Abstract
Description
Technical Field
[0001] This utility model belongs to the field of blood collection equipment technology, and specifically relates to a blood collection device for hematology departments. Background Technology
[0002] In hospital phlebology and laboratory departments, it is often necessary to draw blood from patients for testing. Blood testing is the most common method used in medicine to check whether a patient's body fluids are normal. It is a revolution in clinical diagnostics. A blood collection device is an effective medical instrument for drawing blood from patients.
[0003] Currently, Chinese utility model patent CN206167238U discloses a medical blood collection device. This device fixes the blood collection device to the hospital bed using a connecting clip. However, while the blood collection device is initially lightweight, its weight increases after multiple blood collection tubes are placed in it. The connecting clip alone is insufficient to effectively fix the blood collection device, making it prone to falling off. Furthermore, the device lacks a cushioning function, which makes it difficult to cushion the blood collection tubes when the blood collection device is bumped or accidentally dropped, potentially leading to the breakage of the blood collection tubes. Utility Model Content
