Problems solved by technology

This method is not only time-consuming and labor-intensive, but also has low operating efficiency, and it will miss high blood sugar levels at many moments, so that patients' high blood sugar levels cannot be corrected in time, resulting in more high blood sugar levels in patients, and high doses of insulin are used once. High blood sugar will cause a sharp drop in blood sugar, forming a long-term violent fluctuation of blood sugar, which seriously affects the patient's health

Embodiment Construction

[0038] The present invention will be further described in detail below through specific embodiments and accompanying drawings.

[0039] figure 1It is a schematic composition diagram of an embodiment of the closed-loop drug delivery system of the present invention. see figure 1 , the closed-loop drug release system specifically includes:

[0040] A sensing tag 101, the sensing tag 101 specifically includes a subcutaneous body 201 and an extracutaneous body 202; the subcutaneous body 201 is used for embedding under the skin, such as figure 1 The shown sensor tag 101 is embedded under the skin 100 . The subcutaneous body 201 has the magnetic elastic material 111 coated with the biological enzyme 112. The biological enzyme 112 is used to react with the subcutaneous analyte to decompose the corresponding derivative substance. The magnetic elastic material 111 The vibration frequency changes with the concentration of the derived substance; the extracutaneous body 202 is fixedly ...

Abstract

The invention discloses a closed loop medicine release system which comprises a sensing label. The sensing label comprises a subcutaneous body and an extra-cutaneous body. The subcutaneous body is provided with a magnetic elastic material coated with a biological enzyme, the biological enzyme reacts with a subcutaneous analyte to be resolved into a corresponding derived material, and vibration frequency of the magnetic elastic material varies along with the concentration of the derived material. The extra-cutaneous body is placed on the outer side of the skin. A magnetic substance detector is used for applying magnetic induction to the magnetic elastic material, detecting the vibration frequency of the magnetic elastic material and determining the corresponding analyte concentration level according to corresponding relations of a pre-stored vibration frequency value and the analyte concentration level. A medicine release device determines a dose of to-be-released medicines according to the analyte concentration level and releases the medicines according to the dose. By utilizing the closed loop medicine release system, the dose of the released medicines can be automatically adjusted according to the in vivo analyte concentration level, and control accuracy of the in vivo analyte concentration level is improved, and the health level is improved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a closed-loop drug release system. Background technique [0002] At present, drug release devices have been widely used in the treatment of diseases. For example, there is currently an insulin drug release pen, which is a pen-shaped drug release device, which mainly includes: a needle, an insulin refill, a drug release mechanism, and the like. What's more, there is also an insulin pump now, which includes a drug release mechanism that stores the drug and releases the drug to the outside. The drug release mechanism includes a push mechanism, a drug storage device, a catheter and a needle. The insulin in the drug device is pushed to the catheter, and the insulin is sent into the needle along the catheter, and the needle is embedded into the subcutaneous of the patient, and the insulin is sent from the needle into the subcutaneous of the patient, so that the function of releasing the...
