Patents by Inventor Elroy T. Cantrell

Elroy T. Cantrell has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10702138
    Abstract: A dual blade laryngoscope having a folding handle and a manually installable lighting cartridge. The laryngoscope includes two spaced apart parallel blades and a wall spanning both. A slot is formed at one end of the parallel blades for receiving the lighting cartridge. A translucent or transparent lens covers a visualization channel defined between the parallel blades. The folding handle includes an axle to enable pivoting between a deployed position and a stowed position, and a projection which activates the lighting cartridge. The lighting cartridge and the transparent lens are removable. Each of the parallel blades has a curved portion at forward ends thereof to facilitate managing soft tissue and directional control of an endotracheal tube during insertion in a patient. A tooth guard pad of compliant rubber-like material may be permanently affixed to the underside of lower blade.

  • Patent number: 7500948
    Abstract: A dual bladed laryngoscope for quickly and easily intubating a patient. The invention has two blades pivotally hinged on one side while the opposing side is open allowing the laryngoscope to be easily removed after intubating a patient. The proximal end of the upper blade has a grip portion which can be moved closer to or farther away from the handle attached to the proximal end of the lower blade to open or close the distal ends of the lower and upper blades. The lower blade of the invention has a distal end adapted as an esophageal obturator for obstructing the esophagus. An arytenoid bumper to prevent the laryngoscope from penetrating too far into the esophagus is preferably secured to the distal end of the lower blade. The arytenoid bumper may have a ramp or wedge shape adapted to deflect an intubation tube through a patient's larynx and into the trachea.

  • Patent number: 7223103
    Abstract: An inexpensive take-home training aid for practicing human cardiopulmonary resuscitation (CPR) is contained in a non-humanoid shaped housing. When placed in a prominent location in the home, such as a child's room, the CPR training aid reminds users of the CPR sills they have learned and encourages them to practice with the training aid. The internal mechanism consists of a simulated airway, a compression mechanism, a compression feedback mechanism, a metronome, a breast plate and back plate with simulated anatomical landmarks, and/or an external landmark for identifying the proper location for placing a hand, hands, or fingers on the chest. Voice prompts on the steps of CPR and/or actual CPR performance may also be included. The chest plate and back plate are connected by one or more telescoping posts and a resistance device is between the two plates to simulate the resistance of a human chest to compression.

  • Publication number: 20040116840
    Abstract: The Chest-positioner/pad Cardio Pulmonary Resuscitation System (CCPRS) provides improved resuscitation during one-person or two-person CPR. The simple, compact, portable and cost-effective system provides for manual, mechanical or electrical driven external chest compressions via a socket connection to a chest-positioner/pad unit. The chest-positioner/pad unit provides greater control of compression positioning providing adequate and reproducible chest compressions while preventing rib fractures and damage to vital internal organs. A module gives providers feedback to enable a provider to apply an appropriate compressive force in an appropriate direction, recurringly under emergency conditions. The present invention also provides improved blood circulation, oxygenation and gas exchange by expanding the chest past its normal relaxation point during diastole.
