Description

Technical Field

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

[0002] The symptoms of critically ill patients develop suddenly, are serious, and change rapidly. The slightest carelessness often leads to irreparable consequences. When critically ill patients become ill, they generally need to be quickly transferred to the hospital emergency room for rescue, and then transferred to the relevant department or intensive care unit after the rescue is completed.

[0003] Critically ill patients often find it difficult to move independently, and some of them may fall directly to the ground when they become ill. Multiple medical staff are required to lift the patients onto a transport device for transportation, which is time-consuming and labor-intensive and can easily delay the patient's condition. In addition, the patient's body needs to be pulled or turned over during the lifting process. Since critically ill patients themselves are in poor physical condition, these actions may cause secondary injuries to the patients if they are not careful. Summary of the invention

[0004] The purpose of the present invention is to overcome the problems in the prior art and to provide a critically ill patient care transfer device that can quickly and smoothly move the patient to the transfer device.

[0005] The present invention provides a device for transporting patients with acute and critical illnesses, comprising:

[0006] The transport frame comprises a connecting arm and two supporting arms, one end of each of the supporting arms is connected to the two ends of the connecting arm to form a U shape, and a walking assembly is provided at the bottom of each of the two supporting arms, so that the transport frame can be quickly moved to the patient's location;

[0007] Two lifting platforms are respectively arranged on a supporting arm, and a lifting assembly is connected between each lifting platform and the corresponding supporting arm so that the two lifting platforms can be lifted and lowered synchronously;

[0008] Four straight-moving wheels are respectively rotated at the front and rear ends of the bottoms of the two lifting platforms, and when the lifting platforms are at the lowest position, each straight-moving wheel is grounded, and the walking assembly is suspended in the air. In this way, when the transfer frame is moved toward the patient, since the straight-moving wheels are grounded, the transfer frame can be prevented from being deviated when moving toward the patient;

[0009] The conveyor belt mechanism includes two transmission rollers, a conveyor belt wound around the transmission rollers and a driving assembly for driving the transmission rollers to rotate. The two ends of each transmission roller are rotatably connected to the bottom of a lifting platform. The two transmission rollers are respectively located at the front end and the rear end of the bottom of the lifting platform. In this way, in the process of moving the transfer frame, the patient can be smoothly transported to the conveyor belt through the transmission belt. Since the position of the conveyor belt is relatively low, the patient will not move or move drastically, and medical staff do not need to expend too much physical strength in the process of transporting the patient.

[0010] Preferably, a transmission assembly is provided between both ends of each transmission roller and the nearest straight-moving wheel, and the transmission assembly includes a first gear and a second gear meshing with each other, the first gear is coaxially fixedly connected to the corresponding transmission roller, the second gear is coaxially fixedly connected to the corresponding straight-moving wheel, and the ratio of the diameter of the transmission roller to the pitch circle diameter of the first gear is equal to the ratio of the diameter of the straight-moving wheel to the pitch circle diameter of the second gear. In this way, in the process of moving the patient onto the conveyor belt, the patient can be kept stationary or only moved very slightly relative to the ground, thereby ensuring that the patient will not move or move significantly in the process of being moved onto the conveyor belt, and ensuring to the greatest extent possible that the patient will not suffer secondary injury during the transportation process.

[0011] Preferably, the two straight-running wheels on the same lifting platform are arranged along the same straight line, and the left and right sides of the bed are respectively detachably connected with a supporting guide rail, and the top surfaces of the supporting guide rails are provided with guide grooves arranged along the long sides of the bed, and the spacing between the two guide grooves is adapted to the spacing between the straight-running wheels on different lifting platforms, so that the straight-running wheels on the same lifting platform can roll along the same guide groove. In this way, the lifting platform can be moved out of the bed while the patient can be left on the bed, and when the patient is transferred to the bed, there will be no large-scale activity or movement.

[0012] Preferably, the connecting arm is a telescopic rod, and the sides of the two lifting platforms that are away from each other are connected with a slide in a horizontal sliding direction, and the sliding direction is parallel to the connecting arm. The lifting components correspond to each slide one by one, and the lifting components are connected between the corresponding slides and the support arm to make the slides rise and fall synchronously. In this way, when moving and walking is required, the connecting arm is adjusted to the shortest state, which can reduce the width of the present invention and facilitate the movement and transportation of patients in narrower or complex scenarios.

[0013] Preferably, each of the slides and lifting platforms is connected with a stabilizing spring, and the stabilizing spring is parallel to the connecting arm. In this way, it is possible to prevent the lifting platform from sliding when the length of the connecting arm increases, thereby reducing the stability of the transfer and stabilizing the lifting platform.

[0014] Preferably, the two straight wheels on the same lifting platform are arranged along the same straight line, and a supporting rail is respectively provided on the left and right sides of the bed. The two supporting rails are respectively slidably connected to a clamping member along the horizontal direction, and the two clamping members are respectively clamped on the left and right sides of the bed. The top surfaces of the supporting rails are provided with guide grooves arranged along the long sides of the bed. In this way, the present invention can transfer patients to beds of different widths.

[0015] Preferably, there are two slides connected to each lifting platform, and each slide is located at the front end and the rear end of the corresponding lifting platform, respectively, and the lifting components include:

[0016] A guide column is vertically arranged, wherein the bottom end of the guide column is fixedly connected to the corresponding support arm, and the top end of the guide column passes through the corresponding slide and is slidably connected to the corresponding slide;

[0017] The screw rod is vertically arranged, the bottom end of the screw rod is rotatably connected to the corresponding support arm, the top end of the screw rod passes through the corresponding slide and is threadedly connected to the corresponding slide, and the top end of the screw rod is also rotatably connected to the top end of the guide column;

[0018] The first motor is fixedly connected to the support arm or the guide column, the output shaft of the first motor is coaxially fixedly connected to the screw rod, the first motor is electrically connected to the power supply, and is also connected to the controller signal, so that the synchronization of the first motors can be ensured, and the lifting platform can be driven to rise and fall smoothly, reducing the possibility of secondary injury to the patient.

[0019] Preferably, a plurality of auxiliary support rollers are evenly arranged between the two transmission rollers, each auxiliary support roller is parallel to the transmission roller, and both ends of each auxiliary support roller are rotatably connected to the bottom of a lifting platform, so that each auxiliary support roller can help the conveyor belt to support the patient without affecting the transmission of the conveyor belt.

[0020] Preferably, the diameter of each of the auxiliary support rollers is equal to the diameter of the transmission roller, so that when the patient is conveyed to the conveyor belt, the patient will not be moved up and down, thereby affecting the patient's comfort.

[0021] Preferably, the outer wall of each of the auxiliary support rollers is made of elastic material, so that the patient's comfort on the conveyor belt can be improved and injuries from hard objects can be avoided.

[0022] Compared with the prior art, the present invention has the following advantages:

[0023] The critically ill patient nursing and transporting device of the present invention can be provided with a transport frame, two lifting platforms, four straight-moving wheels and a conveyor belt mechanism. Through the walking assembly connected to the bottom of the support arm of the transport frame, the present invention can be quickly moved to the position where the patient is located, and the U-shaped opening of the transport frame is directed toward the patient. At this time, the lifting assembly is started to lower the lifting platform to the lowest position, so that each straight-moving wheel is grounded, the walking assembly is suspended, and the conveyor belt of the conveyor belt mechanism is also located at a lower position, and then the transport frame is moved toward the patient. Since the straight-moving wheels are grounded, the transfer frame can be prevented from being offset when moving toward the patient.

[0024] After the transfer frame moves to the patient's side, the patient's head or feet are placed on the conveyor belt of the conveyor mechanism first, and then the driving component is started to make the transmission roller drive the transmission belt to rotate. In the process of moving the transfer frame, the patient can be smoothly transported to the conveyor belt by driving the transmission belt. Since the position of the conveyor belt is relatively low, the patient will not move or move drastically, and medical staff do not need to expend too much physical energy in the process of transporting the patient.

[0040] The following is combined with Figure 1-13 , the specific implementation of the present invention is described in detail, but it should be understood that the protection scope of the present invention is not limited by the specific implementation. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0041] The critically ill patient care transfer device provided by the present invention comprises a transfer frame, two lifting platforms 2, four straight wheels 8 and a conveyor belt mechanism. The transfer frame comprises a connecting arm 11 and two supporting arms 12. One end of the two supporting arms 12 is respectively connected to the two ends of the connecting arm 11 to form a U shape. A walking assembly is provided at the bottom of the two supporting arms 12. Specifically, in the present embodiment, the walking assembly comprises four brakeable universal wheels 7. Each universal wheel 7 is respectively located at the front end and the rear end of the bottom of a supporting arm 12, wherein one end close to the connecting arm 11 is the rear end, and the other end is the front end, so as to conveniently realize the walking of the present invention in all directions and facilitate braking to ensure the stability of the present invention when the position needs to be fixed. The two lifting platforms 2 are respectively arranged on a supporting arm 12, and a lifting assembly is connected between each lifting platform 2 and the corresponding supporting arm 12, so that the two lifting platforms 2 can be lifted and lowered synchronously. The four straight-running wheels 8 are rotatably arranged at the front and rear ends of the bottoms of the two lifting platforms 2, respectively, wherein one end close to the connecting arm 11 is the rear end and the other end is the front end, and when the lifting platform 2 is at the lowest position, each straight-running wheel 8 is grounded, and each of the universal wheels 7 is suspended in the air. The conveyor belt mechanism includes two transmission rollers 31, a conveyor belt 32 wound around the transmission rollers 31, and a driving component for driving the transmission rollers 31 to rotate. Specifically, the conveyor belt 32 is a synchronous conveyor belt, and the driving component includes a second motor 34. In order to better realize the driving of the transmission roller 31, in this embodiment, both ends of each transmission roller 31 are coaxially fixedly connected to the output shaft of a second motor 34, and the second motor 34 is electrically connected to the power supply and connected to the controller signal. The two ends of each transmission roller 31 are rotatably connected to the bottom of a lifting platform 2, and the two transmission rollers 31 are respectively located at the front and rear ends of the bottom of the lifting platform 2.

[0042] Directions:

[0043] Initially, the transfer frame is supported and moved by the universal wheels 7 connected to the bottom of the support arm 12. When the patient needs to be lifted, the transfer frame is pushed to the patient's position, and the U-shaped opening of the transfer frame is directed toward the patient. Then, the lifting assembly is started to lower the lifting platform 2 to the lowest position, so that each straight wheel 8 is grounded, each universal wheel 7 is suspended, and at this time, the conveyor belt 32 of the conveyor belt mechanism is also located at a lower position, specifically, 1 cm to 2 cm off the ground, and then the transfer frame is moved toward the patient. Since the straight wheels 8 are grounded, the transfer frame can be prevented from deviating when moving toward the patient.

[0044] After the transfer frame is moved to the patient's side, the patient's head or feet are first placed on the conveyor belt 32 of the conveyor belt mechanism, and then the driving component is started to make the transmission roller 31 drive the transmission belt 32 to rotate. In the process of moving the transfer frame, the patient can be smoothly transported to the conveyor belt 32 by driving the transmission belt 32. Since the position of the conveyor belt 32 is relatively low and close to the ground, the patient will not move or move drastically. At the same time, medical staff do not need to expend too much physical strength in the process of transporting the patient. After that, the lifting platform 2 is raised by the lifting component. In this way, the patient can be quickly and smoothly moved to the transmission belt 32 and transferred.

[0045] As a preferred embodiment, a transmission assembly is provided between both ends of each transmission roller 31 and the nearest straight-running wheel 8, and the transmission assembly includes a first gear 41 and a second gear 42 meshing with each other, the first gear 41 is coaxially fixedly connected to the corresponding transmission roller 31, and the second gear 42 is coaxially fixedly connected to the corresponding straight-running wheel 8, and the ratio of the diameter of the transmission roller 31 to the pitch circle diameter of the first gear 41 is equal to the ratio of the diameter of the straight-running wheel 8 to the pitch circle diameter of the second gear 42. By adopting the above technical solution, the driving assembly can simultaneously drive the transmission roller 31 and the straight-running wheel 8 to rotate, and by The ratio of the diameter of the transmission roller 31 to the pitch circle diameter of the first gear 41 is equal to the ratio of the diameter of the linear wheel 8 to the pitch circle diameter of the second gear 42. Therefore, the speed at which the transmission roller 31 drives the conveyor belt 32 to convey is consistent with the speed at which the linear wheel 8 moves. Therefore, in the process of moving the patient onto the conveyor belt 32, the patient can be kept stationary relative to the ground or only has very small movement due to slipping, etc., thereby ensuring that the patient will not move or move significantly in the process of being moved onto the conveyor belt 32, and ensuring to the greatest extent possible that the patient will not suffer secondary injury during the transportation process.

[0046] As a preferred embodiment, the two straight wheels 8 on the same lifting platform 2 are arranged along the same straight line, and the left and right sides of the bed are respectively detachably connected with a support rail 5, and the top surface of the support rail 5 is provided with a guide groove 51 arranged along the long side of the bed, and the spacing between the two guide grooves 51 is adapted to the spacing between the straight wheels 8 on different lifting platforms 2, so that the straight wheels 8 on the same lifting platform 2 roll along the same guide groove 51. When the patient is transferred to the bed, the two support rails 5 are installed on both sides of the bed, the lifting platform 2 is first moved to a position higher than the bed, and the U-shaped opening of the transfer frame is opened. The opening is directed toward the bed, and the transfer frame is pushed to move the lifting platform 2 and the conveyor belt 32 to the top of the bed. The two support arms 12 are respectively located on both sides of the bed. Then, the lifting platform 2 is lowered until the straight-moving wheel 8 is mortgaged in the guide groove 51, and the driving component is started to drive the transmission roller 31 and the straight-moving wheel 8 to rotate, so that the straight-moving wheel 8 rolls along the guide groove 51 to the outside of the bed, and the transmission roller 31 rotates in the opposite direction. In this way, the lifting platform 2 can be moved out of the bed while the patient is left on the bed, and the height difference between the conveyor belt 32 and the bed is also low, so that when the patient is transferred to the bed, there will be no large-scale activity or movement.

[0047] As a preferred embodiment, the connecting arm 11 is a telescopic rod. Specifically, the connecting arm 11 can be one of an electric telescopic rod, a hydraulic telescopic rod or a pneumatic telescopic rod. The two sides of the lifting platforms 2 that are away from each other are both connected with a slide 21 in a horizontal sliding direction, and the sliding direction is parallel to the connecting arm 11. The lifting component corresponds to each slide 21 one by one, and the lifting component is connected between the corresponding slides 21 and the support arm 12 so that each slide 21 can be lifted and lowered synchronously, so that the slide 21 can adaptively slide on the corresponding lifting platform 2 while the connecting arm 11 is extended and retracted. By adopting the above technical solution, when the movement and walking process is required, the connecting arm 11 is adjusted to the shortest state, which can reduce the width of the present invention and facilitate the movement and transportation of patients in narrower or complex scenarios. When the patient needs to be moved to the bed, the connecting arm 11 is extended so that the two support arms 12 can be located on both sides of the bed respectively, and the lifting platform 2 and the conveyor belt 32 are moved to directly above the bed.

[0048] As a preferred embodiment, each of the slides 21 and the lifting platform 2 is connected with a stabilizing spring 22, and the stabilizing spring 22 is parallel to the connecting arm 11. By adopting the above technical solution, when the connecting arm 11 is extended and retracted, the sliding distance of the slide 21 on the corresponding lifting platform 2 can be consistent, so that the position of the conveyor belt 32 between the two lifting platforms 2 can be aligned. At the same time, it can prevent the lifting platform 2 from sliding when the length of the connecting arm 11 increases, resulting in reduced stability of transportation, thereby stabilizing the lifting platform 2.

[0049] As a preferred embodiment, the two straight wheels 8 on the same lifting platform 2 are arranged along the same straight line, and a support rail 5 is respectively provided on the left and right sides of the hospital bed. The two support rails 5 are respectively slidably connected to a clamping member in the horizontal direction, and two slide bars 52 are connected to the side of the two support rails 5 away from each other. Each clamping member includes two clamping bodies 53, and a slide groove 531 and a clamping groove 532 are provided on one side of each clamping body 53. The slide groove 531 is located above the clamping groove 532. Each clamping body 53 corresponds to a slide bar 52 one by one, and each slide bar 52 is slidably connected to a corresponding slide groove 531 in a horizontal direction, and the sliding direction is perpendicular to the long side of the bed. A first fixing bolt 54 is passed through the top of the clamping body 53, and the bottom end of the first fixing bolt 54 can be inserted into the slide groove 531 and abut against the slide bar 52. The first fixing bolt 54 is threadedly connected to the clamping body 53, and the width of the clamping groove 532 is adapted to the thickness of the left and right edges of the bed, so that the left and right sides of the bed can be adjusted. The side edge can enter the clamping groove 532, and a second fixing bolt 55 is passed through the bottom of the clamping body 53. The bottom end of the second fixing bolt 55 can be inserted into the clamping groove 532 and rest against the bed. The second fixing bolt 55 is threadedly connected to the clamping body 53. The top surface of the support guide rail 5 is provided with a guide groove 51 arranged along the long side of the bed. Each clamping body 53 is fixed to the bed through the clamping groove 532 and the two fixing bolts 55. Each support guide rail 5 slides in the slide groove 531 through the slide rod 52, and the horizontal position of each support guide rail 5 on the corresponding clamping body 53 can be adjusted, and fixed by the first fixing bolt 54. In this way, the support guide rail 5 can be used on beds of different widths. By adjusting the horizontal position of each support guide rail 5 on the corresponding clamping body 53, the distance between the guide grooves 51 on the two support guide rails 5 can be adapted to the distance between the straight wheels on the two lifting platforms 2, so that the present invention can transfer patients to beds of different widths.

[0050] As a preferred embodiment, the slides 21 connected to each of the lifting platforms 2 include two, and each of the slides 21 is respectively located at the front end and the rear end of the corresponding lifting platform 2, and the lifting components include a guide column 61, a screw rod 62 and a first motor 63. The guide column 61 is vertically arranged, and the bottom end of the guide column 61 is fixedly connected to the corresponding support arm 12, and the top end passes through the corresponding slide 21 and is slidably connected to the corresponding slide 21. The screw rod 62 is vertically arranged, and the bottom end of the screw rod 62 is rotatably connected to the corresponding support arm 12, and the top end passes through the corresponding slide 21 and is threadedly connected to the corresponding slide 21. The top end of the screw rod 62 is also rotatably connected to the top end of the guide column 61. The first motor 63 is dynamically connected, and is fixedly connected to the support arm 12 or the guide column 61. The output shaft of the first motor 63 is coaxially fixedly connected to the screw rod 62. The first motor 63 is electrically connected to the power supply and is also connected to the controller signal. By adopting the above technical solution, each first motor 63 is connected to the controller signal, which can ensure the synchronization of each first motor 63, and the lifting platform 61 can be guided by the guide column 61, and each lifting platform 2 can be supported by each screw rod 62. The screw rod 62 is driven to rotate by the first motor 63, and the lifting platform 2 can be driven to rise and fall smoothly without large vibration, thereby reducing the possibility of secondary injury to the patient.

[0051] As a preferred embodiment, a plurality of auxiliary support rollers 33 are evenly arranged between the two transmission rollers 31, each auxiliary support roller 33 is parallel to the transmission roller 31, and both ends of each auxiliary support roller 33 are rotatably connected to the bottom of a lifting platform 2, and the surface of each auxiliary support roller 33 is provided with teeth adapted to the synchronous teeth of the conveyor belt 32. By adopting the above technical solution, each auxiliary support roller 33 can help the conveyor belt 32 to support the patient without affecting the transmission of the conveyor belt 32.

[0052] As a preferred embodiment, the diameter of each auxiliary support roller 33 is equal to the diameter of the transmission roller 31. By adopting the above technical solution, when the patient is conveyed to the conveyor belt 32, the patient's height will not fluctuate, thereby affecting the patient's comfort.

[0053] As a preferred embodiment, the outer wall of each auxiliary support roller 33 is made of elastic material. The above technical solution can improve the comfort of the patient on the conveyor belt 32 and avoid injuries caused by hard objects.
