Description
Technical field
The present invention relates to field of medical device, and in particular to a kind of two ends connect respectively list（It is many）Cavities conduit pipe and tail adapter road
Catheter connection device.
Background technology
It is cylindrical shape, flexible medical apparatus that known human body inserts conduit, for patient body chamber, pipe, arteries and veins etc.
Fluid（Gas, liquid）Extraction and introducing, such as venous indwelling（Containing PICC), haemodialysis, airway intubation, stomach tube put
Pipe, bladder cannula, serous cavity put pipe etc..
Multi-cavity catheter（Usually two-chamber or three chambers）Can unidirectionally introduce, withdrawn fluid or while introduce and extract stream
Body.Many cavity openings of its insertion body lumen are in parallel or upstream and downstream position, and are in parallel position more the distal end；Many lumen pores
Footpath is equal or different.At present, not yet there is the crossover sub for being exclusively used in conduit, when needing switching flow direction, clinic is generally required
Interruption is original to be fluidly connected, and needs to use pre-flush and the exhaust repeatedly of new consumptive material, wastes fluid（Medicine, blood, heparin
With liquid etc.）, and operating process has an opportunity to be formed bacterium intrusion.
Multi-cavity conversion is often required for clinic, such as：
1st, single lumen catheter inserts body lumen, when tail connects two or more introducing fluid, needs to be introduced not in different periods
Same tail connects medicine；
2nd, multi-cavity catheter is unidirectionally introduced or when the fluid that extracts needs to carry out tube chamber to change；For example：Dual-channel tracheal cannula process
In, catheter opening is typically located at the tube chamber of upstream（Closer to the lobe of the lung）Left principal bronchus is inserted, catheter opening is located at downstream
Tube chamber（Further from the lobe of the lung）In the opening of right principal bronchus, to realize one-lung ventilation, needs need not change breathing circuit
In the case of, realize that the conversion of left and right sides one-lung ventilation avoids lung atrophy, or can be only inserted into right master in two-chamber tracheae distal end connector 2
Under bronchial restrictive condition, it is not necessary to change breathing circuit and realize any One-lung ventilation；
3rd, when the pipeline of multi-cavity catheter introducing and extraction simultaneously needs conversion direction；For example：In blood dialysis, there is flow resistance
The reason for plug is that fibrin sheath is formed, thrombosis and position block.Effective measures for solving flow blocked are included in
By the flow reversal of conduit cavity at the associated blood circuit of hemodialysis unit, blood flow is taken and introduced using pumping（So may be used
Continual cure, but increased the blood flow volume of recycling）, and circuit is disconnected and is coupled again, clinician is increased to leading
The possibility that operate and increased microorganism pollution and infection of pipe, extends the time of dialysis treatment；
4th, each chamber diameter of multi-cavity catheter is different, in the case of causing Peak Flow Rate difference；For example：The big loculuses of PICC put pipe
During rescue severe shock, two-chamber respectively introduces different type medicine.
By retrieval, " Yichang First People's Hospital ", the middle promulgated by the State Council of Application No. " 201220047744.5 " are retrieved
Bright patent, it discloses " a kind of medical multifunctional crossover sub ", and it is a both ends open, hollow fusiformis body, the fusiformis
