Disposable soft 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 relates to a disposable soft connecting band collection container and an anti-freezing vacuum blood taking needle of a bleeding opening. The disposable soft connecting band collection container is formed in the following mode that: a biological product anticoagulant coating layer is arranged on an inner cavity wall of a circular connector; one end of the connector is provided with a blood taking plastic duct; a vacuum valve is placed on the plastic duct; the other end of the plastic duct is provided with the circular connector; the inner cavity wall of the circular connector is provided with the biological product anticoagulant coating layer; one end of the connector is provided with a venous blood taking needle, while the other end is provided with a 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 a secondary bleeding opening. The disposable soft connecting band collection container and the anti-freezing vacuum blood taking needle of the bleeding opening can ensure that a blood sample generates no cruor and hemolysis so as to ensure the accuracy of the test result. The blood dosage during the test can be controlled flexibly so as to ensure repeated tests at any time or the addition of 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 a medical disposable flexible joint belt collection container and a bloodletting port. Background technique [0002] At present, the traditional soft-connected blood collection needles in my country have the following disadvantages: [0003] 1. Traditional soft-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 soft-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...

Problems solved by technology

[0003] 1. Traditional soft-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 soft-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 soft-connected blood collection needle, and 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.
