Abstract
The utility model relates to a kind of test tube, particularly relates to a kind of double-layer vacuum test tube.A kind of double-layer vacuum test tube, comprise outer test tube and cap test tube, inside described outer test tube, middle is provided with interior test tube, the hypomere of interior test tube is provided with conical bottom, outer surface one circle of outer test tube scribbles thermal protective coating, thermal protective coating is evenly distributed with one and arranges window in the middle of its outer test tube, window and locate visible interior test tube, the dead slot depositing ice cube is formed between interior test tube and outer test tube, described cap test tube comprises outer cap test tube and interior cap test tube, and outer cap test tube and interior cap test tube mate mutually with the head of outer test tube and interior test tube respectively.By the slow melting process of scientific and technological ice; with the protection of thermal protective coating, can ensure when environment temperature is too high (as summer), effective low-temperature protection can be carried out to sample; to the time sent between laboratory after prolongation collection of specimens, ensure the quality before analyzing specimen.
Description
Technical field
The utility model relates to a kind of test tube, particularly relates to a kind of double-layer vacuum test tube.
Background technology
According to the general requirement of Lab of Clinical Medicine to quality control before sample analysis, for avoiding after collection of specimens as far as possible and before censorship, and in censorship process environment temperature, standing time etc. adverse effect that factor may cause testing result (as: blood sugar test sample is when environment temperature is higher and standing time is longer, red blood cell can a large amount of consumption of glucose, causes blood glucose test results more on the low side than actual value.), this just requires that clinical nursing staff is at conventional Christmas blood samples of patients sample, after the humoral specimen such as blood of especially inpatient, immediately sample should be sent to laboratory and carry out serum separation or upper machine testing.But in actual mechanical process, often due to reasons such as patient are more, medical personnel are limited, after nurse usually has to all patient's samples to gather one by one, more centralized and unified censorship, and do not reach the requirement of censorship immediately.When summer, room temperature was higher, this will certainly cause the impact on quality before patient's analyzing specimen, causes detecting data exception, thus misleads clinic diagnosis, causes unnecessary trouble.Therefore, we have designed and produced a kind of double-layer heat insulation vacuum test tube, to facilitate the quality control before analyzing specimen.
Summary of the invention
The purpose of this utility model is: the deficiency existed for prior art, provides a kind of easy to operate double-layer vacuum test tube.
For realizing the object of the utility model, be achieved by the following technical solutions:
A kind of double-layer vacuum test tube, comprise outer test tube and cap test tube, inside described outer test tube, middle is provided with interior test tube, the hypomere of interior test tube is provided with conical bottom, outer surface one circle of outer test tube scribbles thermal protective coating, thermal protective coating is evenly distributed with one and arranges window in the middle of its outer test tube, window and locate visible interior test tube, the dead slot depositing ice cube is formed between interior test tube and outer test tube, described cap test tube comprises outer cap test tube and interior cap test tube, and outer cap test tube and interior cap test tube mate mutually with the head of outer test tube and interior test tube respectively.
As preferably, described window on be equipped with graduated scale, the graduated scale between upper dropping window is mutually corresponding.
Compared with prior art; the beneficial effects of the utility model are: by the slow melting process of scientific and technological ice; with the protection of thermal protective coating; can ensure when environment temperature is too high (as summer); effective low-temperature protection can be carried out to sample; to the time sent between laboratory after prolongation collection of specimens, ensure the quality before analyzing specimen.

Fig. 2 is the structural representation of test tube 3 in the utility model.
Detailed description of the invention
1-2 makes a detailed explanation detailed description of the invention of the present utility model with reference to the accompanying drawings below.
Embodiment 1
A kind of double-layer vacuum test tube, comprise outer test tube 1 and cap test tube 2, inside described outer test tube 1, middle is provided with interior test tube 3, the hypomere of interior test tube 3 is provided with conical bottom 4, outer surface one circle of outer test tube 1 scribbles thermal protective coating 5, thermal protective coating 5 is evenly distributed with one and arranges window 6 in the middle of its outer test tube 1, window 6 places visible in test tube 3, the dead slot 7 depositing ice cube is formed between interior test tube 3 and outer test tube 1, described cap test tube 2 comprises outer cap test tube 8 and interior cap test tube 9, outer cap test tube 8 and interior cap test tube 9 mate mutually with the head of outer test tube 1 and interior test tube 3 respectively, described windowing on 6 is equipped with graduated scale 10, graduated scale 10 between upper dropping window 6 is mutually corresponding, the ice cube filled in this test tube is defined as scientific and technological ice.Owing to being vacuum test tube, so be direct airtight connection.
Before preparation blood sampling, first this test tube is positioned in refrigerator freezing, after scientific and technological ice solidifies, takes out and use.In using, first cap test tube 2 is opened, in interior test tube 3, load the samples such as blood, fasten cap test tube 2, ensure that it is airtight.Thermal protective coating 5 does not reduce rapidly for the protection of temperature, but mostly be colored coating due to thermal protective coating 5, so design is windowed and 6 can be seen situation in interior test tube 3, and is furnished with graduated scale 10 and can knows and know amount of capacity.The below conical bottom 4 of interior test tube 3 is in order to specimen centrifuge; because precipitation can be there is in material; so all can be deposited to bottom; and conical bottom 4 ensures the scientific and technological ice amount adding outside one circle; sample is after bottom precipitation, and the scientific and technological ice in outside ensures more obvious, can carry out effective low-temperature protection to sample; to the time sent between laboratory after prolongation collection of specimens, ensure the quality before analyzing specimen.
Claims (2)
1. a double-layer vacuum test tube, comprise outer test tube and cap test tube, it is characterized in that, inside described outer test tube, middle is provided with interior test tube, the hypomere of interior test tube is provided with conical bottom, outer surface one circle of outer test tube scribbles thermal protective coating, thermal protective coating is evenly distributed with one and arranges window in the middle of its outer test tube, window and locate visible interior test tube, the dead slot depositing ice cube is formed between interior test tube and outer test tube, described cap test tube comprises outer cap test tube and interior cap test tube, and outer cap test tube and interior cap test tube mate mutually with the head of outer test tube and interior test tube respectively.
