[0036] Two clamping parts are equipped with elastic support for limiting two clamping parts relative to the distance apart.

[0037] By setting two clamping parts on installation strip 1, two positions of infusion tube 8 are clamped by two clamping parts, and when the elastic support is naturally stretched, the length dimension of infusion tube 8 between two clamping points is adjusted to be greater than the distance dimension between two clamping parts, when infusion tube 8 is subjected to external tension, two clamping parts are relatively far away, so that infusion tube 8 between two clamping strips is stretched straight, the length of infusion tube 8 is increased, to weaken the tension of infusion tube 8, reduce the risk of secondary injury to the patient's body caused by the needle on infusion tube 8.

[0038] In the embodiment: two clamping parts are the same structure, and each include base 2 connected with installation strip 1 and pressing block 3 for clamping infusion tube 8;

[0039] One end of pressing block 3 is hinged with one end of base 2, and the plane of rotation track is perpendicular to installation strip 1, and the other end of pressing block 3 is detachably connected with the other end of base 2.

[0040] By hingedly connecting one end of the pressing block 3 with one end of the base 2 and detachably connecting the other end of the pressing block 3 with the other end of the base 2, the infusion tube 8 is facilitated to be installed and dismounted, and the fastening device can be dismounted from the infusion tube 8 after the infusion is completed, so that the fastening device is reusable and economical and practical, since most medical infusion tubes 8 are disposable products.

[0041] In the embodiment, the base 2 is provided with a semicircular column-shaped notch 4 on a plane facing away from the mounting strip 1, and the pressing block 3 is provided with a semicircular column-shaped notch 4 on a plane facing the base 2, and the notch 4 on the base 2 and the notch 4 on the pressing block 3 are spliced to form a circular through hole along the length direction of the mounting strip 1.

[0042] The circular through hole formed by splicing the two notches 4 has a diameter matched with that of the infusion tube 8, and the infusion tube 8 is embedded in the notch 4, so as to reduce the risk of the medicine in the infusion tube 8 being squeezed and cut off, and enable the medicine in the infusion tube 8 to smoothly enter the patient's vein.

[0043] In the embodiment, the notch 4 is provided with a semicircular ring-shaped rubber pad 41, and the outer circular surface of the rubber pad 41 is fixedly connected with the inner circular surface of the notch 4.

[0044] The rubber pad 41 is provided, and the rubber pad 41 is in extrusion contact with the infusion tube 8, so that the rubber pad 41 is deformed when an external force is applied, so as to further reduce the risk of the medicine in the infusion tube 8 being squeezed and cut off; meanwhile, the inner circular surface of the rubber pad 41 is in full contact with the outer circular surface of the infusion tube 8, so that the rubber pad 41 and the infusion tube 8 have a large friction force, so as to limit the movement of the infusion tube 8 on the clamping part.

[0045] In the embodiment, the base 2 is provided with a threaded hole 21 on a plane facing away from the mounting strip 1 at one end away from the hinge center line, the pressing block 3 is rotatably connected with a bolt 31 at one end away from the hinge center line, and the threaded end of the bolt 31 is inserted into the threaded hole 21 and connected through threaded cooperation.

[0046] The threaded end of the bolt 31 is inserted into the threaded hole 21 and the bolt 31 is rotated, so that the threaded end of the bolt 31 is connected with the threaded hole 21 through threaded cooperation, so as to limit the rotation and opening of the pressing block 3, and the pressing block 3 and the base 2 stably clamp the infusion tube 8, which is simple and convenient to operate.

[0047] In the embodiment, the mounting strip 1 is provided with a sliding groove 11 extending towards the length direction of the mounting strip 1 on a plane facing the base 2, and a sliding block 12 is slidably connected in the sliding groove 11.

[0048] One end of the sliding block 12 protrudes out of the opening of the sliding groove 11 and is fixedly connected with the base 2 in one of the clamping parts, and the base 2 of the other clamping part is fixedly connected with the mounting strip 1.

[0049] By setting a slider 12 in the groove 11 and sliding it in fit, and fixing the slider 12 to the base 2 in one of the clamping parts, the purpose of one of the clamping parts can slide along the length direction of the mounting strip 1 is achieved.

[0050] In this embodiment: hooks 22 are fixedly connected to both bases 2, and the elastic support is a rubber band 5, which is sleeved on the two hooks 22.

[0051] Two hooks 22 are located on the same side of the two bases 2. The openings of the two hooks face away from each other and towards the two ends of the mounting strip 1. By looping the rubber band 5 onto the two hooks 22, a relatively converging pulling force is provided to the two clamping parts. The rubber band 5 can be removed from the hooks 22 for easy replacement, so that the rubber band 5 can continuously and stably provide a pulling force for the two clamping parts to move in opposite directions.

[0052] In this embodiment: a limiting block 6 is provided between the two clamping parts, the limiting block 6 is connected to the mounting strip 1, and the slider 12 abuts against the limiting block 6 when the rubber band 5 is in a naturally extended state.

[0053] By setting a limiting block 6 on the mounting strip 1 to restrict the slider 12 from sliding the corresponding clamping part towards the other clamping part, and when the rubber band 5 is in a naturally extended state, the slider 12 abuts against the limiting block 6 to restrict the rubber band 5 from naturally sliding off the two hooks 22, so that the fastening device can stably perform buffering work.

[0054] In this embodiment: the slide groove 11 is provided with a lead screw 7 parallel to the mounting strip 1, and the two ends of the lead screw 7 pass through the two side walls of the slide groove 11 and extend out of the slide groove 11 and are rotatably engaged;

[0055] The limiting block 6 is connected in series with the lead screw 7 and is connected by a threaded connection.

[0056] The limiting block 6 is embedded in the slide groove 11, and the two sides of the limiting block 6 are respectively attached to the two sides of the slide groove 11 to restrict the free rotation of the limiting block 6. By setting the lead screw 7 and threading the limiting block 6 to the lead screw 7, the limiting block 6 can move along the axial direction of the lead screw 7, so as to adjust the minimum distance between the two clamping parts and to install rubber bands 5 of different lengths. Since the rubber band 5 may undergo plastic deformation under continuous tensile and contraction stress, that is, the rubber band 5 may grow after plastic deformation, which increases the risk of the rubber band 5 slipping off the hook 22. By rotating the lead screw 7, the lead screw 7 pushes the limiting block 6 and the slider 12 to slide in the slide groove 11, increasing the distance between the two clamping parts, that is, increasing the distance between the two hooks 22, so that the rubber band 5 is straightened again, thereby reducing the risk of the rubber band 5 slipping off naturally.

[0057] In this embodiment: the slider 12 is connected in series with the lead screw 7, and the slider 12 and the lead screw 7 slide in a sliding fit along the axial direction of the lead screw 7.

[0058] The slider 12 is rectangular in shape so that it can be embedded in the groove 11. The two sides of the slider 12 are respectively attached to the two sides of the groove 11 to restrict the free rotation of the slider 12. By connecting the slider 12 to the lead screw 7, the slider 12 is restricted from sliding out of the groove 11, so that the slider 12 slides in the groove 11 along the axis of the lead screw 7 with a single degree of freedom.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it.
