Description

Technical Field

[0001] The utility model relates to a medical auxiliary treatment device, in particular to a hard elastic cap used for near-infrared brain function imaging and electroencephalogram. Background Art

[0002] Near-infrared brain functional imaging and EEG are non-invasive methods for studying brain activity and cognitive function. By measuring the near-infrared spectrum of the scalp surface, changes in blood oxygen concentration, and EEG signals, information about brain activity can be obtained.

[0003] Existing near-infrared brain functional imaging and EEG technologies usually require the use of multiple sensors to fix and detect the position of the head and ensure that the sensors are in close contact with the head to improve signal quality. However, traditional sensor fixation solutions have some disadvantages, such as complex operation, discomfort, easy sliding or loosening, which affect the accuracy and reliability of data collection.

[0004] In the field of near-infrared brain functional imaging and EEG, the fit of the hat has always been a problem. When conducting near-infrared or electrical stimulation experiments, it is necessary to ensure that the hat fits tightly to the head to minimize external light source interference or signal loss. However, due to differences in people of different ages and head circumferences, traditional cloth hats or pure hard hats cannot meet the fit needs of everyone.

[0005] Cloth caps are difficult to adapt to various head circumferences due to their wide variety of sizes. Although pure hard caps are stable, they cannot completely fit the curve of the head, resulting in an unsatisfactory fit. This poor fit may cause the sensor to loosen, shift, or feel uncomfortable, affecting the accuracy and reliability of data collection. Utility Model Content

[0006] In view of the problems existing in the prior art, the purpose of the utility model is to provide a hard elastic cap for near-infrared brain function imaging and electroencephalography to solve the problem of fitting for different age groups and different head circumferences.

[0007] To achieve the above purpose, the present invention is specifically implemented through the following technologies:

[0008] A hard elastic cap for near-infrared brain function imaging and electroencephalogram, comprising a cap body, wherein the cap body is a hard skeleton structure that fits the human head, wherein a plurality of elastic fixing seats are arranged inside the hard skeleton structure, and wherein the elastic fixing seats are provided with probe mounting holes that penetrate the inside and outside of the cap body.

[0009] The rigid frame provides stability and structural support to ensure that the hat fits snugly on the head. It maintains the shape and stability of the hat and prevents the sensor from shifting or loosening due to movement or external interference.

[0010] The elastic mount can be adjusted and retracted according to the individual head circumference. By adjusting the position and tension of the elastic mount, the hat can be ensured to achieve the best fit for people with different head circumferences, thereby improving the accuracy and reliability of data collection.

[0011] The elastic fixing seat is provided with probe mounting holes that penetrate the inside and outside of the cap body. These mounting holes can be used to flexibly install near-infrared fiber optic probes or EEG electrode probes. Their position and number can be adjusted according to specific needs to achieve optimal probe layout and signal acquisition.

[0012] Through the above technical solutions, the hard elastic cap can effectively solve the fit problem in near-infrared brain functional imaging and EEG experiments. It provides better fit, stability and adjustability, and adapts to people with different head circumferences and head curves. At the same time, the design of the probe mounting hole makes the cap flexibly adaptable to different detection needs, and can ensure that the sensor is accurately fixed in the correct position, thereby improving the accuracy and reliability of data collection. This hard elastic cap can provide users with a better user experience and enhance the reliability and repeatability of the test results.

[0013] Furthermore, the hard skeleton structure is connected to each other through a plurality of ribs to form a hemispherical network distribution.

[0014] Through the staggered connection of the ribs, the rigid skeleton structure can provide uniform support, so that the hat is evenly distributed around the head. This can avoid local pressure or discomfort, ensure that the entire head surface is in close contact with the hat, and improve comfort and stability. The hemispherical mesh distribution of the rib connection method can improve the strength and stability of the entire rigid skeleton structure. It can effectively resist external pressure and twisting force, and avoid deformation or loosening of the hat due to head movement.

[0015] The characteristics of the hemispherical mesh distribution, the hard skeleton structure can better fit the curve of the head. It can adjust the geometry of the hat as the shape of the head changes, ensuring a better fit, reducing gaps, and improving the accuracy of imaging or signal acquisition. Secondly, the mesh hollowing can make the position of the probe intuitively visible. This helps to ensure that the probe is correctly installed in the predetermined position to achieve the best data acquisition effect. Users can choose different hollow holes to install the probe according to specific needs, and achieve flexible probe layout. It is very beneficial for the adaptability of individual differences, specific experimental designs or research needs. The mesh hollowing makes the hat more breathable and is conducive to the heat dissipation around the probe. It is very important for experiments that are used for a long time or need to keep the head comfortable and the temperature stable. The mesh distribution can provide better visualization of the probe position, flexible layout, breathability and heat dissipation, and reduce interference.

[0016] Furthermore, the elastic fixing seat is arranged at a node of the mesh structure.

[0017] The mesh structure is connected by ribs that are interlaced to form a hemispherical mesh distribution, and the nodes can provide greater strength. Setting the elastic fixing seat at the node can effectively enhance the fixing strength of the probe and prevent the probe from loosening or shifting due to head movement. The probe is detected through the probe hole on the elastic fixing seat, so that the probe can be adaptively adjusted to enter according to the shape of the head. This can ensure the stability of the probe and avoid deformation of the hat or loosening of the probe due to head movement. The elastic fixing seat can improve the fixing strength and stability of the probe by designing it at the node of the mesh structure, ensure wearing comfort and avoid data acquisition errors. It is one of the key components in near-infrared brain functional imaging and EEG experiments, which can help the tester install the probe quickly and accurately, and improve the quality and reliability of the test.

[0018] Since the elastic fixing seat is made of soft material and has a certain degree of elasticity, it can reduce pressure on the head while maintaining the fixing force, thereby improving the user's comfort and wearing experience.

[0019] Furthermore, the nodes of the mesh structure are provided with threaded holes for connecting with the external threads of the elastic fixing seat.

[0020] By adjusting the rotation angle or lifting height of the elastic fixing seat, the fixing force between the probe and the hat can be controlled. If the fixing force is not strong enough, the probe may become loose or shifted, affecting the accuracy and reliability of data collection; if the fixing force is too strong, it may cause pressure or even damage to the head. Therefore, by twisting the rotation angle or lifting height of the elastic fixing seat, the fixing force can be controlled according to actual needs to improve the wearing comfort and data collection effect.

[0021] The threaded hole can be easily connected with the external thread of the elastic fixing seat, so as to achieve fast and accurate installation and removal. No additional tools are required during the installation process, just insert the elastic fixing seat into the threaded hole and rotate it. This can greatly improve the efficiency and speed of operation and save time.

[0022] Furthermore, the probe mounting holes are arranged at corresponding detection points, and the number thereof is 10 to 20.

[0023] The probe mounting hole is set at the corresponding detection point, which has the functions and characteristics of accurate positioning, stable fixation, easy operation and adaptability to different detection points. It plays an important role in the fields of brain function imaging, physiological signal detection, etc., ensuring the close combination of instruments and equipment with the measured parts, and ensuring the accuracy and reliability of data collection.

[0024] Furthermore, a buffer pad is provided on the end surface of the elastic fixing seat extending into the cap body.

[0025] The cushion of the elastic fixing seat can absorb external shock or vibration and play a buffering role. When the head moves or collides, the cushion can reduce the impact on the probe and the measured part, reducing the potential risk of injury. The cushion can provide a certain degree of softness and comfort, reducing the discomfort of the wearer during use. It can prevent the elastic fixing seat from causing excessive pressure on the head and improve the comfort and acceptability of wearing. The cushion of the elastic fixing seat can protect the measured part from the direct influence of external forces. It can play a certain isolation role, reduce the interference of external pressure on the measured part, and ensure the accuracy and stability of data collection. Through the above characteristics, the end face of the elastic fixing seat extending into the cap body is provided with a cushion, which has the functions and characteristics of buffering, reducing discomfort, protecting the measured part and increasing stability. This design can improve the comfort and safety of the wearer, while protecting the measured part and ensuring the accuracy and reliability of data collection.

[0026] Furthermore, a card slot is provided in the probe mounting hole for card connection with the near-infrared optical fiber probe / EEG electrode probe.

[0027] The card slot in the probe mounting hole can clamp the near-infrared fiber optic probe or the EEG electrode probe in the probe mounting hole to prevent it from moving or shaking during use. The card slot makes the insertion and removal of the probe more convenient. The operator can easily insert the near-infrared fiber optic probe or the EEG electrode probe into the card slot and fix it in the probe mounting hole. This simplifies the operation process and improves efficiency. The card slot in the probe mounting hole can be suitable for different types of near-infrared fiber optic probes or EEG electrode probes, and has strong versatility. By selecting the appropriate card slot, different models of probes can be matched to meet different detection needs. A card slot is provided in the probe mounting hole for clamping with the near-infrared fiber optic probe or the EEG electrode probe, which has the functions and characteristics of traction fixation, simple and easy to use, strong versatility and high reliability.

[0028] Furthermore, the elastic mounting seat is detachably connected to the rib.

[0029] The detachable connection design between the elastic mount and the rib makes it easier to maintain and replace the device. When the elastic mount or rib needs to be repaired or replaced, they can be easily removed without affecting the entire device. The detachable connection design gives the device greater flexibility. According to specific needs and application scenarios, the appropriate elastic mount and rib combination can be selected and freely assembled and disassembled. This allows devices with different configurations to meet different usage requirements.

[0030] Furthermore, the elastic fixing seat is an elastic rubber ring or a spiral spring structure.

[0031] The elastic fixing seat adopts an elastic rubber ring or a spiral spring structure, which can provide excellent shock absorption when the device is working. The elastic rubber ring can buffer shock and vibration, making the device run more smoothly and less prone to interference and damage. It can adapt to different environments. The number of elastic fixing seats can be selected according to actual needs. This design allows the device to adapt to different environments and application scenarios, taking into account the functions of anti-shake and support. The elastic fixing seat adopts an elastic rubber ring or a spiral spring structure, which has high reliability and service life. Even in the case of long-term and high-frequency use, it is not easy to get fatigue and damage, thus ensuring the stability and reliability of the device.

[0040] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0041] Figure 1 It is a hard elastic cap used for near-infrared brain functional imaging and EEG

[0042] like Figure 1 As shown, this embodiment provides a hard elastic cap for near-infrared brain functional imaging and EEG, including a cap body, the cap body is a hard skeleton structure 1 that fits the human head, 21 elastic fixing seats 2 are arranged in the hard skeleton structure 1, and the elastic fixing seats 2 are provided with probe mounting holes 3 that pass through the inside and outside of the cap body.

[0043] The rigid skeleton structure 1 can be made of a variety of materials, for example: Plastics: such as polypropylene (PP), polyethylene (PE), polyurethane (PU) and other plastic materials with strong plasticity and durability. Metal alloys: such as aluminum alloys, titanium alloys and other metal materials with high strength and good stability. Carbon fiber composite materials: light weight, high strength and excellent mechanical properties. Silicone: a non-toxic material with softness and elasticity, commonly used in medical devices. These materials have different characteristics and applicability, and suitable materials can be selected according to specific needs to construct a rigid skeleton structure. This embodiment uses polypropylene (PP). This material is lightweight, high strength, good mechanical properties, and has a low cost.

[0044] There are many ways to form a skeleton structure. Common methods include: Injection molding: By injecting the molten material into the mold, a hard skeleton structure is formed in the mold. Processing molding: By cutting, drilling, milling and other processing processes on the raw materials, a specific skeleton structure is formed. Hot pressing molding: After the raw materials are heated to a certain temperature, the required skeleton structure is formed under the action of pressure. 3D printing molding: By stacking the three-dimensional model data designed by CAD layer by layer, a specific skeleton structure is formed. This method is suitable for manufacturing skeleton structures with complex shapes and highly personalized requirements. Fiber winding molding: By winding slender materials such as glass fiber and carbon fiber around the mold, a specific skeleton structure is formed. The use of a hard skeleton structure can provide sufficient support and stability to ensure that the detection cap can maintain integrity and reliability under various circumstances.

[0045] In this embodiment, the rigid skeleton structure 1 is staggered and connected to form a hemispherical mesh distribution through 32 ribs 11. These ribs are staggered and connected to form a hemispherical mesh distribution, which can better disperse external pressure and impact force, and improve the durability and impact resistance of the detection cap. The hemispherical mesh distribution method can make the detection cap fit the head better, reduce internal stress and deformation, and improve the comfort and safety of the detection cap.

[0046] Furthermore, the elastic fixing seat 2 is arranged at the node of the mesh structure. The elastic fixing seat 2 can be fixed in one piece or detachably fixed to the node of the mesh structure. The elastic fixing seat can be an elastic ring structure that can be deformed freely to adapt to the shape and size of the head, and can also provide sufficient support force to maintain the position and shape of the detection cap. By arranging an elastic fixing seat at each node of the mesh structure, the comfort, fit and stability of the medical detection cap can be improved.

[0047] Furthermore, the nodes of the mesh structure are provided with threaded holes for connecting with the external threads of the elastic fixing seat 2 .

[0048] Threaded holes are machined on the nodes of the mesh structure, which can match the external threads of the elastic fixing seat. By rotating the elastic fixing seat 2, you can connect it tightly to the node, thereby ensuring the stability and reliability of the detection cap.

[0049] This threaded connection design facilitates the assembly and maintenance of the test cap. The elastic holder and the mesh structure can be processed and tested separately, and then combined together by threaded connection during final assembly. If the elastic holder needs to be repaired or replaced, it can be disassembled and reinstalled by simply rotating it, which greatly simplifies the manufacturing and maintenance process. By providing threaded holes on the mesh structure nodes and threaded connections of the elastic holder, the stability and maintainability of the medical test cap are improved.

[0050] Furthermore, the probe mounting holes 3 are arranged at corresponding detection points, and the number is 10 to 20. The number and position of the probe mounting holes will be determined according to the specific detection requirements and application scenarios. If multiple detection points need to be detected, the number of probe mounting holes will increase. Similarly, if different detection points need to be detected, the position of the probe mounting holes will be adjusted accordingly. These probe mounting holes can be used to install and fix the detection probe. By installing the probe in the probe mounting hole, it can be ensured that the probe is in the correct position for accurate detection. The design of the probe mounting hole also needs to take some factors into consideration. For example, the size and shape of the hole need to match the probe to ensure that the probe can be installed and removed smoothly. At the same time, the position of the probe mounting hole also needs to be precisely controlled to ensure that the probe can be aligned with the corresponding detection point for detection. This hard skeleton structure can easily install and fix the detection probe by setting the probe mounting hole at the corresponding detection point, thereby realizing accurate detection of the detection point.

[0051] Further, such as Figure 2 As shown, the end surface of the elastic fixing seat 2 extending into the cap body is provided with a buffer pad 4. The buffer pad is a soft, elastic material that can provide additional buffering and support, so that the detection cap fits the head better and reduces internal stress and deformation. At the same time, the buffer pad can also reduce the pressure of external impact force on the head and improve the safety of use.

[0052] Furthermore, a card slot 5 is provided in the probe mounting hole 3 for connecting with the near-infrared fiber optic probe / EEG electrode probe. The shape and size of the card slot 5 need to match the near-infrared fiber optic probe / EEG electrode probe to ensure that the probe can be smoothly installed and disassembled. At the same time, the position of the card slot 5 also needs to be precisely controlled to ensure that the probe can be aligned with the corresponding acupuncture points for detection. The card slot 5 enables the probe to be more firmly installed in the probe mounting hole, thereby ensuring the stability of the position of the probe during the detection process to obtain more accurate detection results. When using the elastic cap, put it on first, adjust it to fit the human head, and then install the near-infrared fiber optic probe / EEG electrode probe, so that detection can be performed simultaneously when the holes are misaligned.

[0053] Furthermore, the elastic mounting seat 2 is detachably connected to the rib 11. The detachable connection allows the elastic mounting seat and the rib to be manufactured and tested separately, and then combined together through a detachable connection method during the final assembly. This method can improve the efficiency of manufacturing and maintenance, and at the same time, the elastic mounting seat or the rib can be easily replaced to meet different application requirements. The detachable connection method includes screws, latches, buckles, etc., and the appropriate connection method is selected according to the specific application scenario and manufacturing process. At the same time, in order to ensure that the connection between the elastic mounting seat and the rib is firm, the connection part needs to be carefully designed and manufactured to provide sufficient connection strength and stability. By adopting a detachable connection method for the elastic mounting seat and the rib, the manufacturing and maintenance efficiency of the medical detection cap can be improved, and at the same time, the components can be easily replaced to meet different application requirements, and it is convenient to clean, replace and maintain.

[0054] In this embodiment, the elastic fixing seat 2 is an elastic rubber ring. The elastic rubber ring can provide good elastic fixing performance, can adapt to the shape and size of the head, and provide sufficient support force to maintain the position and shape of the detection cap. This material also has excellent wear resistance and impact resistance, which can extend the service life and safety of the detection cap. By designing the elastic fixing seat as an elastic rubber ring, the comfort, stability and durability of the medical detection cap can be improved.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
