This invention proposes an aid for prevention of wound dehiscence, which is highly effective in preventing the dehiscence of an incised wound inflicted on a body by cutting, and is easy to use and manipulate; in particular this aid for preventing an incised wound caused to a part of a body by incision from splitting open by covering the wound and wound-surrounding tissues, is made up of a dehiscence preventive member adapted to cover up the wound and the wound-surrounding tissues, a plurality of a holding member adapted to hold the dehiscence preventive member closely upon the wound and the wound-surrounding tissues, and a contraction preventive member having a capacity of keeping the dehiscence preventive member suitably expanded in a dehiscence direction and of preventing the expanded dehiscence preventive member from contracting; and said dehiscence preventive aid is unique in that the aid is adapted to effect such that a contraction distance of the dehiscence preventive member in the dehiscence direction which is determined in response to the application of the dehiscence preventive member is equal to or greater than a contraction distance of the holding member in the dehiscence direction which is determined in response to the application of the holding member, and in that the dehiscence preventive member is adapted to be closely applied to the wound and the wound-surrounding tissues after being expanded in the dehiscence direction in a manner such that the contraction distance of the dehiscence preventive member in the dehiscence direction which is determined in response to the application of the dehiscence preventive member is equal to or greater than the contraction distance of the dehiscence preventive member in a direction normal to the dehiscence direction which is determined in response to the application of the dehiscence preventive member, and in that the contraction preventive member is removed after the dehiscence preventive member is applied by being fixed with the holding member.

The invention relates to the technical field of out-of-plane puncture, and discloses an ultrasound-guided out-of-plane puncture adapter which is mounted on an ultrasonic probe. The adapter comprises a first fixing device mounted on the ultrasonic probe and a second fixing device used for fixing a puncture needle and connected with the first fixing device, wherein the second fixing device corresponds to a center short shaft of the ultrasonic probe and comprises two opposite right-angle fan-shaped clamping pieces and a locking device used for locking the former two; a movable sleeve is arranged between the two right-angle fan-shaped clamping pieces; the puncture needle is arranged in the movable sleeve; and one end of the movable sleeve is arranged at the right-angled vertices of the right-angle fan-shaped clamping pieces, and the other end thereof moves along the circular arcs of the right-angle fan-shaped clamping pieces. The invention further discloses an ultrasound-guided out-of-plane puncture device and a puncture method thereof. According to the invention, the problem that the corresponding puncture adapter is not available in an ultrasound-guided out-of-plane puncture technology is solved, and the application of the ultrasound-guided out-of-plane puncture technology in the clinical medical field is greatly promoted.

The invention relates to a rack for conveniently adjusting parts during assembly. The rack comprises hooks, hangers and a rack body. The hooks are mounted on the hangers and used for hanging workpieces, the hangers are detachably mounted on the rack body, and the rack body is used for supporting the hangers. The rack is stable in structure and reasonable in layout, the hangers can be detachably connected with the rack body, the hangers can be conveniently dismounted and mounted automatically through a machine, automation can be conveniently achieved, and the machining efficiency can be effectively improved.

The invention discloses a blast furnace drying method, which belongs to the field of blast furnace metallurgy. The invention comprises the following steps: 1. installing thermocouples at the center of the blast furnace bottom, above the tuyere, and on both sides of the front end of the tuyere; Cooling water channel, keep part open; 3. Start the hot blast furnace system to vent hot air into the blast furnace to bake the furnace, and keep the open cooling water channel in the furnace bottom cooling pipe and cooling wall to circulate water; 4. When the thermocouple detects the blast furnace bosh When the cooling wall temperature reaches above 90°C, open all cooling water channels to participate in circulating water supply until the end of the oven. The invention overcomes the disadvantages of poor blast furnace baking effect and affecting the life of the blast furnace in the prior art, can increase the actual baking temperature of the filler, improve the strength of the monolithic refractory material and the overall baking effect of the blast furnace, and promote the longevity of the blast furnace.
