Abstract

The utility model discloses an antiseep catheter belonging to an appliance for diverting human body media or taking out media from human body, in particular to a catheter. The antiseep catheter is characterized in that the end part of the catheter is provided with a tie-in with inner threads. As the tie-in with inner threads, which consists of an outer sleeve with inner threads and a cone-shape inner pipe in the centre is arranged at the end of the catheter, the catheter can fit the tie-in with outer threads arranged at an urine collecting bag to make the tie-in of the urine collecting bag firmly connected with the tie-in of the catheter, and the drained urine is kept and is guaranteed not to leak; as the surface of the catheter is provided with a length scale with the front end as the starting point, the inserting depth can be easily and accurately observed when the catheter is inserted into human body, which well overcomes the defect that the inserting depth of the prior catheter can only be determined by the experience of the doctor.

Description

Anti-infiltration catheter

Technical field

This utility model belongs to for the transfering human medium or for take out the apparatus, particularly catheter of medium in human body.

Background technology

Need usually use catheter for disease treatment and carry out urethral catheterization, clinical normal employing latex balloon catheter (Foley catheter) and disposable plastic catheter.The urinary catheter insertion depth, the male enters 15-20cm approximately, and the women enters 6-8cm approximately, and urine can flow out, and inserts 2cm again after seeing urine.If need indwelling catheter, after fixing, for collecting the cone-shaped plug insertion catheter end that urine normally will link to each other with aseptic urine drainage bag.Owing to do not have scale on the catheter, only can estimate to insert the degree of depth of urethra, as insert deeply, may make the bladder discomfort, cause urinary tract infection easily as plug repeatedly; Catheter is terminal in addition occurs fixing not firm or slippage causes urine leakage to bedding easily with being connected near cone-shaped plug of aseptic urine drainage bag.

The utility model content

The purpose of this utility model provides a kind of catheter end and firmly is connected with urine drainage bag, can show the technical scheme of the novel catheter of catheter insertion depth.

The technical solution of the utility model is that a kind of anti-infiltration catheter is characterized in that: the joint that the band internal coiling is housed at the end of catheter.

The joint of described band internal coiling is made up of with the taper inner core tube that is positioned at the center the overcoat of band internal coiling.

It is the length graduation mark of starting point that the appearance of described catheter has from front end.

Because the joint of the band internal coiling of being made up of the overcoat of being with internal coiling and the inner core tube that is positioned at the taper at center has been installed at the end of catheter, can cooperate with the joint of band external spiral on the urine drainage bag closely is connected on the catheter joint urine drainage bag joint, retention catheterization also can guarantee non-leakage, because it is the length scale of starting point that the appearance of catheter has from front end, when inserting human body, can make things convenient for the insertion depth of observing exactly at any time, well solve existing catheter is only determined insertion depth with doctor's experience shortcoming.
