Description

One kind is used for nuclear magnetic resonance medical treatment detection bed

Technical field

The present invention relates to nuclear magnetic resonance technical field of medical instruments, more particularly to one kind to be used for nuclear magnetic resonance medical treatment detection Bed.

Background technology

In nuclear magnetic resonance medicine diagnostic device, a magnet and an examination couch for carrying circular cavity is generally included. Examination couch, which is responsible for patient being sent to the position that system specifies, to be scanned, it is generally the case that examination couch is needed with both direction On motion, i.e., movement in vertical direction and horizontal motion the sufferer on examination couch could be sent to circular cavity magnet specify Position.In the vertical movement mechanism of movement in vertical direction is realized, by using traditional shear beam structure, pass through angle change To realize the lifting of height.

The shear beam structure used in traditional lifting scheme includes following several structure types：In the first structure type Shear beam structure in, push rod device is arranged vertically upward, so, because push rod device is generally all two-stage hydraulic push rod, In this case the height that sick bed declines is very limited, causes sick bed can not drop to relatively low position, so as to give some action The patient of inconvenience brings great inconvenience；In the shear beam structure of second of structure type, the summit of push rod device is placed On the position at scissors beam center, the other end is fixed on bottom plate, can so be realized the minimum altitude of sick bed and be reduced, but work as After examination couch is reduced to certain altitude, the thrust of push rod device motor can sharply increase, and this requires the power for increasing motor, this Sample can undoubtedly increase cost.

How to solve above-mentioned technical problem is the problem that the present invention faces.
