Convenient-to-use drug delivery device for delivery nursing

Abstract

The invention discloses a convenient-to-use drug delivery device for delivery nursing, and relates to the technical field of delivery. The device comprises a needle cylinder, wherein a piston is arranged in the needle cylinder; a threaded cap is clamped in the piston; the threaded cap is internally in threaded connection with a threaded rod; both the left end and the right end of the threaded rodare fixedly connected to rotating devices; the rotating devices are clamped in the needle cylinder; a left rotating device is clamped in a first gear; and the first gear engages with a second gear. According to the convenient-to-use drug delivery device for delivery nursing, a pull plate, a toothed rod, a third gear, the second gear, the first gear, the threaded rod, the threaded cap and a suctiondisc coordinate with one another, so that the problem that a needle head is deviated due to the easy shake of manual control of medical worker is solved, the problem that the medical worker carries out rough injection by manually pushing the piston is solved, the drug delivery amount can be better controlled, and the accuracy of the drug delivery amount is improved.

Description

technical field [0001] The invention relates to the technical field of childbirth, in particular to an easy-to-use drug delivery device for childbirth care. Background technique [0002] During the delivery process, although the parturient has been injected with a certain amount of anesthetic drugs in advance, due to the physical condition of the parturient and the prolongation of the operation time, the anesthetic effect of the parturient during childbirth is gradually reduced, making it necessary to further administer drugs to the parturient. The drug delivery device cannot be fixed to a certain extent, so that when the medical personnel inject the drug, the manual control is prone to certain vibrations, resulting in a certain deviation. At the same time, the drug delivery device can only be roughly pushed and injected manually by the medical personnel. It makes it difficult for medical personnel to control the dosage by manual direct push operation, thereby affecting the ...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides an easy-to-use drug delivery device for childbirth care, which solves the problem that ordinary drug delivery devices cannot perform a certain fixing effect, so that when medical personnel inject drugs, manual control is easy to occur. Certain vibrations lead to certain deviations. At the same time, the drug delivery device can only be pushed and injected manually by medical personnel, which makes it difficult for medical personnel to control the dosage by manual direct push operation, thus affecting the accuracy of the dosage.
