优选地，联通器3为三通管，三通管的第一端口301与试剂卡6连接，三通管的第二端口302与压力传感器2连接，三通管的第三端口303与驱动器4连接，通过设置联通器3行成互通，使得在驱动器4吸取血液过程中，压力传感器2的数值也会随之变化，红细胞积压情况可以通过实时监测压力变化信号来获得，反应比较迅速。Preferably, the connector 3 is a three-way tube, the first port 301 of the three-way tube is connected to the reagent card 6, the second port 302 of the three-way tube is connected to the pressure sensor 2, and the third port 303 of the three-way tube is connected to the driver 4. By setting the connector 3 to be interconnected, the value of the pressure sensor 2 will change during the process of the driver 4 sucking blood, and the red blood cell overload situation can be obtained by real-time monitoring of the pressure change signal, and the response is relatively rapid.
优选地，驱动器4为压电泵，压电泵与控制系统5电性连接，通过调节压电泵的工作参数，如电压，可以精确控制血液流动的速率和量，实现稳定而准确的操作。Preferably, the driver 4 is a piezoelectric pump, which is electrically connected to the control system 5. By adjusting the working parameters of the piezoelectric pump, such as voltage, the rate and amount of blood flow can be accurately controlled to achieve stable and accurate operation.
可以理解，仪器本体1内置有压力传感器2、联通器3、驱动器4以及控制系统5，通过将试剂卡6与压力传感器2、驱动器4连接，利用驱动器4控制血液流速过程中记录压力传感器2的数值变化，搭配公式算法，从而测出红细胞的积压；在本申请中，使用压力传感器2检测方法对红细胞积压进行检测，不需要直接接触或损伤红细胞，对样本的物理性质没有破坏；红细胞积压情况可以通过实时监测压力变化信号来获得，反应比较迅速；同时，利用压力传感器2可提供较高的检测精度，对于微小的压力变化也能进行灵敏监测。It can be understood that the instrument body 1 has built-in pressure sensor 2, connector 3, driver 4 and control system 5. By connecting the reagent card 6 with the pressure sensor 2 and driver 4, the value change of the pressure sensor 2 is recorded during the process of controlling the blood flow rate by the driver 4, and the red blood cell overload is measured by combining with the formula algorithm; in the present application, the red blood cell overload is detected by the pressure sensor 2 detection method, which does not require direct contact or damage to the red blood cells and does not damage the physical properties of the sample; the red blood cell overload situation can be obtained by real-time monitoring of the pressure change signal, and the response is relatively rapid; at the same time, the pressure sensor 2 can provide higher detection accuracy, and can also sensitively monitor small pressure changes.
请参照图1，在上述实施例的基础上还提供了另外一种实施例，在本实施例中，驱动器4包括注射器以及电动推杆，注射器与电动推杆设置在仪器本体1内部，电动推杆的输出端与注射器的输出端连接。Please refer to Figure 1. Another embodiment is provided based on the above embodiment. In this embodiment, the driver 4 includes a syringe and an electric push rod. The syringe and the electric push rod are arranged inside the instrument body 1, and the output end of the electric push rod is connected to the output end of the syringe.
可以理解，电动推杆与控制系统5连接，控制系统5用于控制电动推杆的运行，电动推杆与注射器输出端固定连接，通过控制电动推杆的伸缩距离实现对注射器上注射杆移动距离的调节，利用注射器吸取血液移动的工作原理是通过改变注射器内部的压力差来实现血液样本的吸取，通过在吸取血液样本移动过程中，压力传感器2数值的变化，搭配公式算法，从而测出红细胞的积压。It can be understood that the electric push rod is connected to the control system 5, and the control system 5 is used to control the operation of the electric push rod. The electric push rod is fixedly connected to the output end of the syringe. The movement distance of the injection rod on the syringe is adjusted by controlling the telescopic distance of the electric push rod. The working principle of using the syringe to absorb blood and move is to achieve the absorption of blood samples by changing the pressure difference inside the syringe. The change in the value of the pressure sensor 2 during the process of sucking the blood sample is combined with the formula algorithm to measure the red blood cell backlog.
请参照图3，图4，一种基于压力检测红细胞积压的试剂卡6，适用于上述的一种集成凝血和免疫检测仪器，试剂卡6上设置有样品通道，样品通道的一端设置有进样口602，样本通道601的另一端设置有微型泵接口603。Please refer to Figures 3 and 4, a reagent card 6 for pressure-based detection of hematocrit is suitable for the above-mentioned integrated coagulation and immunoassay instrument. A sample channel is provided on the reagent card 6, an injection port 602 is provided at one end of the sample channel, and a micro pump interface 603 is provided at the other end of the sample channel 601.
优选地，还包括滤板，进样口602上设置有滤板，滤板用于对加入的样本进行气泡过滤，滤板能将携带有气泡的血液进行过滤，减少气泡进入样本通道601中。Preferably, a filter plate is further included. The sample inlet 602 is provided with a filter plate, and the filter plate is used to filter bubbles in the added sample. The filter plate can filter the blood carrying bubbles to reduce the bubbles entering the sample channel 601 .
优选地，还包括突刺，滤板上设置有多个突刺，多个突刺尺寸大小不一，突刺用于刺破加入样本中携带的气泡，进一步减少气泡进入样品通道中，提供检测精度。Preferably, it also includes thorns. The filter plate is provided with a plurality of thorns of different sizes. The thorns are used to puncture the bubbles carried in the added sample, further reducing the bubbles entering the sample channel and improving the detection accuracy.
可以理解，将血液滴入进样口602中，血液在与滤板以及突刺接触过程中，血液如果携带有气泡会被滤板以及突刺进行过滤和刺破，减少气泡进入到样品通道中，利用微型泵接口603与第一端口301联通，在压电泵的吸取下，血液进入样本通道601中，并在样本通道601中移动指定距离。It can be understood that when blood is dripped into the sampling port 602, the blood will be filtered and punctured by the filter plate and the thorns if it carries bubbles during the contact with the filter plate and the thorns, thereby reducing the bubbles from entering the sample channel. The micro pump interface 603 is connected to the first port 301, and under the suction of the piezoelectric pump, the blood enters the sample channel 601 and moves a specified distance in the sample channel 601.
综上，驱动器4吸取血液过程中会引起压力传感器的数值变化，不同浓度的红细胞压积会有不同的压力变化形态，通过对压力变化的趋势，从而计算出红细胞压积；当血液添加到试剂卡6的进样口602后，在压电泵未吸取血液流动前先记录此时压力传感器2的数值，并标记为PS0，然后控制压电泵让血液流动一段固定距离，记录流动后的压力传感器2数值为PS1，通过流动前后的压力差PS=PS1-PS0和区间压力变化速率PsV。在临床实验数据中发现，随着血液中红细胞的占比越高，血液流动相同距离产生的压力变化越大、变化速率越快。In summary, the driver 4 will cause the value of the pressure sensor to change during the process of absorbing blood. Different concentrations of hematocrit will have different pressure change forms. The hematocrit can be calculated by the trend of pressure change. When blood is added to the inlet 602 of the reagent card 6, the value of the pressure sensor 2 is recorded before the piezoelectric pump absorbs the blood flow and is marked as PS0. Then the piezoelectric pump is controlled to let the blood flow for a fixed distance, and the value of the pressure sensor 2 after the flow is recorded as PS1. The pressure difference before and after the flow is PS=PS1-PS0 and the interval pressure change rate PsV. It is found in clinical experimental data that as the proportion of red blood cells in the blood increases, the pressure change caused by the same distance of blood flow is greater and the change rate is faster.
请参照图5，图5为0%、10%、20%、30%、40%、50%、60%、70%、80%红细胞压积流动相同距离时流道内部压力变化图；通过以0%红细胞压积的压力变化和变化速率作为基准，把当前测试所得的压力变化PS和变化速率PsV代入算法计算得出所测血液的红细胞压积。Please refer to Figure 5, which is a diagram of the pressure change inside the flow channel when the hematocrit flows for the same distance at 0%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, and 80%. By taking the pressure change and change rate of 0% hematocrit as a benchmark, the pressure change PS and change rate PsV obtained from the current test are substituted into the algorithm to calculate the hematocrit of the measured blood.
