Description
Technical field
The utility model relates to the dedicated a kind of right side bronchus closure of a kind of medical instrument more particularly to newborn to lead
Pipe.
Background technique
With the development of the minimally invasive thoracic surgery of newborn, the case that newborn receives thoracoscopic operation is significantly increased, such as
Congenital tracheoesophageal fistu la etc..Lung isolation one-lung ventilation technology is most important in thoracoscopic operation: guarantee that operation side lung collapses,
And make thoracoscope exposure operating field；It prevents operation side bleeding from flooding strong side lung, causes acute respiratory failure；Prevent operation side lung
It infects sexual secretion or tumour cast enters, cause hospital-acquired infection and tumor planting.Ipsilateral lung, which sufficiently collapses, to be not only convenient for
Surgical procedure, and can promote to collapse side lung and pulmonary vasoconstriction (HPV) occur and change to reduce arteriovenous shunt
Kind one-lung ventilation lower body oxygenation status.
The difficult point of lung isolation one-lung ventilation technology is right lung.It is adult because superior lobe of right lung extended distance knuckle is very close
For 1-2cm, there was only 0.3-0.5cm in newborn and children.So right lung can be blocked and do not block superior lobe of right lung opening be
The key of problem.Existing children's one-lung ventilation lung isolation technology, not can solve this problem.It is lower than 5,000 especially for weight
Gram newborn implement right lung one-lung ventilation, still imperfect solution be isolated.
Newborn's trachea-bronchial epithelial cell and lung's ateliosis, bronchus is tiny and airway tissue is subject to damage.It is existing
With the presence of bronchi plugging catheter tube body it is partially hard, the possibility of easy damaged infant airway tissue；It is larger to block cuff, easily blocking is suffered from
Youngster's upper right lobe of the lung opening；Catheter outer diameter is larger, is not suitable for under-weight newborn.These are exactly that clinician needs urgent solve
Major issue.
Utility model content

Further, 3 outer diameter 1Fr of tube core avoids generating friction with 1 inner wall of tube body, it is ensured that do not drive conduit when detaching
Generate displacement.
Compared with prior art, the utility model has the beneficial effects that
1. truncated cone-shaped, which blocks airbag design, effectively disperses pressure, and meets the growth rhythm of bronchus from thick to thin, in conjunction with
Toughness polypropylene material does not generate elastic expansion after making closure air bag inflation, realizes high appearance low pressure, bronchial simultaneously in closure
It can be with effective protection tracheal wall；
2. tube body material is soft, patient's damage is reduced when implementing tracheae percutaneous transcatheter closure；
3. inflation top layer material is soft and toughness is big, on the basis of slightly increasing conduit diameter, air pressure after inflation is undertaken,
Bronchial while effective protection bronchus is being blocked, the generation of malaise symptoms after tube drawing is reduced.
4. pipe diameter is small, it is suitable for 5KG infant below and implements tracheae percutaneous transcatheter closure；
5. tube body scale uses developing material, developed by X-ray, doctor is helped to determine the position of conduit sealing end in art
It sets；
6. standard inflation/deflation interface is arranged, facilitate inflated for deflated to air bag is blocked in art；
7. setting tube core makes to place the more convenient operation of occlusion catheter in art and guarantees that placement location is accurate.
