Portable blood infectious disease fast joint inspection device

Abstract

The invention discloses a portable rapid combined detection device of the blood borne infections, including a sample suction head (1) and a detection tube (2) which is connected at the back end of the sample suction head (1). The front end of the sample suction head (1) is provided with a thin tube suction mouth (12), the suction mouth (12) is provided with a sample suction port (13) for sample suction, the front end of the suction mouth (12) can be sheathed with a rubber protecting cap (14), an inner cavity (17) of the sample suction head can be respectively filled with sample filter materials (3) and sample water absorbent materials (4) from the front to the back, the interior of the detection tube (2) is provided with a test paper fixed column (5), an HBsAg detection test paper strip, a HCV antibody detection test paper strip, a HIV antibody detection test paper strip and a syphilis antibody detection test paper strip are fixedly arranged on the test paper fixed column (5), and thetail end of the detection tube is provided with a sealing cover (7) to seal the waste after detection in the detection tube (2), so as to prevent leakage. All the detection test paper strips (6) which are sealed and fixed in the device are carried out the one-time sample suction and the detection with the same background, the invention can carry out the combined detection of HBsAg, HCV antibody, HIV antibody and syphilis antibody in the sample at one time simultaneously within a plurality of minutes by using the naked eye, the detection of the four indicators which are related to the transfusion infection becomes more simple, safe and rapid; furthermore, the cross-interference can be avoided, the waste after detection is still sealed in the detection tube, so the invention is conductive to the avoidance of spread of pathogens and iatrogenic infection, and is more conductive to the environmentally protective treatment of the waste.

Description

technical field [0001] The invention relates to a medical device and a sample detection test paper, in particular to a portable reaction device capable of simultaneously detecting multiple blood infectious disease pathogens at one time. Background technique [0002] Hepatitis B, hepatitis C, syphilis and AIDS are four common infectious diseases related to blood safety. The incidence of these four diseases in my country has accounted for nearly 30% of the total incidence of infectious diseases in recent years. People's lives have brought great harm. In order to prevent the threat of blood infectious diseases to blood safety, the Ministry of Health of my country stipulates that blood donors must check for hepatitis B virus surface antigen (HBsAg), hepatitis C virus antibody, HIV antibody and Treponema pallidum antibody. According to the statistics of the World Health Organization, an average of 8ml of blood per person in the world can meet the needs of clinical blood use. Acco...

Problems solved by technology

[0004] Chinese patent ZL.200420096377.3 and application number 200410080305.4 disclose a rapid diagnostic test tube for vacuum blood collection. Although the device can be used for joint inspection of several samples, it can also better solve the problems of iatrogenic infection and environmental pollution, but it has disadvantages Yes: (1) The structure of the device is complicated, the manufacturing cost is high, and it is difficult to popularize

(2) The scope of application is limited

The device is only suitable for health technicians to collect blood from the subject for on-site detection, but for some samples that have been collected and prepared in advance, such as collected and prepared blood, separated and prepared serum or plasma, etc. there is nothing you can do

(3) Vacuum test tube blood collection is far from being popularized in the majority of grassroots institutions and rural areas in my country, and accidents such as iatrogenic infection, pathogen dissemination, and environmental pollution often occur due to failure of blood collection.

In addition, Chinese patent application No. 200410099301.0 discloses a colloidal gold test strip that can jointly detect multiple pathogens, and Chinese patent application Nos. 02112230. Although these colloidal gold test strips and colloidal gold percolation devices can achieve various indicators in the joint inspection samples, there are still deficiencies: (1) the joint inspection indicators are all placed on a test paper, and each detection The cross-interference existing between

(2) Serum needs to be separated from the sample to be tested, which is not suitable for whole blood sample testing

Because the red blood cells in the whole blood can hinder the migration of the sample on the test strip, and the red color of the red blood cells also interferes with the appearance, observation and identification of the colloidal gold red band, and the separation of serum is not only time-consuming, but also requires certain equipment , reagents and conditions
