Because more than one bottle is needed to be replaced during transfusion, whether the anti-slip assembly 6 is convenient to disassemble or not is also considered between the corresponding anti-slip assembly 6 and the bottle cap of the transfusion bottle, and when the anti-slip assembly 6 is required to be disassembled on the bottle cap, the two clamping rods 62 are required to be opened, and as no part suitable for being held by hand is arranged on the clamping rods 62, the clamping rods 62 are inconvenient to open; the pulling piece 64 is arranged at one side of the top of the clamping rod 62, which is away from the bottle stopper puncture needle 2, and the pulling piece 64 is used for vertically pulling the clamping rod 62, so that the top ends of the two clamping rods 62 are far away from each other, and because the clamping rod 62 is an elastic rod, when the pulling piece 64 is pulled, the top ends of the clamping rods 62 are forced to open, and at the moment, the bottle cap can be conveniently sleeved into the anti-slip assembly 6 or pulled out from the anti-slip assembly 6;
specifically, the pulling member 64 is a collar for the finger to be sleeved, and the collar is disposed in a horizontal direction or a vertical direction; when the bottle cap is sleeved into the anti-slip component 6, a medical staff holds the infusion bottle by one hand, two fingers (such as thumb and index finger) of the other hand are respectively sleeved in a lantern ring, the two fingers (such as thumb and index finger) open the clamping rod 62 with force towards the outer side, the bottle plug puncture needle 2 moves towards the bottle cap direction, the bottle cap enters the plurality of clamping rods 62, the bottle plug puncture needle 2 punctures into the bottle plug, the force applied to the lantern ring is released, under the action of the elasticity of the clamping rod 62, the clamping teeth 63 return, the bottle cap is wrapped in the area surrounded by the supporting plate 61, the clamping rod 62 and the clamping teeth 63, and the connection and the fixed installation of the bottle plug puncture needle 2 and the bottle cap are realized; meanwhile, the method can also be referred to, after the clamping rod 62 is opened by two fingers (such as thumb and index finger) towards the outside, the bottle stopper puncture needle 2 is moved back to the bottle cap direction, so that the bottle cap is separated from the clamping rods 62, and the anti-slip assembly 6 and the infusion bottle cap are detached.
Referring to fig. 1-2 of the specification, the cross section of the latch 63 is a right triangle, the top surface is an inclined surface, and the bottom surface is a horizontal surface; when the anti-slip assembly 6 is mounted on the bottle cap, the top surface edge of the bottle cap contacts the top surface of the latch 63 firstly, and because the top surface of the latch 63 is an inclined surface and the clamping rod 62 is an elastic rod, when the bottle cap continues to squeeze the latch 63, the bottle cap moves along the inclined surface of the top of the latch 63, and at the moment, the latch 63 is squeezed to open the clamping rod 62 until the tip of the latch 63 contacts with the side surface of the bottle cap, after the bottle cap completely enters the bottom of the latch 63, the clamping rod 62 rebounds, and the bottom surface of the latch 63 contacts with the rear end surface of the bottle cap to realize the connection and fixation of the bottle cap and the bottle plug puncture needle 2, so that the top surface of the latch 63 is the inclined surface, and the bottle cap, the anti-slip assembly 6 and the bottle plug puncture needle 2 are conveniently mounted.
Example 2
Based on embodiment 1, referring to fig. 3-5, the inventor finds that the thicknesses of the bottle caps used by infusion bottles of different manufacturers or different specifications are different, if the length of the clamping rod 62 is fixed, the connection and fixation of the anti-slip component 6 and the bottle cap cannot be realized if the thickness of the bottle cap is larger than the distance between the bottom surface of the clamping tooth 63 and the top surface of the supporting plate 61, and if the thickness of the bottle cap is smaller than the distance between the bottom surface of the clamping tooth 63 and the top surface of the supporting plate 61, after the bottle cap is wrapped in the area enclosed by the supporting plate 61, the clamping rod 62 and the clamping tooth 63, a certain degree of activity still exists in the vertical direction of the bottle cap relative to the bottle cap, and the activity degree can lead to the bottle cap puncture needle 2 to move downwards as a whole when the infusion tube 1 is pulled by external force, so that the liquid inlet is blocked by rubber bottle cap and even the bottle cap puncture needle 2 is separated from the rubber bottle cap;
therefore, the best connection and fixation mode between the anti-slip component 6 and the bottle cap is as follows: after the bottle cap is wrapped in the area surrounded by the supporting plate 61, the clamping rod 62 and the clamping teeth 63, the top surface of the supporting plate 61 is contacted with the top surface of the bottle cap, and the bottom surface of the clamping teeth 63 is contacted with the bottom surface of the bottle cap, so that the bottle cap puncture needle 2 has no vertical movement degree relative to the bottle cap; referring to fig. 1-3, the clamping rod 62 includes a sleeve 621 and a telescopic rod 622, the sleeve 621 is fixedly mounted on the top surface of the supporting plate 61, the bottom end of the telescopic rod 622 extends into the sleeve 621 and can slide up and down in the sleeve 621, a fixing component for fixing the position of the telescopic rod 622 is disposed between the sleeve 621 and the telescopic rod 622, the clamping teeth 63 are fixedly mounted on one side of the top of the telescopic rod 622 facing the bottle stopper puncture needle 2, and the pulling member 64 is fixedly mounted on one side of the top of the telescopic rod 622 facing away from the bottle stopper puncture needle 2.
