The clocking information can be obtained ovarian follicle liquid pipe number, volume, operating time, and show on the display 24.In puncturing operation knot
Shu Shi, laboratory technician can effectively read the parameters such as ovarian follicle liquid pipe number, volume, operating time, avoid in surgical procedure and hold on one side
Liquor folliculi is recorded on one side and the confusion and cross contamination risk that generate, and can perform the operation to the entire oocyte pickup of clinician
Process carries out more accurate quality control.
Specifically, the counts that central processing unit finally obtains are ovarian follicle liquid pipe number；It is converted by quality volume public
Formula: volume=(gross mass-test tube quality) * liquor folliculi density * 100% can be obtained the volume of each pipe liquor folliculi；Central processing
The timing duration that device finally obtains is operating time.
The use step of the utility model are as follows:
1, mechanical arm is located at initial position, i.e. mechanical arm is stretched out from principal arm 2 towards transmitting window, extension arm 3, and mechanical
Arm passes through pass-through box and enters operating room, as shown in Figure 3；
Ova harvest starts, and starts central processing unit, and press the start button 22 of timer 21, timer starts timing；
2, clinician's Transvaginal Ultrasound Conducted Puncture obtains liquor folliculi, and the test tube containing liquor folliculi is inserted into machinery
In the cuvette groove 4 on arm top, weight induction sensor 5 sends weight information to central processing unit, and central processing unit is according to reception
To weight information judge to be put into the test tube equipped with liquor folliculi in cuvette groove 4；
Central processing unit rotates counterclockwise instruction, the second driving motor letter to the second driving motor signal receiver 14
Number receiver 14 drives the rotation of the second motor 8, and adjutage 3 carries out the movement of " contracting ", at this time liquor folliculi to 2 contract of principal arm
Just it is brought back in Embryo Culture room by mechanical arm from operating room, as shown in Figure 4；
3, after the movement that adjutage 3 completes " contracting ", central processing unit transmission rotates counterclockwise instruction and believes to the first operation
Number receiver 13, then first motor 7 drives central rotary shaft 1 to be rotated in the counterclockwise direction, and mechanical arm carries out moving for " turning "
Make, as shown in Figure 5；
The pillar 25 that mechanical arm turns to gag lever post 10 moves along limiting slot 28 and touches the touching of 26 front end of limit plate
Inductor 27 is counted, mechanical arm stops rotating and towards ultra-clean work station direction at this time, as shown in Figure 6；And at the same time, touching
Sensor for countering 27 counts once, and count information is conveyed to central processing unit；
4, after the completion of the movement of " turning ", central processor rotates clockwise finger to the transmission of the second run signal receiver 14
It enables, the second run signal receiver 14 drives the second motor 8 to rotate clockwise with moving gear 15, and the second motor 8 pushes rack gear 16
Adjutage 3 is stretched out forward, mechanical arm carries out the movement of " stretching ", thus before the test tube equipped with liquor folliculi is delivered to ultra-clean work station
Embryo experiments teacher in face of, as shown in Figure 7；
5, embryo experiments teacher removes the test tube containing liquor folliculi from cuvette groove 4, and weight induction sensor 5 will weigh in real time
Information conveyance is measured to central processing unit；Central processing unit judges that test tube is removed from cuvette groove 4, and successively to the second run signal
The transmission of receiver 14 rotates counterclockwise instruction, rotates clockwise instruction to the transmission of the first run signal receiver 13, transports to second
Row signal receiver 14 transmission rotate clockwise instruction, thus make mechanical arm completion " contracting "-" turning "-" stretching " movement and again
Empty cuvette groove 4 is passed through pass-through box to protrude into operating room, mechanical arm is in initial position, to prepare liquor folliculi biography next time
It passs；
6, after last pipe liquor folliculi is completed to transmit, embryo experiments teacher presses the end key 23 on timer, timing knot
Beam；Timer triggers the data processing that central processing unit carries out clocking information, weight information and count information, and central processing unit obtains
The parameters such as the ovarian follicle liquid pipe number of entire ova harvest acquisition, the volume of each pipe liquor folliculi and used time for entirely performing the operation and pass through
Display screen 24 is shown, for lab assistant registration record and completes the quality control performed the operation to this oocyte pickup of clinician
System.
The utility model entirely to perform the operation only need 2 medical workers (clinician of 1 puncture ovarian follicle and 1 it is aobvious
Under micro mirror ovum pick up embryo experiments teacher), effectively it is labor-saving and meanwhile also avoid in the transmittance process of midway because liquid shake
Out personnel are caused with the risk of infection, and entire transmittance process carries out in constant temperature cuvette groove, compared to the biography that hand passs hand
Mode is passed, it is more preferable to the heat insulation effect of egg mother cell；Lab assistant can intuitively be read after operation by display screen
The information such as the volume of an ovarian follicle liquid pipe number, each pipe liquor folliculi that rounding ova harvest acquires and the used time entirely performed the operation, then into
The typing of row information works, and avoids the confusion and intersection for being recorded and being generated while holding liquor folliculi in surgical procedure
Pollution risk, and more accurate quality control can be carried out to the entire oocyte pickup surgical procedure of clinician.
To sum up, the utility model has structure simple, flexible and efficient, avoids infection while having good heat preservation effect, energy
Quality Control, labor-saving advantage can be facilitated again by alleviating medical worker's working strength.
Content described in this specification embodiment is only an enumeration of the implementation forms of the utility model concept, this is practical new
The protection scope of type should not be construed as being limited to the specific forms stated in the embodiments, and the protection scope of the utility model is also wrapped
Include those skilled in the art according to the utility model design it is conceivable that equivalent technologies mean.
