When the cannula 107 is pulled out of the patient's mouth, it will enter the isolation tube 1 03, and the outer wall of the sleeve 107 is provided with a slide groove 110, and the slide groove 110 will be engaged with the limit block 111 on the inner wall of the isolation tube 103, so the sleeve 107 will drive the isolation tube 103 to slide in the protective tube 101 during the upward sliding process, and when the protective tube 101 slides upward, the isolation cover 112 will be driven to be closed under the action of the connecting rod 113, and when the sleeve 107 completely enters the protective tube 101, the isolation cover 112 will be completely closed, so that the mucus attached to the surface of the sleeve 107 will not leak out, thereby preventing the mucus from dripping on the patient's body or bed, thereby improving the sealing of the device and preventing secondary contamination.

[0041] At the same time according to Figure 7 and Figure 8As shown, the fixing mechanism 2 includes a fixing cylinder 201, one end of the outer wall of the fixing cylinder 201 is threadedly connected to a fixing head 202, the outer wall of the fixing cylinder 201 is respectively fixedly installed with a first strap 203 and a second strap 204, one side of the outer wall of the first strap 203 and the second strap 204 is respectively fixedly installed with a furry surface 205 and a thorny surface 206, the fixing head 202 can be inserted into the patient's mouth, or connected to the air supply pipe, and the first strap 203 and the second strap 204 can be tied to the patient's head, and then the furry surface 205 and the thorny surface 206 are bonded, so that the entire fixing mechanism 2 and the sputum suction mechanism 1 can be fixed to the patient's head position to prevent the sputum suction mechanism 1 from slipping from the patient's head position, so that the subsequent sputum suction operation can be facilitated.

[0042] according to Figure 7 and Figure 8 As shown, a splash-proof cylinder 207 is fixedly installed on one side of the outer wall of the fixed cylinder 201, and a waterproof cotton 208 is arranged on the inner wall of the splash-proof cylinder 207. When suctioning sputum of a patient, the patient may feel uncomfortable and cough, and the patient may easily cough up sputum or liquid medicine from the mouth during the coughing process. At this time, the splash-proof cylinder 207 can prevent the liquid medicine or sputum from splashing out, contaminating the bed sheets or splashing onto the medical staff, causing secondary pollution, and the waterproof cotton 208 can also absorb the liquid medicine or sputum, greatly improving the splash-proof efficiency of the splash-proof cylinder 207, thereby improving the hygiene of the device.

[0043] according to Figure 7 and Figure 8 As shown, the bottom of the splash-proof cylinder 207 is fixedly connected to a conduit 209, and the output end of the conduit 209 is fixedly connected to a waste liquid bag 210. The liquid medicine or sputum sprayed from the patient's mouth will enter the waste liquid bag 210 through the conduit 209 for unified collection, thereby improving the safety and hygiene of the device.

[0044] according to Figure 1-Figure 4 As shown, the output end of the suction tube 109 is fixedly connected to a top cover 115, the bottom of the top cover 115 is threadedly connected to a fluid collection box 116, the top of the fluid collection box 116 is fixedly connected to an exhaust pipe 117, and a connecting end 118 is arranged at the input end of the exhaust pipe 117, and an air bag 119 is threadedly inserted at the top of the connecting end 118. The exhaust pipe 117 will be connected to a designated suction device, so that negative pressure can be generated in the suction tube 109, so that sputum will enter the fluid collection box 116 through the suction tube 109 for unified collection. When the hospital is out of power or it is inconvenient to use the suction device for suctioning sputum, it is only necessary to connect the air bag 119 to the input end of the exhaust pipe 117, so that when the medical staff presses the air bag 119, it can also achieve the effect of suctioning sputum, thereby improving the versatility and practicality of the device.

[0048] according to Figure 1 and Figure 2 As shown, the fixing tube 201 is fixedly sleeved on one end of the outer wall of the protection tube 101 .

[0049] The method of use and working principle of the device are as follows: when using, first take the device out of the sealed bag, then insert the fixed head 202 into the patient's mouth, or connect it to the air supply tube, and the first strap 203 and the second strap 204 can be tied to the patient's head, and then the fur surface 205 and the thorny surface 206 are bonded together, so that the entire fixing mechanism 2 and the sputum suction mechanism 1 can be fixed to the patient's head position to prevent the sputum suction mechanism 1 from slipping from the patient's head position, and then the device can be hung at a designated position through the hanging ring 124, so that it is convenient for medical staff to perform subsequent sputum suction operations, and then the medical staff can insert the sleeve 107 into the patient's body through the isolation bag 105, and there is no need to perform additional disinfection on the sleeve 107, which can improve the sputum suction efficiency. Efficiency, and when the medical staff inserts the cannula 107 into the patient's body, they can observe the scale bar 125, so that the cannula 107 can be accurately inserted into the designated position, which can reduce the probability of medical accidents, and the cannula 107 is inserted with a medicine tube 108 and a liquid suction tube 109, the medicine tube 108 can be connected to a designated infusion device, so that expectorant liquid and other liquid medicines can be introduced into the patient's body through the medicine tube 108, which is convenient for expectorant treatment, and then the suction tube 117 will be connected to the designated suction device, when the suction device is running, it can generate negative pressure in the liquid suction tube 109, so that the sputum in the patient's body can be extracted, and the extracted sputum will enter the liquid collection box 116 through the liquid suction tube 109 for unified collection, and the liquid collection box 116 is transparent , it is convenient for medical staff to observe the color of mucus and thus judge the patient's condition, and the effusion box 116 can be easily disassembled, so it is also convenient for medical staff to test sputum, thereby improving the practicability and portability of the device. When the hospital is out of power or it is inconvenient to use suction equipment to suction sputum, it is only necessary to connect the air bag 119 to the input end of the suction tube 117, so that when the medical staff presses the air bag 119, it can also achieve the effect of suctioning sputum, which can improve the versatility and practicability of the device. The sputum can be sucked out of the patient's body through the suction tube 109, so there is no need to insert and pull out the tube additionally, which can not only reduce the risk of infection of the patient, but also prevent harm to the patient during the process of inserting and pulling out the tube, which can increase the safety of the device and improve the safety of the patient. During the suction process, the medical staff can press the pressure relief valve 121. When the amount of suction needs to be controlled, the medical staff only needs to release the pressure relief valve 121. At this time, the suction pipe 117 will become positive pressure, thereby stopping suction. Therefore, by controlling the size of the opening of the pressure relief valve 121, the suction force can be controlled, thereby improving the practicality of the device. During the suction process, the patient may feel uncomfortable and cough, and it is easy for the patient to cough up sputum or liquid medicine from the mouth during coughing. At this time, the splash guard 207 can prevent the liquid medicine or sputum from splashing out, contaminating the bed sheets or splashing onto the medical staff, causing secondary pollution, and the waterproof cotton 208 can also absorb the liquid medicine or sputum, greatly improving the splash-proof efficiency of the splash guard 207.The liquid medicine or sputum sprayed from the patient's mouth will enter the waste liquid bag 210 through the catheter 209 for unified collection, thereby improving the safety and hygiene of the device. After the suction is completed, the sleeve 107 needs to be taken out of the patient's mouth. When the sleeve 107 is pulled out of the patient's mouth, it will enter the isolation tube 103, and the outer wall of the sleeve 107 is provided with a slide groove 110, and the slide groove 110 will be engaged with the limit block 111 on the inner wall of the isolation tube 103, so the sleeve 107 will drive the isolation tube 103 to slide in the protective tube 101 during the upward sliding process. When the cylinder 103 slides upward, the connecting rod 113 drives the isolation cover 112 to close. When the sleeve 107 completely enters the protective cylinder 101, the isolation cover 112 will be completely closed, so that the mucus attached to the surface of the sleeve 107 will not leak out, and the sponge 126 can absorb the sputum on the surface of the sleeve 107 to prevent the sputum from dripping, thereby greatly improving the sealing of the device, thereby preventing mucus from dripping on the patient's body or bed, thereby improving the sealing of the device and preventing secondary contamination. In summary, the problems raised in the above background are solved.
