Description

Technical Field

[0001] The invention relates to a medical education device, specifically a fully automated multifunctional medical model skill training experimental platform. Background Art

[0002] Medical schools often use medical models for medical skills training and assessment. However, there are many types of medical models, with over a hundred electric models. Medical schools rarely have dedicated laboratories for a specific type of medical model. Utility Model Patent No. 201520197352.0, a chest and abdominal examination training bench, has a low degree of automation. Utility Model Patent No. 20192234473.9, a fully automatic chest and abdominal examination skills training bench, has a significantly improved degree of automation. However, the first tabletop still requires manual removal and insertion into a chute behind the main frame of the bench. The chest and abdominal models are then automatically raised by operating a lifting switch. After training is complete, the chest and abdominal models are manually removed from the chute behind the main frame and placed on the second tabletop, which is not truly fully automated. The screw rod and nut used in the bench's lifting mechanism are noisy, and the anti-horizontal deviation device is ineffective. Furthermore, the chest and abdominal models in the above two patents are fixed to the second tabletop, essentially serving as dedicated benches for chest and abdominal examination skills training, resulting in a waste of laboratory and bench equipment resources.

[0020] The main structure of the test bench is made according to the drawings, using steel plates cut, bent, welded, and painted. The medical model skin and soft tissue are molded using PVC or silicone rubber, and the simulated skeleton is molded using hard plastic or unsaturated plastic. The mechanical components are manufactured according to the drawings, and other parts are commercially available. Once the parts are assembled and debugged according to the instructions and the accompanying drawings, the test bench is ready for use. When conducting skill training on a vertical medical model, preparations should be made before the actual training. If an electronic educational medical model equipped with electrical devices is used, the cables, data cables, audio cables, etc. should be connected to the corresponding computer and other electrical equipment through the circular hole 6-1 in the center of the liftable table A (5) of the experimental table. Pull the computer keyboard and mouse out of the keyboard slide, adjust the computer LCD monitor to a suitable position through the universal bracket, and then place the medical model 3-1 / 3-n on the liftable table A5. Since the feet of the vertical medical model have been replaced with 4 round strong magnets CP, they can be adsorbed on the liftable table A5 made of steel plate through strong magnetic force, so that the model is automatically fixed. Therefore, it will not shake during teaching medical skill training or assessment operations. Press the main power switch K1 of the experimental bench controller and the indicator light LED1 lights up. When using the vertical medical model 1-1 / 1-n for skill training or assessment, press the "A Up" key K2 of the experimental bench controller and the indicator light LED2 lights up. The DC motor M1 starts to drive the bearing screw 8 to rotate forward. Since the nut 9 matching the bearing screw 8 is connected to the steel support plate 11 through the flange 10 and is fixed to the bottom surface of the liftable table A5 of the vertical medical model experimental table A with screws, therefore, due to the forward rotation of the bearing screw 8, when the nut 9 is driven to rise, the flange 10 drives the steel support plate 11 to lift the liftable table 5, and the upper end of the vertical medical model 1-1 / 1-n on the table gradually lifts the upper table 12 of the experimental table A. Therefore, under the upward force of the DC motor-bearing screw, the elastic potential energy generated by the compressed high-pressure liquid in the hydraulic spring support rod 13 is released and converted into an upward elastic force. This acts on table A 5, causing it to rotate 90° around the axis of rotation, transforming vertical medical mannequins 1-1 / 1-n and rotating to the rear vertical medical mannequins 1-1 / 1-n. During this process, the elastic pull rope 14 is stretched by the upward force of the hydraulic spring support rod 13, storing elastic potential energy. At this point, the upper table 12 of the laboratory table is automatically opened. Simultaneously, the liftable table 5 and the vertical medical mannequins 1-1 / 1-n placed thereon rise to the optimal height limit for practical training, triggering limit switch K3 to automatically shut off power, stopping DC motor M1. The computer keyboard and mouse can then be used for skill training or assessment according to the routine training procedures for this medical mannequin.At the end of the training session, press the "A Down" button K2 on the lab bench controller, causing the reduction motor to reverse, nut 9 to gradually lower the liftable surface of lab bench A. The stored elastic potential energy of elastic traction rope 14 is released, and the elastic tension pulls upper surface A downward about axis ZZ. The upper surface A12 of lab bench A then tilts 90 degrees downward about axis ZZ, assuming a horizontal position and automatically covering the upper surface 12 of lab bench A. Simultaneously, when liftable surface A5 reaches the bottom of the lab bench, it triggers limit switch K4, automatically shutting off power and stopping DC motor M1. This completes the automatic stowage of vertical medical models 1-1 / 1-n on liftable surface 5 of lab bench A. When using a whole-body medical model for skill training or assessment: press the B up button K3 and the electric push rod motor M2 of the scissor-type electric lift will start. Since the scissor-type lift support rods 19-1, 19-2 and the two rear hinged scissor-type lift support rods 19-3, 19-4 are all scissor-hinged in the middle, the ends of the four scissor-type lift support rods are provided with sliders HK-1, HK-2, HK-3, HK-4, which are embedded in the corresponding four slide grooves HC-1, HC-2, HC-3, HC-4. The center position of the four scissor-type lift support rods is hinged with the telescopic end 20 of the electric push rod M) through the front and rear horizontal lifting power LB. The electric push rod M2 of the scissor-type electric lift extends and pushes the scissor-type lift support rods 19-3, 19-4 to drive the moving sliders hk-1—hk-4 to move to the left and right in the slide grooves hc-1—hc-4 away from the center, so that the upper surface B of the laboratory table B is The liftable table 21 on the table lower frame 24 of 21 rises, rises to the limit position and touches the inner limit switch k4 of the electric push rod and the motor stops running. Since the upper end of the fixed slat 22 of the upper table B 21 of the laboratory table B is connected to the rear end of the first transmission rod 23, the front end of the first transmission rod 23 is hinged to the front end of the lower frame 24 of the upper table B 21 of the laboratory table B, the middle part of the first transmission rod 23 is hinged to the second transmission rod 25 and is hinged to the support plate 26 fixed to the lower frame XK of the scissor lift, the rear end of the third transmission rod 27 is hinged to the fixed slat 28 of the upper table B 21 of the laboratory table B, and the front end of the third transmission rod 27 is hinged to the front upper end of the support plate 30; therefore, when the upper table B21 moves upward, the first transmission rod 23 drives the front end of the first transmission rod 23 to make a circular motion backward with the upper end hinge point of the second transmission rod 25 as the fulcrum, and the front end of the third transmission rod 28 also makes a circular motion with the lower end of the second transmission rod 25 as the center of the circle to push the upper table B 21 to move backward. The scissor lift thus causes the upper table 21 to flip backward 90°, turning it from its initial horizontal position to a vertical position, fully opening the upper table 21 of the experimental table B. At this point, skill training or assessment of the horizontal medical model can be conducted according to conventional teaching procedures.At the end of the training, press the "B down" button k4 and the electric push rod M2 will run in the opposite direction, so that the upper table of the scissor-type lifting linkage experimental table B will do a 90° backward flip, so that the upper table B2 will flip forward 90° from the vertical state to the horizontal state, and the upper table B21 of the experimental table B will be completely covered, and the horizontal medical model will be automatically stored in the horizontal model cabinet 4. In this way, the automatic opening and closing of the upper table B2 of the experimental table B is realized. The present invention does not rely on manual removal and storage of medical skills training equipment, and realizes the full automation of opening and closing the table on the experimental table and taking out and storing training equipment. It is easy to change the use function of the experimental table, which can greatly improve the utilization rate of the experimental table, thereby reducing management costs. The dedicated experimental table is transformed into a multi-functional experimental table, and the dedicated laboratory is transformed into a multi-purpose laboratory.
