Abstract

The utility model discloses a portable mouth-noise artificial respirator which comprises an outer cylinder and an inner cylinder, wherein, the inner peripheral surface of the outer cylinder is provided with external thread. The outer peripheral surface of the inner cylinder is provided with internal thread matched with the external thread of the outer cylinder. Furthermore the inner cylinder is sleeved in the outer cylinder in a sealed mode. The lower end of the inner cylinder is provided with a hollow wedge-shaped air ventilation nozzle. The periphery of the lower part of outer cylinder is provided with an anti-air-leakage mouth ring. The middle part of the outer cylinder is provided with two air ventilation flexible pipes. The end of each flexible pipe is provided with a hollow nasal stopper. The wall of the inner cylinder is provided with two ventilation holes matched with two air ventilation flexible pipes. The rotation of the inner cylinder can cause the ventilation holes to communicate with the air ventilation flexible pipes of the outer cylinder. The portable mouth-noise artificial respirator has the following advantages: simple structure, small volume, suitability for being carried about, and high convenience in field first aid before taking into the hospital; suitability for mouth-to-mouth and mouth-to-nose use; rotatable designed inner cylinder, convenient conversion between mouth-to-mouth and mouth-to-nose, simple and reasonable structure; prevented unsanitary direct contact between the rescuing personnel and a patient; convenient disinfection, and suitability for being recycled.

Description

Portable mouth and nose artificial ventilator

Technical field

This utility model relates to artificial ventilator, is specifically related to a kind ofly can be used for mouth to mouth, mouthful to the artificial ventilator of nose dual-purpose portable mouth and nose.

Background technology

When traffic accident, electric shock, drowned or fortuitous event such as hang oneself and take place, or heart respiratory arrest or cardiac arrest can occur when happening suddenly with the anxious critical illness of non-heart.At this moment, the salvage at scene person First aid such as must practice artificial respiration immediately on the spot to save patient's life.Implement artificial respiration's First aid two kinds of methods are arranged: the one, direct life-kiss, the 2nd, in the time can't being opened, need direct mouthful to the nose artificial respiration by the person's of rescuing gnathospasma.But rescuer and patient were both unhygienic directly mouth to mouth or mouthful nose contact, and cross infection easily again, and directly practicing artificial respiration is mouth to mouth also leaked gas, efficient is low easily.This worry and poor efficiency to cross infection can influence effective enforcement of artificial respiration's First aid.

The utility model content

The purpose of this utility model is for a kind of portable mouth and nose artificial ventilator is provided, when the fortuitous event generation, when respiratory arrest appears in the someone, both can be immediately whereby device implement mouth to mouth or mouthful first aid the nose artificial respiration, can avoid again between rescuer and the rescued directly mouth to mouth or mouthful the unhygienic of nose contacted.

The technical solution of the utility model is as follows: design a kind of portable mouth and nose artificial ventilator, comprise urceolus and inner core, wherein, described urceolus inner peripheral surface is provided with external screw thread, the inner core outer peripheral face also is provided with the female thread that matches with the urceolus external screw thread, and the inner core sealing is screwed in urceolus inside, and the lower end of described inner core is equipped with hollow wedge ventilation mouth; The periphery, bottom of described urceolus is equipped with leakproof QI KOU circle; The middle part of described urceolus is provided with two steam hoses, and the end of flexible pipe is provided with the nasal obstruction of hollow; Have two passages that match with two steam hoses on the described inner core barrel, the rotation inner core can make the steam hose conducting of this passage and urceolus.

According to portable mouth and nose artificial ventilator provided by the utility model, it is characterized in that described passage is set to two funnel-like than macropore, the interval between the interval between the adjacent passage and the two steam hose roots equates, the rotation inner core arrives suitable angle, but with regard to the conducting steam hose.

The beneficial effects of the utility model are as follows: 1, easy, volume is little, can carry, first aid on the spot before being convenient to be in hospital; 2, can be mouth to mouth, mouthful dual-purpose to nose; 3, inner core is designed to rotaryly, makes mouth to mouth, mouthful convenient, simple and reasonable to the nose conversion; 4, the rescue personnel has avoided unhygienic with the patient and has directly contacted; 5, cleaning-sterilizing is convenient, can use repeatedly.

Wherein, 1, urceolus, 2, inner core, 3, female thread, 4, hollow wedge ventilation mouth, 5, leakproof QI KOU circle, 6, steam hose, 7, nasal obstruction, 8, passage.

The specific embodiment

Below in conjunction with accompanying drawing this utility model is elaborated.

As shown in Figure 1, a kind of portable mouth and nose artificial ventilator, comprise urceolus 1 and inner core 2, wherein, urceolus 1 inner peripheral surface is provided with external screw thread, inner core 2 outer peripheral faces also are provided with the female thread 3 that matches with the urceolus external screw thread, and inner core 2 sealing is screwed in urceolus 1 inside, and the lower end of described inner core 2 is equipped with hollow wedge ventilation mouth 4; The periphery, bottom of described urceolus 1 is equipped with leakproof QI KOU circle 5; The middle part of described urceolus 1 is provided with two steam hoses 6, and the end of steam hose 6 is provided with the nasal obstruction 7 of hollow; Have two passages 8 that match with two steam hoses 6 on described inner core 2 barrels, rotation inner core, steam hose 6 conductings of this passage 8 and urceolus 1.When carrying out life-kiss, inner core 2 clockwise directions are rotated, make hollow wedge ventilation mouth 4 all lean out urceolus 1 (when hollow wedge shape ventilation mouth 4 leans out urceolus 1, passage 8 and steam hose 6 dislocation, not conducting between passage 8 and the steam hose 6), the patient is lain on the back, the head layback, press leakproof QI KOU circle 5 between patient's gum and lip gently this moment, with hollow wedge ventilate mouth 4 insert between patient's teeth (when patient's mouth slight when closed, hollow wedge can be ventilated mouth 4 as crowbar, pry open the little mouth that closes of patient gently), set up artificial respiration's passage; To have a stuffy nose simultaneously and 7 insert two nostrils (when preventing to blow, gas leaks from nasal cavity); This moment, rescuer was breathed requirement per capita with 2 air blowings of mouth aligning inner core, realized artificial respiration's operation.

As shown in Figure 2, when patient's gnathospasma, in the time of can't carrying out life-kiss or lip damage need carry out mouth to the nose artificial respiration time, then with inner core 2 counter rotations, make hollow wedge ventilation mouth 4 all shrink urceolus 1 (this design is for fear of damage patient lip) when hollow wedge shape ventilation mouth 4 least significant ends shrink into urceolus 1, passage 8 and steam hose 6 para-positions, conducting between passage 8 and the steam hose 6, patient is lain on the back, the head layback, cover on patient mouth (during anti-blow leak) with leakproof QI KOU circle 5 this moment, to have a stuffy nose simultaneously and 7 insert two nostrils, set up artificial respiration's passage; This moment, rescue personnel's oral area pressed off 2 mouthfuls of inwardly air blowings of inner core, carried out mouth to the nose artificial respiration.
