Embodiment Construction

[0014] As discussed above, magnetic resonance (MR) imaging equipment requires a mechanism to quickly break the vacuum to atmosphere in an emergency. In the context of a medical device that may involve a patient, a manual mechanism for breaking this vacuum is required as a backup. Manual methods currently known in the art rely on a vacuum breaking tool that can be attached to the vacuum breaking access point to perform this safety backup in such emergency situations. Specifically, the vacuum breaking tool function opens the MR magnet vacuum vessel to the atmosphere and destroys the thermal properties used to maintain the magnet's super-connection capability, thereby inducing quenching to cause a loss of magnetic field.

[0015] While currently known vacuum breaking tools function when used correctly, the inventors have recognized that the effectiveness of these tools is dependent on the expertise of the MRI facility, field engineers, nearby medical personnel, and technicians tr...

Abstract

The invention discloses a system for rupturing a vacuum in a medical imaging device. The system includes a vacuum plug attached to the medical imaging device and configured to retain a vacuum in the medical imaging device. A puncture tool is configured to puncture the vacuum plug to rupture the vacuum in the medical imaging machine. A puncture tool retainer removably couples the puncture tool to the medical imaging device.

Description

technical field [0001] The present disclosure relates generally to systems for breaking vacuum in medical imaging equipment, and more particularly to point-of-use systems for breaking vacuum in magnetic resonance imaging equipment. Background technique [0002] Certain medical imaging equipment, such as magnetic resonance or MR equipment, require a vacuum for the magnetic components to function. The process of releasing or "quenching" the vacuum after use is complete is usually performed electronically, which disables the magnetic force generated by the medical device. However, it is also necessary to provide a manual backup to quickly quench the vacuum vessel or to destroy the vacuum vessel to quickly disable the magnetic force. Specifically, in emergency situations in which patients, equipment (i.e., oxygen tanks), and / or other persons or objects become trapped within or are otherwise inadvertently attracted magnetically to a medical imaging device, the vacuum must be qui...
