Abstract
Description
Technical Field
[0001] The present invention relates to the field of medical supplies, and particularly to an infusion fixator. Background Art
[0002] During the entire infusion process, the optimal state is that the infusion needle needs to maintain a certain angle conforming to the human biological angle to allow the liquid to flow smoothly and not shift, ensuring the stable and normal infusion. Currently, in clinical practice, only simple medical tapes are used to fix the needle. Since the patient may move their limbs during infusion, it is easy for the needle to shift or jump, resulting in blood reflux and affecting normal infusion. To avoid the above problems, the infusion fixator of the present invention is used to stabilize the needle, always maintain the human biological angle, is simple and convenient to operate, and is not easy to fall off, meeting the clinical needs. Summary of the Invention
[0003] The purpose of the present invention is to solve the above problems and design an infusion fixator.
[0004] To achieve the above purpose, the technical solution of the present invention is an infusion fixator, including a fixing block. A groove is inwardly opened on one surface of the fixing block. The plane of the groove of the infusion fixator forms an inclination angle of 4° - 10° with the horizontal plane. The cross-section of the groove is triangular. A notch communicating with the groove is linearly opened at the central position of the upper surface of the fixing block. The cross-section of the fixing block is triangular. The fixing block is composed of two trapezoidal blocks and a gradient block connected at the center. A sticky patch matching its shape and size is provided on the lower surface of the fixing block. The width of the notch is 2 mm - 6 mm, and the height of the groove is 1 mm - 2 mm.
[0005] Preferably, the plane of the groove of the infusion fixator forms an inclination angle of 4° - 10° with the horizontal plane.
[0006] Preferably, the sticky patch is made of non-woven fabric.
[0007] Preferably, the thickness of the fixing block is 4 mm - 5.8 mm.
[0008] Preferably, the notch is rectangular and one end coincides with the bottom surface of the groove.
[0009] Preferably, the total length of the fixing block is 38 mm - 45 mm.
[0010] The infusion fixator made by using the technical solution of the present invention maintains the optimal physiological infusion angle throughout the infusion process, and can assist the nursing staff to smoothly insert the needle into the blood vessel. At the same time, the adhesive design can prevent the needle from falling off easily, reducing the pain of repeated punctures for the patient. It effectively prevents the needle tip from adhering to the wall during infusion, or slipping out or piercing out of the blood vessel, and the pain, swelling and drug waste caused by the patient. It effectively prevents the liquid from soaking through and flowing into the subcutaneous tissue, preventing the occurrence of infections or other diseases. The lower adhesive design is novel and easy to use, and can also meet the needs of single-handed operation by medical staff in special cases. Description of the Drawings

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0017] The present invention provides an infusion fixator as Figures 1-4 shown, including a fixing block 1. One side surface of the fixing block 1 is inwardly provided with a groove, and the cross-section of the groove is triangular. A notch 3 communicating with the groove is linearly opened at the center position of the upper surface of the fixing block 1. The cross-section of the fixing block 1 is triangular. The fixing block 1 is composed of two trapezoidal blocks and a gradient block connected at the center. An adhesive 4 matching its shape and size is provided on the lower surface of the fixing block 1. The width of the notch 3 is 2 mm - 6 mm, and the height of the groove is 1 mm - 2 mm; the plane of the groove 2 of the infusion fixator forms an inclination angle of 4° - 10° with the horizontal plane; the adhesive 4 is made of non-woven fabric; the thickness of the fixing block 1 is 4 mm - 5.8 mm; the notch 3 is rectangular and one end coincides with the bottom surface of the groove; the total length of the fixing block 1 is 38 mm - 45 mm.
[0018] When in specific use: The infusion set is fixed and pasted in a pre-set manner before infusion. During use, insert the two wings of the infusion set needle into the grooves of the fixing block until the upper edges of the two wings touch the front closing part of the fixing block. Place the needle at the position of the gradient block connected in the center. After the infusion operation is carried out normally, tear the X-shaped sticker at the bottom from the left and right sides respectively and paste it on the hand.
[0019] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
