Disposable hard connecting band collection container and anti-freezing vacuum blood taking needle of bleeding opening

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a disposable hard connecting band collection container and an anti-freezing vacuum blood taking needle of a bleeding opening. The disposable hard connecting band collection container is formed in the following mode that: an anticoagulant coating layer is arranged on an inner cavity wall of a circular connector; one end of the connector is provided with a venous blood taking needle; the rear part of the connector is provided with a vacuum valve; the other end of the connector is provided with the blood collection sample bottle needle; the blood collection sample bottle needle is connected with a blood collection sample bottle cap; the blood collection sample bottle cap is connected with a rubber plug; the rubber plug is connected with a blood collection sample bottle; and one side on the blood collection sample bottle close to the blood collection sample bottle cap is provided with one secondary bleeding opening. The disposable hard connecting band collection container and the anti-freezing vacuum blood taking needle of the bleeding opening have the advantages that: the anticoagulant coating layer is added on the basis of the conventional hard connection type blood taking needle so that blood flowing out of a body can contact an anticoagulant; a blood sample is ensured to generate no cruor and hemolysis so as to ensure the accuracy of the test result; and the secondary bleeding opening is added so that a clinical inspector can flexibly control the blood dosage during the test to ensure repeated tests at any time or add new testing items.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to an anticoagulant vacuum blood collection needle for medical use with a disposable hard-bonded collection container and a bloodletting port. Background technique [0002] At present, the traditional hard-wired blood collection needles in my country have the following disadvantages: [0003] 1. Traditional hard-connected blood collection needles: Thrombosis and hemolysis are prone to occur in an instant during clinical blood collection, especially when patients with certain diseases (such as hyperlipidemia) draw blood, blood coagulation occurs when the blood flows out of the body, and thrombosis is easy Blockage of the blood collection needle affects the quality of the test. [0004] 2. The traditional hard-connected blood collection needle is not connected to the vacuum blood collection tube, and it needs to be connected by nurses and other medical personnel during the bl...

Problems solved by technology

[0003] 1. Traditional hard-connected blood collection needles: Thrombosis and hemolysis are prone to occur in an instant during clinical blood collection, especially when patients with certain diseases (such as hyperlipidemia) draw blood, blood coagulation occurs when the blood flows out of the body, and thrombosis is easy Blockage of blood collection needle affects the quality of inspection

[0004] 2. The traditional hard-connected blood collection needle is not connected to the vacuum blood collection tube, and it needs to be connected by nurses and other medical staff during the blood drawing operation.

The traditional design makes nurses and other medical staff increase the operation links when drawing blood; increases the probability of error; increases the workload; it is not suitable for a large number of fast and concentrated clinical blood drawing operations

[0005] 3. There is no anticoagulant in the traditional hard-connected blood collection needle, and the anticoagulant is contained in the vacuum blood collection tube, so after clinical blood drawing, it needs to be inverted and mixed immediately (in order to facilitate the better combination of blood and anticoagulant) 5-8 Second-rate

[0006] 4. Too many packaging materials are not conducive to environmental protection and reducing medical waste

[0007] 5. The price is high, increasing the cost of national medical insurance

[0008] 6. Traditional vacuum blood collection tubes do not have a second bloodletting port. When the blood sample in the entire blood collection tube is tested on the machine, the reading data may fail or the clinical laboratory personnel think it is necessary to repeat the test. At this time, because the detection machine probe enters the entire blood collection tube The blood sample of the whole tube will be polluted and deteriorated, and the blood of the patient needs to be drawn again, which will increase the pain of the patient and the burden of the national medical insurance; waste resources; increase medical waste

[0009] 7. Because traditional vacuum blood collection tubes use different types of anticoagulants to deal with corresponding inspection items, blood samples cannot be separated. Even if a secondary bloodletting port is set, the purpose of general detection cannot be achieved. Therefore, once there is a problem with the blood sample, or the detection When the results are in doubt, or when additional inspection items are required, no inspection and testing can be performed again

Due to the cumbersome extraction steps of natural hirudin, the difficulty of raising leeches, and the lack of sources of leeches, it is difficult to obtain a sufficient amount of pure products, which limits research and clinical applications.
