Definitions

  • the present invention relates to a system identified as "medicalizable automotive chairlift” for use in ambulances (hereafter referred to as PAM for short), which provides essential novelty features and important advantages over known means. and used for similar purposes in the current state of the art.
  • the invention proposes the development of a self-propelled mobile device and an associated set of anchors, so that it is fixed to the ground of the ambulance while it is in motion.
  • the purpose of the PAM is twofold: on the one hand, to serve as support and fixation for both the patient-stretcher and the various medical and instrumental equipment; on the other, allow the set consisting of the patient, stretcher and equipment can be mobilized by an external operator with safety, comfort and hardly any physical effort.
  • the mobility of the P £ M is based on the fact that it is provided with four wheels and a propellant element constituted by an electric motor coupled to a differential-differential mechanism and fed from built-in batteries; said motor can be driven at will, both in the direction of travel (forward or backward) and speed (greater or lesser) by means of conventional electrical switching elements.
  • the associated anchor set allows the PAM not to move from its parking position while the ambulance is in motion.
  • SUBSTITUTE SHEET (RULE 26)
  • the scope of the present invention is within the industry dedicated to the manufacture of auxiliary equipment for medical purposes, particularly devices and means intended to equip ambulances and the like, but without discarding their use in hospital settings.
  • the practical need to transport patients who require technical-health care en route or transport between different departments of large hospitals is generally known.
  • the ambulances that perform this type of service are equipped with a series of devices and equipment, normally located on the sides and roof of the vehicle - which provide the patient with various functions, such as monitoring of vital signs, defibrillation, assisted breathing with or without oxygen supply, aspiration, intravenous or intraarterial infusion of medications, etc.
  • the current state of the technique of transporting patients in ambulances generally consists in fixing a frame to the floor of the vehicle that serves as a base for the support and anchorage of the patient's stretcher and, at the same time, allows to locate this one at a height and inclination suitable for the treatment.
  • this frame occupies a central position in the sanitary compartment and lacks the capacity to house equipment other than the stretcher itself that it supports.
  • the maneuver of introducing and attaching the stretcher to the frame is not exempt from the risk of accidents or injuries as a result of material, imperfect or material failure.
  • SUBSTITUTE SHEET (RULE 26) Frequent physical effort that demands health personnel. In other cases, the use of special stretchers is used, although they do not require the installation of a fixed frame on the floor of the ambulance, they do not prevent the effort of dragging them by hand to the interior of the ambulance, nor do they have the ability to carry equipment doctors.
  • the aforementioned arrangement of elements implies the need to lay various cables and channels between the equipment and the patient, which makes it difficult for the movement of medical personnel around the latter in an already reduced cabin in itself and that usually travels at considerable speed.
  • the removal of the patient when the ambulance arrives at its destination implies, in many cases, the momentary interruption of the treatment or the need to transport by hand the equipment that until then was placed in their accommodation, provided that they can operate autonomously, What does not happen in all cases.
  • the present invention has been proposed as a fundamental objective, the development of a system capable not only of supporting the patient's stretcher, but also of carrying most of the necessary equipment to provide an intense and orderly and continuous attention, to mobilize the whole comfortably and effortlessly and, in short, to enable a more ergonomic and functional design of the interior of the ambulance care cell.
  • the main element of the PAM consists of a rectangular shaped frame and section constituted from a plurality of elements (metal profiles and support plate) that provide the necessary rigidity and resistance, and that incorporates a motor group, an electronic control device , preferably an electronic solid state device, and power batteries.
  • This frame moves
  • SUBSTITUTE SHEET (RULE 26) on four wheels, of which the two rear receive the movement from said motor group.
  • the latter's housing is mounted at its two ends on two support arms, each of which is fixed at its opposite end to an elastic suspension element in turn attached to the frame.
  • the other two wheels are located at the front, with rotating brackets and an elastomer bushing to absorb small shocks due to irregularities in the ground.
  • the support plate of the frame and jointly attached to the longitudinal profiles of the latter there are elements that provide support for a stretcher and that leave between the latter and the support plate an empty interior space intended to contain the various medical devices and allow the Easy access to them.
  • the design of the elements that support the stretcher provides that the latter can pivot on any of its ends - so that the inclination of the patient with respect to the horizontal plane is appropriate in those pathologies that require it - as well as being able to vary its height with respect to the ground, thus facilitating the work of health personnel and the transfer of the patient from the PAM to a hospital bed or vice versa.
  • a handle or handlebar consisting of a tubular piece with upward travel, to which the means of electric switching and motor speed control are attached and which preferably consist of "motorcycle handle” type devices, due to its easy and intuitive operation.
  • the propellant group provided for the drive of the assembly is constituted by a direct current electric motor coupled to a reduction group and a differential gear, all in the same housing. It is thus possible to drive the mobile unit at a low travel speed which, according to the preferred embodiment, is in the range of 3 to 5 km / h, and facilitate its rotation, even in very small spaces.
  • the set of anchors consists of two pieces, permanently attached to the floor of the vehicle and arranged longitudinally on it. One of them consists of a mechanism equipped with a safety bolt that automatically captures a steel pivot attached to the bottom of the PAM. The other is a top-guide that helps center and immobilize the unit in the ambulance cabin. This set of anchors prevents any displacement in the longitudinal, lateral and vertical direction of the PAM during vehicle driving.
  • FIG. 1 shows a perspective view of the medicalizable automotive stretcher device (PAM) constructed in accordance with the invention.
  • the device has in its upper part the fork pieces 2 which serve to house and anchor the transverse reinforcement bars of the stretcher.
  • the tilting forks 3 allow any of said bars to be held in a higher position with respect to the other, thus ensuring that the stretcher bends a certain predetermined angle of amplitude.
  • the plate or tray 4 equipment carrier that serves as a base of support common to medical instruments (not shown).
  • the lower part of the frame is formed by a rectangular structure 5, obtained from a plurality of profiles of different material, shape and section, on which the elastic suspension elements 6 of the motor assembly are mounted, as well as two front wheels 7 , each of which is mounted on a respective vertical axis of free rotation.
  • the forks that hold the latter incorporate an elastomeric bushing 8 designed to reduce or dampen the small shocks and vibrations that could be transmitted to the frame during the ride.
  • the housing 9 of the motor group is linked to the elastic suspension elements 6 by means of support arms (not appreciable in the Figure), while the rear wheels 10, larger in diameter than the front ones, are mounted on the ends of the motor-reducer-differential assembly.
