[0018] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] An improved sputum suction device, combined with Figure 1 to Figure 2 As shown, it includes a suction chamber 1, one side of the suction chamber 1 is connected to a negative pressure tube 2, and the side opposite to the negative pressure tube 2 is connected to a suction tube 11 for suctioning sputum from patients. A sputum bag 9 is provided at the bottom end of the suction chamber 1 for collecting the sucked sputum.

[0020] A negative pressure connector 4 is provided at the end of the negative pressure tube 2, to which a negative pressure machine 20 is connected for providing negative pressure. The negative pressure tube 2 can also be connected to the negative pressure outlet on the wall of the ward through the negative pressure connector for negative pressure suction.

[0021] The negative pressure pipe 2 is provided with a pressure gauge 5 and a negative pressure regulating valve 3. The pressure gauge 5 is used to indicate the negative pressure, and the negative pressure regulating valve 3 is used to adjust the negative pressure.

[0022] A three-way valve 12 is provided at the end of the suction tube 11. One port of the three-way valve 12 is provided with a suction hose 17 through a connector 15 for extending into the patient's mouth to suction sputum. The connector 15 of the other port of the three-way valve 12 is provided with a saline tube 13, and a physiological saline bag 14 is connected to the saline tube 13.

[0023] A dilution hose 18 is arranged inside the sputum suction hose 17, and the rear end of the dilution hose extends out of the sputum suction hose 17. The end of the dilution hose 18 is connected to another saline tube 13 of the physiological saline bag 14 through a connector. The two saline tubes on the physiological saline bag are respectively provided with saline regulating valves 16, which are respectively used to adjust the water output of the physiological saline. The physiological saline enters the patient's body through the dilution hose to dilute the thick sputum in the respiratory tract and lungs, making it easier to suck out the sputum. The other way is to change the connecting pipeline of the three-way valve, and the sputum suction tube 11 is flushed through the saline tube to prevent the sputum from sticking to the inner wall of the sputum suction tube.

[0024] A positioning block 19 is provided on the sputum suction hose 17 to position the length of the sputum suction hose extending into the patient's body to avoid physical discomfort to the patient due to the hose extending too long into the patient's body.

[0025] A filter screen 8 is vertically arranged in the suction chamber 1, which divides the suction chamber into two chambers, wherein the outlet of the negative pressure tube 2 is located in one chamber, and the suction tube 11 and the outlet connected to the sputum bag 9 are located in another chamber, thereby isolating the negative pressure tube and the suction tube to prevent the sucked sputum from entering the negative pressure tube.

[0026] One-way valves are provided at the connections between the sputum suction chamber 1 and the negative pressure tube 2, the sputum bag 9 and the sputum suction tube 11 to prevent sputum from flowing back.

[0027] The sputum bag 9 is provided with a scale value 10 for indicating the amount of sputum sucked out.

[0028] Hanging holes 7 are provided at the top of the suction chamber 1 and the saline bag 14, which are convenient for hanging the suction chamber and the saline bag. No more equipment needs to be moved, which reduces the floor space and is convenient for medical staff to operate.

[0029] The sputum suction hose and sputum bag in the utility model are both disposable items, which are discarded after one sputum suction is completed. During installation, the sputum suction hose and the sputum bag are taken out of the sterile bag, the sputum bag is installed on the bottom outlet of the sputum suction chamber, the negative pressure tube is connected to the negative pressure machine or the negative pressure outlet end, the sputum suction hose is connected to an interface of the three-way valve, the dilution tube on the sputum suction hose is connected to one saline tube of the physiological saline bag, and the other saline tube of the physiological saline bag is connected to the other interface of the three-way valve.

[0030] When suctioning the patient, adjust the three-way valve to connect the suction hose, extend the suction hose into the patient's respiratory tract or lung sputum area, adjust the negative pressure regulating valve, select the appropriate negative pressure, and the sputum is sucked out under the action of negative pressure, enters the suction cavity through the suction tube and falls into the sputum bag below. When the sputum is too thick to be sucked out, open the saline regulating valve connected to the dilution tube, inject physiological saline into the patient's body, dilute the thick sputum, and facilitate sputum suction. After suctioning, adjust the three-way valve, connect the saline tube, adjust the saline regulating valve on the saline tube, and flush the suction tube and the suction cavity with physiological saline to prevent sputum from sticking to the inner wall of the suction tube and the suction cavity, so that the next patient can use it.
