Hundreds of new patents, most being only for syringes, not generally adaptable to clinical needs, all more expensive than unsafe devices.
The main ideas on offer are "Needle Capturing Systems" where the syringe must be empty before it can be made safe. One has a spring which makes it unsatisfactory for injecting into a vein.
The Breakthrough
For 40 years doctors have inserted thin plastic tubes into the body using solid needles. We found to our great surprise, that when such a plastic tube extended a couple of millimetres beyond the tip of a needle the needle could not be pushed into skin. It was effectively blunted. We immediately saw that this technique could be easily arranged to make all injection devices safe - NOT JUST SYRINGES. The Needlesleeve principle can be applied to all injection devices. Interested medical manufacturers are invited to discuss licensing of these devices:
An automatically safe needle
An automatically safe blood collector "vacuum sampler"
Vacuum Sampler
Automatically Safe Vacuum Sampler
Suggested for production because:
Used in all clinics around the world in increasing numbers to take blood for pathology testing.
Easy to register and introduce into clinical use because not used for injections.
Market size about 4 billion units per year costing about $3 billion.
No other inventors or any other company has previously succeeded in making a safe and efficient device to meet this clinical need.
Automatically Safe Needle
Chosen because:
No other inventors or any other company has previously succeeded in making a safe and efficient device to meet this clinical need. (A partial exception is the "Clip-On" retractable needle which I invented 15 years ago.)
