Description

Intensive care artificial respirator
Technical Field
The utility model belongs to the technical field of medical instrument, concretely relates to intensive care artificial respirator.
Background
The mode of external chest compression and mouth-to-mouth artificial blowing is mostly adopted when carrying out artificial respiration on severe patients, and the specific process is as follows: the rescuer stands on one side of his head and sucks a breath deeply and blows it into the mouth of the patient. In order to prevent air from leaking out of the nostrils, the nostrils can be held by one hand, and after the chest wall of the patient is expanded, the air blowing is stopped, so that the chest wall of the patient retracts automatically to breathe out air. This is repeated 14 to 16 times per minute. If the patient has serious trauma to the oral cavity or the teeth are tightly closed, the nostril can be blown (the mouth must be blocked), namely mouth-to-nose blowing. The blowing force of the rescuer depends on the specific condition of the patient. The amount of the air blown by an adult is more than 800 ml per time, but not more than 1200 ml per time. Below 800 ml, ventilation may be insufficient; above 2000 ml, the pressure in the pharynx often exceeds the pressure in the esophagus, causing the stomach to inflate and vomiting, causing aspiration. However, this operation is not only troublesome, but also easily causes cross-infection, which increases the difficulty of medical staff.
SUMMERY OF THE UTILITY MODEL
The utility model provides an intensive care artificial respirator, which is simple in operation, time-saving and labor-saving, and can avoid cross infection.
The technical scheme of the utility model as follows: an intensive care artificial respirator comprises an air supply mechanism and an air blowing mechanism, wherein the air supply mechanism comprises a fully-closed folding compression cylinder, a pressure spring is arranged in an internal cavity of the folding compression cylinder, and the folding compression cylinder is spread by the pressure spring; the air blowing mechanism comprises an oval air hood, and two nostril plugs are hung on the air hood through pull ropes; the inner cavity of the folding compression cylinder is communicated with the air cover through an air conveying pipe; an air inlet pipe is arranged on the folding compression cylinder, and a one-way valve is arranged on the air inlet pipe to enable external air to enter the folding compression cylinder in one way only.
Further: and a gas flowmeter is arranged on the gas transmission pipe.
Further: the nostril plug is a silica gel plug.
Further: the gas transmission pipe is provided with a one-way valve to ensure that outside air can only be input into the gas hood through the folding compression cylinder.
Has the advantages that: the scheme provides an intensive care therapy artificial respirator which is simple in structure, not only can simulate artificial respiration, but also can plug the nostrils of a patient by using the nostrils when in rescue, and simultaneously avoids the patient from polluting a gas delivery pipe by using a one-way valve. Especially, in the rescue process, the external air can be rapidly and continuously input into the mouth of the patient, and the amount of the external air filled into the mouth of the patient is observed and controlled through the gas flow meter, so that the shortage or the excess is avoided, the rescue is standardized, and the smooth rescue of the patient is facilitated.

Detailed Description
The invention will be further explained with reference to the following figures and examples:
as shown in figure 1, the utility model discloses an intensive care artificial respirator, which comprises an air supply mechanism and an air blowing mechanism. The design in this scheme to simple structure, convenient operation is suitable.
Firstly: the air supply mechanism comprises a fully-closed folding compression cylinder 3, a pressure spring 4 is arranged in an inner cavity of the folding compression cylinder 3, and the folding compression cylinder 3 is opened by the pressure spring 4. The compression spring 4 is compressed while the folding compression cylinder 3 is pressed; the folding compression cylinder 3 is loosened, and the elasticity of the pressure spring 4 promotes the folding compression cylinder 3 to be quickly unfolded and reset. This facilitates the high frequency of pressing operations by emergency personnel, which also satisfies the need for rapid delivery of sufficient outside air into the patient's mouth, while reducing the overall volume of the collapsible compression cartridge 3.
The air blowing mechanism comprises an oval air hood 7, and two nostril plugs 9 are hung on the air hood 7 through pull ropes 8; the inner cavity of the folding compression cylinder 3 is communicated with the air cover 7 through an air conveying pipe 5. The oval air cover 7 is mainly most suitable for the shape of the lips of a human body, and can completely seal the oral cavity of the human body. Meanwhile, neglecting, the nostrils of the patient are plugged by the two nostril plugs 9, so that the emergency personnel can vacate hands to concentrate on the blowing-up rescue.
An air inlet pipe 2 is arranged on the folding compression cylinder 3, and a one-way valve 1 is arranged on the air inlet pipe 2, so that external air can enter the folding compression cylinder 3 only in one way. The folding compression cylinder 3 is communicated with the external atmosphere through the air inlet pipe 2, and the external atmosphere can only enter the folding compression cylinder 3 through the air inlet pipe 2. The air inlet pipe 2 is provided with a one-way valve 1, so that the folded compression barrel 3 can only enter the air cover 7 from the air delivery pipe 5 when being compressed and is insufflated into the mouth of a patient. When the folding compression cylinder 3 is quickly unfolded and reset through the compression spring 4, air of an external information case enters the folding compression cylinder 3 through the air inlet pipe 2. Not only realizes the continuity, but also ensures that the mouth of the patient can be filled with enough external air in a certain time.
The specific using steps are as follows: firstly, pressing the air hood 7 to the mouth of a patient with one hand, and paying attention to the fact that the mouth of the patient needs to be opened; the two nostril plugs 9 plug the nostril of the patient 9, prevent the external air from not fully entering the patient's thorax; the folding compression cylinder 3 is pressed and released by one hand and then pressed again so as to simulate artificial respiration to rescue a patient; after the rescue is finished, the air hood 7 is released.
It should be noted that: the air inflow of the patient needs to be carried out according to medical regulations, and the air inflow in the patient is ensured not to exceed a specified value. Therefore, in further optimization, the gas flowmeter 6 is arranged on the gas pipe 5, and the rescue personnel can judge the external air amount filled into the patient body through the gas flowmeter 6 so as to ensure that the rescue is smoothly carried out according to the regulation. The nostril plug 9 is preferably a silica gel plug, is clean, sanitary and easy to clean, and has elasticity to adapt to different patients.
Patient is in the in-process by the first aid, the phenomenon of outwards vomiting or spitting out gaseous in the body may appear, and in order to avoid the gaseous gas that patient spit to enter into gas-supply pipe 5, also can set up check valve 1 on the gas-supply pipe 5, just so can avoid gas-supply pipe 5 to receive the pollution, clean operation fast of being convenient for of gas-supply pipe 5 in later stage.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
