Description

Technical Field

[0001] The utility model relates to a head cap device for collecting cerebral blood oxygen signals. Background Art

[0002] CN215078691U A head cap and brain function imaging system provides a head cap and a brain function imaging system, the head cap includes a cap body, an adsorbent, a ventilation duct and a negative pressure generating component. The negative pressure generating component is connected to the ventilation duct, and is configured to generate high-speed flowing gas, adsorb the gas in the air vent into the ventilation duct, so that a negative pressure cavity is formed in the air vent to absorb the adsorbent toward the head, so that the probe or electrode installed on the cap body can be firmly adsorbed on the area to be measured on the head, so that the head cap can effectively improve the anti-motion interference ability in the process of physiological signal acquisition, that is, it can reduce the motion artifacts generated in the process of physiological signal acquisition, and high-quality physiological signals can be obtained without using a complex calculation post-processing method. However, the technical problem is that it has poor versatility, and due to the negative pressure, it is uncomfortable to wear and there is noise.

[0003] Traditional blood oxygen collection devices are fixed head cap designs. The probes arranged in fixed positions for different head shapes cannot collect brain motor area signals very well, and are easily disturbed by hair and easily deviated during movement. The design of the utility model can more flexibly adjust the brain motor function area close to different head shapes. The open design is more convenient to adjust hair interference, and the three-dimensional strap fixation reduces the cheap interference caused by movement. CN217365830U is a near-infrared brain imaging head cap that resists movement interference, and it does not solve the above technical problems. Utility Model Content

[0032] like Figure 1-5 As shown, the headgear device for collecting cerebral blood oxygen signal of this embodiment includes a support frame 1 with a ring shape and a hollow inner cavity 4, which is set according to the size of the human head, generally slightly larger than the head circumference, and made of light and breathable material; a top main board 3 is arranged on the support frame 1, which is used to contact the top of the head for detection and collection; a top strap 2 is connected between the top main board 3 and the support frame 1; it can be a rigid strip or a flexible strip. It can be adjusted according to the height of the head, and the adjustment is convenient and flexible.

[0033] The support frame 1 includes a headband 6, which is slightly larger than the circumference of a person's head to avoid clamping the head; a plurality of fitting sheets 13 are distributed on the headband 6. As an innovative point, the flexible fitting sheets are used to fit the head to avoid falling and to achieve a flexible and comfortable fit;

[0034] In order to increase its flexibility and facilitate bonding, process slots 15 are provided between adjacent bonding sheets 13 so as to separate them from each other;

[0035] The upper end of the fitting sheet 13 is inclined toward the inside of the hollow inner cavity 4 of the support frame 1, so as to avoid sliding down due to the large headband portion 6, and at the same time has a contoured curvature to achieve better fitting;

[0036] As an improvement, in order to achieve better fitting, based on its own inclination, a serial hole 16 is provided on the fitting sheet 13 in the circumferential direction; a connecting rope 17 is connected in series in the serial hole 16; and the end of the connecting rope 17 is connected to a locking portion 18. The connecting rope passes through the serial hole and is finally tightened and fixed by knotting or tightening the rope. In this way, the hollow inner cavity 4 is gathered to better fit the head. The locking portion 18 can be a manual knot or a rope tightener.

[0037] The bonding sheet 13 is provided with process openings 14 to increase air permeability, reduce weight, facilitate observation, and increase its elasticity.

[0038] When the fitting sheet 13 adopts a composite structure or has a rubber layer alone, it is convenient to inflate the inner cavity, so that the fitting sheet 13 is inflated. An inflation nozzle 19 is provided on the fitting sheet 13. Through inflation, the fitting sheet is gathered inwards to better fit the head.

[0039] Therefore, a gasket that contacts the head is attached to the inner side of the bonding sheet 13, and the gasket prevents the bonding sheet 13 from deforming and causing discomfort when it contacts the head.

[0040] As a conventional technique, snap fasteners A5 are provided on a plurality of spaced apart bonding sheets 13 .

[0041] The lower end of the top strap 2 is connected to the buckle A5 to achieve connection.

[0042] As a further improvement, guide grooves 7 are provided on both sides of the headband portion 6 along the circumferential direction; the guide grooves 7 are equipped with buckle portions B9.

[0043] A guide pin 8 is connected to the back of the buckle part B9, a through hole is provided in the middle and a locking nut 10 is provided on the front; this can prevent the strap from being lost and is convenient for adjustment.

[0044] The corresponding ends of the corresponding straps 11 are passed through the through holes and locked by the lock nuts 10. The guide pins 8 move in the guide grooves 7.

[0045] A contoured rubber pad 12 is provided in the middle of the strap 11 to increase comfort.

[0046] The utility model is easy to adjust, firmly fastened, adjustable in length and flexible in use.

[0047] In specific use, according to the approximate size and shape of the head circumference, a matching support frame 1 is selected; the headband part 6 is worn on the head, and the corresponding gasket is selected on the inner side of the bonding sheet 13 according to the gap, and the connecting rope 17 is connected in series in the serial hole 16. The locking part 18 is fixed by knotting or other means, so that the bonding sheet 13 wraps around the top of the head like a lotus; the top strap 2 is used to bind at the buckle A5, so that the monitoring component of the top main board 3 contacts the required position such as the top of the head, and the hollow inner cavity 4 is used to accommodate the head. By passing the strap 11 through the buckle part B9 and locking it through the locking nut 10, the position adjustment of the guide pin 8 is facilitated by the guide groove part 7 to meet the requirements of different mandibular positions, the contoured rubber pad 12 realizes flexible contact, and the bonding sheet is conveniently aggregated through the process slot 15. When close pressure contact is required, the corresponding bonding sheet can be inflated through the inflation nozzle 19, and it is easy to adjust.

[0048] The present invention is fully described for a clearer disclosure, and the prior art will not be listed one by one.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it; although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some of the technical features therein with equivalents; it is obvious for those skilled in the art to combine multiple technical solutions of the utility model. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the utility model.
