Abstract
The utility model pertains to the field of medical instruments and relates to a catheter. The catheter comprises a catheter body. A urine inlet of the catheter body is provided with an air bag. A urine outlet of the catheter body is connected with an air bag inflating guiding pipe communicated with an inflating pipeline; the end portion of one end, provided with the air bag, of the catheter body is provided with a lubricating liquid outlet; the end of the lubricating liquid outlet of the catheter body is connected with an oil inflating pipe communicated with the urine outlet; and a liquid storing air bag is arranged on the oil inflating pipe. The catheter has following beneficial effects: inserting resistance of inserting the catheter is reduced; damage to urethral mucosa by the catheter body is avoided; probability of infection of a urinary system is reduced; and comfortable degrees of patients are improved.
Description
Technical field
This utility model belongs to medical instruments field, is specially a kind of catheter.
Background technology
Urethral catheterization is the technical operation of commonly using clinically, the structure of catheter of the prior art comprises urethral catheterization body, one end of urethral catheterization body is provided with air bag, the other end of urethral catheterization body is urine outlet, urine outlet one end of urethral catheterization body is connected with the airbag aeration conduit being communicated with loading line, and air bag is for interior fixing.But existing catheter is inserting in the process of urethra, because do not have any lubricant method, easily the damage to mucous membrane of urethra, causes the generation of edema, infection.
Utility model content
The purpose of this utility model is to provide a kind of catheter, can, inserting in the process of catheter, constantly to urethra input lubricating fluid (containing analgesia, antiinflammatory composition), reduce the insertion resistance of catheter, avoids the damage of catheter to mucous membrane of urethra.
The technical scheme that realizes above-mentioned purpose is: a kind of catheter, comprise urethral catheterization body, one end of urethral catheterization body is urine filling mouth, the other end is urine outlet, urine filling mouth one end of urethral catheterization body is provided with air bag, in the sidewall of urethral catheterization body, be provided with the loading line being connected with air bag, urine outlet one end of urethral catheterization body is connected with the airbag aeration conduit being communicated with loading line, and the end of airbag aeration conduit is provided with charge valve; It is characterized in that: the end that described urethral catheterization body arranges air bag one end is provided with lubricating fluid outlet, in the sidewall of urethral catheterization body, be provided with lubricating fluid and export the lubricating fluid diversion pipeline being connected, urine outlet one end of described urethral catheterization body is connected with the oil filler pipe being connected with lubricating fluid diversion pipeline, on oil filler pipe, be provided with liquid storage air bag, the end of oil filler pipe is provided with prefill valve.
Further, on described urethral catheterization body, be provided with first flow control valve.
Further, on the oil filler pipe between liquid storage air bag and diversion tube, be provided with second control valve.
Further, described oil filler pipe comprises the first connection tube and the second connection tube, the first connection tube is connected with urethral catheterization body, and described liquid storage air bag and second control valve are arranged on the second connection tube, and between the first connection tube and the second connection tube, removable seal is connected.
This utility model is simple in structure, reasonable in design, easy to use; When use, in liquid storage air bag, be filled with lubricating fluid, in plugging in catheter, lubricating fluid exports outflow along lubricating fluid diversion pipeline from lubricating fluid, reduce to insert the insertion resistance of catheter, avoid the damage of catheter to mucous membrane of urethra, reduced the probability of urinary system infection, strengthened patient's comfort level.
Oil filler pipe of the present utility model comprises the first connection tube and the second connection tube, between the first connection tube and the second connection tube, removably connects, and inserts after urethra at catheter, can take off the second connection tube, improves the comfort level in use procedure.
