Problems solved by technology

However, due to the limited amount of drug contained in the sustained-release capsule, it cannot be added after the drug is used up, so this medication method brings convenience to the patient and has a time limit, which cannot meet the long-term use of the patient.
Moreover, when the sustained-release drug is used up, if you need to continue to use it, you need to re-operate to embed the sustained-release capsule in the patient's body, which increases the trauma and pain of the patient.
[0003] Since the sustained-release medication technology adopts the principle that the drug can diffuse from high concentration to low concentration under the concentration gradient, the release rate of the drug is constant, and the drug can only exert its effect on the whole body after being released into the subcutaneous layer and absorbed, so it cannot meet the requirements of The problem of intelligent control of drug dosage and drug time cannot meet the needs of local drug treatment for some diseases

Embodiment 1

[0037] In this embodiment, the implantable intelligent control body medication device includes a drug storage bag 2, a drug feeding mechanism 1, a bar-shaped drug delivery tube 3, a programmable switch 6, a drug injection pump 7, a loading plate 5, a first An electronic control system, a first power supply, a second electronic control system and a second power supply. The first electronic control system such as figure 1 As shown, it consists of a first single-chip microcomputer and a first wireless receiver and a first wireless transmitter respectively connected to the first single-chip microcomputer. The second electronic control system such as figure 1 As shown, it consists of a second single-chip microcomputer, a second wireless receiver connected to the second single-chip microcomputer, a second wireless transmitter, human-computer interaction buttons and a display. Both the first single-chip microcomputer and the second single-chip microcomputer are MSP430F135 single-ch...

Embodiment 2

[0043] In this embodiment, the flow-controllable internal medication device is different from Embodiment 1 in that:

[0044] 1. There are two drug storage bags 2, two drug feeding mechanisms 1, and the drug delivery tube 3 is a Y-shaped tube. The bottom of each medicine storage bag 2 is respectively connected with the two upper arms of the Y-shaped tube drug delivery tube 3 [as Figure 4 (2) in Figure].

[0045] 2. The loading plate 5 is provided with a Y-shaped groove that matches the drug delivery tube 3 (such as Figure 6 (2) in Figure].

[0046] 3. In the combination formed by the drug storage bag, the drug feeding mechanism and the drug delivery tube, part of the medicine feeding section, the controlled section and part of the drug delivery section of the drug delivery tube are located in the Y-shaped groove set on the loading plate 5; There are two sets of switches 6, which are respectively arranged at two grooves on the loading plate where the Y-shaped controlled sec...

Abstract

The invention discloses an implantable intelligent in-vivo drug use control device. The implantable intelligent in-vivo drug use control device comprises at least one drug storage bag, a drug adding mechanism of which the number is the same with the number of the drug storage bag, a drug conveying pipe, a programmed switch, a loading plate, a drug infusion pump, a first electronic control system, a first power supply, a second electronic control system and a second power supply; the first power supply, the first electronic control system, the drug storage bag, the drug inlet section of the drug conveying pipe, the controlled section provided with the drug conveying pipe, the programmed switch and the loading plate of the drug infusion pump are encapsulated in at least one box body. When using, the implantable intelligent in-vivo drug use control device is embedded under the skin of a patient, the drug adding mechanism is embedded under the skin of the patient, and the drug outlet section of the drug conveying pipe is arranged in the abdominal cavity, chest, skull and muscle, under the skin or the like; the second electronic control system is located outside the patient body and used for sending a drug conveying command and receiving and displaying the drug conveying information.

Description

technical field [0001] The invention belongs to medical equipment, in particular to a device for implanting in the body for medicine. Background technique [0002] With the advent of an aging society, the drug treatment of chronic diseases and cancers has become an increasingly serious problem in the medical field. Some patients may need long-term medication through intravenous or intramuscular injection, but whether intramuscular or Medication undoubtedly increases the risk of trauma and infection caused by repeated punctures for patients with low resistance. At the same time, patients need to travel frequently to medical institutions, which seriously affects the daily life and work of patients, and also increases the work intensity of medical staff. Sustained-release medication technology is an emerging medication method in recent years. Sustained-release capsules are embedded subcutaneously through surgery, and the drug is slowly released through the capsule wall to the s...
