Description

Technical Field

[0001] The invention relates to the technical field of anesthesia masks, in particular to an anesthesia mask using nano antibacterial materials. Background Art

[0002] An anesthesia mask is a medical device used to administer general anesthesia to patients. It typically consists of a mask with an adapter and a connecting tube. The anesthesia mask mixes oxygen and anesthetics and delivers them through the patient's respiratory tract to their lungs. This can be accomplished using a fixed-ratio system, where the ratio of oxygen and anesthetics delivered through the mask is fixed.

[0003] However, the existing anesthesia masks have the following problems during use: the anesthesia mask has high requirements for the sealing of the mask during use, and inadequate sealing may cause the anesthetic gas to leak out. The existing method of ensuring the sealing of the anesthesia mask is mainly to seal the mask by fitting the sealing rubber ring on the edge of the mask to the patient's face. However, due to the patient's facial blemishes or sunken cheeks or protruding cheekbones, the sealing may be poor. Usually, the anesthesiologist needs to increase the tightness between the mask and the patient's face by pressing with his hands when anesthetizing the patient, which is cumbersome. In addition, when the patient wears the anesthesia mask, the water vapor exhaled from the patient's mouth and nose will condense into water droplets and drip on the patient's face. In severe cases, it may enter the trachea through the patient's respiratory tract, posing a hidden danger to the patient's life safety. There is a lack of corresponding treatment methods. Therefore, it is necessary to design corresponding technical solutions to solve the existing technical problems. Summary of the Invention

However, due to the patient's facial blemishes or sunken cheeks and protruding cheekbones, the sealing is poor. Usually, the anesthesiologist needs to increase the tightness between the mask and the patient's face by pressing with his hands when anesthetizing the patient, which is cumbersome. In addition, when the patient wears the anesthesia mask, the water vapor exhaled from the patient's mouth and nose will condense into water droplets and drip on the patient's face.

DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-4The present invention provides a technical solution: an anesthesia mask using nano-antibacterial material, comprising a mask body, an antibacterial mask liner and a sealing outer ring, the mask body comprising a mask body 1 and an air inlet port 2 mounted on the surface of the mask body 1, an inner cavity 3 is formed inside the mask body 1, the antibacterial mask liner is built into the inner cavity 3, the antibacterial mask inner cover 4 comprises an inner cover 4, an antibacterial absorbent pad 5, a bottom ring 6 and a double-sided adhesive tape 7, the inner cover 4 is built into the inner cavity 3 and a docking port 8 is opened at the upper end, an annular sealing gasket 9 is fixed at the docking port 8, the docking port 8 is located at the lower end of the air inlet port 2 and the two are sealed by the annular sealing gasket 9, the antibacterial absorbent pad 5 is connected to the lower edge of the inner cover 4, the bottom ring 6 is fixed to the bottom of the antibacterial absorbent pad 5, and the double-sided adhesive tape 7 is provided. There are several groups of them evenly distributed on the edges of the inner cover 4 and the bottom ring 6, double-sided adhesive tape 7 is attached to the inner wall of the mask body 1, and the sealed outer ring is fixed to the edge of the mask body 1. The sealed outer ring includes a negative pressure adsorption ring 10, a connecting tube 11, a suction air bag 12 and a water-absorbing outer pad 13. The negative pressure adsorption ring 10 is fixed to the bottom of the mask body 1 and a suction cavity 14 is formed inside. The connecting tube 11 is connected to the negative pressure adsorption ring 10, and the end of the suction air bag 12 is inserted into the connecting tube 11. The water-absorbing outer pad 13 is fixed to the periphery of the negative pressure adsorption ring 10. The designed anesthesia mask can effectively solve the problem that the water vapor exhaled by the patient's mouth and nose will condense into water droplets and drip on the patient's face, and can greatly improve the sealing of the anesthesia mask during wearing.

[0022] Further improvement, such as Figure 2 As shown, the inner wall of the inner cover 4 is processed to form several groups of liquid guide channels 15, which are radially distributed with the docking port 8 as the center. The upper end of the liquid guide channel 15 is connected to the docking port 8 and the lower end is located at the antibacterial absorbent pad 5. This design makes it easy to guide the water droplets adhering to the inner cover 4.

[0023] Further improvement, such as Figure 4 As shown, spacing grooves 16 are formed on both sides of the liquid guiding channel 15. The spacing grooves 16 are convex structures, and the liquid guiding channel 15 is concave structure. The height of the spacing grooves 16 is greater than the height of the liquid guiding channel 15. This design makes it easy to guide the water vapor and water droplets adhering to the inner wall of the inner cover 4 and flow them into the liquid guiding channel 15. The water is introduced into the antibacterial absorbent pad 5 through the liquid guiding channel 15 for absorption, thereby improving the dryness of the inside of the mask.

[0024] Further improvement, such as Figure 1 As shown, the antibacterial absorbent pad 5 is made of nano-silver antibacterial material and its surface is processed into a porous structure. The antibacterial absorbent pad 5 is attached to the inner wall of the mask body 1. Nano-silver is a new antibacterial material developed based on nanotechnology. It is composed of metallic silver particles with a particle size of 1nm-100nm. Since silver has a strong bactericidal ability and is safe to the human body at low concentrations and is not easy to produce drug resistance, the antibacterial absorbent pad 5 is used to improve the antibacterial property of the anesthesia mask.

[0025] Further improvement, such as Figure 4 As shown, the negative pressure adsorption ring 10 has an annular structure and matches the specifications of the bottom of the mask body 1. The negative pressure adsorption ring 10 is made of rubber material and has leaf-shaped structures on both sides. This design makes it easy for the negative pressure adsorption ring 10 to be adsorbed on the patient's face.

[0026] Further improvement, such as Figure 1 As shown, the suction airbag 12 includes an airbag ball 17 and a cannula 18 fixed to one side of the airbag ball 17. The cannula 18 is correspondingly inserted into the connecting tube 11. When negative pressure adsorption of the negative pressure adsorption ring 10 is required, the medical staff first presses the airbag ball 17 to discharge the internal gas, and then inserts the cannula 18 into the connecting tube 11. The gas in the suction chamber 14 is sucked out through the airbag ball 17 and negative pressure is generated, thereby achieving the purpose of negative pressure adsorption.

[0027] Specifically, the water-absorbent outer pad 13 is made of sponge material with a thickness of 3mm-5mm, the width of the water-absorbent outer pad 13 is 1cm-2cm, and the surface of the water-absorbent outer pad 13 is processed into a honeycomb structure. This design method facilitates the water-absorbent outer pad 13 to absorb water dripping on the water-absorbent outer pad 13, and enables the water-absorbent outer pad 13 to be better attached to the patient's face, thereby achieving the purpose of further sealing the anesthesia mask.

[0028] During use: Before anesthetizing the patient, the medical staff will place the antibacterial mask liner inside the mask body and fix it with double-sided adhesive tape 7. At the same time, the docking interface 8 will dock with the lower end of the air inlet port 2 and seal it with an annular sealing gasket 9. Then the anesthesia mask will be covered on the patient's mouth and nose. The water vapor exhaled by the patient during breathing will form water droplets on the antibacterial mask liner. Under the influence of gravity, the water droplets will be introduced into the absorbent pad of the antibacterial mask liner to ensure the dryness of the mask. In addition, when the anesthesia mask is put on, After putting on the mask, the medical staff temporarily presses the anesthesia mask so that the negative pressure adsorption ring 10 is in full contact with the patient's face. Then the medical staff presses the airbag ball 17 to expel the internal gas, and then inserts the cannula 18 into the connecting tube 11. The airbag ball 17 is used to draw the gas in the suction chamber 14 out and generate negative pressure, thereby achieving the purpose of negative pressure adsorption. Finally, water is dripped onto the water-absorbing outer pad 13, and the water-absorbing outer pad 13 is attached to the patient's face. The downward pressure on the anesthesia mask can be abandoned, and a better sealing effect can be achieved.
