The device for detecting the patency of the cavity or the channel provided by the specific embodiment comprises: an internal swallowing part 1 entering a cavity or a channel and an external detection device 2; the internal swallowing part 1 comprises an inner core part 11 provided with a signal emitting part and a deformation part wrapped on the periphery of the inner core part 11, and the deformation part can be deformed, disintegrated, reduced in volume or degraded after entering a cavity or a channel for a certain time; the external detection device 2 is provided with a signal receiving section for receiving the signal transmitted by the signal transmitting section.
It should be noted that the signal sent by the signal sending part may be a magnetic field signal, an ultrasonic signal, or a corresponding signal sent to the outside in the form of an RFID, which is determined specifically according to the actual situation and is not described herein.
In the using process, firstly, the internal swallowing part 1 enters a channel or a cavity, which can be a swallowing mode or other modes, after the internal swallowing part 1 enters the channel or the cavity for a certain time, whether the internal swallowing part 1 exists in a user body needs to be detected, at this time, the internal swallowing part 1 needs to be detected by using external setting, in the detecting process, only whether the signal receiving part can successfully receive a signal sent by the signal transmitting part needs to be observed and judged, when the signal receiving part can successfully receive the signal sent by the signal transmitting part, the fact that the internal swallowing part 1 still exists in the cavity or the channel of the user is proved, and the smoothness of the detected cavity or channel is poor; when the signal receiving part can not receive the signal sent by the signal transmitting part, the fact that the internal swallowing part 1 is discharged out of the body by a user is proved, and the smoothness of the detected cavity or channel is good; after a certain time, if the inner swallow part 1 is detected not to be discharged, the deformation part is deformed and disintegrated into a plurality of units with smaller volume, so that the disintegrated part and the inner core part 11 are conveniently discharged out of a cavity or a channel; the volume can be reduced to a size convenient for discharging; or the deformation part can be degraded, only the inner core part 11 is left, and the volume of the inner core part 11 is small, so that the deformation part is convenient to discharge.
In the using process, the internal swallow part 1 with different sizes can be designed according to the different sizes of the cavity or the channel to be detected, and the size is determined according to the actual situation.
Compared with the prior art, the device for detecting the patency of the cavity or the channel provided by the embodiment judges whether the internal swallowing part 1 is discharged from the body or not by judging whether the external detection equipment 2 receives the signal sent by the signal transmitting part or not, the detection process is convenient and easy to operate, and the device can be applied to different cavity or channel environments; in addition, aiming at the use mode of swallowing, the internal swallowing part 1 can not be repeatedly used in the use process, and the risk of cross infection can be effectively reduced.
In addition, when the external detection device 2 can still successfully receive the signal sent by the signal emitting part after a certain time, that is, under the condition that the internal swallow part 1 cannot be smoothly discharged, at this time, the deformation part will deform and disintegrate to be decomposed into a structure with a small volume which is easy to discharge, or the volume is reduced through a form of air release, or the deformation part is degraded to expose the core part 11 in the internal swallow part 1 or only leave the core part 11, and the substance after the deformation part is degraded can be small molecules or soluble substances dissolved in water, so that the core part 11 can be conveniently discharged, and the condition that the internal swallow part 1 is retained in a cavity or a channel is avoided. In conclusion, the device for detecting the patency of the cavity or the channel provided by the invention not only is convenient in detection process, but also can avoid the patency of the cavity or the channel.
On the basis of the above-described embodiment, the signal transmitting section may be a magnet for providing a magnetic field, the signal receiving section may be configured to receive a magnetic field signal provided from the magnet, and the external detection apparatus 2 may be further provided with a position calculating section configured to calculate a position of the internal swallow section 1 based on a change in the magnetic field signal at different positions.
The magnet can be a permanent magnet or an electromagnet, when the permanent magnet is used, the permanent magnet can provide a magnetic field signal, and the arrangement of parts such as a power supply and the like is omitted, so that the number of the parts is reduced, the structure is simple, and the production cost is reduced.
In the using process, after the internal swallow part 1 enters the channel or the cavity, the magnetic field signal can be always existed due to the existence of the permanent magnet, if the signal receiving part can still receive the magnetic field signal near the abdomen of the user after the specified time, the internal swallow part 1 is still existed in the body of the user and is not discharged by the user, and the tested smoothness of the cavity or the channel has a problem.
Because the intensity of the magnetic field changes along with the difference of the distance from the magnetic field center, in the using process, the external detection device 2 can be placed at different positions, the magnetic field intensity at different positions can be detected, and the position of the permanent magnet is calculated according to the change of the magnetic field intensity at different positions, namely the position of the internal swallowing part 1.
The detection of the position of the internal swallowing part 1 can effectively judge the moving condition of the internal swallowing part 1 after entering the detection cavity or channel, and is beneficial to judging the unobstructed degree of the cavity or channel.
On the basis of the above embodiment, the internal swallowing part 1 further includes a power supply for supplying electric energy to the signal transmitting part, and the signal transmitting part can send a signal to the outside when being communicated with the power supply.
The power supply is arranged to enable the signal transmitting part to be arranged in an active structure, for example, an electromagnet, a radio frequency signal transmitter or other structures meeting requirements can be arranged.
In the using process, when the signal transmitting part is an active device, the types of signals which can be transmitted by the signal transmitting part are increased, and the measurement of more parameters of the internal swallowing part 1 is favorably realized.
Preferably, the signal can be a magnetic field signal, or an ultrasonic signal, or a radio frequency signal; the signal receiving part is a receiving device corresponding to the signal.
On the basis of the above-described embodiment, at least one acceleration sensor for detecting the acceleration of the interior-swallowed part 1 may be provided in the interior-swallowed part 1; the external equipment is provided with a first data receiver for receiving data measured by the acceleration sensor and a first processor for processing the data received by the first data receiver.
In the use process, the acceleration sensor can transmit the detected data to the first data receiver, and the first processor judges the shape and the patency degree of the cavity or the channel according to the acceleration information transmitted by the acceleration sensor.
The arrangement of the acceleration sensor can obtain the motion condition of the interior swallow part 1, so that the posture of the interior swallow part 1 at present can be obtained more intuitively.
Preferably, at least two acceleration sensors may be provided, and the acceleration sensors are respectively provided at different positions of the interior-swallowed part 1, so as to obtain parameters when the interior-swallowed part 1 is in a rotated state.
In the detection process, the acceleration conditions of different parts of the internal swallowing part 1 can be obtained, and comprehensive judgment is carried out by combining the body position of the human body, for example, after the internal swallowing part 1 is swallowed by the human body, when the human body is in a standing posture, the internal swallowing part 1 is generally in a vertical state, when the data measured by the acceleration sensor is not zero, and when the internal swallowing part 1 can be proved to be in a motion state, the smoothness in the section of vertical cavity or vertical channel is proved to be good; when the human body is in a lying posture, the internal swallowing part 1 is generally in a transverse state, and when the data measured by the acceleration sensor is not zero and the internal swallowing part 1 can be proved to be in a motion state, the smoothness in the transverse cavity or channel is proved to be good.
The first processor is mainly used for processing the data received by the first data receiver, for example, the motion speed and direction of the internal swallow part 1 can be calculated according to the data measured by the acceleration sensor.
On the basis of the above embodiment, at least one pressure sensor for detecting the pressure applied to the inside swallowing part 1 may be provided in the inside swallowing part 1; the external equipment is provided with a second data receiver used for receiving data measured by the pressure sensor, a second processor used for calculating a pressure cloud picture of the internal swallow part 1 according to the data received by the second data receiver, and a third processor used for judging the blockage position of the cavity or the channel according to the data measured by the acceleration sensor and the pressure sensor.
Preferably, at least three pressure sensors may be provided, wherein two pressure sensors are respectively provided at both ends of the inner swallow portion 1 in the longitudinal direction, and at least one pressure sensor is provided at the outer peripheral side of the inner swallow portion 1.
In the using process, when the number of the pressure sensors is large, the pressure data received by the second data receiver can be converted into a pressure cloud chart through the second processor, so that the pressure distribution on different parts of the internal swallowing part 1 can be observed conveniently; in addition, the third processor can be used for judging the specific blocking position of the cavity or the channel by combining the data measured by the pressure sensor and the acceleration sensor, for example, when a human body is in a standing state, the specific part of the internal swallow part 1 can be judged by the data measured by the pressure sensor, and the approximate position of the internal swallow part 1 can be measured according to the data measured by the acceleration sensor and the signal emitted by the signal emitting part, so that the specific blocking position of the cavity or the channel can be roughly determined.
On the basis of the above embodiment, the deformation portion may include at least two housing units 12, and at least one of the housing units 12 is a deformation unit that deforms under the action of a magnetic field; in a natural state, the shell units 12 are fixedly connected; under the action of the magnetic field, the deformation unit deforms to separate the fixedly connected shell units 12.
It should be noted that the deformation of the deformation unit mentioned herein may be a material that expands as a whole under the action of a magnetic field, or may be a material that contracts as a whole under the action of a magnetic field, or a material that elongates in a single direction or contracts in a single direction under the action of a magnetic field, which is determined specifically according to actual situations and will not be described herein again.
In addition, the number of the housing units 12 is at least two, and from the viewpoint of facilitating discharging the inside of the body, the larger the number of the housing units 12 is, the smaller the volume of each housing unit 12 after disassembly is, the more advantageous the discharging of the outside of the body is, and from the viewpoint of processing cost and assembling process cost, the smaller the number of the housing units 12 is, the more convenient the assembling is, and therefore, the specific number of the housing units 12 needs to be determined according to actual conditions.
