Problems solved by technology

In the existing infusion process, when sleeping or comatose patients undergo infusion, the patient's family members or nurses are required to take care of them. Due to the lowering of the liquid level in the infusion bottle, the probability of air in the bottle entering the infusion tube is greater, especially when the infusion is about to end. With the reduction of the cross-sectional area of ​​the lower end of the infusion bottle, the turbulence of the liquid in the bottle is intensified under the action of the rising air bubbles, and the air often enters the infusion tube with the liquid. After the air enters the blood, it is easy to cause air embolism, and even lead to sudden death of the patient in severe cases. In addition, in the existing infusion process, the infusion speed is greatly affected by the hydraulic pressure in the bottle, and it is easy to appear that the infusion process is not smooth enough.

Embodiment 1

[0018] like figure 1 As shown, an infusion bottle automatic stop alarm device based on the principle of air pressure includes a housing 1, the upper end of the housing 1 is open, and a movable plate 2 is connected to the sliding seal in the housing 1. It should be noted that the movable plate 2 The gravity between the movable plate 2 and the housing 1 is balanced, so that the movable plate 2 can be suspended in any position in the housing 1. The lower end of the housing 1 is fixedly connected with the exhaust pipe 3, and the lower end of the movable plate 2 The side wall is provided with a sealing groove 4 corresponding to the exhaust pipe 3, and the end of the exhaust pipe 3 away from the housing 1 is fixedly connected with a joint 5, and the other end of the joint 5 is connected with the infusion bottle through a disposable air guide tube, and the exhaust The pipe 3 is fixedly connected with a one-way valve 6, and the housing 1 is provided with an alarm mechanism. Specifical...

Embodiment 2

[0021] like figure 2 As shown, the difference between this embodiment and Embodiment 1 is that the alarm mechanism includes a second alarm 10 fixedly connected to the outer wall of the housing 1, the housing 1 is cylindrical, and the housing 1 is covered with a magnetic Ring 11, the upper end of the second alarm 10 is provided with a trigger mechanism that matches the magnetic ring 11, it is worth mentioning that the second alarm 10 can adopt the same model as the first alarm 9, the second alarm 10 It is arranged on the outside of the housing 1, which can further improve the alarm effect of the second alarm 10. The movable plate 2 is made of magnetic material, and the magnetic ring 11 is attracted to the opposite poles of the movable plate 2. The outer wall of the housing 1 is provided with a coefficient of friction The resistance layer 12 changes from large to small from top to bottom. It should be noted that the resistance layer 12 is different friction grooves provided on ...

Abstract

The invention belongs to the field of medical devices, in particular to an infusion bottle automatic stop alarm device based on the pneumatic principle. The infusion bottle automatic stop alarm devicecomprises a housing. The housing has an open upper end. A movable plate is connected in a slidable sealing manner in the housing. An exhaust pipe is fixedly connected to the lower end of the housing.A sealing groove corresponding to the exhaust pipe is arranged at the lower side wall of the movable plate. The exhaust pipe is fixedly connected with a joint at an end thereof away from the housing.A check valve is fixedly connected onto the exhaust pipe. An alarm mechanism is disposed in the housing. An air inlet pipe is fixedly connected onto a sidewall of the housing. A valve is fixedly connected onto the air inlet pipe. The infusion bottle automatic stop alarm device of the invention does not need manual inspection, automatically alarms and stops infusion after the infusion of the infusion bottle is completed, and is simple and convenient; and offsets the influence of the water pressure change by changing the frictional force between a magnet ring and the outer side wall of the housing, gains an effect of adjusting the flow rate, and makes the infusion of the infusion bottle smooth.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to an automatic stop alarm device for infusion bottles based on the principle of air pressure. Background technique [0002] The infusion bottle is a bottle used for storing medicinal liquid for patient infusion. During the infusion process, external air needs to be continuously replenished to achieve air pressure balance inside and outside. In the existing infusion process, when sleeping or comatose patients undergo infusion, the patient's family members or nurses are required to take care of them. Due to the lowering of the liquid level in the infusion bottle, the probability of air in the bottle entering the infusion tube is greater, especially when the infusion is about to end. As the cross-sectional area of ​​the lower end of the infusion bottle decreases, the turbulence of the liquid in the bottle increases under the action of rising air bubbles, and the air often ...
