Description

Technical Field

[0001] The present application relates to the technical field of fixing devices, and more specifically, to a hand fixing device for infusion. Background Art

[0002] Intravenous infusion is a method of injecting large amounts of sterile liquids, electrolytes, and drugs into the body through veins by utilizing the principles of atmospheric pressure and liquid static pressure. The injection of large amounts of liquids, electrolytes, or blood into veins is called intravenous infusion. Due to the differences in the injection site and the infusion, it can be divided into peripheral intravenous infusion, central venous infusion, high-nutrition infusion, and blood transfusion. When giving an infusion to a patient, a hand fixation device is generally used to reinforce the patient's arm to prevent the needle from falling off due to the patient's hand movements.

[0003] The document with prior art publication number CN215309259U provides a hand fixing device for infusion. When installing the fixed installation box, first insert the positioning head into the inside of the seat armrest to prevent deviation, rotate the rotating wheel, the rotating wheel drives the connecting rotating rod and the active bevel gear to rotate, the active bevel gear drives the driven bevel gear to rotate, the driven bevel gear drives the screw to rotate, the screw controls the movement of the installation rod until the installation rod is completely inserted into the inside of the seat armrest, so that it can be easily installed in conjunction with the hospital chair.

[0004] Although the device has many beneficial effects, the following problems still exist: when the patient is given an infusion, the needle is sometimes inserted into the patient's hand at the vein of the hand. When the vein of the patient's hand is not obvious enough, sometimes the needle needs to be inserted into the patient's arm. However, it is difficult for the above device to effectively adjust the fixed position according to the specific situation of the patient's infusion position, thereby reducing the flexibility of the device when used. In view of this, we propose an infusion hand fixing device. Utility Model Content

[0029] The fixing mechanism 3 includes a slide plate 31, which is slidably connected in the through groove, and support plates 33 are fixedly connected on both sides of the top of the slide plate 31, and elastic Velcro 34 is fixedly connected on the top of the support plate 33. Slots are provided on both sides of the supporting plate 2, and a plurality of vertical rods 35 are fixedly connected inside the slots. A mounting groove is penetrated through one side of the support plate 33, and a movable block 36 is slidably connected in the mounting groove. A mounting ring 37 is fixedly connected on one side of the movable block 36, so that the staff can adjust the fixed position according to the specific position of the patient's infusion needle insertion, thereby improving the flexibility of the device when used.

[0030] Reference Figure 1 and Figure 2 Slide grooves are provided on both sides of the bottom inner wall of the through groove, and sliders 32 are fixedly connected to both sides of the bottom of the slide plate 31. The sliders 32 are slidably connected in the slide grooves, so that the slide plate 31 can move horizontally.

[0031] Reference Figure 1 and Figure 2 The cross-sections of the slider 32 and the slide groove are both in a convex shape, thereby preventing the slide plate 31 from escaping from the through groove.

[0032] Reference Figure 1 and Figure 2 The size of the inner side of the mounting ring 37 is equal to the size of the two ends of the vertical rod 35, so that after the mounting ring 37 is sleeved on the outer side of the vertical rod 35, the support plate 33 and the slide plate 31 can no longer move horizontally.

[0033] Reference Figure 2 Two of the elastic Velcro strips 34 are hook surfaces, and the other two elastic Velcro strips 34 are velvet surfaces, so that the two elastic Velcro strips 34 on the same slide plate 31 can be bonded to each other.

[0034] Reference Figure 3 A guide rod 38 is fixedly connected in the installation groove, and the movable block 36 is slidably sleeved on the outside of the guide rod 38, so as to prevent the movable block 36 from being separated from the installation groove.

[0035] Reference Figure 3 The other side of the movable block 36 is fixedly connected with a pull rod, and the cross section of the pull rod is T-shaped, so that the staff does not need to put their hands into the installation groove to push the movable block 36 to move upward.

[0036] Reference Figure 3A spring 39 is fixedly connected to the top of the movable block 36, the top of the spring 39 is fixedly connected to the top of the inner wall of the mounting groove, and the spring 39 is sleeved on the outside of the guide rod 38, so as to prevent the movable block 36 from rising and moving at will.

[0038] The implementation principle of the hand fixing device for infusion in the embodiment of the present application is as follows: when the patient's hand needs to be fixed, the staff can pull the movable block 36 to move upward, so that the movable block 36 drives the mounting ring 37 to move upward and squeeze the spring 39, so that the mounting ring 37 is separated from the vertical rod 35. At this time, the staff can push the slide plate 31 to move horizontally. The movement of the slide plate 31 can drive the support plate 33 and the elastic Velcro 34 to move. When the elastic Velcro 34 moves to the specified position, the staff can release the movable block 36, so that the squeezed spring 39 returns to its original position and rebounds to drive the movable block 36 and the mounting ring 37 to move downward, so that the mounting ring 37 is sleeved on the outside of the vertical rod 35, thereby facilitating the staff to adjust the position of the elastic Velcro 34 so that the infusion needle is located between the two groups of elastic Velcro 34. Then the staff can bond the two elastic Velcro 34 on the same slide plate 31 to bind and fix the patient's arm or hand.

[0039] An embodiment of the present application provides a hand fixing device for infusion. By setting a fixing mechanism 3, when performing infusion on a patient, the position of the elastic Velcro 34 can be adjusted according to the position of the needle insertion on the patient's hand, so that the fixing position of the patient's hand can be adjusted, thereby improving the flexibility of the device when used.
