The specific embodiment
With reference to accompanying drawing, a kind of visual peritoneal dialysis catheter described in the utility model, comprise seal wire bar 1, the head of described seal wire bar is photographic head 2, in the middle of described seal wire bar, be provided with handle 4, be blocked in visual peritoneal dialysis pipe joint and handle is connected with visual peritoneal dialysis pipe joint when being connected with visual peritoneal dialysis catheter.The afterbody of described seal wire bar is the data union joint 3 of USB joint or other shapes, connects computer or dedicated display during for needs.
The head of described peritoneal dialysis catheter seal wire bar is photographic head, and described photographic head is fibre-optical probe or ccd sensor, and the illuminator of photographic head is built-in LED lamp.Wait in use, the USB joint of afterbody or the data union joint of other shapes, be connected to computer or special-purpose display.Open built-in illuminator lamp, coordinate to observe situation shown in display screen, instruct operator can be simply, rapidly, safely peritoneal dialysis catheter is placed in abdominal cavity rectovesical ponch the direct-view in the situation that.
The head of described visual peritoneal dialysis catheter seal wire bar is photographic head, scribbles hydrophilic coating on photographic head, and further, handle also scribbles hydrophilic coating to the seal wire bar between photographic head.After peritoneal dialysis catheter placement finishes, only need inject a small amount of normal saline or sterile water for injection to peritoneal dialysis tube chamber, can activate hydrophilic coating, increase lubricity, simply and easily the peritoneal dialysis catheter seal wire with photographic head is extracted.
In Fig. 4, drawing reference numeral be 5 for peritoneal dialysis catheter, the peritoneal dialysis catheter front end band adopting in the present embodiment is just like the various irregular circular arc projection with fur shown in drawing reference numeral 7, and to reduce pipe drift and to increase dialysis surface area, the circulation of order dialysis medicinal liquid is smooth and easy.The novel band photographic head peritoneal dialysis catheter seal wire providing of this use can be applied to various peritoneal dialysis catheters.
In Fig. 6, what drawing reference numeral was 6 is elastic strip, is positioned at peritoneal dialysis catheter near skin place, to assist fixedly peritoneal dialysis catheter.When reality is used, after peritoneal dialysis catheter is placed complete and seal wire bar and withdrawn from, elastic strip is stretched and becomes 90 degree with body, utilize medical proof fabric to stick on skin, with fixing peritoneal dialysis catheter, heavily fixing as first.
