Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to an anesthesia mask with good closing effect and labor saving. Background Art

[0002] The anesthesia mask is a must-have item for general anesthesia and one of the important "weapons" for rescuing patients. It can fit the face seamlessly and can be pressurized for mask ventilation. Its main part is hard and made of disposable medical plastic and cannot be reused.

[0003] During general anesthesia, due to muscle relaxation, the doctor needs to lift the mandible with great effort so that the patient can breathe normally, or insert an oropharyngeal airway into the patient's throat to prevent the patient's tongue from falling back. After general anesthesia, the mask needs to be opened and the oropharyngeal airway needs to be unplugged from the anesthesia mask. Since the oropharyngeal airway needs to be connected to an external threaded tube, the operation process is troublesome. When using the existing anesthesia mask, the doctor needs to press the edge of the mask with both hands to maintain the airtightness of the mask. This process is laborious and one end of the mask will leak if it is slightly relaxed. The bottom of the existing anesthesia mask uses an air cushion to contact the patient's face, and the fit with the face is poor. Especially for the elderly with tooth defects, there is often a large gap between the anesthesia mask and the cheek, which leaks seriously and needs to be filled, which is very inconvenient. Therefore, it is very necessary to design an anesthesia mask with good closure effect and labor-saving, which can be fine-tuned according to the face, has better ventilation and labor-saving operation. Summary of the invention

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0030] See also Figure 1 The present invention provides a technical solution: an anesthesia mask with good closing effect and labor saving, comprising a cover shell 2 and a vent 21 on the top thereof, a pad 7 connected to the bottom of the cover shell 2, a flexible pad 1 provided at the bottom of the pad 7, an oropharyngeal ventilation device 3 provided inside the vent 21, the flexible pad 1 is made of gel material, when the mask fits the patient's face, the flexible pad 1 can be deformed according to the shape of the patient's face, fill the gap between the mask and the face, and improve the fitting performance; the oropharyngeal ventilation device 3 is combined with the anesthesia mask through the vent 21 into an integrated structure, and there is no need to disassemble the oropharyngeal airway separately, which is convenient to use;

[0031] like Figure 2 The outer wall of the vent 21 is correspondingly provided with a hinge support 213, and a forearm pressing device 4 is installed on one side of the hinge support 213.

A telescopic corrugated section 33 is provided on the straight section 32. A screw pipe 34 is connected to one end of the straight section 32. The inner wall of the screw pipe 34 is provided with an internal thread. The outer wall of the screw pipe 34 contacts the inner wall of the vent 21. When the patient is under general anesthesia, the telescopic corrugated section 33 is stretched to extend the bending section 31 into the patient's throat to prevent the tongue root from falling back. When not in use, the telescopic corrugated section 33 can be shortened. The patient can still inhale anesthetic gas through the bending section 31 with the nose. There is no need to lift the patient's lower jaw during general anesthesia, and there is no need to disassemble the oropharyngeal airway. It is suitable for various occasions.

[0034] like Figure 2-4 The inner wall of the vent 21 is evenly provided with a slide groove 211, and the outer wall of the screw tube 34 is evenly provided with a slider 341, the slider 341 cooperates with the slide groove 211, and one side of the slider 341 is evenly provided with a one-way bevel gear 342, and the inner wall of the slide groove 211 is evenly provided with a one-way clamping groove 212, the one-way bevel gear 342 cooperates with the one-way clamping groove 212, the slide groove 211 and the slider 341 are preferably arranged to be six evenly distributed on the circumference, and the slider 341 is inserted into the slide groove 211 during assembly, so that the bending section 31 can face the correct position, and the one-way bevel gear 342 continuously slides into the one-way clamping groove 212 during the insertion process, and the one-way bevel gear 342 is similar to a ratchet structure to prevent reverse slipping, and the installation process is convenient and the direction is accurate;

[0035] like Figure 1 , 2 and 6, an air inlet pipe 11 is evenly installed on the top of the pad 7, a cavity is opened inside the flexible pad body 1, and a partition 12 is arranged between the cavities, the partition 12 divides the cavity into multiple parts, one end of the air inlet pipe 11 is connected with the air chamber, a one-way valve 111 is arranged inside the air inlet pipe 11, and an air pressure adjustment component 6 is arranged on the top of the pad 7, the air inlet pipe 11 is used to pass gas to adjust the air pressure, when the pressure in the cavity is high, the bottom of the flexible pad body 1 is deformed downward to fill the gap with the patient's face, the one-way valve 111 is used to prevent air leakage in the cavity, and the one-way valve 111 can be opened to inflate the interior, the air pressure adjustment component 6 is used to ventilate the cavity to adjust the pressure, and multiple cavities can make the flexible pad body 1 fit the patient's face more closely;

[0036] like Figure 5-6 The air pressure adjustment component 6 includes an annular shell 61, which is a hollow structure, and a plurality of partitions 611 are installed inside the annular shell 61. The partitions 611 divide the annular shell 61 into a plurality of air chambers, and the bottom of the air chamber is connected with an air outlet nozzle 64, and the air outlet nozzle 64 is adapted to the air inlet pipe 11. A piston rod 62 is slidably inserted inside the annular shell 61, and a spring 63 is sleeved on the outside of the piston rod 62. A flange is provided on the top of the piston rod 62, and a piston 621 is connected to one end of the piston rod 62. The shape of the piston 621 is adapted to the air chamber. When the mask is fitted to the patient's face, especially when facing the face, For an elderly person with cheek defects, if there is still a gap on the contact surface, the annular shell 61 is installed on the top of the pad 7, so that each air outlet nozzle 64 is plugged into each air inlet pipe 11, and then the piston rod 62 vertically above the gap is pressed, one end of which drives the piston 621 to move and squeezes the air in the air chamber into the cavity of the flexible pad body 1 through the air outlet nozzle 64. The spring 63 is used to restore the piston 621 to its initial position. When adjusting the air pressure, only the piston rod 62 at the corresponding position needs to be pressed, which is easy to operate. After the adjustment, the annular shell 61 can be removed. The anesthesia mask itself is disposable, but the annular shell 61 can be used repeatedly, saving costs.

[0037] like Figure 1 , correspondingly, accommodating grooves 13 are opened on both sides of the pad 7, and a thumb auxiliary buckle 5 is installed inside the accommodating groove 13. The cross-section of the thumb auxiliary buckle 5 is C-shaped, and a protrusion matching the cross-section of the accommodating groove 13 is provided at the bottom thereof. When the doctor presses the edge of the mask, the side of the thumb contacts the inner wall of the C-shape for easy positioning. The bottom of the thumb contacts the bottom of the C-shape to increase the force point, fits the shape of the thumb, and is easy to operate. When fine-tuning the position, it is only necessary to move the thumb auxiliary buckle 5 inside the accommodating groove 13 to fine-tune its position to adapt to different hand shapes.
