[0002] Oncology, like internal medicine, surgery, obstetrics and gynecology, and pediatrics, is a secondary discipline of clinical medicine. It is divided into internal oncology, tumor radiotherapy, and tumor surgery. The internal oncology department is mainly engaged in the internal medical treatment of various benign and malignant tumors. Patients with tumors may have malignant effusions in their bodies. In order to alleviate the patient's pain, it is usually necessary to drain the malignant effusions in the body. Therefore, a drainage device is needed.
[0003] For example, an existing patent (publication number: CN215994984U) discloses an oncology internal medicine drainage device. By turning on the negative pressure vacuum pump, the negative pressure vacuum pump suctions the drainage tube. The drainage tube uses a drainage ball to drain the patient's pleural effusion, and then discharges it into the drainage box through the drainage tube.
[0004] However, the oncology internal medicine drainage device designed above still has some disadvantages in practical application: although the oncology internal medicine drainage device can facilitate drainage work, only a base is provided at the bottom, which makes the stability of the drainage device poor. Since there are many patients or family members in the hospital, the drainage device is usually placed under the bed to form a height difference with the patient's body, which makes it possible for people around to knock over the drainage device due to scratches, and the drainage device may pull the drainage tube, thereby causing secondary damage to the patient's wound.
[0005] Therefore, we designed an oncology drainage device to solve the above problems. Utility Model Content

[0023] The embodiments of the present utility model will be described in detail below.
[0024] Embodiment 1
[0025] Consisting of Figures 1-4A drainage device for tumor internal medicine is provided, comprising a drainage cup 1, a drainage tube 2 is inserted at the top of the drainage cup 1, a positioning base 3 is fixedly installed at the bottom of the drainage cup 1, a negative pressure groove 4 is provided at the bottom of the positioning base 3, a fixed cavity 5 is provided in the positioning base 3, an exhaust pipe 6 is fixedly inserted at one side of the positioning base 3, one end of the exhaust pipe 6 is connected to the fixed cavity 5 and is provided with a one-way exhaust valve 7, a one-way air inlet valve 8 is provided in the fixed cavity 5, the one-way air inlet valve 8 is connected to the negative pressure groove 4, a piston 9 is slidably connected in the fixed cavity 5, and the fixed cavity 5 is rotatably provided with a rotating shaft 10, a rotating disk 11 is fixedly sleeved on the rotating shaft 10, and the rotating disk 11 is transmission-connected with the piston 9. A motor 12 is provided on the outer surface of the positioning base 3, and a driving shaft of the motor 12 is transmission-connected with one end of the rotating shaft 10. A mounting seat 13 is provided on one side of the piston 9, and a transmission shaft 15 is provided on the front side of the rotating disk 11. A rotating member 14 is rotatably sleeved on the transmission shaft 15, and the other end of the rotating member 14 is rotationally connected with the mounting seat 13. A pin is provided in the mounting seat 13, and the rotating member 14 is rotatably sleeved on the pin.
[0026] During the specific implementation, the drainage cup 1 is placed at a suitable position under the patient's bed, and then the motor 12 is turned on to make the rotating shaft 10 drive the turntable 11 to rotate, so that the transmission shaft 15 drives the rotating member 14 to rotate and push the piston 9 to reciprocate in the fixed chamber 5. In this process, the one-way air intake valve 8 can be used to suck the air between the ground and the negative pressure groove 4 into the fixed chamber 5, and then the one-way exhaust valve 7 is used to discharge the air sucked into the fixed chamber 5 out of the positioning base 3. At this time, negative pressure can be generated in the negative pressure groove 4, and the drainage cup 1 and the positioning base 3 can be positioned on the ground by atmospheric pressure, which can improve the stability of the drainage device and avoid the problem of pulling the drainage tube 2 due to the dumping of the drainage device.
[0027] The bottom of the positioning base 3 is provided with a sealing ring 16. Since tiles are usually laid in the ward, and the surface of the tiles is relatively smooth, the gap between the negative pressure tank 4 and the ground can be filled by the sealing ring 16, thereby ensuring the sealing performance.
[0028] The one-way exhaust valve 7 and the one-way air intake valve 8, also known as a check valve or a non-return valve, are usually composed of a valve body, a valve plate and a valve membrane. The principle is: when the gas generated by the items sealed in the bag causes the bag to reach a certain pressure, the gas can push the exhaust valve plate from the inside to the outside (from the outside to the inside) and lead the gas to the (inside) and outside; when the pressure in the bag is reduced to a level that is not enough to push open the valve plate, the valve automatically closes and outside air cannot enter the bag. Since the one-way exhaust valve 7 and the one-way air intake valve 8 are both existing technologies, they will not be explained in detail in this manual.
[0029] Embodiment 2
[0030] Depend on Figures 1-4Provided is a drainage device for oncology, comprising a drainage tank 1. A drainage tube 2 is inserted into the top of the drainage tank 1. A positioning base 3 is fixedly installed at the bottom of the drainage tank 1. A negative pressure groove 4 is formed at the bottom of the positioning base 3. A fixing cavity 5 is formed inside the positioning base 3. One side of the positioning base 3 is fixedly plugged with an exhaust pipe 6. One end of the exhaust pipe 6 is communicated with the fixing cavity 5 and is provided with a one-way exhaust valve 7. A one-way intake valve 8 is arranged inside the fixing cavity 5. The one-way intake valve 8 is communicated with the negative pressure groove 4. A piston 9 is slidably connected inside the fixing cavity 5. A rotating shaft 10 is rotatably arranged inside the fixing cavity 5. A turntable 11 is fixedly sleeved on the rotating shaft 10. The turntable 11 is in transmission connection with the piston 9. A motor 12 is arranged on the outer surface of the positioning base 3. The driving shaft of the motor 12 is in transmission connection with one end of the rotating shaft 10. A C-shaped frame 17 is fixedly installed at the rear side of the drainage tank 1. A hand-tightening bolt 18 is threadedly inserted into the bottom of the C-shaped frame 17. A positioning plate 19 is arranged at the end of the hand-tightening bolt 18. The positioning plate 19 is located inside the C-shaped opening of the C-shaped frame 17.
[0031] During specific implementation, on the basis of Embodiment 1, if it is necessary to install the drainage device on a patient's hospital bed, first release the negative pressure positioning of the drainage tank 1, then drive the C-shaped frame 17 with the drainage tank 1 to be clamped at the corner of the patient's hospital bed, and then rotate the hand-tightening bolt 18, so that the hand-tightening bolt 18 can drive the positioning plate 19 to rotate and move until the positioning plate 19 abuts against the hospital bed corner, which can facilitate the installation of the drainage device on the hospital bed and further improve the positioning effect of the drainage device.
[0032] The end of the hand-tightening bolt 18 away from the end is provided with anti-slip threads, which can increase the friction between the human hand and the hand-tightening bolt 18, thereby helping to solve the problem of slipping when the human rotates the hand-tightening bolt 18.
[0033] A sealing cylinder 20 is fixedly installed at the top of the drainage tank 1. The drainage tube 2 is movably inserted into the inner circle of the sealing cylinder 20 and extends into the drainage tank 1. The sealing cylinder 20 is made of rubber. Since rubber has a certain friction, it can simply limit the drainage tube 2 and facilitate the drainage of the patient.
[0034] A 21 is arranged on the front side of the drainage tank 1, which is convenient for medical staff to observe the amount of drainage fluid in the drainage tank 1.
[0035] Working principle:
[0036] When in use, first place the drainage can 1 at a suitable position under the patient's bed, then turn on the motor 12, so that the rotating shaft 10 drives the turntable 11 to rotate, so that the transmission shaft 15 drives the rotating member 14 to rotate while pushing the piston 9 to reciprocate in the fixed chamber 5. In this process, the one-way air intake valve 8 can be used to suck the air between the ground and the negative pressure groove 4 into the fixed chamber 5, and then the one-way exhaust valve 7 is used to discharge the air sucked in the fixed chamber 5 out of the positioning base 3. At this time, negative pressure can be generated in the negative pressure groove 4, and the drainage can 1 can be drained by atmospheric pressure. By positioning the positioning base 3 on the ground, the stability of the drainage device can be improved, and the problem of pulling the drainage tube 2 due to the drainage device tipping over can be avoided. If the drainage device needs to be installed on the patient's bed, first, the drainage can 1 drives the C-shaped frame 17 to engage with the corner of the patient's bed, and then the hand-tightening bolt 18 is rotated, so that the hand-tightening bolt 18 can drive the positioning plate 19 to rotate and move until the positioning plate 19 is against the corner of the bed. The drainage device can be conveniently installed on the bed, and the positioning effect of the drainage device can be further improved.
