Description

Technical Field

[0001] This invention relates to the field of transport stretcher technology, and in particular to a multifunctional transport stretcher based on cardiopulmonary resuscitation. Background Technology

[0002] Stretchers are commonly used emergency equipment for transporting critically ill patients. Currently, commonly used stretchers have relatively limited functions, serving only as a single unit during the transport of critically ill patients. Furthermore, the transport of critically ill patients often requires cardiopulmonary resuscitation (CPR), oxygen administration, and intravenous infusion. Traditional stretchers are inconvenient to carry, often requiring the placement of necessary equipment on the stretcher, which can easily lead to collisions with the patient. Infusions also require manual lifting, and stretchers with attached IV stands are space-consuming when not in use, or require disassembly of the IV stand, causing inconvenience. Therefore, this application proposes a multifunctional transport stretcher based on cardiopulmonary resuscitation, providing a new technical solution to address the aforementioned technical problems. Summary of the Invention

[0003] Therefore, it is necessary to address the aforementioned technical problems by providing a multifunctional transport stretcher based on cardiopulmonary resuscitation. Through the structural design of the instrument rack assembly and the instrument support frame, the device can carry multiple medical devices. In use, the instrument support frame can be unfolded to provide a platform for placing medical devices, thereby avoiding the phenomenon of medical devices being placed directly on the upper part of the stretcher body and coming into contact with the patient. Furthermore, through the structural design of the infusion stand assembly, when the device needs to administer intravenous infusion to the patient, the infusion stand assembly can be unfolded to provide a hanging frame structure for infusion. When not in use, the infusion stand assembly can be folded up to reduce space occupation.

[0039] To enable those skilled in the art to better understand the present invention, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0040] Example 1:

[0041] Please refer to Figure 1 - Figure 12 A multifunctional transport stretcher based on cardiopulmonary resuscitation, comprising:

[0042] The stretcher body 1 has a support frame assembly 2 below it. The stretcher body 1 is placed above the support frame assembly 2. The lower end of the support frame assembly 2 is fixedly connected to a movable frame assembly 3. An instrument rack assembly 4 is provided inside the movable frame assembly 3 for placing medical instruments.

[0043] An IV stand assembly 5 is installed on one side of the stretcher body 1. The IV stand assembly 5 is fixedly connected to the support frame assembly 2. Before being deployed, the IV stand assembly 5 serves as a support to prevent the patient from falling. After being deployed, the IV stand assembly 5 provides support for IV infusion. Specifically, the IV stand assembly 5 includes a first connecting seat 9 and a second connecting seat 10. Both the first connecting seat 9 and the second connecting seat 10 are fixedly connected to the support frame assembly 2. The upper ends of the first connecting seat 9 and the second connecting seat 10 are respectively provided with an L-shaped movable rod 14 and an L-shaped telescopic sleeve rod 15. The L-shaped movable rod 14 and the L-shaped telescopic sleeve rod 15 are slidably connected. A limit knob 16 is provided on the outer side of the L-shaped telescopic sleeve rod 15 and at the end near the L-shaped movable rod 14. A sliding seat 12 is rotatably connected to the end of the L-shaped movable rod 14 away from the L-shaped telescopic sleeve rod 15. The sliding seat 12 is vertically slidably connected to the connecting seat 1 9. An infusion stand body 13 is rotatably connected to the end of the L-shaped telescopic sleeve rod 15 away from the L-shaped movable rod 14. The infusion stand body 13 is vertically inserted into the connecting seat 2 10. To limit the rotation of the L-shaped movable rod 14 and the infusion stand body 13, limit rings 11 are provided at the connection between the L-shaped movable rod 14 and the sliding seat 12, and at the connection between the L-shaped telescopic sleeve 15 and the infusion stand body 13. The L-shaped movable rod 14 and the L-shaped telescopic sleeve 15 are fixedly connected to the limit rings 11. A protrusion is provided on the outer side of the limit ring 11, and a locking groove that mates with the protrusion is provided on the inner side of both the sliding seat 12 and the infusion stand body 13. In other embodiments, fastening screws are provided on both the sliding seat 12 and the infusion stand body 13 at positions corresponding to the limit rings 11. After each rotation, the rotation can be limited by tightening the fastening screws.

[0044] It can be seen that before the IV stand assembly 5 is deployed, it can act as a barrier to prevent the patient from falling off the stretcher body 1, thus reducing the risk of the patient falling. This is useful when an IV infusion is needed. Figure 4 As shown, the L-shaped movable rod 14 and the L-shaped telescopic sleeve rod 15 can be pulled upwards, thereby moving the sliding seat 12 and the infusion stand body 13 upwards, separating the bottom of the infusion stand body 13 from the connecting seat 10, as shown. Figure 5 As shown, the L-shaped movable rod 14 drives the L-shaped telescopic sleeve rod 15 to rotate to an upright position, as... Figure 6 As shown, rotating the infusion stand 13 to an upright position provides a suspended support structure for infusion. The height of the L-shaped telescopic sleeve 15 can be adjusted as needed. Tightening the limiting knob 16 limits the movement of the L-shaped telescopic sleeve 15, thus adjusting the height of the infusion stand 13. In other embodiments, a limiting knob is provided on the upper part of the connecting seat 9. After each movement of the sliding seat 12, tightening the limiting knob limits the movement of the sliding seat 12.

[0045] On the other side of the stretcher body 1, there is an instrument support frame 6. The instrument support frame 6 is fixedly connected to the support frame group 2. Before the instrument support frame 6 is unfolded, it is used as a guard to prevent the patient from falling. After the instrument support frame 6 is unfolded, it is used as a guard and also as a temporary placement platform for medical devices. Specifically, the instrument support frame 6 includes an inverted U-shaped frame 22. Both ends of the inverted U-shaped frame 22 are fixedly connected to the connecting seat 3 21. The connecting seat 3 21 is fixedly connected to the support frame group 2. An instrument tray 23 is provided on the inner side of the inverted U-shaped frame 22. The instrument tray 23 is rotatably connected to the inverted U-shaped frame 22 through the connecting ring 24. A rotation-stopping support 31 is horizontally fixedly connected to the side of the inverted U-shaped frame 22 near the stretcher body 1. The rotation-stopping support 31 is used to limit the rotation of the instrument tray 23.

[0046] It can be seen that before the instrument support frame 6 is unfolded, it can act as a barrier to block the patient on the stretcher body 1, reducing the risk of the patient falling. By flipping the instrument tray 23 outward until the instrument tray 23 passes over the upper end of the inverted U-shaped frame 22 and flips to a position above the stretcher body 1, the anti-rotation support 31 lifts the instrument tray 23. When passing through, the rotation limit of the instrument tray 23 is achieved, preventing the instrument tray 23 from continuing to rotate. After the instrument tray 23 is unfolded, it can be used to place medical devices, avoiding the medical devices being placed directly 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 it and the support frame assembly 2. The guide rail 7 is used to guide the stretcher body 1 during the process of placing it on the upper end of the support frame assembly 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 assembly 2. Specifically, the guide rail 7 includes a lifting plate 25 and a guide buckle 28. The lifting plate 25 is fixedly connected to the support frame assembly 2, and the guide buckle 28 is fixedly connected to the stretcher body 1. A guide rod 26 is fixedly connected to the upper end of the lifting plate 25 along its length. Limit blocks 27 are fixedly connected to the upper end of the lifting plate 25 at both ends of the guide rod 26. A positioning groove is provided at the lower end of the guide buckle 28, and the guide buckle 28 is fastened to the guide rod 26 through the positioning groove.

[0048] Handles 8 are fixedly connected to the sides of the stretcher body 1 and near both ends, providing a grip for lifting or moving the stretcher body 1.

[0049] The stretcher body 1 can be lifted from the upper end of the support frame assembly 2 by means of 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 assembly 2, the cooperation between the guide buckle 28 and the guide rod 26 can effectively prevent the stretcher body 1 from moving laterally. The end of the guide buckle 28 is limited by the limit block 27, which can further limit the horizontal movement of the stretcher body 1, thereby improving the stability of the stretcher body 1 after it is placed on the upper end of the support frame assembly 2.

[0050] Example 2:

[0051] The multifunctional transport stretcher based on cardiopulmonary resuscitation provided in Example 1 has been further optimized, specifically, as follows: Figure 7 As shown, the infusion stand body 13 includes a rotating base 17, which is rotatably connected to an L-shaped telescopic sleeve 15. Multiple movable frames 18 are arranged in a circular array on the outer side of the rotating base 17 away from the L-shaped telescopic sleeve 15. One end of the movable frame 18 is rotatably connected to the rotating base 17. A torsion spring is provided 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 near the movable frame 18 is funnel-shaped, so that when the limiting collar 20 slides, it can drive the multiple movable frames 18 to gather and fold together. 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 stored state. Thus, by sliding the limiting collar 20, the limiting collar 20 is moved away from the position of the movable frame 18, and the movable frame 18 is then released by the torsion spring to drive the movable frame 18 to unfold outward, thereby providing a suspended frame structure for infusion. After use, by sliding the limiting collar 20 back to the position of the movable frame 18, multiple movable frames 18 can be gathered and folded. When the infusion frame 13 is in the folded state, the infusion frame 13 and the L-shaped movable rod 14 are rotated back to their original positions. By moving the L-shaped movable rod 14 and the L-shaped telescopic sleeve 15 downward, the lower end of the infusion frame 13 can be inserted into the connecting seat 2 10. The anti-slip pad 19 on the outside of the movable frame 18 can increase the friction and reduce the occurrence of the infusion frame 13 accidentally falling out of the connecting seat 2 10.

[0053] Example 3:

[0054] The multifunctional transport stretcher based on cardiopulmonary resuscitation provided in Example 1 has been further optimized, specifically, as follows: Figure 13 As shown, the positioning groove includes an arc-shaped positioning groove 29. The guide buckle 28 fits against the upper part of the guide rod 26 through the arc-shaped positioning groove 29. Both ends of the arc-shaped positioning groove 29 are provided with guide slopes 30, which are used to guide the rod 26 during the fitting process with the arc-shaped positioning groove 29.

[0055] Through the above structural design, during the process of placing the stretcher body 1 on the upper end of the support frame assembly 2, the guide ramp 30 can guide the guide rod 26 so that it can accurately enter the arc-shaped positioning groove 29. Through the fit between the arc-shaped positioning groove 29 and the guide rod 26, the effect of limiting the lateral horizontal movement of the stretcher body 1 is achieved.

[0056] Example 4:

[0057] The multifunctional transport stretcher based on cardiopulmonary resuscitation provided in Example 1 is further optimized. Specifically, the medical devices placed inside the instrument rack group 4 include at least a cardiopulmonary resuscitation machine, a ventilator, a defibrillator, and a first aid kit.
