[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The utility model embodiment discloses a fixing and protecting device for an indwelling needle.

[0026] The utility model provides Figure 1-4 The shown in Figure 1 is a fixing and protecting device for an indwelling needle, comprising a supporting portion 1 and a plurality of finger sleeves 2. A plurality of rotating rods 3 are rotatably provided on one side of the supporting portion 1, and the other end of each rotating rod 3 is fixedly connected to a connecting plate 4, and each finger sleeve 2 is fixedly provided on the side wall of the corresponding connecting plate 4. A slot is provided on the side of the supporting portion 1, and a fixing rod 5 is fixedly provided inside the slot. A slider 6 is movably sleeved on the rod wall of the fixing rod 5, and an L-shaped rod 7 is rotatably connected to the side wall of the slider 6. A protective cover 8 is fixedly connected to the other end of the L-shaped rod 7, and a limiting mechanism is provided on the side of the protective cover 8 away from the L-shaped rod 7. A plurality of limiting grooves are provided on one side of the supporting portion 1, and each limiting groove matches the limiting mechanism. By utilizing the limiting mechanism, the position of the protective cover 8 can be fixed by plugging the limiting mechanism into the corresponding limiting groove, and the position of the protective cover 8 can be adjusted so as to cover and protect the indwelling needle according to the actual position of the needle.

[0027] like Figure 4 As shown, the limiting mechanism includes a limiting rod 9 and two fixing plates 10. The two fixing plates 10 are fixedly arranged on the side walls of the protective cover 8 and have through holes inside. The limiting rod 9 is movably inserted into the two through holes and movably connected with the corresponding limiting grooves. The rod wall of the limiting rod 9 is provided with a stable plug-in mechanism. By plugging the setting limiting rod 9 with the corresponding limiting groove, the position of the protective cover 8 can be fixed, thereby preventing the protective cover 8 from shaking and compressing the indwelling needle.

[0028] like Figure 4As shown, the stable plug-in mechanism includes a push plate 11 and a spring 12. The push plate 11 is fixedly sleeved on the rod wall of the limiting rod 9. The spring 12 is fixedly arranged between the push plate 11 and the corresponding fixed plate 10 and is movably plugged with the rod wall of the limiting rod 9. By utilizing the set push plate 11 and spring 12, the push plate 11 can be squeezed by the elastic force of the spring 12, so that the limiting rod 9 can maintain a stable plug-in with the corresponding limiting groove.

[0029] like Figure 4 As shown, one end of the limiting rod 9 away from the supporting portion 1 is fixedly connected with a pull ring 13 . The setting of the pull ring 13 can be used to facilitate pulling the limiting rod 9 , thereby adjusting the position of the protective cover 8 .

[0030] like Figure 1-2 and Figure 4 As shown, the protective cover 8 is a transparent acrylic plate. The protective cover 8 made of the transparent acrylic plate can facilitate observation of the state of the indwelling needle.

[0031] like Figure 1-3 As shown, each finger sleeve 2 is a rubber sleeve. The rubber sleeve can effectively ensure the comfort of each finger sleeve 2 during the contact process with the finger.

[0032] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
