Problems solved by technology

The use of subcutaneous implanted sustained-release capsules can overcome the above-mentioned defects of intravenous and intramuscular injections to a certain extent, which brings great convenience to patients and significantly reduces the risk of trauma and infection for patients. Sustained-release capsules have the disadvantages of limited drug use time, inability to adjust the medication regimen at any time, and the inability to add additional drugs

Embodiment 1

[0036] In this embodiment, the flow-controllable internal medication device includes a drug storage bag 2, a drug feeding mechanism 1, a bar-shaped drug delivery tube 3, a program-controlled switch 6, a loading plate 5, a first electronic control system, a first A 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-chip microcomputers (produced ...

Embodiment 2

[0042] In this embodiment, the flow-controllable internal medication device is different from Embodiment 1 in that:

[0043] 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].

[0044] 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].

[0045] 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; The switch 6 is two pairs, which are respectively arranged on two grooves on the loading plate of the Y-shaped controlled section of th...

Abstract

An in-vivo medicine dosing device having a controllable flux comprises at least one medicine storage bag, medicine dosing mechanisms in the same number as the medicine storage bag, a medicine conveying pipe, a program control switch, a loading plate, 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 medicine storage bag, a medicine inlet section of the medicine conveying pipe, and the loading plate which is provided with the controlled section of the medicine conveying pipe and the program control switch are packaged inside at least one box which is embedded in the skin of the patient in use; the medicine dosing mechanisms are embedded in the skin of the patient; a medicine outlet section of the medicine conveying pipe is located in the abdominal cavity, the chest, the cranial cavity, the muscle, the skin, or the like of the patient. The second electronic control system is located outside the patient; and the second electronic control system is used for sending medicine conveying instructions, and is used for receiving and displaying medicine conveying information by the operator.

Description

technical field [0001] The invention belongs to medical equipment, in particular to a device which can be implanted into a human body and can intelligently control the dosage of medicine. Background technique [0002] Some patients with chronic diseases (such as diabetes, tumors, menopausal hormone deficiency, etc.) need long-term medication, but for patients with poor compliance or who are not suitable for oral medication, there are repeated medications whether it is intramuscular injection or intravenous injection. Punctures lead to the risk of trauma and infection. 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 labor intensity of medical staff. Sustained-release medication technology is an emerging medication method in recent years. By embedding sustained-release capsules subcutaneously, the drug is slowly released into the subcutaneous area through the capsu...
