Abstract

In a device for cardiopulmonary massage and/or resuscitation of a patient, which has a massage device (14) arranged on a support board (12) and comprising a reversibly drivable massage stamp (16) that can be positioned at a desired contact area (17) on the thoracic cage (18) of the patient (11) for performing cardiopulmonary massage, the invention proposes the provision of a retention plate element (19) which can be positioned on the thoracic cage (18) of the patient (11) at the desired contact area (17) and which, by means of at least three clamping elements (20) engaging on its circumference, can be fixed, in particular can be connected to and braced by the support board (12). This has the effect that the mechanical cardiopulmonary massage can be maintained upright even during difficult transport manoeuvres, 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.

Description

Title: Device for cardiopulmonary massage and / or resuscitation

The invention relates to a device for cardiopulmonary massage and / or resuscitation of a patient, having a massaging device connected to or connectable to a support board, which has a reversibly drivable massage stamp, which at a desired contact area on the chest of the patient for performing a cardiopulmonary massage is positionable.

Such a device is known from DE 10 2013 100 943 AI. The massaging device can be reversibly driven by a drive device in an actuating direction in the case of the known device and has a pressure surface which can be positioned on a patient's thorax at a Söll contact region on its pressure piston. Deviations of the position of the pressure surface of the massage device from a target pressure point are determined by a position sensor device, with which it is possible to change the position of the massage device and / or the pressure surface relative to the target contact area on the chest of the patient in a plane normal to the direction of actuation To determine massage device.

The well-known device in which by the connection of the massage device on the Auflagerbrett the compressive forces exerted by the massage stamp compressive forces are introduced directly into the Auflagerbrett on which the patient rests, is well suited to machine on a patient to perform a cardiac massage, as long as Device is substantially stationary, does not change the position of the device relative to a pad, so for example, a fixed mounted in an ambulance couch or at least not appreciably. Often, however, there is the problem for paramedics that they have to transport a patient, for example, from an apartment or from the place of an accident first by means of suitable carrying aids to an ambulance or a helicopter, it may well be that during this transport process, the cardiac massage is not interrupted shall be. Although the known device is quite able to continue the massage with the plunger during the transport of the patient, for example by means of a stretcher or a baby sling. It can in such transport operations but easily come to the fact that the patient lying on the support board his situation - possibly very suddenly - relative to this changed, which in practice, for example, when transporting the patient via a staircase then results in a reasonably continuous operation of the massage device is not possible because too great changes in the position of the massage device relative to the desired contact area on the chest of the patient occur and thus an efficient resuscitation is not possible. Under certain circumstances, even a risk to the patient is possible.

From DE 14 91 745 A a device for stimulating and reviving the heart and lung activity of a patient is known which has a massage unit which is connected with straps on a support-board-like shoulder rest, the massage unit on the chest of lying on the shoulder rest patient hold tight. In this device, the holding forces that occur during the cardiac massage as reaction forces, deposited on the straps in the shoulder rest, which leads to very high holding forces in the straps because of not predominantly in the direction of actuation of the massage unit going course of the straps. Nevertheless, with each pressure of the massage unit on the chest of the patient, the massage unit comes to a certain distance from the chest, which reduces the effectiveness of the chest compressions. The conditions in the transport device for a patient known from US Pat. No. 4,060,079, with which the latter can receive a cardiac pressure massage during transport with a massage device fastened by means of straps, are not very different. Also in the arrangement known from US Pat. No. 4,915,095, a cardiac massage unit is secured by means of straps on the patient's chest, which are looped around the upper body of the patient and absorb the abutment forces during the downward movement of the plunger.

The object of the invention is to improve a device of the type mentioned so that thus the machine cardiopulmonary massage can be maintained even during the explained, difficult transport measures. This object is achieved with the invention by a holding plate element which can be positioned on the desired contact region on the patient's thorax, which can be fixed by means of at least three tensioning means acting on its circumference, at least two of the three tensioning means being connectable and braceable to the support plate.

The holding plate element according to the invention makes it possible to reliably fix the patient between himself and the support board so that even with a difficult transport, such as a down carry the patient through a staircase, the position of the patient's chest relative to the Auflagerbrett not, at least not abruptly changed appreciably, so that the massaging device connected to the support board maintains its position at the desired contact area and can continue to exercise its massage during transport. The patient is with his upper body between see the Aufbrettbrett and the holding plate member by means of acting between these two components of the rescue system clamping means in fact clamped so that he can not slip to relevant extent relative to Auflagerbrett, thereby providing the desired point of application for the massage device for correct Performing the cardiac massage would change.

Preferably, the holding plate member is provided with angeord Neten at its periphery mounting tabs on which the clamping means are releasably connected. This configuration makes it possible to apply the Vorrich device quickly and precisely to the patient by placing this next to the Auflagerbrett and then the Halteplat tenelement is placed on his chest to then connect the clamping means to the mounting tabs, which firmly with their other ends on the support board or (at least in part) a sling or a stretcher carrying the stretcher can be closed to. To fix the patient between the on-board and the holding plate element then only the clamping means must be stretched.

The holding plate element may be approximately circular with a central con tact surface for the massage stamp or in a particularly preferred ring shape with a central opening for the passage of the massage stamp be designed. If the holding plate element is circular with a closed central contact surface, this is aligned on the chest of the patient so that it is as accurately as possible above the desired contact area for the massage device. The plunger of the massage device then starts on the top of the contact surface on the holding plate element. It is also possible to fix the once set position of the pressure surface of the massage device relative to the contact surface on the holding plate member by a locking means between these two surfaces, for example by a hook and loop fastener with a fleece on one and a hook and loop on the other of the two surfaces. If it is preferred, as is usually the case, that the desired desired contact area on the breastbone remains accessible, in particular visible, to the physician or paramedic during the cardiac massage, in order to allow a visual check of the correct position of the stamp, this is with the annular design the holding plate member by the annular opening formed therein easily possible, through which the massage punch on the chest of the patient can be attached.

In an advantageous embodiment of the invention, the holding plate member has four preferably uniformly distributed on its circumference arranged connection elements for four acting on corners of the Auflagerbretts clamping means. It is particularly advantageous if the holding plate element has an additional connection for an additional clamping means guided between the legs of the patient. Such an inserted between the legs of the patient auxiliary clamping means, which can be connected to its other end either also on the Aufplatzbrett or when using a baby towel, a stretcher or other carrying system, even at high tilt of the patient, for example, at Transport can come over a staircase, a safe storage of the patient, who then certainly can not slip to any significant extent relative to Auflagerbrett. In conjunction with the sling or other carrying system is also the slipping of the system consisting of patient, support board with holding plate element and massage Device against the sling or other carrying system prevented.

The tensioning means are in an advantageous embodiment of the invention tension straps with hook closure elements, which are detachably connectable with arranged on the holding plate element connection elements. It is particularly advantageous if the hook closure elements engage magnetically supported on the associated connection elements.

The holding plate element is expediently at least largely inflexible in the radial and / or circumferential direction and designed to be deformable in a direction perpendicular to the patient's ribcage. As a result, on the one hand, the clamping forces, which are exerted by the clamping means substantially in the radial direction on the holding plate element, absorb well and, on the other hand, adapt well to the anatomical shape of the thorax of the patient. The holding plate element may, for example, comprise a central ring or disc element of flexurally elastic plastic material, which is preferably covered with a high-strength fabric on which the connection elements are provided.

The connection elements and / or the additional connection can be arranged on attachment tabs which are arranged approximately radially projecting on the holding plate element.

If one wishes to use the device according to the invention in combination with a sling such that the support board is placed on top of the sling, the arrangement is preferably such that at least one clamping means engaging the slat element is connected or connectable to the sling. It is then particularly preferred for the tensioning means connected or connectable to the sling to be able to be connected between the legs of the patient and connectable to the additional connection.

Further features and advantages of the invention will become apparent from the following description and the drawing, wherein a preferred embodiment of the invention by way of example is shown in more detail. It shows: Fig.l a device according to the invention with a patient in a schematically simplified plan view;

FIG. 2 shows a preferred embodiment of the holding plate element used in the device according to FIG. 1 in a plan view; FIG. and

3 shows the subject matter of FIG. 2 in a section along the line III-III.

FIG. 1 shows a device according to the invention designated in its entirety by 10, with the aid of which a patient 11 can be transported lying while at the same time receiving a cardiac massage. The device 10 is provided for this purpose with a support board 12, on which the patient flies up with his back. On the support board 12, a massage device 14 is disposed on one of the top portions 13 located at the head end, which has a not shown in plan view of FIG. 1 portal support a projecting above the chest of the patient boom 15, the reversing at its free end drivable massage stamp 16 bears. The massage punch 16 can be positioned at a desired contact area 17 in order to carry out the cardiopulmonary massage on the patient 11 there by moving its print head up and down. The reaction forces acting essentially perpendicularly to the patient's chest, which occur as a result of the cardiac pressure massage, are thereby deposited directly by the massage device 14, which is connected directly to the support board 12. As far as described so far, the device in its construction essentially corresponds to that, as it is known from DE 10 2013 100 943 AI, to which reference is hereby made and the disclosure of which is hereby made the subject of the present application.

According to the invention, a holding plate element 19 which can be positioned on the thorax 18 of the patient 11 at the desired contact region 17 is provided, which can be connected and braced with four supporting devices 20 acting on its circumference with the supporting board 12 in its corner regions. For this purpose, the holding plate element 19 has four diagonally opposite each other at its circumference, distributed uniformly around its circumference. ing and aligned to the corner regions of the Auflagerbretts 12 connecting elements 21, where the four attached to the corner regions of the Auflagerbretts clamping means 20 can attack. The tensioning means 20 are tension straps which are provided with hook closure elements 22 which can be detachably attached to the connecting elements 21 arranged on the holding plate element 19 and assigned to them. In order to facilitate the connection of the hook closure elements 22 to the associated connection elements 21, it is preferably provided that the hook closure elements engage in a magnet-assisted manner on the corresponding connection elements.

It can be seen in FIG. 1 that the holding plate element 19 has an additional connection 23 for an additional clamping means 25 guided between the legs 24 of the patient 11, the other end 26 of which is sewn firmly to a sling 27 on which the support board 12 flies and with whose help the patient 11 can be carried by his rescuers through difficult terrain such as a narrow staircase.

The inventive arrangement makes it possible to position the patient 11 during transportation relative to the massaging device 14 substantially in a constant position by the upper body of the patient between the support board 12 and the holding plate member 19 by means of acting between these two device parts clamping means 20 fixed is clamped so that he can not or at least not significantly slip while the patient is being transported. The massage device can therefore also perform the cardiac massage during transport without the risk that the massage stamp 16 will lose its position at the desired contact area (ie at the sternum of the patient). The additional connection 23 with the additional clamping means 25 guided between the legs 24 of the patient, which is fastened directly to the sling 27, ensures that the position of the patient also remains largely the same relative to the sling, and in particular the patient with his on the upper body applied device can not slide forward (ie left in Fig.l) from the sling, for example when the patient is carried by his rescuers one foot down the stairs.

The holding plate member 19 is shown in more detail in Figs. 2 and 3. As can be seen, in the preferred embodiment shown, it is configured annularly with a central opening 28 which forms a passage for the massage punch 16 when the holding plate element 19 at the target contact area 17 of the patient, ie preferably concentric to the lower sternum third of Chest 18 is positioned. The holding plate element 19 has an inner ring element 29 made of an approximately 2 to 5 mm thick, flexurally elastic plastic material, which is covered with a high-strength fabric 30. Due to the comparatively large width of the ring element 29 in its radial direction, which is preferably at least 35 mm and in the illustrated embodiment at least 50 mm, the holding plate element in its radial direction and also in its circumferential direction is largely inflexible, due to the relatively small thickness, however, in A direction perpendicular to the rib cage of the patient deformable so that it can adapt to the individual anatomical conditions in the patient concerned. In the exemplary embodiment described and illustrated here, the connection elements 21 and the additional connection 23 are arranged on fastening lugs 31, which are arranged so as to protrude radially on the holding plate element 19. For this purpose, the fastening tabs 31 consist of strips 32 made of a high-strength fabric, which are looped around the covered ring element 29 and their then radially outwardly projecting ends 33 sewn together and with the connecting elements 21 and the additional terminal 23 or connected in any other suitable manner.

The annular configuration of the holding plate member 19 with the central opening 28 facilitates the positioning of the massage stamp for cardiac massage by first the holding plate member correctly positioned on the patient's rib cage and then firmly connected to the lying under the patient support board 12 by means of the clamping means 20, so that it can not move laterally and firmly clamps the patient's chest between itself and the support board. It is possible, for example, for the ring element 29 to be wise in the range of four offset by 90 ° to each other arranged mounting tabs for the to be connected to the support board clamping means 20 or between them with marking lines (not shown) to facilitate the correct alignment of the holding plate member concentric with the target contact area 17, with the center the central opening 28 coincides, that is concentric with the opening 28. After the correct attachment of the holding plate element then only the massage punch 16 with its pressure surface must be positioned centrally in the central opening 28 of the ring member 29. But it is also possible, the retaining plate member is not ring-shaped, but designed to design closed and the pressure surface of the massage stamp then not directly on the chest of the patient, but the top of the holding plate member to set the up and down movement of the massage stamp due to the inherent flexibility in the direction perpendicular to the patient's chest. In such an embodiment, it is also possible to couple the massage stamp on its pressure surface, for example by means of a hook and loop fastener with the holding plate member and in this way to create a firm connection between the massage punch and the patient practically clamped by the device in a direction transverse to the direction of actuation of the massage punch ,
