Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical auxiliary equipment technology, and in particular relates to a drainage device for cardiothoracic surgery that is easy to fix and prevents blockage. Background Technology
[0002] Cardiothoracic surgery drainage devices are medical devices specifically designed for draining pleural effusion, blood, or gas after surgery or trauma. They aim to prevent and treat potential complications. The device typically consists of a drainage tube, collection bag or bottle, valve, and connecting devices. It can effectively drain body fluid from the pleural cavity to reduce intrathoracic pressure, improve respiratory function, and promote postoperative recovery. The design of the drainage device takes into account biocompatibility, anti-clogging performance, and ease of operation to ensure safety and effectiveness in clinical use.
[0003] In existing cardiothoracic surgery drainage devices, the accumulated drainage fluid inside the collection device needs to be drained periodically. This process often leads to the collection device being unstable during fixation and prone to displacement. This displacement not only affects the stability of the drainage device but may also negatively impact the drainage effect of the drainage tube. At the same time, existing drainage devices are prone to blockage during drainage. This blockage not only hinders normal drainage but may also cause discomfort to the patient.
[0004] To address these issues, we provide a cardiothoracic surgical drainage device that is easy to fix and prevents blockage. Utility Model Content
[0005] The purpose of this invention is to provide a drainage device for cardiothoracic surgery that is easy to fix and prevents blockage. By combining the drainage component and the drainage component, it solves the problems of existing drainage devices for cardiothoracic surgery, such as the inconvenience of timely drainage of collected body fluids and the easy blockage of the drainage tube.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] This utility model relates to a drainage device for cardiothoracic surgery that is easy to fix and prevents blockage. It includes a collection bottle with a processing bottle at its bottom and a drainage tube connected to one side of the top of the collection bottle. A drainage assembly is located at the bottom of the collection bottle, including a spring rod fixedly connected to both sides of the bottom of the collection bottle.

An mounting component is located on one side of the surface of the collection bottle. A drainage assembly is located at one end of the drainage tube, including a drainage tube connected to one end of the drainage tube. A fixing block is fixedly connected to the surface of the drainage tube, and medical tape is adhered to one side of the fixing block. A cross-shaped anti-blockage bracket is fixedly connected to one side of the inner cavity of the drainage tube.
[0008] The present invention is further configured such that the mounting component includes a clamping frame, the clamping frame is fixedly connected to one side of the surface of the collection bottle, a threaded pin is threadedly connected to the top of the inner cavity of the clamping frame, and a magnet is fixedly connected to the bottom of the inner cavity of the clamping frame.
[0009] The present invention is further configured such that a liquid pump is fixedly connected to one side of the top of the collection bottle, the input end of the liquid pump is connected to an air inlet pipe, and one end of the air inlet pipe extends into the inner cavity of the collection bottle.
[0010] The present invention is further configured such that a drain pipe is connected to the bottom of the collection bottle, one end of the drain pipe is in contact with the top of the treatment bottle, and a solenoid valve is installed on the surface of the drain pipe.

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments. Specific Implementation Example 1
[0027] Please see Figure 1-5 This utility model is a drainage device for cardiothoracic surgery that is easy to fix and prevents blockage. It includes a collection bottle 1, a processing bottle 2 at the bottom of the collection bottle 1, and a guide tube 3 connected to one side of the top of the collection bottle 1. A drainage component is provided at the bottom of the collection bottle 1, which includes a spring rod 4. The spring rod 4 is fixedly connected to both sides of the bottom of the collection bottle 1. An inclined block 5 is fixedly connected to the free end of the spring rod 4. A pull rod 6 is fixedly connected to one side of the inclined block 5. Limiting blocks 7 are fixedly connected to both sides of the top of the processing bottle 2. The inner cavity of the limiting block 7 is slidably connected to one side of the inclined block 5. An installation part is provided on one side of the surface of the collection bottle 1. A drainage component is provided at one end of the guide tube 3. The drainage component includes a drainage tube 8, which is connected to one end of the guide tube 3. A fixing block 9 is fixedly connected to the surface of the drainage tube 8. Medical tape 10 is bonded to one side of the fixing block 9. A cross anti-blockage bracket 11 is fixedly connected to one side of the inner cavity of the drainage tube 8.
[0028] Specifically: The top side of the inner cavity of the collection bottle 1 is connected to one end of the drainage tube 3 to facilitate the delivery of the drained body fluid to the collection bottle 1. The surface of the treatment bottle 2 is transparent and has scale lines to facilitate medical staff to observe the amount of drained body fluid and to drain the collected body fluid in a timely manner. When the two pull rods 6 are pulled to the sides of the collection bottle 1, the inclined block 5 can separate from the limiting port opened in the inner cavity of the limiting block 7, releasing the limitation on the treatment bottle 2. The cross anti-blocking bracket 11 can prevent the small hole from being blocked by tissue or other substances, ensuring smooth drainage. Specific Implementation Example 2
[0030] Please see Figure 1-5 Based on the first specific embodiment, the mounting component includes a clamping frame 12, which is fixedly connected to one side of the surface of the collection bottle 1. A threaded pin 13 is threadedly connected to the top of the inner cavity of the clamping frame 12, and a magnet 14 is fixedly connected to the bottom of the inner cavity of the clamping frame 12. A liquid pump 15 is fixedly connected to one side of the top of the collection bottle 1. An air inlet pipe 16 is connected to the input end of the liquid pump 15. One end of the air inlet pipe 16 extends into the inner cavity of the collection bottle 1. A drain pipe 17 is connected to the bottom of the collection bottle 1. One end of the drain pipe 17 contacts the top of the processing bottle 2. A solenoid valve 18 is installed on the surface of the drain pipe 17. A drain head is connected to one end of the drain pipe 8. A round hole is opened on the surface of the drain head. Slots are opened on both sides of the bottom of the collection bottle 1. One end of the spring rod 4 is fixedly connected to one side of the inner cavity of the slot. Slide grooves are opened on both sides of the bottom of the surface of the collection bottle 1. One end of the pull rod 6 extends to the outside of the collection bottle 1 through the inner cavity of the slide groove.
[0031] Specifically: The clamping frame 12 is usually clamped to the side of the patient's bed and connected to the bed frame. The inner bottom of the frame can be attracted to the bottom of the bed by the magnet 14, and the clamping frame 12 is fixed by the threaded pin 13. The output end of the suction pump 15 is located at the rear of the suction pump 15. The suction pump 15 can absorb and discharge the gas in the collection bottle 1 to create a negative pressure in the collection bottle 1, so that the drainage tube 8 can guide the body fluid to the collection bottle 1. When the solenoid valve 18 is opened, the body fluid in the collection bottle 1 can flow to the treatment bottle 2. When the solenoid valve 18 is closed, the treatment bottle 2 can be removed to drain the body fluid, while the body fluid that is still draining is temporarily stored in the collection bottle 1. The multiple round holes on the surface of the drainage head can increase the drainage area.
[0032] The working principle of this utility model is as follows: When it is necessary to drain body fluid from a patient with a cardiothoracic shell, firstly, the clamping frame 12 on one side of the collection bottle 1 is installed next to the patient's bed. Then, the bottom of the collection bottle 1 is attracted to the bottom of the bed frame by the magnet 14, and the clamping frame 12 is fixed to one side of the bed frame by turning the threaded pin 13. Then, one end of the drainage tube 8 is inserted into the patient's body, and the drainage tube 8 is fixed by the medical tape 10 on one side of the fixing block 9. Next, the external controller starts the suction pump 15. The suction pump 15 discharges the gas in the collection bottle 1 through the air inlet pipe 16 and the output end, so that the collection bottle 1 generates negative pressure, thereby draining the patient's body fluid into the collection bottle 1 through the drainage tube 8 and the guide tube 3. During drainage, the cross anti-blocking bracket 11 can prevent the small hole from being blocked by tissue or other substances, ensuring smooth drainage.
[0033] The bodily fluid in collection bottle 1 flows to treatment bottle 2 through drain pipe 17. When the bodily fluid in treatment bottle 2 reaches a certain amount, drain pipe 17 is closed by solenoid valve 18. Then, pull rod 6 is pulled, which moves inclined block 5, causing inclined block 5 to release the limit block 7. Then, treatment bottle 2 is taken out to drain the bodily fluid. Finally, treatment bottle 2 is inserted back into the bottom of collection bottle 1, and solenoid valve 18 is opened to collect the temporarily stored bodily fluid in collection bottle 1.
