[0024] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0025] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0026] like Figure 1-3 As shown, a protective device for an indwelling needle comprises a connecting belt 1 made of cloth, a mounting ring 2 made of silicone, a connecting assembly, a transparent anti-skid film 3 made of flexible material and a limiting assembly. Notches 11 are provided at both ends of the connecting belt 1, and the two ends of the connecting belt 1 are detachably connected through the connecting assembly. The mounting ring 2 is fixedly sleeved on the middle part of the connecting belt 1, the transparent anti-skid film 3 covers the bottom opening of the mounting ring 2, and is detachably connected to the bottom wall of the mounting ring 2 through the limiting assembly, so that the transparent anti-skid film 3 can be replaced, so that the protective device for the indwelling needle can be reused.

[0027] Specifically, the connecting belt 1 made of cloth can be easily bent and deformed to fit the patient's body surface; the mounting ring 2 made of silicone can provide a more stable structural support for the connection of the limiting component.

[0028] In one embodiment, the limiting component can be a strip of adhesive, which is arranged on the bottom wall of the mounting ring 2 along its circumference. The user can adhere the edge of the transparent anti-slip film 3 to the adhesive so that the transparent anti-slip film 3 covers the bottom opening of the mounting ring 2 (not shown in the drawings).

[0029] In this embodiment, taking the indwelling needle located on the back of the hand as an example, when in use, the medical staff first turns the bottom wall of the mounting ring 2 toward the back of the patient's hand, so that the transparent anti-slip film 3 covers the puncture part of the indwelling needle, and at the same time, wraps the two ends of the connecting belt 1 around the palm of the patient. At this time, the patient's thumb can be extended through the notch 11 to facilitate the movement of the thumb, and then the two ends of the connecting belt 1 are connected through the connecting component, so that the connecting belt 1 is tied to the palm, and the puncture part of the indwelling needle is covered by the deformation of the transparent anti-slip film 3. The medical staff can observe the indwelling needle through the transparent anti-slip film 3. Under the action of the electrostatic force on the surface of the transparent anti-slip film 3, the transparent anti-slip film 3 will adhere to the puncture part of the indwelling needle over a large area, thereby limiting the swing of the puncture part of the indwelling needle, improving the firmness of the indwelling needle when it is adhered to the body surface, and avoiding the indwelling needle from being easily offset or even loosened when squeezed by foreign objects, thereby improving the use experience of the indwelling needle.

[0030] In one embodiment, the area of ​​the transparent anti-slip film 3 can cover the palm and part of the arm at the same time, so as to cover the heparin cap connected to the puncture part of the indwelling needle, thereby improving the firmness of the heparin cap attached to the arm and preventing the heparin cap from being squeezed and shifted by foreign objects.

[0031] Furthermore, at least three limiting holes 21 are distributed circumferentially on the bottom wall of the mounting ring 2, the limiting holes 21 are blind holes, the transparent anti-skid film 3 covers the limiting holes 21, a plurality of limiting components are provided and are arranged one-to-one with the limiting holes 21, the limiting component includes a magnetic suction component 4, a magnet 5 and a limiting block 6, the magnetic suction component 4 is arranged on the bottom wall of the corresponding limiting hole 21, the magnet 5 is arranged inside the limiting block 6, so that the limiting block 6 can be used to protect the magnet 5 to prevent the magnet 5 from falling after removal or being squeezed by foreign objects and easily damaged, the limiting block 6 can be slidably extended into the limiting hole 21, and the transparent anti-skid film 3 is partially clamped in the limiting hole 21, so that the magnet 5 is adsorbed with the magnetic suction component 4, thereby utilizing the magnetic suction effect to make the limiting Block 6 is fixedly clamped in the limiting hole 21, fixing the multi-angle of the transparent anti-slip film 3 and stretching the transparent anti-slip film 3. Since the transparent anti-slip film 3 will undergo adaptive deformation when covering the indwelling needle, the shape of the transparent anti-slip film 3 will be fixed after being fixed for a period of time. If the user or the use site is changed subsequently, the original transparent anti-slip film 3 may be difficult to adapt to the contour of the new indwelling needle. At this time, the medical staff can remove the limiting blocks 6 one by one, release the limiting of the original transparent anti-slip film 3, remove the original transparent anti-slip film 3, and then just repeat the operation of magnetically clamping the limiting blocks 6 to install a new transparent anti-slip film 3 on the bottom wall of the mounting ring 2 for the reuse of the indwelling needle protection device.

[0032] Furthermore, the limiting hole 21 is a circular hole, the shape of the limiting block 6 is adapted to the limiting hole 21, and the diameter of the limiting block 6 is smaller than the diameter of the limiting hole 21, so as to reduce the difficulty of the limiting block 6 being inserted into the limiting hole 21, and at the same time, a space for accommodating the transparent anti-slip film 3 is reserved between the inner wall of the limiting hole 21 and the side wall of the limiting block 6.

[0033] Furthermore, four limiting holes 21 are provided and evenly distributed on the bottom wall of the mounting ring 2 along the circumference thereof, so that the four corners of the transparent anti-slip film 3 can be fixed by snapping four limiting blocks 6 with the four limiting holes 21 one by one, thereby improving the installation stability of the transparent anti-slip film 3.

[0034] Furthermore, an avoidance opening 22 connected to the limit hole 21 is provided at the bottom end of the inner wall of the mounting ring 2. When the limit block 6 is inserted into the limit hole 21, its outward end will be flush with the bottom wall of the mounting ring 2. At this time, the user can contact the side wall of the limit block 6 through the avoidance opening 22 so that the user can press the limit block 6 with his fingers to release the adsorption effect of the magnet 5 and the magnetic suction part 4, and take the limit block 6 out of the limit hole 21, thereby reducing the difficulty of disassembling the limit block 6.

[0035] Furthermore, an anti-slip structure is provided on the side wall of the limit block 6 to increase the friction resistance between the fingers and the limit block 6 when pinching or moving the limit block 6, so that the limit block 6 is easier to pick up.

[0036] Furthermore, the indwelling needle protection device also includes a transparent protective sheet 7 made of flexible material, which is fixedly covered on the top opening of the mounting ring 2. After wearing the indwelling needle protection device, the user can observe the indwelling needle through the transparent protective sheet 7 and the transparent anti-slip film 3. At the same time, the transparent protective sheet 7 can also block foreign objects to prevent foreign objects from directly contacting the transparent anti-slip film 3, thereby reducing the impact of bumps on the indwelling needle, thereby ensuring that the indwelling needle is firmly attached to the patient's body surface.

[0037] Furthermore, the connecting strap 1 is made of elastic fabric so that the connecting strap 1 can be deformed and stretched when worn to adapt to wearing on parts of different sizes (such as palms, arms, legs, etc.), while improving the fit between the connecting strap 1 and the wearing part and improving the wearing stability.

[0038] Furthermore, the connecting component is a Velcro, which includes a hook surface 8 and a fleece surface 9. The hook surface 8 and the fleece surface 9 are respectively arranged at both ends of the connecting belt 1, so that the two ends of the connecting belt 1 can be quickly bonded through the hook surface 8 and the fleece surface 9, making the connection of the two ends of the connecting belt 1 more convenient.

[0039] Furthermore, the connecting component is a buckle, which includes a male buckle and a female buckle, which are respectively arranged at the two ends of the connecting belt 1 (not shown in the drawings), and the two ends of the connecting belt 1 can be quickly connected by plugging the male buckle and the female buckle.

[0040] Obviously, the embodiments described above are only some embodiments of the utility model, rather than all embodiments. The preferred embodiments of the utility model are given in the accompanying drawings, but they do not limit the patent scope of the utility model. The utility model can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the utility model more thorough and comprehensive. Although the utility model is described in detail with reference to the aforementioned embodiments, for those skilled in the art, it is still possible to modify the technical solutions recorded in the aforementioned specific implementation methods, or to replace some of the technical features therein with equivalents.
