Similarly, it should be appreciated that in the foregoing description of exemplary embodiments of the disclosure, various features of the disclosure are sometimes grouped together in a single embodiment, figure, or description thereof for the purpose of streamlining the disclosure and aiding in the understanding of one or more of the various disclosed aspects. However, the disclosed method should not be interpreted as reflecting an intention that: that is, the claimed disclosure requires more features than are expressly recited in each claim. Rather, as the following claims reflect, disclosed aspects lie in less than all features of a single foregoing disclosed embodiment. Thus, the claims following the detailed description are hereby expressly incorporated into this detailed description, with each claim standing on its own as a separate embodiment of this disclosure.
In the disclosed embodiment, the medical device may include a medical instrument electronic device such as a double click vessel closure device that requires a self-test function in terms of energy output or the like before use. Specifically, taking a bipolar vascular closure device as an example, the bipolar vascular closure device has a special output energy control and regulation mechanism, generally has functions of impedance monitoring and the like, automatically regulates high-frequency output energy through self feedback and control, and is matched with a specially designed closure instrument to act on vascular tissues, so that the bipolar vascular closure device can be used for closing a large-size blood vessel. The bipolar vascular closure device can automatically control energy output and judge whether closure is completed or not, an operator only needs to firmly clamp tissues by using a closure instrument, the system can automatically and continuously output high-frequency energy until closure is completed after output is started, and the operator does not need to manually control energy output and stop. The device will emit a termination tone after the closure is completed and the operator can then perform a mechanical detachment operation. After the device determines that the closure has been completed and issues a termination tone, the device will not output high frequency energy. Bipolar vascular closure devices also have a closure failure cue. During the tissue closing process, when the closing fails due to some reasons (for example, clamping is not firm, an operator releases the handle by mistake, tissue contact is not good, and the like), the device can send a closing failure prompt sound to prompt the operator that the closing is not completely successful, and energy excitation or other treatment needs to be carried out again.
At present, bipolar vascular closure devices are well accepted in the industry and clinic, and the diameter of a reliably closed blood vessel is not more than 7 mm. In actual clinical use, the operator usually does not choose to directly close the larger vessel when handling it, but may consider taking other closing instruments or measures (such as hemostatic clamps, etc.) at the same time, for the protection of the patient. The device is commonly used in clinic at present, and is more used for treating a blood vessel bundle or a tissue bundle with a larger diameter, so that the operation efficiency is improved on the premise of ensuring the safety.
In order to ensure that the bipolar vascular closure device can ensure the accuracy of energy output in clinical application, in the periodic detection process before the device is clinically applied, a device manufacturer needs to designate a qualified technical engineer to perform manual detection, and meanwhile, special tools such as a power meter, a standard resistor, an oscilloscope and the like are matched. Therefore, such periodic inspection schedules significantly increase equipment maintenance costs; moreover, a technical engineer inevitably has operation errors during detection, so that hidden dangers are omitted; meanwhile, various devices can be occupied during device detection, the utilization rate of the devices is reduced, the whole detection process is not accurate enough and timely, and the automation level and the intelligent level are lower.
In order to solve at least one of the problems in the periodic inspection plan of medical equipment such as bipolar vascular closure equipment in the prior art, the present disclosure provides a self-inspection method and apparatus applied to the medical equipment, the medical equipment and a medium.
As shown in fig. 1, a first aspect of the present disclosure provides a self-test method applied to a medical device, which includes steps S101-S103.
In step S101, in response to a power supply voltage detection result, a circuit switching self-test is performed;
in step S102, energy output detection is performed according to a resistance detection result of the circuit switching self-test; and
in step S103, a self-test presentation is performed based on the energy output result of the energy output detection, and the self-test is completed.
The medical device of the embodiment of the present disclosure is generally an electronic apparatus device with an electronic control function, and has a corresponding electronic control circuit. Wherein, the electronic control circuit can also comprise a corresponding self-test circuit. The input power supply voltage of the self-checking circuit can be used as a power supply voltage detection result. After the power supply voltage detection result is obtained, a circuit switching self-test process can be performed. Therefore, the self-checking process can be started each time the equipment is started.
The purpose of the circuit switching self-test can include detection of one or more specific resistors in the circuit to obtain corresponding resistor detection results, and judging energy output of the medical equipment according to the detected resistor detection results, so that the energy output is determined, and energy output detection is realized.
According to the energy output result, self-checking prompt is carried out, so that equipment faults can be found in time, complete self-checking whole-process automation and intellectualization are realized, and the energy output self-checking can be automatically realized every time the equipment is started.
Therefore, the method of the embodiment of the disclosure can accurately judge the output energy, can perform self-checking every time the device is started, finds out the device fault in time, is fully automatic in the whole process, and does not need the participation of technical personnel.

The energy generating device 102 is connected to the energy output circuit 111, and is configured to convert the input ac power of the ac input unit 100 into high-frequency high-voltage power, so as to provide energy input for the energy output circuit 111.

The normal state of the device is a state in which the device in which the circuit is located normally performs a medical function of the device, that is, a normal operation state of the device after the self-test is finished.
The current detection units 1(107) and 2(108) are connected in series in the energy output loop 111, and are used for detecting the current value of the energy output loop 111 in the self-detection process; the voltage detection units 1(109) and 2(110) are connected in parallel to the energy output circuit 111, and are configured to detect a voltage value of the energy output circuit 111 during a self-test process. The output signals of the current detection unit 1(107), the current detection unit 2(108), the voltage detection unit 1(109), and the voltage detection unit 2(110) are analog signals.

The data processing module 103 is connected to the data acquisition module 104, and is configured to receive the digital signal converted by the data acquisition module 104 in real time and perform processing and judgment. In other words, the data processing module 103 can process the current and voltage data corresponding to the digital signal, and accordingly perform the self-test judgment, thereby implementing the self-test automation process.

Fig. 3 schematically illustrates an application scenario corresponding to the self-test method applied to the medical device illustrated in fig. 1 according to an embodiment of the present disclosure.
As shown in fig. 1 to fig. 3, according to the embodiment of the present disclosure, before performing a circuit switching self-test in response to a power supply voltage detection result in step S101, the method further includes:
initializing the medical device in response to the turning on of the alternating current power supply;
and detecting the power supply voltage of the initialized medical equipment to obtain a power supply voltage detection result.
As shown in fig. 2 and 3, in the self-test starting stage, the device turns on the power supply, turns on the ac input unit 100, turns on the ac power supply, and starts the self-test operation, as shown in step S200. Wherein initialization of the device is required before the self-test operation is started. As shown in step S201, in the initialization stage, initialization operations of functions such as IO, data storage, display, and communication are performed to ensure that each function parameter is stable and available.
As shown in fig. 2, the auxiliary power source 101 may convert ac power of the ac input unit 100 to provide dc power for the energy generation device 102, the data processing module 103, and the data acquisition module 104. Further, in order to ensure stable operation of the entire self-test circuit, as shown in step S202, in the auxiliary power source collecting stage, the power source voltage detection result of the auxiliary power source 101 can be obtained by performing power source voltage detection on the auxiliary power source 101 connected to the ac input unit 100. When the power supply voltage detection result is determined to meet the expectation of the corresponding auxiliary power supply 101, it can be ensured that the self-test information or data of the subsequent self-test process is more accurate.
As shown in fig. 1 to 3, in acquiring a power supply voltage detection result according to an embodiment of the present disclosure, the method includes:
and acquiring a power supply voltage detection result according to a first error between the voltage value of the auxiliary power supply and a preset voltage value acquired in the power supply voltage detection process.
In step S203 shown in fig. 3, in the auxiliary power supply determining stage, it is determined whether the auxiliary power supply 101 shown in fig. 2 is abnormal by determining a difference between the voltage value of the auxiliary power supply acquired in the power supply voltage detecting process and a preset voltage value. Specifically, the acquired power supply voltage of the auxiliary power supply 101 may have an error within 3% from the power supply voltage standard value. The power voltage collecting value is the voltage value of the auxiliary power supply, the power voltage standard value is the preset voltage value, and the difference value between the two is a first error value, which can be used to calculate an error rate, where the error rate needs to satisfy the error rate range of 3%. Thus, if the error rate between the collected voltage value and the preset voltage value of the auxiliary power supply 101 exceeds a certain range, it is determined to be abnormal, and an alarm shutdown state of step S208 shown in fig. 3 is entered, and if the error rate is within the set range, the auxiliary power supply is determined to be normal, and then a subsequent self-checking circuit switching stage is entered. Therefore, the judgment of the auxiliary power supply is added for the self-checking process, the stability of the equipment power supply is improved, the detection accuracy of the auxiliary power supply is ensured, and the abnormal or fault position can be confirmed in time.
As shown in fig. 1 to 3, in the step S101 of performing the circuit switching self-test in response to the power supply voltage detection result according to the embodiment of the present disclosure, the method includes:
switching an energy output loop in response to a power supply voltage detection result;
collecting at least two current analog signals and at least two voltage analog signals of an energy output loop, wherein the at least two voltage analog signals correspond to the at least two current analog signals one to one; and
and acquiring an actual resistance value of the energy output loop according to the at least two current analog signals and the at least two voltage analog signals, wherein the actual resistance value is used for determining a resistance detection result of the circuit switching self-test.
As shown in step S204 in fig. 3, in the self-test circuit switching stage, after receiving the power voltage detection result and determining that the auxiliary power supply is normal, the energy output circuit 111 shown in fig. 2 is switched, specifically, the switching device 106 is switched from the open state to the closed state, so that the energy output circuit 111 realizes a path, and the non-inductive resistor 105 is connected to the energy output circuit 111, and after the energy output stage outputs energy stably, the energy output determination in the following step S207 is performed.
After the circuit switching is completed, the energy output stage as shown in step S205 is entered. At this stage, the energy generating device 102 is powered by the auxiliary power source 101 shown in fig. 2, and the energy generating device 102 is connected to the energy output circuit 111 for converting the input ac power of the ac input unit 100 into high-frequency high-voltage power to provide energy input for the energy output circuit 111. The energy output circuit 111 is connected to the non-inductive resistor 105 and the switching device 106, and is used for providing an input and output circuit for outputting energy, thereby performing energy output.
As shown in step S206 of fig. 3, in combination with fig. 2, in the output energy collecting stage, the current detecting unit 1(107) and the current detecting unit 2(108) are connected in series in the energy output circuit 111, and are used for detecting the current value of the energy output circuit 111 in the self-testing process; the voltage detection units 1(109) and 2(110) are connected in parallel to the energy output circuit 111, and are configured to detect a voltage value of the energy output circuit 111 during a self-test process. The data acquisition module 104 may be connected to the current detection unit 1(107), the current detection unit 2(108), the voltage detection unit 1(109), and the voltage detection unit 2(110), respectively, and is configured to receive four different analog signals of the current detection unit 1(107), the current detection unit 2(108), the voltage detection unit 1(109), and the voltage detection unit 2(110) in real time and convert the four different analog signals into digital signals. The current analog signal 1 detected by the current detection unit 1 corresponds to the voltage analog signal 1 detected by the voltage detection unit 1, and the current analog signal 2 detected by the current detection unit 2 corresponds to the voltage analog signal 2 detected by the voltage detection unit 2. Therefore, after the corresponding current and voltage analog signals are converted into digital signals by the data acquisition module 104 and processed by the data processing module 103, the digital signals can be used to determine the resistance value of the actual resistor of the energy output circuit 111. The error between the actual resistance value obtained by detection and the standard value of the non-inductive resistor 105 connected into the energy output loop can determine the resistance detection result of circuit switching self-checking, so that the detection stability of the equipment can be further improved, the self-checking process is ensured to be carried out orderly, the abnormal or fault position can be confirmed in time, and the troubleshooting is convenient to realize.
According to the embodiment of the present disclosure, in the step S101, in response to the power supply voltage detection result, switching the energy output circuit includes:
and responding to the detection result of the power supply voltage, cutting off an external output loop of the medical equipment, and accessing an energy output loop.
As shown in fig. 2 and fig. 3, in the self-test circuit switching phase, if the power voltage detection result is normal, the switching device 106 of the energy output circuit 111 is closed, so that the energy output circuit 111 is turned on, and the non-inductive resistor 105 is connected into the energy output circuit 111, that is, the energy output circuit is connected into the self-test circuit. Meanwhile, an external output loop is disconnected, so that standard medical actions of the equipment are prevented from being executed by misoperation under the condition of incomplete self-checking, and the interference of the self-checking process on normal equipment operation is prevented.
According to the embodiment of the present disclosure, before obtaining an actual resistance value of the energy output circuit according to the at least two current analog signals and the at least two voltage analog signals, where the actual resistance value is used to determine a resistance detection result of the circuit switching self-test, the method further includes:
acquiring a phase difference between actually acquired voltage and actually acquired current of the energy output loop according to the at least two current analog signals and the at least two voltage analog signals;
and determining the resistance of an output load of the energy output loop according to the phase difference, wherein the energy output loop comprises at least one non-inductive resistor.
As shown in fig. 2 and fig. 3, when the output energy collection process in step S206 is completed, the energy output determination stage in step S207 is entered, wherein if the energy output determination is abnormal, the alarm shutdown state in step S208 is entered, and if the energy output determination is normal, the self-check is completed and the self-check is ended, as shown in step S209. In particular, it concerns switching the switching means 106 of the energy output circuit 111 from a closed state to an open state, so that the energy output circuit 111 is disconnected, while ensuring that the external output circuit is accessible, in order to be able to carry out the normal standard medical operation of the device accurately in the next step.
As shown in fig. 2, in the energy output determining stage, the phase difference Δ Φ between the actually detected voltage and the actually detected current of the energy output circuit can be directly obtained according to the digital signals of the voltage and the current processed by the data processing module 103, and accordingly, it is determined whether the non-inductive resistor 105 as the output load of the energy output circuit 111 is a resistive resistor. When the phase difference Δ Φ is 0, the non-inductive resistor 105 is a resistive load, and the energy output judgment result is normal; otherwise, the non-inductive resistor 105 is judged to be a non-resistive resistor, and the energy output judgment result is abnormal.
Therefore, the non-inductive resistor can be used as a load, the output energy is loaded to an energy output loop of the non-inductive resistor, and the data acquisition module is used for acquiring the voltage and the current output by the energy generation device and the corresponding voltage-current phase difference so as to judge whether the energy output is abnormal or not. Therefore, the output energy can be accurately judged, self-detection can be carried out when the bipolar vascular closure device is started every time, the device fault can be found in time, and the self-detection process is fully automatic without the participation of technicians.
As shown in fig. 1 to fig. 3, according to an embodiment of the present disclosure, in obtaining an actual resistance value of an energy output loop according to at least two current analog signals and at least two voltage analog signals, where the actual resistance value is used to determine a resistance detection result of a circuit switching self-test, the method includes:
responsive to the resistance of the output load, converting the at least two current analog signals and the at least two voltage analog signals into corresponding at least two current digital signals and at least two voltage digital signals;
determining an actual resistance value from the at least two current digital signals and the at least two voltage digital signals; and
and obtaining a resistance detection result according to a second error between the actual resistance value and the preset resistance value.
As shown in fig. 2, in the energy output judging stage, after it is determined that the load resistance of the non-inductive resistor 105 is not abnormal, the detected resistance value of the non-inductive resistor 105 may be further compared with the corresponding standard set resistance value, so as to further judge whether the energy output is normal.
Specifically, at least 2 pairs of different current and voltage analog signals, such as the current detection unit 1(107), the current detection unit 2(108), the voltage detection unit 1(109), and the voltage detection unit 2(110), in the energy output loop 111 may be acquired by the data acquisition device 104, and the corresponding current and voltage digital signals are processed by the data processing module 103, so that the actual detection resistance value of the non-inductive resistor 105 in the energy output loop 111 may be determined, specifically as follows:
Z＝V÷I
where Z is an actual detection resistance value of the non-inductive resistor 105, V is an effective voltage value (i.e., an actual detection voltage value) of the energy output circuit 111, and I is an effective current value (i.e., an actual detection current value) of the energy output circuit (111).
Because each non-inductive resistor has a standard set resistance value, and the standard set resistance value (i.e. the preset resistance value) is known, when the actual detection resistance value Z of the non-inductive resistor 105 is compared with the standard set value of the non-inductive resistor 105, the error resistance value between the two is obtained as the second error, and when the second error value is within ± 2 Ω, the energy output can be determined to judge that the normal energy output detection result is normal, the self-detection is finished, otherwise, the abnormal energy output is judged, and the alarm shutdown is performed.
Therefore, the detection stability of the equipment can be further improved, the self-detection process is ensured to be carried out orderly, the abnormal or fault position can be confirmed in time, and troubleshooting is convenient
According to the embodiment of the present disclosure, in the step S102, performing energy output detection according to the resistance detection result of the circuit switching self-test includes:
determining an energy output parameter from the at least two current digital signals and the at least two voltage digital signals;
determining energy output voltage and energy output current according to the energy output parameters;
and determining an energy output result of the energy output detection according to a third error between the energy output voltage and the preset output voltage and a fourth error between the energy output current and the preset output current.
Furthermore, the energy output parameters related to the output energy, such as frequency f, voltage waveform, etc., can be further determined according to the detected and converted current and voltage digital signals. Further, a corresponding energy output voltage and energy output current may be determined from the energy output parameter.
Therefore, whether the energy output result is normal or not is judged according to the magnitude between the energy output voltage and the energy output current and the preset output voltage and output current. And when the energy output result is judged to be normal, namely the required energy output is obtained, the self-checking is finished, and if the energy output result is judged to be abnormal, the alarm is given out and the machine is stopped. The energy output voltage and the energy output current may be the output voltage and the output current of the energy generation device shown in fig. 2.
As shown in fig. 2, the energy generating device 102 may output a fixed output voltage, for example, the energy output is performed under the condition that the standard set resistance value of the non-inductive resistor 105 is known, if a third error between the detected energy output voltage of the energy generating device 102 and the set output voltage of the set energy generating device 102 is within a set voltage error range, it may be determined that the energy output voltage is normal, otherwise, it is abnormal; further, if a fourth error between the detected energy output current of the energy generating device 102 and the set output current of the energy generating device 102 is within a set current error range, it may be determined that the energy output current is normal, otherwise, it is determined that the energy output current is abnormal, and specifically, the current error range may be a deviation of 0.1A. Wherein, the two can only show that the energy output result is judged to be normal under the condition of meeting the normal condition at the same time.
According to the embodiment of the present disclosure, in step S103, performing self-test prompting based on the energy output result of the energy output detection, and completing the self-test includes:
responding to an energy output result of the energy output detection, and prompting and stopping the vehicle;
wherein, the prompt comprises an acoustic prompt, an optical prompt, a code display prompt and an error reporting text prompt.
As shown in step S208 in fig. 3, in the alarm shutdown stage, the fault information may be presented in the form of sound or light, or an error code or an error text may be displayed on the display device to provide the technician with fault information, so that the fault can be located in time, and the fault can be accurately checked.
Therefore, according to the self-checking method disclosed by the embodiment of the disclosure, comprehensive self-checking can be performed after the power supply of the equipment is switched on every time, abnormal faults of the equipment can be found in time, and technicians can quickly troubleshoot the problems according to alarm information after abnormal alarm; in addition, the self-checking process does not need field detection of professional technicians, saves time and trouble and reduces equipment maintenance cost; because the energy output is the main function of medical equipment such as bipolar vascular closure equipment, the accuracy of the energy output plays a crucial factor for the quality of tissue closure, and the reliability and the stability of the equipment can be improved by accurately carrying out self-checking on the output energy.
