AI Technical Summary
The existing infusion device only calls the alarm after the liquid is injected, resulting in the problem of low liquid surface. It is necessary to design a device that can alarm after the liquid is injected and is suitable for existing infusion devices.
A liquid level warning infusion device for infusion bags is designed, and the external structure is inserted directly on the infusion bottle/bag. The liquid level position is detected through the liquid level detector. When the liquid level drops to a certain position, the alarm is issued. The alarm includes a buzzer and a warning light.
It realizes alarm after the liquid is injected, avoids the problem of low liquid surface, and has a good reminder effect. It does not need to improve or change the structure of existing infusion devices.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to an infusion bag liquid level warning infusion set. Background Art
[0002] An infusion alarm is designed mainly for the blind, intensive care patients, the elderly living alone, the disabled, patients with long-term infusion or bedridden patients according to the law of repeated infusion dressing change. It is an electronic device for monitoring infusion and indicating the emptying of the drip chamber. It consists of a single-chip microcomputer, an induction clip, a manual switch and a buzzer. Some devices can display the drip speed and heating function; most of the current precision infusion sets have a Murphy's dropper directly below the needle, and the alarm is installed on the infusion tube. The alarm only sounds when the liquid in the Murphy's tube is finished. At this time, the liquid level in the tube is very low, which is prone to problems. It is necessary to design a device that can alarm when the liquid in the infusion tube / infusion bag is finished, and it should be applicable to the existing infusion devices at the same time.
[0003] Therefore, we propose an infusion bag liquid level warning infusion set to solve the above problems. Content of the Utility Model
[0004] The purpose of the utility model is to provide an infusion bag liquid level warning infusion set to overcome the disadvantages existing in the prior art.
[0005] To achieve the above purpose, the utility model adopts the following technical solutions:
[0006] An infusion bag liquid level warning infusion set includes a cylindrical shell, the cylindrical shell is hollow, and an open mouth is provided at the bottom of the cylindrical shell. A cover is threadedly sleeved on the open mouth, and a rubber mouth structure similar to that of an infusion bottle is provided on the cover. An infusion needle is fixedly connected and communicated with the upper end of the cylindrical shell. A power supply is fixedly arranged on one side of the cylindrical shell, and a housing is fixedly arranged on the other side of the cylindrical shell. A liquid level detector, a controller and an alarm are arranged in the housing.
[0007] Preferably, the cylindrical shell is made of transparent glass material.
[0008] Preferably, the power supply adopts a replaceable lithium battery power supply.
[0009] Preferably, an annular hoop is sleeved outside the infusion needle, the annular hoop is fixedly connected with the cylindrical shell, and the annular hoop is made of rubber material.
[0010] Preferably, the alarm includes a buzzer and an alarm warning light.
[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: The device adopts an external structure, directly inserts on the infusion bottle / bag to let the liquid flow down, and then inserts the infusion tube on the device. It can be directly used without improving or changing the structure of the existing infusion instruments. At the same time, a liquid level detector is used to detect the liquid level in the device. When the liquid level in the device drops to a certain position, an alarm is issued, which has a good reminder effect. At the same time, the liquid level in the infusion tube will not be too low when the alarm is triggered. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] 1 cylindrical shell, 2 cover, 3 infusion needle, 4 power supply, 5 shell, 6 liquid level detector, 7 controller, 8 alarm, 9 annular hoop. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0018] Refer to Figures 1-3 A liquid level warning infusion device for an infusion bag shown, including:
[0019] As the main body, a cylindrical shell 1 is made of transparent glass material, which is convenient for observing the internal situation. At the same time, the cylindrical shell 1 is hollow and there is an open mouth at the bottom of the cylindrical shell 1. A cover 2 is threadedly sleeved on the open mouth. The cover 2 is provided with a rubber mouth structure similar to that of an infusion bottle, which can be inserted and connected by an infusion tube to export the infusion liquid. Moreover, an infusion needle 3 is fixedly connected and communicated at the upper end of the cylindrical shell 1, which can be inserted into an infusion bag or an infusion bottle to introduce the infusion liquid into the cylindrical shell 1;
[0020] In order to achieve the effect of liquid level detection, a power supply 4 is fixedly arranged on one side of the cylindrical shell 1. The power supply 4 adopts a replaceable lithium battery power supply to ensure continuous use. A shell 5 is fixedly arranged on the other side of the cylindrical shell 1. A liquid level detector 6, a controller 7 and an alarm 8 are arranged in the shell 5. The alarm 8 includes a buzzer and an alarm warning light. The above components all adopt the prior art and will not be elaborated here.
[0021] Liquid may enter the interior of the device, making it relatively heavy. Therefore, an annular hoop 9 is sleeved outside the infusion needle 3. The annular hoop 9 is fixedly connected to the cylindrical housing 1. The annular hoop 9 is made of rubber material and can be deformed to fit around the mouth of the infusion bottle / bag to assist in fixation.
[0022] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
