Description

Technical Field

[0001] The utility model belongs to the field of medical auxiliary products, and in particular relates to an anti-dropping device for an infusion set. Background Art

[0002] During intravenous infusion therapy, patients with unclear consciousness or excessive activity are prone to loosening of the connection between the infusion set and the infusion bag. This situation not only causes pollution to the infusion environment, but also requires medical staff to perform a series of tedious operations such as replacing the infusion set, re-venting and connecting the infusion device to continue treatment. This not only increases the workload of medical staff, but also increases the discomfort and treatment risks of patients.

[0003] In response to this problem, some anti-dropout mechanisms have been proposed. For example, in the Chinese invention patent application with publication number CN113262357A, a device for preventing an infusion set from being detached from an infusion bag is disclosed. The device includes an infusion set connection groove, a threaded connecting rod and an embedded plate, as well as components such as a sleeve plate, a movable sleeve ring and a limit rod. Although this design can ensure a stable connection between the infusion set and the infusion bag and prevent accidental dropout, its structure is complex, the operation is inconvenient, and the production cost is high, which limits its application in a wide range of medical environments. Utility Model Content

[0004] In order to overcome the problems of complex structure and other problems existing in the existing anti-dropout mechanism, the utility model provides an infusion set anti-dropout device, which enables the supporting funnel to provide an upward supporting force for the drip bucket of the infusion set through the upward pulling force of the anti-dropout rope, thereby effectively preventing the infusion set from falling off, and has a simple structure, is easy to use and has a low manufacturing cost.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] An infusion set anti-dropout device comprises a supporting funnel, wherein the supporting funnel is hollow inside and at least the top is open; an opening is provided on the side wall of the supporting funnel, which is arranged from top to bottom, so that the lower section of the pipeline of the infusion set dripping funnel can be embedded into the supporting funnel through the opening; the top opening size of the supporting funnel is larger than the diameter of the infusion set dripping funnel bottle body, and the bottom size is smaller than the diameter of the infusion set dripping funnel bottle body, the infusion set dripping funnel extends into the supporting funnel from the top opening of the supporting funnel, and the bottom of the infusion set dripping funnel abuts against the bottom of the supporting funnel; an anti-dropout rope is fixedly connected to the side wall of the supporting funnel, and the top end of the anti-dropout rope is hung on the hook of the infusion stand, so as to provide an upward pulling force for the supporting funnel.

[0007] Based on the above scheme, after the supporting funnel is embedded in the lower section of the drip bucket of the infusion set, the anti-slip rope is lifted up so that the drip bucket of the infusion set extends from the top opening of the supporting funnel into the interior of the supporting funnel until the bottom of the drip bucket of the infusion set abuts against the bottom of the supporting funnel, thereby providing an upward supporting force for the drip bucket of the infusion set, effectively supporting and fixing the drip bucket of the infusion set to prevent it from falling off due to shaking or touching during use. The full-length opening on the side wall of the supporting funnel allows the lower section of the drip bucket of the infusion set to be easily embedded in the interior of the supporting funnel, and the drip bucket can be fixed without complicated operations. At the same time, the top of the anti-slip rope is directly hung on the hook of the infusion stand, making the installation, disassembly and use of the entire anti-slip device very simple and quick, thereby improving the versatility and practicality of the device.

[0008] Furthermore, the supporting funnel includes an integrally connected cup body and a transition section, the cup body is a conical cylindrical structure with a top diameter larger than a bottom diameter and a through-hole in the middle, the transition section is a cylindrical structure with a through-hole in the middle, and the transition section is connected to the bottom of the cup body.

[0009] The tapered cylindrical structure of the supporting funnel and the cylindrical transition section design at the bottom can enhance the supporting stability of the infusion set drip bucket inside the supporting funnel.

[0010] Furthermore, the anti-drop rope is provided with a live fastener for adjusting the required effective length of the anti-drop rope.

[0011] The use of the live fastener allows medical personnel to adjust the effective length of the anti-drop rope according to actual conditions to adapt to the use of different infusion sets and liquid bags / bottles.

[0012] Furthermore, the supporting funnel is made of plastic, and the material cost is low.

[0013] In summary, the beneficial effects of the present invention include:

[0014] The infusion set anti-dropout device has a simple structure, low manufacturing cost, convenient and quick use, and is economical and practical. During use, the length of the anti-dropout rope can be flexibly adjusted according to the size of the infusion bag, and the upward pulling force of the anti-dropout rope enables the supporting funnel to provide an upward supporting force for the drip bucket of the infusion set, effectively preventing the infusion set from falling off during use, reducing the workload of nurses, and reducing unnecessary expenses for patients, and is suitable for large-scale promotion and application.
