DESCRIPTION

MEDICAL DEVICE FOR AID IN POSITIONING SIDE DEBT INDIVIDUALS

Field of the invention

Technical field to which the invention belongs

The present invention relates to a medical device for assisting in positioning individuals in lateral decubitus.

State of the art

The medical device to be protected allows the health care worker to transfer the individual from the supine position to the lateral supine position with less effort. This effort reduction is due to a rotation of the individual using a lever system, consisting of a T-frame and scapular support, which after rotation supports the individual in the lateral position safely and comfortably. From the point of view of the caregiver this device allows access to the dorsal area of the individual, keeping him in a safe position and without additional effort of the caregiver while providing care.

The existing solution is a wedge cushion as claimed in CN 201806868 U, which is positioned on the bed and which supports the individual in the lateral position, but which does not aid in the positioning process. There are several ineffective attempts at problem solving, such as a device for holding the individual in the lateral position with a rod of adjustable length between plates _. as claimed in CN patent 201.996762 U; a system that tilts half of a board on the bed by a crank-driven crane; as claimed in WO 2010091375 A1; an electromechanical system attached to a sheet for rotating the subject on the bed as claimed in US 5673443 A; and a plate positioned underneath the displaceable subject and sloping to turn and hold in the lateral position on the bed with front and back supports as claimed in US Patent 20140182062 A1. The reasons why these Ineffective attempts to solve the problem are that they do not assist in the process of positioning individuals in the lateral position or guaranteeing the safety of the individual in that position, in the case of patent application CN 201806868 U and patent application CN 201996762 U, and therefore, they do not reduce the effort of this procedure in the case of patent application WO 2010091375 A1 and US patent application 5673443 A. Moreover, they are complex, large systems and, in the case of US patent application 20140182062 A1, device covers much of the individual's body and needs large beds.

The device to be protected addresses the problem by offering a simple and modular solution, enhancing comfort and a sense of security. The fact that it is simple makes it easy for the healthcare provider to learn to use the technology and the fact that it is modular makes it easy to repair and industrially capable to produce. The feeling of comfort is that it is not an invasive procedure and can support the individual throughout the procedure. Safety is important since, with the wet sponge method, the individual is constantly in an unbalanced position requiring the health care worker to support him with one hand or the individual to cling to the bed or even the assistant. Cheers. The control board (1) of the device has a length of between 25 and 150 cm and a width of not more than 70 cm, which allows it to be easily carried by the healthcare provider between homes without having to make changes in space or bed.

The reduction of effort related to the positioning of the individual during care leads to the improvement of the health and safety standards of the health aids as it should lead to a reduction in the number of injuries to which they are normally subjected.

The device can be used on either the left or right side of the bedridden individual by just changing the arm where the device is positioned.

For this purpose, the device is based on a "Τ" structure, composed of the support plate (2) and the control plate (1), and a scapular support, composed of the circular section shaft (8) and the plate. scapular (10). This device uses the scapular support together with the T-frame to transfer the individual from the supine to the lateral position and securely support it in that position.

The fact that the structure is simple and composed of parts whose production is not complex allows the device to be produced in an injection mold and on a large scale.

Summary of the invention

The present invention relates to a medical device for assisting the positioning of individuals in supine to lateral decubitus and has the object of reducing the effort that the health assistant has to exert in this procedure, as well as keeping the individual in the position of lateral position only with the device stand.

For this, it is based on a "T" structure consisting of the support plate (2) and the control plate (1), and a scapular support consisting of the circular section shaft (8) and the scapular plate (10).

During use of the device, the scapular plate (10) should be placed under the shoulder blade of the subject and the circular section shaft (8) should be between the arm and trunk thereof. Then the T-frame must be positioned so that the circular section shaft (8) fits into the holes in the control plate (1) and the support plate (2) is between the arm and the trunk. of the individual. The health care provider should apply an upward force to initiate rotation of the individual's torso while using the other hand to ensure the rotation of the hips.

The process should end with the subject in the lateral position and supported by the T-frame on the support plate (2) and against the control plate (1). At this point it is possible to remove the pins (9) from the circular sectional shaft (8) which is placed in the hole of the circular sectional shaft (8) just above the control plate (1) and further remove the scapular support allowing full access to the dorsal zone of the individual.

Detailed Description of the Invention

The medical device to assist in the positioning of individuals in lateral decubitus consists of the following components:

1) "T" structure, consisting of the following components:

The. Control board (1);

B. Support plate (2), ·

ç. Two connecting plates (3);

d. Four screws (4);

and. Two fixed pins (5), ·

f. Two Retractable Pins (6) 2) At least one pillow (7).

3) Scapular Support, consisting of the following components:

The. Circular Shaft (85;

B . Two pins (9) of the circular section shaft (8); ç. Scapular plate (10);

The present invention allows a satellite helper to transfer an individual from the supine to the lateral position in a comfortable and safe manner. The control plate (1) is positioned in contact with the chest area of the subject. It has a length between 25 and 150 cm.

At one end of the control board (1) there is a handle and at the other end is the connection to the support plate (2). The length of the control plate (1) influences the strength that the health care worker needs to change the position of the individual from supine to lateral decubitus, as the longer the control plate (1), the shorter will be the force required to effect the rotational motion.

Through holes in the control plate (1) allow the health care provider to control the distance from the circular section shaft (8) to the support plate (2), enabling the use of this device in individuals with different chest widths. These holes pass through the control plate (1) in the direction of their thickness.

The control plate (1) has four side holes (two on each side) at the opposite end of the handle to secure the two connecting plates (3),

The support plate (2) promotes, together with the scapular support., The rotation and final positioning in lateral decubitus.

Prior to the lateral decubitus rotation movement, the support plate (2) is next to and attached to the trunk of the individual. Rotation of the subject with the device causes the support plate (2) to be, at the end of rotation, below the subject. Between the support plate (2) and the trunk, a pillow (?) Can be placed to increase the comfort of the individual during the procedure. The connection between the control board (1) and the support plate (2) is made by two connecting plates (3), four screws (4), two fixed pins (5) and two retractable pins (6). This connection allows to control the angle between the support plate (2) and the control plate (15), allowing the support plate (2) and the control plate (15) to be parallel or perpendicular, depending on the user's need.

The plates are placed parallel to facilitate transport. To perform the procedure, they are placed at an angle between 70 ° and 110 °.

The two T-frame connection plates (3) may have several holes, but need at least two to connect to the control plate (1) and two to connect to the support plate (2). ). On each side of the control board (1) two of the four screws (4) are connected and to the support plate (2) one of the two fixed pins (5) and one of the two retractable pins (65) are connected.

The two connecting plates (3) are designed to connect the control plate (15 and the support plate (25) without endangering the comfort or safety of the individual. To this end, the two connecting plates (3) are so that when the device is mounted, the two fixed pins (5) and the two retractable pins (6) are at a height higher than the control board (1). the connection between the support plate (25 and the connection plates (35) remains in the support plate sliding rails (2) and maintain the connection between the control board (1) and the support board (2).

There are two retractable pins (6.) which, when positioned in the plate hole inside the support plate sliding holes (2), allow the height of the control plate (1) and the angle between the two to be defined. plates.

For this purpose a sliding chute was designed in the thickness of the support plate (2). The two fixed pins (5) and the two retractable pins (6) are on the slide rail when using the device to perform the procedure. The fact that the two retractable pins (6) can be detached from the slide rail enables the control plate (1) and the support plate (2) to vary the angles of each other. The connecting plates (3) may be designed to define the angles between the support plate (2) and the control plate (1). Along the slide rail there are holes into which the two retractable pins (6) fit together and thus define the location of the connector plate (3) relative to the support plate (2). In this way it is possible to adjust the height of the control plate (1) depending on the height of the chest area of the subject,

The cushion (7) is coated with a washable, easy to clean and waterproof fabric. It has a strap to be fitted to the control plate (15 and the support plate (2)) and can be removed.

The circular section shaft (8) is positioned in one of the through holes of the control plate (1) taking into account the width of the subject's chest area. The circular section shaft (8) is fixed to the plate by two pins (9) of the circular section shaft (8), one positioned in the hole just below the control plate (1) and the other just above the control plate. (1) . The circular section shaft (8) has through holes with an equal distance between them of absolute value greater than or equal to the thickness of the control plate (1).

The fact that it is circular allows it to rotate and provide access to the dorsal area of the individual.

The pins (9) of the circular section shaft (8) consist of the cylindrical pin and a half-moon piece, which fixes the movement of the circular section shaft (8) towards the thickness of the control board (1). .

The half-moon part has an inner diameter equal to the outer diameter of the circular section shaft (8),

The use of two pins (9) of the circular section shaft (8) allows the movement of the control plate (1) to be restricted along the circular section shaft (8). One of the two pins (9) of the circular section shaft (8) should be placed in the hole of the circular section shaft (8) just below the control plate (1) and one in the hole immediately above.

This restriction of movement of the control plate (1) is essential to enable force to be applied to the scapular support responsible for the rotation of the subject.

The scapular plate 10 is a plate for supporting the individual in the scapular zone. This plate is fixed to the circular section shaft (8) by tightening. In this way this component always follows the rotational movement of the circular section shaft (8).

The process of changing from supine to lateral decubitus position begins with the individual in supine position.

Next, the health care professional should place the shoulder support so that the shoulder plate (10) is positioned between the support surface and the subject's shoulder area and the circular section shaft (8) is between his arm and the shoulder. your trunk. The hand opposite the place where the scapular support was placed is positioned under the subject's head so as not to prevent rotational movement. Additionally, the leg on the side on which the support was positioned should be crossed over the other to facilitate rotation of the subject.

The T-frame should be placed so that the control plate (1) is over the subject's chest area and the support plate (2) is in contact with its trunk. Finally, the health care professional should use the handle to initiate the rotational movement in order to finish the movement.
