[0002] A negative pressure aspirator is a tool that creates a negative pressure state at its suction head through a certain method, and the substances outside the suction head are squeezed towards the suction head, thereby completing the "suction" effect.

[0003] However, in the actual use process of the current negative pressure aspirator, the feed pipeline above the aspirator body is easily blocked by relatively viscous substances such as blood and sputum, thus affecting the use of the negative pressure aspirator and delaying the rescue time of patients. Therefore, the staff in this field have proposed an anti-blocking negative pressure aspirator. Summary of the Utility Model

By inserting the second suction pipe into the human body, during use, under the negative pressure of the aspirator body, the viscous substances to be sucked can be sucked out from the human body through the second suction pipe. When the viscous substances enter above the aspirator body, its anti-blocking component stirs the viscous substances during continuous rotation to prevent the substances from solidifying, and at the same time, the anti-blocking component moves up and down during continuous rotation, thereby further avoiding the phenomenon that the viscous substances accumulate too much and congest the pipeline above the aspirator body.

[0031] Please refer to Figures 1-3 , an anti-blocking negative pressure aspirator, comprising an aspirator body 1. An inlet 2 is provided at the upper end of the aspirator body 1. A sealing door panel 3 is movably connected to the side end of the aspirator body 1. An adapter platform 4 is fixedly connected to the upper end of the aspirator body 1. Two anti-blocking through holes 5 which are axially symmetrically arranged and are frustum-shaped are provided at the inner bottom end of the adapter platform 4. A conical groove 6 is provided at the upper end of the adapter platform 4. The inlet 2, the anti-blocking through holes 5, and the conical groove 6 are in communication with each other. A sealing plate is fixedly connected to the upper end of the adapter platform 4. An anti-blocking assembly 7 is installed at the central end of the bottom side of the sealing plate. A first straw 8 is embedded and installed at the upper end of the sealing plate. A pressure control valve 9 is installed at the upper end of the first straw 8. A pressure gauge 10 is installed at the upper end of the pressure control valve 9. A second straw 11 is installed at the side end of the pressure control valve 9.

[0032] During the use of this solution, in order to avoid the phenomenon that the existing negative pressure aspirator is blocked by relatively viscous substances such as blood and sputum, in this embodiment, first, the second straw 11 is inserted into the human body. When in use, under the negative pressure of the aspirator body 1, the viscous substances to be aspirated can be sucked out from the human body through the second straw 11. When the viscous substances enter above the aspirator body 1, the anti-blocking assembly 7 stirs the viscous substances during continuous rotation to prevent the substances from solidifying. And while the anti-blocking assembly 7 rotates continuously, it moves up and down, thereby further avoiding the phenomenon that the viscous substances accumulate too much and congest the pipeline above the aspirator body 1.

[0033] Please refer to Figures 2-3 , a plurality of connecting plates 21 are fixedly connected between the inner walls of the inlet 2. A first disc 22 is fixedly connected to the central connecting end of the plurality of connecting plates 21. A second disc 23 is rotatably connected to the upper end of one side of the first disc 22. A positioning rod 24 is installed at the upper end of the other side of the first disc 22, and the top of the positioning rod 24 is in contact with the bottom end of the second disc 23.

[0034] More specifically: the positioning rod 24 is arranged as a threaded rod and is threadedly connected to the first disc 22.

[0035] During the use of this solution, the operator installs a connecting plate 21 and a first disc 22 between the inner walls of the feeding port 2, and rotatably connects an inclined second disc 23 to the upper end of the first disc 22. A positioning rod 24 is arranged at the inclined bottom on one side of the second disc 23. At the same time, the positioning rod 24 is a threaded rod so that the inclined height on one side of the second disc 23 can be adjusted, thereby adjusting the up-and-down movement height of the upper anti-blocking component 7.

[0036] Please refer to Figures 2-3 , the anti-blocking component 7 includes a motor 71 installed at the central end of the bottom side of the sealing plate. The lower end of the motor 71 is fixedly connected to a first connecting rod 72. The lower end of the first connecting rod 72 is fixedly connected to two symmetrically distributed limiting rods 73. The central end of the bottom side of the first connecting rod 72 is fixedly connected to a limiting column 75. A conical pedestal 74 is arranged between the inner walls of the anti-blocking through hole 5. The limiting rods 73 and the limiting column 75 both penetrate between the inner walls of the conical pedestal 74 and are movably connected thereto. A spring 76 is fixedly connected between the first connecting rod 72 and the top end of the conical pedestal 74. The lower end of the conical pedestal 74 is fixedly connected to a second connecting rod 77.

[0037] More specifically, a spherical groove is formed in the side end of the conical pedestal 74, and a first ball 78 is movably connected between the inner walls of the spherical groove.

[0038] During the use of this solution, during the operation of the suction device body 1, the operator synchronously starts the motor 71, causing the first connecting rod 72 connected to the output end to drive the conical pedestal 74 to rotate because the limiting rod 73 penetrates into the conical pedestal 74. At the same time, due to the movable connection between the conical pedestal 74 and the limiting rod 73 and the support of the second connecting rod 77 at the bottom of the conical pedestal 74 above the second disc 23, since the second disc 23 is inclined, when the second connecting rod 77 at one side of the bottom of the conical pedestal 74 rotates to the lowest end of the second disc 23, the conical pedestal 74 moves downward, thereby increasing the feeding diameter of the anti-blocking through hole 5. As it continues to rotate and is at the same height again, it dredges the viscous substance inside the anti-blocking through hole 5 to avoid blockage.

[0039] Please refer to Figure 3 , the lower end of the second connecting rod 77 is movably connected to a second ball.

[0040] During the use of this solution, by arranging a second ball at the bottom of the second connecting rod 77, the second connecting rod 77 can rotate more smoothly above the second disc 23, reducing the friction between the two.

[0041] The above-described embodiments merely represent certain implementation manners of the present utility model. Their descriptions are relatively specific and detailed, but should not be construed as limitations on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
