Wherein, the pipette 4 can be connected with the inlet of imbibition pump, and the imbibition device can be through the pump body fixed mounting of imbibition pump on first moving part 6.
The ultraviolet disinfection device 3 is used for being installed on the second movable member 33, and the ultraviolet disinfection device 3 can be an ultraviolet disinfection lamp or the like.
The turntable 1 is linked with the second movable member 33, and the turntable 1 is used for driving the test tube 2 to rotate to the liquid suction position and driving the second movable member 33 to move, so that the ultraviolet disinfection device 3 on the second movable member 33 is lowered from the first position to the second position, and disinfection treatment is performed on one side of the liquid suction tube 4 from top to bottom. Wherein, when test tube 2 was located the imbibition position, test tube 2 was located pipette 4 under, and pipette 4 can stretch into the interior blood sample that absorbs of test tube 2 when descending.
The driving mechanism is used for driving the first movable piece 6 to rotate when the ultraviolet disinfection device 3 moves to the second position, so that the other side of the pipette 4 faces the ultraviolet disinfection device 3; then the first movable piece 6 is driven to descend, so that the pipette 4 extends into the test tube 2, and the other side of the pipette 4 is sterilized by the ultraviolet sterilizing device 3 from bottom to top.
The operation process of the high-efficiency blood analysis sampling device for medical treatment is as follows: the turntable 1 firstly drives the test tube 2 to rotate to a liquid absorption position right below the liquid absorption tube 4, meanwhile, the turntable 1 also drives the second movable piece 33 to descend, so that the ultraviolet disinfection device 3 on the second movable piece 33 descends from the first position to the second position, and the ultraviolet disinfection device 3 can disinfect one side of the liquid absorption tube 4 from top to bottom in the descending process; then the driving mechanism drives the first movable member 6 to rotate in situ, and the first movable member 6 drives the pipette 4 to rotate 180 degrees, so that the other side of the pipette 4 faces the ultraviolet disinfection device 3; then the driving mechanism continues to drive the first moving part 6, the first moving part 6 drives the pipette 4 to descend, so that the pipette 4 extends into the test tube 2 to suck the blood sample, wherein the other side of the pipette 4 is disinfected by the ultraviolet disinfection device 3 from bottom to top in the descending process.
In the above-mentioned example, both cooperations of second moving part 33 and actuating mechanism can disinfect to one side of pipette 4 earlier, then disinfect to the opposite side of pipette 4 again to can reach and adopt single ultraviolet ray degassing unit 3 can all disinfect the effect to the both sides of pipette 4, and then can prevent that pipette 4 from causing the pollution to blood sample when the imbibition, improve the accuracy that blood sample detected.
In order to realize the function of the aforementioned driving mechanism, the driving mechanism can drive the first movable member 6 to rotate and also drive the first movable member 6 to descend, as shown in fig. 4, the driving mechanism can include a lifting member 24 to drive the first movable member 6 to move through the lifting member 24. When the ultraviolet disinfection device 3 moves to the second position, the lifting piece 24 is used for firstly descending to the first set position so as to drive the first movable piece 6 to rotate; then, the first movable member 6 is lowered to a second set position to drive the first movable member to be lowered together. In order to realize the function of the lifting member 24, as shown in fig. 5, the sampling mechanism further includes a fixing shaft 8, and a limit protrusion 81 is provided on one side of the fixing shaft 8, and the limit protrusion 81 may be integrally formed on the fixing shaft 8. The first movable member 6 is used for being sleeved on the fixed shaft 8. A gap is formed between the first movable piece 6 and the fixed shaft 8, so that the first movable piece 6 can move relative to the fixed shaft 8. Wherein, the first movable element 6 is located on the upper side of the limit bump 81 at the initial position. The limit protrusion 81 is used to abut against the lower side of the first movable member 6 located at the initial position, so as to limit the first movable member 6 above. As shown in fig. 6 to 8, the outer wall of the first movable member 6 is provided with a spiral track, and one side of the first movable member is provided with a first avoiding hole 602 penetrating through both ends. The lifting member 24 is adapted to slidably engage with the rail, so as to drive the first movable member 6 to rotate on the upper side of the limit protrusion 81 through the rail when the first movable member is lowered to the first set position, so that the limit protrusion 81 is opposite to the first avoiding hole 602 on the first movable member 6; then when the first movable piece 6 descends to a second set position, the first movable piece 6 is driven to descend together by pushing the track.
In the above example, the first movable member 6 is located above the limit protrusion 81 in the initial position, and the first movable member 6 can rotate relative to the limit protrusion 81. In order to reduce the frictional resistance when the first movable element 6 rotates relative to the limit protrusion 81, preferably, a first ball may be disposed above the limit protrusion 81 to abut against the lower side of the first movable element 6 located at the initial position through the first ball. The lifting piece 24 is pressed against the side wall of the track in the process of descending to the first position, so that the first moving piece 6 rotates relative to the limiting convex block 81 until the pipette 4 rotates 180 degrees, and at the moment, the limiting convex block 81 is separated from the contact with the first moving piece 6 and is opposite to the first avoiding hole 602 on the first moving piece 6; then, when the lifting member 24 continues to descend, because the first movable member 6 does not have the block of the limiting protrusion 81, the first movable member 6 can descend together under the driving of the lifting member 24, so that the pipette 4 can extend into the test tube 2 to suck the blood sample.
In order to save space, it is preferable that the pipette 4 and the fixed shaft 8 are coaxially provided. As shown in fig. 7 and 8, the first movable member 6 is connected to a fixed seat 11 through a connecting rod 10, one end of the connecting rod 10 is fixedly connected to the first movable member 6, the other end of the connecting rod 10 is fixedly connected to the fixed seat 11, and the number of the connecting rods 10 may be two or more, and the connecting rods are sequentially and uniformly arranged at intervals. The lower end of the fixed shaft 8 is suspended between the first movable member 6 and the fixed base 11. Wherein, the imbibition device is installed on the fixed seat 11 to be connected with the first movable part 6 through the fixed seat 11. In this example, when the first movable part 6 rotates, the pipette 4 is driven to rotate synchronously about its axis.
In order to prevent the first movable member 6 from being separated from the fixed shaft 8 when it descends, it is preferable that, as shown in fig. 7, the lower end of the fixed shaft 8 is provided with a first position-limiting ring 12, and the first position-limiting ring 12 is fastened to the lower end of the fixed shaft 8. The first limit ring 12 is used for abutting against the lower side of the first moving member 6 when the lifting member 24 descends to the second set position, so as to limit the stop of the first moving member 6.
In order to enable the lifting member 24 to drive the first movable member 6 to return to the initial position when rising, preferably, as shown in fig. 7, the sampling mechanism may further include a second limiting ring 9, where the second limiting ring 9 is configured to be sleeved on the fixed shaft 8 and axially and relatively fixed with the fixed shaft 8, for example, the second limiting ring 9 may be clamped on the fixed shaft 8 or integrally formed on the fixed shaft 8. The second limiting ring 9 is located above the limiting protrusion 81, and the second limiting ring 9 is used for abutting against the upper side of the first movable member 6 when the lifting member 24 returns to the first setting position, and making the first movable member 6 rotatable. Specifically, when the lifting member 24 returns to the first setting position, the lifting member 24 drives the first movable member 6 to ascend together, at this time, the upper side of the first movable member 6 abuts against the second limit ring 9, and the two are rotationally matched in the circumferential direction, and when the lifting member 24 continues to ascend, the lifting member 24 drives the first movable member 6 to rotate back to the initial position through the rail.
