DETAILED DESCRIPTION

[0032] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0033] Example: Figure 1 and Figure 2 As shown, a convenient sputum suction device is provided. When the sputum suction device is needed, the sputum suction tube 8 is inserted into the patient's oral cavity, usually inserted into the throat through the sublingual part, and the sputum suction tube 8 is made of silicone material, which is softer and makes the patient more comfortable when using it; then the person places the palm of his hand against the annular handle 5, and holds the pull rod 4 with the index finger, middle finger and thumb to push the piston rod 3 connected to the pull rod 4 forward, so that the piston 2 installed at the bottom of the piston rod 3 moves forward from the top plate 6 inside the pull rod tube 1, wherein the piston 2 is tightly fitted to the inner wall of the pull rod tube 1, so that the piston 2 continuously forms a negative environment inside the pull rod tube 1 during the forward movement of the piston 2, and the sputum will be sucked into the sputum suction tube 8 through the negative pressure effect, and with the push of the piston 2, the sputum gradually moves in the sputum suction tube 8 to the palm position; since the starting end of the sputum suction tube 8 is sleeved on the connecting column 7, On the pipeline extending sideways, therefore, sputum will enter the connecting column 7. Since the connecting column 7 is a rubber tube made of rubber, the lower end of the connecting column 7 is inserted into the hole correspondingly opened above the sealed cover 13. By utilizing the large frictional force of rubber itself, the connecting column 7 can be connected to the center above the sealed cover 13, so the sputum flows into the sputum collecting bottle 9 through the sealed cover 13. When the sputum is collected once, in order to prevent the sputum from being exposed to the air and spreading bacteria and viruses, the personnel grabs the push rod 10 extending from the groove on the surface of the sealed cover 13. Since the push rod 10 is connected to the baffle 11 through a connecting strip, wherein the connecting strip and the baffle 11 are both located at the hollow groove inside the sealed cover 13, the push rod 10 is pushed forward so that the baffle 11 closes the central through hole of the sealed cover 13, thereby reducing the direct contact between the sputum inside the sputum collecting bottle 9 and the air.

[0034] like Figure 3 and Figure 4As shown, a reinforcing net 15 is wrapped within a certain distance from the beginning of the sputum suction tube 8, and the fixing column 16 installed on the top of the reinforcing net 15 through the connecting plate is inserted into the fixing holes 17 equidistantly opened in the connecting ring 14, and then the soft patches 18 at both ends of the fixing column 16 rebound and clamp the connecting ring 14, so that the reinforcing net 15 can be kept fixedly wrapped on the surface of the sputum suction tube 8; wherein the reinforcing net 15 is made of nickel-titanium alloy, which has a special shape memory effect and superelastic characteristics. When subjected to a large deformation pressure, it can recover to its original shape at a faster speed. The original shape is a diamond mesh structure made of nickel-titanium alloy material. When the suction tube 8 is squeezed by external force, the diamond mesh begins to shrink. If the pressure is increased until the diamond mesh is completely shrunk until each nickel-titanium alloy wire is arranged in a straight line, the reinforcing mesh 15 will no longer shrink, thereby forming a stable structure, so that the internal suction tube 8 is almost unaffected; when the external force no longer applies pressure, the nickel-titanium alloy wires begin to gradually recover from being arranged in a straight line to a diamond shape, thereby driving the suction tube 8 to return to its original state, so that the possibility of the suction tube 8 being bent is significantly reduced.

[0035] like Figure 1 , Figure 5 As shown, when the user is not using the suction device, for the convenience of carrying, the pipeline on one side of the connecting column 7 is pulled out from the extension pipeline of the pull rod tube 1, that is, the pull rod tube 1 and other structures and the sputum collecting bottle 9 and other structures are separated. Therefore, the sputum collecting bottle 9 is placed on the backing plate 19 connected to the fastening ring on the surface of the pull rod tube 1, and the ring 20 connected to the fastening ring above limits the sputum collecting bottle 9. The fastening ring is also made of rubber material and can be tightly fitted on the surface of the pull rod tube 1 due to its own rubber properties. At the same time, the sputum suction tube 8 connected to the other side of the connecting column 7 will be wrapped around and inserted into the sleeve fixed on the surface of the fastening ring to achieve the effect of shrinking the device.

[0036] Working principle: First, when the sputum suction device is needed, the sputum suction tube 8 is inserted into the patient's oral cavity, usually inserted into the throat through the sublingual part, and the sputum suction tube 8 is made of silicone, which is softer and more comfortable for the patient to use; then the person places the palm of his hand against the annular handle 5, and holds the pull rod 4 with the index finger, middle finger and thumb to push the piston rod 3 connected to the pull rod 4 forward, so that the piston 2 installed at the bottom of the piston rod 3 moves forward from the top plate 6 inside the pull rod tube 1, wherein the piston 2 is tightly fitted to the inner wall of the pull rod tube 1, so that the piston 2 continuously forms a negative environment inside the pull rod tube 1 during the forward movement of the piston 2, and the sputum will be sucked into the sputum suction tube 8 through the negative pressure, and as the piston 2 is pushed, the sputum gradually moves in the sputum suction tube 8 toward the palm position; since the starting end of the sputum suction tube 8 is sleeved on one side of the connecting column 7 and extends On the pipeline, therefore, the sputum will enter the connecting column 7. Since the connecting column 7 is a rubber tube made of rubber, the lower end of the connecting column 7 is inserted into the hole corresponding to the top of the sealed cover 13. By utilizing the large friction of the rubber itself, the connecting column 7 can be connected to the center above the sealed cover 13, so the sputum flows into the sputum collecting bottle 9 through the sealed cover 13. When the sputum is collected once, in order to prevent the sputum from being exposed to the air and spreading bacteria and viruses, the personnel grabs the push rod 10 extending from the groove on the surface of the sealed cover 13. Since the push rod 10 is connected to the baffle 11 through a connecting strip, and the connecting strip and the baffle 11 are both located at the hollow groove inside the sealed cover 13, the push rod 10 is pushed forward so that the baffle 11 closes the central through hole of the sealed cover 13, thereby reducing the direct contact between the sputum inside the sputum collecting bottle 9 and the air.

[0037] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
