Problems solved by technology

However, except for vision and hearing, the devices used for other basic sensory stimulation are all self-built, and there are very few commercial products. Among them, the taste stimulation device has problems such as difficult to accurately control the amount of liquid and difficult to change the stimulation intensity. It is more difficult to design and manufacture

Embodiment Construction

[0039] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0040] In order to achieve the purpose of the present invention, as Figure 1-3 As shown, in some embodiments of the taste stimulation device of the present invention, it includes: PC control software 101, used to set the stimulation parameters of the stimulation liquid and form corresponding control parameters; data acquisition card 102, used to The control parameters are converted into control commands and sent to the lower computer control module 104. Specifically, the data acquisition card 102 can receive the stimulus sequence designed by the upper computer control software 101, and send it to its digital input / output terminal through a serial port, and the lower computer control The microprocessor of module 104 receives the control command that data acquisition card 102 transmits with the mode of external interrupt, when there is no stim...

Abstract

The invention discloses a taste stimulation device, which comprises: upper computer control software, used to set control parameters; a data acquisition card, used to convert the control parameters into control instructions; a lower computer control module, used to control the opening according to the control instructions The liquid passage stimulates the liquid to flow out and begins to provide taste stimulation to the tester; the flow meter, which is installed on the liquid passage, stimulates the liquid to flow through the flow meter to generate pulse waves, which are sent to the lower computer control module, and the lower computer control module The counting terminal starts to count the pulse waves, and when the count reaches the set value, the lower computer control module closes the liquid passage. Compared with the prior art, the present invention can realize the real-time and quantitative delivery of the stimulation liquid, so that the stimulation liquid can be carried out in an orderly and quantitative manner as required, thereby effectively solving the difficulty in accurate liquid volume described in the prior art. control, difficulty in changing stimulus intensity, etc.

Description

technical field [0001] The invention relates to a sensory system stimulation device in the field of medical instruments, in particular to a taste stimulation device. Background technique [0002] The brain is the most complex substance in nature, and the study of brain function through imaging methods has always been a field of unremitting exploration by scientists. Brain functional imaging first needs to maximize the activation of the target brain functional area, and try to eliminate the interference of irrelevant stimuli, so as to realize the simplification and idealization of functional activities. At the same time, it is necessary to achieve accurate stimulation delivery and brain activation image acquisition Time synchronization, image acquisition can be done by PET, CT, MRI and other instruments. Brain functional imaging stimulation causes human brain functional activities and obtains corresponding information. ) to exert a stimulating effect, it needs to be realize...
