Description

DESCRIPTION

Directional Stretcher

SECTOR OF THE TECHNIQUE

The present invention relates to a mobile stretcher, directional, for example, for movements inside a hospital. It has improvements in terms of driving that facilitates travel.

It is applicable in the field of medicine and the manufacture of medical equipment.

STATE OF THE TECHNIQUE

For the transfer of patients and patients to hospitals it is common to place them on stretchers formed by an upper panel, generally adjustable in many ways by means of motors and actuators, carried by a structure with four wheels and at least one brake. These wheels usually correspond to three steerable wheels (crazy) and a directional wheel.

In the case of emergencies or minor surgery operations, the space designated for patients (boxes, operating room ...) is reduced and several patients usually go through these places, so the risk of crossing two stretchers is high.

The large size of the stretcher and its weight makes maneuverability suffer, so those in charge of moving patients need a lot of practice to pass through narrow places, c or d or s. without hitting the walls or frames. It often implies that two people have to occupy these transfers, increasing the cost of personnel. It is necessary to improve the maneuverability of the stretchers to facilitate these transfers.

The applicant knows no solution similar to the invention.

BRIEF EXPLANATION OF THE INVENTION

The invention consists of a stretcher according to the claims. Its different embodiments solve the problems of the state of the art.

The stretcher is of the type that has a top board where the patient is placed, and which is often adjustable, carried by a structure that involves first adjustable wheels (crazy) and second wheels equally orientable at opposite ends of the stretcher. In addition, the structure also includes auxiliary directional wheels, located between the first wheels and the second wheels, but closer to the first wheels than to the second wheels.

These auxiliary wheels can be larger in diameter than the first wheels and the second wheels.

It is preferred to place or mount the locking brake on the auxiliary wheels, more accessible from both ends of the stretcher. This locking brake will be accessible from both sides of the stretcher, for which it will act through a simultaneous pedal (one lever on each wheel, mechanically connected with the other so that they are always activated or deactivated at the same time).

Other variants will be described later.

DESCRIPTION OF THE DRAWINGS

For a better understanding of the invention, the following figure is included.

EMBODIMENTS OF THE INVENTION

Next, an embodiment of the invention will be briefly described as an illustrative and non-limiting example thereof.

The embodiment shown in the figures corresponds to a stretcher of the type formed by an upper board (1) carried by a structure (2) with a series of wheels (3,4,5) grouped in pairs. In the case shown, the top board (1) is padded and has railings, at least one of which is foldable. It also carries a handle that indicates the back of the stretcher. This handle will be where you push or drag the only person needed to move the stretcher.

For its part, the preferred structure (2) is an arm with several pneumatic cylinders, but other solutions are possible. The arm solution is preferred because the moment of inertia and the total mass are reduced, facilitating maneuverability.

The wheels (3,4,5) are grouped into first wheels (3) at one end of the stretcher, second wheels (4) at the opposite end, and auxiliary wheels (5). Generally the first wheels (3) correspond to the area through which the patient places his feet, but it is not essential. The first wheels (3) and the second wheels (4) are usually adjustable, of the type called “caster in English.

The auxiliary wheels (5) are located closer to the first wheels (3) than to the second wheels (4). For example, they may be located one third of the total length of the first wheels (3). Thus, the distance between the auxiliary wheels (5) and the first wheels (3) is half the distance between the auxiliary wheels (5) and the second wheels (4).

The auxiliary wheels (5) are directional and incorporate the brake (6) of the stretcher, thus allowing it to be more easily accessible from any point of the stretcher. The brake (6) is arranged on both auxiliary wheels (5) so that they both brake or release both.

In the embodiment shown the auxiliary wheels (5) have a diameter greater than the first wheels (3) and second wheels (4). For example, it can be 50% higher.

In use, and under normal transport conditions, the stretcher is driven so that the first wheels (3) are positioned ahead, closely followed by the auxiliary wheels (5).
