Metering type infusion device capable of adjusting infusion amount through positive pressure and negative pressure

Abstract

The invention belongs to the field of medical infusion devices, particularly relates to a metering type infusion device capable of adjusting an infusion amount through a positive pressure and a negative pressure, and aims to solve the problems that the conventional infusion device is complicated in dispensing process operation and easily polluted, and the amount of infusion liquid is difficult to control. The metering type infusion device capable of adjusting the infusion amount through the positive pressure and the negative pressure provided by the invention consists of a pressurizing device, a control switch, a positive pressure purifier, a negative pressure purifier, a large infusion bottle, a small infusion bottle, a metering device, an air inlet needle, a liquid outlet needle, a liquid inlet needle and an air outlet needle; the four needles are fixed by directly inserting rubber caps at the bottle openings or fixed by utilizing needle fixing devices. A manual controller is arranged on each needle fixing device. Automatic control of the device can be realized, and manual control of the device can also be realized. The infusion device capable of adjusting the infusion amount through the positive pressure and the negative pressure disclosed by the invention is used in the field of the medical infusion devices.

Description

technical field [0001] The invention belongs to the field of medical infusion devices, and in particular relates to an infusion device for adjusting the amount of infusion by using positive and negative pressures. Background technique [0002] In 2005, China's medical device market has become the third largest market in the world after the United States and Japan. The annual sales of medical devices reached 32.5 billion yuan, and the industry's annual growth rate was about 14%-15%. [0003] In the treatment of diseases such as diarrhea and digestive tract infections, the fastest and most convenient treatment method is infusion. The traditional dispensing process usually uses a syringe to extract part of the liquid in the bottle, and then uses the syringe to inject liquid medicine or solid medicine into the bottle to complete the dispensing process. This process has the problems of complex operation, easy contamination and difficulty in accurately controlling the volume of i...
