[0029] Example:

[0030] Reference Figures 1-5 This utility model embodiment provides a drainage device to avoid blockage of the drainage tube, including a drainage shell 1 for connecting the drainage tube, and further including: a piston 3 installed inside the drainage shell 1, wherein the drainage shell 1 is provided with a drainage part, which is used to drive the piston 3 to reciprocate along the inner wall of the drainage shell 1, so as to generate negative pressure inside the drainage shell 1, and an air hole is opened through one end of the drainage shell 1 for venting when the piston 3 moves; an elastic ball 5 installed on the drainage shell 1, the elastic ball 5 being made of silicone, wherein the drainage shell 1 is provided with a linkage part, which is used to drive the elastic ball 5 to continuously strike the drainage tube, and a handle 10 is fixedly connected to one end of the drainage shell 1, the handle 10 being provided with anti-slip texture 11, which facilitates medical personnel to apply force to pick up the device.

[0031] Specifically, during use, the drainage unit automatically draws out tissue fluid from the patient's body through the drainage tube and stores it in the collection cup 42. The continuous negative pressure generated by the mechanical output reduces the possibility of tissue fragments and other substances accumulating in the drainage tube, thereby reducing the probability of blockage. The linkage unit can also drive the elastic ball 5 to continuously tap the drainage tube, causing it to vibrate. Under the combined effect of negative pressure and vibration, the tissue material that has accumulated in the drainage tube along with the fluid can be loosened, allowing the tissue fluid to be more smoothly drawn into the drainage shell 1 by the negative pressure, further reducing the probability of drainage tube blockage and ensuring the reliability of the patient's treatment.

[0032] The drainage device for preventing drainage tube blockage includes a motor 31 fixedly mounted on a drainage shell 1. A reciprocating screw 32 is rotatably connected inside the drainage shell 1. One end of the reciprocating screw 32 is fixedly connected to the output end of the motor 31. A reciprocating slider 33 is mounted on the reciprocating screw 32 for use therewith. The reciprocating slider 33 is slidably mounted inside the drainage shell 1. A piston 3 is fixedly connected to the reciprocating slider 33. A liquid suction element is provided on the drainage shell 1.

[0033] Specifically, during use, by starting the motor 31, the output end of the motor 31 drives the reciprocating screw 32 to rotate, causing the reciprocating slider 33 to drive the piston 3 to slide back and forth in the drainage shell 1, thereby generating negative pressure in the drainage shell 1, which can draw the tissue fluid in the patient's body into the drainage shell 1 through the drainage tube and collect it.

[0034] The above-mentioned liquid suction device includes a liquid suction tube 2 and a liquid discharge tube 4 connected to the drainage shell 1. The liquid suction tube 2, the liquid discharge tube 4 and the cup cover 41 are all equipped with one-way valves. The cup cover 41 is installed on the liquid discharge tube 4 and a collection cup 42 is threadedly connected to the cup cover 41.

[0035] Specifically, when the piston 3 reciprocates, the tissue fluid in the drainage tube is drawn into the drainage shell 1 through the drain pipe 4, and then discharged into the collection cup 42 for centralized storage. The backflow of tissue fluid can be prevented by the one-way valves on the suction pipe 2 and the drain pipe 4, and the gas can be discharged by the one-way valve on the cup lid 41.

[0036] A guide rod 34 is fixedly connected inside the aforementioned drainage shell 1, and a guide block 35 is fixedly connected to the reciprocating slider 33. The guide block 35 is slidably connected to the guide rod 34.

[0037] Specifically, by setting up the guide rod 34 and the guide block 35, the reciprocating slider 33 can be guided, thereby improving the stability of the lateral movement of the reciprocating slider 33.

[0038] The surface of the collection cup 42 is provided with scale lines 13, and the material of the collection cup 42 is transparent plastic.

[0039] Specifically, the scale line 13 allows medical staff to easily check the storage status of tissue fluid in the collection cup 42.

[0040] The aforementioned linkage includes a vertical plate 71 fixedly connected to the drainage shell 1, a rotating rod 72 rotatably connected to the vertical plate 71, a cam 7 fixedly connected to one end of the rotating rod 72, and pulleys 73 fixedly connected to the other end of the rotating rod 72 and the surface of the reciprocating lead screw 32. The two pulleys 73 are connected by a belt. A support plate 6 is fixedly connected to the drainage shell 1, and an elastic ball 5 is connected to the support plate 6 by an elastic element. A protective shell 12 is detachably installed on the drainage shell 1, and the rotating rod 72 and the pulleys 73 are both located inside the protective shell 12.

[0041] Specifically, when the reciprocating screw 32 rotates, it also drives the pulley 73 and the rotating rod 72 to rotate, and drives the cam 7 to rotate together. Through the cooperation of the rotating cam 7 and the elastic element, the elastic ball 5 can be driven to continuously tap the drainage tube, causing the drainage tube to vibrate. Under the combined support of negative pressure and vibration, the tissue material that has accumulated in the drainage tube with the fluid can be loosened, and the tissue fluid can be more smoothly sucked into the drainage shell 1 by the negative pressure, thereby reducing the probability of drainage tube blockage and ensuring the reliability of treatment for patients. In addition, the protective shell 12 can shield and protect the rotating rod 72 and the pulley 73, and improve the appearance of impurities.

[0042] The aforementioned elastic element includes a slide rod 61 slidably mounted on the drainage shell 1, a vertical rod 62 slidably connected to the support plate 6, the slide rod 61 being fixedly connected to the top of the vertical rod 62, an elastic ball 5 being fixedly connected to the bottom of the vertical rod 62, a spring 63 being sleeved on the vertical rod 62, the two ends of the spring 63 being fixedly connected to the surfaces of the slide rod 61 and the support plate 6 respectively, a cam 7 being located above the slide rod 61, a groove 8 being provided on the drainage shell 1, a moving block 9 being fixedly connected to one end of the slide rod 61, and the moving block 9 being slidably connected longitudinally within the groove 8.

[0043] Specifically, when the rotating rod 72 rotates, it drives the cam 7 to intermittently slide over the surface of the slide rod 61. With the cooperation of the cam 7, the slide rod 61, the vertical rod 62 and the spring 63, the elastic ball 5 can be driven to perform reciprocating up and down motion, thereby continuously striking the drainage tube. Furthermore, through the setting of the slide groove 8 and the moving block 9, the slide rod 61 can be guided to prevent it from deflecting under the squeezing force of the cam 7.

[0044] Working principle: In the process of using this drainage device that avoids drainage tube blockage, first connect the drainage tube's drain end to the suction tube 2, then start the motor 31. The output end of the motor 31 drives the reciprocating screw 32 to rotate, causing the reciprocating slider 33 to drive the piston 3 to slide back and forth in the drainage shell 1. This generates negative pressure in the drainage shell 1, allowing the tissue fluid in the patient's body to be drawn into the drainage shell 1 through the drainage tube and the drain tube 4, and then discharged into the collection cup 42 through the drain tube 4. Through the cooperation of the motor 31, piston 3, and collection cup 42, the device can automatically draw out the tissue fluid in the patient's body through the drainage tube and store it in a concentrated manner. The continuous negative pressure generated by the mechanical output can reduce the possibility of tissue fragments and other substances depositing in the drainage tube, thereby reducing the probability of blockage.

[0045] Furthermore, during the drainage process, when the reciprocating screw 32 rotates, it also drives the pulley 73 and the rotating rod 72 to rotate, and drives the cam 7 to intermittently slide over the surface of the slide rod 61. With the cooperation of the cam 7, the slide rod 61, the vertical rod 62 and the spring 63, the elastic ball 5 can be driven to continuously tap the drainage tube, causing the drainage tube to vibrate. Under the combined support of negative pressure and vibration, the tissue material that has accumulated in the drainage tube with the fluid can be loosened, thereby allowing the tissue fluid to be more smoothly drawn into the drainage shell 1 by negative pressure, further reducing the probability of drainage tube blockage, thus ensuring the reliability of the patient's treatment.
