Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular relates to an artificial nose connector capable of automatically sucking sputum. Background Art

[0002] An artificial nose, also known as a heat and moisture exchanger, is often used in patients with tracheotomy. It simulates the function of the nose, transforming the open airway formed by tracheotomy into a closed airway. It has the functions of ensuring sufficient humidification of the gas, reducing pollution, filtering bacteria, preventing lung infections, and improving the effect of oxygen therapy.

[0003] During the use of artificial noses in tracheotomy patients, there was a problem of patients coughing up sputum and contaminating the artificial nose, causing blockage of the artificial nose. Utility Model Content

[0004] The utility model aims to provide an artificial nose connector which can automatically suck sputum. The connector is connected between the artificial nose and a tracheotomy tube. The sputum coughed up by the patient can be disposed of by the connector to prevent the sputum from entering the artificial nose and causing the artificial nose to be contaminated or blocked.

[0005] The utility model is realized by the following technical solutions:

[0006] An artificial nose connector capable of automatically suctioning sputum comprises a three-way tube body, one end of which is a trachea connection end, which is used to connect a tracheotomy tube on a patient; one end of which is an artificial nose connection end, which is used to connect an artificial nose; and the other end of which is a sputum storage tank connection end, which is connected to a sputum storage tank;

[0007] A one-way valve is installed at the connection end of the sputum storage tank inside the three-way pipe body, and the one-way valve allows sputum to flow from the inside of the three-way pipe body to the inside of the sputum storage tank in one direction, thereby preventing the sputum in the sputum storage tank from flowing back into the three-way pipe body;

[0008] A negative pressure joint is provided at the bottom of the sputum storage tank, and the negative pressure joint is connected to a negative pressure suction device through a negative pressure hose;

[0009] When the connector is in use, its trachea connecting end is connected to the tracheotomy tube on the patient, the artificial nose is connected to the artificial nose connecting end, and the negative pressure connector on the sputum storage tank is connected to the negative pressure suction device through a negative pressure hose. When the patient coughs up sputum, the coughed-up sputum enters the three-way tube body. Due to the pressure generated by the cough, the pressure inside the three-way tube body also increases accordingly. Since the sputum storage tank is under negative pressure and the gravity of the sputum is applied, the one-way valve opens, and the sputum in the three-way tube body flows into the sputum storage tank and is sucked away by the negative pressure, thereby preventing the sputum in the three-way tube body from entering the artificial nose and causing the artificial nose to be contaminated or blocked.

[0010] Furthermore, the sputum storage tank connecting end of the three-way pipe body is integrally formed with the sputum storage tank.

[0011] Furthermore, the three-way tube body is a T-type three-way tube structure or a Y-type three-way tube structure; when the patient takes a 30° to 45° supine position, the sputum storage tank connection end is located at the lower side of the artificial nose connection end, which can facilitate the sputum coughed into the three-way tube body to reach the sputum storage tank connection end.

[0012] Furthermore, the three-way pipe body and the sputum storage tank are both made of transparent plastic, which is light in weight, low in cost, and can facilitate observation of the internal conditions.

[0013] Furthermore, the negative pressure connector is a pagoda-shaped interface, which can be quickly connected and disconnected with the negative pressure hose, and the connection structure is stable.

[0014] Furthermore, a suction joint connected to the interior of the three-way tube body is provided on the three-way tube body between the artificial nose connecting end and the sputum storage tank connecting end, the central axis of the suction joint is colinear with the central axis of the trachea connecting end, and a detachable suction piston for blocking the internal channel of the suction joint is installed at the end of the suction joint; when the patient cannot cough up sputum and needs artificial suction, the suction piston on the suction joint can be removed, and the suction tube can be inserted from the suction joint into the three-way tube body for artificial suction, and the suction piston can be installed to block the suction joint after the artificial suction is completed.

[0015] Furthermore, a connecting belt is provided between the sputum suction piston and the sputum suction connector, and two ends of the connecting belt are fixedly connected to the sputum suction piston and the sputum suction connector respectively, which can prevent the sputum suction piston from being lost after the sputum suction piston is removed.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] The connector can be transitionally connected between the artificial nose and the tracheostomy tube of a tracheotomy patient to prevent sputum from entering the artificial nose when the patient coughs up sputum, causing the artificial nose to be contaminated or blocked. When in use, the tracheal connecting end of the three-way tube body is connected to the tracheostomy tube on the patient, the artificial nose is connected to the artificial nose connecting end, and the negative pressure connector on the sputum storage tank is connected to a negative pressure suction device through a negative pressure hose. When the patient coughs up sputum, the coughed-up sputum enters the three-way tube body. Due to the pressure generated by the cough, the pressure inside the three-way tube body also increases. Since the sputum storage tank is under negative pressure and the gravity of the sputum is applied, the one-way valve opens, and the sputum in the three-way tube body flows into the sputum storage tank and is sucked away by the negative pressure. In this way, the sputum in the three-way tube body can be prevented from entering the artificial nose, causing the artificial nose to be contaminated or blocked, thereby extending the use time of the artificial nose, reducing the economic burden on patients, reducing the workload of nurses, reducing waste of resources, reducing the generation of medical waste, and promoting low-carbon care.
