Problems solved by technology

Self-testing of blood sugar plays a very important role in the management of blood sugar for diabetic patients, but the current blood glucose meter used to measure blood sugar is not easy to carry, and it is difficult for patients to detect blood sugar levels at any time when they go out. It is also difficult for patients to inject insulin at any time when they go out, and it is difficult to achieve accurate management of diabetes
In the prior art, there are devices based on multi-index detection sensors of transdermal microneedle arrays for measuring blood sugar concentration, and devices for realizing insulin injection through microneedle injection, for patients who also need to detect blood sugar levels and inject insulin when traveling or on business trips It is more convenient to measure and inject insulin, but it is necessary to carry the detection device and the injection device with you when using it, and there are many devices; and because the detection device and the injection device are small objects, it is easy to lose, and one of them After that, the functions of measurement and injection cannot be realized at the same time

Embodiment 1

[0028] Self-treatment device detecting the microneedles in the present embodiment can be applied to diabetes, attention is also applicable to other patients at any time using the detection and therapy.

[0029] Self microneedle treatment device comprising detecting the execution housing, and a fixing substrate is provided on the housing 1, sensors, micro-needle assembly, execution unit, the control member and drug source, wherein the substrate 1, and said control member is a member sequentially disposed on the housing. 1 the substrate 1 is a flexible substrate, to facilitate assembly piercing microneedle into the skin, and when the autonomous detector treatment device worn on the wrist, the wrist and the shape of the adapter housing, and the like may be provided to facilitate the wristband worn , beautiful and comfortable.

[0030] As the fact that the switchable manner, the drug may not be provided within the source housing, when in need of treatment, then the source of drug ther...

Embodiment 2

[0040] This embodiment is different from the above embodiment, such as figure 2 As shown, the microneedles include a first microneedle 2, a second microneedle 3, and a third microneedle 4 including a first electrode, a second electrode, and the first microneedle 2 is provided. The first electrode is provided on the first electrode; the second microneedle 3 is provided with a second electrode, the first electrode and the second electrode electrical connection. The third microneedle 4 is provided with an injection passage 5. The first microneedle 2 and the second microneedle 3 are used in the microneedle assembly for measurement, using the third microneedle 4 for injection, the microneedle assembly simultaneously participates in the function of measurement and treatment, so that the integration of the microneedle self-assisted treatment device Higher, the volume is smaller.

Abstract

The invention relates to the technical field of medical instruments, and in particular, to a micro-needle self-service detection and treatment device. The device comprises a substrate, a sensor, a micro-needle assembly, an execution part and a control part; the micro-needle assembly is arranged on the substrate, and comprises at least two micro-needles; at least one micro-needle is provided with an injection channel suitable for communicating with a medicine source; the at least two micro-needles are respectively provided with the electrodes, and the at least two electrodes are electrically connected to each other; and in the at least two micro-needles provided with the electrodes, at least one electrode is provided with an indicator. After the micro-needle assembly pierces the skin, the indicator can catalyze indicator molecules in subcutaneous tissue fluid for reaction, so that the sensor can detect actual indicator data parameters; and a control module judges whether the execution part needs to be controlled to inject medicines into the injection channels for medicine treatment. Manual intervention is not needed, and convenient use is achieved; and the device can simultaneously achieve measurement and treatment functions and is higher in integration level.

Description

Technical field [0001] Technical Field The present invention relates to medical devices, more particularly to a self-detecting microneedle treatment device. Background technique [0002] Diabetes is a group of metabolic diseases characterized by hyperglycemia. Hyperglycemia is due to insulin secretion defects or their biological impairment, or both thereof. Diabetes is a long-standing symptoms of high blood sugar, it can lead to a variety of organizations, especially the eyes, kidneys, heart, blood vessels, nerves and chronic damage, dysfunction. Management of blood glucose in patients with diabetes, the blood glucose self-testing plays a very important role, but there used to measure blood glucose meters are not easy to carry, the patient is difficult to detect blood sugar levels at any time while on the go, at the same time, the insulin pump is not easy to carry, in patients with insulin injections while on the go at any time is difficult, it is difficult to achieve precise man...
