Description
Technical Field
The utility model relates to the technical field of POCT (point of care testing), in particular to a sampling dropper used on a whole blood POCT reagent card strip seat.
Background
Point-of-care testing (POCT), which refers to clinical and bedside tests performed beside a patient, makes the test easier. The whole blood POCT test object is whole blood. When a whole blood sample is dispensed to a whole blood POCT reagent card holder in a whole blood POCT kit, a pipette or other instrument is required. In clinical POCT examination of whole blood, even if the reagent is in the form of a card strip, a set of pipettors is required to split the whole blood sample. In addition, in order to reduce damage to blood cells when processing whole blood samples, care must be taken to dispense using a wide-suction pipette.
Disclosure of Invention
The utility model aims to provide a sampling dropper used on a whole blood POCT reagent card strip seat, which solves the defects in the prior art.
The utility model adopts the following technical scheme:
a sampling dropper used on a whole blood POCT reagent card strip seat comprises a suction nozzle, a dropper body and a compressible air bag;
the suction nozzle is arranged at the front end of the dropper body, is communicated with the dropper body, and the compressible air bag is arranged at the rear end of the dropper body, is communicated with the dropper body, and the horizontal central lines of the suction nozzle, the dropper body and the compressible air bag are on the same straight line;
the inner diameter of the suction nozzle is more than 1mm, two walls at the near front end of the dropper body are pressed inwards to seal to form an elliptical or circular sealing part, the horizontal center line of the sealing part is arranged on the horizontal center lines of the suction nozzle, the dropper body and the compressible air bag, the width of the sealing part is 10-95% of the inner width of the dropper body and is larger than the inner diameter of the suction nozzle, and the distance between the front end of the sealing part and the rear end of the suction nozzle is 3-30% of the length of the suction nozzle;
the outer bottom of the dropper body is provided with a strippable glue layer.
Further, the inner diameter of the suction nozzle is 1-3.5 mm.
Further, the sampling dropper is made of plastic materials.
The utility model has the beneficial effects that:
the utility model realizes that the sampling dropper for sub-packaging whole blood samples is adhered to the whole blood POCT reagent card strip seat without preparing a set of liquid transfer device.
According to the utility model, the inner diameter of the suction nozzle of the sampling dropper is widened (the inner diameter of the suction nozzle of a general liquid-transfering device is smaller than 1 mm), so that on one hand, whole blood samples are easily sucked, on the other hand, the damage to blood cells is reduced, and meanwhile, a part of the dropper body of the sampling dropper is pressed and sealed to form an elliptical or circular sealing part, so that on the one hand, physical damage to the blood cells caused by rapid and rapid suction is prevented, and on the other hand, unnecessary large-scale suction is avoided.
The utility model has simple structure, low cost, easy operation and suitability for popularization.

FIG. 1 is a schematic diagram of the structure of the present utility model.
Fig. 2 is a schematic diagram of the direction and distance indication of the present utility model.
Fig. 3 is a schematic drawing of a whole blood sample drawn by the sampling dropper (a is a schematic drawing drawn without a sealing part, and b is a schematic drawing drawn with a sealing part).
Whole blood POCT reagent card holder 1, reagent cup 101, sample cup 102, sampling dropper 2, suction nozzle 201, dropper body 202, compressible air bag 203, sealing part 204, peelable adhesive layer 3.
Detailed Description
The utility model will be further explained with reference to examples and figures. The following examples are only illustrative of the present utility model and are not intended to limit the scope of the utility model.
A sampling dropper 2 for use on a whole blood POCT reagent cartridge 1 (whole blood POCT reagent cartridge 1 comprising a reagent cup 101 and a sample cup 102), as shown in fig. 1 and 2, comprises a suction nozzle 201, a dropper body 202, and a compressible bladder 203.
The suction nozzle 201 is arranged at the front end of the dropper body 202 and is communicated with the dropper body 202, the compressible air bag 203 is arranged at the rear end of the dropper body 202 and is communicated with the dropper body 202, and the horizontal central lines of the suction nozzle 201, the dropper body 202 and the compressible air bag 203 are on the same straight line.
The internal diameter c of the suction nozzle 201 is 1mm or more, preferably 1 to 3.5mm. The two walls near the front end of the dropper body 202 are pressed inwards to seal to form an elliptical or circular sealing part 204 (the sealing part can be stuck together after being melted by heat, and the other parts can be shaped by heating), the horizontal center line of the sealing part 204 is on the horizontal center lines of the suction nozzle 201, the dropper body 202 and the compressible air bag 203, the width a of the sealing part 204 is 10-95% of the inner width b of the dropper body 202 and is larger than the inner diameter c of the suction nozzle 201, and the distance d between the front end of the sealing part 204 and the rear end of the suction nozzle 201 is 3-30% of the length e of the suction nozzle 201.
The outer bottom of the dropper body 202 is provided with a strippable glue layer 3, so that the sampling dropper 2 can be conveniently taken and placed.
The sampling dropper 2 is made of plastic.
The utility model widens the inner diameter of the suction nozzle 201 of the sampling dropper 2, on the one hand, the whole blood sample is easy to suck, and on the other hand, the damage to blood cells is reduced, but the inner diameter of the suction nozzle 201 is widened, the liquid sucking speed is increased, the physical damage to blood cells is caused, and an unnecessarily large amount of sucking is easy to generate (a in fig. 3), therefore, the utility model presses and seals a part of the dropper body 202 of the sampling dropper 2 to form an elliptical or circular sealing part 204 so as to buffer the sucking speed, on the one hand, the physical damage to blood cells caused by rapid and rapid sucking can be prevented, and on the other hand, the unnecessarily large amount of sucking can be avoided (b in fig. 3).
