FIELD: medicine.SUBSTANCE: invention refers to medical equipment and concerns canal openers, especially for canals of a blood hose or container system. The canal represents a hose accommodating a lock element blocking a canal passage. According to the first embodiment, the canal opener for the blood hose or container system has at least one opening device that is mounted so that it applies an external force on the canal whereby the lock element is compressed, and the channel opens. The opening device is contoured in such a manner that the canal can be only inserted into the opening device so that the force applied to the canal has the effect exclusively or at least alternatively in the region wherein the lock element is found. There are provided aids to prevent inserting the canal into the opening device partially only. These aids have a spring mechanism configured so that the canal is either squeezed out from opening device, or squeezed in correctly in the opening device. According to the second embodiment, the opener or the opening device has a processor unit configured so that it shows or induces an actuation of the opening device at the pre-set moments of time, and/or only inducing the actuation when the canal is positioned correctly in the opening device, and/or controls a canal opening process. According to the third embodiment, the opening device has an opening element, and a drive assembly. The opening element or the drive assembly is coupled with a link guide. The drive assembly or the opening element is provided with a rotating or sliding element that is rotated about the link guide when the drive assembly is actuated. The link guide is formed so that relative motion between the rotating or sliding elements and the link guide induces projection or retraction of the opening element.EFFECT: invention simplifies and forces the opening process in a combination with fulfilling high safety and quality standards.23 cl, 18 dwg |
