Description

Emergency treatment system and radiotherapy equipment

Technical Field

The invention relates to the field of radiotherapy, in particular to an emergency treatment system and radiotherapy equipment.

Background

Radiotherapy is one of the main means for treating tumors by radiation, and the irradiation of radiation can cause cancer cells to die or die. However, if there is a deviation between the radiation irradiation position and the tumor position, not only the cancer cells are not effectively killed, but also other healthy organs are damaged by the radiation being erroneously irradiated. Accurate localization of the tumor location is therefore of great importance when performing radiation therapy.

In the related art, in order to avoid the deviation between the radiation irradiation position and the tumor position caused by the erroneous movement of the patient, a patient positioning device is generally used to fix the posture of the patient to prevent the erroneous movement of the patient. For example, to avoid mis-movement of the patient's head, a head positioning device mask may be used to secure the patient's head.

However, the patient positioning device may pose other risks to the patient because the patient cannot be timely disconnected from the patient positioning device when the patient's physical signs are abnormal. For example, if the patient vomits during radiation therapy, the patient may be suffocated with the vomit because the patient cannot timely detach the head positioning device.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Fig. 1 is a schematic structural diagram of an emergency processing system according to an embodiment of the present invention. As shown in fig. 1, the system may include: a target assembly 10 and a device release assembly 20.

In an embodiment of the present invention, the target assembly 10 may be coupled to the device release assembly 20, and the device release assembly 20 may be configured to couple to a patient positioning device (not shown in FIG. 1). The target assembly 10 may send an emergency trigger signal to the device release assembly 20. The device release assembly 20 may release the patient positioning device from securing the patient in response to the emergency trigger signal.

Alternatively, the target assembly 10 may send the emergency trigger signal directly to the device release assembly 20; alternatively, the target assembly 10 may also forward the received emergency trigger signal to the device release assembly 20. In a scenario where the target assembly 10 directly sends the emergency trigger signal to the device release assembly 20, when the patient has abnormal physical signs (such as vomiting), the target assembly 10 may be triggered to send the emergency trigger signal to the device release assembly 20 through a preset operation. Alternatively, the target assembly 10 may actively detect whether the patient condition is abnormal, and automatically send an emergency trigger signal to the device release assembly 20 when the patient condition is detected to be abnormal.

The patient positioning device can be a structure which is used for fixing the part (such as the head, the head and neck, the body and the like) of a patient to be treated on a patient supporting device (such as a treatment bed) and preventing the patient from moving by mistake in the radiation treatment process. And the patient positioning device may comprise a plurality of movably connected parts, i.e. the patient positioning device may be composed of a plurality of movably connected parts. For example, the patient positioning device may be a positioning device (e.g., a mask) for immobilizing the head or neck of a patient.

Accordingly, when the device release assembly 20 receives the emergency trigger signal, the device release assembly 20 may disengage the patient support device by controlling the patient positioning device as a whole to release the patient positioning device from securing to the patient. Alternatively, the device release assembly 20 may be disconnected at the components that control the articulation of the patient positioning device to release the patient from the patient positioning device. The embodiment of the present invention is not limited thereto.

For example, assuming that the target assembly 10 is a device for detecting patient signs, a patient lies on a patient supporting device, and the patient wants to vomit during the tumor therapy, at this time, the target assembly 10 can detect that the patient signs are abnormal, and the target assembly 10 can actively send an emergency trigger signal to the device release assembly 20 in time. The device release assembly 20, upon receiving the emergency trigger signal, may timely control the patient positioning device to disengage from the patient support device, thereby releasing the patient positioning device from securing to the patient. Furthermore, the patient can sit up in time from the patient support device to vomit, and the risk that the patient cannot be separated from the patient positioning device and is suffocated by vomitus is effectively avoided.

In summary, the embodiment of the present invention provides an emergency processing system. The system includes a target assembly that can send an emergency trigger signal to a device release assembly that can release the patient positioning device from securing the patient in response to the emergency trigger signal, and a device release assembly coupled to the target assembly. Because the device removing component in the emergency treatment system can automatically remove the fixation of the patient positioning device to the patient in response to the emergency trigger signal from the target component, the patient can timely break away from the patient positioning device when the physical sign of the patient is abnormal in the radiotherapy process, namely, the patient can timely break away from the constraint of the patient positioning device, and the risk of the patient positioning device to the patient is effectively avoided.

Optionally, in embodiments of the present invention, the target assembly 10 may also be configured to be coupled to a patient support device. Accordingly, the target assembly 10 may specifically send an emergency trigger signal to the device release assembly 20 upon detecting that the patient support device is in the predetermined position.

The patient support device can be a structure for supporting a patient during radiation therapy of the patient. For example, the patient support device may be a treatment couch or a treatment chair, and the treatment couch is used as an example for the embodiment of the present invention. The preset position can be a preset position, and the patient at the preset position can not collide with a radiotherapy device (such as a treatment head in the radiotherapy device or the wall of a treatment roller) included in the radiotherapy equipment due to the mistaken movement. This preset position can therefore also be referred to as the safety position.

In the case of a radiotherapy apparatus having a small treatment space, if a patient sits directly on a treatment couch while not moving to a safe position, the patient may collide with a treatment head or a drum wall of a radiotherapy device included in the radiotherapy apparatus. Therefore, the target assembly 10 can release the fixation of the patient positioning device to the patient by the device release assembly 20 when the patient support device is in the preset position by sending the emergency trigger signal to the device release assembly 20 when the patient support device is detected to be in the preset position (i.e., the safe position), thereby further effectively avoiding the injury to the patient. Of course, if the treatment space of the radiotherapy apparatus is large enough, the target assembly 10 does not need to send the emergency trigger signal to the device release assembly 20 when the patient support device is detected to be in the preset position.

In an embodiment of the invention, the target assembly 10 may send a movement control signal to the patient support device instructing the patient support device to move to the preset position prior to sending the emergency trigger signal to trigger the patient support device to move to the preset position first. In addition, the target assembly 10 may receive a safety indication signal sent after the patient support device is moved to the preset position, and determine that the patient support device is in the preset position based on the safety indication signal. Optionally, the movement control signal may also be an emergency trigger signal, that is, the target assembly 10 may first send the emergency trigger signal to the patient support apparatus, and then send the emergency trigger signal to the apparatus release assembly 20 when it is detected that the patient support apparatus moves to the preset position.

That is, the target assembly 10 may not only send control signals to the patient support device to control the movement of the patient support device, but may also receive indicator signals from the patient support device to determine whether the patient support device is in the preset position based on the indicator signals.

It should be noted that a positioning assembly (e.g., a position sensor) may be disposed on the patient support device, and the patient support device may detect its real-time position via the positioning assembly.

Optionally, in an embodiment of the present invention, the target assembly 10 may also be configured to be coupled to a radiation therapy device. Accordingly, the target assembly 10 may also send an emergency trigger signal to the radiation therapy device to trigger the radiation source of the radiation therapy device to stop radiation therapy prior to sending the emergency trigger signal to the device release assembly 20 or simultaneously with sending the emergency trigger signal to the device release assembly 20.

By triggering the radiation source of the radiation therapy device in advance to stop radiation therapy before the emergency trigger signal is sent to the device release assembly 20 or while the emergency trigger signal is sent to the device release assembly 20, that is, before the device release assembly 20 releases the fixation of the patient positioning device to the patient, the risk that the radiation source radiates other normal organs of the patient due to the fact that the patient moves in a large range after the fixation of the patient positioning device to the patient is released can be effectively avoided, that is, the injury to the patient is further avoided.

It should be noted that the target assembly 10 may be configured to be coupled to both a radiation therapy device and a patient support device in order to effectively avoid injury to the patient. Prior to sending the emergency trigger signal to the device release assembly 20, the target assembly 10 may first control the radiation source of the radiation treatment device to stop radiation treatment, then control the patient support device to move to a predetermined position (i.e., first turn off the source and then move the couch), and finally send the emergency trigger signal to the device release assembly 20 to trigger the device release assembly to release the patient positioning device from the patient. Of course, the target assembly 10 can also control the patient support to move to the preset position while the radiation source of the radiation treatment apparatus is controlled to stop radiation treatment. The embodiment of the present invention is not limited thereto.

As an alternative implementation manner, fig. 2 is a schematic structural diagram of another emergency processing system provided in the embodiment of the present invention. As shown in fig. 2, the target component may include: an emergency signal generator 101.

The emergency signal generator 101 may be connected to the device release assembly 20, and the emergency signal generator 101 may transmit an emergency trigger signal to the device release assembly 20. That is, in the above embodiment, it is possible that the emergency trigger signal is directly transmitted from the target assembly 10 to the device release assembly 20, the patient support device movement is directly controlled by the target assembly 10, and the radiation source of the radiation treatment device is directly controlled by the target assembly 10 to stop the radiation treatment. By directly sending signals to each component from the target component 10, control efficiency can be improved while effectively avoiding injury to the patient.

As another alternative implementation manner, fig. 3 is a schematic structural diagram of another emergency processing system provided in the embodiment of the present invention. As shown in fig. 3, the target assembly 10 may include: a controller 102 and an emergency signal generator 101.

The controller 102 may be connected to the emergency signal generator 101 and the device release assembly 20, respectively. The emergency signal generator 101 may send an emergency trigger signal to the controller 102, and the controller 102 may forward the emergency trigger signal to the device release assembly 20. That is, in the above embodiment, it may be that the controller 102 forwards the emergency trigger signal from the emergency signal generator 101 to the device disarming assembly 20 and the radiation source. And may be controlled by the controller 102 for movement of the patient support.

By forwarding the signals from the emergency signal generator 101 to the respective components by the controller 102, the control reliability can be improved on the premise of effectively avoiding injury to the patient.

It should be noted that an alarm (e.g., at least one of a buzzer and a light emitting diode) may be further disposed in the target assembly 10, and accordingly, the target assembly 10 may send an alarm signal through the alarm while sending the emergency trigger signal to the device release assembly, so as to prompt a treating physician to adjust the treatment of the patient in time according to the alarm signal, thereby further ensuring the reliability of the treatment of the patient.

Optionally, the controller 102 may be a central processor. The emergency signal generator 101 may include: a trigger button (also referred to as a panic button) and a vital signs detector. The vital sign detector can be used to detect a vital sign of a patient, e.g., the vital sign detector can be a wearable device (e.g., a bracelet) for detecting a vital sign of a patient.

An alternative implementation: when the emergency signal generator 101 includes a trigger button and a sign detector, the emergency signal generator 101 may send an emergency trigger signal after receiving a trigger instruction for the trigger button; or, on the premise of emergency signalness, the triggering reliability is guaranteed. If, if in the radiotherapy in-process, when the patient takes place syncope, fail in time to trigger this trigger button, at this moment, the sign surveys the wearing device and can initiatively detect out patient's vital sign to emergent trigger signal is sent automatically, has further ensured the reliability of sending emergent trigger signal. The generator 101 may send an emergency trigger signal upon detecting an abnormality in the vital signs of the patient. Also, where the emergency signal generator 101 includes a trigger button, the emergency signal generator 101 may be held by the patient in order to facilitate the patient to trigger the trigger button.

By setting two trigger modes, the flexibility of triggering can be improved

It should be noted that, if the emergency signal generator 101 first receives the trigger instruction for the trigger button, the emergency signal generator 101 may execute the operation of sending the emergency trigger signal according to the trigger instruction, and does not need to send the emergency trigger signal again when it is subsequently detected that the vital sign of the patient is abnormal. Similarly, if the emergency signal generator 101 automatically detects that the vital sign of the patient is abnormal first, the emergency signal generator 101 may execute the operation of sending the emergency trigger signal according to the detection result, and does not need to send the emergency trigger signal again when receiving the trigger instruction for the trigger button in the following.

Because the triggering instruction and the detected vital sign aiming at the triggering button do not have the sequence, the control method can avoid sending the emergency triggering signal for many times, waste the processing resource of the emergency signal generator and ensure that the device releasing component 20 can reliably release the fixation of the patient positioning device to the patient according to the emergency triggering signal.

Another optional implementation manner: when the emergency signal generator 101 comprises a sign detector, the emergency signal generator 101 may send an emergency trigger signal when detecting an abnormality in a vital sign of a patient. I.e. the emergency signal generator may simply be a sign detector for detecting a vital sign of the patient.

Optionally, in an embodiment of the present invention, the patient positioning device may include: at least two movably connected parts. The device release assembly 20 may include: a mechanical-electrical interface disposed at the articulating component of the patient positioning device.

For example, the patient positioning device may include a patient positioning device body and a clip member, and the clip member and the patient positioning device body may be movably connected through a mechanical-electrical interface, i.e., the mechanical-electrical interface may be disposed at the movable connection of the clip member and the patient positioning device body. In use, the mechanical electrical interface may release the patient from the patient positioning device by disconnecting the clip member from the patient positioning device body.

Alternatively, the patient positioning device body may be composed of at least two parts, and each part may be movably connected through a mechanical-electrical interface, i.e. the mechanical-electrical interface may be provided at the movable connection of at least two parts of the patient positioning device body. In use, the mechanical-electrical interface may release the patient positioning device from the patient by disconnecting at least two components of the patient positioning device body.

It should be noted that the patient positioning device body can be connected to the patient support device by the clip, for example, the patient support device includes an electric induction slot, and the patient positioning device body can be connected to the electric induction slot by the clip. Optionally, the clip member and the electrical sensing card slot may be movably connected through a mechanical-electrical interface. When the patient positioning device is used, the mechanical-electrical interface can disconnect the patient positioning device integrally from the patient supporting device by disconnecting the connection between the clamping piece and the electric induction clamping groove, so that the fixation of the patient positioning device to the patient is released.

It should be noted that, in the embodiment of the present invention, the target assembly 10, the device release assembly 20, the patient support device, and the treatment head (including the radiation source) of the radiation treatment device may be configured with driving devices, and accordingly, for the above embodiments, the driving devices respectively corresponding to the target assembly, the device release assembly, and the patient support device may receive or transmit signals, and control the movement thereof according to the received signals. Alternatively, the drive device may comprise a logic circuit and a corresponding mechanical drive structure.

In summary, the embodiment of the present invention provides an emergency processing system. The system includes a target assembly that can send an emergency trigger signal to a device release assembly that can release the patient positioning device from securing the patient in response to the emergency trigger signal, and a device release assembly coupled to the target assembly. Because the device removing component in the emergency treatment system can automatically remove the fixation of the patient positioning device to the patient in response to the emergency trigger signal from the target component, the patient can timely break away from the patient positioning device when the physical sign of the patient is abnormal in the radiotherapy process, namely, the patient can timely break away from the constraint of the patient positioning device, and the risk of the patient positioning device to the patient is effectively avoided.

Fig. 4 is a schematic structural diagram of a radiotherapy apparatus provided by an embodiment of the invention. As shown in fig. 4, the radiotherapy apparatus may comprise a patient positioning device 00, and an emergency treatment system 01 as shown in any of fig. 1 to 3. The emergency treatment system 01 may be coupled to the patient positioning device 00 and the emergency treatment system 01 may be used to release the patient positioning device 00 from the patient.

In summary, embodiments of the present invention provide a radiotherapy apparatus comprising an emergency treatment system. Because this emergency treatment system can relieve patient positioner automatically and to patient's fixed, consequently can make the patient in the radiation therapy in-process sign appear when unusual, in time break away from patient positioner, even make the patient can in time break away from patient positioner's constraint, effectively avoided patient positioner to the risk that the patient probably brought.

Optionally, fig. 5 is a schematic structural diagram of another radiation therapy apparatus provided in the embodiment of the present invention. As shown in fig. 5, the radiotherapy apparatus may further comprise: the patient support device 02. The patient positioning device 00 may comprise: a first stent 001, a second stent 002, a third stent 003, and a fixation assembly 004. This first support 001 can be connected with second support 002 and third support 003 respectively, and this second support 002 can also be connected with fixed subassembly 004, and this third support 003 can also be connected with patient support device 02.

Wherein the emergency treatment system 01 may release the patient positioning device 00 from the patient by releasing the connection between the first bracket 001 and the second bracket 002. Alternatively, the emergency treatment system 01 may release the patient positioning device 00 from the patient by releasing the connection between the second bracket 002 and the securing assembly 004. Alternatively, the emergency treatment system 01 may release the patient positioning device 00 from the patient by releasing the connection between the first bracket 001 and the third bracket 003. Alternatively, the emergency treatment system 01 may release the patient positioning device 00 from the patient by releasing the connection between the third bracket 003 and the patient support device 02.

Optionally, the fixing assembly 004 may be a facial mask, which may be a single-layer facial mask or a double-layer facial mask; the first support 001 may be U-shaped (i.e., the first support 001 may be a U-shaped frame), and the second support 002 may be a mask support adapted to the first support 001. That is, the second bracket 002 and the first bracket 001 can be connected in a matching manner. The third bracket 003 can be an adapter, and the third bracket 003 can be used to matingly connect the patient support apparatus 02 and the first bracket 001 (i.e., a U-shaped frame).

By way of example, the patient support device 02 is assumed to be a treatment couch. When patient positioning device 00 includes an adapter, a U-shaped frame, a mask support, and a mask as shown in fig. 5. The adapter can be clamped in an electric induction clamping groove arranged on the front end face (namely the face used for supporting a patient) of a bed plate 1 of the treatment bed, and correspondingly, the device releasing component 20 can be separated from the clamping groove by controlling the adapter when receiving an emergency trigger signal, so that a patient wearing the patient positioning device 00 can be separated from the treatment bed to move freely.

Of course, the two ends of the U-shaped frame can also be clamped in the clamping grooves arranged at the two ends of the adapter, and the U-shaped frame and the adapter are locked by the electric induction switch arranged at least one end of the clamping groove, and correspondingly, the device release assembly 20 can unlock the U-shaped frame and the adapter by controlling the electric induction switch when receiving the emergency trigger signal, so that the patient can move freely without separating from the treatment bed.

In the embodiment of the invention, the positioning pose of the patient can be adjusted, so that the problem that the patient is greatly injured due to the restraint of the patient positioning device on the patient when the physical signs of the patient are abnormal is solved. For example, the patient can lie on his side or on his/her stomach on the treatment couch while sitting. To the scene that the patient bends over on the treatment couch, as shown in fig. 6, a through hole D1 for accommodating the face of the patient can be provided in advance on the patient supporting device 02. Thus, if the patient vomits, the patient will not be suffocated by blocking the nasal opening with the vomit. Alternatively, the patient and the patient support apparatus as a whole can be adjusted to an upright position perpendicular to the floor when the patient lies flat on the patient support apparatus. Also, in order to ensure normal treatment in this state, the drum frame in the radiotherapy apparatus may be set or adjusted in a state parallel to the ground.

It should be noted that, after the pose of the patient is adjusted, the treatment plan for the radiotherapy of the patient needs to be adjusted accordingly.

In summary, embodiments of the present invention provide a radiotherapy apparatus comprising an emergency treatment system. Because this emergency treatment system can relieve patient positioner automatically and to patient's fixed, consequently can make the patient in the radiation therapy in-process sign appear when unusual, in time break away from patient positioner, even make the patient can in time break away from patient positioner's constraint, effectively avoided patient positioner to the risk that the patient probably brought.
