Description

Propelling device for double-cavity catheter

Technical Field

The utility model relates to the field of medical equipment, especially, relate to a advancing device for two-chamber pipe.

Background

The injection type double-cavity PICC catheter is a catheter with the tip of the catheter placed in a superior vena cava or a subclavian vein through superior vena cava puncture under the guiding technology of a color Doppler ultrasound machine, and the catheter is an integrated catheter, wherein two catheter sealing liquids are required to be injected at a constant speed when catheter sealing is carried out, and the injection is finished at the same time, otherwise, the catheter is easier to block the catheter due to the fact that a catheter sealing method is not standard compared with a single-cavity catheter.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that the defects existing in the prior art are overcome, and a propulsion device for a double-cavity catheter, which can hold a double-cavity catheter by a single hand and seal the catheter simultaneously, is provided.

The utility model discloses a realize through following technical scheme:

a pusher assembly for a dual lumen catheter, comprising: the two ends of the connecting belt are respectively and fixedly connected with the holding part and the pushing part,

the symmetry is opened on holding the portion and is had two locating holes, it has two propulsion grooves that set up with the locating hole one-to-one to open in the propulsion portion, and the cylinder of two syringes passes two locating holes respectively, and the handle of syringe supports on holding the portion, and the piston handle of syringe inserts in advancing the groove, and the thumb withstands the propulsion portion outside, and two other fingers support in holding the portion outside, promotes the synchronous propulsion that the thumb can realize two syringes, realizes sealing the pipe simultaneously when carrying out the pipe, effectively prevents the emergence of two-chamber PICC stifled pipe.

Preferably, a step platform is arranged in the propelling groove.

The utility model has the advantages that:

the utility model provides an advancing device simple structure, reasonable in design, convenient to use corresponds two syringes respectively and inserts the locating hole, and the piston handle of syringe inserts and impels in the groove, and the thumb withstands the propulsion portion outside, and two other fingers are supported in the portion of holding the outside, can realize that the one hand impels two syringes in step, accomplishes the tube sealing simultaneously, has reduced the operation degree of difficulty, effectively prevents the emergence of stifled pipe.
