Description

Trachea cannula capable of preventing nasal wing from being pressed

Technical Field

The utility model relates to the technical field of medical equipment, it is specific, relate to a prevent trachea cannula of oppression alar.

Background

At present, after partial surgery, a patient in oral and maxillofacial surgery usually adopts a mode of keeping a transnasal tracheal cannula to ensure the patency of an airway.

In order to prevent the situation that the intubation tube is crushed to cause blockage of the intubation tube, the existing endotracheal tube is usually made of a material with high strength and high breaking resistance, when one end of the endotracheal tube is inserted into a trachea, the other end of the endotracheal tube is upwards connected to medical equipment through a nose, the endotracheal tube directly presses the inner wall of a nasal wing of a patient, and the pressed nose is in a low-perfusion or ischemia state for a long time, so that the nasal pressure sore is easily caused.

Clinically, in order to prevent the nasal pressure sore of the patient after the operation through the nasal trachea cannula, medical gauze is usually inserted between the inner wall of the nasal wing of the patient and the trachea cannula, or a medical adhesive tape is used for binding the nasal wing pressed by the trachea cannula after one section is pressed downwards. However, both of these methods may bring a certain discomfort to the patient, and at the same time, the anti-compression effect is weak.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the problem that the nasal part is pressed to sore when the existing trachea cannula mentioned in the background easily oppresses the inner wall of the nasal wing of a patient.

In order to achieve the above object, the utility model provides a prevent to oppress trachea cannula of alar, including intubate, cover bag pipe and connector, cover bag union coupling is in on the intubate outer wall, the connector is installed the one end of intubate, its characterized in that, the junction of cover bag pipe and intubate arrives intubate part between the connector or whole bellows that are.

It can be understood that the section of the tracheal cannula away from the nose is provided with a corrugated pipe, and the corrugated pipe is characterized by being capable of bending towards any direction and having stability. The design is convenient for the trachea cannula to freely turn after leaving the nose to be connected with the medical equipment, and the pressure on the nasal wings of a patient is reduced or even avoided.

Furthermore, supporting rings are arranged at the wave crest and the wave trough of the corrugated pipe.

It will be appreciated that the design of the support ring further prevents collapse of the bellows.

Further, the support ring is made of polypropylene plastic.

It can be understood that the polypropylene material has higher hardness and toughness, and the support ring made of the polypropylene material has better compression resistance.

Further, the length of the corrugated pipe is 10 centimeters.

It will be appreciated that the bellows length is too short to achieve the effect of free steering, or that free steering can result in over-stretching of one side of the bellows and over-compression of the other side. And the length overlength of bellows can lead to the flat ability of resistance to compression and the stability decline of whole trachea cannula, consequently, the bellows length design of trachea cannula that this scheme disclosed is 10 centimetres, guarantees to realize that the bellows can freely turn to, and is convenient when the connector is connected with medical equipment, has also compromise whole trachea cannula's stability.

Furthermore, a backing ring is installed on the insertion tube adjacent to the corrugated tube, and the backing ring is located at one end, far away from the connector, of the corrugated tube.

It can be understood that, when the trachea cannula disclosed by the scheme is used, the backing ring can be positioned on the inner wall of the nasal wing of the patient and close to the outlet, and the hard cannula is prevented from directly contacting with the inner wall of the nasal wing of the patient.

Further, the grommet is a damped sliding fit over the cannula.

It can be understood that the position of the backing ring can be adjusted according to different conditions of patients to achieve the best effect, and meanwhile, the damping sliding mode can prevent the backing ring from accidentally sliding out of the nasal cavity of the patient or sliding into a deeper position of the nasal cavity of the patient when the cushion ring is used, so that discomfort is brought to the patient.

Furthermore, the backing ring is made of a silica gel material.

It can be understood that the silica gel is non-toxic to human bodies and has good softness, and the cushion ring made of the silica gel material is convenient for improving the comfort level of patients during treatment.

Further, the intubate is kept away from the guide head is installed to the one end of connector, the guide head is the cylindric structure of bottom surface for the arcwall face, just guide head side and arc bottom surface all are equipped with the bullport.

It will be appreciated that the cylindrical design with the bottom surface being an arcuate surface prevents the harder leading head from puncturing the patient's trachea.

To sum up, the utility model discloses a prevent trachea cannula of oppression alar, solved current trachea cannula oppress patient's alar inner wall easily when using, cause the problem that the sore was pressed to the nasal part, also improved the patient comfort level when the treatment simultaneously.
