Urethral sound by adopting the above technical scheme, the end thread in straight line portion are connected with removably hand-held lever,
Hand-held lever is unloaded after use, and is mounted on another urethral sound end of the same race by disinfection, can be carried out next time
Operation, and probe Zhou Jing is adjustable during use for urethral sound, re-starts replacement without retrieving, avoids patient again
Once by pain.
It further limits, is equipped with filter screen in the preceding Non-return air valve and the rear Non-return air valve.
It further limits, second gasbag outer surface is equipped with anti-skid chequer.
It further limits, is provided with scale on the straight line portion.
It further limits, the air inlet is at least provided with two.
The utility model compared with the prior art for, be provided with removably hand-held lever, and be equipped in hand-held lever
Air bag is inflated to the first air bag of urethral sound end by hand-held lever, makes its expansion, is without replacement urethral sound
The Zhou Jing of urethral sound can be increased, be easy to use, clinical diagnosis and treatment is convenient for.

Corresponding mark is respectively as follows: the bending section 1-, the straight line portion 2- in figure, and 3- holds lever, the end 11-, the first air bag of 12-,
13- air inlet, 21- riffled tube, 22- scale, 31- male-pipe, Non-return air valve before 32-, Non-return air valve after 33-, 34- second
Air bag, 35- filter screen, 36- anti-skid chequer.
In order to which those skilled in the art may be better understood, with reference to the accompanying drawings and examples to the utility model
Technical solution further illustrates.
Urethral sound as shown in Figure 1, Figure 2, Figure 3 and Figure 4 includes the body of rod and hand-held lever 3, the end of the body of rod with
The nose threads connection of hand-held lever 3, the body of rod include bending section 1 and straight line portion 2, the end of the bending section 1 with it is described
The front end of straight line portion 2 is connected to and is integrally formed；The diameter of the bending section 1 is less than the diameter of the straight line portion 2, the bending section
1 front end is equipped with arc-shaped end 11, and the apical lateral of the bending section 1 is additionally provided with the first air bag 12, first air bag 12
It is connected to the bending section 1 by air inlet 13.The end of the straight line portion 2 is equipped with riffled tube 21.The hand-held lever 3 wraps
Include male-pipe 31, preceding Non-return air valve 32, rear Non-return air valve 33 and the second air bag 34.
Non-return air valve 33 is set to the rear end of second air bag 34 after described, and the preceding Non-return air valve 32 is set to described the
The front end of two air bags 34, the male-pipe 31 are set to the front end of the preceding Non-return air valve 32, preceding 32 He of Non-return air valve
Filter screen 35 is equipped in Non-return air valve 33 after described.Second air bag, 34 outer surface is equipped with anti-skid chequer 36.The straight line
Scale 22 is provided in portion 2.The air inlet 13 is at least provided with two.
The utility model is before use, straight line portion 2 and hand-held lever 3 are connected by riffled tube and male-pipe
It connects, urethral sound is goed deep into the urethra of patient, the length of bending section is regular length, by the quarter for observing straight line portion surface
Degree, gos deep into endo-urethral depth to observe, when the Zhou Jing of urethral sound is smaller, can squeeze the second air bag, make in the second air bag
Air be discharged out of preceding Non-return air valve, pass sequentially through straight line portion and bending section and enter in the first air bag, due to the first air bag
Front-end and back-end are respectively equipped with preceding Non-return air valve and rear Non-return air valve, therefore will not flow back from the gas that the second air bag is discharged,
It is able to enter in the first air bag, expands the first air bag, to increase the Zhou Jing of urethral sound.Simultaneously hand-held lever surface also
Equipped with anti-skid chequer, hand is slipped when can prevent from squeezing the second air bag, and the mistake in preceding Non-return air valve and rear Non-return air valve is arranged in
Strainer for filtering air in impurity, prevent dust bacterium etc. pollution bending section and straight line portion inner cavity.After usage,
It extracts urethral sound out, hand-held lever is dismantled with straight line portion, the gas in the first air bag is discharged from the end of straight line portion, the first gas
Capsule restores to the original state, to be the end recovery default Zhou Jing of urethral sound；By the new straight line portion for passing through disinfection and hand-held lever
Connection can carry out diagnosis and treatment for next bit patient.
Urethral sound provided by the utility model is described in detail above, the explanation of specific embodiment is only intended to
Help understands the method and its core concept of the utility model.It should be pointed out that coming for those skilled in the art
It says, without departing from the principle of this utility model, several improvements and modifications can be made to this utility model, these change
Into in the protection scope for also falling into the utility model claims with modification.
