Description
Technical field
The utility model relates to peritoneal dialysis catheters technical fields, and in particular to peritoneal dialysis catheters special connector.
Background technique
Peritoneal dialysis is a kind of dialysis that blood is purified using the peritonaeum of patient itself as semi-transparent film.Peritonaeum
Dialysis because having many advantages, such as to carry out at home, it is easy to operate while small to hemodynamic effect, have become more and more
The important replacement therapy method of one kind of end stage renal disease.Peritoneal dialysis access is connect by peritoneal dialysis catheters, titanium
Head and peritoneal dialysis external short tube composition, the intact of peritoneal dialysis access is one of necessary condition that peritoneal dialysis is normally carried out,
However as the extension of peritoneal dialysis time, rupture leakage occurs for peritoneal dialysis catheters caused by any reason, can lead to abdomen
The raising of film inflammation incidence, serious person possibly even need to exit peritoneal dialysis treatment.Traditional peritoneal dialysis catheters are divided into abdomen
Inner segment, hypodermic tunnel section and abdomen outer segment, be between each section it is integrated, cannot separate, it is necessary to which the abdomen inner segment of conduit is placed in abdomen
After chamber, hypodermic tunnel could be established, if rupture leakage or the set abjection of outer terylene occurs, the past processing method is whole eradicates except original
There are peritoneal dialysis catheters, reapposes new peritoneal dialysis catheters, this method wound is big, costly.
Utility model content
It is dedicated the purpose of the utility model is to overcome a kind of peritoneal dialysis catheters are provided in place of the deficiencies in the prior art
Connector.
To achieve the above object, the technical solution that the utility model is taken is as follows:
A kind of peritoneal dialysis catheters special connector, including inner wall and the catheter channel being arranged in the inner wall, institute
Stating connector is shuttle shape structure, and it is among it cylinder shape inner wall that the inner wall at the both ends of the connector, which is conical inboard wall, described
Conical inboard wall is equipped with the screw thread to match with the hypodermic tunnel section conduit of peritoneal dialysis catheters, the outer diameter of the cylinder shape inner wall
No more than the outer diameter of the hypodermic tunnel section conduit of peritoneal dialysis catheters.
If, only need to be in outside former peritoneal dialysis catheters there is a situation where tunnel infection or the set abjection of outer terylene in peritoneal dialysis
Terylene covers proximal end cutting, and the abdomen inner segment conduit, interior terylene set and part tunnel construction sections conduit, access for retaining former peritoneal dialysis catheters connect
Device is connect, separately takes an existing list CUFF peritoneal dialysis catheters to cover proximal end detachment in terylene, and discard abdomen inner segment conduit, passes through this
Single CUFF peritoneal dialysis catheters are connect to form one completely by the connector of utility model with the stump of former peritoneal dialysis catheters
Peritoneal dialysis catheters rebuild peritoneal dialysis hypodermic tunnel, set the outer terylene set of the saturating conduit of abdomen and locate away from tunnel exit 2cm, suture fixation
Outer terylene set, eradicates except original peritoneal dialysis catheters without whole, reapposes whole peritoneal dialysis catheters.Single CUFF peritonaeum
Dialysis catheter is threadedly coupled with the stump of former peritoneal dialysis catheters by connector realization, is convenient to mount and dismount, and can effectively improve
The connectivity robustness of the two, avoids the case where falling off.
Preferably, the outer diameter of the cylinder shape inner wall is equal to the outer diameter of the hypodermic tunnel section conduit of peritoneal dialysis catheters.Institute
State cylinder shape inner wall outer diameter be equal to hypodermic tunnel section conduit internal diameter, then by connector by single CUFF peritoneal dialysis catheters with
After the stump connection of former peritoneal dialysis catheters, connector can be surrounded by hypodermic tunnel section conduit completely, avoid connector
Tunnel surrounding subcutaneous tissue is impacted.
Preferably, the outer diameter of the cylinder shape inner wall is equal to the internal diameter of peritoneal dialysis catheters hypodermic tunnel section conduit.
Preferably, the material of the connector is silica gel, therefore the connector has good biocompatibility.
Preferably, the taper of the conical inboard wall is 15 °~20 °, convenient for the assembly and disassembly of connector, effectively improves the list of replacement
The connectivity robustness of the stump of CUFF peritoneal dialysis catheters and former peritoneal dialysis catheters, prevents connector from falling off, and the company of reduction
It connects in device through the influence to entire peritoneal dialysis access.
Compared with prior art, the utility model has the following beneficial effects:
The utility model of simple structure and strong practicability.If tunnel infection or the set abjection of outer terylene occur in peritoneal dialysis
The case where, it need to only be cut off in terylene set proximal end outside former peritoneal dialysis catheters, separately take an existing list CUFF peritoneal dialysis catheters,
It is covered into proximal end detachment in terylene, and discards abdomen inner segment conduit, passes through the connector and former peritoneal dialysis catheters of the utility model
Stump connect to form a complete peritoneal dialysis catheters, rebuild peritoneal dialysis hypodermic tunnel, set the outer terylene set of the saturating conduit of abdomen
At tunnel exit 2cm, the fixed outer terylene set of suture is eradicated except original peritoneal dialysis catheters without whole, is reapposed whole
Root peritoneal dialysis catheters.
Detailed description of the invention
Fig. 1 is the peritoneal dialysis catheters special connector structural schematic diagram of the utility model, in figure, 1- inner wall, and 2- conduit
Channel, 11- conical inboard wall, 12- cylinder shape inner wall.
Specific embodiment
For the purpose of this utility model, technical solution and advantage is better described, below in conjunction with specific embodiment to this
Utility model further illustrates.It will be appreciated by those skilled in the art that specific embodiment described herein is only to explain this
