Abstract

The utility model discloses an EP pipe frame convenient for embryo biopsy operation, which comprises an EP pipe frame body provided with a plurality of EP pipe placing holes, wherein the edge of the EP pipe frame body is provided with at least one arc-shaped notch matched with the outer edge of a culture dish, and the EP pipe placing holes are arranged in a manner of inclining to the horizontal plane. The utility model has the technical effects that the EP tube arranged on the device is inclined, so that an experimenter can directly hold the glass needle with one hand to smoothly transfer the embryonic cell sample into the biopsy liquid of the EP tube without taking down the EP tube to incline, thereby saving time and labor and improving efficiency. The EP pipe support is made of transparent materials, is convenient for direct observation, is matched with the edge of the culture dish, shortens the moving range of the embryo biopsy product, is simple and stable in operation process, and is not easy to cause the loss of the embryo cell sample.

Description

Make things convenient for EP pipe support of embryo biopsy operation

Technical Field

The utility model relates to the technical field of medical detection equipment, in particular to an EP pipe frame convenient for embryo biopsy operation.

Background

Pre-embryo implantation genetic testing (PGT) includes pre-embryo implantation genetic diagnosis (PGD) and pre-embryo implantation genetic screening (PGS). PGT carries out detection of pathogenic gene mutation or screening of chromosome abnormality on embryo cells cultured in vitro in the assisted reproductive cycle, so as to select high-quality embryos to be implanted into a mother for conception, and further improve the conception rate of the mother and the quality of a newborn. The application value of PGT in the auxiliary reproduction of China is higher and higher. PGT consists of four steps of embryo biopsy, whole genome amplification, pathogenic variation detection and detection result identification, wherein the embryo biopsy is the initial step of PGT, and the transfer of embryo biopsy products is the main difficulty. The key problem to be solved by PGT is how to transfer the embryo into the biopsy fluid of EP tube without error.

The current EP tube holder and culture dish for embryo biopsy are far apart and the EP tube is placed vertically on the EP tube holder. The EP tube is usually taken down and inclined by an operator with one hand, the embryo is sent into the EP tube by holding the glass needle with the other hand, the operation is complicated, and the embryo loss is easily caused by misoperation.

Disclosure of Invention

In order to overcome the technical problem that the operation is complex and the embryo is easily lost due to the structure of the existing EP pipe frame, the utility model provides the EP pipe frame which is convenient for the embryo biopsy operation.

In order to achieve the technical purpose, the technical scheme of the utility model is that,

the utility model provides a make things convenient for EP pipe support of embryo biopsy operation, places the EP pipe support body 1 in hole including being equipped with a plurality of EP pipes, the edge of EP pipe support body on be equipped with at least one and culture dish outer edge assorted arc breach 2.

According to the EP pipe frame convenient for embryo biopsy operation, the arc edge length of the arc-shaped notch 2 is not less than one fourth of the perimeter of the culture dish.

According to the EP pipe frame convenient for embryo biopsy operation, the friction strip 4 used for increasing the friction force between the arc-shaped notch 2 and a culture dish is arranged on the arc-shaped notch.

According to the EP pipe frame convenient for embryo biopsy operation, the EP pipe placing hole 3 is arranged obliquely to the horizontal plane.

According to the EP pipe frame convenient for embryo biopsy operation, the angle between the EP pipe placing hole 3 and the horizontal plane is 30-60 degrees.

Make things convenient for EP pipe support of embryo biopsy operation, the hole body of hole 3 is placed to each EP pipe, equally divide respectively towards the nearest arc breach 2 setting of distance.

The utility model has the technical effects that the EP tube arranged on the device is inclined, so that an experimenter can directly hold the glass needle with one hand to smoothly transfer the embryonic cell sample into the biopsy liquid of the EP tube without taking down the EP tube to incline, thereby saving time and labor and improving efficiency. The EP pipe support is made of transparent materials, is convenient for direct observation, is matched with the edge of the culture dish, shortens the moving range of the embryo biopsy product, is simple and stable in operation process, and is not easy to cause the loss of the embryo cell sample.

FIG. 3 is a schematic view of the curved notch rubbing strip of the present embodiment;

wherein 1 is EP pipe support body, 2 is the arc breach, and 3 are EP pipe and place the hole, and 4 are the friction strip, 5

Is an EP tube.

Detailed Description

The following examples are intended to further illustrate the utility model and are not to be construed as limiting the utility model.

Referring to fig. 1, an arc-shaped notch 2 is provided on the edge of the EP pipe rack body 1 provided in this embodiment, and the arc-shaped notch 2 matches with the outer edge of the culture dish. This embodiment is through setting up this arc breach 2 on one of them corner of EP pipe support body 1, and the culture dish card is gone into in this arc breach 2, both can shorten and place the distance of hole 3 with the EP pipe, can guarantee again that the culture dish can not slide when the operation to effectively improve operating efficiency.

And according to specific needs, the number of the arc-shaped notches 2 can be also provided in plurality. For example, if the EP pipe rack is provided with dozens or tens of EP pipe placement holes 3, only one arc-shaped notch 2 may not be enough, in which case more than two arc-shaped notches 2 may be provided as needed, and the two arc-shaped notches 2 may be provided on opposite sides of the EP pipe rack. The arc-shaped notch can also be arranged at the corner or the edge of the EP pipe frame according to the requirement.

In order to better stabilize the culture dish on the arc-shaped notch 2, the arc edge length of the arc-shaped notch 2 is one fourth of the perimeter of the culture dish in the embodiment. Likewise, the length of the arc edge can be set according to specific situations in specific use, such as setting the length of the arc edge to be one third or one half of the culture dish.

Referring to fig. 3, in order to prevent the culture dish from being displaced during the operation, a friction strip 4 is fixed on the arc-shaped notch 2 to increase the friction force between the culture dish and the friction strip, so as to prevent the culture dish from rotating or moving. The friction strip can be made of common materials with large friction force, such as rubber strips, silica gel strips, cloth strips and the like.

Referring to fig. 2, the EP tube placing hole 3 of the present embodiment is disposed obliquely to the horizontal plane, wherein the present embodiment adopts a manner of forming an angle of 45 ° with the horizontal plane. In practical situations, the angle can be adjusted according to the operation requirement, such as inclination of 30 degrees or 60 degrees.

And in order to further facilitate the operation, this embodiment also provides the embodiment that the body of each EP pipe placing hole 3 is set towards the arc notch 2 closest to each other. Thus, after the EP tube 5 is put in, the opening of the EP tube 5 faces the culture dish in the arc-shaped notch 2, thereby facilitating the operation.
