Problems solved by technology

[0004] Existing detection of blood coagulation time adopts the method of detecting the change of the optical properties (degree of light transmission) of the mixture of plasma and reagent, or the method of using the change of magnetic property, and the test and analysis instrument based on these methods. The detection method is not intuitive enough, and the detection equipment is relatively complicated, the detection equipment is expensive, and the detection cost is also high. At the same time, the monitoring accuracy is often not satisfactory due to equipment or environmental factors.

Embodiment 1

[0043] Example 1 Portable blood coagulation test card -- dual card

[0044] Such as Figure 1 to Figure 4 As shown, this embodiment provides a portable blood coagulation detection card - a dual card.

[0045] The specific instructions are as follows:

[0046] figure 1 It is a schematic diagram of the overall structure of the portable blood coagulation detection card of the present invention - the dual card. The portable blood coagulation detection card of the present invention, duplex card, comprises: a bottom layer 101 printed with detection electrodes, a middle layer 102 through which the blood sample flows, and an upper layer 103 through which the blood sample siphons.

[0047] The upper layer 103 of the blood sample siphon, the middle layer 102 through which the blood sample flows, and the bottom layer 101 printed with detection electrodes are pasted in sequence; specifically, the middle layer 102 is a medical-grade double-sided tape with a thickness of 0.015-0.5 mm, T...

Embodiment 2

[0074] Example 2 Portable blood coagulation detection card--triple card

[0075] Such as Figure 6-Figure 9 As shown, this embodiment provides a portable blood coagulation detection card - triple card.

[0076] The specific instructions are as follows:

[0077] Figure 6 It is a schematic diagram of the overall structure of the portable blood coagulation detection card of the present invention - triple card. The portable blood coagulation detection card of the present invention, the triple card, comprises: a bottom layer 101 printed with detection electrodes, a middle layer 102 through which the blood sample flows, and an upper layer 103 through which the blood sample siphons.

[0078] The upper layer 103 of the blood sample siphon, the middle layer 102 through which the blood sample flows, and the bottom layer 101 printed with detection electrodes are pasted in sequence; specifically, the middle layer 102 is a medical-grade double-sided tape with a thickness of 0.015-0.5 m...

Embodiment 3

[0096] Embodiment 3 The instrument of one of the most preferred examples of the present invention

[0097] Figure 10 It is a schematic diagram of the instrument of one of the most preferred examples of the present invention.

[0098] In this embodiment, there is a machine shell and a liquid crystal display to display the test results for the user, and some simple instrument operation options can be performed according to the prompts on the display.

[0099] On the side of the picture are the external Code code chip device and the switch button. The code code chip encodes the built-in algorithm to convert it into content value, ratio and INR value, etc. There is a USB interface (not shown in the figure) on the top of the instrument, which can be connected to a USB data cable to export data and charge the instrument. The "①" button in the figure is used to turn on and off the machine operation "①" on the display screen, the "left" and "right" buttons are used to select menu o...

Abstract

The invention discloses a portable blood coagulation test card. The portable blood coagulation test card comprises a bottom layer with a printed detection electrode, a middle layer through which a blood sample flows, and an upper layer for blood siphon, wherein the upper layer, the middle layer and the bottom layer are stuck in sequence, the upper layer is provided with a sample add area for adding a blood sample, the middle layer is provided with at least two test channels, one end of the test channel is communicated with the sample add area, the other end of the test channel is provided witha test area, one test channel is a delay channel, an obstacle is arranged in the middle in the delay channel, the end part of the test area is provided with an air hole communicated with the upper layer, the inner side wall of the bottom layer is provided with an electrode conduction area connected with the test area, and the end part of the electrode conduction area is inserted into a test hostto be detected. The portable blood coagulation test card can deliver a detection result within one or two minutes through a drop of fingertip blood or venous whole blood only, thereby being convenientto test, being accurate and sensitive, being portable, and being convenient and flexible to use.

Description

technical field [0001] The invention relates to a portable blood coagulation detection card, which belongs to the field of preparation of portable blood coagulation detection cards. Background technique [0002] The process of blood coagulation is referred to as coagulation, which is divided into physiological coagulation and pathological coagulation. If there is a wound in the body, physiological coagulation will occur, and the coagulation pathway will form a blood clot to protect the blood loss in the body, which is an internal protection mechanism; while cerebral thrombosis, pulmonary embolism, deep vein thrombosis and disseminated intravascular coagulation (DIC ) and so on belong to pathological coagulation, which are caused by coagulation factors in the body. The coagulation process is a process in which a series of coagulation factors are successively enzymatically activated (commonly known as intrinsic and extrinsic coagulation pathways in academic circles), activati...
