Technical Field

The utility model relates to the technical field of medical equipment, especially relate to portable sick bed.

Background

Medical imaging equipment (such as MRI, CT, etc.) requires a patient bed as a carrier to carry the patient into a scanning area. The hospital bed in the conventional medical imaging system is fixed. When a patient with first aid or inconvenient action is encountered, the patient is influenced in comfort and even secondary damage in the transfer process is caused due to the fact that a carrier sickbed for bearing the patient needs to be frequently replaced, and therefore the problem can be well solved through the movable sickbed. When the patient bed is docked with the gantry of the medical imaging device, the patient bed is usually manually pushed to dock the patient bed. Generally, the movable hospital bed has a heavy weight and needs to load a patient, so the movable hospital bed and the patient have a heavy weight, and therefore, a large force needs to be applied to the hospital bed in order to push the hospital bed. In addition, in order to ensure reliable docking between the patient bed and the scanning frame of the medical imaging device, a larger docking force is required to achieve the docking, so that the movable patient bed is collided to a greater extent when docking is completed, and further, the problems of large noise, easy damage to the docking piece and the like are caused.

Referring to fig. 1, an embodiment of the present application provides a movable hospital bed 100. The movable patient bed 100 is used to dock with the scanning gantry 10 of the medical imaging apparatus. The medical imaging devices are, for example, MRI, CT, PET-MR, CT-RT, etc. Referring again to fig. 2 and 3, the movable bed 100 includes: a hospital bed body 110, a docking structure 120, a first driving assembly 130, a first triggering device 140 and a control device (not shown). The docking structure 120 is connected to the patient bed body 110. The first driving assembly 130 is disposed on the patient bed body 110 and is used for driving the patient bed body 110 to move, so that the docking structure 120 can dock with the matching structure 11 on the scanning gantry 10. The first triggering device 140 is disposed on the docking structure 120 or the mating structure 11 of the scan gantry 10. The first triggering device 140 is used for generating a first triggering signal. The control device is disposed on the hospital bed body 110 and configured to receive the first trigger signal and control the first driving assembly 130 to stop driving the hospital bed body 110 according to the first trigger signal, so that the hospital bed body 110 can move to the fully docked position and stop moving.

Specifically, referring to fig. 1, when the movable bed 100 is used for docking with the scanning gantry 10, the docking structure 120 is located at one end of the movable bed 100 close to the scanning gantry 10, and the matching structure 11 is located at one end of the scanning gantry 10 close to the movable bed 100.

The movable bed 100 includes a bed body 110, a support frame 170 supporting the bed body 110, and a traveling wheel 160 for driving the support frame 170 to move.

The first driving assembly 130 may include a motor, and the motor may drive the traveling wheel 160 to rotate, so that the traveling wheel 160 drives the supporting frame 170 to move, and the supporting frame 170 drives the bed body 110 to move, so that the bed body 110 may move toward the scanning frame 10. In one embodiment, the motor may be a hub motor and is mounted to the hub of the traveling wheel 160, so that the traveling wheel 160 can be directly driven to rotate without providing an additional transmission mechanism.

Referring to fig. 2 and fig. 3, the docking structure 120 is fixedly connected to one end of the supporting frame 170. The docking structure 120 includes a docking body 121 and a guide post 122. The docking body 121 is fixedly connected to one end of the supporting frame 170. The guide post 122 protrudes from one end of the docking body 121. One end of the fitting structure 11 near the hospital bed body 110 is provided with a guiding hole (not shown), and the guiding hole can be matched with the guiding column 122. Referring to fig. 4 and 5, when the patient bed body 110 moves toward the scanning gantry 10, the guide post 122 can be gradually inserted into the guide hole, so that the docking structure 120 and the mating structure 11 are docked.

The first triggering device 140 may be a photoelectric sensor or an infrared sensor or a distance sensor, etc. The control device can be a controller, such as a PLC controller, and also can be a singlechip, a microprocessor and the like. The first triggering device 140 is in communication with the control device. The control device may be disposed on the hospital bed body 110.

Taking the first triggering device 140 as an example of a photoelectric sensor, in this embodiment, the photoelectric sensor may be disposed on the docking structure 120, and when the patient bed body 110 moves toward the scanning gantry 10, the photoelectric sensor and the docking structure 120 move toward the scanning gantry 10 synchronously. Referring to fig. 4 and 5, when the sickbed body 110 moves to the first predetermined position, the docking structure 120 is in a state to be docked with the mating structure 11, that is, the first predetermined position is a position to be docked between the sickbed body 110 and the mating structure 11. Referring to fig. 5, when the sickbed body 110 moves to the first predetermined position, the photoelectric sensor just moves to the end of the matching structure 11 close to the sickbed body 110, so that the photoelectric sensor can be triggered by the matching structure 11 and generates a first trigger signal, at this time, the control device controls the first driving assembly 130 to stop driving the sickbed body 110 according to the first trigger signal, and the sickbed body 110 decelerates until stopping.

At the moment when the first driving assembly 130 stops driving the bed body 110, the bed body 110 is in the first position. In the process of decelerating the patient bed body 110, the patient bed body 110 will continue to move a certain distance in the direction approaching the scanning gantry 10 until the patient bed body 110 stops moving, and the patient bed body 110 moves to the second position. When the patient bed body 110 moves to the second position, the docking structure 120 can automatically complete docking with the matching structure 11, that is, the second position is a position when the patient bed body 110 is fully docked with the scanning gantry 10, that is, a fully docked position. Since the patient bed body 110 stops moving when in the second position, the docking structure 120 stops moving automatically when the docking structure 120 is docked with the mating structure 11.

In other embodiments, the first triggering device 140 can also be disposed on the patient bed body 110 or the supporting frame 170. In addition, the first triggering device 140 may also be disposed on the matching structure 11, and when the hospital bed body 110 moves to the first predetermined position, the first triggering device 140 can also generate the first triggering signal.

It can be understood that when the acceleration of the patient bed body 110 is very large during deceleration, the patient bed body 110 stops moving almost instantaneously, and the distance between the first position and the second position is very small, even close to zero.

In the movable hospital bed 100, when the first driving assembly 130 drives the hospital bed body 110 to move toward the scanning gantry 10, the docking structure 120 can dock with the matching structure 11 on the scanning gantry 10. When the patient bed body 110 moves to a first predetermined position in a direction approaching the scanning gantry 10, the first triggering device 140 can generate a first triggering signal. The control device controls the first driving assembly 130 to stop driving the sickbed body 110 according to the first trigger signal. When the first driving assembly 130 stops driving the bed body 110 and the bed body 110 stops moving, the bed body 110 moves from the first position to the second position. When the hospital bed body 110 moves to the second position, the docking structure 120 can automatically complete docking with the mating structure 11. Because the sickbed body 110 stops moving when in the second position, the docking structure 120 stops moving automatically when the docking structure 120 and the matching structure 11 are docked, so that the docking structure 120 does not excessively collide with the matching structure 11 or collide with the matching structure to a small extent when docking is completed, the noise is small, and the docking piece is not easy to damage.

Compared with the prior art, when the butt joint structure 120 and the matching structure 11 are in butt joint, the movable sickbed 100 is not required to be pushed manually, so that the impact noise generated by overlarge manual thrust can be effectively avoided. Moreover, when the docking structure 120 and the matching structure 11 are docked, the docking structure 120 and the hospital bed body 110 stop moving together, so that the docking piece is protected greatly, and the damage rate of the docking piece is reduced.

Referring to fig. 3 and 5, in an embodiment, the docking structure 120 further includes a primary guiding assembly. The primary guide assembly has a guide space. The opening of the guide space is directed towards the scan gantry 10. The guiding space is used for the engagement structure 11 to enter and engage with the engagement structure 11. The end of the primary guide 124 extends beyond the end of the guide post 122 in the direction in which the patient bed body 110 approaches the scanning gantry 10.

As shown in fig. 3 and 5, in the present embodiment, the primary guide assembly includes two primary guide portions 124. The two primary guides 124 are spaced apart in the width direction of the bed body 110, so that a guide space is formed between the two primary guides 124, which is open toward the scanning gantry 10.

Specifically, the primary guide portion 124 is a guide bar. The two guide rods are respectively fixedly connected with one end of the supporting frame 170 close to the scanning frame 10. When the docking structure 120 and the mating structure 11 start to be docked, the primary guide portions 124 move towards the mating structure 11, so that the mating structure 11 passively enters the guide space between the two primary guide portions 124 and fits into the guide space, and the mating structure 11 can define the movement direction of the primary guide portions 124, and the primary guide portions 124 play a role in guiding the movement direction of the docking structure 120.

As can be seen from fig. 3, the end of the primary guide portion 124 extends beyond the end of the guide post 122 along the direction of the patient bed body 110 approaching the scanning gantry 10, so that when the docking structure 120 and the mating structure 11 start to dock, the primary guide portion 124 first docks with the mating structure 11. After the patient bed body 110 moves a distance further toward the scanning gantry 10, a portion of the fitting structure 11 enters the guiding space, and then the guiding post 122 can be inserted into the guiding hole. Therefore, preliminary guidance is performed through the primary guiding assembly, so that when the matching structure 11 is butted with the primary guiding assembly, the guide column 122 is aligned with the guide hole in advance, and the guide column 122 can be smoothly inserted into the guide hole.

Referring to fig. 3 and 5, in one embodiment, the primary guide assembly is provided with a roller 123. During the process of the engagement structure 11 entering the guiding space, the roller 123 is used to roll along the sliding rail 13 on the engagement structure 11.

Specifically, in the present embodiment, a roller 123 is provided on each primary guide portion 124. The roller 123 is disposed below the primary guide 124. The two sides of the mating structure 11 may be provided with a sliding groove, respectively, such that the sliding grooves form a sliding rail 13. The extension direction of the slide rail 13 is along the moving direction of the docking structure 120 when approaching the scan frame 10, i.e. the length direction of the primary guide 124.

When the docking structure 120 and the mating structure 11 start to be docked and the mating structure 11 passively enters the guiding space between the two primary guiding portions 124, the roller 123 is engaged with the sliding rail 13 and rolls along the sliding rail 13, so that the primary guiding portion 124 can be smoothly engaged with the mating structure 11 through the roller 123 and the sliding rail 13.

As shown in fig. 3 and 5, each of the primary guides 124 is sequentially provided with a plurality of rollers 123 along the length direction, so that the docking structure 120 operates stably during docking of the docking structure 120 with the mating structure 11.

It is understood that at least one roller 123 is provided on each primary guide 124. Of course, two, three, etc. rollers 123 may be provided on each primary guide 124.

Referring to fig. 3 and 5, in an embodiment, the first triggering device 140 is disposed on the primary guiding assembly.

Specifically, the first triggering device 140 may be disposed on the primary guide 124. In the present embodiment, two first triggering devices 140 are respectively disposed on the two primary guiding portions 124, and the two first triggering devices 140 are disposed opposite to each other.

In the present embodiment, the first triggering device 140 is a photo sensor. When the patient bed body 110 moves to the first predetermined position, the photoelectric sensor moves to the end of the mating structure 11 close to the patient bed body 110 along with the primary guiding portion 124, so that the photoelectric sensor can be triggered by the mating structure 11 and generate a first trigger signal.

In an embodiment, the moveable bed 100 further comprises a second triggering device 150. The second triggering device 150 is disposed on the docking structure 120. The second trigger device 150 can generate a second trigger signal when the patient bed body 110 is located at a second predetermined position relative to the scanning gantry 10. The control device is further configured to control the first driving assembly 130 to start driving the patient bed body 110 to move toward the scanning gantry 10 according to the second trigger signal.

Specifically, the second triggering device 150 may be a photoelectric sensor or an infrared sensor or a distance sensor, etc. The second triggering device 150 is connected in communication with the control device. In this embodiment, the second triggering device 150 may be disposed on the primary guiding portion 124. Two second triggering devices 150 are respectively disposed on the two primary guiding portions 124, and the two second triggering devices 150 are disposed opposite to each other.

For example, the second triggering device 150 is a photoelectric sensor, and the second triggering device 150 can be disposed at an end of the primary guide assembly near the scanning gantry 10. The sickbed body 110 can be pushed to the second predetermined position by a manual pushing mode. Referring to fig. 2 and fig. 3, when the sickbed body 110 is at the second predetermined position, the docking structure 120 is in a state to be docked with the mating structure 11, that is, the second predetermined position is a position to be docked between the sickbed body 110 and the mating structure 11. When the patient bed body 110 is at the second predetermined position, the second triggering device 150 just reaches the end of the mating structure 11 close to the patient bed body 110, so that the second triggering device 150 can be triggered by the mating structure 11 and generate a second triggering signal. At this time, the control device controls the first driving assembly 130 to start driving the sickbed body 110 to move according to the second trigger signal until the docking structure 120 and the matching structure 11 complete docking. It can be seen that, in the whole process from the start of docking to the completion of docking of the docking structure 120 and the mating structure 11, the second trigger device 150 triggers the first driving assembly 130 to drive the sickbed body 110 to start moving, and the first trigger device 140 triggers the first driving assembly 130 to drive the sickbed body 110 to stop moving, so that the whole process from the start of docking to the completion of docking of the docking structure 120 and the mating structure 11 does not need manual pushing, manpower is saved, and collision due to over-large pushing force or small collision degree is avoided, and further, the noise is small, and the docking piece is not easy to damage.

In other embodiments, when the second triggering device 150 is a distance sensor, it can be set in the control device that when there is a predetermined distance between the docking structure 120 and the mating structure 11, the second triggering device 150 generates the second triggering signal, and the first driving assembly 130 starts to drive the bed body 110 to move. It will be appreciated that in this case, the docking structure 120 has not yet begun to dock with the mating structure 11 when the bed body 110 is in the second predetermined position.

In other embodiments, the second triggering device 150 can also be disposed on the patient bed body 110 or the supporting frame 170. In addition, the second triggering device 150 may also be disposed on the matching structure 11, and when the hospital bed body 110 moves to the second predetermined position, the second triggering device 150 can also generate the second triggering signal.

In the present embodiment, the second triggering device 150 and the first triggering device 140 are both photosensors. The second triggering device 150 can be disposed at a side of the first triggering device 140 close to the scan gantry 10, so that when the second triggering device 150 triggers the first driving assembly 130 to start driving the bed body 110 to move, the docking structure 120 starts docking with the mating structure 11. When the docking structure 120 is about to be completely docked with the mating structure 11, the first triggering device 140 can just trigger the first driving assembly 130 to stop driving.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
