Description

A medical infectious disease protective device Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a head-worn medical protective device for diseases transmitted through droplets and aerosols. Background Technology

[0002] Influenza virus, a common respiratory infectious disease pathogen, primarily spreads through droplets. These droplets have relatively large nuclei, typically exceeding five micrometers in diameter, resulting in relatively short transmission distances. However, certain clinical procedures, such as throat swab sampling, endotracheal intubation, or sputum suctioning for influenza patients, can easily generate virus-carrying aerosols or trigger violent coughing, producing large quantities of infectious droplets. These droplets may splash at high speeds, and the splashing direction is not limited to the front; they can also threaten the face, eyes, and neck of healthcare workers from the sides.

[0003] Currently, standard protective measures for such scenarios typically require healthcare workers to wear medical protective masks, goggles, or full-face shields simultaneously. However, this combination reveals several inherent flaws in practical application that are incompatible with influenza protection needs: 1. As independent components, masks and goggles have conflicting protective boundaries. The nose clip of the mask has limited sealing strength, and gaps easily appear on both sides of the nose bridge during prolonged wear or user activity. These gaps are not only weak points for influenza virus droplet entry but also cause exhaled air to surge upwards, causing severe fogging of the goggles, significantly interfering with vision and forcing operational interruptions.

[0004] 2. Traditional flat-designed protective face shields mainly protect the front, providing insufficient protection against splashes from the sides, leaving the cheeks and sides of the eyes exposed.

[0005] 3. Wearing disjointed equipment for extended periods can cause continuous pressure on the ears and face due to the ear loops of the mask and the temples of the goggles. This can easily lead to skin bruising and discomfort, affecting work continuity and concentration.

[0006] Therefore, there is an urgent need for a dedicated head-worn protective device that can integrate protection, optimize for the risk of influenza droplet exposure, ensure all-round barrier and dynamic seal, and improve wearing comfort, ease of operation and flexibility of filter replacement. Summary of the Invention

[0007] The present invention aims to overcome the shortcomings of the prior art and provide a medical protective device that is comfortable to wear, reliably sealed, provides comprehensive protection, and is easy to maintain.

[0008] This invention is achieved through the following technical solution: a medical infectious disease protective device, comprising a headband including a front support, a rear support, and a soft support, wherein the soft support is detachably installed on the inner surfaces of the front and rear supports that contact the head, and the front and rear supports can be adjusted at multiple angles via a rotating mechanism; an eye protection assembly, comprising a rigid frame and a transparent cover, wherein the rigid frame includes at least two vertical supports, the vertical supports being rigidly connected to the lower side of the front support, and the transparent cover being detachably installed on the rigid frame, the transparent cover covering the main protective area of ​​the face directly in front of the eyes, and a left protective wing and a right protective wing extending backward from the left and right sides of the main protective area respectively; and a mask assembly, comprising a soft frame, a protective film, and a pull cord, wherein the upper frame of the soft frame has a U-shaped groove adapted to the contour of the bridge of the nose, the upper frame is connected to the end of the vertical supports, the protective film is fixed to the soft frame, and the pull cord completely fits the soft frame with the protective film fixed to it against the mouth and nose.

[0009] Furthermore, the front support and the rear support are made of rigid materials, and the front support and the rear support are connected to form an arc-shaped structure that conforms to the head contour.

[0010] Furthermore, the hardware frame and the front support are integrally injection molded, and the eye protection component is adjusted to fit the face via the rotation mechanism.

[0011] Furthermore, the U-shaped groove on the upper side of the soft frame is fitted with a memory foam pad that can form an airtight seal, so that the memory foam pad completely fits the bridge of the nose when worn.

[0012] Furthermore, each of the vertical supports is provided with at least two mounting holes, and a strong magnet is fixed in the mounting holes. The transparent cover is fixed to the vertical support by magnetic attraction.

[0013] Furthermore, the powerful magnet, after being installed in the mounting hole, is either protruding or recessed, forming a limiting effect with the transparent cover after being magnetically fixed.

[0014] Furthermore, the transparent cover is a curved transparent thin plate structure, and the extension range of the left protective wing and the right protective wing reaches at least to the position of the lateral projection of the cheekbone on the face.

[0015] Furthermore, the lower side of the vertical support is provided with a ball-head clip, and the upper frame of the flexible frame is provided with a fixing hole at a corresponding position, and the ball-head clip is rotatably inserted into the fixing hole.

[0016] Furthermore, the soft frame consists of a metal strip and a silicone layer, with the silicone layer wrapping around the side of the metal strip facing the face, and the protective film being bonded to the outer side of the metal strip away from the face using an adhesive.

[0017] Furthermore, the pull cord is fixed to the neck and is equipped with a length adjuster that allows for quick adjustment of tension.

[0018] The beneficial effects of this invention are as follows: 1. By integrating the goggles and mask areas into a single design, the sealing conflict and fogging problem between discrete components is solved. The U-shaped structure of the memory foam actively seals the bridge of the nose, eliminating the fogging phenomenon of goggles caused by poor mask sealing, thus ensuring clear vision and complete protection.

[0019] 2. The multi-angle adjustment of the headband enables a balanced distribution of facial pressure, dispersing the pressure to the top of the head and the back of the head, improving comfort during long-term wear and avoiding pressure-related injuries.

[0020] 3. The left and right protective wings of the transparent cover bend backward and extend to the sides of the cheekbone, making up for the blind spots of side droplet splash protection and forming an effective physical barrier on the front and sides, solving the problem of insufficient protection against side splashes by traditional face shields.

Detailed Implementation

[0023] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0024] Referring to Figures 1 to 7, this embodiment provides a medical infectious disease protective device, including a headband 1 comprising a front support 11, a rear support 12, and a soft support 13. The soft support 13 is detachably mounted on the inner surfaces of the front support 11 and the rear support 12 that contact the head. The front support 11 and the rear support 12 can be adjusted to multiple angles via a rotating mechanism 14. The eye protection component 2 comprises a rigid frame 21 and a transparent cover 22. The rigid frame 21 includes at least two vertical supports 211, which are rigidly connected to the lower side of the front support 11. The transparent cover 22 is detachable. The mask assembly 3 is mounted on the rigid frame 21. The transparent cover 22 covers the main protective area of ​​the face directly in front of the eyes, and the left protective wing 221 and right protective wing 222 are formed by bending backward from the left and right sides of the main protective area, respectively. The mask assembly 3 includes a soft frame 31, a protective film 32 and a pull cord 33. The upper frame 311 of the soft frame 31 is provided with a U-shaped groove 312 that conforms to the contour of the nose bridge. The upper frame 311 is connected to the end of the vertical support 211. The protective film 32 is fixed on the soft frame 31. The pull cord 33 completely fits the soft frame 31 with the protective film 32 to the mouth and nose.

[0025] Functional Description: The front support 11 and rear support 12 of the headband 1 form the main load-bearing frame. The soft support 13 inside the front support 11 and rear support 12 plays a role in distributing pressure, effectively reducing the hard pressure on the user's forehead and occipital bone, and improving wearing comfort. The rotating mechanism 14 connecting the front support 11 and the rear support 12 allows adjustment of the angle between them, enabling the entire device to adapt to different users' head circumference and facial tilt angles, which is the basis for achieving personalized fitting.

[0026] The goggle assembly 2 provides a physical barrier for the eyes and face. The rigid frame 21 is a rigid skeleton that securely connects the vertical support 211 to the headband 1. The vertical support 211 is bolted together, ensuring the integrity and stability of the structure. The transparent cover 22 protects the eyes from droplet splashes. The main protective area on the front provides forward visibility and protection. The left and right protective wings 221 extend backward, extending the protection range to the sides of the cheeks, effectively blocking lateral droplet splashes and solving the problem of insufficient side protection in traditional face shields.

[0027] The mask component 3 provides respiratory protection for the mouth and nose. The soft frame 31 is made of a highly malleable metal sheet material, which can effectively adapt to different face shapes. The U-shaped groove 312 on the upper frame 311 is thickened to fit the shape of the bridge of the nose, and the rigidity is locally enhanced to provide reinforced support for the bridge of the nose. The protective membrane 32 serves as a replaceable filter medium, realizing the respiratory protection function. The pull cord 33 provides a pulling force around the head and neck, pulling the entire soft frame 31 and protective membrane 32 inward to actively conform to the contours of the user's mouth, nose and face.

[0028] Referring to Figures 1 and 2, this embodiment provides a medical infectious disease protective device. The front support 11 and the rear support 12 are made of rigid materials, and when connected, they form an arc-shaped structure that conforms to the contour of the head. The front support 11 and the rear support 12 are made of rigid PP material and form an arc-shaped structure that fits the head, ensuring that the headband 1 has sufficient structural strength and shape retention. The stable arc-shaped frame can reliably support the weight of the connected eye protection component 2 and mask component 3.

[0029] Referring to Figures 3 and 4, this embodiment provides a medical infectious disease protective device. A memory foam pad 313, capable of creating an airtight seal, is installed in the U-shaped groove 312 on the upper side of the soft frame 31. When worn, the memory foam pad 313 completely conforms to the bridge of the nose. The addition of the memory foam pad 313 within the U-shaped groove 312 solves the problem of difficulty in sealing the nose bridge area due to bone protrusion. The memory foam pad 313 can slowly deform under pressure, adapting to the specific shape of different users' nose bridges, filling the tiny gaps between the skin and the rigid frame, thereby achieving an airtight seal at the bridge of the nose and preventing fogging of the goggles due to leakage from the top of the mask during exhalation.

[0030] Referring to Figures 5 to 7, this embodiment provides a medical infectious disease protection device. Each vertical support 211 has at least two mounting holes 212. A strong magnet 213 is fixed in the mounting hole 212. The transparent cover 22 is fixed to the vertical support 211 by magnetic attraction. After installation in the mounting hole 212, the strong magnet 213 is either protruding or recessed, forming a limiting effect with the transparent cover 22 after magnetic fixation. By providing mounting holes 212 with strong magnets 213 on the vertical support 211, magnetic installation of the transparent cover 22 is achieved, allowing the transparent cover 22 to be quickly and easily installed and removed without clips or screws. When attracted to the corresponding structure on the transparent cover 22, the installation state of the strong magnet 213 is protruding or recessed, generating a horizontal limiting effect in addition to the vertical attraction force, which can prevent the transparent cover 22 from sliding laterally when touched from the side or when the user turns their head quickly, ensuring the accuracy of the installation position.

[0031] Referring to Figure 7, this embodiment provides a medical infectious disease protective device. The transparent cover 22 is a curved transparent thin plate structure, and the extension range of the left protective wing 221 and the right protective wing 222 reaches at least to the position of the lateral projection of the cheekbone. The transparent cover 22 is a curved thin plate, which provides a wider field of view that is more in line with the visual habits of the human eye and reduces optical distortion. The quantitative requirement that the protective wings extend to the side of the cheekbone ensures that the protection against lateral droplet splashes has a clear and sufficient physical coverage range, providing all-around protection for the face.

[0032] Referring to Figures 5 and 6, this embodiment provides a medical infectious disease protection device. A ball-head clip 214 is provided on the lower side of the vertical support 211, and a fixing hole 316 is provided on the upper frame 311 of the soft frame 31 at a corresponding position. The ball-head clip 214 is rotatably inserted into the fixing hole 316. Through the cooperation of the ball-head clip 214 and the fixing hole 316, the mask assembly 3 and the goggle assembly 2 are connected. This forms a hinged connection, allowing the soft frame 31 to rotate and swing slightly relative to the vertical support 211 under the tension of the pull cord 33. This allows the mask assembly 3 to adapt to the complex dynamic changes in the mouth and nose caused by the user speaking or slightly moving their chin, maintaining a tight fit at all times.

[0033] Referring to Figure 4, this embodiment provides a medical infectious disease protective device. The soft frame 31 consists of a metal strip 314 and a silicone layer 315. The silicone layer 315 wraps around the side of the metal strip 314 facing the face. The protective film 32 is fixed to the outer side of the metal strip 314 away from the face by adhesive bonding. The metal strip 314 provides the necessary skeletal support, allowing the entire frame to maintain its shape under the tension of the pull cord and providing uniform tension to the protective film 32. The silicone layer 315 facing the face provides a soft, skin-friendly contact surface, improving wearing comfort and avoiding direct pressure on the face from hard materials. The protective film 32 has a filter and is fixed to the outside of the metal strip 314 by adhesive bonding, effectively preventing viruses from entering while ensuring air circulation.

[0034] Referring to Figures 1 and 2, this embodiment provides a medical infectious disease protective device. The pull cord 33 is fixed to the neck and is equipped with a length adjuster 331 for quick adjustment. The length adjuster 331 allows the user to quickly and precisely adjust the tightness of the pull cord according to their own feelings and face shape, thereby controlling the fit pressure of the mask assembly 3 on the face and finding the most comfortable tightness for themselves while ensuring a seal.

[0035] Example 2: This example is based on Example 1. Referring to Figure 5, the difference between this example and Example 1 is that in this example, the rigid frame 21 and the front support 11 are integrally injection molded. The eye protection component 2 is adjusted to fit the face via a rotating mechanism 14. The rigid frame 21 and the front support 11 are manufactured through integral injection molding, achieving a rigid connection between them without connecting parts. This eliminates shaking caused by loose screws, enhancing the stability and reliability of the eye protection component 2. The eye protection component 2 can be adjusted via the rotating mechanism 14, allowing for fine adjustment of the tilt angle of the transparent cover 22 according to the user's face shape and viewing habits. This optimizes the field of vision and positions the U-shaped groove 312 of the mask component 3 for a better seal on the bridge of the nose.

[0036] The implementation principle of this invention lies in integrating an eye protection component 2 and a mask component 3 for mouth and nose protection using an adjustable headband 1 as a support platform. A series of targeted designs address issues of sealing, comfort, and convenience. In use, the user first adjusts the angle of the headband 1 using the rotation mechanism 14 to fit their head shape and line of sight. Then, the soft frame 31 with the protective film 32 is placed over the nose and mouth, and the neck strap 33 is tightened and secured using the length adjuster 331, ensuring the mask component 3 fits snugly against the face under the tension of the strap. The memory foam pad 313 within the U-shaped groove 312 adaptively seals the bridge of the nose. Finally, the transparent cover 22 with side protective wings is magnetically attached. Throughout the wearing process, the ball-head clip 214 allows for dynamic micro-adjustment of the mask component 3 with facial contours, and the silicone layer 315 provides a comfortable contact surface. When it is necessary to change the mask or clean the cover, it can be easily disassembled, achieving a balance between protective effect, wearing experience, and ease of use and maintenance.

[0037] The specific embodiments described above do not constitute a limitation on the scope of protection of this application. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the scope of protection of this application.
