<p>Disclosed is a portable programmable automated drug administration device comprising a driving component, a sleeve (5), a guiding bar (6) and a drug tube (7). The driving component comprises a rotation shaft (4) with an external thread thereon and a sleeve (5) outside; the external thread on the rotation shaft (4) is matched with the internal thread in the sleeve (5). The upper end of the guiding bar (6) is fixed on an upper fixed block (3) and the lower end is fixed on a lower fixed block (11); the sleeve (5) is adapted to the guiding bar (6). The driving component is connected with the drug tube (7) via the guiding bar (6). The cross-section of the sleeve (5) is adapted to the inner cavity of the drug tube (7). The lower end of the sleeve (5) is closed and extends to the inner cavity of the drug tube (7). The other end of the drug tube (7) is closed with a sealing cap (10). The drug tube (7) is connected with a drug diffusion part (8) via a micro-tube (9). The present device is compact in structure, portable, easy to use and a gearbox and a threaded connection are employed so that the control precision and the reliability of drug administration are improved.</p> |
