Embodiment 1

[0026] combine Figure 1-3 , an intelligent drug delivery system for joint damage, characterized in that it includes a computer 1, a relay controller 2, and a portable drug delivery box 3; the computer 1 is connected to the relay controller 2, and the relay controller 2 is connected wirelessly The portable drug delivery box 3; the portable drug delivery box 3 extends a drug delivery capillary hose 4, and the end of the capillary hose is provided with an intracavity drug delivery head 5;

[0027] The intracavity drug delivery head 5 is arranged at the joint damage by implantation, the portable drug delivery device box 3 can regularly and quantitatively deliver drugs to the intracavitary drug delivery head 5, and the portable drug delivery device box 3 monitors the intracavitary drug delivery head in real time 5, and control the drug concentration in the intracavity drug delivery head 5 within the allowable range.

[0028] The portable drug delivery device has a built-in contro...

Embodiment 2

[0040] This embodiment relates to a specific method of using the system of the present invention.

[0041] Before using the system, it is necessary to determine the drug to be used and the characteristic band of the drug. The determination of the characteristic bands can be carried out using a UV-Vis-Near Infrared Spectrophotometer. In addition, the daily standard concentration curve of the drug needs to be set in advance. The curve is the daily time-varying drug concentration requirement at the patient's site.

[0042] Then put the medicine into the medicine storage bag, and set the optical wavelength of the light source module to the characteristic band of the medicine; note that when setting here, try to avoid the interference of body fluids on the characteristic wavelength of the medicine. If there are multiple characteristic wavelengths, choose the least interference characteristic wavelength.

[0043] Puncture the joint of the patient, and implant the drug capillary t...

Abstract

The invention relates to an intelligent accurate drug delivery device for joint damage. Through remote computer control and real-time drug concentration monitoring, timing quantitative and accurate supply of a drug can be realized, that is, the accurate-position uninterrupted supply of the drug is realized without affecting patient action; when the real-time drug concentration monitoring is performed, light in a characteristic light band for the drug is used, so that the drug concentration can be detected more accurately. A designed intra-cavity drug delivery head that can be arranged in a joint position can be squeezed and deformed by a joint, so that the system can realize two functions of drug concentration detection and accurate drug delivery without affecting the movement of the joint, and the system can be applied to other application scenarios requiring continuous drug delivery.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an intelligent drug delivery system for joint damage. Background technique [0002] Precise drug administration generally involves two aspects. On the one hand, the precise location of drug administration requires that the drug be delivered to the affected area as directly as possible. On the other hand, the amount of drug administration requires precise control. To calculate the precise dosage, doctors need to frequently collect blood from patients and analyze the blood samples in real time. This method one is very troublesome, and the other is very big to the harm of patient. [0003] Application number: 201910288886.7 discloses an anorectal inspection and drug delivery device that can achieve precise drug delivery, including a fixed base plate, a rotating plate for adjusting the degree of expansion, N arc-shaped expansion plates for achieving anal expansion, and for feeding to ...
