DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] See also Figure 1 - Figure 7 An infusion alarm comprises an alarm body 2 installed on an infusion tube 1, an infusion bottle 3 is provided at the upper end of the infusion tube 1, a groove 301 is provided at the bottle mouth of the infusion bottle 3, a connecting frame 4 is connected to the back side of the alarm body 2, and a fixing component is connected to the end of the connecting frame 4 away from the alarm body 2, and the fixing component is connected to the bottle mouth of the infusion bottle 3.

[0027] like Figure 1 - Figure 7As shown, an infusion alarm in the utility model is similar to the existing infusion alarm structure, such as an infusion alarm of model NZL300. The main improvement of the utility model is that after the infusion alarm body 2 is fixed on the infusion tube 1, the alarm body 2 is connected and fixed to the infusion bottle 3, thereby indirectly improving the connection firmness between the infusion tube 1 and the infusion bottle 3, reducing the separation of the infusion tube 1 and the infusion bottle 3 when the infusion tube 1 is pulled, and improving the safety of infusion, such as Figures 1 to 7 As shown, when the infusion alarm in the utility model is in use, the alarm body 2 is installed on one end of the infusion tube 1 close to the infusion bottle 3, and then connected to the groove 301 at the bottle mouth of the infusion bottle 3 through the fixing component at the other end of the connecting frame 4, so that when the infusion tube 1 is inserted into the infusion bottle 3, the connection between the infusion bottle 3 and the alarm body 2 is used to provide a connection reinforcement between the infusion tube 1 and the infusion bottle 3, so that during the infusion, if there are children or accidents that cause the infusion tube 1 to be pulled, the connecting frame 4 provides a connection support between the alarm body 2 and the infusion bottle 3, so that the connection position where the infusion tube 1 is inserted into the infusion bottle 3 is not easy to fall off, thereby improving the safety of infusion and reducing the medical risks occurring during the infusion process.

[0028] like Figure 1 - Figure 7 As shown, the connecting frame 4 is an L-shaped structure, and one end of the horizontal rod of the connecting frame 4 is fixedly connected to the alarm body 2, and one end of the vertical rod is connected to the fixing assembly. The connecting frame 4 is designed to be L-shaped, so that the infusion tube 1 connected to the alarm body 2 is located directly below the infusion bottle 3 as much as possible, reducing the bending of the infusion tube 1 and the infusion bottle 3 connection position, ensuring the normal flow of the infusion.

[0029] like Figure 1 - Figure 7As shown, the fixing assembly includes a strap 5 and a U-shaped fixing ring 6, which are respectively located on both sides of the end of the connecting frame 4 away from the alarm body 2, and are respectively fixedly connected to the two sides of the connecting frame 4, the end of the strap 5 away from the connecting frame 4 surrounds the groove 301 and passes through the ring of the U-shaped fixing ring 6, and a fastener is connected to the side of the connecting frame 4 away from the infusion bottle 3, the fastener is located between the strap 5 and the U-shaped fixing ring 6 and close to the U-shaped fixing ring 6, and a plurality of slots 501 are provided on one end of the strap 5 close to the U-shaped fixing ring 6 and close to the side of the connecting frame 4, and the fastener is slidably connected to the slot 501. When using the fixing assembly to connect the connecting frame 4 to the bottle mouth of the infusion bottle 3, the strap 5 on one side of the connecting frame 4 is wrapped around the groove 301 at the bottle mouth of the infusion bottle 3 and passed through the inner side of the U-shaped fixing ring 6 on the other side, thereby connecting and fixing the bottle mouth of the infusion bottle 3 to the connecting frame 4, and then using a fastener to connect to the slot 501 provided on the strap 5 passing through the U-shaped fixing ring 6, thereby fixing the strap 5 to prevent the strap 5 from loosening after being tied to the infusion bottle 3.

[0030] like Figure 5 - Figure 7 As shown, the fastener includes a sleeve 7, an insert rod 8 and an extrusion spring 9. The sleeve 7 is fixedly connected to the connecting frame 4, the insert rod 8 is slidably connected to the inner wall of the sleeve 7, a control hole 701 is penetrated through the side of the sleeve 7 away from the connecting frame 4, one end of the insert rod 8 penetrates the sleeve 7 and is slidably connected to the adjacent slot 501, the other end of the insert rod 8 is fixedly connected to the extrusion spring 9, and the other end of the extrusion spring 9 is fixedly connected to the inner wall of the sleeve 7. After the mouth of the infusion bottle 3 is tied and fixed with the strap 5, the extrusion spring 9 drives the insertion rod 8 to slide outward in the sliding sleeve 7, and inserts the end of the insertion rod 8 into the corresponding card slot 501, and at the same time, the other side of the strap 5 is pressed against the inner side of the U-shaped fixing ring 6, thereby completing the connection and fixation of the strap 5, and preventing the strap 5 from sliding outward from the inside of the U-shaped fixing ring 6 under force and falling off. When it is necessary to disassemble the connection between the connecting frame 4 and the infusion bottle 3, the insertion rod 8 is moved into the sliding sleeve 7 through the control hole 701, so that the insertion rod 8 is separated from the card slot 501 on the strap 5, thereby releasing the fixation of the strap 5. At this time, the strap 5 and the groove 301 at the mouth of the infusion bottle 3 can be separated from each other, and the connection and fixation between the connecting frame 4 and the infusion bottle 3 can be released.

[0031] like Figure 5 - Figure 7 As shown, a control block 10 is fixedly connected to one end of the plunger 8 close to the extrusion spring 9 and to one side close to the control hole 701, and the control block 10 is slidably connected to the control hole 701. When the plunger 8 is moved toward the inside of the sliding sleeve 7, the control block 10 can more conveniently control the movement of the plunger 8 inside the sliding sleeve 7.

[0032] like Figure 5 - Figure 7As shown, the control block 10 is fixedly connected to one end away from the insertion rod 8 with a push piece 11, and the push piece 11 is slidably connected to the connecting frame 4. When in use, the push piece 11 is pressed by a finger and slides to one side, so that the internal insertion rod 8 is retracted into the sliding sleeve 7 through the control block 10, thereby releasing the fixing of the binding belt 5, and facilitating the disassembly of the connecting frame 4 and the infusion bottle 3.

[0033] like Figure 5 - Figure 7 As shown, the push piece 11 covers the control hole 701. The push piece 11 covers the control hole 701, which can reduce the impurities such as dust from the outside from entering the sliding sleeve 7 through the control hole 701, thereby affecting the telescopic stability of the extrusion spring 9.

[0034] like Figure 4 - Figure 7 As shown, the side of the connecting frame 4 close to the infusion bottle 3 is fixedly connected with an arc-shaped stopper 12, and the side of the arc-shaped stopper 12 away from the connecting frame 4 is arc-shaped and abuts against the groove 301. When the bottle mouth of the infusion bottle 3 is tied to the connecting frame 4 using the strap 5, the arc-shaped stopper 12 abuts against the groove 301 of the bottle mouth of the infusion bottle 3, which can further improve the connection firmness between the infusion bottle 3 and the connecting frame 4.

[0035] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
