Abstract

The utility model relates to an air-sac fixed disposable bladder syringe, which is the improvement for an original disposable bladder syringe. An inflation tube and an air sac are additionally arranged on the utility model, and parts of urethral catheter segments of a urethral catheter are made into double-layer wall tubes. The air is inflated from an air valve, air flow enters the wall cavity of the urethral catheter through the inflation tube to enter the air sac through a small through hole which is left by an outer wall layer to realize bladder injection without outer fixation. The inner fixation further reduces chance of bacterial infection of patients; the utility model can relieve the referred pain of the outer fixation when the patients carry out urethral catheterization and can relieve pain when bladders are torn.

Description

The fixed disposable use bladder syringe of air bag

This utility model belongs to medical supplies, be a kind of being applicable to dysuria patient urethral catheterization is arranged, and the patient of urinary tract infection and tumor disease makes the utensil of bladder medicinal liquid perfusion therapy.

Existing disposable use bladder syringe (patent No. 94242812.9), with bladder urethral catheterization before this, the perfusion utensil is compared, reaching under the situation of same therapeutic effect, have easy and simple to handle, reduce infection chance, meet the plurality of advantages that stopping state can in time be handled, but beg till the present, no matter be which kind of urethral catheterization, the perfusion utensil all needs to do external fixation in use, otherwise conduit can come off from the urethral orifice downslide, and the easiest method of external fixation is with adhesive plaster conduit to be sticked on the skin and flesh, this certainly will involve sense, paste loose landing in the same old way, unavoidable pain when pasting to such an extent that tightly take off down, and when pasting, operation also has opportunistic infection near focal zone.

The fixed disposable use bladder syringe of the air bag of the novel proposition of this reality can not adopt external fixation and realizes internal fixation, reaches to reduce the patient suffering, further reduces the purpose that infects.

Technical solution of the present utility model is as follows:

Structural representation when accompanying drawing 1 is this utility model airbag aeration

Among the figure: 1 for air bag, 9 for air valve, 10 is little perforation for gas tube, 8 for linking piston, 6 for focus position, 7 for circular hole, 5 for mediation sacculus, 4 for catheter, 3 for water inlet pipe, 2.

The utility model has comprised the water inlet pipe of former disposable use bladder syringe 1, the parts such as catheter 2, dredging sacculus 3, circular hole 4, and increase on this basis If gas tube 7, air bag 8, and under 2 of the catheters dredging sacculus 3 with circular hole 4 On one section be the double wall pipe of hollow; The upper end of its gas tube 7 is connected with one Air valve 9, the dredging sacculus is passed in its stage casing, and the lower end passes into the double-layer tube wall of catheter 2 In; On its its 8 catheters of air bag, the 2 lower end circular holes 4, be enclosed within catheter Outside 2, and leave little perforation 10 around the outer tube wall of this section catheter, make catheter The wall chamber communicates with airbag chamber.

(the die sinking injection moulding once to require to make the utility model according to said structure Moulding, air bag are to get high-elastic thin-walled material to be glued at indication location, catheter bottom Put) aseptic sterilization wrap. During use the catheter bottom is inserted patient's urethra (focus 6 among the figure), and make air bag partly also enter urethral orifice, get common medical Syringe is squeezed into gas from air valve 9, and gas enters the bilayer of catheter from gas tube 7 The tube wall chamber also enters air bag 8 by little perforation 10, and air bag is heaved, and catheter is not then Can be from urethral orifice whereaboutss of trying to shirk responsibility, needn't carry out again outer fixing, and other perfusion use Method all is same as disposable use bladder syringe, and is to be used complete, uses syringe From the air valve gas bleeding, air bag is flat lower, extracts catheter and gets final product.

To sum up, this utility model has further reduced the patient and has been subjected to the chance of bacterial infection, and involving sense and taking off pain when tearing when having exempted from but that patient accepts external fixation.

Claims

1, a kind of fixed disposable use irrigation of bladder device of air bag that has comprised water inlet pipe 1, catheter 2, dredged sacculus 3, circular hole 4, it is characterized in that: it also includes gas tube 7, air bag 8, and under 2 of the catheters mediation sacculus 3 with circular hole 4 on one section for the double wall pipe of hollow, its gas tube 7 upper ends are connected with an air valve 9, its stage casing is passed in the double-layer tube wall chamber of mediation sacculus 3, lower end feeding catheter 2; On 8 catheters of its air bag, the 2 lower end circular holes 4, be enclosed within outside the catheter 2, and leave little perforation 10 around the outer tube wall of this section catheter, urethral catheterization tube wall chamber is communicated with airbag chamber.
