[0002] Emergency respirators are widely used in medical emergency work. They are a type of equipment used in emergency situations. They are suitable for cardiopulmonary resuscitation and artificial respiration emergency situations, especially for situations of suffocation, breathing difficulties, or the need for increased oxygen supply. They are easy to use, less painful, less complicated, easy to carry, and can be used for immediate ventilation with or without an oxygen source. When the emergency respirator is in use, a mask is installed at the air outlet of the respirator. When the mask is worn, it is generally fixed to the patient's head with a strap to make the respirator fit tightly against the patient's mouth and nose to prevent gas leakage. Currently, traditional emergency breathing devices have problems such as difficulty in accurately adjusting and controlling ventilation volume and respiratory rate when used with patients of different age groups, easy fatigue when manually operated, and large parameter fluctuations, making it difficult to fully meet the complex needs of clinical emergency treatment.

[0031] Working Principle: The emergency respirator 1 consists of a face mask, a breathing bag, an oxygen connection port, a one-way valve, a pressure safety valve, an air storage bag, and a pressure gauge. During use, the breathing bag of the emergency respirator 1 can be connected to the face mask via a connecting pipe. This design does not show all the components of the emergency respirator 1. The emergency respirator 1 is a relatively common medical device. Mask: used to cover the patient's mouth and nose, forming a sealed space so that gas can be effectively delivered to the patient's respiratory tract. Masks usually come in different sizes to accommodate patients of different ages and face sizes. The material is soft and has good sealing to ensure that there is no air leakage during ventilation; The breathing bag is the core component of the emergency respirator 1. It is usually made of soft and elastic material. By squeezing the breathing bag, the gas inside the bag can be delivered to the patient's lungs. When the breathing bag is released, it will automatically return to its original shape and inhale fresh air from the outside for the next squeeze ventilation. Oxygen connection port: used to connect to the oxygen source. The oxygen flow rate can be adjusted according to the patient's needs so that the gas delivered to the patient contains sufficient oxygen to improve the patient's blood oxygen saturation; One-way valve: includes an inlet one-way valve and an exhalation one-way valve. The inlet one-way valve ensures that gas can only flow from the breathing bag to the patient, preventing the patient's exhaled gas from flowing back into the breathing bag; the exhalation one-way valve opens when the patient exhales, allowing the patient's exhaled gas to be discharged to the outside world, while preventing outside air from entering the breathing circuit when the patient exhales; Pressure safety valve: When the pressure in the breathing circuit is too high, the pressure safety valve will automatically open and release excess gas to prevent damage to the patient's lungs due to excessive pressure; Air storage bag: connected between the oxygen source and the breathing bag. When the oxygen flow is large, the air storage bag can store a certain amount of oxygen to ensure that sufficient high-concentration oxygen can be provided when the breathing bag is squeezed; Pressure gauge: used to display the pressure in the breathing circuit. Medical staff can judge whether the ventilation pressure is appropriate based on the reading of the pressure gauge to avoid adverse effects on patients caused by excessively high or low pressure; When the device is in use, it is connected to an external power source and the breathing bag of the emergency respirator 1 is inserted between the two limit frames 311. During this process, the breathing bag of the emergency respirator 1 can be deformed, and the emergency respirator 1 can be easily operated. Under the action of the two limit frames 311, the position of the emergency respirator 1 can be restricted. The controller starts the constant speed motor 54, and the operation of the constant speed motor 54 drives the conical roller 55 to rotate through the rotating shaft 1 56. The rotation of the conical roller 55 drives the friction wheel 59 to rotate synchronously. The rotating sleeve 511 and the insert rod 513 of the friction wheel 59 rotate synchronously, thereby driving the rotating shaft 2 58 to rotate. The rotation of the rotating shaft 2 58 drives the two push rods 57 to rotate synchronously. In the process of the rotation of the two push rods 57, when the push rods 57 rotate to fit the bottom surface of the L-shaped lifting plate 517, the L-shaped lifting plate 517 can be lifted as the push rods 57 rotate. Lifting, the movement of the L-shaped lifting plate 517 drives the rectangular sleeve 37 to move synchronously. At this time, one end of the push rod 57 is against the bottom surface of the L-shaped lifting plate 517, so that the rectangular sleeve 37 is continuously raised. When the push rod 57 slides out from the bottom surface of the L-shaped lifting plate 517, the second cross bar 36, the rectangular sleeve 37 and other components can be quickly moved downward under the action of gravity. As the constant speed motor 54 continues to run, the second cross bar 36 and the rectangular sleeve 37 continue to perform this action, that is, the second cross bar 36 and the rectangular sleeve 37 move up and then quickly move down; The two L-shaped lifting plates 517 are attached to the surface of the mounting housing 2, thereby enabling the rectangular sleeve 37 to move longitudinally and limiting the range of movement of the rectangular sleeve 37; During the synchronous upward movement of the crossbar 2 36 and the rectangular sleeve 37 , the hollow rod 41 is in a vertical state. During the upward movement of the rectangular sleeve 37 and the crossbar 2 36 , the movement of the crossbar 2 36 drives the circular shaft 1 35 to slide inside the bending groove 34 , and drives the circular shaft 2 42 to slide inside the hollow rod 41 . Under the restriction of the shape of the bending groove 34 , during the upward movement of the circular shaft 1 35 , the pull block 33 drives the longitudinal rod 1 310 to move toward the mounting housing 2 . The movement of the longitudinal rod 1 310 drives the crossbar 1 32 to push the pressure plate 31 to move, thereby causing the pressure block 39 to squeeze the breathing bag of the emergency respirator 1 . During this process, the movement of the crossbar 1 32 drives the connecting plate 1 65 to move synchronously, thereby driving the gear bar 1 61 to move. The movement of the gear bar 1 61 drives the gear 63 meshing with it to rotate, thereby driving the gear bar 2 64 to move. The movement of the gear bar 2 64 drives the other crossbar 1 32 to move through the connecting plate 2 66, thereby achieving the effect of moving the two crossbars 1 32. When the crossbar 2 36 and the rectangular sleeve 37 move upward, the two pressing blocks 39 can simultaneously squeeze the breathing bag of the emergency respirator 1, and the two pressing blocks 39 are symmetrically arranged inside the mounting shell 2, thereby ensuring the squeezing effect on the breathing bag of the emergency respirator 1. Squeezing the breathing bag of the emergency respirator 1 can deliver the gas in the bag to the patient's lungs. When the push rod 57 slides out from the bottom surface of the L-shaped lifting plate 517, causing the cross bar 2 36 and the rectangular sleeve 37 to move downward rapidly, the circular shaft 1 35 slides inside the bending groove 34 under the shape restriction of the bending groove 34, causing the longitudinal rod 1 310 to move away from the mounting shell 2, thereby causing the two pressing blocks 39 to move rapidly away from the emergency respirator 1. At this time, the breathing bag of the emergency respirator 1 is released, and it will automatically return to its original state under the restriction of its material and shape, and inhale fresh air from the outside for the next squeeze ventilation. The operation of the constant-speed motor 54 enables the two pressing blocks 39 to simulate the squeezing of the breathing bag of the emergency respirator 1 by human hands, thereby accurately controlling the compression frequency, compression depth, and compression time of the breathing bag of the emergency respirator 1. Compared with manual operation, the operation of the constant-speed motor 54 enables the two pressing blocks 39 to simulate the squeezing of the breathing bag by human hands without causing fluctuations in compression parameters due to factors such as fatigue and tension, thereby providing more stable ventilation and respiratory rate that better meet the patient's needs, ensuring that the patient receives continuous and effective respiratory support; When it is necessary to adjust the ventilation volume and respiratory rate according to the age of the patient, the ventilation volume and respiratory rate of different age groups are different due to the different age groups of the patient. For example, the ventilation volume for adults is usually 500-600 ml per breath, and the respiratory rate is usually 10-12 times per minute. The ventilation volume for children aged 3-12 years old varies according to the age and weight of the child, and is generally 10-15 ml / kg body weight per breath. For example, a child aged 5-7 years old has a ventilation volume of about 200-300 ml per breath, and a respiratory rate of 12-18 times per minute for a child aged 3-12 years old. The respiratory rate of the elderly is generally 10-12 times per minute, and the ventilation volume is about 400-500 ml per breath. When the clinical emergency breathing apparatus is used on an adult, the hollow rod 41 is in a vertical position. At this time, the ventilation volume of the breathing bag of the emergency breathing apparatus 1 is usually 500 ml, and the breathing frequency is just between 10 times; When the clinical emergency breathing device is used for children aged 3-12, it is necessary to reduce the ventilation volume each time. The operator steps on the pedal 47 and applies a downward force to move the pedal 47 downward. The movement of the pedal 47 drives the bottom plate 44 downward through the longitudinal rod 48, so that the spring 45 is stretched. When the triangular bar 412 moves a distance away from the surface of the positioning plate 411, the hollow rod 41 is operated to rotate the hollow rod 41 on the surface of the circular shaft 42 at a certain angle clockwise. The hollow rod 41 rotates on the surface of the circular shaft 42 at a certain angle. During the movement, the circular shaft 346 can slide inside the through groove 410. When the circular shaft 346 moves to a suitable position, the force applied to the pedal 47 is released. Under the action of the elastic potential energy of the spring 45, the triangular bar 412 can fit the surface of the positioning plate 411, thereby fixing the position of the positioning plate 411, that is, fixing the hollow rod 41 after the adjusted position. At this time, when the rectangular sleeve 37 moves upward, the circular shaft 242 slides inside the hollow rod 41, thereby causing the cross bar 243 to move toward the direction close to the pull block 33, and because the cross bar 243 is in the direction close to the pull block 33, the cross bar 243 is in the direction close to the pull block 33. During the vertical upward movement, the ventilation volume of the breathing bag of the emergency respirator 1 is squeezed to 500 ml. During the upward movement of the crossbar 2 36 and the movement in the direction close to the pull block 33, the displacement of the pull block 33 can be reduced, thereby reducing the ventilation volume of the breathing bag of the emergency respirator 1. When the hollow rod 41 rotates clockwise, the square shell 515 and the crossbar 3 518 are pulled synchronously by the circular shaft 3 46, thereby pulling the friction wheel 59 to slide on the surface of the friction wheel 59. At this time, the friction wheel 59 moves toward the direction with a larger diameter of the tapered roller 55, and the friction wheel 59 is pulled to slide on the surface of the friction wheel 59. The constant speed motor 54 drives the conical roller 55 to rotate at a constant speed, thereby increasing the number of rotations of the friction wheel 59 per minute. When the friction wheel 59 rotates one circle, the breathing bag of the emergency respirator 1 can be squeezed once, thereby synchronously increasing the respiratory rate. When the respiratory rate needs to be fine-tuned according to the use of the device, the screw 519 is rotated to make the cross bar 3 518 slide inside the square sleeve housing 515, and then the sleeve 511 drives the friction wheel 59 to slide on the surface of the second rotating shaft 58, thereby achieving the effect of independently adjusting the respiratory rate by rotating the screw 519. When the clinical emergency breathing device is used on elderly people, since the respiratory rate of the elderly is generally 10-12 times per minute, the ventilation volume per time is about 400-500 ml, which is between that of children and adults, but the respiratory rate is similar to that of adults. After the hollow rod 41 is rotated to an appropriate position, the respiratory rate increases synchronously when the ventilation volume per time is reduced. At this time, it is necessary to manually rotate the screw 519 to adjust the respiratory rate, so that the overall length of the square shell 515 and the cross bar 3 518 is increased, which can make the friction wheel 59 slide outside the second rotating shaft 58, that is, the friction wheel 59 moves toward the end with a smaller diameter of the tapered roller 55. At this time, the respiratory rate continues to decrease with the movement of the friction wheel 59 until it is adjusted to a respiratory rate suitable for the elderly. The tapered roller 55 is placed in an inclined manner, and the upper part of the tapered roller 55 is located in a horizontal plane. During the sliding of the cylindrical sleeve 511 on the surface of the second rotating shaft 58, the friction wheel 59 always contacts the surface of the tapered roller 55. The diameter of the end of the tapered roller 55 close to the hollow rod 41 is larger, thereby achieving the effect of adjusting the vertical movement frequency of the rectangular sleeve 37 during the movement of the friction wheel 59. The upper surface of the U-shaped plate 49 is inlaid with scale lines at equal intervals, and the corresponding ventilation volume is marked on the scale lines at different positions, which is convenient for quickly adjusting the ventilation volume. At the same time, the surface of the rotating shaft 58 is also inlaid with scale lines at equal intervals, and the corresponding respiratory frequency is marked at the corresponding scale line position, which is convenient for quickly adjusting the respiratory frequency.
