Description

technical field

The embodiments of the present application relate to the technical field of medical equipment, and in particular to a perfusion method and device for an ablation target of a perfusion pump, a perfusion pump and a storage medium.

Background technique

During the clinical surgical operation, the surgical site (ablation target) will have some pollutants such as excised tissue, bleeding, exudate and high temperature. At this time, a medical perfusion pump is required to control the surgical site Infusing a specific liquid for real-time cleaning and cooling, this kind of medical perfusion pump has high requirements on the temperature and flow rate of the perfusate.

The flow rate of the infusion pump is adjusted according to the temperature of the ablation target. The larger the flow rate, the more heat will be taken away, and the faster the temperature will drop. When the temperature is high, the flow rate of the perfusion pump needs to be increased, and when the ablation target temperature is lowered, the flow rate of the perfusion pump needs to be decreased. The usual practice is to directly adjust the flow rate of the perfusion pump according to the temperature. If the temperature is too high, the flow rate will be increased, and if the temperature is too low, the flow rate will be reduced. This method often leads to untimely cooling, causing the temperature of the ablation target to rise suddenly and sharply. Even if the flow rate is maximized at this time, the temperature of the ablation site cannot be lowered immediately, which will bring discomfort to the patient and even bring risks to the patient's operation. .

FIG. 1 is a flow chart of an implementation method for an ablation target perfusion of a perfusion pump provided by an embodiment of the present application. As shown in Figure 1, the method specifically includes:

Step S101, receiving a request for perfusing an ablation target.

The embodiment of the present application can be applied to a perfusion pump, specifically, a medical perfusion pump, so as to perfuse an ablation target with a corresponding perfusate. The ablation target may be human or animal tissue perfused by the perfusion pump, for example, the surgical site of a surgical patient. The request for perfusing the ablation target may be directly input by the user operating the perfusion pump, or may be triggered and generated when the ablation target is detected to exceed a preset temperature, thereby improving the utilization efficiency of the perfusion pump.

Step S102 , perfusing the ablation target using a preset perfusion manner in the current perfusion cycle according to the request.

In the embodiment of the present application, a preset perfusion method is used to perfuse the ablation target in each perfusion cycle, until the perfusion end request input by the user is received. When using the preset perfusion method to perfuse the ablation target in the current perfusion cycle according to the perfusion request, as shown in Figure 2, the following steps are included:

Step S201 , using a preset first flow rate to perfuse the ablation target for a first preset duration.

Step S202 , using the preset second flow rate to perfuse the ablation target for a second preset duration, wherein the sum of the first preset duration and the second preset duration is equal to the duration of the current perfusion cycle.

In this embodiment of the present application, the execution order of steps S201 and S202 is not limited, that is, step S201 may be executed first, and then step S202 may be executed; or step S202 may be executed first, and then step S201 may be executed.

In the embodiment of the present application, the first flow rate and the second flow rate are different, and the first flow rate may be greater than the second flow rate, or may be less than the second flow rate. Preferably, when the first flow rate is greater than the second flow rate, the first flow rate is the maximum output flow rate of the perfusate in the perfusion pump, and the second flow rate is the minimum output flow rate of the perfusate in the perfusion pump; when the first flow rate is less than the second flow rate , the first flow rate is the minimum output flow rate of the perfusate in the perfusion pump, and the second flow rate is the maximum output flow rate of the perfusate in the perfusion pump. As the flow rate is high, the heat taken away will be more, and the temperature will drop faster, and the flow rate will be smaller, the heat taken away will be smaller, and the temperature will drop more slowly. The flow rate is alternately perfused, so that the temperature of the ablation target is in a suitable range, and the temperature will not rise sharply, which simplifies the control process of the perfusion temperature of the perfusion pump, and achieves better control of the ablation target temperature.

Considering that the temperature of different ablation targets will be different, in order to improve the accuracy of temperature control, before perfusing the ablation target, the duration of the current perfusion cycle, the first flow rate, the second flow rate, the first The preset duration and the second preset duration are set to accurately perfuse the ablation target. The sum of the first preset duration and the second preset duration is equal to the duration of the current perfusion cycle, which can ensure periodic perfusion and ablation target The accuracy of temperature control, so that the perfusion can be adjusted in time when the temperature changes.

In this embodiment of the present application, when the ablation target is perfused with the preset perfusion method in the current perfusion cycle according to the perfusion request for the ablation target, the ablation target is perfused for the first preset duration with the preset first flow rate. The set second flow rate performs perfusion on the ablation target for a second preset duration, wherein the sum of the first preset duration and the second preset duration is equal to the duration of the current perfusion cycle, so that within one perfusion cycle, the first flow rate The perfusion and the perfusion of the ablation target at the second flow rate are alternated so that the temperature of the ablation target is in an appropriate range and the temperature will not rise sharply, which simplifies the control process of the perfusion temperature of the perfusion pump and at the same time achieves a better temperature control of the ablation target. control.

Fig. 3 is a flow chart of the realization of the ablation target perfusion method of the perfusion pump provided by another embodiment of the present application. As shown in Figure 3, the method specifically includes:

Step S301 , using a preset first flow rate to perfuse the ablation target for a first preset duration.

Step S302 , using the preset second flow rate to perfuse the ablation target for a second preset duration, wherein the sum of the first preset duration and the second preset duration is equal to the duration of the current perfusion cycle.

The embodiment of the present application can be applied to a perfusion pump, specifically, a medical perfusion pump, so as to perfuse an ablation target with a corresponding liquid. In the embodiment of the present application, a preset perfusion method is used to perfuse the ablation target in each perfusion cycle, until the perfusion end request input by the user is received. Specifically, the ablation target is perfused for a first preset duration by using a preset first flow rate, and the ablation target is perfused for a second preset duration by using a preset second flow rate. The sum of the first preset duration and the second preset duration is equal to the duration of the current perfusion cycle.

In this embodiment of the present application, considering that the temperature of different ablation targets will be different, in order to improve the accuracy of temperature control, before using the preset first flow rate to perfuse the ablation target for the first preset duration, you can Set the duration of the current perfusion cycle, the first flow rate, the second flow rate, the first preset duration, and the second preset duration according to the ablation target, so as to accurately perfuse the ablation target. The first preset duration and the second preset duration The sum of the time lengths is equal to the time length of the current perfusion cycle, which can ensure the periodic perfusion and the accuracy of the ablation target temperature control, so that the perfusion can be adjusted in time when the temperature changes.

Step S303, acquiring the temperature of the ablation target.

In the embodiment of the present application, the detection of the temperature of the ablation target is always performed in real time, so as to acquire the temperature change of the ablation target in time. For example, the preset temperature sensor can detect the temperature of the ablation target in real time, so that the device implementing this step (such as the processor in the perfusion pump) can obtain the temperature of the ablation target from the temperature sensor.

In one embodiment, the embodiment of the present application can adjust the first preset duration (that is, the duration of perfusion with the first flow rate) and the second preset duration (that is, the duration of perfusion with the second flow rate) within the cycle time according to the temperature of the ablation target. Perfusion time).

A specific method for adjusting the ratio is introduced below through steps S304-S306 (taking the first flow rate greater than the second flow rate as an example).

Step S304 , judging whether the temperature of the ablation target is greater than the upper limit of the preset temperature range, if yes, execute step S305 , otherwise execute step S306 .

In one embodiment, after acquiring the temperature of the ablation target, it is judged whether the temperature is greater than the upper limit of the preset temperature range, if yes, step S305 is performed, otherwise, step S306 is performed. Wherein, the preset temperature range is a normal temperature range of the ablation target.

Step S305 , increasing the first preset duration, and entering the next perfusion cycle, so as to perfuse the ablation target in a preset perfusion manner.

In the embodiment of the present application, since the duration of each perfusion cycle is the same, this step increases the first preset duration and decreases the second preset duration. That is to say, the present application increases the first preset duration, that is, increases the proportion of the first preset duration in the perfusion cycle, and decreases the proportion of the second preset duration in the perfusion cycle.

In one embodiment, when the acquired temperature of the ablation target is greater than the upper limit of the preset temperature range, it indicates that the current temperature of the ablation target is too high. Go to step S301 to continue to perfuse the ablation target, so that after entering the next perfusion cycle, increase the duty cycle of the perfusion time of the first flow rate in the next perfusion cycle to lower the temperature of the ablation target steadily. Wherein, the duty cycle can be understood as the proportion of the perfusion time of the first flow rate in the cycle time.

In one embodiment, when increasing the first preset duration, the formula p1=(t1-t2)/t2 can be used to calculate the increase ratio of the first preset duration in the next perfusion cycle, where p1 represents the increase ratio, and t1 Indicates the acquired temperature of the ablation target, t2 indicates the upper limit of the preset temperature range, and then increases the first preset duration according to the increase ratio, for example, the formula S=S1*(1+p1) can be used to calculate the increased second A preset duration, S represents the increased first preset duration, and S1 represents the first preset duration under the current perfusion cycle. If the increased first preset duration is greater than or equal to the duration of the current perfusion cycle, then the increased first preset duration can be set as the duration of the perfusion cycle, that is, the second perfusion cycle will be used throughout the next perfusion cycle. A flow rate perfuses the ablation target.

Step S306, judging whether the temperature of the ablation target is lower than the lower limit of the preset temperature range, if yes, execute step S307, otherwise jump to step S301;

In the embodiment of the present application, when the temperature of the ablation target is lower than the lower limit of the preset temperature range, it indicates that the current temperature of the ablation target is too low, and step S307 is executed at this time. If the temperature of the ablation target is not less than the lower limit of the preset temperature range, that is, the temperature of the ablation target is within the preset temperature range, jump to step S301, that is, directly enter the next perfusion cycle, so that the same as the previous cycle The perfusion speed and the corresponding perfusion time duty cycle continue to perfuse the ablation target.

Step S307 , reducing the first preset duration, and entering the next perfusion cycle, so as to perfuse the ablation target in a preset perfusion manner.

In the embodiment of the present application, since the duration of each perfusion cycle is the same, this step reduces or shortens the first preset duration while increasing the second preset duration. That is to say, the present application reduces the first preset duration, that is, reduces the proportion of the first preset duration in the perfusion cycle, and increases the proportion of the second preset duration in the perfusion cycle.

In one embodiment, when the temperature of the ablation target is lower than the lower limit of the preset temperature range, it indicates that the current temperature of the ablation target is too low. At this time, the first preset duration is reduced or shortened to enter the next perfusion cycle, and skip Go to step S301 to continue to perfuse the ablation target, so that after entering the next perfusion cycle, reduce the duty cycle of the perfusion time of the first flow rate in the next perfusion cycle, and increase the temperature of the ablation target steadily. Specifically, when reducing the first preset duration, the formula p2=(t3-t4)/t4 can be used to calculate the reduction ratio of the first preset duration in the next perfusion cycle, where p2 represents the reduction ratio, and t3 represents the acquisition The temperature of the ablation target, t4 represents the lower limit value of the preset temperature range, after that, the first preset duration is reduced according to the reduction ratio, for example, the formula S'=S1*(1+p2) can be used to calculate the reduced first The preset duration, S' represents the reduced first preset duration, and S1 represents the first preset duration under the current perfusion cycle. If the reduced first preset time length is less than or equal to zero, the reduced first preset time length can be set to zero at this time, that is, the second flow rate is used to perfuse the ablation target throughout the next perfusion cycle.

In the embodiment of the present application, within a period of time, the ablation target is perfused with a preset first flow rate for a first preset duration, and the ablation target is perfused with a preset second flow rate for a second preset duration, Wherein, the sum of the first preset duration and the second preset duration is equal to the duration of the current perfusion cycle, and the temperature of the ablation target is acquired in real time during the perfusion cycle, when the acquired temperature of the ablation target is greater than the upper limit of the preset temperature range , increase the first preset duration to increase the duty ratio of the perfusion time of the first flow rate in the next perfusion cycle, so that after entering the next perfusion cycle, the temperature of the ablation target will be lowered steadily. When the temperature of the ablation target When it is less than the lower limit of the preset temperature range, reduce the first preset duration to reduce the duty cycle of the perfusion time of the first flow rate in the next perfusion cycle, so that the temperature of the ablation target will be stabilized after entering the next perfusion cycle. go up.

In another embodiment of the present application, the first flow rate is lower than the second flow rate. In the current perfusion cycle, the ablation target may be perfused at the minimum flow rate (first flow rate), and then ablated at the maximum flow rate (second flow rate). The target is perfused, that is to say, the ablation target is perfused for the first preset duration using the preset first flow rate, and then the ablation target is perfused for the second preset duration using the preset second flow rate, wherein, The sum of the first preset duration and the second preset duration is equal to the duration of the current perfusion cycle. When the acquired temperature of the ablation target is greater than the upper limit of the preset temperature range, the first preset duration is reduced (meaning that the second preset duration is increased), and the next perfusion cycle is entered to use the preset perfusion method for ablation The target is perfused, and in the next perfusion cycle, the perfusion time of the maximum flow rate is increased, and the perfusion time of the minimum flow rate is decreased, so as to achieve a steady decrease in the temperature of the ablation target. When the temperature of the ablation target is less than the lower limit of the preset temperature range, increase the first preset duration, and enter the next perfusion cycle, so as to perfuse the ablation target with the preset perfusion method, and in the next perfusion cycle, The perfusion time of the maximum flow rate is reduced, and the perfusion time of the minimum flow rate is increased, so as to realize the steady rise of the ablation target temperature.
