Abstract: The present invention directs to a safety control system for portable weapons, including, but not limited to, crossbows and firearms, such as guns, rifles and alike, using various sensors to ensure safe target, environment, location, and situation for operating portable weapons. The safety control system unlocks a firing sequence of the portable weapons only when it is safe to operate.

Abstract: A safety control system (200a, 200b, 200c, 200d, 200e) for portable weapons, including, but not limited to, crossbows and firearms, such as guns, rifles and alike, uses various sensors to ensure safe target, environment, location, and situation for operating portable weapons. The safety control system (200a, 200b, 200c, 200d, 200e) unlocks a firing sequence of the portable weapons only when it is safe to operate.

Abstract: Safety lock mechanisms (C1-C28) for a portable weapon is disclosed. Such a mechanism includes an actuator (M3), and locking means operable from an unlocked state to a locked state by the actuator (M3) for blocking a firing sequence of said portable weapon. The blocking of the firing sequence is carried out at a trigger, a trigger lever, a hammer, or a firing pin of the portable weapon. The actuator (M3) may be a push-pull solenoid or servo motor.

Abstract: A negative pressure sealing drainage system for surgical treatment of deep cavity wound includes: a columnar porous foam drainage piece, a wave-form sealing cover which is extendable and retractable, a medical film, a drainage tube, a fluid storage container, and a negative pressure source. The columnar porous foam drainage piece is a hydrophilic foam, and is enclosed within the wave-form sealing cover. One end of the drainage tube is inserted into an upper portion of the columnar porous foam drainage piece. A flap provided along a circumference of the bottom-most end of the wave-form sealing cover adheres to skin surrounding a deep cavity wound. An upper end of the wave-form sealing cover is provided with a tube-shaped connection opening sealingly connected to the drainage tube communicating with a connection tube via a straight-tube fitting and inserted into the fluid storage container. The fluid storage container communicates with the negative pressure source via a connection tube.

Abstract: A vacuum sealing drainage device for a bleeding wound tissue, includes a multi-hole foam cushion (1) contacted with the bleeding wound tissue, a drainage pipe (2) with a side hole, a sealing film (3), a connector (4), a duct (17), a drainage container (5), and a vacuum source (6). The device further includes a glue film (7) and an leading-out pipe (8). The glue film (7) is disposed above the multi-hole foam cushion (1). An opening of the side hole of the drainage pipe (2) is contacted with the multi-hole foam cushion (1). The leading-out pipe (8) is connected to the drainage pipe (2), and is disposed above the glue film (7). The sealing film (3) is sealed on the glue film (7). The leading-out pipe (8) is received in the drainage container (5) via the duct (17), and the drainage container (5) is connected to the vacuum source (6) via the duct (17). The device increases time of maintaining elasticity and a humid environment for the multi-hole foam cushion, which is helpful for wound healing.

Abstract: An adhesive film including an upper surface including a developing reference axis. The adhesive film is simple in structure, accurate in positioning, and convenient for practice.
