Abstract

The utility model discloses a portable artificial respirator, which is composed of a retractable gas pump, a cartridge ventilation room, an elastic communicating pipe, a face shield, etc. Four air passages are arranged on the lateral sides of the ventilation room. A one-way valve and a bidirectional valve are arranged in the cartridge. Fresh air can be input the lungs of patients, when salvagers lightly press the air pump. The air pump automatically rebounds in situ after completing respiratory course. If external air is polluted, an air filter can be connected to the gettering passage in order to purify air input. The utility model has the advantages of simple structure and convenient portability. The portable artificial respirator has no restriction of power supply and oxygen conditions, solving the defect of cross infection, which is suitable for salvaging the patients at the scenes of families, basic units, contingencies, etc.

Description

Portable artificial respirator

The utility model relates to a kind of artificial ventilator.

Traditional method was mouth-to-mouth artificial respiration when some critical patients that suffocate promptly rescued, very easy cross infection, time-consuming, effort.Adopt artificial respirator to help patient respiratory in the hospital, effective, but be subjected to condition restriction such as place, only limit is used in institute, once discloses a kind of " artificial ventilator " Chinese patent CN88219863.7 number, and structure is complicated, though do not need directly to contact with patient's mouth and nose, but still need rescuer gas to be blown into mouth, both unhygienic, also very hard.

The purpose of this utility model is to overcome to be avoided above-mentioned weak point of the prior art and a kind of health care unit of family, basic unit, contingency scene of being applicable to is provided, and rescues the invalid portable artificial respiration equipment of unexpected respiratory arrest.

The purpose of this utility model can reach by following measure:

Telescopic air pump end face is a stiff dough, being convenient to hand uses, one side of air pump is erect volumeter, and be carved with the numeral amount of capacity, volumeter is provided with the vernier card, can move up and down, control air pump capacity, and, connect the elasticity siphunculus by airway again, and connect face shield by airway connection boxlike air-exchanging chamber, boxlike air-exchanging chamber four sides are respectively equipped with exhalation passages, air intake passage, two airways, boxlike air-exchanging chamber inside is divided into two Room, innner and outer by airway, is provided with two way valve or one-way cock between the airway.Air intake passage can external air filter when outside air was contaminated, made in the clean air input patient body.

Accompanying drawing and description of drawings:

Fig. 1 is the portable artificial respiration equipment structural representation.

Fig. 2 is the boxlike air-exchanging chamber structural representation of portable artificial respiration equipment.

Among the figure: 1-vernier card, 2-volumeter, 3-air pump, the 4-base, 5-boxlike air-exchanging chamber, 6-exhalation passages, airway in the 7-, 8-air intake passage, 9-airway, the 10-airway, 11-one-way cock, 12-two way valve, the 13-face shield, 14-elasticity communicating pipe, chamber in the 15-, 16-mistress.

This utility model is described in further detail below in conjunction with accompanying drawing embodiment:

As shown in Figure 1, portable artificial respiration equipment is made the air pump 3 of rugosity by telescopic nontoxic plastics, is hard-caked sediment above, sit 4 one sides and hold up and can roll over the volumeter of putting 2 at the end, be carved with 12 impartial lattice on it, every lattice volume is 100 milliliters, and vernier card moving up and down is arranged on the volumeter, capacity in order to control pump, the maximum effectively capacity of air pump is 1200 milliliters, is controlled at 800 milliliters when the child uses, 600 milliliters of babies.Air pump connects boxlike air-exchanging chamber 5 through airway 9, connect flexibility through airway 10 again and communicating pipe 14 connect face shield 13, boxlike air-exchanging chamber four sides are respectively equipped with exhalation passages 6, air intake passage 8,

airway

9 and 10, chamber 15, mistress 16 in boxlike air-exchanging chamber inside is divided into by airway 7, be provided with two way valve 12 between the

airway

7 and 6, airway 8 is provided with one-way cock 11, and air intake passage 8 can external air filter, makes in the clean air input patient body.Detachable between face shield 13, air pump 3, the air-exchanging chamber 5, be contained in the chest.

To check earlier during use whether each respiration channel of respiratory organ is unimpeded, again face shield is put patient's nose mouth top, pressed the compression pump top once in per 5 seconds, power is wanted evenly when pushing, not too quickly, air enters chamber 15 in the air-exchanging chamber from air pump 3 through airway 9, one-way cock 11 is closed air intake passage 8, and air enters air-exchanging chamber mistress 16 through interior airway 7, and this moment, two way valve 12 was closed exhalation passages 6, air is through airway 10 and communicating pipe 14, through face shield 13, send into the patient oral cavity or (with) nasal cavity, enter patient's lungs, when stopping by compression pump, under the respiratory muscle elastic reaction, extrude gas in the lung, by face shield 13 through communicating pipe 14, airway 10 enters air-exchanging chamber mistress 16, this moment, two way valve 12 was closed interior airway 7, and the gas of exhalation is discharged to the space through exhalation passages 6; When finishing exhalation process, air pump 3 recoils to original position automatically, this moment, valve 11 was opened, fresh air chamber 15 in air intake passage 8 and air-exchanging chamber enters air pump through airway 9, be negative pressure because of the lining is indoor this moment, and two way valve 12 is closed internal channel 7, and is contaminated as outside air, can on air intake passage 8, connect air filter, import again in patient's body after making air cleaning.

Claims
