Description
Technical field
The utility model belongs to a kind of medical instrument, specifically a kind of urethral catheter dedicated in man.
Background technique
Medically, catheter is per urethram inserted into bladder, drains urine.For male, since urethra passes through
A piece elongated catheter is inserted into urethra by penis, and so that urethral dilatation is got up is a very painful thing.In order to mitigate patient
Pain, it is common practice to which per urethra mouth is pushed into local anaesthetics, but with the insertion of urinary catheter, the local anaesthetics that has been pushed into can per urethram mouth
It overflows, influences local anaesthesia effect, so that very pain when intubation.Therefore, the method for existing this intubation anesthesia can't
It is satisfactory, it is necessary to be improved.In the recent period, someone has invented a kind of intraurethral cannula of front end injection anaesthetic, into after bladder
It inflates in toward air bag or injects liquid and fix.Although this pain being intubated when temporarily alleviating intubation, one mistake of anaesthetic drug effect,
Patient will be more painful, when tube pulling due to cannot front administration anesthesia, pull out pipe and be equal to nothing anesthesia, the pain of patient is again
Increase.Therefore, this to be intubated also unsuitable clinical use.
Summary of the invention
The purpose of this utility model is exactly to propose a kind of urethral catheter dedicated in man, enables implementing the same of intraurethral cannula
When urethral wall is carried out incrementally precisely to discharge anaesthetic, tonic anesthesia in due course after intubation, whole process mitigates the pain of patient, with this
Overcome the deficiencies in the prior art.
The utility model proposes this urethral catheter dedicated in man, it has supervisor, tube head, air bag, inflation nozzle and urinal to connect
Head, inflation nozzle have inflation road to be connected to air bag, and urinal connector is connected to supervisor's tail end, it is characterised in that has anaesthetic spray orifice on tube head
It is communicated with anaesthetic feed track I, anaesthetic feed track I is connect with anaesthetic injection head I, and supervisor's wall and urethra corresponding part have urethra anaesthetic
Spray orifice is communicated with urethra anaesthetic feed track II, and anaesthetic feed track II is connect with anaesthetic injection head II, and the inflation road and anaesthetic are defeated
It send and passes through out of supervisor tube wall.
The tube head is tapered, to promote.
The anaesthetic spray orifice is connected to by the interior circuit in supervisor's wall with anaesthetic feed track I.
Anaesthetic spray orifice has multiple, is evenly distributed on around interior circuit.
There is small hose connection between each anaesthetic feed track and anaesthetic injection head.
Urethra anaesthetic spray orifice have it is multiple, be evenly distributed on supervisor wall on.
Pneumatic head and anaesthetic injection head are unidirectional checking head.
The materials such as supervisor medical grade rubber or/and latex are made into.
The utility model, can also be with one man operation generally by two people's compounding practices.In use, a human hand held is responsible for tube head
It is inserted into urethra, every insertion certain depth, for example often into 2-3cm, preprepared anaesthetic syringe is inserted into anaesthetic injection
First I push away spray it is a certain amount of, anaesthetic be pass through anaesthetic feed track I reach tube head at anaesthetic spray orifice outflow, act on urethra carry out office
Portion's anesthesia, such iterative method, gradually anesthesia achievees the purpose that mitigate patient's pain, stops pushing away when tube head reaches in bladder
Into salt water is filled with by stopping injection anaesthetic through inflation nozzle, heaves air bag with fixed supervisor, with urinal and urinal connector company
Connect the intubation work for completing urethra.
After the anaesthetic drug effect discharged when intubation disappears, anaesthetic is supplemented through anaesthetic injection head II, urethra is anaesthetized again.
When needing to transfer to catheter, first the salt water in air bag is pumped with syringe, under making air bag flat, tries that pumping will be responsible for
Out, if patient feels pain at this time, can spray again to urethra through anaesthetic injection head II anesthesia, painless dial-out.
For the utility model compared with existing intraurethral cannula, feature is can be while implementing intraurethral cannula to urethral wall
It carries out incrementally precisely discharging anaesthetic, urethra is anaesthetized in due course after intubation, eliminates the pain of patient in time.

Specific embodiment
As shown in Figs. 1-5, supervisor 4 is essentially identical with existing intraurethral cannula, is made into same material, thickness length,
And with urinal connection urinal connector 7 also with it is existing consistent, tube head 1 has certain taper, to facilitate insertion urethra
Mouthful, the hollow space of supervisor is urethral catheterization road 9, which can be larger to the greatest extent smooth to urinate.
Air bag 3, inflation nozzle 8, connection small hose 5, and inflation road 11 also with it is existing substantially close.
Anaesthetic spray orifice 2 is located on tube head or near tube head, if allowed in manufacture, is opened on the conical surface of tube head as far as possible,
It allows anaesthetic to be sprayed on the forward of supervisor well, anesthesia in time, as far as possible mitigation patient pain is implemented to the urethral wall of expansion.If manufacturing work
It is difficult to retrofit in skill, also anaesthetic spray orifice is opened in immediately following after taper.Referring to Fig. 1-2.
Anaesthetic spray orifice can set 2-4, be uniformly distributed at tube head, so that anaesthetic uniformly sprays around.
For the uniformity for improving anaesthetic injection, an interior circuit 12 is opened at tube head, allows anaesthetic spray orifice and anaesthetic feed track
It is in communication.
The anaesthetic spray orifice of this example is 4, is mutually an angle of 90 degrees between two neighboring anaesthetic spray orifice.
Urethra anaesthetic spray orifice 13 be it is multiple, be usually equally distributed on supervisor's wall corresponding to urethra sum, filled with reaching
Divide the purpose of impartial anesthesia urethral tissue.
As described above, to minimize the diameter of intubation, by inflation road and anaesthetic feed track I 10 and anaesthetic feed track
II 15 are opened in inside the tube wall of supervisor, can be once-forming with mold, it is also possible to which small hose is combined with supervisor.
The structure of anaesthetic injection head I 6 and anaesthetic injection head II and inflation nozzle 8 can be the same, be a macintoss
To non-return air inlet nozzle.
Unmentioned components and label are as described above.
This urethral catheter dedicated in man of the utility model is compact-sized, simple and practical.It clinically tries out, grasps through inventor
Facilitate, is capable of the pain of whole mitigation patient, improves intubation efficiency.Medical staff likes using, it is desirable that uniform technical mark
Standard, batch are supplied.
