Description

Technical Field

[0001] This utility model relates to the field of medical rescue equipment technology, and in particular to a rapid transport device for critically ill patients. Background Technology

[0002] Medical rescue equipment is crucial for the rapid transport of critically ill patients, saving precious time and ensuring their safety. However, existing methods of transporting critically ill patients have significant limitations. Traditional methods mostly rely on ordinary stretchers combined with manual carrying or simple transport trolleys, which are extremely slow. Within hospitals, when critically ill patients need to be quickly transferred from the emergency department to the operating room or intensive care unit, narrow passageways, crowded conditions, and the poor mobility of ordinary transport equipment often result in lengthy transport times, preventing patients from receiving timely and critical treatment, severely impacting treatment outcomes and the patient's chances of survival. In disaster sites, such as earthquakes, fires, and traffic accidents, damaged roads and complex terrain make it difficult for traditional transport equipment to pass quickly, greatly hindering the efficient implementation of rescue work and increasing the risk to patients' lives. Existing transport devices have some shortcomings, such as poor shock absorption when traversing uneven ground, which can easily cause the bed to shake and sway, increasing the patient's pain and potentially causing secondary injuries; the height adjustment of the bed is not flexible enough and cannot adapt well to different transport scenarios, such as the height difference between the ambulance and the hospital bed; and the protective measures to prevent patients from falling during transport are not perfect, failing to simultaneously ensure convenience and safety, and therefore need to be improved. Utility Model Content

[0003] The purpose of this invention is to address the problems in existing technologies, such as poor shock absorption leading to bed shaking, insufficient bed height adjustment, inability to adapt well to different transport scenarios, and inadequate protective measures to prevent patients from falling during transport. Therefore, this invention proposes a rapid transport device for critically ill patients.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a rapid transport device for critically ill patients, comprising a base and a bed body. The lower surface of the bed body is provided with casters, and an mounting sleeve is fixedly installed on the surface of the casters. A connecting rod is slidably connected inside the mounting sleeve, and a limit block is fixedly installed at one end of the connecting rod. A tension spring is provided inside the mounting sleeve. A connecting plate is fixedly installed on the lower surface of the bed body. A hydraulic cylinder is fixedly installed on the surface of the base, and a limit rod A is fixedly installed on the surface of the base. A side panel is slidably connected to the inner side of the bed body, and a cross plate is fixedly installed on the side of the side panel. A motor is fixedly installed on the lower surface of the bed body, and a limit rod B is fixedly installed on the lower surface of the bed body. A threaded rod is rotatably connected inside the bed body.

[0005] Preferably, one end of the connecting rod is fixedly connected to the lower surface of the base, and the limiting block is slidably connected to the mounting sleeve.

[0006] Preferably, one end of the tension spring is fixedly connected to the side of the limiting block, and the other end of the tension spring is fixedly connected to the inside of the mounting sleeve.

[0007] Preferably, the output end of the hydraulic cylinder is fixedly connected to the side of the connecting plate, and the connecting plate is slidably connected to the limiting rod A.

[0008] Preferably, the side of the guardrail is provided with a rubber buffer strip, and the rubber buffer strip is made of natural rubber.

[0009] Preferably, the output end of the motor is fixedly connected to one end of the threaded rod, and the threaded rod is threadedly connected to the cross plate.

[0010] Preferably, the horizontal plate and the limiting rod B are slidably connected.

[0011] Preferably, a fixing block is slidably connected to the side of the bed, an infusion stand is fixedly installed on the surface of the fixing block, a protrusion is fixedly connected to the side of the fixing block, a pull rod is slidably connected inside the fixing block, a limit plate is fixedly installed on the surface of the pull rod, a tension spring is sleeved on the surface of the pull rod, and a limit hole is opened on the side of the bed.

[0013] Preferably, one end of the tension spring is fixedly connected to the side of the limiting plate, and the other end of the tension spring is fixedly connected to the side of the fixing block.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, by setting a universal wheel connection structure with tension springs under the bed, when the transfer device passes over uneven ground, the tension springs can use their elasticity to buffer the vibration, effectively reducing the degree of bed shaking and lowering the risk of injury to the patient caused by excessive shaking. At the same time, the hydraulic cylinder on the base can drive the bed to rise and fall, making it convenient for medical staff to adjust the bed height according to actual needs. In addition, the motor drives the threaded rod to rotate, causing the horizontal plate that is threadedly connected to the threaded rod and slidably connected to the limit rod B to drive the guardrail to slide inside the bed, thereby achieving the blocking of both sides of the bed and preventing the patient from falling due to shaking during the transfer, ensuring the patient's safety. The natural rubber buffer strips on the side of the guardrail can further protect the patient from collision injuries.

[0016] 2. In this utility model, the IV stand on the side of the bed is slidably connected to the bed through a fixing block. Utilizing a convenient fixing mechanism composed of a protrusion, a pull rod, a limiting plate, and a tension spring, medical staff can easily move the position of the IV stand as needed, facilitating intravenous infusion treatment for patients. It can also be quickly fixed to ensure the stability of the infusion process. While meeting the patient's treatment needs, it does not affect the transport efficiency due to the inconvenience of operating the IV stand. Overall, it improves the safety, comfort, and convenience of transporting critically ill patients, providing strong support for emergency work. Attached Figure Description

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1: As Figures 1-5 As shown, this utility model provides a technical solution: a rapid transport device for critically ill patients, including a base 1 and a bed 2. The lower surface of the bed 2 is provided with casters 3, and a mounting sleeve 4 is fixedly installed on the surface of the casters 3. A connecting rod 5 is slidably connected inside the mounting sleeve 4, and a limit block 6 is fixedly installed at one end of the connecting rod 5. A tension spring 7 is provided inside the mounting sleeve 4. A connecting plate 8 is fixedly installed on the lower surface of the bed 2. A hydraulic cylinder 9 is fixedly installed on the surface of the base 1, and a limit rod A10 is fixedly installed on the surface of the base 1. A side panel 11 is slidably connected to the inner side of the bed 2, and a cross plate 13 is fixedly installed on the side of the side panel 11. A motor 14 is fixedly installed on the lower surface of the bed 2. There is a limit rod B15. The bed body 2 is internally rotatably connected to a threaded rod 16. One end of the connecting rod 5 is fixedly connected to the lower surface of the base 1. The limit block 6 is slidably connected to the mounting sleeve 4. One end of the tension spring 7 is fixedly connected to the side of the limit block 6. The other end of the tension spring 7 is fixedly connected to the inner side of the mounting sleeve 4. The output end of the hydraulic cylinder 9 is fixedly connected to the side of the connecting plate 8. The connecting plate 8 is slidably connected to the limit rod A10. The side of the guardrail 11 is provided with a rubber buffer strip 12. The rubber buffer strip 12 is made of natural rubber. The output end of the motor 14 is fixedly connected to one end of the threaded rod 16. The threaded rod 16 is threadedly connected to the cross plate 13. The cross plate 13 is slidably connected to the limit rod B15.

[0026] In this embodiment, if the height of the bed 2 needs to be adjusted, the hydraulic cylinder 9 on the base 1 is first activated. The output end of the hydraulic cylinder 9 pushes the connecting plate 8 connected to it, thereby raising or lowering the bed 2 to a suitable height. At the same time, the connecting plate 8 slides on the surface of the limiting rod A10, making the bed 2 more stable when rising or falling, so as to connect with other medical equipment or adapt to different transport scenarios. Next, when it is necessary to provide protective barriers on both sides of the bed 2, the motor 14 on the lower surface of the bed 2 is activated. The motor 14 drives the threaded rod 16 connected to its output end to rotate. Since the threaded rod 16 is threadedly connected to the horizontal plate 13, and the horizontal plate 13 is slidably connected to the limiting rod B15, the horizontal plate 13 drives the guardrail 11 to move. The stable upward movement allows the horizontal plate 13 to move horizontally and stably on the lower surface of the bed 2, thereby driving the railing 11, which is fixedly connected to it, to slide upward on the inner side of the bed 2. The natural rubber buffer strip 12 on the side of the railing 11 can not only avoid collision injury to the patient, but also enhance the protective effect and prevent the patient from falling off the bed due to shaking during the transfer. During the transfer, the universal wheels 3 under the bed 2 are connected to the base 1 through the connecting rod 5 inside the mounting sleeve 4 on its surface. The limiting block 6 at one end of the connecting rod 5 slides inside the mounting sleeve 4. When encountering uneven ground and causing bumps, the tension spring 7 inside the mounting sleeve 4 will use its elastic deformation to buffer the vibration, reduce the shaking amplitude of the bed 2, and provide relatively stable transfer conditions for the patient.

[0027] Example 2: Figures 1-5 As shown, a fixing block 17 is slidably connected to the side of the bed body 2. An infusion stand 18 is fixedly installed on the surface of the fixing block 17. A protrusion 19 is fixedly connected to the side of the fixing block 17. A pull rod 20 is slidably connected inside the fixing block 17. A limit plate 21 is fixedly installed on the surface of the pull rod 20. A tension spring 22 is sleeved on the surface of the pull rod 20. A limit hole 23 is opened on the side of the bed body 2. The protrusion 19 is slidably connected to the bed body 2. The pull rod 20 is slidably connected to the limit hole 23. One end of the tension spring 22 is fixedly connected to the side of the limit plate 21. The other end of the tension spring 22 is fixedly connected to the side of the fixing block 17.

[0028] In this embodiment, if it is necessary to adjust the position of the IV stand 18 on the side of the bed 2, pull the pull rod 20 on the side of the fixing block 17. This causes the limiting plate 21 on the surface of the pull rod 20 to compress the tension spring 22 sleeved on the pull rod 20. At the same time, the pull rod 20 disengages from the limiting hole 23 on the side of the bed 2. At this time, the fixing block 17 can slide on the side of the bed 2 through the protrusion 19 on its side. After moving the IV stand 18 to the appropriate position, release the pull rod 20. Under the action of the tension spring 22, the pull rod 20 re-inserts into the limiting hole 23, thereby fixing the IV stand 18. This facilitates IV infusion treatment for the patient and ensures the safety of the patient and the smooth progress of the treatment throughout the entire transport process.

[0029] The working principle of this embodiment is as follows: In use, the patient is first placed on the bed 2. If the height of the bed 2 needs to be adjusted, the hydraulic cylinder 9 on the base 1 is activated. The output end of the hydraulic cylinder 9 pushes the connecting plate 8 connected to it, causing the bed 2 to rise or fall to a suitable height. Simultaneously, the connecting plate 8 slides on the surface of the limiting rod A10, making the bed 2 more stable during rise or fall, thus facilitating connection with other medical equipment or adaptation to different transport scenarios. Next, when it is necessary to provide protective barriers on both sides of the bed 2, the motor 14 on the lower surface of the bed 2 is activated. The motor 14 drives the threaded rod 16 connected to its output end to rotate. Since the threaded rod 16 is threadedly connected to the horizontal plate 13, and the horizontal plate 13 is slidably connected to the limiting rod B15, the horizontal plate 13 drives the guardrail 11 to rise stably, allowing the horizontal plate 13 to move stably laterally on the lower surface of the bed 2. This, in turn, causes the guardrail 11, which is fixedly connected to it, to slide and rise inside the bed 2. The natural rubber buffer strip 12 on the side of the guardrail 11 not only prevents collision injuries to the patient but also enhances the protective effect. To prevent patients from falling off the bed during transport due to shaking, the casters 3 under the bed 2 are connected to the base 1 via connecting rods 5 inside the mounting sleeve 4. A limiting block 6 at one end of the connecting rod 5 slides within the mounting sleeve 4. When encountering uneven ground, the tension spring 7 inside the mounting sleeve 4 uses its elastic deformation to buffer the vibration, reducing the shaking amplitude of the bed 2 and providing relatively stable transport conditions for the patient. If it is necessary to adjust the position of the IV stand 18 on the side of the bed 2, pull the pull rod 20 on the side of the fixing block 17. The limiting plate 21 on the surface of the pull rod 20 compresses the tension spring 22 sleeved on the pull rod 20. At the same time, the pull rod 20 disengages from the limiting hole 23 on the side of the bed 2. At this time, the fixing block 17 can slide on the side of the bed 2 through the protrusion 19 on its side. After moving the IV stand 18 to the appropriate position, the pull rod 20 is released. Under the action of the tension spring 22, the pull rod 20 is reinserted into the limiting hole 23, thereby fixing the IV stand 18, which facilitates the infusion treatment of the patient and ensures the safety of the patient and the smooth progress of the treatment during the entire transportation process.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
