PREFERRED EMBODIMENT OF THE INVENTION

[0037] FIGS. 1 to 6 show two preferred embodiments of the invention in detail.

[0038] In this sense, it can be seen in the mentioned figures that the device for cardio-pulmonary resuscitation of a patient is made up of a wedge-shaped support base (1), which makes it possible to lift the patient's chest with respect to the horizontal plane, a swivel support (5) for supporting the patient's head, two lateral support elements (8), which are associated with the swivel support (5), and a mask holder (9) which is connected to the lateral support elements (8).

[0039] As can be seen in FIGS. 1 to 4, the support base (1) has guiding means (2) along which the complementary guiding means (6) of the swivel support (5) run, making it possible for the swivel support (5) to move such that it swivels on the support base (1). Likewise, the support base (1) comprises swivel elements (3) which are connected to the complementary swivel elements (7) of the swivel support (5) for fixing the position thereof, preventing the backward movement thereof.

[0040] The swivel elements (3) of the support base (1) are connected by means of a flexible polymer spring, not depicted in the mentioned figures, to the pushbutton (4) or pushbuttons. The actuation of the pushbutton (4) causes the swivel elements (3) of the support base (1) to shift, thus being disconnected from the complementary swivel elements (7) of the swivel support (5), making it possible for the swivel support (5) to move freely with respect to the support base (1).

[0041] This configuration of the support base (1) and the swivel support (5) offers two different positions of the device for cardio-pulmonary resuscitation. Said positions are a first neutral position, shown in detail in FIG. 5, in which the swivel support (5) is aligned with the horizontal plane defined by the support base (1), and a second position, shown in detail in FIG. 6, in which the swivel support (5) is swivelled, offering the required inclination with respect to the horizontal plane defined by the support base (1) to cause the hyperextension of the patient's neck and for opening the patient's airways.

[0042] The device of the invention envisages the incorporation of two lateral support elements (8), with attachment means (16) for the connection thereof to the swivel support (5) through respective notches (17) provided on each of the sides of the swivel support (5), as depicted in FIGS. 1, 3, and 4.

[0043] Additionally, the lateral support elements (8) have insertion means (15) for the introduction of the arms (10) of a mask holder (9). The arms (10) are provided with a plurality of toothed elements (11) and attached to a connector (12) with a perforation (13) for coupling a ventilation mask (14). Advantageously, the described mask holder (9) allows the use thereof in combination with any of the known manual and mechanical assisted ventilation equipment and masks.

[0044] The ends of the arms (10) of the mask holder (9) are therefore introduced in the insertion means (15) of the lateral support elements (8), the position of the mask holder (9) being vertically adjusted based on the dimensions of the patient. The toothed elements (11) are connected to inner retention means, not depicted in FIGS. 1 to 6, provided in the lateral support elements (8). The mask holder (9) is thereby associated with the lateral support elements (8), and thus with the swivel support (5).

[0045] FIGS. 1 and 2 show a first preferred embodiment according to the present invention. Specifically, FIG. 1 shows a front view of the device in a neutral position, with the lateral support elements (8) coupled in the swivel support (5), whereas FIG. 2 shows a rear view of the device in which the detail of the attachment means (16), prior to the insertion thereof in the notches (17) of the swivel support (5), is seen. As can be seen in FIG. 2, in the illustrated embodiment, the attachment means have a plurality of protrusions (22) which are connected to inner anchoring means (not depicted in the provided figures) of the swivel support (5). Therefore, once the patient has been positioned on the support base (1), the attachment means (16) are inserted in the notches (17) of the swivel support (5) based on the dimensions of the patient, as a result of the presence of the protrusions (22) and the inner anchoring means, with the lateral support elements (8) being perfectly coupled to the patient's face.

[0046] FIGS. 3 to 6 show a second preferred embodiment according to the present invention, in which the lateral support elements (8) have horizontal grooves (23) for receiving an adjuster (18) for adjusting the position of the mask holder (9). As depicted in FIGS. 3 and 4, the adjuster (18) offers insertion means (15) for the introduction of the arms (10) of the mask holder (9), as well as locking means (19) for adjusting the position of the mask holder (9) horizontally. Additionally, the lateral support elements (8) have cavities (20) complementary to the locking means (19) for adjusting the mask holder (9) horizontally. Likewise, it can be seen in FIGS. 3 and 4 that, in this second embodiment, the device incorporates a pushbutton (4) on each side, which makes it possible to perform the swivelling operation in a precise and comfortable manner.

[0047] Moreover, in the second embodiment illustrated in FIGS. 3 to 6, the swivel support (5) is prolonged until covering the occipital region of the patient's head when the patient is positioned on the device for cardio-pulmonary resuscitation. A portion of the swivel support (5) has a decreasing section in the area coinciding with the occipital region of the patient's head, such that the extent to which the attachment means (16) of the lateral support elements (8) are introduced in the notches (17) of the swivel support (5) is determined by the dimensions of the patient's head, which makes it possible for the lateral support elements (8) to be perfectly adapted to the patient's face based on the dimensions thereof.

[0048] In the event of the patient vomiting, to facilitate quickly releasing said patient and rolling him/or onto his/her side, the device envisages the incorporation of release means (21), such as a lever or pushbutton, in each of the lateral support elements (8) for the disconnection thereof from the device, as can be seen in FIGS. 3 to 6.

[0049] To achieve a quick and effective placement of the different elements making up the device in a completely symmetrical manner at both ends of the patient's head, the arms (10) of the mask holder (9) have indication means, such as pictograms, areas with a different shade, or alphanumerical codes. Therefore, when the arms (10) of the mask holder (9) are introduced in the lateral support elements (8), it is verified that the vertical adaptation of the mask holder (9) is the same for both arms (10), checking that the indication means of one of the arms (10) corresponds with the indication means of the other arm (10).

[0050] Similarly, the lateral support elements (8) have indication means, such as pictograms, areas with a different shade, or alphanumerical codes, which make it possible to verify the correct horizontal positioning of the mask holder (9).
