Abstract

The invention relates to a bonding-free PE tube medical connecting device. The bonding-free PE tube medical connecting device comprises a body and at least two connecting ends used for connecting pipelines, and is characterized in that a lift shoulder is manufactured in a position, close to one connecting end, of the body, a Luer male connector capable of rotating in the circumferential direction is installed on the connecting end in a sleeved mode, the Luer male connector and the connecting end achieve axial positioning through the lift shoulder on the body, a PE tube is connected in a cavity formed by the Luer male connector and the connecting end in a sleeved mode, and the PE tube is tightly sealed with the outer surface of a core of the Luer male connector through the wall of an inner hole of a Luer female connector. The bonding-free PE tube medical connecting device has the advantages of avoiding cracks of the opening of the PE tube caused by expansion, guaranteeing the connecting intensity of the PE tube and the connector of the connecting device, and largely improving the sealing performance of the PE tube and the connector of the connecting device. Besides, in the clinical use, the pipelines and the connector of the connecting device can be loosened or disconnected conveniently through the thread of the Luer male connector and the thread of the Luer female connector, gas is discharged rapidly and smoothly, and further convenience is brought to the clinical operation for medical staff.

Description

Free bonding PE tubing medical connector
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
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 provide by water-tight seal fully and connect fast or break function.At present, the medical connector that uses clinically generally is 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 subjected to the restriction of clinical service condition, can not accomplish that its diameter is near the diameter of adapter connector, therefore when connecting, must earlier PE pipe bloated (expansion) be opened it is matched with adapter connector, and then by chemical adhesive that inner tube wall is mutually bonding with the adapter connector external diameter.So not only cause PE mouth of pipe stress cracking easily, can't guarantee the join strength of PE pipe and adapter connector portion; PE manages and the sealing of adapter connector portion but also can have influence on.In addition, because traditional connector and pipeline are bonding, in clinical use, if occur bubble in the pipeline, thus pipeline and adapter connector can't 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 the technical problem that exists in the known technology provide a kind of simple in structure, increase substantially the free bonding PE tubing medical connector that connects sealability and be convenient to clinical dismounting.
The technological scheme that the present invention takes for the technical problem that exists in the solution known technology is:
Free bonding PE tubing medical connector, comprise main body and at least two connecting ends that are used for connecting pipeline, described main body is shaped on half the circumference of the sleeve where it joins the shoulder near on the position of connecting end, be set with on described this connecting end can circumferential rotation Rule male connector, described Rule male connector is realized axially locating with connecting end by the half the circumference of the sleeve where it joins the shoulder on the 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 present invention can also adopt following technological scheme:
Also be shaped on the connecting end outer wall of described suit Rule male connector for Rule male connector being installed and being used for the annular relief of its axially locating.
The rectangular triangle in the cross section of described annular relief.
Advantage and good effect that the present invention has are: because the present invention adopts technique scheme, namely on traditional connector, by Rule male connector and Rule negative joint the PE pipe is fastenedly connected sealing with adapter 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 portion; PE manages and the sealability of adapter connector portion but also can increase substantially.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 make things convenient for medical care personnel's clinical manipulation.
