Classification of medical comsumables such as blood taking needles

A blood taking needle is an instrument used to collect blood samples during medical testing and consists of a needle and a needle bar. The following is an introduction to the classification of blood taking needles and the characteristics of each type.

Here is the content list:

• Split type

• Pen Needles

• Arterial blood taking the needle

Split type

The split blood taking needle is disposable blood taking needle commonly used in clinical practice, basically replacing the syringe blood collection method used in the last century, often in conjunction with a single-use blood collection tube.

Its structure is in the IV needle hose end of the needle seat, connected to the blood taking needle. When used, the blood taking needle needs to be rotated and fixed in the front of the outer barrel of the needle holder, and the venipuncture needle is held to puncture the vein, and after success, the vacuum blood collection tube is inserted into the cavity at the back end of the needle holder, so that the blade of the blood taking needle passes through the blood blocking sleeve and pierces the vacuum tube rubber plug, and blood is drawn into the blood collection tube under negative pressure. When needed, so repeatedly, multiple blood collection tubes can be realized; when blood collection is completed, the venipuncture needle is withdrawn, local hemostasis is achieved, and the blood taking needle is removed from the needle holder and discarded in the waste box together with the venipuncture needle.

Features: After the blood taking needle is fired, the needle core will be locked, making the blood taking needle can only be used once, which can ensure the safety of the user; the design of the press-fire provides the easiest operation for the user; the high-quality, ultra-sharp trigeminal needle design can quickly pierce the skin and reduce the patient's pain; a variety of sizes of needle types and piercing depth, suitable for most of the blood collection needs.

Pen Needles

The pen-type blood taking needle is not used much in the clinic. Its structure is through the needle tube, both ends have sharp edges, the lower part of the needle tube fixed on the needle seat, the front end is called venipuncture needle, the rear end is called blood taking needle, blood taking needle surface has a blocking sleeve, the two ends of the needle tube have a protective sleeve. In clinical practice, it is usually used together with a needle holder and disposable blood collection tube to collect blood.

When used, the blood taking needle is rotated and fixed in the front of the outer barrel of the needle holder, the vein is punctured, and after success, the vacuum blood collection tube is inserted into the cavity at the back end of the needle holder, so that the blade at the back end of the blood taking needle passes through the blood barrier sleeve and penetrates the vacuum tube plug, and blood is pumped into the blood collection tube under negative pressure. So repeatedly, can realize the collection of multiple tubes of blood specimens.

Arterial blood taking the needle

Arterial blood collection is of great importance for the determination and treatment of hypoxemia. Arterial blood collection is the basis on which hypoxemia can be accurately determined.

Features: arterial blood gas syringe strictly fixed needle to prevent the danger caused by needle loosening during the whole process of collecting arterial blood samples, blood collection syringe wall highly molecular dense and double sealed needle plugs effectively prevent the blood gas specimen and the outside world from the gas exchange. The volume of blood can be preset according to the needs of the test, making arterial puncture safe and easy and avoiding waste of blood samples. The unique automatic air venting device at the rear end of the syringe is designed to quickly and safely vent residual gas from the syringe under arterial pressure, avoiding interference of dead gas with arterial blood gas test results.
