Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of neurosurgery nursing, and in particular relates to a drainage device. Background Art
[0002] In the surgical treatment of brain trauma, doctors usually use drainage tubes. On the one hand, they can drain the residual blood and gas in the skull to avoid hematoma and bleeding in the brain. On the other hand, they can play a role in controlling the disease and promoting the recovery of the patient's neurological function.
[0003] Chinese patent CN219354814U discloses a drainage device, including a pillar, a trolley is fixedly installed at the bottom of the pillar, a negative pressure device is installed on the top of the other side of the trolley, and an adjusting barrel is fixedly installed on the top of the negative pressure device, and an adjusting rod is installed on the top of the adjusting barrel, and a drainage tube is connected to the other side of the top of the negative pressure device.
[0004] In the above patent, due to the lack of a mechanism for collecting the drainage fluid, the drainage fluid directly enters the negative pressure device, which is inconvenient to judge the drainage volume of the drainage fluid (for example, excessive drainage can cause low intracranial pressure, abnormal brain herniation, intracranial gas accumulation and other problems). At the same time, when the patient lies on the bed, railings are provided at the head and foot of the bed. The above device cannot turn the drainage interface, and the device can only be placed at the end of the bed (when placed on the side of the bed, it is perpendicular to the patient when lying normally, which is inconvenient to connect with the patient). Other patients or medical staff at the end of the bed are likely to touch the device when walking, which is likely to cause the drainage interface to be separated from the patient, reducing the drainage effect. Therefore, a technical measure is proposed to solve the problem that the drainage fluid directly enters the negative pressure device, which is inconvenient to judge the drainage volume of the drainage fluid, the drainage interface cannot be turned, and other patients or medical staff are likely to touch the device when walking, which is likely to cause the drainage interface to be separated from the patient, reducing the drainage effect.

[0032] Reference Figure 1 , Figure 7 As shown, the negative pressure assembly 4 includes a negative pressure cylinder 401, which is slidably fitted with the limiting tube 5, a connecting tube 402 is installed on the side of the negative pressure cylinder 401, and the connecting tube 402 is connected to the hose, and an adjusting cylinder 404 is installed on the upper end of the negative pressure cylinder 401, and a vertical rod 405 is slidably passed through the upper end of the adjusting cylinder 404, a push block 406 is connected to the upper end of the vertical rod 405, and a sealing gasket 403 is connected to the lower end of the vertical rod 405, and the sealing gasket 403 is slidably fitted with the adjusting cylinder 404, and the push block 406 is pulled upward to move the sealing gasket 403 upward to reduce the air pressure of the negative pressure device, and the accumulated fluid continues to flow.
[0033] Working principle: When draining the patient, the patient lies on the bed with an inclination, and the device is pushed to the side of the bed, close to the side of the bed, and the device is fixed by the moving wheel 9 (the moving wheel 9 has a brake function), and then the drainage tube 10 is installed on the lifting component 3, and the other end of the drainage tube 10 is connected to the telescopic hose 14. When installing the drainage tube 10, one hand pushes the drainage tube 10 into the sleeve 305, and one hand compresses the silicone pad 304, and the silicone pad 304 moves toward the direction close to the column 13. When the silicone pad 304 moves, it drives the clamping rod 307 to compress the second spring 309. After the drainage tube 10 completely enters the sleeve 305, the silicone pad 304 is released, and the first spring 205 rebounds to drive the silicone pad 304 to contact the drainage tube 10, thereby completing the fixation of the drainage tube 10;
[0034] Then, the turntable 6 is rotated to drive the drainage tube 10 to the same angle as the patient's lying down inclination. The specific method is to pull the pull plate 201 to drive the connecting rod 202 to move, and the connecting rod 202 moves to drive the pressing plate 203 and the round rod 204 to move. When the pressing plate 203 moves, the first spring 205 is compressed, and the round rod 204 moves away from the round hole 8 to release the limit of the turntable 6. The turntable 6 is rotated to drive the column 13 to rotate, and the rotation of the column 13 drives the drainage tube 10 to rotate. When the drainage tube 10 and the patient are tilted at the same angle, the pull plate 201 is released and the round rod 204 is driven to insert into the round hole 8 under the rebound action of the first spring 205 (in actual use, the round holes 8 can be arranged more densely);
[0035] At this time, the lifting component 3 is used to adjust the height of the drainage tube 10, and the turning handle 301 drives the screw rod 302 to rotate, and the screw rod 302 drives the lifting plate 303 to move up and down along the slide groove 7, and the lifting plate 303 moves up and down to drive the sleeve 305 to move up and down, and the sleeve 305 moves up and down to drive the drainage tube 10 to move up and down. When it is adapted to the height of the patient lying down, the rotating knob 12 drives the threaded rod to press against the screw rod 302 to complete the height fixation of the drainage tube 10, and connect the drainage tube 10 to the drainage interface buried in the patient's head (a drainage interface will be left after the operation to facilitate drainage). Under the influence of the high intracranial pressure, the effusion enters the drainage tube 10 and then enters the drainage bottle 15. When it is observed that the drainage volume has been reached, the drainage is stopped;
[0036] During drainage, when the accumulated fluid does not flow, the push block 406 is pulled upward to move the sealing pad 403 upward to reduce the air pressure of the negative pressure device, and the accumulated fluid continues to flow. After the drainage is completed, the drainage fluid is taken for testing (such as protein content, cell count, etc.), the drainage tube 10 is replaced, and a new drainage tube 10 and drainage bottle 15 are replaced to continue drainage for the remaining patients.
[0037] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
