It is easy to use, occupies little space, and can be moved flexibly. It is commonly used in operating rooms, ICUs, emergency wards and other departments.
[0003] The medical pendant has the functions of medical gas input, negative pressure suction, and waste gas discharge. The negative pressure gas pipeline of the medical pendant can absorb a large amount of blood, secretions, sputum, pleural effusion and other substances, and these substances will adhere to the inner wall of the negative pressure gas pipeline. This will cause blockage of the negative pressure gas pipeline in the long term, affecting clinical use.
[0004] Therefore, there is an urgent need in the art for a medical pendant gas pipeline anti-blocking device to solve the above-mentioned problems. Utility Model Content
[0005] The purpose of the utility model is to provide a medical pendant gas pipeline anti-clogging device to solve the problems existing in the above-mentioned prior art. The attachments on the inner wall of the negative pressure gas pipeline are scraped off by spiral blades, and the waste liquid and waste gas are driven to be discharged through the spiral blade structure, thereby preventing the negative pressure gas pipeline from being blocked.
[0006] To achieve the above purpose, the utility model provides the following solutions:
[0007] The utility model provides a medical pendant gas pipeline anti-blocking device, comprising a rotating shaft, a spiral blade and two bearings, wherein the spiral blade is fixed to the outer side wall of the rotating shaft, the inner rings of the two bearings are respectively fixed to the two ends of the rotating shaft, and the outer rings of the two bearings are fixed to the inner wall of the negative pressure gas pipeline in the medical pendant.
[0008] Preferably, the rotating shaft and the spiral blades are an integrated structure.
[0009] Preferably, the rotating shaft and the spiral blades are made of plastic.
[0010] Preferably, the rotating shaft and the spiral blades are made of polypropylene.
[0011] Preferably, the outer surfaces of the rotating shaft and the spiral blades are provided with an anti-stick coating.
[0012] Preferably, the anti-stick coating is made of polytetrafluoroethylene.
[0013] Compared with the prior art, the utility model has achieved the following technical effects:
[0014] The utility model installs a rotating shaft, a spiral blade and a bearing into a negative pressure gas pipeline. When the negative pressure gas pipeline is started, the rotating shaft and the spiral blade rotate under the action of the negative pressure gas, and the spiral blade is used to scrape off the attachments on the inner wall of the negative pressure gas pipeline, and the waste liquid and waste gas are driven to be discharged through the spiral blade structure, thereby preventing the problem of blockage of the negative pressure gas pipeline.
[0015] Furthermore, the maintenance costs due to blockage problems are reduced;
[0016] Furthermore, the device is integrated into the negative pressure gas pipeline and does not require an additional power source, so the manufacturing cost is low;
[0017] Furthermore, the overall design is simple and uses less materials, which can further save costs. BRIEF DESCRIPTION OF THE DRAWINGS
[0018] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings required for use in the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] The purpose of the utility model is to provide a medical pendant gas pipeline anti-clogging device to solve the problems existing in the above-mentioned prior art. The attachments on the inner wall of the negative pressure gas pipeline are scraped off by spiral blades, and the waste liquid and waste gas are driven to be discharged through the spiral blade structure, thereby preventing the negative pressure gas pipeline from being blocked.
[0024] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0025] like Figure 1-Figure 2 As shown, the utility model provides a medical pendant gas pipeline anti-blocking device, comprising a rotating shaft 1, a spiral blade 2 and two bearings 3. The spiral blade 2 is fixed to the outer wall of the rotating shaft 1, the inner rings of the two bearings 3 are respectively fixed to the two ends of the rotating shaft 1, and the outer rings of the two bearings 3 are fixed to the inner wall of the negative pressure gas pipeline in the medical pendant. Since the damping of the bearing 3 is small, the rotating shaft 1 and the spiral blade 2 can be rotatably connected to the inside of the negative pressure gas pipeline in the medical pendant.
[0026] When the negative pressure gas pipeline in the medical pendant is started, the external gas flows into the interior under the action of negative pressure, and at the same time, it will drive the rotating shaft 1 and the spiral blade 2 to rotate, and the spiral blade 2 will scrape off the attachments on the inner wall of the negative pressure gas pipeline, and drive the waste liquid and waste gas to be discharged through the spiral blade 2 structure, thereby preventing the problem of blockage of the negative pressure gas pipeline.
[0027] In this embodiment, the rotating shaft 1 and the spiral blades 2 are an integrated structure and are integrally formed during the manufacturing process, which not only reduces the manufacturing cost and allows for bulk sales, but also reduces transportation costs.
[0028] In this embodiment, the rotating shaft 1 and the spiral blades 2 are made of plastic material. Plastic material is generally light in weight and has low manufacturing cost.
[0029] In this embodiment, the material used for the rotating shaft 1 and the spiral blades 2 is polypropylene (PP) among plastic materials, which is not only light in weight but also has certain anti-corrosion performance, thereby being able to increase its service life.
[0030] In this embodiment, the outer surfaces of the rotating shaft 1 and the spiral blades 2 are provided with an anti-stick coating. The purpose of providing the anti-stick coating is to prevent waste liquid and waste gas from adhering to the surfaces of the rotating shaft 1 and the spiral blades 2, thereby reducing the clogging effect.
[0031] In this embodiment, the specific material of the anti-stick coating includes but is not limited to polytetrafluoroethylene (PTFE). Those skilled in the art may also use other materials in the prior art as long as they can prevent waste liquid, waste gas and other waste from sticking to the surface of the equipment.

The above examples are only used to help understand the method and core idea of the present invention. At the same time, for those skilled in the art, according to the idea of the present invention, there will be changes in the specific implementation and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
