Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically to an automatic shaking device for apheresis concentrated platelets. Background Technology

[0002] Platelet apheresis is a process where platelets are automatically separated from the blood of eligible donors and suspended in a certain amount of plasma using a blood cell separator under completely enclosed conditions. Centrifugal blood cell separators are currently the most widely used method for collecting platelets, accounting for over 90% of all separators used domestically and internationally. Most imported and domestically produced separators in my country are centrifugal type. The separation principle is based on the different specific gravities of various blood components. Through centrifugal forces, plasma components and blood cell components such as red blood cells, granulocytes, lymphocytes, and platelets are separated into layers, allowing the extraction of desired components or the removal of pathological components. The remaining components are then returned to the donor or patient.

[0003] The advantages of using a centrifugal platelet separator to collect apheresis platelets are: 1. Apheresis platelets save donors compared to traditionally prepared manual platelets, conserving valuable blood resources. 2. Using high-concentration apheresis platelets results in significantly better clinical efficacy than traditionally prepared manual platelets, greatly reducing the probability of transfusion-transmitted infectious diseases. From an immunological perspective, it reduces the stimulation of multiple allogeneic antigens on patients, lowers the rate of alloantibody production, and significantly reduces the incidence of non-hemolytic febrile transfusion reactions and immune platelet transfusion ineffectiveness. 3. It has good efficacy and fewer adverse reactions. During the collection of concentrated apheresis platelets, because ultra-high concentration platelets are collected in a narrow and compressed collection bag, most platelets are compressed into clumps of varying sizes instead of being individually scattered. This makes it impossible to accurately detect the concentrated platelet count, resulting in a low detected platelet count that does not meet quality requirements, causing economic losses due to blood waste, and also hindering platelet preservation and uniform bagging. The problem of platelets clumping together is currently addressed through manual shaking and visual inspection. However, manual shaking has several drawbacks: First, prolonged vigorous shaking with both arms and visual inspection of platelets held high can cause serious damage to the arms, shoulders, and neck of staff. Second, visual inspection to determine if the clumps are evenly dispersed is subjective and difficult to control. Third, this process requires repeated manual shaking, settling, and observation, which is time-consuming, requires significant manpower, and reduces the efficiency of the platelet collection team. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an automatic shaking device for apheresis concentrated platelets to solve the problems existing in the background art.

[0005] The present invention provides the following technical solution: an automatic shaking device for concentrated platelets collected by apheresis, comprising a main body, wherein a limiting mechanism is installed at the middle position of the inner wall of the main body, and an adjustment mechanism is provided on the inner wall of the limiting mechanism;

[0006] The main body includes a housing, and a control device is installed on the front of the housing. The control device is equipped with a control system, which controls the main body and the adjustment mechanism.

[0007] A sealing cover is installed on the top of the back of the box. An electrically controlled angle adjustment device is provided at the connection between the box and the sealing cover. The electrically controlled angle adjustment device drives the sealing cover to rotate so that the side of the sealing cover can be attached to the top of the box to form a sealed space. A bearing is installed on the inner wall of the box. A transmission rod is movably sleeved on the inner wall of the bearing. A servo motor is installed on the transmission rod away from the bearing. A support plate is installed on the outer wall of the middle of the transmission rod. Support frames are installed on the four sides of the top of the support plate. A colorimeter is installed in the middle of the top of the support plate. The colorimeter collects the colorimetric data U generated in each area of ​​the platelet collection bag and transmits it to the control system. A lighting device is installed in the middle of the bottom of the sealing cover.

[0008] Furthermore, the servo motor input current drives the transmission rod to move the support plate left and right, thereby driving the platelets in the collection bag to be shaken evenly.

[0009] Furthermore, the limiting mechanism includes a limiting frame, a placement plate welded to the bottom of the limiting frame, a lifting chamber installed on the inner wall of the limiting frame near the placement plate, a first electro-hydraulic column installed on the inner wall of the lifting chamber, a first sliding plate installed at the bottom of the first electro-hydraulic column, the first sliding plate being driven by the input current of the first electro-hydraulic column to move parallel inside the lifting chamber, an auxiliary limiting frame installed on the side of the first sliding plate, a limiting plate being movably sleeved at the bottom of the auxiliary limiting frame, and a spring installed on the limiting plate near the auxiliary limiting frame;

[0010] The inner wall of the side of the limiting frame is provided with two sets of sliding grooves.

[0011] Furthermore, the adjustment mechanism includes a main hollow plate, a slider welded to the bottom of the main hollow plate, the slider being movably fitted into two sets of grooves on the side of the limiting frame, a transmission screw threaded to the inner wall of the slider, a micro motor installed at one end of the transmission screw, a second electro-hydraulic column installed on the inner wall of the main hollow plate, an auxiliary hollow plate installed on the side of the second electro-hydraulic column, an electrically controlled lifting device installed on the inner wall of the auxiliary hollow plate, a rubber plate movably fitted to the inner wall of the auxiliary hollow plate, and the electrically controlled lifting device driving the rubber plate to move vertically inside the auxiliary hollow plate.

[0012] Furthermore, the micro motor input current drives the transmission screw to rotate, and the rotating transmission screw drives the slider to move parallel within the slide groove.

[0013] Furthermore, the control system includes a chromaticity data acquisition module, an analysis module, a threshold module, a control module, an execution module, and a DPS processor. The DPS processor performs calculations and controls on the chromaticity data acquisition module, the analysis module, the threshold module, the control module, and the execution module.

[0014] The colorimetric data acquisition module receives real-time colorimetric data U generated by platelets in various regions of the collection bag collected by the colorimeter and transmits it to the analysis module. The threshold module simulates the simulated colorimetric data Un generated by the colorimeter when the platelets in the collection bag are in a uniform state, and integrates the simulated colorimetric data Un to form a first threshold range. The threshold module simulates the simulated colorimetric data Uv generated by the colorimeter in a certain region when small clumps of platelets appear in the collection bag, and integrates the simulated colorimetric data Uv to form a second threshold range. The threshold module transmits the first threshold range and the second threshold range to the analysis module.

[0015] The analysis module compares the real-time colorimetric data U with the first threshold range and the second threshold range, and sends the comparison result to the control module. When the real-time colorimetric data U is not within the first threshold range, the control module determines that the platelets in the collection bag are in a non-uniform distribution state, and the control module issues a first decision to the execution module. When the real-time colorimetric data U is within the second threshold range, the control module determines that small platelet clumps appear in the area.

[0016] Furthermore, the execution module receives a quantitative current input from the first decision control main mechanism, which drives the platelets in the collection bag to continuously shake. The execution module also receives a second decision control adjustment mechanism to automatically shake the small clumps of platelets in the collection bag.

[0017] When the real-time colorimetric data is within the first threshold range, it can be determined that the platelets in the collection bag are in a uniform state. The control module sends a third decision to the execution module. The execution module receives the third decision and feeds it back to the DPS processor. The DPS processor controls the display on the surface of the control device to issue a reminder, reminding the staff that the platelets in the collection bag are in a uniform distribution state.

[0018] The technical effects and advantages of this invention are as follows:

[0019] This invention, by incorporating a main structure and a control system, facilitates the servo motor's input current driving the transmission rod to sway the support plate, support frame, and limiting mechanism left and right when the platelet collection bag is confined to the inner wall of the limiting mechanism. This, in turn, drives the platelets inside the collection bag to be shaken evenly. During the shaking process, the lighting device inputs current to assist the colorimeter in collecting colorimetric data U in each area of ​​the collection bag. The colorimetric data U collected by the colorimeter is transmitted to the control system, which determines whether the platelets inside the collection bag are in a shaking state based on the changes in the colorimetric data U.

[0020] This invention, by incorporating an adjustment mechanism and a control system, facilitates the following: When the control system detects the presence of small platelet clumps in a portion of the collection bag, it controls the micro-motor to input current, driving the transmission screw to rotate. In its optional state, the transmission screw drives the slider and main hollow plate to a designated position. Simultaneously, a second electro-hydraulic column and an electrically controlled lifting device input a fixed amount of current, driving two sets of rubber plates to move to both ends of the platelet collection bag. This automatically evenly distributes the collected platelets, preventing them from being in an unevenly distributed state, which would affect the accuracy of post-bag testing data and lead to the collected platelets failing to meet quality control requirements, thus resulting in blood waste and economic losses.

[0038] In this embodiment of the application, the specific workflow of this part of the application embodiment is as follows: the collection bag containing platelets is placed on the surface of the placement plate 202, the first electro-hydraulic column 204 inputs current to drive the first slide plate 205, the auxiliary limiting frame 206 and the limiting plate 207 to contact the surface of the collection bag, the limiting plate 207 drives the spring 208 to be in a compressed state, generating spring force, driving the limiting plate 207 to move to the position of the collection bag, thereby achieving the function of limiting and fixing the collection bag.

[0039] Reference Figure 3 as well as Figures 6 to 7 As shown, the present invention provides an automatic shaking device for apheresis concentrated platelets, including an adjusting mechanism 3. The adjusting mechanism 3 includes a main hollow plate 301, and a slider 303 is welded to the bottom of the main hollow plate 301. The slider 303 is movably sleeved in two sets of sliding grooves on the side of the limiting frame 201. A transmission screw 304 is threadedly connected to the inner wall of the slider 303. A micro motor 302 is installed at one end of the transmission screw 304. The micro motor 302 inputs current to drive the transmission screw 304 to rotate.

[0040] In this embodiment of the application, the specific workflow of this part of the application embodiment is as follows: When the control system 4 determines that platelet clumps appear in a certain area of ​​the collection bag, the control system 4 controls the micro motor 302 to input current, driving the transmission screw 304 to start rotating. The transmission screw 304 in the optional state drives the slider 303 and the main hollow plate 301 to move to the designated position. At the same time, the second electro-hydraulic column 305 and the electric lifting device input a quantitative current, driving the two sets of rubber plates 307 to move to the vicinity of the platelet clumps. The two sets of rubber plates 307 apply a slight external force to the platelet clumps to make them evenly dispersed, so as to avoid the platelet clumps from affecting the blood test data.

[0041] Reference Figure 8 As shown, the present invention provides an automatic shaking device for apheresis concentrated platelets, including a control system 4. The control system 4 includes a colorimetric data acquisition module 401, an analysis module 402, a threshold module 403, a control module 404, an execution module 405, and a DPS processor. The DPS processor performs calculations and controls on the colorimetric data acquisition module 401, the analysis module 402, the threshold module 403, the control module 404, and the execution module 405.

[0042] The colorimetric data acquisition module 401 receives real-time colorimetric data U generated by platelets in each region of the collection bag collected by the colorimeter 110 and transmits it to the analysis module 402. The threshold module 403 simulates the simulated colorimetric data Un generated by the colorimeter 110 when the platelets in the collection bag are in a uniform state, and integrates the simulated colorimetric data Un to form a first threshold range. The threshold module 403 simulates the simulated colorimetric data Uv generated by the colorimeter 110 in a certain region when small clumps of platelets appear in the collection bag, and integrates the simulated colorimetric data Uv to form a second threshold range. The threshold module 403 transmits the first threshold range and the second threshold range to the analysis module 402.

[0043] The analysis module 402 compares the real-time colorimetric data U with the first threshold range and the second threshold range, and sends the comparison result to the control module 404. When the real-time colorimetric data U is not within the first threshold range, the control module 404 determines that the platelets in the collection bag are in a non-uniform distribution state, and the control module 404 issues a first decision to the execution module 405. When the real-time colorimetric data U is within the second threshold range, the control module 404 determines that small platelet clumps appear in the area.

[0044] The execution module 405 receives a quantitative current input from the first decision control main mechanism 1, and the main mechanism 1 drives the platelets in the collection bag to continuously shake. The execution module 405 receives a second decision control adjustment mechanism 3 to shake the small clumps of platelets in the collection bag.

[0045] In this embodiment, when the real-time colorimetric data is within the first threshold range, it can be determined that the platelets in the collection bag are in a uniform state. The control module 404 sends a third decision to the execution module 405. The execution module 405 receives the third decision and feeds it back to the DPS processor. The DPS processor controls the display on the surface of the control device 102 to issue a reminder, reminding the staff that the platelets in the collection bag are in a uniform distribution state.

[0046] The specific workflow of this invention is as follows:

[0047] Step 1: The collection bag containing platelets is placed on the surface of the placement plate 202. The first electro-hydraulic column 204 inputs current to drive the first slide plate 205, the auxiliary limiting frame 206 and the limiting plate 207 to contact the surface of the collection bag. The limiting plate 207 drives the spring 208 to be in a compressed state, generating spring force to drive the limiting plate 207 to the position of the collection bag, thereby achieving the function of limiting and fixing the collection bag.

[0048] Step 2: When the platelet collection bag is positioned within the inner wall of the limiting mechanism 2, the servo motor 108 inputs current to drive the transmission rod 107 to move the support plate 109, support frame 105, and limiting mechanism 2 to sway left and right, thereby driving the platelets in the collection bag to be shaken evenly. During the shaking process, the lighting device 104 inputs current to assist the colorimeter 110 in collecting colorimetric data U in each area of ​​the collection bag. The colorimetric data U collected by the colorimeter 110 is transmitted to the control system 4. The control system 4 determines whether the platelets in the collection bag are in a shaking state based on the change in colorimetric data U.

[0049] Step 3: When the control system 4 determines that small platelet clumps appear in a certain area of ​​the collection bag, the control system 4 controls the micro motor 302 to input current, driving the transmission screw 304 to start rotating. The transmission screw 304, in the optional state, drives the slider 303 and the main hollow plate 301 to move to the designated position. At the same time, the second electro-hydraulic column 305 and the electric lifting device input a quantitative current, driving the two sets of rubber plates 307 to move to the vicinity of the small platelet clumps. The two sets of rubber plates 307 apply a slight external force to the small platelet clumps to disperse them evenly, avoiding any impact of the small platelet clumps on the blood test data.
