Embodiment Construction

[0059] exist figure 1 The perforated plate 11 shown in has a base body 12 which forms the substantially flat upper side 3 of the perforated plate 11 . A plurality of recesses 14 are formed in the upper side 13 , each having a rectangular, horizontal overall dimension. The grooves 14 are arranged in eight rows A to H and six columns 1 to 6 . An annular channel 15 is formed on the bottom of each groove 14 , which is delimited on its inner circumference by a surrounding wall 16 . On the outer periphery of the annular channel, the annular channel 15 is delimited in sections by a longitudinal wall 17 and in sections by a wall 18 which delimits the corresponding groove on the long side of the groove, so Said wall transitions upwards into a transverse wall 19 which delimits the respective groove 14 on its narrow side. In the surrounding wall 16 , a blind hole 20 is formed in each groove 14 , out of which two retaining fingers 21 protrude upwards. The horizontal periphery of the s...

Abstract

The invention relates to a perforated plate (11) comprising a plate main body (12) and at least one depression (14) in an upper side (13) of the plate main body (12). An upwardly open annular channel(15) is formed in the at least one depression (14), which is delimited on the inner circumference thereof via a closed circumferential wall (16). A horizontal outer circumference of the circumferential wall (16) decreases from bottom to top up to an upper edge (22) of the circumferential wall (16). Within the horizontal outer circumference of the circumferential wall (16) on the upper edge (22), at least two retaining elements (24) are connected upwardly to the upper edge (22) of the circumferential wall (16). The at least two retaining elements (24) are at a free horizontal distance (28) to one another, and at least one of the at least two retaining elements (24) is supported elastically on the plate main body (12) in the horizontal direction.

Description

technical field [0001] The invention relates to an orifice plate having a plate body and at least one recess in the upper side of the plate body, wherein an upwardly open annular channel is formed in the recess, in which the annular channel Peripherally bounded by a surrounding wall. [0002] In particular, the invention relates to a well plate with a plurality of such grooves for the production and study of tissues, such as cardiac muscle tissue and skeletal muscle tissue, produced artificially by so-called tissue engineering. and connective tissue, wherein the term ring is to be understood in such a way that the corresponding tissue forms a closed loop or knot, but it is not necessary that the loop or knot have a specific geometric shape or even be perfectly circular. [0003] Furthermore, the invention relates to the use of such an orifice, in particular in the context of the production and investigation of rings composed of artificial cardiac and skeletal muscle tissue. ...
