Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an anti-fog mask for operating room nurses. Background Art

[0002] During modern medical surgeries, nurses need to wear protective masks in some operations to prevent themselves from occupational exposure. However, if the mask is worn for too long or the temperature difference is large, when the nurse breathes, fog is likely to form on the mask, and this fog will have a certain impact. Therefore, an anti-fog mask for operating room nurses is needed to eliminate this adverse effect.

[0003] Chinese Patent CN214283416U discloses an anti-fog mask for operating room nurses, which includes a bracket, threaded holes, bolts, a mask, a buffer pad, and a first mirror frame. One side of the first mirror frame is movably connected with a hinge, and the first mirror frame is movably connected with a second mirror frame through the hinge. One end of the first mirror frame is fixedly connected with a nose bridge frame. Inside the mask, an outer layer of glass, a polyurethane interlayer, a PVB interlayer, and an inner layer of glass are sequentially arranged from left to right. The main advantage of this utility model is to provide an anti-fog mask for operating room nurses. This device provides an anti-fog structure. When in use, insert the bolt into the threaded hole and tighten the bolt to assemble and connect the mask with the bracket. The nurse can hang the second mirror frame on the ears and the nose bridge frame on the nose. When the mask is not in use, the second mirror frame can be folded with the first mirror frame through the hinge, which is convenient for storing the mask and improves the use efficiency of the device. However, there are still defects that can be improved:

[0004] 1. In this utility model, the first mirror frame is fixedly connected to the bracket, and then the first mirror frame and the second mirror frame are hinged together. However, it should be noted that the head sizes of each nurse are different. If the first mirror frame is fixed to the bracket, when the nurse wears this mask with an inappropriate size for a long time, it is very easy to cause discomfort to the head.

[0005] 2. In this utility model, a micro fan and a storage battery are arranged inside the buffer pad to prevent fog on the mask. However, it should be noted that the micro fan and the storage battery have a certain weight. When the nurse wears a heavier mask for a long time, it is very likely to cause discomfort to the neck; at the same time, using the fan to blow away the fog may very likely affect the line of sight while blowing.

[0030] The following further details the present utility model in conjunction with the attached drawings.

[0031] The working principle of the present utility model is as Figures 1 - 5As shown in the figure, an anti-fog mask for operating room nurses includes a first fixing block 1. First, rotating frames 11 are fixedly connected to both sides of the middle part of the front end of the first fixing block 1. A rotating block 12 is rotatably connected to the adjacent sides of the two rotating frames 11. Immediately, an anti-fog mask 13 is fixedly connected to the bottom end of the rotating block 12. Here, a ventilation device 16 is arranged at the lower part of the rear end of the anti-fog mask 13. At the same time, an observation hole 14 is opened at the upper part of the front end of the anti-fog mask 13. Nurses can view the outside situation through the observation hole 14. It should be noted that the observation hole 14 is sufficient for nurses to observe the patient's condition. Immediately, a transparent film 15 used in cooperation with the observation hole 14 is fixedly connected to the front end of the anti-fog mask 13. An anti-fog coating is arranged on the rear part of the transparent film 15, and the anti-fog coating further prevents the transparent film 15 from fogging. Thus, the achieved effect is that when the user rotates the rotating block 12 to a suitable position, the anti-fog mask 13 will rotate together with the rotating block 12, so that the eyes are located behind the observation hole 14, and then the mouth and nose are located inside the ventilation device 16. Immediately, fixing plates 5 are arranged on both sides of the first fixing block 1. Grooves 6 are opened on the adjacent sides of the two fixing plates 5. A number of longitudinally arranged first springs 10 are fixedly connected to the side walls of the two grooves 6. The adjacent ends of the two first springs 10 are fixedly connected to a second fixing block 9. Then, grooves 7 are opened on the front and rear walls of the two grooves 6. It should be noted that the grooves 6 and the grooves 7 are connected. Then, sliding blocks 8 are slidably connected to the front and rear grooves 7. The adjacent sides of the front and rear sliding blocks 8 are fixedly connected to the second fixing block 9. At the same time, connecting blocks 3 are fixedly connected to the front ends of the adjacent sides of the two fixing plates 5. At the same time, chutes 2 are opened on both sides of the first fixing block 1. The connecting blocks 3 are slidably connected to the chutes 2. It should be noted that the two chutes 2 and the connecting blocks 3 are connected to each other through fixing devices 4. Thus, the achieved effect is that first, the connecting blocks 3 are slid from the chutes 2 to the specified positions, and then the connecting blocks 3 are fixed through the fixing devices 4. Immediately, the two second fixing blocks 9 are moved towards the separated sides, and then the mask device is brought to the head. Then, the first springs 10 will push the second fixing blocks 9 to press on the head, completing the fixation of the mask on the head.

[0032] The above-mentioned various structures together constitute the general appearance structure of an anti-fog mask for operating room nurses of the present invention.

[0033] To further explain the specific working principle of a fog-proof mask for operating room nurses of the present utility model, the ventilation device 16 includes a first blocking block 1601 fixedly connected to the rear end of the fog-proof cover 13. The first blocking block 1601 is located below the observation hole 14. Then, a second blocking block 1605 is arranged below the first blocking block 1601. Immediately, both ends of the adjacent sides of the first blocking block 1601 and the second blocking block 1605 are fixedly connected with third blocking blocks 1609. Here, the front ends of the third blocking blocks 1609 on both sides and the front end of the second blocking block 1605 are fixedly connected to the rear end of the fog-proof cover 13. Immediately, a plurality of ventilation holes 1607 are formed in the middle of the top end of the second blocking block 1605, and a filter block 1608 is arranged at the bottom end of the second blocking block 1605. It is worth noting that the ventilation holes 1607 and the filter block 1608 are used in combination. A second silicone strip 1606 is fixedly connected to the rear side of the top end of the second blocking block 1605. At the same time, a third silicone strip 1610 is fixedly connected to the adjacent sides of both ends of the third blocking blocks 1609. Immediately, an arc-shaped groove 1602 is formed in the top end of the first blocking block 1601. The arc-shaped groove 1602 is used to cooperate with the nurse's nose. A nose pad 1603 is fixedly connected to the top end of the first blocking block 1601. The nose pad 1603 further protects the nurse's nose and does not allow the gas exhaled from the nose to be discharged onto the transparent film 15. At the same time, it is worth noting that a silicone pad is arranged on the nose pad 1603 to reduce the friction of the nose pad 1603 on the user's nose. A first silicone strip 1604 is fixedly connected to the bottom end of the first blocking block 1601. It is worth noting that the first silicone strip 1604, the second silicone strip 1606, and the third silicone strip 1610 form a rectangular sealing area, and the gas will not leak from the connection, but only go out through the ventilation holes 1607.

[0034] The technical effect achieved by the technical solution composed of the above technical features is that when the fog-proof cover 13 rotates to a suitable area, first, the arc-shaped groove 1602 and the nose pad 1603 will cover the nurse's nose part, and the first silicone strip 1604, the second silicone strip 1606, and the third silicone strip 1610 will abut against the nurse's face. At this time, the gas exhaled by the nurse from the nose and mouth will be sealed by the first silicone strip 1604, the second silicone strip 1606, and the third silicone strip 1610, and then discharged from the ventilation holes 1607 at the bottom end of the second blocking block 1605, and the filter block 1608 provides the function of filtering harmful gases.

[0035] In order to further explain the specific working principle of the anti-fog mask for operating room nurses of the utility model, the above-mentioned fixing device 4 includes a plurality of fixing grooves 402 opened at the front end of the connecting block 3, and the fixing block 1 is provided with a fixing hole 401 used to cooperate with the fixing groove 402, and a groove three 403 is provided on the top wall and the bottom wall of the fixing hole 401, and then, a positioning shaft 406 is slidably connected in the fixing hole 401, and the rear part of the positioning shaft 406 is inserted into the fixing groove 402, and a baffle 404 is fixedly connected to the upper and lower sides of the middle part of the outer periphery of the positioning shaft 406, and the baffle 404 is slidably connected in the corresponding groove three 403, and at the same time, a spring two 405 is fixedly connected to the front walls of the upper and lower grooves three 403, it is worth noting that the rear end of the spring two 405 is fixedly connected to the baffle 404, and finally, the front end of the positioning shaft 406 passes through the fixing hole 401 and is fixedly connected to a pull-out block 407.

[0036] The technical effect achieved by the technical solution composed of the above technical features is: when stationary, the positioning shaft 406 limits the position of the connecting block 3 in the slide groove 2; when the connecting block 3 needs to be pulled out of the slide groove 2 to a suitable position, the user first pulls the pull-out block 407 outward, and the positioning shaft 406 fixedly connected to the pull-out block 407 moves forward with the pull-out block 407, and when the pull-out block 407 moves forward, the baffle 404 fixedly connected to the pull-out block 407 moves forward in the groove 3 403 When the baffle 404 moves forward, the second spring 405 is also compressed forward. Then, after the user pulls the connecting block 3 to the specified position, the fixing hole 401 is aligned with the next fixing slot 402. Then, the user releases the pull-out block 407, and the second spring 405 restores the baffle 404 to its original position, and the baffle 404 restores the positioning shaft 406 to its original position. At this time, the rear part of the positioning shaft 406 returns to the fixing slot 402, and the fixing is completed. The positioning shaft 406 once again limits the position of the connecting block 3 in the slide slot 2.

[0037] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.

[0038] In addition, the electrical components appearing in this article are all connected to the external main controller and 220V AC power, and the main controller can be a conventional known device that controls a computer, etc. The specific implementation method of the present disclosure omits the detailed description of known functions and known components.
