Embodiment Construction

[0047] Such as Figure 1-Figure 9 As shown, the present invention has a U-shaped underframe 7 connected with the door-shaped bracket 4 in an L-shape, and the door-shaped bracket 4 and the underframe 7 jointly form an anti-movement frame, and the front end of the said underframe 7 has an opening , so that the line of sight will not be affected when the needle is inserted. The rear end surface of the door-shaped support 4 is connected at right angles to the underframe 7, and the front end is connected to the underframe 7 on an inclined plane (see Figure 7 ), to strengthen the traction effect of the door-shaped bracket 4 on the underframe 7, which can prevent the underframe 7 from opening or deforming. An adhesive layer 10 capable of bonding to human skin is fixed on the bottom surface of the chassis 7, and the adhesive layer 10 also has a cover. There is a door-shaped hole 13 in the middle of the door-shaped bracket 4 . Respectively be provided with a protruding pin 5 (refer...

Abstract

The invention relates to a vascular protector for transfusion. A needle handle (1), a needle handle head (6), a needle stem (9) and a fin (2) are connected with the bottom of a fin bracket (3) into an integral body; pins (5) on both sides of a portal bracket (4) are clamped in pin holes (11) of the fin bracket; and the fin bracket (3) is matched with the pins (5) through the pin holes (11) and a clamping groove (12), and can rotate around the pins (5). The combination of the fin bracket and motion preventing bracket of the protector is very scientific, so that the fin bracket and motion preventing bracket are very convenient and simple in the production, assembly and transfusion processes. The vascular protector has a light structure. The vascular protector has excellent fixation effect with the skin of the patient; the length of the needle stem is more scientific and reasonable; and thus, the vascular protector can protect the patient vessels in many aspects, and maximally relieve the patient vessels of mechanical injury.

Description

technical field [0001] The invention relates to a medical device for transfusion, in particular to a transfusion blood vessel protector. Background technique [0002] When using a disposable infusion set for intravenous infusion, although there is tape to fix the needle and the front end of the infusion tube connected to it, but because the needle is not firmly fixed, the blade of the needle handle slides relative to the skin, and the vein bends, when the patient's limbs occasionally During the movement, the phenomenon of needle running is prone to occur, causing blood vessel damage, resulting in pain, swelling, heavy tying and waste of liquid medicine. [0003] In clinical intravenous infusion, the longer the length of the needle, the greater the mechanical stimulation and damage area of ​​the needle stem to the blood vessel wall, the more serious the damage, the more blood components leak out, the blood vessel congestion is obvious, resulting in connective tissue hyperplas...
