Abstract
The utility model relates to an adhesive-bonding-free PE pipe medical connector which comprises a body and at least two connecting ends used for connecting pipelines. The adhesive-bonding-free PE pipe medical connector is characterized in that the part, close to the connecting ends, of the body is provided with a lifting shoulder, the connecting ends are sleeved with male Luer tapers which are capable of rotating in the circumferential direction, and the male Luer tapers achieve axial positioning with the connecting ends through the lifting shoulder on the body; PE pipes are connected to the interior of cavities formed by installing the male Luer tapers and the connecting ends in a sleeved mode, and the PE pipes and the outer surfaces of cores of the male Luer tapers are fastened and sealed through the inner hole walls of female Luer tapers. The adhesive-bonding-free PE pipe medical connector has the advantages that cracking, of the ports of the PE pipes, caused by expansion is avoided, and the connection strength of the joint parts between the PE pipes and the tapers is guaranteed; besides, the sealing performance of the joint parts between the PE pipes and the tapers is greatly improved. Furthermore, when the adhesive-bonding-free PE pipe medical connector is in clinical use, the joint parts between the pipelines and tapers can be conveniently loosened or disconnected through the connection threads between the male Luer tapers and the female Luer tapers to discharge gas quickly and smoothly, and therefore convenience is brought to the clinical operation of medical workers.
Description
Technical field
The utility model belongs to technical field of medical instruments, particularly relates to a kind of free bonding PE tubing medical connector.
Background technique
Being connected or disconnection between the medical pipeline that medical connector is usually used in a medical device and another medical pipeline, and can be when correctly connecting by water-tight seal fully, provide and connect fast or break function.At present, the medical connector used clinically is generally the Placement that adopts joint external diameter and tubing even surface chemical adhesive bonding with being connected of PE pipe.Because the PE pipe is subject to the restriction of clinical service condition, can not accomplish that its diameter approaches the diameter of adapter connector, therefore must first PE be managed to swollen (expansion) and open it is matched with adapter connector when connecting, and then by chemical adhesive, that inner tube wall is mutually bonding with the adapter connector external diameter.So not only easily cause PE mouth of pipe stress cracking, can't guarantee the join strength of PE pipe and adapter connector section; But also can have influence on, PE manages and the sealing of adapter connector section.In addition, due to traditional connector and pipeline bonding, in clinical use, if occur bubble in pipeline, therefore pipeline and adapter connector can't be unclamped or disconnect, and can not be smoothly gas be discharged, and then brings inconvenience to medical care personnel.
The model utility content
The utility model for solve the technical problem existed in known technology provide a kind of simple in structure, increase substantially the connection sealing energy and be convenient to the free bonding PE tubing medical connector of clinical dismounting.
The technological scheme that the utility model is taked for the technical problem existed in the 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 half the circumference of the sleeve where it joins the shoulder near on the position of connecting end, on described this connecting end, be set with can circumferential rotation Rule male connector, described Rule male connector is realized the axially locating with this connecting end by the half the circumference of the sleeve where it joins the shoulder on main body;
Be connected with the PE pipe in the cavity that described Rule male connector and described connecting end suit form, described PE pipe is by Rule negative joint inner hole wall and Rule male connector fuse outer surface fit sealing.
The utility model can also adopt following technological scheme:
On the connecting end outer wall of described suit Rule male connector, also be shaped with for Rule male connector being installed and for the annular relief of Rule male connector axially locating.
The rectangular triangle in the cross section of described annular relief.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, by Rule male connector and Rule negative joint, the PE pipe is fastenedly connected to sealing with adapter connector on traditional connector, so not only can avoid the PE mouth of pipe because of the cracking that expansion causes, guarantee the join strength of PE pipe with adapter connector section; But also can increase substantially, PE manages and the sealability of adapter connector section.In addition, in clinical use, can easily pipeline and connector be unclamped or disconnect by the screw thread of Rule male connector and Rule negative joint, smoothly gas be discharged fast, and then facilitate medical care personnel's clinical manipulation.
The accompanying drawing explanation
Fig. 1 is the utility model embodiment 1 structural representation;
Fig. 2 is the utility model embodiment 2 structural representation.
In figure: 1, main body; 1-1, half the circumference of the sleeve where it joins the shoulder; 2, connecting end; 2-1, annular relief; 3, Rule male connector; 4, PE pipe; 5, Rule negative joint; 6, Rule male connector fuse.
Embodiment
For further understanding model utility content of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Be connected with PE pipe 4 in the cavity that described Rule male connector and connecting end suit form, described PE pipe completes the connecting end connection fit sealing of medical connector by the internal thread of Rule negative joint 5 inner hole walls, Rule male connector fuse 6 outer surfaces and Rule male connector 3.In the present embodiment, be shaped with on the male connector of described Rule and meet GB 6% circular cone fuse and internal thread, negative joint one end, described Rule is shaped with the outside thread matched with Rule male connector internal thread, Rule negative joint endoporus is shaped with 6% tapering, described PE pipe box is contained between Rule male connector fuse and Rule negative joint inner hole wall of medical connector, then realizes fit sealing by Rule male connector internal thread and Rule negative joint outside thread.
Be connected with PE pipe 4 in the cavity that described Rule male connector and connecting end suit form, described PE pipe is realized and medical connector connecting end fit sealing by the internal thread of Rule negative joint 5 inner hole walls, Rule male connector fuse 6 outer surfaces and Rule male connector 3.In the present embodiment, be shaped with 6% tapering fuse and internal thread on the male connector of described Rule, negative joint one end, described Rule is shaped with the outside thread matched with Rule male connector internal thread, and Rule negative joint endoporus is shaped with the circular cone of 6% tapering.Described PE pipe box is contained between Rule male connector fuse and Rule negative joint inner hole wall of medical connector, then realizes being connected and fit sealing with the outside thread of Rule negative joint by Rule male connector internal thread.
