Description

Technical Field

[0001] This utility model relates to the field of whole blood separation technology, and in particular to a fully automatic blood separation device. Background Technology

[0002] A fully automated blood separator is a medical device that uses automation technology to precisely separate blood components. It is widely used in blood banks, hospital transfusion departments, and single-donor plasma collection stations. Its core principle is to automatically separate blood components (such as red blood cells, plasma, and platelets) through centrifugal force and density differences, and then transfer the target components to daughter bags by squeezing the mother bag, achieving efficient, safe, and accurate collection. It is widely used in blood banks and medical institutions.

[0003] Patent CN207532841U discloses a fully automated blood component separator using a color sensor. The separator includes a rear body, a front body, and a clamping plate between them. The rear body has several clamping devices, each containing a color sensor. During the separation of plasma and red blood cells, the outlet pipe of the mother bag connects to the daughter bag after passing through the clamping devices. The color sensor in the clamping device monitors the color of the liquid in the pipe in real time. Since plasma is pale yellow and red blood cells are dark red, the color sensor can detect red blood cells mixed in with plasma when they pass through the clamping devices based on their color. This invention uses a color sensor, requiring only color calibration before use. It is unaffected by external light during operation, resulting in more accurate detection results.

[0004] The inventors have discovered at least the following problems in the prior art:

[0005] The existing fully automatic blood separation device requires squeezing the blood in the mother bag using a squeezing plate. As a result, some blood cannot be squeezed out when squeezing the mother bag, and therefore cannot be separated, leading to waste.

[0006] Therefore, this solution provides a fully automated blood separation device to solve the above problems. Utility Model Content

[0007] The purpose of this invention is to provide a fully automatic blood separation device to solve the problems existing in the prior art.

[0008] To solve the above-mentioned technical problems, the basic technical solution proposed by this utility model is as follows:

[0009] A fully automatic blood separation device includes a separation mechanism. The separation mechanism has a linkage pressure plate mechanism and a drive plate mechanism disposed inside it. The linkage pressure plate mechanism is located on one side of the drive plate mechanism. The linkage pressure plate mechanism includes an arc-shaped pressure plate and V-shaped protrusions evenly distributed on one side of the arc-shaped pressure plate. The drive plate mechanism includes a drive plate, linkage sliders slidably connected to both ends of the drive plate, and a connecting rod fixedly connected to the other end of the drive plate. One end of the connecting rod is connected to the separation mechanism, and a limit component is disposed above the other end. The limit component includes a limit receiving block, a transmission inclined block, and an integrated limit inclined block and linkage inclined block.

[0010] Preferably, the upper side of the arc-shaped pressure plate is rotatably connected to a drive plate, the lower side of the arc-shaped pressure plate is rotatably connected to a connecting rod, and the other end of the connecting rod is rotatably connected to a linkage slider.

[0011] Preferably, the cross-section of the V-shaped protrusion is an obtuse triangle.

[0012] Preferably, the linkage slider is provided with a resistance spring and a hanging plate at the top and bottom respectively, the hanging plate is fixedly connected to the linkage slider, and the hanging plate fits into the limiting inclined block.

[0013] Preferably, a trigger slider is slidably connected above the connecting rod, a stop rod is fixedly connected to one side of the trigger slider, a return spring is provided at the sliding connection of the trigger slider, the stop rod cooperates with the bottom end of the transmission inclined block, and the upper end of the transmission inclined block cooperates with the linkage inclined block.

[0014] Preferably, a groove is provided on one side of the limiting receiving block, and a limiting groove and a slot are provided on the adjacent side of the limiting receiving block. An elastic element is provided inside the slot, and the elastic element is located at one end of the limiting inclined block and the linkage inclined block.

[0015] Preferably, both the limiting wedge and the linkage wedge are inserted into the inside of the slot, and part of the transmission wedge is slidably connected inside the limiting groove.

[0016] The beneficial effects of this utility model are:

[0017] I. This utility model utilizes the coordinated operation of a linkage pressure plate mechanism and a drive plate mechanism. The drive plate mechanism triggers the linkage between the slider, the stop rod, and the transmission inclined block. At the end of the compression, the limiting inclined block automatically releases the locking of the hanging plate, allowing the arc-shaped pressure plate to rotate with the upper end of the drive plate as the fulcrum. This achieves gradual compression of the mother bag from bottom to top, reducing blood waste.

[0018] Second, through the cooperation of the linkage pressure plate mechanism and the drive plate mechanism, this utility model, in the process of gradually squeezing the mother bag from bottom to top, combined with the V-shaped protrusion obtuse-angled triangular cross section design (soft rubber material), can deform and fit the side wall of the mother bag during the squeezing process, guiding the blood to flow to the middle and the outlet, avoiding local residue.

[0029] Please refer to the following. Figures 1 to 5 As shown, the technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0030] It should be noted that, in the embodiments of this utility model, the directions shown in the accompanying drawings shall prevail, such as front and back. Figure 1 For the sake of accuracy, the specific details should be as follows: Figure 1 The left side is the front. Figure 1 The right side is the rear; at the same time, as Figure 2As shown, the horizontal direction is roughly defined as left and right, and the vertical direction is defined as up and down. If a specific orientation changes, the directional indication will also change accordingly.

[0031] This utility model provides a fully automatic blood separation device, including a separation mechanism 1, a linkage pressure plate mechanism 2 and a drive plate mechanism 3 arranged inside the separation mechanism 1, and the linkage pressure plate mechanism 2 is located on one side of the drive plate mechanism 3;

[0032] The linkage pressure plate mechanism 2 includes an arc-shaped pressure plate 21 and V-shaped protrusions 22 that are evenly distributed and fixedly connected to one side of the arc-shaped pressure plate 21;

[0033] The drive plate mechanism 3 includes a drive plate 31, a linkage slider 32 slidably connected to both ends of the drive plate 31, and a connecting rod 35 fixedly connected to the other end of the drive plate 31. One end of the connecting rod 35 is connected to the separation mechanism 1, and a limit component 39 is provided above the other end.

[0034] The limiting component 39 includes a limiting receiving block 391, a transmission inclined block 398, and an integrated limiting inclined block 395 and a linkage inclined block 396.

[0035] The separation mechanism 1 is a fully automatic blood component separator in the prior art.

[0036] In a further embodiment, the upper side of the arc-shaped pressure plate 21 is rotatably connected to the drive plate 31, and the lower side of the arc-shaped pressure plate 21 is rotatably connected to the connecting rod 23, and the other end of the connecting rod 23 is rotatably connected to the linkage slider 32.

[0037] In this embodiment, the side of the arc-shaped pressure plate 21 near the drive plate 31 and the drive plate 31 both have ear plates, which are rotatably connected to each other; the connecting rod 23 is used for transmission so that the linkage slider 32 can be pushed upward after it is unlocked.

[0038] In a further embodiment, the cross-section of the V-shaped protrusion 22 is an obtuse triangle.

[0039] In this embodiment, the V-shaped protrusion 22 is an inverted V-shape made of soft rubber, which will deform when the mother bag is squeezed to cooperate with the side wall of the separation mechanism 1 and guide the blood in the mother bag.

[0040] In a further embodiment, a resistance spring 33 and a hanging plate 34 are respectively provided above and below the linkage slider 32. The hanging plate 34 is fixedly connected to the linkage slider 32 and engages with the limiting inclined block 395.

[0041] In this embodiment, the two ends of the drive plate 31 are provided with grooves at the linkage slider 32, so that the linkage slider 32 can slide, and the resistance spring 33 is displaced in the groove; the resistance of the resistance spring 33 is greater than that of the reset spring 38, so that the linkage slider 32 can always be pushed down, so as to maintain the compression strength on the mother bag when the lower side of the arc-shaped pressure plate 21 is attached to the side wall of the separation mechanism 1.

[0042] In a further embodiment, a trigger slider 36 is slidably connected above the connecting rod 35, a stop rod 37 is fixedly connected to one side of the trigger slider 36, a reset spring 38 is provided at the sliding connection of the trigger slider 36, the stop rod 37 cooperates with the bottom end of the transmission inclined block 398, and the upper end of the transmission inclined block 398 cooperates with the linkage inclined block 396.

[0043] In this embodiment, the bottom of the trigger slider 36 is slidably connected to the top of the connecting rod 35, and the connecting rod 35 is also provided with a corresponding groove. The reset spring 38 is located in the groove and is used to reset the trigger slider 36 after the extrusion is completed and the drive plate mechanism 3 is reset. During the displacement process with the connecting rod 35, the trigger slider 36 contacts the inner wall of the separation mechanism 1 before the lower side of the arc-shaped pressure plate 21, thereby releasing the linkage slider 32 first.

[0044] In a further embodiment, a groove 392 is provided on one side of the limiting receiving block 391, and a limiting groove 394 and a slot 393 are provided on the adjacent side of the limiting receiving block 391. An elastic element 397 is provided inside the slot 393, and the elastic element 397 is located at one end of the limiting inclined block 395 and the linkage inclined block 396.

[0045] In this embodiment, the tangential directions of the limiting inclined block 395 and the linkage inclined block 396 are opposite.

[0046] In a further embodiment, both the limiting wedge block 395 and the linkage wedge block 396 are inserted into the inside of the slot 393, and part of the transmission wedge block 398 is slidably connected inside the limiting groove 394.

[0047] In this embodiment, the groove 392 is used to allow the push rod 37 to be inserted after the push rod 37 has completely pushed the transmission inclined block 398 upward.

[0048] The working principle of this utility model is as follows:

[0049] When the mother bag needs to be squeezed, it can be hung on one side of the linkage pressure plate mechanism 2. Then, the drive device inside the separation mechanism 1 pulls the connecting rod 35 to make the entire drive plate mechanism 3 and the linkage pressure plate mechanism 2 displace and squeeze the mother bag. During the squeezing process, the lower end of one side of the arc-shaped pressure plate 21 will squeeze the mother bag first. After squeezing for a certain period of time, the side of the trigger slider 36 will contact the separation mechanism 1, so that the abutment 37 will contact the transmission inclined block 398 and make the transmission inclined block 398 move upward. This causes the linkage inclined block 396 and the limit inclined block 395 to retract into the slot 393. At this time, the limit inclined block 395 will no longer restrict the hanging plate 34. At this time, the lower side of the arc-shaped pressure plate 21 also contacts the separation mechanism 1, and the linkage slider 32 moves upward through the connecting rod 23, so that the arc-shaped pressure plate 21 rotates with the upper end as the center. At this time, the arc-shaped pressure plate 21 will gradually squeeze the mother bag from bottom to top, thereby avoiding some blood residue and avoiding waste.

[0050] When the arc-shaped pressure plate 21 squeezes the mother bag from bottom to top, the blood being squeezed inside the mother bag will move upward and towards the middle simultaneously due to the guidance of the V-shaped protrusion 22. Therefore, it can be concentrated at the liquid outlet of the mother bag, thereby accelerating the flow rate and improving the squeezing efficiency.

[0051] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
