Problems solved by technology

[0003] Due to the slow speed of the infusion, the infusion volume is different, and the infusion time cannot be controlled
Infusion patients are prone to sleep during the long infusion process, especially at night or even in the middle of the night. When the injection in the infusion bag is about to be infused, if the dressing is not changed or the needle is not taken in time, blood reflux may occur. Serious conditions that may lead to the death of the infusion recipient

Embodiment approach 1

[0031] This embodiment provides an alarm device for preventing blood backflow during infusion, such as figure 1 As shown, it is mainly composed of a positioning mechanism 3, a first clamping support elastic sheet 1, a second clamping support elastic sheet 2, a first clamping conduction mechanism 4, a second clamping conduction mechanism 5, an alarm 6 and an internal Circuit composition, the first clamping support elastic thin plate 1 and the second clamping support elastic thin plate 2 are made of elastic materials; as figure 2 and 3 , the positioning mechanism 3 is mainly composed of a housing 301, a hollow shaft (not shown in the figure), a large vertebral gear 302, a small bevel gear 304, a chuck body 307 and three movable jaws 306, and the hollow shaft is vertically fixed on the housing In 301, the large bevel gear 302 is rotationally connected with the hollow shaft and is horizontally arranged in the housing 301 through the hollow shaft; the center of the large bevel ge...

Embodiment approach 2

[0037] This embodiment is a further improvement of Embodiment 1. The main improvement is that in Embodiment 1, due to the first hollow horizontal female bar 402 in the first clamping conduction mechanism 4 and the second clamping conduction mechanism 5 The length of the second hollow horizontal mother rod 502 is fixed. When it is necessary to use the infusion soft bag 8 with a larger size and wider width for infusion, even if all the liquid in the infusion soft bag 8 is discharged, the first hollow horizontal mother rod 402 and the second hollow mother rod 402 The first magnet 401 and the second magnet 501 at the two ends of the two hollow horizontal female bars 502 also cannot contact each other due to the isolation of the middle infusion soft bag 8, the internal circuit cannot be conducted, and the alarm 6 cannot play an alarm function. In this embodiment, the above situation can be effectively improved.

[0038] Specifically, in this embodiment, as Figures 7 to 9 , in the...

Embodiment approach 3

[0042] This embodiment is a further improvement of Embodiment 2. The main improvement is that, in Embodiment 2, the inner sides of the three movable claws 306 are in direct contact with the infusion tube mouth 801 of the soft infusion bag 8 . The material is relatively hard, and it is easy to pinch the infusion tube mouth 801; in order to avoid the occurrence of the above situation, in this embodiment, the inner contact arcs made of silicone material are respectively fixed on the inner sides of the opposite ends of the three movable claws 306. Disc 308, such as Figure 10 and 11 As shown, the inner contact arc disc 308 made of silica gel can effectively prevent the infusion tube port 801 from being scratched; the arcs of the three inner contact arc discs 308 are all set to 120°, so that the three inner contact arc discs 308 just form A circle has a certain stability and uniform force on the infusion tube port 801 .

[0043] In addition, the outer diameter of the infusion tub...

Abstract

The invention relates to the technical field of intravenous infusion, and discloses an alarm device for preventing blood return during infusion. A first clamping support elastic sheet (1) and a secondclamping support elastic sheet (2) are arranged to form an included angle with narrow bottom and wide top, the bottom ends of the two are fixed on a positioning mechanism (3), and the top ends are respectively fixed on a first clamping conduction mechanism (4) and a second clamping conduction mechanism (5) symmetrically disposed. First magnets (401) of the same polarity are fixed at two ends of the first clamping conduction mechanism, and second magnets (501) of the polarity different from that of the first magnets are fixed at two ends of the second clamping conduction mechanism. An alarm device (6) is disposed on the first clamping conduction mechanism or the second clamping conduction mechanism, and the alarm is connected to internal circuits of the first clamping conduction mechanismand the second clamping conduction mechanism through wires. Compared with the prior art, the alarm device can automatically remind a doctor and a patient that the injection is about to be infused, avoid the phenomenon of blood return and improve the infusion safety.

Description

technical field [0001] The invention relates to the technical field of intravenous infusion, in particular to an alarm device for preventing blood backflow during infusion. Background technique [0002] Intravenous infusion refers to the continuous and stable injection of large doses of liquid into the human body through veins to supplement the body fluids, electrolytes or provide nutrients for the infusion, so as to make the patient recover quickly; in the medical work, infusion is very common , usually the injection is hung upside down on a water hanger with a certain height, and then injected into the human body through a hanging needle; [0003] Because the speed of infusion is relatively slow, the volume of infusion is different, and the time of infusion cannot be controlled. Infusion patients are prone to sleep during the long infusion process, especially at night or even in the middle of the night. When the injection in the infusion bag is about to be infused, if the...
