Portable emergency respirator for emergency nursing

Abstract

The invention relates to the technical field of respirators, in particular to a portable emergency respirator for emergency nursing. The portable emergency respirator comprises a mask, an air bag andan air supply pipe; a rubber ring is arranged on the end face, making contact with the skin, of the mask in the circumferential direction; the rubber ring is hollow; and a notch is formed in the innerside of the contact position of the rubber ring and the mask. Due to the fact that exhaled air of the human body contains moisture, water vapor gradually condensed in the worn mask can be doped intothe nasal cavity in the use process of the respirator, normal respiration of the human body is disturbed, and finally the effective effect of the respirator is destroyed. Therefore, through the hollowinterior of the rubber ring on the mask, water vapor in the exhaled air when the mask is used is condensed and collected and then discharged into a water collecting bag through a guide pipe, the relatively dry environment in the using process of the mask is kept, interference of the water vapor in the mask with the inspiration process is avoided, and then the using effect of the portable emergency respirator for emergency nursing is improved.

Description

technical field [0001] The invention relates to the technical field of respirators, in particular to a portable emergency respirator for emergency care. Background technique [0002] The respirator is a self-contained open-air respirator, which is widely used in various industries. Among them, the medical portable respirator has a face mask with good airtightness, and the air supply device is equipped with small size, light weight, stable performance, and is easy to cooperate with The use of various situations in medical treatment; for the introduction of portable respirators, please refer to: Lu Renyan, Application of Portable Respirators in Hospital Examination of Mechanically Ventilated Patients [J], Medical Information, 2011(No.1).296-297 . [0003] At present, after the portable respirator is worn, the water vapor generated during breathing condenses in the mask, and finally forms water droplets to accumulate, which will affect the normal breathing rhythm of the wearer...

AI Technical Summary

Problems solved by technology

[0003] At present, after the portable respirator is worn, the water vapor generated during breathing condenses in the mask, and finally forms water droplets to accumulate, which will affect the normal breathing rhythm of the wearer. At the same time, the condensed water droplets are inhaled into the nasal cavity so that the wearer can breathe choking, resulting in unpredictable consequences, the water vapor treatment in the respirator mask has become the main problem to be solved

[0004] There are also some technical solutions about portable emergency respirators for emergency care in the prior art. For example, a Chinese patent with application number 2018205717194 discloses a portable emergency respirator for emergency care, including a breathing sphere and a breathing mask. The top of the sphere is connected with an air outlet pipe, and a support rod is fixedly connected between the two sides of the inner wall of the air outlet pipe. The middle of the support rod is fixedly connected with a rotating shaft. One end of the arc-shaped rod is fixedly connected with a sports clip, the bottom of the breathing mask is connected with an intake pipe, the intake pipe and the outlet pipe are connected, and both sides of the inner wall of the intake pipe are provided with clamping grooves, and the sports clip is snapped into the clip. Tight groove; the portable emergency respirator for emergency care in this technical solution solves the problem that the emergency respirator is not easy to carry and install after disassembly during emergency care, effectively improves the portability of the emergency respirator, and avoids the The patient's treatment delay caused by the inability to quickly install after disassembly greatly improves the effectiveness of the patient's emergency treatment; however, the respirator in this technical solution fails to solve the water vapor generated during the breathing process, and eventually the water vapor formed by condensation Beads can seriously interfere with respirator performance
