Description

Technical Field

[0001] This utility model relates to the field of medical protective equipment technology, and in particular to a medical protective face shield. Background Technology

[0002] When performing surgery, cleaning medical equipment, or handling patients at risk of infection, healthcare workers typically need to wear transparent protective face shields to prevent contaminants such as cleaning solutions, droplets, blood, bodily fluids, and secretions from splashing onto their faces.

[0003] Commonly used medical protective face shields typically consist of a transparent face shield and a headband. The headband is placed over the head of the medical staff, and the transparent face shield is placed on the headband to cover the face and neck of the medical staff. In order to reduce the impact on vision when not in use and to avoid the need for repeated removal and wearing, the transparent face shield is usually flip-able and connected to the headband.

[0004] For example, patent document with authorization announcement number CN 211961018 U discloses a medical protective face shield, which can be installed on the outside of a headband frame by flipping up and down. The face shield is arc-shaped and is used to cover the user's face and neck when worn.

[0005] However, the protective face shield described in the aforementioned patent documents cannot limit or fix the face shield that is installed on the outside of the headband frame by flipping up and down during use. Therefore, when the protective face shield is subjected to external force during use, it may flip open unintentionally, thereby reducing the protective effect on the face and neck of medical personnel. Utility Model Content

[0006] This utility model provides a medical protective face shield. The technical problem to be solved is that the transparent face shield can be limited during use to prevent it from accidentally flipping open due to external force.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] A medical protective face shield includes a headband and a transparent face shield. The transparent face shield is arc-shaped, with its concave side close to the headband and able to be flipped up and down to connect with the headband. The transparent face shield can cover the user's face and neck, or flip up to expose the user's face and neck. It also includes a limiting component, which is movably disposed on the headband and can abut against the transparent face shield after being moved, thereby preventing the transparent face shield from accidentally flipping open.

[0009] Compared with the prior art, the present invention achieves at least the following beneficial effects: The medical protective face shield of the present invention uses a movable limiting component to abut against the transparent face shield, preventing the transparent face shield from accidentally flipping open due to external force, thus enhancing the reliability of protection during use. Furthermore, the limiting component can be movably set on the headband, which can not only ensure that the transparent face shield is limited and fixed during use to prevent accidents, but also allow the transparent face shield to be manually flipped when needed, reducing the impact on vision when not in use, and eliminating the need for repeated removal and wearing.

[0018] To address the shortcomings of existing face shields, which can unintentionally flip open due to external force, reducing their protective effect on medical personnel, the inventors, after careful analysis, discovered that the main reason for this problem is that existing protective face shields are typically designed to flip up and down to connect to a headband in order to minimize obstruction of vision when not in use and to avoid repeated removal and replacement. Based on this analysis, the inventors have made structural improvements to the protective face shield.

[0019] like Figure 1-4 As shown, a medical protective face shield of this utility model includes a headband 1, a transparent face shield 2, and a limiting component 3.

[0020] Example 1

[0021] refer to Figure 1-3 The transparent face shield 2 is arc-shaped, with its concave side close to the headband 1 and connected to the headband 1 by flipping up and down. The transparent face shield 2 can cover the user's face and neck, or flip up to expose the user's face and neck. The limiting component 3 is movably set on the headband 1 and can abut against the transparent face shield 2 after movement, thereby preventing the transparent face shield 2 from accidentally flipping open.

[0022] The movable limiting component 3 abuts against the transparent face shield 2 to prevent the transparent face shield 2 from accidentally flipping open due to external force, thus enhancing the reliability of protection during use. Furthermore, the limiting component 3 can be movably set on the headband 1, which can not only ensure that the transparent face shield 2 is limited and fixed during use to prevent accidents, but also allow the transparent face shield 2 to be manually flipped when needed, reducing the impact on vision when not in use, and eliminating the need for repeated removal and wearing.

[0023] In this first embodiment, the limiting component 3 includes a limiting buckle 31 and a spring 32. A regular polygonal locking block 21 is provided at the rotatable connection between the transparent face screen 2 and the headband 1. The limiting buckle 31 is provided with a regular polygonal locking groove 311 that is adapted to the regular polygonal locking block 21. The headband 1 is provided with a sliding groove 11. One end of the limiting buckle 31 is slidably disposed in the sliding groove 11. The spring 32 is disposed in the sliding groove 11, and both ends abut against the headband 1 and the limiting buckle 31 respectively. Under the action of the spring 32, the regular polygonal locking block 21 is locked into the regular polygonal locking groove 311.

[0024] Under the action of spring 32, the regular polygonal locking block 21 is inserted into the regular polygonal locking slot 311, and the limiting buckle 31 can only slide relative to the headband 1, thereby preventing the transparent face shield 2 from accidentally flipping open due to external force during use; at the same time, when the transparent face shield 2 is not needed to block the view, in order to reduce the impact on vision and avoid repeated removal and wearing, the limiting buckle 31 can be pressed to compress the spring 32. At this time, the regular polygonal locking block 21 disengages from the regular polygonal locking slot 311, and the transparent face shield 2 can be manually flipped open as needed, ensuring the reliability of protection and the convenience of use.

[0025] The sliding groove 11 has a rectangular cross-section, and the end of the limiting buckle 31 that can be slidably inserted into the sliding groove 11 has a cross-sectional shape that matches the sliding groove 11. This prevents the limiting buckle 31 from rotating and ensures that the limiting buckle 31 can only slide relative to the headband 1.

[0026] The headband 1 has a sponge pad 12 on the inner side near the transparent face shield 2. The flexible sponge pad 12 can relieve the pressure of the headband 1 on the forehead and is suitable for long-term wear. Optionally, the sponge pad 12 can be detachably connected to the headband 1 by Velcro.

[0027] A colored screen 22 is provided on the inner side of the transparent screen 2. The colored screen 22 can be used to block strong surgical light and protect the eyes of medical staff. Optionally, for ease of use in different situations, the colored screen 22 is magnetically and detachably connected to the transparent screen 2. The colored screen 22 can be installed when needed and removed when not needed; or the colored screen 22 can be slidably connected to the transparent screen 2. When needed, the colored screen 22 can be slid to the eye area and when not needed, the colored screen 22 can be slid down to the bottom of the transparent screen 2.

[0028] The headband 1 has an elastic band 13 at the end away from the transparent face shield 2. The elastic band 13 is designed to be suitable for medical staff with different head sizes and can reduce the risk of falling off.

[0029] When in use, the headband 1 is worn on the head of the medical staff, and the headband 1 is secured by the elastic band 13. The transparent face shield 2 can be flipped down to cover the face and neck of the medical staff. Under the action of the spring 32, the regular polygonal block 21 is inserted into the regular polygonal slot 311, which can prevent the transparent face shield 2 from accidentally flipping open due to external force during use. The inner sponge pad 12 improves wearing comfort. The color screen that can slide up and down on the inner side of the transparent face shield 2 is used to adjust the light transmittance. When it is necessary to lift and open the transparent face shield 2, the regular polygonal block 21 can be disengaged from the regular polygonal slot 311 by pressing the limit buckle 31.

[0030] Example 2

[0031] The transparent face shield 2 is arc-shaped, with its concave side close to the headband 1 and connected to the headband 1 by flipping up and down. The transparent face shield 2 can cover the user's face and neck, or flip up to expose the user's face and neck. The limiting component 3 is movably set on the headband 1 and can abut against the transparent face shield 2 after movement, thereby preventing the transparent face shield 2 from accidentally flipping open.

[0032] refer to Figure 4 In this second embodiment, unlike the first embodiment, the limiting component 3 includes a spring 32, a ratchet 33, and a pawl 34. The ratchet 33 is fixedly installed at the rotatable connection between the headband 1 and the transparent face shield 2. The two ends of the spring 32 abut against the transparent face shield 2 and the pawl 34 respectively. One end of the pawl 34 is hinged to the transparent face shield 2, and the other end is engaged in the ratchet 33 under the action of the spring 32.

[0033] By limiting and fixing the transparent face shield 2 with ratchet 33 and pawl 34, the transparent face shield 2 can be flipped downwards to cover the face and neck of medical staff. However, when flipping upwards, it is restricted by pawl 34. Therefore, it can avoid accidental flipping and opening due to external force on the transparent face shield 2 during use. Compared with the above embodiment 1, whether flipping downwards or upwards, it is necessary to press the limiting buckle 31 to disengage the regular polygonal block 21 from the regular polygonal slot 311 before adjustment. It is more convenient to use.

[0034] The pawl 34 is also equipped with a lever 341, which can disengage the other end of the pawl 34 from the ratchet 33 by pulling the lever 341. The lever 341 makes it easy to pull the pawl 34 to unlock the ratchet 33.

[0035] It should be understood that all the above embodiments are exemplary and not restrictive. Various modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of this utility model should be within the protection scope of this utility model.
