Film is dialysed, and this treatment means needs are frequent to carry out, and wound and dialysis tubing interface easily infect germ, and then patient is caused to send out
Inflammation adds the pain and medical expenses of patient.Traditional peritoneum dialysis catheter is that antiseptic is added in tube material or is being dialysed
Pipe surface coats antibiotic layer, but antiseptic can generate damage to human body, and is also easy to produce drug-fast bacteria；In addition, with usage time
Extension, antiseptic burst size can reduce, and antimicrobial coating can also come off, and be deteriorated so as to cause antibacterial effect.
Utility model patent peritoneum dialysis catheter (Application No. 201420605155.3) includes peritoneum dialysis catheter tube body, peritonaeum
Dialysis tubing tube body includes the outer section tube body of abdomen and abdominal cavity section tube body, and abdominal cavity section tube body is flexible, arc-shaped bend pipe, and in abdominal cavity, section is managed
The hard sleeve identical with the bending of abdominal cavity section tube body is cased at the arc of body, is set on the tube wall of the front end of abdominal cavity section tube body
Multiple dialysis holes.The utility model can prevent fibrin, clot or omentum majus fat from entering dialysis hole and causing to dialyse
Blockage, but without antibacterial structure and measure, patient easily infects germ in frequently treating, and then causes patient's inflammation, increases
Add the pain and medical expenses of patient.
Therefore be badly in need of providing it is a kind of with physical method antibacterial, to patient's fanout free region, antibacterial and good antimicrobial effect, the retention time
Long antibacterial peritoneum dialysis catheter.
Utility model content
The purpose of this utility model is the deficiency for existing peritoneum dialysis catheter, provides one kind with physical method antibacterial, right
Patient's fanout free region, antibacterial and good antimicrobial effect, the antibacterial peritoneum dialysis catheter of retention time length.
The utility model provides following technical solution：
A kind of antibacterial peritoneum dialysis catheter, the antibacterial peritoneum dialysis catheter include external catheter, the external catheter both ends point
Not She You human body connector and injection connector, the surface of the antibacterial peritoneum dialysis catheter be equipped with antibacterial microstructured layers.

One kind, dimpling block of different shapes can make the antibacterial peritoneum dialysis catheter have additional utility, such as the dimpling of circular cross section
Block can make antibacterial peritoneum dialysis catheter have hydrophobic performance.
Preferably, the antibacterial microstructured layers are arranged on the single or double of the antibacterial peritoneum dialysis catheter.
Preferably, the end of the human body connector is equipped with iodide-containing cap, and the injection connector is connected with titanium alloy connector, Iodophor
For protecting human body connector, titanium alloy connector is used to connect the components such as J-type conduit cap.
The beneficial effects of the utility model are：
(1) the utility model is equipped with antibacterial microstructured layers on the surface of antibacterial peritoneum dialysis catheter, which can
To prevent bacterium in its surface attachment, growth and migration, there is antibacterial and antibacterial effect.
(2) the antibacterial microstructured layers in the utility model, to patient's fanout free region, avoid antiseptic with physical method antibacterial
The generation of damage and drug-fast bacteria to human body.
(3) the antibacterial microstructured layers stable structure in the utility model, will not come off, therefore with the extension of usage time
The antibacterial action retention time is long.
(4) the antibacterial microstructured layers in the utility model antibacterial, it is antibacterial while there are the additional utilities such as hydrophobic.
