Blood separating gel filling machine

Abstract

The invention relates to a blood separating gel filling machine used for equipment for filling the blood separating gel in the process of producing disposable vacuum blood tubes. The blood separating gel filling machine comprises a rack, a thermostatic heater and a quantitative filler, wherein the quantitative filler comprises a body, a filling head, a push rod, an adjusting plate, a connector, acylinder and a glue barrel; the body is arranged above the rack and is provided with a quantitative cavity; a glue inlet is arranged on the upper part of the quantitative cavity and a glue outlet is arranged on the lower part of the quantitative cavity; the glue barrel is arranged above the body; the glue outlet of the glue barrel is connected with the glue inlet of the quantitative cavity; the filling head is arranged at the glue outlet on the lower part of the quantitative cavity and is provided with a glue filling hole; a spoiler is arranged at the lower end of the glue filling hole; the push rod is arranged in the quantitative cavity; the cylinder is arranged above the rack and is provided with a piston and a piston rod which is connected with the push rod by the connector; and the thermostatic heater comprises a temperature controller, an electric heating tube, a solid-state relay and a temperature sensor.

Description

technical field [0001] The invention relates to a blood separation glue filling machine, which is used for filling blood separation glue in the production of disposable vacuum blood collection tubes. Background technique [0002] Blood separation gel is an important raw material for the production of disposable vacuum blood collection tubes. Its physical and chemical properties are very special, its viscosity is very high, and it is not easy to package at room temperature. According to the national standard, the weight of blood separation gel added to each blood collection tube is 1g±10%. When the manufacturer purchases blood separation gel, it is generally 25Kg in a barrel. When the manufacturer transfers on the production line, it is easy to mix air, which leads to a reduction in the amount of glue added. At the same time, the viscosity of the blood separation gel is quite high. When the operation is not careful, the glue thread will stick to the inner wall of the test ...

Problems solved by technology

When the manufacturer transfers on the production line, it is easy to mix air, resulting in a reduction in the amount of glue added

At the same time, the viscosity of the blood separation gel is quite high. If the operation is not careful, the glue thread will stick to the inner wall of the test tube, which will affect the measurement of blood.

[0003] At present, domestic blood separation glue filling machines ignore the influence of glue thread on the quality of blood collection tubes, resulting in unqualified products in the production process, which increases production costs and has a negative impact on users

Foreign blood separation gel filling machines are expensive, and domestic manufacturers cannot afford them
