Abstract
The utility model relates to a once-used pneumothorax needle, using for pneumothorax exhaust of a human body. A hollow needle tube is provided. One end of the hollow needle tube is fixed on a tube cap which has the function of unidirection exhaust. An exhaust passage is arranged on the tube cap. When the pneumothorax needle is used, patients can move and can not undergo pains of repeated suction and closed drainage.
Description
This utility model relates to a kind of medical apparatus and instruments, and particularly a kind of apparatus that takes out medium in the human body is for example discharged in the torso model and accumulated the employed apparatus of gas.
Pneumothorax is multiple pulmonary disease and thorax damage, common secondary diseases such as air pressure environmental catastrophe, and usually bring great misery to the patient, even threat to life.In the treatment of pneumothorax, at first consider aerofluxus, remove pressure symptom by aerofluxus the lung utmost point is early opened again.People have used various devices to be used for the aerofluxus of pneumothorax.For example Chinese utility application number is 88294114.2, and name is called " the thoracic cavity gas-liquid attracts drainage device "; Application number is 89202897.1, and name is called " pneumothorax air extractor "; Application number is 91207954.1, and name is called " the pocket drainage device of pneumothorax "; The patent No. be 2L92229643. *, name is called " miniature pneumothorax drainage system " etc., but above-mentioned exhaust apparatus will use air-extractor, fixedly patient posture is stiff, repeatedly bleed, so patient is painful big, easy infection, accumulative total expense height, therefore a kind of safe in utilization, convenient, the pneumothorax aerofluxus apparatus that can reduce patient's misery presses for.
The purpose of this utility model then is to provide a kind of pneumothorax exhaust apparatus with above-mentioned desired function.
For achieving the above object, scheme of the present utility model is: be used for the deflated disposable pneumo brooch of human body pneumothorax, be provided with a hollow needle tubing, an end is fixed on the pipe cap with unidirectional degassing function, has the exhaust passage on the pipe cap.
When adopting the described device of such scheme, when the gas pressure in the pleural space was malleation, gas was discharged by the pipe cap with unidirectional degassing function, when gas pressure is closed during for negative pressure, outside gas can not enter in the body, thereby has realized the purpose of this utility model.
Below in conjunction with diagram and embodiment more detailed description scheme of the present utility model.
Fig. 1 is the installation diagram of disposable pneumo brooch;
Fig. 2 is the front view of disposable pneumo brooch pipe clamp;
It among Fig. 1 the structure of a specific embodiment, a hollow needle tubing (1) is arranged, needle point has side opening, its upper end is fixed on the pipe cap (2), have annular groove (3) on the end face of described pipe cap (2), annular groove (3) is divided into cylinder boss (4) and outer shroud (5) with end face, and the center of boss (4) is drilled with on the shoulder hole (6), hollow needle tubing (1) promptly is fixed in the macropore of shoulder hole (6), and its aperture penetrates boss (4).The cylindrical of outer shroud (5) is carved with the slightly little locating ring of diameter (7).Be provided with a cap (8), the diameter of the locating ring (7) of the internal diameter of cap (8) and pipe cap (2) coincide, so that can more closely be fixed on the pipe cap (2).The interior resonator end surface of cap (8) has a circle boss (9), is cavity (10) in the boss (9), and the end face of the end face of boss (9) and outer shroud (5) can be fitted.
Between the end face of the boss (9) of the end face of pipe cap (2) and cap, be pressed with an elastic film (11) during assembling, elastic film can be bonded on the end face of outer shroud (5), the elastic film of present embodiment is a rubber sheet, its thin film is pre-designed, get final product aerofluxus when requiring the pneumothorax internal pressure to reach the 1-2cm water column pressure, can close during negative pressure.Described rubber sheet is sealing the aperture on the boss (4) tightly when confined state, when gas pressure surpassed the 1-2cm water column, gas backed down sheet rubber (11), is discharged by exhaustor (12) by boss (4) cavity on every side.Exhaustor (12) is a rubber hose, and an end links to each other with pipe cap by joint (13), and the other end is connected with air filter housing (14), and described air filter housing (14) is equipped with dredges hole material (15), and cover cap has aperture on (16).The effect of filter mantle is to prevent that antibacterial from entering in the body.
Pipe clamp (17) is housed on escape pipe (12), plays folder and close exhaustor.
When this disposable pneumo brooch uses,, be provided with the hollow needle tubing of four kinds of length according to patient's thoracic wall thickness.During installation, get patient's side chain bone center line and save two intercostals or pneumatosis position, routine disinfection, local anesthesia, just can understand thoracic wall thickness by local anesthesia and (or pass through X-Ray, definite thoracic wall thickness such as ultrasound wave), select vertically to thrust thoracic wall, cover dressing and get final product than the pneumothorax needle of the long 0.5-1.5cm of thoracic wall thickness.Gas can be discharged through exhaustor in the thoracic cavity.Treat that aerofluxus stops, confirming through x-Ray that lung is swollen and rise or be compressed in below 20% that folder closes exhaustor and observes, if compression zone no change or diminish can be dialled except that the pneumothorax needle.
Said apparatus is through clinical use, uses very conveniently, and patient is movable, do not experience and bleeds repeatedly and the misery of closed drainage, and can not bring bigger misery to patient when settling.
In sum, this utility model is effective.
