Abstract

The invention provides a safety transfusion device with an automatic needle withdrawing function. The safety transfusion device comprises a control box, a weighing sensor and a needle withdrawing mechanism. A signal conditioning circuit, an analog-digital conversion circuit, a microcontroller, a wireless communication module and a motor driving circuit are arranged inside the control box; the needle withdrawing mechanism comprises a shell, a driving steering engine, a slider and a stay. The safety transfusion device has the advantages that the driving steering engine can work under the control of the microcontroller via the motor driving circuit when coming of the end of the transfusion quantities is detected by the weighing sensor, the slider can be pulled by the stay and can be dragged to move along a slide rail, a needle can be clamped by an elastic chuck to move along with the slider, accordingly, a syringe needle can be withdrawn out of a human body, a transfusion system can have an automatic needle withdrawing function under unattended conditions, and accidents can be prevented.

Description

technical field [0001] The invention relates to a safety infusion device, in particular to a safety infusion device with the function of automatically pulling out needles. Background technique [0002] With the continuous acceleration of the pace of society, the infusion halls or inpatient departments of large hospitals are often overcrowded, and nurses often cannot pay attention to the infusion situation of all patients in time. Although many hospitals have installed manual calling devices, when nursing staff or patients are negligent (such as accidents are still unavoidable. Contents of the invention [0003] The technical problem to be solved by the invention is that the existing manual calling device is still based on manual care, and accidents inevitably occur. [0004] In order to solve the above-mentioned technical problems, the invention provides a safety infusion device with the function of automatically pulling out needles, which includes a control box, a weighi...
