Abstract

The utility model relates to a medical air passage building tool, in particular to a tracheal catheter, which comprises a ventilated catheter and a seal air sac, wherein the ventilated catheter is formed by a cannula and a connector, the connector is arranged on the air inlet of the cannula, the seal air sac is formed by a ring type air sac, an inflation/deflation air pipe, an indication air sac and a check valve which are connected in sequence, the ring type air sac is fixed on the air outlet end of the cannula, and an inner hole of the connector is tapered. The tracheal catheter adopting the technical scheme is convenient for a suction catheter of a closed sputum suction apparatus and a hose for injecting medicine to insert.

Description

Endotracheal tube

Technical field

This utility model relates to a kind of medical air flue and sets up instrument, is specifically related to a kind of endotracheal tube.

Background technology

In clinical medicine anesthesia work, endotracheal tube is set up instrument as air flue commonly used and is widely used, and in the first aid of more clinical operation and critical patient, endotracheal tube has also become the indispensable instrument of setting up unobstructed air flue.At present, the endotracheal tube of extensive use includes intubate, union joint, closed airbag and unidirectional gas tube, union joint is arranged on the external end of intubate, union joint is used to connect the respirator mouth, and the other end of intubate is provided with closed airbag, after intubate is inserted patient's trachea, by unidirectional gas tube closed airbag is inflated, with space between sealing trachea and intubate, start respirator, can set up common air flue.

Under a lot of situations, settle the patient respiration road secretions meeting showed increased of endotracheal tube, the accumulation of secretions can influence ventilatory effect, and the medical worker will draw secretions this moment, promptly inhale expectorant.

Existing suction expectorant mode is to adopt the sputum aspirator tube that inserts from union joint; sputum aspirator tube is divided into open and closed two kinds; the not enough health of open sputum aspirator tube; inhale the pollution that the expectorant operation brings in order to reduce; the sputum aspirator of closed commonly used; this device connects the back with the endotracheal tube pipe end and forms a relative airtight space; but traditional catheter slipjoint endoporus 21 is cylindrical; endoporus 21 is level and smooth inadequately to the interface reducing of intubate; as Fig. 3; in addition for avoiding injuring trachea, the sputum aspirator tube insertion end of closed sputum aspirator is very soft all usually, cause the medical worker insert sputum aspirator tube often regular meeting be stuck in the corner of endoporus 21; be difficult to the endotracheal tube that is inserted into promptly and accurately; incur loss through delay and inhale the expectorant time, even can cause the long-time ventilation of patient's trachea not smooth, increase patient's misery.Also may cause patient's anoxia because of same reason prolongs the off line medical care precess time in the time of airway administration, the state of an illness increases the weight of.

In addition, need under some situation toward the intratracheal injection medicine, also can run into the problems referred to above when inserting the flexible pipe of injectable drug.

The utility model content

The technical problems to be solved in the utility model is: the endotracheal tube that provides the flexible pipe of a kind of sputum aspirator tube that makes things convenient for closed sputum aspirator and injectable drug to insert.

In order to solve the problems of the technologies described above, this utility model provides a kind of endotracheal tube, include airway and pressure bladder two parts, wherein airway is made up of intubate and union joint, union joint is arranged on the air inlet of intubate, pressure bladder by the ring type air bag, charge and discharge trachea, pilot balloon and check valve and form, the ring type air bag is fixed on the outlet side of intubate, the ring type air bag, charge and discharge trachea, pilot balloon and check valve and be connected in turn, the endoporus of described union joint is taper.

Adopt the endotracheal tube of technique scheme to have following advantage: 1, because the endoporus of union joint is taper, the reducer of union joint and intubate coupling part, change evenly, can well guide softer sputum aspirator tube and medicine syringe to enter intubate, shorten the time of inserting, improve the efficient of inhaling expectorant and medication, alleviate patient's misery; 2, because the endoporus of union joint is taper, also to be convenient to toward the endotracheal tube injectable drug, the flexible pipe of injectable drug can not be stuck in the endoporus place of union joint.

Description of drawings

Fig. 1 is the structural representation of this utility model endotracheal tube;

Fig. 2 is the union joint cross-sectional view of this utility model endotracheal tube;

Fig. 3 is the union joint cross-sectional view of traditional endotracheal tube.

The specific embodiment

Below in conjunction with drawings and Examples technical solutions of the utility model are further specified:

As depicted in figs. 1 and 2, this utility model provides this utility model that a kind of endotracheal tube is provided, and includes airway and pressure bladder two parts, and wherein airway is made up of intubate 1 and union joint 2, union joint 2 is arranged on the air inlet of intubate 1, and the endoporus 21 of union joint 2 is taper; Pressure bladder by ring type air bag 3, charge and discharge trachea 4, pilot balloon 5 and check valve 6 and form, ring type air bag 3 is fixed on the outlet side of intubate 1, ring type air bag 3, charges and discharge trachea 4, pilot balloon 5 and check valve 6 and is connected in turn.

Concrete using method is: endotracheal tube is inserted the assigned address of patient's trachea, and union joint 2 is connected on the gas outlet of closed sputum aspirator, the air inlet of closed sputum aspirator is connected on the respirator; By to check valve 6 inflation, gas by pilot balloon 5, charge and discharge trachea 4 and enter into ring type air bag 3; The space that ring type air bag 3 expands between sealing trachea and the intubate 1.When needs were inhaled expectorant, the sputum aspirator tube that promotes closed sputum aspirator passed the endoporus 21 of union joint 2 tapers, enters into the gas outlet of intubate 1 smoothly, and then inhales expectorant work by aspirator.

For the method for the flexible pipe that inserts injectable drug, similar to the sputum aspirator tube method of inserting closed sputum aspirator, repeat no more.

Above-described only is preferred implementation of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from this utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that this utility model is implemented.

Claims

1. endotracheal tube, include airway and pressure bladder two parts, wherein airway is made up of intubate and union joint, union joint is arranged on the air inlet place of intubate, pressure bladder by the ring type air bag, charge and discharge trachea, pilot balloon and check valve and form, the ring type air bag is fixed on the outlet side of intubate, the ring type air bag, charges and discharge trachea, pilot balloon and check valve and is connected in turn, and it is characterized in that: the endoporus of described union joint is taper.
