Micro peristaltic infusion device

Abstract

The invention relates to a micro peristaltic infusion device and a use method. The device is an end face peristaltic infusion pump which comprises a pump base and a pump cover of the end face peristaltic infusion pump, and a locking piece which fixes the pump base relative to the pump cover. A shaft hole inserted into the center of the pump base and a cylindrical pump core which rotates around the centre of the cylinder axially are arranged in a cavity of a cylindrical face of the pump base. The pump core is provided with a motor and a speed variator thereof. The end face peristaltic infusion pump is further provided with a storage device; an integral assembly consisting of a liquid medicine bag, a pump pipe jacket and a connector on the pump pipe. A square groove is arranged on the pump cover and can be placed in the pump pipe jacket in a matched manner. The liquid medicine storage device is internally provided with the liquid medicine bag, and the other end of the pump pipe is provided with a standard connector connected with an external standard infusion assembly. With the adoption of the end face peristaltic pump, the automatic trace injection device is simple in structure and high in control precision. The liquid medicine storage device is used to maintain the pre-pressure of the liquid medicine, and the integral assembly facilitates replacement of the liquid medicine and the pump pipe, so that secondary pollution is effectively avoided.

Description

technical field [0001] The invention belongs to a medical device, in particular to a miniature peristaltic infusion device. Background technique [0002] Insulin pump is an automatic injection device for diabetics to supplement insulin outside the body. It has been proved to be an effective method for treating diabetes for many years. For patients, this miniature portable infusion pump is a very convenient device. It has been popularized in various countries in the world. The main brands are MINIMED in the United States, H-TRON in Switzerland, and DANA in South Korea. The prices are all tens of thousands of yuan, and the daily maintenance costs such as lithium batteries and other prices and quality are also issues that must be paid attention to. Now countries around the world The insulin pumps manufactured all use ultra-micro motors to drive high-precision syringes, and the high price is indeed difficult to popularize and promote. Another major defect of this device is the ...

[0002] Insulin pump is an automatic injection device for diabetics to supplement insulin outside the body. It has been proved to be an effective method for treating diabetes for many years. For patients, this miniature portable infusion pump is a very convenient device. It has been popularized in various countries in the world. The main brands are MINIMED in the United States, H-TRON in Switzerland, and DANA in South Korea. The prices are all tens of thousands of yuan, and the daily maintenance costs such as lithium batteries and other prices and quality are also issues that must be paid attention to. Now countries around the world The manufactured insulin pumps all use ultra-micro motors to drive high-precision syringes, which are expensive and difficult to popularize.

Another major defect of this device is the possibility of secondary pollution. Because high-precision micro-injectors have high requirements for materials and processes, and have different structures, they are usually imported with equipment and may be reused. When inhaling insulin medicine The requirements of aseptic operation cannot be guaranteed when liquid is used, and there is a risk of contamination

Based on the above reasons, it cannot be popularized in a large area in China at present, and can only be used in a small range, and its promotion and application are limited.
