Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical devices, and more specifically, to a drainage device for oncology medicine. Background Art
[0002] The oncology department is one of the specialized departments in the hospital responsible for diagnosing and treating tumor diseases. It is a medical subject dedicated to treating tumor-related diseases. It mainly targets diagnosed tumor patients for non-surgical treatments such as chemotherapy, targeted therapy, and immunotherapy. The drainage device can drain the liquid that cannot be normally discharged from the patient's body to the outside.
[0003] When the drainage device is draining, in order to prevent the drainage tube from falling off, the drainage tube is generally adhered to the patient's skin by a medical plastic bag. However, using a single plastic bag for adhesion cannot effectively fix the plastic bag. At the same time, the device is generally placed on one side of the hospital bed. If it is hit, it will cause shaking and affect the drainage effect. To solve the above problems, the present invention proposes a drainage device for oncology medicine. Summary of the Invention
[0004] The technical solution adopted by the present invention to solve its technical problems is: a drainage device for oncology medicine, including a housing with an installation shell rotatably installed inside. An airbag is provided inside the installation shell for sucking liquid. A first drainage tube and a second drainage tube are respectively provided at both ends of the airbag for drainage. A one-way valve is provided at the connection between the first drainage tube and the airbag to prevent liquid backflow; A first clamping plate is provided on one inner wall of the housing for squeezing the airbag. Fixed blocks are symmetrically provided on the inner wall of the installation shell. A groove is provided at one end of the fixed block and a push block slides therein. Clamping blocks are provided on the outer wall of the push block for clamping the first drainage tube and the second drainage tube. A chute is provided on the inner wall of the housing and a first spring is provided. The installation shell extends into the chute and abuts against the first spring. A third spring is fixedly connected to the inner wall of the groove, and the third spring is fixedly connected to the push block.
[0005] Specifically, a disc is rotatably installed on the outer wall of the housing. Slide cavities are symmetrically provided inside the installation shell. A top block slides on the inner wall of the slide cavity. A top hole is provided in a circumferential manner on the outer wall of the disc. A tapered block slides inside the slide cavity. The tapered block and the top block are jointly fixed with a second spring.
[0006] Specifically, a circular ring groove is penetrated through the inner wall of the housing at the position corresponding to the tapered block. Tapered push blocks are symmetrically fixed on the outer wall of the installation shell. The tapered block extends into the circular ring groove and abuts against the tapered push block.
[0007] Specifically, an electric push rod is provided on one inner wall of the installation shell. A second clamping plate is fixed at the output end of the electric push rod. The first clamping plate and the second clamping plate are connected to the airbag.
[0008] Specifically, a Velcro is provided on an outer wall of one side of the disc, and the Velcro is connected to the disc via bolts.
[0009] Specifically, the outer shell and the mounting shell are both arranged in a circular shape, so that the mounting shell can rotate inside the outer shell.
[0010] Specifically, one end of the mounting shell located in the slide slot and the slide slot are both arranged in a T shape.
[0011] Specifically, the clamping block is arranged in an arc shape and is connected to the first drainage tube and the second drainage tube ferrule.
[0012] Beneficial effects of the present invention: (1) In the oncology internal drainage device described in the present invention, when the first drainage tube and the second drainage tube are pulled by external force, the clamp block drives the push block to compress the third spring, and the third spring plays a buffering role in the movement of the push block. The fixed block drives the mounting shell to rotate in the shell and compress the first spring. The first spring buffers the rotation of the mounting shell, thereby preventing the first drainage tube from excessively moving due to external force. When the mounting shell rotates, the conical push block symmetrically fixed on its outer wall rotates accordingly, and the conical push block pushes the conical block to move. The conical block moves into the sliding cavity and squeezes the second spring, increasing the elastic force of the second spring, thereby preventing the top block from loosening and moving out of the top hole, ensuring the stable fixing effect of the shell. When the drainage tube is pulled by external force, the buffer structures such as the first spring and the third spring can reduce the impact of external force on the drainage tube and the device as a whole, reduce the risk of displacement and falling off of the drainage tube, and ensure continuous drainage. When the mounting shell rotates, the conical push block pushes the conical block to squeeze the second spring, increasing the elastic force to prevent the top block from loosening, further ensuring the fixing effect of the device, and avoiding the drainage affected by accidental shaking.
[0013] (2) The oncology internal medicine drainage device described in the present invention uses Velcro to fix the device on a bed or a patient's side. The outer shell is rotated, and the outer shell rotates on one side of the disc to adjust the angles of the first drainage tube and the second drainage tube. After adjustment, the second spring pushes the top block to move into the top hole to limit and fix the disc. The first drainage tube is inserted into the patient's wound, and the electric push rod is started to push the second splint to move. The first splint and the second splint squeeze the airbag for drainage. The outer shell can be rotated to adjust the direction of the drainage tube to meet different drainage needs. After adjustment, it can be limited and fixed by the top block and the top hole to ensure stable position during drainage. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.
[0018] As Figures 1-8 shown, the present invention provides the following technical solutions: Embodiment 1: A tumor internal medicine drainage device includes an outer shell 1 with an installation shell 2 rotatably disposed inside. An airbag 3 is provided inside the installation shell 2 for sucking liquid. A first drainage tube 4 and a second drainage tube 5 are respectively provided at both ends of the airbag 3 for drainage. A one-way valve is provided at the connection between the first drainage tube 4 and the airbag 3 to prevent liquid backflow; A first clamping plate 6 is provided on one inner wall of the outer shell 1 for squeezing the airbag 3. Fixed blocks 7 are symmetrically provided on the inner wall of the installation shell 2. A groove is provided at one end of the fixed block 7 and a push block 8 slides therein. A clamping block 9 is provided on the outer wall of the push block 8 for clamping the first drainage tube 4 and the second drainage tube 5. A chute is provided on the inner wall of the outer shell 1 and a first spring 10 is provided. The installation shell 2 extends into the chute and abuts against the first spring 10. A third spring 21 is fixedly connected to the inner wall of the groove, and the third spring 21 is fixedly connected to the push block 8.
[0019] During use, the electric push rod 17 is connected to an external drive source or a storage battery through a controller. The device is fixed to one side of the hospital bed or the patient's body using a magic tape 19. The first drainage tube 4 is inserted into the part of the patient that needs drainage, and the second drainage tube 5 is inserted into the receiver. The electric push rod 17 is activated to push the second splint 18 towards the first splint 6. The first splint 6 and the second splint 18 squeeze the airbag 3. When the electric push rod 17 drives the second splint 18 away from the first splint 6, the airbag 3 expands. During the expansion of the airbag 3, liquid drainage operation is carried out through the first drainage tube 4 and the second drainage tube 5. The outer shell 1 can be rotated. As the outer shell 1 rotates, the orientations of the first drainage tube 4 and the second drainage tube 5 are adjusted. After adjustment, the second spring 15 pushes the top block 12 into the top hole 13 to limit and fix the outer shell 1. When an external force pulls the first drainage tube 4 or the second drainage tube 5, the first drainage tube 4 moves within the mounting shell 2. The first drainage tube 4 drives the clamping block 9 to move. The clamping block 9 drives the push block 8 to compress the third spring 21. The third spring 21 buffers the push block 8. When the push block 8 moves, it simultaneously gives a thrust to the fixing block 7. The fixing block 7 drives the mounting shell 2 to rotate within the outer shell 1 and compresses the first spring 10. The first spring 10 buffers the mounting shell 2, thereby preventing the first drainage tube 4 from moving excessively due to external force. When the second drainage tube 5 is pulled by an external force, the principle is the same as that of the first drainage tube 4. When the mounting shell 2 rotates, it drives the conical push block 16 to rotate. The conical push block 16 pushes the conical block 14 to move into the sliding cavity and squeezes the second spring 15, increasing the elastic force of the second spring 15 to prevent the top block 12 from loosening and moving out of the top hole 13, which affects the fixing effect of the outer shell 1. After use, tear off the magic tape 19 and remove the device.
[0020] Embodiment 2: The technical solutions of this embodiment different from those of Embodiment 1 include: Among them, a disc 11 is rotatably provided on the outer wall of the outer shell 1. The interior of the mounting shell 2 is symmetrically provided with sliding cavities. A top block 12 is slidably provided on the inner wall of the sliding cavity. The outer wall of the disc 11 is circumferentially provided with top holes 13. A conical block 14 is slidably provided inside the sliding cavity. The conical block 14 and the top block 12 are jointly fixed with a second spring 15. The top block 12 and the top holes 13 are both arc-shaped, which is convenient for using the second spring 15 to push the top block 12 into the top hole 13 to limit and fix the outer shell 1.
[0021] Among them, a circular ring groove 20 is penetrated through the outer wall of the outer shell 1 at a position corresponding to the conical block 14. The outer wall of the mounting shell 2 is symmetrically fixed with conical push blocks 16. The conical block 14 extends into the circular ring groove 20 and abuts against the conical push blocks 16. The conical push blocks 16 are arc-shaped, which is convenient for using the conical push blocks 16 to push the conical block 14 to move.
[0022] Among them, an electric push rod 17 is provided on one inner wall of the installation shell 2, and a second clamping plate 18 is fixed to the output end of the electric push rod 17. The first clamping plate 6 and the second clamping plate 18 are connected to the airbag 3, facilitating the use of the electric push rod 17 to push the second clamping plate 18 to press the airbag 3.
[0023] Among them, a magic tape 19 is provided on the outer wall of one side of the disc 11, and the magic tape 19 is connected to the disc 11 by bolts, facilitating the use of the magic tape 19 to fix the device on one side of the hospital bed.
[0024] Among them, both the outer shell 1 and the installation shell 2 are circularly arranged for the installation shell 2 to rotate within the outer shell 1, facilitating the need for the installation shell 2 to rotate within the outer shell 1.
[0025] Among them, one end of the installation shell 2 located in the sliding groove and the sliding groove are both T-shaped, preventing the installation shell 2 from moving randomly within the outer shell 1 and ensuring the stability of its rotation.
[0026] Among them, the clamping block 9 is arc-shaped and is sleeved and connected to the first drainage tube 4 and the second drainage tube 5, facilitating the use of the clamping block 9 to limit the first drainage tube 4 and the second drainage tube 5.
