DESCRIPTION

Cardiac massage device Object of the invention

The object of the present invention is a novel device for performing cardiac massages during the cardiopulmonary resuscitation process. The device is foldable and detachable, which means that it can be stored and / or transported with great ease, and its operation is manual so it does not need batteries, which can be discharged, or a connection to the electricity supply network That may not be accessible.

Background of the invention

Cardiopulmonary resuscitation, or CPR, is a set of maneuvers designed to ensure the oxygenation of a person's vital organs when their blood circulation stops due to a cardiorespiratory arrest. It comprises two maneuvers, cardiac massage and artificial respiration, which must be coordinated, and which must preferably be carried out by two or more people.

Cardiac massage during a cardiopulmonary resuscitation (CPR) is an exhausting and physically very demanding process that can sometimes be extended up to hours, it being necessary to alternate between several resuscitators to avoid exhaustion until emergency services arrive, which is not always possible Well, there may not be enough health personnel at the scene of the accident or it will take a long time to get to the site. Due to this, one of the current criteria to cease the performance of a CPR is the exhaustion of the rescuer himself.

One of the main drawbacks that comes to solve the present invention is precisely that of exhaustion, since being a device that exerts pressure by means of a lever and gear system, the force necessary to exert adequate pressure is minimal, making it much more comfortable the process and being able to keep a resuscitator only giving compressions without running out for much longer.

Another drawback that is intended to circumvent this device is the fear that is often present in any person who is in need of acting as a rescuer without prior experience and without being specialized personnel. A CPR performed correctly is an aggressive process in which you have to put so much pressure on the victim's sternum for compression to be effective, that it is extremely common to end up fracturing ribs and causing other injuries, which usually causes an understandable anguish. in the resuscitator, who thinks he is doing excessive damage and ends up exerting less pressure than is required to avoid such damage. With the present invention, once calibrated and placed on the victim, the only thing that is requested. The resuscitator is to actuate a lever or crank until it stops to perform the compressions, without having to worry about the intensity or frequency, which will already be calibrated, eliminating the stress of being responsible for the damage caused.

Finally, another major problem that would come to solve is the inadequate application of the technique by untrained personnel. CPR is a process that requires a specific technique to be effective, and that very few people know for lack of access to the relevant courses taught by qualified professionals. The invention, as already mentioned in the previous paragraph, only requires its proper placement, in a simple and intuitive way, with minimal and equally simple training, and to operate a lever, so there would be no need to worry about failures more frequent, such as the inadequate position or placement of hands and arms of the resuscitator.

Description of the invention

The cardiac massage device, which is one of those used in cardiopulmonary resuscitation maneuvers, comprises:

• a flat base intended to be placed on an alien surface and under the back of the person to resuscitate,

• a folding frame, which is located on said base and which comprises one or more vertical elements attached to said base and one or more horizontal elements attached to the free end of said vertical elements; such that the union between the vertical elements and the horizontal elements makes it possible to lower the above horizontal elements on the vertical elements and the union between said vertical elements and the base allows them to be lowered on the base,

• a pusher that is intended to be in contact with the patient's chest,

• a manual drive mechanism capable of transmitting an alternative linear movement to said pusher and thus performing cardiac massage, and which is removably attached to said horizontal elements,

• means of limitation at will of the amplitude of said alternative linear movement and

• means of limitation at the will of the pressure exerted by the pusher.

Brief description of the figures

Figure 1: shows a schematic view of a perspective of the cardiac massage device.

Preferred Embodiments

Figure 1 shows a preferred embodiment of the cardiac massage device (1), which is the object of the present description, comprises a flat base (2), a folding frame (3), a pusher (8) and a mechanism (6 ) manually operated that transmits an alternative linear movement to said pusher (8).

To give a cardiac massage to a patient, the base (2) is placed under the back of the person to be resuscitated and supported on the surface, for example, the floor or a stretcher, where the patient is lying or lying, with that the vertical elements (4) are located on one of its sides and the horizontal elements (5) on its chest, later and without actuating the crank (7) and by means of the joining means the lower end of the pusher is supported on the chest of the patient, and as the stroke and the pressure generated by the mechanism are predetermined, it is only necessary to operate the crank to start the massage with the necessary frequency, which may be indicated at the base.

The pressure exerted by the pusher may be limited at the factory or by specialized personnel operating on the means of limitation at the will of the pressure, these means may be by tensioning a spring or by mechanical fuses.

Both the vertical elements and the horizontal elements can be U-section profiles made of light materials such as plastics, aluminum or other materials. Likewise, the base can be divided into two parts joined together by a hinge (9) so that it occupies less space when stored or transported.

Next, several design options are indicated that have the objectives that the invention can be adapted to the physical constitution of different people, the type of mechanism generating the alternative linear movement and the regulation of the amplitude, or stroke, of the pusher .

As there are more or less corpulent people, that is to say, they have different chest diameter, the vertical elements can be extensible and the union between the generating mechanism and the horizontal elements can allow varying the position of said generating mechanism in said horizontal elements. In the first case the vertical elements can be extensible, for example, by means of a telescopic configuration, that is to say each of the vertical elements can be formed by two or more sections that can be collected by introducing each other, or by means of a scissor configuration or any other known way of extending an element. And the variation of the position of the generating mechanism on the horizontal elements can be achieved by means of rails on which guides are slid, by means of lugs that snap into different holes or any other system existing in the market than an expert in the market. Matter can apply to solve the problem.

The mechanism for generating an alternative linear movement can be of the type comprising a pinon and a rack, of the crank rod type or of the Scottish yoke type or any other that transforms a circular movement into a linear movement. And the pusher stroke can be limited by movable stops at will, for example, by a clock-type actuator that indicates the length of the stroke or by nuts in a way that limits the depth in table drills, which restrict movement circular of the axis of the crank or the linear movement that is obtained at the exit of the generating mechanism.

Among the advantages of the invention, it is considered convenient to highlight the following:

• greater ease and efficiency in the performance of basic CPR techniques by untrained personnel,
