Description
Technical field
This utility model belongs to field of medical technology, is specifically related to a kind of negative pressure catheter.
Background technology
Clinical indwelling catheter nursing technique complication---CAUTI is the most common hospital infection except respiratory tract infection.In the U.S., CAUTI accounts for 30.0 ~ 40.0% of hospital infection, and wherein 80% causes because of indwelling catheter, and China's incidence rate is close with it.CAUTI makes patient's hospital day on average extend 1.59, also can cause bacteremia and septicemia, makes mortality rate add 15%.Antibacterial is by entering the urinary tract system of patients with catheterization with intracavity two approach outside chamber, outside being respectively (1) chamber, approach comprises: the antibacterial being 1. positioned at patient's perineal position is directly settled down in catheter proximal end catheter inserting is fashionable, or per urethram goes upward to the nearly section surface of conduit around mouth; 2. indwelling catheter forms loose mucous sheath between contributing between conduit and mucous membrane of urethra, and antibacterial to be moved ahead intrusion bladder along catheter surface by mucous sheath.(2) intracavitary route: refer to that microorganism goes upward to bladder along conduit cavity.At present, mainly reach by adopting disinfectant solution to carry out perineum cleaning the object that control chamber infects outward, and intracavitary route is uncontrollable.
Bacterial biofilms (Biofilm, BF) is a key character of urinary tract infection.BF is adsorbed in surface of solids microbial flora by relying on extracellular products is formed, and in conjunction with organic and inorganic constituents, can be formed and comprise complicated physical and chemical processes and biocenological interaction.BF is difficult to come off after adhering to catheter lumens, and at present clinically mainly through using antibiosis usually to reduce the formation of BF, but mostly be Resistant strain due to the antibacterial forming BF, effect is not satisfactory.Therefore, the formation how eliminating BF will be the clinical difficult problem that need solve.
Utility model content
The purpose of this utility model is solve the problems of the technologies described above and provide a kind of negative pressure catheter.
For achieving the above object, this utility model adopts according to following technical scheme:
A kind of negative pressure catheter, comprise drainage tube, one end of described drainage tube is arranged in human body, and urine is discharged by evacuating catheter by the other end of described drainage tube, one end being provided with evacuating catheter (2) of described drainage tube is also linked with negative-pressure suction pipe, and described negative-pressure suction pipe produces negative pressure cleaning be adsorbed on impurity on drainage tube tube wall for connecting vacuum extractor, valve and lower valve is also provided with in described drainage tube, described upper valve and lower valve are movably connected on the tube wall of drainage tube, described upper valve is provided with oblique slot away from the one end with drainage tube tube wall junction, described lower valve is provided with oblique falcon away from the one end with drainage tube tube wall junction, the one end described upper valve being provided with oblique slot is also provided with Magnetitum, the one end described lower valve being provided with oblique falcon is also provided with Magnetitum, the Magnetitum polarity that described upper valve and lower valve are installed is contrary, described upper valve and lower valve are connected with stay cord for controlling both actions.
Preferred as one, described upper valve and lower valve are respectively connected with spring, and one end of described spring is connected with upper valve and lower valve, and the other end is connected on the tube wall of drainage tube.
Preferred as one, described spring is stage clip.
Preferred as one, one end being linked with negative-pressure suction pipe of described drainage tube is provided with seal cover, and described evacuating catheter and negative-pressure suction pipe are arranged on seal cover.
Preferred as one, described seal cover is also provided with gas tube and syringe pipe.
This utility model is by negative-pressure suction pipe UNICOM negative pressure suction device, dirt removal in drainage tube tube wall can be fallen, simultaneously upper and lower valve structure be arranged so that when vacuum suction works, the outside flow direction of drainage tube is closed, and avoids the loss of cleaning operation to human body.
