Description

Technical Field

[0001] The utility model relates to the technical field of medical appliances, in particular to a medical teaching demonstration device. Background Art

[0002] The existing medical nursing teaching demonstration device includes a table and an infusion stand. The infusion stand is provided with a hook for hanging an infusion bottle, so as to demonstrate while explaining. In addition, in order to clearly show the teacher's demonstration process for more students to watch at the same time, the nursing teaching demonstration device is also equipped with a camera and a display screen. However, as a high-value device, the display screen is exposed to the outside for a long time when not in use, which is less safe and easy to be damaged by external collision and malfunction due to dust and rain.

[0003] The existing Chinese patent CN219626143U discloses a medical teaching demonstration device, which uses an electric push rod to adjust the height of the display, and can adjust the display orientation by rotation, so that the demonstration effect is better. After the demonstration is completed, the electric push rod can be retracted to retract the display screen into the first storage cavity for storage, so as to avoid the display screen being exposed when not in use, thereby improving the safety of the display screen;

[0004] However, the above-mentioned medical teaching demonstration device stores the display in the first storage cavity, and because the display and the electric push rod are rotatably connected, the display stored in the first storage cavity can be rotated. When an external force collides with the medical teaching demonstration device, the display is easily affected by the vibration of the impact and rotates, and the edge of the display after rotation will collide with the inner wall of the first storage cavity, thereby causing damage to the display.

The rotating shaft 635 is rotatably connected to the rotating shaft 635, and a rotating cover 633 is fixedly installed on the outer wall of the rotating shaft 635. The rotating cover 633 is clamped in the groove 631. The bottom of the rotating cover 633 is provided with a clamping slot 634, and the top of the display screen 614 is clamped in the clamping slot 634. The top of the storage cavity 611 is shielded by the rotating cover 633 to protect the display screen 614 in the storage cavity 611. The top of the display screen 614 is clamped in the clamping slot 634, and the display screen 614 can be re-operated. To further prevent the display screen 614 from rotating in the storage chamber 611, a connecting block 637 that can move up and down is provided to connect the rotating shaft 635 and the rotating cover 633, so that when the rotating cover 633 is covered on the storage chamber 611, it can be covered by moving vertically downward to ensure that the card slot 634 can be aligned with the top of the display screen 614, a sliding rod 638 is provided to limit the connecting block 637 to prevent the connecting block 637 from falling off, and a spring 636 is provided to push the sliding rod 63 downward 8, and then push the connecting block 637 downward, and use the elastic force of the spring 636 to press the rotating cover 633 into the groove 631. The left inner wall of the groove 631 is provided with an escape groove 7, and the escape groove 7 extends to the left side of the device body 1. After the display screen 614 extends out of the storage cavity 611, the rotating cover 633 can be rotated so that the rotating cover 633 enters the escape groove 7, exposing the entire top of the storage cavity 611, thereby preventing the rotating cover 633 from pressing on the left outer wall of the display screen 614.

[0029] Working principle: When in use, the medical demonstration process is filmed through the camera 5, and then displayed to students through the display screen 614. After use, the electric telescopic rod 612 is turned on to drive the connecting seat 613 to move downward, thereby driving the display screen 614 to move downward, and the display screen 614 is moved from the outside into the storage chamber 611. In the process of the electric telescopic rod 612 driving the connecting seat 613 to move downward, the electric telescopic rod 612 drives the connecting plate 625 to move downward, thereby driving the rack 623 to move downward, and the rack 623 moves downward so that the gear 624 drives the screw rod 628 to rotate, and the rotation of the screw rod 628 causes the rectangular column 627 moves to the left until the left end of the rectangular column 627 extends into the rectangular groove 626, limiting the connection seat 613 and then limiting the display screen 614, pulling up the connection block 637 to drive the rotating shaft 635 to move upward, and then driving the rotating cover 633 to move upward, and then rotating the rotating cover 633 so that the rotating cover 633 faces the groove 631, and after loosening the rotating cover 633, the spring 636 pushes the sliding rod 638 to move downward, thereby driving the connection block 637 to move downward, so that after the rotating cover 633 moves downward, the top of the display screen 614 is stuck in the slot 634, completing the storage of the display screen 614.

[0030] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.
