Description

Technical Field

[0001] This application relates to the field of nebulization therapy technology for tracheostomy patients, and more particularly to an umbrella-shaped flow guide device for tracheostomy patients. Background Technology

[0002] A tracheostomy is an artificial airway established clinically to relieve upper airway obstruction, maintain airway patency, facilitate the clearance of lower respiratory tract secretions, or facilitate long-term mechanical ventilation. After the procedure, a tracheostomy cannula (or simply "tracheostomy tube") is placed in the patient's neck. During nebulized drug administration, the aerosol is delivered into the patient's airway through the tracheostomy tube.

[0003] However, the following common and challenging problems exist in the daily care and life of tracheostomy patients: 1. Splashing and contamination of respiratory secretions lead to maceration damage to the skin, and the epidermis softens and erodes in a long-term moist environment (studies show that the skin barrier function decreases by 70% after 4 hours of continuous moisture); 2. After the nebulized aerosol liquefies, it soaks the gauze dressing, and the moist environment can promote bacterial colonization (such as a 3-fold increase in the infection rate of Pseudomonas aeruginosa), which may lead to inflammation of the tracheostomy site in patients. Utility Model Content

[0004] This invention provides an umbrella-shaped drainage device for tracheostomy patients. This umbrella-shaped drainage device has the advantage of draining and collecting respiratory secretions or aerosol liquid after drainage, avoiding soaking the gauze dressing and causing medical staff to change it frequently.

[0005] The objective of this utility model is achieved through the following technical solution: An umbrella-shaped flow guiding device for tracheostomy patients, characterized in that it includes an atomizing hood, a tracheal cannula, and a flow guiding hood; the flow guiding hood includes a flow guiding plate and a liquid collection frame, the flow guiding plate has a hole in the middle for the tracheal cannula to pass through, the atomizing hood and the flow guiding plate are detachably connected, and the upper opening of the tracheal cannula is located in the chamber formed by the atomizing hood and the flow guiding plate; the liquid collection frame and the flow guiding plate are fixed, and the atomizing hood has a liquid outlet on the side facing the liquid collection frame.

[0006] Preferably, an air intake plate is fixedly installed inside the atomizing hood, the air intake plate is inclined and is located at the upper opening of the air tube sleeve.

[0007] Preferably, the liquid collection frame is provided with a drainage tube.

[0008] Preferably, the tracheostomy tube has a fixation extension piece at the side end that fits the skin.

[0009] Preferably, the atomizing cover has fixing blocks on both sides, and the fixing blocks have fixing holes, with straps wrapped and fixed inside the fixing holes.

[0010] Preferably, the upper end of the atomizing cover is provided with a rotating ring, and the rotating ring is equipped with an atomizing air pipe.

[0011] Preferably, the connection between the liquid collection frame and the guide plate is inclined, and the connection between the liquid collection frame and the drainage tube is located at the bottom of the inclined surface.

[0012] Compared with the prior art, the advantages or beneficial effects of the technical solution of this application include: 1. Umbrella-shaped flared design: The nebulizer forms a physical barrier above the tracheostomy tube. The angle of the umbrella surface accurately guides the secretions sprayed during coughing or suctioning to the collection container (liquid collection frame) below, with an interception efficiency of >90%, which greatly reduces the risk of environmental pollution and cross-infection.

[0013] 2. Conical collection funnel (collection frame): The collection frame adopts a scientific tilt angle of 15°-20°, and uses gravity and airflow inertia to achieve zero retention of secretions, with a collection efficiency of over 95% (the actual collection rate when the cough splash volume is 3-5ml).

[0014] 3. Improve patient treatment experience: The gauze dressing around the tracheostomy cannula is less likely to get wet, which not only reduces the workload of medical staff, but also ensures the hygiene of the tracheostomy site and avoids skin ulceration or infection.

[0017] The following detailed description of the embodiments of this application, in conjunction with the accompanying drawings, will provide a thorough understanding of how this application uses technical means to solve technical problems and achieve corresponding technical effects, enabling its implementation. The embodiments of this application and the various features within them can be combined with each other without conflict, and all resulting technical solutions are within the protection scope of this application.

[0018] It should be clearly stated that the embodiments described below are merely some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0019] Example 1: This example provides a detailed explanation of the scheme for simulating a breeding farm: like Figures 1-4 As shown, an umbrella-shaped flow guiding device for tracheostomy patients is characterized by comprising a nebulizer 3, a tracheal cannula 8, and a flow guiding hood. The flow guide includes a flow guide plate 6 and a liquid collection frame 11. The flow guide plate 6 has a hole in the middle for the air tube sleeve 8 to pass through. The atomizing cover 3 and the flow guide plate 6 are detachably connected. The upper opening of the air tube sleeve 8 is located in the chamber formed by the atomizing cover 3 and the flow guide plate 6. The liquid collection frame 11 and the flow guide plate 6 are fixed. The atomizing cover 3 has a liquid outlet hole 10 on the side facing the liquid collection frame 11.

[0020] The atomized medication, after passing through the liquefied droplets, or secretions flowing out of the tracheostomy tube, can be blocked by the umbrella-shaped atomizing hood 3 and then converge onto the guide plate 6. For example... Figure 2 As shown, when the liquid accumulates on the guide plate 6, it will flow out through the outlet hole 10 until it enters the collection frame 11 and is collected. The gauze dressing is placed around or at the bottom of the guide plate 6. When the liquid is drained out in time, it will not flow directly onto the gauze dressing, thus avoiding skin and bacterial infections caused by the gauze dressing getting wet.

[0021] like Figure 3 As shown, an air intake plate 7 is fixedly installed inside the atomizing hood 3. The air intake plate 7 is inclined and is located at the upper opening of the air tube sleeve 8.

[0022] The function of the air intake plate 7 is to collect the mist left from the nebulizer tube 1 and surround it near the opening of the tracheostomy tube 8, so that it can effectively enter the patient's airway. Without the air intake plate 7, the mist may liquefy upon encountering the nebulizer hood 3, which not only wastes the medication, but also causes choking when water droplets drip into the patient's airway.

[0023] like Figure 1 and Figure 2 As shown, the collection frame 11 is equipped with a drainage tube 12. The drainage tube 12 can be connected to a negative pressure suction device to promptly draw the water droplets accumulated on the collection frame 11 to the outside, thus preventing the gauze dressing from getting wet.

[0024] like Figure 3 As shown, the tracheostomy tube 8 has a fixation extension piece 9 at its side end that fits into the skin. The fixation extension piece 9 can be made of silicone material and fits into the patient's skin to provide fixation.

[0025] like Figure 2 As shown, the two ends of the atomizing cover 3 are provided with fixing blocks 4, and fixing holes are provided on the fixing blocks 4. Straps 5 are wrapped and fixed in the fixing holes.

[0026] like Figure 3 As shown, the upper end of the atomizing cover 3 is provided with a rotating ring 2, and the rotating ring 2 is equipped with an atomizing air pipe 1.

[0027] like Figure 3 As shown, the connection between the liquid collection frame 11 and the guide plate 6 is an inclined plane, and the connection between the liquid collection frame 11 and the drainage pipe 12 is located at the bottom of the inclined plane.

[0028] Example 2: Postoperative secretion drainage care Scenario: The patient underwent radical laryngectomy and tracheotomy on the 3rd day post-surgery. The patient had excessive sputum secretion (30ml per day) and frequent coughing, which caused the tracheotomy dressing to be soaked and changed ≥8 times per day.

[0029] Device Application 1. Installation Insert the tracheostomy tube 8 into the tracheostomy opening, attach the silicone fixation extension piece 9 to the neck skin, insert the guide plate 6 into the base of the tube, align the liquid outlet 10 with the inclined surface of the liquid collection frame 11, connect the atomizing hood 3 to the guide plate 6 via a buckle, and secure the strap 5 around the neck via the fixing block 4. 2. Flow diversion effect When the patient suddenly coughs violently, the secretions are sprayed onto the inner wall of the nebulizer hood 3. The liquid flows along the 15° inclined guide plate 6 through the outlet hole 10 into the collection frame 11. The nurses observe through the transparent collection frame 11 that 2.8 ml of sputum is collected in a single instance. 3. Clinical benefits The gauze dressing was kept dry for 24 hours (the control group was soaked an average of 6.2 times / day), the redness and swelling around the tracheostomy subsided (local humidity decreased to 45%), and the nursing time was reduced from an average of 87 minutes per day to 22 minutes. Example 3: Application of Synchronous Nebulization Therapy Scenario: The patient has COPD complicated by lung infection and needs budesonide nebulization treatment 4 times a day through the tracheostomy. With traditional nebulizers, 50% of the drug solution is deposited on the gauze.

[0030] Device Application 1. Atomization configuration The atomizing ventilation tube 1 is connected to the rotating ring 2, which can be adjusted 360°. The air guide plate 7 guides the drug mist to the inlet of the air tube sleeve 8. 2. Dual-Effect Management While the patient coughs during nebulization, the condensed liquid from the nebulizer mixes with the sputum. The liquid is intercepted by the guide plate 6 and flows into the collection frame 11 via the inclined surface. The drainage tube 12 is connected to an external negative pressure device (-100mmHg) to continuously remove the liquid. 3. Technological advantages Improved drug utilization: The amount of drug residue recovered from the sputum culture cup was reduced by 82% (compared to traditional gauze adsorption). Treatment safety: Airway plate 7 prevents droplets from falling directly into the airway (fiberoptic bronchoscopy shows dry airway mucosa). Easy to operate: Samples are taken directly through the drainage tube 12 during nebulization and sent for testing (Pseudomonas aeruginosa was detected).
