Description

A transport gurney for the diagnosis and treatment of acute and critical medical conditions that facilitates patient lifting. Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a transport bed for the diagnosis and treatment of acute and critical medical conditions that facilitates patient elevation. Background Technology

[0002] A patient transport bed is a specialized medical device used for transferring patients between beds, from the operating table to the ward, and from an ambulance. The use of transport beds has solved the difficulties of moving patients from the operating table to the ward after surgery, reducing the pain and hardship caused by traditional manual patient transfers. It is an essential piece of medical equipment in hospitals.

[0003] According to patent number 202210128743.1, this invention discloses an adjustable afterloading transport bed. Through the slide rail assembly set on the bed board of the transport bed, the transport board can be moved horizontally from the transport bed to a regular hospital bed along the track, avoiding the pain of being moved during patient transfer and greatly reducing the workload of medical staff. At the same time, the existing simplified afterloading transport bed structure reduces costs, greatly improves the convenience of adjusting the position of the applicator, and shortens the afterloading treatment time.

[0004] The medical transport bed used in the aforementioned patent and existing technology for facilitating patient lifting in acute and critical medical conditions still has certain drawbacks, such as:

[0005] Existing transport gurneys for internal medicine emergency and critical care are limited in their functionality. In emergencies, medical personnel need to quickly move patients from one location to another. However, because these gurneys are fixed and difficult to lift, medical staff need to exert more force during transport, potentially increasing the difficulty of the operation, leading to increased workload, and possibly causing secondary injury to the patient during the transfer. Furthermore, in emergency situations, various first aid measures may need to be administered to the patient; if the gurney cannot facilitate on-site resuscitation, necessary interventions may be delayed.

[0006] Therefore, we propose a transport gurney for the diagnosis and treatment of acute and critical medical conditions that facilitates patient elevation, in order to address the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide a transport trolley for the diagnosis and treatment of critically ill patients in internal medicine, which facilitates patient lifting. This addresses the problem mentioned in the background art: in emergency situations, medical personnel need to quickly transfer patients from one place to another. However, existing trolleys are fixed in place, making lifting difficult. This requires more effort from medical staff during the rotation process, which may increase the difficulty of operation, increase the workload, and potentially cause secondary injury to the patient. Furthermore, during emergency treatment, various first aid measures may be required for the patient. If the trolley cannot facilitate on-site rescue, it may delay necessary interventions.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a transport gurney for the diagnosis and treatment of critically ill patients in internal medicine, comprising:

[0009] Caster base, with a mounting plate provided on top of the caster base.

[0010] Also includes:

[0011] A support rod is fixedly installed on the top of the caster base, and the support rod is symmetrically arranged about the vertical central axis of the caster base. The support rod is also symmetrically arranged about the front and back about the vertical central axis of the caster base. A telescopic rod is slidably connected inside the support rod. Rollers are slidably connected to the left and right ends of the top of the mounting plate, and the rollers are symmetrically arranged about the front and back about the vertical central axis of the mounting plate. A bed board is provided above the mounting plate, and the bottom of the bed board is rotatably connected to the top of the rollers.

[0012] The mounting bracket is fixedly installed on top of the caster base and is symmetrically arranged about the vertical central axis of the caster base. Rotating rods are rotatably connected to both ends of the mounting bracket, and a first gear is fixedly installed at the middle of each rotating rod. A worm gear is rotatably connected to the middle of the top of the mounting bracket, with its lower end extending through to the lower end of the caster base and meshing with the first gear. Lifting rods are installed on both ends of the mounting bracket, with one end fixedly connected to the rotating rod and the other end connected to a telescopic rod. Motors are fixedly installed at both the front and rear ends of the bottom of the caster base, with the motor output end fixedly connected to the lower end of the worm gear.

[0013] Preferably, the length of the telescopic rod is smaller than the length of the support rod, and the top of the telescopic rod is rotatably connected to the bottom of the mounting plate.

[0014] Preferably, the lifting rod is set at an angle, and a through groove is provided at the connection between the lifting rod and the telescopic rod. The through groove of the lifting rod is slidably connected to the telescopic rod, and the lifting rod drives the mounting plate through the telescopic rod to form a lifting structure.

[0015] Preferably, the bottom of the caster base is slidably connected to the left and right ends of the base, and the support legs are symmetrically arranged about the vertical central axis of the caster base. The upper end of the support leg extends through to the top of the caster base. A first spring is sleeved and connected to the outer side of the rod of the support leg about the top of the caster base. The top of the caster base is slidably connected to the left and right ends of the base, and guide rods are fixedly installed at the front and rear ends of the sliding plates.

[0016] Preferably, the guide rod is arranged in an inverted "L" shape, and one end of the horizontal rod of the mounting frame is inclined. The horizontal rod of the mounting frame is arranged in a corresponding position to the upper end of the support leg. The upper end of the support leg is also inclined, and the guide rod drives the support leg to form a telescopic structure.

[0017] Preferably, a second gear is rotatably connected at the middle position inside the caster base, and racks are slidably connected at both the front and rear ends inside the caster base. The rear end of the front rack in the caster base meshes with the second gear, and the front end of the rear rack in the caster base meshes with the second gear. The second gear drives the rack to slide in the opposite direction.

[0018] Preferably, the left and right ends of the caster base are slidably connected to connecting plates, and the left connecting plate of the caster base is fixedly connected to the left end of the rear rack of the caster base, and the right connecting plate of the caster base is fixedly connected to the right end of the front rack of the caster base. A tension spring is fixedly installed on the side wall of the connecting plate, and one end of the tension spring is fixedly connected to the inner side wall of the caster base. The top of the connecting plate is fixedly connected to the bottom of the sliding plate.

[0019] Preferably, a sliding block is fixedly installed at the left end of the bottom of the caster base, and the sliding block is arranged in a "U" shape. A first limiting rod is slidably connected inside the sliding block, and a second spring is sleeved and connected to the outer side of the first limiting rod about one end inside the sliding block. The upper end of the first limiting rod extends through into the interior of the caster base, and the end of the first limiting rod about one end inside the caster base is engaged with the connecting plate.

[0020] Preferably, the left and right ends of the bottom of the bed board are fixedly installed with limiting grooves, and the limiting grooves are set in a "U" shaped structure.

[0021] Preferably, the bottom of the mounting plate is slidably connected to a second limiting rod, and the upper end of the second limiting rod extends through into the interior of the limiting groove. The second limiting rod and the limiting groove are engaged, and a third spring is sleeved and connected to the outer side of the lower end of the second limiting rod.

[0022] Compared with the prior art, the beneficial effects of the present invention are: the patient transport bed for the diagnosis and treatment of internal medicine emergencies that facilitates patient lifting can better adjust its height by lifting, and can be flexibly adjusted according to different scenarios and patient needs. It also makes it easier for medical staff to transfer patients, so as to achieve faster transfer. Then, by moving horizontally, patients can be transferred quickly and effectively, thereby reducing the shaking of patients during the transfer process, reducing the risk of falls and injuries, helping to ensure patient safety, keeping patients stable during the transfer process, and at the same time, by contacting the ground for support, the movement of the bed can be reduced, providing a stable foundation and avoiding shaking during emergency rescue, thus ensuring safety during the emergency rescue process.

[0023] 1. The device is equipped with a caster base, mounting plate, support rod, telescopic rod, bed board, mounting frame, rotating rod, first gear, worm gear, lifting rod, and motor. The output end of the motor is fixedly connected to the lower end of the worm gear. The worm gear meshes with the first gear, causing the worm gear to drive the rotating rod to rotate on the mounting frame. A lifting rod is fixedly mounted on the rotating rod, with one end connected to the telescopic rod. The lifting rod's through-slot is slidably connected to the telescopic rod, and the telescopic rod is slidably connected inside the support rod. The top of the telescopic rod is rotatably connected to the bottom of the mounting plate. This allows the rotating rod to drive the telescopic rod via the lifting rod, forming a lifting structure. The telescopic rod then lifts the bed board via the mounting plate, allowing for better height adjustment to suit different scenarios and patient needs. This also facilitates easier and faster patient transfer for medical staff.

[0024] 2. The device is equipped with a mounting plate, rollers, a bed board, a limiting groove, a second limiting rod, and a third spring. The bed board is raised via a telescopic rod. Rollers are slidably connected inside the mounting plate, with the tops of the rollers rotating with the bed board. Simultaneously, pulling the second limiting rod, which is engaged with the limiting groove, causes it to slide out of the groove. This stretches the third spring, releasing the second limiting rod from its fixation to the rollers. The rollers then allow the bed board to slide within the mounting plate, enabling rapid and effective patient transfer. This reduces patient movement during transport, lowering the risk of falls and injuries, ensuring patient safety, and maintaining stability during transfer.

[0025] 3. The system includes a support leg, a first spring, a sliding plate, a guide rod, a second gear, a rack, a connecting plate, a tension spring, a sliding block, a first limiting rod, and a second spring. The first limiting rod is engaged with the connecting plate. Pulling the first limiting rod causes it to slide inside the sliding block, simultaneously stretching the first limiting rod and the second spring. This releases the first limiting rod from its fixation to the connecting plate, allowing it to be fixed to the side wall of the connecting plate via the tension spring. The connecting plate is also fixed to the rack at one end. The tension spring's force causes the connecting plate to slide inside the caster base. Simultaneously, the rack and the second gear mesh, allowing the first limiting rod to engage with the second spring. The two gears drive the connecting plates at both ends of the caster base to slide in opposite directions via the rack. Since the connecting plates and sliding plates are fixedly connected together, the sliding plates at both ends of the top of the caster base slide in opposite directions synchronously. Because the guide rod is set in an inverted "L" shape and the horizontal bar of the guide rod is set in a corresponding position with the upper end of the support leg, the guide rod drives the support leg to extend and retract, so that the support leg contacts the ground. Contact with the ground reduces the movement of the bed, provides a stable foundation, avoids shaking during emergency rescue, ensures safety during the rescue process, and avoids accidents caused by bed instability.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please refer to Figures 1-9. The present invention provides a technical solution: caster base 1, mounting plate 2, support rod 3, telescopic rod 4, roller 5, bed board 6, mounting frame 7, rotating rod 8, first gear 9, worm gear 10, lifting rod 11, motor 12, support leg 13, first spring 14, sliding plate 15, guide rod 16, second gear 17, rack 18, connecting plate 19, tension spring 20, sliding block 21, first limiting rod 22, second spring 23, limiting groove 24, second limiting rod 25, and third spring 26.

[0038] Working principle: As shown in Figures 1, 2, 3, 6, and 8, when using this medical emergency and critical care transport gurney to facilitate patient lifting, the patient is first moved from one location to another via the caster base 1. After the patient is moved to the designated position via the caster base 1, the first limiting rod 22 can be pulled. Simultaneously, the sliding block 21 is set in a "U" shape, causing the first limiting rod 22 to slide inside the sliding block 21. Then, a second spring 23 is sleeved on the outer side of the first limiting rod 22 about the inside of the sliding block 21, causing the first limiting rod 22 to slide inside the sliding block 21, which in turn drives the second spring 23. Spring 23 is stretched, and simultaneously, through the upper end of the first limiting rod 22, it extends into the interior of the caster base 1 and engages with the connecting plate 19, thereby releasing the first limiting rod 22 from fixing the connecting plate 19. Since the connecting plate 19 is slidably connected to the left and right ends inside the caster base 1, and a tension spring 20 is fixedly installed on the side wall of the connecting plate 19, one end of the tension spring 20 is also fixedly connected to the inner side wall of the caster base 1. Simultaneously, one end of the connecting plate 19 is fixedly connected to the rack 18. Therefore, the reset of the tension spring 20 causes the connecting plate 19 to slide inside the caster base 1. Because the front rack 18 and the rear rack 18 in the caster base 1 simultaneously mesh with the second gear 17, ... The elastic force of the tension spring 20, through the meshing of the second gear 17 and the rack 18, causes the connecting plate 19 to slide in the opposite direction. Since the upper end of the connecting plate 19 is fixedly connected to the bottom of the sliding plate 15, the connecting plate 19 causes the sliding plate 15 to slide on top of the caster base 1. Guide rods 16 are fixedly installed at both the front and rear ends of the top of the sliding plate 15, and the guide rods 16 are arranged in an inverted "L" shape. The horizontal rod of the guide rod 16 corresponds to the upper rod of the support leg 13. Furthermore, the sidewalls of the guide rod 16 and the support leg 13 are both inclined, allowing the horizontal rod of the guide rod 16 to slide above the upper rod of the support leg 13. The lower end of the guide rod 16 is in contact with the upper end of the support leg 13. The sliding of the sliding plate 15, via the guide rod 16, causes the support leg 13 to form a telescopic structure. Simultaneously, the support leg 13 compresses the first spring 14, causing the support leg 13 to extend and contact the ground. This contact prevents the caster base 1 from moving. After the support leg 13 contacts the ground, the fixing to the first limiting rod 22 is released, allowing the second spring 23 to reset the first limiting rod 22 and spring it into place, engaging with the connecting plate 19. The contact between the support leg 13 and the ground prevents the bed from moving, providing a stable foundation.Simultaneously, the rapid contact between the supporting leg 13 and the ground enables emergency first aid for the patient during transport, ensuring safety during the emergency treatment process;

[0039] As shown in Figures 1, 2, 5, and 7, after the caster base 1 is supported by the support leg 13, the motor 12 can be started synchronously. Since the output end of the motor 12 is fixedly connected to the lower end of the worm gear 10, the worm gear 10 rotates at the middle position of the mounting frame 7. Since the upper end of the worm gear 10 meshes with the first gears 9 on the left and right sides of the mounting frame 7, the worm gear 10 drives the rotating rod 8 to rotate on the mounting frame 7 through the first gears 9. At the same time, a lifting rod 11 is fixedly installed on the rod of the rotating rod 8, and the lifting rod 11 is set in an inclined state. Then, one end of the lifting rod 11 is connected to the telescopic rod 4, and a through groove is opened at the connection between the lifting rod 11 and the telescopic rod 4. The through groove of the lifting rod 11 is slidably connected to the telescopic rod 4. Together, the telescopic rod 4 is slidably connected to the inside of the support rod 3, and the upper end of the telescopic rod 4 is rotatably connected to the bottom of the mounting plate 2. Since the length of the telescopic rod 4 is smaller than that of the support rod 3, the lifting rod 11 drives the mounting plate 2 to form a lifting structure through the telescopic rod 4, thereby lifting the mounting plate 2 to a certain height. At the same time, the motor 12 can be started simultaneously, so that the front telescopic rod 4 or the rear telescopic rod 4 in the caster base 1 is raised or lowered inside the support rod 3, thereby tilting the mounting plate 2 to a certain angle to facilitate the transport of patients. The height can be better adjusted by lifting, and it can be flexibly adjusted according to different scenarios and patient needs to achieve faster transfer.

[0040] As shown in Figures 1, 4, and 9, when the mounting plate 2 is raised to a certain height, and when the patient is moved from the surface of the bed board 6 to the operating table or other bed, the second limiting rod 25 can be pulled. Since the upper end of the second limiting rod 25 extends through the interior of the limiting groove 24, the second limiting rod 25 is engaged with the limiting groove 24, thereby releasing the fixation of the bed board 6. At the same time, the second limiting rod 25 simultaneously drives the third spring 26 to stretch. Since the roller 5 is slidably connected inside the mounting plate 2, and the upper end of the roller 5 is rotatably connected to the bed board 6, the bed board 6 can be pushed. Thus, the roller 5 drives the bed board 6 to slide inside the mounting plate 2, thereby allowing the bed board 6 to slide and connect with other bed frames, making it convenient to transfer the patient to other bed frames.
