Utility model content
Attract operation to conveniently and effectively carry out ear, the utility model provides a kind of adjustable type ear sucking head.
To achieve these goals, the technical solution that the utility model is taken is as follows：
A kind of adjustable type ear sucking head, the vacuum cavity including being in hollow-core construction, one end of vacuum cavity is inserted with leading
Pipe, the other end of vacuum cavity are equipped with air inlet, and be equipped with the adjusting part for adjusting air inlet port size, vacuum cavity
Side wall is equipped with the bleeding point for connecting aspiration pump；The front end bending of the conduit, and the axis angle of bending place for 125 ~
145℃；The adjusting part includes the first baffle and second baffle that are mutually slidably matched, and second baffle is far from first baffle
One end is fixedly connected through and out vacuum cavity, the first baffle with vacuum cavity, the second baffle and vacuum cavity
It is slidably connected.
Preferably, the conduit is transparent, and the nozzle of catheter proximal end uses round-corner transition.
Preferably, the outer wall of vacuum cavity is equipped with anti-sliding burr.
Preferably, second baffle and the side of first baffle joint are equipped with sliding slot, and first baffle is equipped with and sliding slot
The protrusion being adapted.
Preferably, second baffle stretches out one end of vacuum cavity equipped with slot hole.
Further, the conduit is made of polyvinyl chloride pipe, and the vacuum cavity is made of rubber.
The utility model uses medical polyvinyl（PVC）The conduit of all-transparent is made in material, can be clearly apparent in conduit
Between the attraction substance that flows through, avoid shutting out the light when using and the sight of doctor；Catheter proximal end reaches passivation mesh using fillet
, easy damaged skin of external auditory canal, does not avoid the generation of bad complication；By the adjusting part of vacuum cavity one end, hand can be used
Second baffle is pushed and pulled to control vacuum magnitude, can fast adjust attraction speed.The utility model is convenient for carrying, by replacing conduit
Cross-infection can be effectively prevented from, it is reasonable in design, the working time of medical staff is greatly saved, it is highly practical, easily
In large-scale promotion.

Specific embodiment
As shown in Fig. 1 ~ 6, a kind of adjustable type ear sucking head, the vacuum cavity 2 including being in hollow-core construction, vacuum cavity 2
Upper end be equipped with connector 201, and inserted with conduit 1, the lower end of vacuum cavity 2 is equipped with air inlet 203, and be equipped with to adjust
The adjusting part of 203 size of air inlet is saved, the side wall of vacuum cavity 2 is equipped with the bleeding point 202 for connecting aspiration pump；Negative pressure
The outer wall of 2 lower part of cavity is equipped with anti-sliding burr 204.The front end of the conduit 1 bends 104 in circular arc, and conduit 1 is bent by circular arc
104 are divided into two sections, i.e. the first pipe portion 101 and the second pipe portion 102, the longitudinal center line of the first pipe portion 101 and the second pipe portion 102
The angle of longitudinal center line is about 135 DEG C.The adjusting part includes the first baffle 3 being mutually slidably matched and second baffle 4,
The first baffle 3 includes the first rounded plate portion 301, and the left side of the first plate portion 301 is equipped with the notch 304 of rectangle, and first
The outer circle side of plate portion 301 is seamlessly connected with the inner wall of vacuum cavity 2, and the right side of the first plate portion 301 is extended with the connection of rectangle
