Embodiment Construction

[0027] see figure 1 , a self-controlled medical perfusion pump and its control method according to the present invention, comprising a pump execution module 30 , a function module 10 and a control module 20 . Wherein, the execution module 30 realizes the water injection work through the rotation of the motor, including the servo motor 31 and the transmission unit 32 , and the servo motor can be replaced by a motor and a motor drive control circuit.

[0028] The control module 20 is used to control the work of the function module 10 and the execution module 30, including an I / O unit 21, a micro-processing chip 22 and a storage unit 23, which communicate through a data bus and an address bus. Microprocessing chip 22 is a single-chip microcomputer commonly used at present. The storage unit 23 includes erasable or permanent memory commonly used at present, and is mainly used to store key technical parameters and programs. The I / O unit 21 is an input and output interface circuit ...

Abstract

The invention provides a self-controlled medical charging pump and control method, wherein the charging pump method comprises an execution module, a function module used for inputting information and receiving the feedback signal and a control module used for controlling the operation of the function module and the execution module; the control module comprises a I / O unit, a microprocessing chip and a memory unit; the function module comprises an input unit and a signal I / O unit. The control method comprises steps that: inputting the user instruction, selecting the corresponding operating mode according to the input user instruction and executing related actions. The medical charging pump can work at stand-along mode or linkage working mode, wherein the linkage working mode is controlled by surgical equipment which performs surgery, timely controls the open and close of the water flow according to the status of the surgical equipment and realizes effective control of the water flow in operation. The medical charging pump has the advantages that water intoxication complication due to sustainable flush or unnecessary body temperature decrease due to excess washing water consumption or excess flush is decreased.

Description

technical field [0001] The invention relates to a medical perfusion pump, in particular to an automatic control medical perfusion pump and a control method thereof. Background technique [0002] With the development of medical technology, minimally invasive surgery is more and more widely used in clinical operations. During the minimally invasive surgery, local high temperature or appendages such as smoke will be generated, as well as excised tissues, flushing bleeding, etc., all need to be flushed with water. Based on this, Gemeinhardt and Spinosa etc. invented a medical perfusion pump, see US Patents US2773453 and US3927955 for details. The medical perfusion pump mainly uses the surgical channel established during the operation to flush the water flow to the site where the operation is performed with an appropriate pressure to avoid local high temperature during the operation, and at the same time take away the add-ons such as smoke generated by the operation through the ...
