Description

Artificial Airway Nebulizer

technical field

The utility model relates to an artificial airway atomizer.

Background technique

The artificial airway includes tracheal intubation and tracheotomy. It is an artificial breathing channel established for the rescue and treatment of critically ill patients, and is generally connected to a ventilator to assist breathing. As the patient's condition improves and there is an indication of weaning, we generally try to wean the artificial airway while retaining the artificial airway. the role of Tao.

However, clinically used nebulizers are generally not suitable for such patients who retain tracheal intubation after weaning. The most common common nebulizers in clinical practice are the mask type and the mouth type. There is no nebulizer that matches the artificial airway. It is more common to use the modified mask nebulizer for patients with tracheotomy. That is to say, the mask nebulizer is used to hold the nebulized liquid medicine and connect the high-flow oxygen source to cover the open end of the tracheostomy. , which will bring workload to nurses and at the same time cause the risk of airway drying due to high-flow oxygen inhalation of empty bottles due to leakage of drug solution. In addition, the currently used tracheotomy atomized mask may cause the mask to shift when the patient is slightly moved, and even cause the liquid to be spilled.

Utility model content

The present disclosure provides an artificial airway atomizer, which can achieve the purpose of atomization inhalation that is suitable for both tracheotomy and tracheal intubation patients, and improves patient comfort and nursing safety.

According to a first aspect of the embodiments of the present disclosure, an artificial airway nebulizer is provided, including a sealed nebulizer bottle, and a connecting pipe for delivering the gas atomized by the nebulizer bottle to the artificial airway, and an air outlet of the connecting pipe Match with the air inlet of the artificial airway;

Among them, the atomizing bottle includes:

The air chamber gradually increases in diameter from bottom to top, including the air inlet at the bottom, the liquid inlet at the side, and the air outlet at the top;

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

The liquid-holding cavity surrounds the air chamber, and the diameter of the liquid-holding cavity gradually decreases from bottom to top;

The medicine inlet is communicated with the liquid chamber;

The mist outlet channel is connected to the air outlet at the top of the air chamber to discharge 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 pipe.

Optionally, the mask and the connecting tube are of a one-piece structure.

Optionally, the connecting pipe is a hollow structure.

Optionally, a spacer is fixed in the air chamber, and there is a space between the spacer and the inner wall of the air chamber for the atomized air flow to pass through.

Optionally, the liquid-holding cavity is a funnel-shaped structure.

Beneficial effects of the present disclosure: it is suitable for both tracheotomy and nebulization inhalation of patients with endotracheal intubation, and when the patient changes the body position, phenomena such as drug liquid splashing and artificial airway pulling will not occur, and no oxygen tube will occur. This improves patient comfort and nursing safety; in addition, it can ensure continuous infusion of medicinal liquids and reduce nurses’ workload.

Description of drawings

The present disclosure will be described in further detail below with reference to the accompanying drawings and specific embodiments.

FIG. 1 is a schematic structural diagram of an artificial airway atomizer according to an exemplary embodiment.

Detailed ways

FIG. 1 is a schematic structural diagram of an artificial airway atomizer according to an exemplary embodiment. As shown in FIG. 1 , the atomizer includes a connecting pipe 2 and an atomizing bottle 6. The connecting pipe 2 is connected to the artificial airway to connect the The gas atomized by the atomizing 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 airway, and they can be connected by plugging and unplugging. The tight connection between the nebulizer and the artificial airway solves the problem that the interface between the common nebulizer inhaler and the artificial airway is inconsistent, resulting in the overflow of medicinal liquid mist, causing waste and failing to humidify the airway. The nebulizer is suitable for both tracheotomy and nebulization in intubated patients.

The connecting tube 2 can be connected to the atomizing bottle 6 through an extension tube 14. The extension tube 14 is flexible and has a long length, which can prevent the artificial airway from being pulled when the patient changes position. The connecting tube 2 can be a hollow structure, the function of which is that the gas exhaled from the artificial airway can be dispersed from the hollow to the outside, and the hollow design can facilitate the nurse to perform sputum suction operation on the patient without affecting the patient's atomization inhalation. The connecting pipe 2 is provided with a mask 1. The function of the mask 1 is mainly to prevent the sputum from splashing and keep it clean and hygienic. The mask 1 and the connecting pipe 2 can be of an integrated structure.

The atomizing bottle 6 is a closed structure, including a medicine inlet 3, a mist outlet channel 5, a liquid holding chamber 8, an air chamber 10, an oxygen pipe interface 13, and the like. The diameter of the air chamber 10 gradually decreases from bottom to top, and its longitudinal section is a triangular structure. The bottom of the air chamber 10 is the air inlet, the oxygen pipe interface 13 is connected to the air inlet through the oxygen channel 12, the oxygen pipe interface 13 is used for connecting with the gas source, and the oxygen channel 12 can be arranged along the inner wall of the atomizing bottle 6; The side of the air chamber 10 has a plurality of liquid inlets 9 for the inflow of the liquid medicine 7 in the liquid chamber 8; 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 the extension pipe 14. Connect to discharge the atomized gas. A spacer 11 is fixed in the air chamber 10, and the spacer 11 can be placed horizontally.

The liquid holding cavity 8 surrounds the air chamber 10, and the liquid medicine 7 can be injected into the liquid holding cavity 8 through the medicine inlet 3 on the bottle body. The diameter of the liquid-holding cavity 8 gradually decreases from bottom to top, and can be a funnel-shaped structure.

When in use, first inject or slowly drop the medicinal liquid 7 from the medicine inlet 3 into the liquid chamber 8 of the atomizing bottle 6 through a syringe or an infusion device, and then open the oxygen source connected to the oxygen tube interface 12, and the oxygen is quickly released from the oxygen. The channel 12 enters the air chamber 10, and the negative pressure formed by the high flow oxygen inhales the medicinal liquid 7 from the liquid inlet 9 on the side of the air chamber 10, and sprays it upwards. The channel 5 is sprayed out, and passes through the extension pipe 14 to the atomizing mask 1. After seeing the mist, the connecting pipe 2 is inserted into the open end of the tracheal intubation tube or tracheotomy.
