Embodiment 1

[0030] Such as figure 1 , figure 2As shown, a high-pressure injection system includes an injection device arranged in the filming room, the injection device is used for injecting the patient, and the injection device is electrically connected with the main controller and the secondary controller respectively; The controller, the secondary controller and the terminal are electrically connected in sequence and connected in series. The terminal is used to receive and display the data of the primary and secondary controllers; the primary and secondary controllers are used to control the components in the injection device and perform corresponding operations. The long-distance communication between the controller and the terminal is realized through wired 485 or wireless 433 . The primary and secondary controllers are both integrated chips, and the terminal is electrically connected to the display. The data received by the two controllers is displayed on the display at the same t...

Embodiment 2

[0036] Basically the same as embodiment 1, for the sake of safety and sanitation, the infusion tube in the peristaltic pump 6 needs to be replaced from time to time, in order to take into account the convenience of changing the infusion tube in the peristaltic pump 6, in this implementation, a side of the infusion tube is provided for Pull the tube device of the infusion tube. Because the infusion tube cooperates with the rollers on the peristaltic pump 6 during liquid delivery, it is inconvenient to take the infusion tube directly from the rollers when replacing the infusion tube. The infusion tube contacted by the roller is toggled to change the flow direction of the infusion tube so as to change the relative positional relationship between the infusion tube and the roller, and finally realize the replacement of the infusion tube. Specifically, in this implementation, the tube pulling device includes a motor, the motor is electrically connected to the main controller, the mo...

Embodiment 3

[0038] Basically the same as embodiment 2, in order to further ensure the safety of the whole system, in this implementation, the bubble detection mechanism includes two, one is arranged on the output pipeline of the peristaltic pump 6, that is, the outlet end of the infusion tube in the peristaltic pump 6, The air bubble detection mechanism is electrically connected with the secondary controller; the other is arranged on the pipeline connected with the injection needle, and the air bubble detection mechanism is electrically connected with the main controller. It is considered that the air bubble detection mechanism is electrically connected with the two controllers respectively. The liquid entering the injection needle is the last line of defense. The risk level is high. There are air bubbles in the pipeline, which may cause blood vessel embolism or even death of the patient. Therefore, dual controllers are required for monitoring to achieve redundant dual control. It is more ...

Abstract

The invention discloses a high-pressure injection system and method, and belongs to the field of medical instruments. Aiming at the problems of low injection efficiency and potential safety hazards in the prior art, the invention provides a high-pressure injection system, which comprises an injection device arranged in a radiography room and a terminal arranged in an operation room, and the injection device is electrically connected with a primary controller and a secondary controller respectively; The injection device comprises a liquid bottle, and liquid in the liquid bottle is conveyed into the injection needle through a peristaltic pump; the peristaltic pump is connected with the driving mechanism; a pressure detection mechanism and a bubble detection mechanism are arranged on a pipeline through which the liquid is conveyed into the injection needle from the liquid bottle; the primary controller and the secondary controller are electrically connected with the driving mechanism, the pressure detection mechanism and the bubble detection mechanism. Liquid is output through the peristaltic pump, pollution is avoided, and stability and precision are high; secondly, the safety mechanism dual control is carried out by adopting a dual-controller mode, so that the safety and the effectiveness of the injection system are ensured. According to the high-pressure injection method, the working efficiency and accuracy are greatly improved, and the safety performance is high.

Description

technical field [0001] The invention belongs to the field of medical equipment, and more specifically relates to a high-pressure injection system and method. Background technique [0002] In many medical diagnosis and treatment processes, doctors or other personnel inject contrast agents into patients with computerized tomography (CT), digital subtraction angiography (DSA), and magnetic resonance system (MR) imaging to assist doctors in diagnosis, usually using angiography The high-pressure injection executing device performs drug injection. At present, angiographic high-pressure injection devices usually use manual push of contrast agent, the contrast agent reaches the detection position through veins or arteries, and obtains images of desired tissue parts by absorbing X-rays or changing the signal intensity of tissues in the body under magnetic resonance. However, for manually aspirating contrast medium or normal saline, and then manually injecting by the operator, the fl...
