[0040] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] like Figure 1 、 Figure 2 and Figure 3 As shown, the utility model provides a negative pressure aspirator with liquid level identification, including a frame 1 and a liquid level tank 2, a negative pressure suction device 3, a camera 4 and a display 5 arranged on the frame 1. A scale is provided on the side of the liquid level tank 2, and a first interface 21 and a second interface 22 are provided thereon. The first interface 21 is connected to the negative pressure suction device 3 through a first conduit 9, and the second interface 22 is connected to a second conduit for suction (not shown in the figure), and the distal end of the second conduit is connected to the human body. A switch valve can also be provided on the second conduit for turning on or off the suction operation (not shown in the figure). The camera 4 faces the side of the liquid level tank 2, and is connected to the display 5 through a circuit board 10 (or PCB board), and is used to present the amount of blood corresponding to the blood level in the liquid level tank 2 on the display 5 in real time. The negative pressure suction device 3 includes a pump 31 and a motor 32 connected to the pump 31, as shown Figure 4 As shown, the pump 31 can be a diaphragm pump or other suitable pump. The first interface 21 is connected to the suction port of the pump 31 through the first conduit 9, and is used to suck the gas in the liquid level tank 2 so that the liquid level tank 2 always maintains a negative pressure state during operation, which is convenient for doctors to perform blood extraction operations.

[0042] The liquid level tank 2 can be a sealed tank with a scale. Blood is drawn into the tank 2 under negative pressure via a second catheter. A camera 4 automatically captures the blood level in the tank 2 and transmits this information to a display 5, displaying blood volume information. The doctor can quickly obtain information about the aspirated blood by simply looking at the display 5, rather than the scale on the tank 2. This allows for accurate liquid level identification and is widely used in thrombus aspiration procedures.

[0043] According to a specific embodiment of the present invention, as 1 and Figure 4As shown, the frame 1 includes a hollow shell 11 and a bracket 12 positioned within the interior of the shell 11. The top of the shell 11 forms a recess 13, into which the liquid level tank 2 is snapped, allowing the liquid level tank 2 to be easily removed for cleaning. According to one embodiment of the present invention, an adapter connector 8 is mounted on the top of the shell 11. The upper end of the adapter connector 8 is connected to the first interface 21 on the liquid level tank 2 via a first conduit 9, and the lower end of the adapter connector 8 is connected to the pump suction port via an air duct 20. The camera device 4 may include a mounting bracket 41 and a camera lens 42. The mounting bracket 41 is fixed to the bracket 12. The camera lens 42 is disposed on the mounting bracket 41, located on the upper side of the recess 13 and facing the side scale of the liquid level tank 2, and transmits real-time information about the liquid level on the side of the liquid level tank 2 to the display 5. The negative pressure suction device 3 may be mounted to the bottom of the bracket 12 via a fixed bracket 33. In order to reduce the vibration impact of the pump 31 and motor 32 on the entire device, a shock-absorbing column 34 is also installed at the supporting position of the fixed bracket 33 to further block the vibration conduction effect, making the entire negative pressure suction device more stable during operation and avoiding the impact on the liquid level tank 2.

[0044] According to a specific embodiment of the present invention, the display 5 can be mounted on the top of the housing 11 via a harness support riser 51. The display 5 can rotate relative to the harness support riser 51. The doctor can rotate the display 5 according to their own position to better view the screen information. The display 5 can be a flat-panel display or other suitable display. The camera device 4 records the liquid level of the liquid level tank 2 in real time, calculates the liquid level in real time through an algorithm, and displays the real-time liquid level on the display 5. According to another embodiment of the present invention, a pressure sensor (not shown) can be installed on the liquid level tank 2 so that the display 5 can display both the liquid level information of the liquid level tank 2 and the real-time negative pressure value information.

[0045] According to a specific embodiment of the present invention, Figure 5 and Figure 6 As shown, a power socket 111, a power switch 112, and a heat dissipation vent 113 are also installed on the outer side of the housing 11. The power switch 112 is connected to the display 5 and the motor 32. The heat dissipation vent 113 corresponds to the installation position of the motor 32 and the pump 31 and is used to evacuate the heat generated by the operation of the pump 31 and the motor 32. The heat dissipation vent 113 is preferably located in the lower area of ​​the outer side of the housing 11. During use, the power cord is connected to the power supply and the power socket 111, and the power switch 112 is turned on to put the display 5, the pump 31, and the motor 32 into operation.

[0046] like Figure 5As shown, in terms of the external structure of the present invention, the upper cross-section of the shell 11 is circular, and the lower cross-section is square. The shell 11 gradually transitions from the square cross-section at the lower end to the circular cross-section at the upper end, and the lower cross-section of the shell 11 is larger than the upper cross-section, making the overall appearance more coordinated.

[0047] In addition, according to a specific embodiment of the present invention, a winding module 14 for storing the power cord is further provided in the middle area of ​​the outer side of the frame 1. The winding module 14 is a T-shaped or oval structure installed on the outer side of the housing. When in use, the power cord can be simply wound around the T-shaped or oval structure. After use, the power cord is then wound around the T-shaped or oval structure for storage, making the entire negative pressure aspirator more regular.

[0048] According to a specific embodiment of the present invention, a base is further fixed to the lower end surface of the frame, and a universal wheel is installed on the base.

[0049] During operation, the power cord is removed from the winding module, one end is plugged into a power source, and the other end is plugged into a power outlet. The power switch is turned on, and the motor starts to work, creating a negative pressure environment inside the pump, sucking out the gas in the liquid level tank. The liquid level tank gradually forms a negative pressure with the outside world (the human body). The second catheter is connected to the human body, and the switch on the second catheter is turned on to start the suction operation. Blood and thrombus enter the liquid level tank through the second catheter. The camera device continuously captures images of the liquid level tank and displays the corresponding liquid level information on the flat panel display. After the suction is completed, the switch valve on the second catheter is closed, the second catheter is pulled out of the human body, and the power switch is turned off. Finally, the power cord is wrapped around the winding module and moved to a fixed position.

[0050] This utility model secures a pump, liquid level tank, and flat-panel display to a single frame. The tank, pump, motor, camera, and display form a single integrated structure with the multiple modules of the frame. Universal wheels are located at the bottom of the frame for easy mobility. The camera allows for accurate liquid level identification, making it widely applicable in thrombus aspiration procedures. Furthermore, a reserved area in the lower half of the frame houses the pump and motor, making the overall structure more compact and easier to move and transport.

[0051] Any matters not described in this utility model are applicable to the prior art.

[0052] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
