[0030] Please see Figure 1-6 This utility model provides a technical solution: a thyroid negative pressure drainage device, including a base plate 1, with a pressure sensor 2 and an alarm mechanism 3 fixed at both ends of the upper surface of the base plate 1, a base plate 4 fixedly disposed on the upper surface of the pressure sensor 2, a collection box 5 movably connected to one side of the base plate 4, a clip 6 fixedly installed on the upper surface of the other side of the base plate 4, and a limit mechanism 7 disposed on the upper surface of the base plate 4 on the side of the clip 6.
[0031] The upper outer wall of the collection box 5 is fitted with a cover plate 8, the inner wall of the cover plate 8 is fixedly connected with a sealing gasket 9, the inner wall of the end of the cover plate 8 is movably connected with a first pipe head 10, a vacuum pump 11 is fixedly installed on the upper surface of the cover plate 8 on the side of the first pipe head 10, and a limit bridge 12 is fixedly installed on the upper surface of the cover plate 8 on the side of the vacuum pump 11.
[0032] One end of a conduit 13 is fixedly connected to the inner wall of the first tube head 10. A second tube head 14 is fixedly installed on the outer wall of the other end of the conduit 13. An end cap 15 is fitted on the outer wall of the second tube head 14. A sealing gasket 16 is bonded to the inner wall of the end cap 15. A collection cylinder 17 is threadedly installed on the inner wall of the end cap 15 below the sealing gasket 16. A filter cylinder 18 is installed inside the collection cylinder 17. A positioning ring 19 is fixedly connected to the lower outer wall of the filter cylinder 18. The inner wall of the middle part of the end cap 15 is connected to one end of the drainage tube 20 through the second tube head 14. A drainage needle 21 is installed on the other end of the drainage tube 20.
[0033] In this example, the pressure sensor 2 and the alarm mechanism 3 are electrically connected, so that when the gravity on the pressure sensor 2 exceeds the threshold, the pressure sensor 2 sends a signal to the alarm mechanism 3. At this time, the alarm mechanism 3 will sound an alarm to remind the staff that the collection box 5 is full and needs to be replaced, thereby improving the ease of use of the device.
[0034] In this example, the collection box 5 forms a sliding structure with the substrate 4 and the cover plate 8 respectively. The collection box 5 and the sealing gasket 9 are in contact, which facilitates the sliding of the cover plate 8 relative to the collection box 5 for the installation and removal of the cover plate 8, and also facilitates the sliding of the collection box 5 relative to the substrate 4 for the installation and removal of the collection box 5, and improves the sealing performance of the cover plate 8 when it is closed by the sealing gasket 9.
[0035] In this example, the limiting mechanism 7 includes a limiting arm 701, a sleeve 702, and a limiting button 703. The limiting arm 701 is movably mounted on the upper surface of the substrate 4. The upper end of the limiting arm 701 is fixedly connected to the sleeve 702. The inner wall of the sleeve 702 is movably provided with the limiting button 703, so that the cover plate 8 can be stably installed on the collection box 5 through the limiting mechanism 7.
[0036] In this example, the limiting arm 701 and the base plate 4 form a rotating structure. The limiting arm 701 and the clamp 6 are fitted together. The sleeve 702 and the limiting button 703 are threaded together. The limiting button 703 and the limiting bridge 12 are slidably arranged, which makes it easy for the operator to rotate the limiting arm 701 so that the limiting arm 701 fits against the clamp 6. At this time, the limiting button 703 moves above the limiting bridge 12. So when the operator tightens the limiting button 703, the limiting button 703 moves down relative to the sleeve 702 and inserts into the limiting bridge 12. As the operator continues to tighten the limiting button 703, the limiting button 703 presses against the limiting bridge 12, so that the limiting bridge 12 presses against the cover plate 8 and stably installs it on the collection box 5.
[0037] In this example, the first tube head 10 and the cover plate 8 are threaded together, the second tube head 14 and the end cap 15 are threaded together, and the second tube head 14 and the drainage tube 20 are fixedly connected. This facilitates the rotation of the first tube head 10 and the second tube head 14 to disassemble the catheter 13 and the drainage tube 20, and improves the stability of the connection between the drainage tube 20 and the end cap 15.
[0038] In this example, both the collection cylinder 17 and the filter cylinder 18 are fitted together with the sealing gasket 16. The collection cylinder 17 and the positioning ring 19 are slidably arranged so that when the operator tightens the end cap 15, the end cap 15 is tightly fitted to the collection cylinder 17 and the filter cylinder 18, thereby completing the seal between the collection cylinder 17 and the filter cylinder 18. It also makes it easy for the operator to disassemble and assemble the filter cylinder 18, as the filter cylinder 18 drives the positioning ring 19 to slide relative to the collection cylinder 17.
[0039] Working principle: According to Figure 1-6 As shown, the staff places the base plate 1 on the table, then inserts the drainage needle 21 into the patient's drainage site. Next, the staff starts the vacuum pump 11, which then evacuates the collection box 5, creating negative pressure within the collection box 5. This negative pressure then forms in the catheter 13, collection cylinder 17, drainage tube 20, and drainage needle 21. The fluid around the patient's thyroid gland then flows into the collection cylinder 17 through the drainage needle 21 and drainage tube 20. At this point, the filter cylinder 18 filters the fluid flowing into the collection cylinder 17, allowing solid impurities in the fluid to accumulate. In the filter cartridge 18, to avoid clogging and affecting the normal operation of the device, the filtered fluid flows through the conduit 13 into the collection box 5, thus completing the negative pressure drainage of the thyroid fluid. Then, when the gravity on the pressure sensor 2 exceeds the threshold, the pressure sensor 2 sends a signal to the alarm mechanism 3. At this time, the alarm mechanism 3 sounds an alarm to remind the staff that the collection box 5 is full and needs to be replaced, thereby improving the ease of use of the device. After the device is used, the staff turns off the vacuum pump 11 and moves the device to the cleaning area. At this time, the staff rotates and disassembles the first tube head. 10 and the second tube head 14 are used to complete the disassembly of the catheter 13, drainage tube 20, and drainage needle 21. Next, the operator rotates the end cap 15 to disengage the end cap 15 and sealing gasket 16 from the collection cylinder 17. Then, the operator pulls out the filter cylinder 18 from the collection cylinder 17. At this time, the filter cylinder 18 drives the positioning ring 19 to disengage from the collection cylinder 17, thus completing the disassembly of the collection cylinder 17 and the filter cylinder 18. Then, the operator rotates the limit button 703, and then the limit button 703 moves relative to the sleeve 702 and disengages from the limit bridge 12. Next, the operator rotates the limit arm 701 to... The limiting arm 701 disengages from the clamp 6, and simultaneously the limiting arm 701 moves the limiting button 703 away from the limiting bridge 12. Then, the operator moves the cover plate 8 upward, causing the cover plate 8 and the sealing gasket 9 to disengage from the collection box 5. Next, the operator moves the collection box 5, causing the collection box 5 to disengage from the base plate 4, thus completing the disassembly of the collection box 5. The operator then pours out the waste from the collection box 5, the collection cylinder 17, and the filter cylinder 18, and cleans the disassembled parts. Therefore, the device is easy to disassemble, which facilitates thorough cleaning of the device and prevents the growth of bacteria inside the device, thereby improving the hygiene of the device.
[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
