Description
Technical field
This utility model relates to being exclusively used in Mus arterial blood sample harvester.
Background technology
Mice has become as widely used laboratory animal in biomedical research at present, study the most detailed mammalian laboratory animals in the Ye Shi world today, be usually used in the research in the field such as hereditism and hereditary, oncology, infectious disease, medicine, immunology, endocrinopathy, presbyatrics.Along with being on the rise of global climate problem, correlational study confirms that atmospheric pollution is close with the morbidity of respiratory tract disease, cardiovascular disease, internal authority magazine JAMA in 2012 confirms that air pollution is a risks and assumptions of cardiovascular disease, and therefore the research in terms of respiratory tract, cardiovascular also gets more and more.With mice the animal models such as duplicated chronic bronchopneumonia, acute lung edema, bronchial asthma, chronic pulmonary hypertension, pulmonary fibrosis become research respiratory tract disease mechanism basis.We are in the experiment carrying out Respiratory Tract of Mice disease model, it is often necessary to gather arterial blood to mice and carry out arterial blood gas analysis.
Look back data of literatures, we gather rat aorta blood for blood gas analysis at present, great majority are all by detachment coeliac artery, then quick suction blood, or detachment mice right common carotid artery, or aspirate arterial blood with 1ml syringe acupuncture intravital mouse heart, or open brooch thorn right ventricle blood sampling.The shortcoming of these three kinds of methods: 1, gather tremulous pulse method for direct detachment or acupuncture coeliac artery: mouse peritoneal tremulous pulse is positioned at rear, abdominal cavity, position is deeper, need to fully expose mouse peritoneal, passage intestinal tube, manifests posterior wall of abdomen, removes retroperitoneal adipose tissue, the most visible ventral aorta, the biggest invasive manipulation, can affect the respiratory function of mice, and then affect the accuracy of rat aorta vim and vigour；Quick suction blood after detachment coeliac artery, arterial blood directly and air contact, can directly affect the accuracy of the important blood gas indexes such as partial pressure of oxygen, blood oxygen saturation, carbon dioxide dividing potential drop.2, syringe being punctured intravital mouse heart and adopt arterial blood shortcoming: 1. mouse heart is little, 470-480 time/min of heart rate, and Culling heart blood is relatively difficult, technology requires height, and operating process small mouse mortality rate is higher, is not suitable for the experimentation having strict demand to arterial blood；2. it cannot be guaranteed that collected is entirely arterial blood, because direction or the operational issue of inserting needle also extraction arteriovenous can mix blood, art pO2 and oxygen saturation can be caused substantially abnormal.3, split brooch thorn right ventricle: if opening breast once dead blood sampling, opens thoracic cavity, has completely cut through the respiratory function of mice, and before not gathering arterial blood, the index of correlation of arterial blood gas can occur significant change, affects the accuracy of experimental data.
To sum up, there is many deficiencies in the method that existing Mus arterial blood carries out using, and the collection being simultaneously used for Mus arterial blood sample uses conventional syringe to carry out, and owing to mouse heart, tremulous pulse etc. are less, technology requires height, the problems such as operating process small mouse mortality rate is higher.
Utility model content
This utility model utility model purpose: for the defect overcoming prior art to exist, a kind of blood specimen collection of this utility model offer is easy and simple to handle, safety, and little on mice impact, blood sample interference is few, and testing result is exclusively used in Mus arterial blood sample harvester accurately.
