Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of transportation tools for patients, and provides an intelligent transportation device for emergency patients. Background Art
[0002] In clinical practice, patient transfers are often necessary, for example: transferring a traumatized or paralyzed patient from a wheelchair to a supine position on a CT or MRI machine; transferring a patient from a ward to an operating room bed; and transferring a patient back to a ward or ICU bed after surgery. Currently, patient transfers are performed using a bed-to-wheelchair-to-bed or bed-to-bed method. These methods have the following disadvantages: they require significant manpower and are labor-intensive; improper handling can cause secondary injury to the patient; and transferring obese or overweight patients is particularly challenging. Bed transfers can block hospital access and take up elevator space; and patients must wait for an unused wheelchair, delaying their appointments or purchasing a wheelchair, which can increase the burden on the patient. Prior art CN213641630U provides a patient transport device comprising a support base and a soft support cushion for a patient to lie down on. The support cushion is disposed above the support base and is detachably connected to the support base. A connecting assembly is disposed between the support cushion and the support base, which is capable of securing the support base and the support cushion. The support cushion comprises a leaning portion, a sitting portion, and a supporting portion. The leaning portion is for the patient to lean on the back, the sitting portion is for supporting the patient's buttocks, and the supporting portion is for supporting the patient's legs. The supporting portion, the sitting portion, and the leaning portion are sequentially connected. The supporting portion and the sitting portion are hingedly connected. The end of the sitting portion away from the supporting portion is hingedly connected to the leaning portion. A support frame is disposed on the support base to support the support cushion. The inventor believes that there is considerable room for improvement in the prior art. Summary of the Invention
[0003] The purpose of the present invention is to provide a transportation device for patients, which can switch between a wheeled chair and a hospital bed, which is conducive to quickly providing a hospital bed and transferring emergency patients during first aid. Secondly, it avoids secondary injuries to patients caused by carrying patients during the transfer process; when passage is inconvenient, the hospital bed can be converted into a wheelchair, which is conducive to the flexible transportation of emergency patients; during the transfer of patients, obstacles along the way are monitored and alarmed to ensure the safety of the patient transfer process. To this end, the present invention provides an intelligent transportation device for emergency patients, including a support mechanism and a moving mechanism below the support mechanism, the support mechanism includes at least three sections of support frames connected in sequence, the support frame includes a middle support frame, the middle support frame is connected to the moving mechanism below, the support frame also includes a head support frame and a tail support frame, the head support frame can rotate in a direction away from the moving mechanism, and the tail support frame can rotate in a direction close to the moving mechanism. The support mechanism of the intelligent transport device adopts three sections of support frames connected in sequence, which is convenient for adjusting the shape of the intelligent transport device and shortening the length of the intelligent transport device, which is conducive to the intelligent transport device passing through transfer facilities and terrains with inconvenient passage, such as elevators with narrow cabins and stairs with small corner space; the head support frame can rotate in the direction away from the moving mechanism, and the tail support frame can rotate in the direction close to the moving mechanism. The intelligent transport device can be adjusted between the two forms of bed and wheelchair when changing its shape, and the head of the emergency patient can be kept not lower than the legs, thereby maintaining the comfort of the patient when the intelligent transport device adjusts its shape.
[0004] Preferably, the mobile mechanism includes at least two pairs of powered wheels, including front and rear powered wheels, and the distance between the front and rear powered wheels can be adjusted. The adjustable spacing between the powered wheels facilitates the intelligent transport device's adaptability to various terrains. Appropriately reducing the spacing between the front and rear powered wheels can ensure the intelligent transport device's maneuverability over rough terrain, while increasing the spacing between the front and rear powered wheels can improve the intelligent transport device's stability on flat terrain.
[0005] Preferably, the mobile mechanism further comprises a chassis adjustment device, the chassis adjustment device comprises a horizontal telescopic rod and a vertical telescopic rod, the front power wheel and the rear power wheel are connected by a horizontal telescopic rod, the power wheel and the middle support frame are connected by a vertical telescopic rod, and the distance between the power wheel and the middle support frame can be changed. The chassis adjustment device is provided with a vertical telescopic rod and a horizontal telescopic rod, so that the spacing between the front power wheel and the rear power wheel can be changed while changing the vertical distance between the front power wheel and the rear power wheel relative to the middle support frame. When the spacing between the front power wheel and the rear power wheel is changed, the vertical distance between the front power wheel and the rear power wheel relative to the middle support frame is adaptively changed, which is conducive to maintaining the stability of the intelligent transportation device and ensuring the safe transfer of patients. For example, when the spacing between the front power wheel and the rear power wheel is reduced, the vertical distance between the front power wheel and the rear power wheel relative to the middle support frame is shortened, the center of gravity of the intelligent transportation device is lowered, and the stability of the intelligent transportation device can remain unchanged.
[0006] Preferably, the central support frame includes a first support rod group, which connects the front power wheel and the rear support frame. The first support rod group can control the relative position of the front power wheel and the rear support frame. The arrangement of the first support rod group on the central support frame can increase the load-bearing strength of the rear support frame. At the same time, the use of the first support rod group to connect the rear support frame and the front power wheel facilitates adjustment of the position of the front power wheel when adjusting the rear support frame, avoids interference between the rear support frame and the front power wheel, and maintains the overall stability of the intelligent transport device.
[0007] Preferably, the central support frame further includes a second support rod group, which connects the rear powered wheel and the head support frame. The second support rod group can control the relative position of the front powered wheel and the head support frame. The provision of the second support rod group on the central support frame can increase the load-bearing strength of the head support frame. At the same time, the use of the second support rod group connecting the head support frame and the rear powered wheel facilitates adjustment of the position of the rear powered wheel in conjunction with adjustment of the head support frame, thereby maintaining the overall stability of the intelligent transportation device.
[0008] Preferably, a sensor bracket is provided on the top surface of the tail support frame, and the bottom of the sensor bracket is rotatably connected to the tail support frame. A pressure sensor is provided on the bottom of the sensor bracket, and the pressure sensor is located at the end of the tail support frame away from the middle support frame. The intelligent transportation device adopts a pressure sensor provided on the tail support frame. When the intelligent transportation device is adjusted to a wheelchair form, the patient generally triggers the pressure sensor under the action of gravity. When the intelligent transportation device is in the form of a hospital bed, the pressure sensor is located in a position that is difficult for the patient to trigger, which is conducive to locking the form of the intelligent transportation device and affecting the rotation of the sensor bracket. The use of a rotatable connection between the sensor bracket and the tail support frame facilitates the storage and use of the sensor bracket when needed.
[0009] Preferably, a pressure sensor is connected to a sensor bracket, which can affect the rotation of the sensor bracket. An obstacle avoidance sensor is provided on top of the sensor bracket. The sensor bracket is rotated vertically so that its top is significantly higher than the patient bed. This facilitates the obstacle avoidance sensor's ability to monitor surrounding obstacles, issue warnings of approaching obstacles, and even plan the path of the intelligent transport device to complete automated patient transfer. For example, the obstacle avoidance sensor utilizes a millimeter-wave radar positioned at a height higher than the patient bed, enabling unobstructed monitoring of obstacles surrounding the intelligent transport device.
[0010] Preferably, the pressure sensor has a triangular cross-section and is rotatably connected to the sensor bracket. The triangular cross-section of the pressure sensor allows the pressure sensor to rotate naturally under the action of gravity. The pressure sensor is activated only in a specific state, either during manipulation by an operator or when pressure is applied by a patient, thereby improving the safety of the device.
[0011] Preferably, the angle between the tail support frame and the ground is less than 90°. The angle between the tail support frame and the ground is always set to less than 90°. The triangular base of the cross section of the pressure sensor cannot be parallel to the ground in its natural state, thereby preventing the pressure sensor from being falsely triggered. When the pressure sensor is subjected to force, the triangular base of the cross section of the pressure sensor is parallel to the ground, and the support mechanism is locked, preventing the intelligent transportation device from being in a wheelchair configuration and suddenly adjusting its posture when the patient is in a sitting position.
[0012] Preferably, the rear support frame is provided with a first stopper, which is located at an end of the rear support frame away from the middle support frame. The first stopper and the rear support frame form an angle, and the pressure sensor is located near the connection between the first stopper and the rear support frame. The rear support frame is provided with the first stopper to provide support for the patient when the intelligent transportation device is in the wheelchair form; the pressure sensor is located near the connection between the first stopper and the rear support frame. The pressure sensor is located near the support position of the patient when the intelligent transportation device is in the wheelchair form, reducing the possibility of the pressure sensor not receiving a pressure signal.
[0013] The present invention provides a patient transportation device that can switch between a wheeled chair and a hospital bed, which is beneficial for quickly providing a hospital bed and transferring emergency patients during first aid; avoiding secondary injuries to patients caused by carrying patients during the transfer process; when passage is inconvenient, the hospital bed can be converted into a wheelchair, which is beneficial for flexible transportation of emergency patients; during the patient transfer process, obstacles along the way are monitored and alarmed to ensure the safety of the patient transfer process, and has the following beneficial effects: shortening the length of the intelligent transportation device, which is beneficial for the intelligent transportation device to pass through transfer facilities and terrains with inconvenient passage, such as elevators with narrow cabins and stairs with small corner space; the intelligent transportation device can be adjusted between the two forms of hospital bed and wheelchair when changing its appearance, and keep the head of the emergency patient not lower than the legs, so as to maintain the comfort of the patient when the intelligent transportation device adjusts its shape.

DETAILED DESCRIPTION
[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0018] Example 1 Combine Figures 1 to 3 As shown, an intelligent transportation device for emergency patients comprises a support mechanism 1 and a mobile mechanism 2 below the support mechanism 1. The support mechanism 1 comprises three sections of support frames connected in sequence, the support frame comprises a middle support frame 12, and the mobile mechanism 2 is connected below the middle support frame 12. The support frame also comprises a head support frame 11 and a tail support frame 13. The head support frame 11 can rotate in a direction away from the mobile mechanism 2, and the tail support frame 13 can rotate in a direction close to the mobile mechanism 2. The head support frame 11, the middle support frame 12 and the tail support frame are all provided with a restraint belt 4. The support mechanism 1 of the intelligent transport device adopts three sections of support frames connected in sequence, which is convenient for adjusting the shape of the intelligent transport device and shortening the length of the intelligent transport device, which is beneficial for the intelligent transport device to pass through transfer facilities and terrains with inconvenient passage, such as elevators with narrow cabins and stairs with small corner space; the head support frame 11 can rotate in the direction away from the moving mechanism 2, and the tail support frame 13 can rotate in the direction close to the moving mechanism 2. The adjustment method enables the intelligent transport device to be adjusted between the two forms of bed and wheelchair when changing its shape, and keeps the head of the emergency patient not lower than the legs, thereby maintaining the comfort of the patient when the intelligent transport device adjusts its shape.
[0019] like Figure 2 As shown, the mobile mechanism 2 includes two pairs of powered wheels, including a front powered wheel 21 and a rear powered wheel 22. The distance between the front powered wheel 21 and the rear powered wheel 22 can be changed. The adjustable spacing between the powered wheels helps the intelligent transport device adapt to various terrains. Appropriately reducing the spacing between the front powered wheel 21 and the rear powered wheel 22 can ensure the intelligent transport device's ability to pass through rough terrain, while increasing the spacing between the front powered wheel 21 and the rear powered wheel 22 can improve the intelligent transport device's stability on flat terrain.
[0020] like Figure 2 and Figure 4As shown, the mobile mechanism 2 also includes a chassis adjustment device 23, which includes a horizontal telescopic rod 23b and a vertical telescopic rod 23a. The horizontal telescopic rod 23b connects the front power wheel 21 and the rear power wheel 22, and the vertical telescopic rod 23a connects the power wheel and the middle support frame 12. The distance between the power wheel and the middle support frame 12 can be changed. The chassis adjustment device 23 is provided with a vertical telescopic rod 23a and a horizontal telescopic rod 23b, so that the spacing between the front power wheel 21 and the rear power wheel 22 can be changed while changing the vertical distance between the front power wheel 21 and the rear power wheel 22 relative to the middle support frame 12. When the spacing between the front power wheel 21 and the rear power wheel 22 is changed, the vertical distance between the front power wheel 21 and the rear power wheel 22 relative to the middle support frame 12 is adaptively changed, which is beneficial to maintaining the stability of the intelligent transportation device and ensuring the safe transfer of patients. For example, when the distance between the front power wheels 21 and the rear power wheels 22 is reduced, the vertical distance between the front power wheels 21 and the rear power wheels 22 relative to the middle support frame 12 is shortened, the center of gravity of the intelligent transportation device is lowered, and the stability of the intelligent transportation device can remain unchanged.
[0021] like Figure 2 and Figure 5 As shown, the middle support frame 12 includes a first support rod group 12a, which connects the front power wheel 21 and the rear support frame 13. The first support rod group 12a can control the relative position of the front power wheel 21 and the rear support frame 13. The provision of the first support rod group 12a on the middle support frame 12 can improve the load-bearing strength of the rear support frame 13. At the same time, the use of the first support rod group 12a to connect the rear support frame 13 and the front power wheel 21 facilitates the adjustment of the position of the front power wheel 21 when adjusting the rear support frame 13, avoiding interference between the rear support frame 13 and the front power wheel 21, and maintaining the overall stability of the intelligent transportation device.
[0022] The central support frame 12 also includes a second support rod group 12b, which connects the rear powered wheel 22 and the head support frame 11. The second support rod group 12b can control the relative position of the front powered wheel 21 and the head support. The provision of the second support rod group 12b in the central support frame 12 can increase the load-bearing strength of the head support frame 11. At the same time, the use of the second support rod group 12b to connect the head support frame 11 and the rear powered wheel 22 facilitates the adjustment of the position of the rear powered wheel 22 when adjusting the head support frame 11, thereby maintaining the overall stability of the intelligent transportation device.
[0023] like Figure 2 and Figure 3As shown, the tail support frame 13 is provided with a first stopper, which is located at the end of the tail support frame 13 away from the middle support. The first stopper is perpendicular to the tail support frame 13, and the pressure sensor 31 is close to the connection between the first stopper and the tail support frame 13. The first stopper is provided on the tail support frame 13 to provide support for the patient when the intelligent transportation device is in the wheelchair form. The pressure sensor 31 is located near the connection between the first stopper and the tail support frame 13. The pressure sensor 31 is close to the support position of the patient when the intelligent transportation device is in the wheelchair form, reducing the possibility that the pressure sensor 31 does not receive the pressure signal.
[0024] Combine Figure 3 、 Figure 6 and Figure 7 As shown, the top surface of the tail support frame 13 is provided with a sensor bracket 3, and the bottom of the sensor bracket 3 is rotatably connected to the tail support frame 13. A pressure sensor 31 is provided at the bottom of the sensor bracket 3, and the pressure sensor 31 is located at the end of the tail support frame 13 away from the middle support frame 12. The intelligent transportation device adopts the installation of pressure sensor 31 on the tail support frame 13. When the intelligent transportation device is adjusted to the wheelchair form, the patient generally triggers the pressure sensor 31 under the action of gravity. When the intelligent transportation device is in the bed form, the pressure sensor 31 is located in a position that is difficult for the patient to trigger, which is conducive to locking the form of the intelligent transportation device and affecting the rotation of the sensor bracket 3. The use of the sensor bracket 3 and the tail support frame 13 in a rotatable connection facilitates the storage and use of the sensor bracket 3 when needed.
[0025] A pressure sensor 31 is connected to the sensor bracket 3 and can affect the rotation of the sensor bracket 3. An obstacle avoidance sensor 32 is installed on the top of the sensor bracket 3. When the sensor bracket 3 is rotated vertically, the top of the sensor bracket 3 is significantly higher than the patient bed. This allows the obstacle avoidance sensor 32 to monitor surrounding obstacles, issue warnings of approaching obstacles, and even plan the movement path of the intelligent transport device to complete automated patient transfer. For example, the obstacle avoidance sensor 32 uses a millimeter-wave radar that is elevated a certain height above the patient bed, enabling unobstructed monitoring of obstacles around the intelligent transport device.
[0026] The pressure sensor 31 has a triangular cross-section and is rotatably connected to the sensor bracket 3. The triangular cross-section of the pressure sensor 31 allows it to rotate naturally under the action of gravity. The pressure sensor 31 is activated only in specific states, such as during manipulation by an operator or when pressure is applied by a patient, thus improving the safety of the device.
[0027] Combine Figure 2 and Figure 5As shown, the angle between the tail support frame 13 and the ground is less than 90°. The angle between the tail support frame 13 and the ground is always set to less than 90°. The triangular base of the cross section of the pressure sensor 31 cannot be parallel to the ground in its natural state, preventing false triggering of the pressure sensor 31. When the pressure sensor 31 is subjected to force, the triangular base of the cross section of the pressure sensor 31 is parallel to the ground, and the support mechanism 1 is locked, preventing the intelligent transportation device from suddenly adjusting its posture when the patient is in a sitting position while the intelligent transportation device is in a wheelchair configuration, thereby improving the safety of the device.
[0028] The present invention provides a patient transportation device that can switch between a wheeled chair and a hospital bed, which is beneficial for quickly providing a hospital bed and transferring emergency patients during first aid; avoiding secondary injuries to patients caused by carrying patients during the transfer process; when passage is inconvenient, the hospital bed can be converted into a wheelchair, which is beneficial for flexible transportation of emergency patients; during the patient transfer process, obstacles along the way are monitored and alarmed to ensure the safety of the patient transfer process, and has the following beneficial effects: shortening the length of the intelligent transportation device, which is beneficial for the intelligent transportation device to pass through transfer facilities and terrains with inconvenient passage, such as elevators with narrow cabins and stairs with small corner space; the intelligent transportation device can be adjusted between the two forms of hospital bed and wheelchair when changing its appearance, and keep the head of the emergency patient not lower than the legs, so as to maintain the comfort of the patient when the intelligent transportation device adjusts its shape.
[0029] The above embodiments and / or implementation methods are only used to illustrate the preferred embodiments and / or implementation methods for realizing the technology of the present invention, and are not intended to limit the implementation methods of the technology of the present invention in any form. Any person skilled in the art may make slight changes to other equivalent embodiments without departing from the scope of the technical means disclosed in the content of the present invention, but they should still be regarded as technologies or embodiments that are essentially the same as the present invention.
