The working principle is that firstly, when hemostasis needs to be pressed, the driving motor 7 is started to drive the rotary table 12 to rotate, when the rotary table 12 rotates, the mounting column 13 on the left side wall of the rotary table 12 can drive the sliding frame 14 to slide back and forth on the right side wall of the mounting frame 2, when the sliding frame 14 slides backwards, the pawl 17 on the upper portion of the sliding frame 14 can be clamped with the ratchet 15 to push the ratchet 15 to drive the worm 11 to rotate, when the sliding frame 14 moves forwards, the pawl 17 can be extruded by the ratchet 15 to rotate and drive the second torsion spring 18 on the outer wall of the bearing 16 to contract, so that the ratchet 15 cannot be pushed to rotate reversely, the effect of intermittently pushing the ratchet 15 and the worm 11 to rotate can be achieved, the worm 11 can be meshed with the worm wheel 10 to drive the first bidirectional spiral grooved rod 3 to rotate, when the first bidirectional spiral grooved rod 3 rotates, the groove wall of the first sliding shaft 4 can extrude the sliding sleeve 5 and the compression plate 6 to descend, and the compression plate 6 can be lowered intermittently and slowly by matching with the intermittent rotation of the worm 11, the phenomenon that pain of a patient caused by direct descent of the compression plate 6 can be prevented, and the phenomenon caused by the subsequent hemostasis does not need to be convenient for observing the wound lifting of a medical care worker to stop the wound according to a certain time of the wound, and the wound lifting of the wound 6 to stop bleeding wound;
please refer to fig. 1 to 7 for the motion process of the above structure.
One end of an isolation cotton roll 21 is pulled to be adhered to the outer wall of a fixed column 20 in an initial state, then a sliding frame 14 drives a multi-section telescopic rod 23 to move back and forth through a long plate 22 when moving back and forth, the multi-section telescopic rod 23 slides back and forth, a second sliding shaft 25 at the lower part of the multi-section telescopic rod can slide on the groove wall of a second bidirectional spiral groove rod 24 and extrude the second bidirectional spiral groove rod 24 to drive the fixed column 20 to rotate towards one direction all the time, the isolation cotton roll 21 can be rolled up when a compression plate 6 rises or falls, the isolation cotton roll 21 at the lower part of the compression plate 6 can be kept clean when next patient is pressed to prevent bleeding, the phenomenon that the compression plate 6 directly contacts with the wound of the patient and is stained with sweat, blood or bacteria is avoided, a new isolation cotton roll 21 can be timely and automatically replaced, and the phenomenon that different patients use the same compression bleeding prevention device is effectively prevented from causing cross infection of the wound;
the above structure movement process refers to fig. 2, fig. 6 and fig. 8.
When the compression plate 6 descends, the sliding plate 26 is stretched by the connecting rod 33 to move downwards, so that the chute 27 in the front of the sliding plate 26 extrudes the sliding block 28 to slide towards the middle part, the two L-shaped rods 29 are pulled to drive the vertical plate 30 to approach each other, the limiting plate 32 is matched with the spring telescopic rod 31 to limit and fix the two sides of the human body, the situation that the deviation of the compression hemostasis position occurs due to the fact that the body of a patient moves when compression hemostasis occurs can be effectively avoided, the effect of restraining a sleeping patient can be achieved, and the phenomenon that the wound of the patient is torn and pulled to bleed due to the fact that the action amplitude of the patient is too large is prevented;
the above structure movement process refers to fig. 1, 9 and 10.
Before use, the support frame 1 is integrally placed on a hospital bed, two suckers 91 are attached to stainless steel parts of a bed surface, then when the vertical plates 30 are close to each other, the two guide rods 97 are synchronously driven to move towards the middle, when the guide rods 97 move, the lower ends of the guide rods 97 abut against the upper right end of the inclined rod 95 to rotate downwards and drive the first torsion spring 94 to contract, so that the lower left end of the inclined rod 95 pulls the piston plate 92 to move upwards through the telescopic pull rod 96, air in the inner cavity of the suckers 91 can be upwards pumped out, the suckers 91 are adsorbed to the bed surface of the hospital bed more tightly, the effect of automatically installing the support frame 1 to the bed surface is achieved, the phenomenon that the bleeding prevention device is simply placed on the bed surface and topples to the wound of a patient is avoided, the placing stability and safety of the bleeding prevention device in compression hemostasis are guaranteed, when the subsequent guide rods 97 move and reset, the first torsion spring 94 rebounds to drive the inclined rod 95 to rotate and reset, the piston plate 92 is driven to move downwards, so that the vacuum pressure in the suckers 91 gradually reduces the suction force and weakens gradually, and then the sucker 91 becomes loose;
the above structure movement process refers to fig. 1, 9 and 11.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
