Description

TECHNICAL FIELD [0001] The present invention relates to a blood-collecting unit having a stick-restricting function, a blood-drawing unit, a drug-injecting unit, and a stick-

The present invention relates to a blood collecting unit having a stick-restricting function, a device for injecting a drug, and a stick-preventing unit.

Normally, the butterfly handle syringe has a needle on the front of the butterfly handle, and a bendable supply tube is connected to the back, which is used as a syringe for injecting or transfusing a patient with nutrients such as glucose.

Such a butterfly handle syringe is used to insert a needle into a patient's blood vessel and then fix the syringe to the skin using a bandage on the butterfly handle so that the needle does not come out of the blood vessel or the position of the syringe does not change However, it can be seen that the injected syringe of the butterfly handle is filled with the blood of the patient.

In this way, if a doctor or a nurse stabs an injection needle with a blood sample, there is a risk of infecting the patient's disease (a communicable disease such as hepatitis or AIDS).

In addition, human blood contains various military service, and blood is collected and various tests are carried out. In collecting blood, it can be seen that a normal syringe needle is introduced into the blood vessel, the plunger inserted in the barrel (cylinder) is moved back to collect blood, and the blood is drawn using a syringe.

The syringe dedicated for blood collection is designed to attach a syringe unit for blood collection to the body of the barrel in which a needle is formed on the front side of the barrel and on the inside of the barrel such that the injection needle is formed on the left side and the right side respectively. It can be seen that when the vacuum collection chamber is inserted into the injection needle, the blood is drawn to the collection container by the vacuum degree of the vacuum collection container.

Conventional blood sampling syringes are discarded in the state where the blood sampling needles are inserted in the front of the barrel body after the blood collection, and the blood of the patient is left on the blood sampling needle. If the needle of the used blood sampling syringe is inserted, Or other third person is stung, there is a risk of being infected with the patient's disease (hepatitis, AIDS, etc.).

Hereinafter, the configuration and function of the lancet unit 100 having a stick preventive function according to an embodiment of the present invention will be described. As described in the Background of the Invention, the lancet unit 100 having a stick preventive function according to an embodiment of the present invention corresponds to a blood sampling syringe and draws the outer needle 110 into a blood vessel, The upper surface of the blood collection chamber 160 is inserted into the inner needle 130 so that blood is introduced into the vacuum collection chamber 160 by differential pressure.

FIG. 6 is a perspective view of a lancet unit 100 having a stick preventive function according to an embodiment of the present invention. 7 is a side view of the lancet unit 100 having a stick preventive function according to an embodiment of the present invention. 8 is an exploded perspective view of a lancet unit 100 having a stick preventive function according to an embodiment of the present invention.

6 to 8, a lancet unit 100 having a stick preventive function according to an embodiment of the present invention includes a needle unit 120, an outer needle 110, an inner needle 130, The protection tube 131, the cover and shield unit 140, the cylinder 150 (barrel), and the like.

The needle unit 120 is formed in a cylindrical shape as a whole, but it is understood that the lower end portion is formed as a flat surface as shown in FIG. In addition, an inner needle attaching end 123 is provided at the rear end of the needle unit 120, and an outer needle attaching end 122 is provided at the front of the needle unit 120 so that the outer needle 110 is coupled. In addition, the through-hole 121 is formed to pass from the outer needle attaching end 122 to the inner needle attaching end 123.

The rear end of the outer needle 110 is coupled to the outer needle mounting end 122 of the needle unit 120 and is drawn into the human body. The inner needle 130 is also coupled to the inner needle mounting end 123 and inserted into the vacuum collection chamber 160 during the blood collection mode. Also, the backflow prevention protective tube 131 surrounds the inner needle 130 in a state where the vacuum collection chamber 160 is not inserted.

The cover and shield unit 140 have a hollow tube shape as a whole, but the lower end of the outer surface is formed as a flat surface. The needle unit 120 is inserted into the cover unit and shield unit 140 to move forward and backward with respect to the needle unit 120, The faces are also made of flat faces.

Therefore, in the blood collecting mode, the front end of the cover and shield unit 140 is located on the front side of the needle unit 120, and the outer needle 110 pulled out after the blood collection is detached, The cover 140 and the shield unit 140 are moved to the front side so as to be located inside the unit 140 to prevent sticking by the outer needle 110.
