Definitions

  • the object of the invention is to provide a platform that satisfies this requirement profile. You should be fastened quickly and securely to the longitudinal bars or the handles of a stretcher. In addition, it must be able to be flexibly adapted to different dimensions, in particular to different stretchers. This includes different widths of stretchers as well as stretchers whose longitudinal bars have a round or square cross-section.
  • a platform for medical devices or equipment with a base body, with at least one mechanical interface for fastening medical device or equipment being present on the base body, with a hook element being arranged on two opposite end faces of the base body, and at least one of the hook elements being connected to the base body via a pull-out guide, so that it can assume different positions relative to the base body.
  • the platform according to the invention ultimately comprises a generally rectangular base area with two end faces. On a hook element according to the invention is provided on each of the two end faces. This hook element is used to hang the platform on the longitudinal bars of a patient stretcher and to connect it to these longitudinal bars in a form-fitting manner, so that the platform can be connected to the stretcher securely and captively.
  • the platform can be attached at the head end or at the foot end or in a position between the head and foot end of the stretcher.
  • At least one of the hook elements is connected to the main body of the platform via a pull-out guide, so that the platform can be adapted to different widths of patient stretchers.
  • the pull-out guide allows the hook elements to be slid or inserted over the longitudinal bars of the stretcher in an “open” position.
  • the pull-out guide is then retracted a little until the hook elements on both sides of the base body grip the longitudinal bars or the handles of the stretcher. This creates a positive connection between the hook elements and the longitudinal beams.
  • the platform is securely and captively connected to the patient stretcher.
  • At least one of the hook elements can be displaced relative to the base body against the spring force of a spring element.
  • the spring element acts on this hook element in such a way that it assumes a basic position (relative to the base body). If the platform according to the invention is not fixed to a patient stretcher, then the hook element is located in the immediate vicinity of the end face of the base body. Then it takes the mentioned basic position. In other words: In the basic position, the distance between the hook elements is minimal.
  • the hook element or elements is/are removed from the end face of the base body with the aid of the pull-out guide(s) and against the force of the spring element.
  • This increases the distance between the two hook elements arranged on opposite end faces of the base body. i.e. they assume the above-mentioned "open" position.
  • the hook elements can be slid over the longitudinal bars or over the handles of a patient stretcher.
  • the optional spring element or a person then ensures that the distance between the hook elements is reduced again. This creates a form fit between the hook elements or the platform and the longitudinal bars of the patient stretcher.
  • An advantageous embodiment of the pull-out guide according to the invention provides that it includes a guide sword and guide means, which are formed on the base body.
  • the guide blade can be made of plastic, sheet steel or sheet aluminum.
  • the guiding means can be, for example, guiding rails which are attached to the underside or top of the platform and interact with the guiding sword.
  • the guide means are designed as a prismatic recess in the base body.
  • the base body can be produced as a one-part or multi-part plastic injection-molded part in which the recesses and the guide rails are integrated.
  • an optional end stop is provided, which effectively prevents the guide blade from being unintentionally pulled out of the recess.
  • the guide blade is designed as a sheet metal strip, for example with a cross section of 200 mm ⁇ 4 mm, then the cross section of the recess has a width of, for example, 201 mm and a thickness of 4.5 mm. On the one hand, this ensures that the guide blade can be moved easily in the recess. On the other hand, a sufficiently precise guidance of the guide sword in the recess is guaranteed.
  • the optional spring elements are preferably in the form of leaf springs or spiral springs and are particularly preferably arranged inside the base body. Then they do not represent an interference contour and do not get dirty. This facilitates cleaning and, if necessary, sterilization of the platform according to the invention.
  • the invention provides that the platform or includes locking means, by means of which one or both hook elements can be locked in their position or in their positions relative to the Body can be locked.
  • Such a locking can be realized in that a first toothing is provided on at least one of the guide swords.
  • a pawl (preferably spring-loaded) is arranged on the base body. The lock is active when the pawl enters a gap between two teeth of the first toothing. If the pawl is moved against the spring force, it moves out of the tooth gap so that the locking is released.
  • a first toothing is provided on both guide swords.
  • a pawl (preferably spring-loaded) is arranged on the base body. If both pawls are each in a gap between two teeth of the first toothing, both guide swords are locked. When both pawls are moved out of the tooth gaps, the locks are released.
  • the locking means can also be designed as a clamping screw, with the clamping screw penetrating the base body and one or both guide swords and an internal thread is screwed into the base body or a nut.
  • the clamping screw When the clamping screw is tightened, the guide blade is clamped and locked in the recess that is part of the pull-out guide.
  • the clamping screw penetrates the guide sword in the area of a slot.
  • the guide blade can be displaced relative to the clamping screw and, of course, also relative to the base body.
  • the guide bar is clamped in the recess of the base body and thus locked.
  • the clamping screw also has the function of securing the guide blade in the base body. If the elongated hole in the guide bar is closed at both ends, then the shank of the clamping screw prevents the guide bar from being unintentionally pulled out of the base body.
  • the basic form of the hook elements according to the invention is a prismatic body which has a longitudinal extension of about can have 20cm.
  • the length of the hook elements roughly corresponds to the width of the platform.
  • the hook elements according to the invention have an arcuate or L-shaped cross-section, the arc need not be an arc of a circle. It can also be designed as a polygon and consist of several more or less straight sections arranged at an angle to one another.
  • the arc encloses an angle of less than 180°. This creates a lead-in area/lead-in bevel.
  • the hook elements can be positively connected to longitudinal bars or handles of different diameters or cross-sectional profiles.
  • an inlet bevel is formed at the open end of the arc, as is illustrated in the figures in a wide variety of embodiments.
  • At least one of the two hook elements is detachably connected to the guide sword or the main body of the platform and can be connected to the guide sword or the main body of the platform in two or more positions.
  • the hook elements on the envelope can be in two different positions with the Guide sword to be connected. This is illustrated below with reference to the figures.
  • a further flexibilization and expansion of the possible uses of the platform according to the invention is achieved if one of the hook elements is rotatably attached to the guide sword or the base body. It is then also possible for the hook elements to be fastened in a form-fitting manner to bars of a patient stretcher that do not run parallel to one another (skew) or to another object from the field of emergency medicine.
  • the hook elements preferably have one or more recesses. These recesses can be used to positively connect the hook element, for example, to an end piece of a handle in the axial direction of the longitudinal bar. Such end pieces are often designed as a diameter extension, for example in the form of a mushroom-like head.
  • this head does not interfere with the secure form fit between the platform according to the invention and the longitudinal bars of a patient stretcher.
  • a further improvement in handling and resilience is achieved when the movements of the guide swords are mechanically synchronized.
  • second toothings are formed on the guide swords, and that these second toothings mesh with one and the same rotatably mounted pinion. This ensures that the guide swords or the hook elements arranged on them are located symmetrically to a center of the base body.
  • a further embodiment of a mechanical synchronization of the movements of the guide swords can be realized by a "scissors lattice.
  • figure 1 shows an isometric view of a first exemplary embodiment of a platform 1 according to the invention with a base body 3 and with a rectangular base area, on the end faces of which a hook element 5 is arranged in each case.
  • the hook elements 5 are not firmly fastened to the end face of the base body 3, but indirectly with the aid of a pull-out guide.
  • the hook elements are located in the immediate vicinity of the end faces of the base body. To a certain extent, this position is the basic position of the platform. The platform assumes the home position when not attached to a gurney.
  • the base body 3 of the platform has at least one mechanical interface for attaching medical equipment or devices.
  • This mechanical interface is usually on the top of the base body 3. It is not shown in the figures.

  • the breakthrough 11 of a guide sword 7 can be penetrated by a clamping screw.
  • the clamping screw is in the in figure 2 not shown; only the longitudinal axes of the clamping screws are in the figure 2 indicated by dash-dotted line 13.
  • the head of the clamping screw rests on the upper side of the base body 3 and the shank of the clamping screw penetrates the opening 11, then provided that the opening 11 does not go through to the end of the guide bar 7, it is ensured that the guide bar 7 cannot be pulled out of the base body 3 or the recess 9 of the base body 3 . This is only possible if the clamping screw is removed.
  • the guide blade 7 can be clamped in the recess 9 by tightening the clamping screw and the position of the guide blade can be locked in this way. This also determines the position of the hook element 5 attached to the guide bar 7 relative to the base body 3; the hook element 5 is locked.
  • the mating thread for the clamping screw (not shown) can either be formed directly into the underside of the base body 3 . It is also possible to provide a sleeve nut on the underside of the base body 3 which, together with the thread of the clamping screw, causes the guide sword 7 to be clamped.
  • clamping screw it is also possible for the clamping screw to be designed as a quick-action clamping screw, for example with a clamping lever. Such quick releases have been known in bicycles for decades.
