It relatively rotates, to prevent foley's tube from reversing.
As shown, in a specific embodiment of the present invention, guide chute 3 is set to pusher 1, guide runner 8
It is set to casing 6.
In the utility model embodiment, at least to be set on casing 6 convenient for pushing pusher 1 to slide to 6 direction of casing
Handle 5 is set, the finger of handle 5 is arranged at least on casing 6 can only be arranged handle 5 on casing 6, or can be in casing 6 and pusher 1
On be respectively provided with handle 5.In this way, when in use, clasping the handle 5 on casing 6, thumb using remaining four finger in addition to thumb
Refer to the handle 5 clasped on pusher 1 or pusher 1, it is opposite to slide pusher 1 and casing 6 relatively.
In Fig. 1 and specific embodiment shown in Fig. 2, handle 5 is provided on propeller and casing 6, and handle 5 is
The annular that can cooperate with finger.
It is additionally provided with slidably on casing 6 in the utility model embodiment for the connection convenient for casing 6 and pusher 1
Connection swivel nut 7,1 end of pusher be provided with connect swivel nut 7 cooperation external screw thread, connection swivel nut 7 and external screw thread cooperation will
Casing 6 is connected to pusher 1.Further, to avoid use process middle sleeve 6 from separating with pusher 1, as shown in Fig. 2, even
It connects swivel nut 7 to be set on casing 6 and between handle 5 and guide runner 8, connect swivel nut 7 with guide runner 8 using handle 5
It is limited.At the same time, the cooperation for connecting swivel nut 7 and pusher 1 makes guide chute 3 form an enclosed slot, to casing 6
Sliding is limited.
Cooperate with pusher 1 to have both casing 6 and to the effect that foley's tube is oriented to, implement in the utility model
In example, casing 6 includes multiple pipeline sections, along one end to 9 direction of elbow that casing 6 and pusher 1 cooperate, each pipe of casing 6
The diameter of section is respectively less than the diameter of a pipeline section, as shown in Fig. 2, one end diameter that casing 6 and pusher 1 cooperate is maximum, with
The intracavity diameter of pusher 1 is substantially suitable, when being that pusher 1 is slidably matched, can be avoided and the problem of swing of casing 6 occurs,
Thereafter pipeline section diameter is sequentially reduced, to avoid shaking of the foley's tube in casing 6, realizes accurate output.
Above-mentioned technical proposal is advanced optimized, in the utility model embodiment, passes through guiding between two neighboring pipeline section
Taper Pipe connection.
Foley's tube must with pusher 1 is relatively fixed to push foley's tube forward using pusher 1, to reach
This purpose, in the utility model embodiment, pusher 1 is formed with far from one end of casing 6 for the tail with foley's tube
Hold the horn mouth 4 of standard point cooperation.
Below with reference to above-mentioned specific embodiment to the application method of Eustachian tube foley's tube embedded device provided by the present application
It is described in detail.
Firstly, assembling pusher 1 and casing 6, are directed at the guide chute 3 on pusher 1 for the guide runner 8 on casing 6,
One end with casing 6 far from elbow 9 is provided with externally threaded one end from pusher 1 and is inserted into, then with connection swivel nut 7 and pusher 1
External screw thread cooperation, pusher 1 is connect with casing 6, and casing 6 is inserted into bottom along guide chute 3, then passes through locking piece 2
Pusher 1 and casing 6 are locked；
One end by foley's tube from pusher 1 far from casing 6 is formed with one end insertion of horn mouth 4, when sacculus is led
When pipe is inserted into nearly midpoint, locking piece 2 is unclamped, propeller 1 and casing 6 are pulled open, contradicts guide runner 8 with swivel nut 7 is connect, so
Lock locking piece 2, fixed pusher 1 and 6 position of casing again afterwards；
Foley's tube is continued into, when the horn mouth of foley's tube tail end standard point insertion 1 tail end of propeller, illustrates ball
Ductus bursae has been fixed, and the operation of Eustachian tube balloon dilatation can be carried out.
When work, locking piece 2 is unclamped, propeller 1 is promoted to 6 direction of casing, foley's tube is pushed into pharynx drum through casing 6
Pipe, in the process, should control the fltting speed of propeller 1, to avoid damage Eustachian tube, slide when guide runner 8 reaches guiding
Stop when 3 end of slot, fasten locking piece 2, then connects water injecting pump in foley's tube tail end, water filling pressurization carries out Eustachian tube expansion
Art.
After end operation, foley's tube is taken out, connection swivel nut 7 is unscrewed, separates propeller 1 and casing 6, be respectively washed and disappear
Poison.
Each embodiment in this specification is described in a progressive manner, the highlights of each of the examples are with other
The difference of embodiment, the same or similar parts in each embodiment may refer to each other.
The foregoing description of the disclosed embodiments can be realized professional and technical personnel in the field or using originally practical new
