Background

The scanning sickbed is a key component for carrying out human body scanning by matching with medical imaging equipment, such as a scanning sickbed matched with CT (Computed Tomography, electronic computer tomography) and MR (Magnetic Resonance, magnetic resonance imaging). The patient lies on the scanning patient bed, loads the scanning protocols of different medical equipment, and scans the positioning and specific functions of the human body. However, referring to the related art, for example, CN114680914 a-a PET-CT scanning device, CN 111436963B-a self-calibration method and scanning system of a head moving CT detector, it can be found that the scanning sickbed in the scanning device or system in the prior art can only move along the axial direction of the whole device and system, so that the to-be-detected part of the patient is moved to the vicinity of the position corresponding to the scanning center. However, for a severe patient needing image scanning, the patient does not have the mobility, and can only lie on the nursing bed, and the patient needs to be assisted by other people to be transported from the nursing bed to the scanning patient bed. In the process of carrying, firstly, the nursing bed is likely to collide with the scanning sickbed, so that the problems of collision on the appearance and the function of the scanning sickbed are caused; secondly, carrying at least two persons are required to pull the patient bed sheet, and the patient is lifted to the scanning patient bed, so that the carried person wastes time and labor, and in the process, secondary injury to the patient with serious symptoms is possibly caused; meanwhile, due to narrow space of a scanning room, a carrier often steps on the lifting and moving pedals of the sickbed by mistake, so that the sickbed suddenly shakes, and the carrier is dangerous. Therefore, when the image scanning is required to be carried out on the patient with the severe symptoms, the patient with the severe symptoms is easy to cause secondary injury, and the scanning sickbed is easy to collide and damage; and at the same time makes the carrier time consuming and laborious and unsafe.

An embodiment of the present utility model provides a scanning hospital bed comprising a support frame 100, a first bed board 200, a second bed board 300, and a first transmission assembly 400. The first bed board 200 is connected with the support frame 100; the second bed plate 300 is in sliding connection with the first bed plate 200; the first transmission assembly 400 is in transmission connection with the second bed board 300, and the first transmission assembly 400 can drive the second bed board 300 to approach or depart from the first bed board 200.

Specifically, the first transmission assembly 400 drives the second bed board 300 to approach or separate from the first bed board 200 along the width direction of the scanning bed, that is, the xx' direction in fig. 1 and 2.

When the patient is scanned by the scanning sickbed, the patient carrying the nursing bed is firstly moved into the scanning room, and the first transmission assembly 400 drives the second bed plate 300 to be far away from the first bed plate 200, so that the second bed plate 300 is close to and abutted against the nursing bed carrying the patient. At this time, the patient can turn over from the nursing bed to the second bed plate 300 by turning over itself or turning over with the assistance of other people. Then, the first transmission assembly 400 drives the second bed board 300 to approach the first bed board 200 until the first bed board moves to the initial position, so as to scan the image of the patient. Since the patient is moved from the nursing bed to the scanning patient bed by moving the second bed plate 300 and the patient is turned over by itself or by others, no other assistance is required to transport the patient from the nursing bed to the scanning patient bed. The whole process not only reduces the possibility of secondary injury to the patient with serious symptoms in the carrying process; the possibility of collision of the nursing bed and the scanning sickbed with a large impact force can be reduced, so that the problems caused by collision in appearance and function of the scanning sickbed are reduced; meanwhile, the possibility that the carrier steps on the lifting and moving pedals of the scanning sickbed by mistake is reduced, and sudden shaking of the scanning sickbed is reduced, so that the carrier is dangerous. When the patient is scanned by the scanning sickbed, the whole process is safe, time-saving and labor-saving.

It should be noted that, the first transmission assembly 400 may be a worm gear assembly that is matched with each other, or may be a rack and pinion assembly that is matched with each other, or may be a slide rail and slide block assembly, a sprocket and chain assembly, a pulley assembly, or a screw transmission assembly that is matched with each other, which is not particularly limited, as long as the function of driving the second bed board 300 to approach or separate from the first bed board 200 can be achieved.

The following describes the structure of the scanning hospital bed in detail. Referring to fig. 7 and 8, fig. 7 is a schematic diagram illustrating the connection between the second bed board 300 and the second transmission assembly 700 shown in fig. 2; fig. 8 shows a schematic view of the second transmission assembly 700 shown in fig. 7.

Referring to fig. 6, a first transmission assembly 400 of a scanning sickbed according to an embodiment of the present utility model includes a first driving member 410, a first worm wheel 420 and a first worm 430; the first driving piece 410 is installed on the first bed board 200, the first worm wheel 420 is sleeved and fixed on the power output end of the first driving piece 410, the first worm 430 is in transmission connection with the first worm wheel 420, and one end of the first worm 430 is connected with the second bed board 300; when the first driving member 410 drives the first worm wheel 420 to rotate around its own rotation axis, the first worm 430 can be driven to move along its own extending direction, specifically, the extending direction of the first worm 430 is xx' in fig. 6, so that the second bed plate 300 is close to or far away from the first bed plate 200. The second deck 300 is moved closer to or farther from the first deck 200 by the co-operation of the first driver 410, the first worm wheel 420, and the first worm 430. In one particular embodiment, the second deck 300 is spaced apart from the first deck 200 when the power output shaft of the first drive member 410 rotates clockwise, and the second deck 300 is positioned closer to the first deck 200 when the power output shaft of the first drive member 410 rotates counterclockwise. Of course, in other embodiments, the rotation direction may be opposite to the rotation direction, which is not particularly limited. Specifically, the first driving member 410 may be a motor or a telescopic cylinder.

Referring to fig. 3-6, the scanning sickbed according to an embodiment of the present utility model further includes a connecting plate 330, wherein the connecting plate 330 is connected to one end of the first worm 430 through a second bearing (not shown), and the connecting plate 330 is slidably connected to the second bed board 300. When it is desired to move the patient onto the second deck 300, the second deck 300 is now required to be moved away from the first deck 200. The user first slides the second deck 300 relative to the connection plate 330, so that the second deck 300 slides from the position shown in fig. 3 to the first preset position shown in fig. 4. Then, the first driving member 410 drives the first worm wheel 420 to rotate around its own rotation axis, and when the first driving member 410 drives the first worm wheel 420 to rotate around its own rotation axis and further drives the first worm 430 to rotate and move along its own extending direction, the connecting plate 330 and the second bed plate 300 can only move along the extending direction of the first worm 430 due to the effect of the second bearing, but not rotate synchronously with the first worm 430.

Referring to fig. 3-6, the first transmission assembly 400 of the scanning sickbed according to an embodiment of the present utility model further includes a second driving member 440, a second worm wheel (not shown) and a second worm 450; the second driving piece 440 is installed on the support frame 100, the second worm wheel sleeve is fixed at the power output end of the second driving piece 440, and the second worm 450 is in transmission connection with the second worm wheel; the second driving member 440 can drive the second worm 450 to move when driving the second worm wheel to rotate around its own rotation axis. Specifically, the extending direction of the second worm 450 is parallel to the extending direction of the first worm 430, and the extending direction of the second worm 450 is xx' in fig. 6. When the first worm 430 moves to the second preset position along the self extending direction, the first worm 430 is separated from the first worm wheel 420, and the first worm 430 is detachably connected with the second worm 450, so that when the second worm 450 moves along the self extending direction, the first worm 430 can be driven to move along the extending direction of the second worm 450. Specifically, the second driving member 440 may be a motor or a telescopic cylinder.

Because the first transmission assembly 400 further includes the second driving member 440, the second worm wheel and the second worm 450, and when the first worm 430 moves to the second preset position along the self extending direction, the first worm 430 is separated from the first worm wheel 420, and the first worm 430 is detachably connected with the second worm 450, so that when the second worm 450 moves along the self extending direction, the first worm 430 can be driven to move along the extending direction of the second worm 450, the moving stroke of the second bed board 300 relative to the first bed board 200 is increased, and the second bed board 300 is more easily abutted to nursing beds with different distances from the first bed board 200, and the adaptability of the whole hospital bed is stronger.

Referring to fig. 3, the scanning sickbed provided in an embodiment of the present utility model further includes a connection assembly; the connection assembly includes a first connection 510, a first bearing (not shown), and a second connection 520; the first connecting piece 510 is fixedly connected to one end of the first worm 430, specifically, the first connecting piece 510 is fixedly connected to one end of the first worm 430 facing away from the connecting plate 330; the inner ring of the first bearing is sleeved and fixedly connected to one end of the second worm 450, and the second connecting piece 520 is fixedly connected to the outer ring of the first bearing; when the first worm 430 moves to the second preset position along its own extending direction, the first connection member 510 is detachably connected to the second connection member 520.

When the first worm 430 moves to the second preset position along the extending direction of the first worm 430, the first connecting piece 510 is detachably connected with the second connecting piece 520, and the second worm 450 rotates around the rotation axis of the second worm 450, the second connecting piece 520 does not synchronously rotate with the second worm 450 due to the effect of the first bearing, and the first connecting piece 510 connected with the second connecting piece 520 does not rotate, so that the first worm 430 is driven by the second worm 450 to rotate and only moves along the extending direction of the second worm 450.

It should be noted that, the detachable connection manner between the first connector 510 and the second connector 520 may be realized by inserting and separating the grooves and the protrusions of the pure mechanical structure from each other. For example, the first connection member 510 is configured with a protrusion, and the second connection member 520 is configured with a groove, and when the first worm 430 moves to the second preset position shown in fig. 5 along its own extending direction, the protrusion is extended into the groove, so that the first connection member 510 and the second connection member 520 are connected. When the second bed board 300 is close to the first bed board 200 and moves from the second preset position shown in fig. 5 to the position shown in fig. 4, the first driving member 410 rotates in the opposite direction, so as to drive the first worm 430 to move from x to x' in fig. 4 and 5, the protrusion and the groove are naturally separated, and the first connecting member 510 and the second connecting member 520 are separated.

Of course, in other embodiments, the first connection member 510 and the second connection member 520 can be detachably connected to each other by a sensor, an electromagnet, and a permanent magnet. For example, a first sensor and an electromagnet electrically connected to each other are mounted on the first connection member 510, and a second sensor and a permanent magnet are mounted on the second connection member 520. When the first worm 430 drives the first connecting piece 510 to move to the corresponding preset position, the first sensor can identify the second sensor at this time, and control the electromagnet to be electrified, so that the electromagnet generates magnetism and can attract with the permanent magnet, and further the first connecting piece 510 and the second connecting piece 520 are connected. When the first connecting piece 510 and the second connecting piece 520 are required to be separated at the corresponding other preset position, the electromagnet is controlled to be powered off through the first sensor, so that the magnetism of the electromagnet disappears, the electromagnet is separated from the permanent magnet, and the separation of the first connecting piece and the second connecting piece is realized.

Referring to fig. 2, the scanning hospital bed according to an embodiment of the present utility model further includes a guide assembly 600, where the guide assembly 600 includes a guide rod 610, a first guide sleeve 620 and a second guide sleeve 630; the first guide sleeve 620 is mounted on the first bed plate 200, and the second guide sleeve 630 is mounted on the second bed plate 300; one end of the guide rod 610 extends into the first guide sleeve 620 and is fixedly connected with the first guide sleeve 620, and the other end of the guide rod 610 penetrates into the second guide sleeve 630 and is in sliding connection with the second guide sleeve 630; when the second bed plate 300 approaches or moves away from the first bed plate 200, the second guide sleeve 630 slides relative to the guide rod 610.

Through setting up guide arm 610 and uide bushing for when second bed board 300 is close to or keeps away from relative first bed board 200, second bed board 300 removes along the extending direction of guide arm 610, makes the direction of movement of second bed board 300 comparatively stable, avoids second bed board 300 to take place the condition of rocking from top to bottom, and whole scanning sick bed is in the use, and the motion is more steady.

Referring to fig. 2, in the scanning sickbed according to an embodiment of the utility model, the number of the guide assemblies 600 is at least two, and the at least two guide assemblies 600 are arranged at intervals along the length direction of the first bed board 200, specifically, the length direction of the first bed board 200 is yy' direction in fig. 2. By arranging at least two groups of guide assemblies 600, the moving process of the second bed plate 300 relative to the first bed plate 200 is more stable under the cooperative guide action of a plurality of guide assemblies 600. In one specific embodiment, the number of the guide assemblies 600 is two, but in other embodiments, the number of the guide assemblies 600 may be three, four, five, or the like, which is not limited in particular.

Referring to fig. 7, a second bed plate 300 of a scanning sickbed according to an embodiment of the present utility model includes a first rotating plate 310 and a second rotating plate 320 rotatably connected to each other. Since the second couch 300 includes the first rotation plate 310 and the second rotation plate 320 rotatably connected to each other, when the head of the patient is scanned, the first rotation plate 310 is rotated with respect to the second rotation plate 320 or the second rotation plate 320 is rotated with respect to the first rotation plate 310 in order to obtain a better scanned image. Compared with the inclination of a frame or the digital inclination, the inclination mode is simpler and more convenient, the manufacturing cost of the whole medical imaging equipment is lower, and the economic benefit is better; the patient can be prevented from receiving more radiation dose, the damage to the patient is smaller, and the loss to the bulb tube is smaller; meanwhile, the fear of the patient to the inclination of the stand can be reduced, and the design is more humanized. It should be noted that, the rotation angle of the first rotation plate 310 relative to the second rotation plate 320 may be adjusted according to the requirement of the scanning protocol, which is not limited in particular.

It should be noted that, the gantry tilt refers to the mechanical tilt of the gantry ±30°, so as to complete the head scan to obtain a clear head image, but a high requirement is put on the mechanical structural stability of the gantry, and the failure of the gantry may cause a safety problem for the patient to be scanned. The digital tilting means that the stand does not have a mechanical tilting function, but is realized in a software mode, but the scanning range and the dosage are increased, the service life of the bulb tube is greatly damaged, and the radiation dosage received by a patient is more.

In one specific embodiment, the number of the first rotating plates 310 is two, and the two first rotating plates 310 are respectively disposed on two sides of the second rotating plate 320 along the yy ' direction in fig. 2, so that no matter where the patient is located on the second bed plate 300, the patient's head does not need to be adjusted, and the patient's head can be tilted, which is more convenient.
