[0002] Intravenous infusion is a method of injecting a large amount of sterile liquid, electrolytes, and drugs into the body through the veins using the principles of atmospheric pressure and liquid static pressure. During the intravenous infusion process, it is all done manually, which is time-consuming and laborious.

[0003] Therefore, the existing public patent (publication number CN 211244944 U) discloses an early warning device for intravenous infusion, which relates to the field of medical device technology, and specifically includes a shell, a through hole is opened on the lower surface of the shell, a contact alarm button is installed at the center position of the inner upper surface of the shell, the inner upper surface of the shell is fixedly connected to two symmetrically arranged fixing columns, the outer side surfaces of the fixing columns are fixedly connected to a ring sleeve 1, a cylindrical block is arranged at the inner center position of the shell, and the outer side surface of the cylindrical block is fixedly connected to a ring sleeve 2. When the liquid medicine in the infusion bottle is about to be infused, the utility model can make the alarm light flash and the alarm speaker sound, to warn the medical staff and remind the medical staff that the liquid medicine is about to be replaced, thereby avoiding the situation where the medical staff neglects observation and causes danger to the patient, thereby improving the safety of intravenous infusion, and also avoiding the need for medical staff to always observe the capacity of the liquid medicine in the infusion bottle, thereby reducing the labor intensity of medical staff.

[0004] The above device is based on the contact alarm principle as a warning judgment signal, but in actual environments, the sound alarm will affect the rest of the patients, or in a noisy environment, the sound alarm often fails to attract the attention of medical staff, or it is inconvenient for medical staff to find patients based on the sound, especially during pediatric infusion, because the height of the children's infusion bottle is relatively low, when an alarm occurs, it is not convenient for doctors to quickly find the location of the infusion bottle, and for safety reasons, existing hospitals have gradually begun to use soft bags to hold liquid medicine. The existing warning device for intravenous infusion cannot hang the soft bag and lacks versatility. To this end, the utility model proposes a warning device for intravenous infusion to achieve improvements on the above problems. Utility Model Content

[0022] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] See also Figure 1-4 , in the figure: This embodiment is a preferred implementation of the technical solution, an early warning device for intravenous infusion, comprising a substrate 1; a hook 2 is fixed to the middle position of the front of the substrate 1, a horizontal liquid level gauge 3 is fixed to the middle position of the side of the hook 2, and a horizontal scale line is arranged in the middle position of the horizontal liquid level gauge 3, the horizontal liquid level gauge 3 is a transparent structure, and the height of the liquid level inside the horizontal liquid level gauge 3 is the same as the height of the horizontal scale line, a weighing sensor 4 is fixed to the lower end of the hook 2, a lampshade 5 is movably connected to the lower side of the weighing sensor 4, an indicator light is embedded in the side of the lampshade 5, the indicator light and the weighing sensor 4 are connected to a controller 9, and the controller 9 is fixed to the front edge of the substrate 1;

[0024] It should be noted that the intravenous infusion warning device involved in the present application is mainly used for pediatric infusion. The height of the infusion bottle for children is relatively low. When an alarm occurs, it is not convenient for the doctor to quickly find the position of the infusion bottle. The warning device uses weighing as an early warning judgment method, and cooperates with the early warning indication of the indicator light to facilitate medical staff to quickly find the position of the infusion bottle when replacing the infusion bottle. In order to ensure the accurate reading of the weighing sensor 4, a horizontal liquid level meter 3 is provided to assist in judging whether the weighing sensor 4 is in a horizontal state, so as to avoid reading errors caused by the tilted position of the weighing sensor 4. In specific use, when it is an infusion bottle, the infusion bottle can be hung on the guardrail 6 and the arc support The bracket 7 and the limit ring 8 are in the hanging structure, and then the liquid level of the horizontal liquid level gauge 3 is observed. If the liquid level is consistent with the horizontal scale line, the weighing sensor 4 is in the horizontal state. If not, the angle of the substrate 1 is adjusted, and then the angle of the weighing sensor 4 is adjusted until it is in the horizontal state. As the infusion progresses, the liquid in the infusion bottle gradually decreases. When the warning value is reached, the indicator light is on, and the controller 9 transmits the warning signal to the management end. The medical staff replaces the infusion bottle according to the signal displayed on the management end. On the contrary, when it is an infusion bag, it can be hung on a support rod on one side of the arc bracket that is not sealed. Both infusion bottles and infusion bags can be placed to improve practicality.

[0025] Among them Figure 1 As shown, a guardrail 6 is fixed to the lower side edge of the lampshade 5, an arc-shaped bracket 7 is fixed to the bottom of the guardrail 6, and a limit ring 8 is fixed to the bottom of the arc-shaped bracket 7; the guardrail 6 is hollowed out, and the limit ring 8 cooperates with the bottle mouth of the infusion bottle;

[0026] It should be noted that the hanging structure composed of the guardrail 6, the arc-shaped bracket 7 and the limit ring 8 is used for the hanging limit of the infusion bottle. The guardrail 6 and the arc-shaped bracket 7 are both in a semi-open state, which is convenient for taking and placing the infusion bottle. The hollow guardrail 6 structure is convenient for directly observing the remaining liquid amount in the infusion bottle on site. The arc-shaped bracket 7 is in a semi-open state, which is also convenient for hanging the infusion bag.

[0027] Among them Figure 2 and Figure 3 As shown, a mounting seat 10 is fixed on the back of the base plate 1, and a shaft is connected inside the mounting seat 10, a side plate 11 is fixed to the outer end of the shaft, and a mounting plate 12 is fixed to the tail of the side plate 11; a fastening knob 13 is provided at the outer end of the side plate 11, and the inner end of the fastening knob 13 passes through the side plate 11 and the shaft;

[0028] It should be noted that: the mounting seat 10 is movably connected to the side plate 11 via a shaft, and under the action of the tightening knob 13, the mounting seat 10 and the side plate 11 maintain a fixed relative position, and the mounting plate 12 fixed at the tail of the side plate 11 is used to fix the position of the entire device. When adjusting the position of the mounting seat 10, loosen the tightening knob 13, and then adjust the relative angle between the mounting seat 10 and the side plate 11 until the horizontal liquid level gauge 3 is in a horizontal state, and then fix the position of the mounting seat 10 by tightening the knob 13.

[0029] Among them Figure 4 As shown, the controller 9 has a built-in data processing unit, an execution unit and a communication unit, and the data processing unit is connected to the execution unit and the communication unit; the communication unit interacts with the management end data, the execution unit is connected to the indicator light, and the data processing unit is connected to the weighing sensor 4;

[0030] It should be noted that: when the controller 9 is running, the weighing data of the weighing sensor 4 is transmitted to the inside of the controller 9 in real time, received by the data processing unit and analyzed and processed. As the liquid in the infusion bottle gradually decreases, when the warning value is reached, the data processing unit transmits the warning information to the management end and controls the indicator light to turn on through the execution unit. The above principle is a relatively mature technology at present, and this application does not make any further restrictive description of its principle.
