[0023] Please also read Figure 1 and Figure 2 In one embodiment of the present application, a method for recording blood sampling time is provided, which is used to record the blood sampling time of a blood sampling device 100. The blood sampling device 100 includes a blood sampling device 110, a blood sampling tube 120 connected to the blood sampling device 110, a light source 130 disposed on one side of the blood sampling tube 120, and a light transmission sensor 140 disposed on the other side of the blood sampling tube 120 and used to receive light emitted by the light source 130.

[0024] Among them, the blood sampling device 110 is used to extract blood from the human body, the blood sampling tube 120 is connected to the blood sampling device 110, and is used to transport the blood extracted by the blood sampling device 110. The light source 130 is arranged on one side of the blood sampling tube 120 and can be used to irradiate light into the blood sampling tube 120. The light transmission sensor 140 is located on the other side of the blood sampling tube 120, and is used to detect the light intensity of the light source 130 passing through the blood vessel.

[0025] Please continue reading Figure 1 and Figure 2 Specifically, the method for recording the blood sampling time includes:

[0026] S200: Obtaining the light transmittance collected by the light transmittance sensor 140.

[0027] Specifically, the light transmittance collected by the light transmittance sensor 140 represents the light intensity collected by the light transmittance sensor 140 , that is, the light transmittance collected by the light transmittance sensor 140 can reflect the light intensity emitted by the light source 130 and passing through the blood sampling tube 120 .

[0028] Among them, the time points for obtaining the transmittance collected by the transmittance sensor 140 can be continuous or intermittent, that is, the transmittance collected by the transmittance sensor 140 can be obtained in real time, or the transmittance collected by the transmittance sensor 140 can be obtained at preset time intervals, which is not limited here.

[0029] S210: Determine the blood sampling start time point and blood sampling end time point of the blood sampling device 100 according to the light transmittance.

[0030] Specifically, blood itself has a certain degree of light transmittance. When blood flows through the blood collection tube 120, it will change the light propagation path in the blood collection tube 120. Specifically, after blood flows into the blood collection tube 120, blood will absorb part of the light and scatter part of the light, thereby causing the light emitted by the light source 130 to pass through the blood collection tube 120 to decrease, and the amount of light emitted by the light source 130 received by the light transmission sensor 140 will also decrease accordingly. The light transmission sensor 140 can convert the received light into electrical quantity. Therefore, the amount of light received by the light transmission sensor 140 decreases, and its electrical quantity also decreases, that is, the transmittance collected by the light transmission sensor 140 decreases; on the contrary, when all the blood flows out of the blood collection tube 120, the light emitted by the light source 130 to pass through the blood collection tube 120 increases, and the amount of light emitted by the light source 130 received by the light transmission sensor 140 also increases, ultimately causing the transmittance collected by the light transmission sensor 140 to increase. Therefore, the light transmittance collected by the light transmittance sensor 140 can reflect the flow of blood in the blood sampling tube 120. Therefore, according to the change of the light transmittance collected by the light transmittance sensor 140, the start time point and the end time point of blood sampling of the blood sampling device 100 can be determined.

[0031] In the above method, considering that blood will absorb or block light, a light source 130 and a light transmission sensor 140 are set on both sides of the blood sampling tube 120. When blood enters the blood sampling tube 120, the intensity of light passing through the blood sampling tube 120 will become weaker. When the blood in the blood sampling tube 120 flows out, the intensity of light passing through the blood sampling tube 120 will become stronger. Therefore, the flow of blood in the blood sampling tube 120 will cause a change in the transmittance collected by the light transmission sensor 140. Therefore, the present application records the start time and end time of blood sampling of the blood sampling device 100 by sensing the change in transmittance obtained by the light transmission sensor 140, which can realize the automation of blood sampling time recording, and can also improve the accuracy and reliability of blood sampling time recording, and further improve the blood collection efficiency of the blood sampling device 100.

[0032] In one embodiment, a light-transmitting sensor 140 is installed at an appropriate position of the blood collection tube 120 (e.g., a blood collection needle or the outside of the blood collection tube 120) to measure the light intensity passing through the blood or liquid in the blood collection tube 120. The light-transmitting sensor 140 may be a photodiode or a phototransistor, which is sensitive to changes in light intensity and can sensitively detect the degree of light blocking or absorption by the blood passing through the blood collection tube 120. The light-transmitting sensor 140 is a device that can convert light into electricity. Therefore, when the intensity of light becomes weaker after passing through the blood, the amount of light received by the light-transmitting sensor 140 also decreases. Since the light-transmitting sensor 140 converts the received light into electricity, a decrease in the amount of light also means a decrease in electricity. Therefore, the absorbance of blood or liquid can be indirectly measured by measuring the electrical output of the light-transmitting sensor 140. That is, the light intensity of the light emitted by the light source 130 is weakened after passing through the blood or liquid, and the light-transmitting sensor 140 will detect the weakened light after passing through the blood or liquid, so that the amount of light received by the light-transmitting sensor 140 is reduced, and the amount of converted electricity is also reduced, thereby changing the current output of the light-transmitting sensor 140, so that the user can indirectly detect the flow condition of blood or liquid.

[0033] Please continue reading Figure 1 and Figure 2 In one embodiment, step S210 includes:

[0034] S211: In response to the light transmittance decreasing to be less than the first threshold value T1, the current time point is determined as the blood sampling start time point.

[0035] During the blood sampling process, the light transmission sensor 140 will continuously monitor the light intensity passing through the blood sampling tube 120 and calculate the light transmittance accordingly. When blood begins to flow into the blood sampling tube 120, the light transmittance will decrease due to the presence of blood. By setting the first threshold value T1, the first threshold value T1 represents the critical value for the start of blood sampling. When the light transmittance detected by the light transmission sensor 140 decreases to less than T1 for the first time, the system considers that blood sampling has started and records the time point at this time as the start time point of blood sampling.

[0036] S212: In response to the light transmittance increasing to be greater than the second threshold value T2, the current time point is determined as the blood sampling end time point.

[0037] As the blood collection process proceeds, the light transmittance will begin to increase at a certain point in time, indicating that the amount of blood in the blood collection tube 120 is decreasing. A second threshold value T2 is set, and the second threshold value T2 represents the critical value for the end of blood collection. Normally, the second threshold value T2 is greater than the first threshold value T1 to ensure that the blood collection is determined to be over only after the blood completely stops flowing into the blood collection tube 120. When the light transmittance detected by the light transmission sensor 140 increases to greater than T2 for the first time, the system considers that the blood collection is over, and records the time point at this time as the end time point of blood collection.

[0038] Please also read Figure 2 and Figure 3 In one embodiment, the first threshold value T1 is set to 85% and the second threshold value T2 is set to 90%. Before the blood sampling device 110 starts to collect blood, in an ideal state, the light transmittance of the light source 130 passing through the blood sampling tube 120 obtained by the light transmission sensor 140 is 100%, that is, there is no blood or other impurities blocking the light emitted by the light source 130.

[0039] When blood sampling begins, as blood enters the blood sampling tube 120, the transmittance will drop from nearly 100% to below 85%. At this time, the system records the time point when it first drops below 85% as the start time of blood sampling. As the blood sampling process continues, the transmittance remains at a low level. When blood sampling ends, as the amount of blood decreases, the transmittance gradually increases until it exceeds 90%. At this time, the system records the time point when it first exceeds 90% as the end time of blood sampling.

[0040] In other embodiments, the first threshold value T1 and the second threshold value T2 can be adjusted according to actual application conditions to ensure that the start and end times of blood sampling can be accurately captured, which is not limited here.

[0041] Please also read Figure 2 and Figure 4 In another embodiment, step S210 includes:

[0042] S213: In response to the light transmittance decreasing and the decrease in the light transmittance at the current time point compared to the light transmittance at the first initial time point being greater than a third threshold ΔT3, the current time point is determined as the blood sampling start time point, wherein the light transmittance starts to decrease from the first initial time point.

[0043] If the light transmittance monitored at the current time point is smaller than the light transmittance monitored at the previous time point, the current time point is determined as the first initial time point.

[0044] The reduction amplitude refers to the difference between the transmittance at the current time point and the transmittance at the first initial time point. By setting the third threshold ΔT3, the third threshold ΔT3 represents the critical change amplitude for the start of blood sampling. When the transmittance detected by the light transmission sensor 140 decreases and the reduction amplitude is greater than ΔT3, the system considers that blood sampling has started, and records the time point at this time as the start time point of blood sampling.

[0045] S214: In response to the increase in transmittance, and the increase in transmittance at the current time point compared to the transmittance at the second initial time point is greater than a fourth threshold ΔT4, the current time point is determined as the end time point of blood sampling.

[0046] If the light transmittance monitored at the current time point is greater than the light transmittance monitored at the previous time point, the current time point is determined as the second initial time point.

[0047] The increase amplitude refers to the difference between the transmittance at the current time point and the transmittance at the second initial time point. By setting the fourth threshold value ΔT4, the fourth threshold value ΔT4 represents the critical change amplitude for the end of blood sampling. Normally, the fourth threshold value ΔT4 needs to be set according to the actual situation to ensure that the blood sampling is judged to be over only after the blood completely stops flowing into the blood sampling tube 120. When the transmittance detected by the light transmission sensor 140 increases and the increase amplitude is greater than the fourth threshold value ΔT4, the system considers that the blood sampling is over and records the time point at this time as the end time point of blood sampling.

[0048] Please continue reading Figure 2 and Figure 4 In one embodiment, the third threshold ΔT3 is set to 15%, and the fourth threshold ΔT4 is set to 5%. Before the blood sampling device 110 starts to collect blood, in an ideal state, the light transmittance of the light source 130 passing through the blood sampling tube 120 obtained by the light transmission sensor 140 is 100%, that is, there is no blood or other impurities blocking the light emitted by the light source 130.

[0049] When blood starts to flow into the blood collection tube 120, the transmittance begins to decrease. If the transmittance decreases by more than 15% for the first time, for example, from 100% to 85%, the time point at this time is recorded as the start time point of blood collection. As the blood collection process continues, the transmittance remains at a low level. When blood collection is completed, the amount of blood in the blood collection tube 120 decreases and the transmittance begins to rise. If the transmittance increases for the first time and the increase exceeds 5%, for example, from 80% to 85%, the time at this time is recorded as the end time point of blood collection.

[0050] In one embodiment, the third threshold ΔT3 and the fourth threshold ΔT4 can be adjusted according to actual application conditions to ensure that the start and end times of blood sampling can be accurately captured, which is not limited here.

[0051] Please also read Figure 3 , Figure 4 and Figure 5 In one embodiment, the method further includes S220: displaying at least one of the blood sampling start time point, the blood sampling end time point, and the light transmittance collected by the light transmission sensor 140 on the visual interface 150 .

[0052] By designing a user-friendly graphical interface to display relevant information of the blood collection process in real time, users can more intuitively understand the key time nodes of the blood collection process and the changing trend of transmittance, which helps to improve the monitoring efficiency and accuracy of the blood collection process.

[0053] In one embodiment, the visualization interface 150 may only display the start time of blood sampling, or only display the end time of blood sampling, or only display the light transmittance collected by the light transmission sensor 140, so that the user can intuitively understand the parameters they want to obtain.

[0054] In another embodiment, the blood sampling start time point, the blood sampling end time point and the light transmittance collected by the light transmission sensor 140 can be displayed in the visualization interface 150, thereby enriching the content displayed in the visualization interface 150.

[0055] Please continue reading Figure 3 , Figure 4 and Figure 5 In one embodiment, the light transmittance collected by the light transmittance sensor 140 can be presented in the visualization interface 150 in the form of a curve, that is, a curve graph showing the change of light transmittance over time is drawn in real time, so that the change of light transmittance can be intuitively presented in the visualization interface 150 through the change of the curve. At the same time, special marks can be used on the light transmittance curve to indicate the start time point and the end time point of blood collection, so that the user can intuitively see the start time point and the end time point of blood collection on the light transmittance curve. Among them, the color and style of the light transmittance curve can be customized according to actual needs to enhance the readability of the visualization interface 150.

[0056] In other embodiments, the transmittance collected by the light transmittance sensor 140 may also display a transmittance variation trend in a list or other form, which is not limited here.

[0057] In one embodiment, the positions of the first threshold T1, the third threshold ΔT3, the second threshold T2 and the fourth threshold ΔT4 may also be marked on the transmittance curve in the visualization interface 150, so that the user can intuitively see the difference between the transmittance currently obtained by the transmittance sensor 140 and the first threshold T1, the third threshold ΔT3, the second threshold T2 and the fourth threshold ΔT4, and at the same time enable the user to intuitively understand when the first threshold T1, the third threshold ΔT3, the second threshold T2 and the fourth threshold ΔT4 are reached.

[0058] In one embodiment, the visualization interface 150 may also provide an option for the user to view historical data of previous blood collection processes to help analyze abnormal situations in the blood collection process.

[0059] In one embodiment, the visualization interface 150 may also allow the user to export data records of the blood collection process for further analysis or archiving.

[0060] In actual application, the visualization interface 150 can update the information of the blood sampling process in real time, including the change of light transmittance, the determination of the start time point of blood sampling and the end time point of blood sampling. As the blood sampling process proceeds, the light transmittance curve formed by the change of light transmittance is updated in real time, and the start time point of blood sampling and the end time point of blood sampling are highlighted with specific marks on the light transmittance curve. The start time point of blood sampling and the end time point of blood sampling can also be displayed in clear text on the visualization interface 150, so that users can quickly check the key time points.

[0061] In one embodiment, the method further includes S230: saving at least one of the start time point of blood sampling, the end time point of blood sampling, and the change in transmittance.

[0062] By saving the start time of blood collection, the end time of blood collection, and the change in transmittance during the blood collection process, key information in the blood collection process can be accurately recorded for subsequent analysis or quality control. When problems arise in the subsequent blood collection results, the saved data can be used to trace the entire blood collection process to help diagnose the cause of the problem. At the same time, the saved data can be used to verify whether the blood collection process complies with the standard operating procedure (SOP), thereby ensuring the quality of blood collection.

[0063] In one embodiment, only the start time point of blood sampling may be saved, or only the end time point of blood sampling may be saved, or only the transmittance collected by the light transmission sensor 140 may be saved, so that the user can directly store the parameters that he wants to check later.

[0064] In another embodiment, the blood sampling start time point, the blood sampling end time point and the light transmittance collected by the light transmission sensor 140 can all be saved, thereby enriching the content that can be consulted later.

[0065] In one embodiment, the methods for saving the start time point of blood collection, the end time point of blood collection, and the change in transmittance include main body storage, cloud storage, log files, databases, etc., which are not limited here.

[0066] Among them, local storage refers to saving data in the built-in memory of the device, such as on the flash memory or hard disk of the blood collection device 100. Cloud storage refers to uploading data to a cloud server through the network for backup, which is convenient for users to remotely access and manage. Log file refers to creating a log file to record the data of each blood collection process, and each file contains a complete record of the blood collection process. Database refers to the use of a database management system (DBMS) to organize and store data, which is convenient for efficient retrieval and processing of large amounts of data.

[0067] See also Figure 5 In one embodiment, the method further includes S240: sending at least one of the start time point of blood sampling, the end time point of blood sampling, and the change in transmittance to the central medical information system 160.

[0068] Integrate key data of the blood collection process into the central medical information system 160 to realize centralized management and analysis of blood collection data, and conduct statistical analysis of historical data through the central medical information system 160 to identify potential problems in the blood collection process, optimize the blood collection process, and ensure that the blood collection process meets quality standards.

[0069] In one embodiment, only the start time of blood sampling may be sent, or only the end time of blood sampling may be sent, or only the transmittance collected by the light transmittance sensor 140 may be sent, so that the central medical information system 160 can directly obtain the parameters that need to be consulted later.

[0070] In another embodiment, the blood sampling start time point, the blood sampling end time point and the light transmittance collected by the light transmittance sensor 140 can all be sent to the central medical information system 160, thereby enriching the content that can be consulted later.

[0071] In one embodiment, the method of sending the blood collection start time point, blood collection end time point, and transmittance change to the central medical information system 160 includes wireless transmission, wired transmission, cloud service, etc., which is not limited here.

[0072] Among them, wireless transmission refers to sending the blood collection data to the central medical information system 160 via Wi-Fi, Bluetooth or other wireless communication technologies. Wired transmission refers to sending the blood collection data to the central medical information system 160 via a USB interface or Ethernet cable. Cloud service refers to uploading data to the cloud using the API interface of the cloud service provider, and then synchronizing the data to the central medical information system 160 from the cloud.

[0073] See also Figure 6 The present application also provides a blood collection system 300, which includes a blood collection device 100 and a processor 310. The blood collection device 100 includes a blood collector 110, a blood collection tube 120 connected to the blood collector 110, a light source 130 disposed on one side of the blood collection tube 120, and a light transmission sensor 140 disposed on the other side of the blood collection tube 120 and used to receive light emitted by the light source 130. The processor 310 is electrically connected to the light transmission sensor 140, and is used to obtain the light transmittance collected by the light transmission sensor 140, and determine the blood collection start time point and blood collection end time point of the blood collection device 100 according to the light transmittance.

[0074] In the above-mentioned blood collection system 300, the light source 130 irradiates light through the blood collection tube 120 toward the light transmission sensor 140, and the light transmission sensor 140 receives the light passing through the blood collection tube 120 and obtains its light intensity. At the same time, the light transmission sensor 140 converts the light intensity into an electrical signal and transmits it to the processor 310. The processor 310 calculates the transmittance according to the received electrical signal, and the processor 310 determines the start time point and the end time point of blood collection according to the change of the transmittance. Through the above-mentioned design, the blood collection system 300 can effectively monitor the blood collection process and automatically record the key time points, providing reliable support for recording the blood collection time.

[0075] Please continue reading Figure 6 In one embodiment, the blood collection system 300 further includes:

[0076] The storage unit 320 is electrically connected to the processor 310, and is used to store at least one of the blood sampling start time point, the blood sampling end time point, and the light transmittance.

[0077] The visualization interface 330 is electrically connected to the processor 310 and is used to display at least one of the start time point of blood sampling, the end time point of blood sampling, and the transmittance.

[0078] The communication unit 340 is electrically connected to the processor 310 and is used to send at least one of the blood sampling start time point, the blood sampling end time point, and the transmittance to the central medical information system 160.

[0079] The calibration unit 350 is electrically connected to the processor 310 and is used to calibrate at least one of the blood sampling start time point, the blood sampling end time point, and the light transmittance. The user can set the calibration cycle according to actual needs to ensure the accuracy of the data. Or the calibration unit 350 can adjust the first threshold T1, the second threshold T2, the third threshold ΔT3, and the fourth threshold ΔT4 to adapt to different blood sampling environments and blood sampling needs.

[0080] Through the above design, the blood collection system 300 can not only accurately record the key information of the blood collection process, but also realize functions such as data storage, display, transmission and calibration through expansion components, which greatly improves the efficiency and quality of the blood collection process.

[0081] Please also read Figure 3 and Figure 6 In one embodiment, the processor 310 is specifically used to: in response to the transmittance decreasing to less than the first threshold value T1, determine the current time point as the start time point of blood sampling; and in response to the transmittance increasing to greater than the second threshold value T2, determine the current time point as the end time point of blood sampling.

[0082] The processor 310 continuously receives data from the light transmission sensor 140, which reflects the change of light transmittance during the blood sampling process. The processor 310 compares the current light transmittance with the first threshold T1 and the second threshold T2 to determine whether the current time point is the start time point of blood sampling or the end time point of blood sampling.

[0083] Please also read Figure 4 and Figure 6 In another embodiment, the processor 310 is specifically used to: in response to a decrease in transmittance and the decrease in transmittance is greater than a third threshold value ΔT3, determine the current time point as the start time point of blood sampling; and in response to an increase in transmittance and the increase in transmittance is greater than a fourth threshold value ΔT4, determine the current time point as the end time point of blood sampling.

[0084] The processor 310 compares the current change in transmittance with the third threshold ΔT3 and the fourth threshold ΔT4, thereby determining whether the current time point is the start time point of blood sampling or the end time point of blood sampling. Through the above design and implementation, the processor 310 can effectively monitor the blood sampling process and automatically record key time points, providing reliable support for recording the blood sampling time.
