Description

Artificial airway atomizer

Technical Field

The utility model relates to an artificial airway atomizer.

Background

The artificial airway comprises a tracheal cannula and a tracheotomy, is an artificial respiration channel established for rescuing and treating critically ill patients and is generally connected with a respirator for assisting respiration. Along with the improvement of the state of an illness of a patient, when an offline indication exists, the clinical practice generally keeps the artificial airway while trying to take the offline, and simultaneously performs ordinary oxygen inhalation or liquid medicine atomization inhalation on the artificial airway to play a role in treating and humidifying the artificial airway.

Clinically used nebulizing inhalers are generally not suitable for such patients who remain with endotracheal intubation after they are taken off-line. The most common ordinary inhaler that atomizes clinically is the face guard formula and holds the formula, does not have the atomizer identical with artifical air flue, more common is to use the face guard formula atomizer after the improvement to be used for the patient of tracheotomy, cover in tracheotomy open end after the high flow oxygen source is connected to face guard atomizer flourishing atomizing liquid medicine promptly, its drawback lies in that the bore is inconsistent leads to the atomizing excessive to cause the waste, and need artifical the intermittent continuous adding of continuation because of the liquid medicine that lasts the atomizing, also have when bringing work load for the nurse because of leaking and causing empty bottle high flow oxygen to inhale the risk that increases the air flue drying. In addition, the tracheotomy atomization mask used at present can have the phenomena of mask displacement and the like when a patient moves slightly, and even can cause the situations of splashing of liquid medicine and the like.

SUMMERY OF THE UTILITY MODEL

The utility model provides an artifical air flue atomizer can realize both being applicable to the tracheotomy and also being applicable to trachea cannula patient's aerosol inhalation purpose, has improved patient's comfort level and nursing security.

According to a first aspect of the embodiments of the present disclosure, an artificial airway atomizer is provided, which includes a closed atomization bottle and a connecting pipe for conveying gas atomized by the atomization bottle to an artificial airway, wherein a gas outlet of the connecting pipe is matched with a gas inlet of the artificial airway;

wherein, the atomizing bottle includes:

the air chamber is gradually reduced and increased in caliber from bottom to top and comprises an air inlet at the bottom, a liquid inlet at the side surface and an air outlet at the top;

the oxygen pipe interface is communicated with the air inlet of the air chamber through an oxygen channel;

the liquid containing cavity surrounds the periphery of the air chamber, and the caliber of the liquid containing cavity is gradually reduced and increased from bottom to top;

the medicine inlet is communicated with the liquid containing cavity;

and the mist outlet channel is connected with a gas outlet at the top of the gas chamber and discharges the atomized gas.

Optionally, the connecting pipe is connected with the mist outlet channel through an extension pipe.

Optionally, a mask is provided on the connecting tube.

Optionally, the mask and connecting tube are of unitary construction.

Optionally, the connecting pipe is of a hollow structure.

Optionally, a spacer is fixed in the air chamber, and a gap for the atomized airflow to pass through is formed between the spacer and the inner wall of the air chamber.

Optionally, the liquid holding chamber is funnel-shaped.

The beneficial effect of this disclosure: the device is suitable for tracheotomy and aerosol inhalation of a patient with tracheal intubation, and the phenomena of splashing of liquid medicine, pulling of an artificial airway and the like can not occur when the patient changes the body position, and the oxygen tube can not fall off, so that the comfort level and the nursing safety of the patient can be improved; in addition, the continuous instillation of the liquid medicine can be ensured, and the workload of nurses is reduced.

Drawings

The present disclosure is described in further detail below with reference to the attached drawings and the detailed description.

Fig. 1 is a schematic diagram of an artificial airway nebulizer according to an exemplary embodiment.

Detailed Description

Fig. 1 is a schematic structural diagram of an artificial airway nebulizer according to an exemplary embodiment, and as shown in fig. 1, the nebulizer includes a connecting tube 2 and a nebulizing bottle 6, the connecting tube 2 is connected with the artificial airway, and the gas nebulized by the nebulizing bottle 6 is delivered to the artificial airway. The air outlet of the connecting pipe 2 is matched with the air inlet of the artificial air passage, the connecting pipe 2 can be inserted into the artificial air passage and the artificial air passage can be inserted into the connecting pipe 2, the fastening connection of the atomizer and the artificial air passage is realized, and the problems that liquid medicine mist overflows to cause waste and cannot reach a humidified air passage due to the fact that the interfaces of a common atomizing inhaler and the artificial air passage are inconsistent are solved.

Connecting pipe 2 accessible extension pipe 14 is connected with atomizing bottle 6, and extension pipe 14 has the flexibility, and length is longer, can prevent to cause the tractive to artifical air flue when the patient changes the position. Connecting pipe 2 can be hollow out construction, and its effect lies in that the gas of following artifical air flue exhalation can be followed the fretwork and split the external world, and the fretwork design can make things convenient for the nurse to inhale the phlegm operation to the patient and not influence patient's atomizing inhalation. Be equipped with face guard 1 on connecting pipe 2, the effect of face guard 1 mainly prevents the sputum splash, keeps sanitation and hygiene, and face guard 1 and connecting pipe 2 formula structure as an organic whole.

The atomizing bottle 6 is a closed structure and comprises a medicine inlet 3, an atomizing channel 5, a liquid containing cavity 8, an air chamber 10, an oxygen tube interface 13 and the like. The diameter of the air chamber 10 is gradually reduced from bottom to top, and the longitudinal section of the air chamber is of a triangular structure. The bottom of the air chamber 10 is provided with an air inlet, an oxygen pipe interface 13 is connected to the air inlet through an oxygen channel 12, the oxygen pipe interface 13 is used for being connected with an air source, and the oxygen channel 12 can be arranged along the inner wall of the atomization bottle 6; the side surface of the air chamber 10 is provided with a plurality of liquid inlets 9 for the liquid medicine 7 in the liquid containing cavity 8 to flow in; the top of the air chamber 10 is an air outlet connected with the mist outlet channel 5, and the mist outlet channel 5 can be connected with an extension pipe 14 to discharge the atomized air. A spacer 11 is fixed in the air chamber 10, the spacer 11 can be horizontally placed, and a gap for atomized airflow to pass through is formed between the spacer 11 and the inner wall of the air chamber 10.

The liquid containing cavity 8 surrounds the air chamber 10, and the liquid medicine 7 can be injected into the liquid containing cavity 8 through the medicine inlet 3 on the bottle body. The liquid containing cavity 8 gradually decreases in diameter from bottom to top and is of a funnel-shaped structure, and the air chamber 10 can be located on the central axis of the funnel-shaped liquid containing cavity 8 to ensure that the liquid medicine smoothly flows into the air chamber 10.

During the use earlier with liquid medicine 7 through syringe or transfusion system from advancing the injection mouth 3 injection or slowly drip into 6 flourishing sap cavity 8 of atomizing bottle, open the oxygen source of being connected with oxygen pipe interface 12 again, oxygen enters into air chamber 10 from oxygen passageway 12 fast, the negative pressure that high flow oxygen formed inhales liquid medicine 7 from air chamber 10 side inlet 9, and upwards spray, impact become superfine vaporific blowout from fog passageway 5 of fog-out behind spacer 11, through extension tube 14 to atomizing face guard 1, see behind the fog again with connecting pipe 2 and trachea cannula or trachea cut open end peg graft together.
