Specific embodiments

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0025] Embodiment 1

[0026] The present invention provides a convenient dressing-changing stent for diabetic foot wounds, as Figures 1 to 5 shown, including: a base 1, the top end of the base 1 is rotatably connected to an outer sleeve 2, anti-slip blocks 9 are embedded and installed at the four corners of the bottom end of the base 1, a tray 3 for placing medical supplies is welded on the outside of the outer sleeve 2, a lifting sleeve 4 is vertically movably connected inside the outer sleeve 2, and an arc support seat 5 for placing the patient's leg is embedded and installed at the top end of the lifting sleeve 4;

[0027] The top end inner wall of the outer sleeve 2 is rotatably connected to a rotating sleeve 8, a longitudinal plate 19 is horizontally movably connected inside the rotating sleeve 8, a longitudinal positioning block 14 for rotational fixation is embedded and installed at the bottom end of the longitudinal plate 19, one end of the longitudinal plate 19 is synchronously movably connected to a limiting plate 15, and one end of the limiting plate 15 is movably connected to a vertical positioning block 20 for vertical fixation.

[0028] As Figure 2 and Figure 3As shown, the inner wall of the outer sleeve 2 is rotatably connected to the inner sleeve 6. Inside the inner sleeve 6, an L-shaped ring 7 is rotatably connected. At a position corresponding to the outside of the L-shaped ring 7 inside the inner sleeve 6, a fitting groove is provided. The bottom end and the top end of the rotating sleeve 8 are fixedly connected;

[0029] It can facilitate the rotation of the rotating sleeve 8, change the rotation difficulty of the rotating sleeve 8, and can limit the position when the rotating sleeve 8 rotates, preventing the problem of deviation when the rotating sleeve 8 rotates.

[0030] As Figure 2 and Figure 3 shown, a screw rod 12 is connected inside the outer sleeve 2 and the rotating sleeve 8 by threads. A bearing 13 is installed at the position of the outer side of the screw rod 12 inside the rotating sleeve 8 by interference fit. The outer ring of the bearing 13 and the inner wall of the longitudinal positioning block 14 are in interference fit. The limiting plate 15 is horizontally slidably connected inside the rotating sleeve 8;

[0031] It can facilitate the rotation of the screw rod 12, so that the screw rod 12 cannot drive the longitudinal positioning block 14 to rotate when rotating, and under the action of limiting, the longitudinal positioning block 14 performs a horizontal displacement along the inside of the rotating sleeve 8.

[0032] As Figure 2 and Figure 3 shown, one end of the screw rod 12 is rotatably connected to a moving plate 17 at the position inside the lifting sleeve 4. Two positioning columns 16 penetrate through the moving plate 17, and one ends of the two positioning columns 16 are welded to the inner wall of the rotating sleeve 8;

[0033] It can facilitate the limitation of the movement of the moving plate 17, prevent the problem of deflection when the moving plate 17 moves, and thus make the movement of the moving plate 17 more stable.

[0034] As Figure 2 and Figure 3 shown, connecting columns 18 are symmetrically embedded at one end face of the moving plate 17, and one end faces of the two connecting columns 18 are fixedly connected to one end face of the longitudinal plate 19;

[0035] It can facilitate the synchronous movement of the longitudinal plate 19 and the moving plate 17, and change the synchronous movement difficulty of the longitudinal plate 19 and the moving plate 17.

[0036] As Figure 2 and Figure 3 shown, a clamping groove 10 is provided at the bottom of the outer surface of the rotating sleeve 8, and a positioning groove 11 is provided at the bottom of the outer surface of the lifting sleeve 4;

[0037] It is convenient for the longitudinal positioning block 14 and the vertical positioning block 20 to be connected thereto, so as to achieve the purpose of fixing the positions of the lifting sleeve 4 and the rotating sleeve 8, and prevent the problems of shaking of the lifting sleeve 4 and the rotating sleeve 8 from occurring.

[0038] As Figure 2 and Figure 4 shown, a limiting plate 21 is embedded and installed in the middle of the top end of the base 1, a piston plate 22 is clamped and installed on the top of the outer surface of the limiting plate 21, the lifting sleeve 4 is slidably connected to the outside of the piston plate 22, and the outer side of the limiting plate 21 and the edge of the inner wall of the lifting sleeve 4 are mutually attached;

[0039] It is convenient to limit the movement of the lifting sleeve 4 and prevent the problem of deflection when the lifting sleeve 4 moves up and down.

[0040] As Figure 2 and Figure 4 shown, a conical sleeve 23 is fixedly installed inside the limiting plate 21, a horizontal rod 24 is fixedly installed inside the piston plate 22, spring telescopic rods 25 are symmetrically embedded and installed at the bottom end of the horizontal rod 24, and a conical cover 26 is clamped and installed between the bottom ends of the two spring telescopic rods 25, and a triangular block 27 is fixedly installed at the bottom end of the conical cover 26;

[0041] Under the action of the triangular pants 27, it is convenient for the outside gas to enter the inside of the lifting sleeve 4, and under the action of the horizontal rod 24, it is used for the installation of the conical cover 26. At the same time, under the action of the spring telescopic rod 25, it is convenient for the movement and reset of the conical cover 26, and changes the difficulty of the movement and reset of the conical cover 26.

[0042] As Figure 2 and Figure 4 shown, the bottom diameter of the conical cover 26 is smaller than the top diameter, the top diameter of the conical sleeve 23 is larger than the bottom diameter, the conical cover 26 is located inside the conical sleeve 23 and the center lines of the conical cover 26 and the conical sleeve 23 coincide with each other;

[0043] When the arc-shaped support base 5 descends rapidly, the gas inside the lifting sleeve 4 is rapidly compressed at this time. Since the distance between the conical cover 26 and the conical sleeve 23 is smaller than the gas outflow speed, the internal pressure increases at this time. The increased pressure drives the conical cover 26 to move. When the conical cover 26 moves, it drives the spring telescopic rod 25 to stretch. At this time, the distance between the conical cover 26 and the conical sleeve 23 becomes smaller again, so that the descending speed of the arc-shaped support base 5 is reduced, and the problem of the rapid dropping of the arc-shaped support base 5 in the prior art is changed.

[0044] Working principle: Place the base 1 on a stable position on the bed, ensure that the anti-slip blocks 9 installed at the four corners of the bottom end of the base 1 are closely attached to the ground of the bed to prevent the bracket from sliding during use. Then place the required medical supplies on the tray 3 welded to the outside of the outer sleeve 2 for easy access during the dressing change process;

[0045] Then rotate the screw 12. When the screw 12 rotates, it drives the longitudinal positioning block 14 to move through the bearing 13. The longitudinal positioning block 14 moves horizontally under the limitation of the limiting plate 15, and at the same time drives the moving plate 17 to move outside the positioning column 16. At this time, the vertical positioning block 20 and the longitudinal positioning block 14 are separated from the rotating sleeve 8 and the lifting sleeve 4 respectively, so that the lifting sleeve 4 inside the outer sleeve 2 and the rotating sleeve 8 move up and down, thereby adjusting the height of the arc-shaped support seat 5 to adapt to the height requirements of the patient's leg;

[0046] After the height is adjusted, at this time rotate the screw 12. The screw 12 drives the longitudinal positioning block 14 to move through the bearing 13. The longitudinal positioning block 14 moves horizontally under the limitation of the limiting plate 15, and at the same time drives the moving plate 17 to move outside the positioning column 16. At this time, the vertical positioning block 20 coincides with the lifting sleeve 4. When the clamping groove 10 of the vertical positioning block 20 and the lifting sleeve 4 is initially fitted, at this time the longitudinal positioning block 14 cannot be fitted with the positioning groove 11. When the screw 12 is rotated, the rotating sleeve 8, the outer sleeve 2 and the tray 3 at the bottom end of the screw 12 rotate. This method changes the way in the prior art that the entire bracket needs to be displaced during the process of changing the direction of the tray 3 due to the inaccurate placement position of the tray 3. This method is convenient for personnel to change dressings, and at the same time changes the fixing method by extrusion of the screw 12 in the prior art. This method uses a clamping method to make the position after vertical clamping more stable and prevent the problem of self-sliding due to excessive force;

[0047] Then rotate the screw 12 to drive the longitudinal positioning block 14 to move through the bearing 13. The longitudinal positioning block 14 moves horizontally under the limitation of the limiting plate 15, and at the same time drives the moving plate 17 to move outside the positioning column 16. At this time, the vertical positioning block 20 and the longitudinal positioning block 14 completely coincide with the rotating sleeve 8 and the lifting sleeve 4 respectively, so that the positions of the tray 3 and the lifting sleeve 4 are completely fixed;

[0048] Finally, when it is necessary to adjust the height of the buffer arc support base 5, the screw rod 12 is rotated reversely at this time. Since the patient's leg presses on the arc support base 5, when the arc support base 5 drops rapidly, the gas inside the lifting sleeve 4 is rapidly compressed. Since the distance between the conical cover 26 and the conical sleeve 23 is less than the gas outflow speed, the internal pressure increases. The increased pressure drives the conical cover 26 to move. When the conical cover 26 moves, it drives the spring telescopic rod 25 to stretch, making the distance between the conical cover 26 and the conical sleeve 23 smaller again, thereby reducing the descending speed of the arc support base 5 and preventing it from falling rapidly, protecting the patient's leg from injury.

[0049] Finally, place the patient's leg on the arc support base 5 to ensure that the leg is comfortable and stable. Then the medical staff takes medical supplies from the tray 3 and performs a dressing change operation on the patient's foot wound. Since the height and angle of the bracket can be adjusted, the medical staff can adjust according to actual needs, improving the dressing change efficiency and quality.

[0050] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
