The conception, the specific structure and the technical effects of the present invention will be further described with reference to the accompanying drawings, so as to fully understand the objects, the features and the effects of the present invention.
As shown in fig. 1, the present embodiment includes a portable immunochromatographic test strip detection device, which includes a kit 20 and a pneumatic device 10 used in combination.
As shown in fig. 2, 3 and 4, a test paper 21 is provided inside the reagent cartridge 20. The test paper 21 is a portable immunochromatographic test paper in the prior art. The front surface of the reagent kit 20 is provided with a detection line observation window 22 and a quality control line observation window 23 corresponding to the detection line and the quality control line of the test paper 21. The inspection line observation window 22 and the quality control line observation window 23 are covered with transparent cover plates.
In addition, an annular protrusion structure 24 is provided on the front surface of the reagent cartridge 20 at a region corresponding to the sample pad of the test paper 21, and a ring of elastic sealing gasket 25 for contacting the skin is provided on the top surface of the annular protrusion structure 24. The middle part of the annular bulge structure 24 is provided with a pinhole 26. During sampling, the elastic sealing gasket 25 can be tightly attached to the skin of a user, so that the kit 20 can conveniently suck blood.
As shown in fig. 4 and 6, a sample chamber 27 is provided inside the reagent cartridge 20, and the sample chamber 27 is located behind the pinhole 26 and communicates with the pinhole 26. The sample pad of the test strip 21 extends to the interior of the sample chamber 27. A lancet 28 is inserted into the sample chamber 27 and is disposed opposite the needle hole 26. The rear end of the lancet 28 is connected to a piston 29, and the piston 29 is disposed in a cylinder 30. The air cylinder 30 is connected with an air source interface 31 on the back of the reagent box 20. The piston 29 is driven by the pneumatic device 10 to push the lancet 28 along the cylinder 30 to puncture the skin and retract after the puncture is completed.
An air suction port 32 is formed on the inner wall of the sample chamber 27, and the air suction port 32 is connected to an air suction port 33 on the back of the reagent cartridge 20 through a pipeline. The air bleed port 33 is adapted to be connected to the pneumatic device 10 for drawing air after the lancet 28 pierces the skin, thereby creating a negative pressure in the sample chamber 27 to draw a sample of blood from the skin.
A diluent inlet 34 is formed in the inner wall of the sample chamber 27, and the diluent inlet 34 is communicated with a diluent container 35 inside the kit 20 through a pipeline; the diluent container 35 is also in communication with the first gas inlet 36 via a conduit. A sealing sheet 37 is bonded to the diluent inlet 34. In the case where the sample chamber 27 contains a blood sample, the pneumatic device 10 inflates the diluent container 35 through the first air inlet 36, so that the diluent breaks the sealing sheet 37 and enters the sample chamber 27 to be mixed with the blood sample.
In this embodiment, the first air inlet 36 and the air suction port 33 are integrally formed on the strip-shaped protrusion on the back surface of the reagent cartridge 20. The air source port 31 is arranged on a circular projection at the center of the back of the reagent kit 20. This arrangement avoids incorrect assembly of the pneumatic device 10 with the cartridge 20. The front face of the housing of the pneumatic device 10 is provided with a recessed portion adapted to the bar-shaped protrusion and the circular protrusion.
As shown in fig. 4 and 7, a pneumatic module and a control module are provided in the pneumatic device 10. The front face of the pneumatic device 10 is provided with interfaces respectively matched with the air source interface 31, the first air inlet 36 and the air suction interface 33 and respectively connected with the pneumatic device.
A control module for controlling the pneumatic module, the control module configured to: controlling the pneumatic module to drive the piston 29 to move in the cylinder 30 to drive the blood taking needle to pierce the skin; controlling the pneumatic module to pump air through the pumping port 32 so that the blood sample flows from the needle hole 26 into the sample chamber 27; and controls the pneumatic module to inflate the diluent container 35 so that the diluent breaks the sealing sheet 37 and enters the sample chamber 27 to be mixed with the blood sample.
In some embodiments, the pneumatic module includes three air pumps for connecting to the first air inlet 36, the suction port 33, and the air supply port 31, respectively. In other embodiments, the pneumatic module comprises an air pump, a plurality of electrically controlled valves and pipelines; the pipeline is provided with interfaces which are respectively connected with the first air inlet 36, the air suction interface 33 and the air source interface 31; the control end of each electric control valve is electrically connected with the control module. The control module realizes the functions by controlling the electric control valve and the air pump. In this embodiment, the air pump is a small-sized plunger pump, has two working modes of air suction and air inflation, and can be switched under the control of the control module. It is known in the art to combine a conduit with an electrically controlled valve to control the direction of airflow at a particular port in accordance with a predetermined sequence.
In this embodiment, the pneumatic module only inflates or deflates any one of the first air inlet 36, the air bleeding interface 33 and the air source interface 31 at the same time, and the control module controls the pneumatic module to control each interface of the reagent kit 20 according to a predetermined time sequence. The pneumatic device 10 is also provided with a battery inside, and an indicator light and/or a switch can be arranged on the shell of the pneumatic device 10.
When the portable immunochromatographic test strip detection device of the present embodiment is used, the back surface of the reagent kit 20 is attached to the front surface of the pneumatic device 10; the annular raised structure 24 on the front of the kit 20 is directed towards the skin of the user, preferably the fingertips. During sampling, the reagent vessel 20 is held against the user by pressing the pneumatic device 10 on the back of the reagent vessel 20, and the switch is then opened. The pneumatic module inflates the air cylinder 30 under the control of the control module, so that the piston 29 moves towards the front direction of the reagent kit 20 and pushes the blood taking needle 28 to pierce the skin of the user (as shown in fig. 5); subsequently, the pneumatic module draws air from the cylinder 30, so that the piston 29 draws the lancet 28 back inside the reagent vessel 20 (as shown in fig. 4). After the blood collection is completed, the control module controls the pneumatic module to suck air through the air suction port 32, so that negative pressure is formed in the sample chamber 27, and the blood sample flows into the sample chamber 27 from the needle hole 26. After the blood is drawn, the control module controls the pneumatic module to inflate the diluent container 35, so that the diluent breaks the sealing sheet 37 and enters the sample chamber 27 to be mixed with the blood sample. After the mixing is completed, the liquid permeates into the main body of the test paper along the sample pad of the test paper 21 and permeates into the quality control line and the detection line of the test paper, thereby realizing the detection of the blood sample.
The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the teachings of the present invention without undue experimentation. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
