Abstract

The invention discloses a detection kit, wherein a kit body is provided with a liquid absorption pad storage cavity, a liquid absorption pad is arranged in the liquid absorption pad storage cavity, the liquid absorption pad storage cavity and the inner cavity are provided with a communication port, and the side wall of the liquid absorption pad storage cavity is provided with a first exhaust hole communicated with the outside of the kit body. According to the detection kit, the first exhaust hole which is formed in the side wall of the storage cavity of the liquid absorption pad and is communicated with the outside of the kit body is used for enabling the air pressure in the storage cavity of the liquid absorption pad to be kept balanced due to the exhaust hole when the liquid absorption pad is used for recycling waste liquid after detection is finished, so that the waste liquid is successfully recycled by the liquid absorption pad.

Description

Detection kit Technical Field The invention belongs to the field of biological sample detection, and particularly relates to a detection kit for detection. Background Medical in vitro diagnostics plays a fairly reuse role in the medical industry today, which can qualitatively or quantitatively measure the change of various biological indicators in human fluids to provide consultation of disease diagnosis or therapeutic indicators, e.g. the detection of glycosylated hemoglobin (HbA 1 c) in blood is crucial for the diagnosis and control of diabetes. Glycosylated hemoglobin is the product of the combination of hemoglobin in red blood cells in human blood with blood glucose, and when the concentration of glucose in the blood is high, the HbA1c content formed in the human body is also relatively high. The average life of red blood cells in a human body is 120 days, and the HbA1c content in blood remains relatively unchanged before the cells die, so that the glycosylated hemoglobin test can generally reflect the blood glucose control condition of a patient for approximately 8-12 weeks without being influenced by occasional blood glucose increase or decrease. There are a variety of detection kits in the prior art for detecting the concentration of an analyte. The detection kit as shown in WO2017005123A1, CN106124780A, etc. is provided with a reagent storage portion, a reagent release portion, a reaction portion, a detection region, a sampler, and a liquid absorption pad. The sampling rod is used for collecting liquid samples such as blood, urine and the like, and adding the liquid samples into the detection kit. After the detection is finished, the liquid absorption pad recovers the liquid (waste liquid) remained in the detection kit after the detection reaction, so that the liquid is prevented from leaking to the outer head of the detection kit to pollute the environment. However, the liquid absorbing pad is often arranged at one corner of the inner cavity of the kit, and when the liquid absorbing pad is used for recycling waste liquid, the waste liquid is influenced because the gas (air) in the liquid absorbing pad and the nearby inner cavity is not smoothly exhausted. Disclosure of Invention The invention provides a detection kit, which aims at the technical problems existing in the prior art when the detection kit uses a liquid absorption pad to absorb waste liquid after detection is completed, and the detection kit is provided with an exhaust hole, so that the exhaust can be carried out to balance air pressure when the liquid absorption pad recovers the waste liquid, and the waste liquid can be recovered smoothly. The detection kit comprises a kit body, wherein an inner cavity is formed in the kit body, a liquid absorption pad storage cavity is further formed in the kit body, a liquid absorption pad is arranged in the liquid absorption pad storage cavity, the liquid absorption pad storage cavity and the inner cavity are provided with communication ports, and a first exhaust hole communicated with the outside of the kit body is formed in the side wall of the liquid absorption pad storage cavity. The first exhaust hole may be formed in any side wall of the storage chamber of the liquid absorbing pad, so long as the liquid absorbing pad is communicated with the outside, the exhaust function is realized when the liquid absorbing pad is used for recycling waste liquid, and the air pressure balance in the storage chamber of the liquid absorbing pad is maintained. When the exhaust hole and the communication port are arranged on the same side of the liquid absorption pad storage cavity, a fine gap exists between the liquid absorption pad and the side wall of the liquid absorption pad storage cavity, and liquid extends along the gap due to capillary phenomenon, so that waste liquid which is not timely absorbed by the liquid absorption pad flows on the side edge of the liquid absorption pad and directly seeps out of the detection kit through the exhaust hole along the gap between the liquid absorption pad and the cavity wall, and the external space is polluted. In order to better avoid the exudation of the waste liquid to the outside of the detection kit, the invention is further improved by a method for realizing the recovery of the solution by utilizing reasonable channel design, and the exudation of the solution is avoided. Preferably, the first exhaust hole is arranged at a position which is not on the same side of the storage cavity of the liquid absorption pad as the position at which the communication port is arranged. The specific setting position of the first vent hole is at the position which is set up with the communication port is not at the same side of the liquid absorption pad storage cavity, so that the problem that waste liquid generated by the fact that the vent hole and the communication port are set up at the same side of the liquid absorption pad storage cavity directly flows along the side edge of
