Disposable hemostix

Abstract

The invention discloses a disposable hemostix. The disposable hemostix comprises a blood collection unit, a collection part is arranged at one end of the blood collection unit, a blood collection opening is formed in the collection part, a blood collection channel and a blood collection part are arranged in the blood collection unit, one end of the blood collection channel is communicated with the blood collection opening, the other end of the blood collection channel is communicated with the blood collection part, and blood enters the blood collection unit through the blood collection opening. The blood is collected by the blood collection part through the blood collection channel, a ventilation structure is arranged on the blood collection unit, and the ventilation structure is communicated with the blood collection part so as to promote the blood in the blood collection part to be dry. According to the disposable hemostix, quantitative blood sampling can be achieved, the blood sampling process is convenient to operate and control, storage and transportation are convenient, a blood sample is not prone to being polluted, the blood sampling unit is damaged by the breaking position when the blood collecting part is taken out, the blood sampling unit cannot be recovered, the blood sample can be prevented from being tampered before detection, and safety and accuracy of the blood sample are guaranteed.

Description

technical field [0001] The invention relates to the field of biochemical detection, in particular to a disposable blood sampling device. Background technique [0002] There are three kinds of blood sampling methods commonly used, and a kind of is venous blood sampling method, and a kind of is peripheral blood sampling method, and a kind of is arterial blood sampling method. Venous blood collection is the most widely used type of blood collection. Most clinical tests require venous blood collection, such as routine blood tests and various biochemical tests, including liver function, kidney function, and blood lipids. Most serological tests also require venous blood sampling, because the location of the vein is superficial and has little effect on changes in blood components, so venous blood sampling is generally used. Peripheral blood collection method is less used because peripheral blood is easily mixed into interstitial fluid when squeezed, and can be applied to various b...

Problems solved by technology

The disadvantage of this blood sample collection method is that it is difficult for the operator to control the amount of blood collected. If the blood volume is too small, the blood sample formed on the filter paper will be difficult to meet the detection requirements, which will affect the accuracy of the test results. If the blood volume is too large, it will Affects the speed of blood drying, causing the blood of the tested person to be wasted, which is very inconvenient to operate, and it is difficult to achieve quantitative blood collection

Since human hands are easy to come into contact with the filter paper during the blood collection process, the risk of contamination of the blood sample due to accidental contact is increased, thereby affecting the accuracy of the test result; The possibility of contact, creating a safety hazard

[0004] In addition, the above-mentioned blood samples formed directly by filter paper are not only inconvenient to transport and store, but also are prone to be tampered with or contaminated during the process of transport and store.
