Technical Field

Background

Currently, capsule endoscopes are widely used in the medical field, and a doctor diagnoses the health condition of a patient based on images acquired from a data recorder by taking the capsule endoscope by the patient to enter the capsule endoscope into the digestive organs such as the stomach and intestinal tract of the human body, taking images using a lens integrated in the capsule endoscope, and transmitting the taken images to the data recorder outside the body of the patient.

However, for patients with a narrow intestinal tract, there is a potential for the capsule endoscope to be trapped inside the body, but currently no effective solution is provided for how to determine the expulsion of the capsule endoscope. In the related art, whether or not the capsule endoscope is discharged outside the body is determined by detecting the magnitude of the acceleration value of the capsule endoscope.

The capsule endoscope ejection detection method applied to the data recorder provided by the present invention will be described with reference to fig. 1 to 2.

Fig. 1 is a schematic flow chart of a method for detecting the discharge of a capsule endoscope according to the present invention, and as shown in fig. 1, the method for detecting the discharge of a capsule endoscope includes:

step 101, receiving a discharge detection request sent by a terminal device. The discharge detection request comprises a target identifier and is used for requesting the data recorder to detect the target capsule endoscope corresponding to the target identifier.

The execution subject of the present invention may be a data recorder or a data processing apparatus provided in the data recorder. Wherein the data processing means may be implemented by a combination of software and/or hardware.

Alternatively, the identification may be a number, code, serial number, etc. of the capsule endoscope. It should be noted that, in order to facilitate the discharge detection for each capsule endoscope, each capsule endoscope is in one-to-one correspondence with an identifier, that is, one capsule endoscope corresponds to a unique identifier, and one identifier corresponds to a unique capsule endoscope.

Optionally, the terminal device sends a discharge detection request, where the discharge detection request includes the target identifier. The discharge detection request is used for requesting the data recorder to detect the target capsule endoscope corresponding to the target identification. That is, the terminal device transmits the discharge detection request to the data recorder in order to request the data recorder to perform discharge detection of the target capsule endoscope.

Alternatively, the terminal device is a device for triggering the data recorder to perform discharge detection on the target capsule endoscope, for example, the terminal device may be a mobile phone, a laptop computer, a tablet computer, or the like. It will be appreciated that a healthcare worker or patient may send an expulsion detection request to the data logger via the terminal device to trigger the data logger to perform expulsion detection of the target capsule endoscope.

Step 102, according to the discharge detection request, a search request is sent. Wherein, the search request includes the target identification.

Based on the above step 101, the data recorder receives the discharge detection request for the target capsule endoscope corresponding to the target identifier sent by the terminal device, and then, the data recorder performs capsule endoscope discharge detection on the target capsule endoscope.

Optionally, the data logger determines the search request based on the target identifier in the discharge detection request. Wherein, the search request includes the target identification. The search request is used for searching the target capsule endoscope corresponding to the target identification.

103, receiving a first response signal within a preset time length, and determining that the target capsule endoscope is in the body of the user; the first response signal comprises a target identifier and a first indication, and the first indication is used for indicating that the target capsule endoscope is successfully searched; alternatively, when the first response signal is not received within a preset time period, it is determined that the target capsule endoscope is not inside the user's body.

It should be noted that, if the target capsule endoscope receives the search request, it is determined whether the target identifier in the search request is the same as the identifier of the target capsule endoscope itself, so as to determine the first indication or the second indication;

if the first indication is the same, a first indication is determined, and the first indication is used for indicating that the target capsule endoscope is searched successfully. It is also understood that the capsule endoscope for which the first indication is indicative of sending the first indication is the target capsule endoscope. After the first indication is determined, a first response signal is determined according to the first indication and the target identification in the search request. For example, the first response signal may include the first indication and the target identification.

If not, a second indication is determined, the second indication indicating that the target capsule endoscope was not successfully searched. It will also be understood that the second indication is used to indicate that the capsule endoscope sending the second indication is not the target capsule endoscope. After the second indication is determined, a second response signal is determined according to the second indication and the target identifier in the search request. For example, the second response signal may include the second indication and the target identification.

Optionally, the data logger determines whether the target capsule endoscope is expelled by determining whether the first response signal is received within a preset time period.

It can be understood that the target identifier in the first response signal is the same as the target identifier of the search request sent by the data recorder, which indicates that the first response signal is indeed a response to the search request sent by the data recorder; further, by the first indication it is known that: the identification of the capsule endoscope sending the first response signal is the same as the target identification, namely, the capsule endoscope sending the first response signal is the target capsule endoscope corresponding to the target identification. Thus, upon receiving the first response signal, it is determined that the target capsule endoscope is not expelled.

Alternatively, when the data recorder receives the first response signal within a preset time period, it is determined that the target capsule endoscope is not expelled.

Alternatively, the target capsule endoscope is determined to have been expelled when the data recorder does not receive the first response signal within a preset length of time.

The invention provides a capsule endoscope discharge detection method, which receives a discharge detection request sent by a terminal device; wherein the discharge detection request includes a target identification; sending a search request according to the discharge detection request; wherein, the search request comprises a target identifier; receiving a first response signal within a preset time length, and determining that the target capsule endoscope is in the body of the user; the first response signal comprises a target identification and a first indication; alternatively, when the first response signal is not received within a preset time period, it is determined that the target capsule endoscope is not inside the user's body. Wherein it is determined by the target identification in the first response signal that the first response signal is indeed a response to a search request issued by the data recorder; meanwhile, the capsule endoscope sending the first response signal can be determined to be the target capsule endoscope corresponding to the target mark through the first indication. This therefore greatly improves the accuracy of the capsule endoscope ejection detection.

Alternatively, fig. 2 is a second schematic flow chart of the capsule endoscope ejection detection method provided by the present invention, and as shown in fig. 2, the capsule endoscope ejection detection method includes:

step 201, receiving a state identifier sent by a target capsule endoscope, and sending the target identifier and the state identifier to a terminal device. The state indicator is used for indicating the target capsule endoscope to enter an intermittent sleep state.

In an embodiment of the invention, the intermittent sleep state is used for instructing the target capsule endoscope to power off components except the transceiver and the timing wake-up device and controlling the timing wake-up device to periodically generate an enabling signal; the enable signal is used to cause the transceiver to enter a sleep state or a wake-up state.

Optionally, one data recorder corresponds to the capsule endoscope one to one, that is, the data recorder is only used for interacting with the capsule endoscope corresponding to the data recorder, where the specific operation of interaction includes that the capsule endoscope transmits an image to the data recorder and sends a status identifier, or the data recorder performs control operations such as discharge detection on the capsule endoscope. The specific operation of the interaction is not limited, and can be set according to actual needs.

Next, a description will be given of a possible implementation of receiving a status flag transmitted from a target capsule endoscope in a case where one data recorder corresponds to a unique capsule endoscope.

In one possible implementation mode, when the data recorder receives the state identifier sent by the capsule endoscope, whether the identifier of the capsule endoscope is the same as the target identifier stored in the data recorder is judged; and if the data record is the same as the target capsule endoscope, determining that the capsule endoscope is the target capsule endoscope corresponding to the data record, and sending the target identification and the state identification to the terminal equipment.

Optionally, one data recorder corresponds to a plurality of capsule endoscopes, that is, the data recorder can interact with a plurality of capsule endoscopes. When one data recorder corresponds to a plurality of capsule endoscopes, the data recorder stores the identifiers of the plurality of capsule endoscopes corresponding thereto.

Next, a description will be given of a possible implementation of the state flag transmitted by the target capsule endoscope in a case where one data recorder corresponds to a plurality of capsule endoscopes.

In a possible implementation manner, when the data recorder receives the state identifier sent by the capsule endoscope, whether the identifier same as the identifier of the capsule endoscope exists in a plurality of target identifiers stored in the data recorder needs to be judged; and if so, determining that the capsule endoscope is a target capsule endoscope corresponding to the data recorder, and sending the target identification and the state identification to the terminal equipment.

It should be noted that, after the data recorder receives the status identifier of the target capsule endoscope, the data recorder sends the target identifier and the status identifier to the terminal device, which achieves the effect of timely notifying the user of the terminal device that the target capsule endoscope enters the intermittent sleep state and subsequently performing discharge detection operation on the target capsule endoscope.

Step 202, receiving a discharge detection request sent by the terminal device. The discharge detection request comprises a target identifier and is used for requesting the data recorder to detect the target capsule endoscope corresponding to the target identifier.

In step 203, a search request is sent based on the discharge detection request. Wherein, the search request includes the target identification.

Optionally, for the descriptions and explanations of step 202 to step 203, reference may be made to the descriptions and explanations of step 101 to step 102, and the same technical effects can be achieved, and in order to avoid repetition, the descriptions are omitted here.

Step 204, determining whether the first response signal is received within a preset time period, if yes, performing steps 205-207, and if no, performing steps 208-210.

Optionally, for the description and explanation of step 204, reference may be made to the description and explanation of step 103 above, and the same technical effect can be achieved, and in order to avoid repetition, the description is not repeated here.

Step 205, determine that the target capsule endoscope is within the body of the user.

When the data recorder receives the first response signal within a preset time period, it is determined that the target capsule endoscope is not expelled.

Alternatively, when the data logger determines that the target capsule endoscope is inside the user's body, multiple rounds of detection may be required to update the target capsule endoscope ejection until it is determined that the target capsule endoscope is not inside the user's body. Specifically, one possible implementation manner of the multi-round detection is as follows: when the target capsule endoscope is determined to be in the body of the user, the discharge detection is suspended, the discharge detection is performed on the target capsule endoscope at regular intervals with the target time length as an interval, and the maximum time length of each detection is a preset time length. And when the target capsule endoscope is determined not to be in the body of the user, ending the discharge detection of the target capsule endoscope.

Step 206, a first indicator light is illuminated, the first indicator light for indicating that the target capsule endoscope is within the body of the user.

Optionally, a first indicator light is included in the data recorder. Wherein the target capsule endoscope is indicated to be within the body of the user when the first indicator light is in a lit state.

Based on the above step 205, in the case where the target capsule endoscope is determined to be inside the body of the user, the first indicator lamp is turned on, so that the user can know that the target capsule endoscope is still inside the body and is not discharged when seeing that the first indicator lamp is in the on state.

Step 207, sending first information to the terminal device, wherein the first information is used for indicating that the target capsule endoscope is in the body of the user.

Wherein the first information is for indicating that the target capsule endoscope is within the body of the user.

Based on step 205, in the event that the target capsule endoscope is determined to be within the body of the user, first information is sent to the terminal.

Step 208, determine that the target capsule endoscope is not within the user's body.

Step 209, a second indicator light is illuminated, the second indicator light for indicating that the target capsule endoscope is not within the user's body.

Optionally, a second indicator light is also included in the data recorder. Wherein when the second indicator light is in a lit state, indicating that the target capsule endoscope is not within the body of the user.

Based on the above step 208, in the case where it is determined that the target capsule endoscope is not present in the body of the user, the second indicator light is turned on, so that the user knows that the target capsule endoscope is not present in the body and has been discharged when seeing that the second indicator light is in the on state.

And step 210, sending second information to the terminal equipment, wherein the second information is used for indicating that the target capsule endoscope is not in the body of the user.

Wherein the second information is for indicating that the target capsule endoscope is not within the user's body.

Based on step 208, in the event that it is determined that the target capsule endoscope is not within the user's body, second information is transmitted to the terminal.

According to the capsule endoscope discharge detection method provided by the invention, after the data recorder receives the state identifier of the target capsule endoscope, the target identifier and the state identifier are sent to the terminal equipment, so that the effect that the user of the terminal equipment is timely informed that the target capsule endoscope enters the intermittent dormant state, and the user of the terminal equipment can subsequently perform discharge detection operation on the target capsule endoscope is achieved. In addition, the data recorder can indicate the discharge detection result by lighting the first indicator lamp or the second indicator lamp and correspondingly sending the first information or the second information to the terminal equipment, so that great convenience is provided for a user to know the discharge detection result, and the efficiency is improved. Further, when the data recorder determines that the target capsule endoscope is inside the user's body, in order to update the target capsule endoscope ejection status to know the latest ejection detection result, multiple rounds of detection are performed until it is determined that the target capsule endoscope is not inside the user's body. Therefore, the user or medical staff can better know the discharge condition of the capsule endoscope, and the reliability of the discharge detection of the capsule endoscope is greatly improved.

The capsule endoscope ejection detection method applied to the objective capsule endoscope provided by the present invention will be described below with reference to fig. 3 to 4.

Fig. 3 is a third schematic flow chart of the capsule endoscope ejection detection method according to the present invention, and as shown in fig. 3, the capsule endoscope ejection detection method includes:

step 301, receiving a search request sent by a data recorder, where the search request includes a target identifier.

In the invention, the search request sent by the data recorder comprises the target identification. It will be appreciated that the capsule endoscope to which the target identifier corresponds is the capsule endoscope that the data recorder is to search for.

Optionally, if the distance between the target capsule endoscope and the data recorder is less than or equal to the communication distance threshold, the target capsule endoscope can receive the search request sent by the data recorder; if the distance between the target capsule endoscope and the data recorder is larger than the communication distance threshold value, the target capsule endoscope cannot receive the search request sent by the data recorder.

Step 302, when the target identification is the same as the identification of the target capsule endoscope, a first response signal is sent to the data recorder. The first response signal includes a target identification and a first indication. The first indication is used to indicate that the target capsule endoscope was successfully searched.

After receiving the search request sent by the data recorder, the target capsule endoscope determines how to respond to the search request by determining whether the target identifier in the search request is the same as the own identifier, based on step 301.

Optionally, the first indication is determined when the target capsule endoscope determines that the target identifier in the search request is the same as the identifier of itself. Wherein the first indication is used to indicate that the target capsule endoscope is successfully searched. It is also understood that the capsule endoscope for which the first indication is indicative of sending the first indication is the target capsule endoscope corresponding to the target identifier in the search request. And after the first indication is determined, determining a first response signal according to the first indication and the target identification in the search request, and sending the first response signal to the data recorder. For example, the first response signal may include the first indication and the target identification.

According to the capsule endoscope discharge detection method provided by the invention, after the target capsule endoscope receives the search request, if the target identification in the search request is determined to be the same as the identification of the target capsule endoscope, a first response signal is determined and sent to the data recorder. According to the invention, on one hand, the target capsule endoscope can determine the first response signal according to the target identification in the search request, and the realization is simpler, so that the detection efficiency of the capsule endoscope discharge detection method is greatly improved; on the other hand, the method is simple to operate, an additional detection instrument is not needed, and the user experience is improved while the detection cost is reduced.

Alternatively, fig. 4 is a fourth schematic flow chart of the capsule endoscope ejection detection method provided by the present invention, and as shown in fig. 4, the capsule endoscope ejection detection method includes:

step 401, acquiring the remaining power of the target capsule endoscope.

It should be noted that, in order to ensure that the target capsule endoscope works for a longer time, a preset threshold is set for the target capsule endoscope. When the residual electric quantity of the target capsule endoscope is larger than a preset threshold value, the target capsule endoscope is in a normal state; when the residual capacity of the target capsule endoscope is smaller than or equal to the preset threshold value, the target capsule endoscope enters an intermittent sleep state. Wherein when the target capsule endoscope is in a normal state, all components in the target capsule endoscope work normally. When the target capsule endoscope is in an intermittent dormant state, the target capsule endoscope powers off components except the transceiver and the timing awakening device and controls the timing awakening device to periodically generate an enabling signal; the enabling signal is used for enabling the transceiver to enter a sleep state or a wake-up state.

For example, the components of the target capsule endoscope include a transceiver, a data processor, a timing wake-up device, an image acquisition sensor, an image processor, a fill light, a power supply, a bluetooth module, and the like. When the target capsule endoscope is in the intermittent dormant state, only the transceiver and the timing awakening device in the target capsule endoscope normally work, and other components except the transceiver and the timing awakening device are powered off and stop working.

Step 402, determining whether the remaining power is less than or equal to a preset threshold, if yes, executing steps 403-404.

Based on the above step 401, the remaining power of the target capsule endoscope is acquired, and then, when it is determined that the remaining power is less than or equal to the preset threshold, steps 403 to 404 are performed.

In step 403, the target capsule endoscope sends a status identifier to the data recorder. The state indicator is used for indicating the target capsule endoscope to enter an intermittent sleep state.

Based on the step 402, the remaining power of the target capsule endoscope is determined to be less than or equal to the preset threshold value, and then the status identifier is sent to the data recorder. The state indicator is used for indicating the target capsule endoscope to enter an intermittent sleep state.

It should be noted that the target capsule endoscope typically has a sufficient amount of power before entering the body. When the target capsule endoscope enters a human body, the target capsule endoscope is shot through the integrated lens in the target capsule endoscope along with the movement of the position and the shot image is transmitted to a data recorder outside the body of a user, and enough electricity is consumed in the process. When the residual electric quantity of the target capsule endoscope is smaller than or equal to the preset threshold value, on one hand, the target capsule endoscope acquires enough images, and on the other hand, the standby time of the target capsule endoscope in a human body is prolonged so that the residual electric quantity can interact with the data recorder, and the phenomenon that the target capsule endoscope cannot respond to a search request due to zero electric quantity in the human body is avoided.

In step 404, the components except the transceiver and the timing wake-up device are powered off, and the timing wake-up device is controlled to periodically generate an enable signal. The enable signal is used to cause the transceiver to enter a sleep state or a wake-up state.

Based on the above step 402, it is determined that the remaining power of the target capsule endoscope is less than or equal to the preset threshold, that is, the target capsule endoscope will enter the intermittent sleep state.

When the target capsule endoscope enters the intermittent sleep state, the target capsule endoscope powers off components except the transceiver and the timing wake-up device, and controls the timing wake-up device to periodically generate an enabling signal. Wherein the enable signal is used to cause the transceiver to enter a sleep state or a wake-up state.

During the intermittent sleep state, the target capsule endoscope controls the timing awakening device to periodically generate an enabling signal and controls the working state change of the transceiver to be changed alternately in an awakening-sleep-awakening-sleep rule.

Step 405, receiving a search request sent by the data recorder, where the search request includes a target identifier.

Optionally, for the description and explanation of step 405, reference may be made to the description and explanation of step 301 above, and the same technical effect can be achieved, and in order to avoid repetition, the description is not repeated here.

At step 406, power is supplied to the data processor.

Based on step 405, the target capsule endoscope receives the search request transmitted from the data recorder, and then the target capsule endoscope needs to respond to the search request. It should be noted that the data processor in the target capsule endoscope is primarily responsible for responding to the search request.

In response to the search request, the target capsule endoscope therefore first resumes power to the data processor for the data processor to function properly.

Step 407, the control data processor obtains the identification of the target capsule endoscope. The identification is stored in the local memory of the target capsule endoscope.

Based on step 406, the data processor resumes normal operation. Next, the target capsule endoscope control data processor acquires an identification of the target capsule endoscope. Wherein the identification is stored in a local memory of the target capsule endoscope.

It is emphasized that each capsule endoscope has its own identification, and the identification of each capsule endoscope is different.

Step 408, judging whether the target mark is the same as the mark of the target capsule endoscope, if so, executing step 409, and if not, executing step 410.

Optionally, after receiving the search request sent by the data recorder, the target capsule endoscope determines whether the target identifier in the search request is the same as the identifier of the target endoscope, so as to determine that a response signal is sent to the data recorder. Specifically, when the target capsule endoscope determines that the target identifier in the search request is the same as the identifier of the target capsule endoscope, a first response signal is determined; when the target capsule endoscope determines that the target identification in the search request is different from the identification of the target capsule endoscope, the second response signal is determined.

One possible implementation of the determination of the first response signal by the target capsule endoscope is described below.

In one possible implementation, the first indication is determined when the target capsule endoscope determines that the target identifier in the search request is the same as its own identifier. Wherein the first indication is used to indicate that the target capsule endoscope is successfully searched. It is also understood that the capsule endoscope for which the first indication is indicative of sending the first indication is the target capsule endoscope corresponding to the target identifier in the search request. After the first indication is determined, a first response signal is determined according to the first indication and the target identification in the search request. For example, the first response signal may include the first indication and the target identification.

One possible implementation of the determination of the second response signal by the target capsule endoscope is described below.

In one possible implementation, when the target capsule endoscope determines that the target identifier in the search request is different from the identifier of the target capsule endoscope, a second indication indicating that the target capsule endoscope is not successfully searched is determined. It will also be understood that the second indication is used to indicate that the capsule endoscope sending the second indication is not the target capsule endoscope. After the second indication is determined, a second response signal is determined according to the second indication and the target identifier in the search request. For example, the second response signal may include the second indication and the target identification.

Next, when the target identifier is the same as the identifier of the target capsule endoscope, step 409 is performed; when the target identification is different from the identification of the target capsule endoscope, step 410 is performed.

Step 409, a first response signal is sent to the data recorder.

When the target identifier is the same as the identifier of the target capsule endoscope, the target capsule endoscope sends a first response signal to the data recorder.

Step 410, a second response signal is sent to the data recorder.

When the target identification is different from the identification of the target capsule endoscope, the target capsule endoscope sends a second response signal to the data recorder.

The capsule endoscope discharge detection method provided by the invention controls the target capsule endoscope to be in a normal state or an intermittent dormant state by judging the residual electric quantity of the target capsule endoscope and the size of a preset threshold value. When the residual electric quantity of the target capsule endoscope is smaller than or equal to the preset threshold value, on one hand, the target capsule endoscope acquires enough images, and on the other hand, the standby time of the target capsule endoscope in a human body is prolonged so that the residual electric quantity can interact with the data recorder, and the phenomenon that the target capsule endoscope cannot respond to a search request due to zero electric quantity in the human body is avoided.

In addition to any of the above embodiments, the following describes the whole process of the capsule endoscope ejection detection with reference to fig. 5, and fig. 5 is a fifth flowchart of the capsule endoscope ejection detection method according to the present invention.

Step 501, the target capsule endoscope acquires the residual power of the target capsule endoscope.

Step 502, the target capsule endoscope judges that the residual capacity is less than or equal to a preset threshold, if so, step 503 is executed, and if not, step 501 is executed.

In step 503, the target capsule endoscope powers down components other than the transceiver and the timed wake-up, and controls the timed wake-up to periodically generate an enable signal.

Step 504, the target capsule endoscope sends a status identification to the data recorder.

And 505, the data recorder receives the state identifier sent by the target capsule endoscope and sends the target identifier and the state identifier to the terminal equipment.

In step 506, the terminal device sends a discharge detection request to the data recorder.

In step 507, the data recorder sends a search request based on the discharge detection request.

Step 508, the target capsule endoscope receives the search request sent by the data recorder.

In step 509, the target capsule endoscope supplies power to the data processor.

Step 510, the target capsule endoscope control data processor obtains an identification of the target capsule endoscope. The identification is stored in the local memory of the target capsule endoscope.

In step 511, the target capsule endoscope determines whether the target identifier is the same as the identifier of the target capsule endoscope, if so, step 512 is executed, and if not, step 513 is executed.

Step 512, the target capsule endoscope sends a first response signal to the data recorder.

Step 513, the target capsule endoscope sends a second response signal to the data recorder.

In step 514, the data recorder determines whether the first response signal is received within a preset time period, if so, step 515 to step 517 are performed, and if so, step 518 to step 520 are performed.

Step 515, the data logger determines that the target capsule endoscope is within the user's body.

At step 516, the data recorder illuminates a first indicator light.

Step 517, the data recorder sends the first information to the terminal device.

At step 518, the data logger determines that the target capsule endoscope is not within the user's body.

The data logger illuminates a second indicator light 519.

Step 520, the data recorder sends the second information to the terminal device.
