Description
Technical Field
The invention relates to the field of medical instruments, in particular to a disposable infusion needle which is specially used for puncture connection infusion of products such as an indwelling needle, a central venous catheter and the like which are provided with puncture type connecting pieces.
Background
In actual clinical transfusion, the intravenous infusion needle is used for human body intravenous puncture transfusion, and is often connected with transfusion indwelling devices such as an indwelling needle and a central venous catheter, namely, the indwelling devices such as the indwelling needle and the central venous catheter are placed in the vein of a patient in advance. In long-term clinical studies, we found the following disadvantages in the prior art:
1. after the existing transfusion needle is butted with a puncture type connecting piece of an indwelling device, a supporting piece is not arranged, the existing transfusion needle cannot be connected in a suspended way, and only can 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 venous 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, which may cause an increased chance of allergy, and the operation is troublesome.
4. Other special transfusion needles can not be connected with a puncture type connecting piece simultaneously.
5. The existing intravenous infusion needle is easy to cause accidental needle puncture injury in operation.
6. The existing transfusion needle, in particular to the transfusion needle which is commonly used for a puncture type connecting piece and is 0.7-0.9, is overlong in length and is easy to break.
7. The puncture end of the puncture type connecting piece is made of sealing rubber materials, and the steel needle is difficult to insert to the bottom due to resistance, so that the puncture end face of the infusion needle can not play a role even if the infusion needle faces the puncture end face of the connecting piece and is abutted to the puncture end face.
8. The existing safe transfusion needle can not be connected with a puncture type connecting piece on a Y-shaped indwelling needle.
9. 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.
