[0046] It can be seen that before the instrument carrier 6 is unfolded, it can be used as a barrier to block the patient on the stretcher body 1 to reduce the risk of the patient falling. The instrument tray 23 is flipped outward until the instrument tray 23 bypasses the upper end of the inverted U-shaped frame 22 and flips to a position above the stretcher body 1. The instrument tray 23 is lifted by the anti-rotation support 31, and the rotation of the instrument tray 23 is limited during the passage to prevent the instrument tray 23 from continuing to rotate. The unfolded instrument tray 23 can be used to place medical instruments to prevent the medical instruments from being directly placed on the stretcher body 1 and coming into contact with the patient.

[0047] A guide rail 7 is provided at the bottom of the stretcher body 1 and between the stretcher body 1 and the support frame group 2. The guide rail 7 is used to guide the stretcher body 1 during the process of being placed on the upper end of the support frame group 2. The guide rail 7 is also used to limit the movement of the stretcher body 1 after it is placed on the upper end of the support frame group 2. Specifically, the guide rail 7 includes a lifting plate 25 and a guide buckle seat 28. The lifting plate 25 is fixedly connected to the support frame group 2, and the guide buckle seat 28 is fixedly connected to the stretcher body 1. A guide round rod 26 is fixedly connected to the upper end of the lifting plate 25 and along the length direction.

[0049] The stretcher body 1 can be lifted from the upper end of the support frame group 2 by the handle 8, so that the stretcher body 1 can be used independently. After the stretcher body 1 is placed on the upper end of the support frame group 2, the cooperation between the guide buckle seat 28 and the guide round rod 26 can effectively prevent the stretcher body 1 from lateral horizontal movement. The end of the guide buckle seat 28 is limited by the limit block 27, so that the horizontal movement of the stretcher body 1 can be further limited, thereby improving the stability of the stretcher body 1 after being placed on the upper end of the support frame group 2.

[0050] Embodiment 2:

[0051] The multifunctional transport stretcher based on cardiopulmonary resuscitation provided in Example 1 is further optimized. Specifically, Figure 7 As shown, the infusion stand body 13 includes a rotating base 17, which is rotatably connected to the L-shaped telescopic sleeve rod 15. A plurality of movable frames 18 are arranged in a circular array on the outer side of one end of the rotating base 17 away from the L-shaped telescopic sleeve rod 15. One end of the movable frame 18 is rotatably connected to the rotating base 17. A torsion spring is arranged at the connection between the movable frame 18 and the rotating base 17. A limiting collar 20 is sleeved on the outer side of the rotating base 17, and the end of the limiting collar 20 close to the movable frame 18 is funnel-shaped, so that when the limiting collar 20 slides, it can drive the plurality of movable frames 18 to gather and fold. An anti-slip pad 19 is fixedly connected to the outer side of the movable frame 18.

[0052] Through the above structural design, when the movable frame 18 is folded, the torsion spring is in a force storage state, so that the limiting ring 20 is moved away from the position of the movable frame 18 by sliding the limiting ring 20, and then the movable frame 18 is driven to expand outward by the torsion spring to release the stored force, thereby providing a suspended frame structure for infusion. After use, the plurality of movable frames 18 can be gathered and folded by sliding the limiting ring 20 to the position of the movable frame 18; when the infusion frame body 13 is in the folded state, the infusion frame body 13 and the L-shaped movable rod 14 are rotated and reset, and the lower end of the infusion frame body 13 can be inserted into the interior of the connecting seat 2 10 by moving the L-shaped movable rod 14 and the L-shaped telescopic sleeve rod 15 downward, and the friction force can be increased by the anti-slip pad 19 on the outer side of the movable frame 18, so as to reduce the occurrence of the infusion frame body 13 accidentally falling out of the connecting seat 2 10.

[0053] Embodiment 3:

[0054] The multifunctional transport stretcher based on cardiopulmonary resuscitation provided in Example 1 is further optimized. Specifically, Fig.13 As shown, the positioning groove includes an arc-shaped positioning groove 29, and the guide buckle seat 28 is fitted with the upper part of the guide round rod 26 through the arc-shaped positioning groove 29. Both ends of the arc-shaped positioning groove 29 are provided with guiding inclined surfaces 30 for guiding the guide round rod 26 during the fitting process with the arc-shaped positioning groove 29.

[0055] Through the above-mentioned structural design, when the stretcher body 1 is placed on the upper end of the support frame group 2, the guide round rod 26 can be guided by the guiding inclined surface 30 so that it can accurately enter the arc-shaped positioning groove 29. Through the fit between the arc-shaped positioning groove 29 and the guiding round rod 26, the effect of limiting the lateral horizontal movement of the stretcher body 1 is achieved.
