Description
Technical field
The utility model belongs near infrared spectrum brain imaging technique field, and especially a kind of cooperation optical fiber cap transfers device.
Background technique
With the development of near infrared light spectral imaging technology, near infrared spectrum starts the inspection applied to mankind's Executive function
It surveys.When brain activity, the neuron on cerebral cortex can make corresponding stimulate the reaction, so that oxyhemoglobin is consumed,
Deoxy-hemoglobin concentrations are caused to increase；It is greater than oxygen consumption since blood flow oxygen-supplying amount increases later, shows oxyhemoglobin
The increase of concentration and the reduction of deoxy-hemoglobin concentrations.Have near infrared band oxyhemoglobin and deoxyhemoglobin
Different absorption spectrums, the light intensity variation through the brain area can deduce that the concentration of oxyhemoglobin and deoxyhemoglobin becomes
Change, realizes brain function activity monitoring.This detection technique usually utilizes near-infrared brain scanner to realize, brain scans instrument
Several dismountable near-infrared probes are equipped with, near-infrared probe is contacted with the scalp of people, is detected near near-infrared probe
Brain activity situation.Due to blocking of the hair to infrared light of people, there is a degree of interference, shadow to near-infrared probe detection
Detection accuracy and stability are rung.
In the prior art, such as the patent " photoelectricity applied to transcranial magnetic stimulation of Patent No. " 201610664804.0 "
The headgear of Collect jointly brain signal ", when near-infrared probe is inserted through hole, the flexibility of through hole bottom is every the ring of light by close red
The extruding of the direction periphery of outer probe, thus into contact with hair push aside, expose and be irradiated to the scalp of near infrared light enough.Again
Such as a kind of patent " detecting head for brain scans " of Patent No. " 201621035724.0 ", also use similar original
Reason, it is up big and down small taper that flexible guiding, which covers shape, and launching fiber and reception light guide bundles are inserted into the flexible guiding set
It in pilot hole, launching fiber and receives light guide bundles and forces flexible guiding set expansion, and then separate hair, so that launching fiber and connecing
Light guide bundles are received directly to contact with scalp.
This two technologies, it is higher to the operation level requirement of personnel, need first to be worn on the head instrument, be inserted into probe or
Optical fiber is able to push hair aside using the extruded deformation of flexible material.This mode of operation trouble is complicated, generally requires detection people
Member has higher operation horizontal, also fails to the case where successfully pushing hair aside after being frequently present of insertion probe.
Summary of the invention
It is a kind of easy to operate in order to invent, it can effectively push the device of hair near near-infrared probe aside, the utility model mentions
A kind of cooperation optical fiber cap has been supplied to transfer device, specific technical solution is as follows.
A kind of cooperation optical fiber cap transfers device, which is characterized in that including hollow cylinder shell, in the housing side
Portion or top surface are equipped with annular groove, and handle protrudes into inside from the hull outside by the annular groove, the shell it is interior by up to
The rotation section of the spring and circular ring shape that mutually abut using pressure is had, the handle is connect with rotation section；The spring position
Above the rotation section；The housing bottom run through be equipped with the first groove, several shifting blocks pass through first groove with it is described

The above-mentioned annular groove for transfering device can be located at housing top surface, can also be located at the upper half of housing side.Make
Used time, brain scans instrument is worn on the head, be distributed on instrument it is several it is above-mentioned transfer device, the shifting block of device is bonded with scalp,
Under the effect of spring certain pressure, shifting block is fitted closely with scalp, is avoided generating gap, also be can guarantee and stir hair.By optical fiber
Or near-infrared probe insertion among the shell of device.Rotational handle drives rotation section and shifting block movement, to realize quickly high
It transfers to effect, operates very simple.
Preferably, first groove is circular ring shape, rotates the handle and drives the rotation section and shifting block along described
The rotation of first groove.It is rotated by shifting block close to scalp, completes hair and stir.
Preferably, first groove is for linear and in the radially even distribution of housing bottom surface, the rotation section following table
Face is uniformly provided with several second grooves, and has angle between first groove and the second groove；First groove and
The quantity of two grooves is identical as the shifting block；The shifting block passes through first groove and is pressed into second groove；To turn round
Moving the handle drives the shifting block flexible along the first groove.Since the first groove is radial distribution, the second groove and first recessed
There is angle between slot, therefore under the common guidance of the first groove and the second groove, when rotational handle, rotation section rotation, shifting block
It is not rotated with the second groove, but along the first groove, it radially outward stretches from housing bottom surface center, thus by below device
Hair is pushed aside.
It is highly preferred that the shifting block isThe initial position of shape, the end of the shifting block is located in the housing bottom surface
At the heart.When shifting block linear and when being located at immediately below shell, since housing bottom surface centre distance shifting block is there are also certain distance, will dial
Head is arranged toShape, converge in the end of all shifting blocks at housing bottom surface center, radially outward when rotational handle
It scatters, effect of breaking out is more preferable.
Preferably, the shifting block terminal horizontal is equipped with annular groove.The setting of annular groove contacts shifting block with scalp
Position forms inclined-plane, and the hair being attached on scalp is dialled (shovel) and is risen.
Preferably, the shifting block end is equipped with hemisphere jut.Hemisphere jut can prevent shifting block damaged scalp.
It is highly preferred that the hemisphere jut is smooth metal material or silica gel material.
A kind of cooperation optical fiber cap provided by the utility model transfers device, is advantageous in that:
1, by handle drive shifting block rotation in the way of, it is more preferable to make to transfer effect, simple and efficient to handle；
2, it by the optimization of shape and material to shifting block motion profile, shifting block end, further improves and transfers effect.
