说明书全文 | The invention, as expressed in the title of this specification, refers to a safety device for ambulance medical personnel. More precisely, the object of the invention focuses on a safety device specially designed to serve as a securing element for ambulance medical personnel while performing emergency actions on the patient transferred, preventing the medical personnel from being injured or hit by hard elements in the interior of the ambulance or being thrown out of it; since medical personnel have to work standing over the patient, they are therefore not able to conveniently fasten seat belts, being said device also designed to allow such work to be performed with sufficient freedom of movement within the space of the ambulance. The scope of the present invention falls within the technical sector of the industry dedicated to the manufacture of motor vehicle accessories, particularly ambulances. As is known, during patient ambulance transfer, it is common that urgent actions be taken on the patient, which for whatever reason, cannot wait for their arrival at the hospital to which they are to be taken. In such cases, medical personnel attending the patient are forced to release their restraint and abandon their seats to stand and move around inside the ambulance cabin in response to emergency needs. This means that in the case of a collision or simply a sudden harsh or unforeseen braking, the medical staff are completely unprotected and at risk, and may themselves suffer cuts and bruises that may be more or less severe and would be desirably avoided. This is thus the essential objective of this invention, on which it is noted that at present, and with respect to current technological developments, the applicant is not aware of any other safety device which presents such an application, nor that has the technical, structural and constitutive features similar to that which is advocated here; being the characteristic details which distinguish it, adequately contained in the final claims of the present specification. Therefore, the safety device for ambulance medical personnel proposed by the invention is set to be a remarkable novelty in its specific field and with respect to current technological developments, whereby, through its implementation will undoubtedly successfully reach the ideal objectives previously mentioned. In concrete terms, the device advocated consists essentially of a guide that is longitudinally fixed to the roof of the ambulance cabin and supports a slide carriage which, with straps, is attached to the medical personnel, allowing complete freedom of movement within the ambulance's assistance cabin. Also, within the said guide there is a grooved rod which linked to said slide carriage, extends from one end to the other of the guide and constitutes the half anchor that locks the device's brake system, which consists of brake plates fitted with a spring and connected in a hook like way in the slide carriage, acting similarly to the system incorporated in safety belts; that is, with smooth movements the brake system does not activate and in the case of a collision or sudden braking, the brake system is triggered and locks onto the aforementioned grooved rod. In turn, from these brake plates hang two lines that are fastened to a harness that the medical staff must wear to secure the shoulders and the pelvis. It must be noted that in the case of emergency ambulances or the like, which require the presence of two medical staff, the possibility of placing two parallel and independent safety devices to secure both health workers, is contemplated. The new safety device for ambulance medical personnel therefore presents innovative structural and constitutive features previously unknown for such purposes. These reasons linked to its practical utility endow the device with sufficient grounds for obtaining the privilege of exclusivity requested. To complement the description being made and in order to better help understand the characteristics of the invention, the present specification is accompanied, as an integral part of it, by a set of drawings in which for illustrative and non limiting purposes the following have been represented:
In view of the aforementioned figures, and with respect to the numbering adopted, one can observe in them the preferred embodiment of the invention, whose main constituent parts and elements are described below in detail. Thus, as shown in these figures, the device (1) in question comprises a guide (2), destined to be fixed longitudinally to the roof of the ambulance cabin, which, as can be seen in For its part, the upper flat-bar (3) has several perforations (7) that will be the anchor points of the guide (2) to the ambulance body roll bars, with the dimensions of this guide (2) adjusted to the ambulance cabin, characteristically about 140 cm in length. Within said guide (2), the device features a grooved rod (8) through its entire length, which is fixed to the guide (2) by its insertion in the provided openings (9) found in the vertical segments (6) at either end of it (since the grooved rod is practically the same length as the guide), being fixed to the guide (2) by means of their respective pairs of nuts (10) inserted in their threaded ends. Continuing with the invention, the device has a slide carriage (11) that has several pairs of wheels (12) which run along the interior of the guide (2), from one end to the other, and rest on the two sides of the lower flat-bar (4). This slide carriage (11), as shown in One must note that the slide carriage (11) preferably has three pairs of rolling wheels, where each pair of wheels is joined together with a washered nut; existing between the wheels and metal plate housing (13) some short lipped washers (16) (small external diameter washers), to allow rotation of the wheel and a central separation sleeve (17). Inside the slide carriage (11) there are also two separate articulated brake plates (18), which fixed to the slide carriage (11), hang protruding from the slot (5) of the lower flat-bar (4) of the guide (2), acting in a similar way to the system found in safety belts, and consisting, as shown in Thus, as shown in Moreover, the security lines (25) that hang from these brake plates (18), go on to secure a harness (not shown), which the medical personnel must wear and, which preferably, will be of the type that secures the shoulders and pelvis. Thus, the functioning of the device (1) is as follows: the medical staff must wear the full body harness, pelvis-thorax, which has some rings to which the hooks of the security lines (25) that hang from the brake plates (18) of the device, are attached. The brake plates (18) are attached to the slide carriage (11) of the system, which allows the anteroposterior movement (longitudinal displacement) within the ambulance's assistance cabin of the medical staff, without them bodily touching either the front nor the rear of the cabin, but regulating the length of the security line so that the personnel can touch with their hands each accessible corner of the assistance cabin. When there is a sudden braking or collision, the medical personnel lose their balance and the body tends to continue the movement it had (inertia); this type of involuntary movement is sudden and harsh, and it is precisely this that triggers the braking system, preventing the medical staff from being propelled towards the anterior or posterior walls of the cabin. To summarise then, the device (1) advocated is suitable as a fastening element for ambulance medical personnel whilst performing emergency actions on the patient being transferred, enabling the work to take place with sufficient freedom of movement within the ambulance space, where the device is distinguished by the fact that it comprises at least one guide (2) that attached lengthwise to the interior of the ambulance cabin roof, supports at least one slide carriage (11) which, with security lines (25) are attached to the medical staff via a harness that is worn, and where there exists a braking system consisting of brake plates (18) equipped with a spring (23) which are connected in a hook like way in the slide carriage (11), whose braking system acts similarly to the safety belts system; that is to say, with smooth movements it does not activate and in the case of a collision or sudden braking it is triggered off, thus preventing the movement of the device. Having sufficiently described the nature of the present invention as well as how to implement the device, it is not considered necessary to extend the explanation any further, since any expert on the matter will understand its scope and the advantages derived from it. It is also noted that, in its essence, the device described by way of example may be implemented in other embodiments that differ in detail, and which will be equally protected by the claim, provided that its fundamental principle is not altered, changed or modified. |
