Definitions

  • the present invention relates to the field of patient transport trolleys that are usually found in hospitals, especially in emergency departments.
  • This type of trolley is also called a stretcher trolley.
  • the upper ends of the arms are generally pivotally mounted relative to the upper frame.
  • the lifting arms are sometimes articulated in several points, which makes their realization quite complex.
  • An object of the invention is to provide a transport trolley for a patient having an alternative to known height-adjustable trolleys.
  • first and second lift arms are articulated only with respect to the lower and upper frame, and not in more ways like some existing solutions elsewhere. This facilitates the manufacture of the lift arms, but also to strengthen them, which improves the robustness of the truck.
  • Both actuators allow the first and second lift arms to be pivoted independently of each other, which makes it easy to adjust the angle of inclination of the coating.
  • the actuators are cylinders, pneumatic type.
  • the upper frame comprises two longitudinal support members extending on either side of the coating, and the upper end of the first arm is pivotally mounted to each of the support elements.
  • connection between the upper end of the first lifting arm and the upper frame is at two points.
  • the upper end comprises a cross member extending perpendicularly to the first lifting arm and whose two ends are mounted in pivot connection relative to the upper frame.
  • the upper end of the second arm cooperates only with one of the two longitudinal support members.
  • connection between the upper end of the second lifting arm and the upper frame is at a single point.
  • the second arm is mounted cantilever and takes back in one point the weight of the upper frame head.
  • An advantage of this first embodiment is that, in the absence of a second connection point between the second lifting arm and the head side of the upper frame, the area below the head side of the upper frame is largely free, which makes it easy to place a medical device under the upper frame, or even allows the doctor to be easily and comfortably installed near the upper part of the patient's body.
  • the upper end of the second arm is provided with an articulated shoe which is engaged in a guide rail fixed under the head side of the upper frame.
  • a technical rail is used.
  • the guide rail is fixed under one of the aforementioned longitudinal support elements.
  • the upper end of the second arm is provided with a transverse bar which comprises a roller at each of its two ends, each of the longitudinal support elements comprises a slide disposed on the head side of the upper frame, and the rollers cooperate with the slideways to allow the sliding of the upper end of the second arm relative to the head side of the upper frame.
  • connection between the upper end of the second lifting arm and the upper frame is at two points.
  • An advantage of the second embodiment of the carriage with respect to the first is that it is less expensive in that it does not require a rail capable of supporting cantilever mounting.
  • the lower frame has the shape of a "U" consisting of two transverse portions connected by a longitudinal portion, the pivot links of the first and second lifting arms being located in the longitudinal portion, while the ends of the transverse portions carry the wheels of the carriage.
  • the lifting arms are offset on a lateral edge of the carriage to clear a space under the upper frame, whereby the stretcher trolley according to the invention can be brought under a radiology equipment, such as an amplifier. shine, or any other medical device requiring access to an area under the patient lying down. These devices most often have an arc portion whose ends are placed above and below the coating.
  • a radiology equipment such as an amplifier. shine, or any other medical device requiring access to an area under the patient lying down.
  • These devices most often have an arc portion whose ends are placed above and below the coating.
  • the "U" shape of the lower frame also facilitates the positioning of the carriage under such an apparatus, insofar as the lower portion of the arc portion of the image intensifier can be housed between the two transverse portions of the lower frame. It is understood in particular that the lift arms, offset on one side of the carriage, do not interfere with the positioning of the carriage under the radiology apparatus.
  • the upper end of the second arm cooperates only with the longitudinal support member which is arranged on the side of the longitudinal portion, which allows to release even more space under the upper frame.
  • the bodies of the actuators are fixed in the central part of the longitudinal portion, while their rods extend towards the transverse portions.
  • the actuators in this case the two cylinders, so are mounted back to back.
  • This arrangement has the advantage of being compact, the actuators also being offset on a side edge of the carriage.
  • the actuators are fixed below the longitudinal portion.
  • first and second lift arms have curved portions in the form of a "C" facing the longitudinal ends of the carriage.
  • FIG. 1 there is shown in perspective a first embodiment of a transport carriage 10 for a patient.
  • This type of trolley also called stretcher trolley, is mainly intended for use in hospitals, especially in emergency departments.

  • the upper frame 22 has a head 22a and a foot 22b side .
  • the part of the coating which is located on the head side 22a can pivot relative to the rest of the coating as can be understood by referring to the figure 4 .
  • the upper frame 22, and more precisely the frame 28, is connected to the lower frame 12 via a first lifting arm 30 and a second lifting arm 32 which allow the displacement of the upper frame 22 relative to the lower frame 12.
  • the first lifting arm 30 is pivotally mounted to the longitudinal portion 18 about a pivot axis A which is perpendicular to the longitudinal direction L of the coating.
  • the second lifting arm 32 is pivotally mounted to the longitudinal portion 18 about a pivot axis B, the latter also being perpendicular to the longitudinal direction L of the coating.
  • the axes of rotation A and B are distinct.
  • the first and second lifting arms 30, 32 are symmetrical with respect to each other with respect to a vertical plane perpendicular to the longitudinal direction L of the coating.
  • the first lift arm 30 has a first beam 34 attached to a first arcuate portion 36, while the second lift arm 32 includes a second beam 38 integrally attached to a second arcuate portion 40.
  • the first and second arcuate portions 36, 40 have the shape of a "C" facing the outside of the carriage.
  • first and second arcuate portions 36, 40 which are pivotally attached to the longitudinal portion 18.
  • the upper end 30a of the first lifting arm 30 constituted by the upper end 34a of the first beam is pivotally mounted to the foot side 22b of the upper frame 22.
  • This first actuator 52 is a pneumatic cylinder having a body 54 pivotally attached to a plate 56 which is itself secured to the longitudinal portion 18.
