[0014] Beneficial Effects
[0015] The present invention provides an open chest trauma treatment device, which has the following beneficial effects compared with the prior art:
[0016] 1. When in use, the medical staff presses the ring sleeve into the wound on the patient's chest and places the thin tube in the ring sleeve. At this time, the medical staff holds the pressure ring, aligns the screw with the axis of the pressure tube, and presses down the pressure ring, so that the connector begins to be sleeved on the screw, and begins to push the pressure ring continuously. At this time, since the screw does not have the characteristic of self-locking effect, it can convert linear motion into rotation. At this time, the connector begins to rotate with the cooperation of the screw threadedly connected to it, and drives the gear A fixedly connected to it to start rotating, so that the gear A starts to push the rack A meshing with it, and the rack A starts to move along its The connection with the pressing cylinder makes linear movement, and pushes the connecting frame fixedly connected to it to slide synchronously. At this time, the reels connected to the two connecting frames begin to move synchronously towards each other, and cooperate with each other to close to the thin tube. At the same time, the two gears begin to mesh and connect. At this time, the user can start, so as to drive the shaft fixedly connected to its output shaft to rotate synchronously. At this time, the gear fixedly connected to the shaft begins to rotate, and the two meshing gears rotate synchronously. At this time, the two reels begin to rotate synchronously, and cooperate with each other to start pushing the thin tube, so that the airbag passes through the ring sleeve to reach the bleeding point in the chest cavity;
[0017] 2. The user starts the motor A, so that the motor A drives the screw rod fixedly connected to its output shaft to rotate synchronously, and drives the slide cylinder threadedly connected thereon to start sliding along the connection between it and the ring sleeve. At this time, the slide cylinder starts to push the push rod B hinged thereto, so that the push rod B starts to push the push plate hinged thereto, and the slider slidingly connected to the other end of the push plate starts to move linearly along the connection between it and the push plate, and starts to drive the push rod A hinged thereon to move synchronously, so that the push plate starts to move linearly at a uniform speed under the cooperation of the push rods B and A until it contacts the airbag, and presses the airbag tightly against the capillary with the cooperation of multiple push plates. At the same time, the push plate is provided with a soft rubber strip, which can effectively make it close to the airbag. At this time, the airbag in the ring sleeve is inflated. The device will not expand downward, so that the device can be used for chest walls of different thicknesses and bleeding points of different depths. Then, the user starts to inflate the airbag through the trachea, so that the part of the airbag under the cuff begins to expand, and the cuff is pulled upward, so that the part of the airbag in the chest cavity can be in close contact with the chest wall. At the same time, the part of the airbag under the cuff expands and applies pressure to the bleeding site, so as to prevent the wound from continuing to bleed. Then, the part of the airbag under the cuff stops expanding, and the part of the airbag on the upper side of the cuff starts to expand. At the same time, the part of the airbag on the cuff expands so that it can be in close contact with the patient's body surface, so as to seal the wound and prevent air from entering the chest wound to form pneumothorax. At the same time, the airbag can be tightened to cooperate with the part of the airbag in the body, and the airbag as a whole can be fixed at the wound on the patient's chest.
[0018] 3. When the user presses the pressure ring, after the pressure ring slides a distance, gear B begins to be driven to slide onto rack B. At this time, the pressure ring continues to slide, so that gear B can begin to roll on it with the cooperation of rack B meshing with it, thereby starting to drive the left-handed screw fixedly connected to it to start rotating. At this time, the left-handed screw begins to drive the right-handed screw fixedly connected to it to rotate synchronously, and makes the sliding cylinder threaded on the left-handed screw and the right-handed screw begin to move linearly along the connection between them and the right-handed screw, and drives the splint fixedly connected thereto to move synchronously. At this time, the two splints begin to move towards each other, and when the pressure ring is close to the airbag, the two splints begin to cooperate with each other to approach the capillary, thereby guiding the capillary during the pushing process to prevent the capillary and the airbag from deviating.
