[0002] Mobile critical care unit medical vehicles generally integrate a consultation room and a medical cabin. The medical cabin is a long, narrow space equipped with a bed and various medical equipment. To facilitate patient transfer, mobile critical care unit medical vehicles are equipped with a lifting mechanism at the door. This lifting mechanism can lift and lower a wheelchair or stretcher to allow the patient to enter the vehicle. However, when using a stretcher to transfer the patient into the vehicle, the stretcher entering laterally needs to be turned and moved to the side of the bed to transfer the patient to the bed. Because the stretcher occupies a large amount of space, it is difficult to change direction or move the stretcher within the limited space of the vehicle, which brings certain difficulties to the transfer of the patient between the stretcher and the bed in the vehicle. At the same time, in addition to the bed, the medical cabin in the vehicle is also equipped with a variety of medical equipment. During treatment or nursing, sufficient operating space needs to be reserved on both sides of the bed to facilitate medical staff to carry out treatment or other nursing work.

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terminology used in the specification of the present application is only for the purpose of describing specific embodiments and is not intended to limit the present application.

[0036] Example 1

[0037] Referring to Figures 1-5 The embodiment discloses a mobile sickbed of a mobile intensive care unit medical vehicle, which comprises a bed surface, a bed frame 1 and an adjusting mechanism for adjusting the position of the bed frame 1. The bed surface is arranged on the top surface of the bed frame 1, and the adjusting mechanism is arranged below the bed frame 1.

[0038] The adjusting mechanism comprises a longitudinal drive mechanism 2 for driving the bed frame 1 to move longitudinally and a lateral drive mechanism 3 for driving the bed frame 1 to move laterally. The length of the bed frame 1 extends longitudinally, and the two side surfaces of the bed frame 1 in the longitudinal direction are inclined inward from top to bottom to form a trapezoidal support with a lateral direction profile of upper width and lower narrowness.

[0039] Further, the bed frame 1 comprises a bottom frame 101 and two support frames; the two support frames are respectively arranged at the longitudinal ends of the bottom frame 101; the lateral direction profile of the bottom frame 101 is trapezoidal, which is wide at the top and narrow at the bottom; one end of each of the two support frames is connected to the bottom frame 101, and the other end extends upward. By arranging such a bed frame 1 structure, the structure is greatly simplified, and the support force on the bed surface is ensured by the two end support frames; at the same time, referring to Figures 2-4 Such a structure can leave a certain space between the bottom frame 101 and the bed surface, so that the space below the bed surface is more sufficient, further reducing the influence on the movement and operation of medical staff.

[0040] Further, each of the support frames comprises two support rods 102, which are respectively arranged at the corners of the bottom frame 101, and the support rods 102 extend obliquely outward and upward. Such a support frame can be conveniently connected to the bed surface, ensuring the stability of the bed surface, while being combined with the bottom frame 101.

[0041] Further, the longitudinal driving mechanism 2 extends along the longitudinal direction (i.e. the length direction of the bed frame 1 and the bed surface in this embodiment) of the bed frame 1 and the bed surface; and the width of the longitudinal driving mechanism 2 is narrower than that of the bed surface. Further, in this embodiment, the width of the longitudinal driving mechanism 2 is close to that of the bottom frame 101, avoiding that the width of the longitudinal driving mechanism 2 is too large and occupies too much space.

[0042] Further, since the medical cabin is a long and narrow space, preferably, the adjusting mechanism is also of a structure that is large at the top and small at the bottom, the wider transverse driving mechanism 3 is arranged above the longitudinal driving mechanism 2, and the narrower longitudinal driving mechanism 2 is fixed to the floor of the cabin, ensuring the maximum floor space on both sides of the hospital bed, to further reduce the movement obstacles of medical staff. The bed frame 1 is arranged on the transverse driving mechanism 3. The transverse driving mechanism 3 is connected to the power output of the longitudinal driving mechanism 2 through a longitudinal moving frame 4; the bed frame 1 is connected to the power output of the transverse driving mechanism 3 through a transverse moving frame 5.

[0043] Further, the longitudinal driving mechanism 2 comprises a base 202 and a longitudinal electric cylinder 201 arranged on the base 202; the telescopic rod of the longitudinal electric cylinder 201 is connected to the longitudinal moving frame 4; the longitudinal moving frame 4 is arranged on the base 202 and can move longitudinally. In this embodiment, a connecting block 205 is arranged on the telescopic rod, which is connected to the bottom surface of the longitudinal moving frame 4.

[0044] Further, the longitudinal moving frame 4 is provided with a longitudinal guide assembly between the base 202; the longitudinal guide assembly comprises a longitudinal guide rail 203 and a longitudinal sliding block 204, the longitudinal guide rail 203 is fixedly arranged on the base 202, and the longitudinal sliding block 204 is fixedly arranged on the bottom surface of the longitudinal moving frame 4, and the longitudinal sliding block 204 and the longitudinal guide rail 203 are in sliding fit with each other.

[0045] Further, the longitudinal guide assembly in the embodiment is provided with two longitudinal guide assemblies, which is beneficial to improve the moving stability of the longitudinal moving frame 4. Meanwhile, the longitudinal electric cylinder 201 is arranged between the two longitudinal guide assemblies, so that the whole structure is more compact and the space is reduced. In addition, the longitudinal electric cylinder 201 in the embodiment can also adopt other driving modes in the prior art, such as motor and screw transmission, cylinder, motor and belt transmission, etc.

[0046] Further, the chassis 101 and the transverse moving frame 5 are provided with a mounting space, and the transverse driving mechanism 3 is located in the mounting space; the transverse moving frame 5 is arranged on the longitudinal moving frame 4 and can move transversely. The transverse driving mechanism 3 comprises a transverse motor 301, a transmission assembly and a screw rod assembly; the transverse motor 301 is fixedly connected to the bottom surface of the chassis 101, the transmission assembly comprises a synchronous belt 308, a driving wheel 307 and a driven wheel 303, and the screw rod assembly comprises a screw rod 306 and a nut block 305; the nut block 305 is fixedly connected to the longitudinal moving frame 4, the screw rod 306 is matched with the nut block 305, the driven wheel 303 is connected with the screw rod 306, the end of the screw rod 306 is rotatably connected with the transverse moving frame 5, the driving wheel 307 is connected with the main shaft of the transverse motor 301, and the synchronous belt 308 is wound between the driving wheel 307 and the driven wheel 303. When the hospital bed is transversely adjusted, the transverse motor 301 is started, the screw rod 306 is rotated by the transmission assembly, the transverse displacement occurs between the screw rod 306 and the nut block 305, so as to drive the transverse moving frame 5 to move synchronously by the screw rod 306, and the position adjustment in the transverse direction is realized. In addition, the transmission assembly of the embodiment can also adopt the gear chain mode, and the specific implementation mode can be referred to the prior art.

[0047] Further, the transverse moving frame 5 and the longitudinal moving frame 4 are provided with a transverse guide assembly; the transverse guide assembly comprises a transverse guide rail 304 and a transverse sliding block 302, the transverse guide rail 304 is fixedly connected to the bottom surface of the transverse moving frame 5, and the transverse sliding block 302 is fixedly connected to the top surface of the longitudinal moving frame 4; the transverse guide rail 304 and the transverse sliding block 302 are in sliding fit with each other. The transverse guide assembly in the embodiment is provided with two transverse guide assemblies, which are respectively located on both sides of the transverse moving frame 5, so as to form a mounting space in the middle of the transverse moving frame 5.

[0048] Furthermore, the transverse movable frame 5 of this embodiment is roughly rectangular and hollowed out in the middle. A profile 501 is provided at the location corresponding to the transverse guide assembly. A square steel 502 is attached to the profile 501, and the base frame 101 is connected to the square steel 502. This transverse movable frame 5 has a simple and reliable structure and is easy to assemble.

[0049] Furthermore, the driving distance of the longitudinal driving mechanism 2 is longer than the driving distance of the transverse driving mechanism 3. Figures 1-4 As shown, the longitudinal drive mechanism 2 of this embodiment has a long drive distance, allowing ample adjustment space in the longitudinal direction of the bed. Meanwhile, the transverse drive mechanism 3 has a short drive distance, allowing for minor adjustments over short distances. For example, with this design, the bed of this embodiment can be placed near one of the side walls of a vehicle's medical compartment. When surgery is not required or the patient is simply resting, the transverse drive mechanism 3 can be used to adjust the bed frame 1 close to the side wall of the compartment, placing the bed close to the vehicle body and saving space. Furthermore, the longitudinal position can be flexibly adjusted according to the situation, with a long adjustment distance, providing ample adjustment space. When surgery or other medical procedures are required, the transverse drive mechanism 3 adjusts the bed frame 1 away from the inner wall of the vehicle, leaving a certain distance. This distance should primarily be sufficient for medical personnel to pass through, allowing them to move freely around the bed, particularly facilitating surgical procedures.

[0050] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Therefore, any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
