[0025] As shown in Figure 1 - Figure 3 The present embodiment provides a technical solution: a plasma protein separation liquid adding device convenient to maintain, comprising a liquid adding rod body 1, the outer surface of the liquid adding rod body 1 is fixedly connected with a mounting frame 11, one end of the liquid adding rod body 1 is provided with a buffer solution tank 12, the side surface of the mounting frame 11 is provided with a clamping assembly 2;

[0026] The clamping assembly 2 comprises a limiting sleeve 21, the inner wall of the limiting sleeve 21 is fixedly connected with a fixed ring 22, the side surface of the fixed ring 22 is fixedly connected with a first elastic sheet 23, the end of the first elastic sheet 23 away from the fixed ring 22 is fixedly connected with a sliding ring 24, the side surface of the limiting sleeve 21 is fixedly connected with a sleeve 25, the bottom of the sleeve 25 is fixedly connected with a second elastic sheet 26, the bottom of the second elastic sheet 26 is fixedly connected with a fixed plate 27, the liquid adding rod body 1 is made of stainless steel material, one end of the liquid adding rod body 1 penetrates and extends to the inner cavity of the buffer solution storage tank 12, the side surface of the buffer solution storage tank 12 is provided with a micro pump, and the top of one end of the liquid adding rod body 1 is provided with an adjusting valve. In use, first, the liquid adding rod body 1 is pushed into the inner cavity of the limiting sleeve 21, and when the liquid adding rod body 1 moves, the mounting bracket 11 and the limiting groove 29 cooperate, so that the movement track of the liquid adding rod body 1 can be limited, avoiding that the position of the liquid adding rod body 1 deviates in the splicing process, causing a gap in the connection, and then causing the problem of leakage. When the liquid adding rod body 1 moves to a certain position, the side surface of the mounting bracket 11 contacts the side surface of the sliding ring 24, so that the first elastic sheet 23 is compressed. At this time, the liquid adding rod body 1 is rotated clockwise, and when the liquid adding rod body 1 is rotated to a certain position, the first elastic sheet 23 releases stress, so that the mounting bracket 11 and the limiting sleeve 21 are clamped, and then the effect of rapid splicing can be realized. By arranging the fixed ring 22, the first elastic sheet 23 and the sliding ring 24 can be supported. After splicing is completed, the buffer solution is injected into the inner cavity of the buffer solution storage tank 12, and the micro pump is started, so that the buffer solution flows into the inner cavity of the liquid adding rod body 1, and then the effect of separating the plasma protein can be realized. Similarly, when cleaning is needed, first, the liquid adding rod body 1 is pushed into the inner cavity of the limiting sleeve 21, and when the liquid adding rod body 1 moves to a certain position, the liquid adding rod body 1 is rotated counterclockwise, so that the liquid adding rod body 1 is segmented and taken out, and then rinsing and nursing work is carried out, effectively improving work efficiency and maintenance effect, avoiding the problem that the separation effect is affected due to that the gap in the channel inner cavity is not cleaned.

[0027] Further, as Figure 2 Figure 4 ​As shown: one end of the sleeve 25 is provided with the partition assembly 3, the partition assembly 3 includes the protective shell 31, the inner cavity of the protective shell 31 is fixedly connected with the limiting frame 32, the side surface of the limiting frame 32 is provided with the supporting seat 33, the side surface of the supporting seat 33 is provided with the flexible sealing plate 36, the side surface of the supporting seat 33 is provided with the guide groove 34, the flexible sealing plate 36 is fixedly connected with the slide rod 35, one end of the slide rod 35 extends to the inner cavity of the guide groove 34, one end of the slide rod 35 is slidably connected with the inner cavity of the guide groove 34, the inner cavity of the limiting frame 32 is provided with the embedded pipe 37, the liquid adding rod body 1 and the protective shell 31 are fixed by buckling, when cleaning is needed, the liquid adding rod body 1 is counterclockwise rotated, so that the protective shell 31 drives the limiting frame 32 to rotate counterclockwise, when the limiting frame 32 rotates counterclockwise, the limiting frame 32 drives the slide rod 35 to move along the inner cavity of the flexible sealing plate 36, so that the flexible sealing plate 36 moves to the middle part of the limiting frame 32, at this time, the liquid adding rod body 1 is pulled outward, so that the embedded pipe 37 is separated from the inner cavity of the limiting frame 32, thereby achieving the effect of partitioning the middle part of the limiting frame 32 by the flexible sealing plate 36, avoiding that the buffer solution in the inner cavity of the buffer solution storage tank 12 contacts with air for a long time when the inner cavity of the liquid adding rod body 1 is cleaned, so that dust and other impurities enter the inner cavity of the buffer solution storage tank 12, thereby affecting the separation effect of the plasma protein.

[0028] In use, since the flow demand of the buffer solution is different when the plasma protein is separated, the stress of the connecting part of the liquid adding rod body 1 increases when the flow changes, causing loosening, such as Figure 3 As shown: in this scheme, the top of the sleeve 25 is provided with the groove 28, the top of the limiting sleeve 21 is provided with the limiting groove 29, the outer surface of one end of the liquid adding rod body 1 is provided with the sealing ball 210, during splicing the liquid adding rod body 1, when the mounting frame 11 rotates clockwise, the top of the sealing ball 210 contacts with the inner wall of the fixed plate 27, so that the second elastic sheet 26 is compressed, at this time, the mounting frame 11 continues to move, so that the sealing ball 210 enters the inner cavity of the groove 28, thereby achieving the effect of secondary sealing and fixing the connecting part, avoiding the problem that the impact force of the buffer solution causes the connecting part to shake when the pressure increases due to the flow change, effectively improving the stability.

[0029] Working principle:

[0030] As shown: Figures 1-4 As shown:

[0031] In use: first push the liquid adding rod body 1 along the inner cavity of the limiting sleeve 21, when the liquid adding rod body 1 moves to a certain position, the side surface of the mounting frame 11 contacts with the side surface of the sliding ring 24, so that the first elastic sheet 23 is compressed, at this time, rotate the liquid adding rod body 1 clockwise, when the liquid adding rod body 1 rotates to a certain position, the first elastic sheet 23 releases stress, so that the mounting frame 11 is clamped with the limiting sleeve 21, at the same time, the sealing ball 210 enters the inner cavity of the groove 28, so that the connection is sealed and fixed again, after splicing is completed, inject the buffer solution into the inner cavity of the buffer solution storage groove 12, start the micro pump, so that the buffer solution flows into the inner cavity of the liquid adding rod body 1, thereby the effect of separating the plasma protein is realized, similarly, when cleaning is needed, first push the liquid adding rod body 1 into the inner cavity of the limiting sleeve 21, when the liquid adding rod body 1 moves to a certain position, rotate the liquid adding rod body 1 counterclockwise, so that the liquid adding rod body 1 is segmented and taken out, then is washed and nursed respectively, at the same time, when the liquid adding rod body 1 rotates counterclockwise, the limiting frame 32 is driven to rotate counterclockwise by the protection shell 31, when the limiting frame 32 rotates counterclockwise, the sliding rod 35 is driven to move along the inner cavity of the flexible sealing plate 36 by the limiting frame 32, so that the flexible sealing plate 36 moves to the middle part of the limiting frame 32, at this time, pull the liquid adding rod body 1 outward, so that the embedded pipe 37 is separated from the inner cavity of the limiting frame 32, thereby the effect that the middle part of the limiting frame 32 is separated by the flexible sealing plate 36 is realized.
