Technical Field

[0001] This utility model relates to the field of anesthesia breathing mask technology, specifically a breathing mask device for surgical anesthesia. Background Technology

[0002] Nowadays, anesthesia techniques are widely used in medical surgery. The simplest and most effective method is to add anesthetic drugs into a ventilator, allowing the patient to be deeply anesthetized by inhaling the anesthetic drugs along with oxygen. The advantage of this method is that the anesthesia time is controllable and the anesthetic effect is good.

[0003] The existing anesthesia mask's fixing straps may cause significant pressure or discomfort to the patient's head. Furthermore, the patient inhales dry gas, which can irritate the respiratory tract over a long period, increasing the risk of respiratory complications. In addition, the mask is not easily adjustable to accommodate different facial contours and sizes, leading to the risk of air leakage when using it. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a respiratory mask device for surgical anesthesia, which solves the problems that existing respiratory masks cannot be adjusted to follow the patient's facial contours and that the patient inhales dry gas, which can lead to respiratory complications if inhaled for a long time.

[0011] Beneficial effects

[0012] This invention provides a breathing mask device for surgical anesthesia. Compared with the prior art, it has the following advantages:

[0013] (1) By setting up the air cushion, air tube and control valve, the inflation and deflation are adopted to better adapt to the facial contours and face sizes of different patients, improve the fit and comfort of wearing, and reduce the risk of air leakage. Through the cooperation between the adjustment rod, pull block, meshing gear and slot plate, medical staff can adjust the connecting block and the first strap up and down, so that the first strap, the second strap and the magnetic sticker can be adjusted, thereby reducing the pressure on the patient's head or face caused by the fixing strap mechanism.

[0014] (2) By combining the detachable water tank with the ring heating wire, the dry gas in the breathing mask can be humidified, thereby reducing the irritation of the respiratory tract by the dry gas. Secondly, the ring heating wire and temperature sensor can monitor the temperature of the heating wire in real time. Then, the current of the heating wire can be automatically adjusted according to the set temperature value to achieve precise temperature control. Moreover, the ceramic fiber used in the ventilation insulation plate has good heat insulation performance, high temperature resistance, good chemical stability, and soft texture, with low skin irritation. It also has a certain degree of breathability, allowing air to circulate freely to a certain extent. The heating wire is a metal wire with a special coating. The surface is made of a smooth material that does not easily adsorb impurities and is corrosion resistant, which facilitates the removal of dirt during cleaning and disinfection. The heating wire and ventilation insulation plate are detachable, which makes it convenient for medical staff to separate the heating wire, ventilation insulation plate and mask body for disinfection and cleaning. As for the filter screen, since the anesthesia device has a filter plate for initial gas filtration, the addition of a filter screen can perform secondary gas filtration. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1:

[0021] Please see Figure 1-3 As shown, this embodiment proposes a respiratory mask device for surgical anesthesia, including a mask body 1, an air cushion 2 fixedly attached to the outer wall of the mask body 1, an air tube 3 fixedly attached to one side wall of the air cushion 2, a control valve 4 movably connected to the outer wall of the air tube 3, connecting rings 5 ​​fixedly attached to the left and right sides of the mask body 1, a nasal plug 6 fixedly attached to the front of the mask body 1, an air inlet 7 movably connected to the front of the nasal plug 6, a filter screen 8 fixedly attached inside the air inlet 7, a ventilation port 9 fixedly attached to one side wall of the connecting ring 5, and an adjustment mechanism provided on one side wall of the connecting ring 5. Because the air cushion 2 allows the mask body 1 to cover patients with different face sizes, and the addition of the air cushion 2 can reduce air leakage from the mask body 1, and the addition of the filter screen 8 can perform secondary filtration of the gas from the anesthesia box, thereby reducing the amount of gas inhaled by the patient and preventing respiratory tract infections.

[0022] The adjustment mechanism includes a connecting rod 10, which is positioned on one side wall of the connecting ring 5. A first rotating ring 11 is rotatably connected to one side wall of the connecting rod 10. The outer wall of the first rotating ring 11 is rotatably connected to the first rotating ring 11. An adjustment rod 12 is fixedly connected to one side wall of the first rotating ring 11. A pull block 13 is movably connected to one side wall of the adjustment rod 12. The pull block 13 allows for adjustment of the meshing gear 14 and the slot plate 15, enabling medical personnel to adjust the mechanism according to the size of the patient's face.

[0023] A meshing gear 14 is fixedly connected to one side wall of the pull block 13. A slot plate 15 is provided on the outer wall of the pull block 13. A sliding groove 16 is opened inside the slot plate 15. A connecting block 17 is fixedly connected to the upper surface of the slot plate 15. A first strap 18 is movably connected to one side of the connecting block 17. Because of the use of the sliding groove 16, medical staff need to pull the pull block 13 to adjust the connecting block 17 up and down, thereby adjusting the position of the first strap 18.

[0024] A second rotating ring 19 is movably connected to one side of the connecting ring 5. A second strap 20 is fixed to one side wall of the second rotating ring 19. A magnetic adhesive 21 is movably connected to one side wall of the second strap 20 and the first strap 18. Due to the use of the magnetic adhesive 21, the first strap 18 and the second strap 20 can fit together, thereby making the mask body 1 fit the patient's face.

A sealing port 24 is fixed to one side wall of the temperature sensor 23. An annular heating wire 25 is movably connected inside the mask body 1, and the annular heating wire 25 is interconnected with the temperature sensor 23. Due to the cooperation between the detachable water tank 22 and the annular heating wire 25, the annular heating wire 25 can heat the water in the detachable water tank 22, thereby turning the water into mist, thus humidifying the dry gas. Since the annular heating wire 25 is interconnected with the temperature sensor 23, the annular heating wire 25 can be controlled to achieve a suitable temperature.

[0026] The mask body 1 has two pairs of slot blocks 26 connected internally. A ventilation and heat insulation plate 27 is fixed to one side of the slot block 26. An observation window 28 is fixed inside the ventilation and heat insulation plate 27. Since the ventilation and heat insulation plate 27 is connected to the inside of the mask body 1 through the slot block 26, medical staff can remove the ventilation and heat insulation plate 27 from the mask body 1 to disinfect and clean it. The observation window 28 allows medical staff to observe the patient's facial expression, lip color, etc. during the operation and detect abnormalities in time.

[0027] In use, medical staff use the pull block 13 to engage the meshing gear 14 and the slot plate 15, thereby moving the connecting block 17 up and down. The medical staff adjusts the size according to the patient's face size. The magnetic adhesive 21 is used to attach the first strap 18 and the second strap 20 to cover the patient's face with the mask body 1. Gas is sent into the air cushion 2 through the air tube 3 and left in the air cushion 2 through the control valve 4. The annular heating wire 25 is activated to heat the water in the detachable water tank 22, turning the water into water vapor. The anesthetic gas is sent in through the air inlet 7, and the water vapor enters the patient's body together with the anesthetic gas. The medical staff observes the patient's face through the observation window 28.
