Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more particularly to a new anesthesia mask assembly for clinical use. Background Art

[0002] The anesthesia mask is mainly composed of core components such as the mask body, connecting tube and airbag. The mask body is the part that contacts the patient's face and is usually made of transparent silicone or plastic. These materials have good flexibility and durability, can fit the patient's facial contours, and ensure the effective delivery of anesthetic gas and oxygen. The connecting tube is responsible for connecting the mask to the anesthesia machine or oxygen supply equipment. It is usually made of medical-grade plastic or rubber and has sufficient flexibility and strength to adapt to different usage environments and operating requirements. The airbag is another important component of the anesthesia mask. It is used to adjust the gas pressure in the mask to ensure smooth breathing for the patient. The airbag is usually made of soft and durable materials such as PVC, and can be inflated and deflated according to the patient's breathing needs.

[0003] Anesthesia masks may also include some auxiliary components, such as one-way valves, fixing rings or headbands. One-way valves can ensure that anesthetic gases and oxygen can only flow in one direction, preventing the risk of gas backflow and cross infection. Fixing rings or headbands are used to fix the mask to the patient's face to prevent the mask from falling off or shifting during anesthesia. These auxiliary components can improve the comfort and sealing of the anesthesia mask, thereby ensuring the safety and effectiveness of the anesthesia process. In addition, depending on the specific anesthesia needs and patient conditions, the anesthesia mask may also be equipped with other special components or accessories to meet the diverse needs of clinical use.

[0004] For patients with thin faces or loose facial muscles due to old age, the mask may not fit the face tightly, and the adaptability to patients with different face shapes is poor, resulting in leakage of anesthetic gas and affecting the anesthesia effect. Leakage will not only reduce the concentration of anesthetic gas, but also prolong the anesthesia cycle, increase the patient's breathing difficulties, and even cause harm to the patient.

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0029] Embodiment 1:

[0030] See also Figure 1-6 A new type of clinical anesthesia mask assembly comprises an outer ring 1, a pair of telescopic brackets 5 and an adjusting block 8. The side end of the outer ring 1 is fixedly connected to an outer mask 2, the inner end of the outer mask 2 is fixedly connected to an inner mask 3, the inner mask 3 is fixedly connected to an inner ring 4 at one end away from the outer mask 2, and the inner ring 4 is located on the inner side of the outer ring 1. Two inner and outer masks are formed by the outer ring 1, the outer mask 2 and the inner mask 3 and the inner ring 4, so as to prevent leakage of anesthetic gas. The pair of telescopic brackets 5 are staggered and fixedly connected, and the telescopic brackets 5 are fixedly connected to the inner wall of the inner mask 3. The pair of telescopic brackets 5 can not only support the mask as a whole, but also control the size of the mask by using the telescopic brackets 5. An interface 6 is fixedly connected, and the interface 6 passes through the inner mask 3. A connecting ring 7 is fixedly connected to the end of the interface 6 away from the telescopic bracket 5. The outer ends of the connecting ring 7 are respectively fixedly connected to a ventilation tube and an anesthesia tube. After the connecting ring 7 is connected to the interface 6, oxygen and anesthetic gas are provided to the mask. An adjusting groove is provided at the inner end of the connecting ring 7. An adjusting block 8 is slidably connected in the adjusting groove. A bolt 9 is rotatably connected to the lower end of the adjusting block 8, and the bolt 9 passes through the connecting ring 7 and extends to the outer end of the connecting ring 7. A rotating block 10 is fixedly connected to the end of the bolt 9 away from the adjusting block 8. An anesthesia hole 11 is provided on the inner wall of the adjusting groove. The bolt 9 is rotated by rotating the rotating block 10, so as to adjust the adjusting block 8, so that the adjusting block 8 slides to change the gas passed.

[0031] The telescopic bracket 5 includes an arc plate 51, which is fixedly connected to the inner wall of the inner mask 3. Telescopic grooves are provided at both the upper and lower ends of the arc plate 51. A tough rod 52 is slidably connected in the telescopic groove, and the tough rod 52 is fixedly connected to the inner ring 4. A spring 53 is fixedly connected between the tough rod 52 and the inner wall of the telescopic groove. By applying pressure to the tough rod 52, the tough rod 52 compresses the spring 53, so that the tough rod 52 slides into the telescopic groove, changing the length of the telescopic bracket 5, thereby changing the size of the mask, so that the mask can better fit the patient's face.

[0032] The telescopic bracket 5 also includes a piston cylinder 54, which is fixedly connected to the inner wall of the telescopic groove, and a spring 53 is wound around the outer end of the piston cylinder 54. A plurality of air holes are opened at one end of the inner ring 4 away from the inner mask 3, and the plurality of air holes are respectively fixedly connected to the piston cylinder 54 through hoses. Air is exhausted through the movement inside the piston cylinder 54, so that the air holes inhale air, so that the inner ring 4, when it fits the patient's face, uses negative pressure to make it tightly fit against the patient's face, thereby effectively preventing gas leakage.

[0033] The piston cylinder 54 includes a vacuum cylinder 541, which is fixedly connected to the inner wall of the telescopic groove. The inner end of the vacuum cylinder 541 is slidably connected to a piston block 542. The piston block 542 is fixedly connected to one end of the flexible rod 52 close to a support rod 543, and the support rod 543 is fixedly connected to the flexible rod 52. The support rod 543 is squeezed by sliding the flexible rod 52, so that the support rod 543 pushes the piston block 542 to slide in the vacuum cylinder 541.

[0034] A connecting hole is provided on the upper inner wall of the vacuum cylinder 541, and the connecting hole is located above the piston block 542. A plurality of exhaust holes are provided on the lower inner wall of the vacuum cylinder 541. The gas in the vacuum cylinder 541 is discharged from the exhaust holes through the sliding of the piston block 542. When the piston block 542 is pushed, the hose connected to the connecting hole is evacuated, so that the air holes suck the patient's facial skin, so that the mask can fit tightly to the patient's face.

[0035] The adjustment block 8 includes a slider 81, which is slidably connected in the adjustment groove. An exhaust groove 82 is provided at one end of the slider 81 close to the interface 6, and a pair of air inlet holes 83 are provided on the inner wall of the exhaust groove 82. When the slider 81 slides up and down away from the anesthesia hole 11, the anesthetic gas enters the air inlet holes 83 and is discharged into the mask from the exhaust groove 82.

[0036] The regulating block 8 also includes a plug 84, which is fixedly connected to the upper end of the slider 81, and the plug 84 matches the anesthesia hole 11. A vent 85 is provided in the middle of the slider 81. When the slider 81 slides to allow the anesthetic gas to be discharged, the vent 85 slides into the inside of the regulating groove, so that the vent 85 is blocked to prevent gas leakage. When the regulating slider 81 is slid upward, the plug 84 blocks the anesthesia hole 11, so that the anesthetic gas stops continuing to enter the air inlet 83, and the vent 85 is exposed to be connected to the ventilation pipe for oxygen supply, so that the slider 81 is used for adjustment to switch the oxygen supply and the anesthetic gas supply.

[0037] The outer end of the outer ring 1 is fixedly connected with a strap 12, and the middle of the strap 12 is fixedly connected with an adjustment buckle. The mask can be worn on the patient's face through the strap 12, and the size and tightness of the strap 12 can be adjusted by the adjustment buckle to suit different patients.

[0038] The interface 6 and the connecting ring 7 are connected by threaded connection, and sealing gaskets are provided at the connection between the interface 6 and the connecting ring 7 and at the connection between the bolt 9 and the connecting ring 7. The threaded connection can facilitate the installation and disassembly of the connecting ring 7, and the sealing gasket can effectively prevent leakage at the connection.

[0039] The outer ring 1, the inner ring 4 and the plug 84 are all made of silicone material. The silicone material can not only make the outer ring 1 and the inner ring 4 easily deformable to adapt to patients with different face shapes, but also the plug 84 can be better plugged into the anesthesia hole 11 to prevent leakage.

[0040] It can be seen from the above technical solutions that the present invention has the following beneficial effects:

[0041] The present invention adopts silicone material to make the outer ring 1 and the inner ring 4, which can adapt to the facial shapes of different patients, ensure the close fit of the mask, and effectively prevent the leakage of anesthetic gas. The outer ring 1 and the inner mask 3 form a double seal through the cooperation of the internal and external structures, which helps to further reduce the leakage of anesthetic gas. The telescopic bracket 5 includes components such as an arc plate 51 and a tough rod 52, which can adjust the size of the mask to ensure that the mask fits the patient's face closely, improve comfort and prevent air leakage. The piston cylinder 54 and the air hole 11 use the negative pressure principle to make the inner ring 4 closer to the face and effectively prevent gas leakage. The adjustment block 8 is provided with the function of adjusting the airflow. The slider 81 can control the switching between oxygen and anesthetic gas by adjusting the vent 85 and the anesthesia hole 11, providing flexibility for different clinical needs. The interface 6 and the connecting ring 7 are threaded and equipped with a sealing gasket to ensure a stable connection without air leakage, which not only improves the safety and comfort in use, but also improves the convenience and adaptability of operation.
