Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment biosensors, in particular to an implantable bio-diagnosis detection reagent sensor. Background Art

[0002] In the field of modern medical technology, instant, accurate, non-invasive or minimally invasive in vivo biomolecular detection technology is of great significance for early disease detection, treatment monitoring, and health management. However, existing in vitro diagnostic methods have problems such as insufficient timeliness and inability to continuously monitor changes in the body environment; and traditional implantable detection devices often have single functions and are difficult to achieve accurate and controllable drug release for specific biomarkers.

[0003] With the development of biomedical engineering, especially the progress of intelligent biomedical materials and micro-nano manufacturing technology, it is particularly urgent to develop an implantable bio-diagnostic agent sensor that can achieve real-time and accurate detection in the body and control drug release as needed. However, the implantable sensors in the prior art still have limitations in drug loading and release mechanisms, such as insufficient precision in drug release control or low integration of sensors and drug release systems, which limits their flexibility and practicality in practical applications. Therefore, we propose an implantable bio-diagnostic agent sensor. Utility Model Content

[0004] The main purpose of the utility model is to provide an implantable bio-diagnosis detection reagent sensor, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] An implantable bio-diagnostic detection reagent sensor comprises a sensor body, a detection probe is arranged at the front end of the sensor body, and two detachable grooves are arranged at the rear end of the sensor body. Four card slots are integrally formed on the outer surfaces of the two detachable grooves, and drug release mechanisms are detachably installed in the two detachable grooves through the card slots.

[0007] Preferably, the drug release mechanism includes a medicine tube, and a clamping strip that cooperates with the clamping slot is provided on the front surface of the outer surface of the medicine tube. The clamping strip is clamped in the clamping slot to fix the medicine tube to the disassembly slot. A joint is fixedly installed in the middle of the front end of the medicine tube, and the medicine tube is electrically connected to the sensor body through the joint.

[0008] Preferably, a heating element, a No. 1 sealing film and a No. 2 sealing film are provided on a side of the medicine tube away from the joint, and the heating element is located between the No. 1 sealing film and the No. 2 sealing film.

[0009] Preferably, the No. 1 sealing film and the No. 2 sealing film have the same structure and are both equal to the inner wall diameter of the medicine tube, and the No. 1 sealing film and the No. 2 sealing film are both made of low-temperature biodegradable materials.

[0010] Preferably, the heating element includes an outer fixing ring and an inner sleeve ring, the inner sleeve ring is coaxially arranged with the outer fixing ring, a plurality of connecting rods are integrally formed on the outer surface of the inner sleeve ring, and one end of the plurality of connecting rods away from the inner sleeve ring is fixedly connected to the inner surface of the outer fixing ring, and a release groove is arranged between two adjacent connecting rods.

[0011] Preferably, a controller is fixedly installed in the inner ring, and heating wires are fixedly installed in the plurality of connecting rods, and the plurality of heating wires are connected to the controller wires.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The drug tube is fixedly installed in the disassembly slot by connecting the card strip and the card slot, and the drug release mechanism is connected to the sensor body wire by the connector, which is convenient for disassembly and assembly of the drug release mechanism. The drug release mechanism with the corresponding drug can be selected according to the detection target, so as to achieve the purpose of convenient use, convenient disassembly and assembly, and strong practicality.

[0014] 2. When it is necessary to release the drug, the controller can be started to heat the heating wire through the controller, and the No. 2 sealing film and the No. 1 sealing film on both sides are heated by the heating wire. Since the No. 2 sealing film and the No. 1 sealing film are made of biodegradable temperature-sensitive materials, when the No. 2 sealing film and the No. 1 sealing film are degraded by heat, the drug is released through the release groove and used in conjunction with the sensor body to achieve accurate detection effects. Since there are two drug release mechanisms, the two drug release mechanisms can be used to release the drug separately in actual applications to achieve precise control of drug release.
