Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of simple respirator structure, and in particular to a simple respirator that is convenient for single-person operation. Background Technology
[0002] A simple respirator is a portable, manually operated respiratory assist device that provides necessary ventilation support for patients with respiratory failure or respiratory arrest. Also known as an artificial respirator, pressurized oxygen bag, or resuscitation ball, it is a simple tool for artificial ventilation. Its working principle is that oxygen enters the spherical air bag and oxygen reservoir. By manually pressing the air bag with your fingers to open the front valve, oxygen is forced into the mask or endotracheal tube that is placed close to the patient's mouth and nose to achieve the purpose of artificial ventilation.
[0003] A simple respirator typically consists of an inlet valve, a compressor unit, and a patient valve, and is usually equipped with accessories such as a reservoir bag and a breathing mask. Currently, simple respirators require two people to operate. One person needs to support the patient's chin with both hands and push it forward to tilt the head back while simultaneously lifting the chin upwards to open the airway. The other person needs to press the mask and the respirator bag to assist the patient in breathing the oxygen from the reservoir bag. This method has several problems: first, it cannot be operated by a single person and requires two people, making the operation less labor-saving and convenient; second, the patient's chin needs to be supported continuously. Utility Model Content

A strap is fitted onto the outside of the mask. A guide rail strip is clamped onto the lower surface of the strap. A neck support plate is fixedly installed on the lower surface of the guide rail strip. An air inlet valve is fixedly installed at the rear end of the airbag. An air storage valve is fixedly installed on the rear surface of the air inlet valve. An oxygen storage bag is fixedly installed at the rear end of the air storage valve. A connecting tube is fixedly connected between the air inlet valve and the oxygen storage bag.
[0007] Preferably, the strap includes an elastic band, a hook strip, and a handle.
[0008] Preferably, the outer side of the mask is fitted with an elastic band, and the hook strip is fixedly installed at both ends of the elastic band.
[0009] Preferably, the handle is fixedly installed on the lower surface of the hook strip, and the hook strip is fastened to the outside of the guide rail edge strip.

[0011] Preferably, the base plate frame is fixedly installed on the lower surface of the guide rail edge strip, and the guide rail edge strip is located at the edge of the upper surface of the base plate frame.
[0012] Preferably, the skateboard is located inside the base frame, the four-sided knob is located in the through hole on the front surface of the skateboard, the screw is fixedly installed at the front end of the four-sided knob, the bending plate is fixedly installed on the front surface of the skateboard, the first sponge pad is fixedly installed on the upper surface of the base frame, the first rubber pad is fixedly installed on the upper surface of the first sponge pad, the second sponge pad is fixedly installed on the upper surface of the skateboard, the second rubber pad is fixedly installed on the upper surface of the second sponge pad, the front end of the screw is inserted into the threaded through hole of the base frame, and the front end of the bending plate is fixedly connected to the base frame.
[0013] This utility model, by setting straps and guide rails, can fasten the mask to the face without the rescuer pressing the mask, which can prevent the patient's head from shaking from side to side. The operation process is convenient and simple. In addition, the straps can slide on the guide rails and can be adjusted according to the position of the mask.
[0014] The neck support plate can be adjusted to change the height of the patient's neck, thereby lifting the chin and opening the airway. This eliminates the need for the rescuer to support the patient's chin with both hands to open the airway, making it much easier. Attached Figure Description

The strap 5 can slide on the guide rail 6, allowing adjustment based on the position of the mask 4. The neck support plate 7 can adjust the height of the patient's neck, thereby lifting the chin and opening the airway. This eliminates the need for the rescuer to support the patient's chin with both hands to open the airway, making it more labor-saving. In use, the mask 4 is strapped to the patient's face using the strap 5 and guide rail 6. The neck support plate 7 supports the neck, lifts the chin, and opens the airway. The rescuer presses the air bag 1 to bring oxygen from the oxygen storage bag 10 into the mask 4, assisting the patient in inhaling oxygen.
[0022] In this embodiment, the strap 5 includes an elastic band 501, a hook strip 502, and a handle 503.
[0023] In this embodiment, an elastic band 501 is fitted on the outer side of the mask 4, and hook strips 502 are fixedly installed at both ends of the elastic band 501.
[0024] In this embodiment, the handle 503 is fixedly installed on the lower surface of the hook strip 502. The hook strip 502 is fastened to the outside of the guide rail edge strip 6. When the mask 4 is fastened to the patient's mouth and nose, the handle 503 is held and the hook strip 502 is pulled down to remove the hook strip 502 from the guide rail edge strip 6. After the mask 4 is covered on the patient's mouth and nose, the handle 503 is held and the hook strip 502 is pulled down to allow the hook strip 502 to be reattached to the guide rail edge strip 6. The hook strip 502 can slide on the guide rail edge strip 6.
[0025] In this embodiment, the neck support plate 7 includes a base frame 701, a sliding plate 702, a four-sided knob 703, a screw 704, a bending plate 705, a first sponge pad 706, a first rubber pad 707, a second sponge pad 708, and a second rubber pad 709.

When the airway is opened, the patient... The head rests on the slide plate 702 with the second sponge pad 708 and the second rubber pad 709 as a support. The patient's back is pressed against the front end of the base frame 701 with the first sponge pad 706 and the first rubber pad 707 as a support. The first sponge pad 706 and the second sponge pad 708 provide cushioning and shock absorption, while the first rubber pad 707 and the second rubber pad 709 provide anti-slip properties. When adjusting the neck height, turn the four-sided knob 703 to rotate the screw 704, which then rotates into the threaded through hole of the base frame 701. The slide plate 702 slides within the base frame 701, and the angle of the bending plate 705 decreases.
