Abstract

The utility model relates to a trachea cannula with a phlegm suction cavity and relates to a medical gas suction apparatus, in particular to a trachea cannula used for tracheotomy. The trachea cannula comprises a cannula body, a respirator interface and a balloon and further comprises an airway inner tube and a negative pressure suction tube interface. The two ends of the airway inner tube are connected with the cannula body in a sealed mode, and the phlegm suction cavity of an interlayer structure is formed in the cannula body. The airway inner tube is communicated with the phlegm suction cavity through phlegm discharge holes distributed in the airway tube wall. The phlegm suction cavity is communicated with an external negative pressure suction device through the negative pressure suction tube interface, the negative pressure suction tube interface is connected to the upper end of the cannula body and close to the respirator interface, and a one-way valve capable of being opened outwards is arranged on the negative pressure suction tube interface. According to the trachea cannula, phlegm is discharged through the phlegm cavity of the interlayer structure in the cannula body and the phlegm discharge holes so that the phlegm can be prevented from accumulating in the airway for a long time to form phlegm scabs, the probability that phlegm scabs are formed in the trachea cannula is lowered, and stimulus to the trachea wall and injury to the airway mucosa caused by phlegm suction of the cannula are avoided.

Description

A kind of tracheal casing pipe with suction sputum chamber
Technical field
This utility model relates to medical gas inhalation apparatus, especially relates to the trachea intubate for tracheotomy.
Background technology
Setting up artificial airway, is the anxious Cavity in Critical Patients effective means of clinical rescue.Tracheotomy can prevent or remove rapidly respiratory tract obstruction, increases effective ventilatory volume, nurses and properly can save patient's life, if the improper expectorant crust that easily forms in sleeve pipe of nursing is stopped up trachea, causes patient to suffocate.In clinical use, may be because of humidifying deficiency in sleeve pipe, suction sputum method is improper, patient's expectoration is unable, leptochymia causes the many reasons such as thick sputum, so that sputum is attached to autogenous cutting air flue tube wall for a long time, thus overheap forms expectorant crust.How to reduce expectorant crust formation probability in sleeve pipe is to set up the large nursing difficult problem of artificial airway patient one and emphasis always.
Chinese utility model patent " Subglottic suction tube tracheal cannula " (utility model patent number: ZL200920308644.1 Granted publication number: CN201492783U) discloses a kind of Subglottic suction tube tracheal cannula, comprise tracheal casing pipe, respirator interface, air bag, airbag inflation pipe, in tracheal casing pipe, be provided with a groove, sputum aspirator tube is embedded in groove.The lower surface of tracheal casing pipe, upwards opens a groove backward to the top of sleeve pipe apart from air bag trailing edge l-2cm place.Sputum aspirator tube is embedded in groove by adhesives.Sputum aspirator tube front end exceeds the front end 2-3cm of four grooves of inlaying, 15 °-20 ° of the front end of sputum aspirator tube and the angles of tracheal casing pipe, and there are 2 apertures sputum aspirator tube front end side; The other end of sputum aspirator tube connects vacuum suction equipment.This utility model utilization bonding is embedded in the sputum aspirator tube of tracheal casing pipe lower surface, under sucking-off glottis, with the secretions in air bag gap, to prevent that secretions from flowing into patient's pulmonary, reduces the generation of pneumonia, reduces patient's mortality rate.Chinese utility model patent " pipe tracheal casing pipe " (utility model patent number: ZL201120043175.2 Granted publication number: CN202028015U) discloses and the utility model discloses a kind of tracheal casing pipe, comprises trocar sheath and inner sleeve, the inner core supporting with it; Inner sleeve is provided with holder second; Holder second is provided with fore shaft; Outer sleeve upper is provided with holder first, and holder first is provided with frenulum hole, groove and cannula lock, and the lower end of described trocar sheath is entire straight flange.This utility model has for having solved the defect that hinders sense when the trocar sheath lower ending opening of prior art disposable tracheal tube waste material, metal tracheal casing pipe is turned causes suction sputum greatly.But these technical schemes all can not solve in existing tracheal casing pipe and easily form expectorant crust, if nurse the improper trachea that may cause stopping up, even cause the problem that patient suffocates.For preventing that expectorant crust from forming, the veteran nursing staff of needs spends the plenty of time, energy carries out Airway Care, and this need to expend a large amount of Nursing manpower costs.Except conventional sputum aspirator tube, Airway Care also adopts various forms sleeve brush to clean tube wall sputum with water, cleans with water in operating process and easily causes again expectorant crust to drop to the risk of air flue.
Utility model content
The purpose of this utility model is to provide a kind of tracheal casing pipe with suction sputum chamber, can carry out at any time intermittent vacuum suction expectoration, can reduce the tracheal casing pipe of expectorant crust formation probability in sleeve pipe, solve existing tracheal casing pipe and easily form expectorant crust, nurse the improper trachea that may cause stopping up, even cause the problem that patient suffocates.
This utility model solves the problems of the technologies described above adopted technical scheme:
With the tracheal casing pipe in suction sputum chamber, comprise casing main body, respirator interface and air bag, is characterized in that:
Described tracheal casing pipe also comprises air flue inner tube and vacuum suction interface tube; Two ends and the casing main body of described air flue inner tube are tightly connected, in the inner suction sputum chamber that forms sandwich of casing main body;
Described air flue inner tube, by being distributed in the expectoration hole on air flue tube wall, is communicated with described suction sputum chamber;
Described suction sputum chamber, by vacuum suction interface tube, is communicated to outside vacuum suction equipment.
The preferably technical scheme of one of the tracheal casing pipe with suction sputum chamber of the present utility model, is characterized in that described vacuum suction interface tube is connected to the upper end of casing main body, near the position of respirator interface.
The better technical scheme of one of the tracheal casing pipe with suction sputum chamber of the present utility model, is characterized in that described vacuum suction interface tube is provided with the one-way cock that can outwards open.
The beneficial effects of the utility model are:
1, the tracheal casing pipe with suction sputum chamber of the present utility model, utilize suction sputum chamber and the expectoration hole of casing main body inner sandwich structure to discharge sputum, avoid sputum to be collected at for a long time formation expectorant crust in air flue, thereby can reduce expectorant crust formation probability in tracheal casing pipe, reduce expectorant crust and stop up trachea, the risk that causes patient to suffocate.
2, the tracheal casing pipe with suction sputum chamber of the present utility model, discharges sputum by casing main body inner sandwich structure and reduces sputum aspirator tube, can avoid the stimulation to tracheal wall and the air flue mucosa injury that in the time of sleeve pipe suction sputum, cause.
