Description

Technical Field

[0001] The utility model relates to the field of sputum suction equipment, in particular to a sputum suction device capable of preventing mucosal damage. Background Art

[0002] The respiratory department is a department that examines and treats respiratory diseases. It is a traditional and important clinical secondary department of the internal medicine system. The respiratory department mainly deals with diseases of the trachea, bronchi, alveoli, blood vessels, pleura and other parts of the body. These diseases include but are not limited to upper respiratory tract infections, lower respiratory tract infections, obstructive airway diseases, diffuse interstitial diseases and pleural diseases.

[0003] At present, when treating patients with respiratory diseases in the respiratory department, a suction device is usually used to suction the patients. The existing suction device is mainly composed of a suction tube and a negative pressure device. The principle is to quickly and safely suck out sputum by negative pressure suction. However, the existing suction device is usually composed of a negative pressure suction device, a connecting tube and a suction hose. When the patient needs to be suctioned through the suction device, the sputum is suctioned through the suction hose provided on the negative pressure suction device. First, the suction hose needs to be inserted into the patient's respiratory tract to suction the patient. The suction hose currently provided on the negative pressure suction device needs to be inserted into one end of the respiratory tract. Since the front end of the suction hose is designed to be relatively flat, sometimes the mucosal tissue may be damaged to a certain extent during the process of inserting the suction hose into the patient's respiratory tract, which increases the patient's pain and the difficulty of operation for medical staff.

[0004] Therefore, it is necessary to provide a new sputum suction device that prevents mucosal damage to solve the above technical problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a sputum suction device which can prevent mucosal damage.

[0006] The utility model provides a sputum suction device for preventing mucosal damage, comprising a negative pressure sputum suction device, a connecting pipe and a sputum suction hose. The connecting pipe and the sputum suction hose are movably connected to the top of a storage tank arranged on the negative pressure sputum suction device through a connecting device, and one end of the connecting pipe away from the storage tank is connected to the top of the negative pressure sputum suction device, one end of the sputum suction hose away from the storage tank is fixedly connected to a plurality of rubber protective rings, one end of the sputum suction hose away from the rubber protective ring is fixedly connected to the connecting hose, and through holes for sputum suction are provided on both sides of the connecting hose, one end of the connecting hose away from the sputum suction head of the hose is fixedly connected to the sputum suction head, and the cross-sectional shape of the sputum suction head is spherical.

[0007] Preferably, the connecting device includes a connecting block, a sliding block and a plurality of elastic parts, the connecting block is fixedly connected to the outer surface of the feed pipe arranged on the top of the storage tank, and a threaded groove is opened on the top of the connecting block, a movable ring is threadedly connected inside the threaded groove, and the movable ring is fixedly connected to the bottom of the suction hose, the sliding block is slidably connected to the inner wall of the through hole opened inside the threaded groove, and one end of the sliding block is located on the inner wall of the groove opened on the feed pipe, the side wall of the sliding block is fixedly connected to the limiting plate, one end of a plurality of the elastic parts is fixedly connected to one side of the limiting plate, and the end of the elastic part away from the limiting plate is fixedly connected to the inner wall of the groove opened in the connecting block.

[0008] Preferably, the elastic member is a spring, one end of the spring is fixedly connected to one side of the limiting plate, and one end of the spring away from the limiting plate is fixedly connected to the inner wall of the groove formed in the connecting block.

[0009] Preferably, the through holes formed on both sides of the connecting hose are circular holes, rectangular holes, cross holes, or special-shaped holes.

[0010] Preferably, the connecting tube, the suction hose, the rubber protective ring, the connecting hose and the suction head are all made of medical-grade plastic material.

[0011] Preferably, a switch is provided on the negative pressure sputum suction device, and a handle is fixedly connected to the top of the negative pressure sputum suction device.

[0012] Preferably, the outer surfaces of the rubber protective ring, the connecting hose and the sputum suction head are covered with protective covers.

[0013] Compared with the related art, the sputum suction device for preventing mucosal damage provided by the utility model has the following beneficial effects:

[0014] 1. Through the provided sputum suction hose, rubber protective ring, connecting hose and sputum suction head, when it is necessary to use the negative pressure sputum suction device to suction the patient, firstly, the protective cover provided on the rubber protective ring, the connecting hose and the sputum suction head needs to be removed, and then the spherical sputum suction head is slowly inserted into the patient's respiratory tract, and then the switch provided on the negative pressure sputum suction device is turned on, and the vacuum pump inside the negative pressure sputum suction device is started through the switch, and sputum is suctioned through the vacuum pump, the connecting tube and the sputum suction hose. This device reduces the probability of certain damage risk to the mucosal tissue in the process of inserting the sputum suction hose into the patient's respiratory tract due to the relatively flat design of the front end of the sputum suction hose, and reduces the patient's pain and the difficulty of operation for medical staff.

[0015] 2. By setting up the connecting device, when the suction hose or the connecting tube needs to be disassembled, this device reduces the difficulty and time of operation and reduces the probability of error. BRIEF DESCRIPTION OF THE DRAWINGS
