Dosage-controllable rapid analgesic injection device for battlefield

Abstract

The invention relates to a dosage-controllable rapid analgesic injection device for a battlefield. The injection device comprises a hollow pen body and a compressed spring in the pen body, wherein a pressing bar threads out one end of the pen body, a needle is arranged at the other end of the pen body, the pressing bar is abutted against a head end of the arranged compressed spring in the pen body, and a tail end of the compressed spring is abutted against a bulge of the internal wall of the pen body; the needle communicates with one end of a drug bin in the pen body, and the other end of the drug bin is provided with a pressing part for extruding contents of the drug bin; and thorn strips are further arranged between the pressing bar and the internal wall of the pen body, top ends of the thorn strips are abutted against the pressing part of the drug bin, and a reverse stopping ratchet which is used for pushing the thorn strips towards a drug bin direction is arranged aside the pressing bar. The injection device has the beneficial effects that the convenience of injection and the controllability of injection dosage can be improved through controlling and setting the storage type drug bin and pressing times, and the difficulty of injecting in a battlefield environment can be lowered.

Description

technical field [0001] The invention relates to the field of battlefield medical care, in particular to a rapid injection device that can cooperate with a preset medicine compartment, has controllable dosage and protects needles. Background technique [0002] Severe pain is one of the most common symptoms of war wounded. A large number of studies have shown that pain in the early stage of war trauma has a huge impact on the body's physiology, psychology, and rehabilitation. It is necessary to realize self-rescue, mutual rescue, analgesic administration or rescue of personnel in the early stage Rapid analgesic administration. [0003] At this stage, injection administration will still be the main way of early trauma analgesia, such as commonly used morphine injection and ketamine injection. At present, in emergency situations, especially for moderate to severe pain, conventional injection analgesics are difficult to complete in the first-line treatment of the wounded. It is ...
