Description

Technical Field

[0001] The utility model relates to the technical field of biological scientific research, in particular to a serum purification device. Background Technique

[0002] Bovine serum is the natural culture medium with the largest consumption in cell culture. It contains rich nutritional components essential for cell growth, can provide hormones for maintaining exponential cell growth, nutrients that are absent or in small amounts in the basal medium, and mainly low-molecular-weight nutrients. It is commonly used for in vitro culture of animal cells and has extremely important functions.

[0003] At present, for the existing bovine serum purification device, a Chinese patent with the publication number CN211141933U discloses a bovine serum purification device, including a base. A rotation driving mechanism is provided at the bottom end of the base, and a rotating cylinder is rotatably connected to the center of the top end of the base. A fixed sleeve is sleeved and rotatably connected to the middle part outside the rotating cylinder. A fixed support is fixedly connected between the bottom end of the fixed sleeve and the base. A fixed rod is fixedly connected to the top end of the fixed sleeve, and a top seat is fixedly connected to the top end of the fixed rod. The rotating cylinder is coaxially rotatably connected to a fixed pipe, and a suction mechanism is provided on the fixed pipe. A delivery pump is fixedly connected to the top end of the top seat, and an external delivery pipe is fixedly connected between the input end of the delivery pump and the fixed pipe. The suction mechanism includes an internal absorption pipe arranged in the fixed pipe. This utility model can centrifuge bovine blood through the rotation driving mechanism and rotation to obtain the upper-layer bovine serum, and then suck it according to the layer with high serum purity through the suction mechanism, so that the prepared serum has high purity.

[0004] However, in actual use of this existing technology, during the process of sucking by extending into the high-purity serum layer, impurities in the lower layer may still be sucked up. Therefore, the high purity of the serum cannot be guaranteed, and the use effect still needs to be further optimized.

[0005] Therefore, this application provides a serum purification device to solve the above technical problems. Summary of the Utility Model

[0006] The technical problem to be solved by the utility model is to provide a serum purification device to solve the problem that the existing serum purification device is likely to suck out impurities in the lower layer and cannot guarantee the purity of the serum.

[0007] To solve the above technical problems, the utility model provides the following technical solutions:

[0008] A serum purification device, including a base, a rotatable turntable is rotatably installed in the middle of the upper end surface of the base, a rotating cylinder is fixed on the turntable, and a fixed frame is fixed at one end of the base. The top of the fixed frame extends directly above the rotating cylinder and is threadedly inserted with a vertical screw rod. The lower end of the screw rod is rotatably installed with a suction cylinder for extending into the rotating cylinder. One side of the top of the suction cylinder is connected with a suction pipe. The bottom of the suction cylinder is rotatably installed with an installation ring adapted to the inner diameter of the rotating cylinder. A ceramic composite membrane is laid in the installation ring. A suction hole is opened on one side of the bottom of the suction cylinder, and the suction hole is located above the installation ring.

[0009] Optionally, a screw hole for the vertical penetration of the screw rod is opened at the top of the fixed frame. The top end of the screw rod is located above the fixed frame and is fixed with a screwing cap.

[0010] Optionally, a vertical limit sliding groove is opened at the outer edge of the installation ring, and a vertical limit rib is constructed on the inner wall of the rotating cylinder. The limit rib is in vertical sliding fit with the limit sliding groove.

[0011] Optionally, a discharge pipe is installed at the bottom of the rotating cylinder. A valve is installed on the discharge pipe, and a liquid level window is arranged on the side of the rotating cylinder.

[0012] Optionally, a limit ring is fixed in the middle of the lower end surface of the turntable, and a plurality of balls are fitted and installed on the lower end surface of the limit ring.

[0013] Optionally, a motor is fitted in the middle of the lower end surface of the turntable. The motor is fixed in the base, and the motor shaft is fixed at the center point of the lower end surface of the turntable.

[0014] Optionally, the suction pipe is connected with a delivery pump, and the delivery pump is installed on the side of the fixed frame.

[0015] Compared with the prior art, the present utility model has at least the following beneficial effects:

[0016] In the above solution, thanks to the cooperation of the suction cylinder, the installation ring and the ceramic composite membrane, when the lower end of the suction cylinder is extended to the position of the high-purity serum layer in the rotating cylinder, the ceramic composite membrane laid in the installation ring can be used to separate from the impurities in the lower layer, so that when the suction hole at the bottom of the suction cylinder sucks the high-purity serum, impurities can be effectively avoided from mixing in, thus ensuring the serum purity and having a good use effect.

[0017] At the same time, thanks to the setting of the limit ring and the balls on the lower end surface of the turntable, the friction can be reduced by using the balls, so that when the motor drives the turntable to drive the rotating cylinder to perform a rotating centrifugation operation, it is smoother and conducive to ensuring the centrifugation effect.

[0018] In summary, the present device can separate the lower layer of blood when aspirating the upper layer of serum to avoid the mixing of impurities, thereby effectively ensuring the purity of the serum. Moreover, through the structural arrangement for reducing friction, the centrifugation effect of the blood can be further improved, and the overall use effect is good.

[0032] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a serum purification device, including a base 1, a rotatable rotating disk 2 is rotatably installed in the middle of the upper end surface of the base 1, a rotating drum 3 is fixed on the rotating disk 2, and a fixing frame 4 is fixed at one end of the base 1, the top of the fixing frame 4 extends to the top of the rotating drum 3, and a vertical screw 5 is threadedly inserted, and a screw hole for the screw 5 to vertically pass through is opened at the top of the fixing frame 4, the top of the screw 5 is located above the fixing frame 4, and a screw cap is fixed, so that the rotatable screw 5 can be vertically lifted and lowered directly above the rotating drum 3.

[0033] The lower end of the screw 5 is rotatably installed with a suction cylinder 6 for extending into the rotating cylinder 3. A suction tube 7 is connected to one side of the top of the suction cylinder 6. The suction tube 7 is connected to the interior of the suction cylinder 6, and the suction tube 7 is connected to a delivery pump 701. The delivery pump 701 is installed on the side of the fixed frame 4. The delivery pump 701 and the suction tube 7 can cooperate with the suction cylinder 6 to suck serum.

[0034] At the same time, a mounting ring 8 adapted to the inner diameter of the rotating drum 3 is rotatably mounted at the bottom of the suction cylinder 6, a ceramic composite membrane 9 is laid inside the mounting ring 8, and a suction hole 601 is opened on one side of the bottom of the suction cylinder 6, and the suction hole 601 is located above the mounting ring 8. Therefore, the suction cylinder 6 can drive the mounting ring 8 to extend into the rotating drum 3, so as to facilitate the ceramic composite membrane 9 to separate impurities in the lower layer of blood to prevent impurities from mixing into the upper layer of serum.

[0035] In specific implementation, Figure 3 As shown, a vertical limiting groove 801 is provided on the outer edge of the mounting ring 8, and a vertical limiting ridge 303 is constructed on the inner wall of the rotating drum 3. The limiting ridge 303 vertically slides with the limiting groove 801, so that the mounting ring 8 can be stably lifted and lowered vertically in the rotating drum 3.

[0036] like Figure 1 and Figure 4 As shown, a limiting ring 201 is fixed in the middle of the lower end surface of the rotating disk 2, and a plurality of balls 202 are embedded and installed on the lower end surface of the limiting ring 201, and a motor 203 is matched in the middle of the lower end surface of the rotating disk 2, and the motor 203 is fixed in the base 1, and the shaft of the motor 203 is fixed at the center point of the lower end surface of the rotating disk 2. Therefore, the rotating disk 2 and the drum 3 can be driven to rotate by the motor 203 to perform blood centrifugation, and the setting of the balls 202 can reduce friction and effectively maintain the smoothness of centrifugal rotation, and the use effect is good.

[0037] In addition, in this embodiment, a discharge pipe 301 is installed at the bottom of the rotating drum 3 , a valve is installed on the discharge pipe 301 , and a liquid level window 302 is provided on the side of the rotating drum 3 .

[0038] The working principle provided by the present utility model for this serum purification device is as follows. When in use, blood can be placed in the rotating drum 3. By starting the motor 203, the rotating disk 2 is controlled to drive the rotating drum 3 to rotate, thereby centrifuging the blood. After the centrifugation process, the screw 5 can be rotated to drive the suction cylinder 6 to descend and extend to the position of the high-purity serum layer in the rotating drum 3. The ceramic composite membrane 9 laid in the mounting ring 8 is used to separate the impurities in the lower layer, so that when the suction holes 601 at the bottom of the suction cylinder 6 suck the high-purity serum, impurities can be effectively prevented from mixing in, thus ensuring the purity of the serum and having a good use effect.

[0039] In summary, this device can separate the lower layer of blood when sucking the upper-layer serum to avoid the mixing of impurities, thereby effectively ensuring the purity of the serum. Moreover, through the structural setting for reducing friction, the blood centrifugation effect can be further improved, and the overall use effect is good.
