Abstract
The present invention relates to a kind of free bonding PE tubing medical connector, comprise main body and at least two connecting ends for connecting pipeline, be characterised in that: described main body is shaped with shoulder on the position of connecting end, described connecting end is set with can Rule male connector of circumferential rotation, and Rule male connector realizes the axially locating with connecting end by the shoulder in main body; Rule male connector and connecting end are set with and are connected with PE in the cavity that formed and manage, and described PE pipe is by Rule negative joint inner hole wall and Rule male connector fuse outer surface fit sealing.Advantage is: not only can avoiding the PE mouth of pipe because expanding the cracking caused, ensureing the join strength in PE pipe and adapter connector portion; But also the sealability in PE pipe and adapter connector portion can be increased substantially.In addition, in Clinical practice, easily pipeline and adapter connector unclamped by Rule male connector and Rule negative joint screw thread or disconnect, smooth in gas discharge fast, and then facilitate the clinical manipulation of medical care personnel.
Description
Technical field
The invention belongs to technical field of medical instruments, particularly relate to a kind of free bonding PE tubing medical connector.
Background technique
Medical connector is usually used in connection between the medical line of a medical device and another medical line or disconnection, and can be provided by water-tight seal fully when correctly connecting and connect fast or break function.At present, the connection of the medical connector used clinically and PE pipe is generally the Placement adopting joint external diameter and tubing even surface chemical adhesive to bond.Because PE pipe is by the restriction of Clinical practice condition, the diameter of its diameter close to adapter connector can not be accomplished, therefore first PE must be managed swollen (expansion) when connecting to open and make it match with adapter connector, and then by chemical adhesive, inner tube wall is mutually bonding with adapter connector external diameter.So not only easily cause PE mouth of pipe stress cracking, the join strength in PE pipe and adapter connector portion cannot be ensured; But also the sealing in PE pipe and adapter connector portion can be had influence on.In addition, because convention connectors is bonding with pipeline, in Clinical practice, if there is bubble in pipeline, therefore pipeline and adapter connector cannot be unclamped or disconnect, and can not smoothly gas be discharged, and then bring inconvenience to medical care personnel.
Summary of the invention
The present invention for solve in known technology the technical problem that exists and provide a kind of structure simple, increase substantially connection sealing energy and be convenient to the free bonding PE tubing medical connector of clinical dismounting.
The technological scheme that the present invention takes for the technical problem existed in solution known technology is:
Free bonding PE tubing medical connector, comprise main body and at least two connecting ends for connecting pipeline, described main body is shaped with shoulder on the position of connecting end, described connecting end is set with can Rule male connector of circumferential rotation, and described Rule male connector realizes the axially locating with connecting end by the shoulder in main body;
Described Rule male connector and described connecting end are set with and are connected with PE in the cavity that formed and manage, and described PE pipe is by Rule negative joint inner hole wall and Rule male connector fuse outer surface fit sealing.
The present invention can also adopt following technological scheme:
The connecting end outer wall of described suit Rule male connector is also shaped with for installing Rule male connector and the annular relief for its axially locating.
The rectangular triangle in cross section of described annular relief.
The advantage that the present invention has and good effect are: because the present invention adopts technique scheme, namely by Rule male connector and Rule negative joint PE managed on traditional connector and be fastenedly connected sealing with adapter connector, so not only can avoiding the PE mouth of pipe because expanding the cracking caused, ensure that the join strength in PE pipe and adapter connector portion; But also the sealability in PE pipe and adapter connector portion can be increased substantially.In addition, in Clinical practice, pipeline and connector can unclamp or disconnect by screw thread by Rule male connector and Rule negative joint easily, smooth in gas discharge fast, and then facilitate the clinical manipulation of medical care personnel.
