Description

Technical Field

[0001] The utility model belongs to the technical field of medical stretchers, in particular to an operating stretcher. Background Art

[0002] Surgical trolleys, patient carriers are a type of medical equipment that is mainly used to transfer patients from one place to another, such as from a ward to an operating room or an examination room. It is one of the essential equipment in a hospital, providing safe, comfortable and convenient patient transfer services.

[0003] The length of the existing surgical trolley is generally between 185-210CM. During emergency transfer, medical staff use elevators to move the trolley. When there is no patient on the trolley, due to the length limitation, only the special surgical elevator can be used to go up and down the stairs, and some small elevators cannot be used for transportation. If the special surgical elevator is full and needs to wait, it will undoubtedly waste emergency time. Therefore, the inventor has set up a foldable trolley. When there is no patient on the bed, it can be folded up and taken up and down the stairs by a small elevator to save emergency time. Utility Model Content

[0043] Embodiment: A surgical trolley as shown in FIG1 includes a body 10 and a stretcher assembly 20 disposed above the body 10;

[0044] As shown in FIG. 2 , the vehicle body 10 comprises a frame body composed of four groups of connecting rods 102 at the bottom, a sundries frame 104 is fixedly connected to the bottom of the frame body for placing sundries, and a support frame 101 is also arranged above the frame body, and two groups of supporting rods 110 are arranged between the support frame 101 and the frame body, wherein, as shown in FIG. 2 , the four connecting rods 110 of the support frame 101 are arranged on the top of the frame body.

[0045] The side is fixedly mounted on the upper end of the support rod 110, and the lower frame is fixedly connected to the lower side wall of the support rod 110 to form a cubic structure. An infusion rod 109 is also provided at the upper end of the support frame 101 to facilitate the hanging of the infusion bottle;

[0046] As shown in FIG. 2 , in order to facilitate the movement of the vehicle body 10 , a universal wheel 105 is installed at the lower end of the support rod 110 on one side, and a large wheel 106 is installed at the lower end of the support rod 110 on the other side, so that the vehicle body 10 can be moved easily.

[0047] 10 Flexible turning and easy to move;

[0048] Guardrails 107 are also provided on both sides of the support frame 101. The lower end of the guardrail 107 is fixedly connected to a flip member 108. The flip member 108 is movably sleeved on the outer side of the horizontal rod of the support frame 101. The flip member 108 and the support frame 101 are connected to each other.

[0049] Torsion springs may be provided between the transverse rods so that the flip member 108 can be quickly reset;

[0050] The stretcher assembly 20 shown in FIG. 2 includes a stretcher body 202 and a movable flip stretcher

[0051] A limit hinge as shown in FIG3-4 is also provided between the stretcher body 202 and the flip stretcher 201.

[0052] 30, the rotation angle of the limit hinge 30 is 0-90 degrees. When there is no patient on the surgical trolley, the

[0053] The flip stretcher 201 is rotated downward 90 degrees to reduce the space occupied by the stretcher, so that it can be easily pushed into a small elevator. When there is a patient, it can be restored to its original state;

[0054] A limit structure is also provided between the stretcher assembly 20 and the vehicle body 10. As shown in FIG. 2, a limit member 203 is integrally formed at the lower end of the stretcher body 202. A limit stopper 103 is fixedly provided inside the support frame 101. When the stretcher assembly 20 needs to be folded, the stretcher assembly 20 can be pulled to one side along the support frame 101.

[0055] When the limit member 203 contacts the limit stop bar 103, the stretcher assembly 20 cannot move further.

[0056] The rotating end of the flip stretcher 201 is located outside the support frame 101, so that the stretcher assembly 20 can be folded;

[0057] The structure of the limit hinge 30 is shown in FIGS. 5-7 , and includes a movable base 301 and a fixed base 302 that are rotatably connected to each other. As shown in FIG. 4 , a second connecting plate 202A is provided below the rotating end of the stretcher body 202 , and a first connecting plate 201A is provided below the rotating end of the flip stretcher 201 . The movable base 301 is fixedly mounted on the first connecting plate 201A, and the fixed base 302 is fixedly connected to the second connecting plate 202A.

[0058] As shown in FIG. 5 and FIG. 6 , a vertical plate a301A is integrally formed on the side of the movable base 301, and an unlocking member 303 is installed on the inner side of the vertical plate a301A. A spring 304 is also provided between the unlocking member 303 and the fixed base 302. As shown in FIG. 5 , a fixed clamping shaft 303A is fixedly connected to the end of the unlocking member 303, and one end of the spring 304 is buckled on the outer side of the fixed clamping shaft 303A.

[0059] The structure of the fixed base 302 is shown in FIG. 7 . The side of the fixed base 302 is also integrally formed with

[0060] The vertical plate b302A has a first slot 302B and a second slot 302C disposed inside the vertical plate b302A.

[0061] When the assembly 20 is unfolded, the fixed card shaft 303A is embedded in the second card slot 302C, and when it needs to be rotated downward by 90 degrees, the fixed card shaft 303A is embedded in the first card slot 302B, and the stretcher assembly 20 is in a folded state at this time. Such a setting enables the stretcher assembly 20 to be easily fixed by the engagement between the card slot and the fixed card shaft 303A regardless of whether it is unfolded or folded;

[0062] In order to meet the movement of the fixed card shaft 303A, a sliding groove 301B is also opened on the vertical plate a301A, and the fixed card shaft 303A can slide along the sliding groove 301B;

[0063] When the limit hinge 30 is rotated downward from 0 degrees to 90 degrees, the unlocking member 303 needs to drive the fixed card shaft 303A to slide along the sliding groove 301B and move out of the second card groove 302C. When there is no external force, the spring 304 pulls the unlocking member 303 to the outer edge of the vertical plate b302A. At this time, the flip stretcher 201 is rotated downward by 90 degrees, so that the fixed card shaft 303A slides along the arc-shaped outer edge of the vertical plate b to the first card groove 302B and is fixed, so that the stretcher assembly 20 completes the whole process from unfolding to folding.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
