Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to an anti-dumping infusion pole. Background Art

[0002] An infusion pole is a medical device frequently used in various departments of a hospital. The infusion pole comprises a base for support and a pole body mounted on the base for mounting an infusion bag and other medical devices.

[0003] To improve support stability and transport ease, existing infusion poles employ a method that expands the base and installs rollers underneath the base. However, this expansion of the base's support reduces the ease of transport, while the installation of rollers further weakens the pole's support stability. This creates a conflict between support stability and transport ease, making it difficult to achieve both.

[0004] Patients with certain medical conditions, in particular, require constant access to medical equipment such as nutritional infusions and ventilators to maintain basic vital signs. The nutritional infusion bags and other equipment mounted on the top of the infusion pole can weigh five kilograms or more. In this case, expanding the support range of the infusion pole base would sacrifice transport convenience, potentially hindering timely patient treatment. A smaller support range would cause the pole to tip over at the slightest touch when stationary, further weakening its support stability to the point of precariousness.

[0005] Therefore, in view of the above-mentioned defects of the existing infusion pole, the present utility model patent discloses an anti-dumping infusion pole. Utility Model Content

[0045] The rest of this embodiment is the same as that of embodiment 1 or 2, so it will not be described again. Example

[0046] This embodiment is further optimized based on embodiment 3. Figures 1 to 4 As shown, it also includes a tray slide 51, a flip tray 52 and a pull rod 53. The tray slide 51 is fixedly installed on the driving rod 5 along the length direction of the driving rod 5.

[0055] In a specific embodiment, the supporting rod 542 further serves to limit the rotation of the flip tray 52 and also increases the load-bearing weight limit of the flip tray 52. ​​During long-term use, it can protect the connection between the flip tray 52, the pull rod 53, the slider 511 and the tray slide rail 51 from being damaged due to long-term excessive force, thereby extending the service life and improving the reliability of use.

[0056] The rest of this embodiment is the same as that of embodiment 6, so it will not be described again. Example
