Abstract

The utility model belongs to an implement which inputs the medium into the human body, particularly a two-chamber trachea catheter for a baby. An inner tube of the utility model is contained between cavities of outer tubes. An inner cavity of a catheter is divided into primary structures of two hollow cavities which are not communicated. The outsides of tube walls of the outer tube and the inner tube are provided with a cuff breather tube, a swelling hook, etc. In such a way, a sputum aspirator is successfully put in the inner tube. Double lungs of the baby which is done the transient tachypnea operation are respectively ventilated. The utility model solves the problem of the lower success ratio of the emergency treatment that a respirator is stopped for sucking the sputum when the baby is done the in surgery of the lung. The utility model is an air breather which is particularly suitable for the surgery of the lung of the baby.

Description

Two-chamber trachea catheter for baby

This utility model belong to medium fail in or input people intravital apparatus, particularly children's's double-lumen catheter.At present, the clinical endotracheal tube that is used for the pneumochirurgia surgery anesthesia has 2 kinds: single lumen catheter and adult type double lumen tube, single lumen catheter is a single tube, only the bilateral lung is ventilated simultaneously, adult's double lumen tube adopts parallel two tubes to the both sides pulmonary ventilation, exist single lumen catheter and be unsuitable for wet lung operation (as pulmonary abscess, lung cyst, massive hemoptysis), the adult type double lumen tube is difficult to insert sputum aspirator tube for a short time because of interior tube chamber footpath, deficiency such as airway patency when being not easy to guarantee operation.

The purpose of this utility model is to provide the double-lumen catheter of a kind of children's's of being used for pneumochirurgia surgery anesthesia, take trouble lung and strong lung are separated, in case pathological changes or secretions block through bronchogenic spread or generation acute respiratory, in the design of caliber, make technical measures such as all can inserting sputum aspirator tube in the inner and outer pipes smoothly overcome the deficiency of prior art.

Overall structure of the present utility model is:

Be divided into interior pipe (2), outer tube (1), tracheal tampon (4), cover capsule breather (3), knuckle hook ingredients such as (5) on children's's double-lumen catheter structure, the opening part of inner and outer pipe is aimed at two bronchus respectively, the knuckle hook is on the tube wall between the inner and outer pipe opening, be contained between the outer tube tube chamber in the pipe in it is characterized in that, conduit cavity is divided into disconnected two cavitys mutually.

Other structures of the present utility model also have:

Tracheal tampon is in communication with the outside by the cover capsule breather in the catheter wall.

Accompanying drawing of the present utility model has:

Fig. 1 is the profile of children's's double-lumen catheter;

Fig. 2 is children's's double-lumen catheter sectional view.

Accompanying drawing has provided embodiment of the present utility model, and accompanying drawings is as follows:

Conduit adopts soft materials such as the latex tubing making that constitutes helical stent with nylon yarn, interior pipe is connected with the outer tube inscribe, inner tube diameter is 3.78mm, outer tube diameter is 6.5mm, inner tubal wall thickness is 0.75mm, and outer tube wall thickness is 1.1mm, and catheter length is 25cm, double channel catheter and anesthesia outfit link can be ventilated respectively, and strong lung is aimed at the tube opening place in the conduit insertion end; Be not communicated with mutually between the two spider capsule tracheas that cover capsule on the inside and outside tube wall is connected, 1/3 place, middle part and vertical direction are 75 angle bendings on the conduit, are 45 ° of angle bendings at knuckle hook place and horizontal direction.

Substantive distinguishing features of the present utility model and obtained technological progress are:

1, the theoretical structure that is contained in the inner tube among the outer tube tube chamber that adopts of the non-uniform Distribution of design consideration diameter of the present utility model, the inner and outer pipes opening is aimed at respectively two lungs makes two pulmonary ventilation separately, both can distinguish inhalation anesthesia gas, also can be only with strong lung tube chamber administration of anaesthetic and ventilation.

2, make in the design of inside and outside caliber and all can insert smoothly a large amount of pathology secretion that the sputum aspirator tube drainage suffers from lung normally carrying out with the unobstructed and operation that ensures respiration in the inside and outside tube chamber.

3, be used for the especially wet lung surgery anesthesia of Lungs of Children operation anesthesia that single lumen catheter is difficult to be competent at.

Claims

1, is divided into interior pipe (2), outer tube (1), tracheal tampon (4), cover capsule breather (3), knuckle hook ingredients such as (5) on children's's double-lumen catheter structure, the opening part of inner and outer pipe is aimed at two bronchus respectively, the knuckle hook is on the tube wall between the inner and outer pipe opening, be contained between the outer tube tube chamber in the pipe in it is characterized in that, conduit cavity is divided into disconnected two cavitys mutually.

2, double-lumen catheter according to claim 1 is characterized in that tracheal tampon is in communication with the outside by the cover capsule breather in the catheter wall.

3, double-lumen catheter according to claim 1 is characterized in that catheter length is not less than 20cm, and inner tube diameter is 3.43-4.14mm, and outer tube diameter is 6-7mm, the thick 0.5-1mm of inner tubal wall, outer tube wall thickness 1-1.5mm.
