[0029] Intravenous infusion is a method of injecting large amounts of sterile liquids, electrolytes, and drugs into the body through veins by using the principles of atmospheric pressure and liquid static pressure. Intravenous infusion needles are used to connect syringes, infusion sets, and blood transfusion sets for intravenous infusion of drugs and blood transfusions.
[0030] In the related art, during the actual use of the intravenous infusion device, the patient consciously or unconsciously moves the body position and pulls the infusion tube, so that the needle cannot maintain its original position, and the needle is easy to move out of or pass through the blood vessel wall, causing the infusion liquid to flow into the inner layer of the muscle, causing local swelling, infection and suppuration of the patient, seriously affecting the patient's treatment effect. In clinical practice, the needle is usually fixed with ordinary tape during intravenous infusion.
[0031] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides an intravenous infusion needle holder. When it is needed, the patient's arm only needs to be placed on the top of the support block 11, and then the limit frame 14 is rotated to rotate it directly above the patient's arm, and then the movable plate 12 is pressed down. The limit frame 14 squeezes and limits the patient's arm. After the limitation is completed, the limit plate 16 is rotated to lower the limit plate 16. After lowering it, it is fixed by rotating the bolts set on one side of the limit plate 16, and then the infusion needle is punctured into the patient's hand. The patient's arm is placed on the bottom of the infusion needle fixing block 19, and the infusion needle needle is fixed by the infusion needle fixing block 19. In this way, cross infection due to hygiene problems can be reduced.
[0032] The present application is described below with reference to the accompanying drawings and specific embodiments:
[0033] Combination Figure 1-Figure 4 The embodiment of the present application provides an intravenous infusion needle holder, including an infusion fixing component 1; the infusion fixing component 1 includes: a support block 11 having a groove 111 on the top; a movable plate 12 inserted into the inner side of the groove 111; a rotating rod 13 rotatably arranged on the top of the movable plate 12; a limit frame 14 is arranged on the top of the rotating rod 13; a rod body 15 is arranged on the limit frame 14; a limit plate 16 is rotatably arranged on the rod body 15; an extension plate 17 is arranged on the support block 11; a frame 18 is arranged on the extension plate 17; an movable rod 181 is arranged on the top of the frame 18 and passes through the frame 18; an infusion needle fixing block 19 is arranged at the bottom of the movable rod 181; a spring 191 is sleeved on the outer side of the movable rod 181.
[0034] When in use, the patient's arm is first placed on the inner side of the support block 11. After placement, the rotating rod 13 is rotatably connected to the movable plate 12, so the limit frame 14 can be rotated to rotate it to the patient's arm, and then the movable plate 12 is pressed down to limit the patient's arm through the limit frame 14, and then the limit plate 16 is rotated to lower the limit plate 16, and then it is fixed by the bolts set on one side of the limit plate 16, and then the infusion needle is punctured into the patient's hand, and the patient's arm is placed at the bottom of the infusion needle fixing block 19, and the infusion needle needle is fixed by the infusion needle fixing block 19, so that cross infection due to hygiene problems can be reduced.
[0035] In some embodiments, an auxiliary component 2 is disposed on the limiting frame 14 , and the auxiliary component 2 includes a limiting groove 21 opened on the top of the limiting frame 14 .
[0036] A limiting groove 21 is opened at the top of the limiting frame 14, so that the infusion tube can be placed inside the limiting groove 21 and then fixed with tape. This can limit and fix the infusion tube and also play a limiting role when dragging occurs, preventing the infusion needle from detaching and protecting the patient's infusion site.
[0037] In some embodiments, the auxiliary component 2 further includes a spring 22 disposed on the inner side of the groove 111 .
[0038] A plurality of springs 22 are arranged at the inner bottom of the groove 111, so that the elasticity of the springs 22 can drive the limit frame 14 on the top of the movable plate 12 to descend to squeeze and fix the patient's arm, thereby preventing the movable plate 12 from shaking easily and increasing the structural stability of the device.
[0039] Specifically, two ends of the second spring 22 are respectively welded and fixed to the movable plate 12 and the support block 11 .
[0040] In some embodiments, the auxiliary component 2 further includes: a slot 23 is opened on the support block 11 and plugged into the extension plate 17; a screw rod 24 is arranged at the bottom of the support block 11 and is threadedly connected to the support block 11.
[0041] A slot 23 is opened on one side of the support block 11, and the extension plate 17 is inserted into the inner side of the slot 23, so that the extension plate 17 can be put away after subsequent use to avoid collision due to its large size. Then, the screw 24 threadedly connected to the support block 11 is rotated to screw it into the inner side of the slot 23 and fix the extension plate 17 to prevent it from falling off.
[0042] In some embodiments, the auxiliary component 2 further includes: a protective pad 25 disposed on the inner side of the limiting frame 14 and the supporting block 11 respectively.
[0043] Protective pads 25 are provided on the inner side of the limiting frame 14 and the inner side of the supporting block 11 respectively, so as to protect the patient's arm and prevent the patient from contacting hard objects during infusion, thereby reducing the patient's discomfort.
[0044] Specifically, the protection pad 25 is fixed to the limiting frame 14 and the support block 11 respectively by bonding.
[0045] In some embodiments, the auxiliary component 2 further includes a rubber pad 26 disposed on the limiting plate 16 .
[0046] A rubber pad 26 is disposed on one side of the limiting plate 16 , so that the limiting effect between the limiting plate 16 and the supporting block 11 can be increased by increasing the friction force, so as to facilitate subsequent bolt fixing.
[0047] In some embodiments, the auxiliary component 2 further includes: a screw rod 27 disposed on the top of the infusion needle fixing block 19 and threadedly connected to the movable rod 181 .
[0048] A screw rod 27 is arranged on the top of the infusion needle fixing block 19 and is threadedly connected to the movable rod 181, so that after use, the infusion needle fixing block 19 can be screwed down for disinfection or replacement to avoid affecting the next use, thereby increasing safety.
[0049] In some embodiments, the auxiliary component 2 further includes a column 28 disposed at the bottom of the frame 18 .
[0050] A column 28 is provided at the bottom of the frame 18, and the column 28 is sleeved on the outside of the spring 191, so that the spring 191 is prevented from being exposed to the outside, the spring 191 is protected, and the aesthetics of the device is increased.
[0051] Specifically, the column 28 and the frame 18 are fixed by welding.
