Detailed Description
In order to make the technical scheme of the present utility model better understood by those skilled in the art, the present utility model will be further described in detail with reference to the accompanying drawings.
Referring to fig. 1-6, a dialysis catheter for nephrology department, comprising:
a first end peritoneal dialysis tube 1 and a second end peritoneal dialysis tube 2, the first end peritoneal dialysis tube 1 being for connection to a peritoneal dialysis device, the second end peritoneal dialysis tube 2 being for insertion into the peritoneal cavity of a patient; namely, the peritoneal dialysis tube in the prior art is divided into two sections, and peritoneal dialysis tubes with different lengths are exchanged between the peritoneal dialysis tubes at the two ends so as to change the whole length of the peritoneal dialysis tube, and then the length of the peritoneal dialysis tube can be adjusted according to the needs;
the first butt joint 3 is connected with the reverse end of the connecting end of the peritoneal dialysis tube 1 and the peritoneal dialysis equipment at the first end and the reverse end of the connecting end of the peritoneal dialysis tube 2 inserted into the peritoneal cavity of the patient at the second end; wherein the first pair of connectors 3 are in communication with the corresponding first end peritoneal dialysis tube 1 and second end peritoneal dialysis tube 2;
the three-way pipe fitting 4 is connected with one end part, close to the first butt joint 3, of the first end peritoneal dialysis pipe 1, one end part, close to the first butt joint 3, of the second end peritoneal dialysis pipe 2, and one branch channel of the three-way pipe fitting 4 is connected with the first butt joint 3; that is, two branches of the three-way pipe fitting 4 are communicated with the first end peritoneal dialysis tube 1 (the second end peritoneal dialysis tube 2), and the other ends are used for arranging the first pair of joints 3;
the second butt joint 5 corresponds to the first butt joint 3 and is in butt joint communication with the first butt joint 3, and a butt joint fixing mechanism is arranged between the second butt joint 5 and the first butt joint 3;
and a replaceable short tube 6 and a replaceable long tube 7, and both ends of the replaceable short tube 6 and the replaceable long tube 7 are connected with a second butt joint 5.
Specifically, two adjacent sections of peritoneal dialysis tubes are in butt joint through the first butt joint 3 and the second butt joint 5, and are in butt joint fixation through the butt joint fixation mechanism. Through the split setting of the three-way pipe fitting 4, the replaceable short pipe 6 and the replaceable long pipe 7 can not be mutually influenced when being mutually replaced, namely, when the replaceable short pipe 6 and the replaceable long pipe 7 work normally, the replaceable short pipe 6 and the replaceable long pipe 7 can be continuously replaced, so that the using length can be flexibly adjusted.
In summary, the device sets the first butt joint 3 and the second butt joint 5 on the conventional dialysis catheter, and is in butt joint through the butt joint fixing mechanism, so as to flexibly switch the short replaceable pipe 6 with shorter connection length or the long replaceable pipe 7 with longer connection length according to the needs, and then solve the technical problem that the use length of the dialysis catheter in the prior art cannot be adjusted according to the needs.
Further, the first butt joint 3 is provided with a ball valve 8. In the process of continuously replacing the replaceable short tube 6 and the replaceable long tube 7, the ball valve 8 on the corresponding first butt joint 3 is closed at the replaced replaceable short tube 6 or replaceable long tube 7 end to prevent the passage, so that the peritoneal dialysis solution or the in-vivo metabolite forms the passage from the replaceable short tube 6 or the replaceable long tube 7 which is just connected and replaced, and the replaceable short tube 6 or the replaceable long tube 7 can be replaced without interruption and leakage.
Further, the second pair of joints 5 has external threads on the outside.
Further, the first butt joint 3 and the second butt joint 5 are butted in surface contact and kept in the surface contact state by the butted fixing mechanism. The first butt joint 3 and the second butt joint 5 are in surface contact so as to reduce gaps, so that quick butt joint can be completed, and sealing effect can be improved by arranging a sealing ring between the first butt joint 3 and the second butt joint 5.
Further, the first end peritoneal dialysis tube 1, the second end peritoneal dialysis tube 2, the replaceable short tube 6 and the replaceable long tube 7 are made of the same material.
Further, the docking fixing mechanism includes:
an external annular limiting protrusion 9 which is annularly arranged outside the first butt joint 3 and is positioned at one end of the first butt joint 3 which is in butt joint with the second butt joint 5;
and the connecting sleeve 10 is sleeved on the first butt joint 3, the outer annular limiting bulge 9 is positioned on the inner side of the connecting sleeve 10, one end of the connecting sleeve 10 is provided with the inner annular limiting bulge 11 clamped on the outer annular limiting bulge 9, and the inner side of the connecting sleeve 10 is provided with an internal thread matched with an external thread on the outer side of the second butt joint 5 in a threaded manner so that the connecting sleeve 10 is in threaded connection with the second butt joint 5.
Specifically, during the butt joint operation, the connecting sleeve 10 stretches out (or protrudes) from the end of the first butt joint 3, at this time, the outer annular limiting protrusion 9 blocks the inner annular limiting protrusion 11, so as to prevent the connecting sleeve 10 from separating from the first butt joint 3, and when the protruding connecting sleeve 10 is sleeved on the second butt joint 5 and is in butt joint fixation through threaded connection, the outer annular limiting protrusion 9 is tensioned through the inner annular limiting protrusion 11, and in combination with threaded connection, so that the end face of the second butt joint 5 is tightly attached to the end face of the first butt joint 3 for butt joint connection, and meanwhile, the sealing after butt joint and the fixation of a butt joint state are realized.
While certain exemplary embodiments of the present utility model have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that modifications may be made to the described embodiments in various different ways without departing from the spirit and scope of the utility model. Accordingly, the drawings and description are to be regarded as illustrative in nature and not as restrictive of the scope of the utility model, which is defined by the appended claims.
