Description

Technical Field

[0001] The present invention relates to the technical field of emergency critically ill patient transport, in particular to an emergency critically ill patient transport device. Background Art

[0002] Medical transport refers to the process of transferring patients from one location to another for further treatment or placement in the healthcare field. This includes moving patients from dangerous areas to safe areas, and from areas with limited medical resources to resource-rich medical institutions. Transport equipment primarily includes transport beds and stretchers. Transport equipment is primarily used in hospital emergency departments, operating rooms, ICUs, wards, and other locations. It can improve the efficiency of patient transport, reduce the workload of medical staff, minimize nursing risks, and ensure patient safety. Furthermore, these devices also play a vital role in disaster relief, urban emergencies, and transferring patients to hospitals.

[0003] Patient transfer devices are usually used to move seriously ill patients. Such patients usually have the characteristic of being unable to move normally. During the transfer process, the patient needs to be moved from the bed to the transfer device. At this time, since the patient cannot move independently, medical staff need to carry the patient to the transfer device. When the patient is light in weight, the medical staff is still able to move the patient. When the patient is heavy in weight, it becomes very laborious for the medical staff to move the patient. Moreover, when a seriously ill patient needs emergency treatment, the patient needs to be moved to the operating room quickly. At this time, during the movement process, the transfer device needs to be pushed quickly. Since there are many people in the hospital, when the transfer device is pushed quickly and an emergency occurs in front, the transfer device needs to be urgently braked. At this time, the patient lying on the transfer device will move or even fall, which can easily cause secondary injuries to the patient. Summary of the Invention

[0023] More specifically, in this embodiment, when using the device, the bed board 5 is aligned with the patient's bed, and then the handle 47 is turned to drive the rotating rod 48 to rotate. The rotation of the rotating rod 48 further rotates the gear ring 49, thereby driving the straight tooth row 59 to move, so that the bed board 5 moves and approaches the patient's back. As the bed board 5 moves, the patient is finally shoveled onto the bed board 5. Then, the handle 47 is turned in the opposite direction to cause the gear ring 49 to rotate in the opposite direction, and the bed board 5 is retracted onto the keel frame 25 to load the patient. The setting of this loading component realizes the transfer and loading of the patient by using the bed board 5 to shovel up the patient, saving manpower and material resources. In addition, when transporting the patient, the patient's movement range is very small, and it is not easy to cause secondary harm to the patient, further improving the practicality of this critically ill patient transfer device.

[0024] It is worth noting that, in this embodiment, a loading assembly is provided on the surface of the bottom plate 9, and the height adjustment assembly includes: Connecting frame 13, adjusting rod 27 and right-angle curved rod 14, the end face of connecting frame 13 is fixedly connected to the inner wall of frame 1, the upper end surface of connecting frame 13 is hinged to the end face of right-angle curved rod 14, the end surface of adjusting rod 27 is rotatably connected to the end surface of right-angle curved rod 14, the surface of adjusting rod 27 is slidably connected to sliding frame 12, the upper surface of sliding frame 12 is slidably connected to the lower end face of base plate 9, the lower end face of sliding frame 12 is also provided with a through threaded groove, the groove wall of the threaded groove is threadedly connected to threaded rod 10, the surface of threaded rod 10 is rotatably connected to fixed plate three 11, the upper end face of fixed plate three 11 is fixedly connected to the lower end face of base plate 9, the end face of threaded rod 10 is also fixedly connected to handle two 8.

[0025] More specifically, in this embodiment, rotating the second handle 8 drives the first threaded rod 10, thereby driving the first sliding frame 12 to slide under the bottom plate 9, further causing the adjustment rod 27 to slide within the first sliding frame 12, thereby causing the right-angled curved rod 14 to rotate about the right-angle end as the axis, thereby further adjusting the height of the bottom plate 9; The setting of this height adjustment component, by adjusting the height of the base plate 9, further enables the critically ill patient transfer device to transport patients in beds of different heights, thereby further improving the practicality of the critically ill patient transfer device.

[0027] More specifically, in this embodiment, when the handle 1 47 is rotated, the rotating rod 1 48 is rotated, which further rotates the sleeve 1 51, which in turn drives the limiting post 1 52 to slide in the track groove 50. In combination with the limiting rod 2 54, the limiting post 1 52 can be moved back and forth left and right. Then, through the sliding groove 1 56 on the bed board 5, the bed board 5 is further driven to move slightly left and right when it moves toward the patient's back. The setting of the left and right translation assembly utilizes the slight left and right movement of the bed board 5 when moving toward the patient's back, thereby further reducing the resistance of the bed board 5 entering under the patient's back, making the entry of the bed board 5 smoother, and also further reducing the damage to the patient when the bed board 5 is inserted under the patient's back.

[0028] Example 3, based on the above example: See also Figures 1 to 13 In this embodiment, the inflatable component includes: The airbag 3, the connecting pipe 29, the connecting column 60, the one-way valve 35, the two-way valve 32 and the ventilation pipe 30, the upper end surface of the bed plate 5 is provided with a notch, the groove wall of the notch is fixedly connected to the surface of the airbag 3, and the side of the bed plate 5 is also provided with a mounting hole that passes through the notch, the hole wall of the mounting hole is fixedly connected to the outer surface of the connecting pipe 29, one end of the connecting pipe 29 is fixedly connected to the surface of the airbag 3, and the other end of the airbag 3 is fixedly connected to the surface of the ventilation pipe 30, the end face of the connecting column 60 is fixedly connected to the end face of the push column 55 away from the sliding groove 56, the surface of the connecting column 60 is hinged with a curved rod 38, the curved rod A piston plate 39 is hingedly connected to one end of a valve 38 away from a connecting column 60, and the surface of the piston plate 39 is slidingly connected to the piston cylinder 36. The outer surface of the piston cylinder 36 is fixedly connected to a mounting frame 37, and the surface of the mounting frame 37 is fixedly connected to the surface of the keel frame 25. The outlet end of the one-way valve 35 is fixedly connected to the bottom end face of the piston cylinder 36, the inlet end of the one-way valve 35 is fixedly connected to the air intake pipe 34, the outlet end of the two-way valve 32 is fixedly connected to the end face of the piston cylinder 36, the outlet end of the two-way valve 32 is fixedly connected to a hose 33, and the end of the hose 33 away from the two-way valve 32 is fixedly connected to the surface of the ventilation pipe 30.

[0029] More specifically, in this embodiment, when the limiting post 52 moves left and right, it simultaneously drives the connecting post 60 to move left and right. The left and right movement of the connecting post 60 drives the crank rod 38 to deflect at an angle, further pulling the piston plate 39 to move back and forth in the piston cylinder 36. This, in conjunction with the one-way flow of the one-way valve 35 and the two-way flow of the two-way valve 32, allows gas to be rushed into the airbag 3 through the hose 33, pushing up the airbag 3. Then, the gas in the airbag 3 is sucked into the piston cylinder 36, causing the airbag 3 to deflate. The setting of this inflatable component makes the airbag 3 continuously push up and deflate, so that when the airbag 3 is pushed up, it slightly pushes up the patient's back, increasing the gap between the patient's back and the bed, so that the bed board 5 can more easily enter under the patient's back. The airbag 3 is also continuously pushed up and deflated to simulate massaging the patient's back, thereby relaxing the patient's back muscles. Further, when the bed board 5 is placed under the patient's back, it squeezes the patient's muscles and causes injury to the patient.

The clamping block 22 is then released, and the clamping block 22, under the action of the telescopic restoration rod 21, causes the trapezoidal block 24 to clamp the clamping frame 20, further preventing the third curved rod 19 from restoring, thereby achieving the purpose of raising the armrest 4. The setting of this anti-fall component can make it easier to take protective measures for the patient by quickly raising the armrest 4, and it is also easier to lower the armrest 4, which is convenient for carrying the patient, and further improves the practicality of this critically ill patient transport device.

[0031] Example 5, based on the above example: See also Figures 1 to 13 In this embodiment, the tilting assembly includes: The second curved rod 31, the baffle frame 46 and the pad 28, one end of the second curved rod 31 is hinged to the side of the bottom plate 9, the end of the second curved rod 31 away from the bottom plate 9 is hinged to the pulling plate 1 45, the upper end surface of the pad 28 is fixedly connected to the lower end surface of the keel frame 25, the lower end surface of the pad 28 is in contact with the upper end surface of the bottom plate 9, the inner wall of the baffle frame 46 is slidably connected to the surface of the pulling plate 1 45, the lower end surface of the baffle frame 46 is fixedly connected to the connecting plate 1 44, and the surface of the connecting plate 1 44 is fixed.

The surface of the connecting plate 1 44 is also fixedly connected to a handle 3 6. More specifically, in this embodiment: in the process of using the handle 3 6 to push the critically ill patient transport device to move, when an emergency occurs on the moving path, it is necessary to slow down the critically ill patient transport device, and further the medical staff will pull the handle 3 6. Then, since the critically ill patient transport device needs to slow down during movement, the critically ill patient transport device will generate a certain inertia, thereby causing a relative displacement between the handle 3 6 and the base plate 9, so that the handle 3 6 drives the connecting plate 1 44 to move, so that the baffle frame 46 moves, and at the same time, the spring 1 42 is stretched, and the baffle frame 46 moves, which drives the pulling plate 1 45 to slide in the baffle frame 46, thereby further driving the curved rod 2 31 to deflect at an angle, so that the keel frame 25 deflects slightly about the end connected to the base plate 9 as the axis, so that the patient changes from lying horizontally to lying at an inclined angle, thereby offsetting the displacement of the patient caused by inertia, further reducing the risk of the patient falling during transportation, and avoiding the patient from suffering secondary injury; The setting of this tilting component causes relative displacement between the handle 3 6 and the base plate 9 during deceleration, thereby causing the keel frame 25 to slightly deflect around the end connected to the base plate 9 as the axis, so that the patient can lie at an inclined angle instead of lying horizontally, thereby offsetting the displacement caused to the patient by inertia, further reducing the risk of the patient falling during transportation, and avoiding secondary injuries to the patient.

[0032] Working principle: When using this emergency critical patient transport device, the following steps are involved: By turning the handle 2 8 to drive the threaded rod 10, the height of the bottom plate 9 is adjusted so that the bed plate 5 is aligned with the height of the bed where the patient is located. By turning the handle 1 47 to drive the rotating rod 1 48 to rotate, the bed plate 5 moves and approaches the patient's back. The rotating rod 1 48 further rotates the kit 1 51, and the limiting rod 2 54 can realize the reciprocating left and right lateral movement of the limiting column 1 52, further driving the bed plate 5 to move slightly left and right when moving toward the patient's back, and at the same time driving the connecting column 1 60 to move left and right. , pull the piston piece 39 to move back and forth in the piston cylinder 36, and rush the gas into the airbag 3 through the hose 133 to push the airbag 3 up, and then suck the gas in the airbag 3 into the piston cylinder 36, so that the airbag 3 is deflated. After shoveling the patient onto the bed board 5, turn the handle 147 in the opposite direction to make the gear ring 149 rotate in the opposite direction, and retract the bed board 5 onto the keel frame 25. Then, pinch the armrest 4 and the clamping block 22, pull the armrest 4 upward, so that the curved rod 19 is in a state perpendicular to the fixing frame 17, and then release it. The clamping block 22 is opened, so that the clamping block 22, under the action of the telescopic recovery rod 21, causes the trapezoidal block 24 to clamp the clamping frame 20, further preventing the curved rod 3 19 from recovering, thereby achieving the purpose of raising the armrest 4 to protect the patient. Then, the handle 3 6 is used to push the critically ill patient transport device to move. When an emergency occurs on the moving path, it is necessary to slow down the critically ill patient transport device, so that a relative displacement occurs between the handle 3 6 and the base plate 9, so that the handle 3 6 drives the connecting plate 1 44 to move, so that the baffle frame 46 moves, and at the same time, the spring 1 42 is stretched, and the baffle frame 46 moves, which drives the pulling plate 1 45 to slide in the baffle frame 46, thereby further driving the curved rod 2 31 to deflect at an angle, so that the keel frame 25 deflects slightly with the end connected to the base plate 9 as the axis, further causing the patient to lie at an inclined angle instead of lying horizontally, thereby offsetting the displacement brought to the patient by inertia, further reducing the risk of the patient falling during the transportation process, and avoiding the patient from suffering secondary injury.
