Description

Technical Field

[0001] This utility model relates to a nebulizer, specifically a nebulizer for patients with endotracheal intubation. Background Technology

[0002] Respiratory therapy is of great significance in promoting effective sputum expectoration and reducing the occurrence of complications in patients with long-term intubation, and nebulized inhalation is an important part of this process.

[0003] Oxygen nebulization inhalation is a method that uses a high-speed airflow of oxygen to atomize medication into fine mist particles, which are then inhaled into the respiratory tract. It plays an important role in humidifying the airways, preventing and controlling respiratory infections, and improving lung ventilation.

[0004] In existing technologies, oxygen nebulization inhalation is mostly achieved using oxygen nebulizer masks, which include an oxygen connecting tube, a nebulizer, and a mask. One end of the oxygen connecting tube is connected to the output of the oxygen device, and the other end is connected to the air inlet of the nebulizer. The air outlet of the nebulizer is connected to the mask.

[0005] However, existing masks are not compatible with endotracheal tubes. During nebulization therapy, they are usually placed over the endotracheal tube and cannot be secured. In addition, the outlet of some nebulizers is located on the side wall of the device, which makes the nebulizer prone to tipping over due to factors such as coughing or agitation by the patient, resulting in the leakage and waste of medication. Furthermore, the opening of the mask is too large, which causes a large amount of atomized drug particles to be sprayed into the air. When the patient inhales, the amount of atomized drug particles is greatly reduced, affecting the effectiveness of nebulization therapy. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a nebulizer for endotracheal intubation patients, which is suitable for nebulized inhalation by endotracheal intubation patients and improves the nebulization treatment effect of patients.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] A nebulizer for intubated patients includes an oxygen connection tube and a nebulizer; its distinguishing feature is that the nebulizer also includes a retractable tube and a three-way valve. The nebulizer includes a medicine cup, a lid, a nozzle, and a nebulizer core. The medicine cup is used to hold liquid medication, and the lid covers the mouth of the medicine cup. The nozzle is located at the central axis of the medicine cup, with one end extending beyond the lower end of the medicine cup. The nebulizer core is disposed inside the medicine cup and fitted over the other end. The upper ends of the nebulizer core and the nozzle have concentric nozzles located above the nozzles of the nebulizer core. The device features a frustum integrated with a cup lid. Above the cup lid is a vertically upward-facing vent that connects to the medicine cup. One end of the oxygen connector connects to the vent of an oxygen device, and the other end connects to the end of the nozzle outside the medicine cup. The vent of the cup lid connects to one end of a retractable tube, and the other end of the retractable tube connects to the main pipe of a three-way connector. One branch of the three-way connector has a connector for connecting to an endotracheal tube, and the other branch has a ventilation mesh.

[0009] Furthermore, a humidification liquid interface communicating with the medicine cup is provided on the side wall of the medicine cup, and a protective cap is provided at the opening of the humidification liquid interface, and the protective cap is connected to the humidification liquid interface through a connecting rope.

[0010] The beneficial effects of this utility model are:

[0011] The nebulizer for intubated patients provided by this utility model involves connecting an oxygen supply tube to an oxygen device and connecting the connector to the patient's endotracheal tube. During nebulization, the nebulizer atomizes the gas, which is then transmitted from the retractable tube to the connector, facilitating the patient's inhalation of the atomized gas. When the patient exhales, the exhaled gas is expelled through the ventilation mesh without affecting normal breathing. Compared to using a face mask, this nebulizer is more suitable for intubated patients, allowing them to inhale most of the atomized gas during inhalation, with only a small portion dissipating into the air through the ventilation mesh, thus improving the patient's treatment effectiveness.

[0019] The present invention will now be described in conjunction with the accompanying drawings. The specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention. Various modifications and improvements to the technical solutions of the present invention made by those skilled in the art without departing from the spirit of the present invention should fall within the protection scope of the present invention.

[0020] like Figures 1 to 6 As shown, the nebulizer for endotracheal intubation patients in this embodiment includes an oxygen connection tube 1, a nebulizer 2, a retractable tube 3, and a three-way tube 4.

[0021] The atomizer 2 includes a medicine cup 21, a cup lid 22, a nozzle 23, and an atomizing core 24. The medicine cup 21 is used to hold the medicine liquid. The cup lid 22 covers the mouth of the medicine cup 21 and is connected to the medicine cup by a thread. The nozzle 23 is located at the central axis of the medicine cup 21, with one end extending outside the lower end of the medicine cup 21. The atomizing core 24 is located inside the medicine cup 21 and is sleeved on the outside. The upper ends of the atomizing core 24 and the nozzle 23 have concentric spray holes 25. A frustum 26 is located above the spray holes 25 of the atomizing core 24 and is integrated with the cup lid 22. An air outlet 221 that communicates with the medicine cup 21 and faces vertically upwards is located above the cup lid 22.

[0022] One end of the oxygen connecting tube 1 is connected to the outlet of the oxygen device, and the other end is connected to the end of the nozzle 23 located outside the medicine cup 21. The outlet 221 of the cup cover 22 is connected to one end of the retractable tube 3, and the other end of the retractable tube 3 is connected to the main pipe of the three-way tube 4. The retractable tube 3 can be extended or shortened to improve the adaptability of the nebulizer. One branch pipe of the three-way tube 4 is provided with a connector 5 for connecting to the endotracheal tube port, and the other branch pipe is provided with a ventilation mesh 6. The ventilation mesh 6 can both prevent dust and allow the patient to exhale.

[0023] The nebulizer works as follows: When in use, unscrew the cup cap 22, pour a certain amount of liquid medicine into the medicine cup 21, tighten the cup cap 22, and connect the nozzle 23 to the oxygen connection tube 1. The oxygen generated by the oxygen device enters the medicine cup 21 through the nozzle 23. Using the Venturi jet principle, the liquid medicine is drawn up and sprayed onto the frustum 26 with the gas. The atomized particles are broken up. Some of the fine atomized particles are sprayed out from the air outlet 221 with the gas and supplied to the patient, while some larger particles fall to the bottom of the medicine cup 21. This process is repeated until all the atomized liquid medicine is sprayed out, achieving the therapeutic effect.

[0024] In use, this invention connects the oxygen connection tube 1 to the oxygen device and the connector 5 to the patient's endotracheal tube. During nebulization, the nebulizer 2 atomizes the gas, which is then transmitted from the retractable tube 3 to the connector 5, facilitating the patient's inhalation of the atomized gas. When the patient exhales, the exhaled gas is expelled through the ventilation mesh, without affecting the patient's normal breathing. Compared to using a face mask, this nebulizer is more suitable for patients with endotracheal tubes. During inhalation, the patient can inhale most of the atomized gas, with only a small portion dissipating into the air through the ventilation mesh 71, thus improving the patient's treatment effect. Because the air outlet 221 is vertically upward and the retractable tube 3 is also in a vertical position during use, the medication in the nebulizer 2 is less prone to backflow or tipping.

[0025] In addition, a humidification fluid interface 7 is provided on the side wall of the medicine cup 21, communicating with the medicine cup 21. A protective cap 71 is provided at the opening of the humidification fluid interface 7, and the protective cap 71 is connected to the humidification fluid interface 7 via a connecting rope 72. An infusion bottle containing humidification fluid can be connected through the humidification fluid interface 7. The infusion bottle is connected to the humidification fluid interface 7 via an infusion tube, allowing the humidification fluid to drip into the medicine cup 21 along the infusion tube. Then, using the principle of nebulization, the humidification fluid mixes with oxygen to humidify the oxygen, and the humidified oxygen is delivered to the patient's airway to moisten the airway and prevent airway dryness, as well as sputum adhesion, crusting, and airway blockage. When the humidification fluid interface 7 is not in use, the protective cap 71 closes its opening.

[0026] In summary, this utility model's nebulizer for intubated patients integrates oxygen delivery, nebulization, and humidification into one device, solving the problem of commonly used clinical devices having only one function—either oxygen delivery or nebulization—and increasing workload and departmental consumables each time treatment is switched. Furthermore, this device is less prone to medication spillage during nebulization, ensuring effective nebulized inhalation and maximizing drug efficacy. In addition, this utility model can be used not only for intubated patients but also for tracheostomy patients.
