Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and in particular to a device for transporting critically ill patients. Background Art

[0002] Critically ill patients refer to patients whose illness develops suddenly, their condition is serious and changes rapidly. Critically ill patients include those with severe trauma, major surgery and those whose vital signs must be continuously and closely monitored and supported; those who need cardiopulmonary resuscitation; those with organ failure or multiple organ failure; those with severe shock, sepsis and poisoning, and those who are critically ill due to physical or chemical factors. In the Department of Neurology, transfer devices are needed to temporarily move patients from the beds in the ward to the department for treatment.

[0003] During actual use, when some critically ill patient transfer devices in the prior art encounter bumps or depressions on the ground, although the use of springs can reduce part of the impact force so that the critically ill patient transfer device will not vibrate significantly, due to the usage limitations of the springs themselves, the critically ill patient transfer device will still produce multiple small-amplitude bumps due to the released potential energy of the springs, which brings a bad user experience to the critically ill patients. In severe cases, it may also cause secondary cracking of the wounds of the critically ill patients, posing a danger to the critically ill patients. Therefore, a critically ill patient transfer device is needed. Utility Model Content

[0014] Preferably, a plurality of balls are rollingly embedded on the periphery of the slide bar, and the ends of the balls are in rolling contact with the inner wall of the arc-shaped slide groove.

[0015] The present application also provides another critically ill patient transport device, comprising:

[0016] A connecting rod is fixed on one side of the mounting block, and an elastic damping member is installed at the lower end of the connecting rod. The elastic damping member includes an arc sleeve rod and a movable rod;

[0017] The upper end of the arc sleeve rod is fixed to the lower end of the connecting rod, and the lower end of the arc sleeve rod forms a single opening.

[0020] In summary, the technical effects and advantages of the utility model are:

[0021] 1. In the utility model, through the arrangement of the support rod and the compression spring, in the process of pushing the transfer bed to move, when encountering a protrusion on the ground, the forward direction of the roller first contacts the protrusion, and the protrusion squeezes the roller, and then the roller produces a backward deflection tendency under the squeezing effect of the protrusion and the gravity of the transfer bed itself, so that the roller drives the support rod to deflect, at this time, the support rod rotates along the rotation connection between it and the mounting block, so that the compression spring is compressed, and finally the roller produces a backward and upward deflection movement along the surface of the protrusion, thereby converting the original force that tends to lift the mounting block into the deflection force of the roller, so that the transfer bed can basically remain horizontal when passing the protrusion;

[0022] In addition, when there is a depression on the ground, a gap is generated at the front end of the roller, which will cause the roller to be temporarily free from the restriction of the ground and the gravity pressure of the transfer bed. At this time, the support rod is deflected to the side of the forward direction of the transfer bed under the action of the compression spring, so that the roller moves forward and downward, so that the position of the roller can be relatively lowered and move in line with the bottom of the depression, and the transfer bed can also be kept basically horizontal when passing through the depression;

[0023] The critically ill patient transfer device can ensure that it is not prone to up and down bumps when encountering protrusions or depressions, providing a good user experience for critically ill patients, while avoiding possible injuries to critically ill patients caused by bumps caused by protrusions or depressions during transfer, greatly improving the use effect and safety of critically ill patients during transfer.

[0024] 2. In the utility model, by setting a reset torsion spring, when the support rod is deflected, a torque in the opposite direction can be generated, thereby damping the deflection of the support rod, thereby avoiding repeated deflection of the support rod during movement, and prompting the roller to stably deflect and reset when encountering protrusions or depressions, so that the transfer bed can be more stable during movement, further improving the use effect of the critically ill patient transfer device.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] Example 1

[0036] refer to Figure 1-5 A critically ill patient transport device shown includes a transport bed 1, a support leg 11 is provided at the lower end of the transport bed 1, a roller 2 is installed at the lower end of the support leg 11, and an equipment expansion frame 12 is fixed to one side of the transport bed 1;

[0037] The lower end of the support leg 11 is rotatably connected to a mounting block 3 via a bearing, and the mounting block 3 rotates along the axis of the support leg 11;

[0038] Support rods 4 are rotatably connected to both sides of the mounting block 3, and the lower ends of the two support rods 4 are rotatably connected to the two ends of the rotating shaft of the roller 2 respectively;

[0039] There is a gap between the upper end of the roller 2 and the lower end of the mounting block 3;

[0040] Arc-shaped slide grooves 31 are provided on both sides of the mounting block 3 , and compression springs 5 ​​are fixed to one end of the two arc-shaped slide grooves 31 , and the other ends of the two compression springs 5 ​​are fixed to the middle parts of the two support rods 4 through two connecting pieces.

[0041] Based on the above structure, in the process of pushing the transfer bed 1 to move, when encountering a situation where there is a protrusion on the ground (such as a protrusion caused by debris, thresholds, etc.) (refer to the attached Figure 5), the forward direction of the roller 2 first contacts the protrusion, and the protrusion squeezes the roller 2. Then, the roller 2 has a tendency to deflect backwards under the squeezing effect of the protrusion and the gravity of the transfer bed 1 itself, so that the roller 2 drives the support rod 4 to deflect. At this time, the support rod 4 rotates along the rotation connection between it and the mounting block 3, so that the compression spring 5 is compressed, and finally the roller 2 deflects backwards and upwards along the surface of the protrusion, thereby converting the force that originally tends to lift the mounting block 3 into a deflection force of the roller 2, so that the transfer bed 1 remains basically horizontal when passing the protrusion;

[0042] In addition, when there is a depression on the ground, a gap is generated at the front end of the roller 2, which will cause the roller 2 to be temporarily free from the restriction of the ground and the gravity pressure of the transfer bed 1. At this time, the support rod 4 is deflected to the side of the forward direction of the transfer bed 1 under the action of the compression spring 5, so that the roller 2 moves forward and downward, so that the position of the roller 2 can be relatively lowered and move in line with the bottom of the depression, and the transfer bed 1 can also be kept basically horizontal when passing through the depression;

[0043] From the above, it can be seen that the critically ill patient transfer device can ensure that the critically ill patient transfer device is not prone to up and down bumps when encountering protrusions or depressions, providing a good use experience for critically ill patients, while avoiding possible injuries to critically ill patients caused by bumps caused by protrusions or depressions during transfer, greatly improving the use effect and safety of critically ill patients during transfer.

[0044] Furthermore, the upper ends of the two support rods 4 are fixed by support shafts 42, and the support shafts 42 rotate and penetrate the two sides of the mounting block 3;

[0045] A sliding rod 41 is fixed to one side of the two support rods 4 that are close to each other. One side of the two sliding rods 41 is fixed to one end of two compression springs 5 ​​respectively. The two sliding rods 41 are movably connected in the arc-shaped sliding groove 31 .

[0046] Furthermore, mounting grooves 32 are provided on both sides of the mounting block 3, and the support shaft 42 is located in the mounting grooves 32;

[0047] A return torsion spring 6 is fixed in each of the two installation grooves 32 , and the other ends of the two return torsion springs 6 are respectively fixed to the side walls of the two support rods 4 on the sides close to each other.

[0048] By setting the reset torsion spring 6, a torque in the opposite direction can be generated when the support rod 4 is deflected, thereby damping the deflection of the support rod 4, thereby avoiding repeated deflection of the support rod 4 during movement, and prompting the roller 2 to stably deflect and reset when encountering protrusions or depressions, so that the transfer bed 1 can be more stable during movement, further improving the use effect of the critically ill patient transfer device.

[0049] Furthermore, a plurality of balls 7 are rollingly embedded on the periphery of the slide rod 41 , and ends of the balls 7 are in rolling contact with the inner wall of the arc-shaped slide groove 31 .

[0050] By setting the ball 7, rolling contact is formed between the slide rod 41 and the inner wall of the slide groove 31, thereby greatly reducing the friction between the inner wall of the slide groove 31 and the slide rod 41, reducing the wear of the slide rod 41 and the slide groove 31, and at the same time ensuring that the slide rod 41 can slide stably in the slide groove 31 to achieve a stable deflection effect.

[0051] Example 2

[0052] refer to Figure 6-7 Another critically ill patient transport device shown is different from that in Example 1 in that:

[0053] A connecting rod 33 is fixed to one side of the mounting block 3, and an elastic damping member 8 is installed at the lower end of the connecting rod 33. The elastic damping member 8 includes an arc-shaped sleeve rod 81 and a movable rod 82;

[0054] The upper end of the arc sleeve rod 81 is fixed to the lower end of the connecting rod 33, and the lower end of the arc sleeve rod 81 forms a single opening. One end of the movable rod 82 is slidably connected to the arc sleeve rod 81 and the other end extends out of the lower end opening of the arc sleeve rod 81. The movable rod 82 forms a seal with the arc sleeve rod 81, and the other end of the movable rod 82 is fixed to the support rod 4 through the sliding rod 41;

[0055] One end of the movable rod 82 away from the support rod 4 is elastically connected to the inner top wall of the arc-shaped sleeve rod 81 through the compression spring 5;

[0056] Several sealing rings 9 are fixed on the inner side of the opening of the arc sleeve rod 81. The inner walls of the several sealing rings 9 are interference fit with the side walls of the movable rod 82. The sliding sealing connection between the arc sleeve rod 81 and the movable rod 82 is achieved through the sealing rings 9, and the sealing rings 9 themselves can also provide a certain damping effect to further improve stability.

[0057] By setting the elastic damping member 8, in the process of pushing the transfer bed 1 to move, when encountering a protrusion or depression on the ground, the compression spring 5 will be forced to contract or stretched without force, so that the support rod 4 and the roller 2 will produce corresponding deflection, and it can also achieve the effect of ensuring that the critically ill patient transfer device is not prone to up and down bumps when encountering protrusions or depressions, providing a good use experience for critically ill patients, while avoiding the possible damage to critically ill patients caused by bumps caused by protrusions or depressions during the transfer process, greatly improving the use effect and safety of critically ill patients during transfer;

[0058] At the same time, since the arc sleeve rod 81 and the movable rod 82 are connected in a sliding seal by the sealing ring 9, when the movable rod 82 moves into the arc sleeve rod 81 or moves out of the arc sleeve rod 81, the movable rod 82 will squeeze the air inside the arc sleeve rod 81 or expand the air inside the arc sleeve rod 81, so that high pressure or negative pressure is generated between the end of the movable rod 82 and one end of the arc sleeve rod 81, which can also play a damping role, thereby making the critically ill patient transport device more stable during movement and less prone to repeated shaking.

[0059] It should be further explained that the user can choose to use embodiment 1 or embodiment 2 or a combination of the two according to actual use requirements to achieve better use purposes in response to different situations.

[0060] Working principle of the utility model: in daily use, when the transport bed 1 is pushed to move, when encountering a protrusion on the ground, the forward direction of the roller 2 first contacts the protrusion, and the protrusion squeezes the roller 2. Then, the roller 2 has a tendency to deflect backwards under the squeezing effect of the protrusion and the gravity of the transport bed 1 itself, so that the roller 2 drives the support rod 4 to deflect. At this time, the support rod 4 rotates along the rotation connection between it and the mounting block 3, so that the compression spring 5 is compressed, and finally the roller 2 deflects backwards and upwards along the surface of the protrusion, thereby converting the force that originally tends to lift the mounting block 3 into a deflection force of the roller 2, so that the transport bed 1 remains basically horizontal when passing the protrusion.

[0061] In addition, when there is a depression on the ground, a gap is generated at the front end of the roller 2, which will cause the roller 2 to be temporarily free from the restriction of the ground and the gravity pressure of the transfer bed 1. At this time, the support rod 4 is deflected to the side of the forward direction of the transfer bed 1 under the action of the compression spring 5, so that the roller 2 moves forward and downward, so that the position of the roller 2 can be relatively lowered and move in line with the bottom of the depression, and the transfer bed 1 can also be kept basically horizontal when passing through the depression;

[0062] At the same time, by setting the reset torsion spring 6, when the support rod 4 is deflected, a torsion force in the opposite direction can be generated, thereby playing a damping role in the deflection of the support rod 4, thereby avoiding the support rod 4 from repeatedly deflecting during the movement, and prompting the roller 2 to stably deflect and reset when encountering a protrusion or depression, so that the transfer bed 1 can be more stable during the movement, further improving the use effect of the critically ill patient transfer device;

[0063] The critically ill patient transfer device can ensure that it is not prone to up and down bumps when encountering protrusions or depressions, providing a good user experience for critically ill patients, while avoiding possible injuries to critically ill patients caused by bumps caused by protrusions or depressions during transfer, greatly improving the use effect and safety of critically ill patients during transfer.

[0064] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
