Description

Technical Field

[0001] The invention belongs to the technical field of medical equipment and relates to a special patient transport device. Background Art

[0002] Critically ill patients usually refer to those who are seriously ill and require close monitoring and active treatment measures. These patients may face life-threatening conditions and need to be treated in intensive care units or similar facilities so that medical staff can monitor their vital signs and physiological functions in real time. During treatment, critically ill patients are usually transported within or between hospitals because their conditions are serious and they cannot walk on their own.

[0003] At present, when critically ill patients are transferred within or between hospitals, in order to avoid the impact of ups and downs on patients during the transfer process, straps are usually set on the transfer device, and the patients are restrained to the transfer device with the straps to ensure the stability of the patient's body during the transfer.

[0004] However, due to the acceleration and deceleration during the uphill and downhill process, the body of the critically ill patient may easily slide, resulting in greater local pressure exerted by the straps on the body of the critically ill patient, causing local skin or subcutaneous tissue damage under the continuous pressure of the critically ill patient, increasing the risk of pressure sores. Summary of the invention

[0005] The purpose of the present invention is to provide a special patient transfer device, which can prevent the body of a critically ill patient from sliding for a long time during going up and down slopes, thereby avoiding local skin or subcutaneous tissue damage to the body of a critically ill patient under continuous pressure, and reducing the risk of pressure sores.

[0041] like Figure 1 , Figure 2As shown, the present invention provides a patient-specific transport device, including a bed body 1, a cylinder body 8, a first counterweight ball 9, a disc 7, a rotating assembly, a transmission assembly and an elastic lifting assembly. The bed body 1 is a box structure, and the upper part of the bed body 1 is an open structure. A bed board 2 is horizontally arranged near the upper opening in the bed body 1, and both sides of the bed board 2 are rotatably connected to the inner wall of the bed body 1 near the middle, that is, a rotating shaft 6 is horizontally arranged in the bed body 1, and the position of the rotating shaft 6 is close to the middle position of the bed board 2, and the two ends of the rotating shaft 6 are rotatably connected to the inner wall of the bed body 1. The rotating shaft 6 passes through the middle position of the side of the bed board 2 and is fixedly connected to the bed board 2, so that the bed board 2 can swing up and down around the rotating shaft 6. A strap is arranged on the upper part of the bed board 2, so that the patient can be fixed on the bed board 2 by the strap. The lower part of the bed board 2 is respectively provided with elastic support components near its two ends. The elastic support components are used to elastically support the two ends of the bed board 2 to prevent the bed board 2 from swinging significantly around the rotating shaft 6. The cylinder 8 is arranged inside the bed body 1, and the lower part of the cylinder 8 is rotatably connected to the bottom of the bed body 1, so that the cylinder 8 can rotate freely. The first counterweight The ball 9 is movably arranged in the cylinder 8, the disc 7 is horizontally arranged between the bed board 2 and the cylinder 8, the disc 7 and the first counterweight ball 9 are connected by a connecting shaft 19, and the connecting shaft 19 is hinged to the upper part of the cylinder 8, so that the connecting shaft 19 can swing around the hinge at the upper part of the cylinder 8. The rotating assembly is connected to the cylinder 8, and the rotating assembly is used to drive the cylinder 8 to rotate. The transmission assembly is respectively connected to the cylinder 8 and the disc 7, and the transmission assembly is used to make the disc 7 swing and drive the disc 7 to rotate through the cylinder 8, thereby driving the first counterweight ball 9 to rotate, so that the first counterweight ball 9 has a gyro effect, which is convenient for resetting the rotating disc 7. The elastic lifting component is arranged on the disc 7. The elastic lifting component is used to provide an upward force for the bed board 2 as the disc 7 rotates after the disc 7 is reset, so that the bed board 2 can return to a horizontal state, and the bed board 2 is actively adjusted, so that the critically ill patient can return to a horizontal state along with the bed board 2, thereby preventing the body of the critically ill patient from being affected by sliding for a long time, thereby avoiding local skin or subcutaneous tissue damage to the body of the critically ill patient under the action of continuous pressure, and reducing the risk of pressure sores.

[0042] like Figure 1 , Figure 2 As shown, a base 4 is provided at the lower part of the bed 1, and a support column 3 is vertically provided between the bed 1 and the base 4. Both ends of the support column 3 are respectively connected to the bed 1 and the base 4. The support column 3 is an electric telescopic structure, which is convenient for adjusting the height of the bed 1. Universal wheels 5 are respectively provided at the lower part of the base 4 near its four corners, which is convenient for the bed 1 to move with the base 4 to transport critically ill patients.

[0043] like Figure 2 , Figure 3As shown, the transmission assembly includes two transmission rods 21 and two guide grooves 20. The two transmission rods 21 are vertically symmetrically arranged on both sides of the connecting shaft 19. The lower end of each transmission rod 21 is fixedly connected to the upper part of the cylinder 8. The two guide grooves 20 are opened on the disc 7. The positions of the two guide grooves 20 correspond to the two transmission rods 21 one by one. The two guide grooves 20 are on the same diameter of the disc 7. The upper end of each transmission rod 21 passes through the corresponding guide groove 20 and is located above the disc 7. There is a gap between the upper end of each transmission rod 21 and the disc 7. Through the cooperation of the two transmission rods 21 and the two guide grooves 20, while the two transmission rods 21 drive the disc 7 to rotate, the two transmission rods 21 can swing left and right in the two guide grooves 20, so that the disc 7 can swing left and right, and then the first counterweight ball 9 is reset from the tilted state during the rotation.

[0044] like Figure 2 As shown, the rotating assembly includes a motor 27, which is arranged at a position near the cylinder 8 at the lower part of the bed 1. The output end of the motor 27 passes through the lower part of the bed 1 and is connected to the cylinder 8. The motor 27 is electrically connected to the controller 46, so that the start and stop of the motor 27 can be controlled by the controller 46. The motor 27 is located at the center of the annular liquid storage cavity 29, and a driving cavity 26 is opened near the upper end of the support column 3. The motor 27 is fixedly arranged in the driving cavity 26, and the output end of the motor 27 passes through the top of the driving cavity 26.

[0045] like Figure 2 , Figure 4 , Figure 5As shown, a cam 31 is sleeved on the cylinder 8, and two inflatable cylinders 35 are horizontally symmetrically arranged on both sides of the cam 31. The lower part of each inflatable cylinder 35 is connected to the bottom of the bed body 1, and a piston 36 is arranged in each inflatable cylinder 35. A moving block 32 is arranged between each inflatable cylinder 35 and the cam 31. The moving block 32 contacts the edge of the cam 31, and the lower part of the moving block 32 is slidably connected to the bottom of the bed body 1. The moving block 32 and the corresponding piston 36 are connected through a horizontally arranged push rod 37. The position of the push rod 37 between the inflatable cylinder 35 and the moving block 32 is sleeved with a first elastic member 22. The first elastic member 22 facilitates the corresponding moving block 32 to reset after moving, and at the same time, it can also make the moving block 32 It is always in contact with the cam 31, and the end of each inflation cylinder 35 away from the cam 31 is a closed structure. An inflation tube 15 is vertically arranged on the upper part of each inflation cylinder 35, and a first air bag 44 is arranged on the upper end of the inflation tube 15. The inflation tube 15 is connected with the inflation cylinder 35 and the first air bag 44 respectively. A solenoid valve 17 is arranged on the inflation tube 15, and a detection control component is arranged on the bed board 2. The detection control component is used to detect the rotation direction of the bed board 2 and control the opening of the solenoid valve 17 in the corresponding direction, so that the corresponding first air bag 44 pushes the bed board 2 upward after expansion, provides an upward force for the bed board 2, and further actively adjusts the inclination of the bed board 2, thereby further accelerating the bed board 2 to recover from inclination to horizontal.

[0046] like Figure 2As shown, the detection control component includes a dynamic tilt sensor 45 and a controller 46. The dynamic tilt sensor 45 is arranged at the lower part of the bed board 2. The dynamic tilt sensor 45 is used to detect the rotation angle value of the bed board 2. The controller 46 is arranged on the bed body 1. The controller 46 is electrically connected to the dynamic tilt sensor 45, two solenoid valves 17, and the motor 27 respectively. The controller 46 is used to receive the rotation angle value detected by the dynamic tilt sensor 45, and judge the rotation direction of the bed board 2 according to the positive or negative rotation angle value, and control the corresponding solenoid valve 17 in the rotation direction to open. When the controller 46 receives the rotation angle value detected by the dynamic tilt sensor 45 as a positive value, it means that the bed board 2 rotates clockwise around the rotating shaft 6. At this time, the right side of the bed board 2 swings downward, and the controller 46 controls the right side solenoid valve 17 close to the bed board 2 to open, so that the inflatable Part of the air in the cylinder 35 enters the first airbag 44 on the right, so that the first airbag 44 on the right expands and stretches to contact the lower part of the bed board 2 on the right, providing an upward force to the lower part of the bed board 2 on the right, further accelerating the bed board 2 to recover from tilting to horizontal. When the controller 46 receives a negative value of the rotation angle value detected by the dynamic tilt sensor 45, it represents that the bed board 2 rotates counterclockwise around the rotating shaft 6. At this time, the left side of the bed board 2 swings downward, and the controller 46 controls the left solenoid valve 17 close to the bed board 2 to open, so that part of the air in the inflation cylinder 35 enters the first airbag 44 on the left, so that the first airbag 44 on the left expands and stretches to contact the lower part of the bed board 2 on the left, providing an upward force to the lower part of the bed board 2 on the left, further accelerating the bed board 2 to recover from tilting to horizontal, thereby further actively adjusting the inclination of the bed board 2.

[0047] like Figure 2 As shown, second counterweight balls 10 are respectively arranged below the bed board 2 near the positions above the two first airbags 44, and a connecting rod 11 is vertically arranged between each second counterweight ball 10 and the bed board 2. The upper end of the connecting rod 11 is hinged to the bed board 2, and the lower end of the connecting rod 11 is connected to the corresponding first counterweight ball 9, so that each second counterweight ball 10 can swing left and right with the connecting rod 11. There is a gap between each second counterweight ball 10 and the upper part of the corresponding first airbag 44, so that the corresponding second counterweight ball 10 can be driven to move upward after the first airbag 44 expands and stretches, and the gravity of the two second counterweight balls 10 can further accelerate the bed board 2 to recover from tilt to horizontal.

[0048] like Figure 5 As shown, the first airbag 44 is a columnar structure. The first airbag 44 is vertically arranged, and the lower end of the first airbag 44 is connected to the upper end of the inflation tube 15, so that the first airbag 44 can stretch upward after being inflated, so that the force generated by the expansion is more concentrated, providing greater force for the restoration of the bed board 2, and further accelerating the bed board 2 to recover from tilt to horizontal.

[0049] like Figure 2 , Figure 6As shown, the elastic lifting assembly includes multiple telescopic rods 41, multiple support blocks 12, and multiple second elastic members 23. The multiple telescopic rods 41 are vertically arranged on the upper part of the disc 7, and the multiple telescopic rods 41 are evenly arranged along the edge of the disc 7. The lower end of each telescopic rod 41 is connected to the disc 7. The multiple support blocks 12 correspond to the multiple telescopic rods 41 one by one. Each support block 12 is arranged at the upper end of the corresponding telescopic rod 41. The upper part of each support block 12 contacts the lower part of the bed board 2. The multiple second elastic members 23 correspond to the multiple telescopic rods 41 one by one. Each second elastic member 23 is sleeved on the corresponding telescopic rod 41. The two ends of each second elastic member 23 are respectively connected to the support block 12 and the disc 7. Each second elastic member 23 facilitates the corresponding support block 12 to reset after moving downward.

[0050] like Figure 6 As shown, a second ball groove 14 is opened on the upper part of each support block 12, and a moving ball 18 is arranged in the second ball groove 14. The upper part of the moving ball 18 contacts the lower part of the bed board 2, and the moving ball 18 can rotate freely in the second ball groove 14, thereby reducing the friction force when the support block 12 slides along the lower part of the bed board 2.

[0051] like Figure 2 , Figure 7 As shown, the upper part of the cylinder 8 is a closed structure, and a first ball groove 13 is opened at the upper part of the cylinder 8 near the connecting shaft 19. A universal ball 16 is arranged in the first ball groove 13. The universal ball 16 can rotate freely in the first ball groove 13. The connecting shaft 19 passes through the universal ball 16 and is fixedly connected to the universal ball 16. The lower part of the cylinder 8 is rotatably connected to the bottom of the bed 1 to facilitate the free rotation of the cylinder 8.

[0052] like Figure 4 , Figure 7 As shown, a plurality of third elastic members 24 are evenly and horizontally arranged around the first counterweight ball 9 in the cylinder 8, and the two ends of each third elastic member 24 are respectively connected to the inner wall of the cylinder 8 and the first counterweight ball 9. The elastic force of the plurality of third elastic members 24 provides additional restoring force for the first counterweight ball that rotates with the cylinder, so that the elastic force is combined with the gyro effect to accelerate the resetting of the first counterweight ball, and further actively adjust the inclination of the bed board, thereby further accelerating the recovery of the bed board from inclination to horizontal.

[0053] like Figure 2 , Figure 8 , Fig. 9As shown, a storage plate 43 is provided along the edge of the upper part of the bed board 2, and a storage groove 43 is provided on the inner side of the storage plate 43, and a second air bag 47 is provided in the storage groove 43, so that the second air bag 47 is a quadrilateral, and a first connecting tube 30 is provided between each inflatable cylinder 35 and the second air bag 47, and the lower end of the first connecting tube 30 is connected to the end of the corresponding inflatable cylinder 35 away from the cam 31, and the upper end of the first connecting tube 30 is connected to the second air bag 47, and a one-way valve 38 is provided on the first connecting tube 30 and the inflatable cylinder 35 respectively, and the position of the one-way valve 38 on each inflatable cylinder 35 is close to the corresponding first connecting tube 30, and the one-way valve 38 on each first connecting tube 30 is used to allow the air inside to flow from the inflatable cylinder 35 to the second air bag 47 in a one-way direction. The one-way valve 38 on each inflation cylinder 35 is used to allow air to flow unidirectionally from the outside of the inflation cylinder 35 to the inside of the inflation cylinder 35. When the cylinder body 8 rotates, the cam 31 is driven to rotate, and the cam 31 drives each moving block 32 to move back and forth continuously. Each moving block 32 drives the piston 36 to slide back and forth in the corresponding inflation cylinder 35 through the push rod 37, so that air is filled into the second airbag 47 through the two first connecting tubes 30, so that the second airbag 47 expands, and the second airbag 47 is inflated when going up and down slopes. The second airbag 47 expands to squeeze and fix the critically ill patient around, thereby preventing the critically ill patient from sliding, thereby further preventing the critically ill patient from local skin or subcutaneous tissue damage under the action of continuous pressure.

[0054] like Fig. 9 As shown, third connecting tubes 34 are laterally arranged inside the bed board 2 near the two first connecting tubes 30, and both ends of the third connecting tubes 34 are respectively connected to the second airbags 47. The third connecting tubes 34 are connected to the corresponding first connecting tubes 30, so as to facilitate the rapid inflation of the second airbags 47. At the same time, a valve is provided on the second airbag 47 to release the internal air when it is not in use.

[0055] like Figure 2 , Figure 4As shown, the elastic support assembly includes four plunger hydraulic cylinders 28, four fourth elastic members 25 and a guide assembly. The four plunger hydraulic cylinders 28 are vertically arranged below the bed board 2. The positions of the four plunger hydraulic cylinders 28 are respectively close to the four corners of the bed board 2. The upper end of each plunger hydraulic cylinder 28 is hinged to the bed board 2, and the lower end of each plunger hydraulic cylinder 28 is connected to the bottom of the bed body 1. The four fourth elastic members 25 correspond to the four plunger hydraulic cylinders 28 one by one. Each fourth elastic member 25 is sleeved on the corresponding plunger hydraulic cylinder 28, so that the bed board 2 can be reset after swinging through the four fourth elastic members 25. The guide assembly is arranged at the bottom of the bed body 1, and the guide assembly is respectively connected to the four plunger hydraulic cylinders 28. The guide assembly is used to balance the pressure inside the four plunger hydraulic cylinders 28, so that the bed board 2 can be restored to a horizontal state through the balance of the internal pressure of the four plunger hydraulic cylinders 28, so that the process of restoring the horizontal state of the bed board 2 is smoother.

[0056] like Fig.10 As shown, the guide assembly includes an annular liquid storage chamber 29 and four second connecting pipes 33. The annular liquid storage chamber 29 is arranged inside the bottom of the bed body 1. Hydraulic oil is arranged in the annular liquid storage chamber 29, and the pressure inside the four plunger hydraulic cylinders 28 is transmitted through the hydraulic oil. The four second connecting pipes 33 are respectively arranged between the four plunger hydraulic cylinders 28 and the annular liquid storage chamber 29. The two ends of each second connecting pipe 33 are respectively connected to the annular liquid storage chamber 29 and the corresponding plunger hydraulic cylinder 28. Each second connecting pipe 33 is a hose to avoid affecting the up and down swinging of the bed board 2 for leveling. When the two plunger hydraulic cylinders 2 at the same end are subjected to the downward pressure from the end of the bed board 2 and then contract, the internal pressure thereof increases, and the pressure is transmitted to the other two plunger hydraulic cylinders 2 through the hydraulic oil, so that the other two plunger hydraulic cylinders 2 are stretched under the force.

[0057] like Figure 2As shown, each transmission rod 11 is an electric telescopic structure, the upper end of each transmission rod 11 contacts the lower part of the bed board 2, a dynamic tilt sensor 45 is provided at the lower part of the bed board 2, a controller 46 is provided on the bed body 1, and the controller 46 is electrically connected to the dynamic tilt sensor 45, the two transmission rods 11, and the motor 27, respectively. The dynamic tilt sensor 45 is used to detect the rotation angle of the bed board 2 in real time and feed it back to the controller 46. The controller 46 is used to control the start and stop of the two transmission rods 11 and the motor 27. When on a horizontal road surface, the upper ends of the two transmission rods 11 are against The bed board 2 fixes the position of the bed board 2 so that the bed board 2 will not swing around the rotating shaft 6, making the movement smoother. When on an uphill or downhill slope, the dynamic inclination sensor 45 detects the rotation angle of the bed board 2 and feeds it back to the controller 46. The controller 46 compares the detected rotation angle with 0°. When the detected rotation angle is not equal to 0°, the controller 46 starts the two transmission rods 11, causing the two transmission rods 11 to retract, canceling the fixation of the position of the bed board 2, and then the controller 46 starts the motor 27 to actively adjust the rotation angle of the bed board 2.

[0058] like Figure 1 , Figure 2 As shown, first guardrails 39 are vertically provided on the upper part of the bed body 1 near the left and right ends, and second guardrails 40 are vertically provided on the upper part of the bed body 1 near the front and rear sides. The second guardrail 40 is connected to the upper part of the bed body 1 by a hinge to facilitate the rotation of the second guardrail 40 so that critically ill patients can be quickly placed on the bed board 2.

[0059] Working principle: When in use, a critically ill patient is placed on the bed board 2 for intra-hospital or inter-hospital transfer. When encountering ups and downs during the transfer process, the bed board 2 tilts along with the bed body 1 as a whole, and the dynamic inclination sensor 45 detects the rotation angle value of the bed board 2 and feeds it back to the controller 46. The controller 46 compares the detected rotation angle value with 0°. When the detected rotation angle value is not equal to 0°, the controller 46 starts the two transmission rods 11, causing the two transmission rods 11 to contract, canceling the fixation of the position of the bed board 2, and then the controller 46 starts the motor 27, the motor 27 drives the cylinder 8 to rotate, and the cylinder 8 drives the disc 7 to rotate through the two transmission rods 21, and the disc 7 is connected to the shaft 1. 9 drives the first counterweight ball 9 to rotate, so that the first counterweight ball 9 has a gyro effect after being tilted. Under the action of its own gravity and the gyro effect, the first counterweight ball 9 accelerates the first counterweight ball 9 to return to the vertical state, thereby accelerating the disk 7 to recover from tilt to the horizontal state, driving the multiple telescopic rods 41 and the multiple support blocks 12 to quickly recover from tilt to the vertical state, accelerating the bed board 2 to recover from tilt to the horizontal state, and actively adjusting the tilt of the bed board 2. At the same time, the multiple support blocks 12 follow the rotation of the disk 7, and the multiple support blocks 12 passing through the lower part of the bed board 2 at a lower tilt position and their corresponding second elastic members 23 continuously provide an upward force to the bed board 2, further accelerating the bed board 2 to recover from tilt to the horizontal state.

[0060] At the same time, when the cylinder 8 rotates, the cam 31 is driven to rotate, and the cam 31 drives each moving block 32 to move back and forth continuously. Each moving block 32 drives the piston 36 to slide back and forth in the corresponding inflation cylinder 35 through the push rod 37, so that air is filled into the second airbag 47 through the second connecting tube 33, so that the second airbag 47 expands to squeeze and fix the critically ill patient around, thereby preventing the critically ill patient from sliding.

[0061] At the same time, when the controller 46 receives a positive value of the rotation angle detected by the dynamic inclination sensor 45, it means that the bed board 2 rotates clockwise around the rotating shaft 6. At this time, the right side of the bed board 2 swings downward, and the controller 46 controls the right solenoid valve 17 close to the bed board 2 to open, so that part of the air in the inflation cylinder 35 enters the first air bag 44 on the right, so that the first air bag 44 on the right expands and stretches to contact the second counterweight ball 10 on the right, providing an upward force for the second counterweight ball 10 on the right, further accelerating the bed board 2 to recover from tilt to horizontal, thereby further actively adjusting the inclination of the bed board 2. When the controller 46 receives a negative value of the rotation angle detected by the dynamic inclination sensor 45, it means that the bed board 2 rotates counterclockwise around the rotating shaft 6, and the solenoid valve 17 on the left is controlled to open. The first air bag 44 on the left expands and stretches to provide an upward force for the second counterweight ball 10 on the left to accelerate the bed board 2 to recover from tilt to horizontal.
