Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a venous infusion tube fixing device. Background Art

[0002] Intravenous tubing, also known as venous access, is a tool that helps deliver medication, blood, or nutrients directly into a patient's blood vessels. It is commonly used in various clinical procedures, including surgical infusions and blood transfusions. However, if the intravenous tubing or needle becomes dislodged during treatment, it can lead to infection or painful re-insertion. Therefore, securing the intravenous tubing and needle during treatment is crucial.

[0003] Currently, adhesive tape is mostly used to directly stick the infusion tube and needle to the skin. However, the infusion tube will be pulled during the patient's activities, and the adhesive tape is difficult to offset the pulling force, causing the infusion tube to pull the needle off.

[0031] See also Figure 1-7 The utility model provides a technical solution: a device for fixing an intravenous infusion tube, comprising a support body 15 for laying an infusion tube 14, both ends of the support body 15 are fixedly connected to a strap 1, and the two ends of the support body 15 are fixed to the patient's arm and hand respectively by the two straps 1, and an upwardly protruding hollow tube 2 is fixedly connected to the middle of the top surface of the support body 15, and locking components are provided on both sides of the hollow tube 2 near the two ends of the support body 15, and the two locking components are fixedly connected to the support body 15.

[0032] In this solution, for intravenous infusion on the back of a patient's hand, the support 15 can be firmly fixed to the patient's arm by tying the two straps 1 to the patient's arm and hand respectively. The support 15 is made of a hard material, and both the support 15 and the straps 1 are transparent, making it easier for medical staff to observe whether the needle has fallen off.

[0033] During use, the two straps 1 are tied to the patient's arm and hand, respectively, with the strap 1 tied to the patient's hand fitting the needle insertion site on the back of the patient's hand. The infusion tube 14 is then wrapped around the hollow tube 2 twice, and the infusion tubes 14 extending from both sides of the hollow tube 2 are fixed to the support 15 via a locking assembly. When the patient moves, the friction between the infusion tube 14 and the hollow tube 2 limits the stretching distance of the infusion tube 14, preventing it from being pulled on the needle. Compared to existing technologies, when the patient moves, the infusion tube 14 is restricted from stretching at the hollow tube 2, reducing the risk of the needle falling off.

[0034] In this embodiment: the locking assembly includes a first clamping block 3 and a second clamping block 4, the bottom of the first clamping block 3 is fixedly connected to the top surface of the support body 15, one end of the second clamping block 4 is hinged on the first clamping block 3, and the other end is penetrated by a bolt 5, and the second clamping block 4 is detachably connected to the first clamping block 3 by the bolt 5.
