A collection or detection device used to release, collect, or detect specific substances. [Prior art] The route of drug delivery is% in the treatment of drug diseases. At present, Huawu Tanyangshi 4 y Tian Zhiyao 10 15 Oral and injection are mainly oral and injection, but = 筚: Pleasure delivery method, because there are many shortcomings, so the limitation is obvious, such as drug delivery Disadvantages; disadvantages of music delivery, such as selectivity, control of drug control convenience, and selection of the treatment site all limit the application of drug delivery. Taking the oral drug method as an example, when the drug enters the stomach from the esophagus, the effect is reduced. Especially the structure of the second bad drug makes the therapeutic dosage form, so η%, shellfish, and shellfish. These drugs are currently not administered by oral tA " ^ / primary injection mode, so the use of π-medicine drugs has been narrowed. / σ treatment, often must :: 筚 Si: to an effective therapeutic effect, within the control range of drug administration, while the concentration of ΓΓ is maintained at an effective therapeutic concentration to maintain the concentration of the drug. Way to come in 4_ The change is relatively large and the concentration is unexpected. Furthermore = 20 1242455 In the early stage of administering the drug, if the concentration of the drug in the blood is too high, it may be toxic and affect the body. But at the same time, at the end of the drug's duration, the therapeutic effect is not achieved. Therefore, how to control the concentration of the drug in the blood ^ 5 10 15 and to avoid the inability to control the concentration of the drug in the blood, or to significantly reduce the therapeutic effect, are topics that are important for general oral or injection administration methods.疋 Non-load-bearing Purely in terms of pharmacology, ‘directing the drug to the target area is an effective method of administration. However, the general oral or injection drug delivery method is to deliver the drug to the treatment area through a systemic delivery method, so it is not a specific treatment method. In addition, oral or injection administration / dosage is required, which requires a larger amount of medicine than direct administration to the target area. Its administration efficiency is low, and the drug needs to be delivered systemically, which easily causes drug side effects. 0 In addition, traditional oral or injection administration Drug treatment is quite inconvenient for patients who are treated with drugs. Patients with diabetes U must take oral hypoglycemic drugs daily or by injection: to control their condition. And in terms of the dangers of drug use, self-oral medicament methods often cause excessive use of drugs or intermittent use of drugs due to human factors, and the right use of injectable drugs for treatment, for patients not only accompanied by the burden of pain ' Crisis of infection caused by potential injection contamination. Because of the above-mentioned disadvantages of delivering drugs by oral and injection methods, mesh knife = development of swallowable or implantable drug release systems, the following will be two eyesight = several solutions. U.S. patent case number is still rampant, Chuan 8 series disclosed injectable drug release system, which uses several microfluidic devices and catheters 20 1242455 to left the drug knife into the treatment area 'however' most of this implant system can only deliver liquid drugs The drug delivered is in the device or the outlet of the catheter, and there may be fibrous soil at the outlet of the catheter, so there are still many shortcomings to be improved in use. Moreover, the design and production complexity of this planting type = release system is very high. 'Usually it has a mechanism design, which requires a lot of components, so the risk of system and system failure is increased, and most of the current known people are single-slot design. If its single catheter outlet or: trough failure, failure of the placement of silk or misadministration, the risk is higher / ίο 15 / US Patent Case No. US517, 〇8 () 1 _Lu-a swallowable drug release system ' To improve the disadvantages of oral administration. Its effect is to release the drug in specific areas of the digestive tract. This case uses a swallowable capsule design to achieve the swallowing function. Its main structure can be divided into two layers, the outer and outer layers are designed to release opening pores, and the inner and outer layers have open pores with a thermal rotation mechanism. Correspondingly, so that the drug molecules can be released from the pores. The thermal rotation mechanism uses shape memory alloys (Shape Memory Alloys, SMA) to drive the rotation mechanism, and uses wireless transmission to control the release of objects. However, this design has many shortcomings to be overcome. For example, it can only be put into the stomach for treatment for a short time. Currently, it can only be loaded with a single therapeutic drug, and the design of the revolving opening may cause blockage of the release outlet, and the opening can only be-fully open or fully closed. If the opening is repeatedly opened for use, it is easy for the body fluid to penetrate into the medicine tank 'and cause the medicine to deteriorate and destroy, and the outlet may have the problem of fiber coating. Furthermore, it has a single-slot design and is highly dangerous. In addition, US patent cases US579,7898 and US6,5; 27,762 disclose an implantable drug release system, which uses micro-electromechanical (MEMS) technology and 20 I242455 15 κ process technology to achieve functions such as a miniature multi-drug tank. This design uses Shi Xi as the base material, which can be completed by repeating complex processes such as development, button engraving, and deposition. The cavity, electrical control layer, filling, and tank cover must be made in sequence, and cannot be processed in parallel. The front-to-back process is easy to restrain each other, which is much more difficult. The process of making the cap after filling is more likely to destroy the original characteristics of the drug due to temperature or other reactions. The drug molecule release mechanism is divided into passive and active. In the basin, the = dynamic release mechanism is mainly osmotic, and the active release mechanism is transparent. The temperature change is controlled to make the lid of the drug tank transparent. Structure to release the drug. There are also many disadvantages to this design. For example, different transparent cover designs are complicated and time-consuming in the MEMS manufacturing process. And because the ::: type or rupture drug tank is opened to release the material, it cannot solve the problem of cell blockage and blockage, and there will be obstacles to drug delivery. Tian ..., the export also has the problem of fiber coating. The description of the release 2 shows that “Although there are many ways to solve the problem of drug release”, there are still many shortcomings mentioned above. Therefore, “how to design the Le system” to avoid the problems faced by the implantable release method on the traditional drug delivery route. The problem of drug delivery (fibrosis) clogging the drug release outlet of the physiological and immune response has made non-purpose reliability, miniaturization, and accuracy, and reducing other side effects of fun, has become an urgent problem. [Summary of the Invention]-A lack of know-how, the purpose of the present invention is to provide an actuating and retracting device that can be implanted in a living body to release a compound 20 1242455 (such as a pharmaceutical compound) or a composition (such as a pharmaceutical combination).
