Abstract

A test device includes a housing and a lid. The housing encloses an internal space, has a hole supporting a container accommodating liquid, and includes a perforation/incision part. The lid covers a hole-formed part of the housing. The housing and/or the lid includes a guide that guides the housing and the lid, so that the lid can migrate from the first position to the second position while covering the hole-formed part of the housing. In the first position, the lid covers the hole-formed part of the housing and the container and the container is not incised. During the migration of the lid from the first position to the second position, the container is pushed toward the perforation/incision part by the lid, and the container is incised to leak liquid into the internal space.

Claims13

Dependent claims

A test device comprising a housing and a lid mounted on the housing,

wherein the housing comprises:
at least one hole;
a hole-formed part where the at least one hole is formed;
an internal space enclosed in the housing where chromatography using a chromatography support is carried out;
and
a perforation/incision pail provided in the internal space,
wherein the internal space is communicated with the outside of the housing through the at least one hole, allowing at least one container accommodating a liquid used for chromatography to be inserted and supported,
wherein the perforation/incision part perforates or incises the container to leak the liquid from the container into the internal space,
wherein at least either one of the housing or the lid comprises a guide that guides the lid to the housing in a manner such that the lid can migrate from a first position to a second position while covering the hole-formed part of the housing with the lid and supporting the container through the at least one hole,
wherein the first position is a position where the lid covers the hole-formed part and an outer portion of the container protruded toward the lid through the at least one hole and the container is not perforated or incised at the perforation/incision part,
wherein a distance between the hole-formed part and a part of the lid facing the hole-formed part at the first position is larger than the distance at the second position, and
wherein, while the lid is allowed to migrate from the first position to the second position, the housing and the lid are guided by the guide in a manner such that the part of the lid abuts against an end of the outer portion of the container, the container is pushed toward the perforation/incision part, and the container is perforated or incised at the perforation/incision part to leak the liquid into the internal space.
