Description

Technical Field

[0001] The utility model relates to a blood gas specimen temperature control device. Background Art

[0002] After the blood gas sample is collected, the syringe used to extract blood gas needs to be cooled so that it is at a low temperature for transportation in order to avoid affecting the blood gas values.

[0003] In the current prior art, the temperature of blood gas specimens is controlled by ice packs. Since the blood gas syringe is round, the ice pack freezes into blocks after being frozen. Therefore, the circumference of the syringe cannot be wrapped during the temperature control of the blood gas syringe, and the contact effect with the circumference of the syringe is poor, and the fit is low, which leads to poor temperature control and cooling effect. Furthermore, the blood gas syringe is round, and when placed on the ice pack, it is easy to roll during transportation, which may affect the arterial oxygen consumption and further affect the final blood gas value.
