The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
Example 1
The present embodiment 1 provides a control system of a thermal infusion treatment device, which in one embodiment, specifically, as shown in fig. 2, may include a variable speed peristaltic pump 1, an infusion tube, and a heating tank 3; the variable speed peristaltic pump 1 may comprise a pump head and a drive; the infusion catheter may comprise a first catheter 21 and a second catheter 22. Wherein, one end of the first conduit 21 and one end of the second conduit 22 can be hermetically arranged in the heating tank body 3, the other end of the first conduit 21 can be inserted into the human body cavity 4, and the other end of the second conduit 22 can be inserted into the human body cavity 4; or may be connected by a connecting tube led out from the body lumen, which is not limited herein. The pump head may be crimped onto the first conduit 21, or the pump head may be crimped onto the second conduit 22. As a person skilled in the art, it is understood that the implementation principle of a peristaltic pump is similar to: the fluid filled hose is pinched with a finger and the fluid in the tube can be moved toward one end as the finger is slid forward (squeezed). The peristaltic pump utilizes the principle to replace fingers with pump heads (rollers), and the pump heads continuously and alternately extrude the infusion catheter so as to form negative pressure in the catheter, thereby realizing the flow of fluid in the catheter. Moreover, the fluid can flow in different directions by changing the rotation direction of the pump head.
In one embodiment, a user can set a certain preset time-varying signal to the variable speed peristaltic pump 1, and the driving device can be used for receiving the preset time-varying signal, specifically, the preset time-varying signal can include a direction time-varying signal, and the direction time-varying signal can include a positive direction signal and a negative direction signal; it should be noted that, the positive direction signal or the negative direction signal may also be used to instruct the driving device to control the pump head to rotate in the positive direction within a certain preset time period, or to control the pump head to rotate in the negative direction within a certain preset time period. Specifically, the driving device may be configured to control the pump head to rotate in the positive direction within a first preset time period T1 according to the positive direction signal, where the first preset time period T1 may be 10min, 15min, or the like, and is not limited herein and may be selected according to an actual situation. So that the liquid medicine can flow into the first conduit 21 from the heating tank 3 after the heating tank 3 is heated and enter the human body cavity 4 from the other end of the first conduit 21, flow into the second conduit 22 from the human body cavity 4 and flow back to the heating tank 3 from the second conduit 22 by rotating and extruding the first conduit 21 or the second conduit 22 by the pump head within the first preset time period of 10min, and the liquid medicine can circulate in the positive direction.
After the liquid medicine passes through the first conduit 21 and enters the human body cavity 4, the liquid medicine not only scours the wall of the cavity channel, but also contacts other human organs, on one hand, the human organs can form obstacles to the liquid medicine and can form a column-winding vortex as shown in fig. 1, so that the liquid medicine in the rear area of the column-winding vortex cannot be sufficiently replaced, and the liquid medicine cannot effectively scour the rear area; and after the liquid medicine enters the body cavity, the liquid medicine is contacted with the visceral organs except the cavity channel wall, and the liquid medicine is in a heat dissipation state due to the large contact surface, so that the temperature difference exists between the liquid medicine entering the body and the liquid medicine exiting the body, the cavity channel wall close to one end of the exiting body and the visceral organs are not easy to contact the liquid medicine close to the controlled temperature, the heating is not sufficient and uniform, and the treatment effect is poor. In order to solve the above problem, after the first preset time period T1, the driving device may be configured to control the pump head to rotate in a reverse direction within a second preset time period T2 according to a reverse direction signal, where the second preset time period T2 may be 5min or 10min, and the like, and by rotating and pressing the first catheter 21 or the second catheter 22 through the pump head, the medical liquid may flow from the heating tank 3 into the second catheter 22 after being heated in the heating tank 3, and enter the body lumen 4 from the other end of the second catheter 22, and flow from the body lumen 4 into the first catheter 21, and flow back from the first catheter 21 to the heating tank 3, and circulate the medical liquid in a reverse direction, so that the medical liquid may enter the body lumen 4 through the second catheter 22 after the first preset time period T1, so that the high temperature medical liquid flows from the second catheter 22, thereby breaking a laminar flow and achieving sufficient replacement of the high temperature medical liquid and the low temperature medical liquid, the full heating of the cavity wall and the visceral organs is realized; the second catheter 22 can make the liquid medicine flush the back side of the viscera as shown in figure 1, so that the area which is not heated sufficiently under the column-winding vortex is heated sufficiently, and the treatment effect on the patient is improved.
In one embodiment, the driving device may include a PLC Controller (Programmable Logic Controller) and a driving motor, and the driving motor may be a servo motor, or the like; the pump head may be mounted on an output shaft (not shown) of the drive motor. The user can burn preset time-varying signals into the PLC in advance, and the PLC can control an output shaft of a driving motor (such as a servo motor) to rotate in different directions or control the output shaft of the driving motor to rotate at different speeds according to the preset time-varying signals stored in advance.
In one embodiment, the time-varying direction signal may include a positive direction signal and a negative direction signal. Specifically, the PLC controller may be configured to control the driving motor to rotate in the positive direction within a first preset time period T1 according to the positive direction signal, so that the output shaft of the driving motor drives the pump head to control the liquid medicine to flow into the first conduit 21 from the heating tank 3, enter the body lumen 4 from the other end of the first conduit 21, flow into the second conduit from the body lumen, and flow back to the heating tank from the second conduit, and make the liquid medicine circulate in the positive direction; after the first preset time period T1, the PLC controller may be further configured to control the driving motor to rotate in a reverse direction within a second preset time period T2 according to the reverse direction signal, so that the output shaft of the driving motor drives the pump head to control the medical fluid to flow from the heating tank 3 into the second conduit 22, enter the body lumen 4 from the other end of the second conduit 22, flow from the body lumen 4 into the first conduit 21, and flow from the first conduit 21 back into the heating tank 3, and circulate the medical fluid in the reverse direction. So, can realize getting into human inner chamber through the second pipe with the liquid medicine through PLC controller control driving motor to the liquid medicine can be to erodeing behind the internal organs as shown in figure 1, and can make originally be heated insufficient region fully and be heated around the post vortex down, improve the treatment to the patient.
In an application scenario, a pressure pump used in the existing thermal perfusion treatment equipment performs pressure control on the liquid medicine, wherein the speed of the pressure pump is usually kept constant, the liquid medicine is easy to form a laminar flow at a low flow rate, as shown in fig. 3, so that the low-temperature fluid on the wall-attached layer cannot be sufficiently replaced, and the replacement speed of the liquid medicine is slow, so that the fluid temperature gradually decreases from an outlet of the inner cavity of the human body to the inner wall through the infusion catheter, and the temperature of the liquid medicine actually contacted with the inner wall and the human viscera is lower than the temperature of the liquid medicine entering the body or even the temperature of the liquid medicine exiting the body, and an ideal treatment effect cannot be achieved. In order to solve the above technical problem, in one embodiment, the preset time varying signal may further include a speed ramping signal, wherein the speed ramping signal may be used for instructing the PLC controller to control the driving motor to achieve uniform variable speed rotation in different times. Specifically, as shown in fig. 5, the PLC controller may be configured to control the driving motor to perform uniform acceleration rotation in the positive direction, uniform rotation in the positive direction, and uniform deceleration rotation in the positive direction at different time intervals within a first preset time interval T1 according to the direction time-varying signal and the speed ramp signal until the speed of the driving motor is uniformly decelerated to zero; the PLC controller may further be configured to control the driving motor to perform uniform acceleration rotation in an opposite direction, uniform rotation in an opposite direction, and uniform deceleration rotation in an opposite direction respectively at different time intervals within a second preset time interval T2 according to the direction time varying signal and the speed ramping signal until the speed of the driving motor is uniformly decelerated to zero. In this embodiment, it can be understood that, by controlling the driving motor to perform the forward uniform acceleration rotation, the forward uniform rotation and the forward uniform deceleration rotation in different time intervals of the first preset time interval T1, and controlling the driving motor to perform the reverse uniform acceleration rotation, the reverse uniform rotation and the reverse uniform deceleration rotation in different time intervals of the second preset time interval T2, respectively, the pump head can drive the liquid medicine to form turbulent flow in the inner cavity 4 of the human body while the liquid medicine washes the back side of the visceral organ as shown in fig. 1, so that the laminar flow formed on the surface of the cavity channel can be destroyed, which is favorable for the replacement of the liquid medicine in the cavity of the human body.
As will be understood by those skilled in the art, turbulent flow is a state of flow in a fluid, and when the flow velocity increases from a certain velocity to a certain predetermined value, the flow lines in the fluid are no longer clearly distinguishable, and the flow field of the fluid has many small vortices, as shown in fig. 4, in particular, the turbulent flow can be called turbulent flow, turbulent flow or turbulent flow, etc. In the above embodiment, the variable speed peristaltic pump 1 can control the liquid medicine to form turbulent flow according to the direction time varying signal and the speed varying signal, so as to destroy the laminar flow of the liquid medicine generated on the inner wall of the body cavity and outside the viscera, realize the replacement of the low temperature liquid medicine by the liquid medicine forming the turbulent flow, and improve the temperature of the liquid medicine contacting the inner cavity of the human body, thereby performing effective treatment.
In one embodiment, as shown in fig. 5, the first preset period T1 and the second preset period T2 are one time period, wherein the PLC controller may be configured to control the driving motor to rotate for a plurality of time periods according to the direction time varying signal and the speed ramping signal. That is, the PLC controller may control the driving motor to perform the cyclic uniform acceleration rotation in the forward direction, uniform deceleration rotation in the forward direction, uniform acceleration rotation in the reverse direction, uniform rotation in the reverse direction, and uniform deceleration rotation in the reverse direction, respectively, at different time intervals within a plurality of time periods.

In one embodiment, the preset time-varying signal may further include a velocity non-uniform signal; wherein the speed non-uniform signal can be used to instruct the PLC controller to control the driving motor to achieve non-uniform variable speed rotation at different times. As shown in fig. 7, the PLC controller may be configured to control the driving motor to perform non-uniform acceleration rotation in the positive direction, uniform rotation in the positive direction, and non-uniform deceleration rotation in the positive direction at different time intervals within a first preset time interval T1 according to the direction time varying signal and the speed non-uniform varying signal until the speed of the driving motor is non-uniformly decelerated to zero; the PLC controller may be further configured to control the driving motor to perform reverse non-uniform acceleration rotation, reverse uniform rotation, and reverse non-uniform deceleration rotation at different time intervals within a second preset time interval T2 according to the direction time varying signal and the speed non-uniform signal until the speed of the driving motor is non-uniformly decelerated to zero. In the above embodiment, the variable speed peristaltic pump 1 can control the liquid medicine to form turbulent flow according to the direction time varying signal and the speed non-uniform signal, so as to destroy the laminar flow of the liquid medicine generated on the inner wall of the body cavity and the outside of the organs, realize the replacement of the low temperature liquid medicine by the liquid medicine forming the turbulent flow, and increase the temperature of the actual liquid medicine, thereby performing effective treatment.
In one embodiment, specifically, as shown in fig. 7, the first preset period T1 and the second preset period T2 are one time cycle; the PLC is used for controlling the driving motor to rotate for a plurality of time periods according to the direction time-varying signal and the speed non-uniform signal.
