Description
Technical field
The present invention relates to field of medical device, and in particular to a kind of two ends connect list respectively（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Multi-cavity catheter（Usually two-chamber or three chambers）Can unidirectionally introduce, withdrawn fluid or simultaneously introduce and extract stream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 that is exclusively used in conduit, it is necessary to during switching flow direction, clinic is generally required
Interruption is original to be fluidly connected, and needs to use new consumptive material pre-flush and exhaust repeatedly, wastes fluid（Medicine, blood, heparin
With liquid etc.）, and operating process has an opportunity to be formed bacterium intrusion.And after multi-cavity catheter is inserted, the mode in tail adapter road compares
It is fixed, it is impossible to realize that multi-chamber confluxes.
Required for multi-cavity conversion is often clinical, such as：
1st, single lumen catheter inserts body lumen, and tail is connect when two or more introduces fluid, it is necessary 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）Opening in right principal bronchus, to realize one-lung ventilation, it is necessary to breathing circuit need not changed
In the case of, realize that the conversion of left and right sides one-lung ventilation avoids lung atrophy, or right master is can be only inserted into two-chamber tracheae distal end connector
Under bronchial restrictive condition, it is not necessary to change breathing circuit and realize any One-lung ventilation；
3rd, when multi-cavity catheter introducing simultaneously and the pipeline for extracting need 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
Operating and increased microorganism pollution and the possibility of infection for 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：Put pipe in PICC sizes chamber
During rescue severe shock, two-chamber respectively introduces different type medicine.
After multi-cavity catheter is inserted, multi-cavity confluxes cannot be realized in the past.
Multi-chamber confluxes can cause that the aperture utilization ratio of multi-cavity catheter is maximized.Forward multi-cavity confluxes so that extracting out
The fluid of patient is exported from single-chamber, is easy to centrally dispose in the case of the max-flow scale of construction；Reverse multi-cavity confluxes so that from single-chamber
The flow for introducing patient increases（Especially in the case of the diverse location of patient end multi-cavity opening）.
During putting pipe rescue severe shock such as PICC two-chambers, confluxed joint using this conversion, it is possible to achieve two-chamber is simultaneously
Blood plasma product is introduced, and retains the possibility for being rapidly introduced into salvage drug.
As a large amount of hemopericardiums cause pericardial tamponade, insert during the rescue of double channel catheter drainage, can be by this turn
Exchange stream joint, the maximum amount of quick extraction hematocele to same blood recovery device.After multi-cavity catheter is inserted, multi-cavity confluxes
Cannot realize in the past.
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 ", it is a both ends open, hollow fusiformis body, the fusiformis
Body case is annular step ladder-shaper structure, and the linking for solving different size conduit can not solve what is referred in background technology
Technical problem.Relevant single-chamber, two-chamber, three chambers and multi-cavity catheter or confluxing for joint fail to retrieve Patents or document.
