Detailed description of the invention

For patient when magnetic resonance abdominal examination, the situation that the abdominal part fluctuating frequency that causes owing to respiratory frequency is inconsistent is uneven, the thinking adopted in this programme is, utilize the mode of passive compressing, the stomach wall making patient is cyclically subjected to compressing, the fluctuating making stomach wall gradually is consistent with compressing frequency, affects respiratory frequency with the adjustment of this passive type, reaches to adjust the purpose of respiratory frequency. Meanwhile, pressing process can certain time as requested, to meet the requirement that needs of patients in checking process is felt suffocated.

Overall plan of the present utility model is as shown in Figure 1, a kind of special breathing regulator 8 of magnetic resonance abdominal examination, including the ring towel 3 being circumferentially positioned at patient's abdominal part, the inner surface distribution of ring towel 3 has multiple air bag 2, air bag 2 connects an inflation regulating box 6 can inflated in air bag 2 by gas tube 5, and inflation regulating box 6 is connected to an actuator 8 with display screen 10.

The ring towel 3 that abdominal part is arranged is a stiff soft towel body, and its effect is that air bag 2 is fixed. It is set for non-elastic structure, is be the direction towards patient's stomach wall to make the compressing direction of air bag 2 when air bag 2 is inflated. The inner surface of ring towel 3 is the finger ring towel 3 one side near patient's stomach wall, in order to oppress the stomach wall of patient, is provided with multiple air bag 2. When air bag 2 will expand after inflating, after expansion, extrude stomach wall; Periodically expand by controlling air bag 2, it is possible to affected the fluctuating frequency of patient's stomach wall by air bag 2.It is interconnected by connecting tube 4 between multiple air bags 2. The inflation of air bag 2 controls by inflating regulating box 6, is provided with aerating device; The actuator 8 inflating regulating box 6 connection then controls the duty of aerating device.

This programme is arranged on ring towel 3 part-structure with patient, all adopt low density material to make, do not contain the materials such as metal, inflate regulating box 6 and be then arranged far from the position of magnetic resonance scanner, therefore ring towel 3 is arranged on after with patient, scanning result will not be produced impact.

Ring towel 3 is the structure that can launch, ring towel 3 is deployable for strip structure, the end of ring towel 3 is provided with and ring towel 3 can be fixed as ring-type to be circumferentially positioned at the thread gluing 1 of patient's abdominal part, during use first by the inner side of ring towel 3 near patient's abdominal part, then ring towel 3 is wrapped on patient's abdominal part, utilizes thread gluing 1 to be fixed.

Air bag 2 in this programme can generally inflation/deflation formula structure, it would however also be possible to employ following alternative:

Air bag 2 is double-decker, and including the first air bag and the second air bag, wherein the first air bag is the enclosed construction that inside is filled with gas, is adjacent to ring towel 3 and arranges; Second air bag be can inflation/deflation formula structure, the second air bag connects described gas tube 5.

Air bag 2 near ring towel 3 is the first air bag, is wherein filled with the gas of fixed volume; Second air bag has charge and discharge QI KOU, utilizes gas tube 5 to carry out inflation/deflation. The cause so arranged is, if air bag 2 generally inflation/deflation structure, then fills each time, exit needs longer time, therefore this dual air bag 2 structure is set, store a part of gas by the first air bag in advance, reduce each charge and discharge tolerance, it is simple to regulate process.

Inflation regulating box 6 is provided with aerating device, as shown in Figures 2 and 3, being provided with elastic inflatable ball 11 in inflation regulating box 6, inflatable ball 11 is clamped between a pair pressing plate 14, the end of two pressing plates 14 is hinged in same rotating shaft 12, is provided with spring 13 between two pressing plates 14; Being provided with motor 15 between each pressing plate 14 and inflation regulating box 6 inwall, motor 15 connects described actuator 8 by wire 7.

The principle of inflation/deflation is, inflatable ball 11 storage inside has the gas of certain volume. Motor 15 is linear electric motors 15, when motor 15 operates, promotes two pressing plate 14 move toward one another, pressing plate 14 athletic meeting extruding inflatable ball 11, its internal gas is flowed to air bag 2 by gas tube 5 by inflatable ball 11, expands compressing patient's abdominal part after air bag 2 inflation, and meanwhile accumulation of energy oppressed by spring 13. After motor 15 stop motion regaining output shaft, two pressing plates 14 are supportted back original position by spring 13, and under the effect of elastic-restoring force, inflatable ball 11 restores to the original state, and plays decompressing effect.

If needs of patients is felt suffocated, then after gas is squeezed in air bag 2 by inflatable ball 11, keeping the position certain time of motor 15, now keep inflated condition in air bag 2, can certain time patient's stomach wall be oppressed, assisting patients holds one's breath.

Being provided with controller and battery in actuator 8, battery is motor 15 and controller is powered; Being provided with button 9 on actuator 8, button 9, display screen 10 are connected with controller.

The control of motor 15 in this programme, can be regulated by the program set in advance. During setting program, motor 15 is made periodically to operate, so that air bag 2 periodically expands, shrinks. These functions and setting can be arranged by the case on adjustment ball. Automatic mode can certainly be set to, directly control the convergent-divergent of air bag 2 by periodically pressing keys 9.Display screen 10 can reality current air bag 2 contraction frequency and working time, the information such as duration of feeling suffocated, it is simple to doctor regulates.
