Problems solved by technology

This kind of blood collection tube is made of a glass tube with a small inner diameter and two ends open and connected. When collecting blood, one end of the blood collection tube is in contact with the blood to be collected. Using the principle of capillary, the blood to be collected automatically enters the inside of the micro blood collection tube, but Existing blood collection tubes only have one range for blood collection, which is inflexible to use

Abstract

The invention discloses a blood sampling device with stepless capacity adjustment. The blood sampling device comprises an air bag, a piston, a connecting ring, a connecting tube, a blood sampling tube, a driving device, a resetting device and a floating mechanism; and the floating mechanism comprises a telescopic ring, an elastic film and a moving tube. According to the invention, a connecting screw rod is clamped and rotates on a positioning plate, a threaded cylinder is driven to move up and down through a thread occlusion principle, the connecting tube is driven to move up and down, the lower end of the connecting tube abuts against the moving tube to move downwards when the connecting tube moves downwards, the moving tube abuts against a guide column to move downwards on the elastic film, an elastic abutting and pressing piece abuts against the guide column upwards when the connecting tube moves upwards, and the guide column abuts against the movable tube upwards to enable the movable tube to move upwards on the elastic film, so that the purpose that the movable tube moves up and down on the elastic film is achieved, and the technical effect of stepless capacity adjustment is achieved.

Description

Technical field [0001] The invention relates to a blood sampling device with stepless adjustment of measuring range. Background technique [0002] Blood collection tubes are commonly used tools in hospitals and other medical departments when analyzing blood. This blood collection tube is made of a glass tube with a small inner diameter and open at both ends and connected. When blood is collected, one end of the blood collection tube is in contact with the blood to be collected, and the capillary principle is used to automatically enter the micro blood collection tube. The existing blood collection tube only has a form of one range for blood collection, which is not flexible in use. Summary of the invention [0003] In view of the above-mentioned shortcomings of the prior art, the problem solved by the present invention is to provide a blood sampling device with an infinitely adjustable range. [0004] To solve the above problems, the technical solutions adopted by the present inve...
