Description

Technical Field

[0001] The present invention relates to the technical field of respirators, and particularly to a multifunctional emergency respirator. Background Art

[0002] An emergency respirator mainly consists of a face mask, an airbag, an oxygen storage bag, and an oxygen conduit. When in use, the airbag is squeezed, and the gas is sent into the lungs of the first aider through the face mask. The airbag is squeezed regularly to provide sufficient breathing time for the patient to help the patient breathe.

[0003] For example, the Chinese patent with the publication number "CN220002638U" discloses "an emergency respirator", whose main structure includes a face mask, a support assembly, and a fastening assembly. A fixedly connected tray is installed below the face mask, and two fixedly connected telescopic rods are installed at the bottom of the tray. The bottom ends of the telescopic rods are all installed with rotatably connected brackets. When using this emergency respirator, first place the tray under the patient's chin, then attach the face mask to the patient's face, then unscrew the knob, extend the telescopic rods, and rotate the brackets to adjust the angles of the brackets so that the brackets abut against the patient's shoulders. Then tighten the knob. At this time, through the cooperation of the tray, the telescopic rods, and the brackets, the patient's chin and head can be supported, avoiding the problem that it is inconvenient for medical staff to hold the patient's chin with one hand while covering the patient's face with the face mask and then having to free a hand to squeeze the airbag during single-person operation.

[0004] However, the above-mentioned emergency respirator requires manual squeezing of the airbag. On the one hand, the accuracy of controlling the frequency and squeezing depth is relatively low, and on the other hand, cyclic squeezing will cause hand fatigue of medical staff. Summary of the Invention

[0024] In order to convert the axial rotational motion into an axial reciprocating cyclic motion, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4, it is necessary to set up a reciprocating cycle mechanism 5, which internally has a longitudinally hollow outer shell 51 in a hollow state, a rotating wheel 59 located inside the longitudinally hollow outer shell 51 and capable of rotating with the rotor of the driving motor 2, a reciprocating chute 511 provided on the outer circumferential surface of the rotating wheel 59, and a convex guide rail head 513 inserted into the reciprocating chute 511 and capable of generating longitudinal reciprocating motion when the reciprocating chute 511 rotates.

At this time, the rotating reciprocating chute 511 will cause the convex guide rail head 513 to perform longitudinal reciprocating motion, thereby driving the limit moving ring 512 and the longitudinal moving rod 514 to perform longitudinal reciprocating cycle motion.

[0025] Regarding the specific structure of the reciprocating cycle mechanism 5, please refer to Figure 3 and Figure 4 , including a longitudinally hollow outer shell 51. A first component mounting plate 52 fixedly connected to the bottom end of the motor fixed outer shell 1 is provided at the top end of the longitudinally hollow outer shell 51.

[0026] In order to achieve the reciprocating cycle piston-type gas unidirectional driving function, please refer to Figure 1 , Figure 2 ,Figure 5 and Figure 6 , it is necessary to set up a piston-type oxygen delivery mechanism 6, which is internally provided with an oxygen compression housing 61 fixedly installed at the bottom of the longitudinal hollow housing 51 and hollow inside, a piston plate 65 placed inside the oxygen compression housing 61 and capable of reciprocating longitudinally along the convex guide rail head 513, and performing gas compression and inhalation work on the cavity below it, and a first gas check valve 610 and a second gas check valve 611 capable of controlling the one-way flow of oxygen from the oxygen injection pipe 3 and through the oxygen discharge pipe 4. The piston plate 65 will reciprocate longitudinally along the longitudinal movable rod 514. When the piston plate 65 moves upward, the first gas check valve 610 opens and the second gas check valve 611 closes, and oxygen will be inhaled from the oxygen storage bag into the inside of the gas compression chamber 63. When the piston plate 65 moves downward, the first gas check valve 610 closes and the second gas check valve 611 opens, and oxygen is discharged from the gas compression chamber 63 and the oxygen discharge pipe 4 towards the oxygen mask. This cycle repeats, so as to supply gas to the patient.

[0027] Regarding the specific structure of the piston-type oxygen delivery mechanism 6, please refer to Figure 5 and Figure 6 , including an oxygen compression housing 61. The top of the oxygen compression housing 61 is provided with a third component mounting plate 62 integrally structured with it and fixedly installed at the bottom of the second component mounting plate 55.

The outer surface of the oxygen compression housing 61 is provided with a first docking channel 68 and a second docking channel 69 fixedly connected to the oxygen injection pipe 3 and the oxygen discharge pipe 4 respectively. The first gas check valve 610 and the second gas check valve 611 are fixedly installed inside the first docking channel 68 and the second docking channel 69 respectively. The intake direction of the first gas check valve 610 is close to the oxygen injection pipe 3, and the exhaust direction is close to the gas reserve chamber 67. The intake direction of the second gas check valve 611 is close to the gas reserve chamber 67, and the exhaust direction is close to the oxygen discharge pipe 4.

[0028] In use, the oxygen injection tube 3 is connected to the oxygen storage bag storing oxygen, and then the oxygen discharge tube 4 is connected to the oxygen mask. Start the drive motor 2, and controlling the rotation speed of the rotor can control the pressure and frequency during oxygen delivery. At this time, the rotor will drive the rotating wheel 59 to rotate. At this time, the rotating reciprocating chute 511 will cause the convex guide rail head 513 to move longitudinally back and forth, thereby driving the limit moving ring 512 and the longitudinal movable rod 514 to perform longitudinal reciprocating cyclic motion. At the same time, the piston plate 65 will perform longitudinal reciprocating motion along with the longitudinal movable rod 514. When the piston plate 65 moves upward, the first gas one-way valve 610 opens and the second gas one-way valve 611 closes, and oxygen will be inhaled from the oxygen storage bag into the interior of the gas compression chamber 63. When the piston plate 65 moves downward, the first gas one-way valve 610 closes and the second gas one-way valve 611 opens, and oxygen is discharged from the gas compression chamber 63 and the oxygen discharge tube 4 towards the oxygen mask. This cycle repeats, thereby supplying gas to the patient.
