Vacuum Blood Collection System Makes the Process Safer and Easier For Patients

 

Vacuum Blood Collection System 

Vacuum Blood Collection System is a medical device used in the blood draw procedure known as venipuncture. The vacuum pressure generated by the system makes the process of drawing blood safer and easier for patients, and it allows the sample to be retrieved from the patient without contaminating the test site or introducing contaminants. The device is also designed to be easy to use for operators, helping them reduce their fatigue and stress. The demand for such vacuum blood collection system is expected to grow significantly in the coming years, as more laboratories begin to offer testing services utilizing these devices.

In order to maintain a low pressure inside the vessel during the collection of whole blood, the inventors developed a vacuum blood-collection tube made of specific raw materials. The raw material of the vessel is polyethyleneterephthalate or a copolymer of polyethyleneterephthalate, and it has a very low level of hydrophilicity, thereby preventing water molecules from being adsorbed on the inner surface of the wall where it touches the blood. The separation of the serum and blood clot can be effectively achieved in this kind of vacuum blood-collection tube, and the serum obtained by centrifugation is able to be stored for long periods of time at very low temperatures.

Furthermore, there is also a laminated film which can act as a gas barrier. The layered film consists of, from the outside, drawn polypropylene 20 mm thick and an ethylene-vinylalcohol copolymer (trade name EVAL, CRARE Co.), and it is filled with a gas such as nitrogen at a pressure of about 1.2 atmospheres. When the vacuum blood-collection tubes of the same capacity as those used in the test were wrapped with this laminated film and then placed inside a plastic wrapping that could not be easily torn, they were able to be maintained under very high conditions of vacuum for extended periods of time.

The vacuum blood collection system of the present invention includes a tube-shaped vessel having an opening through which air can be removed and a plug that makes this opening air-tight to maintain a low pressure condition in the vessel, and blood coagulation accelerant incorporated on the inner walls of the vessel, and a serum-separator. This kind of vacuum blood collection system can be used in pathology laboratories.

It is also possible to store the serum obtained by centrifugal separation of the blood clot and the blood in this kind of vacuum blood-collection tubes for up to about 340 hours, which is about seven-fold longer than the storage time that can be achieved with similar vacuum blood-collection tubes made of glass. In August 2022, Thorne HealthTech, Inc. announced to have certified its OneDraw Blood Collection Device in Japan as a medical device.
