[0033] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other implementation manners obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope protected by the present invention.

[0034] Embodiment 1

[0035] Please refer to Figure 1 - Figure 10, A multifunctional stretcher for transferring critically ill patients, including a bed frame 1. On the top surface of the bed frame 1, a first side guard plate 11 and a second side guard plate 12 are installed. The first side guard plate 11 is located behind the second side guard plate 12, and a detector 7 is installed on the first side guard plate 11. It also includes an adjustable support part 3 for adjusting the height of the bed frame 1. The adjustable support part 3 includes two groups of slide rods 31. Both groups of slide rods 31 are installed on the bottom surface of the bed frame 1. Installation plates 32 are respectively slidably installed on the two groups of slide rods 31. Two guide wheels 2 are respectively installed on the two installation plates 32. Two straight legs 33 are hinged on the installation plate 32 on the left side, and two inclined legs 34 are hinged on the installation plate 32 on the right side. Shock-absorbing wheel groups 4 are respectively connected to the bottoms of the two straight legs 33 and the two inclined legs 34. Two cross bars 35 are respectively installed on the two installation plates 32. Pneumatic rods 36 are respectively hinged between the four cross bars 35 and the two straight legs 33 and the two inclined legs 34. A rotating shaft 37 is rotatably installed at the bottom of the bed frame 1 through a bracket. A first bevel gear 38 and a second bevel gear 39 are connected to the rotating shaft 37. The bottom surface of the bed frame 1 is rotatably connected to two lead screws 310. The two lead screws 310 are respectively threadedly connected to the inner walls of the two installation plates 32. When the lead screws 310 rotate, the installation plates 32 are driven to move up or down through the threaded connection. The bottom ends of the lead screws 310 are connected to third bevel gears 311. A turning handle is provided at the left end of the rotating shaft 37. The first bevel gear 38 and the second bevel gear 39 are mirror images. The first bevel gear 38 is located to the left of the second bevel gear 39. The first bevel gear 38 and the second bevel gear 39 are located between the two third bevel gears 311. When the first bevel gear 38 and the second bevel gear 39 move, they respectively mesh with the two third bevel gears 311. In the initial state, the first bevel gear 38 meshes with the third bevel gear 311 on the left side, and the second bevel gear 39 does not mesh with the third bevel gear 311 on the right side. When the first bevel gear 38 rotates, the left lead screw 310 is driven to rotate through the third bevel gear 311. When the installation plate 32 on the left side of the left side moves, the two guide wheels 2, the two straight legs 33, the two cross bars 35 and the two pneumatic rods 36 above it are driven to move synchronously. At this time, the left half of the bed frame 1 rises, pushing the rotating shaft 37 to the right, the first bevel gear 38 disengages from the third bevel gear 311 on the left side, and the second bevel gear 39 meshes with the third bevel gear 311 on the right side. By the same principle as above, by rotating the rotating shaft 37, the installation plate 32 on the right side can be controlled to rise or fall, achieving the effect of adjusting the right half of the bed frame 1. The staff can flexibly adjust the height of the bed frame 1 through the rotating shaft 37. Lifting only the left side of the bed frame 1 can make the bed frame 1 tilt to the right, lifting only the right side of the bed frame 1 can make the bed frame 1 tilt to the left, and lifting both sides of the bed frame 1 can make the bed frame 1 vertically lift. Through the setting of the adjustable support part 3, medical staff can adjust the height of the bed frame 1, achieving a multi-directional adjustment function of tilting the bed frame 1 to the left, tilting to the right, and lifting and lowering. Adjusting the tilt angle when pushing on slopes can improve the comfort of patients, and adjusting the height can meet the vehicle access requirements for vehicles of different heights.

[0036] Furthermore, the shock-absorbing wheel set 4 includes a connecting seat 41. The four connecting seats 41 are respectively connected to the bottom ends of two straight legs 33 and two inclined legs 34. The bottom of the connecting seat 41 is connected with a mounting seat 43 through two damping shock absorbers 42. A roller 44 is rotatably mounted on the inner wall of the mounting seat 43. A screw rod 45 is threadedly connected to the mounting seat 43. The bottom end of the screw rod 45 is connected with a pressing block 46. The top end of the screw rod 45 is provided with a handle. During the movement of the pressing block 46, it contacts the roller 44. By rotating the screw rod 45 through the handle, the screw rod 45 drives the pressing block 46 to move downward, so that the pressing block 46 presses against the roller 44, thereby preventing the roller 44 from rolling, which is convenient for temporarily fixing the position of the bed frame 1. Through the setting of the shock-absorbing wheel set 4, the bed frame 1 can play a shock-absorbing role when being pushed, and at the same time has a parking function.

[0037] Furthermore, the body support part 5 is used to support the patient's body. The body support part 5 includes two side air bags 51. The two side air bags 51 are both installed on the top surface of the bed frame 1. A plurality of gaskets 52 are respectively connected to the sides of the two side air bags 51 close to each other. Lower air bags 54 are respectively installed on the two straight legs 33. One ends of the two lower air bags 54 far from the straight legs 33 are respectively connected to two cross bars 35 close to the two straight legs 33. When the two straight legs 33 swing to the right, the two lower air bags 54 are squeezed through the cooperation with the two cross bars 35. Air pipes 53 are respectively connected between the two lower air bags 54 and the two side air bags 51. The two air pipes 53 both penetrate through the bed frame 1. After the two lower air bags 54 are squeezed, air is injected into the two side air bags 51 through the two air pipes 53, so that the two side air bags 51 expand. A plurality of gaskets 52 on both sides of the patient approach the patient's body and finally support both sides of the patient's body. The gaskets 52 are made of flexible materials, which improves the comfort during support. Through the setting of the body support part 5, when the patient gets on the bed frame 1, the two side air bags 51 expand, and a plurality of gaskets 52 support the patient's body, preventing the patient from moving on the bed frame 1 as the vehicle shakes, and further improving the patient's comfort.

[0038] Further, an angle adjustment part 6 is used to adjust the angle of the patient's body. The angle adjustment part 6 includes two adjustment plates 61. Installation grooves are respectively arranged on the left and right sides of the bed frame 1. The two adjustment plates 61 are respectively rotatably installed in the two installation grooves of the bed frame 1. Two hydraulic rods 62 are respectively hinged between the two adjustment plates 61 and the bottom of the bed frame 1. A grip is arranged on the adjustment plate 61, and a switch of the hydraulic rod 62 is arranged in the grip of the adjustment plate 61. By holding the grip on the adjustment plate 61 and pressing the switch of the hydraulic rod 62 at the same time, medical staff can manually adjust the angle of the adjustment plate 61. After adjustment, release the grip and the switch of the hydraulic rod 62, and the hydraulic rod 62 enters the pressure-holding state to maintain the angle of the adjustment plate 61. Medical staff can freely adjust the angles of the two adjustment plates 61; through the setting of the angle adjustment part 6, medical staff can flexibly adjust the angles of the two adjustment plates 61 to meet the required backrest angle or leg-rest angle of the patient, so as to meet the required lying posture needs of the patient.

[0039] Further, an integrated life monitoring system is arranged in the detector 7 for real-time monitoring of the patient's vital sign data. A wireless transmission module is also arranged in the detector 7 for wirelessly transmitting the patient's vital sign data to the receiving device of the medical staff, facilitating the medical staff to timely understand the patient's vital sign information; through the setting of the detector 7, the medical staff can observe the patient's vital sign information in real time and perform corresponding first aid and treatment in a timely manner.

[0040] Further, the mounting part 8 is used for mounting medical facilities. The mounting part 8 includes a support plate 81. The support plate 81 is rotatably mounted on one side of the bed frame 1 away from the first side guard plate 11 through a bracket. The right end of the second side guard plate 12 is rotatably mounted with a second plate 83 through a bracket. A first plate 82 is hinged on the second plate 83. The first plate 82 and the second plate 83 can be folded together and turned upward for storage. The support plate 81 is located below the first plate 82 and the second plate 83. The support plate 81 supports the first plate 82 and the second plate 83. The support plate 81 can be turned upward for storage. The mounting part 8 further includes a plurality of hooks 84. The plurality of hooks 84 are all mounted on the front side of the first side guard plate 11. A vertical rod 85 is rotatably mounted on the inner wall of the first side guard plate 11. One end of the vertical rod 85 away from the first side guard plate 11 is rotatably connected with a hanging rack 86. An infusion device can be suspended on the hanging rack 86. After the hanging rack 86 is rotated to be flush with the side surface of the vertical rod 85, the vertical rod 85 and the hanging rack 86 are turned over together and placed into the first side guard plate 11 to avoid the vertical rod 85 and the hanging rack 86 affecting the operation of medical staff when infusion is not required. Through the arrangement of the mounting part 8, the first plate 82 and the second plate 83 can cooperate to place accompanying medical equipment, the plurality of hooks 84 can hang some medical equipment, and the hanging rack 86 can hang an infusion device, which is convenient for placing various first-aid and medical equipment, facilitating the timely first-aid and treatment of patients. Moreover, the first plate 82 and the second plate 83, as well as the hanging rack 86 and the vertical rod 85, can be stored to avoid inconvenience when not in use.

[0041] With the above structure, the working principle of this case is as follows: A push handle is provided at the right end of the bed frame 1, and side handles are provided on both the front and rear sides of the bed frame 1, facilitating medical staff to push the bed frame 1. Taking the ambulance on the left side of the bed frame 1 as an example, the medical staff push the bed frame 1 to the left. After the two left guide wheels 2 contact the interior of the vehicle, the two straight legs 33 contact the edge of the vehicle. As the bed frame 1 continues to move to the left, the two straight legs 33 are squeezed by the edge of the vehicle and swing to the right, and the two pneumatic rods 36 contract. Subsequently, the two inclined legs 34 also contact the edge of the vehicle and swing to the right, and the two pneumatic rods 36 contract. At this time, the four guide wheels 2 support the bed frame 1 inside the vehicle. When the bed frame 1 is pulled out of the vehicle, after the inclined legs 34 and the straight legs 33 are disengaged from the vehicle, the inclined legs 34 and the straight legs 33 are reset by the resilience of the pneumatic rods 36. The two inclined legs 34 are reset first to support the bed frame 1, and then the two straight legs 33 are reset. When the bed frame 1 enters and exits the vehicle, the two straight legs 33 and the two inclined legs 34 can be automatically retracted and extended, making the transfer process of the bed frame 1 relatively stable and the operation convenient; when it is necessary to adjust the height of the bed frame 1, the rotating handle is rotated to rotate the rotating shaft 37. When the rotating shaft 37 rotates, it drives the first bevel gear 38 and the second bevel gear 39 to rotate. In the initial state, the first bevel gear 38 meshes with the third bevel gear 311 on the left, and the second bevel gear 39 does not mesh with the third bevel gear 311 on the right. When the first bevel gear 38 rotates, it drives the left screw rod 310 to rotate through the third bevel gear 311. Since the slide rod 31 limits the movement of the mounting plate 32, the mounting plate 32 can only move up and down. When the left screw rod 310 rotates, it drives the mounting plate 32 to move up or down through the threaded connection. When the left mounting plate 32 moves, it drives the two guide wheels 2, the two straight legs 33, the two cross bars 35 and the two pneumatic rods 36 above it to move synchronously. At this time, the left half of the bed frame 1 rises. When it is necessary to raise the right half of the bed frame 1, the rotating shaft 37 is pushed to the right, the first bevel gear 38 is disengaged from the third bevel gear 311 on the left, and the second bevel gear 39 meshes with the third bevel gear 311 on the right. By the same principle as above, by rotating the rotating shaft 37, the right mounting plate 32 can be controlled to rise or fall, achieving the effect of adjusting the right half of the bed frame 1. The staff can flexibly adjust the height of the bed frame 1 through the rotating shaft 37. Lifting only the left side of the bed frame 1 can make the bed frame 1 tilt to the right, lifting only the right side of the bed frame 1 can make the bed frame 1 tilt to the left, and lifting both sides of the bed frame 1 can make the bed frame 1 rise and fall vertically; through the setting of the adjustable support part 3, the medical staff can adjust the height of the bed frame 1, achieving the multi-directional adjustment function of tilting the bed frame 1 to the left, tilting to the right and rising and falling. Adjusting the tilt angle when pushing on slopes can improve the comfort of the patient, and adjusting the height can meet the vehicle access requirements for vehicles of different heights.

[0042] When the bed frame 1 moves, the vibration generated during the rolling of the rollers 44 is transmitted to the two damping shock absorbers 42 through the mounting base 43. The two damping shock absorbers 42 buffer the vibration, reducing the vibration transmitted by the connecting seat 41 to the straight legs 33 and the inclined legs 34, achieving the effect of vibration reduction. When it is necessary to fix the rollers 44, the screw 45 is rotated through the handle. The screw 45 drives the pressing block 46 to move downward, causing the pressing block 46 to press against the rollers 44, thereby preventing the rollers 44 from rolling and facilitating the temporary fixing of the position of the bed frame 1. Through the setting of the shock-absorbing wheel set 4, the bed frame 1 can play a shock-absorbing role when being pushed, and at the same time has a parking function.

[0043] When the bed frame 1 enters the vehicle, when the two straight legs 33 swing to the right, they squeeze the two lower air bags 54 through the cooperation with the two cross bars 35. After being squeezed, the two lower air bags 54 inject air into the two side air bags 51 on both sides through the two air pipes 53, causing the two side air bags 51 to expand. After the two side air bags 51 expand, the multiple gaskets 52 on both sides of the patient move closer to the patient's body and finally support both sides of the patient's body. The gaskets 52 are made of flexible materials, improving the comfort during support. Since there may be a certain amount of shaking when the bed frame 1 gets on the vehicle and when the vehicle is moving, after the multiple gaskets 52 support the patient's body, it can reduce the impact of the shaking on the patient's body and maintain the stability of the patient's body on the bed frame 1. After the two straight legs 33 are reset, the two lower air bags 54 are reset accordingly. At the same time, the two lower air bags 54 draw back the air in the two side air bags 51 into the lower air bags 54 through the air pipes 53, causing the two side air bags 51 to reset, avoiding affecting the patient getting out of bed. Through the setting of the body support part 5, when the bed frame 1 gets on the vehicle, the two side air bags 51 expand, and the multiple gaskets 52 support the patient's body, preventing the patient from moving on the bed frame 1 as the vehicle shakes, and further improving the patient's comfort.

[0044] One of the adjusting plates 61 is used to support the patient's back, and the other adjusting plate 61 is used to support the patient's legs. The medical staff holds the grips on the adjusting plates 61 and presses the switch of the hydraulic rod 62 at the same time. The medical staff can manually adjust the angle of the adjusting plates 61. After adjustment, release the grips and the switch of the hydraulic rod 62, and the hydraulic rod 62 enters the pressure-holding state to maintain the angle of the adjusting plates 61. The medical staff can freely adjust the angles of the two adjusting plates 61. Through the setting of the angle adjustment part 6, the medical staff can flexibly adjust the angles of the two adjusting plates 61 to meet the required backrest angle or leg-holding angle of the patient, so as to meet the required lying posture needs of the patient.

[0045] When the patient is being transferred, the life monitoring system of detector 7 monitors the vital sign data of the patient in real time, facilitating the observation of the patient's condition. At the same time, the vital sign data of the patient can be transmitted to the receiving device of the medical staff, enabling the medical staff to understand the vital sign information of the patient in real time. Through the setting of detector 7, the medical staff can observe the vital sign information of the patient in real time and carry out corresponding first aid and treatment in a timely manner.

[0046] The first plate 82 and the second plate 83 form a storage platform that can hold the medical equipment to be carried along, facilitating the on-the-go treatment of the patient. The first plate 82 and the second plate 83 can be folded together and flipped upward for storage. After the first plate 82, the second plate 83, and the support plate 81 are stored upward, they form an outer shape close to the first side guard plate 11 with the second side guard plate 12, enabling the staff to store the first plate 82 and the second plate 83 when passing through narrow areas or during storage, improving convenience. Multiple hooks 84 can also hang some medical equipment, and an infusion device can be hung on the hanging rack 86, facilitating the infusion of the patient during transfer. During storage, after the hanging rack 86 rotates to be flush with the side of the vertical rod 85, the vertical rod 85 and the hanging rack 86 are flipped together and placed into the first side guard plate 11 to prevent the vertical rod 85 and the hanging rack 86 from affecting the operation of the medical staff when infusion is not required. Through the setting of the mounting part 8, the first plate 82 and the second plate 83 can cooperate to hold the medical equipment to be carried along, multiple hooks 84 can hang some medical equipment, and the hanging rack 86 can hang the infusion device, facilitating the placement of various first aid and medical equipment, enabling timely first aid and treatment of the patient. Moreover, the first plate 82 and the second plate 83, as well as the hanging rack 86 and the vertical rod 85, can be stored to avoid inconvenience when not in use.
