Description

Head position monitoring device {APPARATUS FOR MONITORING HEAD POSITION}

The present invention relates to a head position monitoring device. More specifically, it relates to a head position monitoring device capable of measuring and judging information related to a patient's head position, guiding a patient to a correct posture, recording and transmitting it, and providing objective diagnostic data for a patient to a doctor.

The vitreous is a sticky and transparent tissue that mostly fills the inside of the eyeball. If there is bleeding or inflammation in the eye, the vitreous becomes cloudy, resulting in visual impairment. If necessary, there is no functional problem even if the vitreous body is removed. It restores vision by removing the cloudy vitreous, and maintains the eyeball by reattaching the retina in place when there is retinal detachment.

Vitrectomy surgery is widely used as it has the advantages of shorter operation time compared to scleral vault surgery, local anesthesia is possible due to less pain, easy to combine cataract surgery, and shorter recovery period after surgery due to the small incision. .

Vitrectomy surgery is a method in which gas or oil is injected into the eyeball to act on the affected area, and since the retina and retinal tear are located at the back of the eye, in order for these filling materials to effectively act on the affected area, the patient should be in a prone position. Depending on the location of the hiatus, a side-lying position or a sitting position is required. The purpose is to maintain the head position so that the filling material is in contact with the patient's affected area.

However, it is difficult for the patient to maintain a position where the filling material can act effectively. Humans basically lead upright lives and take a supine position when sleeping. Maintaining the head position after surgery is often required to maintain an uncomfortable posture, such as a prone position, for several weeks or rarely months, which is very difficult considering the daily life pattern.

In addition, it is difficult for the doctor to know whether the filling material has worked because the patient has been in the correct posture for how long, whether the patient's recovery ability is reduced because the filling material is insignificant due to incorrect posture, or is the patient's condition through another reason? It is difficult to diagnose whether the

Overall configuration of the system

1A, 1B and 1C are diagrams illustrating a head position monitoring device according to an embodiment of the present invention. FIG. 2 is a conceptual diagram illustrating a configuration of a head position monitoring device according to the embodiment of FIG. 1A .

1A to 1C , the head position monitoring device according to an embodiment of the present invention has the same shape as an eye patch worn by a patient after surgery. In this embodiment, the housing part 100 is fixed to the band fixing part 200 part of the eye patch part 300 to measure and analyze the patient's head position, and data is recorded and transmitted in real time.

The housing unit 100 may be located on the side near the eye operated by the patient, and may be deformed to be located on the opposite side if necessary. Since the weight of the device is not heavy, it is possible to transmit measured and recorded data through a terminal of a nearby patient or a nearby network by attaching it to an eye patch. In particular, since it is located at a designated position in the band fixing unit 200 , it is possible to prevent an error such as installing the patient by changing the left and right sides.

Hereinafter, a specific configuration will be described.

Referring to FIG. 2 , the head position monitoring device according to the present embodiment includes a detection unit 400 , a processing unit 500 , a signal unit 600 , a communication unit 700 , and a power supply unit 900 in the housing unit 100 . . In addition, it may further include a recording unit 800, a band fixing unit 200, and an eye patch unit 300 for storing data so that the data can be additionally recorded and transmitted. Limiting the band fixing unit 200 and the band fixing unit 300 to an additional configuration means that the eye patch 300 and the band fixing unit 200 can be replaced with other components according to the patient's condition or other needs. do.

The detection unit 400 includes an acceleration sensor 410 that measures vectors in the X, Y, and Z-axis directions. The accelerometer may measure how many degrees of head position the normal vector of the coronal plane maintains based on the acceleration of the three axes. Data measured by the acceleration sensor 410 is transmitted to the processing unit and analyzed.

In addition, the detection unit 410 may further include an extension sensor 420 for detecting whether the band fixing unit is extended. Although the drawing shows that the extension sensor 420 directly contacts the band of the band fixing unit 200 to measure whether or not the band is stretched or not, sensors of various methods that can measure the presence or absence of the extension of the band fixing unit 200 are used. Can be used. The extension sensor 420 is used as a means for determining whether the patient's device works.

The extension sensor 420 may be used alone to detect whether the patient is wearing it, and may be used together with the acceleration sensor 410 to determine this. When used with the acceleration sensor 410, when the patient's movement is not detected by the acceleration sensor 410, by additionally detecting whether the band fixing unit 200 is extended using the extension sensor 420, the patient It can be recognized whether the device has been created. If it is possible to determine whether the patient is moving by using other means than the aforementioned sensor, it is possible to check whether the patient is mounted in combination with these other means.

The processing unit 500 includes an operation module and a guide module. The processing unit 500 may be implemented as a system in which a normally processed program and a processor core driving the program are embedded. In addition, it is designed to enable version management of programs as a firmware system.

The operation module of the processing unit 500 calculates a normal vector with respect to the direction of gravity by using the vector value measured by the acceleration sensor 410 of the detection unit 400 . It calculates how much the normal vector in the direction of gravity is based on the patient's coronal plane, and measures this along with the time variable to calculate how long the patient stayed within the proper head position. This can be used as important data for diagnosing the patient's treatment situation.

The effective application time of the patient is calculated by the following formula.

and

), it is compared whether the calculated normal vector exists and whether the head position is within the normal range. If it is out of the normal range or in consideration of the time function, if it is out of the normal range for more than a certain time, the direction can be guided so that the patient can be corrected to the correct position.

It can simply guide you to correct your posture in the forward and backward directions, and when correction is necessary, you can send a signal in various ways, such as guiding the direction and correcting it within the normal range and not generating a correction signal when it is no longer needed. can

These calibration signals are sent from the signal unit 600 . The signal of the signal unit 600 may have various forms, and may take various forms such as voice, sound, vibration, or additional visual signal through connection with peripheral devices in various ways according to the condition of the patient such as hearing impairment.

The communication unit 700 may transmit data including the measured normal vector and time information. Such data may be transmitted to the patient's terminal using a short-distance communication means such as Bluetooth, or data may be transmitted to a remote server through a network using a communication means such as Wi-Fi.

The housing unit 100 accommodates the detection unit 400 , the processing unit 500 , the signal unit 600 , and the communication unit 700 . The shape of the housing part 100 may be manufactured in various sizes and shapes depending on the purpose, and an embodiment thereof will be described again later.

Additionally, a separate recording unit 800 may be included. The data related to the head position of the patient measured in real time may be a large amount of data, and it is also possible to store the data inside the device when a terminal or an app cannot be used depending on the patient's situation. This allows the patient to store all data inside the device until the next treatment after wearing it, which can provide the option of using the device even when the communication environment is not suitable.

In some cases, even when remotely transmitting through Wi-Fi communication, it is not always possible to connect to the network, so after storing and accumulating data in the recording unit 800 , the stored data can be transmitted at a time when access to the network is possible.

Modified Example 1

3A and 3B are diagrams illustrating a head position monitoring device according to another embodiment of the present invention. 4 is a conceptual diagram illustrating the configuration of the head position monitoring device according to the embodiment of FIG. 3A .

Referring to FIGS. 3A and 3B , in the monitoring device according to another embodiment of the present invention, the housing 110 may be fixed on the eye patch 300 . In the drawings, it was manufactured in a small size and installed at the lower end of the eye patch 300 . Since the compact housing 110 has a small size, it does not block the view and ventilation.

The size and shape can be deformed in various ways. For example, the configuration of the device may be configured to be located outside the frame of the eyepatch unit, and the eyepatch unit 300 and the housing unit 100 may be integrally configured.

Referring to FIG. 4 , the configuration in the housing 110 according to the present embodiment is substantially the same as the configuration described in the embodiment of FIG. 2 , and repeated descriptions of components having the same function are denoted by the same reference numerals. Duplicate descriptions in the description will be omitted.

However, since the configuration of the extension sensor 420 has to link the band of the band fixing part 200 from the inside, it can be configured to be connected to the extension sensor 420 by introducing the band into the housing part 100 . The type and configuration of the extension sensor 420 is the same as that described in the embodiment of FIG. 2 in that it can be deformed in various forms if it is a method capable of detecting the extension of the band fixing unit 200 as already mentioned above.

When the housing unit 110 is directly attached to the eye patch 300 , it has the same shape as a general eye patch, and thus has an advantage in that the patient is comfortable to use as if wearing a conventional eye patch. In addition, since the power capacity of the power supply unit 900 that can be relatively mounted may be reduced when the size is reduced, in the present embodiment, it is used for patients who can visit frequently, and in the case of FIG. Discriminatory use is also possible.

5A and 5B are diagrams illustrating a head position monitoring device according to another embodiment of the present invention. 6 is a reference view for showing a state of a housing part applied to another embodiment of the present invention. 7A and 7B are views illustrating a housing of the head position monitoring device according to the embodiment of FIG. 5A .

5A and 5B, the head position monitoring device according to the present embodiment is designed so that the device itself is rotatable by changing the configuration of the housing unit 120 . The head position monitoring device measures the normal vector in the direction of gravity based on the patient's coronal plane. If the patient's general posture is unusual or the treatment position of the eyeball is in a specific direction, this can be corrected for each patient. .

Referring to FIGS. 7A and 7B , the housing unit 120 is divided into an inner housing 121 and an outer housing 122 that are in contact with the face, and if the outer housing is rotatable, the reference point of the device can be easily adjusted. For example, when a doctor first puts the device of the present embodiment on a patient, the patient may wear it and then rotate the outer housing to set a reference point. Since there is a subtle difference between patients, it is possible to simply set a reference point during treatment, and it is also possible to apply it to a patient who needs to stay at a special angle if necessary.

It may include a knob 130 for adjustment to facilitate rotation for adjusting the reference point. The shape may be formed in various shapes in the outer housing 122 in addition to the ones presented.

In the inner housing 121, a horizontal depression 123 may be formed on the patient's face side to facilitate fixing over the patient's zygomatic arch.

Referring to FIG. 6 , in a typical human skull, the temple part is depressed, and the protruding skeleton of the cheek part is formed to extend to the side. The region of the zygomatic arch (A) shown in the drawing shows the boundary of the part that is recessed at the upper part from the side of the face, but protrudes toward the lower part. By using these physical characteristics, a design in which the head position monitoring device of the present embodiment can be stably fixed may be added.

Accordingly, the inner housing 121 of the housing 120 is formed with a horizontal depression 123 at the bottom so that it can be fixed over the zygomatic arch of the patient on the surface in contact with the patient's face. The position of the depression and the degree of depression can be applied differently depending on the person, and when the device is initially mounted, it is also possible to adjust the shape or position of the depression 1230 to mount it.

application of application

Since the head position monitoring apparatus of the present invention has a communication unit capable of transmitting the measured data to the outside, various applications using such data are possible.

The communication unit 700 may communicate with an external network to provide information about the patient's head position to a server at a remote distance in real time. In particular, since data can be stored in the recording unit 800 , even if the data is not connected to the network in real time, it is possible to accumulate data and transmit the accumulated data at a time when the network can be accessed.

The data transmitted to the server is applied to the program in the server to automatically check the situation that requires warning or guidance, and the doctor in charge can remotely access the server to monitor the patient's treatment status.

Communication unit 700 may provide data to the patient's terminal using a short-distance communication means, which manages data using an app installed in the terminal, etc., and visualizes or analyzes a situation requiring a warning or action, etc. can be made to occur.
