Description
Technical Field
The invention relates to a capillary tube for storing and adding a sample stabilizer, in particular to the technical field of medicine.
Background
The blood concentration detection is guided by the pharmacokinetic principle, and the concentration of the medicine in blood is analyzed and measured to evaluate the curative effect or determine the administration scheme, so that the administration scheme is individualized, the treatment level of the medicine is improved, and the clinical safe, effective and reasonable administration is achieved. Although blood is not a major metabolic organ of the human body, a small amount of enzymes is present in blood and can decompose specific several drugs such as carbapenems and 5-fluorouracil. Because the clinical blood sample can be centrifuged and frozen for storage after blood drawing is difficult to realize, in order to ensure the stability of the drug in the processes of transportation and detection, metabolic enzymes need to be inactivated, and a common method is to add a stabilizer, such as carbapenems, N-methylmorpholine and 5-fluorouracil, into uracil, so that the clinical blood sample is convenient to collect and store in scientific research samples.
In clinical use, a stabilizing agent is generally required to be prepared into a concentrated solution, a certain volume of the concentrated solution is absorbed by using a pipette gun and then the concentrated solution is added into a blood sample, so that a pipette gun is required to be prepared for each blood sampling point, the pipette gun belongs to a precise instrument, for example, patent CN 208894255U discloses a portable pipette gun and a pipette head integrated box, a pipette gun frame and a pipette head integrated box are integrated, the portable pipette gun and the pipette head integrated box are convenient to carry and use, an elastic material is adopted for a pipette gun fixing device, the purpose of protecting the pipette gun can be achieved, but the pipette gun belongs to the precise instrument, so that the price is high, and a blood sampling person can use the pipette gun by a professional trained worker, so that the use cost is greatly increased, and human resources are wasted.
At present, a common storage agent for stabilizing samples in China is stored according to the characteristic that the sample is easy to dissolve in water or an organic solvent according to the dissolution characteristic, but bacteria can grow in an aqueous solution after the aqueous solution is placed for a long time, and the concentration of the organic solvent can be changed due to volatilization of the solvent after the organic solvent is placed for a long time, so that the use of the stabilizing agent is influenced, and the storage of the sample stabilizing agent is particularly important.
When the sample stabilizer is used, the blood sampling cap needs to be opened, so that operators are easily infected by pathogenic microorganisms in the blood sampling cap, and the physical conditions of the operators are damaged.
In summary, the storage mode and the transfer mode of the sample stabilizer in China at present have a series of defects, such as: at present, China has high use cost in a sample stabilizer transferring mode, human resources are wasted, and two lines of defects of the sample stabilizer are easy to exist in storage, a water solution can breed bacteria after being placed for a long time, two organic solvents volatilize due to the solvents after being placed for a long time, concentration can be changed, and when the sample stabilizer is used, a blood sampling cap needs to be opened, an operator is easily infected by pathogenic microorganisms inside, and the problems of harm and the like to the physical condition of the operator are caused. Therefore, the invention of a capillary tube which is convenient to carry, store, move and take and integrally stores and adds a sample stabilizer is urgently needed.
