Abstract
The utility model relates to an aspirator for a pneumothorax device, which is a clinical medical apparatus, comprising a break-in exhaust pipe which is provided with an exhaust one way valve. The exhaust one way valve comprises a valve body, a valve base which is provided with a gas outlet opening and which is screwed with the valve body, an active valve which is correspondingly installed on the gas inlet opening of the valve body, and springs which are arranged between the active valve and the valve base. The utility model has the advantages of simple structure, convenient usage, advantaged clinical application, and convenient to the patients and staffs.
Description
Technical field
This utility model relates to a kind of pneumothorax exhaust apparatus, is the clinical treatment apparatus.
Background technology
Clinically, pneumothorax (being the pleural space pneumatosis) is the common disease symptom, therefore needs correct aerofluxus with relief of symptoms.Up to the present, clinically continuing to use traditional simple and easy method always,, inserting the insertion depth of exhaustor in water by control and adjust the aerofluxus situation inserting in the water that exhaustor inserts liquid bottles.General insertion depth is 2-3cm, that is the control pressure at expulsion is the high water column of 2-3cm.Use inconveniently, especially needs of patients moves, when movable, also will accompany and move liquid bottles, and, the bad especially accurate assurance of the insertion depth of exhaustor in water.
Summary of the invention
The purpose of this utility model is to provide a kind of pneumothorax exhaust apparatus simple in structure, easy to use
Pneumothorax exhaust apparatus described in the utility model has one to insert exhaustor, and exhaustor is provided with exhaust check valve.
By the design exhaust check valve, can control the aerofluxus situation easily, simple in structure, easy to use, the patient can voluntary activity, and has prevented the air-flow adverse current, and is safe and reliable.
Exhaust check valve can have multiple, and simple structure situation can be made up of valve body, valve seat, valve alive and spring, and valve body is connected with valve seat, and the valve correspondence of living is arranged on the air inlet of valve body, and valve seat is provided with the gas outlet, lives in being provided with spring between valve and the valve seat.The pressure of spring is used for determining deflated pressure.With valve body and seat design for being threaded, the spacing between regulating valve seat and valve body easily, the pressure of spring obtains adjusting thereby make therebetween, to regulate suitable pressure at expulsion.
For the purpose of safe and sanitary, can on the gas outlet of valve seat, set up gland, in gland, be fitted with drainage screen.
This utility model is simple in structure, and is easy to use, is beneficial to clinical practice, makes things convenient for patient and medical personnel.
Description of drawings
Fig. 1, this utility model one example structure sketch map.
Among the figure: 1, insert exhaustor 2, valve body 3, valve seat 4, gland 5, drainage screen 6, spring 7, live valve 8, valve body air inlet.
The specific embodiment
The utility model is described in further detail in conjunction with the foregoing description accompanying drawing.
As shown in the figure, pneumothorax exhaust apparatus described in the utility model, have one to insert exhaustor 1, exhaustor 1 is provided with exhaust check valve, and exhaust check valve is made up of valve body 2, valve seat 3, valve 7 alive and spring 6, valve body 2 is threaded with valve seat 3., living is provided with spring 6 between valve 7 and the valve seat 3, and valve 7 correspondences of living are arranged on the valve body air inlet 8, and valve seat 3 is provided with the gas outlet, the valve seat gas outlet is provided with gland 4, is fitted with drainage screen 5 in the gland 4.
During use, will insert exhaustor 1 and insert in the thoracic cavity, under the normal condition, the effect of spring 6 be arranged, the valve 7 of living closely contacts with valve body 2, and air-flow is obstructed, when aerothorax is big, promote spring 6 retractions, live 2 of valve 7 and valve bodies form airspace, and intrathoracic gas can be discharged.The control of pneumatosis pressure can be regulated with valve seat 3 connecting threads by spring 6 and valve body 2.Drainage screen 5 in the gland 4 has the effect of filtration, purification air-flow.Exhaust check valve has non-return effect, has prevented the air-flow adverse current.
