Abstract
The present invention relates to a catheter and discloses an anti-seep catheter, which comprises a canula the head part of which is provided with an urine inlet, the tail part of the canula is provided with an urine outlet, and the head part of the canula is also provided with a bladder fixing air chamber which is connected with a charging connector by an inflation tube, wherein, the canula is also sheathed with an urine absorbing bag which comprises an outer waterproof layer, an outer water-seeping layer and a middle water-absorbing layer, wherein, the outer waterproof layer is far from the canula, the outer water-seeping layer is close to the canula; the middle water-absorbing layer is placed between the outer waterproof layer and the outer water-seeping layer; the position of the urine absorbing bag at the canula can be adjusted. The catheter of the present invention can effectively prevent the urine seepage.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, relate to a kind of catheter specifically.
Background technology
Catheter commonly used clinically at present is a two-chamber monosaccate silicone catheter, at its head into urine hole is arranged, and afterbody has the mouth of urinating.During the above-mentioned catheter of clinical use, especially gerontal patient's urethral orifice is lax to find some patient, thereby urine leakage easily takes place, and not only brings very big trouble to nursery work, and has influenced patient's quality of life.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of catheter that effectively prevents urine leakage.
The present invention has adopted following technical proposals to solve above-mentioned technical problem:
A kind of anti-infiltration catheter, comprise conduit, catheter head is provided with into urine hole, afterbody is provided with the mouth of urinating, catheter head also has the bladder fixation balloon, and the bladder fixation balloon is connected with charging connector through gas tube, wherein, also be with the urine absorption bag on the conduit, the urine absorption bag comprises outside watertight composition, outside permeable layer and middle water absorbing layer, wherein, outside watertight composition is away from conduit, be waterproof material, outside permeable layer is pressed close to conduit, is seepage material, and the intermediate absorption layer is positioned in the middle of outside watertight composition and the outside permeable layer, include absorbent material, the urine absorption bag is adjustable in supravasal position.
Preferable, above-mentioned urine absorption bag in a tubular form, the external diameter difference is no more than 1 centimetre in the mouth of pipe, length is no more than 5 centimetres.
Preferable, waterproof material, seepage material and absorbent material on the above-mentioned urine absorption bag are softish material.Better, absorbent material is for forming the polymers capable of swelling of hydrogel.
Preferably, above-mentioned urine absorption bag is detachable.
When using device of the present invention, insert good catheter earlier routinely, then with the position adjustments of urine absorption bag to being close to urethral orifice, for the lax patient of urethral orifice, because the tension force effect of liquid, urine can flow out along conduit, and the absorbent material that effusive urine just in time is placed in supravasal urine absorption bag internal layer absorbs, ooze out by the urine absorption bag and outer field waterproof material can further prevent urine, thereby prevented urine leakage effectively.
