Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the following further describes the technical solution of the present invention with reference to the drawings and the embodiments.

Referring to fig. 1-4, an automatic pulp separating clamp applying absorbance detection includes a pulp separating clamp 1 having a base 11, a back plate 12 vertically disposed on one side of the base 11, a pressing plate 13 hinged to the base 11 on one side of the back plate 12, and a driving rod 14 horizontally hinged to the bottom of the outer side of the pressing plate 13 for driving the pressing plate 13 to approach or leave the back plate 12. Specifically, the base 11 is further provided with a limit hook 15 for limiting the driving rod 14, and the limit hook 15 is used for limiting the driving rod 14 in the limit hook 15 (as shown in fig. 1) when the slurry separation clamp 1 is not used, so as to avoid the problem that the slurry separation clamp 1 is damaged by the swinging of the pressing plate 13 after being collided with the backboard in the displacement or transfer process.

The operation of the slurry separation clamp 1 is as follows: the plasma bag 2 after separating the plasma and the red blood cell serous fluid is placed between the pressing plate 13 and the back plate 12, the driving rod 14 is horizontally rotated to be separated from the limit of the limit hook 15, then the driving rod 14 is driven upwards, and simultaneously the pressing plate 13 is driven to extrude the plasma bag 2 towards the direction of the back plate 12, under the joint extrusion action of the pressing plate 13 and the back plate 12, the plasma at the upper part in the plasma bag 2 gradually flows out to an empty collection bag (22 in figure 4) through the conduit 21 at the top end of the plasma bag 2, and the plasma in the plasma bag 2 is continuously and completely separated from the red blood cell serous fluid at the bottom through the continuous extrusion of the pressing plate 13, so that the plasma separation operation is realized.

In order to solve the problem that the height of the red blood cell serum in the serum separating clamp 1 cannot be accurately detected when the serum separating clamp 1 is operated, so that an operator cannot clamp the red blood cell serum timely and the red blood cell serum is easy to enter a conduit or a separation bag by mistake, as shown in fig. 1, an absorbance detection device is arranged on the back plate 12, a closed structure for driving the conduit 21 of the plasma bag 2 clamped between the back plate 12 and the pressing plate 13 to block and circulate is further arranged on the base 11, and a control device (not shown in the figure) for electrically connecting the absorbance detection device with the closed structure. The automatic operation principle is as follows: the blood plasma bag 2 to be separated is clamped between the back plate 12 and the pressing plate 13, the top end of the blood plasma bag 2 corresponds to the absorbance detection device, the guide pipe 21 is placed in the sealing device, the blood plasma bag 2 is extruded and continuously separated by driving the pressing plate 13, when the liquid level at the top end of the red blood cell serum (and the segmentation liquid level of the blood plasma) at the bottom reaches the top end of the blood plasma bag 2, the blood plasma is completely extruded and separated and flows out through the guide pipe, at the moment, the absorbance detection device detects the top liquid level of the red blood cell serum, so that the absorbance value is changed and fed back to the control device, the control device immediately drives the sealing structure to obstruct the circulation of the guide pipe 21, the problem that the red blood cell serum flows into the blood plasma collection bag in an extruded state to cause incomplete separation is avoided, and accurate automatic plasma separation operation can be further realized.

Preferably, the control device is further connected with an alarm, and the alarm is driven to sound in the feedback process of the absorbance detection device so as to prompt an operator to stop squeezing the plasma bag 2 and avoid the problem that the red blood cell serum is squeezed out. Under the action of the alarm, an operator can simultaneously operate two or even more slurry separating clamps so as to improve the separation efficiency.

Specifically, as shown in fig. 1, the absorbance detecting device is an absorbance detector 3 disposed on an outer side wall of the back plate 12, and the absorbance detector 3 has a horizontal detecting probe 31 extending out of an inner wall of the back plate 12 or flush with the inner wall of the back plate 12. Before placing the separation of plasma bag 2, adjust the contained angle of clamp plate 13 and backplate 12 according to its size and specification to make 2 tops of plasma bag highly correspond with horizontal detection probe 31, make the whole separation plasma bag 2 that separate of plasma that detect that can be accurate in the separation process, improve the separation effect of plasma and red blood cell.

Because the top end of the plasma bag 2 cannot accurately correspond to the horizontal detection probe 31 under the condition of large specification difference, and the height deviation between the two is caused, in order to solve the problem, the absorbance detector 3 is vertically and slidably embedded in the outer side wall of the back plate 12 (specifically, a vertical sliding groove is formed in the outer side wall of the back plate 12, not shown in the figure, and the absorbance detector 3 is embedded in the sliding groove to vertically slide), and preferably, a fastening bolt 7 which is tightly pressed against the outer side wall of the back plate 12 is further arranged at the bottom of the absorbance detector 3. After the absorbance detector 3 and the horizontal detection probe 31 are corresponding to the top end of the plasma bag 2, the absorbance detector 3 is outwards tensioned and tightly attached to the inner wall surface of the vertical chute through the fastening bolt 7, so that the detection position of the horizontal detection probe 31 is limited.

Meanwhile, in order to enable the horizontal detection probe 31 to vertically slide in the back plate 12, a vertical through groove 12a matched with the horizontal detection probe 31 to vertically slide is further formed in the back plate 12.

Specifically, as shown in fig. 3, the sealing structure includes a support 4 disposed on the surface of the base 11, a sealing plate 5 blocking the conduit 21 from penetrating is hinged in the support 4, and a micro motor (not shown in the figure) for driving the sealing plate 5 to rotate is disposed on one side of the support 4. After the information is fed back through the horizontal detection probe 31, the control device drives the micro motor to act and drives the sealing plate 5 to press the conduit 21 on the surface of the support 4, so that the tube body of the conduit 21 is deformed to block the circulation of the conduit, and the risk that red blood cell serous fluid flows into separated blood plasma is avoided. In another preferred embodiment (not shown in the figures), a driving cylinder for driving the driving rod 14 to lift is disposed on the base 11, and is connected to the control device, and the driving cylinder is controlled to achieve automatic pressing of the pressing plate 13, and when the level detection probe 31 detects red blood cell slurry, feedback information is fed back to the control device, and the control device stops the pressing action of the driving cylinder on the pressing plate 13, thereby achieving full-automatic separation operation.

In order to solve the problem, as shown in fig. 1, clamp bodies 6 for suspending the top end of the plasma bag 2 at a fixed height are symmetrically arranged on two sides of the top end of the pressing plate 13, and the clamp bodies are arranged on two sides of the top end of the pressing plate 13. The top end of the plasma bag 2 is clamped to be high through the clamp body 6, the influence of the sliding falling of the plasma bag 2 is avoided, the top end of the plasma bag 2 corresponds to the level of the horizontal detection probe 31 all the time, the influence of the specification of the plasma bag 2 is avoided, and meanwhile, the height of the absorbance detector 3 is reduced.

The principle of the utility model is as follows: place plasma bag 2 between clamp plate 13 and backplate 12 to through the clamp 6 of symmetry with its level fixed high suspension, through the drive actuating lever 14 and continuously extrude plasma bag 2 through clamp plate 13, after level detection probe 31 detected the red blood cell thick liquid, feed back information feedback to controlling means, controlling means drive micro motor action, and drive closing plate 5 compresses tightly pipe 21 on support 4 surface, make pipe 21 body deformation and separation its circulation, and then realize the effective separation operation of plasma and red blood cell thick liquid.

The foregoing shows and describes the general principles, essential features, and advantages of the utility model.
