AI Technical Summary
During the existing blood separation process, the separation clamp operation needs to be manually performed, which can easily lead to the fall of plasma bags and the separation efficiency. Due to the hard clamp, improper operation is prone to the incorrect red blood cells entering the catheter, resulting in low separation efficiency.
An auxiliary plate for blood plasma clamp is designed, using a soft foam motherboard with a width and a narrow upper part, equipped with elastic straps, protrusions and grooves to enhance friction and cushioning to prevent the plasma bag from slipping and squeezing.
It improves the separation efficiency between plasma and red blood cells, reduces the difficulty of operation, prevents red blood cells from entering the catheter by mistake, avoids damage to plasma bags, and enhances the clarity of separation.

Abstract
Description
Technical Field
[0001] The utility model belongs to the field of blood separation auxiliary equipment, in particular to an auxiliary plate for a blood plasma separation clamp. Background Art
[0002] Plasma separation is the process of separating plasma from red blood cells in the blood. Usually, centrifugal separation is performed using a centrifugal device based on the principle that each component in the blood has a different specific gravity. The separated plasma is at the top of the plasma bag, while the red blood cell serum is at the top of the plasma bag. The plasma in the plasma bag must be squeezed out by a separator clamp to achieve a thorough separation of the plasma and the red blood cell serum. A separator clamp is required in this step. Existing separator clamps are mostly manually operated, and the clamps are smooth hard plates. During operation, the plasma bag is easy to fall off, and due to manual operation, the clarity of the separation depends entirely on experience. Existing separator clamps with hard clamps have linear separation. At the contact line between plasma and red blood cell serum, the operator needs to be particularly careful, otherwise it is easy for red blood cells to enter the catheter or separation bag by mistake, resulting in low separation efficiency. Therefore, it is necessary to develop an auxiliary device to solve the above problems. Utility Model Content
[0003] In view of the above technical problems, the utility model provides an auxiliary plate for a blood plasma separation clamp.
[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: an auxiliary plate for a blood plasma clamp, including a main board, the width of the bottom of the main board is greater than the width of the top, the back of the main board is connected with a strap, the front has several protrusions, and the back of the main board is provided with a groove.
[0005] Furthermore, the main board is made of soft foam material.
[0006] Furthermore, the strap is made of elastic material.
[0007] Compared with the prior art, the utility model has the following advantages:
[0008] 1. The utility model is provided with a main board which is wider at the bottom and narrower at the top. When separating plasma, the lower part is wider so that the upper plasma can be squeezed out quickly. When it reaches the boundary between plasma and red blood cell plasma, the main board becomes narrower, which can slow down the speed of separation and make the separation clearer. A strap is provided to prevent the main board from slipping, a protrusion is provided to increase the friction of the surface so that the plasma bag is not easy to slip, and a groove is provided to play a buffering role to prevent the staff from squeezing the plasma bag due to excessive force.
[0009] 2. The material of the utility model is soft foam to avoid squeezing the plasma bag. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 3 It is a schematic diagram of the bottom structure of the utility model.
[0013] Figure 4 It is a schematic diagram of the slurry separation clamp structure.
[0014] Among them: 1. main board, 2. binding strap, 3. protrusion, 4. groove, a. stand, b. fixed splint, c. movable splint, d. handle. DETAILED DESCRIPTION
[0015] The utility model will be further described below in conjunction with the accompanying drawings.
[0016] like Figure 1 , Figure 2 , Figure 3 The auxiliary plate for a blood plasma clamp shown in the figure comprises a main board 1, the width of the bottom of the main board 1 is greater than the width of the top, a strap 2 is connected to the back of the main board 1, a plurality of protrusions 3 are arranged on the front, and a groove 4 is opened on the back of the main board 1.
[0017] In order to prevent the plasma bag from being squeezed, the main board 1 is made of soft foam material.
[0018] In order to tie more firmly, the strap 2 is made of elastic material.
[0019] The specific working process of the utility model is as follows:
[0020] When working, you need to cooperate with Figure 4 The pulp separator clamp shown.
[0021] The main board 1 is bound to the fixed splint b by the strap 2, the plasma bag is placed between the fixed splint b and the movable splint c, and the plasma collection bag is connected. The movable splint c is squeezed by the handle d. At this time, the wider lower side of the main board 1 can increase the separation speed of the plasma. When the plasma and red blood cell serum are separated, the plasma bag has contacted the middle position of the main board 1. At this time, the plasma separation speed slows down. When the staff separates, the handle d can be moved to a large extent, which reduces the control difficulty and improves the separation efficiency. In this process, the protrusion 3 increases the friction force to prevent the plasma bag from falling, and the groove 4 plays a buffering role to prevent the staff from squeezing the plasma bag too hard during separation.
