These and other characteristics of the invention will become apparent from the following description of a preferred form, given as a non-limiting example, with reference to the accompanying drawings.

It is also understood that, although the present invention has been described with reference to some specific examples, a person of skill in the art shall certainly be able to achieve many other equivalent forms of the invention, having the characteristics as set forth in the claims and hence all coming within the field of protection defined thereby.

The above and other aspects, features and advantages of the present disclosure will become more apparent in view of the following detailed description when taken in conjunction with the accompanying drawings.

Specific embodiments of the present disclosure are described hereinafter with reference to the accompanying drawings; however, it is to be understood that the disclosed embodiments are merely examples of the disclosure that may be embodied in various forms. Well-known and/or repeated functions and structures have not been described in detail so as not to obscure the present disclosure with unnecessary or unnecessary detail. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present disclosure in virtually any appropriately detailed structure.

The specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," which may each refer to one or more of the same or different embodiments in accordance with the disclosure.

The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1 and 2, the present invention provides a culture assembly for culturing a sample 6, the culture assembly comprising:

a culture plate 1 having a plurality of culture units 3 for accommodating samples 6 to be cultured; and

and an auxiliary support 2 disposed on the culture plate 1, wherein the auxiliary support 2 has a plurality of position-limiting units 4 for extending into the culture unit 3 and cooperating with the culture unit 3 to limit the sample 6 at a predetermined position of the culture unit 3.

The embodiment of the utility model provides a beneficial effect who possesses includes simple structure, easily preparation, can effectively spacing sample 6 in the position department of predetermineeing of cultivateing unit 3 moreover, the high flux of being convenient for detects. Especially when sample 6 is biological sample 6, and need carry out the electrophysiological activity to this biological sample 6 and detect, fix spacing biological sample 6 through the culture assembly in this application embodiment, can carry out effective restriction to the position of biological sample 6, guarantee going on smoothly of electrophysiological activity detection to and the rate of accuracy of detection data.

Specifically, as shown in the figure, the culture unit 3 in the present embodiment is integrally formed with the culture plate 1, but may be provided independently. In operation, each culture unit 3 may be formed by extending a portion of the plate 1 vertically outward. Wherein, cultivate unit 3 and be the column, the shape differs, and cultivate unit 3 in this embodiment is cylindricly to have the open holding chamber of one end, cultivate unit 3 and be uncovered towards the one end of cultivateing board 1 promptly, sample 6 is located this holding chamber.

Further, the auxiliary stand 2 in the present embodiment includes a base plate 5, and the position limiting unit 4 is integrally formed with the base plate 5, but may be separately provided. In operation, a part of the substrate 5 may be extended vertically towards the direction of the culture plate 1 to form the limiting unit 4, and in this embodiment, the fixing limiting unit 4 is a hollow cylinder, specifically, a cylinder, or a cylinder with other shapes. In addition, preferably, the limiting units 4 of the auxiliary stent 2 in this embodiment are all made of an ultralow adsorption hydrophobic material, so as to prevent the biological sample 6 from adhering to the limiting units 4.

In practice, for example, a plurality of position-limiting units 4 on the auxiliary support 2 may be arranged in a matrix type, such as 6x8,8x12, and the number of the culture units 3 and the position-limiting units 4 may be the same and one-to-one, or may be different, such as smaller than the number of the culture units 3, and a plurality of auxiliary supports 2 may be arranged on one culture plate 1. Further, for example, when culturing the biological sample 6, the auxiliary support 2 is firstly stacked on the culture plate 1, so that the position-corresponding limiting unit 4 correspondingly extends into the culture unit 3, and thus the limiting unit 4 and the corresponding culture unit 3 cooperate to form a limiting chamber for accommodating and limiting the biological sample 6, and the preset position is located in the limiting chamber, and the preset position is not unique, such as the center of the limiting chamber. After the limiting unit 4 extends into the culture unit 3, a gap is required between the bottom of the limiting unit 4 and the culture unit 3, and the gap is preferably 100-200 micrometers, that is, the limiting unit 4 is suspended in the culture unit 3. The gap is arranged so that when the culture assembly in this embodiment is used for culturing a biological sample 6, the culture medium inside and outside the limiting unit 4 can be fully exchanged, and the biological sample 6 can be ensured to obtain sufficient nutrients, oxygen and carbon dioxide.

The above embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and the protection scope of the present invention is defined by the claims. Various modifications and equivalents of the invention can be made by those skilled in the art within the spirit and scope of the invention, and such modifications and equivalents should also be considered as falling within the scope of the invention.
