[0013] The beneficial effects of the utility model are as follows:

[0014] 1. The utility model includes a stretcher main body assembly and a support and adjustment assembly arranged below the stretcher main body assembly. With the support and adjustment of the support and adjustment assembly, the patient is rescued through the stretcher main body assembly. Generally speaking, compared with the conventional medical stretchers, this medical stretcher adopts an adjustable structure, which has a wider application range. It can meet the needs of patients of different ages and different symptoms, and is applicable to the transportation in relatively narrow elevators at the same time. It can be quickly unfolded or retracted using a simple operating principle, which can greatly save the occupied space and is beneficial to the rapid rescue of patients. The stretcher main body assembly includes a main board arranged in a rectangle. Side support boards are correspondingly arranged on the left and right sides of the main board. Auxiliary boards are respectively and rotatably arranged on the front and back sides of the main board through first rotating parts. Two L-shaped bottom boards are symmetrically arranged at the front and back of the bottom of the main board. A plurality of electric push rods are arranged in the left-right direction at the center position corresponding to the bottom of the auxiliary board above the L-shaped bottom board. This setting drives the auxiliary board to rotate upward (downward) through the first rotating part by controlling the simultaneous upward (downward) movement of a plurality of electric push rods, so as to realize the shielding of the patient's side or the auxiliary posture maintenance of the patient who needs to lie on the side. The whole process has a simple principle and is easy to operate, which facilitates the rapid rescue of patients. Of course, a fixing rope (not shown in the figure) for initially fixing the patient is also arranged on the main board. This fixing rope (not shown in the figure) adopts the conventional fixing rope equipped on the medical stretcher in the prior art, and its structure is a known structure in the prior art, so no more details will be described here. The support and adjustment assembly includes sliding grooves correspondingly opened at the center of the bottom of the L-shaped bottom board in the left-right direction. Sliders are correspondingly and slidably arranged symmetrically in the left and right directions in the sliding grooves. A locking mechanism (not shown in the figure) is arranged on the slider. The locking mechanism (not shown in the figure) can adopt a handle-type locking mechanism, a knob-type locking mechanism or other locking mechanisms in the prior art that can realize the locking between the slider and the sliding groove. This embodiment is not limited thereto. The bottom of the slider is rotatably arranged with a support rod through a second rotating part. Adjustment grooves are correspondingly opened on the separated sides of the two support rods arranged front and back. L-shaped adjustment rods are symmetrically arranged at the bottom of the separated ends of the two side support boards in the front and back. Guide parts are arranged on the L-shaped adjustment rods corresponding to the adjustment grooves. The opposite ends of the two L-shaped adjustment rods arranged left and right respectively extend upward to the bottom of the L-shaped bottom board. Universal wheels are rotatably arranged at the bottom of the opposite sides of the two support rods arranged front and back through third rotating parts. This setting can pull the support rod obliquely downward so that it gradually moves obliquely downward through the guiding cooperation between the adjustment groove on it and the guide part. The support rod drives the slider to slide in the sliding groove. At the same time, the support rod changes the angle between it and the slider through the rotation of the second rotating part, that is, the downward inclination angle of the support rod changes accordingly. When the guide part is located at the uppermost end of the adjustment groove, the support rod is fully extended. At this time, the locking between the slider and the sliding groove can be carried out through the locking mechanism (not shown in the figure). Then, the patient can be quickly transported by rolling the universal wheels. The retraction and extension process of the support rod is opposite to this. The whole process has a simple principle and is easy to operate, which facilitates the rapid rescue and transportation of patients.

[0032] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4, Figure 5 , Figure 6 and Figure 7As shown in the figure, it includes a stretcher main body assembly 1 and a support adjustable assembly 2 arranged below the stretcher main body assembly 1. Under the support and adjustment of the support adjustable assembly 2, the patient is rescued through the stretcher main body assembly 1. Generally speaking, compared with the previous medical stretchers, this medical stretcher adopts an adjustable structure, which has a wider application range. It can meet the needs of patients of different ages and different symptoms, and can be applied to the relatively narrow elevator transportation at the same time. It can be quickly unfolded or retracted using a simple operating principle, which can greatly save the occupied space and is beneficial to the rapid rescue of patients; The stretcher main body assembly 1 includes a main board 3 arranged in a rectangle. Side support plates 4 are correspondingly arranged on the left and right sides of the main board 3. The front and rear sides of the main board 3 are respectively rotatably provided with auxiliary boards 6 through first rotating members 5. Two L-shaped bottom plates 7 are symmetrically arranged at the front and rear of the bottom of the main board 3. Above the L-shaped bottom plates 7, a plurality of electric push rods 8 are arranged in the left-right direction corresponding to the center position of the bottom of the auxiliary board 6. This setting drives the auxiliary board 6 to rotate upward (downward) through the first rotating member 5 by controlling the simultaneous rising (falling) of the plurality of electric push rods 8, so as to realize the shielding of the patient's side or the auxiliary posture maintenance of the patient who needs to lie on the side. The whole process has a simple principle and is easy to operate, which facilitates the rapid rescue of patients. Of course, a fixing rope (not shown in the figure) for initially fixing the patient is also arranged on the main board 3. This fixing rope (not shown in the figure) adopts a conventional fixing rope equipped on the medical stretcher in the prior art, and its structure is a known structure in the prior art, so no more details will be given here;The support and adjustment assembly 2 includes sliding grooves 9 correspondingly formed in the central part of the bottom of the L-shaped bottom plate 7 in the left-right direction. Sliders 10 are slidably arranged in the sliding grooves 9 in left-right symmetry. A locking mechanism (not shown in the figure) is provided on the sliders 10. The locking mechanism (not shown in the figure) can adopt a handle-type locking mechanism, a knob-type locking mechanism or other locking mechanisms in the prior art that can lock the sliders 10 and the sliding grooves 9. This embodiment is not limited thereto. The bottom of the slider 10 is rotatably provided with a support rod 12 through a second rotating member 11. Adjustment grooves 13 are correspondingly formed on the separated sides of the two support rods 12 arranged front and rear. L-shaped adjustment rods 14 are symmetrically arranged front and rear at the bottom ends of the separated ends of the two side support plates 4. Guide members 15 are provided on the L-shaped adjustment rods 14 corresponding to the adjustment grooves 13. The opposite ends of the two L-shaped adjustment rods 14 arranged left and right extend upward to the bottom of the L-shaped bottom plate 7 correspondingly. Universal wheels 17 are rotatably provided at the bottom of the opposite sides of the two support rods 12 arranged front and rear through third rotating members 16. This setting can pull the support rod 12 obliquely downward so that it gradually moves obliquely downward through the guiding cooperation between the adjustment groove 13 on it and the guide member 15. The support rod 12 drives the slider 10 to slide in the sliding groove 9. At the same time, the support rod 12 changes the angle between it and the slider 10 through the rotation of the second rotating member 11, that is, the downward inclination angle of the support rod 12 changes accordingly. When the guide member 15 is located at the uppermost end of the adjustment groove 13, the extension of the support rod 12 is completed. At this time, the slider 10 and the sliding groove 9 can be locked through the locking mechanism (not shown in the figure). Then, the patient can be quickly transported through the rolling of the universal wheels 17. The retraction and extension process of the support rod 12 is opposite to this. The whole process has a simple principle and is easy to operate, facilitating the rapid rescue and transportation of the patient.

[0033] As Figure 1 , Figure 2 and Figure 4 shown, a rib plate 18 is arranged between the opposite sides of the two L-shaped bottom plates 7. A controller 19 is arranged above the rib plate 18. The controller 19 can adopt a controller 19 of the small controller 19PNOZmu l t i 2 model. This controller 19 is applicable to common communication networks and can also connect, control and monitor multiple components at the same time. This setting enhances the strength between the two L-shaped bottom plates 7 and also facilitates the control of the electrical components included in this medical stretcher.

[0034] As Figure 4 shown, the electric push rod 8 is electrically connected to the controller 19. This setting facilitates the control of the electric push rod 8, and thus is conducive to quickly adjusting the angle of the auxiliary plate 6.

[0035] As Figure 3 shown, a plurality of through holes 20 are respectively formed on the separated sides of the two auxiliary plates 6. This setting facilitates the handling or hoisting of the medical stretcher.

[0036] As Figure 1 , Figure 2 and Figure 3 shown, on the two sides where the two side support plates 4 are separated from each other, two gripping handles 21 are respectively provided correspondingly. This setting facilitates the handling of the medical stretcher.

[0037] As Figure 1 , Figure 2 , Figure 3 and Figure 5 shown, a hollow telescopic area 22 is correspondingly provided in the middle of the side support plate 4, and a hollow adjustment area 23 is provided on the L-shaped adjusting rod 14 corresponding to the hollow telescopic area 22. The hollow telescopic area 22 is formed by a plurality of rectangular hollow through plates sleeved in sequence according to the order of their rectangular cross-sections from large to small. The hollow adjustment area 23 is formed by a plurality of rectangular hollow pipes sleeved in sequence according to the order of their rectangular cross-sections from large to small. The structures of the hollow telescopic area 22 and the hollow adjustment area 23 are both similar to the telescopic clothes hanging rod in the prior art. This setting enables this medical stretcher to quickly adapt to the rescue and transportation of patients of different ages and different symptoms.

[0038] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 shown, the main board 3, the auxiliary board 6, the side support plate 4, the L-shaped bottom plate 7, the rib plate 18, the support rod 12 and the L-shaped adjusting rod 14 are all made of titanium 2 material. This setting makes the whole medical stretcher lighter and more able to meet the requirements of rapid rescue.

[0039] The specific operation principle is:

[0040] When using this medical stretcher, first grasp the gripping handle to carry the medical stretcher to the location of the patient. Then, pull the support rod obliquely downward so that it gradually moves obliquely downward through the guiding cooperation between the adjustment groove on it and the guiding member. The support rod drives the slider to slide in the sliding groove. At the same time, the support rod changes the angle between it and the slider through the rotation of the two rotating members, that is, the angle of the support rod tilting downward changes accordingly. When the guiding member is located at the uppermost end of the adjustment groove, the extension of the support rod is completed. At this time, the slider and the sliding groove can be locked through a locking mechanism (not shown in the figure). The retraction and extension process of the support rod is the opposite; according to the age and other conditions of the patient, adjust the two side support plates to a suitable length through the hollow telescopic area on them. At the same time, the L-shaped adjustment rod is synchronously adjusted to a suitable length through the hollow adjustment area. The adjustment lengths of the hollow telescopic area and the hollow adjustment area are equal; then, place the patient steadily on the main board according to the patient's symptoms and fix it with a fixing rope (not shown in the figure). Control the multiple electric push rods to rise (fall) simultaneously through the controller to drive the auxiliary board to rotate upward (downward) to a suitable angle through the first rotating member, so as to realize the shielding of the patient's side or the auxiliary posture maintenance for the patient who needs to lie on the side. At this time, the patient can be quickly transferred by the rolling of the universal wheels and combined with the gripping handle; when a relatively narrow elevator needs to be used during the movement process, the length of the side support plate and the L-shaped adjustment rod can be temporarily shortened to adapt to the space size of the elevator.

[0041] All the electrical components mentioned in this article can be electrically connected to the external main controller and 220V mains through a transformer. And the main controller can be a conventional known device such as a computer that plays a control role. The conventional known devices such as a computer that play a control role can receive various data signals monitored by this device in real time.

It is well known to those skilled in the art. Therefore, those skilled in the art can clearly obtain the corresponding use effects through the technical solution provided by the present invention.

[0042] The control mode of the present invention is automatically controlled by a controller. The control circuit of the controller can be realized by simple programming by those skilled in the art. The provision of power also belongs to the common knowledge in the art. And the present invention is mainly used to protect mechanical devices. Therefore, the present invention will not explain the control mode and circuit connection in detail.
