OBJECT OF THE INVENTION

The invention, - as expressed in the statement of the present specification, refers to a stretcher-crane for transfer of bedridden persons that contributes to the function to which advantages and characteristics are destined, in addition to others inherent to its organization and constitution, which will be described in detail later, and that represent an innovative improvement to what is already known in this field.

More specifically, the object of the invention consists of a stretcher whose structure and special configuration are specially designed to mechanically enable translation or bedridden transfer operations between beds, stretchers or operating tables, with the minimum space requirements free and fast and convenient for both the personnel performing the operation and for the assisted person.

SCOPE

The field of application of the present invention is that of the industry destined to the manufacture of medical and hospital equipment, instruments, mechanisms and / or elements.

BACKGROUND OF THE INVENTION The work of health or geriatric care requires the realization of transfers between beds and stretchers for transport, assistance or cleaning operations of bedridden persons.

Currently these transfers are made in various ways, although by way of generalization we can summarize them in:

a) Mechanical transfer:

It is carried out using a crane or a fixed bed lifting system, with which it is maneuvered to deposit it on a stretcher or bathtub depending on the assistance provided.

To raise the bed it is necessary to place a harness. In the market there is a wide variety of harnesses depending on the type of assistance, weight of the person, lifting characteristics, etc.

The use of the crane requires a maneuver-free space next to the bed and also a space to maneuver with the stretcher. The use of fixed suspension means, currently in a small minority, allows the maneuvering needs to be lower by requiring only space for the stretcher, although its implementation is complicated and requires prior planning and design of buildings and structures.

Advantages :

• The use of mechanical means avoids part of the overexertion Disadvantages:

• The rooms must have large open spaces to allow maneuvers with stretchers and cranes

• Harness placement and removal slows maneuvers, which encourages sometimes unsafe practices to complete the operation in time.

Manual transfer

It is done using a base that slides on the bed or stretcher or rises slightly on the transfer.

The bases used are varied, the most commonly used being the removable rigid stretchers in the emergency operations and the "transfers" or the so-called interlocks in which they are carried out on a scheduled basis.

The operation involves placing the transfer element under the bedridden person and joining the bed and the stretcher, the two stretchers or the bed and the operating table and the personnel to perform the operation will be placed on the opposite side of the origin of the transfer. In order to move the person, the transfer element will be firmly held and pulled by the person until the operation is finished.

Advantages:

• Minimum needs for free space • Speed of system placement and operation operations

Disadvantages:

• Use of physical force with frequent injuries and disorders in people who perform the work.

The observation of the methods and the advantages and disadvantages associated with each of them favors the approach of a system that combines these advantages and avoids the inconveniences.

EXPLANATION OF THE INVENTION

Thus, the stretcher that the invention proposes, constitutes in itself an obvious novelty within its field of application, since in the light of its use a practical and especially effective means for bidirectional transfer of people between beds and stretchers of the type that concerns here.

To do this, and specifically, the stretcher that the present invention advocates consists of a removable rigid base, on which the bedridden person, similar to the existing ones, will be placed, which incorporates an innovative transfer system.

Said system, allows both to attract the rigid base and push it to deposit it in the bed, operating table, etc., by having two profiles that are articulated together at one of its ends to a lower support coupled to the stretcher , so that they pivot on the mechanism of actuation thereof, turning its turning movement into a translation movement, allowing both to attract and push said rigid base effortlessly.

The aforementioned profiles attached to the support, as described, are joined at their opposite end by means of metal parts, which we will designate hereinafter as translation elements, which move and run through two rails provided for that purpose on the sides of the rigid base.

In this way, the described system is assimilated in its operation to a scissor, the profiles are fixed in the actuating organs at one end, so that its circular movement causes them to open and close assimilating the said scissor movement, being able to be its electric and hydraulic drive, and it is advantageously mounted on the side of the stretcher, with the actuators on one side.

It should be noted that the operation of passing bed, stretcher or operating table to the equipment of the invention does not present any stability problem, since the same sense of movement contributes to give solidity to the assembly, while the opposite direction operation favors the separation of both elements, so that the structure of the base of the device itself will be provided with at least two elements (one at each end) hook type to provide solidity to the assembly during the transfer operation.

Logically, the device of the invention admits a large number of technical solutions that make it possible to adapt to any transport base, which however must meet minimum requirements, such as:

Allow the vertical movement of the stretcher to guarantee both the adequate height of the work plane and the adaptation to all situations where it is necessary to carry out the transfer.

A probe will be provided to determine the height of the bed, stretcher or operating table where the transfer operation is going to be carried out to avoid accidents.

It will also allow tilting the stretcher to facilitate the evacuation of water if used as a bathtub.

The invention optionally provides several levels of motorization, from the most basic that has automated the transfer and lifting and tilting system, basic stretcher operations, to an integral motorization that allows total mobility without effort.

Finally, the incorporation to the stretcher of the invention of an automatic system that allows to bring the structure to the bed automatically, allowing automotive displacement, with the incorporation of a routing system based on the use thereof is also provided alternately of a gyroscopic system, so that the operators who handle the stretcher only have to turn the stretcher itself and the system automatically positions the steering and traction system with minimal effort. All the necessary motors and mechanisms, as well as the system of power batteries that incorporates the stretcher-crane will be advantageously designed for use in a humid environment, resulting in its suitable use for such conditions.

The new stretcher-crane for translation of bedridden people represents, therefore, an innovative structure of structural and constitutive characteristics unknown until now for this purpose, reasons that together with its practical utility, provide it with sufficient foundation to obtain the privilege of exclusivity that It is requested.
