Description

Technical Field

[0001] The present invention belongs to the technical field of serum floating clot removal, and specifically relates to a device for electrostatic removal of serum clots. Background Art

[0002] Blood centrifugation is a way of specimen pretreatment in the clinical laboratory. The separated serum or plasma is used for detection and analysis in aspects such as biochemistry, immunology, and coagulation. In the centrifuged serum, due to reasons of the specimen itself (differences in coagulation factors and fibrinogen for each person) or the blood collection tube (there is a ring of blood adsorption at the tube cap of the blood collection tube), some fibrin clots and fibrin filaments will float in the serum. After entering the detection system, it will cause the sampling needle to be blocked or adhered and carried by the sampling needle, directly affecting the sampling volume, and further leading to inaccurate detection results.

[0003] Currently, this step is mainly carried out by laboratory workers who discover and manually pick or suck away the clots and filaments. This process is easily overlooked by inexperienced staff, and samples with clots and fibrin filaments are sent into the detection instrument. Moreover, during the operation of manually picking or sucking away the clots and filaments, the possibility of sample spillage and liquid splashing is increased. And in the case of future fully automated instrument detection without the supervision and handling of staff, this factor greatly affects the accuracy of the detection results.

[0038] As Figure 1-9 shown, a serum clot electrostatic removal device includes a base 4, a moving arm 3, a motorized module 2 and an adsorption module 1. A needle washing groove 42 is provided at the top of the base 4; one end of the moving arm 3 is inserted into the interior of the base 4, and the other end extends in the vertical direction; a control shaft is provided inside the moving arm 3; a driving motor 36 is provided inside the base 4; the driving motor 36 drives the control shaft to rotate; the motorized module 2 is located at one end of the moving arm 3 away from the base 4; the motorized module 2 includes a housing, a transmission assembly 24 and a charge assembly 26; the housing is fixedly connected to one end of the moving arm 3 away from the support column 33; one end of the control shaft away from the driving motor 36 is inserted into the interior of the housing and then connected to the transmission assembly 24; one end of the adsorption module 1 is inserted into the interior of the housing; the charge assembly 26 includes a positive charge port 262, a negative charge port 263 and a conductive member 264; the conductive member 264 is fixedly connected to the adsorption module 1; the control shaft drives the adsorption module 1 to rotate through the transmission assembly 24, so that the conductive member 264 can selectively contact the positive charge port 262 or the negative charge port 263, so that the adsorption module 1 is positively charged or negatively charged.

[0040] It can have a net negative charge based on fibrin. When the adsorption module 1 is inserted into the interior of the test tube 7, the driving motor 36 drives the adsorption module 1 to rotate through the control shaft and the transmission assembly 24, so that the conductive member 264 contacts the positive charge port 262. At this time, the adsorption module 1 is positively charged. Applying the principle of opposite-sex attraction, the fibrin clots and fibrin filaments in the serum can be effectively adsorbed. When the adsorption module 1 enters the needle washing groove 42, the driving motor 36 drives the adsorption module 1 to rotate through the control shaft and the transmission assembly 24, so that the conductive member 264 contacts the negative charge port 263, making the adsorption module 1 negatively charged. Applying the principle of same-sex repulsion, the fibrin clots and fibrin filaments attached to the adsorption module 1 fall into the interior of the needle washing groove 42.

[0042] As Figure 4 shown, the limit bracket 5 includes a fixed groove 51, a sliding groove 52 and a driver; the fixed groove 51 is fixedly connected to the side wall of the base 4; the driver is located inside the base 4; the sliding groove 52 is located on the side wall of the base 4, and one end of the driver extends out of the base 4 and is fixedly connected to the sliding groove 52.

[0043] During use, the test tube rack 6 is installed on the fixed groove 51 and the sliding groove 52. After the adsorption module 1 completes the adsorption of the blood inside a test tube 7, the driver drives the sliding groove 52 to drive the test tube rack 6 to move towards the direction of the fixed groove 51. So as to facilitate the adsorption module 1 to insert into the inside of the next test tube 7.

One end of the slider 53 extends out of the base 4 through the sliding groove and is fixedly connected to the sliding groove 52. The adjustment motor 56 drives the transmission roller 54 to rotate, which drives the slider 53 to move along the sliding groove, thereby driving the sliding groove 52 to move, so as to push the test tube rack 6 to move.

[0045] Preferably, a control wheel 541 is provided on the transmission roller 54; an adjustment wheel 55 is provided on the adjustment motor 56; the adjustment wheel 55 is engaged with the control wheel 541.

[0049] Specifically, both ends of the first connecting member 321, the end of the second connecting member 252 away from the housing, and the end of the third connecting member away from the base 4 are frosted surfaces. When the telescopic motor 37 drives the lifting column 31 to rise, the first connecting member 321 contacts the third connecting member, and the two frosted surfaces contact each other. There is a relatively high friction force between the first connecting member 321 and the third connecting member, enabling the third connecting member to rotate following the first connecting member 321. When the telescopic motor 37 drives the lifting column 31 to descend, the first connecting member 321 contacts the second connecting member 252, and the two frosted surfaces contact each other. There is a relatively high friction force between the first connecting member 321 and the second connecting member 252, enabling the second connecting member 252 to rotate following the first connecting member 321.

The first connecting member 321 is connected to the third connecting member, causing the transmission shaft 32 to drive the lifting column 31 to rotate, so as to drive the motorized module 2 to rotate, enabling the adsorption module 1 to be aligned with the needle washing groove 42 or the test tube 7. When the telescopic motor 37 drives the lifting column 31 to descend, the adsorption module 1 is inserted into the test tube 7 or the needle washing groove 42.

When the adsorption module 1 carries positive electricity, it adsorbs the fibrin clots and fibrin filaments in the serum on the surface of the adsorption module 1. When the adsorption module 1 carries negative electricity, the fibrin clots and fibrin filaments adsorbed on the surface of the adsorption module 1 will fall into the needle washing groove 42.

The purpose of the insulating layer 12 is to prevent dust in the air from being adsorbed on the adsorption module 1 under the action of electric charges, thereby causing serum contamination. At the same time, it can also prevent the electric charges on the adsorption needles 11 from neutralizing the electric charges on the fibrin clots and fibrin filaments being aspirated.

[0075] The working principle of this embodiment:

[0076] The driver drives the sliding groove 52 to drive the test tube rack 6 to move towards the fixed groove 51, so that the test tube 7 is aligned with the adsorption module 1. The telescopic motor 37 drives the lifting column 31 to descend, so that the adsorption module 1 is inserted into the test tube 7. At this time, the first connecting member 321 contacts the second connecting member 252. The driving motor 36 drives the adsorption module 1 to rotate through the control shaft and the transmission assembly 24, so that the conductive member 264 contacts the positive charge port 262. At this time, the adsorption module 1 is positively charged. Applying the principle of opposite charges attracting, the fibrin clots and fibrin filaments in the serum can be effectively adsorbed. Then the telescopic motor 37 drives the lifting column 31 to rise, so that the adsorption module 1 is separated from the test tube 7. At this time, the first connecting member 321 contacts the third connecting member. The driving motor 36 drives the mobile module 2 to rotate through the transmission shaft 32 and the lifting column 31, driving the adsorption module 1 to gradually align with the needle washing groove 42. The telescopic motor 37 drives the lifting column 31 to descend, so that the adsorption module 1 is inserted into the needle washing groove 42. The first connecting member 321 is connected to the second connecting member 252, so that the transmission shaft 32 drives the output device 25 to rotate. The output device 25 drives the adsorption module 1 to rotate, so that the conductive member 264 can selectively contact the negative charge port 263. At this time, the adsorption module 1 is negatively charged. Applying the principle of like charges repelling, the fibrin clots and fibrin filaments adsorbed on the surface of the adsorption module 1 will fall into the needle washing groove 42.

[0077] Subsequently, the telescopic motor 37 drives the lifting column 31 to rise, causing the adsorption module 1 to disengage from the needle washing groove 42. At this time, the first connecting member 321 contacts the third connecting member, and the driving motor 36 drives the motorized module 2 to rotate through the transmission shaft 32 and the lifting column 31, driving the adsorption module 1 to reach above the needle parking groove 43 for drying the adsorption module 1. After the adsorption module 1 is dried, the driving motor 36 drives the motorized module 2 to rotate, and at the same time, the driver drives the sliding groove 52 to drive the test tube rack 6 to move towards the fixed groove 51, aligning the test tube 7 with the adsorption module 1 to remove the fibrin clot and fibrin filaments in the next test tube 7.
