Description
Technical field
The utility model is related to a kind of clinical treatment urethral catheterization device, more particularly to a kind of urethra section is partially with administration side
The urethral catheterization device in hole.
Background technology
Clinically need the patient of progress surgical operation under general anesthesia, it usually needs self retaining catheter, the state of an illness is complicated, follows
The unstable patient of ring, also needs to the retention catheterization device of longer time after operation.Long-time self retaining catheter causes to suffer from
Person's urethra discomfort is clinically common problem.The catheter assembly clinically used at present is by catheter main body, head
End band water filling sacculus, tail end are made of catheter main body draining hole and sacculus water filling port.Catheter main body is to the stimulation of urethra
The main reason for causing discomfort, it is therefore desirable to which traditional urethral catheterization device is improved.
Utility model content
The technical problems to be solved in the utility model is the irritation for improving traditional catheter urethra portion to urethra, is proposed
A kind of catheter that side opening is administered with local anaesthesia for part, by interruption by the way that urethra portion local administration, it is long to mitigate patient
Malaise symptoms caused by phase retention catheterization device.
The technical solution of the utility model is:A kind of urethra section is partially with the urethral catheterization device of administration side opening, including urethral catheterization
Pipe main body, catheter fore-end and catheter end section, the end section have extend out from main body medicine-pouring hole,
There is administration side opening, the administration side opening and the note inside urethral catheterization hole and air-filled pore, the catheter main body and fore-end
Medicine hole is connected to by communicating pipe, and there is the fore-end drug release section, the drug release section to have release hole, the release hole and institute
State administration side opening connection.
Preferably, the administration side opening is located at the both sides inside the catheter main body and fore-end and is symmetrical arranged,
The release hole is located at the both sides of drug release section and is symmetrical arranged.
Preferably, in medicine-pouring hole and air-filled pore in place of catheter main body extends out, the internal diameter of medicine-pouring hole and air-filled pore
Change from big to small from end section forward end part.
Preferably, the fore-end also has balloon segment.
The utility model has the beneficial effects that it is uncomfortable to mitigate patient's urethra caused by needing long-time self retaining catheter
Symptom.

Specific implementation mode
Below by embodiment, the utility model is described in further detail, and purpose, which is only that, more fully understands that this practicality is new
The research contents of type and unrestricted the scope of protection of the utility model.
As shown in figs. 1 and 4, urethral catheterization device (urethral catheterization of a kind of urethra section of the utility model partially with administration side opening
Pipe), including catheter main body 1, catheter fore-end 2 and catheter end section 3.The end section 3 has from main body
Medicine-pouring hole 31, urethral catheterization hole 32 and the air-filled pore 33 to extend out.During urethral catheterization hole 32 and catheter main body 1 are substantially having the same
Mandrel line, and medicine-pouring hole 31 and air-filled pore 33 have certain angle with catheter main body 1.
With reference to figure 3,5 and 6, the catheter main body 1 and fore-end 2 have an administration side opening 4, the administration side opening 4 and
The medicine-pouring hole (delivery tube) 31 is connected to by communicating pipe 5.The administration side opening 4 has 2, is located at urethral catheterization device and (leads
Urinary catheter main body 1 and fore-end 2) internal both sides.Fig. 3 of the utility model and Fig. 7 of the prior art are compared it is found that this practicality
It is novel that administration side opening 4 is increased inside catheter.
With reference to figure 2, there is the fore-end 2 drug release section 21, the drug release section 21 to have release hole 6, the release hole 6
It is connected to the administration side opening 4.The release hole 6 is located at the both sides of drug release section 21 and is symmetrical arranged.The fore-end 2 also has
There is balloon segment 22.The length of the balloon segment 22 and drug release section 21 can be 60mm.
In end section 3, in medicine-pouring hole 31 and air-filled pore 33 in place of catheter main body 1 extends out, the i.e. B-B of Fig. 4
The internal diameter in the region between line and catheter main body 1, holes 31,33 is (i.e. certainly backward to from the D lines of catheter main body 1 from line B-B
Before) change from big to small, such as can be from 2mm gradual changes (transition) to 1mm.
The catheter of the utility model and the mode of operation of current existing catheter are essentially identical, the difference is that increasing
Local drug delivery device is added, by injecting medicament to medicine-pouring hole 31, medicament enters the administration side opening 4 of both sides through communicating pipe 5, and passes through
Release hole 6 carries out local administration to urethra portion, can mitigate patient's urethra uncomfortable diseases caused by needing long-time self retaining catheter
Shape.
Obviously, those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate this
Utility model, and being not used as the restriction to the utility model, if in the spirit of the utility model, to
The variation of the upper embodiment, modification will all fall Claims scope in the utility model.
