The Choke Device - Prototype - Invention Idea

The choke device will be aimed at a small population of individuals that are into these sorts of activities. The device's main goal is to better the methods for individuals that are currently achieving this type of gratification/entertainment by other more risky methods.
Device prototype -
There are individuals out there that are into either auto erotic asphyxiation, or some other form of choking where the goal is to cut oxygen flow to their brain, to achieve different sorts of gratification. They usually do this by tying a belt around their neck or even hanging. Doing it this way is dangerous, as they can "go in too deep" and go limp, which results in the individual's inability to loosen the grip on that's on their neck which can then lead to their accidental death. This device will remove this potential accident by being highly programmable and customized, and also by having preset irremovable security protocols. These safety boundaries will ensure that the individual can go "in pretty deep" into their desired unconsciousness level, without having to worry about going too limp and dying.
Design: It will closely resemble the quality of a sphygmomanometer (device that squeezes to take your blood pressure), that will be designed to not just monitor your vitals but also to accommodate the special squeeze that will target the individuals jugular vain, windpipe, thyroid cartilage (Adam's apple), vagus nerves, and especially the common carotid/carotid body (key parts). Screen will be an easy to understand and operate interface. Will be compact and rechargeable.
- Will also include clear instructions of method of operation
Settings/Limits: The strength of the neck compression (up to 40 pounds of force), the time under tension (which will have a limit of about 15-20 seconds). It will also include custom recommended presets that range from mild to more intense levels of unconsciousness. Lastly it will have programmable cycles as well as preset cycles for continuous rounds of passing out.
