Description

Pasteur pipet rack

Technical Field

The utility model relates to a test-tube rack technical field, especially a pasteur pipette rack.

Background

Pasteur pipettes are used in many aspects of assisted reproductive technology, including egg picking, in vitro fertilization, intracytoplasmic sperm injection, cultured oil microdroplets, embryo transfer, etc., and as more and more patients choose to pick up eggs and transfer embryos, the daily amount of pasteur pipettes required becomes greater.

According to the relevant regulations of the assisted reproduction technology state, every patient needs to use a brand-new pasteur pipette to perform work such as embryo transfer and freezing. Meanwhile, the large diameter of the pasteur tube mouth can not be directly used for freezing early embryos and embryo transfer work, so a large amount of work is needed for the needle pulling work of the pasteur tube every day, and the pasteur tube is mainly drawn into thin tubes with different diameters according to different purposes by depending on personal experience. The Pasteur pipettes with original calibers are needed when eggs are picked up, the Pasteur pipettes with calibers slightly larger than the diameter of oocytes are needed to be drawn for embryo transfer, the Pasteur pipettes with the calibers consistent with the diameter of the blastocyst need to be drawn when the blastocyst is frozen, so that the Pasteur pipettes with different calibers need to be drawn according to actual use conditions, the drawing of the Pasteur pipettes mainly depends on personal experience, and each batch of qualified Pasteur pipettes can be obtained only by consuming a large amount of manpower and material resources. At present, the drawn pasteur pipette is placed on the table top of the operation box, the table top slightly shakes or accidentally touches the pasteur pipette, needle breakage of the pasteur pipette is easily caused, a waste needle is caused, and the pasteur pipette cannot be used any more, and the existing test tube rack is not suitable for placing the pasteur pipette.

SUMMERY OF THE UTILITY MODEL

Aiming at the problems, the Pasteur pipette rack is provided, and the problem that the existing test tube rack is not suitable for placing a Pasteur pipette is solved.

In order to achieve the above purpose, the utility model adopts the technical proposal that: the utility model provides a pasteur pipette rack, includes the support body, be equipped with a plurality of test tube hole and a plurality of lantern ring on the support body, test tube hole and lantern ring one-to-one, the lantern ring includes big ring and ringlet, the ringlet is fixed in the lower extreme of big ring, the external diameter of big ring is greater than the diameter in test tube hole, the ringlet cover is located in the test tube hole.

Further, a rubber layer is fixedly arranged on the outer wall of the small ring. The rubber layer possesses elasticity, can be better with test tube hole cooperation for the lantern ring is firm.

Further, the rubber layer is in interference fit with the test tube hole. Interference fit can make the lantern ring can firmly be in the test tube hole, avoids becoming flexible between lantern ring and the test tube hole.

Further, the center lines of the large ring and the small ring are coincident.

Further, the outer wall of macrocycle is equipped with scale ring and pointer, scale ring rotates the cover to be located outside the macrocycle, be equipped with the scale on the scale ring, the pointer is located the downside of scale ring, the pointer with the axis of macrocycle is parallel, the lower extreme fixedly connected with lug of pointer, the lug is fixed in the outer wall of macrocycle, the upper end subsides of pointer are located the surface of scale ring. Through rotatory scale ring for corresponding scale turns to pointer department, marks the bore of placing the pasteur straw here, is convenient for visualize, takes wrong pasteur straw when avoiding using.

Further, the scale ring is made of hard plastics, and the thickness of the scale ring is 2 mm.

Furthermore, a limiting bolt is arranged on the scale ring, the limiting bolt penetrates through the scale ring and abuts against the outer wall of the large ring, and the limiting bolt is in threaded connection with the scale ring. When the scale is selected to the required rotary scale ring, the limiting bolt is unscrewed firstly, then the scale ring is rotated, the required scale is rotated to the pointer, the limiting bolt is screwed up at last, the scale ring is fixed, and the scale ring is prevented from rotating due to the fact that the frame body shakes and the like.

Due to the adoption of the technical scheme, the beneficial effects of the utility model are that:

1. the pasteur pipette rack comprises a rack body and a lantern ring, the pasteur pipette can be placed by sleeving the lantern ring into the test tube hole of the rack body, so that the rack body can directly adopt the existing test tube rack without changing the test tube rack, only the lantern ring needs to be manufactured, the modification is small, and the cost is low; when not needed for placing pasteur pipettes, the collar can be removed and the rack used for placing test tubes. The fine needle of pasteur straw passes the ringlet and enters into in the test tube hole, and is great with the distance of test tube pore wall, and when pasteur straw rack rocked, the fine needle of pasteur straw can not touch the test tube pore wall, so the utility model discloses a pasteur straw rack can reduce the fine needle fracture of pasteur straw.

2. The utility model discloses an outer wall of macrocycle is equipped with scale ring sum pointer, puts into the pasteur straw after, rotates the scale ring, marks the bore of pasteur straw, avoids medical staff to take wrong pasteur straw when using.
