Description

Technical Field

[0001] The present invention relates to the field of medical technology, and in particular to a medical device. Background Art

[0002] At present, the reset of medical equipment is generally achieved by using buttons, which is mainly applicable to the scenario where the user actively resets the machine to solve the abnormal operation of the machine. For relatively large bedside monitors, they generally have one or more buttons (or reset holes), and the machine can be shut down or reset by long pressing the button.

[0003] At present, the trend of miniaturization of medical equipment is becoming more and more obvious. Due to the limitation of size and shape, medical equipment may not be able to place a reset button. This situation is particularly prominent in portable monitors. The problem it brings is that users cannot actively reset and can only rely on the monitor's internal processor watchdog and other measures to ensure the reset function. This method has certain risks. In addition, adding a reset button requires considering the waterproof and static protection of medical equipment, which will increase the design complexity of medical equipment. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a medical device with simplified resetting design.

[0005] In order to solve the above technical problems, an embodiment of the present invention provides a medical device, comprising:

[0006] case;

[0007] A power module, the power module is used to provide electrical energy;

[0008] A power module, wherein the power module is configured to perform corresponding operations based on the power provided by the power module;

[0009] A functional interface provided on the housing, the functional interface being configured to realize a predetermined function when connected to a preset external device, the functional interface comprising at least a first pin and a second pin;

[0010] a reset circuit located in the housing, wherein an input end of the reset circuit is connected to at least the first pin, and an output end of the reset circuit is configured to generate a reset signal when the first pin and the second pin are short-circuited in a preset manner;

[0011] The medical device is configured to restore an initial state when the output terminal of the reset circuit generates the reset signal.

[0012] The reset of the medical device in the above-mentioned embodiment is different from the traditional reset by button and the reserved reset hole method. There is no need to add an additional reset button. Active reset can be achieved by using the functional interface that already exists on the medical device. Specifically, when the medical device is abnormal, the user can use tools such as metal tweezers to short-circuit the first pin and the second pin of the functional interface in a preset manner, so that the reset circuit inside the medical device outputs a reset signal, and the medical device can be actively reset. The number of buttons of the above-mentioned medical device is more streamlined, and a button-free design can be achieved, which reduces the complexity of the mechanical and safety design of the medical device.

Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are for making the present application better understood. However, those skilled in the art can easily recognize that some features can be omitted in different situations, or can be replaced by other elements, materials, methods.

[0023] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations.

Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0025] The most important concept of the present invention is to reuse the existing functional interface on the medical device, and by short-circuiting the functional interface, the reset circuit inside the medical device generates a reset signal, thereby resetting the medical device. The above method can complete the reset without setting additional buttons or interfaces on the medical device, reducing the complexity of the mechanical and safety design of the medical device.

[0026] Please refer to Figure 1 In the embodiment shown, a medical device is provided, which includes a housing 10 , a power module 20 , a power consumption module 30 , a functional interface 40 and a reset circuit 50 .

[0027] The power module 20 is used to provide electric energy. In this embodiment, the power module 20 is a rechargeable power module 20. In other embodiments, the power module 20 may also be a non-rechargeable power module 20. The power module 20 may be built into the housing 10, and the power module 20 may be taken out only after the housing 10 is disassembled. The housing 10 may also be provided with a storage compartment for accommodating the power module 20. When the user opens the storage compartment, the power module 20 may be taken out from the medical module, thereby replacing the power module 20.

[0028] The power module 30 is configured to be able to perform corresponding operations based on the power provided by the power module 20. The power module 30 includes some common modules, such as the processor of the medical device, etc. In addition, the power module 30 may be different depending on the medical device. Exemplarily, when the medical device is a monitor, the power module 30 includes but is not limited to a display, a sensor for obtaining monitoring data, and a display, etc.; when the medical device is an ultrasound device, the power module 30 includes but is not limited to an ultrasound probe, etc.; when the medical device is a ventilator, the power module 30 includes but is not limited to a ventilation component, etc.

[0029] The functional interface 40 is provided on the housing 10, and the functional interface 40 is configured to realize a predetermined function when connected to a preset external device. That is to say, the functional interface 40 is originally provided on the medical device in order to realize a certain function. Exemplarily, the functional interface 40 is a charging interface, and the charging interface is used to connect to an external power source, and the power module 20 is charged based on the electric energy provided by the external power source. For example, the medical device is a portable monitor, and the functional interface 40 is a charging interface on the portable monitor; the functional interface 40 can also be a communication interface, and the communication interface is used to transmit data with the external device when connected to a preset external device by wire. For example, the medical device is a central station, and the functional interface 40 is a communication interface on the central station. For another example, the medical device is a monitor, and the monitor communication interface sends the measurement results to other devices; the functional interface 40 can also be a parameter interface, and the parameter interface is used to connect to the sensor component to obtain the parameter signal collected by the sensor component, and the parameter signal includes but is not limited to ECG, RESP, SpO2 and TEMP and other vital sign parameter signals. Each of the above-mentioned functional interfaces 40 includes at least a first pin 41 and a second pin 42, one of which is used for grounding, and some functional interfaces 40 may also include three or more pins. In the following, the functional interface 40 is taken as a charging interface for example.

[0030] The reset circuit 50 is disposed in the housing 10, the input end of the reset circuit 50 is connected to at least the first pin 41, the output end of the reset circuit 50 is configured to generate a reset signal when the first pin 41 and the second pin 42 are short-circuited in a preset manner, and the medical device itself is configured to restore the initial state when the output end of the reset circuit 50 generates the reset signal. That is, when the first pin 41 and the second pin 42 are short-circuited in a preset manner, the medical device is reset.

[0031] Exemplarily, the preset short-circuiting includes short-circuiting for a preset time, for example, the user holds a metal object to short-circuit the first pin 41 and the second pin 42 for 10 seconds, and the reset circuit 50 generates a reset signal. The preset short-circuiting can also be short-circuiting at a set interval to generate a reset signal in the form of a pulse, for example, short-circuiting for 1 second and disconnecting for 1 second for 10 seconds, and the reset circuit 50 generates a reset signal.

[0032] In some embodiments, the medical device further includes a first chip 60, the first chip 60 includes a power input terminal, a power output terminal and a reset input terminal 61, the power input terminal is connected to the charging interface, the power output terminal is connected to the power module 20, Figure 2 The power input terminal is on the left side of the first chip 60, and the power output terminal is on the right side of the first chip 60. The first chip 60 is used to charge the power module 20 based on the power provided by the external power source when the charging interface is connected to the external power source, for example, converting the voltage provided by the external power source into the charging voltage of the power module 20, thereby charging the power module 20.

[0033] The reset input terminal 61 of the first chip 60 is connected to the output terminal of the reset circuit 50. When the first pin 41 and the second pin 42 are short-circuited in a preset manner, the reset input terminal 61 of the first chip 60 will receive the reset signal generated by the output terminal of the reset circuit 50. The first chip 60 is used to control the power module 20 to temporarily stop providing power to at least part of the power module 30 when receiving the reset signal, and then supply power to at least part of the power module 30 again. This process is the re-powering on of the power module 20, and the medical device is reset accordingly.

[0034] In some embodiments, the first chip 60 is a power chip corresponding to the power module 20, and the power chip can manage the charging and discharging of the power module 20, and the model of the power chip is a conventional choice in the art. The present application does not improve the power chip itself, but utilizes the control and management function of the power chip itself, so it is not repeated here. Exemplarily, the reset input terminal 61 is a reset pin of the power chip, and the reset pin can be set to enable the power chip to control the power module 20 to power on again when a high level signal or a low level signal is received. The reset input terminal 61 can also be an enable pin of the power chip, then the reset signal is a signal opposite to the enable signal, for example, if the enable signal is a high level signal, then the reset signal is a low level signal; if the enable signal is a low level signal, then the reset signal is a high level signal.

[0035] In some embodiments, when the medical device includes the first chip 60, the reset circuit 50 includes a unidirectional conductive element 51 and a pull-up resistor 52, the reset signal is a low-level signal, and the preset short-circuit mode is a short-circuit for a preset duration.

[0036] The first end of the unidirectional conductive member 51 is connected to the first pin 41, and the second end of the unidirectional conductive member 51 is connected to the reset input terminal 61 of the first chip 60. The unidirectional conductive member 51 is configured to allow current to flow from the second end of the unidirectional conductive member 51 to the first end of the unidirectional conductive member 51. It can be seen that the unidirectional conductive member 51 can control the unidirectional flow of current to avoid the influence of the charging voltage backflow on the reset signal. Exemplarily, the unidirectional conductive member 51 is a diode, the anode of the diode is the second end of the unidirectional conductive member 51, and the cathode of the diode is the first end of the unidirectional conductive member 51. The first end of the pull-up resistor 52 is connected to the power module 20, and the second end of the pull-up resistor 52 is connected to the reset input terminal 61. In this case, the junction point of the second end of the pull-up resistor 52 and the second end of the unidirectional conductive member 51 is equivalent to the output end of the reset circuit 50. The following is based on Figures 2 to 4 The figure illustrates the resetting process of the medical device, wherein the dotted arrow indicates the direction of the current and × indicates that the current is blocked.

[0037] like Figure 2 As shown, the charging interface is in a suspended state at this time. The first end of the unidirectional conductive member 51 is equivalent to being disconnected and having an infinite potential, and the second end of the unidirectional conductive member 51 is set to a high level through the action of the power module 20 and the pull-up resistor 52. At this time, the reset circuit 50 is equivalent to outputting a high level signal to the reset input terminal 61.

[0038] like Figure 3 As shown, the charging interface is connected to the external power supply. The external power supply charges the power module 20 through the first chip 60. Due to the unidirectional conduction characteristics of the unidirectional conduction member 51, the external power supply will not affect the potential of the second end of the pull-up resistor 52 and the second end of the unidirectional conduction member 51. At this time, the reset circuit 50 is still equivalent to outputting a high level signal to the reset input terminal 61.

[0039] like Figure 4 As shown, at this time, the first pin 41 and the second pin 42 are short-circuited in a preset manner. The first end of the unidirectional conductive member 51 is equivalent to a short circuit and the potential is infinitely small. The potential of the first end of the unidirectional conductive member 51 is lower than the potential of the second end, and the unidirectional conductive member 51 is thus turned on to generate a voltage drop. The second end of the unidirectional conductive member 51 and the second end of the pull-up resistor 52 are pulled down to close to 0V. For example, if a Schottky diode is used as the unidirectional conductive member 51, the second end of the pull-up resistor 52 is close to 0.2V. At this time, the reset circuit 50 is equivalent to outputting a low-level signal to the reset input terminal 61, so that the first chip 60 controls the power module 20 to power on again.

[0040] In some embodiments, Figure 5As shown, the reset circuit 50 further includes a delay circuit 53, the input end of the delay circuit 53 is respectively connected to the second end of the unidirectional conductive member 51 and the second end of the pull-up resistor 52, that is, the input end of the delay circuit 53, the second end of the unidirectional conductive member 51 and the second end of the pull-up resistor 52 have the same combined potential. The output end of the delay circuit 53 is connected to the reset input end 61, so the output end of the delay circuit 53 is equivalent to the output end of the reset circuit 50, and the delay circuit 53 is used to output the level of its own input end from its own output end after delay. For example Figure 5 As shown, at this time, the first pin 41 and the second pin 42 are short-circuited in a preset manner, the first end of the unidirectional conductive member 51 is equivalent to a short circuit and the potential is infinitely small, and the potential of the first end of the unidirectional conductive member 51 is lower than the potential of the second end, so that the second end of the unidirectional conductive member 51 and the second end of the pull-up resistor 52 are pulled down to close to 0V. Figure 4 The difference is that when the junction of the input end of the delay circuit 53, the second end of the unidirectional conductor 51 and the second end of the pull-up resistor 52 changes to a low level, the output end of the delay circuit 53 does not immediately change to a high level, but changes to a high level after a period of time.

[0041] Different from the medical device including the first chip 60, in some embodiments, the medical device includes a second chip 70, and the second chip 70 includes a power input terminal, a power output terminal, a power input terminal and a reset input terminal 71, for example Figure 6 The power input terminal and the power supply input terminal are both on the left side of the second chip 70, and the power output terminal and the reset input terminal 71 are on the right side of the second chip 70. The power input terminal is connected to the charging interface, and the power output terminal and the power supply input terminal are both connected to the power module 20. The second chip 70 is used to charge the power module 20 based on the power provided by the external power supply when the charging interface is connected to the external power supply. For example, the voltage provided by the external power supply is converted into the charging voltage of the power module 20, so as to charge the power module 20. The power supply input terminal is used to receive power from the power module 20 to enable the second chip 70 to work. It can be seen that one of the differences between the second chip 70 and the first chip 60 is that the second chip 70 is powered by the power module 20. If the power of the power module 20 is completely exhausted, the second chip 70 will stop working.

[0042] The reset input terminal 71 of the second chip 70 is connected to the output terminal of the reset circuit 50. The reset input terminal 71 is set to be set to the first level after the power input terminal receives the power from the power module 20. When the first pin 41 and the second pin 42 are short-circuited in a preset manner, the output terminal of the reset circuit 50 sets the reset input terminal 71 to the second level to generate a reset signal input to the reset input terminal 71. The second chip 70 is used to control the power module 20 to temporarily stop providing power to at least part of the power module 30 when receiving the reset signal, and then re-supply power to at least part of the power module 30, so that the medical device returns to the initial state. It can be seen that the difference between the second chip 70 and the first chip 60 also includes: the second chip 70 itself can set the reset input terminal 71 to the first level. After the first pin 41 and the second pin 42 are short-circuited in a preset manner, the output terminal of the reset circuit 50 sets the reset input terminal 71 to the second level different from the first level, thereby generating a reset signal.

[0043] In some embodiments, the second chip 70 is a charging chip corresponding to the power module 20, and the charging chip can manage the charging and discharging of the power module 20, and the model of the charging chip is a conventional choice in the art. The present application does not improve the charging chip itself, but utilizes the control and management function of the charging chip itself, so it is not repeated here. Exemplarily, the reset input terminal 71 is a reset pin of the charging chip. After the charging chip receives the power supply of the power module 20 at the power input terminal, the reset pin is set to the first level. When the reset pin is set to the second level, the charging chip controls the power module 20 to power on again. The reset input terminal 71 can also be an enable pin of the charging chip. After the charging chip receives the power supply of the power module 20 at the power input terminal, the enable pin is set to the first level. When the enable pin is set to the second level, the charging chip controls the power module 20 to power on again.

[0044] In some embodiments, the reset circuit 50 includes a unidirectional conductive element 51, the first level is a high level, the second level is a low level, and the preset short-circuit mode is a short-circuit for a preset duration.

[0045] The first end of the unidirectional conductive member 51 is connected to the first pin 41, and the second end of the unidirectional conductive member 51 is connected to the reset input terminal 71 of the second chip 70. The unidirectional conductive member 51 is configured to allow current to flow from the second end of the unidirectional conductive member 51 to the first end of the unidirectional conductive member 51. It can be seen that the unidirectional conductive member 51 can control the unidirectional flow of current to avoid the influence of the charging voltage backflow on the reset signal. In this case, the second end of the unidirectional conductive member 51 is equivalent to the output end of the reset circuit 50. Exemplarily, the unidirectional conductive member 51 is a diode, the anode of the diode is the second end of the unidirectional conductive member 51, and the cathode of the diode is the first end of the unidirectional conductive member 51. Figures 6 to 8The figure illustrates the resetting process of the medical device, wherein the dotted arrow indicates the direction of the current and × indicates that the current is blocked.

[0046] like Figure 6 As shown, the charging interface is in a suspended state at this time. The first end of the unidirectional conductive member 51 is equivalent to being disconnected and having an infinite potential, the reset input terminal 71 of the second chip 70 is equivalent to being suspended and having a high level, and the potential of the second end of the unidirectional conductive member 51 is the same as that of the reset input terminal 71 and is also at a high level.

[0047] like Figure 7 As shown, at this time, the charging interface is connected to the external power supply. The external power supply charges the power module 20 through the second chip 70. Due to the unidirectional conduction characteristics of the unidirectional conduction member 51, the external power supply will not affect the level of the reset input terminal 71 of the second chip 70. The reset input terminal 71 of the second chip 70 is still equivalent to being suspended at a high level, and the potential of the second end of the unidirectional conduction member 51 is the same as that of the reset input terminal 71 and is also at a high level.

[0048] like Figure 8 As shown, at this time, the first pin 41 and the second pin 42 are short-circuited in a preset manner. The first end of the unidirectional conductive member 51 is equivalent to a short circuit and the potential is infinitely small. The potential of the first end of the unidirectional conductive member 51 is lower than the potential of the second end. The unidirectional conductive member 51 is thus turned on to generate a voltage drop, and the second end of the unidirectional conductive member 51 is changed from a high level to a low level, so that the reset input terminal 71 of the second chip 70 is also pulled down to close to 0V. For example, a Schottky diode is used as the unidirectional conductive member 51, and the reset input terminal 71 of the second chip 70 is close to 0.2V. At this time, the reset input terminal 71 of the second chip 70 is changed from a high level to a low level, which is equivalent to the reset circuit 50 outputting a reset signal to the reset input terminal 71, so that the second chip 70 controls the power module 20 to power on again.

[0049] In some embodiments, the second chip 70 itself has a delay mechanism, which is equivalent to integrating the delay circuit 53 inside the chip. The chip with a delay mechanism is a common type of chip in the art, so it will not be described in detail here. Figure 8 In the embodiment, after the second end of the unidirectional conductive element 51 changes from a high level to a low level, the reset input terminal 71 of the second chip 70 will not be immediately pulled down to close to 0V, but will only change to a low level after the second end of the unidirectional conductive element 51 changes to a low level for a period of time.

[0050] In some embodiments, Fig. 9As shown, the reset circuit 50 includes a microprocessor 54, and the microprocessor 54 includes one or more output terminals. The input terminal of the microprocessor 54 is at least connected to the first pin 41. The microprocessor 54 is used to generate a reset signal at at least one output terminal of the microprocessor 54 after a preset time length after the first pin 41 and the second pin 42 are short-circuited. The advantages of using the microprocessor 54 in the reset circuit 50 are: ① For the generation of the reset signal, a more flexible preset short-circuit mode can be set. For example, it is set that when a specific pulse signal generated by the first pin 41 and the second pin 42 are short-circuited at intervals, the microprocessor 54 generates a reset signal at the output terminal. The above method can avoid improper reset of the medical device due to accidental short-circuiting; ② Compared with setting a fixed delay circuit 53, the delay time can be flexibly set in the microprocessor 54 by programming; ③ Similarly, through programming, the microprocessor 54 can more flexibly set the number of reset signals output.
