AI Technical Summary
The existing plasma separation clamps do not clamp evenly when the blood bag is not upright, which can cause red blood cells to accidentally enter the catheter or the plasma bag to slip off, resulting in incomplete separation. In addition, the surface of the clamps is smooth and easy to slip off.
An auxiliary plate for blood separation clamping was designed, comprising a clamping component and a driving component. The clamping component clamps the corners of the blood bag and uses rubber blocks to increase friction, while the driving component flips the clamping plate and engages gears to ensure uniform compression, thereby achieving complete separation of the blood bag in a vertical position.
This method achieves stable clamping and uniform compression of blood bags, reduces the mixing of red blood cells and plasma, and improves the separation effect.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of blood separation technology, and in particular relates to an auxiliary plate for blood plasma separation clamp. Background Technology
[0002] Plasma separation is the process of separating blood plasma from red blood cells. It usually starts with centrifugation, which is performed based on the principle that the different components in the blood have different specific gravities. After separation, the plasma is at the top of the plasma bag, while the red blood cell plasma is at the top. The plasma is then squeezed out of the plasma bag by a separator to achieve complete separation of plasma and red blood cell plasma.
[0003] In the current process of squeezing and separating blood bags using a plasma separation clamp, because the blood bag is not in a vertical position and the clamp cannot clamp the two sides of the blood bag to the same degree, red blood cells are prone to accidentally enter the catheter or separation bag at the contact line between plasma and red blood cell plasma. This results in incomplete blood separation and easy mixing of blood. Secondly, during the squeezing process, the smooth surface of the clamp makes it easy for the plasma bag to slip off the clamp. In view of this, we propose an auxiliary plate for blood plasma separation clamps. Utility Model Content
[0004] The purpose of this invention is to provide an auxiliary plate for blood plasma separation clamps to solve the problems mentioned in the background art.
[0005] In view of this, the present invention provides an auxiliary plate for blood plasma separation clamp, including a mounting base, a mounting frame fixedly mounted on the rear outer wall of the mounting base, a mounting plate fixedly mounted on the front side of the top of the mounting base, and two second connecting shafts rotatably mounted on the rear outer wall of the mounting plate, with clamping plates fixedly mounted on the outer walls of the two second connecting shafts.
[0006] Multiple sets of clamping assemblies are mounted on a mounting frame and used to clamp blood bags;
[0007] A drive assembly, which is mounted on a mounting plate and is used to drive the two clamping plates to flip.
[0008] In the above technical solution, the clamping component further includes:
[0009] Two clamping blocks are disposed opposite each other on the inner side of the top of the mounting frame. A bidirectional threaded rod is threaded through and threaded between the two clamping blocks. Both ends of the bidirectional threaded rod are rotatably connected to the mounting frame. A knob is fixedly installed at one end of the bidirectional threaded rod. Rubber blocks are fixedly installed on adjacent sides of the two clamping blocks.
[0010] In the above technical solution, the driving component further includes:
[0011] Two second adapters are fixedly installed on opposite sides of two clamps. A first connecting shaft is rotatably installed on the inner wall of each of the two second adapters. Each of the two first connecting shafts passes through the mounting plate. A first adapter is rotatably installed on the other end of each of the two first connecting shafts. An electric push rod is fixedly installed between the two first adapters.
[0012] In the above technical solution, a bearing seat is further fixedly installed on the rear side of the top of the mounting base, and one end of each of the two second connecting shafts passes through and is rotatably connected to the bearing seat.
[0013] In the above technical solution, furthermore, gears are fixedly installed at the other ends of the two second connecting shafts, and the two gears are meshed together.
[0014] In the above technical solution, two guide rods are slidably installed through each of the clamping blocks, and both ends of the multiple sets of guide rods are fixedly connected to the mounting frame.
[0015] In the above technical solution, further, two oppositely arranged arc-shaped holes are opened on the rear side of the mounting plate, and the two first connecting shafts pass through the two arc-shaped holes respectively.
[0016] The beneficial effects of this utility model are:
[0017] 1. The blood collection clamp uses an auxiliary plate, which clamps the two upper corners of the blood bag with two sets of clamping components to fix it in place. During the clamping process, the corners of the blood bag can be inserted into the gap between the two clamping blocks. Then, by rotating the knob, the bidirectional threaded rod drives the two clamping blocks to move closer to each other until the two rubber blocks clamp the blood bag tightly. The rubber blocks can increase the friction and prevent the blood bag from falling off.
[0018] 2. The blood separation clamp uses an auxiliary plate. After the blood bag is clamped, the drive component can be controlled to move the two clamping plates closer together and squeeze the blood bag to facilitate separation. The clamping component holds the blood bag in a suspended manner, keeping the blood bag in a vertical position. Furthermore, during the flipping process of the two clamping plates, the meshing of the two gears ensures that the two clamping plates flip at the same angle, resulting in equal pressure on both sides of the blood bag, making the separation more thorough and reducing the amount of impurities.

[0033] Multiple clamping assemblies are mounted on the mounting frame 3 and are used to clamp blood bags;
[0034] The drive assembly is mounted on the mounting plate 4 and is used to drive the two clamping plates 2 to flip.
[0035] After the blood bag is clamped, the electric push rod 16 can be controlled to retract, so that the two clamps 2 come together and squeeze the blood bag, thereby assisting in the separation of plasma.
[0036] Example 2:
[0037] This embodiment provides an auxiliary plate for blood plasma separation clamping. In addition to the technical solutions of the above embodiments, it also has the following technical features: the clamping assembly includes:

Rubber blocks 14 are fixedly installed on adjacent sides of the two clamping blocks 8.
[0039] During the process of clamping the corners of the blood bag, the corners of the blood bag can be inserted into the gap between the two clamping blocks 8. Then, by rotating the knob 12, the bidirectional threaded rod 11 drives the two clamping blocks 8 to move closer to each other until the two rubber blocks 14 clamp the blood bag tightly. The rubber blocks 14 can increase the friction and prevent the blood bag from falling off.
[0040] Example 3:
[0041] This embodiment provides an auxiliary plate for blood plasma separation clamps. In addition to the technical solutions of the above embodiments, it also has the following technical features, and the driving component includes:
[0042] Two second adapters 10 are fixedly installed on opposite sides of the two clamping plates 2.

A first adapter 5 is rotatably installed at the other end of each of the two first connecting shafts 15. An electric push rod 16 is fixedly installed between the two first adapters 5.
[0043] In this process, by controlling the extension of the electric push rod 16, the electric push rod 16 pushes the two first adapters 5 away from each other. At the same time, the two first connecting shafts 15 will drive the two second adapters 10 to separate, and the two clamps 2 will rotate to both sides with the axis of rotation of the two second connecting shafts 17 as the center of rotation.
[0044] Example 4:
[0045] This embodiment provides an auxiliary plate for blood plasma separation clamps. In addition to the technical solutions of the above embodiments, it also has the following technical features: a bearing seat 9 is fixedly installed on the rear side of the top of the mounting base 1, and one end of each of the two second connecting shafts 17 passes through and is rotatably connected to the bearing seat 9.
[0046] Among them, the bearing seat 9 serves to limit and support the second connecting shaft 17.

In addition to the technical solutions of the above embodiments, it also has the following technical features: the other ends of the two second connecting shafts 17 are fixedly installed with gears 7, and the two gears 7 are meshed and connected.
[0049] During the flipping process of the two clamping plates 2, the meshing action of the two gears 7 ensures that the two clamping plates 2 flip at the same angle.
[0050] Example 6:
[0051] This embodiment provides an auxiliary plate for blood plasma separation clamps. In addition to the technical solutions of the above embodiments, it also has the following technical features: two guide rods 13 are slidably installed through each of the clamping blocks 8, and both ends of the multiple sets of guide rods 13 are fixedly connected to the mounting frame 3.
[0052] As the two clamping blocks 8 approach each other, they slide along the guide rod 13. The stability of the clamping blocks 8 can be improved through the cooperation between the two guide rods 13 and the clamping blocks 8.
[0053] Example 7:
[0054] This embodiment provides an auxiliary plate for blood plasma separation clamps. In addition to the technical solutions of the above embodiments, it also has the following technical features: two opposing arc-shaped holes 6 are opened on the rear side of the mounting plate 4, and two first connecting shafts 15 pass through the two arc-shaped holes 6 respectively.
[0055] During the flipping of the two clamping plates 2, the two first connecting shafts 15 move within the two arc-shaped holes 6 respectively, and the spacing between the arc-shaped holes 6 is the same as the diameter of the first connecting shafts 15.
[0056] Working principle: First, by controlling the extension of the electric push rod 16, the electric push rod 16 pushes the two first adapters 5 away from each other. At the same time, the two first connecting shafts 15 will drive the two second adapters 10 to separate. Simultaneously, the two clamping plates 2 will rotate to both sides around the axis of rotation of the two second connecting shafts 17. During the rotation of the two clamping plates 2, the meshing action of the two gears 7 makes the two clamping plates 2 rotate at the same angle. When the two clamping plates 2 open, the two sets of clamping components can then clamp the two upper corners of the blood bag respectively, thereby achieving fixation. During the clamping of the corners of the blood bag, the corners of the blood bag can be inserted into the gap between the two clamping blocks 8, and then... Rotating knob 12 causes the bidirectional threaded rod 11 to drive the two clamping blocks 8 to move closer together until the two rubber blocks 14 clamp the blood bag. The rubber blocks 14 can increase friction and prevent the blood bag from falling off. As the two clamping blocks 8 move closer together, they will slide along the guide rod 13. The cooperation between the two guide rods 13 and the clamping blocks 8 can improve the stability of the clamping blocks 8. When the blood bags are of different sizes, clamping components with the same spacing can be selected according to the distance between the two sides of the blood bag. During the flipping of the two clamping plates 2, the two first connecting shafts 15 move in the two arc-shaped holes 6 respectively. After the blood bag is clamped, the electric push rod 16 can be controlled to retract, so that the two clamping plates 2 move closer together and squeeze the blood bag, thereby assisting in the separation of plasma.
