The existing product and the technical scheme have the defects of difficult product production and poor operation performance due to the structural or technological problems, so that the product is difficult to be practically applied and popularized. The defects of the existing product and technology are as follows:
1. after the existing transfusion needle is butted with a puncture type connecting piece of an indwelling device, a protection or fixing device is not arranged, the existing transfusion needle cannot be connected in a suspended way and can only be fixed on the limbs of a person.
2. After the existing transfusion needle is butted with the puncture type connecting piece of the indwelling device, the adhesive tape can not stably fix the transfusion needle seat and the puncture type connecting piece, so that the root of the transfusion needle is easily subjected to breaking force, and the needle breaking phenomenon occurs.
3. The tape fixation causes the patient to receive more tape and may cause the probability of allergy to be increased, and the operation is troublesome.
4. The existing non-safety and safety transfusion needles are unreliable, the accidental needle stick injury can not be completely avoided in the operation, and the special transfusion device for preventing needle stick can not puncture different parts.
5. In the actually used intravenous infusion needle, because the single-wing or double-wing handles of the infusion needle are suspended without supporting parts after connection, the steel needle is stressed after being fixed by the adhesive tape, the steel needle and the adhesive tape at the fixed part are stressed bidirectionally and the needle folding phenomenon is possible to occur.
6. The existing transfusion needle steel needle is a long needle with an inclined opening, is easy to break, and has a needle tip which touches the side wall of a transfusion device in the connection process to enable the needle tip to be barbed, so that the sealing element of the puncture type connecting piece is damaged.
7. The existing safe transfusion needle can not be connected with a puncture type connecting piece on a Y-shaped indwelling needle.
8. We find in clinical investigation that the needle tip of the existing transfusion needle tube is an inclined-mouth needle, and the defects of the existing transfusion needle tube when used for connection transfusion of an indwelling needle are as follows: when the puncture type connecting piece is punctured, the puncture opening is a line, the needle tube enters after being propped open, and the opening of the needle tube is positioned on the inclined plane of the needle point, so that various substances on the puncture line, including microorganisms, various particles and various organic or inorganic substances, are easily brought into an infusion apparatus system by puncturing, and nosocomial infection and other hazards can occur.
