Safety blood collection set is an instrument used to collect blood samples during medical testing and is a type of single-use blood collection needle that comes in two types: press-on and locking snap-on. Safety blood collection set can minimize the possibility of infection of healthcare workers worldwide during the operation of collecting blood samples, such as HIV, hepatitis, and other diseases.
Safety lock blood collection set consists of a needle and a needle bar, the needle is located in the head of the needle bar, there is a sheath slidingly attached to the needle bar, and there is a reset spring between the sheath and the needle bar and the initial position of the sheath is located in the head of the needle and the needle bar.

With the continuous development of technology, blood collection set has gone through four generations of development history before the birth of disposable blood collection needles like safety blood collection sets.

First generation: Willow needle
Willow needle with a whole piece of metal sheet processing, needle length 3 ~ 4cm, resembling a willow leaf, the head has a fixed length of the needle tip, length of about 2 ~ 3mm, the bottom of the needle tip expansion, used to control the depth of the needle, the middle of a groove from the needle tip through to the end of the needle. Easy packaging, easy to be contaminated.

Second generation: Plastic compression molded set
Plastic compression-molded needles use plastic compression molding, the tip of the needle is made of stainless steel and other metals, and each needle is equipped with a plastic needle cap, the packaging is more independent. Take off the cap before use to prevent contamination, the needle is small, and proper operation will reduce the patient's pain and also reduce the patient's psychological pressure; it is inexpensive and can be used once.

The common disadvantages of the first and second-generation blood collection sets are painful, the size of the incision depends mainly on the experience and professional quality of clinical laboratory staff, the patient incision is too close to the staff's fingers or gloves, there is still the possibility of causing cross-contamination of blood between patients.

Third Generation: Mechanical blood collection set
Mechanical blood collection set adopts a mechanical device, and the needle adopts an ejection device, which can almost completely achieve an accurate, fast, moderately deep, and straight path to pierce the skin, greatly reducing the patient's pain. Solved the problems of the previous two generations of blood collection needles such as strong pain and large incisions.

Fourth generation: Laser blood collection set
The laser blood collection set uses the powerful energy of the laser to sear the tissue and penetrate the skin to form a bleeding point in an instant. The incision formed by this blood collection instrument is extremely small and the depth can be adjusted according to the patient's skin condition (which can be achieved by adjusting the laser intensity). In addition, there is no actual physical contact between this blood collection device and the patient, and even if a tiny spot of blood is ejected, cross-contamination of blood can be completely eliminated by replacing the laser emitter, making it a safer blood collection device.
Laser blood collection sets vary in appearance, both large and small, large like a microscope, small like a cigarette box, can be used for outpatient blood collection and bedside blood collection. Only in the process of blood collection, the laser blood collection needle will emit a crackling sound, and at the same time will emit a faint smell of burning flesh, so that some patients feel uneasy.

The principle of safety blood collection set is to use the vacuum negative pressure tube to suck blood. Safety blood collection set belongs to a vacuum negative pressure tube, in the prick to the blood vessels through the method of negative pressure attraction, the blood can be drawn out of the blood vessels, so as to achieve the effect of blood collection. Disposable blood collection sets, to avoid repeated use, but also to avoid the chance of cross-infection, most of the current use of disposable appliances.

After the safety sleeve is fired, the needle core will be locked, so that the needle can only be used once, which can ensure the safety of the user.
The safety sleeve is designed to provide the easiest operation for the user.
The safety sleeve has a cutting edge, length, and angle of the needle for venipuncture. The cutting edge is extremely smooth, resulting in less patient discomfort and residual pain after sampling.
The safety sleeve has a very smooth inner wall, which increases the speed of blood collection while preventing fragile blood cells from being adsorbed or damaged during the rapid passage, reducing blood cell breakage. The ultra-thin wall of the syringe minimizes puncture-induced tissue trauma, reduces tissue fluid infiltration, and improves specimen quality. And a wide range of needle sizes and penetration depths to suit most blood volume collection needs.

Safety blood sets are available in a variety of needle sizes and penetration depths to suit most blood collection needs.

Split blood collection set is a disposable blood collection 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 a blood collection needle. When used, the blood collection 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 collection needle passes through the blood barrier sleeve and pierces the vacuum tube plug, and blood is drawn into the blood collection tube under negative pressure. When needed, this can be repeated to achieve multi-tube blood collection; when the blood collection is completed, the venipuncture needle is withdrawn, local hemostasis is achieved, and the needle is removed from the needle holder and discarded in the waste box, together with the venipuncture needle.

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

Safety lock blood collection set, used for terminal blood collection, after use that is self-locking, can not be used again. The product is used alone and does not need to be matched with a blood collection pen.

a. First, wash and dry your hands thoroughly. Warming and massaging your finger to improve blood flow. Lower the arm briefly to allow blood to flow to the fingertips.

b. Open the protective cap of the blood collection set with one or both hands

c. Place the end of the safety settings on the selected blood collection site, press the thumb firmly against the interphalangeal joint where the blood is to be collected, and press to fire.

d. Place the used sleeve in the waste bin.

When unpacking the whole box of safety blood collection set, should pay attention to the expiration date of the blood collection set. Expired products can not be used, when unpacking blood collection needles, should pay attention to the outer packaging is not broken, if there is damage can not be used.

After tearing open the outer packaging of the single-use safety lock blood collection set, you should hold the tip the needle and the end of the needle with both hands and tense the needle hose with force. Explanation: Single-use blood collection needles are wrapped around
Placed in the outer packaging, curled hose has a certain elasticity, blood collection process, the tip of the needle is easy to slip out of the patient's body under the action of hose elasticity, some hose elasticity is greater, the tip of the needle slipped out of the patient's body, high-speed rebound piercing the operator's hand fixed blood collection tube, resulting in occupational exposure. If you can pull the hose hard before puncture, so that it loses its elasticity, you can avoid the tip of the needle slipping out of the patient's body under the action of the hose elasticity, to avoid the tip of the needle slipping out of the patient's body after continuing to rebound to break the operator's hand fixed blood collection tube.

Safety blood collection set tail end stabbed into the center of the blood collection tube plug, first with the right thumb, index finger and middle finger hold the end of the blood collection needle, let the end of the needle and blood collection tube plug plane is about 45 ° angle, and make the middle finger and blood collection tube plug tightly fixed, and then the middle finger as a support point, turn the right hand so that the end of the blood collection needle vertical stabbed into the center of the blood collection tube plug. This technique can better prevent the end of the needle from slipping out and injuring the operator's hand when piercing the center of the blood collection tube.

When collecting blood from patients, the blood collection tube held in the left hand should be fixed on the operating table to prevent the needle from being pulled out of the patient's body due to the unstable suspension of the blood collection tube in the hand.

When collecting blood specimens, the negative pressure of the test tube has been exhausted, and the blood remaining in the blood collection needle can not continue to enter the test tube after the needle is removed, easy to make the blood in the blood collection needle dripping contamination of the operating table and the operator. Therefore, after the blood is drawn, the tourniquet should be loosened and the puncture needle removed before separating the blood collection needle from the vacuum tube so that all the blood in the silicone hose of the blood collection needle enters the blood collection tube.
