurality of measurements to allow a subsequent diagnosis relative to the operating conditions of the frame 1.
  • the detection means 11 acquire measurements indicating the operation of the frame 1 and these measurements are stored in the legible storage support 10 to be subsequently evaluated in order to determine the need to carry out maintenance works on the frame 1.
  • the detection means 11 and/or the legible storage support 10 are/is housed at least partly inside a seat specially formed in the movement module 2 and/or in the supporting means 5.
  • the detection means 11 and/or the legible storage support 10 are supplied, preferably, by an electric battery.
  • these detection means 11 comprise at least one accelerometer connected to the frame 1.
  • the accelerometer allows detecting the states of acceleration to which the frame 1 is subjected during its operating life.
  • the accelerations recorded by the accelerometer allow detecting the occurrence of events which are harmful for the frame 1, for example an impact to which, accidentally, the frame 1 can be subjected during movement operations.
  • the combined analysis of the measurements detected by a plurality of accelerometers allows precisely determining the portion of the frame 1 which was involved, for example in the aforementioned impact, providing indication on the portion of the frame 1 that could require maintenance.
  • the detection means 11 comprise at least one gyroscope designed to detect an angular speed relative to a predetermined position of the frame 1.
  • the analysis of the speed detected by the gyroscope allows determining the movements to which the frame 1 is subjected during its use. In particular, these movements represent an index of the degree of wear of the frame 1.
  • the detection means 11 can also detect, interacting with the at least one load cell 13, the number of times that the stretcher "B" is coupled to/uncoupled from the supporting platform 8 and the weight that the supporting platform, by means of the movement module 2, transported.
  • the analysis of the measurements detected by the gyroscopes allows setting preventive maintenance works.
  • maintenance interventions are performed such as revision, replacement and/or repair, with scheduled deadlines and before the component manifests any failure.
  • the detection means 11 comprise at least one electromechanical system of the MEMS type.
  • MEMS Micro Electro-Mechanical Systems
  • such systems have a very reduced size and limit the inertia of the frame 1.
  • the detection means comprise electromechanical systems with dimensions other than those indicated above without altering the inventive concept of the present invention.
  • the frame 1 comprises a diagnosis module operatively associated with the legible storage support 10.
  • This diagnosis module generates a signal describing an operating condition of the frame 1 as a function of the plurality of measurements carried out by the detection means 11.
  • the diagnosis module is configured for generating a warning signal when the aforementioned descriptive signal exceeds a predetermined threshold value.
  • the diagnosis module helps to increase the safety of the frame 1, alerting the user in an intuitive way of the need to perform maintenance works.
  • the frame 1 comprises a transmission module configured for transmitting the measurements acquired by the detection means 11 to an external support.
  • the transmission module preferably comprises a radio-transmitter configured to transmit the measurements in radio frequency.
  • the transmission module can comprise wired connectors and the nature of the signal can be of a different type without altering the inventive concept of the present invention.
  • the detection means 11 acquire a plurality of measurements relating to the operation of the frame 1. These measurements are stored by the legible storage support 10 to allow a subsequent diagnosis designed to determine the need for maintenance on the frame 1.
  • the present invention fully achieves the intended objects thanks to a frame for transporting a stretcher able to allow an adequate and precise evaluation of the need for maintenance interventions regardless of the skill of the operator by virtue of the presence of detection means and a legible storage support associated thereto that allow detecting and storing a plurality of measurements to allow a subsequent diagnosis of the operating conditions of the frame.
  • this diagnosis allows limiting the amount of time required for maintenance interventions, as it precisely determines the maintenance works to be carried out by means of an analysis of the operating parameters of the frame.
