Description

Locating and detecting device for locating detector moving in human body

The present invention belongs to the field of medical detection devices, especially a positioning and detection device that can charge and locate a detector moving in the human body by means of wireless transmission.

The existing detectors that can be installed in the body are equipped with an emission source of electromagnetic signals, and transmit the physiological information of the tissues or organs in the body through the electromagnetic signals. Among them, when the electromagnetic signal is transmitted, its signal strength will weaken with the increase of distance, and its attenuation rate is proportional to the value of the square of the distance. Moreover, the distance between the receiving element that receives the signal of the transmitting source and the signal source is very far, so that the signal energy received by the receiving element is very small.

In this embodiment, the positioning and detection device 1 is connected to a server (not shown in the figure), and the server is provided with an arithmetic processor (not shown in the figure) and a display (not shown in the figure) , and the positioning and detection device 1 is further provided with a power module (not shown in the figure) to supply power to the positioning and detection device 1 . The power module is further provided with a sensing element (not shown in the figure) for sensing whether the detector 2 is located within the sensing range of the sensing element. In this embodiment, the sensing element uses By sensing the thermal difference, it can sense that there is the detector 2 in its vicinity, and then activate the power module. Or in other embodiments, the sensing element can further drive the power module by sensing the pressure difference of its adjacent periphery, or sensing metal materials, or sensing the electromagnetic field of the detector 2. the switch.

In addition, in this embodiment, the receiving module 11 and the position correcting modules 13 are arranged in the form of antennas or coils, and have a square structure, a circular structure or a hexagonal structure. Taking a square structure as an example, considering that the center of the square structure is a position where the signal is weak, the receiving module 11 is a state in which a plurality of antennas or coils are stacked. In addition, due to its square structure design, it is more convenient to overlap each other, and it is further convenient to be installed in the positioning and detection device 1 . Or in other embodiments, the receiving module 11 or each of the position correcting modules 13 has a circular structure or a hexagonal structure, so it has different received powers, and the receiving module 11 has a The average side length is about three times the length of the detector 2 , and the detectors are densely stacked on each other, so as to improve the accuracy of the signal received by the receiving module 11 . Or in another embodiment, the receiving module 11 and the position correcting modules 13 are adjacent to each other and are in a parallel state, and any two of the position correcting modules 13 or the receiving module 11 are at a fixed distance from each other. spacing. In yet another embodiment, the receiving module 11 or each of the position correction modules 13 can be partially stacked, that is, not completely overlapped, so that the average signal strength can be improved while at the same time. Improve the coverage area and achieve better communication quality, preferably the center of the receiving module 11 or each of the position correction modules 13 is at the same distance between the same layers, and the distance between the centers of different layers is offset error less than 10%.

Please continue to refer to FIG. 2 , which is a positioning step diagram of a preferred embodiment of the present invention. As shown in the figure, when the user wears the positioning and detection device 1 on his body, and the detector 2 is located in the sensing range of the positioning and detection device 1, the power module will be activated, and The positioning and detection apparatus 1 is activated (step S01). At this time, the detector 2 has not been installed in the human body, and the user has already worn the positioning and detection device 1 on his body. And, the relative position information generated by the position correction modules 13 is transmitted to the positioning module 12 (step S02 ), that is, one of the position correction modules 13 will send out a wireless signal, and at the same time the other positions The calibration module 13 receives the wireless signal to obtain wireless signals with different magnitudes and phase differences, so that the remaining position calibration modules 13 can know the difference between the calibration module 13 and the position calibration module 13 that sent the signal. relative position, and then generate a relative position information. After that, another wireless signal is sent out by another position correction module 13 and received by the other position correction modules 13 , and this operation is repeated until each of the position correction modules 13 completes the transmission of wireless signals . Therefore, the positioning module 12 can construct a three-dimensional coordinate system based on the relative position information.

And in this embodiment, the positioning and detection device 1 will pass the quality control inspection of the product before shipment, wherein the positioning module 12 stores the relative positions of the position correction modules 13 during shipment. News. In addition, the positioning module 12 can use the table lookup method to use the relative position information at the time of shipment as a reference table, and bring it into the three-dimensional coordinate system for calculation, and the calculation method can be linear interpolation or extrapolation. method, or exponential interpolation method or extrapolation method, etc., to obtain the exact relative positions of the position correction modules 13 in actual use. Or in another embodiment, the wireless signal is an electromagnetic signal with a specific waveform, such as a dumbbell-shaped electromagnetic wave, which is then brought into the antenna theory to calculate the position of the position correction module 13 in actual use. In this way, through the three-dimensional coordinate system constructed by the positioning module 12, the relative positions of the position correction modules 13 in actual use can be known, and it can be avoided that these positions are caused by the difference of the user's body shape. The position of the calibration module 13 is offset, thereby causing the positioning module 12 to calculate the deviation of the position of the detector 2 .

Continuing the above description, when the detector 2 is put into the user's body, for example, the detector 2 is swallowed into the human body by the oral cavity, and the detector 2 will move to the gastrointestinal system through the esophagus, and then by the esophagus. Digestive system excreted. Wherein, the receiving module 11 receives the signal sent by the detector 2 and transmits it to the positioning module 12 (step S03 ), and the positioning module 12 is based on some of the signals sent by the detector 2 at this point and The relative position information generated by the position correction modules 13 is used to calculate the current position of the detector 2 (step S04). In addition, the receiving module 11 repeats receiving the signal from the detector 2 at the next time point (step S05 ), that is, repeating the operation of step S03, and the positioning module 12 is still based on the signal sent by the detector 2 at this point. Part of the signals and the relative position information generated by the position correction modules 13 are used to calculate the current position of the detector 2 (step S06), that is, the new position of the detector 2. Next, the positioning module 12 The moving speed of the detector 2 is calculated according to the two different positions calculated before and after and the time difference between the two (step S07 ). At the same time of positioning, the signal transmitted by the detector 2 may also contain the medical information detected by the detector 2 in the body of the user. Therefore, the present invention further includes a detection module 14 and an image conversion module 15 , the detection module 14 is telecommunicationly connected with the receiving module 11 for analyzing part of the signal sent by the detector 2 to obtain the detected human body information. The image conversion module 15 is also connected with the receiving module 11. The telecommunication connection is used to convert part of the signals sent by the detector 2 into images and output them, so that the medical staff can further know other human body information of the user during the positioning process for diagnosis.

In addition, the positioning module 12 can transmit the real-time position and movement rate of the detector 2 to the remote server after calculating the real-time position and movement rate of the detector 2. After the server receives the information, it displays the information, and the information can include the presence of the detector 2 in the human body. The relative position of its organs or tissues at a certain point in the body, its total movement time and its movement speed, the human body information detected by the detector 2, and so on.

In addition, when the positioning module 12 finds that the strength of the signal received by the receiving module 11 is too low, which may cause excessive errors in subsequent calculation results, the positioning module 12 generates a feedback message to the Receive module 11. Wherein, in this embodiment, the above-mentioned signal strength is too small means that after the signal is subjected to wavelet transform to remove background noise, the exponential magnitude of the signal is much smaller than that of the original signal. Then, the receiving module 11 receives the feedback information, and further transmits a command signal for the detector 2 to receive and to increase the signal strength of the detector 2 . Therefore, the strength of the subsequent signal is enhanced to facilitate the continuous sensing operation. Wherein, when the positioning module 12 calculates the signal and the relative position information, it also calculates the feedback information together to correct the signal strength of the signal. In this way, the system can avoid errors when the signal strength is too low, so as to obtain accurate in vivo physiological information.

Furthermore, the operator, such as medical staff or the user himself, can browse the situation detected by the positioning and detection device 1 through the server, and can also use the server to control the positioning and detection device 1 to perform the parameters. Calibration, activation or deactivation of the position calibration modules 13 or algorithm update of the positioning module 12, etc. Moreover, the operator can decide whether to continue the above-mentioned sensing operation (step S08 ). Wherein, if it is decided to end, the power of the positioning and detection device 1 can be interrupted through the server (step S09). On the other hand, if it is determined to continue sensing, the receiving module 11 continues to receive signals. In this way, by knowing the position and moving speed of the detector 2, physiological information in the human body, etc., it can be used to assist medical staff in subsequent diagnosis or treatment operations, thereby improving the efficiency of diagnosis or treatment operations.

In addition, in this embodiment, the receiving modules 11 can be set in plural, and the positioning and detecting device 1 further has a control module 16 , and the control module 16 is connected with the receiving modules 11 by telecommunication , for enabling at least one receiving module 11 and closing the remaining receiving modules 11 . When the detector 2 is in the previous position, it transmits a signal, and at this time the control module 16 will arbitrarily select and activate at least one of the receiving modules 11, and at the same time turn off the rest of the receiving modules 11 , turn on and off the receiving modules 11 in sequence until all the receiving modules 11 have received signals, and continue to provide the signals received by the positioning module 12 . And at the next time point, when the detector 2 moves to the next position, there will be a moving time difference between the detector 2 and the previous position. Likewise, the control module 16 sequentially selects and activates the receiving module 11 and simultaneously turns off the other receiving modules 11, so that the receiving modules 11 can receive the signals at this point and this position. Wherein, the characteristic of the control module 16 is that the switching time of activating and deactivating the receiving modules 11 is shorter than the interval time of the detector 2 continuously transmitting signals. In other words, the switching time required by the control module 16 to switch any two of the receiving modules 11 is smaller than the moving time difference. Therefore, when sensing the position of the detector 2 at each time point, it can be considered that the receiving modules 11 are performing sensing operations at the same time, that is, receiving the signals from the detector 2 at the same time. In this way, the control module 16 can control the opening and closing of the receiving modules 11 , not only can the position and speed of the detector 2 be accurately measured, but also the energy of the receiving modules 11 can be controlled. Therefore, the use frequency and production cost of the receiving modules 11 can be reduced, and the use of the positioning module 12 can be reduced at the same time. Moreover, the energy consumption rate of the receiving modules 11 can be reduced thereby, and the volume of the positioning and detection device 1 can be further reduced.

In addition, the signal transmitted by the detector 2 is an electromagnetic signal, so the receiving module 11 can receive the magnitude and phase of the signal, and the relative positions between the position correction modules 13 have been calculated and obtained, and The position of detector 2 can be further known. Therefore, the operation parameters of the positioning module 12 include the signal strength, signal vector and relative position information of the signal, and the switching time of the control module 16 . Therefore, the position and movement rate of the detector 2 can be quickly calculated and obtained, and the accuracy can be improved.

In addition, the positioning and detection device 1 is a belt structure for looping and wearing on the abdomen, and for sensing the detector 2 that can be placed on the abdomen, and the inner surface of the belt structure is tied There are the receiving module 11 and the position correcting modules 13 . In addition, the positioning and detection device 1 can also have a jacket-like structure, and the receiving module 11 is disposed inside the positioning and detection device 1 to be close to the body for the user to wear. Or in other various embodiments, the positioning and detection device 1 can be installed at the chest cavity, the pelvis or the arm, then the positioning and detection device 1 is in the form of a ring belt structure and is respectively arranged at the chest, the groin and the arm. . Therefore, the appearance structure of the positioning and detection device 1 is different from the installation position of the detector 2 , and is not limited to the above-mentioned embodiment.

The frequency of the position correction modules 13 or the receiving module 11 is 2.4GHz for transmitting and receiving signals, and the frequency of the power transmission module 17 can be 433MHz for transmitting electric energy. Or in another embodiment, the frequency of the receiving module 11 or the position correction modules 13 for receiving signals is 433MHz, and the frequency of the power transmission module 17 for charging is 13.56MHz, or 27MHz, Or the frequency value in any ISM band (Industrial Scientific Medical Band), and the structure setting with more turns.
