5results about How to "Effective closure" patented technology

This utility model relates to the field of minimally invasive postoperative wound dressing technology, specifically a minimally invasive postoperative wound dressing with wound closure function. It includes an adhesive layer, release paper installed on both sides of the bottom of the adhesive layer, low-sensitivity adhesive tape evenly installed on both sides of the top of the adhesive layer, and a sterilization layer embedded in the middle of the adhesive layer. The improved minimally invasive postoperative wound dressing adds a first elastic band and a second elastic band. When the wound dressing is applied to the wound surface, the first and second elastic bands can be pulled to traction the sides of the adhesive layer, thereby effectively closing the wound, reducing the risk of wound dehiscence, and promoting rapid wound healing. An absorbent layer made of highly absorbent resin is also added, allowing the absorbent layer to quickly absorb tissue fluid exudated from the wound during the healing process, helping to reduce the risk of wound infection and thus promoting wound healing.

The utility model relates to a dispensing tool for carton forming processing, which comprises a main frame body, a rolling dispensing assembly is rotatably mounted on the main frame body, and the rolling dispensing assembly is connected with a pressurized liquid supply assembly mounted on the main frame body through a liquid supply supporting pipe. The rolling dispensing assembly comprises a rotating disc, supporting rib rods, a mounting ring plate and a telescopic dispensing mechanism, the rotating disc is rotatably connected with the main frame body, and the rotating disc is coaxially connected with the mounting ring plate through the supporting rib rods which are annularly arranged at intervals; and a plurality of telescopic dispensing mechanisms which radially coincide with the mounting ring plate are inserted into the mounting ring plate in a rotational symmetry manner. According to the utility model, the dispensing spacing distance can be changed according to requirements, so that the dispensing quality and the dispensing efficiency are improved, and meanwhile, the pressure-contact glue discharging can be realized, so that the overflow and splashing of glue liquid are reduced.

The application discloses a contact assembly and nanocrystalline relay and relates to the technical field of relays; the application comprises an insulating frame, two static sheets are arranged on the insulating frame, and static contacts are arranged on the static sheets; a movable plate is slidably arranged on the insulating frame, a dynamic sheet is arranged on the movable plate, two dynamic contacts are arranged on the dynamic sheet; a differential mechanism comprises a frame fixed to the insulating frame, first guide rods and second guide rods are rotatably penetrated into opposite inner walls of the frame; the force generated by an electromagnetic component does not directly act on the dynamic sheet, the differential mechanism is arranged, two-stage speed increase is realized by the differential mechanism, the moving stroke of the dynamic sheet is greater than the moving stroke of the first rack driven by the electromagnetic component, and the moving speed of the dynamic sheet is faster than the moving speed of the first rack driven by the electromagnetic component during the closing or breaking process; the separation speed and the breaking distance are increased, the contact breaking force is sufficient, the generation of electric arc is reduced, and therefore the practicability is improved.

The invention discloses a boron neutron capture therapy patient collision protection device which is installed on a collimator and connected with a treatment room safety interlocking system, the protection device comprises a base, a floating type orifice shell and a pressing ring, the floating type orifice shell comprises a multi-directional floating assembly, the multi-directional floating assembly comprises an axial floating assembly and a radial floating assembly, and the axial floating assembly and the radial floating assembly are arranged on the base. A floating trigger loop is arranged between the floating type orifice shell and the pressing ring; and a floating contact and a contact point which are used for realizing the on-off of the floating trigger loop are arranged in the floating trigger loop. The emergency stop protection can be achieved when the treatment bed moves in the front-back direction, the up-down direction, the left-right direction and the like, and all-directional collision protection and overshoot buffering in the maximum range are achieved. When collision occurs, the multidirectional floating assembly generates floating deformation, the floating trigger loop is disconnected, the treatment room interlocking system sends an emergency stop signal to the treatment bed, the treatment bed enters an emergency stop state, the design of collision-disconnection-overshoot buffering is achieved, the safety performance is high, and the protection effect is good.

The application discloses a relay control circuit, a relay control method and an electric vehicle, and relates to the technical field of electric vehicles. The relay control circuit is used for controlling a relay, the relay is arranged on a high-voltage loop of a power battery pack, the relay control circuit comprises a plurality of controllers, the controllers are controllers in any management system of the vehicle, the controllers have power output ends, the power output ends are connected with each other to form a ring-shaped loop, an input end of a coil in the relay is connected with the ring-shaped loop, and an output end of the coil is grounded. According to the application, the plurality of controllers are used for jointly controlling the relay, even if the voltage output by part of the controllers cannot reach the driving requirement of the relay, the remaining controllers with normal output can ensure the normal driving of the relay, the contact of the relay can be effectively closed, the risk of arc drawing is reduced, the sticking of the relay is avoided, and the safety of the vehicle is ensured.
