Problems solved by technology

[0013] However, the above-mentioned automatic flow path switcher 600 needs to be replaced at each inspection, and the used automatic flow path switcher 600 is discarded.
Moreover, the above-mentioned automatic flow path switcher 600 has a large number of parts, and the piston 602 is constituted by a special structure using a double piston structure, so the cost required for the automatic flow path switcher 600 increases.
As a result, there is a problem of high costs for medical institutions and patients

Abstract

A flow path switching apparatus (100) includes a main board (104A), and on a front side of the main board (104A), first pinching means (101) for deforming tube wall of a first branch tube (3004), main pinching means (102) for deforming tube wall of a second main tube (3006) and second pinching means (103) for deforming tube wall of a second branch tube (3008) are provided. This structure provides a flow path switching apparatus allowing simplification of a structure of a contrast medium introducing tube that is discarded after it is used for introducing the contrast medium, and a contrast medium introducing tube to be used with the apparatus is also provided.

Description

technical field [0001] The present invention relates to a flow channel switching device and a tube for injecting contrast medium used in the device. Background technique [0002] In recent years, many devices for checking human body functions have been developed in the medical field. One of them is angiography using an angiography apparatus for diagnosing functions of the brain, circulatory organs, etc. of a human body. In such angiography, a contrast medium in a syringe attached to an injection head is injected into a patient, and the functions of the brain and circulatory organs, etc. are diagnosed by using X-ray diagnosis of the contrast medium injected into the patient. [0003] For example, in cardiac angiographic examinations, when aspirating a contrast medium into a syringe and monitoring a patient's blood pressure, etc., it is necessary to switch the flow path of the contrast medium in the contrast medium injection tube provided between the syringe and the patient. ...
