To further illustrate the embodiments, the present invention provides the accompanying drawings. The accompanying drawings, which are incorporated in and constitute a part of this disclosure, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the embodiments. With these references, one of ordinary skill in the art will appreciate other possible embodiments and advantages of the present invention. Elements in the figures are not drawn to scale and like reference numerals are generally used to indicate like elements.

The present invention will now be further described with reference to the accompanying drawings and detailed description.

As shown in fig. 1 to 8, a medical bed may include a liftable support frame 1, a bed plate 2, a conveyor belt assembly, and an electric cabinet 4. The liftable supporting frame 1 can comprise a base 11, two liftable pillars 12 and two beams 13, wherein the base 11 is composed of a longitudinal support 111 and two transverse supports 112. The lateral bracket 112 is mounted on the longitudinal bracket 111 at one end and is mounted with a caster (e.g., a universal wheel) 15 at the bottom of the other end. Preferably, the transverse bracket 112 is sleeved on the longitudinal bracket 111, i.e. the transverse bracket 112 can move on the longitudinal bracket 111. Therefore, the distance between the two lateral supports 112 can be adjusted to suit different hospital or operating beds (hospital beds are taken as an example for the following description). In the embodiment shown, the longitudinal support 111 and the two transverse supports 112 form a pi-shape. The longitudinal bracket 111 and the two lateral brackets 112 may be machined from thick steel plates to ensure stability. Casters 15 are mounted at the bottoms of both ends of the longitudinal support 111. In one embodiment, one of the casters 15 is a motorized roller (as shown in fig. 2 and 6) to facilitate automated walking of the hospital bed.

The liftable support columns 12 are fixedly installed (for example, by fasteners such as bolts) on the upper surfaces of both ends of the longitudinal support 111. The cross beam 13 is fixedly mounted (e.g., by a fastener such as a bolt) on the liftable column 12 at one end so as to be liftable, and suspended at the other end. The bed plate 2 is supported on a cross beam 13 so that the height of the bed plate 2 can be adjusted by lifting the support column 12. Therefore, the bed board 2 and the base 11 adopted by the embodiment form a U-shaped structure, so that the base 11 can be moved to the bottom of the sickbed, and the bed board 2 is superposed on the sickbed, thereby not only having a simpler and more compact structure, but also being convenient for the operation of medical staff. Hereinafter, for convenience of description, the open side of the U-shaped structure is referred to as a working side, and the other side is referred to as a non-working side.

In general, the above-mentioned open U-shaped structure can already meet the load-bearing requirements of the bed plate 2. In the present embodiment, however, it is further improved that the transverse support 112 is provided with an auxiliary support frame 8 (as shown in fig. 2 and 6) at an end near the working side for auxiliary support of the bed plate 2, so as to further increase the bearing capacity of the bed plate 2. The auxiliary support frame 8 may include a support frame 81 and an electric push rod 82 drivingly connected to the support frame 81, and the support frame 81 is driven by the electric push rod 82, so that the support portion at the upper end of the support frame 81 is in a state of supporting the top board 2 or the support portion at the upper end of the support frame 81 is away from the top board 2. The auxiliary supporting frame 8 may adopt a vertical lifting structure or a folding lifting structure. This embodiment preferably employs a folding lifting structure to further reduce the space occupation, so that the top end of the supporting frame 81 is mounted with a rotatable supporting block 83, and the top surface of the supporting block 83 is a cambered surface, for example, a wheel-shaped supporting block, to ensure that no damage (e.g., scratch) is caused to the bed plate 2 or the belt 32 of the belt conveying unit 3. The action of the electric push rod 82 is controlled by the electric cabinet 4. When the medical care bed is in a bearing state (not in a transferring process) or not in use, the supporting frame 81 is lifted to play a role in assisting in supporting the bed plate 2.

The auxiliary supporting frame 8 is specifically installed in such a way that the transverse support 112 is provided with a rectangular opening 1121, the lower end of the supporting frame 81 is rotatably installed in the opening 1121, the electric push rod 82 is fixedly installed in the opening 1121, and the end of the push rod is hinged with the supporting frame 81. The electric push rod 82 stretches out and draws back, drives the support frame 81 to rotate, namely, realizes that the support frame 81 is folded to be lifted up and lowered down, and the support frame 81 can be accommodated in the rectangular opening 1121 after being folded and lowered down, so that the purpose of reducing the occupied space is realized.

In this embodiment, the conveyor belt assembly is mounted on a bed plate 2 and comprises three belt conveyor units 3. The three belt conveying units 3 are arranged on the bed board at regular intervals. Of course, the number of belt conveying units 3 is not limited to the illustrated embodiment. The gaps between the belt conveyor units 3 are fitted with straps (not shown) of a thickness corresponding to the thickness of the belts to keep the bed flat. Preferably, the strap has a hook and loop fastener structure for easy operation. Of course the straps could be replaced by strips of cloth.

A belt pressure-proof plate 6 (for example, by a screw) is attached to the bottom of the bed plate 2 on the side facing the working side. A gap for the belt 32 to pass through is arranged between the belt pressure-proof plate 6 and the bed board 2. The belt 32 of the belt conveying unit 3 is wound around the bed plate 2 through a gap between the belt pressure-proof plate 6 and the bed plate 2 and can move transversely relative to the bed plate 2. Preferably, the upper surface of the portion of the bed plate at both ends without the belt 32 is covered with a cushion having the same thickness as the belt 32 to avoid discomfort of the patient.

In this embodiment, a lifting mechanism 51 is attached to the support frame 1 on the non-working side, and the lifting mechanism 51 lifts the non-working side of the bed to tilt the bed plate 2. In the process that the medical bed moves towards the sickbed, the bed board 2 is obliquely arranged, so that the height difference between the bed board 2 and the sickbed (or an operating table) on one side of the working side is reduced, meanwhile, the belt 32 is not in contact with the sickbed surface (or only in line contact), the surface friction is avoided, and the belt 32 is favorably conveyed.

The electric cabinet 4 is installed on the base 11 and used for controlling the actions of the lifting mechanism 51, the lifting support 12 and the belt conveying unit 3, and respectively driving the bed board to incline, driving the height adjustment of the bed board and driving the belt 32 on the bed board to convey so as to complete the transfer of the patient between the medical care bed and the patient bed (or operating table).

In addition, the base 11 is also provided with a driving wheel 52, and the whole support frame 1 (i.e. the whole medical bed) is driven to move by the driving wheel 52.

Since the walking movement of the hospital bed takes place in a non-transfer process, the driving wheel 52 of this embodiment is mounted at the end (end facing the ground) of the lifting mechanism 51 in order to further compress the structure.

Therefore, when the lifting mechanism 51 is retracted and the driving wheel 52 is not contacted with the ground, the medical bed can be manually moved by the caster 4; when the lifting mechanism 51 is ejected out to enable the driving wheel 52 to descend to be in contact with the ground, the driving wheel 52 and the caster 4 can automatically move; when the lifting mechanism 51 is further pushed out to incline the bed plate 2, the driving wheel 52 can drive the bed plate 2 to be further inserted into and overlapped with the sickbed.

In the preferred embodiment of this embodiment, the driving wheel 52 is attached to the distal end of the elevating mechanism 51, and in another embodiment, in the case where the driving wheel can be attached to the base 11 alone, a certain friction-reducing mechanism, for example, a pulley, can be attached to the distal end of the elevating mechanism 51 so that the elevating mechanism 51 can drive the medical bed tilting the bed plate by the driving wheel in the raised state.

In the present embodiment, in order to give way to the electric push rod 511 and the driving wheel 52 of the lifting mechanism 51, the middle of the longitudinal support 111 of the support frame 1 of the present embodiment has an opening 1111 passing through from top to bottom, and the opening 1111 is used for the electric push rod 511 and the driving wheel 52 to pass through. Preferably, the opening 1111 is a rectangular opening.

In this embodiment, the drive wheel 52 is a motorized roller. Of course, the driving wheel 52 can be replaced by other driving wheel structures composed of a motor, a wheel and a corresponding transmission mechanism.

Specifically, the lifting mechanism 51 comprises an electric push rod 511 and a roller mounting bracket 512, the electric push rod 5111 is mounted on the longitudinal support 111 at two sides of the opening, the roller mounting bracket 512 is in driving connection with the electric push rod 511, and the electric roller 52 is mounted on the roller mounting bracket 512.

In an embodiment (not shown), the driving wheel 52 may additionally include a steering mechanism, the steering mechanism being mounted on the lifting mechanism 51, and the driving wheel 52 being mounted on the steering mechanism. In this case, the driving wheel 52 is a motorized roller. Therefore, the orientation of the electric roller is changed through the steering mechanism, so that the medical bed can move transversely or longitudinally.

In order to facilitate the control of the moving direction of the hospital bed, the hospital bed is further provided with a control device 7. The handling device 7 can be mounted on the cross beam 13 or on the cover plate 14. In particular, the operating means 7 comprise operating levers located on both sides of the guard 14, on which operating buttons (for example, move or stop) can be provided.

As shown in fig. 5, the thickness of the bed plate 2 is gradually reduced from the non-working side to the working side. Preferably, the upper surface of the bed plate 2 is an inclined surface. The structure can further reduce the height difference between the bed board 2 and the sickbed under the condition of ensuring that the strength of the bed board is enough, and the bed board 2 is more easily inserted into the body of a patient on the basis of driving the bed board 2 to be obliquely arranged by matching with the lifting mechanism 51. In a specific embodiment, the bed plate 2 has a thickness of 3 cm on the non-working side and 1.5 cm on the working side. Preferably, the bed plate 2 is made of stainless steel.

As shown in fig. 2 and 8, at least one micro switch 61 (two shown) is mounted on the upper surface of the belt pressure-preventing plate 6. The microswitch 61 is located below the gap between the two belt conveyor units. It should be understood that the microswitch 61 may also be mounted on the bedplate bottom between the two belt conveyor units. In this case, the belt pressure guard 6 is movable relative to the bedplate 2. The microswitch 61 is in signal connection with the electric cabinet 4. When the micro switch 61 is actuated, it indicates that the bed board 2 has fully contacted with the hospital bed, at this time, the bed board 2 is automatically stopped from descending, so as to prevent the motor 121 of the liftable support 12 from being damaged due to overload. In one embodiment, a coil spring (not shown) is further sleeved outside the micro switch 61. The coil spring plays a role in protecting the microswitch 61 on one hand, and can ensure that the bed board 2 is in place in contact with a sickbed on the other hand.

Preferably, the vertical distance between the belt pressure-proof plate 6 and the bed plate 2 is 1-2 cm. The distance of the belt pressure-proof board 6 retracted into the bed board 2 is 2-5 cm. Thus, when the bed 5 is normally lifted by the lifting mechanism 51 to assume an inclination of 5 to 10 °, the belt guard 6 can assume an optimal support position which ensures that the height difference between the working side of the bed board 2 and the patient bed is low and that the belt 32 on the bed board 2 is transported smoothly without rubbing against the patient bed surface as much as possible.

Preferably, the belt pressure-preventive plate 6 is made of a stainless steel plate 3 mm thick.

With continued reference to fig. 2 and 8, the medical bed of this embodiment is further provided with a first position sensor and a second position sensor in signal connection with the electric cabinet 4, and the first position sensor and the second position sensor are respectively located on the working side and the non-working side. Specifically, the first position sensor is mounted on the mounting hole 62 of the belt presser 6, and the second position sensor is mounted on the mounting bracket 161 fixed to the side rail 16. Through first position sensor, can detect whether the bed board removes the sick bed, through second position sensor, can detect whether the bed board has overlapped on the sick bed. Preferably, the first and second position sensors are infrared sensors.

In addition, the hospital bed can be provided with a remote controller (not shown) which is in signal connection with the electric cabinet. The operation of the medical bed can be realized through the remote controller, and the operation is very convenient.

As shown in fig. 1 and 5, the belt conveying unit 3 may include a driving device 31, a belt 32, and a driven roller 33. The driving device 31 is installed on the non-working side of the bed board 2, the driven roller 33 is installed on the working side of the bed board 2, and the belt 32 is wound between the electric roller and the driven roller 33. The driving means 31 is generally composed of a motor and a drum. In the embodiment shown, the drive means 31 is a motorized drum. I.e. the motor and the reducer are built in the drum. This can simplify the structure and make the appearance more concise. Furthermore, the belt conveyor unit 3 may further comprise a press roller 34, which press roller 34 is mounted on the bedplate bottom near the non-working side for pressing the belt 32 against the bedplate 2.

A first pressure sensor 21 and a second pressure sensor 22 are mounted on the upper surface of the bed plate between the belt conveying units 3. The first pressure sensor 21 and the second pressure sensor 22 are used to determine whether the patient is positioned in the middle of the bed plate. The spacing between the first pressure sensor 21 and the second pressure sensor 22 is approximately equal to the width of the patient's body.

As shown in fig. 2-5, the deck 2 is slidably mounted on the support frame 1. Specifically, the two ends of the bed plate 2 are slidably engaged with the cross beam 13 through a sliding block 9. The slide block 9 comprises a slide block fixing frame 91, an upper Teflon slide block 92 and a lower Teflon slide block 93. The slide block fixing frame 91 is fixed on the bottom of the bed plate 2, and the slide block fixing frame 91 is provided with an L-shaped cross section. The upper Teflon slide block 92 is fixed on the bottom of the bed plate 2, and the lower Teflon slide block 93 is fixed on the slide block fixing frame 91. The beam 13 is slidably engaged between the upper teflon slide 92 and the lower teflon slide 93. Because the surfaces of the upper teflon slide block 92 and the lower teflon slide block 93 are smooth, the friction force between the upper teflon slide block and the cross beam 13 is small, so that the bed plate 2 can slide relative to the cross beam 13. The support frame 1 further comprises a vertical rod 16 parallel to and above the longitudinal support 111, and two ends of the vertical rod 16 are fixed on the liftable support 12. At least one slide actuator 10 (two shown) is mounted to the side rail 16. Specifically, the slide driving mechanism 10 includes an electric push rod 101, and a distal end of the electric push rod 101 is fixedly connected to the bottom of the bed plate 2 between the belt conveying units 3. The structure ensures that the bed board can extend out of the lifting support frame 1, and can be overlapped on a wider sickbed.

As shown in fig. 7, the lifting column 12 may include a motor 121, a motorized lifting rod 122, an inner hollow column 123, and an outer hollow column 124. The inner hollow strut 123 and the outer hollow strut 124 are rectangular struts.

The motor 121 is mounted on the base 11 (specifically, the longitudinal support 111) and is in driving connection with the electric lifting rod 122, and the cross beam 13 is fixed at the top end of the inner hollow pillar 123. The motor 121 drives the electric lifter 122 to move up and down, so that the inner hollow pillar 123 moves up and down relative to the outer hollow pillar 124, and further drives the cross beam 13 and the bed board supported on the cross beam 13 to lift. The lifting column 12 of this embodiment is simple, compact and reliable in construction.

In the present embodiment, the protective plates 14 are mounted on the cross beam 13, that is, the protective plates 14 are located at two ends of the bed board 2, so as to protect the head and the feet of the patient. Preferably, the guard plates 14 are formed integrally with the cross member 13, as shown in fig. 7.

In the present embodiment, the medical care bed comprises a movable guardrail 17, and the movable guardrail 17 is detachably arranged on the non-working side of the bed board 2. Of course, the movable fence 17 can also be arranged on the working side. Specifically, be equipped with the jack on bed board 2 or the backplate 14, be equipped with corresponding axle of inserting on the movable guardrail 17, movable guardrail 17 inserts through its axle of inserting the jack is realized installing on medical care bed, will insert the axle and extract from the jack during the dismantlement, faster operation.

The operation of the hospital bed of the present invention will now be briefly described with reference to fig. 1 to 8. Here, the transfer of a patient on a hospital bed to a hospital bed will be described as an example. Firstly, the medical care bed with the patient moves towards the sickbed (manually or automatically), the working side faces towards the sickbed, the auxiliary support frame 8 descends at the moment, and the liftable support 12 lifts the bed board 2 to the highest position; when the first position sensor at the bottom of the bed board 2 detects a signal, the liftable support 12 slowly descends the bed board 2 until the micro switch acts, and when the second position sensor at the bottom of the bed board 2 detects a signal, the movable support stops moving to the sickbed. The elevation structure 51 is then lowered to raise the non-working side to tilt the couch top, and the conveyor belt assembly is then activated (forward rotation) to transfer the patient thereon to the couch top. Because the bed surface is inclined, the height difference between the bed plate 2 and the sickbed does not exist, and the patient does not feel uncomfortable. When the patient is completely transferred to the sickbed, the conveyor belt assembly is stopped, the liftable support 12 lifts the bed board 2 up and moves outwards, and when the patient leaves the sickbed, the auxiliary support frame 8 can be lifted up to support the bed board in an auxiliary manner. The process of transferring the patient from the hospital bed to the hospital bed 1 is similar to the above process, firstly, the empty hospital bed moves to the hospital bed (which can be manually or automatically) where the patient is located, the working side faces the hospital bed, at this time, the auxiliary support frame 8 descends, and the liftable support 12 lifts the bed plate 2 to the highest position; when a first position sensor at the bottom of the bed plate 2 detects a signal, the liftable support 12 slowly descends the bed plate 2 until the microswitch is stopped, then the liftable structure 51 descends to lift the non-working side to incline the bed surface, then the bed plate 2 moves towards the sickbed, the bed plate 2 is inserted under the body of a patient, and when a second position sensor at the bottom of the bed plate 2 detects a signal, the movement towards the sickbed is stopped; the conveyor belt assembly is then activated (reversed) to transfer the patient to the medical care bed. When the patient has been completely transferred to the hospital bed, the conveyor assembly is stopped and the lifting legs 12 then lift the bed plate 2 off the bed and out through the drive wheels 52. The transfer process can be operated by a remote controller or automatically carried out according to a preset program.

While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
