Abstract
The utility model relates to a urine catheter. The external diameter can be expanded. The utility model is characterized in that the external diameter of the catheter can be controlled by the controlling of the flow rate of the fluid entering into the catheter balloon; when the catheter is inserted into or taken out of the urethra, the external diameter of the catheter is shortened for convenience; when the catheter is inserted into human body, the external diameter of the catheter is enlarged, which is convenient for the fixation of the catheter and the expansion of the urethra; thus, the handling difficulties and steps of medical staff are reduced; the utility model also relieves the suffering of patient in the application of the catheter. The utility model has an advantage that the utility model can also be used to expand and measure the urethra and achieve urethral bleeding.
Description
Technical field:
This utility model is the expansible catheter of a kind of medical external diameter.
Background technology:
The employed catheter of hospital is made with latex or silica gel tube usually at present, because the external diameter of catheter can not change, the too little meeting of doing during design causes managing outer wall and urethra forms the gap, causes urine to omit; If external diameter and urethra inwall sizableness cause patient's misery when inserting again; Especially to the patient of urethral stricture or obstruction, medical personnel's operation is also difficult.
The utility model content:
This utility model is the expansible catheter of a kind of external diameter, its principal character is that catheter is outer through variable, thereby when reduced outside diameter, be convenient to catheter and insert or take out patient's urethra, when expanded outer diameter, be convenient to catheter and fixedly draw urine, and have dilating urethra, urethrometry, urethra hemostasis, the favourable effect of urinating and curing the disease concurrently endo-urethral.
This utility model, be to increase one deck composite material film at present known catheter outer wall, space between the composite material film of catheter outer wall and increase is linked to each other with inducing QI (liquid) pipe (2), form catheter gas (liquid) capsule (1), gas (liquid) pressure by control inducing QI (liquid) pipe (2) controls air inlet (liquid) amount, thus control catheter external diameter.When catheter was inserted or take out, exhaust (liquid) capsule (1) formed Fig. 2 state; When fixedly catheter or urethral dilatation,,, thereby reach the purpose of expansion catheter external diameter as Fig. 1 state to gas (liquid) capsule (1) inflation (liquid).This utility model work process is: under Fig. 2 state, bladder gas (liquid) capsule (5) and catheter gas (liquid) capsule (1) are close to catheter, the catheter external diameter is little, after inserting patient's urethra, inflate (liquid) by bladder air inlet (liquid) mouthful (6) to bladder gas (liquid) capsule, at this moment, bladder air sac expands, catheter is fixed on patient's urethra, then by inducing QI (liquid) pipe (2), to catheter gas (liquid) capsule (1) inflation (liquid), catheter expands into the shape as Fig. 1, and urine is urinated to outlet (4) by the eye (3) of urinating.This catheter can be joined relief valve, can shrink automatically during emergency.Urethral catheterization rate of expansion and big or small whole process can be controlled by medical worker and patient, and is safe and reliable.
Description of drawings:
Fig. 1 is a catheter expansion state profile; Fig. 2 inserts for catheter or when taking out human body and the non-working condition profile.
The specific embodiment:
Make with composite high-molecular material.
Claims (3)
1. expansible catheter of external diameter, it is characterized in that increasing gas/liquid capsule (1) on the catheter outer wall at present, control the catheter external diameter by leading gas/liquid pipe (2) control turnover gas/liquid amount, reduced outside diameter when patient's urethra is inserted or taken out to catheter, in catheter is fixed on the patient body or when needing urethral dilatation, expanded outer diameter.
2. the expansible catheter of external diameter according to claim 1 is characterized in that an end of leading gas/liquid pipe (2) links to each other with gas/liquid capsule (1), and the defeated gas/liquid device of the other end and may command pressure joins.
3. the expansible catheter of external diameter according to claim 1, it is characterized in that gas/liquid capsule (1) is not when filling gas/liquid, tightly be attached to the catheter outer wall, in the capsule with lead gas/liquid pipe (2) and link to each other, gas/liquid capsule (1) can evenly be expanded when filling gas/liquid, thereby make the catheter external diameter expansion, user can be controlled the catheter external diameter according to handling gas transmission/liquid measure.
