Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary products, in particular to an anti-pollution venous blood sampling device. Background Art

[0002] Bioequivalence (BE) is one of the key tasks of the ongoing quality and efficacy consistency evaluation of generic drugs in my country. It is also currently recognized as an effective means to measure the quality and efficacy of generic drugs. Its purpose is to prove the bioequivalence of generic drugs and reference products, so as to bridge the preclinical trials and clinical trials related to the reference products.

[0003] In recent years, with the increasing prevalence of respiratory diseases and people's in-depth understanding of diseases such as asthma and chronic obstructive pulmonary disease, it has become a global consensus that inhalation is the preferred route of administration for the treatment of the above diseases. Orally inhaled drug products (OIDPS) refer to preparations that deliver drugs to the respiratory tract and / or lungs by inhalation to exert local or systemic effects. Compared with ordinary oral preparations, the drugs in inhaled preparations can directly reach the absorption or action site, with rapid absorption, avoiding the first-pass effect of the liver and reducing the dosage of the drug. Compared with injectable preparations, inhaled preparations can improve patient compliance and reduce or avoid some adverse drug reactions.

[0004] When conducting Phase I clinical trials of inhaled dosage forms of drugs, inhaled preparations usually need to be delivered through a drug delivery device. After the drug is administered by the drug delivery device, the drug is first delivered to the site of action and then enters the systemic circulation, while also passing through other sites, such as the mouth, pharynx, gastrointestinal tract, etc.; after the drug enters the systemic circulation, it is necessary to collect blood from subjects at different time periods and measure blood drug concentrations at different time periods to obtain real data; when administering the drug, inhaled dosage forms are easily dispersed into the surrounding environment, so when collecting blood from subjects, the blood collection site and blood collection equipment must not be exposed to the air to prevent the blood from being contaminated by the inhaled dosage forms dispersed in the surrounding environment and resulting in false data.

[0005] Therefore, how to design an anti-contamination venous blood collection device that avoids the exposure of the blood collection site and blood collection equipment to the air when collecting blood from the subject, and prevents the blood from being contaminated by inhalation dosage drugs dispersed in the surrounding environment and causing false data, is a technical problem that has not yet been solved in the prior art.
