Abstract
Description
Technical Field
[0001] This application relates to the field of medical devices, and in particular to a head position monitoring device. Background Technology
[0002] Pneumatic retinostomy is a low-cost, minimally invasive, and fast-recovery treatment for rhegmatogenous retinal detachment. Its principle is to use air bubbles injected into the vitreous cavity to press against and close the retinal tear. Because the vitreous cavity is a spherical cavity, the injected air bubbles need to reach the location of the retinal tear to accurately press against it. Therefore, for a period after surgery, the patient needs to maintain a certain head position to ensure that the injected air bubbles accurately press against the retinal tear.
[0003] In existing technologies, to avoid adverse consequences, head position monitoring devices are used to monitor changes in the patient's head position after surgery. If the head position deviates beyond a certain degree, an alarm is issued to promptly notify medical staff, allowing them to adjust the patient's head position in a timely manner and prevent the patient from remaining in a deviated head position for an extended period. However, the inventors of this application have discovered that:
[0004] Existing head position monitoring devices can only indicate when the head position has shifted, but cannot guide patients on how to adjust it. Medical staff still need to monitor and adjust it constantly. Therefore, this head position monitoring device can only be used in hospitals and cannot be used at home after discharge, which increases the patient's hospitalization costs without reducing the use of medical resources. Summary of the Invention

The external processor generates head position adjustment prompts (including X-axis and / or Y-axis head position adjustment prompts) based on the real-time head position information and sends them to the communication module. The first terminal device displays these prompts to the target patient. When head position shifts, medical personnel do not need to adjust the head position.

This solves the problem that existing head position monitoring devices can only be used in hospitals, thus increasing hospitalization costs without reducing the use of medical resources.

[0055] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0056] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0057] In one exemplary embodiment, such as Figure 1 As shown, a head position monitoring device is provided, including a head position information monitoring device 1 and a first terminal device 2. Wherein:
[0058] The head position information monitoring device 1 is used to monitor the real-time head position information of the target patient, including the X-axis rotation angle and the Y-axis rotation angle.
[0059] In this embodiment, the target patient refers to a patient who has undergone pneumatic retinal fixation surgery and requires real-time head position monitoring. The Y-axis is the axis perpendicular to the target patient's face, and the Y-axis rotation angle refers to the angle of rotation around the axis perpendicular to the target patient's face. The X-axis is the pitch axis, and the X-axis rotation angle refers to the angle of rotation around the pitch axis.
[0060] The first terminal device 2 is used to send the real-time head position information of the target patient to the communication module 3, and to display the head position adjustment prompts sent by the communication module 3 to the target patient; wherein, the head position adjustment prompts include X-axis head position adjustment prompts and / or Y-axis head position adjustment prompts.
[0061] In this embodiment, the target patient adjusts their head position to the target position based on the X-axis head position adjustment prompts and / or Y-axis head position adjustment prompts displayed on the first terminal device 2.
[0062] In another exemplary embodiment of this application, the head position monitoring device described above further includes:
[0063] Data storage module 4 is used to store the target head position information and the real-time head position information of the target patient.
[0064] In another exemplary embodiment of this application, the head position information of the target head position also includes the sign bit value of the X-axis rotation angle and / or the sign bit value of the Y-axis rotation angle of the target head position.
[0065] In this embodiment, the values of the X-axis rotation angle and the Y-axis rotation angle can be positive or negative. For example, if the rotation is counterclockwise when viewed along the positive X-axis and Y-axis, the X-axis rotation angle and the Y-axis rotation angle are considered positive; conversely, if the rotation is clockwise when viewed along the positive X-axis and Y-axis, the X-axis rotation angle and the Y-axis rotation angle are considered negative. When the values of the X-axis rotation angle and the Y-axis rotation angle are positive, the sign bit value of the X-axis rotation angle and the sign bit value of the Y-axis rotation angle are 1; otherwise, the sign bit value of the X-axis rotation angle and the sign bit value of the Y-axis rotation angle are 0.
[0066] Accordingly, the aforementioned head position monitoring device also includes a rotation offset calculation device 5 and an offset direction determination device 6, such as... Figure 2 As shown, the rotation offset calculation device 5 includes a first subtractor 5-1 and a second subtractor 5-2, as follows: Figure 3 As shown, the offset direction determination device 6 includes a first comparator 6-1 and a second comparator 6-2, wherein:
[0067] The first input terminal of the first subtractor 5-1 is connected to the first terminal of the head position information monitoring device 1, and the second input terminal of the first subtractor 5-1 is connected to the first output terminal of the data storage module 4. The difference output by the output terminal of the first subtractor 5-1 is the X-axis rotation offset. The first terminal is used to output the real-time X-axis rotation angle of the head position as the first rotation angle, and the first output terminal is used to output the X-axis rotation angle of the target head position as the second rotation angle.
[0068] The first input terminal of the second subtractor 5-2 is connected to the second terminal of the head position information monitoring device 1. The second input terminal of the second subtractor 5-2 is connected to the second output terminal of the data storage module 4. The difference output by the output terminal of the second subtractor 5-2 is the Y-axis rotation offset. The second terminal is used to output the real-time Y-axis rotation angle of the head position as the third rotation angle. The second output terminal is used to output the Y-axis rotation angle of the target head position as the fourth rotation angle.
[0069] The three input terminals of the first comparator 6-1 are connected to the output terminal of the first subtractor 5-1, the first terminal, and the third output terminal of the data storage module 4, respectively. The output of the third terminal is the sign bit value of the second rotation angle. The first comparator 6-1 is configured to: output a first level and send it to the communication module 3 if the sign bit value of the first rotation angle is opposite to the sign bit value of the second rotation angle, or if the sign bit value of the first rotation angle is the same as the sign bit value of the second rotation angle and the X-axis rotation offset is negative; otherwise, output a second level and send it to the communication module 3. The first level indicates that the X-axis offset direction of the real-time head position is opposite to the X-axis head position direction of the target head position, and the second level indicates that the X-axis offset direction of the real-time head position is the same as the X-axis head position direction of the target head position.
[0070] In this embodiment, the X-axis head position of the target head includes downward or upward, and the Y-axis head position includes left or right, specifically determined by the signs of the X-axis and Y-axis rotation angles. For example, if the X-axis rotation angle is negative, the X-axis head position is downward; if the X-axis rotation angle is positive (including the case where the X-axis rotation angle is zero), the X-axis head position is upward. If the Y-axis rotation angle is negative, the Y-axis head position is leftward; if the Y-axis rotation angle is positive (including the case where the Y-axis rotation angle is zero), the Y-axis head position is rightward.
[0071] In this embodiment of the application, the communication module 3 feeds back the received first level or second level to the external processor. The external processor determines the X-axis offset direction of the real-time head position based on the relationship (same or opposite) between the X-axis offset direction of the real-time head position represented by the first level or second level and the X-axis head position direction of the target head position.
[0072] The three input terminals of the second comparator 6-2 are connected to the output terminal of the second subtractor 5-2, the second terminal, and the fourth output terminal of the data storage module 4, respectively. The output of the fourth output terminal is the sign bit value of the fourth rotation angle. The second comparator 6-2 is used to: output a third level and send it to the communication module 3 if the sign bit value of the third rotation angle is opposite to the sign bit value of the fourth rotation angle, or if the sign bit value of the third rotation angle is the same as the sign bit value of the fourth rotation angle and the Y-axis rotation offset is negative; otherwise, output a fourth level and send it to the communication module 3. The third level indicates that the Y-axis offset direction of the real-time head position is opposite to the Y-axis head position direction of the target head position, and the fourth level indicates that the Y-axis offset direction of the real-time head position is the same as the Y-axis head position direction of the target head position.
[0073] In this embodiment, the communication module 3 feeds back the received third or fourth level to the external processor. The external processor determines the Y-axis offset direction of the real-time head position based on the relationship (same or opposite) between the Y-axis offset direction of the real-time head position represented by the third or fourth level and the Y-axis head position direction of the target head position.
[0074] In another exemplary embodiment of this application, such as Figure 4 As shown, the first comparator 6-1 and the second comparator 6-2 have the same structure, both including a first sign bit detection device 7, an XOR gate 8, a NOT gate 9, a second sign bit detection device 10, an AND gate 11, and an OR gate 12. Wherein:
[0075] The input terminal of the first sign bit detection device 7 is connected to the first terminal or the second terminal, and the output terminal of the first sign bit detection device 7 is the sign bit value of the first rotation angle or the sign bit value of the third rotation angle.
[0076] One input of the XOR gate 8 is connected to the output of the first sign bit detection device 7, and the other input is connected to the third or fifth output of the data storage module 4. The output of the XOR gate 8 is connected to the input of the NOT gate 9. The output of the fourth output is the sign bit value of the second rotation angle, and the output of the fifth output is the sign bit value of the fourth rotation angle. The XOR gate 8 is used to detect whether the sign bit value of the first rotation angle is the same as or opposite to the sign bit value of the second rotation angle, or to detect whether the sign bit value of the third rotation angle is the same as or opposite to the sign bit value of the fourth rotation angle.
[0077] In this embodiment, if the input terminal of the first sign bit detection device 7 is connected to the first terminal, then the other input terminal of the XOR gate 8 is connected to the third output terminal of the data storage module 4. The XOR gate 8 is used to detect whether the sign bit value of the first rotation angle is the same as or opposite to the sign bit value of the second rotation angle. If the input terminal of the first sign bit detection device 7 is connected to the second terminal, then the other input terminal of the XOR gate 8 is connected to the fourth output terminal of the data storage module 4. The XOR gate 8 is used to detect whether the sign bit value of the third rotation angle is the same as or opposite to the sign bit value of the fourth rotation angle. The first sign bit detection device 7 adopts an existing sign bit detection device. For example, a processor unit capable of extracting the sign bit (Sign function, which outputs 1 when the input is negative, otherwise outputs 0) is used.
[0078] The input terminal of the second sign bit detection device 10 is connected to the output terminal of the first subtractor 5-1 or the second subtractor 5-2, and the output terminal of the second sign bit detection device 10 is the sign bit value of the X-axis rotation offset or the sign bit value of the Y-axis rotation offset.
[0079] In this embodiment, if the input terminal of the first sign bit detection device 7 is connected to the first terminal, then the input terminal of the second sign bit detection device 10 is connected to the first subtractor 5-1, and the output terminal of the second sign bit detection device 10 is the sign bit value of the X-axis rotation offset. If the input terminal of the first sign bit detection device 7 is connected to the second terminal, then the input terminal of the second sign bit detection device 10 is connected to the second subtractor 5-2, and the output terminal of the second sign bit detection device 10 is the sign bit value of the Y-axis rotation offset. The second sign bit detection device 10 uses an existing sign bit detection device. For example, it uses a processor unit capable of extracting the sign bit (Sign function, which outputs 1 when the input is negative, otherwise outputs 0).
[0080] The two inputs of AND gate 11 are connected to the outputs of the second sign bit detection device 10 and NOT gate 9, respectively. The outputs of AND gate 11 and XOR gate 8 are connected to the two inputs of OR gate 12, respectively. The output of OR gate 12 is used to output a first level, a second level, a third level, or a fourth level and send it to the communication module 3.
[0081] In another exemplary embodiment of this application, the head position monitoring device described above further includes a head position adjustment amount determination device 13, which includes a first absolute value circuit 14, a second absolute value circuit 15, a third comparator 16, and a fourth comparator 17, as follows: Figure 5 As shown. Wherein:
[0082] The input terminal of the first absolute value circuit 14 is connected to the output terminal of the first subtractor 5-1. The output terminal of the first absolute value circuit 14 is connected to the first input terminal of the third comparator 16 and the communication module 3. The second input terminal of the third comparator 16 is connected to the first threshold voltage. The third comparator 16 is used to: output the fifth level and send it to the communication module 3 if the X-axis head position adjustment amount is greater than the preset first threshold voltage; otherwise, output the sixth level and send it to the communication module 3. The first absolute value circuit 14 is used to: perform absolute value calculation on the X-axis rotation offset amount. The output terminal of the first absolute value circuit 14 is the X-axis head position adjustment amount.
[0083] In this embodiment, the communication module 3 feeds back the received fifth or sixth voltage level to the external processor. If the external processor receives the fifth voltage level, it generates an X-axis head position adjustment prompt based on the real-time X-axis offset direction and X-axis head position adjustment amount, and sends it to the communication module 3. The communication module 3 then sends the X-axis head position adjustment prompt to the first terminal device 2 for display. If the external processor receives the sixth voltage level, it does not need to generate an X-axis head position adjustment prompt. The magnitude of the first threshold voltage can be set according to actual needs and is not specifically limited here.
[0084] The input terminal of the second absolute value circuit 15 is connected to the output terminal of the second subtractor 5-2. The output terminal of the second absolute value circuit 15 is connected to the first input terminal of the fourth comparator 17 and the communication module 3. The second input terminal of the fourth comparator 17 is connected to the second threshold voltage. The fourth comparator 17 is used to: output the seventh level and send it to the communication module 3 if the Y-axis head position adjustment amount is greater than the preset second threshold voltage; otherwise, output the eighth level and send it to the communication module 3. The second absolute value circuit 15 is used to: perform absolute value calculation on the Y-axis rotation offset amount. The output terminal of the second absolute value circuit 15 is the Y-axis head position adjustment amount.
[0085] In this embodiment, the communication module 3 feeds back the received seventh or eighth voltage level to the external processor. If the external processor receives the seventh voltage level, it generates a Y-axis head position adjustment prompt based on the real-time Y-axis offset direction and Y-axis head position adjustment amount, and sends it to the communication module 3. The communication module 3 then sends the Y-axis head position adjustment prompt to the first terminal device 2 for display. If the external processor receives the eighth voltage level, it does not need to generate a Y-axis head position adjustment prompt. The magnitude of the second threshold voltage can be set according to actual needs and is not specifically limited here.
[0086] In another exemplary embodiment of this application, the first absolute value circuit 14 and the second absolute value circuit 15 have the same structure, both including an inverter 18, a non-inverting amplifier 19, and a multiplier 20, as shown below. Figure 6 As shown. Wherein:
[0087] The input terminal of inverter 18 is connected to the output terminal of the first subtractor 5-1 or the output terminal of the second subtractor 5-2. The output terminal of inverter 18 is connected to the inverting input terminal of non-inverting amplifier 19. The non-inverting input terminal of non-inverting amplifier 19 is grounded. The output terminals of non-inverting amplifier 19 and inverter 18 are connected to the input terminal of multiplier 20. The non-inverting amplifier 19 is used to amplify the output of inverter 18 in the same phase. The output of multiplier 20 is the X-axis head position adjustment amount or the Y-axis head position adjustment amount.
[0088] In this embodiment, if the input of inverter 18 is negative, the output of non-inverting amplifier 19 is -1, and the output after multiplication by multiplier 20 is the absolute value of the input of inverter 18. If the input of inverter 18 is positive, the output of non-inverting amplifier 19 is 1, and the output after multiplication by multiplier 20 is the input of inverter 18.
[0089] In another exemplary embodiment of this application, the head position information also includes the Z-axis rotation angle.
[0090] In this embodiment, the Z-axis is the gravity axis, and the Z-axis rotation angle refers to the angle of rotation around the gravity axis.
[0091] The first terminal device 2 is also used for:
[0092] The real-time 3D model sent by the communication module 3 is displayed to the target patient. The real-time 3D model is a 3D model of the eyeball that reflects the real-time positional relationship between the retinal tear and the target bubble inside the eyeball of the target patient.
[0093] In this embodiment of the application, the external processor is also used for:
[0094] Based on the head position information of the target head, an overlapping retinal tear model and a target bubble model are constructed at the top position inside the eyeball in the constructed three-dimensional eyeball model to obtain the target three-dimensional model.
[0095] Based on the mapping relationship between the head position information of the target head and the three-dimensional coordinates of the target bubble model in the target three-dimensional model, the real-time three-dimensional coordinates of the target bubble are determined by the real-time head position information of the target patient.
[0096] Based on the real-time 3D coordinates of the target bubble, the position of the target bubble model is updated in the target 3D model to obtain the real-time 3D model and send it to the communication module 3.
[0097] In this embodiment, when the target patient is in the target head position, the target bubble accurately presses against the retinal tear, thus the constructed retinal tear model and the target bubble model overlap. Constructing the overlapping retinal tear model and target bubble model at the top of the eyeball's interior is to more intuitively demonstrate the positional relationship between the retinal tear and the target bubble in the three-dimensional model of the eyeball.
[0098] The real-time 3D model can display the positional relationship between the target bubble and the retinal tear in the eyeball of the target patient under real-time head position, so that the target patient can adjust the head position in time, and the head position adjustment ends when the target bubble model and the retinal tear model overlap in the real-time 3D model.
[0099] When the target patient does not adjust their head position to the target position in real time, there is a misalignment between the target bubble model and the retinal tear model in the real-time 3D model. As the target patient adjusts their head position according to the head position adjustment prompts, the distance between the target bubble model and the retinal tear model in the real-time 3D model gradually decreases. When the target bubble model and the retinal tear model overlap in the real-time 3D model, it means that the head position has been adjusted to the target position, and the target patient can stop adjusting their head position at this time.
