Technical Field
The application relates to the field of medical equipment, in particular to a part protection method and equipment of a therapeutic apparatus and the therapeutic apparatus.
Background
In the field of medical instruments, a shock wave device is generally connected with a balloon catheter filled with liquid (generally, normal saline and a contrast agent are mixed and configured according to a certain proportion) by adopting a pulse control board card, and the pulse control board card outputs high-voltage pulses to electrodes in the balloon catheter. Under the action of high-voltage pulse, the liquid in the gap of electrode channel generates liquid-electric effect, and the generated shock wave breaks up calcified lesion to attain the goal of treatment.
In general, the balloon is pressed and expanded in order to ensure that the balloon is fully attached to a target blood vessel after being fully expanded and to keep a certain safe distance between the balloon wall and an electrode (aiming at ensuring that effective shock wave energy is generated and avoiding the balloon from being too close to the electrode and being subjected to discharge thermal erosion). However, the balloon should not be pressurized too high, otherwise, there is a risk of rupture prior to RBP during discharge, causing serious complications such as serious inflammation, embolism, dissection, etc., and there may be cases where the electrodes discharge in the blood. Therefore, the balloon internal pressure needs to be known in time when the balloon is pressurized. The related art is that the saccule is pressurized by a pressurizing pump, and medical staff determines the pressure inside the saccule by visually observing a pressure dial plate on the pressurizing pump. However, in the actual clinical procedure, the pressure is increased beyond the preset safety range due to misoperation of an operator or imperfect vasodilatation, so that the internal pressure of the balloon is insufficient and the therapeutic effect cannot be achieved, or the internal pressure of the balloon exceeds the standard to break the balloon, cause complications such as embolism and the like, and even discharge in blood.

In the field of medical instruments, a therapeutic apparatus is generally connected with a balloon catheter filled with liquid (generally, normal saline and a contrast agent are mixed and configured according to a certain proportion) and outputs high-voltage pulses to electrodes in the balloon catheter. Under the action of high-voltage pulse, the liquid in the gap of electrode channel generates liquid-electric effect, and the generated shock wave can break up calcified lesion so as to attain the goal of curing. In order to ensure that the saccule is fully attached to the blood vessel of the target area after being fully expanded and ensure that the wall of the saccule keeps a certain safe distance from the electrode (aiming at ensuring the generation of effective shock wave energy and avoiding the saccule from being too close to the electrode and being thermally corroded by discharge), the saccule can be punched and expanded. However, the balloon should not be over pressurized, otherwise, there is a risk of rupture prior to the RBP during discharge, causing serious complications such as inflammation, embolism, dissection, etc., and there may be cases where the electrodes are discharged in the blood. Therefore, the balloon internal pressure needs to be known in time when the balloon is pressurized. The related art is that the saccule is pressurized by a pressurizing pump, and medical staff determines the pressure inside the saccule by visually observing a pressure dial plate on the pressurizing pump. However, in the actual clinical process, the pressurization is increased to exceed the preset safety range due to misoperation of an operator or unsatisfactory vasodilation, so that the balloon cannot be fully expanded to achieve the treatment effect because the internal pressure of the balloon is insufficient, or the balloon is broken because the internal pressure of the balloon exceeds the standard, complications such as embolism are caused, and even discharge occurs in blood.
In view of the above problems, the embodiments of the present application provide a method for protecting components of a therapeutic apparatus, which can protect target components and a patient from being damaged.
The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Referring to fig. 1, it is a schematic flow chart of the method for protecting components of the therapeutic apparatus according to the embodiment of the present application, which mainly includes steps S101 to S105, and is described as follows:
step S101: a communication connection is established with the pressure sensor.
In order to acquire data from the pressure sensor, a communication connection between the main control board of the therapeutic apparatus and the pressure sensor needs to be established, and the communication connection can be a wired communication connection, namely a communication connection formed by a data line connection, or a wireless communication connection. In order to avoid the data line from being stumbled, the wireless communication connection between the main control board and the pressure sensor can be established.
When the communication connection between the main control board and the pressure sensor is wireless communication connection, in order to further maintain the reliability of the wireless communication connection, the method of the application further comprises: controlling a heartbeat time for sending a heartbeat message to the pressure sensor; and starting timing from the last heartbeat message, and sending the heartbeat message to the pressure sensor through the wireless communication connection when the timing reaches the heartbeat time. Although the heartbeat messages enable the two communication parties to know whether the communication connection is disconnected in time, the heartbeat messages are frequently sent through the communication connection when the heartbeat messages do not need to be sent, and especially when the heartbeat messages do not need to be sent, not only bandwidth resources are occupied, but also power consumption of devices is increased, and therefore in the above embodiment, the heartbeat time for sending the heartbeat messages to the pressure sensor needs to be controlled.
As an embodiment of the present application, the heartbeat time for controlling sending the heartbeat message to the pressure sensor may be: determining a first heartbeat sending interval according to the reference heartbeat time; and determining a second heartbeat sending interval in the working state of the pressure sensor according to the first heartbeat sending interval and the reference heartbeat time. The reference heartbeat time in the above embodiment may be a preset minimum value of a heartbeat sending interval between the main control board and the pressure sensor, and correspondingly, determining the first heartbeat sending interval according to the reference heartbeat time may be: and calculating a tentative heartbeat interval by taking the minimum value of the heartbeat sending interval as a basic value, increasing the interval duration every time on the basis, trying to communicate with the pressure sensor by adopting the tentative heartbeat interval until the communication tried by the tentative heartbeat interval is successful, and determining the tentative heartbeat interval before the next tentative heartbeat interval is greater than the maximum value of the reference heartbeat time, wherein the tentative heartbeat interval is determined as the first heartbeat sending interval, or determining the tentative heartbeat interval before the communication failure is tried as the first heartbeat sending interval until the communication tried by the tentative heartbeat interval is failed, wherein the maximum value of the reference heartbeat time is included in a plurality of reference heartbeat times, and the maximum value of the reference heartbeat time can be the maximum value of the heartbeat sending intervals of other devices which are connected with the main control board and are in the same area range as the pressure sensor.
As for determining the second heartbeat sending interval in the working state of the pressure sensor according to the first heartbeat sending interval and the reference heartbeat time, the second heartbeat sending interval in the working state of the pressure sensor may be calculated and obtained according to the first heartbeat sending interval, the minimum value of the heartbeat sending interval, and the heartbeat value determination strategy corresponding to the working state of the pressure sensor. In the above embodiment, the heartbeat value determining strategy is to determine the working state of the pressure sensor according to the operating condition of the medical staff on the main control board and/or the pressure sensor, and further determine a reasonable heartbeat value, that is, determine which level of heartbeat interval to use according to the operating condition of the medical staff. In principle, the more frequent the medical personnel operate, the smaller the heartbeat transmission interval; conversely, the longer the medical personnel are inoperable, the larger the heartbeat transmission interval can be adopted.
In order to timely acquire abnormal conditions such as disconnection of the communication connection between the main control board and the pressure sensor and the like, and take corresponding measures, in the embodiment, the difference value between the current moment and the latest heartbeat success moment of the pressure sensor can be calculated; if the difference value between the current moment and the latest heartbeat success moment of the pressure sensor is not smaller than the second heartbeat sending interval, the wireless communication connection with the pressure sensor is determined to be disconnected, so that medical personnel or an operator can be reminded to take corresponding measures, and the main control board and the pressure sensor are enabled to reestablish the wireless communication connection. It should be noted that the latest heartbeat success time may be a time when a message sent by the pressure sensor is received last time by the current time.
Step S102: and acquiring the pressure value inside the conduit monitored by the pressure sensor in real time through the established communication connection, wherein the conduit is communicated with the target component.
In embodiments of the application, the target component, i.e. the component of the apparatus to be protected, e.g. the balloon of the shock wave device when the apparatus is a shock wave device, is in communication with the catheter. The catheter is internally filled with a mixed solution consisting of the prepared physiological saline and the contrast agent. When the pressure sensor monitors the pressure value inside the conduit, the pressure value can be transmitted to the main control board in real time through the communication connection between the pressure sensor and the main control board, so that the main control board can acquire the pressure value inside the conduit monitored by the pressure sensor in real time through the established communication connection. It should be noted that the main control board obtains the pressure value inside the catheter monitored by the pressure sensor in real time through the established communication connection, and the pressure sensor may continuously monitor the pressure value inside the catheter and transmit the pressure value to the main control board in real time before the target component is placed into the body, that is, when the mixed liquid of the saline and the contrast agent contained in the catheter is pressurized, or after the target component is placed into the body. As described above, since the catheter communicates with the target member such as the balloon via the mixture solution of the saline and the contrast medium, the pressure value inside the catheter, which is monitored by the pressure sensor, is also the pressure value applied to the balloon.
In one embodiment of the present application, the pressure sensor is disposed inside the conduit, and accordingly, the pressure value inside the conduit monitored by the pressure sensor obtained in real time through the established communication connection may be: when the manual pressurizing equipment pressurizes the conduit, the pressure value inside the conduit monitored by the pressure sensor is received in real time through communication connection. For an operator, since the manual pressurizing device has certain requirements on operation, in order to prevent the pressure sensor from falling off from the manual pressurizing device or other accidents, the pressure sensor is more suitable to be arranged in the conduit; even if the pressure sensor is suitably provided inside the catheter, the catheter is communicated with the target member such as the balloon through a mixture solution of the saline and the contrast medium, and therefore, the pressure value inside the catheter monitored by the pressure sensor is also the pressure value borne by the target member such as the balloon.
In another embodiment of the present application, the conduit is communicated with an automatic pressurizing device, the pressure sensor is disposed at a pressure output portion of the automatic pressurizing device, and accordingly, the pressure value inside the conduit monitored by the pressure sensor obtained in real time through the established communication connection may be: when the automatic pressurizing equipment pressurizes the conduit, the pressure value of the pressure output part of the automatic pressurizing equipment monitored by the pressure sensor is received in real time through communication connection and is used as the pressure value inside the conduit. After the automatic pressurizing equipment is started, the pressurizing process generally does not need human intervention, and when the pressure sensor is arranged at the pressure output part of the automatic pressurizing equipment, for example, the pressure sensor is adhered to a pressure output hose of the automatic pressurizing equipment, on one hand, an operator does not need to move the automatic pressurizing equipment, and the pressure sensor can be prevented from falling off from the automatic pressurizing equipment or from other accidents; on the other hand, when the pressure sensor is not arranged in the conduit, the trouble of operation is avoided, so that when the pressurizing device is an automatic pressurizing device and the conduit is communicated with the automatic pressurizing device, the pressure sensor can be arranged at the pressure output part of the automatic pressurizing device. Because the catheter is communicated with the automatic pressurizing equipment and the catheter is communicated with the balloon and other target components, the pressure value of the pressure output part of the automatic pressurizing equipment, which is monitored by the pressure sensor, can be used as the pressure value inside the catheter and also used as the pressure value born by the balloon and other target components.
Step S103: and determining the relation between the pressure value inside the conduit monitored by the pressure sensor and a preset range.
In the embodiment of the application, the preset range is a range in which a target component such as a balloon is communicated with a catheter through a mixed solution of physiological saline and a contrast agent through a clinical experiment, and when the catheter is pressurized, the balloon is fully expanded but not broken, and the internal pressure value of the catheter is the preset range, that is, the preset range is a range in which the therapeutic effect of the therapeutic apparatus can be achieved and the pressure of the target component such as the balloon is within a safe value. Generally, the predetermined range may be 4 to 6 standard atmospheres, i.e., the predetermined range is [4,6] atm. It is possible to use only one pressure sensor to monitor the pressure value inside the conduit and determine the relationship of this single pressure sensor to the preset range. In order to further increase the reliability of the monitoring, redundant pressure sensors may also be provided in the exemplary embodiment of the present application, for example, two pressure sensors, namely a first pressure sensor and a second pressure sensor, may be provided in the conduit or at the pressure output of the automatic pressurizing device. Accordingly, determining the relationship of the pressure value inside the conduit monitored by the pressure sensor to the preset range may be: and determining the relation between the pressure value inside the conduit monitored by the pressure sensor and the preset range by comparing the pressure value inside the conduit monitored by the first pressure sensor with the preset range and comparing the pressure value inside the conduit monitored by the second pressure sensor with the preset range.
Specifically, as an embodiment of the present application, by comparing the pressure value inside the conduit monitored by the first pressure sensor with the preset range and comparing the pressure value inside the conduit monitored by the second pressure sensor with the preset range, the relationship between the pressure value inside the conduit monitored by the pressure sensor and the preset range may be determined as follows: if the absolute difference value between the pressure value inside the conduit monitored by the first pressure sensor and the preset range is not more than the first preset difference threshold value and/or the pressure value inside the conduit monitored by the second pressure sensor and the preset rangeAnd if the absolute difference value of the preset range is not greater than the first preset difference value threshold, determining that the pressure value inside the conduit monitored by the pressure sensor is within the preset range, otherwise, determining that the pressure inside the conduit monitored by the pressure sensor is not within the preset range. The absolute difference between the conduit internal pressure value monitored by the first pressure sensor or the second pressure sensor and the preset range may be obtained by subtracting the left end point value and the right end point value of the preset range from the conduit internal pressure value monitored by the first pressure sensor or the second pressure sensor, and taking an absolute value from the subtraction result, or may be obtained by subtracting an average value of the left end point value and the right end point value of the preset range from the conduit internal pressure value monitored by the first pressure sensor or the second pressure sensor, and taking an absolute value from the subtraction result. For example, the first pressure sensor or the second pressure sensor monitors the pressure value inside the conduit asPThe preset range is [, ]Pl，Pr]I.e. left end point value ofPlRight endpoint value isPrIf the absolute difference value between the pressure value inside the conduit monitored by the first pressure sensor or the second pressure sensor and the preset range isP- Pl |、|P-PrL or L P- (Pl +Pr)/2|。
As another embodiment of the present application, by comparing the pressure value inside the conduit monitored by the first pressure sensor with the preset range and comparing the pressure value inside the conduit monitored by the second pressure sensor with the preset range, it may be determined that the relationship between the pressure value inside the conduit monitored by the pressure sensor and the preset range is: calculating an absolute difference value between the pressure value in the conduit monitored by the first pressure sensor and the pressure value in the conduit monitored by the second pressure sensor to obtain a pressure absolute difference value; if the absolute difference value of the pressures is not greater than a second preset difference threshold value, whether the absolute difference values of the pressure values in the conduit monitored by the first pressure sensor and the second pressure sensor and the preset range are respectively greater than a first preset difference threshold value or not is judged; if the absolute difference values between the pressure values in the guide pipe monitored by the first pressure sensor and the second pressure sensor and the preset range are not larger than the first preset difference threshold value, determining that the pressure value in the guide pipe monitored by the pressure sensor is within the preset range, and otherwise, determining that the pressure value in the guide pipe monitored by the pressure sensor is not within the preset range. According to the principle of liquid fluidity, when two pressure sensors are simultaneously arranged at the same depth of the same liquid, the pressure values measured by the two pressure sensors are supposed to be the same or similar, therefore, if the absolute difference value of the pressures obtained in the above embodiment is not greater than the second preset difference threshold value, it is indicated that both the first pressure sensor and the second pressure sensor can be normally used, otherwise, if the absolute difference value of the pressures obtained in the above embodiment is greater than the second preset difference threshold value, it is indicated that one of the pressure sensors may have a fault. On the premise that the absolute difference value of the pressure obtained in the above embodiment is not greater than the second preset difference threshold, it is determined whether the absolute difference values between the pressure values inside the conduit monitored by the first pressure sensor and the second pressure sensor and the preset ranges are not greater than the first preset difference threshold. As for the method for determining whether the absolute difference between the pressure values inside the conduit monitored by the first pressure sensor and the second pressure sensor and the preset range is not greater than the first preset difference threshold, reference may be made to the related description of whether the absolute difference between the pressure value inside the conduit monitored by the first pressure sensor and the preset range is not greater than the first preset difference threshold and/or whether the absolute difference between the pressure value inside the conduit monitored by the second pressure sensor and the preset range is not greater than the first preset difference threshold in the foregoing embodiment, which is not described herein again.
Step S104: if the pressure value in the conduit is within the preset range, the discharging control module of the therapeutic apparatus executes the discharging action.
If the pressure value in the catheter is within the preset range, the pressure bearing of target components such as the saccule and the like is moderate, so that the discharge control module of the therapeutic apparatus can execute the discharge action. Fig. 2a is a schematic diagram of a discharging control module with an impedance detection chip 203 according to an embodiment of the present disclosure. The anode 205 of the high-voltage pulse discharge circuit, the first single-pole double-throw switch 201, the target component 204, the second single-pole double-throw switch 202, the resistor 206 and the triode 207 form a working loop. When the pressure value in the conduit is detected to be within the preset range, the discharge control module executes a discharge action, that is, a high-voltage pulse released by the high-voltage pulse discharge circuit enables the target component 204 to generate a liquid-electric effect in an electrode channel gap, thereby generating a shock wave, by turning on the movable end 13 and the second immovable end 12 of the first single-pole double-throw switch 201, connecting the movable end 13 of the first single-pole double-throw switch 201 with the first end of the target component 204, connecting the movable end 23 of the second single-pole double-throw switch 202 with the second end of the target component 204, and turning on the movable end 23 and the second immovable end 22 of the second single-pole double-throw switch 202, and pressing down a discharge switch (or a discharge trigger button on an operation panel) of a therapeutic apparatus such as a shock wave device. It should be noted that, in the discharge control module illustrated in fig. 2a, it is not necessary to have the impedance detection chip 203, that is, the first stationary terminal 11 of the first single-pole double-throw switch 201 and the first stationary terminal 21 of the second single-pole double-throw switch 202 are both connected to "ground" (i.e., zero potential), as shown in fig. 2b, a schematic diagram of a discharge control module provided in another embodiment of the present application is shown.
Step S105: if the pressure value in the conduit is not within the preset range, a working circuit formed by the discharge control module and the target component is cut off, and an alarm instruction is sent out.
If the pressure value in the catheter is not within the preset range, the pressure bearing of target components such as the balloon is insufficient or exceeds the standard, and therefore the main control board is required to cut off a working loop formed by the discharge control module and the target components and send an alarm instruction. As for a specific cut-off method, taking the discharge control module illustrated in fig. 2a as an example, the moving terminal 13 and the second stationary terminal 12 of the first single-pole double-throw switch 201 may be disconnected and/or the moving terminal 23 and the second stationary terminal 22 of the second single-pole double-throw switch 202 may be disconnected, as shown in fig. 3a to 3c, so as to cut off the working loop formed by the discharge control module and the target component.
It can be known from the method for protecting components of the therapeutic apparatus illustrated in fig. 1 that, unlike the related art, the method determines the pressure inside the balloon by observing a pressure dial provided on a pressure pump with naked eyes, so that the pressure inside the balloon is difficult to observe accurately, and therefore, the pressure inside the balloon is insufficient and cannot achieve a therapeutic effect or exceeds the internal pressure of the balloon, so that the balloon is broken and complications such as embolism are caused.
