Description

A medical infusion fixation device

technical field

The invention relates to the technical field of medical nursing, in particular to a medical infusion fixing device.

Background technique

At present, intravenous infusion has become one of the most important means in medical work. By using intravenous infusion, the patient's condition recovers quickly and the balance of body fluids and electrolytes can be maintained. In clinical infusion, the back of the patient's hand is generally punctured. When the patient's hand movement reaches a certain intensity during the infusion process, the needle will be prolapsed from the blood vessel or the blood vessel will be partially prolapsed and the blood vessel will be subcutaneously or the needle will penetrate the blood vessel. down, commonly known as "running the needle". After "running the needle", there may be edema, bleeding, pain and other phenomena at the infusion site. In severe cases, there may be a large amount of bleeding and bruising, and the function of continuing infusion may be lost.

Now there are some support tools for infusion on the market, most of which are combined with a sticky buckle and a base plate. However, the current support tools have the problem of not being fixed firmly, and the palm and back of the patient's infusion side are still prone to bending, If the position changes, it is easy to pull the skin and muscles on the back of the hand, affecting the fixation of the needle, resulting in poor infusion and blood vessel damage.

In one embodiment, in order to improve the comfort of the joint pressing plate 3 , a sponge pad 92 is provided on the bottom surface of the first plate body 31 .

In one embodiment, the wrist strap includes a first adhesive strip 21 and a second adhesive strip 22 . One end of the first adhesive strip 21 is fixed on the base plate 1 , and one side of the first adhesive strip 21 is provided with a Velcro matte surface. One end of the second adhesive strip 22 is fixed on the bottom plate 1, and one side of the second adhesive strip 22 is provided with a hook surface of the Velcro, and the hook surface of the Velcro and the wool surface of the Velcro can be bonded to each other. Through the bonding and cooperation of the first adhesive strip 21 and the second adhesive strip 22 , the wrist strap can adjust the degree of tightness during fixation, and also increases the firmness of fixation, thereby restricting the movement of the back of the patient's hand.

In one embodiment, the operating mechanism 8 includes a reset member 81, a pull wire 82, a fixed pulley 83 and an operating rod; one end of the reset member 81 is connected to the groove wall of the groove 11, and the other end of the reset member 81 is connected to the first clamp plate 6 The reset member 81 is used to reset the first splint 6 , and one end of the pull wire 82 is connected to the end of the first splint 6 far from the reset member 81 . The side wall of the bottom plate 1 is sequentially provided with accommodating grooves 15 and screw holes 16 which communicate with each other from the outside to the inside along its width direction. A wire-passing hole 17 is opened between the accommodating groove 15 and the groove 11, and the wire-passing hole 17 is respectively connected with the groove 11. It communicates with the accommodating groove 15 . The fixed pulley 83 is rotatably arranged at the bottom of the groove 11, and the operating rod includes a stud 84, a winding column 85 and a connecting column 86 that are connected in sequence. Inside the slot 15, the pulling wire 82 bypasses the fixed pulley 83 and passes through the wire hole 17, and then is wound on the winding post 85; the connecting post 86 extends out of the accommodating slot 15 and is provided with a handle 87.

The steering connector 5 includes a first rotating shaft 51 , a support plate 52 , two U-shaped frame bodies 53 and two second rotating shafts 54 .
