Abstract

The present invention discloses a nest-used trachea cannula airbag system for eliminating trachea injury, when a cannula nested airbag in bronchus generates a pressure, so as to reduce the injury to the trachea to the lowest limit. Different from a working principle of a currently used endotracheal tube, a second elastic airbag is used in the process of assisting breath, breath pressure performs ventilation for the inside elastic airbag, the elastic airbag is placed in the nested airbag, pressure reduction is assisted through four holes having the diameter of 4mm, so that the elastic airbag is opened and expanded inside a second airbag tube. Therefore, the trachea below the trachea cannula nested airbag is not kept to be under a constant pressure, tissue damage cannot be caused. The pressure is the fixed, the trachea cannula nested airbag has a 6-8cm water pressure effect, so as to generate a resistance for pressure of secreta entering into the lung from the mouth and body fluid.

Description

Eliminate the nested use tracheal intubation gas-bag system of trachea infringement

Technical field

The present invention relates to a kind of device, this device can reduce in the trachea of expansion, under the impact that is subject to excess pressure, and the air bag nutritive issue pathological changes and the damage that in tissue, occur.

Background technology

In current application intubate (process that endotracheal tube inserts) use procedure, with 25 centimeters of water pressure, nested use tracheal intubation air bag is inflated.If pressure remains on reduced levels, patient can not reach desired standard by artificial respiration, can not get the air capacity of needed by human body, also can inhale because oral cavity breathing causes mistake, makes secretions and body fluid in mouth enter pulmonary.According to analyzing and research, the report of proposition claims, this pressure can make the inner epidermis of trachea generate bubble, produces pressure and causes trachea epidermal cell necrosis, causes trachea inner narrow and and then tear trachea.Most of this infringements are permanent, therefore most important.

Summary of the invention

The object of this invention is to provide a kind of nested use tracheal intubation gas-bag system of eliminating trachea infringement, when the nested air bag of endobronchial intubation produces pressure, the infringement that trachea is caused is minimized.

Nested use tracheal intubation gas-bag system of the present invention, is that to reduce endotracheal tube system failure be operation principle as far as possible, controls the variation of gasbag pressure by operation, guarantees the breathing equipment of normal suction and expiration.

The operation principle that is different from the endotracheal tube of current use, in the process that helps to breathe, use the second elastic bag, respiratory pressure ventilates to inner elastic bag, elastic bag is placed in nested air bag, and the hole that is 4 millimeters by four diameters helps blood pressure lowering, make the elastic bag expansion that is opened in the second airsac tube inside.Therefore, the trachea of the nested air bag of tracheal intubation below does not remain under a constant pressure, can not cause tissue damage.Because pressure is on the fixing nested air bag of tracheal intubation, by the Water Pressure that has 6-8 centimetre, oral cavity is entered to the secretions of pulmonary and the pressure of body fluid produces resistance.

Because inner side air bag is resilient, airbag gas is during by emptying, and the probability that pressure can avoid the secretions of fluid to enter inner side air bag, also can prevent from accumulating in the air bag of inner side.The pressure control device of inflating by nested gas generator for air bag, allows barometric information according to the mobile device of air bag, at the Water Pressure lower gasbag of 6-8 centimetre, will expand.

Gas-bag system of the present invention can be applied in all oral cavities, nasal cavity and endotracheal intubation and bronchotomu.In each respiration phase, along with the nested gasbag pressure in outside changes, apply mechanical massage to support shuttling movement simultaneously.External nested air bag is according to traditional application mode, and inflation reaches trachea area.

The present invention can produce the nested gas-bag system that pressure changes, without any need for other electronics or plant equipment.When respirator, anesthesia equipment and the respiratory circuit without any extra parts or accessory.

The specific embodiment

With reference to figure 1-4, the nested use tracheal intubation gas-bag system of elimination trachea infringement of the present invention comprises exterior airbag 1, is equipped with nested inflation pressure control device, and controlling the blowing pressure is 6-8 centimeters of water pressure.In external nested inside, there is the second air bag 2(of more high resilience structure with reference to figure 1).Under the help of this air bag, 4 pores 3 of airbag-releasing on endotracheal tube surface, diameter is that the hole of 4 millimeters is (during application, according to the diameter of pipe, change, the diameter in hole will change) pressure of elastic bag is applied in patient's induction Repiration, induction as much as possible is air-breathing and pressure of inspiration(Pi) (25 centimeters of water pressure) is reflected in the nested air bag of inflation trachea outside.In exhalation process, the intrasystem pressure of elastic bag disappears, and trachea enters in the inner chamber of lumen, thereby the nested gasbag pressure of endotracheal tube is provided completely by the air hose providing in interior tubing, by constantly keeping pressure, its tissue injury causing is minimized.In addition, the interior shape (with reference to figure 2) after elastic bag 2 venting does not allow secretions to be accumulated into bubble.The total surface area of the hole that nested air bag is open must equal the interior tube chamber surface area of pipe used.Structure and arrangement that these holes are open, can not cause air turbulence, prevents that secretions from gathering, and can't cause breathing noise.

With reference to the top view a in figure 4, the position of pore 3 can be very clear; From side view b, the position of pore 3 is also high-visible.

Use the operation of the gas-bag system of nested endotracheal tube, by laboratory research (table 1) designation system, described pressure logic the graphing curve of designed gas-bag system operation.Pressure (table 1-1) in ventilation pressure in table 1 (table 1-2) and air bag is measured simultaneously.This gas-bag system design object, is intended to be applied to all oral cavities, nasal cavity and endotracheal intubation and bronchotomu.

In each respiration phase, along with the nested gasbag pressure in outside changes, apply mechanical massage simultaneously, support shuttling movement.External nested air bag is according to traditional application mode, and inflation reaches trachea area.

This produces the nested gas-bag system that pressure changes, and any other electronics or plant equipment are unwanted.Respirator, anesthesia equipment and respiratory circuit are without any extra parts or accessory.

Use the pressure control device of nested airbag aeration, can make the blowing pressure achieve one's goal and reach 6-8 centimeters of water pressure.
