Description
Technical Field
The utility model relates to medical supplies, in particular to a temporary blood storage and transfer device for virus antibody detection.
Background
Typically, the virus-neutralizing antibody assay is performed using serum, plasma or whole blood, and venous blood. The conventional steps are as follows: (1) blood was drawn using vacuum negative pressure tube (5ml) EDTA tube; (2) opening a pipette or a suction tube for the blood collection tube to absorb a small amount (3 drops); (3) the sample is added to the test card.
The conventional procedure has the following problems: (1) the blood sampling tube used in the detection is 5ml, and the blood volume used in the reagent operation is not more than 3 drops, thereby causing the waste of blood. (2) The cover is opened in the transferring process, and the step of imbibing (blood) is relatively troublesome.
Aiming at the problems, the utility model is mainly used for solving two main problems of blood waste caused by large blood taking amount in virus neutralization antibody detection and complex and time-consuming blood transportation.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a temporary blood storage and transfer device for virus antibody detection, which is mainly used for solving two main problems of blood waste and complex and time-consuming blood transfer caused by large blood taking amount in virus neutralization antibody detection.
In order to achieve the purpose, the utility model provides the following technical scheme:
a temporary blood transfer device for viral antibody detection, comprising: the pipe comprises a pipe body and a pipe opening plug covering the pipe opening of the pipe body; the tube cavity of the tube body is a negative pressure vacuum cavity; the center of the pipe orifice plug is of a rubber structure which can be punctured; the end, far away from the pipe orifice plug, of the pipe body is provided with an extending part which is communicated with the pipe body.
Further, the extension is of a tapered configuration.
Further, the extension is 5 mm in length.
Further, the length of the pipe body is 20 millimeters.
Furthermore, a small salient point is arranged on the outer side of the pipe orifice plug.
Compared with the prior art, the utility model has the beneficial effects that: in the using process, one end of the blood taking needle is connected with a human body vein, and the other end of the blood taking needle pierces the rubber structure and is connected into the tube body; stopping the blood draw when the volume of the blood exceeds about 2/3% of the volume of the tube body, and removing the blood drawing needle; preparing a detection card and diluent required by detection; the extension was cut off approximately 1/3 in length, and the tube was gently squeezed to allow blood to exit and drip into the test card. The device simple structure can reduce blood waste, and the process of blood transportation can be simplified to the small.
Drawings
FIG. 1 is a schematic view of a temporary blood transfer device for virus antibody detection.
Detailed Description
In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a temporary blood transport device for virus antibody detection includes: comprises a tube body 101 and a tube opening plug 102 covering the tube opening of the tube body 101; the lumen 103 of the tube 101 is a negative pressure vacuum lumen. The center of the pipe orifice plug 102 is a rubber structure 104 which can be punctured; the end of the pipe body 101 away from the pipe opening plug 102 has an extension 105, and the extension 105 is communicated with the pipe body 101.
In the embodiment of the present invention, the extension portion 105 has a tapered structure, and one end of the extension portion is larger and the other end is smaller when the extension portion is communicated with the tube 101. In other embodiments, the extension 105 may also be a cylinder structure.
In the using process, one end of the blood taking needle is connected with a human body vein, and the other end of the blood taking needle pierces the rubber structure 104 and is connected into the tube body 101; stopping the blood draw when the volume of blood exceeds about 2/3% of the volume of the tube 101, and removing the blood drawing needle; preparing a detection card and diluent required by detection; the extension 105 is reduced by about 1/3, and the tube 101 is gently squeezed to allow blood to flow out and drip into the test card. Therefore, the two main problems of blood waste caused by large blood taking amount in virus neutralization antibody detection and complex and time-consuming blood transfer can be solved.
The extension 105 has a length d1 of 5 mm. The length d2 of the tube 101 is 20 mm. Extension 105 with the length of body 101 all is according to the best length that obtains after the clinical trial, so set up, can save the material by furthest, simultaneously, also can realize the function that detects better.
The pipe body 101 may be made of a common PET material or a PP material. Or, other plastic materials with better flexibility can be adopted, so that the extrusion is convenient. The outside of the tube opening plug 102 is provided with small protruding points 106, because the blood temporary storage transfer device has a small volume, and is easy to slip and drop by hand when being taken, and therefore the effective protruding points 106 arranged on the outside of the tube opening plug 102 increase friction force. The device can be used for virus antibody detection, such as new coronavirus antibody detection.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art of automotive wire fixing technology will be able to cover the technical scope of the present invention, and equivalent alternatives or modifications according to the technical solution of the present invention and the inventive concept thereof.
