Description

Technical Field

[0001] The invention relates to the technical field of stomatology clinic and teaching, in particular to a splash-proof disposable eye mask for stomatology treatment. Background Art

[0002] Periodontal disease and endodontic disease are the two most common oral diseases. During treatment, ultrasonic scaling and scaling, filling with a high-speed turbine, and irrigation and medication application are routine procedures in clinical diagnosis and treatment. These procedures generate droplets and sprays that may splash into the eyes of patients or medical staff. Therefore, protecting the eyes of patients and medical staff from droplets, blood, and other liquids, isolating and avoiding aerosol environments generated by high-speed handpieces or ultrasonic scalers, and reducing occupational exposure to infections (such as conjunctivitis and hepatitis B) are all crucial issues that cannot be ignored for both doctors and patients. For this reason, the Department of Periodontology and the Department of Endodontics at Peking University Hospital of Stomatology have previously implemented reusable goggles for patient treatment. Because these goggles are non-disposable, nurses disinfect them with disinfectant wipes for each patient after treatment and then pass them on to the next patient. Many patients are reluctant to wear the reusable goggles provided by the hospital, increasing safety risks during diagnosis and treatment. In addition, existing goggles are made of hard plastic, which patients feel are ill-fitting and uncomfortable, and they tend to refuse this protective measure, which affects the prevention of clinical occupational exposure risks. How to solve this problem has become a focus issue that needs to be urgently addressed in clinical practice. Summary of the Invention

Detailed Description of the Invention

[0018] The following is in conjunction with the drawings ( Figure 1) and embodiments are used to illustrate the present invention.

[0019] Figure 1 is a schematic structural diagram of a disposable eye mask for preventing splashing during dental treatment to implement the present invention. Refer to Figure 1 As shown, a disposable eye mask for preventing splashing during dental treatment includes a long strip-shaped viewing window hole in the eye socket area opened in the middle part of the non-woven fabric face mask 1 with a left ear loop cord 2 and a right ear loop cord 3. An eye socket area covering eye transparent film 12 is covered on the long strip-shaped viewing window hole in the eye socket area. A mask lower edge built-in shaping metal strip 10 is provided at the lower edge of the non-woven fabric face mask 1.

[0020] The eye socket area covering eye transparent film 12 adopts a PET / CPP composite film. The eye socket area covering eye transparent film 12 adopts a PLA / PBAT biodegradable composite film. Hydrophobic coatings of fluorinated silica nanoparticles in the eye socket area are provided on both the inner surface and the outer surface of the eye socket area covering eye transparent film 12. Nano-scale microporous arrays 13 for ensuring the breathability of the eye mask are provided around the periphery of the eye socket area covering eye transparent film 12 on the non-woven fabric face mask 1.

[0021] The upper edge of the non-woven fabric face mask 1 is an upwardly convex eyebrow bone surface fitting arc 5, the left edge is a left side face fitting line 6, the right edge is a right side face fitting line 7, the lower edge is integrally arched, and the lower edge is successively a left cheekbone surface fitting line 8, a nose bridge convex surface fitting arc 4, and a right cheekbone surface fitting line 9 from left to right.

[0022] The length of the long strip-shaped viewing window hole in the eye socket area is 16 cm, and the width is 3 cm. The non-woven fabric face mask 1 has a three-layer structure composed of an inner layer, a middle layer, and an outer layer, wherein both the inner layer and the outer layer are polypropylene non-woven fabrics, and the middle layer is a polypropylene melt-blown fabric.

[0023] It includes a sterilization package, and the sterilization package is a degradable paper-plastic package.

[0024] A mask upper edge built-in shaping metal strip is provided at the upper edge of the non-woven fabric face mask. When a doctor or nurse wears it for a patient, the shaping functions of the mask lower edge built-in shaping metal strip and the mask upper edge built-in shaping metal strip can be used to adjust the distance between the transparent film and the eyes on the premise of keeping the mask in close contact with the patient's face, so that patients with different eye, nose, and face contours can wear it conveniently and comfortably.

[0025] The disposable eye mask for preventing splashing during dental treatment of the present invention adopts a medical non-woven fabric, and thickened ear straps with a specification of 6 mm are used on both sides. The total length of the outer extension width on the upper side of the eye mask is 18 cm, the total length of the middle outer extension is 20 cm, and the lower edge shrinks into a circular arc from the center of the cheekbone to both sides. The distance from the eyebrow bone to the center of the cheekbone is 7 cm, the distance from the center of the eyebrow to the nose bridge is 6 cm, and the width at the nose bridge is 3 cm. The diameter of the transparent part: the length is 16 cm and the width is 3 cm.

[0026] The present invention replaces the existing plastic goggles that are used by one person at a time and wiped and disinfected by one person at a time with a disposable anti-spray protective eye mask under visual inspection. The disposable eye mask is designed as follows: in terms of material, non-woven fabric used for disposable medical masks is selected for the outer periphery of the eye socket. The eye mask body has a three-layer structure, which is divided into: the inner and outer layers are polypropylene (PP) non-woven fabrics, and the middle layer is polypropylene (PP) melt-blown fabric. The lower edge and both sides of the eye mask are wrapped with soft metal wire / fine iron wire by polyethylene (PE). All are combined with anti-allergy materials. And nano breathable holes are used around the eye mask to ensure the breathability of the eye mask, and at the same time, it can effectively prevent the spray from penetrating into the inner layer of the eye mask. Eye mask strap: The ear part is made of widened elastic spandex material. The nose part is designed into a shallow U shape to reduce tension. The lower edge and both sides of the eye mask are provided with embedded soft metal wires to make the non-woven fabric fit the face and nose better, and the eye mask can also be supported to increase the distance between the transparent film and the eyes. The sense of security and comfort of the patient when wearing during treatment is increased. Most importantly, for the eye part, from the eye socket to the eyes inward, a thickened type of transparent composite film material of a disposable medical sterilization paper-plastic bag is selected: when the hospital screens the sterilization paper-plastic bag, the performance of the product should be ensured: suitable for high-pressure steam sterilization of medical devices, sterilization packaging of low-temperature ethylene oxide EO. Ensure the qualification of instrument sterilization. Select materials that are not easily punctured by sharp instruments. The transparent film material of the disposable sterilization paper-plastic bag is: PET / CPP composite film, and the main components of the film are polypropylene and polyester. Core characteristics and advantages, PET provides tensile strength, CPP enhances flexibility, and has excellent moisture barrier properties. It can withstand 120°C to 135°C, is suitable for high-pressure sterilization, does not deform, does not melt. The shelf life is long.

[0027] The shape of a disposable anti-spray eye mask for dental treatment according to the present invention: on the basis of the disposable protective mask commonly sold in the market, a high-transparency material of PET (polyester) / CPP (cast polypropylene) is added from the eye socket to the eyes inward. It has strong heat resistance and good moisture barrier performance and is commonly used in packaging materials. PET / CPP is a water vapor barrier composite film, combined with an anti-fog coating, which avoids the disadvantages of repeated wiping of the goggles, such as wear, decreased transparency, and unsealed eye circumference. It remains light, and the patient is more comfortable to wear during treatment. The nose part is designed into a shallow U shape to make it fit the bridge of the nose better.

[0028] The material of a disposable anti-spray eye mask for dental treatment according to the present invention: The material of disposable medical masks is selected, which ensures that patients can use one for one person and replace it one by one during dental treatment, and can reduce the risk of cross-infection caused by repeated use at the hospital infection level.

[0029] The economic consumption of a disposable anti-spray eye mask for dental treatment according to the present invention: The cost is low. Although the goggles are not very expensive, due to repeated wiping with alcohol-containing disinfectant wipes, it is easy to cause the mirror surface to become blurred and the replacement is frequent. Therefore, compared with the goggles that can be used multiple times, a disposable anti-spray eye mask for dental treatment according to the present invention will not bring too high a cost as a whole.

[0030] During dental treatment, such as teeth cleaning, after teeth cleaning, the teeth are rinsed and medicated with 3% hydrogen peroxide, and when filling teeth or using a high-speed turbine, droplets and sprays will be generated, which may splash into the eyes of patients or medical staff. Therefore, the main function of this eye mask is to prevent these splashing liquids from entering the eyes of patients or medical staff and protect the eye safety of patients during dental treatment.

[0031] The designed disposable anti-splash eye mask for dental treatment belongs to the field of medical protective articles, especially the protective equipment used in dentistry.

[0032] Uses of the disposable anti-splash eye mask for dental treatment: mainly during the treatment of oral diseases, it protects the eyes of patients and medical staff from splashing of droplets, blood, liquid medicine, saliva and other liquids. It isolates the aerosol environment generated by high-speed handpieces and ultrasonic scalers, reduces viruses, and avoids occupational exposure infections (such as conjunctivitis, hepatitis B, etc.).

[0033] Functions of the disposable anti-splash eye mask for dental treatment: The function is a physical barrier. Hospital infection control is emphasized, so preventing cross-infection is very important. During invasive operations such as implanting and tooth extraction, it prevents accidental scratching or entry into the eyes by small sharp instruments. At the same time, it can improve the comfort of patients and enable visual observation of the doctor's operation, providing a sense of security for patients with anxiety and claustrophobia during treatment. It meets the mandatory requirements for "four-handed operation" protection in the "Technical Specification for Disinfection of Oral Medical Instruments in Medical Institutions".

[0034] Regarding the high-performance bonding of the composite film: The outer layer of the PET / CPP composite film uses polyethylene terephthalate (PET), providing high transparency and scratch resistance. The inner layer is cast polypropylene (CPP), with excellent heat-sealing properties and high-temperature resistance, suitable for high-temperature sterilization scenarios and low-temperature ethylene oxide (EO) sterilization.

[0035] Regarding the anti-fog and hydrophobic coatings: Drawing on the PET film technology of Delos, through a nano-silica coating or hydrophilic polymer material, the anti-fog function of the lens is achieved; at the same time, a fluorinated hydrophobic coating is added to enhance the anti-permeability to blood and saliva.

[0036] Regarding environmental protection and biocompatibility: Biodegradable materials (such as PLA+PBAT composite layer) are introduced in the design to reduce medical waste pollution, and at the same time ensure that the materials meet medical-grade safety standards (such as FDA certification).

[0037] Regarding the sealing and anti-splash design in the structural design optimization: Fully enclosed edge: Improve the shape design of the disposable VR eye mask to better fit the facial and nasal contours and prevent liquid from seeping in from the edge.

[0038] Regarding lightweight and conformability in structural design optimization: An embedded soft metal wire is provided at the lower edge of the three-dimensional formed blindfold in combination with the blindfold, making the non-woven fabric fit the face and nose more closely. It adapts to different face shapes, reduces the pressure during long-term wear, and improves comfort.

[0039] Regarding the upgrade of the composite process in the production process: Among them, the dry composite technology uses food-grade polyurethane adhesives to ensure firm adhesion between the PET and CPP layers, while avoiding chemical residues. Among them, the extrusion composite process directly coats the surface of PET by melting CPP, reducing the use of glue and improving environmental protection and production efficiency.

[0040] Regarding sterilization and packaging optimization: Ethylene oxide (EO) or irradiation sterilization is used to ensure the sterility of disposable blindfolds, and biodegradable paper-plastic packaging is used to reduce the environmental burden.

[0041] Regarding application scenarios: Among them, multi-scenario adaptation is applicable to high-splash risk scenarios such as oral diagnosis and treatment (such as high-speed handpiece operation, ultrasonic scaling), and operating room protection, taking into account both protection and operation convenience. Among them, compatibility with other protective equipment includes seamless connection with masks and hoods to form a comprehensive protection system, avoiding the problem of vision obstruction caused by the superposition of multiple protective equipment.

[0042] Regarding sustainable materials, a fully bio-based PET / CPP composite film can be developed to improve recyclability and degradation efficiency.

[0043] In summary, the PET / CPP composite film protective blindfold can seek breakthroughs in materials, structures, functions, and production processes, providing a safer, more efficient, and more user-friendly protection solution for high-risk scenarios such as oral treatment.
