Description

Arrangement and system for cardiac care training

TECHNICAL FIELD

The present disclosure relates to auxiliary arrangements and systems for cardiac care training, e.g., cardiopulmonary resuscitation (CPR) and emergency cardiac care (ECC) training using a defibrillator.

BACKGROUND ART

Every year tens of millions of people suffer sudden and unexpected cardiac failure. In order to increase survival rates, defibrillators have been developed, whereby resuscitation of a heart function may be achieved through electrical impulses. Such defibrillators are now widely accessible in public areas and in work places to improve response times from the moment when a cardiac failure occurs to the moment when resuscitation measures are initiated. The defibrillators are increasingly user-friendly to operate, but cardiopulmonary rescue goes beyond the mere use of the defibrillator and there is a need to offer training in cardiopulmonary rescue to civilians in order to fully benefit from the increased accessibility to defibrillators. With proper care from a resuscitation trained civilian until professional help arrives, survival chances of a person suffering cardiac arrest may be increased twofold or even threefold. As the average age of the world's population increases, so does the occurrence of cardiac arrest and the need for cardiac care training civilians.

Currently resuscitation training, such as cardiopulmonary resuscitation (CPR) and emergency cardiac care (ECC) training, is performed on human-size manikins to enable a real-life resembling training situations. Some commercially available manikin models comprise an almost complete body having a head, a torso, arms and legs. Other commercially available models may have a body comprising only a head and a torso. In addition to body type the number of included features can vary significantly between models. In order for training exercises to be more realistic and engaging, the participants may be given info regarding the "subject's state" and/or receive feedback on their actions, either from a teacher supervising the training and/or from the training equipment itself.

A teacher supervising the training may try to replicate a cardiopulmonary rescue situation by utilizing a manikin together with a scenario or program to simulate a subject in need of various types of care. People training CPR and ECC become more engaged and invested in the training when exposed to such cardiopulmonary rescue scenarios in combination with manikins that comprise indicators relating to their health and/or are able to respond to the care administered, such as a manikin reacting with a movement when being defibrillated. The potential complexity and realism of a computer executed cardiac care training scenario or program is usually determined by the number and type of features included in the manikin, features such as simulated breathing, sound generation, detectable pulse or movement actuators.

Some available manikin models comprise advanced integrated subsystems for simulating bodily functions such as movement, pulse, breathing or even bleeding. These manikin models are generally very expensive and are mainly used for professional training performed in a dedicated training environment, e.g., in hospital or university environment. However, cardiac care training of civilians usually requires frequent spatial relocation of the training equipment and puts high demands on the durability and robustness of the training equipment used during such training. The cardiac care training equipment also needs to be practical to transport between training locations, such as workplaces or schools. Thus, manikins currently in use for such training mainly lack features and abilities to give feedback to the person training with them.

There is a need to provide portable equipment for cardiac care training able to carry out cardiac care training scenarios that engage multiple senses. Thus a need for portable auxiliary arrangements usable with existing manikins to add life-sign simulating features also exists.

Patent US9022788 (B2) describes one way to generate a manikin movement using a remotely controlled motion inducer assembly to simulate a defibrillation response when providing training in temporary training facilities. While providing significant improvements to the representation of a realistic scenario, the drawback of the remote control is that this may divert trainer attention from the training scenario to the operation of the motion inducer assembly.

There is a demand for alternative and improved solutions to generate more realistic cardiac care training and/or provide simulated life-signs in portable manikins. Thus there is a need for an arrangement and system adapted for use in temporary training facilities and allowing for a more realistic training environment by simulating life-signs in existing, portable manikins. SUMMARY OF THE INVENTION

It is an object of the invention to improve cardiac care training performed on currently available portable manikins and making the cardiac care training more realistic.

According to a first aspect of the present disclosure, this object has, in accordance with the present disclosure, been achieved by means of a cardiac care training auxiliary arrangement for use with a portable manikin and a defibrillator. During training the auxiliary arrangement is configured to be in direct contact with the manikin when the defibrillator is used on the manikin. The auxiliary arrangement comprises a processor, a communication interface and at least one actuator comprised in a portable housing. The at least one actuator is configured to interface with at least one part of the manikin. The communication interface is arranged to obtain defibrillation information from the defibrillator administering a real or simulated electric shock and to provide said defibrillation information to the processor. The processor is arranged to control at least one of the at least one actuator to move at least one of the at least one part of the manikin upon obtaining the defibrillation information to generate a defibrillation response.

The term defibrillator herein refers to both training defibrillators and real defibrillators. The processor controls automatic movement of at least part of the manikin as the defibrillator administers a real or simulated electrical shock to the manikin. The processor controlling manikin movement may also allow for advanced automatic responses, or changes over time in the observable "medical state" of the manikin receiving cardiac care. The automatic movement response of a manikin upon the defibrillator administering an electrical shock gives sensory feedback to the individuals training cardiac care, e.g., providing tactile feedback as well as visual feedback, thus creating a more realistic and engaging experience. The ability to show a movement response as the manikin receives a defibrillation electric shock allows the individuals training to learn when to perform chest compressions directly after defibrillation instead of waiting for instructions from an automatic defibrillator. The extra delay in performing chest compressions due to waiting for instructions may have significant impact on a patient's health.

According to some embodiments, the portable housing may be arranged in such a way that the manikin is placed upon the housing during use. The housing geometry may resemble a small mattress or an oval mat. The auxiliary arrangement arranged to place a manikin upon may comprise a depression for placing and maintaining a manikin in a desirable position in relation to at least one feature of the auxiliary arrangement, such as an actuator.

According to some embodiments, the auxiliary arrangement may comprise a pair of manikin arms for attachment to a manikin without arms, wherein the pair of arms comprises at least one actuator controlled by the processor and arranged to move at least one arm. The manikin without arms may be a manikin with detachable arms. The auxiliary arrangement comprising a pair of manikin arms may be used to add automatically movable extremities to manikins without arms and/or manikins with removable arms lacking movement features.

According to some embodiments, the processor may further be arranged to control at least one feature simulating a life-sign of the manikin, such as simulating breathing with sound and/or chest movements. One advantage of adding simulated life-signs is that the cardiac care training may become more realistic and engaging. The auxiliary arrangement may comprise at least one sound generation device controlled by the processor, e.g., allowing sounds such as snoring or gasping to be simulated. According to some embodiments, the auxiliary arrangement comprises at least one pulse simulation device controlled by the processor to allow a pulse to be detected at a location on the manikin's body.

According to some embodiments, the simulated manikin movements and/or additional simulated life-signs are coordinated as cardiac care training scenarios controlled by the processor. In such cardiac care training scenarios the manikin may show signs of being in different "medical states" and/or reacting differently to the administered cardiac care, such as a defibrillator administering an electrical shock. The ability to utilize cardiac care training scenarios together with the cardiac care training equipment may improve the training by making training more realistic and engaging. The ability to utilize cardiac care training scenarios may allow a manikin to initially simulate breathing allowing the individuals training to identify situations when chest compressions should not be performed.

According to some embodiments, the auxiliary arrangement comprises a memory storage connected to the processor and arranged to store a computer program comprising program instructions arranged to run on the processor to control at least one feature of the auxiliary arrangement and carry out at least one cardiac care training scenario. The automated control of the cardiac care training using the combination of the processor, memory storage and computer program may be essential to reap the full cardiac care training benefits of adding features for simulating manikin movement and/or life-signs with the auxiliary arrangement.

According to a second aspect of the present disclosure, the above mentioned object is achieved by a cardiac care training system comprising a portable manikin, a defibrillator and the auxiliary arrangement according to the first aspect. During training the auxiliary arrangement is in direct contact with the manikin when the defibrillator is used on the manikin. The auxiliary arrangement is configured to receive defibrillation information from the defibrillator over the communication interface. The manikin may be configured to interface with at least one part of the auxiliary arrangement.

Fig. 1 shows schematically an example portable cardiac care training system 100 comprising an auxiliary arrangement 110a, a portable manikin 120 and a defibrillator 130. During training the auxiliary arrangement 110a is configured to be in direct contact with the manikin 120 and the defibrillator 130 is used on the manikin 120. The auxiliary arrangement 110a comprises a processor, a communication interface and at least one actuator comprised in a housing; the at least one actuator being configured to interface with at least one part of the manikin. The term defibrillator herein refers to both training defibrillators and real defibrillators.

The auxiliary arrangement 110a is arranged to obtain defibrillation information from the defibrillator 130. The defibrillation information may be obtained via a communication cable connecting the defibrillator 130 and the auxiliary arrangement 110a. The defibrillation information may be obtained from a sensor connected to the communication interface arranged to detect a current surge in the defibrillator 130. Upon obtaining defibrillation information relating to a defibrillator 130 administering a real or simulated electric shock the processor controls at least one actuator to move at least one part of the manikin 120 to generate a defibrillation response. The movement of the manikin 120 may be a movement of the head, at least one shoulder and/or at least one extremity. The system may comprise at least one attachable manikin arm and/or leg. The auxiliary arrangement 110a may allow for movement in a manikin 120 without movement features and/or added movement options to a manikin 120 able to move. A multitude of actuators located at different locations may allow for a variation in sensory feedback during cardiac care training.

Fig. 2 schematically shows an example portable cardiac care training auxiliary arrangement 110a for use with a portable manikin 120 and a defibrillator 130, e.g., in the system of Figure 1. The auxiliary arrangement 110a comprises a portable housing 200a, a processor 210a, a communication interface (not shown) and at least one actuator 220a. The communication interface may comprise a connector for a communication cable and/or a Bluetooth communication device. The at least one actuator 220a may be powered by electricity from a battery or an electrical grid and/or compressed gas from a gas tank. At least one actuator may be a pneumatic actuator connected to an electric air compressor comprised in the housing 200a. The communication interface, the processor 210a, and the at least one actuator 220a are positioned at and/or inside the portable housing 200a.

The at least one actuator 220a is configured to interface with at least one part of a manikin 120. The at least one actuator 220a may interface with the at least one part of the manikin 120 via at least one interfacing structure, wherein an interfacing structure may be a cuff arranged to be fastened around a part of the manikin 120. The processor 210a is arranged to control the at least one actuator 220a.

The communication interface is arranged to obtain defibrillation information from a defibrillator 130 and provide said defibrillation information to the processor 210a. The defibrillation information may be obtained via a communication cable connecting the defibrillator 130 and the communication interface. The communication interface may be arranged to detect a defibrillator 130 administering an electric shock by the defibrillator 130, such as a sensor detecting a current surge in an electrical wire connecting the defibrillator 130 and a defibrillation pad in contact with the manikin 120. The processor 210a controlled at least one actuator 220a allows for an automatic manikin 120 movement response directly following a defibrillator 130 administering an electric shock and/or a delayed series of manikin 120 movements. The term electric shock herein refers to both real and simulated defibrillation electric shocks.

The auxiliary arrangement 110a comprises at least one sound generation device 230a. The at least one sound generation device 230a may be controlled by the processor 210a. At least one sound generation device 230a may be a speaker located in the area close to where the head of a manikin 120 is expected to be located during use of the auxiliary arrangement 110a. The sound generation device 230a allows for the sound simulation of a regular breathing or snoring manikin 120 indicating the "subject" is able to breath on their own. The sound generation device 230a allows for the sound simulation of a gasping manikin 120 indicating the "subject" may be going into cardiac arrest. The addition of a sound generation device 230a, independently or in combination with other life-sign simulating features, such as simulated breathing, allows for more realistic and engaging cardiac care training.

The auxiliary arrangement 110a comprises at least one pulse simulation device 250a. The at least one pulse simulation device 250a may be controlled by the processor 210a. The at least one pulse simulation device 250a may comprise a collar arrange at the neck and/or at least one wrist of the manikin 120. The pulse simulation device 250a allows for the "heart rate" of the manikin to be manually detected before and after administering an electric shock with a defibrillator 130. In a training situations with only one defibrillator 130 and multiple manikins 120 with pulse simulation devices 250a the ability to detect pulse may allow the participants to determine which manikin 120 needs the defibrillator.

The auxiliary arrangement may comprise an air pump (not shown) configured to be interfaced with the manikin to simulate breathing. The air pump may be controlled by the processor 210a. The air pump may be connected to a service entrance to the manikin's "lungs" found on a number of manikin models, allowing air pumped into the service entrance to expand the manikin chest in order to simulate breathing. The air pump simulating breathing of the manikin 120 allows for visual and tactile indications of the manikin 120 breathing by itself. A change in manikin 120 breathing pattern may be utilized in training scenarios to indicate a change in medical state.

Fig. 3 schematically shows an embodiment of a cardiac care training auxiliary arrangement 110a for use with a portable manikin 120 and a defibrillator 130, with a manikin 120. The auxiliary arrangement 110a may be the same as the auxiliary arrangement 110a shown in fig. 1 and/or fig. 2.

In a different example (not shown) the auxiliary arrangement may comprise a portable housing configured to be interface on the back of the manikin 120, such as a backpack is worn, wherein the portable housing may be kept on the back of the manikin 120 by at least one shoulder strap, neck strap and/or waist strap configured to go around the shoulder, neck or waist of a manikin 120 respectively. The auxiliary arrangement comprising a portable housing interfaced on the back of the manikin 120 may allow the manikin 120 to be positioned freely during cardiac care training.

During training the auxiliary arrangement 110a is configured to be in direct contact with the manikin 120 and the defibrillator 130 is used on the manikin 120. The processor 210a is arranged to control at least one actuator 220a to move at least one part of the manikin 120 upon obtaining defibrillation information relating to a defibrillator 130 administering a real or simulated electrical shock. The movement of the manikin 120 may be a movement of the head, at least one shoulder and/or at least one extremity. The processor 210a arranged to control at least one actuator 220a may generate at least one manikin 120 movement with a delay after obtaining defibrillator information relating to an electric shock.

Fig. 4 shows schematically an auxiliary arrangement 110b comprising a pair of manikin arms configured to interface with a portable manikin 120. The auxiliary arrangement 110b comprises the pair of arms, a portable housing 200b, a processor 210b, a communication interface (not shown) and at least one actuator 220b. The communication interface and the processor 210b are positioned at and/or inside the portable housing 200b. The at least one actuator 220b is positioned inside at least one of the arms. The processor 210b is arranged to control the at least one actuator 220b and move at least one arm of the pair of manikin arms. Moving the at least one arm may comprise bending the at least one arm at the elbow joint.

During training the auxiliary arrangement 110b is in direct contact with the manikin 120 and the defibrillator 130 is used on the manikin 120. The communication interface is arranged to obtain defibrillation information from a defibrillator 130 and provide said defibrillation information to the processor 210b. The processor 210b is arranged to control the at least one actuator 220b to move at least one arm of the pair of manikin arms upon reception of defibrillation information relating to a defibrillator 130 administering a real or simulated electrical shock to generate a defibrillation response.

The auxiliary arrangement 110b comprising a pair of manikin arms may comprise a back plate connecting the pair of arms. The pair of arms may be connected to the back plate at a dorsal part of the upper arm in an anatomically natural relative orientation, such as the arms orientation in fig. 4, whereby the volume between the upper arms is substantially empty. During use a manikin 120 torso without arms may be placed on top of the back plate, between the pair of manikin arms. The connection between back plate and the pair of arms may be adjustable and allow the distance between the arms to be changed, whereby the upper arms of the pair of manikin arms and the manikin torso may be positioned close together and/or in direct contact. The auxiliary arrangement comprising a pair of manikin arms may be used to add automatically movable extremities to manikins without arms and/or manikins with removable arms lacking movement features.

The auxiliary arrangement 110b comprises at least one sound generation device 230b. The sound generation device 230b may be a speaker located in at least one upper arm of the pair of arms. The pair of manikin arms comprises at least one actuator 240b controlled by the processor 210b arranged to move at least one finger and/or wrist of the pair of manikin arms. The ability to move at last one finger and/or wrist of the pair of manikin arms allows a change in level of consciousness to be simulated and an option for a delayed movement feedback following administered cardiac care. The auxiliary arrangement 110b comprises at least one pulse simulation device 250b. At least one pulse simulation device 250b is located at a wrist of the pair of arms.

The auxiliary arrangement 110b may comprise a memory storage connected to the processor 210b and arranged to store a computer program product arranged to run on the processor 210b to carry out at least one cardiac care training scenario. A cardiac care training scenario governs the observable "state of the manikin" and the manikin's responses to administered cardiac care, such as a defibrillator 130 administering an electric shock, by controlling the at least one movement and/or life-sign simulating feature of the auxiliary arrangement 110a. Turning back to fig. 3, an example of cardiac care training with a manikin 120 and a defibrillator 130 using the present disclosure will now be described. The use of the present disclosure is in no way limited by the described cardiac care training example. In this cardiac care training example the manikin 120 comprises a torso, a head, arms and legs. The manikin 120 has no defibrillation response or life-sign simulating features. The defibrillator 130 is a programmable training defibrillator arranged to provide user instructions and simulate administering electric shocks. The defibrillator 130 is arranged to provide defibrillation information to the auxiliary arrangement 110a via Bluetooth.

The auxiliary arrangement 110a comprises a housing 200a with a mattress shaped geometry comprising manikin placement indicators. The auxiliary arrangement 110a comprises actuators 220a configured to move the arms of the manikin as a defibrillation response, a sound generation device 230a, an actuator 240a configured to interface with and move an ankle of the manikin, an air pump connected to the manikin 120 to simulate breathing, and a pulse simulation device 250a comprising a collar arranged to be around the neck of the manikin. The auxiliary arrangement 110a further comprises a memory storage storing a computer program comprising program instructions arranged to run on the processor 210a to control defibrillation response and simulated life-sign features of the auxiliary arrangement 110a and carry out cardiac care training scenarios. The communication interface of the auxiliary arrangement 110a comprises a touchscreen display configured to allow training scenario selection.

Prior to training the instructor places the auxiliary arrangement 110a on the floor, places the manikin 120 on the housing 200a of the auxiliary arrangement 110a according to the indicators, fastens a cuff connected to the actuator 240a configured to move an ankle around the ankle of the manikin, fastens a neck collar comprising the pulse detection area of the pulse simulation device 250a around the manikin's neck. The defibrillator 130 is connected to the communication interface of the auxiliary arrangement 110a via Bluetooth. The instructor programs the defibrillator 130 to instruct the user to administer a defibrillation electric shock once and then instruct the user to administer cardiopulmonary resuscitation (CPR). The instructor selects a cardiac care training scenario via the communications interface of the auxiliary arrangement 110a. The selected training scenario will be described together with the description of the group undergoing cardiac care training.

The instructor starts the cardiac care training scenario and the group undergoing training is instructed to investigate the manikin 120, trying to determine if the "subject" is breathing. Initially the training scenario activates the air pump and pulse simulation device 250a and plays a gasping sound via the sound generation device 230a, simulating the onset of cardiac arrest. After 1 minute the training scenario turns off the air pump and the pulse simulation device 250a and the sound generation device 230a stops playing sound, simulating cardiac arrest. Upon not being able to detect any simulated life-signs the group undergoing training starts the defibrillator 130 and follows the instructions to attach defibrillator pads to the manikin 120. The defibrillator 130 gives instructions to stay clear of the "subject" followed by a simulated defibrillation electrical shock. Simultaneously as the simulated shock is administered the defibrillator 130 provides defibrillation information to the auxiliary arrangement 110a, whereby the processor 210a controls the actuators 220a configured to move the arms of the manikin 120 to move the manikin's arms. The arms and shoulders of the manikin 120 makes a sudden and noticeable movement as the defibrillator 130 simulates an electrical shock. The defibrillator 130 instructs cardiopulmonary resuscitation be performed on the "subject". The group undergoing training starts CPR on the manikin 120. When 3 minutes has passed since the simulated electrical shock was administered the training scenario actives the pulse simulation device 250a. Shortly thereafter the actuator 240a configured to move the ankle of the manikin 120 moves the ankle substantially towards the torso of the manikin 120, a movement that simulates an increase in level of consciousness. At the same time the sound generation device 230a starts to play breathing sounds, initially at a low volume but increasing to normal volume over time. Shortly after the sound generation device 230a has started the air pump starts to simulate breathing. The group being trained eventually notices the simulated breathing and pulse whereby CPR is halted, the cardiac care training scenario is completed. The instructor may instruct the individuals training to perform CPR directly after the defibrillation movement response during the next cardiac care training scenario.
