Abstract

The utility model relates to a medical drainage pipe joint, which comprises a valve. An inlet pipe and an outlet pipe of the valve are provided with joints. The joints are conical pipes, wherein, the diameters of the joints are gradually increased from 3 millimeters to 10 millimeters from interior to exterior. The outer ends of the joints are provided with circular pipes with diameters of 3 millimeters. A handle is arranged on the upper end of a valve core of the valve, and the middle part of the handle is provided with a through hole. A switch mark is arranged on the handle on the upper end of the valve core. Due to the fact that the medical drainage pipe joint is provided with the valve, the joints of conical pipes, the middle part of the handle is provided with the through hole, the medical drainage pipe joint has convenient use and good stability, and the medical drainage pipe joint can be freely closed and adjusted.

Description

A kind of drainage tube joint

This utility model relates to a kind of medical drainage tube joint.

At present, in curative activity, be used for the various drains of different treatment objectives such as closed drainage of pleural cavity, intraperitoneal drainage, biliary drainage etc., very general in clinical practice, and in the body of using for above-mentioned drain between built-in drainage tube, external external drainage tube and the liquid containing bottle, use a kind of glass or adapter of plastic at present, this joint is not only moulding to differ, and specification varies in size, be difficult to coupling, when causing clinical use, fixing inconvenience, poor stability, and drainage tube is closed adjusting and is also needed the special adjustable clamp that adds, and uses inconvenience.

The purpose of this utility model just provides a kind of easy to use, and good stability can be closed the drainage tube joint of adjusting.

To achieve these goals, the technical solution of the utility model is: a kind of drainage tube joint, its construction features is: comprise valve, the inlet tube and the outlet of valve are provided with joint, described joint serve as reasons outer to 3 millimeters of interior diameters gradually increase be 10 millimeters conical pipe, it is 3 millimeters pipe that the joint outer end has diameter; Spool upper end at valve is provided with handle, and the handle middle part has through hole.

The handle of described spool upper end is provided with the switch sign.

This utility model is owing to adopt said structure, and it comprises valve, and the inlet tube and the outlet of valve are provided with joint, described joint serve as reasons outer to 3 millimeters of interior diameters gradually increase be 10 millimeters conical pipe, it is 3 millimeters pipe that the joint outer end has diameter; The internal diameter model of built-in drainage tube and external external drainage tube is identical or different in the body, as long as internal diameter is in 3-10 millimeter scope, all can realize disposable tight connection, owing to have valve, can free adjustment and close, be convenient to change external external drainage tube, perhaps take off external external drainage tube and liquid containing bottle, make things convenient for patient activity; Spool upper end at valve is provided with handle, the handle middle part has through hole, the handle of described spool upper end is provided with the switch sign, can directly indicate the switch of valve on the one hand, the handle middle part has through hole on the other hand, be convenient to the fixing of drainage tube, played good prevent tractive, slippage effect.

Describe this utility model in detail below in conjunction with drawings and Examples;

Accompanying drawing shows the main cutaway view of this utility model embodiment;

This utility model comprises valve 2, and the inlet tube of valve 2 and outlet are provided with joint 1, described joint 1 serve as reasons outer to 3 millimeters of interior diameters gradually increase be 10 millimeters conical pipe, it is 3 millimeters pipe that joint 1 outer end has diameter; Spool 3 upper ends at valve 2 are provided with handle 4, and handle 4 middle parts have through hole 5; The handle 4 of described spool 3 upper ends is provided with the switch sign; When clinical practice, at first valve-off 2, with the taper joint 1 that built-in drainage tube in the body inserts inlet tube, the taper joint 1 that external external drainage tube is inserted outlet again, open valve 2, the through hole 5 that passes handle 4 middle parts with adhesive plaster or cotton rope is fixed in the appropriate location with drainage tube then.When temporarily need not external drainage tube, valve-off 2 takes off external external drainage tube.
