  Shengjiu Mould introduces several common types of blood collection needle mould.

  1. Split blood collection needle mould

  Split blood collection needle mould is a disposable blood collection needle mould commonly used clinically. It basically replaces the syringe blood collection method used in the last century, and is often used in conjunction with disposable blood collection tubes.

  Its structure is to connect a blood collection needle to the needle seat at the end of the tube of the intravenous infusion needle. When in use, the blood collection needle needs to be rotated and fixed on the front end of the needle holder outer cylinder, and the vein puncture is carried out by holding the vein puncture. After successful, insert the vacuum blood collection tube into the back cavity of the needle holder so that the blood collection needle blade passes through The blood stopper is inserted into the rubber stopper of the vacuum tube, and the blood is sucked into the blood collection tube under the action of negative pressure. If necessary, repeat this procedure to achieve multi-tube blood collection; after blood collection, pull out the venipuncture needle to stop bleeding locally, remove the blood collection needle mould from the needle holder, and discard the venipuncture needle in the waste box.

  Features: After the blood collection needle mould is launched, the needle core will be locked, so that the blood collection needle mould can only be used once, which can ensure the safety of the user; the design of push-type launching provides the user with the easiest operation; high quality , The ultra-sharp three-sided needle design can quickly pierce the skin and reduce the patient's pain; a variety of needle types and piercing depths are suitable for most blood collection needs.

  2. Pen type blood collection needle mould

  Pen-type blood collection needle mould is not used much in clinical practice. Its structure is a penetrating needle tube with sharp cutting edges at both ends. The middle and lower section of the needle tube is fixed on the needle seat. The front end is called a venipuncture needle, and the back end is called a blood collection needle. The blood collection needle has a blood blocking sleeve and a needle tube on the surface. There is a protective sleeve at the end. In clinical practice, blood collection is usually used in conjunction with needle holders and disposable blood collection tubes.

  When using, rotate and fix the blood collection needle mould on the front end of the outer cylinder of the needle holder to perform venipuncture. After successful, insert the vacuum blood collection tube into the cavity at the rear end of the needle holder, so that the rear edge of the blood collection needle passes through the blood block sleeve And penetrating into the vacuum tube rubber stopper, under the action of negative pressure, the blood is drawn into the blood collection tube. Such repetition can realize the collection of multiple blood samples.

  3. Arterial blood collection needle mould

  Arterial blood sampling is of great significance for judging and treating hypoxemia. Arterial blood sampling is the basis for accurately judging hypoxemia.

  Features: The arterial blood gas syringe strictly fixes the needle to prevent the risk of needle looseness during the whole process of collecting arterial blood samples. The high molecular density of the blood collection needle mould barrel wall and the double closed needle plug effectively prevent the blood gas sample from gas exchange with the outside world. . Before blood sampling, the amount of blood collected can be preset according to the requirements of the test, so that the arterial puncture operation is safe and simple, and the waste of blood samples is avoided. The hole stone at the back of the syringe is designed to form a unique automatic exhaust device, which can quickly and safely exhaust the residual gas in the syringe under the action of arterial pressure, and avoid the interference of dead space gas on the arterial blood gas detection results.
