Device for cardiopulmonary massage and/or resuscitation

Abstract

A device for cardiopulmonary massage and/or resuscitation of a patient, which has a massage device arranged on a support board and includes a reversibly drivable massage stamp that can be positioned at a desired contact area on the thoracic cage of the patient for performing cardiopulmonary massage, and further includes a retention plate element which can be positioned on the thoracic cage of the patient at the desired contact area and which, by using at least three clamping elements engaging on its circumference, can be fixed, in particular can be connected to and braced by the support board. This has the effect that the mechanical cardiopulmonary massage can be maintained upright even during difficult transport maneuvers, since the relative position of the patient with respect to the massage device is not appreciably changed by its being clamped between the support board and the retention plate element.

DETAILED DESCRIPTION

(5) FIG. 1 shows an entire device according to the invention, labelled with 10, with the help of which a patient 11 can be transported in a lying position while simultaneously receiving cardiac massage. For this purpose, the device 10 is provided with a support board 12 on which the patient lies on his back. At the support board 12 in one of the corner areas located at the head end 13, a massage device 14 is arranged having, on a portal support that cannot be clearly seen in a top view according to FIG. 1, an arm 15 projecting above the patient's chest, which carries a reversibly drivable massage stamp 16 at its free end. The massage stamp 16 can be positioned at a desired contact area 17 to carry out the cardiopulmonary massage on the patient 11 by moving its pressure head up and down. The reaction forces, which mainly impact vertically to the patient's chest and that occur as a consequence of cardiac massage, are directly taken up by the massage device 14 into the support board 12 to which it is directly connected. As far as it is described until now, the structure of the device broadly corresponds to the one known from DE 10 2013 100 943 A1, which is incorporated by reference herewith and the disclosure of which is hereby made the subject of this application.

(6) According to the invention, a retention plate element 19 that can be positioned at the desired contact area 17 at the thoracic cage 18 of the patient 11, which has four clamping elements 20 engaging on its circumference that can be connected to and braced in the corner areas of the support board 12. For this purpose, the retention plate element 19 features four connecting elements 21, which are arranged roughly evenly and diagonally opposite each other and are aligned to the corner areas of the support board 12 where the four clamping elements 20 fastened to the corner areas of the support board can engage. The clamping elements 20 are securing straps that have hook fastening elements 22 that can be attached to the connecting elements 21 assigned to the retention plate element 19 in a detachable manner. In order to ease the connection of the hook fastening elements 22 to the associated connecting elements 21, it is preferably provided that the hook fastening elements engage with the relevant connecting elements with magnetic support.

(7) In FIG. 1 it can be seen that the retention plate element 19 has an additional connection 23 for an additional clamping element 25 guided between the legs 24 of the patient 11, the other end 26 of which is permanently sewn to a sling 27 on which the support board 12 is lying and with the help of which, the patient 11 can be carried by the emergency services over difficult terrain, such as a narrow stairwell.

(8) The arrangement according to the invention enables the patient 11 to largely maintain a consistent position in relation to the massage device 14 even during transport, in that the patient's upper body is firmly clamped between the support board 12 and the retention plate element 19 by means of clamping elements 20 operating firmly between these two parts of the device, so that he cannot slip, at least not appreciably, while he is being transported. The massage device can therefore carry out cardiac massage during transport, without the risk that the massage stamp 16 loses is position at the desired contact area (i.e. on the patient's sternum). The additional connection 23 with the additional clamping element 25 guided between the patient's legs 24, which is directly connected to the sling 27, ensures that the patient's position in relation to the sling remains largely the same and, in particular, the patient with the device placed on his upper body cannot slip forwards (e.g. left in FIG. 1) out of the sling, for example if the patient is carried feet first down a staircase by the emergency services.

(9) The retention plate element 19 is shown in more detail in FIGS. 2 and 3. As can be seen, the preferred design shown is ring-shaped with a central opening 28, which forms access for the massage stamp 16 when the retention plate element 19 is positioned at the desired contact area 17 of the patient, i.e. preferably concentric to the lower third of the sternum of the thoracic cage 18. The retention plate element 19 has an inner ring element 29 made of an elastic plastic material that is around 2 to 5 mm thick, which is covered with a high-strength fabric. Due to the comparatively large width of the ring element 29 in its radial direction, which is preferably at least 35 mm and at least 50 mm in the design shown, the retention plate element is largely inflexible in its radial direction and in its circumferential direction whereas it is malleable in a direction vertical to the patient's thoracic cage due to the comparatively low thickness, so that is can adapt to the individual anatomical conditions of the patient concerned. In the design example described and shown here, the connecting elements 21 and the additional connection 23 are located on fastening straps 31 which project radially from the retention plate element 19. For this, the fastening straps 31 comprise strips 32 made of a high-strength fabric that are wrapped around the clamped ring element 29 and whose radially protruding ends 33 are sewn together and to the connecting elements 21 or the additional connection 23 or connected in another, suitable way.

(10) The ring-shaped design of the retention plate element 19 with the central opening 28 makes positioning of the massage stamp for cardiac massage easier, by initially ensuring that the retention plate element is correctly positioned on the patient's thoracic cage and then firmly connected with the support board 12 below the patient with the help of the clamping elements 20, so that it can no longer shift to the side and firmly clamps the patient's thoracic cage between itself and the support board. It is possible to mark the ring element 29 with marking strips (not shown), for example in the area of the four fastening straps offset against each other by 90° for the clamping elements 20 to be connected to the support board or between them, which marking strips ease the correct alignment of the retention plate element concentric to the desired contact area 17, which coincides with the centre of the central opening 28, i.e. concentric to the opening 28. After correct application of the retention plate element, all that remains is for the massage stamp 16 to be positioned with its contact area centrally in the central opening 28 of the ring element 29. But it is also possible to design the retention plate element not as a ring, but closed and the contact area of the massage stamp is then placed not directly on the patient's chest, but on the upper side of the retention plate element, which freely joins in the up and down movement of the massage stamp vertically to the patient's thoracic cage due to its inherent flexibility. In such a design, it is also possible to couple the contact area of the massage stamp to the retention plate element, for example using a Velcro fastener, and in this way create a fixed connection between the massage stamp and the patient secured by the device in a direction transverse to the actuation direction of the massage stamp.
