A coating structure for implantable biosensor production

Abstract

The invention discloses a coating film structure for the production of implantable biosensors, which comprises a mounting part, and a coating film part for grabbing the film liquid in a drop shape is formed on the mounting part, and the coating film part is formed to be useful In the coating cavity for storing the drop-shaped membrane liquid, a coating channel for the implantable biosensor to pass through is opened on the side of the coating part away from the installation part, and the coating channel is connected with the coating cavity. The cavities are connected, so that the film liquid is coated in the form of droplets instead of the traditional film form, and the integrity of the package, the uniformity and stability of the coating film are better. The amount of drop-shaped film liquid is much larger than that of film-shaped film liquid, which can reduce the number of coating films, thereby greatly improving production efficiency.

Description

technical field [0001] The invention relates to the technical field of implantable biosensors, in particular to a coating film structure for the production of implantable biosensors. Background technique [0002] Blood glucose monitoring is very important for diabetic patients, and blood glucose values ​​help to assess the disorder of glucose metabolism in diabetic patients. At present, blood glucose detection can be divided into in vitro detection after blood collection and real-time detection by implanted blood glucose sensors. When blood sugar is controlled by in vitro detection after blood collection, blood must be collected multiple times a day, which brings a heavy burden to the patient's mind and body. Therefore, the method of real-time detection with implantable blood sugar sensors is becoming more and more popular. [0003] At present, the continuous blood glucose monitoring products that can be used in clinical practice are technically verified to a certain extent...

Problems solved by technology

However, because the invention patent uses the method of film liquid circle to coat the film, it still cannot operate the workpiece with both ends fixed during the operation, or if the two ends of the sensor are fixed, the film circle cannot pass through. Sensor for coating work

[0004] and the Chinese invention patent whose publication number is CN104941859B discloses a kind of sensor coating equipment, and its coating film is a coating film clamp, and the middle of the coating film clamp can be provided with a After immersion in the coating film gap of the workpiece coating film, the liquid forms a film-like liquid film in the coating film gap. First of all, the wrapping property of the liquid film is not enough, and secondly, the amount of liquid captured by the coating film clamp is also limited, so The number of times that the film needs to be coated will also increase accordingly. Finally, the thickness of the liquid film is uneven under the traction of gravity and surface tension, and it is easy to appear thin at the top and thick at the bottom. The thickness of the biofilm on the electrode surface itself is relatively thin, and a small difference in thickness may have a great impact on the detection accuracy of the sensor electrode
