Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically to an infant headgear. Background Technology

[0002] Currently, functional brain imaging technology is widely used in clinical practice and can be used to study the relationship between brain structural damage and cognitive deficits, providing an important research tool for understanding the brain structural basis of cognitive function. In particular, near-infrared spectroscopy functional brain imaging (FNIRS) utilizes near-infrared light and a multi-channel sensor composed of transmitting and receiving probes. Based on the neural-blood oxygen coupling mechanism, FNIRS can penetrate the skull, detect and image changes in brain activity activation with high temporal resolution, and effectively visualize and quantitatively assess brain function. Electroencephalography (EEG) is a non-invasive detection technique that records the electrical activity of brain nerve cells using electrodes. Neurons in the brain generate tiny electrical signals when active; these signals are captured and amplified by electrodes on the scalp, ultimately transforming into visualized waveforms. This allows for analysis of brain electrical activity in different states and provides a basis for understanding brain health.

[0003] However, in the current technology, when using near-infrared spectroscopy brain functional imaging equipment or EEG equipment to examine certain special users, there are situations where users are uncooperative and it is difficult to obtain effective data. For example, infants and young children are unable to control their movements due to their young age and immature mandible development. Existing detection equipment cannot be well fixed to the head of infants and young children, or it may cause discomfort to the user during the wearing process, thus causing the user to resist using it. This is very inconvenient for medical staff to operate. Utility Model Content

[0004] This application aims to provide an infant headgear to solve the problem in the prior art that the detection device cannot be properly secured to the infant's head, thus making it impossible to collect the required data.

[0005] This utility model provides an infant headgear for mounting EEG electrodes and / or near-infrared detection probes to obtain EEG data and / or blood oxygen data from the infant's head. The headgear includes a headgear body and a headgear fixing device. The headgear body has ear holes on both sides and includes extensions around the ear holes. The headgear fixing device is symmetrically arranged at the extensions on both sides. The headgear fixing device is configured to fasten the headgear body to the infant's head with a variable force direction F of 0° to 90° relative to the infant's body midline M.

[0006] In some embodiments, the headgear fastening device includes a chin rest connected to each extension, wherein the distance between the lower edge of each chin rest and the lower edge of the extension on the same side is not less than the length of the infant's mandible, and the chin rest is configured to provide a variable force direction F to the headgear body with an external force during the detection process, thereby fastening the headgear body to the infant's head.

[0007] In some embodiments, the chin rest is provided with a gripping hole at the end away from the extension, the gripping hole being configured to allow at least one finger to pass through.

[0008] In some embodiments, the chin support is made of an elastic material, and the chin support changes length along the force direction F when the headgear body is fastened to the infant's head, the length change range being at least 1 cm.

[0009] In some embodiments, the first width b1 at the center of the gripping hole on the chin rest is not less than the second width b2 away from the center of the gripping hole.

[0010] In some embodiments, the headgear securing device includes a strap configured to, during detection, provide a force direction F to the headgear body with its own tension, thereby securing the headgear body to the infant's head.

[0011] In some embodiments, the strap is located on the outside of the cap.

[0012] In some embodiments, the straps are disposed around the front edge of the headgear body and extend to the extensions on both sides of the headgear body.

[0013] In some embodiments, the straps are disposed around the rear edge of the headgear body and extend out at extensions on both sides of the headgear body.

[0014] In some embodiments, the headgear body and the headgear fastening device are integrated into one unit.

[0015] Compared with the prior art, the beneficial effects of this utility model embodiment are as follows: By setting the head cap fixing device with a flexible force direction F on the head cap body, this utility model enables the detection equipment to be more flexibly and effectively fastened to the infant's head during the detection process, ensuring that the required data is effectively collected during the acquisition of EEG data and / or blood oxygen data signals. It also significantly reduces the pressure and restraint on the infant's immature mandible and soft chin, thereby improving the infant's compliance during the data collection process. Furthermore, the above-mentioned structural design is reasonable and can effectively assist medical staff in collecting data. Attached Figure Description

[0029] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0030] This invention provides a headgear for infants and toddlers. This headgear can be used in near-infrared spectroscopy brain functional imaging devices and / or electroencephalogram (EEG) devices to install EEG electrodes and / or near-infrared detection probes to obtain EEG data and / or blood oxygenation data from the head of infants and toddlers.

[0031] As shown in Figures 1(a) and 1(b), an infant headgear is displayed on a head model. The infant headgear includes a headgear body 1 and a headgear fixing device 2. The headgear body 1 has ear holes 3 on both sides and includes extensions 4 around the ear holes. It can be understood that the ear holes 3 are symmetrically located on both sides of the headgear body 1 to allow the user's ears to pass through after the headgear is put on. The extensions 4 around the ear holes extend away from the top of the headgear body. After the headgear is put on, without external force, the lower edge of the extensions 4 corresponds to the infant's mandible. The headgear fixing device 2 is symmetrically located at the extensions 4 on both sides. The headgear fixing device 2 is configured to secure the headgear body to the infant's head with a variable force direction F of 0° to 90° relative to the infant's body midline M. During the examination of the infant, the infant's head may move due to the softness and weak support of the neck, or the infant may shake their head and neck while crying. In these scenarios, the headgear fixing device 2 allows users to flexibly adjust the force direction F, enabling the detection device to be more flexibly and effectively secured to the infant's head, ensuring that the required data is effectively collected during the acquisition of EEG and / or blood oxygen data signals; and since the force direction F does not act directly on the infant's chin, it significantly reduces the pressure and constriction on the infant's immature jawbone and soft chin, thereby improving the infant's compliance during the data acquisition process.

[0032] In some embodiments, such as Figure 2 As shown, the headgear fixing device 2 includes a chin support 21 connected to each extension 4. The distance 'a' between the lower edge of each chin support 21 and the lower edge of the extension 4 on the same side is not less than 3 cm. Preferably, the distance 'a' is 3-10 cm. This distance range ensures that, during the testing process, after the infant wears the headgear, the chin support can fit the jawbone length of most infants. Furthermore, the chin support 21 is configured to, during the testing process, provide a force direction F of 0° to 90° relative to the infant's body midline M with an external force, thereby securing the headgear to the infant's head.

[0033] See Figure 3This utility model provides a schematic diagram of the infant headgear in use in one application scenario. The infant's body midline M is positioned as shown. When the headgear is put on the infant for testing, an external force is applied to the chin support 21, which in turn provides a force F to the headgear body 1 to secure it to the infant's head. The headgear body 1 is equipped with EEG electrodes and / or near-infrared detection probes to acquire EEG data and / or blood oxygenation data from the infant's head. To meet different testing needs and adapt the headgear to more scenarios, such as when different brain regions need to be focused on for data acquisition during infant head testing; or when the detection signal in a certain area is poor, the positions of the EEG electrodes and / or near-infrared detection probes need to be adjusted promptly to acquire the required data; or when uncontrollable head movements or crying cause shaking during testing, the positions or contact strength of the EEG electrodes and / or near-infrared detection probes need to be adjusted promptly and flexibly to improve the fit and comfort of the infant while wearing the headgear, thus facilitating the acquisition of the required data. Therefore, in order to collect the required data, the corresponding EEG electrodes and / or near-infrared detection probes for the corresponding brain regions should be attached to the corresponding scalp of the infant as much as possible. At this time, relative to the infant's body midline M, an external force needs to be provided to the chin support 21. The chin support 21 provides a variable force direction F to the head cap body with the external force received, and fastens the head cap body to the infant's head.

[0034] Specifically, as shown in Figure 1(a), under normal circumstances, the infant headgear is used to collect EEG data and / or blood oxygenation data of the entire brain region of the infant's head. This requires the EEG electrodes and / or near-infrared detection probes to be attached to the infant's scalp as much as possible to collect more comprehensive data. At this time, relative to the infant's body midline M, the chin support 21, under external force, provides a force direction F extending along the direction of the infant's mandible to the headgear body 1. The angle α formed by this force direction F relative to the body midline M is preferably in the range of 30° to 60°, which effectively secures the headgear body to the infant's head. When it is necessary to adjust the headgear to collect data from the infant's frontal lobe, the chin support 21, under external force, provides a force direction F' close to 0° to the headgear body 1, thereby securing the headgear body to the infant's head. When it is necessary to adjust the headgear to collect data from the infant's occipital lobe, the angle α formed by this force direction F relative to the infant's body midline M is... Under external force, the chin support 21 provides a force direction F toward the headgear body 1 at a 90° angle, thereby securing the headgear body to the infant's head. Similarly, as shown in Figure 1(b), when the headgear needs to be adjusted to collect data from the left or right temporal lobes or motor areas of the infant's head, the chin support 21 provides a force direction F of 0° to 90° relative to the infant's body midline M, thereby securing the headgear body to the infant's head. For example, when data from the left temporal lobe area of ​​the infant's head needs to be collected, the force direction F can be directed toward the right front of the body at approximately 45°, at which point the force direction F forms an angle of approximately 45° relative to the body midline M. Note that the use of "approximately" or "close to" an angle in this document is intended to indicate a range within ±(5° to 10°) of that angle. This application does not limit the specific angle of the force direction F, as long as the angle is sufficient to secure the headgear body to the infant's head during use.

[0035] This invention incorporates a headgear fixing device with an adjustable force direction F on the headgear body. This allows for more flexible and effective securing of the testing equipment to the infant's head during the testing process, ensuring the effective acquisition of necessary data during EEG and / or blood oxygenation signal acquisition. Furthermore, because the force direction F does not directly act on the infant's chin, it significantly reduces pressure and constriction on the infant's still-developing jawbone and soft chin, thus improving the infant's compliance during the data collection process. The aforementioned structural design is also reasonable and effectively assists medical personnel in data collection.

[0036] In some embodiments, such as Figure 2As shown, a gripping hole 211 is provided at the end of the chin rest 21 away from the extension 4. The gripping hole 211 is configured to allow at least one finger to pass through. The gripping hole 211 provides a gripping area when others grip the chin rest 21, and in particular, allows at least one finger to pass through, facilitating the finger to enter the gripping hole 211 and grasp the chin rest 21. This prevents the chin rest from slipping off the finger during the gripping process, thus preventing the problem of data interruption. This effectively improves the user experience and can effectively assist medical personnel in collecting data. Of course, the aforementioned finger can also be replaced by other objects, such as finger-like models or rod-shaped objects. This application does not specifically limit this, as long as it can pass through the gripping hole and provide force direction to the chin rest.

[0037] Specifically, such as Figure 2 As shown, the first width b1 at the center of the grip hole of the chin rest 21 is not less than the second width b2 away from the center of the grip hole. This arrangement allows the grip hole to accommodate the normal passage of fingers while still retaining an edge portion, and this edge portion can withstand the external force applied to the chin rest, significantly extending the service life of the chin rest.

[0038] Specifically, the chin support 21 is made of an elastic material that is skin-friendly, elastic, and meets Class A standards. This design makes the material more comfortable and reduces discomfort for infants and young children when applied to their heads and faces. When the headgear body 1 is fastened to the infant's head, the chin support 21 changes length along the force direction F. This length change range is at least 1 cm, preferably 1-3 cm. This design ensures a secure fit without excessive pressure on the infant's head, improving the infant's compliance during the collection process. Furthermore, the headgear body 1 is also made of an elastic material and is integrated with the chin support 21, making the material more uniform, easier to manufacture, and more comfortable to wear. Preferably, when the headgear body is fastened to the infant's head, the entire headgear changes length along the force direction, with a length change range of at least 5 cm. This elastic design further enhances the infant's compliance during the collection process.

[0039] During the use of the above-mentioned infant headgear, there may be situations where the infant falls asleep or whose movements are relatively easy to control. Therefore, in some embodiments, the headgear fixing device 2 includes a strap 22, which is configured to provide a force direction F to the headgear body 1 with its own tension during the detection process, thereby fastening the headgear body to the infant's head.

[0040] Specifically, the straps 22 are symmetrically arranged at the extensions 4 on both sides of the headgear body 1, and are located on the outside of the headgear. When the headgear body is fastened to the infant's head, the straps 22 tighten along the infant's jawbone and are secured at the bottom of the infant's chin. At this time, the infant can be tested while lying down. During the test, the straps 22 provide a force direction F to the headgear body 1 with their own tension, thereby securing the headgear body to the infant's head. Depending on the testing requirements, the position of the straps at the bottom of the infant's chin can be adjusted, such as near the front or back of the chin. This allows the straps to provide a variable force direction F of 0° to 90° relative to the infant's body midline M during the test, thereby securing the headgear body to the infant's head and ensuring that the required data is effectively acquired during the acquisition of EEG and / or blood oxygenation data signals.

[0041] Specifically, such as Figure 4 As shown, the headgear fixing device 2 includes a chin support 21 connected to each extension 4 and a strap 22. The straps 22 are symmetrically arranged at the extensions 4 on both sides of the headgear body 1, and the straps 22 are located on the outside of the headgear. During the testing process, if... Figure 5 As shown, the chin rest 21 is used in conjunction with the strap 22. Because the strap 22 is located on the outside of the cap, after the strap 22 is tightened, the chin rest 21 fits snugly against the infant's skin, resulting in a larger contact area between the chin rest 21 and the skin. This reduces discomfort for the infant and improves their compliance during the collection process. If the strap were located on the inside of the cap, it would fit snugly against the skin, resulting in a smaller contact area and causing a foreign body sensation and discomfort.

[0042] Specifically, the aforementioned strap 22 may be made of elastic or non-elastic material, and this application does not make a specific limitation in this regard. The headgear body 1 and the aforementioned strap 22 may be integrated into one unit.

[0043] Specifically, the aforementioned strap 22 can be arranged around the front edge of the head cap body and extend from the extension portion 4 on both sides of the head cap body (not shown in the figure). When the strap provides force in the direction F, this arrangement can make the front edge of the head cap body tighten better, so that the head cap body is more firmly fastened to the head of the infant, ensuring that the required data is effectively collected during the acquisition of EEG data and / or blood oxygen data signals.

[0044] Specifically, the aforementioned strap 22 can be arranged around the rear edge of the headgear body and extend from the extension portion 4 on both sides of the headgear body (not shown in the figure). When the strap provides force in the direction F, this arrangement can make the rear edge of the headgear body tighten better, so that the headgear body is more firmly fastened to the head of the infant, ensuring that the required data is effectively collected during the acquisition of EEG data and / or blood oxygen data signals.

[0045] Furthermore, the aforementioned straps 22 can be simultaneously arranged around the front edge and the rear edge of the headgear body, and extend from the extensions 4 on both sides of the headgear body (not shown in the figure). When the straps provide force in the direction F, this arrangement can result in better tightening of the front edge and the rear edge of the headgear body, more uniform tightening, and a more secure fastening of the headgear body to the infant's head. Alternatively, when there are two different straps around the front edge and the rear edge of the headgear body, the tightening degree of the front edge and the rear edge of the headgear body can be more flexible according to different needs, ensuring that the required data is effectively collected during the acquisition of EEG data and / or blood oxygen data signals.

[0046] Specifically, the headgear body 1 and the headgear fixing device 2 are integrated into one unit. In this application, "integrated into one unit" can mean that the headgear body 1 and the headgear fixing device 2 are spliced ​​or combined into a whole using the same or different materials, or that the headgear body 1 and the headgear fixing device 2 are themselves a whole. As for the specific integration method, this application does not make specific limitations on it.

[0047] The infant headgear provided by this utility model, by incorporating a headgear fixing device 2 (chin rest 21 and / or strap 22) with adjustable force direction F onto the headgear body 1, allows for more flexible and effective securing of the testing equipment to the infant's head during the testing process. This ensures the effective acquisition of necessary data during EEG and / or blood oxygenation signal acquisition. Furthermore, because the force direction F does not directly act on the infant's chin, it significantly reduces pressure and constriction on the infant's underdeveloped mandible and soft chin, thereby improving the infant's compliance during the data acquisition process. Moreover, the above structural design is reasonable and can effectively assist medical personnel in data acquisition.
