Driving device of micro injection pump

Abstract

The invention provides a driving device for a micoscale medicine injection pump. A connector sheath used for being connected with an infusion device is arranged on the upper portion of the driving device, a display device and a key device are arranged on the outer surface of the driving device, and a PCA inserting hole, a PCA key and a bubble sensor are arranged at one side of the driving device; an MPU unit is arranged in the driving device, and the MPU unit comprises a host computer MPU unit and a monitoring MPU unit which are mutually connected; the input end of the host computer MPU unit is connected with a detecting unit and a clock circuit, the host computer MPU unit is electrically connected with an LCD display unit and a keyboard unit, and the LCD display unit and the keyboard unit are correspondingly connected with the display device and the key device respectively; the host computer MPU unit is further connected with a watchdog timer circuit; the output end of the host computer MPU unit is connected with a segmentation alarm output unit and a motor switch block. According to the driving device for the micoscale medicine injection pump, through the design of the modules including a double chip structure, the detecting unit and the clock circuit and the like, the alarm function and the data storage function of the micoscale medicine injection pump are improved.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a driving device for a micro-injection pump. Background technique [0002] At present, hospitals rely on micro-injection pumps for drug injection in many cases. The micro-injection pump consists of two parts: the driving device and the infusion device matched with the driving device. The infusion device is for one-time use and cannot be reused, while the driving device can be used repeatedly and can be used normally without any failure or false alarm. . [0003] However, there are still some deficiencies in the injection pump of the prior art, which cannot meet the constantly updated demands of people. For example, the alarm mechanism of the injection pump in the prior art is not perfect enough. When there are too many air bubbles in the injected medicinal liquid, the medicinal liquid is interrupted or the infusion is blocked, the delivery situation of the medicinal liquid cann...

[0003] But the injection pump of prior art also has some weak points, can not satisfy people's constantly updated demand

For example, the alarm mechanism of the injection pump in the prior art is not perfect enough. When there are too many air bubbles in the injected medicinal liquid, the medicinal liquid is interrupted or the infusion is blocked, the delivery situation of the medicinal liquid cannot be fed back accurately and timely, which may cause serious harm to the patient. cause invisible harm; in addition, the injection pump of the prior art lacks the function of data storage, and cannot provide accurate and effective treatment data when it is necessary to inquire about the treatment process and treatment records, especially when dealing with medical disputes, it can It is very important to query the injection volume at that time, so long-term or even permanent storage function is required
