Description

BACKGROUND OF INVENTION

The present invention is a device, system, and method of cardiopulmonary resuscitation hence forth called cpr, which is an important first aid method to help survival of a persons who have suffered a cardiac arrest and is given wide publicity and training, however the survival rate is dismally poor around 2 percent, even though machines to aid the chest compression process in cpr are there in prior art and in market.

However, these machines are not popular due to a serious disadvantage they have in starting the cpr process, as the circulation of blood must be restored to the brain within 5 minutes of blood circulation stoppage to prevent permanent brain damage. The present invention overcomes this disadvantage with inventive steps and a new method of starting cpr along with various other advancements to increase the survival rate of the person who has suffered cardiac arrest hence forth referred to a patient. By stander generally referred to as first responder or as a by passing rescuer, whose help is critical and there is hesitance of men providing resuscitation to women and vice versa, this invention overcomes this hesitancy factor.

FIELD OF TECHNOLOGY

This disclosure relates generally to technical fields of a medical device used in emergency medicine to resuscitate a person who has suffered a heart attack with lack of blood circulation particularly designed to be used by a bystander.

A user manual of Lucas™ and Zoll™ devices is available in public domain and indicates how the prior art device and method works in practice.

Prior art has severe shortcomings by the very method of unpacking the prior art device and proper attachment of the prior art device to the patient and then start the resuscitation process. The time available to start blood circulation is less than 5 minutes, there is no time left for normal human thinking process after the initial shock and surprise in the sudden event of a heart attack. Bystander help is very critical, there is no time to educate or give him expertly instructions. Due to these difficulties in prior art the success rate of cardiopulmonary resuscitation is dismally low at 2 percent. A manicure-based training of general public and even medical professionals are not widely popular and has its own difficulty to remember steps and sequence, position needed for the rescuer and the correct amount of pressure to be applied. Prior art devices need correct latching to provide counter force for the compressive element and also for correct positioning of compression pad. This is where time is lost for the first-time user, figuring out how to use and what to do wastes valuable time, time to overcome shock and surprise, time to unpack the device, figuring out where the buttons to start is present, wastes even more time. It may be easy to latch but will take time to figure out how to latch for a new user. Inserting the prior art belt drive-based device under the patient, wastes critical time and needs another person's help.

The present invention and method addresses all the above problems with an automated mechanical pressure compression source with sitting arrangement being a well-supported and prominent seat to provide a counterweight for compression strokes. A latching member being one of a pad, a plate and a belt with coupler henceforth called as back pad, that is inserted later once the circulation is started, with the latching member being suspended from the arm or leg of the device and further a patient carrying board is also inserted much latter, below the patient, to enable transport of the patient.

SCOPE OF INVENTION

A death due to heart attack as seen in case of prominent persons like A P J Kalam could have been prevented if a timely action as enabled by the present system was present and seeing a politician collapse and fall down is not an excuse specially when intelligent ways and systems as that taught by the present invention can be deployed in large numbers. The cultural and moral problem of providing cardiopulmonary resuscitation to a woman, a lady who is a stranger, in a public place is a real problem. similarly women will hesitate to provide resuscitation to a man and by the time a decision by overcoming inhibition happens, it's too late to save a life. This invention perfectly solves this ethical dilemma enabling anyone to help anyone else. The lost lives so far is an evidence for non-obviousness of the present invention.

Emergency handling in hospital can be greatly improved so doctors can come more relaxed and need not run, this will revolutionize emergency medicine. A very clearly understandable, unambiguous two step method of sitting on the device placed over the patient, no confusion, no decision steps, no mental thinking on what to do. Even keeping a skilled and trained person being available all 24 hours for a very important person like presidents and ministers etc is a challenge so the need for whoever available person to provide help in case of a cardiac event.

Single person can start and gain time, getting a second persons to help wastes time in telling him or her what to do, communication wastes time and leads to decision errors.

The device, systems, and methods disclosed herein may be implemented in any means for achieving various aspects, and may be executed in a form of a machine-readable medium embodying a set of instructions that, when executed by a machine, cause the machine to perform any of the operations disclosed herein. Other features will be apparent from the accompanying drawings and from the detailed description that follows.

Further additional drawings are provided to clarify about what the counter force to the compression force is, which is a counter force to the reactive force arising in opposite direction to the compression force, with the said reactive force arising at the same time as when the compression force is being applied. This should not be confused with the compression pad and its rods return force provided by spring shown as 506 in FIG. 5 where I have called the said spring 506 as compression pad return spring.

I have tried to explain the counter force to resuscitation force with schematic diagrams for the sake of simplicity with FIG. 32 A showing a schematic diagram of the cpr device being placed on a ground 3200, with the cpr device being 3201, having enclosure box 3202 containing compression drive, a compression pad 3203, front part of frame 3204, connected to back part of frame 3205 having back pad or plate with said connection being by latch 3206, and into this frame a pumpkin 3207 is placed which is acted upon by compression pad 3203.

The compression action by compression pad on the pumpkin is shown in FIG. 3 B with arrow 3209 showing direction of compressive force, arrow 3210 shows direction of the reaction force which is opposite to the compression force and occurring at the same time as the compression force. FIG. 3B shows the compression force acting on the pumpkin resulting in the pumpkin getting compressed; notice the latch 3206 is fixed. Now disconnect the latch 3206 and thereby disconnect front part of frame 3204 from back part of frame 3205 and start the machine, what happens is shown in FIG. 3C The reactive force 3210 moves the front part of the frame, away from compressor pad and the pumpkin is not compressed, since a force to restrain the upper frame from moving is missing when latching is not done. Avoiding latching and fixing is essential to save time to start cpr assuming an untrained, low intelligence bystander has to connect the cpr machine and has to do it with in 3 minutes when the brain damage begins to start from hypoxia, 3 minutes as told to me by a cpr expert. So, when no latching is done the reactive force shown by arrow 3210 has to countered with an oppositely directed force, the said force being external to the device. This counter force is what has been called all along this patent document, as counter force to resuscitation force and this external force is provided by the weight of a rescuing person as described from the beginning to the end of this document.

FIG. 33 A shows the patient 3301 surrounded by the cpr device 3302 with upperpart of frame 3303 having enclosure box which has drive mechanism, and latch disconnected shown as 3304. FIG. 33B shows the front part of frame moving upwards as indicated by arrow 3305 under the influence of reactive force to the compression force while FIG. 33 B shows the front part of frame moving downwards under the force 3306 from weight of device. FIG. 34 shows the patient 3401 with the novel cpr device 3402 with seat 3403 and rescuer 3404 and arrows 3405 showing compression force, 3406 the reactive force and 3407 the counter force to the reaction force of compression force byway of the rescuers body weight.
