Description

A drug delivery device for critically ill medicine

technical field

The invention relates to the technical field of drug delivery devices, in particular to a drug delivery device for critical and critical medicine.

Background technique

Medical treatment has the meaning of healing. In medical treatment, the rescue time of critically ill patients is more valuable. During the treatment of critically ill patients, sometimes medical staff will inject drugs to patients to relieve symptoms, improve patient function, and administer drugs. Therapy is the most common form of treatment.

At present, injection and drug delivery use a syringe to inject medicinal liquid into the patient's body. Sometimes it is necessary to inject an accurate value of medicinal liquid. Once the medicinal liquid is too much or too little, medical staff generally look at the scale on the drug cartridge when extracting medicinal liquid. , extract some less, and push some more, this operation needs to be careful, for rescuing patients, time is precious, and it is easy to lead to wrong optimal treatment time. Secondly, the connection between the drug cartridge on the syringe and the connector The tightness is average, and sometimes the connector will accidentally fall off from the round tube. Also, after injecting the liquid into the patient, the patient cannot press the skin injection port, and the medical staff needs to help the patient, which is likely to cause a waste of manpower and needs to be improved.
