Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an adjustable constant negative pressure drainage device. Background Technology

[0002] After surgery, if a patient has fluid accumulation in their body, such as ascites or pleural effusion, doctors need to use negative pressure to drain the fluid. If fluid accumulates in the patient's body or at the postoperative wound site, and this fluid cannot be drained in time, it will increase the patient's pain, hinder wound healing, and easily lead to infection. In such cases, external negative pressure drainage bags or drainage canisters are usually used to generate negative pressure, allowing the fluid to drain into a negative pressure container.

[0003] The prior art discloses a continuous suction-type negative pressure drainage tank device with constant negative pressure maintenance, application number CN202121280300.1. The device includes a tank body, a drainage pipe connector on the upper surface of the tank body, a drainage pipe connected to the connector, a liquid outlet mechanism for emptying the liquid accumulated in the tank on one side of the connector, a negative pressure marking mechanism for viewing the pressure inside the tank on one side of the outlet mechanism, and a negative pressure mechanism for suctioning negative pressure from the tank on one side of the marking mechanism. This invention facilitates observation of the negative pressure inside the tank through the negative pressure marking mechanism. Through the suction of the negative pressure suction rod of the negative pressure mechanism, continuous negative pressure suction can be achieved, maintaining a strong negative pressure state at all times. The structure is simple, operation is convenient, and the operation difficulty is low. The tank body and the negative pressure fixing inner shell are integrated and fixed with a negative pressure suction cylinder similar to a syringe, facilitating disassembly and assembly. The cost is low, the structure is simple, and the effect is stable.

[0004] The aforementioned container is placed on the ground so that it can draw fluid from the patient's pleural cavity. However, when the doctor performs the procedure, there may be a collision between the doctor and the container, which can cause the container to move and be easily damaged. It also requires a lot of time to reposition the container. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Please see Figure 1-5 The present invention provides the following technical solution:

[0025] An adjustable constant negative pressure drainage device includes a support device 1 and a drainage tank 3. An extraction pipe 4 is installed at the upper end of the drainage tank 3. An air pump body 2 is installed on the left side surface of the support device 1. The drainage tank 3 is installed inside the support device 1.

[0026] The support device 1 includes a fixed base 11, a metal frame 12, and a clamping assembly 13. The clamping assembly 13 is bolted to the upper end of the metal frame 12, and the fixed base 11 is fixedly connected to the bottom surface of the metal frame 12.

[0027] The clamping assembly 13 includes a clamping plate 131, a connecting rod 132, a limiting cover plate 133, a hexagonal bolt 134, a coil spring 135, and a threaded rod 136. The hexagonal bolt 134 is threadedly connected to the surface of the connecting rod 132 and to the upper end of the metal frame 12. The connecting rod 132 is slidably connected to the upper end of the metal frame 12. The hexagonal bolt 134 rotates at the upper end of the metal frame 12. The hexagonal bolt 134 can thread the metal frame 12 and the connecting rod 132 together. The clamping plate 131 is fixed, and its position is determined. The connecting rod 132 is inserted into the inner wall surface of the clamping plate 131. The drainage tank 3 is movably connected to the top surface of the fixed base 11 and the inner wall surface of the clamping plate 131. The clamping plate 131 and the fixed base 11 can determine the position of the drainage tank 3, facilitating the disassembly and replacement of the drainage tank 3. There are two clamping plates 131, which are arranged front and back. The clamping plates 131 can hold... The drainage tank 3 is clamped and fixed to prevent it from shaking. A limiting cover 133 is inserted into the upper end of the clamping plate 131 and slidably connected to the threaded end surface of the threaded rod 136. The limiting cover 133 is also movably connected to the inward end of the connecting rod 132. The limiting cover 133 slides on the threaded end surface of the threaded rod 136, allowing it to insert into the inner surface of the clamping plate 131. This determines the position of the connecting rod 132, facilitating the clamping of the drainage tank 131. 131 is disassembled and replaced. The connecting rod 132 is fixedly connected to the inner side surface of the helical spring 135. The helical spring 135 is fixedly connected to the upper end of the metal frame 12. There are two helical springs 135, which are distributed front and back. The helical springs 135 can rebound and push the clamping plate 131 to slide inside the metal frame 12, which can clamp and fix the drainage tank 3. The threaded rod 136 is fixedly connected to the outer end of the connecting rod 132.

[0028] In use, push the connecting rod 132 into the upper end of the metal frame 12, so that the connecting rod 132 slides on the upper end of the metal frame 12, thereby adjusting the position of the connecting rod 132.

[0029] The coil spring 135 is pushed onto the surface of the connecting rod 132, so that the upper end of the coil spring 135 and the metal frame 12 are movably connected, thereby determining the position of the coil spring 135.

[0030] Push the clamping plate 131 upward, and the clamping plate 131 slides on the inner end surface of the connecting rod 132, so that the connector of the connecting rod 132 clamps the inner wall surface of the clamping plate 131, and initially connects the connecting rod 132 and the clamping plate 131.

[0031] When the limiting cover plate 133 moves upward, the limiting cover plate 133 and the outer surface of the coil spring 135 are movably connected, thereby enabling the position of the coil spring 135 to be initially determined.

[0032] Push the limiting cover plate 133 downward and insert it into the interior of the clamping plate 131, so that the limiting cover plate 133 slides on the inner wall surface of the clamping plate 131. At the same time, the limiting cover plate 133 slides on the threaded end surface of the threaded rod 136, which can fix the clamping plate 131, the connecting rod 132 and the limiting cover plate 133 by threads.

[0033] Push the drainage tank 3 downward, and the drainage tank 3 slides on the inner wall surface of the clamping plate 131, so that the bottom surface of the drainage tank 3 is connected to the top surface of the fixed base 11.

[0034] When the clamping plate 131 slides inside the metal frame 12, the clamping plate 131 can push the connecting rod 132 to slide on the inner wall surface of the metal frame 12, and then the helical spring 135 can be compressed between the clamping plate 131 and the metal frame 12.

[0035] Rotating the hex bolt 134 can thread-fix the metal frame 12 and the connecting rod 132, which can determine the position of the clamping plate 131, thereby clamping and fixing the drainage tank 3, making it convenient to disassemble and replace the drainage tank 3, and protecting the safety of the drainage tank 3.
