An embodiment of the present disclosure further provides a radiotherapy treatment couch, including the at least one protection apparatus.
As can be seen from the above technical solution, the protection apparatus of the embodiment of the present disclosure includes: a protection panel and a status control mechanism connected to the protection panel, the protection panel being located in a to-be-protected area of the treatment couch and being perpendicular to a couch top of the treatment couch when in a use position, and the status control mechanism be configured to fix the protection panel to the use position or adjust the protection panel to a lay-down position. In the embodiments of the present disclosure, the status control mechanism may adjust the protection panel in the use position, or in the lay-down position, so that the protection panel may protect a patient when in the use position, and the protection panel may not hinder a movement of the patient when in the lay-down position.

In the embodiment of the present disclosure, when the status adjustment part 121 is in the first position, an upward force is applied by lifting the lifting handle 1211, thereby driving the at least one movement link 1212 connected to the lifting handle 1211 to move upward, so that the at least one movement link 1212 moves from the first position to the second position, and the status of the protection panel is switched from the use position to the lay-down position.
In the embodiment of the present disclosure, when the status adjustment part 121 is in the second position, a downward force is applied by pressing the lifting handle 1211, thereby driving the at least one movement link 1212 connected to the lifting handle to move downward, so that the at least one movement link 1212 moves from the second position to the first position, and the status of the protection panel is switched from the lay-down position to the use position.
Specifically, the first fixing part 122 is a fixing groove, the fixing groove is located on a side of the treatment couch where the to-be-protected area of the treatment couch is located, and the fixing groove corresponds to the movement link 1212, to receive the movement link 1212 such that the movement link moves through the fixing groove.

Specifically, referring to
In the embodiment of the present disclosure, the fastening lock used by the second fixing part 123 facilitates better fixing of the movement link 1212 to the first position, which is convenient for operation and subsequent maintenance.
Specifically, a number of the movement link 1212 is two, and the two movement links 1212 are respectively located at two ends of the lifting handle 1211. Therefore, it is convenient for the upward or downward force applied by the lifting handle 1211 to be well transmitted to the movement link 1212 and drive the movement link 1212 to move.
In yet another specific embodiment of the present disclosure, referring to
The third fixing part 124 may make the protection panel 11 realize status switching more stably.
For example, the third fixing part 124 is a hinge that is respectively fixed to the protection panel and the to-be-protected area of the treatment couch by two ends of a screw.
Referring to
A movement range of the status adjustment part 121 is between a lower edge of the protection panel 11 close to the couch top 21 of the treatment couch to and an upper edge of the protection panel 11 away from the couch top 21 of the treatment couch.
Referring to
The at least one protection apparatus 1 is disposed on at least one side surface of the couch top 21 of the radiotherapy treatment couch.
For example, there are two protection apparatuses 1 and they are respectively located on both sides of the couch top 21 of the treatment couch. As another example, there are three protection apparatuses 1, and they include located on both sides of the couch top 21 of the treatment couch respectively, and on a side surface of the patient's head or feet of the couch top 21 of the treatment couch.
In the embodiment of the present disclosure, the status control mechanism may adjust the protection panel to be in the use position or the lay-down position, so that the protection panel may protect a patient when the protection panel is in the use position, and the protection panel may not hinder a movement of the patient when in the lay-down position.
In a specific embodiment of the present disclosure, referring to
Therefore, in the embodiment of the present disclosure, the status information of the protection panel may be displayed through the display mechanism, thereby preventing medical personnel from being able to understand the status of the protection panel 11 by observing the treatment couch.
In another specific embodiment of the present disclosure, the sensing mechanism 61 is further configured to send the status information of the protection panel 11 to a control system (not shown in the figure) of the radiotherapy equipment, and the control system (not shown in the figure) controls the radiotherapy equipment to perform radiotherapy based on the status information of the protection panel.
Specifically, the control system may control the movement of the radiotherapy couch and/or an activation of a radiation source apparatus (not shown in the figure) based on the status information.
For example, when the protection panel 11 is in the use position, the control system controls the radiotherapy couch to move, and/or when the protection panel 11 is in the use position, the control system controls an open source operation of the radiation source apparatus. When the protection panel 11 is in the lay-down position, the control system controls the radiotherapy couch to be unable to move, and/or, when the protection panel 11 is in the lay-down position, the control system controls the radiation source apparatus to be in a source off status.
The treating physician activates the radiotherapy equipment for radiotherapy, and if the protection panel is in the lay-down position, the display mechanism may display a warning for the status of the protection panel, where the warning may be provided by an indicator light of the treatment couch or the warning may be displayed on the display screen. In addition, when the protection panel is in the lay-down position, the control system controls the treatment couch not to move to avoid accidents. Or, when the protection panel is in the lay-down position, the control system controls the radiation source apparatus to turn off the source, and radiotherapy cannot be performed.
The display mechanism may be located on the radiotherapy equipment as shown in
As another example, when the protection panel is in a working status or the lay-down position, the indication apparatus may also give a sound alarm to remind the treating physician to adjust the status of the protection panel.
Therefore, the embodiment of the present disclosure may control the status of the radiotherapy couch and/or the radiation source apparatus based on the status information of the protection panel 11, avoiding that since the protection panel 11 cannot protect the patient, and the operation of the radiotherapy couch and/or the radiation source apparatus causes the patient to slip off or suffer other injuries to cause the occurrence of medical malpractice.
In another specific embodiment of the present disclosure, referring to
The present disclosure senses the status of the protection panel 11 through the sensor 611 and the control circuit 612 connected to the sensor 611, thereby realizing monitoring of a relative movement between the protection panel 11 of the treatment couch and the status control mechanism 12 through signal sensing and conversion, thereby realizing an acquisition of the status of the protection panel 11. The implementation of the present disclosure is simple in design and easy to maintain.
Specifically, the sensor is a non-contact sensor or a contact sensor.
The sensor is a non-contact sensor such as a displacement sensor. The non-contact sensor may sense the status of the protection panel 11 without contact, and its installation position is more flexible.
The sensor is a contact sensor, such as a proximity switch. Two contact ends of the contact sensor are respectively installed on any two contact ends of the radiotherapy couch, the protection panel 11, and the status control mechanism of the protection panel that can sense the status of the protection panel.
Since the contact sensor senses the status of the protection panel 11 through contact, its sensed accuracy is higher.
