Abstract
A tourniquet with audio instructions comprising: a tourniquet with a belt, clip, securing strap, and instruction module; a release switch can be activated when the tourniquet is put in use so that audio instructions are provided to the user for using the tourniquet. The invention can include the instruction module being carried by a holster that also carries the tourniquet. The instruction module can be activated when the tourniquet is removed from the holster, unfolded or manually actuated. The tourniquet can be retained in a holster and the instruction module is activated when the tourniquet is removed from the holster.
Core Innovation
The invention provides a tourniquet with audio instructions comprising a belt, buckle, securing strap, clip, and an instruction module. The instruction module includes a control module with a control medium and an audio medium configured to store and broadcast user instructions through a speaker. The module can be activated by a manual or release switch, providing step-by-step guidance for proper tourniquet application when the device is used.
It addresses the problem that, while tourniquets such as the Combat Application Tourniquet (C-A-T) are effective, improper application due to lack of knowledge—particularly by the general public or in stressful emergency environments—can lead to complications such as tissue damage or increased bleeding. Existing medical audio instruction devices are not well suited for integration with field tourniquets or for emergency trauma use.
This invention further enables the instruction module to be attached to the tourniquet or a holster, with activation possible through removal from the holster, unfolding the belt, or manual actuation. Additional features include sensors to detect the perimeter and compression force applied by the belt, as well as a pressure indicator to inform users if the applied pressure falls below predetermined levels based on the limb type, thereby promoting proper and effective tourniquet use.
Claims Coverage
The patent contains several independent claims that establish inventive features related to tourniquets equipped with integrated audio instructions modules and pressure sensing capabilities.
Tourniquet with integrated audio instruction module and automated activation
A tourniquet comprising: - A belt and buckle assembly optionally carried by a holster. - An instruction module attached or carried by the belt, including a control module. - A control medium and audio medium within the control module storing user instructions. - Audio instructions broadcasted through a speaker in the instruction module. Activation can occur via a manual or release switch when the tourniquet is put in use, removed from a holster, unfolded, or manually actuated.
Release switch and removable tab for automatic instruction activation
A release switch in the control module, actuated by removal of a physical tab connected toward the distal end of the belt, triggers the broadcast of audio instructions automatically when the belt is unfolded or prepared for use.
Pressure and perimeter detection for user feedback
The control module includes: - A set of electrical contacts carried by the belt to detect the perimeter when applied to a limb. - A gauge (including a strain gauge) for determining compression force. - A pressure indicator activated when compression force falls below predetermined, perimeter-dependent thresholds, providing user feedback for proper application.
In summary, the patent claims coverage for tourniquets that provide integrated, automated audio instruction, user-actuated or automatic activation features, and user feedback on application correctness using perimeter and pressure sensing.
Stated Advantages
Provides audio instructions directly to the user to promote proper application of the tourniquet.
Can be activated in the normal operation of the tourniquet, ensuring instructions are delivered at the correct time.
Provides feedback concerning the pressure applied by the tourniquet, helping users apply effective and safe levels of compression.
Documented Applications
For use on extremity wounds to control life-threatening vascular hemorrhaging in battlefield, civilian emergency care, police, fire departments, and public places.
Deployment in public locations such as airports, movie theaters, schools, malls, and the like for use by the general public or non-expert users.
For emergency treatment of victims at the incident location or in subsequent healthcare settings.
Use in situations such as penetrating trauma from firearms and stabbings, terrorist attacks, wilderness injuries, and industrial or farm accidents.
