Drug delivery system for surgical nursing

Abstract

The invention provides a drug delivery system for surgical nursing. The drug delivery system comprises a grinding device, a detection device, a supply device, a conveying device, a sensing device anda processo; the grinding device is configured to grind a drug; the detection device is configured to detect the drug and pass through the supply device and the conveying device; the supply device is configured to perform supply operation on the drug; the conveying device is configured to convey the drug to a user side; and the sensing device is configured to sense the supply amount of the drug. The conveying device is used in cooperation with the detection device and the supply device, so that after drug of the detection device enters the conveying device, the drug is conveyed to a focus underthe conveying operation of the conveying device, and it is guaranteed that the drug can directly act on a wound or the focus.

Description

technical field [0001] The invention relates to the technical field of drug measurement, in particular to a drug delivery system for surgical care. Background technique [0002] In the existing drug delivery device, although it has a drug metering effect, the metering device is relatively complicated, and the drug dosage is controlled by adjusting the air supply volume or the gas output volume, which leads to difficulties in accurate metering of the drug dosage, and has a great impact on the device. The precision requirements are high, and there are currently disadvantages of low efficiency and thermal energy utilization. [0003] For example, CN107073199B prior art discloses an automatic drug delivery device for delivering liquid drugs. Drug injection devices, such as automatic injection devices, can reduce drug preparation / management and reduce needle damage, which will be more convenient and easier for patients. High compliance. As a result, more patients and healthcare...

Problems solved by technology

Another typical dry powder drug delivery system disclosed in the prior art such as WO2012171443A1, and a self-driven drug injection device and injection method disclosed in the prior art such as WO2018099472A1, the existing storage type dry powder drug delivery device For commercially available products, the air inlet / hole communicating with the flow channel is usually opened on the housing. When the protective cover / shell of the dry powder drug delivery device is removed, the air inlet is exposed to the air. As a result, the air path in the dry powder drug delivery device that communicates with the powder container is always in a "normally open" state that communicates with the outside world, and the moisture contained in the outside air can easily enter the powder container, causing the dry powder in the powder container to easily " Agglomerated by damp, affecting the accuracy and use effect of dosing and metering

[0004] In order to solve the common problems in the field of inaccurate measurement, poor dosing accuracy, easy to cause moisture, agglomeration, failure to grind, etc., the present invention is made
