Liquid delivery device based on magnetic resonance detection

Abstract

The invention discloses a liquid delivery device based on magnetic resonance detection. The device comprises liquid storage bottles, peristaltic pumps, a liquid delivery control part, and a fixed intraoral liquid delivery part capable of being fixedly arranged in an oral cavity, the liquid storage bottles are connected with liquid inlets of the peristaltic pumps, liquid outlets of the peristalticpumps are connected with the fixed intraoral liquid delivery part, the peristaltic pumps are also connected with the liquid delivery control part, and the liquid delivery control part is used for controlling a work process of the peristaltic pumps. According to the device, the special fixed intraoral liquid delivery part is provided to achieve the maximum fixing feeling and comfort in the oral cavity, different taste stimulation programs can be set in the liquid delivery control part to control kind numbers, delivery speeds and sequences of different kinds of taste liquid more flexibly, and the control of taste stimulation is more accurate compared with manual operation.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a liquid delivery device based on magnetic resonance detection. Background technique [0002] With the advancement of modern technology and medicine, functional magnetic resonance has become an important means for human beings to explore the functional areas of the brain, and it is widely used in the fields of neurosurgery, neurology, pharmacology, and psychiatry. Functional magnetic resonance imaging has the characteristics of non-destructive, non-radioactive, and repeatability, so that it has great potential in psychiatric research, and can longitudinally track and observe the pathogenesis and development of mental diseases, such as schizophrenia (Schizophrenia), depression (Depression), children's autism (Autism), children's attention deficit hyperactivity disorder, etc. The evaluation of taste perception based on magnetic resonance technology can better understand the fe...

AI Technical Summary

Problems solved by technology

[0004] (1) The receiver used to deliver the experimental liquid to the oral cavity is easy to squeeze the taste buds after being manually placed in the oral cavity, and the resulting tactile stimulation interferes with the taste test process and affects the accuracy of the test results;

[0005] (2) The flow rate of the experimental liquid cannot be well controlled, making it easy to cause discomfort to the experimenter after the experimental liquid is delivered into the mouth, resulting in poor experience for the testee during the experiment
