Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a self-lubricating sputum suction tube. Background Art

[0002] A suction tube is a medical device used to suck out secretions or discharges from the respiratory tract. It is often used to help clear sputum from the respiratory tract so that the patient can breathe more easily. Suction tubes are usually made of soft plastic or silicone, with one end connected to a suction machine or manual suction device, and the other end inserted into the patient's mouth or trachea to suck out sputum through negative pressure. Suction tubes are widely used in medical environments such as emergency, surgery, rehabilitation, and intensive care;

[0003] However, existing suction tubes have some problems and shortcomings:

[0004] 1. The existing suction tube has not been treated with low friction, and the patient's poor tube resistance may cause harm;

[0005] 2. Although some suction tubes are equipped with lubricating water bags, medical staff need to hold tweezers to hold the cotton ball with medical lubricant to apply the lubricant. The whole application process takes a long time, and long-term application will waste the patient's respiratory tract cleaning time. Therefore, we propose a self-lubricating suction tube to solve the above problem. Utility Model Content

[0028] The sputum suction tube body 1 includes a tube body main body 11, and a sputum suction port 12 is provided at one end of the tube body main body 11 away from the connecting head 2, and a liquid inlet side cavity 13 is opened on the outer side of the tube body main body 11, and the balloon 3 is fixedly connected to the side of the tube body main body 11 away from the sputum suction port 12, and the connection method of the balloon 3 is generally: bonding, ultrasonic welding, hot melt welding, laser welding, etc.; a side hole 15 is opened on the sputum suction tube body 1 at the position of the balloon 3, and the side hole 15, the balloon 3 and the liquid inlet side cavity 13 are interconnected; the liquid inlet mechanism 5 includes a liquid inlet pipe 51, one end of the liquid inlet pipe 51 is fixedly connected to the outer side of the tube body 11, and one end of the liquid inlet pipe 51 and the liquid inlet side cavity 13 are interconnected; the liquid is transported into the balloon 3 in advance through the liquid inlet pipe 51 of the liquid inlet mechanism 5.

[0029] The end of the liquid inlet side cavity 13 close to the sputum suction port 12 is provided with a melting head structure 14; the end of the liquid inlet side cavity 13 close to the sputum suction port 12 is processed with the melting head structure 14 to prevent the medical lubricating liquid 4 from leaking from the liquid inlet side cavity 13 along the sputum suction tube body 1.

[0030] A one-way valve 52 is fixedly mounted on one end of the liquid inlet pipe 51 away from the pipe body 11 .

[0031] The connector 2 includes a connector body 21, which is fixedly mounted on the end of the tube body 11 away from the sputum suction port 12. A plug 22 is fixedly mounted on the top of the connector body 21. A clinically common vacuum residual control channel 211 is provided in the connector body 21. A needle 221 is movably mounted on the end of the plug 22 away from the connector body 21. The needle 221 corresponds to the position of the balloon 3. A protective plug 222 is movably mounted on the bottom of the end of the plug 22 close to the needle 221. The needle 221 is usually covered by the protective plug 222.

[0033] By arranging a plurality of tiny smooth protrusions 111 (or smooth small grooves) on the portion below the balloon 3 of the suction tube body 1, the smooth small protrusions 111 (or smooth small grooves) greatly reduce the contact area between the suction tube body 1 and the airway, thereby effectively reducing the resistance when the patient end of the suction tube is inserted into the respiratory tract (according to molecular theory and adhesion theory, when the two contact surfaces are elastic materials, the friction force is proportional to the contact area).

[0034] Working principle: When in use, open the paper-plastic bag packaging of the suction tube, take out the suction tube body 1, open the protective plug 222 on the plug 22, and while ensuring that the suction tube body 1 is vertically suspended, press the plug 22 on the connecting head 2 against the balloon 3 pre-filled with medical lubricant 4, press the pressing plate 223 hard, so that the puncture needle 221 contacts and pierces the balloon 3 filled with medical lubricant 4, and the medical lubricant 4 in the balloon 3 flows downward along the suction tube body 1 to moisten the entire suction tube body 1. At the same time, the medical staff uses their hands wearing medical gloves to apply the suction tube body 1 up and down to further moisten the suction tube body 1 evenly, and then the medical staff connects the negative pressure suction device according to the conventional suction tube usage steps to perform the suction operation.
