Description

Technical Field

[0001] The present application relates to the field of medical device technology, and in particular to a perfusion drainage system and a control method. Background Art

[0002] As a common acute and severe disease in neurosurgery, intraventricular hemorrhage has a very high risk of disability and death. The overall mortality rate is 43%-83%. External Ventricular Drain (EVD) is a procedure that places drainage tubes into the ventricles, which can drain hematomas and hydrocephalus caused by obstructed cerebrospinal fluid circulation in the ventricles, relieve intracranial hypertension, reduce the occurrence of vasospasm and cytotoxic effects, and improve patient symptoms. However, the holes of the drainage tubes after EVD surgery may be blocked by blood clots, resulting in blockage and poor drainage. Therefore, additional surgery may be required to replace the drainage tubes, increasing patient pain, treatment costs and infection risks. Therefore, it is particularly important to prevent blockage during the drainage process.

[0003] Related technologies usually reduce intracranial pressure by placing drainage tubes to directly drain cerebrospinal fluid in the ventricles. Medical staff are required to regularly observe the changes in the amount of fluid collected in the drainage bag and regularly perform manual intracranial pressure monitoring to determine whether there is a tube blockage. When a tube blockage occurs, medical staff are required to manually push liquid to clear the blocked drainage tube and complete the perfusion drainage. However, this manual monitoring and clearing method is cumbersome to operate. Summary of the invention

[0004] In order to solve the problem of complicated perfusion and drainage operation in the prior art, the present application provides a perfusion and drainage system and a control method.

[0005] In the first aspect, the present application provides a perfusion drainage system, which adopts the following technical solution: A perfusion and drainage system, comprising: a perfusion unit, a drainage unit, an interactive control unit and a drainage tube; The interactive control unit is used to obtain intracranial pressure parameters and drainage volume parameters of the patient's ventricles, dynamically determine the current perfusion and drainage mode according to the intracranial pressure parameters and the drainage volume parameters, and generate a control instruction corresponding to the current perfusion and drainage mode, wherein the current perfusion and drainage mode is one of a normal perfusion and drainage mode, a dredging mode and a drainage mode, and the dredging mode is used to remove the blockage of the drainage tube; The drainage tube is used to connect the perfusion unit and the drainage unit to the patient's cerebral ventricle respectively; The perfusion unit and the drainage unit are used to receive control instructions sent by the interactive control unit, and perform perfusion and / or drainage on the patient's ventricle according to the control instructions.

[0006] By adopting the above technical solution, different patients and conditions may require different perfusion and drainage strategies. The interactive control unit dynamically determines the current perfusion and drainage mode according to the intracranial pressure parameters and the drainage volume parameters, generates corresponding control instructions, realizes personalized treatment, and improves the treatment effect. The perfusion unit and drainage unit connected to the patient's ventricle through the drainage tube perform perfusion and / or drainage according to the control instructions, which reduces human intervention, simplifies the perfusion and drainage control process, and improves the treatment efficiency.

[0007] In a preferred example, the present application may be further configured as follows: the perfusion unit includes a perfusion passage switch and a perfusion fluid bag, and the drainage unit includes a drainage passage switch and a drainage bag; The perfusion liquid bag is used to perfuse liquid into the patient's cerebral ventricle when the perfusion passage is open; The drainage bag is used to drain the fluid in the patient's cerebral ventricle when the drainage passage switch is turned on.

[0008] By adopting the above technical solution, the perfusion unit and the drainage unit respectively realize precise control of the perfusion and drainage processes through the perfusion pathway switch and the drainage pathway switch, and open or close the corresponding pathways at the appropriate time, thereby ensuring the accuracy and timeliness of perfusion and drainage, and avoiding mixing or backflow between the perfusion fluid and the drainage fluid, thereby ensuring the safety of the treatment process.

[0009] In a preferred example, the present application may be further configured as follows: the interactive control unit includes an input module, a processing controller and a display module; The input module is used to receive preset parameters input by a user and send the preset parameters to the processing controller, wherein the preset parameters include a preset intracranial pressure range and a preset drainage volume range; The processing controller is used to receive an intracranial pressure parameter and a drainage volume parameter, and dynamically determine a current perfusion and drainage mode according to the intracranial pressure parameter, the drainage volume parameter, the preset intracranial pressure range, and the preset drainage volume range; The display module is used to display the intracranial pressure parameters and drainage volume parameters received by the processing controller.

[0010] By adopting the above technical solution, the input module allows the user to input preset parameters, such as a preset intracranial pressure range and a preset drainage volume range, so that medical staff can flexibly set them according to the patient's specific situation and treatment needs, making the treatment process more personalized. The processing controller dynamically determines the most suitable perfusion and drainage mode at the moment, and can accurately control the treatment process to avoid excessive or insufficient perfusion and drainage. The display module displays the intracranial pressure parameters and drainage volume parameters received by the processing controller in real time, providing clear visual feedback for doctors or operators, helping medical staff to grasp the patient's treatment situation at any time, and promptly discover and deal with any abnormal situation.

[0011] In a preferred example, the present application can be further configured as follows: the processing controller is used to determine the current perfusion and drainage mode as the normal perfusion and drainage mode when the intracranial pressure parameter is within the preset intracranial pressure range and the drainage volume parameter is within the preset drainage volume range; when the intracranial pressure parameter is within the preset intracranial pressure range and the drainage volume parameter is lower than the lower limit of the preset drainage volume range, the current perfusion and drainage mode is determined as the dredging mode; when the intracranial pressure parameter is higher than the upper limit of the preset intracranial pressure range and the drainage volume parameter is within the preset drainage volume range, the current perfusion and drainage mode is determined as the drainage mode.

[0012] By adopting the above technical solution, the intracranial pressure parameters are compared with the preset intracranial pressure range, and the drainage volume is compared with the preset drainage volume range. The current perfusion and drainage mode is determined according to the comparison results, thereby avoiding the risk of treatment delays caused by manual observation and judgment, realizing automatic perfusion and drainage control, reducing the probability of manual perfusion and flushing, and reducing the possibility of infection or catheter replacement surgery.

[0013] In a preferred example, the present application can be further configured as follows: the processing controller is also used to send an alarm signal when it is monitored that the intracranial pressure parameter is higher than the upper limit of the preset intracranial pressure range and the drainage volume parameter is lower than the lower limit of the preset drainage volume range.

[0014] By adopting the above technical solution, when the intracranial pressure is too high and tube blockage occurs, an alarm signal is issued, which can avoid further deterioration of the disease and improve the treatment effect.

[0015] In a preferred example, the present application can be further configured as follows: when the current perfusion and drainage mode is the dredging mode, The control instructions corresponding to the dredging mode are used to control the perfusion unit and the drainage unit to perform enhanced perfusion and drainage operations alternately according to a preset rhythm; Among them, the enhanced perfusion and drainage operation is performed alternately according to a preset rhythm, including: after the perfusion pathway switch is opened and the drainage pathway switch is closed for continuous perfusion for a first preset time period, the perfusion pathway switch is closed and the drainage pathway switch is opened to drain the fluid in the patient's ventricle into the drainage bag and continue drainage for a second preset time period, and the operations are performed alternately in sequence.

[0016] By adopting the above technical solution, the pressure difference between the patient's ventricle and the drainage tube is increased through the dredging mode, and the blocked drainage tube channel is dredged through continuous perfusion and drainage.

[0017] In a preferred example, the present application can be further configured as follows: the interactive control unit is also used to control the drainage bag lifting device connected to the drainage bag to descend to a preset height when the current perfusion drainage mode is the dredging mode, and to control the drainage bag lifting device to rise to the preset height when exiting the dredging mode.

[0018] By adopting the above technical solution and adjusting the height of the drainage bag, the pressure difference between the patient's ventricle and the drainage tube can be further increased in the dredging mode, thereby improving the dredging effect.

[0019] In a preferred example, the present application can be further configured as follows: when the current perfusion and drainage mode is the drainage mode, The control instruction corresponding to the drainage mode is used to control the closing of the perfusion path switch and the opening of the drainage path switch.

[0020] By adopting the above technical solution, the drainage mode does not perform perfusion and only drains the fluid in the patient's ventricles through the opened drainage passage switch, which can quickly reduce the patient's ventricular pressure and restore the intracranial pressure to normal levels.

[0021] In a preferred example, the present application may be further configured as follows: when the current perfusion and drainage mode is the normal perfusion and drainage mode, The control instructions corresponding to the normal perfusion and drainage mode are used to control the perfusion unit to perfuse with the perfusion volume set by the user when the intracranial pressure parameter is lower than the upper limit of the preset intracranial pressure range, and to control the drainage unit to drain with the drainage volume set by the user when the intracranial pressure parameter is higher than the lower limit of the preset intracranial pressure range.

[0022] By adopting the above technical solution, the perfusion unit and the drainage unit perform a normal perfusion and drainage mode, ensuring that the fluid in the patient's ventricles can be diluted and discharged normally, which can effectively reduce the possibility of tube blockage and ensure a stable drainage effect.

The embodiments also need to be implemented with the authorization and consent of the object.

[0034] The present application embodiment provides a perfusion drainage system, such as Figure 1 As shown, the system includes: a perfusion unit, a drainage unit, an interactive control unit and a drainage tube.

[0035] For details, see Figure 2 , an interactive control unit is used to obtain intracranial pressure parameters and drainage volume parameters of the patient's ventricles, dynamically determine the current perfusion and drainage mode according to the intracranial pressure parameters and drainage volume parameters, and generate control instructions corresponding to the current perfusion and drainage mode. The current perfusion and drainage mode is one of the following modes: normal perfusion and drainage mode, unblocking mode, and drainage mode. Among them, the unblocking mode is used to remove the blockage of the drainage tube.

[0036] A drainage tube is used to connect the perfusion unit and the drainage unit to the patient's ventricle, respectively. The drainage tube can be a double-lumen drainage tube or a multi-lumen drainage tube, comprising at least two channels, one end of the first channel is connected to the perfusion unit, and the other end is connected to the patient's ventricle, and is used to inject the liquid of the perfusion unit into the patient's ventricle through the first channel and the drainage hole; one end of the second channel is connected to the patient's ventricle, and the other end is connected to the drainage unit, and the drainage unit is used to drain the liquid in the patient's ventricle into the drainage bag of the drainage unit through the drainage hole and the second channel.

[0037] The perfusion unit and the drainage unit are used to receive control instructions sent by the interactive control unit and perform perfusion and / or drainage on the patient's ventricles according to the control instructions.

[0038] Among them, the perfusion unit includes a perfusion liquid bag, a peristaltic pump, a perfusion pathway switch, an intracranial pressure sensor and an ultrasonic bubble sensor. The perfusion pathway switch is connected to the patient's ventricle through the drainage tube, and is used to control whether the perfusion unit is working. The intracranial pressure sensor is placed on the perfusion pipeline. The height of the intracranial pressure sensor can be fixed to be consistent with the ventricle, and is not limited by the position of the traditional intracranial pressure sensor on the three-way valve at the drainage bag. It is used to obtain intracranial pressure parameters and send them to the interactive control unit. The peristaltic pump is used to inject the liquid in the perfusion liquid bag into the patient's ventricle when the perfusion pathway switch is turned on, thereby completing the perfusion. The peristaltic pump can also monitor the injection volume parameter injected into the patient's ventricle and send it to the interactive air unit. The injection volume parameter represents the amount of liquid injected into the patient's ventricle by the peristaltic pump per unit time. The ultrasonic bubble sensor is used to monitor whether there are bubbles entering the patient's ventricle through the perfusion pipeline.

[0039] The drainage unit includes a drainage passage switch, a liquid flow meter and a drainage bag. The liquid flow meter obtains the flow parameters of the drainage unit draining out of the patient's ventricle per unit time and sends them to the interactive control unit. The drainage passage switch is used to control whether the drainage unit is working. When the drainage passage switch is turned on, the liquid in the patient's ventricle flows into the drainage bag through the drainage tube, thereby achieving drainage.

[0040] The interactive control unit includes a display module, an input module and a processing controller. The input module includes an interactive interface for medical staff to input preset parameters and send them to the processing controller. The processing controller, as a processor, is used to receive the monitoring results of ultrasonic bubbles, the injection volume parameters sent by the peristaltic pump, and the flow parameters sent by the liquid flow meter, and calculate the difference between the flow parameter and the injection volume parameter, that is, the amount of fluid drained out of the patient's ventricle per unit time, that is, the drainage volume parameter.

[0041] In the embodiments of the present application, different patients and conditions may require different perfusion and drainage strategies. The interactive control unit automatically and dynamically determines the current perfusion and drainage mode according to the intracranial pressure parameters and the drainage volume parameters, generates corresponding control instructions, realizes personalized treatment, and improves the treatment effect. The perfusion unit and drainage unit connected to the patient's ventricle through the drainage tube perform perfusion and / or drainage according to the control instructions, which reduces human intervention, simplifies the perfusion and drainage control process, and improves the treatment efficiency.

[0042] In a possible implementation of the embodiment of the present application, the interaction control unit includes an input module, a processing controller and a display module; An input module, used to receive preset parameters input by a user and send the preset parameters to a processing controller, wherein the preset parameters include a preset intracranial pressure range and a preset drainage volume range; A processing controller, used for receiving an intracranial pressure parameter and a drainage volume parameter, and dynamically determining a current perfusion and drainage mode according to the intracranial pressure parameter, the drainage volume parameter, a preset intracranial pressure range, and a preset drainage volume range; The display module is used to display the intracranial pressure parameters and drainage volume parameters received by the processing controller.

[0043] In this embodiment, the medical staff sets and inputs preset parameters to the input module based on clinical experience and medical knowledge. The preset parameters may include a preset intracranial pressure monitoring frequency, a preset intracranial pressure range, and a preset drainage volume range. The input module sends the preset parameters to the processing controller. The preset intracranial pressure range represents a normal range of intracranial pressure, and the preset drainage volume range represents a normal range of drainage volume.

[0044] After receiving the preset intracranial pressure monitoring frequency, the processing controller generates a corresponding monitoring signal and sends it to the intracranial pressure sensor, so that the intracranial pressure sensor monitors according to the preset intracranial pressure monitoring frequency and sends the obtained intracranial pressure parameters to the processing controller.

[0045] The display module can also be used to display the current perfusion and drainage mode.

[0046] In the embodiment of the present application, the input module allows the user to input preset parameters, such as a preset intracranial pressure range and a preset drainage volume range, so that medical staff can flexibly set them according to the patient's specific situation and treatment needs, making the treatment process more personalized. The processing controller dynamically determines the most suitable perfusion and drainage mode at the moment, and can accurately control the treatment process to avoid excessive or insufficient perfusion and drainage. The display module displays the intracranial pressure parameters and drainage volume parameters received by the processing controller in real time, providing clear visual feedback for doctors or operators, helping medical staff to grasp the patient's treatment situation at any time, and promptly discover and deal with any abnormal situation.

[0047] A possible implementation method of an embodiment of the present application is that the processing controller is used to determine the current perfusion and drainage mode as the normal perfusion and drainage mode when the intracranial pressure parameter is within a preset intracranial pressure range and the drainage volume parameter is within a preset drainage volume range; when the intracranial pressure parameter is within the preset intracranial pressure range and the drainage volume parameter is lower than the lower limit of the preset drainage volume range, the current perfusion and drainage mode is determined as the dredging mode; when the intracranial pressure parameter is higher than the upper limit of the preset intracranial pressure range and the drainage volume parameter is within the preset drainage volume range, the current perfusion and drainage mode is determined as the drainage mode.

[0048] In this embodiment, the processing controller compares the received intracranial pressure parameter with the preset intracranial pressure range, and compares the received drainage volume parameter with the preset drainage volume range, so as to determine the current perfusion and drainage mode.

[0049] In addition, when the intracranial pressure parameter is lower than the lower limit of the preset intracranial pressure range, the processing controller determines the current perfusion and drainage mode as the monitoring mode. The perfusion unit also includes a perfusion pathway switch for turning on / off the perfusion unit, and the drainage unit also includes a drainage pathway switch for turning on / off the drainage unit. The control instructions corresponding to the monitoring mode are used to control the perfusion pathway switch and the drainage pathway switch to be closed, and the perfusion unit and the drainage unit do not work, and only continuous intracranial pressure monitoring is performed.

[0050] The embodiment of the present application compares the intracranial pressure parameters with the preset intracranial pressure range, compares the drainage volume with the preset drainage volume range, and determines the current perfusion and drainage mode according to the comparison results, thereby avoiding the risk of treatment delays caused by manual observation and judgment, realizing automatic perfusion and drainage control, reducing the probability of requiring manual perfusion and flushing, and reducing the possibility of infection or catheter replacement surgery.

[0051] In a possible implementation of the embodiment of the present application, the processing controller is also used to send an alarm signal when it is monitored that the intracranial pressure parameter is higher than the upper limit of a preset intracranial pressure range and the drainage volume parameter is lower than the lower limit of a preset drainage volume range.

[0052] In this embodiment, when the intracranial pressure parameter is higher than the preset upper limit of the intracranial pressure range and the drainage volume is lower than the preset lower limit of the drainage volume range, it can be determined that the tube is blocked, and the intracranial pressure is too high, perfusion is not allowed, and the blockage cannot be removed through the dredging mode, and manual intervention is required. The lower limit of the above-mentioned drainage volume range is determined based on the conventional drainage volume and the abnormal ratio. For example, the lower limit of the drainage volume range is determined based on the conventional drainage volume and the abnormal ratio of 20%. The conventional drainage volume can be obtained based on the previously stable drainage flow data statistics, and the abnormal ratio can be set according to actual needs. This embodiment does not make specific limitations. The above-mentioned special tube blockage situation cannot automatically remove the tube blockage, and an audible and visual alarm signal can be issued to remind medical staff to intervene, such as manually controlling the peristaltic pump to pump in liquid, or replacing the drainage tube.

[0053] The embodiment of the present application sends out an alarm signal when the intracranial pressure is too high and tube blockage occurs, which can prevent the condition from further deteriorating and improve the treatment effect.

[0054] In a possible implementation of the embodiment of the present application, the perfusion unit includes a perfusion passage switch and a perfusion liquid bag, and the drainage unit includes a drainage passage switch and a drainage bag; A perfusion fluid bag, used for perfusing fluid into the patient's cerebral ventricle when the perfusion passage is open; The drainage bag is used to drain the fluid in the patient's ventricles when the drainage passage switch is open.

[0055] When the perfusion passage is open, the peristaltic pump of the perfusion unit injects the liquid in the perfusion liquid bag into the patient's ventricles to dilute the accumulated fluid; when the drainage passage switch is open, the drainage unit drains the diluted liquid out of the patient's ventricles.

[0056] In the embodiment of the present application, the perfusion unit and the drainage unit respectively realize precise control of the perfusion and drainage processes through the perfusion pathway switch and the drainage pathway switch, and open or close the corresponding pathways at the appropriate time, thereby ensuring the accuracy and timeliness of perfusion and drainage, and avoiding mixing or backflow between the perfusion fluid and the drainage fluid, thereby ensuring the safety of the treatment process.

[0057] In a possible implementation of the embodiment of the present application, when the current perfusion and drainage mode is the dredging mode, The control instructions corresponding to the dredging mode are used to control the perfusion unit and the drainage unit to perform enhanced perfusion and drainage operations alternately according to a preset rhythm; Among them, alternatingly performing enhanced perfusion and drainage operations according to a preset rhythm includes: after the perfusion pathway switch is opened and the drainage pathway switch is closed for continuous perfusion for a first preset time period, the perfusion pathway switch is closed and the drainage pathway switch is opened to drain the fluid in the patient's ventricles into the drainage bag and continue drainage for a second preset time period, and the operations are performed alternately in sequence.

[0058] In this embodiment, the perfusion pathway switch is turned on and the drainage pathway switch is closed, and liquid is pumped into the perfusion pathway by a peristaltic pump to increase the pressure in the perfusion pathway. The obstruction at the drainage hole is flushed out of the hole first by the pressure difference between the perfusion pathway and the patient's ventricle, and the patient's ventricle pressure is appropriately increased. Then the drainage pathway switch is controlled to open and the perfusion switch is closed, and the obstruction near the drainage tube opening is flushed into the drainage tube through the opening by using the greater pressure difference between the patient's ventricle and the drainage tube, thereby unblocking the blocked channel. Repeat the above operation, and to a certain extent use the "water hammer effect" to expand the pressure difference inside and outside the drainage hole to unblock the blocked drainage hole, until the blocked pipeline is unblocked, that is, the intracranial pressure parameter is in the preset intracranial pressure range and the drainage volume parameter is in the preset drainage volume range, and the current unblocking mode is switched to the normal perfusion and drainage mode. Among them, the first preset time length and the second preset time length are affected by factors such as the specifications of the drainage tube and the drainage site, and can be set by medical staff based on clinical experience and medical knowledge. The optimal first preset time length and second preset time length can also be determined by experiments under different conditions. After the medical staff selects specific conditions through the interactive control unit, the appropriate first preset time length and second preset time length are automatically recommended. This embodiment does not make specific limitations.

[0059] The embodiment of the present application expands the pressure difference between the inside and outside of the drainage hole through the dredging mode, thereby more effectively relieving the blockage of the drainage tube.

[0060] In a possible implementation of an embodiment of the present application, the interactive control unit is also used to control the drainage bag lifting device connected to the drainage bag to descend to a preset height when the current perfusion drainage mode is the dredging mode, and to control the drainage bag lifting device to rise to a preset height when exiting the dredging mode.

[0061] In this embodiment, the drainage unit may further include a drainage bag lifter, and the processing controller controls the drainage bag lifter. In normal mode (e.g., normal perfusion drainage mode), the drainage bag is set at a commonly used fixed height, such as a height slightly lower than the ventricle. In the dredging mode, the drainage bag is automatically lowered to a preset height by the drainage bag lifter, which can further increase the pressure difference between the patient's ventricle and the drainage bag, and use the larger pressure difference to dredge the blocked drainage tube channel. After the drainage tube is dredged, that is, the intracranial pressure parameter is within the preset intracranial pressure range and the drainage volume is within the preset drainage volume range, exit the dredging mode and control the drainage bag lifter to raise the drainage bag to the original height. The above preset height can be set according to actual needs, and this embodiment is not limited.

[0062] The embodiment of the present application can further increase the pressure difference between the patient's ventricle and the drainage tube in the dredging mode by adjusting the height of the drainage bag, thereby improving the dredging effect.

[0063] In a possible implementation of the embodiment of the present application, when the current perfusion and drainage mode is the drainage mode, The control instructions corresponding to the drainage mode are used to control the closing of the perfusion path switch and the opening of the drainage path switch.

[0064] In drainage mode, if the intracranial pressure is too high but there is no blockage, the fluid in the patient's ventricles is drained without perfusion through the open drainage pathway switch, which can quickly reduce the patient's ventricular pressure and restore the intracranial pressure to normal levels.

[0065] In a possible implementation of the embodiment of the present application, when the current perfusion and drainage mode is the normal perfusion and drainage mode, The control instructions corresponding to the normal perfusion and drainage mode are used to control the perfusion unit to perfuse at the perfusion volume set by the user when the intracranial pressure parameter is lower than the upper limit of the preset intracranial pressure range, and to control the drainage unit to drain at the drainage volume set by the user when the intracranial pressure parameter is higher than the lower limit of the preset intracranial pressure range.

[0066] The perfusion unit and the drainage unit work independently. The preset parameters set by the user through the input module also include perfusion volume and drainage volume. The processing controller controls the perfusion unit and the drainage unit to perform a normal perfusion and drainage mode according to the received perfusion volume and drainage volume.

[0067] Among them, the perfusion unit works when the intracranial pressure parameter is lower than the preset upper limit of the intracranial pressure range, and the processing controller sends an instruction to control the perfusion pathway switch to open. The liquid in the perfusion fluid bag passes through the peristaltic pump and the perfusion pathway switch in turn, and flows into the patient's ventricle to complete the perfusion; the drainage unit works when the intracranial pressure parameter is higher than the preset lower limit of the intracranial pressure range, and the processing controller sends an instruction to control the drainage pathway switch to open to drain the patient's ventricular fluid.

[0068] In the embodiment of the present application, the perfusion unit and the drainage unit perform a normal perfusion and drainage mode, ensuring that the fluid in the patient's ventricles can be diluted and discharged normally, which can effectively reduce the possibility of tube blockage and ensure a stable drainage effect.

[0069] The present application embodiment provides a perfusion drainage control method, such as Figure 3 As shown, the method provided in the embodiment of the present application is performed by an electronic device, which can be a server or a terminal device, wherein the server can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services.

The dredging mode is used to remove the blockage of the drainage tube.
