[0021] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.

[0023] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0024] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0025] like Figure 1-5 The intravenous infusion fixing device shown comprises an elastic portion (1) and a gripping portion (2), wherein the gripping portion (2) comprises a straight palm plate (201), wherein the palm plate (201) is made of plastic, because when plastic has a certain thickness, it will have a certain hardness and will not be easily bent or deformed, and the shape of the palm plate 201 is similar to the shape of the palm, which is roughly rectangular, and a heat dissipation groove (203) is also provided on the palm plate 201 to facilitate the dissipation of sweat on the palm, and a gripping handle (202) is provided at one end of the palm plate (201), wherein the gripping handle (202) is cylindrical and is a portion that can be curled and gripped by fingers other than the thumb, and the gripping handle (202) is usually made of skin-friendly silicone material and is provided with a load-reducing cavity (204) to reduce consumables and reduce deadweight, thereby achieving better lightweight.

[0026] The thickness of the palm plate (201) is smaller than the radius of the handle (202), and the outer side surface of the handle (202) is flush with the side surface of the palm plate (201) with the largest width, so the handle 202 and the palm plate 201 form a fist shape, and the outer side surface fits the palm of the hand in a relaxed state very well. A finger ring (205) is provided at the tangent point between the palm plate (201) and the handle (202) for allowing fingers other than the thumb to pass through. The plane where the finger ring (205) is located is perpendicular to the outer side surface of the handle (202), and the axis of the finger ring (205) is parallel to the palm plate (201). Because the finger ring 205 is usually located in the middle of the handle 202, it is most comfortable to let the middle finger pass through in most cases.

[0027] The elastic part (1) is in the shape of a strip and has high flexibility. The two ends of the elastic part (1) are fixedly connected to one end of the palm plate (201) away from the handle (202). Specifically, the palm plate (201) is provided with a configuration sink groove (206) on a pair of opposite sides, and the configuration sink groove (206) is away from the handle (202). The two ends of the elastic part (1) are respectively fixedly connected in the configuration sink groove (206), and are usually fixed by using a curing glue. The elastic part (1) can be made of a material with good elasticity and toughness such as rubber or silicone, and a ventilation hole (101) is provided on the elastic part 1 to facilitate ventilation of the skin covered by the elastic part 1 and reduce the probability of sweating when it is hot. The elastic part (1) is usually wrapped with a nylon braided layer, which can follow the elastic part 1 to deform in length and width.

[0028] Working principle: When in use, the hand of the infusion subject passes through the elastic part 1, the middle finger passes through the finger ring 205, and the four fingers hold the handle 202. At this time, the palm fits against the palm plate 201, and the end of the palm plate 201 presses against the root of the palm, that is, the front end of the forearm. The wrist is restricted and the range of rotation is greatly reduced. Then the infusion tube is also passed through the elastic part 1 and pressed between the back of the hand and the elastic part 1, and the needle operation can be performed. After the injection, it can be simply fixed with medical tape. Since the infusion tube is pressed and in close contact with the skin, it has a large contact friction. Therefore, even if the infusion tube is accidentally pulled, a large force will not be transmitted to the needle, causing the needle to fall off or bend, which can better protect the infusion subject.

[0029] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought. The scope of protection claimed by the present application is defined by the attached claims and their equivalents.
