Emergency treatment system and radiotherapy equipment

Abstract

The present application provides an emergency handling system and a radiotherapy device. The emergency handling system includes a target component and a device release component connected to the target component. The target component can send an emergency trigger signal to the device release component, and the device release component can, in response to the emergency trigger signal, release the fixation of the patient positioning device on the patient. Since the device release component in the emergency handling system can, in response to the emergency trigger signal from the target component, automatically release the fixation of the patient positioning device on the patient, when the physical signs of the patient are abnormal during radiotherapy, the patient can be promptly disengaged from the patient positioning device, that is, the patient can promptly get rid of the restraint of the patient positioning device, effectively avoiding the possible risks that the patient positioning device may bring to the patient.

Description

Technical Field

[0001] The present invention relates to the field of radiotherapy, and particularly to an emergency treatment system and a radiotherapy device. Background Art

[0002] Radiotherapy is one of the main means of treating tumors with radiation. The irradiation of radiation can cause cancer cells to necrosis or apoptosis. However, if there is a deviation between the irradiation position of the radiation and the tumor position, it will not only cause the cancer cells to not be effectively killed, but also cause other healthy organs to be irradiated by mistake and damaged. Therefore, during radiotherapy, it is crucial to accurately locate the tumor position.

[0003] In the related art, in order to avoid the deviation between the irradiation position of the radiation and the tumor position caused by the patient's own accidental movement, a patient positioning device is generally used to fix the patient's body position to prevent the patient from accidentally moving. For example, in order to avoid the accidental movement of the patient's head, a head positioning device mask can be used to fix the patient's head.

[0004] However, since the patient cannot be separated from the patient positioning device in time when their physical signs are abnormal, the patient positioning device may bring other risks to the patient. For example, if the patient vomits during radiotherapy, they may suffocate due to the vomit because they cannot be separated from the head positioning device in time. Summary of the Invention

[0042] To make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. Apparently, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0043] Figure 1 is a schematic structural diagram of an emergency handling system provided by an embodiment of the present invention. As Figure 1 shown, the system may include: a target component 10 and a device release component 20.

[0044] In an embodiment of the present invention, the target component 10 may be connected to the device release component 20, and the device release component 20 may be configured to be connected to a patient positioning device ( Figure 1 not shown in the figure). The target component 10 may send an emergency trigger signal to the device release component 20. The device release component 20 may respond to the emergency trigger signal and release the fixation of the patient by the patient positioning device.

[0045] Optionally, the target component 10 may directly send an emergency trigger signal to the device release component 20; or, the target component 10 may also forward the received emergency trigger signal to the device release component 20. In the scenario where the target component 10 directly sends an emergency trigger signal to the device release component 20, when the patient's own physical signs are abnormal (such as wanting to vomit), the patient may trigger the target component 10 to send an emergency trigger signal to the device release component 20 through a preset operation. Alternatively, the target component 10 may actively detect whether the patient's physical signs are abnormal, and when it detects that the patient's physical signs are abnormal, automatically send an emergency trigger signal to the device release component 20.

[0046] The patient positioning device may be a structure for fixing the part of the patient to be treated (such as the head, head and neck, body, etc.) to a patient support device (such as a treatment bed) to prevent the patient from accidentally moving during radiotherapy. And the patient positioning device may include a plurality of movably connected components, that is, the patient positioning device may be composed of a plurality of movably connected components. For example, the patient positioning device may be a positioning device (such as a face mask) for fixing the patient's head or head and neck.

[0047] Correspondingly, when the device release component 20 receives the emergency trigger signal, the device release component 20 may control the patient positioning device to be completely separated from the patient support device to release the fixation of the patient by the patient positioning device. Or, the device release component 20 may control the disconnection at the movably connected components of the patient positioning device to release the fixation of the patient by the patient positioning device. The embodiments of the present invention do not make any limitations in this regard.

[0048] For example, assume that the target component 10 is a device for detecting a patient's vital signs. A certain patient is lying on the patient support device. During the process of tumor treatment, the patient wants to vomit. At this time, the target component 10 can detect that the patient's vital signs are abnormal, and the target component 10 can actively send an emergency trigger signal to the device release component 20 in a timely manner. When the device release component 20 receives this emergency trigger signal, it can control the patient positioning device to disengage from the patient support device in a timely manner, thereby releasing the fixation of the patient positioning device on the patient. Furthermore, the patient can sit up from the patient support device in a timely manner to vomit, effectively avoiding the risk that the patient cannot disengage from the patient positioning device and being suffocated by his vomit.

[0049] In summary, the embodiment of the present invention provides an emergency processing system. The system includes a target component and a device release component connected to the target component. The target component can send an emergency trigger signal to the device release component, and the device release component can respond to the emergency trigger signal to release the fixation of the patient positioning device on the patient. Since the device release component in the emergency processing system can respond to the emergency trigger signal from the target component and automatically release the fixation of the patient positioning device on the patient, when the patient's vital signs are abnormal during radiotherapy, the patient can be disengaged from the patient positioning device in a timely manner, that is, the patient can get rid of the restraint of the patient positioning device in a timely manner, effectively avoiding the possible risks brought by the patient positioning device to the patient.

[0050] Optionally, in the embodiment of the present invention, the target component 10 can also be configured to be connected to the patient support device. Correspondingly, the target component 10 can specifically send an emergency trigger signal to the device release component 20 when it detects that the patient support device is in a preset position.

[0051] Among them, the patient support device can be a structure for supporting the patient during radiotherapy. For example, the patient support device can be a treatment bed or a treatment chair. In the embodiment of the present invention, the treatment bed is taken as an example for illustration. The preset position can be a pre-set position, and at this preset position, the patient will not collide with the radiotherapy device (such as the treatment head in the radiotherapy device or the barrel wall of the treatment roller) included in the radiotherapy equipment due to accidental movement. Therefore, this preset position can also be called a safe position.

[0052] For a radiotherapy device with a small treatment space, if a patient sits up directly from the treatment bed without moving to a safe position, they may collide with the treatment head or the drum wall in the radiotherapy device included in the radiotherapy device. Therefore, by sending an emergency trigger signal to the device release component 20 when the patient support device is detected to be in a preset position (i.e., a safe position), the target component 10 can cause the device release component 20 to release the fixation of the patient positioning device on the patient when the patient support device is in the preset position, further effectively avoiding harm to the patient. Of course, if the treatment space of the radiotherapy device is large enough, the target component 10 does not need to send an emergency trigger signal to the device release component 20 when detecting that the patient support device is in the preset position.

[0053] In an embodiment of the present invention, before sending the emergency trigger signal, the target component 10 can first send a movement control signal for instructing the patient support device to move to the preset position to the patient support device, so as to trigger the patient support device to move to the preset position first. In addition, the target component 10 can also receive a safety indication signal sent after the patient support device moves to the preset position, and determine that the patient support device is in the preset position according to the safety indication signal. Optionally, the movement control signal can also be an emergency trigger signal, that is, the target component 10 can first send an emergency trigger signal to the patient support device, and then send the emergency trigger signal to the device release component 20 when detecting that the patient support device has moved to the preset position.

[0054] That is to say, the target component 10 can not only send a control signal to the patient support device to control the movement of the patient support device, but also receive an indication signal sent by the patient support device to determine whether the patient support device is in the preset position according to the indication signal.

[0055] It should be noted that a positioning component (such as a position sensor) can be provided on the patient support device, and the patient support device can detect its real-time position through the positioning component.

[0056] Optionally, in an embodiment of the present invention, the target component 10 can also be configured to be connected to the radiotherapy device. Correspondingly, the target component 10 can also send an emergency trigger signal to the radiotherapy device before or at the same time as sending the emergency trigger signal to the device release component 20, so as to trigger the radiation source of the radiotherapy device to stop radiotherapy.

[0057] By triggering the radiation source of the radiotherapy device to stop radiotherapy in advance before or at the same time as sending an emergency trigger signal to the device release component 20, that is, before the device release component 20 releases the fixation of the patient positioning device on the patient, the risk that the radiation may irradiate other normal organs of the patient due to a large movement of the patient after the fixation of the patient positioning device on the patient is released can be effectively avoided, that is, further harm to the patient is avoided.

[0058] It should be noted that, in order to effectively avoid harm to the patient, the target component 10 can be configured to be connected to both the radiotherapy device and the patient support device. Before sending an emergency trigger signal to the device release component 20, the target component 10 can first control the radiation source of the radiotherapy device to stop radiotherapy, then control the patient support device to move to a preset position (that is, turn off the source first and then move the bed), and finally send an emergency trigger signal to the device release component 20 to trigger the device release component to release the fixation of the patient positioning device on the patient. Of course, the target component 10 can also control the patient support device to move to a preset position while controlling the radiation source of the radiotherapy device to stop radiotherapy. The embodiments of the present invention do not limit this.

[0059] As an alternative implementation Figure 2 is a schematic structural diagram of another emergency handling system provided by an embodiment of the present invention. As shown in Figure 2 the figure, the target component may include: an emergency signal generator 101.

[0060] The emergency signal generator 101 can be connected to the device release component 20, and the emergency signal generator 101 can send an emergency trigger signal to the device release component 20. That is to say, in the above embodiments, it can be the target component 10 that directly sends an emergency trigger signal to the device release component 20, directly controls the movement of the patient support device, and directly controls the radiation source of the radiotherapy device to stop radiotherapy. By directly sending signals from the target component 10 to each component, the control efficiency can be improved on the premise of effectively avoiding harm to the patient.

[0061] As another alternative implementation Figure 3 is a schematic structural diagram of another emergency handling system provided by an embodiment of the present invention. As shown in Figure 3 the figure, the target component 10 may include: a controller 102 and an emergency signal generator 101.

[0062] The controller 102 can be connected to the emergency signal generator 101 and the device release component 20 respectively. The emergency signal generator 101 can send an emergency trigger signal to the controller 102, and the controller 102 can forward the emergency trigger signal to the device release component 20. That is to say, in the above embodiment, it can be the controller 102 that forwards the emergency trigger signal from the emergency signal generator 101 to the device release component 20 and the radiation source. And it can be the controller 102 that controls the movement of the patient support device.

[0063] By the controller 102 forwarding the signal from the emergency signal generator 101 to each component, the control reliability can be improved on the premise of effectively avoiding harm to the patient.

[0064] It should be noted that an alarm (such as at least one of a buzzer and a light-emitting diode) can also be provided in the target component 10. Correspondingly, the target component 10 can send an alarm signal through the alarm while sending an emergency trigger signal to the device release component, so as to prompt the treating physician to adjust the treatment of the patient in time according to the alarm signal, further ensuring the reliability of the patient treatment.

[0065] Optionally, the controller 102 can be a central processing unit. The emergency signal generator 101 can include at least one of a trigger button (which can also be called an emergency button) and a vital sign detector. The vital sign detector can be used to detect the vital signs of the patient. For example, the vital sign detector can be a wearable device (such as a bracelet) for detecting the vital signs of the patient.

[0066] An optional implementation: when the emergency signal generator 101 includes a trigger button and a vital sign detector, the emergency signal generator 101 can send an emergency trigger signal after receiving a trigger instruction for the trigger button; or, the emergency signal generator 101 can send an emergency trigger signal when detecting that the vital signs of the patient are abnormal. And when the emergency signal generator 101 includes a trigger button, for the convenience of the patient to trigger the trigger button, the patient can hold the emergency signal generator 101. In this way, the reliability of triggering can be ensured on the premise of improving the triggering flexibility. For example, if the patient faints during radiotherapy and fails to trigger the trigger button in time, at this time, the vital sign detection wearable device can actively detect the vital signs of the patient and automatically send an emergency trigger signal, further ensuring the reliability of sending the emergency trigger signal.

[0067] By setting two triggering methods, the triggering flexibility can be improved

[0068] It should be noted that if the emergency signal generator 101 first receives a trigger instruction for the trigger button, the emergency signal generator 101 can perform the operation of sending an emergency trigger signal only according to the trigger instruction, without having to send the emergency trigger signal again when detecting that the patient's vital signs are abnormal subsequently. Similarly, if the emergency signal generator 101 first automatically detects that the patient's vital signs are abnormal, the emergency signal generator 101 can perform the operation of sending an emergency trigger signal only according to the detection result, without having to send the emergency trigger signal again when receiving a trigger instruction for the trigger button subsequently.

[0069] Since there is no sequence between the trigger instruction for the trigger button and the detection of vital signs, through this control method, it is possible to avoid sending the emergency trigger signal multiple times, wasting the processing resources of the emergency signal generator, and it can ensure that the device release component 20 reliably releases the fixation of the patient positioning device on the patient according to the emergency trigger signal.

[0070] Another alternative implementation: When the emergency signal generator 101 includes a vital sign detector, the emergency signal generator 101 can send an emergency trigger signal when detecting that the patient's vital signs are abnormal. That is, the emergency signal generator can be only a vital sign detector for detecting the patient's vital signs.

[0071] Optionally, in the embodiment of the present invention, the patient positioning device may include: at least two movably connected components. The device release component 20 may include: a mechanical and electrical interface provided at the movably connected components of the patient positioning device.

[0072] For example, the patient positioning device may include a patient positioning device body and a clamping member, and the clamping member and the patient positioning device body may be movably connected through a mechanical and electrical interface, that is, the mechanical and electrical interface may be provided at the movable connection of the clamping member and the patient positioning device body. When in use, the mechanical and electrical interface can release the fixation of the patient positioning device on the patient by disconnecting the connection between the clamping member and the patient positioning device body.

[0073] Alternatively, the patient positioning device body may be composed of at least two components, and each component may be movably connected through a mechanical and electrical interface, that is, the mechanical and electrical interface may be provided at the movable connection of at least two components of the patient positioning device body. When in use, the mechanical and electrical interface can release the fixation of the patient positioning device on the patient by disconnecting the connection between at least two components of the patient positioning device body.

[0074] It should be noted that the main body of the patient positioning device can be clamped to the patient support device through the clamping member. For example, the patient support device includes an electromagnetic induction card slot, and the main body of the patient positioning device can be clamped into the electromagnetic induction card slot through the clamping member. Optionally, the clamping member and the electromagnetic induction card slot can be movably connected through a mechanical and electrical interface. During use, the mechanical and electrical interface can disconnect the connection between the clamping member and the electromagnetic induction card slot, so that the entire patient positioning device is disconnected from the patient support device, thereby releasing the fixation of the patient positioning device on the patient.

[0075] It should also be noted that in the embodiments of the present invention, the target component 10, the device release component 20, the patient support device, and the treatment head (including the radiation source) of the radiotherapy device can all be configured with drive devices. Correspondingly, for the above embodiments, their respective drive devices receive or send signals and control their own movements according to the received signals. Optionally, the drive device can include a logic circuit and a corresponding mechanical drive structure.

[0076] In summary, the embodiments of the present invention provide an emergency handling system. The system includes a target component and a device release component connected to the target component. The target component can send an emergency trigger signal to the device release component, and the device release component can respond to the emergency trigger signal to release the fixation of the patient positioning device on the patient. Since the device release component in the emergency handling system can respond to the emergency trigger signal from the target component and automatically release the fixation of the patient positioning device on the patient, when the patient's physical signs are abnormal during radiotherapy, the patient can be promptly detached from the patient positioning device, that is, the patient can promptly get rid of the restraint of the patient positioning device, effectively avoiding the possible risks brought by the patient positioning device to the patient.

[0077] Figure 4 is a schematic structural diagram of a radiotherapy device provided by an embodiment of the present invention. As Figure 4 shown, the radiotherapy device can include a patient positioning device 00, and an Figures 1 to 3 emergency handling system 01 as shown in any one of them. The emergency handling system 01 can be connected to the patient positioning device 00, and the emergency handling system 01 can be used to release the fixation of the patient positioning device 00 on the patient.

[0078] In summary, the embodiments of the present invention provide a radiotherapy device, and the radiotherapy device includes an emergency handling system. Since the emergency handling system can automatically release the fixation of the patient positioning device on the patient, when the patient's physical signs are abnormal during radiotherapy, the patient can be promptly detached from the patient positioning device, that is, the patient can promptly get rid of the restraint of the patient positioning device, effectively avoiding the possible risks brought by the patient positioning device to the patient.

[0079] Optionally, Figure 5 is a schematic structural diagram of another radiotherapy device provided by an embodiment of the present invention. As Figure 5 shown, the radiotherapy device may further include: a patient support device 02. The patient positioning device 00 may include: a first bracket 001, a second bracket 002, a third bracket 003, and a fixing component 004. The first bracket 001 may be respectively connected to the second bracket 002 and the third bracket 003. The second bracket 002 may also be connected to the fixing component 004. The third bracket 003 may also be connected to the patient support device 02.

[0080] Wherein, the emergency treatment system 01 may release the fixation of the patient positioning device 00 to the patient by releasing the connection between the first bracket 001 and the second bracket 002. Or, the emergency treatment system 01 may release the fixation of the patient positioning device 00 to the patient by releasing the connection between the second bracket 002 and the fixing component 004. Or, the emergency treatment system 01 may release the fixation of the patient positioning device 00 to the patient by releasing the connection between the first bracket 001 and the third bracket 003. Or, the emergency treatment system 01 may release the fixation of the patient positioning device 00 to the patient by releasing the connection between the third bracket 003 and the patient support device 02.

[0081] Optionally, the fixing component 004 may be a face mask. The face mask may be a single-layer face mask or a double-layer face mask. The shape of the first bracket 001 may be U-shaped (i.e., the first bracket 001 may be a U-shaped bracket). The second bracket 002 may be a face mask bracket adapted to the first bracket 001. That is, the second bracket 002 and the first bracket 001 may be matched and connected. The third bracket 003 may be an adapter. The third bracket 003 may be used to adaptively connect the patient support device 02 and the first bracket 001 (i.e., the U-shaped bracket).

[0082] Exemplarily, assume that the patient support device 02 is a treatment bed. When the patient positioning device 00 includes an adapter, a U-shaped bracket, a face mask bracket, and a face mask as Figure 5 shown. The adapter may generally be snapped into an electromagnetic induction card slot provided on the front end face (i.e., the side for supporting the patient) of the bed board 1 of the treatment bed. Correspondingly, when receiving an emergency trigger signal, the device release component 20 may control the adapter to disengage from the card slot, so that the patient wearing the patient positioning device 00 can move freely away from the treatment bed.

[0083] Of course, both ends of the U-shaped frame can also be clamped in the card slots provided at both ends of the adapter, and the U-shaped frame and the adapter can be locked by an inductive switch provided in at least one of the card slots. Correspondingly, when receiving an emergency trigger signal, the device release component 20 can unlock the U-shaped frame from the adapter by controlling the inductive switch, so that the patient can move freely away from the treatment bed.

[0084] In an embodiment of the present invention, the problem that the patient positioning device causes great harm to the patient due to restraint when the patient's physical signs are abnormal can also be avoided by adjusting the patient's positioning posture. For example, when positioning the patient, the patient can be made to lie on the side or lie prone on the treatment bed. For the scenario where the patient lies prone on the treatment bed, as Figure 6 shown, a through hole D1 for accommodating the patient's face can be pre-opened on the patient support device 02. In this way, if the patient vomits, the patient will not be suffocated by the vomit blocking the nose and mouth. Optionally, when the patient lies flat on the patient support device, the patient and the patient support device as a whole can be adjusted to an upright state perpendicular to the ground. And, in order to ensure normal treatment in this state, the roller rack in the radiotherapy device can be set or adjusted to a state parallel to the ground.

[0085] It should be noted that after adjusting the patient's posture, correspondingly, the treatment plan for radiotherapy of the patient also needs to be adjusted accordingly.

[0086] In summary, an embodiment of the present invention provides a radiotherapy device, and the radiotherapy device includes an emergency treatment system. Since the emergency treatment system can automatically release the fixation of the patient positioning device on the patient, when the patient's physical signs are abnormal during radiotherapy, the patient can be promptly separated from the patient positioning device, that is, the patient can promptly get rid of the restraint of the patient positioning device, effectively avoiding the possible risks that the patient positioning device may bring to the patient.

[0087] Those skilled in the art will readily think of other embodiments of the present invention after considering the specification and practicing the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of the present invention, which follow the general principles of the present invention and include common general knowledge or conventional technical means in the technical field not disclosed in the present invention. The specification and embodiments are only regarded as exemplary, and the true scope and spirit of the present invention are pointed out by the claims.

[0088] It should be understood that the present invention is not limited to the exact structures described above and shown in the drawings, and various modifications and changes can be made without departing from its scope. The scope of the present invention is only limited by the appended claims.
