Auxiliary fixing device for magnetic resonance examination of infant

Abstract

The invention discloses an auxiliary fixing device for magnetic resonance examination of an infant , which relates to the technical field of medical equipment. The device is characterized in that the device comprises a first wrapping piece, a second wrapping piece, a third wrapping piece, a pillow body, an inflation valve, a first binding belt and a second binding belt, wherein two groups of binding belts are arranged on the outer side wall of the pillow body at intervals; the inner wall faces of the first wrapping piece, the second wrapping piece and the third wrapping piece are all detachably connected with heat preservation mechanisms. According to the device, the first wrapping piece, the second wrapping piece, the third wrapping piece and the pillow body are internally inflated so that the device can be tightly attached to an infant to be wrapped and fixed, the infant can be conveniently wrapped with a sense of safety, the infant is not prone to being squeezed, the comfort of the infant wrapped by the wrapping body can be improved, magnetic resonance examination of the infant can be quietly completed, the magnetic resonance examination effect is prevented from being affected by infant crying or abnormal movement, and the infant magnetic resonance examination quality is improved. Meanwhile, the situation that adverse reactions are easily generated when a sedative is adopted for auxiliary inspection at present can be avoided.

Description

technical field [0001] The invention relates to the technical field of medical equipment, more specifically, it relates to an auxiliary fixing device for magnetic resonance examination of infants. Background technique [0002] Magnetic resonance imaging (MRI) is a high-tech product that performs imaging based on the resonance characteristics of the magnetic nucleus (hydrogen nucleus) of the organism in a static magnetic field. After the human body enters the magnetic field, a radio frequency pulse of a certain frequency is applied to the main magnetic field, and the excited protons (hydrogen nuclei) in the human body transition from a low-energy state to a high-energy state, that is, nuclear magnetic resonance occurs. By measuring the transverse magnetization vector during the relaxation process of protons transitioning from a low-energy state to a high-energy state, the NMR signals of biological tissues can be obtained. Then, after the obtained signal is transformed by Fou...

Problems solved by technology

Although the above method has the advantages of quick onset, good sedative effect, simple administration, low price, and less pain for children, some adverse reactions have also been found in clinical practice, such as chloral hydrate can inhibit respiration and can cause apnea. It also has an inhibitory effect on the myocardium, causing blood pressure to drop, causing damage to the liver and kidneys, etc.
