Problems solved by technology

The main reasons that affect wound healing are: 1. People who are malnourished have less plasma protein, and their daily nutrition is not enough to maintain their own daily nutrition, which affects wound healing. Patients with anemia often lack not only protein, but also oxygen, which makes the body's metabolism 2. The younger the age, the stronger the growth, the faster the wound healing, while the wound healing of the elderly is slower; 3. The wound healing is affected. Bacterial, fungal or viral effects can be slowed or stopped
[0003] Therefore, when human injections are performed clinically, the wounds produced by injections are generally Class A wounds, but the wounds of the injected patients may heal slowly, so that the needle holes are exposed to the air for a long time and infection occurs, which is harmful to people's health and safety. caused some harm

Embodiment 1

[0015] Embodiment 1, with reference to figure 1 The invention relates to an injection needle tube for assisting healing, which includes a needle tube body 2, and a growth factor layer 1 for promoting wound healing is coated on the outer surface of the needle tip of the needle tube body. The growth factor layer is formed by coating growth factors. Growth factors are organic substances that are necessary for regulating the normal growth and metabolism of microorganisms, but cannot be synthesized by themselves with simple carbon and nitrogen sources. In addition to vitamins, growth factors in a broad sense include bases, purines, pyrimidines, biotin, and niacin, and sometimes amino acids required by amino acid auxotrophic mutants; while growth factors in a narrow sense generally only refer to vitamins.

Embodiment 2

[0016] Embodiment 2, with reference to figure 2 , an injection needle tube for assisting healing, comprising a needle tube body, a growth factor layer 1 for promoting wound healing is coated on the outer surface of the needle tip of the needle tube body, and a layer of growth factor 1 is coated between the growth factor layer and the tube wall of the needle tip of the needle tube body Lubricant layer 3 that reduces the friction between the surface of the needle tube and human tissue.

Embodiment 3

[0017] Example 3, in the auxiliary healing injection needle described in Example 1 or 2: the lubricant layer is a silicone oil lubricant layer. The silicone oil lubricant layer can be lubricated by lubricants such as dimethyl silicone oil.

Abstract

The invention relates to a healing assistance injection needle tube comprising a needle tube body, wherein the outer surface of the needle tip of the needle tube body is coated with a growth factor layer promoting wound healing. According to the invention, a growth factor promoting wound healing and a needle tube lubricant coat the surface of the needle tube, wherein a growth factor promoting wound healing and a needle tube lubricant are attached to the surface of the needle tube in a layered manner, or a growth factor promoting wound healing and a needle tube lubricant coat the surface of the needle tube in a mixed manner, or a lubricating growth factor promoting wound healing coats the surface of the needle tube. After the needle tube punctures the skin and completes injection, the growth factor stays on the surface of the wound. The needle tube has a lubricating effect when puncturing the human body, so that the pain of patients is reduced, and the needle hole stopping bleeding can heal quickly.

Description

technical field [0001] The invention relates to a medical device, in particular to an auxiliary healing injection needle tube. Background technique [0002] At present, the process of wound healing after the skin is punctured by a needle tube (take the wound after intravenous injection as an example) is generally as follows: the first stage of hemostasis, the sticky platelets attach to the collagen to form a thrombus on the ruptured blood vessel; the second stage Stage inflammatory response, blood vessels and cells inflammatory response to the wound, through vasodilation, white blood cells enter to fight infection, resulting in reduced blood flow; third stage regeneration, the body replaces the scar in the wound by generating granulation (red granular tissue with blood vessels) After this stage, epithelium is formed, and then the wound is finally closed; in the fourth stage of tissue reconstruction, the collagen content in the wound continues to increase, so that the wound s...
