Description

Technical Field

[0001] This utility model relates to the field of infusion stand technology, specifically a barrier-free mobile automatic bottle-changing infusion stand. Background Technology

[0002] Infusion stands are mainly used in medical environments and are essential medical equipment in medical facilities. When in use, the patient sits or lies down next to the infusion stand, the infusion bottle is suspended on the infusion stand, and through the infusion tube and needle, the medication is injected into the patient's vein using the principle of atmospheric pressure to achieve the purpose of treatment.

[0003] Currently, there are two common types of IV stands on the market: one is a hanging type, whose base is fixed to the ceiling and moves using guide rails; the other is a standing type, whose base is fixed to the ground and is not easy to move. Existing IV stands are inconvenient to move. When the patient needs to move, especially when urgently needing to use the restroom, a caregiver must hold the IV bag high and accompany them, making these stands very inconvenient to use. In clinical practice, a patient often needs to receive multiple IV drips consecutively. During this process, nurses need to help change the IV bags multiple times, and patients or caregivers need to constantly monitor the remaining fluid level. Often, patients become tired and fall asleep, failing to notice when the IV has finished, leading to backflow of blood. Utility Model Content

The IV needle is fixed to the IV needle holder 41, and the hanging height of the infusion bottle is adjusted using the telescopic device 2.

[0047] The liquid level sensor 8 is used to detect the liquid level. When the liquid level drops to a certain height and the infusion bottle needs to be replaced, the controller receives a signal and controls the servo motor 43 of the insertion and removal device 4 to rotate. The insertion and removal device 4 drives the infusion needle downward to pull it out of the empty infusion bottle. The rotating device 6 drives the infusion bottle fixing device 5 to rotate, moving the empty infusion bottle away and rotating the infusion bottle containing the liquid to above the infusion needle. The insertion and removal device 4 drives the infusion needle upward to insert it into the infusion bottle containing the liquid, realizing automatic bottle replacement and continuing the infusion, thereby reducing the workload of medical staff.

[0048] When the IV stand needs to be moved, the controller activates the travel motor 17, which in turn drives the central gear 15, tripod 13, and small wheels 14 to rotate synchronously, thus moving the IV stand without manual pushing, greatly reducing the user's physical burden. The casters 12 are highly flexible and can rotate freely in all directions. The triangular wheel assembly can easily handle different terrains such as stairs and ramps, exhibiting strong terrain adaptability and good stability.

[0049] This utility model is easy to move and can overcome obstacles. It can automatically replace IV drips, reducing the workload of medical staff.
