[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] Reference Figure 1A side suction anti-damage sputum suction tube comprises a tube body 1, the top of the tube body 1 is provided with two first liquid inlets 9, the top of the tube body 1 is rotatably connected with a partition plate 2, the side wall of the partition plate 2 is provided with two liquid inlet holes 6, the liquid inlet holes 6 are adapted to the first liquid inlet 9, the top of the tube body 1 is slidably provided with a card block 4, the card block 4 is engaged with the bottom of the partition plate 2; when the tube body 1 is used to suction sputum from the patient's throat, the tube body 1 is continuously penetrated into the patient's throat, and then Then, the sputum is sucked into the tube body 1 through the first liquid inlet 9 at the top of the tube body 1. When the tube body 1 is pulled out, in order to prevent the sputum in the tube body 1 from flowing back and causing the sputum to enter other parts of the body and cause cross infection, when the tube body 1 is pulled out, the traction rope 5 is pulled to drive the block 4 to move, so that the block 4 is separated from the partition plate 2. Under the action of the torsion spring 3, the partition plate 2 rotates, so that the first liquid inlet 9 is separated from the liquid inlet hole 6, and the top of the tube body 1 is sealed to prevent the sputum from flowing back when the tube body 1 is pulled out.

[0022] As a preferred technical solution of this embodiment, a torsion spring 3 is fixedly connected to the bottom of the partition plate 2, and the other end of the torsion spring 3 is fixedly connected to the tube body 1, and a traction rope 5 is fixedly connected to the bottom end of the clamping block 4. The end of the traction rope 5 away from the clamping block 4 passes through the side wall of the tube body 1 and is fixedly connected to a traction block 10, and the traction block 10 is engaged with the side wall of the tube body 1. A limiting block 7 is fixedly connected to the bottom of the partition plate 2, and a limiting groove 8 is provided inside the top end of the tube body 1, and the limiting block 7 is slidably arranged inside the limiting groove 8; when the tube body 1 is pulled out, the traction rope 5 is driven by pulling the traction block 10, so that the clamping block 4 and the partition plate 2 are separated, and the partition plate 2 rotates under the action of the torsion spring 3. When the partition plate 2 rotates, the limiting block 7 slides from one end of the limiting groove 8 to the other end, just separating the liquid inlet hole 6 on the partition plate 2 from the first liquid inlet 9 at the top end of the tube body 1, and sealing the first liquid inlet 9 to avoid cross infection.

[0023] As a preferred technical solution of this embodiment, a second liquid inlet 14 is opened on both side walls of the top of the tube body 1; the sputum in the patient's throat is absorbed through the second liquid inlet 14, increasing the liquid absorption range of the tube body 1, thereby improving the liquid absorption effect.

[0024] As a preferred technical solution of this embodiment, a connector 11 is fixedly installed at one end of the tube body 1; the existence of the connector 11 makes the suction operation more convenient, and medical staff can quickly and easily connect the suction tube to the suction equipment, thereby improving work efficiency.

[0025] As the preferred technical solution of this embodiment, a side port 12 is fixedly installed on the side wall of the joint 11, and a groove 13 is provided at the top of the side port 12; the side port 12 can be used as a switch to control the negative pressure of the suction tube. When the side hole is closed, the front end nozzle of the suction tube will generate negative pressure suction for sucking sputum. Conversely, when the side hole is in an open state, the negative pressure suction of the front end nozzle will disappear. Such a design enables medical staff to flexibly control the negative pressure state of the suction tube as needed. Secondly, the opening of the side port 12 also helps to protect the patient's respiratory mucosa. During the insertion of the suction tube, if the tube cavity is always in a negative pressure state, the front end nozzle may suck the patient's airway mucosa, thereby causing adverse reactions such as coughing, and may even cause damage. The groove 13 makes the top of the side port 12 fit more closely to the human thumb, which is easy to control.

[0026] As a preferred technical solution of this embodiment, a soft contact 15 is fixedly installed on the top of the tube body 1; the soft contact 15 is used to protect the patient's oral cavity to avoid damage to the patient's oral cavity during the suction process.

[0027] The general working principle of the utility model is as follows: when suctioning sputum with a sputum suction tube, the joint of the sputum suction tube is connected to the sputum suction device, and then the tube body is deeply inserted into the patient's throat. During the process of the tube body being deeply inserted, the side opening is pressed with the thumb to prevent the tube cavity from being always in a negative pressure state. The front end of the tube opening may suck the patient's airway mucosa, thereby causing adverse reactions such as coughing. After suctioning sputum in the patient's throat is completed, when the tube body is retracted, the traction block is pulled, and the traction rope is driven by the traction block to pull the card block out of the partition plate. The partition plate rotates under the action of the torsion spring. When the partition plate rotates, the limit block slides from one end of the limit groove to the other end, just separating the liquid inlet hole on the partition plate from the first liquid inlet at the top of the tube body, sealing the first liquid inlet to avoid cross infection. During the process of retrieving the tube body, the sputum suction device is always in an open state, and the second liquid inlet always sucks liquid into the tube, and the second liquid inlet is at a certain distance from the bottom end. The refluxed sputum gathers at the lowest end, so that the sputum will not be discharged from the second liquid inlet.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
