Benefits of technology

The technical effect of this patented technology reduces the amount of x ray exposure for medical professionals by controlling their injected fluids at different pressures or rates while minimizing any risks associated therewith. This allows them to perform procedures that are easier but still effective than traditional methods like syringe pump techniques. Additionally, it simplifies the procedure and improves working efficacy compared to current systems.

Problems solved by technology

Technological Problem: Current methods involve manual processes such as shaking or sticking up after administering a small amount of fluid called saline solution through one end while another area's body remains unimpaired. These techniques are time-consuming and may lead to complications like bleeding from damaging veins caused by excess liquid introduced at other points along their pathway.

Embodiment 2

[0031] Embodiment 2, on the basis of embodiment 1, the specific implementation structure diagram of this design is as follows Figure 4 shown. The injection panel controller can be a TI ARM Conrtex-A8 high-performance processor AM3354 with a main frequency of 1GHz and a computing capacity of 1600DMIPS; the injection head controller can be a STM32F103ZET6 chip, which has the highest performance RISC core and USB interface , JTAG (download port of the control program), the highest operating frequency is 72MHZ.

[0032] In a specific implementation manner, it is divided into the following types of physical connections.

[0033] 1. The two conduits on the pressure controller are respectively connected to the two air pressure sensors to convert the finger pressure signal into an electrical signal. The electrical signal passes through a 0-100Hz low-pass filter circuit to filter out the complex clutter of the signal, and then After the amplification circuit and access to the acquisit...

Abstract

The invention discloses an automatic angiography injection system. The system comprises a pressure operation unit, a syringe panel, a syringe head unit and a power supply unit, the pressure operationunit is connected with the syringe panel, the syringe panel is also connected to the syringe head unit, and the syringe head unit is connected with the power supply unit. The operation of the system is safe and simple, firstly, the system converts a finger pressure into a real-time injection rate of the angiographic injection system through the pressure operation unit, achieves variable flow rateinjection, reduces the use amount of a contrast agent, and reduces radiation; in addition, the system monitors the injection status in real time through a safety monitoring assembly to ensure safety and reliability during the injection process. Finally, the system uses matching consumables to automatically switch contrast agent injection pipelines and saline flushing pipelines for real-time bloodpressure monitoring, and provides convenience for doctors to operate.
