Description

Technical Field

[0001] This utility model relates to the field of negative pressure drainage technology, and in particular to a split-type negative pressure drainage rotary valve that is easy to operate with one hand. Background Technology

[0002] In the clinical medical field, negative pressure drainage technology is widely used in scenarios such as wound drainage and body cavity effusion drainage. With the help of negative pressure, the drainage fluid can be efficiently collected into a container.

[0003] However, the rotary valves of existing negative pressure drainage devices have certain shortcomings: most existing rotary valves are one-piece structures or have complex operating logic, requiring both hands to switch between "opening / closing". When medical staff or patients need to operate with one hand (such as using the other hand to perform fixation, dressing changes, etc.), the operation is extremely inconvenient and can easily lead to drainage interruption or negative pressure leakage due to improper operation. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art and to propose a split-type negative pressure drainage rotary valve that is easy to operate with one hand.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A split-type negative pressure drainage rotary valve that is easy to operate with one hand includes an upper cover and a lower cover, which are rotatably connected. A drainage tube is fixedly connected to the upper cover, and a negative pressure tube is fixedly connected to the lower cover. A connecting block is fixedly connected to the upper cover, and a connecting hole is provided on the connecting block, which is connected to the drainage pipe; The connecting pipe is fixedly connected to the lower cover. A partition is fixedly connected to the lower cover, and the partition is provided with air guide holes and liquid guide holes; The liquid guiding hole is located directly above the connecting pipe; The upper cover body drives the connecting block to rotate, and the connecting block synchronously drives the connecting hole to rotate directly above the liquid guiding hole.

[0006] Preferably, a first threaded tooth is fixedly connected to the upper cover, and a threaded groove is provided on the top of the lower cover, wherein the first threaded tooth and the threaded groove are threadedly matched.

[0007] Furthermore, a second threaded tooth is fixedly connected to the lower cover.

[0008] Preferably, a mounting rod is fixedly connected to the lower cover, and a mounting hole matching the mounting rod is provided on the connecting block.

[0009] Compared with the prior art, this utility model provides a split-type negative pressure drainage rotary valve that is easy to operate with one hand, and has the following beneficial effects: All parts of the device not described herein are the same as or can be implemented using existing technologies. This utility model, through the rotational cooperation of the upper and lower covers, allows the switching of the upper cover's "counterclockwise opening" and "clockwise closing" operations to be completed with just one hand, without the need for two-handed coordination. This effectively improves operational convenience, is suitable for multi-tasking scenarios in clinical nursing, and effectively improves work efficiency. Attached Figure Description

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0013] Reference Figures 1-5 A split-type negative pressure drainage rotary valve that is easy to operate with one hand includes an upper cover 1 and a lower cover 2, which are rotatably connected. A drainage tube 101 is fixedly connected to the upper cover 1, and a negative pressure tube 201 is fixedly connected to the lower cover 2; The connecting block 4 is fixedly connected to the upper cover 1, and the connecting block 4 has a connecting hole 401, which is connected to the drainage pipe 101. The connecting pipe 205 is fixedly connected to the lower cover 2; The partition 3 is fixedly connected to the lower cover 2, and the partition 3 is provided with an air guide hole 301 and a liquid guide hole 302. The liquid guide hole 302 is located directly above the connecting pipe 205; The upper cover 1 drives the connecting block 4 to rotate, and the connecting block 4 synchronously drives the connecting hole 401 to rotate directly above the liquid guiding hole 302.

[0014] The upper cover 1 is fixedly connected with a first threaded tooth 102, and the lower cover 2 has a threaded groove 202 on its top. The first threaded tooth 102 and the threaded groove 202 are threadedly matched.

[0015] A second screw 203 is fixedly connected to the lower cover 2.

[0016] Reference Figures 1-2 It should be noted that when using this device, the negative pressure tube 201 should be connected to the negative pressure machine; the drainage tube 101 should be connected to the drainage conduit; and the assembled lower cover 2 should be screwed onto the collection bottle.

[0017] Reference Figures 1-5 In specific operation, the staff rotates the upper cover 1 counterclockwise with one hand. At this time, the connecting block 4 will rotate synchronously. After the upper cover 1 rotates to a certain angle, the connecting hole 401 on the connecting block 4 will rotate to the position directly above the liquid guiding hole 302 on the partition 3. At this time, the air guiding hole 301 will be exposed. Then, by drawing negative pressure through the negative pressure machine, the drainage fluid can be drawn into the collection bottle through the drainage tube 101. At this time, the drainage fluid will be transported into the collection bottle through the drainage tube 101, the liquid guiding hole 302 and the connecting tube 205, thus completing the drainage collection.

[0018] By rotating the upper cover 1 and the lower cover 2 (combining the thread matching of the first threaded tooth 102 on the upper cover 1 and the threaded groove 202 on the top of the lower cover 2, and the guide and limit of the mounting rod 204 on the lower cover 2 and the mounting hole 402 on the connecting block 4), the operation of switching between "counterclockwise opening" and "clockwise closing" of the upper cover 1 can be completed with just one hand, without the need for two-handed coordination, which greatly improves the convenience of operation and is suitable for multi-tasking scenarios in clinical nursing, such as when medical staff operate with one hand, the other hand can simultaneously carry out wound observation, catheter fixation and other tasks.

[0019] Reference Figures 1-5 When closed, the operator can rotate the upper cover 1 clockwise with one hand. At this time, the connecting block 4 will rotate in the opposite direction to reset. After rotating a certain angle, the connecting hole 401 on the connecting block 4 will no longer be connected to the liquid guide hole 302, and the rotated connecting block 4 will cover the air guide hole 301.

[0020] A mounting rod 204 is fixedly connected to the lower cover 2, and a mounting hole 402 matching the mounting rod 204 is provided on the connecting block 4.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
