Problems solved by technology

[0002] Compared with the drug delivery device in the prior art, especially the drug delivery device for chemotherapy, it is often necessary to extract the drug in the chemotherapy drug during its use, and then inject it into the patient's body, and in this process There is often the fact that the medicine cannot be completely sucked out, and the medicine liquid is easy to leak out during the injection process, which will cause a certain loss and prevent the patient from receiving complete chemotherapy. Therefore, we propose a medicine with Extravasation-proof chemotherapy drug delivery device

Abstract

The invention provides an extravasation-proof chemotherapy drug administration device and relates to the field of drug administration devices. The extravasation-proof chemotherapy drug administrationdevice comprises an injection tube, wherein the left end of the injection tube comprises an injection head, anti-slipping teeth, a clamping block, connection rods, anti-slipping fingerstalls, limitingblocks, torsion springs, buckles, a needle head and a suction disc. According to the extravasation-proof chemotherapy drug administration device, a drug administration tube is arranged, and a threadsleeve, a thread tube, a medicine liquid bottle, a rubber plug, a separation block, a fixed block, a liquid entering head, a pricking tube and liquid leakage through holes are matched to use; after the medicine liquid bottle is in thread connection with the thread sleeve through the thread tube, the pricking tube on the fixed block can be pricked into the rubber plug on the medicine liquid bottle,so that medicine liquid in the medicine liquid bottle is reversely poured and flows into the liquid entering head through the pricking tube and medicine liquid is dropped into the injection tube through the liquid entering head, and furthermore, the medicine liquid extravasated from the rubber plug can flow into the injection tube through the liquid leakage through holes on the separation block;therefore, the medicine liquid in the medicine liquid bottle can completely flow into the injection tube.

Description

technical field [0001] The invention relates to the technical field of drug delivery devices, in particular to a chemotherapy drug delivery device with extravasation prevention. Background technique [0002] Compared with the drug delivery device in the prior art, especially the drug delivery device for chemotherapy, it is often necessary to extract the drug in the chemotherapy drug during its use, and then inject it into the patient's body, and in this process There is often the fact that the medicine cannot be completely sucked out, and the medicine liquid is easy to leak out during the injection process, which will cause a certain loss and prevent the patient from receiving complete chemotherapy. Therefore, we propose a medicine with Extravasation-resistant chemotherapy applicators. Contents of the invention [0003] The purpose of the present invention is to provide a novel and reasonable structure, which can completely suck out the drug solution and stabilize the ext...
