[0035] The support assembly 1 includes a lower slide 101, an extrusion frame 102, an upper slide 103, a support shell 104, a connecting seat 105, an adjustment seat 106, and a telescopic slide 107; the interior of the support shell 104 is set to be hollow, and the lower slide 101 is symmetrically arranged at the front end to slide and connect the limit slider 202, and the extrusion frame 102 is symmetrically arranged at the outer end, and the two sides are symmetrically provided with threaded holes to thread the adjustment screw 204, and the adjustment seat 106 is arranged on the left side, and the connecting seats 105 are arranged on both sides of the front end to rotatably connect the flip assembly 3; the extrusion frame 102 is provided with an upper slide 103 to slide and connect the limit slider 202, and the front end is slidably connected to the telescopic slide 107; the driving mechanism 201 is arranged inside the support shell 104;

[0036] The flip assembly 3 includes a worm gear 301, a flip motor 302, a flip plate 303, and a worm 304; the flip motor 302 is fixedly connected to the adjustment seat 106, and the output shaft 2012 is provided with a worm 304; the flip plate 303 is rotatably connected to the connection seat 105, and a worm gear 301 is provided on one side to mesh with the worm 304

[0037] In this embodiment, when the device is in use, the patient's legs are placed between the two extrusion cylinders 205 on the support shell 104, and the adjustment buttons on both sides are rotated according to the thickness of the patient's legs, driving the adjustment screw 204 to rotate, so that the adjustment screw 204 drives the limit slider 202 to slide along the upper slide groove 103 and the lower slide groove 101 through the threaded connection between the adjustment screw 204 and the support shell 104; thereby adjusting the distance between the extrusion cylinders 205 on both sides to a suitable position;

[0038] After the spacing adjustment is completed, the extrusion motor 2011 is started, so that the output shaft 2012 of the extrusion motor 2011 drives the driving gear 2013 to rotate, thereby driving the transmission gears 2014 on both sides to rotate, so that the transmission gear 2014 drives the extrusion gear 2015 to rotate, and through the fixed connection between the extrusion gear 2015 and the bottom of the extrusion cylinder 205, the extrusion gear 2015 is driven to rotate in the limit slider 202; at the same time, the transmission gear 2014 is articulated by the connecting rod to keep the rotation with the driving gear 2013 and the extrusion gear 2015;

[0041] In this embodiment, the squeezing assembly 2 is driven by a motor to realize automatic squeezing of the effusion extraction site, without the need for manual operation by the nurse, which greatly reduces the physical exertion of the nurse and improves the work efficiency. The squeezing gear 2015 drives the squeezing cylinder 205 to rotate through gear transmission, thereby achieving a uniform squeezing effect and avoiding the uneven force that may occur during manual squeezing, thereby improving the thoroughness and treatment effect of the effusion extraction, and allowing the force to be adjusted according to the patient's leg condition and squeezing needs. By adjusting the threaded connection of the screw 204, the squeezing force can be flexibly adjusted to meet the treatment needs of different patients, reducing the time for effusion extraction, improving the overall treatment efficiency, and at the same time reducing the risk caused by improper operation or contact infection to a certain extent.

[0042] In this embodiment, the flip assembly 3 drives the worm 304 to rotate by rotating the flip motor 302, thereby driving the worm wheel 301 to rotate, so that the bending angle of the patient's knee can be adjusted according to the need of extracting the effusion and the patient's comfort; the device can adapt to the individual differences of different patients, improve the flexibility and comfort of treatment, and at the same time utilize the self-locking property of the worm wheel 301 and the worm 304 to stably maintain the current angle after the adjustment is completed, avoiding the discomfort caused by fixed posture in traditional methods or angle changes during treatment; it helps to ensure the accuracy of effusion extraction while reducing the patient's pain and discomfort.

[0043] Example 2

[0044] like Figure 1-3 As shown in FIG. 6 , the extraction component 4 includes an extraction box 401, a negative pressure device 402, a filter 403, a discharge port 404, a pressure control component 405, and an extraction pipe 406; the negative pressure device 402 is arranged on the top of the extraction box 401, a hole is provided in the middle to arrange the extraction pipe 406, a filter 403 is arranged inside, and a discharge port 404 is arranged at the rear end; the pressure control component 405 is arranged at the front end of the extraction pipe 406; the front end of the extraction pipe 406 is L-shaped;

[0045] The pressure control assembly 405 includes a pressure regulating ball 4051, a pressure regulating spring 4052, a pressure regulating plate, an adjusting screw 4054, an adjusting knob 4055, and a pressure regulating tube 4056; a pressure regulating tube 4056 is arranged at the bending position of the front end of the extraction tube 406, and a hole is provided at the rear end of the pressure regulating tube 4056 to be threadedly connected with the adjusting screw 4054; a pressure regulating plate is arranged at the front end of the adjusting screw 4054, and an adjusting knob 4055 is arranged at the rear end; a pressure regulating spring 4052 is arranged at the front end of the pressure regulating plate; a pressure regulating ball 4051 is arranged at the front end of the pressure regulating spring 4052; a plurality of micro holes are arranged at the rear ends of the pressure regulating plate and the pressure regulating tube 4056;

[0046] In this embodiment, when the device is in use, the front end of the extraction tube 406 is connected to the puncture needle, and a negative pressure is formed in the extraction box 401 through the negative pressure device 402, so that the accumulated fluid in the patient's body can be extracted, and the accumulated fluid is filtered through the filter 403 set in the extraction box 401. After the extraction is completed, the accumulated fluid can be discharged through the discharge port 404;

When the negative pressure in the extraction box 401 is less than the set negative pressure value, the negative pressure in the extraction box 401 absorbs the pressure regulating ball 4051 and separates it from the pressure regulating tube 4056, so that the external air is discharged through the micropores on the pressure regulating plate and the pressure regulating tube 4056, and the internal air pressure of the extraction box 401 is adjusted;

[0048] In this embodiment, the extraction component 4 automatically generates negative pressure through the negative pressure device 402 without manual operation, which greatly reduces the physical exertion of medical staff, improves the extraction efficiency, and makes the treatment of effusion faster. A filter 403 is arranged inside the extraction component 4, which can filter the extracted effusion, remove impurities, improve the quality of the effusion, and facilitate subsequent analysis and treatment. A pressure control component 405 is arranged at the front end of the extraction tube 406, which can adjust the negative pressure inside the extraction box 401 as needed, so as to control the extraction pressure, making the extraction process more flexible and able to be adjusted according to the specific situation of the patient, thereby improving the safety and comfort of the extraction.

[0049] In summary, the present invention realizes automatic squeezing of the effusion extraction site by setting a built-in squeezing assembly 2, which is driven by a motor and driven by a gear transmission, so that the squeezing gear 2015 drives the squeezing cylinder 205 to rotate, without the need for manual operation by nurses, which greatly reduces physical exertion and improves the uniformity and efficiency of squeezing. In addition, by adjusting the threaded connection of the screw 204, the device allows the strength to be adjusted according to the patient's leg condition and squeezing needs, thereby ensuring the thoroughness of the effusion extraction and the therapeutic effect.

[0050] At the same time, a flip component 3 is provided, and the worm 304 is driven to rotate by rotating the flip motor 302, thereby driving the worm wheel 301 to rotate, so that the bending angle of the patient's knee can be adjusted according to the need of extracting the effusion and the patient's comfort. At the same time, the self-locking property of the worm wheel 301 and the worm 304 can stably maintain the current angle after the adjustment is completed, avoiding the discomfort caused by the fixed posture in the traditional method.
