Specifically, the extrusion device comprises a pull rope 200 and an automatic wire collecting box 2 for rewinding the pull rope 200, wherein two ends of the pull rope 200 respectively extend out of two side walls of the automatic wire collecting box 2 and are connected with pillow corners of the oxygen pillow body 1. As shown in fig. 3-5, the automatic wire winding box 2 in this embodiment is provided with a rollback component 4 and a locking component 5, specifically, the automatic wire winding box 2 includes a box body 21 and a box cover 22, a wire winding cavity is provided in the box body 21, a fixed shaft 23 is provided in the center of the wire winding cavity, and a wire opening 24 for entering and exiting a pull rope 200 is provided on the side wall of the box body 21; as shown in fig. 3, the rewinding assembly 4 comprises a winding disc 41 and a spring 42, one end of the spring 42, which is positioned at the disc center, is fixedly connected with the fixed shaft 23, the other end of the spring is connected with the inner wall of the winding disc 41, and the winding disc 41 is rotatably arranged in a winding cavity; the pull cord 200 is wound around the outer circumference of the take-up reel 41, and both free ends of the pull cord 200 are reversely wound and extended from the wire opening 24. When the pull rope 200 is pulled out, the take-up reel 41 rotates around the fixed shaft 23, one end of the spring 42 rotates along with the take-up reel and generates elastic deformation, and the locking assembly 5 plays a limiting role on the take-up reel 41 at the moment, so that the take-up reel 41 is prevented from reversing under the elastic rewinding effect of the spring 42.

As shown in fig. 4-5, a mounting groove 211 communicated with the wire collecting cavity is formed in the side wall of the box body 21, a threaded rod 6 and a rotating rod 7 rotationally connected with the threaded rod 6 are arranged in the mounting groove 211, the threaded rod 6 is in threaded connection with the mounting groove 211, the rotating rod 7 is in sliding connection with the mounting groove 211, and a step surface 70 is further arranged on the rotating rod 7; the mounting groove 211 is provided with the spacing groove 212 on the one end inner wall that is close to the admission chamber, is provided with the gag lever post 72 on the corresponding lateral wall of dwang 7, and the gag lever post 72 slidingly sets up in the spacing groove 212. As shown in fig. 4, the locking assembly 5 comprises a ratchet 51, a pawl 52 and a reed 53 for resetting the pawl 52, wherein the ratchet 51 is fixed at the bottom of the take-up reel 41, the reed 53 is fixed on a step of the rotating rod 7 through a screw, the pawl 52 is rotatably arranged on a step surface 70 and is contacted with the reed 53, and a limit part 71 for limiting unidirectional movement of the pawl 52 is further arranged on the step surface 70; specifically, the stopper 71 and the spring 53 are located on both sides of the pawl 52, and when the ratchet 51 rotates to push the pawl 52 to move away from the tooth surface, the spring 53 is pressed and pushes the pawl 52 to return, thereby ensuring that the pawl 52 is engaged with the ratchet 51.

The working principle of the automatic wire-rewinding box 2 is as follows: when the two ends of the pull rope 200 are pulled outwards, the take-up reel 41 is driven to rotate, the take-up reel 41 rotates to drive the ratchet wheel 51 to rotate, at the moment, the pawl 52 meshed with the ratchet wheel 51 slides on the teeth of the ratchet wheel 51, when the pull rope 200 is pulled out for a required length, the force is stopped, at the moment, the spring 42 can retract under the action of elastic deformation, the take-up reel 41 rotates in the opposite direction, but due to the limit action of the pawl 52 on the ratchet wheel 51, the ratchet wheel 51 cannot rotate reversely, the take-up reel 41 stops rotating, the spring 42 stops retracting, and the pull wire cannot rewind. When the extended pulling rope 200 needs to be retracted, the threaded rod 6 is rotated to enable the rotating rod 7 to slide outwards in the limiting groove 212, so that the pawl 52 clamping the ratchet wheel 51 is separated from the teeth of the ratchet wheel 51, the ratchet wheel 51 is out of limit, and the winding disc 41 reversely rotates to wind the released pulling rope 200 back to the periphery of the winding disc under the winding acting force of the spring 42.

In the embodiment, the side wall of the oxygen pillow body 1 is also provided with a protective layer 3, and the long edges of the two sides of the protective layer 3 are adhered or sewn along the edge of the oxygen pillow body 1, so that a containing cavity is formed in the protective layer 3; the automatic wire collecting box 2 is positioned in the middle of the accommodating cavity, pull ropes 200 on two sides of the automatic wire collecting box 2 are also positioned in the accommodating cavity, and the pull ropes 200 are respectively fixed with the pillow corners of the oxygen pillow body 1; the protective layer 3 is provided with an opening, the threaded rod 6 extends out through the opening, so that a medical staff can conveniently rotate the threaded rod 6 to enable the pawl 52 to be separated from the ratchet wheel 51, and accordingly automatic winding of the pull rope 200 is achieved. Specifically, the two pillow corners of the oxygen pillow body 1 are connected with connecting buckles, and the connecting buckles can be made of metal buckles or cloth; the two ends of the pull rope 200 are connected with connectors which are matched with the connectors, and the connectors are preferably climbing buckles (not shown in the figure) in the embodiment.

The specific implementation process is as follows: when the nasal suction tube at the end part of the air duct 11 is inserted into the nasal cavity of a patient firstly, the adjusting clamp 12 is opened, oxygen in the oxygen pillow body 1 flows out, the air pressure in the oxygen pillow body is reduced along with the consumption of the oxygen, the oxygen pillow body 1 is shrunken, at the moment, a medical staff rotates the threaded rod 6, the pull rope 200 starts to shrink inwards towards the automatic wire collecting box 2, the pillow angle of the oxygen pillow body 1 connected with the pull rope is pulled, the pillow angle of the oxygen pillow body 1 is wound towards the center along with the shrinkage, so that the oxygen in the oxygen pillow body is extruded, and the oxygen is stably output from the air duct 11.

Example two

The difference between the present embodiment and the first embodiment is that, as shown in fig. 6, a monitoring device for detecting oxygen flow is provided at one end of the air duct 11 near the oxygen pillow body; specifically, the monitoring device comprises a flowmeter 14, an alarm 15 and a controller 13, wherein the flowmeter 14 is arranged on the air duct 11, the flowmeter 14 is electrically connected with the controller 13, and the alarm 15 is also electrically connected with the controller 13; in this embodiment, the controller 13 with the alarm 15 is preferably selected, and the alarm 15 includes an alarm lamp or a buzzer. When the oxygen output in the oxygen pillow body 1 is lower than a certain value, the flowmeter 14 transmits a signal to the controller 13, the controller 13 controls the alarm 15 to alarm, medical staff can be reminded that the oxygen output is insufficient, and at the moment, the medical staff pushes the rocker 53 on the automatic wire collecting box 2 to enable the pull rope 200 to shrink to squeeze the oxygen pillow body 1, so that the oxygen in the oxygen pillow body 1 is ensured to be continuously output.
