Description

  The present invention relates to a cassette storage container for pathological examination, and more specifically, for storing a cassette containing a specimen such as a collected pathological tissue and immersing it in physiological saline or formalin for transportation, transportation and storage. The present invention relates to a cassette housing container for pathological examination that can reduce the amount of a medical solution such as physiological saline or formalin, is not bulky, can improve work efficiency, and is easy to handle.

  Samples such as pathological tissues removed or collected during surgery or endoscopy are accommodated in, for example, a cassette C in which a lid and a main body are provided with a through hole as shown in FIGS. The formalin is allowed to flow through the through-hole and then fixed, and then the moisture of the specimen is removed with alcohol, degreased with xylene and given affinity with liquid paraffin, and then embedded in paraffin. The whole paraffin is sliced and examined by microscopic observation.

  By the way, in an actual site, the above work is rarely performed continuously at the same site, and the collected specimen is stored in a cassette and placed in a container filled with a medical solution such as physiological saline or formalin. It is typically stored, transported or transported to a laboratory or a separate laboratory, and stored until it is tested.

As such a container, for example, a cylindrical seal formed by detachably attaching a cap-shaped outer lid to the opening of the container body via an inner lid for sealing, and formed inside the inner lid for sealing. There is a watertight container characterized in that at least one annular seal lip having elasticity is provided on the outer periphery of the portion, the seal portion is inserted into the opening, and the seal lip is brought into inner contact with the inner periphery of the opening ( For example, see Patent Document 1).

  However, when one cassette containing one specimen is stored in a watertight container, the cassette storage efficiency is extremely poor. On the other hand, a large number of cassettes are placed in one watertight container in order to increase the cassette storage efficiency. If, for example, the cassettes come into contact with each other and the data such as the subject name may disappear due to the friction between them, the sample may be mistaken and the reliability of the test may be impaired.

  Therefore, in the case of a relatively small sample, it is conceivable to store the sample in each chamber of a cassette provided with a plurality of chambers and store it in a watertight container. However, even in this case, there is a risk that the data such as the subject name disappears and the specimen is mistaken, and the reliability of the test is impaired.

  In addition, as described in Patent Document 1, when the cassette is stored in a watertight container in an inclined state, a large amount of a chemical solution such as physiological saline or formalin for immersing the cassette is inevitably required. Not only will the cost increase, but the weight will also increase, and the height will also increase, making it unstable and prone to falling over, resulting in poor handling. Moreover, since it is easy to fall down, it becomes difficult to stack watertight containers, which may cause troubles in movement, transportation and storage.

Also, the case in which the discharge port of the liquid or air in the upper Symbol annular leg, air and water into the annular leg, so that to contain the liquid such as a chemical solution is equalized inside and outside the annular leg without Therefore, it is possible to prevent troubles such that the container is attracted to the desk or the like and difficult to lift, and conversely, the container is lifted and slid by the liquid and dropped from the desk.

Further, container body or the lid, or if the container body and a lid with a transparent, the state of the cassette or drug which is housed inside can be visually recognized from the outside preferable.

  The cassette storage container for pathological examination of the present invention comprises a container body and a lid that is watertightly attached to the opening of the container body, and a cassette placement section is provided at the bottom of the container body. To do.

The container body and the lid are each made of a material that is not affected by a chemical solution such as physiological saline or formalin. Examples of such materials include resins such as polyesters, polycarbonates, polyacetals, polyolefins such as polyethylene and polypropylene, and glass. However, they are preferably made of resin in terms of light weight, easy handling, and good moldability. Moreover, it is preferable that the container main body and / or the lid is transparent in that the state of the cassette and the medicine accommodated therein can be visually recognized from the outside.
The shape of the container body and the lid is not particularly limited. For example, the shape may be a circle or a rectangle in plan view, but a circle is preferable in that it can be easily watertight by screwing.

A cassette stationary part is provided at the bottom of the container body. The cassette stationary part may be either convex or concave, but the structure is simple.For example, even if the drug leaks out of the stationary part during movement or transportation, the cassette stationary part is recessed in that it easily returns to the stationary part. It is preferable to install. The cassette mounting portion has a shape that is substantially the same as the planar shape of the cassette, but is preferably slightly larger than the cassette in order to facilitate placement and removal of the cassette.
The depth (height) of the cassette mounting portion is not particularly limited, but it is deep enough not to slide even when the cassette is placed, and the upper surface of the cassette does not sink below the upper surface of the bottom of the container body. The depth is preferable. For example, when the thickness of the cassette is about 5 mm, about 2 mm to 5 mm is preferable.

When accommodating a cassette having compartments formed therein, it is preferable that a symbol for distinguishing each compartment is attached to the container body.
The symbol is not particularly limited as long as it is a symbol that can distinguish each chamber, and examples include various geometric patterns such as Arabic numerals, Roman numerals, alphabets, Greek letters, hiragana, katakana, and other triangles and stars.
The position where the symbol is attached is not particularly limited as long as it can be intuitively understood that the symbol and the chamber correspond one-to-one, but in the normal case, the symbol is attached in the vicinity of the chamber. If the entire container is transparent, a symbol may be provided on the back surface (outside) of the bottom of the container body. There are no particular restrictions on the way in which the symbols are provided, and labeling, printing, or engraving (embossing or engraving) may be used, but they can be applied at the same time as molding, or may be caused by chemical erosion or wear due to repeated use. Engraving (concave or convex) is preferable in that it does not disappear.
Further, if necessary, in order to allow a user to write and record a place to which a symbol is attached, the surface can be roughened so that ink or the like can be easily attached.

A position restricting portion for making the direction of the cassette a fixed direction can be provided in the cassette stationary portion. By providing such a position restricting part, even if the cassette jumps out of the cassette mounting part during movement or transportation, it can be repositioned in the original direction, so there is no mistake in the direction. When the cassette has a small chamber, the symbol of the small chamber is not mistaken to reduce the workability of the inspection and the reliability of the inspection is not impaired.
If the said objective is achieved, what is necessary is just to determine a cassette position control part suitably with the shape and structure of the cassette accommodated so that it may mention later.

  It is preferable to provide a pair of finger insertion portions on the cassette mounting portion because the cassette can be grasped and taken out with fingers without using tweezers, and workability is improved.

The depth of the container body itself (height from the bottom of the cassette mounting portion to the opening) is not particularly limited, but if the height of the cassette to be stored is shallower, the lid hits the cassette. The body cannot be attached, and physiological saline, formalin and the like are not easily filled. If it is too deep, not only will it be difficult to place and remove the cassette, but it will also be necessary to store and remove the specimen from the cassette while the cassette is placed on the cassette mounting section. Becomes difficult. Furthermore, the container is bulky and requires a large space for storage, movement and transportation. Therefore, the depth of the container body is preferably about 1.2 to 5 times that of the cassette to be accommodated, and more preferably about 1.5 to 3.0 times.
In addition, the container main body can be made stackable as a taper shape extending toward the opening except for the screwed portion of the opening. Such stacking is advantageous because it is not bulky during movement, transportation or storage.

  Legs for contacting the desk surface can be provided on the bottom rear surface of the container body. Although a leg part is not specifically limited, Three or more granular protrusions, the annular leg part protrudingly provided by the outer periphery vicinity of the container main body 2, etc. can be illustrated.

When an annular leg is adopted as the leg, if the liquid or air such as water or chemicals is sealed in the space surrounded by the bottom of the container body, the annular leg, and the desk surface, the container is adsorbed on the desk surface. On the other hand, the container may be lifted by the liquid and slid on the desk. Therefore, it is preferable to provide a discharge port for extracting the liquid and air from the space.
The number of outlets is not particularly limited, but is usually several, preferably 2-6.

  The lid body is water-tightly attached to the opening of the container main body, but the attachment structure is not particularly limited, and all water-tight structures of ordinary liquid containers can be suitably employed. Specifically, as described in Patent Document 1 (Japanese Patent Laid-Open No. 2001-002112), a structure having a high degree of water tightness using an inner lid having a sealing lip may be used. A simple watertight structure composed of a lid body screwed into the opening of the main body and a sheet-like sealing material can also be employed.

  It is preferable that the container main body and / or the lid is provided with a slip-preventing means so that the container of the present invention does not slide down when stacked. Such sliding prevention means is not particularly limited as long as sliding is prevented at the time of stacking, but for example, when an annular leg or a granular leg is provided on the bottom lower surface of the container body as described above. The annular protrusion can be provided on the lid body on the outer periphery of the annular leg portion or the granular leg portion, that is, the annular protrusion detachably fitted to the annular leg portion or the granular leg portion.
