[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The nursing indwelling needle holder is provided with a wedge block, a movable rod, a spring, a limit groove and a compression belt. First, the child's hand is placed on the top of the small hand plate, and the fixing plate is held to align the fixing plate with the mounting block. When the fixing plate is placed into the mounting block, the inclined surface on the wedge block is squeezed by the mounting block, so that the two wedge blocks are close to each other and squeeze the spring. After a period of time, when the wedge block moves to the position of the limit groove, the spring is reset and pushes the two wedge blocks away from each other. The wedge block is stuck in the limit groove to limit the compression belt, and the compression belt compresses the needle tube. The purpose of fixing the needle tube is achieved by quickly fixing the compression belt, abandoning the traditional tape fixing method, and the operation is more convenient and the work efficiency is improved.

[0013] 2. The nursing indwelling needle holder is provided with a placement slot, a winding roller, a coil spring and a compression belt. When the compression belt needs to be loosened, a finger is placed inside the limiting slot, and the two wedge blocks are squeezed to make them close to each other. At this time, the limiting slot does not limit the wedge block, and the coil spring resets to drive the winding roller to rotate, and the winding roller winds the compression belt until the compression belt is completely stored in the storage box. The coil spring resets to drive the winding roller to rotate to automatically wind the compression belt, and the compression belt is stored in the storage box to prevent the compression belt from affecting medical work and improve practicality.

DETAILED DESCRIPTION

[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] like Figure 1-4As shown, the utility model provides a technical solution: a nursing indwelling needle holder, including a small hand plate 1. Because the four corners of the small hand plate 1 are provided with rounded corners, the child can be protected to prevent the small hand plate 1 from scratching the child's skin. A plurality of mounting blocks 4 are fixedly connected to the top of the small hand plate 1, and a plurality of storage boxes 3 are fixedly connected to the top of the small hand plate 1. A connecting plate 15 is fixedly connected inside the storage box 3.

[0021] Two limit grooves 9 are provided on the mounting block 4. Because of the limit grooves 9, the limit grooves 9 provide operating space, which is convenient for the user to squeeze the wedge block 8 and improves the convenience of operation. A fixing plate 6 is provided inside the mounting block 4, and a plastic pad 2 is provided on the small hand plate 1. Because of the plastic pad 2, when the child puts his hand on the plastic pad 2, the plastic pad 2 is designed as plastic and the material is soft, thereby improving the comfort of the child. One end of the movable rod 10 is fixedly connected with a round cap 11, and one end of the winding roller 13 is fixedly connected with a coil spring 16 through the connecting plate 15. Because of the coil spring 16, the coil spring 16 makes the clamping belt 5 always in a clamped state, thereby improving the stability of the clamping belt 5 when fixing the needle tube, and the end of the coil spring 16 away from the winding roller 13 is fixedly connected to the connecting plate 15.

[0022] A fixed frame 7 is fixedly connected to the bottom of the fixed plate 6, and four movable rods 10 are slidably connected to the fixed frame 7. One end of two movable rods 10 is fixedly connected to a wedge block 8. Since the wedge block 8 is designed as an inclined surface, the mounting block 4 can push the wedge block 8 to move, so that the entire operation process proceeds smoothly. The wedge block 8 corresponds to the limit groove 9, and the clamping belt 5 is made of transparent material.

[0023] A spring 12 is sleeved on the movable rod 10 , a compression belt 5 is fixedly connected to the fixed plate 6 , a winding roller 13 is rotatably connected to one side of the connecting plate 15 , a placement groove 14 is opened on the winding roller 13 , and the compression belt 5 is arranged inside the placement groove 14 .

[0024] The working principle of the utility model is:

[0025] First, place the child's hand on the top of the small hand board 1, hold the fixing plate 6 and align the fixing plate 6 with the mounting block 4, and when the fixing plate 6 is placed inside the mounting block 4, the inclined surface on the wedge block 8 is squeezed by the mounting block 4, so that the two wedge blocks 8 are close to each other and squeeze the spring 12. After a period of time, when the wedge block 8 moves to the position of the limiting groove 9, the spring 12 is reset, pushing the two wedge blocks 8 away from each other, and the wedge block 8 is stuck on the limiting groove 9 to limit the compression belt 5, and the compression belt 5 compresses the needle tube;

[0026] When it is necessary to loosen the compression belt 5, place your finger inside the limiting groove 9 and squeeze the two wedge blocks 8 to make them close to each other. At this time, the limiting groove 9 does not limit the wedge block 8, and the winding spring 16 resets to drive the winding roller 13 to rotate. The winding roller 13 winds up the compression belt 5 until the compression belt 5 is completely stored in the storage box 3.
