Description

TECHNICAL FIELD

[0001] The present application relates to medical devices, in particular to a tracheostomy high flow pipeline. BACKGROUND

[0002] Tracheostomy high flow oxygen therapy (THFO) is mainly suitable for: 1. Patients with severe illness and severe hypoxia; these patients need high flow oxygen to alleviate the hypoxia situation due to the severity of hypoxia. Tracheostomy high flow oxygen therapy can provide accurate inhaled oxygen concentration and optimal airway humidification, which helps to improve the hypoxia of the patient. 2. Patients with craniocerebral injury combined with tracheostomy; craniocerebral injury patients often need to use tracheostomy during rescue, but this operation can easily damage the epithelial function of the respiratory tract, cause airway tissue pathology, and increase the degree of hypoxia. Reasonable airway humidification is particularly important for these patients, which can fully humidify the airway, dilute sputum, reduce sputum viscosity, maintain airway cilia movement and clearance function, avoid airway obstruction, and promote patient recovery. 3. Weaning of long-term mechanical ventilation patients; for patients who rely on mechanical ventilation for a long time, tracheostomy high flow oxygen therapy can be used as an auxiliary means during weaning, helping patients gradually adapt to spontaneous breathing. 4. Home oxygen therapy for patients with chronic respiratory failure; for patients with chronic respiratory failure, tracheostomy high flow oxygen therapy can also be used as a home oxygen therapy method to improve the quality of life of patients.

[0003] Tracheostomy high flow oxygen therapy is implemented through a tracheostomy high flow pipeline.

[0004] The structure of the current tracheostomy high flow pipeline is shown in Figures 1-3 , which includes a Y-shaped pipe 10 and a shielding shell 20; the first end of the Y-shaped pipe is used to connect to the tracheostomy cannula of the patient, and the second end is connected to the high flow oxygen source through a threaded hose; the shielding shell is integrally installed at the third end, and is used to block the sputum sprayed by the patient when coughing.

[0005] The disadvantages of the current tracheostomy high flow pipeline are: 1. The connection between the shielding shell and the Y-shaped pipe cannot be disassembled, which not only makes it inconvenient for patients to replace and clean the sputum after coughing, but also can only replace the entire pipeline each time, resulting in high cost, waste of consumables, and difficulty for family members to accept. 2. After the patient coughs out sputum, the sputum will be sprayed on the patient's body or clothes, resulting in sputum everywhere on the patient, which is not only unsightly but also unhygienic, can easily cause infection, and will increase the work of medical staff, requiring the patient's sputum to be wiped and the shield cap to be cleaned from time to time. 3. The shielding shell is made of a blue plastic shell, which cannot observe the properties and amount of the patient's sputum well, and does not play a role in observing the patient's condition in clinical work, which is not conducive to the use of clinical work. CONTENT OF THE INVENTION

[0006] In view of the above problems, this application aims to provide a tracheotomy type high-flow tubing that can attach to the sputum ejected by the subject when coughing and can facilitate the observation of the sputum.

[0007] The tracheostomy-type high-flow tubing of this application includes a Y-shaped tube, the first end of which is used to connect to the patient's tracheostomy cannula, and the second end is connected to a high-flow oxygen source through a threaded hose.

[0009] The sputum-blocking cap includes a tube body and a baffle; both the tube body and the baffle are made of transparent plastic; the first end of the tube body is inserted into the third end of the Y-shaped tube; the baffle is connected to the second end of the tube body by at least two connecting rods, and a predetermined interval is formed between the baffle and the second end of the tube body; multiple elastic hairs are fixedly formed on the inner circumferential surface of the tube body to block and adhere to the sputum expelled when the subject coughs; the multiple hairs are spirally distributed along the inner circumferential surface of the tube body.

[0010] Preferably, the baffle completely covers the second end of the tube body in the axial direction.

[0011] Preferably, the edge of the baffle is folded towards the second end of the tube.

[0012] The tracheostomy-type high-flow tubing of this application can be detachably installed on a Y-shaped tube for easy replacement or cleaning; in the tracheostomy-type high-flow tubing of this application, the Y-shaped tube and the sputum-blocking cap form a transparent structure, making it easy to observe the nature and quality of sputum when it adheres to it; the sputum-blocking cap of the tracheostomy-type high-flow tubing of this application is provided with elastic fine hairs, which are arranged in a spiral shape inside the tube, and can easily adhere the ejected sputum to it.

[0023] The air-cutting type high-flow pipeline of this application will now be described in detail with reference to the accompanying drawings.

[0024] The tracheostomy-type high-flow tubing of this application includes a Y-shaped tube 10, the first end of which is connected to the patient's tracheostomy cannula, and the second end is connected to a high-flow oxygen source via a threaded hose. This is the same as the prior art.

[0025] In this application, the third end of the Y-shaped tube 10 is detachably connected to a phlegm-blocking cap 30.

[0026] The obstructive cap 30 includes a tube body 31 and a baffle 32; both the tube body 31 and the baffle 32 are made of transparent plastic; the first end of the tube body 31 is inserted into the third end of the Y-shaped tube 10; the baffle 32 is connected to the second end of the tube body 31 by at least two connecting rods 34, and forms a predetermined interval between the baffle and the second end of the tube body 31; multiple elastic bristles 34 are fixedly formed on the inner circumferential surface of the tube body 31, similar to the bristles of a toothbrush, but arranged more sparsely to ensure unobstructed breathing for the subject. The bristles can also be transparent fibers. The fine hairs are used to block and adhere to the sputum expelled when the subject coughs. The fine hairs 34 can be arranged at an angle, with the root of each fine hair close to the first end of the tube and the head close to the second end of the tube. The multiple fine hairs 34 are spirally distributed along the inner circumferential surface of the tube 31. In this way, on a cross-section perpendicular to the axial direction of the tube 31, the fine hairs are not distributed across the entire cross-section of the tube, but only cover a predetermined angle of the cross-section, such as 30 degrees. This ensures that there is a sufficiently large airflow space in each cross-section. However, the multiple cross-sections are staggered in the circumferential direction at a certain angle. In this way, when viewed in the axial direction, the entire tube is covered by fine hairs, so that sputum can be well adhered or stuck.

[0027] The baffle 31 completely covers the second end of the tube 31 in the axial direction of the tube 31, so that if sputum escapes from the tube, it can be blocked and adhered by the baffle. The edge of the baffle 32 is folded towards the direction of the second end of the tube 31.

[0028] In use, the tracheostomy high flow tube of the application is installed on the tracheostomy cannula; when the patient coughs, the sputum is blocked and adhered by the fine hair layer in the tracheal tube, and is not easy to spray outside; since the tube and the baffle are both transparent plastic, the sputum adhered in the tube can be easily observed. Since the tracheostomy high flow tube of the application is detachably installed on the tracheostomy cannula, it can be taken out at any time for flushing with clean water, or a new tracheostomy high flow tube can be directly replaced.
