Description

Technical Field

[0001] The present invention relates to the technical field of medical appliances, and in particular to a transport device used for critically ill patients. Background Art

[0002] At present, in the process of transporting critically ill patients, the critically ill patients are first placed on a transport stretcher, and medical staff push the transport stretcher to transport the critically ill patients to an ambulance, and then transfer them from the ambulance to a hospital. The transport stretcher has a simple structure, mainly consisting of a bed board, a bracket, rollers, etc., and has a low manufacturing cost. However, in the actual working process, the traditional transport stretcher is an integrated structure. When the transport operation is performed on a slope, the entire bed board is in an inclined state, which may cause the critically ill patients to slide from the bed board, inadvertently increasing the harm to the critically ill patients, and in the process of transportation on the slope, the traditional transport stretcher has no corresponding protective measures, and the staff needs to watch over it very carefully, which not only increases the workload of the staff, but also distracts the staff, thereby indirectly reducing the transport speed. Finally, when the transport operation is performed on the slope, when the medical staff suddenly loses strength, the traditional transport stretcher has no protective measures and may slide along the slope, causing harm to the critically ill patients. Therefore, a transport device for critically ill patients is provided. Summary of the invention

In actual use, corresponding equipment can be placed on the upper side of the eighth connecting rod 43 in the storage frame 3 for emergency use, a telescopic rod is rotatably connected to the upper side of the bracket 1, and a top plate 42 is fixedly connected to the outer side of the telescopic rod, and a plurality of hooks are fixedly installed on the lower side of the top plate 42, and the corresponding infusion bag can be hung on the hook to assist in corresponding rescue measures, a plurality of anti-slip rubber sleeves are rotatably sleeved on the outer side of the guardrail 6, and a plurality of push rods are fixedly installed on the outer side of the bracket 1, and the outer sides of the plurality of push rods are fixedly sleeved with anti-slip sleeves; like Figure 3 , Figure 4 , Figure 5 , Figure 6 First, the electric push rod 14 is a common power device, and there is a self-locking component in the electric push rod 14. When the electric push rod 14 is not started, the electric push rod 14 will be in a fixed state between the rotating cylinder 11 and the threaded rod 13 under the action of the self-locking component. Secondly, when using the present device to transport critically ill patients, if a slope is encountered, the electric push rod 14 can be started to adjust the actual distance between the electric push rod 14 and the threaded rod 13. In this process, since the rotating cylinder 11 and the threaded rod 13 are threadedly connected, the rotating cylinder 11 will rotate relative to the gantry rod 7 and the threaded rod 13, thereby completing the adjustment operation of the vertical distance between the bed board 2 and the bracket 1 at the gantry rod 7, so that there can be a suitable angle between the bed board 2 and the bracket 1. When the device moves on the slope as a whole, the bed board 2 will not be offset due to the slope, thereby effectively preventing the possibility of critically ill patients falling off the bed board 2. Fig.11 , where the dotted line represents the position of bracket 1, Fig.11 The figure in the middle upper side represents the positional relationship between the bed plate 2 and the bracket 1 when the device as a whole is traveling on a horizontal road. Fig.11 The figure on the lower middle side represents the positional relationship between the bed board 2 and the bracket 1 when the device as a whole is traveling on a sloping road surface. Compared with the figure on the upper side, it is the connection relationship between the bed board 2 and the bracket 1 after the length between the threaded rod 13 and the rotating cylinder 11 has been adjusted. After adjusting the threaded rod 13 and the rotating cylinder 11, the bed board 2 can remain in a horizontal state and will not change due to the slope. The bed board 2 will not be in an inclined state due to traveling on the slope, which will cause the critically ill patients placed on the bed board 2 to move, thereby ensuring a good transfer state. In the process of adjusting using the electric push rod 14, a corresponding detection device, such as a level detector, is fixedly installed on the lower side of the bed board 2. When adjusting the angle of the bed board 2, the staff can use the level detector as an auxiliary instrument. When it is detected that the bed board 2 is in a horizontal state, the staff needs to immediately turn off the electric push rod 14 to finally complete the adjustment of the angle of the bed board 2.

[0015] like Figure 5 , Figure 7 , Figure 8 A control assembly for controlling the movement of the guardrail 6 is installed in the control frame 26. The control assembly includes a fixed frame 5 fixedly installed on the outside of the first connecting cylinder 10 through a connecting plate. The rotating cylinder 11 rotates and penetrates the fixed frame 5. The rotating cylinder 11 is located in the fixed frame 5 and is fixedly connected to a first gear 15. Two first racks 16 are slidably connected in the fixed frame 5. The two first racks 16 are meshed with the first gear 15. The ends of the two first racks 16 away from the fixed frame 5 are fixedly connected to a slide bar 17. Two slide plates 19 are slidably connected to the lower side of the bed board 2. The side walls of the two slide plates 19 are provided with annular grooves 18. The slide bar 1 7 is slidably connected to the annular groove 18, the outer sides of the two slide plates 19 are also fixedly connected with a first connecting rod 20, a second connecting rod 22 is slidably connected in the control frame 26, the outer side of the second connecting rod 22 is rotatably connected with a third connecting cylinder 21, the first connecting rod 20 and the third connecting cylinder 21 are fixedly connected, the outer side of the second connecting rod 22 is fixedly connected with two third connecting rods 23, the two third connecting rods 23 are fixedly connected to the guardrail 6, the outer side of the second connecting rod 22 is fixedly connected with a second gear 24, the side wall of the bed board 2 is fixedly connected with a second rack 25, and the second rack 25 is meshed with the second gear ring; First, under normal circumstances, the guardrail 6 and the bed board 2 are in a vertical state. When the device moves on the slope, by starting the electric push rod 14 to adjust the actual length of the rotating cylinder 11 and the threaded rod 13, the rotating cylinder 11 will rotate, and the rotating cylinder 11 drives the first gear 15 to rotate, and the first gear 15 drives the two second racks 16 to move towards each other, and the second rack 16 drives the slide plate 19 to move towards each other through the slide bar 17, and the slide plate 19 drives the second connecting rod 22 to move towards the bed board 2 through the first connecting rod 20 and the third connecting cylinder 21, and the second connecting rod 22 drives the guardrail 6 to move towards the bed board 2 through the third connecting rod 23, shortening the distance between the guardrail 6 and the bed board 2, thereby better protecting critically ill patients, and in this process, since the second rack 25 is in a fixed state, Figure 8 Based on the direction, during the movement of the second connecting rod 22 to the right, the second connecting rod 22 will rotate in the clockwise direction, so that the guardrail 6 can further form a protective effect for critically ill patients on the bed board 2. In the above working process, the guardrails 6 on both sides of the bed board 2 move toward the direction close to the bed board 2, and the rotation direction of the guardrails 6 on both sides is also to move toward the direction close to the bed board 2, and the center of the annular groove 18 and the center of the sliding rod 17 relative to the moving track of the sliding plate 19 are in a concentric state. Fig.11 It can be known that when the actual length of the rotating cylinder 11 and the threaded rod 13 is adjusted by the electric push rod 14, the first connecting cylinder 10, the second connecting cylinder 12, the rotating cylinder 11 and the threaded rod 13 will rotate as a whole relative to the bed board 2. Since the slide plate 19 and the bed board 2 are slidably connected, after adjusting the actual length of the rotating cylinder 11 and the threaded rod 13, the slide rod 17 will slide in the annular groove 18, and in the horizontal state, the slide rod 17 is located at the bottom of the annular groove 18. Therefore, after adjusting the actual length of the rotating cylinder 11 and the threaded rod 13, the slide rod 17 will move upward relative to the slide plate 19 in the vertical direction.

[0016] like Fig. 9 , Fig.10 , Fig.12A fixed cylinder 34 is fixedly connected to the lower side of the bracket 1, a clamping frame 33 is fixedly connected to the lower side of the fixed cylinder 34, a rotating shaft 32 is rotatably installed in the clamping frame 33, the roller 4 is fixedly connected to the rotating shaft 32, a control component for preventing the roller 4 from reversing is installed in the bracket 1, the control component includes a moving frame 27 slidably installed in the bracket 1, a first spring 28 is fixedly connected between the moving frame 27 and the bracket 1, a plurality of limit plates 29 are fixedly connected to the lower side of the moving frame 27, a fourth connecting rod 30 is fixedly connected to the side wall of the plurality of limit plates 29, a fifth connecting rod 31 is fixedly connected to the side wall of the fourth connecting rod 30, a seventh connecting rod 39 is slidably connected in the fixed cylinder 34, a fixing ring 40 is fixedly connected to the outer side of the seventh connecting rod 39, and a fixing ring 40 and the fixed cylinder 34 are fixedly connected. A third spring 41 is fixedly connected between the bracket 1, a second spring 38 is fixedly connected to the lower side of the seventh connecting rod 39, a sixth connecting rod 35 is fixedly connected to the lower side of the second spring 38, a step plate 36 is fixedly connected to the lower side of the sixth connecting rod 35, a groove is opened on the outer side of the roller 4, a ratchet 37 is fixedly connected in the groove, a plurality of eighth connecting rods 43 are rotatably installed in the bracket 1, a third gear 44 is fixedly connected to the outer sides of the plurality of eighth connecting rods 43, a plurality of third racks 45 are slidably installed in the bracket 1, the plurality of third racks 45 are grouped in pairs, and each third rack 45 is meshed with the third gear 44, one of the third racks 45 in each group is fixedly connected to the seventh connecting rod 39, and another third rack 45 is fixedly connected to the fifth connecting rod 31; First, a fifth connecting rod 31, a roller 4, a third gear 44, and two third racks 45 form a group. Secondly, in the initial state, the step plate 36 will not have any effect on the rotation of the ratchet 37. Then, after adjusting the actual length of the rotating cylinder 11 and the threaded rod 13, the sliding rod 17 will move upward relative to the sliding plate 19, and the sliding rod 17 will drive the first rack 16 to move. The first rack 16 and the moving frame 27 will abut against each other and drive the moving frame 27 to move upward relative to the bed board 2. The moving frame 27 compresses the first spring 28 while driving the limit plate 29 to move upward. The limit plate 29 drives the fifth connecting rod 31 to move upward through the fourth connecting rod 30. The fifth connecting rod 31 drives the seventh connecting rod 39 to move downward through the third gear 44 and the third rack 45. The seventh connecting rod 39 compresses the third spring 41 and drives the sixth connecting rod 35 to move downward through the second spring 38. The sixth connecting rod 35 drives the step plate 36 to move downward. Fig.10 Based on the direction, the clockwise rotation of the roller 4 represents the overall movement of the device upward along the slope. During the clockwise rotation of the roller 4, the step plate 36 will not hinder the rotation of the ratchet 37, but the step plate 36 will hinder the counterclockwise rotation of the ratchet 37. Therefore, during the slope transportation process, the roller 4 can be effectively prevented from reversing, and the device will not slide along the slope as a whole after losing the restriction on the device due to various special circumstances, thereby improving the overall safety.

[0017] In the present invention, when the device is used to transfer critically ill patients, if a slope is encountered, the electric push rod 14 can be started to adjust the actual distance between the electric push rod 14 and the threaded rod 13. In this process, since the rotating cylinder 11 and the threaded rod 13 are threadedly connected, the rotating cylinder 11 will rotate relative to the gantry rod 7 and the threaded rod 13, thereby completing the adjustment operation of the vertical distance between the bed board 2 and the bracket 1 at the gantry rod 7, so that a suitable angle can be formed between the bed board 2 and the bracket 1. When the device as a whole moves on the slope, the bed board 2 will not be offset due to the slope, thereby effectively preventing the possibility of critically ill patients falling off the bed board 2, such as Fig.11 , where the dotted line represents the position of bracket 1, Fig.11 The figure in the middle upper side represents the positional relationship between the bed plate 2 and the bracket 1 when the device as a whole is traveling on a horizontal road. Fig.11 The figure on the lower middle side represents the positional relationship between the bed board 2 and the bracket 1 when the device as a whole is traveling on a sloped road surface. Compared with the figure on the upper side, it is the connection relationship between the bed board 2 and the bracket 1 after the length between the threaded rod 13 and the rotating cylinder 11 has been adjusted. After the threaded rod 13 and the rotating cylinder 11 are adjusted, the bed board 2 can still be in a horizontal state, and will not change due to the slope. The bed board 2 will not be in an inclined state due to traveling on the slope, which will cause the critically ill patients placed on the bed board 2 to move, thereby ensuring a good driving state. In the process of adjusting with the electric push rod 14, a corresponding detection device, such as a level detector, is fixedly installed on the lower side of the bed board 2. When adjusting the angle of the bed board 2, the staff can cooperate with the level detector as an auxiliary instrument. When it is detected that the bed board 2 is in a horizontal state, the staff needs to immediately turn off the electric push rod 14 to finally complete the adjustment of the angle of the bed board 2. Under normal circumstances, the guardrail 6 and the bed board 2 are in a vertical state. When the device moves on the slope, by starting the electric push rod 14 to adjust the actual length of the rotating cylinder 11 and the threaded rod 13, the rotating cylinder 11 will rotate, and the rotating cylinder 11 drives the first gear 15 to rotate, and the first gear 15 drives the two second racks 16 to move towards each other, and the second rack 16 drives the slide plate 19 to move towards each other through the slide bar 17, and the slide plate 19 drives the second connecting rod 22 to move towards the bed board 2 through the first connecting rod 20 and the third connecting cylinder 21, and the second connecting rod 22 drives the guardrail 6 to move towards the bed board 2 through the third connecting rod 23, shortening the distance between the guardrail 6 and the bed board 2, thereby better protecting critically ill patients, and in this process, since the second rack 25 is in a fixed state, Figure 8Based on the direction, during the movement of the second connecting rod 22 to the right, the second connecting rod 22 will rotate in the clockwise direction, so that the guardrail 6 can further form a protective effect for critically ill patients on the bed board 2. In the above working process, the guardrails 6 on both sides of the bed board 2 move toward the direction close to the bed board 2, and the rotation direction of the guardrails 6 on both sides is also to move toward the direction close to the bed board 2, and the center of the annular groove 18 and the center of the sliding rod 17 relative to the moving track of the sliding plate 19 are in a concentric state. Fig.11 It can be known that when the actual length of the rotating cylinder 11 and the threaded rod 13 is adjusted by the electric push rod 14, the first connecting cylinder 10, the second connecting cylinder 12, the rotating cylinder 11 and the threaded rod 13 will rotate relative to the bed board 2 as a whole. Since the slide plate 19 and the bed board 2 are in sliding connection, after the actual length of the rotating cylinder 11 and the threaded rod 13 is adjusted, the slide bar 17 will slide in the annular groove 18, and in the horizontal state, the slide bar 17 is located at the bottom of the annular groove 18. Therefore, after the actual length of the rotating cylinder 11 and the threaded rod 13 is adjusted, in the vertical direction, the slide bar 17 will move upward relative to the slide plate 19; After adjusting the actual length of the rotating cylinder 11 and the threaded rod 13, the sliding rod 17 will move upward relative to the sliding plate 19, and the sliding rod 17 will drive the first rack 16 to move. The first rack 16 and the moving frame 27 will abut against each other and drive the moving frame 27 to move upward relative to the bed board 2. The moving frame 27 compresses the first spring 28 and drives the limit plate 29 to move upward. The limit plate 29 drives the fifth connecting rod 31 to move upward through the fourth connecting rod 30. The fifth connecting rod 31 drives the seventh connecting rod 39 to move downward through the third gear 44 and the third rack 45. The seventh connecting rod 39 compresses the third spring 41 and drives the sixth connecting rod 35 to move downward through the second spring 38. The sixth connecting rod 35 drives the step plate 36 to move downward. Fig.10 Based on the direction, the clockwise rotation of the roller 4 represents that the device as a whole moves upward along the slope. During the clockwise rotation of the roller 4, the step plate 36 will not hinder the rotation of the ratchet 37, but the step plate 36 will hinder the counterclockwise rotation of the ratchet 37. Therefore, during the slope, the roller 4 can be effectively prevented from reversing, and the device as a whole will not slide along the slope after losing the restriction on the device due to various special circumstances, thereby improving the overall safety.
