The flow rate of the perfusion pump is regulated according to the temperature of the ablation target, the flow rate is high, the more heat is taken away, the faster the temperature is reduced, the less the flow rate is, the slower the temperature is reduced, when the temperature of the ablation target is overhigh, the flow rate of the perfusion pump needs to be increased, and when the temperature of the ablation target is reduced, the flow rate of the perfusion pump needs to be reduced. It is common practice to directly adjust the perfusion pump flow rate according to temperature, with too high a temperature increasing the flow rate and too low a temperature decreasing the flow rate.

Detailed Description

For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Fig. 1 is a flowchart of an implementation of an ablation target perfusion method of an perfusion pump according to an embodiment of the present application. As shown in fig. 1, the method specifically includes:

step S101, a request for pouring the ablation target is received.

The embodiment of the application can be applied to a perfusion pump, in particular to a medical perfusion pump, so as to perfuse an ablation target by using corresponding perfusate. The ablation target may be a human or animal tissue perfused by an perfusion pump, for example, a surgical site of a surgical patient. The request for pouring the ablation target can be directly input by a user operating the pouring pump, or can be generated by triggering when the ablation target is detected to exceed the preset temperature, so that the utilization efficiency of the pouring pump is improved.

Step S102, pouring the melting target in the current pouring period by using a preset pouring mode according to the request.

In the embodiment of the application, the melting target is perfused in each perfusion period by using a preset perfusion mode until the perfusion is ended when a perfusion ending request input by a user is received. When the melting target is perfused in the current perfusion period according to the perfusion request by using a preset perfusion mode, as shown in fig. 2, the method comprises the following steps:

step 201, performing perfusion on an ablation target for a first preset duration by using a preset first flow rate.

Step S202, performing perfusion on the ablation target for a second preset time period by using a preset second flow rate, wherein the sum of the first preset time period and the second preset time period is equal to the time period of the current perfusion period.

In the embodiment of the present application, the execution sequence of steps S201 and S202 is not limited, and step S201 may be executed first, and then step S202 may be executed; alternatively, step S202 may be performed first, and then step S201 may be performed.

In this 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 perfusate pump, and the second flow rate is the minimum output flow rate of the perfusate in the perfusate pump; when the first flow rate is smaller 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. Because the flow rate is big, the heat of taking away is much, and the temperature drops faster, and the flow rate is little, and the heat of taking away is little, and the temperature drops slower, the embodiment of the application is in a perfusion period with first flow rate, with second flow rate alternate perfusion for the temperature of ablation target is in suitable scope, and the temperature can not rise sharply, has simplified the control process of perfusion pump perfusion temperature, has realized the better control of ablation target temperature.

In order to improve the accuracy of temperature control, before the ablation target is perfused, the time length of the current perfusion period, the first flow rate, the second flow rate, the first preset time length and the second preset time length can be set according to the ablation target so as to accurately perfuse the ablation target, the sum of the first preset time length and the second preset time length is equal to the time length of the current perfusion period, and the accuracy of the perfusion periodic performance and the ablation target temperature control can be ensured, so that the perfusion is adjusted in time when the temperature changes.

According to the method and the device, when the ablation target is perfused in a current perfusion period in a preset perfusion mode according to a request for perfusing the ablation target, the first preset duration is used for perfusing the ablation target, the second preset duration is used for perfusing the ablation target, and the sum of the first preset duration and the second preset duration is equal to the duration of the current perfusion period, so that the ablation target is perfused in one perfusion period at the first flow rate and at the second flow rate respectively, and the temperature of the ablation target is in a proper range in such a way alternately, the temperature cannot be increased sharply, the control process of the perfusion temperature of the perfusion pump is simplified, and meanwhile, the better control of the temperature of the ablation target is realized.

Fig. 3 is a flowchart illustrating an implementation of an ablation target infusion method of an infusion pump according to another embodiment of the present application. As shown in fig. 3, the method specifically includes:

step S301, performing perfusion on an ablation target for a first preset duration by using a preset first flow rate.

Step S302, perfusion is carried out on the ablation target for a second preset time period by using a preset second flow rate, wherein the sum of the first preset time period and the second preset time period is equal to the time period of the current perfusion period.

The embodiment of the application can be applied to a perfusion pump, in particular to a medical perfusion pump, so as to perfuse an ablation target with corresponding liquid. In the embodiment of the application, the melting target is perfused in each perfusion period by using a preset perfusion mode until the perfusion is ended when a perfusion ending request input by a user is received. Specifically, the ablation target is irrigated for a first preset duration by using a preset first flow rate, and the ablation target is irrigated 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 period.

In the embodiment of the application, in consideration of different temperatures of the ablation targets, before the ablation targets are perfused for a first preset time period by using the preset first flow rate, the duration of the current perfusion period, the first flow rate, the second flow rate, the first preset time period and the second preset time period can be set according to the ablation targets so as to accurately perfuse the ablation targets, the sum of the first preset time period and the second preset time period is equal to the duration of the current perfusion period, and the accuracy of the perfusion periodic performance and the ablation target temperature control can be ensured, so that the perfusion is adjusted in time when the temperature changes.

Step S303, acquiring the temperature of the ablation target.

In the embodiment of the application, the detection of the temperature of the ablation target is always performed in real time, so that the temperature change condition of the ablation target is timely obtained. For example, a preset temperature sensor may detect the temperature of the ablation target in real time, so that a device implementing the procedure (e.g., a processor in the infusion pump) may acquire the temperature of the ablation target from the temperature sensor.

In one embodiment, the proportion of the first preset duration (i.e. the duration of the perfusion with the first flow rate) and the second preset duration (i.e. the duration of the perfusion with the second flow rate) in the period time may be adjusted according to the temperature of the ablation target.

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

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

In one embodiment, after the temperature of the ablation target is obtained, it is determined whether the temperature is greater than the upper limit value of the preset temperature range, if yes, step S305 is performed, otherwise step S306 is performed. Wherein the preset temperature range is a temperature range of an ablation target under normal conditions.

Step S305, increasing a first preset duration, and entering a next pouring period to pour the melting target in a preset pouring manner.

In this embodiment of the present application, since the duration of each perfusion period is the same, the first preset duration is increased and the second preset duration is reduced in this step. That is, the present application increases the first preset time period, that is, increases the proportion of the first preset time period in the perfusion period, and decreases the proportion of the second preset time period in the perfusion period.

In one embodiment, when the obtained temperature of the ablation target is greater than the upper limit value of the preset temperature range, the current temperature of the ablation target is indicated to be too high, the first preset time period is increased, the next infusion period is entered, and the step S301 is skipped to continue to infuse the ablation target, so that after the next infusion period is entered, the duty cycle of the infusion time of the first flow rate in the next infusion period is increased, and the temperature of the ablation target is steadily reduced. The duty cycle is understood to mean the proportion of the perfusion time of the first flow rate that is present in the period duration.

In one embodiment, when the first preset time period is increased, an increase ratio of the first preset time period in the next perfusion period may be calculated by using a formula p1= (t 1-t 2)/t 2, where p1 represents the increase ratio, t1 represents the acquired temperature of the ablation target, t2 represents the upper limit value of the preset temperature range, and then the first preset time period is increased according to the increase ratio, for example, the increased first preset time period may be calculated by using a formula s=s1×1+p1, S represents the increased first preset time period, and S1 represents the first preset time period under the current perfusion period. If the increased first preset time length is greater than or equal to the duration of the current perfusion period, the increased first preset time length can be set to be the duration of the perfusion period, that is, the ablation target is perfused by using the first flow rate in the whole period of the next perfusion period.

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

in the embodiment of the present application, when the temperature of the ablation target is less than the lower limit value of the preset temperature range, it indicates that the current temperature of the ablation target is too low, and step S307 is performed. If the temperature of the ablation target is not less than the lower limit value of the preset temperature range, that is, the temperature of the ablation target is within the preset temperature range, the step S301 is skipped, that is, the next perfusion cycle is directly entered, so that the perfusion speed and the corresponding perfusion time duty ratio which are the same as those of the previous cycle continue to perfuse the ablation target.

Step S307, the first preset time period is reduced, and the next pouring period is entered to pour the melting target in a preset pouring mode.

In this embodiment of the present application, since the duration of each perfusion period is the same, the step reduces or shortens the first preset duration and increases the second preset duration. That is, the present application decreases the first preset time period, that is, decreases the proportion of the first preset time period in the perfusion period, and increases the proportion of the second preset time period in the perfusion period.

In one embodiment, when the temperature of the ablation target is less than the lower limit value of the preset temperature range, the current temperature of the ablation target is indicated to be too low, the first preset time period is reduced or shortened, the next infusion period is entered, and the step S301 is skipped to continue to infuse the ablation target, so that after the next infusion period is entered, the duty cycle of the infusion time of the first flow rate in the next infusion period is reduced, and the temperature of the ablation target is smoothly raised. Specifically, when the first preset time period is reduced, a reduction ratio of the first preset time period in the next perfusion period may be calculated by using a formula p2= (t 3-t 4)/t 4, where p2 represents the reduction ratio, t3 represents the acquired temperature of the ablation target, t4 represents the lower limit value of the preset temperature range, and then the first preset time period is reduced according to the reduction ratio, for example, the reduced first preset time period may be calculated by using a formula S '=s1× (1+p2), S' represents the reduced first preset time period, and S1 represents the first preset time period under the current perfusion period. If the reduced first preset duration is less than or equal to zero, the reduced first preset duration may be set to zero at this time, i.e., the ablation target is perfused using the second flow rate throughout the next perfusion cycle.

In the embodiment of the application, in a period duration, a preset first flow rate is used for carrying out first preset duration of perfusion on an ablation target, and a preset second flow rate is used for carrying out second preset duration of perfusion on the ablation target, wherein the sum of the first preset duration and the second preset duration is equal to the duration of a current perfusion period, the temperature of the ablation target is obtained in real time in the perfusion period, when the obtained temperature of the ablation target is greater than the upper limit value of a preset temperature range, the first preset duration is increased, the duty ratio of the perfusion time of the first flow rate in the next perfusion period is increased, so that the temperature of the ablation target is steadily reduced after the next perfusion period is entered, and when the temperature of the ablation target is smaller than the lower limit value of the preset temperature range, the first preset duration is reduced, the duty ratio of the perfusion time of the first flow rate in the next perfusion period is reduced, and the temperature of the ablation target is steadily increased after the next perfusion period is entered.

In another embodiment of the present application, the first flow rate is less than the second flow rate, and the ablation target may be perfused at a minimum flow rate (first flow rate) during the current perfusion period, and then perfused at a maximum flow rate (second flow rate), that is, the ablation target is perfused at a first preset time period using the preset first flow rate, and then perfused at a second preset time period using the preset second flow rate, where the sum of the first preset time period and the second preset time period is equal to the time period of the current perfusion period. When the obtained temperature of the ablation target is greater than the upper limit value of the preset temperature range, the first preset duration is reduced (meaning that the second preset duration is increased), and the next perfusion period is entered to perfuse the ablation target in a preset perfusion mode, wherein the perfusion time of the maximum flow rate is increased and the perfusion time of the minimum flow rate is reduced in the next perfusion period, so that the stable reduction of the temperature of the ablation target is realized. When the temperature of the ablation target is smaller than the lower limit value of the preset temperature range, the first preset duration is increased, the next perfusion period is entered to perfuse the ablation target in a preset perfusion mode, the perfusion time of the maximum flow rate is reduced, and the perfusion time of the minimum flow rate is increased in the next perfusion period, so that the stable rising of the temperature of the ablation target is realized.
