Abstract

(57) [Summary] [Purpose] To carry out the entire process from formalin immersion to dehydration embedding while storing the collected biological tissue pieces. [Structure] A holding part 2 made of a water-permeable thin film such as Japanese paper is attached to the space of the frame piece 1 which overlaps when folded in half, and the frame piece 1
A locking portion is provided at a symmetrical position. [Effect] Easily performs integrated processing from formalin immersion to dehydration embedding. Workers do not inhale formalin vapor and do not pose a health risk. There is no chance of biological tissue pieces being mixed up or lost during the processing process, and serious human errors are not made.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a storage container for biological tissue pieces.

0002

[Conventional technology]

For example, a biological tissue piece (mucosal membrane) to be examined with a gastrocamera is collected and soaked in formalin. Then, at the time of examination, remove the biological tissue piece from the bottle using tweezers and place it on a mesh. The specimens are then stored in a plastic bag, followed by dehydration and embedding, followed by paraffin embedding.

0003 A piece of living tissue that has become a lump is sliced into 4μ pieces using a microtome. Paste it on a glass slide and perform HE staining.

0004 HE-stained microscopic specimens are examined under a microscope to diagnose cancer cells, tumors, ulcers, etc. ing.

[0005]

[Problem that the idea aims to solve]

It is necessary to prepare numerous bottles to store the large number of collected biological tissue pieces. Ru. In other words, it is necessary to put numbers corresponding to each part of the stomach on the bottles and store them in separate bottles. Ru.

[0006] In addition, it is not easy to find and remove small pieces of biological tissue from the bottle with tweezers. At this time, formalin vapor is inhaled, which may be harmful to health.

[0007] Also, the process of taking out the collected biological tissue piece from the bottle, the process of taking out the biological tissue piece taken out from the bottle. The process of storing living tissue pieces in a mesh bag, and dehydrating and embedding the biological tissue pieces in the mesh bag. In each section of the process, tissue pieces are mixed up or lost. It is easy to make human errors, especially when there is a mix-up. This is extremely dangerous, and human error like this is absolutely unacceptable. Not done.

[0008]

[Means to solve the problem]

When folded in half, a water-permeable thin film such as washi paper is attached to the space between the overlapping frame pieces and held together. A locking recess and a movable locking tongue are provided at symmetrical positions on the frame piece. A storage container for biological tissue pieces according to the present invention is formed.

[0009] The biological tissue piece stored in the holding part is fixed by immersing it in formalin, and is then removed. The series of steps up to water embedding treatment is performed while the biological tissue piece remains in the container. The porpose is to do.

0010

[Effect]

The collected biological tissue piece is placed on the holding part that is integrated with the unfolded frame piece.

[0011] Fold the frame piece and the holding part in half, overlap them, and engage the locking tongue piece in the locking recess. Accordingly, the living tissue piece is wrapped and stored in the holding part.

0012

【Example】

An embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, it has flexibility, Moreover, when folded in half at the crease 1a, a water-permeable material such as Japanese paper is placed in the space of the overlapping rectangular frame pieces 1. The holding portion 2 is formed by integrally pasting the thin film.

[0013] At a symmetrical position of the frame piece 1, one side is cut into a concave shape to form a locking recess 3. Cut the other side until it reaches the middle of frame piece 1, and make a cut parallel to frame piece 1 on the cut side. A fold line 4a is provided to form a locking tongue piece 4 that can be raised and lowered.

[0014] As shown in Figures 2 and 3, fold frame piece 1 in half from crease 1a and hold frame piece 1 and The parts 2 are overlapped and the locking tongue piece 4 is bent to engage and fix in the locking recess 3. 5 is the collected biological tissue piece.

[0015]

[Effect of the idea]

Since the present invention is constructed in this manner, the collected biological tissue piece 5 is immediately held in Japanese paper, etc. It can be easily wrapped by placing it on section 2 and folding it in half together with frame piece 1. It was fixed by immersion in formalin, and then dehydrated and embedded. Because a series of steps can be performed in the There is no need to prepare many bottles for storage, and you can use tweezers from each bottle. It is harmful to health because it does not require inhaling formalin vapor to extract it. There is no risk.

[0016] Furthermore, in order to consistently perform the processing process from wrapping the biological tissue piece 5 to the dehydration embedding process. Therefore, biological tissue pieces may be mixed up due to human error during the many processing steps as in the past. There is no risk of losing or losing the information, and there is little risk of serious misdiagnosis. In addition, conventionally, dehydration and embedding were performed in a mesh bag; In contrast to the labor-intensive task of inserting a living tissue piece, the living tissue piece 5 is placed on the holding part 2. The frame piece 1 can be reliably and easily stored by a simple operation of folding the frame piece 1 in half.

[0017] In addition, the present invention can be applied to biological tissue pieces of laboratory animals, and can also be applied to biological tissue pieces such as plant growth points. It is also suitable for making microscopic specimens of cells.
