Technical Field
The utility model relates to an auxiliary device for nuclear magnetic resonance examination, in particular to a negative pressure fixing examination pad for medical cardiac magnetic resonance examination.
Background
The Cardiac Magnetic Resonance (CMR) is a noninvasive and noninvasive imaging examination method, has high soft tissue resolution, high spatial and temporal resolution, large scanning visual field and no ionizing radiation, can perform imaging of any plane, can evaluate the form, the function and the myocardial activity of the heart in one imaging examination, and has high measurement accuracy and good repeatability. In recent years, the CMR is rapidly developed and increasingly widely applied clinically, and the CMR is a routine inspection method for cardiovascular diseases in European and American countries at present. The time for completing the one-time CMR examination is 40-60 minutes, an examiner needs to perform examination in coordination with respiratory motion under the condition that the body is kept as immobile as possible, and the body positions of a patient suspected of ischemic cardiomyopathy before and after the two examinations are in the same position when the patient performs motion load induction examination. The main solution to the above problems in the current clinical CMR application: the air cushion or the spongy cushion is used for fixing the position of the examiner in CMR imaging as far as possible, but the CMR examination time is long, so that the examiner can hardly avoid the phenomenon that the body position of the examiner is changed autonomously due to the fact that the examiner lies on an MRI examination bed for a long time, and the like, and the artifact of CMR scanning diagnosis is caused. The inconsistency of the CMR two examination positions for a patient induced by motion stress affects the image quality and the clinical diagnostic efficacy of ischemic cardiomyopathy.

the utility model discloses a medical negative pressure fixing examination pad for cardiac magnetic resonance examination, which comprises a flexible shell; a granular solid is arranged in the flexible shell; one end of the flexible shell is provided with an air charging and discharging port; the inflation and deflation port is connected with the air pump through a connecting air pipe. The granular solid is a medical soft granular solid. And the air charging and discharging port is provided with an air connector. The air pump can be used for inflating and exhausting air in the flexible shell.
The utility model discloses a fixed inspection pad of medical heart magnetic resonance inspection negative pressure has and can be fixed in the patient through bleeding in the inspection pad and can maintain comparatively permanent time with patient's bodily form especially need the patient at the same position of secondary inspection can keep advantages such as fixed of position. For example, a patient with clinically unstable angina pectoris judges whether myocardial ischemia exists, and is evaluated after the occurrence of myocardial ischemia is induced by using a motion load mode in the existing cardiac magnetic resonance examination process, namely, after the patient firstly performs routine cardiac magnetic resonance scanning for about 30 minutes, moves for 5 minutes from a magnetic resonance examination couch, and returns to the examination couch again to perform cardiac magnetic resonance examination, at the moment, the positions of examination on both sides of the patient need to be highly consistent, so that effective analysis and diagnosis can be performed.

Detailed Description
Referring to fig. 1-5, the negative pressure fixing examination pad for medical cardiac magnetic resonance examination of the present invention comprises a flexible casing 1; a granular solid 2 is arranged in the flexible shell 1; one end of the flexible shell 1 is provided with an air charging and discharging port 3;
the air charging and discharging port 3 is connected with an air pump 5 through a connecting air pipe 4.
The utility model discloses a medical heart magnetic resonance examination negative pressure fixed examination pad, its length is 190cm-220cm, and the width is 60-90cm, and thickness is 8-15cm, can with common MRI inspection bed phase-match.
The flexible housing 1 is a transparent housing.
The granular solid 2 is a medical granular solid.
The granular solid 2 is a soft granular solid.
And an air joint is arranged on the air charging and discharging port 3.
And a reticular filtering device is arranged on one side of the gas joint close to the granular solid. The mesh size of the mesh filter unit is about half of the size of the granular solid, so that the granular solid is prevented from being sucked into the connecting air pipe during air suction.
And a plurality of connecting belts are respectively arranged on two sides of the flexible shell.
The connecting bands on two sides of the flexible shell are arranged in a one-to-one correspondence mode, and two opposite connecting bands can be connected together, so that the examination cushion is fixed on the nuclear magnetic resonance examination bed.
As shown in fig. 3, the lower surface of the flexible casing is provided with a plurality of magic tapes 6.
The flexible shell is tightly attached to the upper surface of the nuclear magnetic resonance examination bed through the magic tape.
An opening part is arranged at one end of the flexible shell, and a sealing zipper is arranged at the opening part.
The granular solid in the flexible shell can be poured out at any time and transferred into new granular solid through the sealing zipper. Thereby enabling the operator to easily replace the granular solid.
As shown in figures 1-3, when in use, the negative pressure fixing examining pad for medical cardiac magnetic resonance examination of the utility model is arranged on an MRI examining table. The patient lies on the negative pressure fixed examination pad for medical cardiac magnetic resonance examination of the utility model, as shown in fig. 4-5. A separation wall 7 is arranged between the doctor observation room and the monitoring room. Connecting pipe 4 passes through the division wall, and the one end of connecting pipe 4 is connected on inflation and deflation port 3, and the other end of connecting pipe 4 is connected on air pump 5.
As shown in fig. 4-5, when the patient lies down and the position is stable, the examining doctor turns on the air pump in the observing chamber of the doctor to pump out the air in the negative pressure fixing examining pad for the medical cardiac magnetic resonance examination. At the moment, the flexible shell contracts to tightly wrap part of the body of the patient, and a human-shaped groove for wrapping the patient is formed on the medical heart magnetic resonance examination negative pressure fixing examination pad. When the first examination of the patient is finished, the patient can get out of bed for activity. At this time, the human-shaped groove on the negative pressure fixed examination cushion for medical cardiac magnetic resonance examination is kept unchanged, and the position on the examination bed is also unchanged. At the second examination, the patient can lie in the position of the humanoid recess, ensuring that it is exactly the same as the first examination position. Therefore, the problem that the inconsistency of the CMR two-time examination positions of the patient induced by the motion load affects the image quality and the efficiency of clinically diagnosing the ischemic cardiomyopathy is solved.
In practical application, the flexible casing 1 can be divided into two or more mutually unvented parts, and the parts are connected with each other to form an examination pad with the total length of 190cm-220cm, the width of 60 cm-90 cm and the thickness of 8 cm-15 cm, which can be matched with a common MRI examination bed.
