Self-destroying pre-filling type wash pipe injector

Abstract

The invention discloses a self-destroying pre-filling type wash pipe injector which comprises a sleeve, a piston and a pull rod. The sleeve at least comprises a sleeve body, a blocking fin, an inner threaded pipe, an outer thread cap and a butt-joint intubation tube. The front end of the outer thread cap is provided with a sealing end cover which makes close contact with the butt-joint intubationtube so as to achieve sealing. The piston is connected to the inner wall of the sleeve in a sealed mode. The pull rod is arranged at the lower end of the piston. According to the self-destruction pre-filling type wash pipe injector, the internal thread pipe can be sealed through the outer thread cap and the sealing end cover, and when the self-destruction pre-filling type wash pipe injector is used, the outer thread cap is unscrewed, and then the butt-joint intubation tube is connected with infusion equipment; and the infusion equipment at least comprises a PICC and an infusion port. Accordingto the self-destroying pre-filling type wash pipe injector, secondary use can be avoided through failure of the piston or the pull rod, and then the self-destroying effect is achieved.

Description

technical field [0001] The application relates to the technical field of medical devices, in particular to a self-destruct prefilled flushing syringe. Background technique [0002] In clinical infusion, before the prefilled syringe is used, the infusion liquid in the prefilled syringe must maintain the tightness and integrity to achieve the best drug effect, that is to say, the prefilled syringe must not only be in an undamaged state, At the same time, the first contact with the infusion liquid should be done when the patient uses it. However, in the prior art, due to the poor sealing of prefilled syringes in the different specific sterilization processes pretreated before leaving the factory (such as steam sterilization and many other sterilization methods in the pharmaceutical industry), leakage is likely to occur. liquid, thereby affecting the efficacy of the drug. [0003] Syringes are the most common disposable medical devices. Prefilled syringes are more expensive th...
