Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by the skilled in the art without creative work belong to the protection scope of the present invention.
An embodiment of the utility model provides a charging device, as shown in fig. 1, charging device include probe detection module 10 and wireless charging module 20. Namely, the charging device is a wireless charging device, and the target probe is charged in a wireless charging mode, so that a charging metal contact for wired charging can be omitted, the phenomena of corrosion, rusting and abrasion of the metal contact can be avoided, and related safety risks can also disappear. In the aspect of structural design, the probe charging seat does not need to be made into a special shape (such as a concave structure), a wireless charging mode is adopted, and the probe charging seat can be designed into other required forms such as a plane and the like from the aspects of attractive design and medical cleaning. In addition, in the aspect of general charging, as long as the probes conforming to the same charging protocol can be charged on the device, the problem that the probe charging seat needs to be matched with the probe can be solved, and the reutilization rate of the probe charging seat is effectively improved.
As shown in fig. 1, the probe detection module 10 includes a probe detection unit 11 and a control unit 12. The probe detection unit 11 is connected with the control unit 12, and the probe detection unit 11 is used for detecting whether the target probe is in place. The in-place refers to whether the target probe is located on the charging device or further located at the correct charging position of the charging device.
The probe detection unit 11 may be implemented by using various detection sensors, for example, a sensor based on the hall principle; other types of detecting units can be used, for example, adaptive signal transmitting and receiving units can be respectively arranged on the target probe and the probe detecting module, whether the target probe is in place can be determined by detecting the strength of the signal, and the like. Of course, other methods may also be used to detect whether the target probe is in place, and the specific type is not limited, and it is only necessary to ensure that the target probe can be detected whether the target probe is in place.
The wireless charging module 20 is connected to the control unit 12, and the control unit 12 is configured to control the operation of the wireless charging module 20 based on the detection result of the probe detection unit 11. Specifically, the probe detection module 10 transmits the detection result to the control unit 12, and the control unit 12 controls the operation of the wireless charging module 20 based on the detection result. For example, when the probe detection module 10 does not detect the target probe, the probe detection module 10 sends a first detection signal corresponding to the target probe not being located to the control unit 12, and the control unit 12 controls the wireless charging module 20 not to operate after receiving the first detection signal; when the probe detection module 10 detects a target probe, the probe detection module 10 sends a second detection signal corresponding to the target probe being in place to the control unit 12, and after receiving the second detection signal, the control unit 12 controls the wireless charging module 20 to operate to start charging the target probe. The control unit 12 may be a selection switch, for example, when the probe detection module 10 sends the first detection signal to the control unit 12, the selection switch disconnects the operating circuit of the wireless charging module 20 (for example, the power supply of the wireless charging module 20 may be disconnected); when the probe detection module 10 transmits the second detection signal to the control unit 12, the selection switch turns on the operating circuit of the wireless charging module 20. Of course, the control unit 12 may be other hardware control circuits, and the specific structure of the control unit 12 is not limited at all.
In the charging device provided in this embodiment, the probe detection module 10 detects whether the target probe is in place, and the control unit 12 controls the wireless charging module 20 to operate based on the detection result; that is, when the target probe is not in place, the control unit 12 controls the wireless charging module 20 not to operate, so as to ensure that the wireless charging module 20 charges the target probe when the target probe is in place, thereby improving the charging efficiency.
As an optional implementation manner of this embodiment, the probe detection unit 11 may be a probe in-place detection sensor, and after the probe in-place detection sensor identifies the target probe, the probe in-place sensor actively outputs a second detection signal and sends the second detection signal to the control unit 12 to notify the control unit 12 that the current target probe is already in place, and after the control unit 12 receives the second detection signal, the wireless charging module is automatically turned on to charge the target probe. The probe in-place detection sensor is a sensor prepared based on a Hall effect, when a target probe is in place, the target probe can affect the magnetic field of the probe in-place detection sensor, and when the magnetic field of the probe in-place detection sensor changes, the magnetic field changes are converted into changes of electric signals, so that the in-place of the target probe can be detected.
In some optional embodiments of this embodiment, as shown in fig. 2, the probe detection unit further includes an alarm sensing sensor connected to the control unit 12. The detection principle of the alarm induction sensor can be similar to that of the probe on-site detection sensor or the probe area detection sensor, and other detection principles can be adopted for detection. For example, the charging device may be divided into an area a, an area B and an area C, wherein the area B is a charging area, and then the probe area detection sensor may be disposed at a position corresponding to the area B, and the alarm sensing sensor may be disposed at a position corresponding to the area a and the area C. It can also be understood that the probe area detection sensor and the alarm sensing sensor are the same sensor, except that the arrangement position of the probe area detection sensor in the charging device is different, and the detection signal sent after the probe area detection sensor detects the target is different.
In other alternative embodiments of this embodiment, as shown in fig. 3, the probe detection unit 11 may further include a probe area detection sensor. The probe in-situ detection sensor and the probe area detection sensor are both connected to the control unit 12, and the probe area detection sensor is used for detecting whether the target probe is at the correct position of the charging device (i.e. whether the target probe is aligned with the charging device). Similar to the detection principle of the probe in-place detection sensor, the probe area detection sensor also detects based on the hall effect. Specifically, the operation principle of the probe detection unit 11 is as follows: when the probe presence detection sensor identifies the target probe, the probe presence detection sensor sends a second detection signal to the control unit 12 to notify the control unit 12 that the target probe is already in place at this time, but this time, it cannot be said whether the target probe is placed at the correct position of the charging device. Therefore, the control unit 12 will automatically determine whether the probe region detection sensor outputs a third detection signal for detecting whether the target probe is at the correct position of the charging device after receiving the second detection signal. When the detecting unit 12 determines that the probe region detecting sensor outputs the third detecting signal, the wireless charging module 20 is turned on to charge the target probe. That is, only when the control unit 12 receives the third detection signal output by the probe region detection sensor, the control unit 12 turns on the wireless charging module 20 to charge the target probe.
This charging device adopts probe region detection sensor to detect whether target probe is in charging device's preset region to just begin to charge when guaranteeing wireless charging module when target probe is in charging device's correct position (promptly, target probe aims at wireless charging module), further improved wireless charging efficiency.
As shown in fig. 2 and 3, the control unit 12 is further connected to an alarm control unit 30, and the alarm control unit 30 may be disposed in the charging device or the target probe, and the installation position of the alarm control unit 30 is not limited herein. In the following description, a detailed description is given taking an example in which the alarm control unit is provided in the charging device.
The operating principle of the alarm control unit 30 is explained here as follows: when the probe in-place detection sensor does not detect the target probe and the alarm sensing sensor detects the target probe, or when the probe in-place detection sensor detects the target probe and the probe area sensor does not detect the target probe, the alarm sensing sensor sends a fourth detection signal to the control unit 12, which indicates that the target probe is not placed at the correct position of the charging device at the moment, and the control unit 12 triggers the alarm control unit to work, so as to remind a user that the position of the target probe needs to be adjusted at the moment.
As an alternative embodiment of this embodiment, as shown in fig. 2 and 3, the alarm control unit 30 includes an alarm signal driving circuit 31, an alarm signal generating circuit 32, and an alarm device 33. The alarm signal driving circuit 31 is connected to the control unit 12, the alarm signal generating circuit 32 is connected to the alarm signal driving circuit 31, and the alarm device 33 is connected to the alarm signal driving circuit 31. When the control unit 12 triggers the alarm control unit to operate, the alarm signal driving circuit 31 triggers the alarm signal generating circuit 32 to generate an alarm driving signal and sends the alarm signal to the alarm signal driving circuit 31, and the alarm signal driving circuit 31 drives the alarm device 33 to send out the alarm signal based on the alarm driving signal.
Wherein, the alarm device 33 may include at least one of an alarm buzzer and an alarm indicator light. When the alarm device is an alarm buzzer or an alarm indicator, the alarm signal generating circuit 32 needs to generate 2 driving signals to drive the alarm buzzer and the alarm indicator, respectively.
As an optional implementation manner of this embodiment, the alarm signal generating circuit 32 may be a signal generator, which may generate a pulse signal, a periodic signal with a preset duty ratio, and the like, wherein what kind of generated waveforms may be set according to actual requirements, and is not limited herein.
The alarm signal driving circuit 31 is a driving circuit adapted to the alarm device 33, and when the alarm device 33 is an LED indicator, the alarm signal driving circuit 31 may be a driving circuit adapted to the LED indicator; when the alarm device is a 33 alarm buzzer, then the alarm signal driving circuit 31 may be a power amplifier or the like. The structure of the alarm signal driving circuit 31 may be designed according to actual requirements, and is not limited herein.
In some optional implementations of the present embodiment, the wireless charging module 20 includes a wireless charging control transmitting circuit 21, a wireless charging transmitting resonant circuit 22, and a transmitting coil 23.
The wireless charging control transmitting circuit 21 is connected with the control unit 12, the output of the wireless charging control transmitting circuit 21 is connected with the wireless charging transmitting resonant circuit 22, and the output of the wireless charging transmitting resonant circuit 22 is connected with the transmitting coil 23. When the control unit 12 starts the wireless charging module 20, the wireless charging control transmitting circuit 21 outputs a transmitting signal, the transmitting signal is processed by the wireless charging transmitting resonant circuit 22 and then transmitted by the transmitting coil 23, and the signal transmitted by the transmitting coil 23 is received by the receiving coil in the target probe, so that the wireless charging of the target probe is realized.
Further optionally, the wireless charging module 20 further includes a charging status indicating device (not shown in fig. 2) connected to the wireless charging control transmitting circuit 21. The charging state indicating device is used for indicating the charging state of the target probe.
Wherein, the charging indicating device may include at least one of a charging buzzer and a charging indicator light. The working time sequence of the charging buzzer and the charging indicator lamp can be set according to actual requirements, and is not limited herein. The working principle of the alarm device can refer to the corresponding description of the alarm buzzer and the alarm indicator lamp, and the description is omitted.
Referring to fig. 2, the working principle of the charging device is described in detail as follows:
the user places the target probe on the charging device, and after the probe in-place detection sensor identifies the target probe, the probe in-place detection sensor outputs a second detection signal and sends the second detection signal to the control unit 12; after receiving the second detection signal, the control unit 12 turns on the wireless charging module 20 to charge the target probe. After the control unit 12 turns on the wireless charging module 20, the wireless charging control transmitting circuit 21 then turns on the wireless charging transmitting resonant circuit 22, the charging buzzer and the charging indicator lamp, respectively. Then, while the target probe is charged, the charging state of the target probe is indicated by the charging buzzer and the charging indicator lamp.
If the probe on-site detection sensor does not detect the target probe, but the alarm sensing sensor detects the target probe, the control unit 12 receives a first detection signal sent by the probe on-site detection sensor and a third detection signal sent by the alarm sensing sensor, which indicate that the target probe is not placed at the correct position of the charging device. The control unit 12 will turn on the alarm control unit and turn off the wireless charging module. After the alarm control unit is turned on, the alarm signal generating circuit 32 can generate 2 different driving signals, namely an alarm buzzer driving signal and an alarm indicator lamp driving signal, and the 2 driving signals respectively turn on the alarm buzzer and the alarm indicator lamp under the action of the alarm signal driving circuit to complete the functions of alarming and indicating.
Referring to fig. 3, the working principle of the charging device is described in detail as follows:
when the probe presence detection sensor identifies the target probe, the probe presence detection sensor sends a second detection signal to the control unit 12 to notify the control unit 12 that the target probe is already in place at this time, but this time, it cannot be said whether the target probe is placed at the correct position of the charging device. Therefore, the control unit 12, after receiving the second detection signal, will automatically determine whether the probe region detection sensor outputs the third detection signal to determine whether the target probe is at the correct position of the charging device. And when the control unit 12 judges that the probe detection sensor outputs the third detection signal, the wireless charging module is started to charge the target probe. After the control unit 12 turns on the wireless charging module 20, the wireless charging control transmitting circuit 21 then turns on the wireless charging transmitting resonant circuit 22, the charging buzzer and the charging indicator lamp, respectively.
If the probe in-place detection sensor detects the target probe and the probe area sensor does not detect the target probe, the control unit 12 determines that the target probe is not placed at the correct position of the charging device, and at this time, the control unit turns on the alarm control unit 30 and turns off the wireless charging module 20. After the alarm control unit 30 is turned on, the alarm signal generating circuit 32 will generate 2 different driving signals, which are an alarm buzzer driving signal and an alarm indicator lamp driving signal, respectively, and the 2 driving signals turn on the alarm buzzer and the alarm indicator lamp under the action of the alarm signal driving circuit 31, respectively, so as to complete the alarm and indication functions.

The target probe is connected with the monitor body, the target probe is used for detecting physiological parameters of a patient, and the monitor body can be used for displaying a detection result of the target probe. When the target probe needs to be charged, the target probe can be charged by the charging device in the embodiment shown in fig. 1-3. The probe detection module in the charging device is used for detecting whether the target probe is in place or not, and when the target probe is not in place, the target probe is stopped to be charged.
