Description

A kind of Respiratory Medicine trachea cannula
Technical field
The utility model belongs to technical field of medical instruments, is related to a kind of Respiratory Medicine trachea cannula.
Background technology
Intubation and general anaesthesia operation is that trachea cannula direct oral cavity or nasal cavity are placed into person's windpipe, to ensure operation The good ventilation of period patient, trachea cannula clinically using for a long time, trachea cannula it be treatment and improve patient respiratory to decline Indispensable medical assistance apparatus is exhausted, is contributed to rescue the patient of respiratory failure, trachea cannula preferably has enough rigidity, Resist discounting or kink.The trachea cannula that Hospitals at Present uses is by the airbag aeration for being located at body bottom, then in profit Body is positioned in the tracheae of patient with the air bag after expansion, the gap between trachea cannula and tracheae is filled after gas injection, is prevented Leak-stopping gas, mechanical ventilation effect is influenceed, compressing is produced to the mucous membrane of endotracheal fixed position after its inflation, it is long-term use of easy Tunica mucosa tracheae ischemic necrosis or granulation tissue growth at compression are caused, and then produces serious consequence, threatens the health of patient.
In addition, suction sputum is an important measures in trachea cannula in the treatment work of urgent patient, the purpose is to will exhale The secretion for inhaling road suctions out in time, to maintain unobstructed artificial airway, the enough ventilations of guarantee and abundant gas exchanges, and meanwhile it is also right It is significant to prevent and treat pulmonary infection.Open suction sputum nurse must ceaselessly disconnect lung ventilator and be inserted with patient's trachea The connection of pipe, insertion sputum aspirator tube carrys out suction sputum in trachea cannula, and this is danger close for the patient of no autonomous respiration , can only be before suction sputum first to the oxygen of patient's suction high-purity, but during suction sputum, patient still occurs larger Somatic reaction;Besides because sputum aspirator tube is much thinner than tracheal catheter, sputum easily sprays from tracheal catheter, and pollution doctors and patients are double Side.
Patent CN200720195220.X discloses a kind of trachea cannula, including software intubation, and software intubation is provided with gas Capsule, air bag are connected by gas tube with push type gas cell, and its main points is that the side of the software intubation is provided with humidifying suction sputum two With pipe, the insertion end mouth of pipe of the dual-purpose pipe of humidifying suction sputum connects with software intubation, and the mouth of pipe of the dual-purpose pipe of humidifying suction sputum is provided with cap stopper, The insertion end of described software intubation is provided with side opening.The patent realizes carries out humidifying suction sputum work during lung ventilator connects Make, but still problems be present:(1) or traditional monosaccate designs, and uses for a long time and tunica mucosa tracheae is damaged; (2) the dual-purpose pipe of humidifying suction sputum is connected in trachea cannula outer wall, while insertion patient airway, increases insert external diameter, no Plugged beneficial to intubation, increase the sense of discomfort of patient.
Utility model content
According to above the deficiencies in the prior art, the utility model provides a kind of Respiratory Medicine trachea cannula, using double gas The fixed mode of capsule alternating, avoids causing local tunica mucosa tracheae compressing to injure, and can keep exhaling during humidifying suction sputum The normal work of suction machine.
A kind of Respiratory Medicine trachea cannula described in the utility model, including body, on described bottom of the pipe outer wall It is surrounded with air bag A, described air bag A and passes through inflatable interface A phases external with body upper end the inflation tube chamber A in body Even, it is characterised in that:Air bag B, described air bag B are also surrounded with described close air bag A tube wall and passes through pipe Inflatable interface B external with body upper end internal inflation tube chamber B is connected;The air inlet of described body is connected with three and connected Mouthful, the interface of described three-way interface is respectively trachea cannula interface, lung ventilator interface, humidifying suction sputum interface, wherein, it is described Humidifying suction sputum interface and trachea cannula interface are coaxial, described lung ventilator interface along obliquely downward to access to humidifying suction sputum interface with In tube chamber between trachea cannula interface, closure is provided with described humidifying suction sputum interface.
The utility model takes double bolloon to design, and two air bags inflate fixed trachea cannula in turn, and prevent gas leakage, really Mechanical ventilation effect is protected, and avoids single air bag and for a long time local tunica mucosa tracheae is caused to oppress, ensure that patient health. The addition of three-way interface, the work of humidifying suction sputum and lung ventilator work can be carried out simultaneously, due to constantly to be lifted during suction sputum Sputum aspirator tube, thus humidifying suction sputum interface and trachea cannula interface is coaxial, facilitate suction sputum.Humidifying and suction sputum work are not being needed When, it is only necessary to close top cover labyrinth.
Wherein, preferred scheme is as follows:
Described air bag A and air bag B holds low-pressure type air bag to be high.
Described body and the inside and outside wall of three-way interface are coated with silver ion coating.Silver ion coating has antibacterial Effect, meet the needs of clinical health.
Each interface of described three-way interface is provided with sealing ring.
Valve for preventing reverse-flow is provided with described humidifying suction sputum interface, described valve for preventing reverse-flow is the silica gel with cross recess Valve.Sputum is excessive during valve for preventing reverse-flow can avoid suction sputum, pollutes doctor and patient.
Described lung ventilator interface is accessed between humidifying suction sputum interface and trachea cannula interface along obliquely downward to 45 degree of angles In tube chamber.
Beneficial effect is possessed by the utility model:(1) double bolloon design distinguished in traditional monosaccate to local gas The long-time compressing of pipe mucous membrane, reduce the incidence of complication in endotracheal intubation;(2) three-way interface is added, is realized The work of humidifying suction sputum and lung ventilator work can simultaneously be carried out, and in humidifying suction sputum interface are provided with valve for preventing reverse-flow, can be with Sputum is excessive during avoiding suction sputum, pollutes doctor and patient.
