Abstract
The invention discloses a low-pressure two-bag self-suction tracheal catheter. The low-pressure two-bag self-suction tracheal catheter comprises a tracheal catheter body, a tracheal catheter connecting port, an air bag inflation tube, an upper air bag, a lower air bag, an upper air bag inflation valve, a lower air bag inflation valve and a suction tube. The tracheal catheter connecting port is connected to the tracheal catheter body. The upper air bag and the lower air bag are both connected with the air bag inflation tube. The air bag inflation tube is connected with the upper air bag inflation valve and the lower air bag inflation valve. The upper air bag and the lower air bag are arranged at the tail end of the tracheal catheter body. The upper air bag is arranged above the lower air bag. A suction tube opening is arranged above the lower air bag. The suction tube extends upwards to the upper end of the tracheal catheter body through the inner wall of the tracheal catheter body and penetrates out of the tracheal catheter body to be connected with a suction tube connecting port, and a sealed opening is formed in the tail end of the suction tube connecting port. The low-pressure two-bag self-suction tracheal catheter is ingenious in structure; by inflating the upper air bag and the lower air bag alternately, compression of the air bags to the inner wall of the trachea is relieved, and avascular necrosis of trachea mucosa is prevented; besides, before the lower air bag is deflated, secreta in the trachea above the lower air bag can be sucked cleanly through the suction tube, so that pulmonary infection caused when the secreta flows into the lower respiratory tract is prevented.
Description
Technical field
The present invention relates to the two capsule self-gravitation endotracheal tube in medical aid field, particularly a kind of low pressure and using method thereof.
Background technology
There are two important problems in existing single-lumen bronchial tube:
First, existing single-lumen bronchial tube only has single air bag usually, and fill up the air bag on endotracheal tube when tracheal intubation after, air bag has fixing endotracheal tube, seals, prevents the effect of gas leakage.But after air bag fills up, air bag can produce compressing to tunica mucosa tracheae, and long compressing can make tunica mucosa tracheae ischemic necrosis, causes the tracheomalacia in later stage, to subside or narrow, produce serious adverse consequences.So, clinical often need to air bag deflation 1 time after air bag fills up every 4 ~ 6h, each 5 ~ 10min, in order to alleviate the compressing that air bag produces tunica mucosa tracheae, but, because only have an air bag, if bled, decompression there will be again poorly sealed and leaks gas, and this contradiction all cannot solve so far.
Secondly, existing single-lumen bronchial tube self is without suction device.When carrying out suction sputum operation, can only insert the secretions of below sputum aspirator tube attraction tracheal tube opening by transtracheal catheters tube chamber, certainly, secretions more than glottis can direct oral cavity, nasal cavity attract.But glottis is cannot directly attract down to the endotracheal secretions of this section, endotracheal tube air bag.Each before extracting endotracheal tube, air bag is all needed to find time, and while air bag is found time, more than air bag endotracheal secretions will flow into the tracheal strips of below air bag instantaneously, although can insert sputum aspirator tube attraction by transtracheal catheters tube chamber, cannot exhaust completely, the secretions of non-sucking-off flows into trachea deep even may cause bronchial blocking in bronchus, pulmonary atelectasis, pulmonary infection etc., have a strong impact on the prognosis of patient.As attraction tracheal tube under Authorization Notice No. Chinese patent glottis disclosed in CN204745259U, by arranging air bag groove in air bag upper end, improving sealing effectiveness, still only having an air bag, still can produce compressing to inner surface of trachea.
Summary of the invention
The invention provides the two capsule self-gravitation endotracheal tube of a kind of low pressure and using method thereof, by double bolloon, the mode of alternately inflation alleviates the compressing of air bag to local inner surface of trachea, the ischemic necrosis of prevention tunica mucosa tracheae.
The technical solution used in the present invention is:
The two capsule self-gravitation endotracheal tube of low pressure, comprise endotracheal tube, endotracheal tube interface, airbag inflation pipe, upper gasbag, lower gasbag, upper gasbag charge valve, lower gasbag charge valve and suction catheter, endotracheal tube interface is connected on endotracheal tube, upper gasbag and lower gasbag are all connected an airbag inflation pipe, airbag inflation pipe is connected to respectively upper gasbag charge valve and lower gasbag charge valve, upper gasbag and lower gasbag are arranged on endotracheal tube end, upper gasbag is arranged on above lower gasbag, suction catheter opening to be arranged on above lower gasbag and to be close to lower gasbag upper limb, suction catheter transtracheal catheters inwall goes upward to endotracheal tube upper end and passes, be connected with suction catheter interface.
Further, suction catheter interface end is provided with sealing, can control opening and the closedown of suction catheter.
Preferably, upper gasbag and lower gasbag are low pressure air bag, and pressure limit is 1.961kPa ~ 2.492kPa.
The using method of the two capsule self-gravitation endotracheal tube of low pressure, comprises the following steps:
Two for low pressure capsule self-gravitation endotracheal tube is inserted trachea and after determining position, lower gasbag is inflated, fixing endotracheal tube, after 4-6 hour, open the sealing of suction catheter interface end, siphon away the secretions above lower gasbag, fill up upper gasbag, then to find time lower gasbag, alleviate the pressurized of lower gasbag place tunica mucosa tracheae, after 4-6 hour, fill up lower gasbag, then to find time upper gasbag, alleviate the pressurized of upper gasbag place tunica mucosa tracheae.So, by every 4-6 hour alternately to upper and lower airbag aeration, the mode of bleeding, air bag can be avoided to oppress the tunica mucosa tracheae of a certain position for a long time and cause the ischemic necrosis of tunica mucosa tracheae.In addition, at every turn before by the evacuating air in lower gasbag, all need the sealing of opening suction catheter interface end, siphon away endotracheal secretions above lower gasbag.
The invention has the beneficial effects as follows:
The invention alleviate the compressing of air bag to local inner surface of trachea, the ischemic necrosis of prevention tunica mucosa tracheae by the mode of upper and lower air bag alternately inflation; Each lower gasbag is bled before, can by suction catheter by secretions exhaustion endotracheal above this air bag, thus prevent endotracheal secretions above lower gasbag from flowing into trachea deep even in bronchus; By suction catheter to the endocrine attraction of trachea above lower gasbag, the glottis that can exhaust is to the endotracheal secretions of endotracheal tube lower gasbag this section.
