Background
Along with the improvement of society and the improvement of living standard of people, people pay more attention to the health of the people, early diagnosis of diseases and the like, so that more accurate and convenient diagnosis means are needed, especially for blood detection, the blood detection in the prior art mainly comprises the steps of collecting blood into a vacuum test tube, extracting the blood from the vacuum test tube by using a dropper and dripping the blood onto a blood detection test paper, and carrying out relevant analysis on the blood by using a detection instrument after detection reaction occurs on the detection test paper, so that the process operation is more complicated.
At present, the integrated blood sampling and analyzing device on the market is a ready-to-use blood detection test paper box with a patent number of CN201721417213.X, and comprises a box body and a test strip which is arranged in the box body and contains an anticoagulant, wherein a blood sampling hole which is communicated with the outside is formed in the box body, the blood sampling hole can be aligned to a skin puncturing position to suck blood, and the test strip can collect the blood through the blood sampling hole for detection; the test strip comprises a blood sampling section and a detection section which are mutually connected at the end parts, the anticoagulant is arranged on the blood sampling section, and blood at the blood sampling hole sequentially flows through the blood sampling section and the detection section. However, there are some problems that the operation is complicated, the operator drops blood on the test paper in addition to taking blood, the anticoagulant is put by himself, and the operator is hard to get on hand.
Disclosure of Invention
The scheme provides a blood sampling analysis integrated device for solve the too loaded down with trivial details problem of operation step.
In order to achieve the above purpose, the scheme provides an integrated blood sampling and analyzing device, which comprises a needle head, test paper, a push rod needle, a catheter, a vacuum box, a medicine hopper, a base and a push plate spring, wherein the base is provided with a blood taking port and a push rod port, one end of the push plate spring is fixed on the base, and the other end of the push plate spring is fixedly connected with the push plate; push rod needle contains clamp plate, single pole and dog, clamp plate and single pole board fixed connection, single pole and dog fixed connection, be equipped with the through-hole that allows the push pedal to pass through in the middle of the single pole, single pole and push rod mouth sliding connection, the dog bottom is provided with gets the blood needle, it sets up with the coaxial heart of base blood taking port to get the blood needle, vacuum box and base sliding connection, and vacuum box and push pedal are located same horizontal line, the vacuum box is provided with a airtight rubber mouth, pipe one end and base blood taking port phase-match, the other end and syringe needle intercommunication, the coaxial heart of rubber mouth of syringe needle and vacuum box sets up.
The principle of the scheme is as follows: the operator presses the push rod needle, the push rod needle punctures the skin, then the operator pulls out the push rod needle, the catheter contacts blood, and simultaneously the push plate spring moves the vacuum box to the fixed needle through the middle cavity of the push rod needle, and the needle is inserted into the vacuum box, so that the pressure intensity in the vacuum box is small, and suction force is generated. Blood is sucked into the catheter and enters the vacuum box, falls on the test paper, and after a period of time, the change on the test paper is watched, and whether the operator suffers from diseases is analyzed.
The beneficial effect of this scheme lies in: 1. compared with the prior blood sampling analysis device, the scheme simplifies the steps of originally drawing blood, dripping test paper and adding anticoagulant, and is more convenient and easy to operate because only one push rod needle is pressed. 2. Because the vacuum box is in a vacuum environment, blood is less prone to coagulation, and no external environmental pollution exists. 3.
