Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a multifunctional armrest. Background Art

[0002] In the medical field, patients often need to maintain their arm posture for a long time due to the need for infusion. Maintaining the same posture for a long time may cause arm fatigue and discomfort, and even affect the treatment effect and patient recovery. Medical armrests, as auxiliary medical equipment, are essential for providing comfortable arm support and reducing fatigue.

[0003] Traditional patient transport carts are not equipped with arm supports, which brings inconvenience to patients during infusion and injection before surgery. Existing medical arm rests are usually simple in design and have relatively single functions. They only provide basic support, are not convenient to use, and are difficult to adjust the support angle. Patients keep their arms straight for a long time, which can easily cause muscle fatigue or injury. For this reason, we propose a multifunctional arm rest. Utility Model Content
