[0024] Example 1
[0025] Disposable sterile interface closure device, such as Figs. 1-3 As shown, it includes a first plastic sleeve 1, a connecting plastic sheet 12 fixed to the outer wall of the first plastic sleeve 1, a second plastic sleeve 6 fixed to the outer wall of the connecting plastic sheet 12, thin sponge filling cavities 10 respectively provided on the inner walls of the first plastic sleeve 1 and the second plastic sleeve 6, a card plate 2 fixed to the outer wall of the first plastic sleeve 1, a set of buckles 5 fixed to the outer wall of the second plastic sleeve 6, a set of slots 9 opened on the outer wall of the card plate 2, and the buckles 5 snapping into the inner wall of the slots 9;
[0026] Limiting rings 11 are fixed to the inner walls of the second plastic sleeve 6 and the first plastic sleeve 1, respectively;
[0027] The inner wall of the thin sponge filling cavity 10 is provided with a matching thin sponge;
[0028] The first plastic sleeve 1 and the second plastic sleeve 6 are fitted onto the external short pipe 7, and one end of the external short pipe 7 is provided with an external short pipe threaded port 8.
[0029] The first plastic jacket 1 and the second plastic jacket 6 are fitted onto the peritoneal dialysis fluid tubing connector 4, and the peritoneal dialysis fluid tubing connector 4 and the external short pipe threaded port 8 are connected by threads.
[0030] One end of the peritoneal dialysis tubing connector 4 is connected to the peritoneal dialysis tubing 3.
[0031] The disposable sterile interface closure device consists of a first plastic jacket 1 and a second plastic jacket 6 connected together by a connecting plastic sheet 12. The thin sponge filling cavity 10 of the first plastic jacket 1 and the second plastic jacket 6 is filled with a thin sponge. Each disposable sterile interface closure device is sterilized by ethylene oxide.
[0032] When a patient needs peritoneal dialysis, first unscrew the iodine cap at the threaded port 8 of the external short tube. Then connect the threaded port 8 of the external short tube to the peritoneal dialysis fluid connector 4 via the thread. Next, put the first plastic clip 1 and the second plastic clip 6 on the connection between the threaded port 8 of the external short tube and the peritoneal dialysis fluid connector 4. Then, insert the buckle 5 into the slot 9 on the outer wall of the clip plate 2 to fasten the first plastic clip 1 and the second plastic clip 6 together, thereby covering and sealing the connection between the threaded port 8 of the external short tube and the peritoneal dialysis fluid connector 4, keeping the connection aseptic to avoid patient contamination.
[0033] After the patient completes peritoneal dialysis, the disposable sterile interface closure device can be removed and discarded from the connection between the external short pipe thread port 8 and the peritoneal dialysis fluid line connector 4. A new disposable sterile interface closure device should be used for each peritoneal dialysis session.
[0034] The connecting plastic sheet 12 can connect the first plastic sleeve 1 and the second plastic sleeve 6. Since the connecting plastic sheet 12 is thin and its material has a certain degree of ductility, the user can bend the connecting plastic sheet 12 to hold the first plastic sleeve 1 and the second plastic sleeve 6 together. Since the closure is for single use, there is no need to bend the connecting plastic sheet 12 back and forth. Therefore, when the connecting plastic sheet 12 is bent only once, it will not break due to its material ductility, thus stably connecting and fixing the first plastic sleeve 1 and the second plastic sleeve 6.
[0035] The limiting ring 11 located on the inner wall of the first plastic jacket 1 and the second plastic jacket 6 can limit the threaded port 8 of the external short pipe inserted into the inner wall of the peritoneal dialysis tubing connector 4, thereby improving the tightness of the inner walls of the first plastic jacket 1 and the second plastic jacket 6 on the peritoneal dialysis tubing connector 4 and the outer wall of the external short pipe threaded port 8.
[0036] Working principle: When a patient needs peritoneal dialysis, first unscrew the iodine cap at the threaded port 8 of the external short tube. Then connect the threaded port 8 of the external short tube to the peritoneal dialysis fluid connector 4 through the thread. Next, put the first plastic clip 1 and the second plastic clip 6 on the connection between the threaded port 8 of the external short tube and the peritoneal dialysis fluid connector 4. Then, snap the buckle 5 into the slot 9 on the outer wall of the clip plate 2 to fasten the first plastic clip 1 and the second plastic clip 6 together, thereby covering and sealing the connection between the threaded port 8 of the external short tube and the peritoneal dialysis fluid connector 4, keeping the connection in a sterile state to avoid patient contamination.
[0037] After the patient completes peritoneal dialysis, the disposable sterile interface closure device can be removed and discarded from the connection between the external short pipe thread port 8 and the peritoneal dialysis fluid line connector 4. A new disposable sterile interface closure device should be used for each peritoneal dialysis session.
