Example 1

Please refer to Figures 1 to 4. This embodiment provides a fixation device for a vascular puncture indwelling needle, which includes an indwelling needle assembly 1. The indwelling needle assembly 1 includes a positive pressure connector 14, and a fixing assembly 2 is connected to the positive pressure connector 14. The component 2 fixes the indwelling needle component 1 on the patient's hand in a telescopic manner. The fixing component 2 wraps the indwelling needle component 1 when fixing the indwelling needle component 1. A strap component 3 is slidably connected to one side of the fixing component 2. The strap component 3. Adjust the position of the fixed indwelling needle assembly 1 by sliding inside the fixed assembly 2.

First, the specific structure of the fixing component 2 is disclosed. The fixing component 2 includes two fixing rings 21 fixedly provided on the positive pressure joint 14. Both sides of the two fixing rings 21 are provided with anti-falling rings 22. The anti-falling rings 22 The lower end of the connecting rod 23 is provided with a connecting rod 23, one end of which is slidingly connected to the opening of the fixed rod 24, the other connecting rod 23 is fixedly connected to the fixed rod 24, and the bottom of the opening of the fixed rod 24 and the connecting rod 23 pass through The elastic members 26 are connected, and a Velcro 28 is provided between the lower ends of the two anti-fall rings 22. The patient's hand is inserted into the anti-fall rings 22. Since there are elastic members 26 in the opening on one side of the fixed rod 24, the elasticity The member 26 preferably uses a spring as the equipment, so when the patient's hand enters the inside of the anti-fall ring 22, the anti-fall ring 22 is pushed to move, so that the anti-fall ring 22 carries the connecting rod 23 to stretch the elastic member 26, and the patient's hand is not present When moving, the elastic member 26 loses force, causing the anti-drop ring 22 to fit closely with the patient's hand, thereby fixing the positive pressure joint 14. Next, the Velcro 28 on both sides are pasted to each other, so that the positive pressure joint 14 is wrapped. ;

In addition, an anti-bending plate 25 is provided between the two fixed rods 24. The anti-bending plate 25 fits the inside of the patient's palm. The anti-bending plate 25 can be made of rubber. The anti-bending plate 25 can assist the patient's hand to keep straight. , will not bend it to affect the indwelling needle;

Moreover, medical tape 27 is provided on the lower side of the two fixing rings 21. The medical tape 27 is attached to the outside of the patient's palm, and the medical tape 27 is attached to the upper side of the patient's palm to further improve the stability of the positive pressure joint 14;

After the positive pressure connector 14 is fixed, the excess infusion tube needs to be bent and fixed together with the indwelling needle. Therefore, in order to fix the infusion tube and the indwelling needle at any position, the specific structure of the strap assembly 3 is disclosed. The strap assembly 3 It includes an adjusting rod 31. One end of the adjusting rod 31 is slidingly connected to the sliding hole 29 opened on one side of the anti-fall ring 22. The other end of the adjusting rod 31 is provided with an adhesive tape 32. According to the required length, the adjusting rod 31 is removed from the sliding hole 29. Slide it out, and then stick the adhesive tape 32 to wrap and fix the position that needs to be fixed.

On the other hand, the present invention also provides a vascular puncture indwelling needle, which includes a positive pressure connector 14. The positive pressure connector 14 is connected to the needle seat 11 through the catheter 13. One end of the needle seat 11 is provided with a needle 12.

To sum up, the working process of the overall device is as follows: put the patient's hand into the anti-drop ring 22. When the patient's hand enters the inside of the anti-drop ring 22, push the anti-drop ring 22 to move, so that the anti-drop ring 22 is The elastic member 26 is stretched by the connecting rod 23. When the patient's hand is no longer moving, the elastic member 26 loses force, causing the anti-drop ring 22 to fit closely with the patient's hand. At the same time, the medical tape 27 is used to further fix the effect, and then the elastic member 26 loses force. The positive pressure joint 14 is fixed on the patient's hand, and then the Velcro 28 on both sides are pasted to each other so that the positive pressure joint 14 is wrapped. At the same time, according to the required length, slide the adjustment rod 31 out of the sliding hole 29, and then The adhesive tape 32 is adhered to the position that needs to be fixed to wrap and fix it, and the anti-bending plate 25 is used to support the palm to prevent the patient's hand from bending.
