Abstract

A Cardiac Pulmonary Resuscitation (CPR) device (CPD) for performing CPR on a patient (PT). A supporting structure (L 1, L 2, F) with two legs (L 1, L 2 ) shaped to accommodate space for the patient's (PT) thorax between them. The legs (L 1, L 2 ) have clamp mechanisms (CL 1, CL 2 ) to allow clamping onto a backboard (BB). A compression box (CB) with a plunger mechanism (PM) with a contact pad (CP) projecting downwards from the enclosure (CS), and a processor (P) for controlling the plunger mechanism (PM) to perform CPR on the patient (PT) in an automatic manner. A height adjustment mechanism (H) is used to fix a height (h) of the compression box (CB) relative to the supporting structure (L 1, L 2, F). The height adjustment mechanism (H) can allow the compression box (CB) to move in relation to the supporting structure (L 1, L 2, F) in a first operating state, by help of gravity. Hereby, the compression box (CB) can enter a height (H) where the contact pad is in contact with the patient's (PT) chest, preferably within a predetermined contact force range, upon clamping of the supporting structure (L 1, L 2, F) onto the backboard (BB). Hereby, the height and contact force parameters are inherently set automatically by the device, when the operator has clamped the CPR device (CPD) onto the backboard (BB). This setup task is easy for the operator, time without CPR can be saved, and CPR can be initiated with a correct contact force.

First claim

1 . A Cardiac Pulmonary Resuscitation device arranged to perform Cardiac Pulmonary Resuscitation on a patient, the device comprising:
a supporting structure comprising first and second legs shaped to accommodate space for the patient's thorax between the first and second legs, wherein the first and second legs each has a clamp mechanism arranged for engagement with corresponding clamp mechanisms on each side of an associated backboard, so as to allow an operator to clamp the supporting structure onto the associated backboard, a compression box comprising an enclosure containing:
a plunger mechanism with a contact pad projecting downwards from the enclosure, and arranged to provide a chest compression force to the patient's chest, and
a processor arranged to control the plunger mechanism to perform Cardiac Pulmonary Resuscitation on the patient, and
the device further comprising: a height adjustment mechanism arranged to fix a height of the compression box relative to the supporting structure, wherein in a first operating state of the device, upon clamping of the supporting structure onto the associated backboard, the height adjustment mechanism is arranged to allow the compression box to slide by gravity in relation to the supporting structure, so as to press the contact pad against the patient's chest with a force determined by the mass of the compression box, and a spring mechanism arranged to force the compression box downwards, so as to press the contact pad against the patient's chest with a predetermined force, in the first operating state.

2 . Device according to claim 1 , wherein the height adjustment mechanism is arranged to fix a height of the compression box relative to the supporting structure, in a second operating state.

3 . Device according to claim 2 , wherein the processor is arranged to enter the second operating state in response to one of: an input from the operator, and an input from a sensor informing the processor that the supporting structure has been clamped onto the associated backboard.

4 . Device according to claim 1 , wherein the processor is arranged to automatically initiate a Cardiac Pulmonary Resuscitation sequence after the height adjustment mechanism has fixed the height of the compression box relative to the supporting structure.

5 . Device according to claim 1 , wherein the height adjustment mechanism is arranged to fix a height of the compression box relative to the supporting structure in one of a plurality of possible height positions.

6 . Device according to claim 1 , wherein the height adjustment mechanism is arranged to fix a height of the compression box relative to the supporting structure in a position corresponding to an actual height position of the compression box, upon activation of the device.

7 . Device according to claim 1 , wherein the height adjustment mechanism comprises a locking pin arrangement arranged to fix a height of the compression box relative to the supporting structure, in one of a limited number of height positions.

8 . Device according to claim 1 , wherein the height adjustment mechanism is arranged to fix a height of the compression box relative to the supporting structure, in response to an output from the processor.

9 . Device according to claim 1 , wherein the height adjustment mechanism is arranged to release the compression box from a fixed height position relative to the supporting structure, in response to an output from the processor.

10 . Device according to claim 9 , wherein the processor generates said output in response to a detected force applied to the patient's chest being below a predetermined threshold value.

11 . Device according to claim 1 , wherein the supporting structure comprises a frame structure rigidly connected to the first and second legs, so as to form a rigid supporting structure, and wherein the compression box is arranged to slide inside the frame.

12 . Device according to claim 1 , wherein the height adjustment mechanism is positioned at least partly inside structures forming the first and second legs.

13 . A method for initial setup of a device for performing Cardiac Pulmonary Resuscitation on a patient, the device comprising a supporting structure comprising first and second legs shaped to accommodate space for the patient's thorax between the first and second legs, a compression box comprising an enclosure containing: a plunger mechanism with a contact pad projecting downwards from the enclosure, and arranged to provide a chest compression force to the patient's chest, and a processor arranged to control the plunger mechanism to perform Cardiac Pulmonary Resuscitation on the patient (PT), a height adjustment mechanism, and a spring mechanism
entering a first operating state of the device, wherein the height adjustment mechanism is arranged to allow the compression box to slide by gravity in relation to the supporting structure with a force determined by the mass of the compression box, and the spring mechanism is arranged to force the compression box downwards so as to press the contact pad against the patient's chest with a predetermined force, in the first operating state, manually clamping the supporting structure onto an associated backboard, and fixing a height of the compression box by means of the height adjustment mechanism and the spring mechanism after the supporting structure has been clamped onto the associated backboard.
