Personal protection device

A pocket-sized self-defense spray device is capable of dispensing a chemical irritant to cause temporary breathing difficulty and a burning sensation in the eyes of the target without any permanent damage. The device comprises a casing, a nozzle, and a multi-position trigger. The trigger is slidably mounted in the casing to be moveable from a safe position to an active position. The casing may contain a battery-powered light that is switched on to illuminate the target when the trigger is in the active position. The trigger button in the second position may then be depressed into an engaged position that causes chemical irritant to be discharged from a removable canister with a poppet valve into a nozzle chamber, and out the nozzle exit at a target. The casing includes an ergonomic finger grip that serves to prevent inadvertent discharge at the user, and ease of aiming at the target.

Formula, a system and a method for treating urushiol induced contact dermatitis

A formula, a system and a method is provided for treating urushiol induced contact dermatitis, chemical irritants and / or microbiological irritants on an affected area of skin of a user. The formula and / or the system is applied to an area of the skin of the user affected with urushiol, the chemical irritants and / or the microbiological irritants. The formula and / or the system have a cleansing agent, one or more surfactants and / or one or more abrasive agents for treating the urushiol induced contact dermatitis, the chemical irritants and / or the microbiological irritants. One or more abrasive agents separates the urushiol, the chemical irritants and / or the microbiological irritants from the skin of the user at the affected area. The cleansing agent bonds to the urushiol, the chemical irritants and / or the microbiological irritants at the affected area and withdraws the urushiol, the chemical irritants and / or the microbiological irritants from the tissue under the affected area of the skin of the user. The formula, the system, the urushiol, the chemical irritants and / or the microbiological irritants may be rinsed away from and / or may be removed from the affected area of the skin of the user. As a result, the urushiol induced contact dermatitis, the chemical irritants and / or the microbiological irritants is treated and / or is terminated by the formula, the system, the cleansing agent and / or one or more surfactants.

Diagnosis and treatment of inflammation and hyperactive immune conditions

Ecto-NTPDase function on Langerhans cells is demonstrated to counteract the nucleotide inflammatory response caused by certain types of chemical irritants. The present invention takes advantage of this observation by, first, providing methods for screening of chemicals for irritant potential based on their ability to induce nucleotide release from keratinocytes. Second, methods are provided for the prevention and treatment of inflammation using NTPDase protein or gene therapy. And third, there also are provided methods for screening candidate compounds for NTPDase modulatory activity, thereby identifying possible pro- and anti-inflammatory agents. Additionally, the role of NTPDases and P2 receptors in hyperactive immune conditions such as autoimmune diseases and allergic reactions such as allergic contact dermatitis has been demonstrated. Therefore, the invention also provides methods for the prevention and treatment of hyperactive immune conditions by using NTPDase inhibitors and / or P2 receptor inhibitors. Further provided are methods for screening candidate compounds for modulatory activity of NTPDase-mediated immune conditions, thereby identifying other possible immunotherapeutic agents.

Personal protection system

A personal protection system has a shaft that can be secured into a pair of end bases that mount to a surface of the surroundings of the user. The shaft and bases are configured to appear as a natural part of the surroundings, such as a support bar or rail, when the shaft is stored. The shaft can be removed, and has an end portion adapted to provide a weapon for self defense. For example, the end portion can employ a piercing point, a syringe and needle for injecting a bio-toxin, a canister for spraying a chemical irritant, an appliance for generating an electrical shock, or combinations of these elements. Preferably, the shaft is secured into the bases so as to be usable for support. It is further preferred for the bases to be configured to disguise the fact that the shaft can be removed.

Housing for chemical irritant dispenser

InactiveUS20060175347A1Conveniently firedPrecise aimingDollsLarge containersEngineeringActuator
A housing can be mounted to a pistol or other weapon and conveniently fired therefrom and can be used as a discrete weapon itself. A cap has a central aperture which secures the nozzle and / or valve stem of a canister of chemical irritant from movement and is secured to the proximal end of a hollow tube. A feature of the new invention is a slot access running along the length of the tube for some distance from its distal end. The tube may be either open or closed at its distal end. Toward the distal end of the tube, an interior ridge or stop cooperates with the cap aperture to secure the canister of irritant. When a canister is installed in the housing, the operator can release an irritant spray axially from the canister by pressing a digit against the side of the canister's storage cylinder and, thereby, displace its longitudinal axis along an arc. The housing need have no other mechanisms, except the housing and canister. This method also allows for convenient triggering of a spray from a canister within the housing when the housing is secured under or adjacent to the barrel of a handgun. In some embodiments an actuator compresses against a spring-loaded pusher to contact the side of the storage cylinder and move the longitudinal axis of the storage cylinder to release a spray.

Chemical irritant dispenser

According to the present invention, a dispenser for dispensing a substance from a pressurized canister having a nozzle selectively operable to control release of the substance is provided. The dispenser includes an elongate housing for a pressurized canister, where the housing includes a proximal end, a distal end, and a sidewall. The distal end of the housing has an aperture formed therein, and the sidewall has an opening formed therein. An actuator, which is movable at least axially forward toward the distal end and axially backward toward the proximate end, extends within the elongate housing through the opening and cooperates with a nozzle of the pressurized canister. To operate the dispenser, the actuator is moved to an axially forward firing position in which the actuator causes the nozzle to operate, thereby releasing the substance from the pressurized canister through the aperture in a substantially axial direction.
