Abstract
Description
Technical Field
[0001] This invention relates to the field of medical device technology, and in particular to a drainage device for tumor care. Background Technology
[0002] Effusion refers to the presence of liquid substances within body cavities. This fluid may appear in hollow organs such as joint cavities, abdominal cavities, thoracic cavities, and pelvic cavities. Tumor effusion refers to the abnormal accumulation of fluid in a part of the body due to the presence or influence of a tumor. Effusion drainage is a treatment method used when there is excessive or abnormal accumulation of fluid in the body. Its purpose is to drain the fluid from the body, relieve the patient's symptoms, and promote recovery. Catheter drainage: For effusion in body cavities, doctors may insert a catheter into the patient's body to drain the fluid out of the body.
[0003] Existing fluid drainage devices all use negative pressure for drainage. However, the fluid in the drainage tube cannot be disturbed during drainage, which can easily cause the fluid to clog the drainage tube, resulting in insufficient drainage and affecting the normal operation of the drainage work. Summary of the Invention
[0004] The purpose of this invention is to provide a drainage device for tumor care, which can maintain a constant drainage pressure when draining tumor fluid, and at the same time, can disturb the fluid in the drainage tube during the drainage process to prevent the fluid from blocking the drainage tube and affecting its normal operation.
[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: A fluid drainage device for tumor care includes a support base and a negative pressure pump installed in the support base. The upper end of the support base is provided with a connecting plate, and the upper end of the connecting plate is provided with a fixing ring with an upper opening. A drainage bottle is detachably connected to the fixing ring. The opening end of the drainage bottle is detachably connected to a bottle cap that is sealed to it. The left and right sides of the upper end of the bottle cap are respectively provided with a solenoid valve and a connecting pipe communicating with it. The upper ends of the solenoid valve and the connecting pipe are each equipped with a quick connector communicating with them. A barometer is installed on one side of the upper end of the bottle cap communicating with it. The air intake of the negative pressure pump is connected to the corresponding quick connector on the connecting pipe via an air extraction pipe. The air extraction pipe and the corresponding quick connector are detachably connected. A disturbance component is detachably connected to the quick connector at the upper end of the solenoid valve. A liquid guide pipe is detachably connected to the upper end of the disturbance component. Two disturbance components are provided and are respectively located at both ends of the liquid guide pipe. A drainage pipe is detachably connected to the disturbance component at the distal end of the liquid guide pipe. A control panel is provided on one side of the outer wall of the connecting plate.
[0006] By adopting the above technical solution, when using the device, first move it to the patient's bedside where drainage is needed, then power on the device, operate the control panel to close the solenoid valve, and start the negative pressure pump to evacuate air from the drainage bottle. The barometer can detect the changes in air pressure inside the drainage bottle in real time. Then, place the drainage tube at the location of the tumor that needs drainage and fix it. Then open the solenoid valve to allow the drainage tube and the guide tube to drain the effusion. During drainage, the negative pressure pump also works to evacuate air from the drainage bottle. The power of the pump is flexibly adjusted by the air pressure changes detected by the barometer, thereby maintaining a constant negative pressure state during drainage. The drained effusion will enter the drainage bottle. At the same time, during drainage, the agitation component not only allows the effusion to flow smoothly along the guide tube, but also prevents pus and blood in the effusion from clogging the guide tube.
[0007] A further embodiment of the present invention is that the support base includes a base plate, a plurality of rollers installed on the bottom of the base plate and distributed at equal intervals, a support frame disposed on the upper part of the base plate, and a support rod disposed at the middle position of the upper end of the support frame.
[0008] By adopting the above technical solution, medical staff can easily move this device. At the same time, the negative pressure pump can also lower the center of gravity of the support base, thereby ensuring its stability.
[0009] A further configuration of the present invention is as follows: the disturbance component includes a fixed tube, connecting rods respectively disposed at the upper and lower ends on the left and right sides of the inner wall of the fixed tube, rotating holes respectively passing through the middle position of the upper end of the connecting rods, rotating rods rotatably connected between the two rotating holes and extending out of their opening ends, limiting rings respectively disposed on the outer wall of the rotating rods and in contact with the corresponding connecting rods, and an impeller installed at one end of the rotating rods.
[0010] By adopting the above technical solution, the impeller is driven to rotate by the gas and liquid flow generated during negative pressure drainage. The impeller's agitation not only accelerates the flow of liquid but also prevents the liquid from clogging the drainage pipe, thus ensuring smooth drainage.
[0011] A further feature of the present invention is that: a connecting ring is provided at the other end of the rotating rod, the connecting rings of the two disturbance components are arranged correspondingly, and an elastic and spirally arranged disturbance rope is detachably connected between the two connecting rings in the liquid guide tube.
[0012] By adopting the above technical solution, the entire space inside the liquid guide tube can be disturbed through the cooperation of the two disturbance components, further preventing the blockage of liquid accumulation during drainage.
[0013] A further feature of the present invention is that a fixing bolt extending into the outer wall of the fixing ring and used to fix the drainage bottle is threadedly connected to one side of the fixing ring.
[0014] A further feature of the present invention is that the bottom of the inner wall of the drainage bottle is wedge-shaped, and a drain valve is connected to the outer wall of the drainage bottle at its lowest position. A groove for placing the drain valve is opened downward on one side of the upper end of the fixing ring.
[0015] In summary, the present invention has the following beneficial effects: Firstly, this invention can maintain a constant drainage pressure when draining tumor fluid, and at the same time, it can disturb the fluid in the drainage tube during the drainage process to prevent the fluid from blocking the drainage tube and affecting its normal operation. Secondly, the disturbance component of the present invention utilizes the flow of gas and liquid generated during negative pressure drainage to drive the impeller to rotate. The disturbance of the impeller can not only accelerate the flow of liquid but also prevent the liquid from clogging the drainage pipe, thereby ensuring the smoothness of drainage.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; or they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
[0022] Example, refer to Figure 1-4 A drainage device for tumor care includes a support base 1 and a negative pressure pump 15 installed in the support base 1. The support base 1 includes a base plate 11, a plurality of rollers 12 installed at equal intervals on the bottom of the base plate 11, a support frame 13 mounted on the upper end of the base plate 11, and a support rod 14 mounted at the middle position of the upper end of the support frame 13. The negative pressure pump 15 is mounted in the support frame 13. A connecting plate 2 is horizontally mounted on the upper end of the support base 1. A fixing ring 21 with an open upper end is mounted on the upper end of the connecting plate 2. A drainage bottle 3 is detachably connected to the fixing ring 21. The bottom of the inner wall of the drainage bottle 3 is wedge-shaped. A drain valve 31 is connected to the lowest position of the bottom of the inner wall of the drainage bottle 3. A slot 23 for placing the drain valve 31 is opened downward on one side of the upper end of the fixing ring 21. A fixing bolt 22 extending into the inner wall of the fixing ring 21 and used to fix the drainage bottle 3 is threadedly connected to one side of the outer wall of the fixing ring 21.
[0023] The opening of the drainage bottle 3 is detachably connected to a bottle cap 32 that provides a sealing connection. The bottle cap 32 and the drainage bottle 3 are fixed together by internal and external threads. A solenoid valve 33 and a connecting pipe 34 are respectively installed on the left and right sides of the upper end of the bottle cap 32. A quick connector 35 is installed at the upper end of both the solenoid valve 33 and the connecting pipe 34. A barometer 54 is installed on one side of the upper end of the bottle cap 32 and is connected thereto. The suction port of the negative pressure pump 15 is connected to the corresponding quick connector 35 on the connecting pipe 34 via a suction pipe 36. The air tube 36 is detachably connected to the corresponding quick connector 35. The quick connector 35 at the upper end of the solenoid valve 33 is detachably connected to a disturbance component 4. The disturbance component 4 includes a fixed tube 41, connecting rods 42 respectively set at the upper and lower ends of the inner wall of the fixed tube 41, rotating holes 43 respectively opened through the middle position of the upper end of the connecting rods 42, rotating rods 44 rotatably connected between the two rotating holes 43 and extending out of their opening ends, limiting rings 45 respectively set on the outer wall of the rotating rods 44 and in contact with the corresponding connecting rods 42, and an impeller 46 installed at one end of the rotating rods 44.
[0024] The upper end of the disturbance component 4 is detachably connected to a liquid guide tube 52. There are two disturbance components 4, which are respectively set at both ends of the liquid guide tube 52. The other end of each rotating rod 44 is provided with a connecting ring 5. The connecting rings 5 of the two disturbance components 4 are arranged correspondingly. A flexible and spirally arranged disturbance rope 51 is detachably connected between the two connecting rings 5 inside the liquid guide tube 52. The disturbance rope 51 can drive the two disturbance components 4 to rotate synchronously. The disturbance component 4 at the far end of the liquid guide tube 52 is detachably connected to a drainage tube 53. A control panel 55 is set on one side of the outer wall of the connecting plate 2. The negative pressure pump 15, the solenoid valve 33 and the barometer 54 are all electrically connected to the control panel 55.
[0025] Instructions for use: First, move the device to the bedside of the patient who needs drainage. Then, power on the device and operate the control panel 55 to close the solenoid valve 33 and activate the negative pressure pump 15 to evacuate air from the drainage bottle 3. The barometer 54 can detect the changes in air pressure inside the drainage bottle 3 in real time. Then, place the drainage tube 53 at the location of the tumor that needs drainage and fix it in place. Then, open the solenoid valve 33 to allow the drainage tube 53 and the fluid guide tube 52 to drain the accumulated fluid. During drainage, the negative pressure pump 15 also works to evacuate air from the drainage bottle 3. The power of the pump during evacuation is flexibly adjusted by the changes in air pressure detected by the barometer 54, thereby maintaining a constant negative pressure state during drainage.
[0026] Meanwhile, the airflow and the flow of the accumulated liquid will drive the impeller 46 and the rotating rod 44 to rotate in the rotating hole 43 on the connecting rod 42. When the two impellers 46 rotate, they will also drive the turbulence rope 51 to rotate in the liquid guide tube 52. The drained liquid will enter the drainage bottle 3. At the same time, during drainage, the turbulence component 4 can not only make the accumulated liquid flow smoothly along the liquid guide tube 52, but also prevent pus and blood in the accumulated liquid from clogging the liquid guide tube 52. After the drainage is completed, the drainage bottle 3 can be removed from the fixing ring 21, and the accumulated liquid can be discharged through the drain valve 31. Since the bottom of the inner wall of the drainage bottle 3 is wedge-shaped, the residue of accumulated liquid and cleaning fluid can be reduced during drainage and cleaning. Then the liquid guide tube 52 and the turbulence rope 51 can be removed for cleaning or replacement, thereby improving the convenience of use.
