DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] Example 1: Please refer to Figures 1 to 5The present invention provides a technical solution: a critically ill patient transport device for medical care, comprising a base 1 and a universal wheel 11, the universal wheel 11 is mounted at the bottom of the base 1, a balancing assembly is arranged on the base 1, the balancing assembly comprises a fixed frame 2, the number of the fixed frames 2 is two, and they are respectively fixedly mounted on both sides of the upper surface of the base 1, a two-way hydraulic cylinder 21 is fixedly mounted on the inner side of the fixed frame 2, a driving block 22 is fixedly mounted on the output shaft of the two-way hydraulic cylinder 21, a guide column 23 is movably mounted inside the driving block 22, the guide column 23 is fixedly mounted on the inner side of the fixed frame 2, a first mounting frame 24 is fixedly mounted on the upper surface of the driving block 22, a push rod 25 is movably mounted on the inner side of the first mounting frame 24, a second mounting frame 26 is movably mounted on one end of the push rod 25 away from the first mounting frame 24, a connecting member 27 is fixedly mounted on the top of the second mounting frame 26, and a bed board 28 is movably mounted on one end of the connecting member 27 away from the second mounting frame 26;

[0035] A limit groove is provided on the upper surface of the bed board 28, in which a mattress 29 is clamped, a headrest 210 is provided on one side of the upper surface of the mattress 29, a handle 211 is fixedly installed on one end of the bed board 28 close to the headrest 210, and telescopic rods 212 are fixedly installed on both sides of the upper surface of the base 1, and the telescopic rods 212 are located on one side of the fixed frame 2;

[0036] The driving block 22 is provided with an anti-skid component, which is used to improve the transfer effect.

[0037] Specifically, when in use, two switch buttons respectively connected to different drive blocks 22 can be installed on both sides of the handle 211. In this way, during the transportation process, when encountering a climbing section, the patient's head will tilt downward. When climbing the slope, the drive block 22 close to the side of the headrest 210 can be started, so that the drive block 22 drives the guide column 23 to move, and the guide column 23 is used to drive the push rod 25, so that the push rod 25 drives the second installation frame 26 to rise, so that the connecting member 27 drives the end of the bed board 28 close to the headrest 210 to rise, thereby balancing the inclination of one end of the bed board 28, reducing the inclination amplitude, and preventing the patient from sliding down due to the inclination, resulting in separation from the emergency equipment, thereby making the transportation process smoother and improving the transportation effect;

[0038] When the climbing is finished, the button is started again to make the driving block 22 drive the bed board 28 to reset, so that the bed board 28 can be balanced again. The telescopic rod 212 can be used to limit the stroke of the bed board 28. In the initial state of the bed board 28, the top of the telescopic rod 212 is in contact with the bottom of the bed board 28. When the bed board 28 is reset to the maximum extent, it will contact the telescopic rod 212 again. At this time, the driving block 22 is stopped from being started again to avoid excessive reset of the bed board 28.

[0039] Similarly, when the equipment is going downhill, the end of the bed board 28 away from the headrest 210 will tilt downward. At this time, the driving block 22 away from the headrest 210 is started to make the bed board 28 rise, thereby balancing the mattress 29, achieving the purpose of preventing the patient from sliding downhill and improving the transfer effect.

[0040] Furthermore, starting the driving block 22 at the same time can make the bed board 28 rise and fall stably, making it convenient for patients to get on and off the equipment.

[0041] Example 2: Please refer to Figures 3 to 6 The anti-skid assembly includes a driving rod 3 fixedly mounted on the surface of the driving block 22, a power block 31 is fixedly mounted on one end of the driving rod 3 away from the driving block 22, a driven block 32 is movably mounted between the two power blocks 31, a slider 33 is fixedly mounted on one side of the driven block 32, a slide rail 34 is movably mounted on one end of the slider 33 away from the driven block 32, and the slide rail 34 is fixedly mounted on the upper surface of the base 1;

[0042] A connecting rod 35 is fixedly mounted on the upper surface of the driven block 32 at the side away from the headrest 210, an extension pad 36 is movably mounted on one end of the connecting rod 35 away from the driven block 32, and the extension pad 36 is movably mounted between the end away from the connecting rod 35 and the mattress 29, and a first through groove 37 adapted to the connecting rod 35 is opened inside the bed board 28;

[0043] The driven block 32 near the headrest 210 has mounting rods 38 fixedly mounted on both sides of its surface, and a cushion 39 fixedly mounted on one end of the mounting rod 38 away from the driven block 32, and a second through slot 310 adapted to the mounting rod 38 and the cushion 39 is formed inside the bed plate 28;

[0044] The shape of the power block 31 is triangular, the shape of the driven block 32 is trapezoidal, and the hypotenuse of the driven block 32 fits with the hypotenuse of the power block 31;

[0045] The shape of the slider 33 is T-shaped, the slide groove inside the slide rail 34 is a T-shaped groove, and the stroke of the slide rail 34 is greater than the stroke of the driven block 32 .

[0046] On the basis of Example 1, the tilt angle will be reduced under the action of the balancing component, but due to human operation, the tilting phenomenon may still exist. In order to ensure that the problem of patient sliding down is solved, when the device is climbing, the driving block 22 close to the side of the headrest 210 is started and drives the driving rod 3 to balance the bed board 28. At the same time, the driving rod 3 drives the power block 31 to move. The power block 31 can drive the driven block 32, so that the driven block 32 drives the installation rod 38 to rise, so that the installation rod 38 passes through the second through groove 310 and extends to the top of the bed board 28, and then the patient's shoulders are positioned to avoid the patient's sliding down during the device climbing process.

[0047] Furthermore, when the equipment goes downhill, the end of the bed board 28 away from the headrest 210 is balanced. At this time, the driven block 32 on the side away from the headrest 210 will drive the connecting rod 35 to rise, so that the connecting rod 35 drives the extension pad 36, and then the extension pad 36 flips over, positioning the patient's footsteps to prevent them from sliding down, thereby improving the transfer effect.

[0048] Example 3: Please refer to Figure 1 and Figure 7 A protective assembly is provided on the bed board 28, and the protective assembly includes an adjusting member 4, and the number of the adjusting members 4 is four, and they are symmetrically fixed at two ends on both sides of the bed board 28, and a rotating shaft 41 is movably installed in the adjusting member 4, and both sides of the outer surface of the rotating shaft 41 are provided with external threads, and a nut 42 is threadedly connected to the external thread, and the nut 42 is located on one side of the adjusting member 4;

[0049] A protective plate 43 is fixedly sleeved on the outer surface of the rotating shaft 41. The protective plate 43 is located between the two adjusting members 4. Limiting members 44 are fixedly installed on both sides of one side of the protective plate 43. The limiting members 44 are semicircular in shape. There is a distance between the two limiting members 44.

[0050] A positioning assembly is provided on the rotating shaft 41, and the positioning assembly includes a positioning member 5. There are two positioning members 5, which are fixedly mounted at both ends of the rotating shaft 41, and positioning grooves 51 adapted to the positioning members 5 are provided at the four corners of the mattress 29.

[0051] A positioning column 52 is fixedly mounted on the upper surface of the driven block 32, and positioning holes 53 corresponding to the positioning column 52 are formed inside the bed board 28 and the mattress 29;

[0052] The length of the positioning groove 51 is greater than the adjustment stroke of the adjustment member 4 , and the diameter of the positioning hole 53 is greater than the diameter of the positioning column 52 .

[0053] Based on Example 2, before the transfer, the rotating shaft 41 can be rotated so that the protective plate 43 stands upright, thereby protecting both sides of the patient and improving the safety during the transfer process;

[0054] Furthermore, when the slope section during the transfer process is long and the patient's lesion is not at the waist, the position of the rotating shaft 41 in the adjusting member 4 can be adjusted, and then the nut 42 can be tightened to position the rotating shaft 41, and the limiting member 44 can be brought close to the patient, so that the two limiting members 44 can limit the two sides of the waist respectively, further improving the limiting effect, thereby avoiding the problem of the patient sliding down during the response of the anti-slip component and the balance component;

[0055] More specifically, during the up-and-down tilting process of the equipment, if the driving stroke of the balance component is large and the process is long, and under the influence of the patient's gravity, relative displacement is likely to occur between the mattress 29 and the bed board 28, causing the patient to slide down in disguise. During the rising process of the follower block 32 on either side, the positioning column 52 on that side will be inserted into the positioning hole 53 inside the bed board 28 and the mattress 29, thereby positioning the mattress 29 to prevent it from moving relative to the bed board 28. At the same time, when the protective plate 43 is in a vertical state for protection under the rotation of the rotating shaft 41, the positioning member 5 will overlap with the positioning groove 51, further positioning the mattress 29 to ensure the stability of the mattress 29, thereby preventing the patient from sliding down in disguise.

[0056] On the one hand, when the patient's lesion is located at the waist and the limiting member 44 does not perform the limiting operation, the positioning member 5 still partially overlaps with the positioning groove 51 to achieve the positioning of the mattress 29. Figure 7 As shown in a, on the other hand, when the transfer is completed and the patient has been treated, Figure 7 As shown, by flipping the protective plate 43 one hundred and eighty degrees, the limit member 44 can be placed below the bed board 28 to form a step, which helps the patient get on and off the equipment and improves convenience. It should be noted that during production, it is necessary to provide a soft bag on the surface of the limit member 44 to reduce the load on the patient's waist.

[0057] Example 4: Please refer to Figure 1 and Figure 8 A horizontal component is provided on the handle 211, and the horizontal component includes a level ruler 6 fixedly installed on the outer surface of the handle 211, and both ends of one side of the level ruler 6 are fixedly installed with fixed plates 61, and a guide rod 62 is fixedly installed between the two fixed plates 61;

[0058] A fixed block 63 is fixedly installed in the middle of the outer surface of the guide rod 62, and telescopic springs 64 are fixedly connected to both sides of the fixed block 63, and the telescopic springs 64 are sleeved on the outer peripheral side of the guide rod 62. The end of the telescopic spring 64 away from the fixed block 63 is fixedly connected to a touch block 65, and the touch block 65 is movably installed on the outer surface of the guide rod 62, a touch switch 66 is fixedly installed on the upper surface of the fixed plate 61, and an alarm 67 is fixedly installed on the upper surface of the level 6, and the alarm 67 and the touch switch 66 are electrically connected.

[0059] On the basis of Example 1, the balance component can be controlled according to the horizontal display of the level ruler 6, which can more conveniently compare the balance of the mattress 29, ensure that the patient approaches a balanced state, and improve the transfer effect;

[0060] Furthermore, during the first aid process, the medical staff's work is complicated and tight, and they are prone to forget to start the balance component during transportation. When the balance component is not started, when the equipment goes up and down the slope, the trigger block 65 will stretch the telescopic spring 64 under the influence of gravity, and move on the surface of the guide rod 62, and then contact the trigger switch 66, and start the alarm 67 to sound an alarm, reminding the medical staff to start the balance component, making the transportation process smoother.

[0061] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
