Description

Technical Field

[0001] The present invention relates to the technical field of respiratory assistance equipment, and in particular to a mask for alleviating respiratory alkalosis. Background Art

[0002] A mask used to relieve respiratory alkalosis is a medical assistive device designed specifically for patients with respiratory alkalosis. Respiratory alkalosis is usually caused by hyperventilation, which leads to excessive excretion of carbon dioxide in the body, disrupting the acid-base balance and causing a series of uncomfortable symptoms.

[0003] In the field of traditional respiratory mask technology, relatively basic methods are often used for flow regulation. It is common to install a simple manual valve in the air inlet line. Medical staff or patients adjust the gas flow by rotating the valve to change the cross-sectional area of the gas channel. When in use, medical staff will first assess the patient's approximate oxygen inhalation needs and manually rotate the valve to the corresponding opening based on experience. For example, for ordinary mild patients, the valve is rotated to a certain middle position. It is believed that the gas flow at this opening can meet the patient's basic breathing needs; if the patient's condition is slightly more serious, the valve opening may be adjusted to a larger degree.

[0004] During use, existing technologies have limited adjustment accuracy, making it difficult to accurately match the widely varying oxygen inhalation frequencies and volumes of different patients. Different patients have very different respiratory physiological characteristics. Some have a fast respiratory rate but a small inhaled volume each time, while others have the opposite. Traditional manual valves struggle to account for these complex situations. On the other hand, they cannot achieve dynamic adjustment. Once the valve opening is set, if the patient's respiratory state changes, such as a sudden increase in respiratory rate due to fluctuations in the condition, the flow rate cannot automatically adjust accordingly. Therefore, a mask for alleviating respiratory alkalosis is proposed to address the above problems. Summary of the Invention

When disassembling, the reverse operation is performed to separate the plug block from the positioning block 1903. Both plug blocks are matched with the slot 1902.

[0027] Working principle: The breathing mask is put on by the strap 5. By binding the strap 5, the breathing mask body 1 can fit the patient's face tightly, forming a relatively sealed breathing space to prevent gas leakage and ensure that the patient can breathe the gas required for treatment normally. Then connect the trachea 3 to the ventilator. Connect the trachea 3 to the ventilator to establish a gas delivery channel from the ventilator to the breathing mask body 1, so that the gas generated by the ventilator that meets the treatment requirements can smoothly enter the breathing mask for the patient to use. Push the sleeve 15, and the piston 17 inside the sleeve 15 moves on the inside of the extension tube 11 to push the sleeve 1 5 moves the piston 17 to preliminarily adjust the air flow from the trachea 3 to the extension tube 11, providing a roughly suitable air intake for the patient. The piston 17 moves inside the extension tube 11, and the block 1603 slides in the slide groove 706. The inclined surface of the block 1603 is squeezed by the snap ring 1803, which in turn drives the block 1603 to slide in the slide groove 706, so that the blocks 1603 approach each other and squeeze the spring A1602. In this process, the interaction between the block 1603 and the snap ring 1803 realizes the position locking of the piston 17 during its movement, ensuring that the piston 17 is adjusted The position after the piston 17 is stable and the adjusted air flow is maintained, the slider 1605 moves with the block 1603. Since the piston 17 is conical and matches the special conical shape of the movable groove 1801, the depth of the piston 17 inserted into the inner side of the extension tube 11 is adjusted, thereby adjusting the air flow from the trachea 3 to the extension tube 11. By utilizing the conical design of the piston 17 and the movable groove 1801, the depth of the piston 17 inserted into the extension tube 11 is changed, and the air flow is accurately adjusted to better meet the different breathing needs of the patient. When the patient breathes, the piston 17 cooperates with the intake pipe 3, the fixed pipe 8, the sleeve 15, and the extension tube 11 to adjust the air flow from the trachea 3 to the extension tube 11. 11. The air enters the inner side of the breathing mask body 1 at the interface 2 and is filtered by the filter screen 1901. The filter screen 1901 filters the oxygen entering the breathing mask body 1 to remove impurities, providing the patient with clean breathing gas and ensuring the patient's breathing safety and health. Then, when the patient exhales, the one-way valve B10 closes and the one-way valve A9 opens, allowing the carbon dioxide exhaled by the patient to be discharged from the air outlet 4. The coordinated work of the one-way valve A9 and the one-way valve B10 ensures the unidirectional flow of gas in the breathing mask. When the patient inhales, the one-way valve A9 opens and fresh air enters.During exhalation, the one-way valve B10 is closed and the one-way valve A9 is opened, and the exhaled carbon dioxide is discharged smoothly, maintaining the stability of the gas environment in the breathing mask. The monitoring sensor 6 is used to monitor the oxygen breathing volume. The monitoring sensor 6 is used to transmit a signal to the telescopic element 1802, so that the telescopic end of the telescopic element 1802 drives the clamping ring 1803 to move inside the extension tube 11, so that the clamping ring 1803 pushes the piston 17 inside the sleeve 15, thereby making a secondary adjustment to the piston 17 inside the sleeve 15, which can be adjusted according to the patient's oxygen inhalation frequency. The air intake flow monitoring sensor 6 monitors the oxygen breathing volume in real time and transmits the signal to the telescopic element 1802 to achieve secondary precise adjustment of the position of the piston 17, so that the breathing mask can dynamically adjust the air intake flow according to the patient's actual breathing situation, thereby improving the treatment effect and patient comfort. When the flow of the air outlet 4 needs to be adjusted, it is only necessary to rotate the turntable 701 so that the turntable 701 rotates on the end surface of the fixed plate 705, and the turntable 701 drives the limit rod 704 to slide on the inner wall of the arc-shaped sliding hole 702, thereby driving the limit rod 704 to slide on the inner wall of the arc-shaped sliding hole 702. The upper opening and closing plate 4 slides in the slide groove 706, and the two opening and closing plates move closer to or farther away from each other, thereby adjusting the size of the air outlet 4. By rotating the turntable 701, the limit rod 704 and the arc-shaped sliding hole 702 cooperate to drive the opening and closing plate to slide, thereby achieving precise adjustment of the size of the air outlet 4 to meet the different flow requirements of the patient during exhalation; when the trachea 3 needs to be removed, the pressure plates on both sides of the sleeve 15 are squeezed, so that the pressure plates drive the movable rod 1604 to move on both sides of the sleeve 15, and the movable rod 1604 squeezes the slider 1605 in the slide groove 706. Sliding inward, the slider 1605 drives the block 1603 into the chute 706. At this point, the block 1603 separates from the retaining ring 1803, thereby releasing the restraint between the piston 17 and the inner side of the sleeve 15. The inner side of the sleeve 15 can then be removed from the outer wall of the extension tube 11, allowing the air pipe 3 to be disassembled. By squeezing the pressure plate, the unlocking assembly 16 operates, separating the block 1603 from the retaining ring 1803. This quickly and easily releases the restraint between the piston 17 and the inner side of the sleeve 15, facilitating the removal and maintenance of the air pipe 3 and improving the maintainability of the equipment.
