Description

Technical Field

[0001] The present application relates to the field of terminal technology, and in particular to a method, device, equipment, medium and program product for preparing a plasma matrix. Background Art

[0002] Plasma matrix usually refers to the liquid components of plasma other than blood cells. It is a complex biological fluid that contains a variety of proteins, electrolytes, nutrients, metabolic wastes and various bioactive molecules, etc. It plays an important role in maintaining the normal physiological functions and internal environment stability of the human body. Plasma matrix can be used to promote postoperative wound healing, relieve postoperative pain, osteoarthritis injection treatment, facial beauty, soft tissue regeneration, bone regeneration, etc.

[0003] Since the plasma matrix was first introduced, it has undergone three major modifications. The fourth-generation plasma matrix, which is currently the most widely used, has shown unique advantages in terms of the quantity and preservation of internal bioactive components. The fourth-generation plasma matrix is ​​currently divided into two types: liquid plasma matrix and solid plasma matrix. During clinical treatment, some patients have a demand for both forms of products. Especially for solid plasma matrix, individual differences among patients often lead to insufficient platelet activation, weak fiber network formation, and even inability to coagulate in clinical practice.

[0004] The traditional solution to this situation is to extend the centrifugation time, but the extension of the centrifugation time will also bring many problems. First, too long centrifugation will promote the coagulation of liquid plasma matrix, resulting in failure to obtain the two products and difficulty in forming plasma matrix bone blocks in the later stage; secondly, extending the centrifugation time will increase the waiting time for patients and doctors; in addition, the preparation of traditional plasma matrix is ​​affected by the dual factors of centrifugal force and time.

[0031] In order to more clearly illustrate the technical solutions in the embodiments of the present application or the prior art, the technical terms required to be used in the embodiments or the prior art description are briefly introduced below:

[0032] The absorbance of plasma matrix refers to the degree of absorption of light by plasma under the irradiation of light of a specific wavelength. Absorbance is usually represented by the symbol A, and its relationship with transmittance (T) is A=-logT. When light passes through the plasma matrix, various components in the plasma (such as proteins, lipids, metabolites, etc.) will absorb light of a certain wavelength, thereby weakening the intensity of the transmitted light.

[0033] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present application, rather than all of the embodiments.

[0035] In order to solve some or all of the technical problems existing in the related art, the embodiment of the present application provides a method, device, equipment, medium and program product for preparing a plasma matrix, wherein the method is applied to a plasma matrix preparation platform including an optical detection probe, and the optical detection probe is used to detect the absorbance of the plasma matrix in real time. The method first performs preliminary centrifugation on multiple tubes of whole blood samples according to the initial preparation parameters to obtain multiple tubes of primary plasma matrix; then adjust the preparation parameters according to the absorbance of the primary plasma matrix detected by the optical detection probe, wherein there is a linear relationship between the absorbance and the preparation parameters; further centrifuge the primary plasma matrix according to the adjusted preparation parameters until the change trend of the absorbance of the plasma matrix tends to be stable, and then obtain solid plasma matrix and liquid plasma matrix at the same time. In this way, the embodiment of the present application can ensure the formation of the solid plasma matrix by detecting the absorbance of the plasma matrix in real time, adjusting the preparation parameters according to the linear relationship between the absorbance and the preparation parameters, and obtaining two forms of plasma matrix products that meet clinical needs at the same time after the centrifugation, shortening the centrifugation time to a certain extent, and improving the preparation efficiency and effect of the plasma matrix.

[0036] A method for preparing a plasma matrix provided in the embodiments of the present application can be implemented by a preparation device or electronic device of the plasma matrix, and the electronic device includes but is not limited to a personal computer, a laptop computer, a tablet computer, a smart phone, etc. The operating system of the electronic device may include Android (Android), a mobile operating system (iOS) developed by Apple, an operating system (Windows) developed by Microsoft Corporation of the United States, etc., and the embodiments of the present application are not limited to this. The electronic device can be operated alone to implement the present application, or it can be connected to the network and implemented by interactive operations with other computer devices in the network. Among them, the network in which the electronic device is located includes but is not limited to the Internet, a wide area network, a metropolitan area network, a local area network, a virtual private network (Virtual Private Network, VPN) network, etc.

[0037] It should be noted that the protection scope of the method for preparing a plasma matrix described in the embodiment of the present application is not limited to the execution order of the steps listed in this embodiment. All solutions implemented by adding, reducing or replacing steps in the prior art based on the principles of the present application are included in the protection scope of the present application.

[0038] like Figure 1 As shown, Figure 1 The present invention is a flow chart of a method for preparing a plasma matrix according to an embodiment of the present invention. The method can be performed by a plasma matrix preparation device, wherein the device can be implemented by software and / or hardware and can generally be integrated in an electronic device. The device or electronic device runs a plasma matrix preparation platform, and the plasma matrix preparation platform includes an optical detection probe for real-time detection of the absorbance of the plasma matrix.

[0039] The method mainly includes the following steps S101 to S103:

[0040] S101. Perform preliminary centrifugation on multiple tubes of whole blood samples according to initial preparation parameters to obtain multiple tubes of primary plasma matrix.

[0041] The initial preparation parameters include centrifugal force and centrifugal time. The initial centrifugal force can be 1-3000g.

[0042] Exemplarily, the initial preparation parameters include a centrifugal force of 2000g-3000g and a centrifugal time of 10-15 minutes, or a centrifugal force of 1000g-1500g and a centrifugal time of 8-12 minutes, etc. This application is only for exemplary description and does not specifically limit the initial preparation parameters.

[0043] In some embodiments, the liquid level of the primary plasma matrix obtained after the initial centrifugation is lower than the liquid level of the whole blood sample and is located within a preset range below the liquid level of the whole blood sample. The preset range can be 2-57 mm. Exemplarily, the liquid level of the primary plasma matrix is ​​2 mm lower than the liquid level of the whole blood sample.

[0044] The multiple tubes of whole blood samples include: a first whole blood sample collected by a solid plasma matrix preparation tube, and a second whole blood sample collected by a liquid plasma matrix preparation tube. The solid plasma matrix preparation tube can be a glass blood collection tube, and the liquid plasma matrix preparation tube can be a plastic blood collection tube. It is understood that venous blood is collected using a solid plasma matrix preparation tube and a liquid plasma matrix preparation tube, respectively.

[0045] Exemplarily, the multiple tubes of whole blood samples include a first whole blood sample collected by 4 glass blood collection tubes and a second whole blood sample collected by 2 plastic blood collection tubes, each of which contains 10 ml of venous blood.

[0046] In some embodiments, the detection wavelength of the optical detection probe is set to a preset wavelength range so that the optical detection probe can detect the absorbance of the primary plasma matrix in real time within the preset wavelength range. The preset wavelength range can be 490-500nm, or 450-480nm. The step of setting the detection wavelength of the optical detection probe can be performed before or at the same time as step S101, but must be performed before step S102.

[0047] Exemplarily, the detection wavelength range of the optical detection probe is set to 490-500 nm, and when the liquid level of the primary plasma matrix in the solid plasma matrix preparation tube is 2 mm lower than the liquid level of the whole blood sample, the absorbance of the primary plasma matrix is ​​detected; another exemplary embodiment, the detection wavelength range of the optical detection probe is set to 450-480 nm, and when the liquid level of the primary plasma matrix in the liquid plasma matrix preparation tube is 7 mm lower than the liquid level of the whole blood sample, the absorbance of the primary plasma matrix is ​​detected.

[0048] S102. Adjust the preparation parameters according to the absorbance of the primary plasma matrix detected by the optical detection probe.

[0049] The optical detection probe is used to detect the absorbance of the plasma matrix in real time. There is a linear relationship between the preparation parameters and the absorbance of the primary plasma matrix.

[0050] In some embodiments, during the execution of step S102, the absorbance of the primary plasma matrix detected by the optical detection probe is obtained according to a preset accuracy, and then the preparation parameters are adjusted based on the absorbance.

[0051] Exemplarily, during the execution of step S102, when the liquid level of the primary plasma matrix is ​​lower than the liquid level of the whole blood sample D1=2mm, the absorbance detected by the optical detection probe is obtained; when the liquid level of the primary plasma matrix is ​​lower than the liquid level of the whole blood sample D2=7mm, the absorbance detected by the optical detection probe is obtained; when the liquid level of the primary plasma matrix is ​​lower than the liquid level of the whole blood sample D3=12mm, the absorbance detected by the optical detection probe is obtained; when the liquid level of the primary plasma matrix is ​​lower than the liquid level of the whole blood sample D4=17mm, the absorbance detected by the optical detection probe is obtained; when the liquid level of the primary plasma matrix is ​​lower than the liquid level of the whole blood sample D5=22mm, the absorbance detected by the optical detection probe is obtained; when the liquid level of the primary plasma matrix is ​​lower than the liquid level of the whole blood sample D6=27mm, the absorbance detected by the optical detection probe is obtained. The absorbance detected by the optical detection probe is obtained when the liquid level of the primary plasma matrix is ​​lower than the liquid level of the whole blood sample D7 = 32 mm; when the liquid level of the primary plasma matrix is ​​lower than the liquid level of the whole blood sample D8 = 37 mm, the absorbance detected by the optical detection probe is obtained; when the liquid level of the primary plasma matrix is ​​lower than the liquid level of the whole blood sample D9 = 42 mm, the absorbance detected by the optical detection probe is obtained; when the liquid level of the primary plasma matrix is ​​lower than the liquid level of the whole blood sample D10 = 47 mm, the absorbance detected by the optical detection probe is obtained; when the liquid level of the primary plasma matrix is ​​lower than the liquid level of the whole blood sample D11 = 52 mm, the absorbance detected by the optical detection probe is obtained; when the liquid level of the primary plasma matrix is ​​lower than the liquid level of the whole blood sample D12 = 57 mm, the absorbance detected by the optical detection probe is obtained. The preparation parameters are then adjusted based on these absorbances.

[0052] In some embodiments, when the absorbance of the detected primary plasma matrix no longer decreases significantly within a preset time, the preparation parameters are adjusted. The preset time can be 30 seconds, and the present application does not specifically limit this. Specifically, the average decrease in the absorbance of the primary plasma matrix within the preset time is calculated, and the average decrease is compared to see whether it is less than the preset decrease. If so, it means that the absorbance no longer decreases significantly within the preset time, and the preparation parameters are adjusted at this time.

[0053] Continuing with the previous example, when it is detected that the absorbance of the primary plasma matrix at D1-D12 no longer decreases significantly within 30 seconds, the initial preparation parameters are adjusted. If the centrifugal force of the initial preparation parameters is 1500g, the adjustment value is 450g.

[0054] Exemplarily, when the monitoring process finds that the absorbance detected by the optical detection probe at the position of 2-57 mm no longer decreases significantly for 30 consecutive seconds, the adjustment parameter is set to the low centrifugal force program, and the centrifugal force is adjusted from the initial value of 1500g to 450g.

[0055] S103. Centrifuge the primary plasma matrix according to the adjusted preparation parameters until the absorbance change trend of the plasma matrix tends to be stable, so as to obtain a solid plasma matrix and a liquid plasma matrix.

[0056] Among them, the solid plasma matrix is ​​a plasma matrix in a gel-like state, and the liquid plasma matrix is ​​a plasma matrix that can maintain a liquid state for more than 60 minutes.

[0057] It should be noted that when centrifugation is not completed, the decrease in the absorbance of the plasma matrix is ​​very obvious, and the absorbance at the same position detected at different times within the preset detection wavelength range will differ by several times. In some embodiments, when the absorbance at D1 to D12 detected by the optical detection probe with a detection wavelength within 490-500nm is stabilized at a minimum value, and the absorbance at D1 to D12 detected by the optical detection probe with a detection wavelength within 450-480nm is stabilized at a maximum value, it indicates that the preparation is complete, and a solid plasma matrix and a liquid plasma matrix are obtained at the same time.

[0058] Exemplarily, when the absorbance at D1~D12 detected by the optical detection probe with a detection wavelength within 490-500nm is stabilized at a minimum value of 1.81, and the absorbance at D1~D12 detected by the optical detection probe with a detection wavelength within 450-480nm is stabilized at a maximum value of 2.30, solid plasma matrix and liquid plasma matrix are obtained at the same time.

[0059] As another example, when the absorbance at D1~D12 detected by the optical detection probe with a detection wavelength within 490-500nm is stabilized at a minimum value of 1.95, and the absorbance at D1~D12 detected by the optical detection probe with a detection wavelength within 450-480nm is stabilized at a maximum value of 2.57, solid plasma matrix and liquid plasma matrix are obtained at the same time.

[0060] It should be noted that the above minimum and maximum values ​​are only exemplary and are not specifically limited in this application.

[0061] In some embodiments, the primary plasma matrix is ​​centrifuged according to the adjusted preparation parameters, and the absorbance of the plasma matrix is ​​continuously detected during the process. Optionally, a graph is drawn based on the absorbance of the detected plasma matrix to show the change trend of the absorbance. The absorbance at different positions corresponds to different absorbance curves with time as the horizontal coordinate and the vertical coordinate as the vertical coordinate, so as to quantitatively analyze the change trend of the absorbance. Optionally, the variance and / or standard deviation of the absorbance of the plasma matrix are calculated. If the variance approaches a smaller value, it means that the absorbance of the plasma matrix tends to be stable. If the standard deviation approaches 0, it means that the absorbance is increasingly concentrated near a fixed value, and the change trend tends to be stable. Optionally, the average rate of change of the absorbance of the plasma matrix within a preset time interval is calculated, or a preset mathematical function is selected for curve fitting. The preset mathematical function can be an exponential function, and the derivative of the fitting curve is used to determine whether the change trend of the absorbance tends to be stable. When the change trend tends to be stable, the centrifugation can be controlled to end, and at this time, two states of plasma matrix can be obtained at the same time.

[0062] In summary, the embodiment of the present application provides a method for preparing a plasma matrix, which is applied to a plasma matrix preparation platform including an optical detection probe, and the optical detection probe is used to detect the absorbance of the plasma matrix in real time. The method first performs preliminary centrifugation on multiple tubes of whole blood samples according to the initial preparation parameters to obtain multiple tubes of primary plasma matrix; then adjust the preparation parameters according to the absorbance of the primary plasma matrix detected by the optical detection probe, wherein there is a linear relationship between the absorbance and the preparation parameters; further centrifuge the primary plasma matrix according to the adjusted preparation parameters until the change trend of the absorbance of the plasma matrix tends to be stable, and then obtain solid plasma matrix and liquid plasma matrix at the same time. In this way, the embodiment of the present application can ensure the formation of the solid plasma matrix by detecting the absorbance of the plasma matrix in real time, and adjusting the preparation parameters according to the linear relationship between the absorbance and the preparation parameters. After the centrifugation, two forms of plasma matrix products that meet clinical needs are obtained at the same time, shortening the centrifugation time to a certain extent, and improving the preparation efficiency and effect of the plasma matrix.

[0063] To further reflect the technical effect of the embodiment of the present application, a comparative test was conducted with the preparation method of the existing plasma matrix, using 4 glass blood collection tubes and 2 plastic blood collection tubes to collect 60mL of human blood, each blood collection tube 10mL. The plasma preparation method of the present application and the existing method were applied respectively. The solid plasma matrix coagulation time and liquid plasma matrix coagulation time of the embodiment of the present application and the existing method (as a comparative example) were recorded, and after the operation, for the preparation scheme of this plasma matrix, the doctor was invited to perform visual simulation scoring. The doctor needed to draw a hash mark representing their satisfaction on the unmarked 10 cm line, with the left side marked as "very dissatisfied" and the right side marked as "very satisfied". The satisfaction score is the distance from the left end of the line (in millimeters). In the comparative test, 6 parallel samples were taken for each data, and the test results were averaged.

[0064] Among them, the solid plasma matrix coagulation time is from the time the whole blood is put into the equipment for operation until the solid plasma matrix is ​​completely coagulated. The liquid plasma matrix coagulation time is from the time the solidified solid plasma matrix is ​​obtained to the time the liquid plasma matrix begins to coagulate. It should be noted that a long coagulation time of the liquid plasma matrix will make the coagulation factor detection more accurate, and it is also convenient for multiple items to be jointly tested, which can extend the storage time and reduce the risk of blood transfusion. The Visual Analogue Scale (VAS) is a tool used to assess the degree of pain or other subjective feelings (such as itching, fatigue, etc.). It mainly uses a straight line with a scale to let the subject subjectively express the intensity of his feelings. Using the VAS scale, the subjective feeling information of the subject can be obtained very intuitively.

[0065] Through the above comparative test, Figure 2 The comparison chart of the overall preparation time is shown in Figure 3 Comparison of clotting times of liquid plasma matrices, Figure 4 The comparison chart of the VAS score of doctor satisfaction shown in the figure shows that the overall preparation time of the present application is significantly shortened, the coagulation time of the liquid plasma matrix is ​​longer, and the VAS score of doctor satisfaction is higher.
