Detailed Description

The invention will be further explained with reference to the following figures and examples:

as shown in fig. 1 and 2, the utility model discloses a drainage device for cardiovascular medicine, including drainage subassembly 1 and drainage tube, the drainage tube includes urceolus 6 and inner tube. The inner cylinder comprises a cylinder body 3 and an end cover 2, the end cover 2 seals the upper end of the outer cylinder 6, and the lower end of the outer cylinder 6 is opened. The lower end of the inner cylinder is closed, and the upper end of the inner cylinder is open. The outer wall of the inner cylinder is provided with internal threads, the inner wall of the outer cylinder 6 is provided with external threads, the outer cylinder 6 is sleeved on the inner cylinder from bottom to top, and the outer cylinder 6 is in threaded fit with the internal threads on the outer wall of the inner cylinder through the external threads. As shown in figure 1, the outer cylinder 6 and the inner cylinder are coaxially arranged, and the drainage component 1 is communicated with the inside of the inner cylinder through the end cover 2. The end cover 2 and the barrel 3 are also in threaded connection.

As shown in fig. 1, a plugging structure is provided inside the outer cylinder 6, and the plugging structure includes a connecting rod 7 and a plugging body, and the plugging body includes a plugging disc 4 and a rubber seal 5. The connecting rod 7, the plugging body, the plugging disc 4 and the outer cylinder 6 are all coaxially arranged. The lower extreme of connecting rod 7 rotates with the bottom of urceolus 6 to be connected, and shutoff dish 4 fixed connection is in the upper end of connecting rod 7, and rubber seal 5 suits are on the outer lane of shutoff dish 4. The plugging body is positioned in the inner barrel and is in sliding seal with the inner barrel wall of the inner barrel through a rubber sealing ring 5. The sliding seal described in the present embodiment means: when the plugging disc 4 moves up and down in the inner cylinder, the plugging body and the cylinder wall of the inner cylinder are always in a sealed state under the sealing action of the rubber sealing ring 5, which is also used for preventing the liquid in the inner cylinder from leaking into the outer cylinder 6 from the plugging body.

When in specific use: normally, a closed cavity 31 is formed by the blocking body, the end cap 2 and the barrel 3, and the cavity 31 is used for containing liquid or blood of a patient. When the volume of the cavity 31 needs to be increased, the outer cylinder 6 is rotated, and the outer cylinder 6 is in threaded connection with the inner cylinder, so that the outer cylinder 6 pulls the blocking structure from the outer cylinder 6 to the opposite direction of the end cover 2 when descending along the cylinder body 3 of the inner cylinder, namely, downwards as shown in fig. 1. The outer barrel 6 is rotated, the outer barrel 6 pushes the connecting rod 7, so that the connecting rod 7 pulls the plugging disc 4 upwards and downwards, the volume of the cavity 31 formed by the plugging body, the end cover 2 and the barrel body 3 of the content is increased or reduced continuously until the requirement of liquid storage can be met.

For the present case, the rubber seal ring 5 has a sealing function on the one hand; on the other hand, the rubber packing 5 moves in the inner cylinder to clean the inner wall of the inner cylinder because the leg packing has elasticity. Therefore, the rubber seal ring 5 should be replaced periodically during use to prevent leakage and accumulation of residues due to excessive wear of the rubber seal ring 5. In the optimized embodiment, the upper end of the connecting rod is provided with two plugging bodies, and the lower end of the inner barrel is sealed by the two plugging bodies so as to further prevent the leakage of the plugging bodies.

As another optimization, the lower part of the barrel 3 of the inner barrel is also provided with a threaded hole 32 along the radial direction, and the threaded hole 32 penetrates through the barrel wall of the barrel 3. When the volume of the cavity 31 in the inner barrel is continuously increased and cannot meet the needs of individual special patients, as shown in fig. 2, a drainage pipeline 8 can be connected to the threaded hole 32 in advance, and part of liquid is discharged into the garbage can through the drainage pipeline 8. When the residual liquid can be stored in the inner cylinder, the outer cylinder 6 is rotated reversely, and the cavity 31 is sealed by the sealing body. In the scheme, the threads for connection are all fine threads so as to realize leakage prevention.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
