Description

Technical Field

[0001] The present invention relates to the technical field of thrombus monitoring, and in particular to a central venous thrombus monitoring system and a clearing device. Background Art

[0002] The central venous thrombosis monitoring system is a medical device specifically used to monitor the risk of central venous thrombosis in patients. By collecting and analyzing the patient's physiological data, medical history information and imaging data, the system can assess the patient's thrombosis risk in real time and provide early warning information, thereby helping doctors take preventive measures in a timely manner and reduce the incidence of thrombotic events.

[0003] However, the monitoring system in the prior art has the following problems. It mainly determines whether there is a possibility of thrombosis through blood concentration and blood flow rate, and both are approximate values. When the patient is a thrombosis patient, different physical conditions cause the values ​​at the time of monitoring to be different from the actual values ​​under normal conditions, resulting in misjudgment or too late diagnosis. Therefore, the present invention provides a central venous thrombosis monitoring system and a removal device. Summary of the invention

[0004] In view of the above existing problems, the present invention is proposed.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0006] A central venous thrombosis monitoring and removal device is composed of four modules: a monitoring module, an early warning module, a data analysis module and an interactive module, wherein the monitoring module includes the following contents:

[0007] By connecting the MEMS sensor to the catheter after puncture and calibrating it, it starts to monitor the patient's central venous pressure, blood flow velocity and blood concentration, and records the data. When recording, it determines whether the warning value has been reached. If it has been reached, the instruction is directly sent to the warning module, and the blood flow data is transmitted to the data analysis module and the interaction module. If it has not been reached, the patient's blood flow data continues to be monitored, and the data information is directly transmitted to the data analysis module after being sorted. When the data analysis module is transmitting, staged data transmission is adopted, that is, the change value is recorded during data transmission, the data fluctuations within the stage are classified, and the proportion of each identical data in the monitoring time is confirmed and marked, which accelerates and facilitates the rapid analysis of subsequent data.

[0008] Furthermore, the early warning module includes the following contents:

[0009] S001. The early warning module has two alarm conditions. In the first case, when the monitoring module collects data and detects that the collected data has reached or exceeded the data of thrombus existence, the monitoring module directly issues a thrombus existence instruction to the early warning module and issues an early warning, and transmits the data to the interactive module at the same time.

[0010] S002. The second method is that the data analysis module issues a warning instruction to control the warning module to issue a warning.

[0011] Furthermore, the data analysis module includes the following contents:

[0012] SS001. After the data analysis module receives the blood flow data information from the monitoring module, it will analyze the received data. During the analysis, all non-identical data will be sorted out. After sorting out, the data with the highest proportion will be marked. After marking, the data will be analyzed by the analysis module. If the result is within the safety value, the analysis module will directly transmit the analyzed data to the interaction module. If the analyzed data is higher than the safety value, the analysis module will transmit the analyzed data to the interaction module and the early warning module at the same time, and issue an early warning through the early warning module.

[0013] SS002. When analyzing blood flow data that is within the critical range of safety values, the data will be transmitted to the early warning system and marked as a secondary warning, that is, a critical warning, and transmitted to the interactive module at the same time.

[0014] Furthermore, the interaction module includes the following contents:

[0015] SSS001. First, when the information of the interactive module is transmitted by the monitoring module, it indicates that the patient has thrombus. The blood flow parameters are directly converted into a graphical display, which shows the blood flow velocity and pressure distribution diagram. At the same time, the treatment plan for the recovery of patients with the same thrombus with the same or similar blood flow data in the medical database will be displayed to facilitate the medical staff to make auxiliary choices after combination. Then the interactive module will prompt that the elimination device needs to be used to eliminate the thrombus;

[0016] SSS002. When the data of the interactive module is transmitted by the data analysis module, it means that it is within the safe value. At this time, the data in the data analysis module will be displayed interactively. When displaying, the heavier areas will be marked, which means that the data is at the normal value. If the normal value is at the critical safety value, the possibility of thrombosis can be intuitively seen from the graph, which is convenient for prevention.

[0017] A device for monitoring and removing central venous thrombosis comprises a catheter, wherein the inner wall of the catheter is movably sleeved with a blocking tube, the outer wall of the end of the blocking tube away from the outer wall is fixedly connected to one end of a first soft outer expansion bag, the other end of the first soft outer expansion bag is fixedly connected to a first supporting wire mesh, the other end of the first soft outer expansion bag is fixedly connected to an end located close to the blocking tube, the inner wall of the blocking tube is movably sleeved with a thrombus retention tube, the inner wall of the thrombus retention tube is movably sleeved with a puncture tube, the puncture tube The end of the tube located away from the catheter is fixedly connected to a puncture head, the end of the thrombus indwelling tube located close to the puncture head is fixedly connected to a large support net, the end of the large support net located away from the thrombus indwelling tube is fixedly connected to a connecting tube, the end of the connecting tube located away from the large support net is fixedly connected to a second support net, the end of the second support net located away from the connecting tube is fixedly connected to a second soft outer expansion balloon, and the end of the second soft outer expansion balloon located away from the second support net is movably connected to the end of the puncture head close to the second soft outer expansion balloon.

[0018] Furthermore, the first supporting wire mesh, the large supporting mesh and the second supporting mesh are all made of the same soft metal wire, and the second soft outer expansion bag and the first soft outer expansion bag are all made of the same soft rubber material.

[0019] Furthermore, the second soft outer expansion bag and the first soft outer expansion bag will be propped up by the second propping up net and the first propping up wire mesh respectively when working, and the first propping up wire mesh, the large propping up net and the second propping up net will also be propped up when working.

[0020] In the above technical solution, the technical effects and advantages provided by the present invention are:

[0021] 1. The early warning module in the present invention can respond quickly to monitoring data. When the early warning value is reached or exceeded, an alarm is immediately issued to remind medical staff to take timely intervention measures.

[0022] 2. The data analysis module of the present invention adopts staged data transmission and analysis, which can accurately capture the changing trend of blood flow data, mark and classify abnormal data, and at the same time, by comparing and analyzing historical data, it can identify the risk factors of thrombosis and provide a basis for formulating personalized treatment plans.

[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0033] The embodiment of the present invention discloses a central venous thrombosis monitoring and removal device, which includes four modules: a monitoring module, an early warning module, a data analysis module, and an interactive module. The monitoring module includes the following contents:

[0034] By connecting the MEMS sensor to the catheter after puncture and calibrating it, it starts to monitor the patient's central venous pressure, blood flow velocity and blood concentration, and records the data. When recording, it determines whether the warning value has been reached. If it has been reached, the instruction is directly sent to the warning module, and the blood flow data is transmitted to the data analysis module and the interaction module. If it has not been reached, the patient's blood flow data continues to be monitored, and the data information is directly transmitted to the data analysis module after being sorted. When the data analysis module is transmitting, staged data transmission is adopted, that is, the change value is recorded during data transmission, the data fluctuations within the stage are classified, and the proportion of each identical data in the monitoring time is confirmed and marked, which accelerates and facilitates the rapid analysis of subsequent data.

[0035] Furthermore, the early warning module includes the following contents:

[0036] S001. The early warning module has two alarm conditions. In the first case, when the monitoring module collects data and detects that the collected data has reached or exceeded the data of thrombus existence, the monitoring module directly issues a thrombus existence instruction to the early warning module and issues an early warning, and transmits the data to the interactive module at the same time.

[0037] S002. The second method is that the data analysis module issues a warning instruction to control the warning module to issue a warning.

[0038] Furthermore, the data analysis module includes the following contents:

[0039] SS001. When the data analysis module receives the blood flow data information from the monitoring module, it will analyze the received data. During the analysis, all non-identical data will be sorted out. After sorting out, the data with the highest proportion will be marked. After marking, the data will be analyzed by the analysis module. If the result is within the safety value during the analysis, the analysis module will directly transmit the analyzed data to the interaction module. If the analyzed data is higher than the safety value, the analysis module will transmit the analyzed data to the early warning module at the same time as the interaction module and issue an early warning through the early warning module. For example, in actual monitoring, if there are ups and downs in blood flow data, the blood flow data that has been maintained for the longest time will be used as the proportion according to the state, and multiple multi-segment measurements will be performed to ensure that the monitoring data is prevented from being abnormal due to errors.

[0040] SS002. When analyzing blood flow data that is within the critical range of safety values, the data will be transmitted to the early warning system and marked as a secondary warning, that is, a critical warning, and transmitted to the interactive module at the same time.

[0041] Furthermore, the interaction module includes the following contents:

[0042] SSS001. First, when the information of the interactive module is transmitted by the monitoring module, it indicates that the patient has thrombus. The blood flow parameters are directly converted into a graphical display, which shows the blood flow velocity and pressure distribution diagram. At the same time, the treatment plan for the recovery of patients with the same thrombus with the same or similar blood flow data in the medical database will be displayed to facilitate the medical staff to make auxiliary choices after combination. Then the interactive module will prompt that the elimination device needs to be used to eliminate the thrombus;

[0043] SSS002. When the data of the interactive module is transmitted by the data analysis module, it means that it is within the safety value. At this time, the data in the data analysis module will be interactively displayed. When displaying, the heavier area will be marked, which means that the data is at the normal value. If the normal value is at the critical safety value, the possibility of thrombosis can be intuitively seen from the graph, which is convenient for prevention. That is, the safety value is Q, Q < 1, 1 means thrombosis, if Q is less than 1, it is a safety value, and the critical safety value L is a manually controlled quantity. For example, if it is considered that the control above 0.9 is the critical safety value, it will be set as the critical safety value to better alert and prevent the occurrence of thrombosis.

[0044] like Figure 1-5 The central venous thrombosis monitoring and clearing device comprises a catheter 1, wherein the inner wall of the catheter 1 is movably sleeved with 2, wherein the inner wall of the 2 is movably sleeved with a blocking tube 5, wherein the outer wall of the end of the blocking tube 5 away from 2 is fixedly connected with one end of a first soft external expansion bag 4, wherein the other end of the first soft external expansion bag 4 is fixedly connected with a first supporting wire mesh 3, wherein the other end of the first soft external expansion bag 4 is fixedly connected with the end of 2 located near the blocking tube 5, wherein the inner wall of the blocking tube 5 is movably sleeved with a thrombus retention tube 6, wherein the inner wall of the thrombus retention tube 6 is movably sleeved with a puncture tube 12, wherein the puncture tube 12 A puncture head 11 is fixedly connected to the end away from the catheter 1, a large support net 7 is fixedly connected to the end of the thrombus indwelling tube 6 close to the puncture head 11, a connecting tube 8 is fixedly connected to the end of the large support net 7 away from the thrombus indwelling tube 6, a second support net 9 is fixedly connected to the end of the connecting tube 8 away from the large support net 7, a second soft outer expansion balloon 10 is fixedly connected to the end of the second support net 9 away from the connecting tube 8, and the second soft outer expansion balloon 10 is movably connected to the end of the puncture head 11 close to the second soft outer expansion balloon 10 at the end away from the second support net 9.

[0045] Furthermore, the first supporting wire mesh 3, the large supporting mesh 7 and the second supporting mesh 9 are all made of the same soft metal wire, and the second soft outer expansion bag 10 and the first soft outer expansion bag 4 are all made of the same soft rubber material.

[0046] Furthermore, the second soft outer expansion bag 10 and the first soft outer expansion bag 4 will be propped up by the second support net 9 and the first support wire mesh 3 respectively when working, and the first support wire mesh 3, the large support net 7 and the second support net 9 will also be propped up when working.

[0047] Working principle of the present invention:

[0048] When working, the device is first connected to the catheter 1. After the thrombus position is determined, the puncture tube 12, the thrombus retention tube 6, the blocking tube 5 and 2 start to work. 2 first blocks the blood vessel position close to the thrombus and the catheter 1. At this time, 2 is extended, and the blocking tube 5 stops extending, causing the first propping up wire mesh 3 to expand the first soft outer expansion balloon 4 to form a nearly round cake-shaped blocking block. At this time, the puncture tube 12 continues to extend, and after passing through the thrombus for a distance, the thrombus retention tube 6 is continued to be pushed, so that the second soft outer expansion balloon 10 is propped up after it abuts the puncture head 11, thereby blocking the other end of the thrombus. At this time, the thrombus retention tube 6 and the puncture tube 12 are pulled toward the position of the catheter 1, thereby After the thrombus is pulled to the position of the catheter 1, the pull 2 ​​lowers the first support mesh 3 and the first soft outer expansion balloon 4. As the operation continues, the thrombus located at the thrombus retention tube 6 is pulled into the catheter 1. As the pulling continues, the outer wall of the large support mesh 7 is compressed, but the thrombus is still blocked. After continuing to pull, when the second support mesh 9 reaches the catheter 1, the thrombus retention tube 6 is slowly pulled back, so that the second soft outer expansion balloon 10 does not block the catheter 1, forming multiple large support meshes 7 and the filter screen of the second support mesh 9 and the second soft outer expansion balloon 10. The gap between the inner wall of the catheter 1 is small, which makes it impossible for large particles of thrombus fragments to flow, thereby completely clearing the thrombus at this location, and at the same time, blood will flow out from the gap, thereby achieving the purpose of only clearing the thrombus but not the blood.

[0049] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
