Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of syringes, and particularly discloses a syringe head for drawing blood from a plant or bone graft wound. Background Art
[0002] Plastic syringes are a common medical device, mainly used for injecting or withdrawing liquids. They are usually made of plastic materials such as polyethylene or polycarbonate. These materials have excellent physical and chemical properties and can meet the medical field's requirements for sterility, transparency, and corrosion resistance. Plastic syringes usually consist of a syringe, piston, piston rod, protective cap, and injection needle.
[0003] In the process of implanting teeth for patients, when doctors encounter insufficient bone or poor growth of the extraction socket wound, bone grafting is required. Before bone grafting, an appropriate amount of bone powder needs to be poured into a container, and blood on the original wound needs to be drawn using a syringe. The blood and bone powder are mixed and then transplanted to the corresponding position. Since the blood required for mixing bone powder is not much, in order to reduce the waste of patient blood, only a small amount of blood from the original wound needs to be drawn, and there is no need to draw blood from other parts to avoid creating new wounds and increasing patient discomfort. The injection tube at one end of the traditional syringe is relatively hard, and the end face of the injection tube cannot fit the wound surface well, resulting in low blood extraction efficiency. The doctor needs to draw blood multiple times, and during the multiple blood extraction processes, the hard injection tube is very likely to cause secondary damage to the patient's wound surface, further increasing the patient's discomfort. If a needle is connected to one end of the injection tube, it is more likely to puncture the wound surface, increasing the probability of secondary damage to the wound surface, which is not conducive to the patient's later recovery. Therefore, in order to solve the above problems, the utility model proposes a blood extraction syringe head for bone grafting wound. Utility Model Content
