Description

Technical Field

[0001] This utility model relates to the field of intracranial imaging technology, and in particular to a head-mounted intracranial vascular imaging acquisition and analysis instrument. Background Technology

[0002] With social and economic development, modern people face increasing life pressures and a faster pace of life, neglecting their health and quality of life. Unhealthy habits and lifestyles lead to various diseases that endanger human life and health. The World Health Organization's 2019 Global Health Estimates report states that stroke is the second leading cause of death worldwide, after heart disease. Stroke, commonly known as apoplexy, is an ischemic brain disease caused by vascular occlusion or ruptured thrombi, damaging brain tissue. Intracranial atherosclerotic stenosis (ICAS) is a major cause of ischemic stroke, its pathogenesis involving atherosclerotic plaque embolism, and it most commonly occurs in the middle cerebral artery and basilar artery. In recent years, secondary prevention of ischemic stroke has received unprecedented attention in my country. Combining advanced technologies from various disciplines to scientifically prevent ischemic stroke caused by ICAS, assisting in early diagnosis and effective treatment, is of positive significance for safeguarding the health of the Chinese people.

[0003] Currently, existing head-mounted intracranial vascular imaging and analysis devices typically use a fixed headband design. While this meets basic wearing requirements, it cannot adapt to the different curvatures of a patient's skull and lacks a flexible tightness adjustment mechanism. As a result, the device can easily cause pressure on the patient's skin during prolonged use, leading to discomfort and even affecting the accuracy of data acquisition. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the inability to adaptively fit the curvature of the skull of different patients and the lack of flexible tightness adjustment, which leads to discomfort during use and reduces the accuracy of data acquisition. Therefore, this invention proposes a head-mounted intracranial vascular image acquisition and analysis instrument.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A head-mounted intracranial vascular imaging acquisition and analysis device includes:

[0007] An elastic headgear and a near-infrared spectral sensor are included. The inner wall of the elastic headgear is fixedly provided with a sponge pad, and the top of the elastic headgear is sewn with multiple evenly distributed plastic strips in a ring shape.

[0008] The elastic headgear is equipped with an installation component for mounting a near-infrared spectral sensor, and a wearing component that is convenient for patients with different head sizes to wear.

[0009] In one possible design, the mounting assembly includes multiple mounting brackets fixedly mounted on top of multiple plastic strips, with spring plates fixedly mounted on both sides of the inner wall of each mounting bracket. The near-infrared spectral sensor can be detached and placed inside the mounting bracket, with the spring plates on both sides of the inner wall of the mounting bracket abutting against both sides of the near-infrared spectral sensor.

[0010] In one possible design, the wearing component includes a main strap and a secondary strap that are fixedly disposed on both sides of the bottom of the elastic headgear. One end of the main strap is fixedly provided with a threading loop, and the secondary strap can be detached and threaded through the threading loop. The outer sides of the secondary strap are respectively sewn with a Velcro loop side and a Velcro hook side.

[0011] In one possible design, silicone pads are fixedly provided on the inner sides of both the main strap and the secondary strap, and the silicone pad located on the inner side of the main strap can cover the top of the threading loop.

[0012] In one possible design, the top of the elastic headgear is sewn with multiple main and secondary fabric strips between plastic strips. The bottom of the main fabric strips is sewn with a male buckle, and the top of the secondary fabric strips is sewn with a female buckle. The male buckle and the female buckle are compatible and can be detached and fastened.

[0013] In one possible design, one end of each of the plurality of near-infrared spectral sensors is electrically connected to a wiring harness, and the plurality of near-infrared spectral sensors are electrically connected to the analyzer through the wiring harness.

[0014] In this application, upon initial use, the patient's scalp is first cleaned as needed, and hair accessories, grease, and other interfering substances that may affect the signal are removed. Then, the elastic headgear is placed over the patient's head. During the application of the elastic headgear, the position of the plastic strips is adjusted to ensure they conform evenly to the curved surface of the skull. The secondary strap is then passed through the loop of the main strap and pulled to adjust the tightness according to the patient's comfort (ensuring that the silicone pad completely covers the top of the loop during this process). Once the tightness is appropriate, the Velcro side of the secondary strap is glued to the hook side, thereby further securing the elastic headgear to the patient's head through the secondary strap and the main strap, making its position more stable.

[0015] Subsequently, based on the data acquisition requirements, select an appropriate number of near-infrared spectral sensors and insert them one by one into the corresponding mounting brackets. During insertion, press the spring plates on both sides of the near-infrared spectral sensors to their maximum stroke and then release them, using the spring plate's rebound force to fix the sensors. Then, gather all the sensor wires along the top edge of the elastic headgear and place all the wires between the main and secondary fabric strips in the corresponding positions. Fasten the wires using the male and female buckles on the main and secondary fabric strips to bind them and prevent tangling. Then, insert the combined end of the wires into the analyzer host interface, ensuring the interface is securely connected without any looseness. Finally, turn on the analyzer power, and the system will automatically identify the number of sensors and perform calibration (approximately 30 seconds). After calibration, check the signal strength of each sensor (usually displayed by LED indicators or screen waveforms) to ensure signal stability. Based on clinical needs, set the acquisition duration (5-10 minutes recommended), sampling frequency, and other parameters on the analyzer interface.

[0016] Click the "Start" button to begin collecting intracranial vascular imaging data. During the collection process, the patient must keep their head still and avoid actions that may produce motion artifacts, such as talking or blinking. Observe the real-time data waveform on the analyzer screen. If abnormal fluctuations occur (such as signal interruption or excessive noise), the collection should be paused and the device status checked.

[0017] This utility model has the following beneficial effects:

[0018] This invention enables rapid installation and disassembly of near-infrared spectral sensors through the design of the installation components. The elastic rebound force of the spring sheet can be adapted to sensors of different sizes and ensures installation stability. At the same time, it is easy to flexibly adjust the number of sensors according to clinical needs, effectively improving the ease of operation and flexibility of use of the equipment.

[0019] This invention combines an elastic headband, plastic strips, and wearing components to achieve an adaptive fit to the skull curvature of different patients, while also allowing for tightness adjustment. This effectively avoids pressure on the patient's skin, significantly improving the comfort and adaptability of the device and ensuring safety and stability during long-term use.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Reference Figure 1-4 An analyzer comprising:

[0028] The device consists of an elastic headgear 1, a near-infrared spectral sensor 4 (model: NIRONE Sensor S), mounting components, and wearing components. The elastic headgear 1 serves as the basic load-bearing structure of the entire device. Its inner wall is fixed with a sponge pad, which can provide a soft and comfortable contact surface for the patient's head. The top of the elastic headgear 1 has multiple evenly distributed plastic strips 2 sewn in a ring. These plastic strips 2 have a certain degree of elasticity and can be bent appropriately, which can fit well with the curvature of different patients' heads. Together with the elastic headgear 1, they further enhance the fit with the head.

[0029] The mounting assembly is mainly used for the installation of the near-infrared spectral sensor 4. Specifically, the mounting assembly includes multiple mounting brackets 3, which are fixedly mounted on the top of multiple plastic strips 2. The mounting brackets 3 are connected to the plastic strips 2. Spring plates 301 are fixedly installed on both sides of the inner wall of each mounting bracket 3. The near-infrared spectral sensor 4 can be detached and placed in the mounting bracket 3. During installation, after pressing the spring plates 301 on both sides of the near-infrared spectral sensor 4 to the maximum stroke, the spring plates 301 are automatically released. The sensor can be fixed in the mounting bracket 3 by the rebound force of the spring plates 301. This design not only facilitates the installation and removal of the near-infrared spectral sensor 4, but also allows for flexible changes in the number of near-infrared spectral sensors 4 according to different needs, meeting diverse clinical data collection requirements.

[0030] The wearing component is designed for patients with different head sizes. It includes a main strap 5 and a secondary strap 7, which are fixedly installed on both sides of the bottom of the elastic headgear 1. One end of the main strap 5 is fixed with a loop 6, and the secondary strap 7 can be detached and threaded through the loop 6. The outer sides of the secondary strap 7 are sewn with Velcro loop 8 and Velcro hook 9, respectively. In actual wearing, the elastic headgear 1 is placed over the patient's head. During the covering process, the position of the plastic strip 2 is adjusted so that it fits evenly against the curved surface of the skull. Then, the secondary strap 7 is threaded through the loop 6 of the main strap 5 and pulled. The tightness is adjusted according to the patient's comfort. When the tightness is appropriate, the Velcro loop 8 and Velcro hook 9 on one side of the secondary strap 7 are glued together. Thus, the secondary strap 7 and the main strap 5 further fix the elastic headgear 1 to the patient's head, making its position more stable.

[0031] In addition, silicone pads 10 are fixedly installed on the inner side of both the main strap 5 and the secondary strap 7. The silicone pads 10 located on the inner side of the main strap 5 can cover the top of the insertion ring 6. This design allows the silicone pads 10 to cover the insertion ring 6 when the patient wears the garment, preventing the insertion ring 6 from contacting the patient's skin and causing pressure, thus improving the comfort of wearing the garment.

[0032] This application can be used in the field of head-mounted intracranial vascular imaging acquisition and analysis technology, and can also be used in other fields applicable to this application.

[0033] Example 2

[0034] An improvement based on Embodiment 1: A head-mounted intracranial vascular image acquisition and analysis instrument, which is applied to the field of head-mounted intracranial vascular image acquisition and analysis technology. In order to prevent the wire bundles 401 of multiple near-infrared spectral sensors 4 from tangling, multiple main fabric strips 11 and secondary fabric strips 12 are sewn between the plastic strips 2 at the top of the elastic headgear 1. The bottom of the main fabric strip 11 is sewn with a male buckle 13, and the top of the secondary fabric strip 12 is sewn with a female buckle 14. The male buckle 13 and the female buckle 14 are compatible and can be detached and fastened.

[0035] One end of each of the multiple near-infrared spectral sensors 4 is electrically connected to a wire harness 401. The multiple near-infrared spectral sensors 4 are electrically connected to the analyzer through the wire harness 401. After the near-infrared spectral sensors 4 are installed, the wire harnesses 401 of all sensors are gathered along the top edge of the elastic head cover 1, and all the wire harnesses 401 are placed between the main fabric strip 11 and the secondary fabric strip 12 at the corresponding positions. Then, the wire harnesses 401 are fastened by the male buckle 13 and the female buckle 14 on the main fabric strip 11 and the secondary fabric strip 12, thereby binding the wire harnesses 401 to ensure that the wire harnesses 401 are neat and orderly and to avoid tangling.

[0036] However, as is well known to those skilled in the art, the working principle and wiring method of the infrared spectral sensor 4 are commonplace and are all conventional methods or common knowledge, so they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0037] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
