Description

Technical Field

[0001] The present application relates to the field of medical devices, and in particular to a system and method for preventing coagulation of autologous blood used for staining in thoracic and pulmonary lymphadenectomy. Background Art

[0002] Tumor cells can metastasize to different organs and tissues through the blood or lymph. Therefore, clearing the lymph nodes of specific organs or tissues is the key to treatment. During the clearance process, it is crucial to completely remove all diseased lymph nodes. During surgery, it is not easy to identify all lymph nodes in a region. Thoracic lymph node dissection is an important part of the treatment of lung cancer. Taking hilar lymph node dissection as an example, the thoracic lymph node dissection currently required for lung cancer patients includes N1 group lymph nodes (peritracheal lymph nodes, paratracheal lymph nodes, pericarinal lymph nodes, lymph nodes around the upper, middle and lower pulmonary veins, posterior left atrium lymph nodes, and lymph nodes around the descending aorta) and N2 lymph nodes (regional lymph nodes). The pathological conditions of lung cancer patients vary greatly. Even for the same patient, the size and shape of the tumor will change over time. Therefore, it is necessary to determine the number and metastasis status of regional lymph nodes at a certain time through staining multiple times. The thoroughness of lymph node staining and removal is of great significance to the patient's prognosis. Inadequate staining may result in the inability to identify the stained lymph nodes, while excessive staining may cause unnecessary harm to the patient or even endanger his life.

[0003] During thoracic and pulmonary lymph node dissection, doctors will identify the site of lymph node staining, which generally requires the collection of peripheral blood or the use of autologous induced blood. However, peripheral blood collection is troublesome and will result in a large loss of blood.

[0004] At present, autologous blood often uses coagulation time as a measure of whether it is suitable for staining blood. Since capacitance has a good positive correlation with blood coagulation, coagulation time can often be characterized by measuring capacitance. However, multiple staining is required in lymph node dissection. During the staining process, sometimes the doctor needs to rest or perform some other operations. Sometimes blood coagulation occurs beyond the doctor's expectations, and even abnormal coagulation occurs when the doctor does not check in time. Therefore, a device that can judge whether autologous blood staining is abnormal in real time is needed. Further, blood coagulation is affected by temperature and activation (activation: the process of activating blood fibrinogen into fibrin), especially low-temperature storage of blood can cause delayed coagulation or even abnormality. On the other hand, blood activation takes a certain amount of time. Therefore, the activation time in clinical practice is also an uncertain factor. It takes a certain logical judgment from collecting autologous blood and putting it in a container to starting staining. At present, there is no device on the market that can monitor autologous blood coagulation in real time. Summary of the invention

[0005] The purpose of the present application is to propose a coagulation warning system and method for autologous blood used for staining in thoracic and pulmonary lymphadenectomy, which uses the red blood cell capacitance in the autologous blood as a warning indicator. By measuring the capacitance and the capacitance change trend over time, the coagulation process can be simply and accurately monitored; the system uses an autologous blood collection cup to collect the autologous blood sample and send it to the monitoring cup. The monitoring cup measures the capacitance of the autologous blood sample in the monitoring cup through the capacitance signal acquisition module 4. The central control module analyzes the risk based on the measured capacitance value. If it is within the predetermined risk range, the display module displays a benign result and / or the alarm issues a benign alarm. Otherwise, the alarm prompts that the risk is abnormal, which is conducive to discovering coagulation abnormalities and taking timely measures.

When the capacitance collected by the monitoring capacitor 32 exceeds the preset maximum value, the alarm module 1 alarms.

[0062] Figure 4 The present invention is a flow chart of a method for warning coagulation of autologous blood for staining used in thoracic and pulmonary lymph node dissection.

[0063] The present invention provides a coagulation warning method for autologous blood used for staining in thoracic and pulmonary lymph node dissection, which comprises: S01, starting the system; S02, controlling the puncture needle 11 to puncture the first blood collection pad 13, and the autologous blood sample then flows into the autologous blood collection cup; S03, opening the liquid outlet 14, and controlling the puncture needle 11 to puncture the second blood collection pad 21, and the autologous blood sample flows into the bottom of the monitoring cup; S04, while S02 and S03 are being performed, measuring the capacitance of the autologous blood sample that changes with time through a capacitor; S05, the central control module analyzes the coagulation risk of the autologous blood sample according to the measurement result of S04, and if it is within a predetermined risk range, a benign result is displayed through the display module and / or a benign alarm is issued through the alarm, otherwise it indicates that the risk is abnormal.

[0064] Preferably, after the collection starts, the first blood collection pad is placed close to the patient's body part to collect blood, so that the blood collection pad is filled. If the first blood collection pad 13 overflows when the needle 11 is inserted, the monitoring cup has started to measure the autologous plasma capacitance. The autologous plasma capacity in the monitoring cup 2 is not enough to cover the bottom of the monitoring cup 2. At this time, the autologous plasma capacitance cannot be effectively measured, so re-collection is required.

[0065] Preferably, the capacitance between two electrodes in a capacitor is measured; the autologous plasma capacitance C is related to the concentration of red blood cells, and an increase in the red blood cell concentration C0 will result in an increase in the capacitance C.

[0066] Preferably, measuring the capacitance in the plasma of the autologous blood collection cup 1 comprises the following steps:

[0067] (1) injecting an equal amount of autologous plasma into the autologous blood collection cup 1, and measuring the capacitance value C0 of the liquid storage chamber;

[0068] (2) Measure the capacitance change △C of monitoring cup 2 and calculate the plasma capacitance C1;

[0069] Monitoring cup 2 capacitance change ΔC = C-C0

[0070] Plasma capacitance C1 = 2εεrS / C0 = 8103ΔC

[0071] (3) Monitor the capacitance change value △C of cup 2 and calculate the red blood cell capacitance C1 in the plasma. The red blood cell capacitance C1 in the plasma = C-C1;

[0072] Preferably, the blood collecting pad in this embodiment is made of a flexible material, preferably a capillary porous material.

[0073] Exemplarily, the capillary porous material is a polymer material or a natural polymer material.

[0074] The autologous blood is sampled and the capacitance is monitored in the autologous blood collection cup 1 and the monitoring cup 2. The capacitance measurement in the monitoring cup 2 is measured by the electric signal acquisition module 4 located in the monitoring cup 2. The electric signal acquisition module 4 in the monitoring cup 2 is connected to the electric signal acquisition module through a wire. The electric signal acquisition module 4 in the monitoring cup 2 is connected to the electric signal acquisition module through a wire. The measurement process of the electric signal acquisition module 4 in the monitoring cup 2 is performed at a certain rate, and the measurement rate is preferably 1 to 10 times per second. The alarm level of the present invention is set to different stages after the coagulation of red blood cells, such as red blood cells in a free state, reticular structure formation, red blood cell aggregation, and cell membrane disintegration. The central control module analyzes the current risk level according to the current capacitance value. If the current risk level is benign (for example, red blood cells are in a free state), the warning on the display module 6 is green; if the current risk level is not benign (for example, red blood cells are aggregated), an alarm is issued on the alarm, and the warning on the display module 6 is red. Among them, when the capacitance exceeds the predetermined range, the system prompts that the risk is abnormal and triggers an alarm.

[0075] The film capacitor in this embodiment is a film capacitor. A film capacitor is a capacitor made of a film material, in which two conductive materials are separated by a diaphragm to form a capacitor. The film capacitor has a film insulating medium. The preparation material of the non-conductive biofilm is porous polyimide. The non-conductive biofilm is a biofilm with tiny pores and a charge. The non-conductive biofilm contains a charged salt component. The non-conductive biofilm is prepared from a porous polyimide film containing a salt component. The film capacitor transmits the electrical signal to the electrical signal acquisition module.

[0076] The present invention adopts the above technical solution. The autologous blood coagulation warning system and method for staining of thoracic and pulmonary lymph node dissection of the present invention include an autologous blood collection cup 1, a monitoring cup 2, a capacitor 3, an electrical signal acquisition module 4, a central control module 5, a display module 6 and an alarm 7. The autologous blood collection cup 1 collects the autologous blood sample and sends it to the monitoring cup 2. The electrical signal acquisition module 4 measures the capacitance of the autologous blood sample in the monitoring cup 2. The central control module 5 analyzes its risk according to the measured capacitance value. If it is within the predetermined risk range, the display module 6 displays a benign result and / or the alarm 7 issues a benign alarm, otherwise it indicates that the risk is abnormal. The autologous blood coagulation warning system and method for staining of thoracic and pulmonary lymph node dissection of the present invention uses the red blood cell capacitance in the autologous blood as a warning indicator. By measuring the capacitance and the change trend of the capacitance over time, the coagulation process can be simply and accurately monitored. The autologous blood coagulation warning system and method for staining in thoracic and pulmonary lymph node dissection of the present invention measures the red blood cell state and plasma state in the autologous blood and the change trend of the capacitance with time through capacitance, thereby avoiding the technical problem that blood coagulation in thoracic and pulmonary lymph node dissection causes the inability of the staining solution to stain tumor cells.
