Description

Technical Field

[0001] This utility model relates to the field of tumor treatment technology, specifically to a fluid drainage device for use in oncology. Background Technology

[0002] A tumor is a new growth formed by the proliferation of local tissue cells under the influence of various carcinogenic factors. Because these new growths often present as space-occupying, mass-like protrusions, they are also called growths. Liver cancer and pancreatic cancer are both known as the "kings of cancers," being highly malignant tumors. Patients with advanced malignant tumors often have poor appetites, high bodily consumption, and low tissue osmotic pressure, frequently leading to ascites. Large amounts of protein leak into the abdominal cavity, causing hypoproteinemia. Simultaneously, the increased ascites compresses the stomach, causing a feeling of fullness, further affecting appetite. This further decrease in protein stimulates accelerated ascites growth, creating a vicious cycle. Therefore, it is often necessary to drain these effusions clinically.

[0003] Generally, tumor fluid is drained multiple times using syringes, indwelling needles, etc. During drainage, medical staff need to pull the plunger of the syringe. Due to the negative pressure, pulling is difficult and can easily cause the syringe to become unstable, which can be dangerous. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a fluid drainage device for oncology departments, which overcomes the deficiencies of existing technologies. It aims to solve the problem that when draining tumor fluid, multiple drainage processes are required through needles, indwelling needles, etc. During drainage, medical staff need to pull the piston handle of the needle. Due to the negative pressure, pulling is difficult and can easily lead to needle instability and dangerous situations.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fluid drainage device for oncology, comprising a suction mechanism and a retention mechanism, wherein the suction mechanism is installed on the retention mechanism;

[0006] The liquid extraction mechanism includes a liquid extraction tube, a first limiting ring, a second limiting ring, a first slot, a notched ring, a lead screw, a bracket, a motor, and a lifting plate. The first limiting ring and the second limiting ring are both fixedly connected to the outer wall of the liquid extraction tube. The first slot is formed on the second limiting ring. The notched ring is disposed between the first limiting ring and the second limiting ring. The lead screw is rotatably connected to the lead screw, and the other end of the lead screw is rotatably connected to the bracket. The motor is bolted to the bracket, and the output shaft of the motor is welded to one end of the lead screw. The lifting plate is threadedly connected to the lead screw.

[0007] As a preferred embodiment of this utility model, a piston rod is slidably connected inside the liquid extraction tube, and a piston handle is fixedly connected to one end of the piston rod, with a second groove provided on the piston handle.

[0008] As a preferred embodiment of this utility model, a guide rod is welded to one side of the bracket, one end of the guide rod passes through the lifting plate and is slidably connected to the lifting plate, and a fixing plate is welded to the end of the guide rod away from the bracket.

[0009] As a preferred embodiment of this utility model, a sliding cylinder is slidably connected to the outer wall of the first limiting ring, and one end of the liquid extraction tube is connected to a pipe connector, on which a needle is installed.

[0019] Please see Figure 1-3 A fluid drainage device for use in oncology includes a fluid aspiration mechanism and an indwelling mechanism. The fluid aspiration mechanism is installed on the indwelling mechanism. The fluid aspiration mechanism is used to assist medical staff in aspirating fluid, and the indwelling mechanism is used to insert an indwelling catheter 23 for easy re-infusion or aspiration.

[0020] Reference Figure 1 and Figure 2The liquid extraction mechanism includes a liquid extraction tube 11, a first limiting ring 12, a second limiting ring 13, a first slot 14, a notched ring 15, a lead screw 16, a bracket 17, a motor 18, and a lifting plate 19. The first limiting ring 12 and the second limiting ring 13 are both fixedly connected to the outer wall of the liquid extraction tube 11. The outer diameters of the first limiting ring 12 and the second limiting ring 13 are the same. A sliding cylinder 116 is slidably connected to the outer wall of the first limiting ring 12. The sliding cylinder 116 can move between the first limiting ring 12 and the second limiting ring 13. The notched ring 15 is fixed by sliding on the ring 13, preventing it from dislodging from between the first limiting ring 12 and the second limiting ring 13. Then, the upper end of the lead screw 16 is engaged in the first slot 14 to fix the notched ring 15. The first slot 14 is formed on the second limiting ring 13, and the notched ring 15 is positioned between the first limiting ring 12 and the second limiting ring 13. The lead screw 16 is rotatably connected to the bracket 17, and the other end of the lead screw 16 is rotatably connected to the bracket 17. The motor 18 is mounted by bolts. On the bracket 17, the output shaft of the motor 18 is welded to one end of the lead screw 16. The lifting plate 19 is threaded onto the lead screw 16. A piston rod 113 is slidably connected inside the suction tube 11. One end of the piston rod 113 is fixedly connected to a piston handle 114. A second slot 115 is provided on the piston handle 114. The thread of the lead screw 16 is disposed in the second slot 115. By gripping the slide cylinder 116 by hand, the notched ring 15, the lead screw 16, the bracket 17, and the motor 18 are fixed. When the pump is in use, the motor 18 is started by controlling the switch. The motor 18 drives the lead screw 16 to rotate, which causes the lifting plate 19 to move up and down. When the lifting plate 19 moves down, it will drag the piston handle 114 down, thereby slowly and stably extracting the accumulated liquid, which is safer. If it needs to be reset, it is only necessary to manually push the piston handle 114. After use, the notched ring 15, lead screw 16, bracket 17 and motor 18 can be removed by sliding the slide cylinder 116. The liquid extraction tube 11 can be reused while being discarded, saving costs.

[0021] For details, please refer to Figure 2 A guide rod 110 is welded to one side of the bracket 17. One end of the guide rod 110 passes through the lifting plate 19 and is slidably connected to the lifting plate 19. A fixing plate 111 is welded to the end of the guide rod 110 away from the bracket 17. The guide rod 110 is used to guide the lifting plate 19 to move up and down.

[0022] For details, please refer to Figure 1-3 One end of the suction tube 11 is connected to a tube connector 112, and a needle 117 is installed on the tube connector 112. The needle 117 is used to assist in guiding the catheter 23 into the human body. After being withdrawn, the catheter 23 remains in the human body.

[0023] For details, please refer to Figure 3The indwelling device includes a three-way tube 21, an isolation plug 22, a catheter 23, and a needle holder 24.

One end of the needle 117 is inserted into the isolation plug 22 and extends along the inner wall of the catheter 23. The isolation plug 22 prevents external bacteria from entering the three-way tube 21, making it more hygienic. The needle holder 24 assists medical personnel in holding the device. An extension tube 25 is connected to the three-way tube 21, and a positive pressure connector 26 is installed at one end of the extension tube 25. When medication needs to be injected into the human body, it can be injected through the positive pressure connector 26.

[0024] Working principle: The threaded part of the lead screw 16 is disposed in the second slot 115. By gripping the slide cylinder 116 by hand, the notched ring 15, lead screw 16, bracket 17 and motor 18 are fixed. In use, the motor 18 is started by controlling the switch. The motor 18 drives the lead screw 16 to rotate, causing the lifting plate 19 to move up and down. When the lifting plate 19 moves down, it will drag the piston handle 114 down, thereby slowly and stably extracting the accumulated liquid, which is safer. If it needs to be reset, it is only necessary to manually push the piston handle 114. After use, the notched ring 15, lead screw 16, bracket 17 and motor 18 can be removed by sliding the slide cylinder 116. They can be reused while discarding the liquid extraction tube 11, saving costs.
