Abstract
The utility model provides a kind of adjustable flow velocity connecting tube, including conduit, X connectors, Y-shaped connector and flow regulator, and the both ends of the conduit are separately connected the X connectors and the Y-shaped connector, and the flow regulator is set on conduit；The X connectors include cylindrical internal thread interconnecting piece, center guide portion and outer end guide portion, the center guide portion is connected to the center of cylindrical internal thread interconnecting piece, the outer end guide portion is connected to the outer end of cylindrical internal thread interconnecting piece, and is connected with the center guide portion；The Y-shaped connector is the big hollow-cone body in the small inner end in outer end, and the inner surface of hollow-cone body is equipped with internal thread.The adjustable flow velocity connecting tube of the utility model can be directly connected to central venous catheter and drainage bag, facilitate clinical manipulation, and can effectively avoid uncomfortable caused by flow velocity is too fast or excess.
Description
【Technical field】
The utility model is related to a kind of medical treatment and nursing instrument, more particularly to a kind of adjustable flow velocity connecting tube.
【Background technology】
Cancer patient late period is often accompanied by a large amount of hydrothorax, ascites, or even hydropericardium occurs.Clinically use central vein
Conduit connects the drainage that drainage bag carries out hydrothorax, ascites.But since clinically used drainage pack adapter is the long taper of screw thread,
It is incompatible with central venous catheter adapter, it can not be connected directly, operate very cumbersome, increase clinical position amount.Drawing
, may be too fast or excessive because of flow velocity during flowing liquid, cause patient uncomfortable.
【Utility model content】
The technical problems to be solved in the utility model is to provide a kind of adjustable flow velocity connecting tube, in capable of being directly connected to
The connecting tube of cardiac vein conduit and drainage bag facilitates clinical manipulation, and can effectively avoid caused by flow velocity is too fast or excess not
It is suitable.
The utility model is realized in this way：A kind of adjustable flow velocity connecting tube, including conduit, X connectors, Y-shaped connector and stream
The both ends of fast adjuster, the conduit are separately connected the X connectors and the Y-shaped connector, and the flow regulator is set in conduit
On；
The X connectors include cylindrical internal thread interconnecting piece, center guide portion and outer end guide portion, the center guide portion
It is connected to the center of cylindrical internal thread interconnecting piece, the outer end guide portion is connected to the outer end of cylindrical internal thread interconnecting piece,
And it is connected with the center guide portion；
The Y-shaped connector is the big hollow-cone body in the small inner end in outer end, and the inner surface of hollow-cone body is equipped with internal thread.
Further, the conduit, X connectors, Y-shaped connector are integrally formed by transparent TPE.
The utility model has the advantage of：The X connectors of the adjustable flow velocity connecting tube of the utility model have cylindrical internal thread
Interconnecting piece, center guide portion and outer end guide portion, can be directly connected to central venous catheter, and Y-shaped connector is that the small inner end in outer end is big
Hollow-cone body, and the inner surface of hollow-cone body be equipped with internal thread, can with directly with the taper connection pipe phase on drainage bag
Connection, facilitates clinical manipulation, and can effectively avoid uncomfortable caused by flow velocity is too fast or excess.
【Description of the drawings】
The utility model is further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the overall structure diagram of the utility model adjustable flow velocity connecting tube.
Fig. 2 is the axial schematic cross-sectional view of the utility model X connectors.
Fig. 3 is the axial schematic cross-sectional view of the utility model Y-shaped connector.
【Specific implementation mode】
Shown in please referring to Fig.1 to Fig.3, a kind of adjustable flow velocity connecting tube of the utility model, including conduit 1, X connectors 2, Y
The both ends of connector 3 and flow regulator 4, the conduit 1 are separately connected the X connectors 2 and the Y-shaped connector 3, the flow velocity tune
Section device 4 is set on conduit 1；
The X connectors 2 for connecting central venous catheter (not shown), X connectors 2 include cylindrical internal thread interconnecting piece 21,
Center guide portion 22 and outer end guide portion 23, the center guide portion 22 are connected to the centre bit of cylindrical internal thread interconnecting piece 21
It sets, the outer end guide portion 23 is connected to the outer end of cylindrical internal thread interconnecting piece 21, and is connected with the center guide portion 22；Institute
It states outer end guide portion 23 and the end fitting of central venous catheter matches.
The Y-shaped connector 3 is the big hollow-cone body in the small inner end in outer end for connecting drainage bag (not shown), and hollow-cone
The inner surface of body is equipped with internal thread 32, so as to be connected with the external screw thread taper joint of drainage bag.
Wherein, the conduit 1, X connectors 2, Y-shaped connector 3 are by transparent TPE (High performance polyolefin thermoplastic elastomer) one
Molding, total length about 20cm directly can after X connectors 2 connect central venous catheter, and Y-shaped connector 3 connects drainage bag
To carry out the drainage of the liquid such as ascites, hydrothorax, hydropericardium to patient, it can also pass through the flow regulator 4 in drainage process
Adjust flow velocity.
Although the foregoing describe specific embodiment of the present utility model, those familiar with the art answers
Working as understanding, we are merely exemplary described specific embodiment, rather than for the limit to the scope of the utility model
Fixed, those skilled in the art modification and variation equivalent made by the spirit according to the utility model all should
Cover in the scope of the claimed protection of the utility model.
