Description

Technical Field

[0001] The utility model relates to the technical field of infusion pumps, in particular to a venous infusion pump which is convenient for patients to carry. Background Art

[0002] Intravenous infusion is a common and important treatment for diseases. Traditionally, intravenous infusion relies primarily on gravity, with the infusion rate controlled by adjusting a switch on the infusion tube. This method has numerous drawbacks, including poor controllability. With the continuous advancement of medical technology, intravenous infusion pumps have gradually gained application. To facilitate their use, most intravenous infusion pumps on the market are portable.

[0003] For example, the Chinese patent with patent number CN202020098137.6 discloses a portable intravenous infusion pump, comprising a housing, a limiting rod fixedly connected between the top and bottom of the inner cavity of the housing, a fixed frame fixedly connected to the top and bottom of the inner cavity of the housing, a damper and a first spring fixedly connected to the bottom of the inner cavity of the fixed frame, and the first spring is sleeved on the surface of the damper. This portable intravenous infusion pump achieves the purpose of good buffering effect through the cooperation of the housing, the limiting rod, the fixed frame, the damper, the first spring, the support plate, the slider, the chute, the push rod, the fixed block, the second spring, the connecting plate, the linkage block and the intravenous infusion pump body, but cannot effectively protect the portable intravenous infusion pump, which easily causes the portable intravenous infusion pump to be damaged during movement, reduces the user's experience of the portable intravenous infusion pump, cannot meet the needs of the current market, and solves the problem that the previous portable intravenous infusion pump did not have a buffer structure.

[0004] The portable intravenous infusion pump provided by the aforementioned patent primarily features a protective mechanism on its exterior to protect the pump from damage due to impact during movement. In practice, when using the intravenous infusion pump, staff typically secure it to an infusion support rod, hang a medicine bottle or bag on the top of the rod, and then connect the infusion tube to the intravenous infusion pump. While this makes the intravenous infusion pump stable to use, if the patient wants to go to the restroom during the infusion, the infusion support rod is fixed and cannot be moved, or is inconvenient to move. This requires a caregiver to disassemble the intravenous infusion pump, lift the medicine bottle and the intravenous infusion pump, and follow the patient to the restroom. This entire operation is extremely cumbersome, and it is very troublesome for the caregiver to lift both the medicine bottle and the intravenous infusion pump. Therefore, there is an urgent need for an infusion pump that can easily carry the medicine bottle, allowing the caregiver to quickly and easily move the infusion pump and medicine bottle when the patient needs to go to the restroom.
