A kind of probe of near infrared spectrum cerebral function imaging device
Technical field
The present invention relates to medical imaging technology, and in particular to a kind of probe of near infrared spectrum cerebral function imaging device.
Background technology
Near infrared spectrum cerebral function imaging device using safety near infrared light measuring corticocerebral oxygenated blood red eggs
In vain, the variable quantity of deoxyhemoglobin, total hemoglobin concentration is obtaining cerebral function information.
On near infrared emission probe insertion probe holder, the helmet is worn on testee's head, the top touching scalp of probe,
Near infrared light is received probe and is received detection by incident cerebral tissue of popping one's head in.Probe in existing equipment is generally pylindrical,
Its diameter too detailed rules and regulations are easily snapped off, and its diameter is slightly then inconvenient to insert hair and moves inside hair very much, and therefore design needs
Go out a kind of be not easily broken and can facilitate subtract mobile probe in hair.
Content of the invention
The invention provides a kind of probe of near infrared spectrum cerebral function imaging device, is not easily broken and can facilitate in head
Move between sending out.
In order to solve above-mentioned technical problem, the present invention is adopted the following technical scheme that:
A kind of probe of near infrared spectrum cerebral function imaging device, including the fixed seat being embedded on probe holder, the fixed seat sets
There is manhole, the through-hole side wall is opened up, and probe lateral wall arranges convex annular
Rise, the raised embedded groove is coordinated with its gap, and under probe, part radial section is the oval probe oval shaped portion
Short axle two ends arrange Electrostatic Absorption layer, and the Electrostatic Absorption layer connects miniature electrostatic generator, power supply and switch.
Further, the probe side wall arranges 2 symmetrical projections, and the projection is located at fixed seat upper surface.
Further, the fixed seat upper surface, the both sides of projection are respectively provided with limited block.When probe rotates, convex
Block is rotated therewith together, and limited block limits the angle of projection rotation so as to rotate within the specific limits.
Further, the probe holder is silica gel material.
Further, the fixed seat is TPU materials.
Further, the probe is provided with cylindrical hole, cylindrical hole and arranges probe, arranges spring above the probe.
Further, the probe axle center arranges.Infrared optical fiber
End be located at probe bottom and penetrate probe so that infrared optical fiber directly contact scalp.
Further, the probe side arranges vertical guide groove, and the infrared optical fiber passes through guide groove from optical-fibre channel
Link main frame.When spring-compressed, probe drives infrared optical fiber movement, infrared optical fiber to move up and down in guide groove, prevent
Infrared optical fiber is squeezed in housing the effect for affecting spring.
When using, probe holder is worn on the head, under probe, part is moved between hair, by probe after the resistance of hair
Rotate in through hole so that oval major axis facilitates movement of the probe between hair, while probe along the direction of hair
Will not fracture because of meticulous.
The invention has the beneficial effects as follows:Existing probe is improved, be not easily broken and can probe convenient in hair
Between move.

Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings:
A kind of probe of near infrared spectrum cerebral function imaging device, including being embedded in probe holder(1)On fixed seat(2), described solid
Reservation(2)It is provided with manhole(3), the through hole(3)Side wall opens up a toroidal cavity(4), through hole(3)Interior setting probe
(5), probe(5)Lateral wall arranges annular protrusion(6), the projection(6)Embedded groove(4)Coordinate with its gap, probe bottom
Point(7)Radial section is that ellipse, the probe oval shaped portion short axle two ends arrange Electrostatic Absorption layer(71), the electrostatic suction
Attached layer(71)Connect miniature electrostatic generator, power supply and switch.
The probe side wall arranges 2 symmetrical projections(8), the projection(8)It is located at fixed seat(2)Upper surface.
The fixed seat(2)Upper surface, projection(8)Both sides be respectively provided with limited block(9).When probe rotates, convex
Block is rotated therewith together, and limited block limits the angle of projection rotation so as to rotate within the specific limits.
The probe holder is silica gel material.
The fixed seat is TPU materials.
The probe is provided with cylindrical hole, cylindrical hole and arranges probe(10), the probe(10)Top arranges spring.
The probe(10)Axle center arranges optical-fibre channel(11), the optical-fibre channel(11)Interior setting infrared optical fiber(12).
Infrared optical fiber(12)End be located at probe(10)Bottom and penetrate probe so that infrared optical fiber directly contact scalp.
The probe(10)Side arranges vertical guide groove(13), the infrared optical fiber(12)From optical-fibre channel(11)Interior logical
Cross guide groove(13)Link main frame.When spring-compressed, probe drives infrared optical fiber movement, and infrared optical fiber is upper and lower in guide groove
Motion, prevents infrared optical fiber to be squeezed in housing the effect for affecting spring.
Probe holder is worn on the head, under probe, part is moved between hair, by probe after the resistance of hair in through hole
Rotation so that oval major axis facilitates movement of the probe between hair along the direction of hair, while probe will not be because of
Meticulous and fracture, during use, hair can be tied up backward, Electrostatic Absorption layer is attracted each other with hair, makes the length of oval probe
Axle is parallel with hair, it is to avoid broken probe.
Particular embodiments described above, to present invention solves the technical problem that, technical scheme and beneficial effect carry out
Further describe, the be should be understood that specific embodiment that the foregoing is only the present invention is not limited to this
Invention, all any modification, equivalent substitution and improvements that within the spirit and principles in the present invention, is done etc., should be included in this
Within bright protection domain.
