Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically, to a convenient transport device. Background Technology

[0002] When examining or performing surgery on frail patients, it is necessary to transfer them from their hospital beds to mobile beds. Medical staff need to manually lift the patient from the fixed bed and then transfer them to the mobile bed. On the one hand, medical staff need to be professionally trained to complete the patient transfer process; on the other hand, it is a physically demanding task for them.

[0003] Chinese patent CN105147482B discloses a lifting and transport device for paralyzed patients. Its key technical features include: a frame, a crossbeam, a support, a lateral movement mechanism, a longitudinal telescopic mechanism, and a vertical lifting mechanism. The device uses a gear and rack mechanism and a load-bearing guide rail to achieve smooth movement along the length of the bed. It uses a heavy-duty slide rail to support the patient's weight and to transfer the patient from inside to outside the bed. It uses an electric winch to lift and lower the patient, thus improving the structural stability and operational reliability of the transport device.

[0004] The above technical solution has the following drawbacks: before lifting the patient, the patient's upper body needs to be raised and a special sling needs to be put on; after being lifted, the patient's comfort level is poor due to the single point of force, and long-distance transport is not possible. Summary of the Invention

[0005] The purpose of this invention is to provide a convenient transport device that can easily assist the patient in lifting their upper body, and the patient's body can receive relatively even support during transport, thereby improving the patient's comfort and making it suitable for long-distance transport.

[0006] The embodiments of the present invention are achieved through the following technical solution: a convenient transfer device includes a frame, on which a carrying mechanism for carrying a patient and a supporting mechanism for supporting the patient are provided. Top beams are provided on both sides of the top of the frame along its length. Electric cylinders are provided at both ends of the top beams to drive the carrying mechanism to move vertically. The carrying mechanism includes a first carrying beam and a second carrying beam. Multiple carrying straps are provided between the first and second carrying beams. One end of each carrying strap is fixedly connected to the first carrying beam, and the other end is detachably connected to the second carrying beam. The frame also includes a lifting mechanism to assist in lifting the patient's upper body. The lifting mechanism includes a lifting cylinder and a drive assembly for driving the lifting cylinder up and down. Symmetrical through holes for the patient's hands are provided on both sides of the lifting cylinder. A gripping strap for the patient's hands is provided at the opening at the top of the through holes on the lifting cylinder. A lifting assembly for pulling the patient's shoulders is provided on the lifting cylinder on the side of the two through holes that are far apart from each other.

[0007] Furthermore, the lifting assembly includes a lifting belt and slides at both ends of the lifting belt. The lifting cylinder has two annular slides along its circumference. The two slides are slidably mounted on the two annular slides in a one-to-one correspondence. The slides are provided with positioning pins, and the annular slides have multiple positioning holes for the positioning pins to be inserted.

[0008] Furthermore, there are two sets of drive components, which are respectively mounted on two top beams and connected to both sides of the lifting cylinder; each set of drive components includes a dual-axis motor, and each of the two output shafts of the dual-axis motor is equipped with a lifting plate, and a lifting rope is wound on the lifting plate, with the ends of the lifting ropes fixedly connected to the lifting cylinder.

[0009] Furthermore, a snap-fit ​​piece is provided at the end of the bearing belt away from the first bearing beam. The thickness of the snap-fit ​​piece is greater than the thickness of the bearing belt. A through groove is provided on the second bearing beam along its own length for the snap-fit ​​piece to be inserted. A retaining strip is provided in the through groove and below the bearing belt. One of the electric cylinders on the top beam is fixedly connected to the first bearing beam, and the other electric cylinder on the top beam passes through the second bearing beam and is fixedly connected to the retaining strip.

[0010] Furthermore, the length direction of the bearing belts located at both ends is perpendicular to the length direction of the first bearing beam, and the multiple bearing belts located in the middle are arranged to cross each other in pairs.

[0011] Furthermore, the support mechanism includes two support plates, which are rotatably mounted on both sides of the frame. One of the support plates has a sliding positioning seat on the side away from the rotating end. Limiting strips are provided on both the upper and lower sides of the sliding positioning seat, and limiting grooves for the insertion of the limiting strips are provided on both the upper and lower surfaces of the support plate.

[0012] Furthermore, each of the four corners of the frame is provided with a base rod, and each base rod is provided with a caster wheel at its bottom end. The top of the base rod is rotatably mounted on the frame and can be retracted into the frame. A spring plate is provided between the frame and the base rod to limit the rotation of the base rod. Anti-rotation components are provided on both sides of the frame to prevent the base rod from rotating.

[0013] Furthermore, the anti-rotation component includes two anti-rotation blocks and a connecting rope connecting the two anti-rotation blocks. The cross-sectional shape of the anti-rotation block is dovetail-shaped, and anti-rotation grooves for sliding of the anti-rotation blocks are provided at the bottom end of the frame and the top end of the bottom rod.

[0014] Furthermore, guide wheels are provided at each of the four corners of the frame, and the guide wheels are fixedly mounted on the frame by wheel frames.

[0015] Furthermore, a suspension rod is provided at one end of the top of the frame, and multiple hooks are provided on the suspension rod.

[0016] The technical solutions of the embodiments of the present invention have at least the following advantages and beneficial effects:

[0017] 1. The present invention provides a lifting mechanism on the frame. First, the lifting cylinder raises the patient's hands so that the lifting strap can be placed on the patient's shoulders. Then, the lifting strap lifts the patient so that the patient's upper body can be raised before the patient is transferred. This makes it easier to move the carrying mechanism under the patient's body to support the patient.

[0018] 2. This invention utilizes the combined use of a carrying mechanism and a supporting mechanism. During the lifting and lowering of the patient, the carrying mechanism alone can be used. When a longer distance of patient transport is required, the carrying mechanism can be moved downwards to bring the patient's body into contact with the supporting mechanism, thereby improving the patient's comfort and safety during transport.

[0019] 3. This invention rotatably mounts the base rod at the bottom of the frame and restricts the rotation of the base rod with a spring plate and prevents the rotation of the base rod with an anti-rotation component, thus ensuring the stability of the frame during use and facilitating the process of the entire frame being loaded into the ambulance.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0031] Example 1

[0032] The following is for reference Figures 1-7 As shown, further explanation is provided in conjunction with specific embodiments, with reference to... Figure 1 As shown, this invention is a convenient transport device, including a frame 1. A carrying mechanism 2 for carrying a patient and a supporting mechanism 3 for supporting the patient are mounted on the frame 1. The carrying mechanism 2 provides temporary support for the patient, while the supporting mechanism 3, located below the carrying mechanism 2, provides support during patient transport. Top beams 11 are welded to both sides of the top of the frame 1 along its length. Electric cylinders 12 are fixedly mounted at both ends of the bottom surface of the top beams 11 to drive the carrying mechanism 2 to move vertically, thus moving the carrying mechanism 2 to a designated height. A lifting mechanism 4 is also installed on the frame 1 to assist in lifting the patient's upper body. The lifting mechanism 4 includes a lifting cylinder 41 and two sets of drive components 42, which are respectively mounted on the two top beams 11. Simultaneous activation of the two drive components 42 drives the lifting cylinder 41 to rise and fall vertically, thereby lifting the patient's upper body and facilitating the placement of the carrying mechanism 2 beneath the patient.

[0033] Reference Figure 1 , Figure 2As shown, the load-bearing mechanism 2 includes a first load-bearing beam 21 and a second load-bearing beam 22. Multiple load-bearing straps 23 connect the first load-bearing beam 21 and the second load-bearing beam 22. The length direction of the load-bearing straps 23 at both ends is perpendicular to the length direction of the first load-bearing beam 21. The multiple load-bearing straps 23 in the middle are arranged in pairs to increase the overall load-bearing capacity of the load-bearing straps 23, while also improving patient comfort and safety. One end of each load-bearing strap 23 is fixedly connected to the first load-bearing beam 21, and the other end is detachably connected to the second load-bearing beam 22. First, the frame 1 is moved as a whole to the outside of the hospital bed, so that the hospital bed is located within the frame formed by the frame 1. Then, the electric cylinder 12 drives the first load-bearing beam 21 and the second load-bearing beam 22 to move synchronously to the height of the hospital bed surface. Since the patient's legs are relatively light and most patients can cooperate to some extent, the load-bearing straps 23 located below the patient's legs can be easily connected to the second load-bearing beam 22. For the support belt 23 located below the patient's back, the patient's upper body needs to be lifted. The lifting mechanism 4 is activated to lift the patient's upper body, allowing the end of the support belt 23 located below the patient's back to be connected to the second support beam 22. After connection, multiple support belts 23 can jointly support the patient. The patient can be raised and lowered synchronously by the electric cylinder 12 driving the first support beam 21 and the second support beam 22. During routine examinations such as ultrasound or electrocardiograms, the patient can be moved and maintained at an appropriate height for convenient examination without having to move the patient from the support mechanism 2 to the examination bed.

[0034] Reference Figure 2As shown, the detachable connection between the bearing belt 23 and the second bearing beam 22 is as follows: the end of the bearing belt 23 away from the first bearing beam 21 is provided with a snap-fit ​​piece 24, the thickness of the snap-fit ​​piece 24 is greater than the thickness of the bearing belt 23, and the second bearing beam 22 is provided with a through groove 221 for the snap-fit ​​piece 24 to be inserted along its own length direction. A retaining strip 25 is installed in the through groove 221 and below the bearing belt 23. The electric cylinder 12 on one of the top beams 11 is fixedly connected to the first bearing beam 21, and the electric cylinder 12 on the other top beam 11 passes through the second bearing beam 22 and is fixedly connected to the retaining strip 25. When installing the support belt 23 onto the second support beam 22, it is only necessary to insert the snap-fit ​​piece 24 at the end of the support belt 23 into the through groove 221 on the second support beam 22, which is simple and convenient. After all the support belts 23 are installed, the electric cylinder 12 is activated and the piston rod of the electric cylinder 12 moves into the cylinder barrel. Two of the electric cylinders 12 drive the clamping strip 25 to move upward and bring the support belt 23 into contact with the top wall of the through groove 221. Since the thickness of the snap-fit ​​piece 24 is greater than the thickness of the support belt 23, it will remain outside the through groove 221 and cannot pass through the through groove 221, thus limiting the support belt 23 and preventing it from moving out of the through groove 221, ensuring safety during the patient lifting process. During the process of the piston rod of the electric cylinder 12 moving out of the cylinder barrel, under the action of the patient's gravity, the clamping strip 25 will still drive the support belt to stick tightly to the top wall of the through groove 221, thus still ensuring that the support belt 23 does not move out of the through groove 221.

[0035] Reference Figure 3 As shown, the support mechanism 3 includes two support plates 31, which are rotatably mounted on both sides of the frame 1. One of the support plates 31 has a sliding positioning seat 32 on the side away from the rotating end. Limiting strips 321 are provided on both the upper and lower sides of the sliding positioning seat 32. Limiting grooves 311 for the insertion of the limiting strips 321 are provided on both the upper and lower surfaces of the support plate 31. When the support mechanism 3 is not in use, both support plates 31 are in a vertical state under their own weight. When a long-distance transport of the patient is required, both support plates 31 are rotated to a horizontal state, and the relative position between the two support plates 31 is fixed by the sliding positioning seat 32. Then, the carrying mechanism 2 is moved downward and the patient's body is brought into contact with the support plates 31. At this time, the support plates 31 can provide further support for the patient and improve the patient's comfort during the transport process.

[0036] Reference Figure 4As shown, the lifting cylinder 41 has symmetrical through holes 411 on both sides for the patient's hands to enter. The thickness of the through holes 411 is greater than the thickness of the patient's arm but less than the thickness of the patient's hand when clenched into a fist. A grip strap 412 is provided on the lifting cylinder 41 at the top opening of the through holes 411 for the patient to hold. When the patient inserts their hand into the bottom opening of the through hole 411 and removes it from the top opening, the patient's hand grips the grip strap 412, thus preventing the hand from slipping out of the through hole 411 during the lifting process, facilitating the lifting of the patient. For patients with some mobility, they only need to grip the grip strap 412 themselves. For patients without mobility, medical staff need to apply some external force to assist the patient's hand in gripping the grip strap 412. A lifting component 43 for pulling the patient's shoulder is provided on the lifting cylinder 41 on the side of the two through holes 411 that are far apart from each other. Once the lifting cylinder 41 lifts the patient up until the patient's shoulder leaves the bed, the lifting component 43 can apply force to the patient's shoulder. At this point, the patient's hand can release the grip strap 412. Therefore, the patient does not need to apply force for a long time, which reduces the difficulty of applying force.

[0037] Reference Figure 4 , Figure 5 As shown, the lifting assembly 43 includes a lifting strap 431 and slide blocks 432 fixedly connected to both ends of the lifting strap 431. Two annular slide rails 413 are circumferentially arranged on the lifting cylinder 41, and the two slide blocks 432 are slidably mounted on the two annular slide rails 413 in a one-to-one correspondence. Both sides of the slide block 432 are provided with bent portions 4322. Annular grooves 4132 are formed on both sides of the contact surface between the annular slide rails 413 and the lifting cylinder 41. The bent portions 4322 are located within the annular grooves 4132, limiting the movement of the slide block 432 and preventing separation from the annular slide rails 413. Positioning pins 4321 pass through the slide block 432, and multiple positioning holes 4131 are formed on the annular slide rails 413 for inserting the positioning pins 4321. When the patient's shoulder is separated from the bed, the slide 432 is slid according to the patient's body shape, and the position of the slide 432 is fixed by the positioning pin 4321, which can change the initial height of the lifting strap 431, so as to make it easy to put the lifting strap 431 on the shoulder of patients of different body shapes.

[0038] Reference Figure 4As shown, two sets of drive components 42 are symmetrically arranged on both sides of the lifting cylinder 41. Each set of drive components 42 includes a dual-axis motor 421. Each of the two output shafts of the dual-axis motor 421 is equipped with a lifting plate 422. A lifting rope 423 is wound around the lifting plate 422, and the ends of the lifting rope 423 are fixedly connected to the lifting cylinder 41. Simultaneously activating both dual-axis motors 421 causes their output shafts to drive the lifting plate 422 to rotate. During this rotation, the lifting plate 422 pulls the lifting cylinder 41, thereby lifting the patient's upper body upwards.

[0039] Furthermore, referring to Figure 6 As shown, guide wheels 16 are installed at each of the four corners of the frame 1, and each guide wheel 16 is fixed to the frame 1 by a wheel frame. When medical staff push the frame 1 around the hospital, if other pedestrians or transport devices pass by in the opposite direction in the corridor, the guide wheels 16 are pressed against the wall to ensure that the frame 1 is kept close to the corridor as much as possible. At the same time, the guide wheels 16 prevent the frame 1 from colliding with the wall, avoiding vibration injury to the patient. A suspension rod 17 is installed at the top of the frame 1, and multiple hooks 171 are provided on the suspension rod 17. For some special patients, such as those who need intravenous infusion during transport, the infusion bottle can be hung on the hooks 171 to ensure the patient's infusion needs during transport. An instrument placement plate 18 is fixedly installed at one end of the frame 1 to facilitate the placement of monitoring instruments such as electrocardiogram monitors, fetal heart monitors, or respiratory monitors.

[0040] Reference Figure 6As shown, the frame 1 has base rods 13 at each of its four corners. Each base rod 13 has a caster wheel 131 at its bottom end. The caster wheel 131 is equipped with a brake to facilitate fixing the frame 1 in its moved position. The top of the base rod 13 is rotatably connected to the frame 1 and can retract towards the center of the frame 1 along its length. A spring plate 14 is provided between the frame 1 and the base rod 13 to limit the rotation of the base rod 13. Anti-rotation components 15 are provided on both sides of the frame 1 to prevent the base rod 13 from rotating. When a patient needs to be transferred to another hospital for treatment, the entire transport device can be pushed into the ambulance to quickly transport the patient. Alternatively, the patient can be moved from the transport device to a stretcher, and then the stretcher can be moved into the ambulance. During the pushing of the frame 1, the anti-rotation component 15 can prevent the bottom rod 13 from rotating, thus ensuring the stability of the frame 1. When the frame 1 is pushed close to the ambulance, the anti-rotation component 15 is moved out of the bottom rod 13. Under the action of the spring plate 14, the frame 1 can remain stable without being subjected to external force. When the frame 1 is pushed to contact the ambulance compartment, the bottom rod 13 can rotate towards the center position in the length direction of the frame 1 under the action of external force. After the front end of the frame 1 enters the ambulance, the staff rotates the bottom rod 13 at the rear end of the frame 1 towards the center position in the length direction of the frame 1, which can complete the storage of the bottom rod 13, thereby enabling the entire frame 1 to quickly enter the ambulance and save rescue time.

[0041] Reference Figure 6 , Figure 7 As shown, the anti-rotation component 15 includes two anti-rotation blocks 151 and a connecting rope 152 connecting the two anti-rotation blocks 151. One anti-rotation block 151 is located at the front end of the frame 1, and the other anti-rotation block 151 is located at the rear end of the frame 1. The cross-sectional shape of the anti-rotation block 151 is dovetail-shaped. Anti-rotation grooves for sliding of the anti-rotation block 151 are provided at the bottom end of the frame 1 and the top end of the bottom rod 13. In the initial state, the bottom of the anti-rotation block 151 is located in the anti-rotation groove of the bottom rod 13, and the top of the anti-rotation block 151 is located in the anti-rotation groove of the frame 1. Therefore, there will be no relative rotation between the bottom rod 13 and the frame 1. When the medical staff lifts the connecting rope 152 upward, the anti-rotation block 151 moves upward as a whole until it is completely located in the anti-rotation groove of the frame 1. At this time, the limiting effect between the bottom rod 13 and the frame 1 is released. When subjected to external force, as long as the magnitude of the external force is greater than the elastic force of the spring plate 14, the spring plate 14 can be bent, thereby enabling the bottom rod 13 to rotate.

[0042] The working process of this embodiment is as follows: The frame 1 is moved so that the hospital bed is positioned within the frame formed by the frame 1. Then, the electric cylinder 12 drives the first support beam 21 and the second support beam 22 to move synchronously to the height of the hospital bed surface. Medical staff manually lift the patient's legs and connect the support strap 23 located below the legs to the second support beam 22. The lifting mechanism 4 is activated to lift the patient's upper body, and then the end of the support strap 23 located below the patient's back is connected to the second support beam 22. The electric cylinder 12 is activated to move the patient upwards a certain distance, facilitating the movement of the frame 1 to the outside of the hospital bed. Both support plates 31 are rotated to a horizontal position, and the relative position between the two support plates 31 is fixed by the sliding positioning seat 32. Then, the support mechanism 2 is moved downwards so that the patient's body contacts the support plates 31, thus providing further support to the patient and improving the patient's comfort and safety during transport.

[0043] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
