Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. When an element is referred to as being "disposed on" another element, it can be directly on the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1, an embodiment of the present invention provides a drip safety device 100, which includes a frame 10, a liquid level detecting module 20, and a flow control module 30.

Specifically, the frame 10 is used for accommodating a dropper bottle 200, and it is understood that the dropper bottle 200 is used for containing liquid substances such as medicine, nutrient solution, and the like. The liquid level detecting module 20 is mounted on the frame 10 and can detect the liquid level in the dropper 200. The flow control module 30 is connected to the liquid level detection module 20, and when in actual use, the flow control module 30 is sleeved on the dropper 300 connected to the dropper bottle 200.

It can be understood that the liquid in the dropper bottle 200 flows through the dropper 300 before being injected into the human body through the injection needle, and the dropper 300 is a flexible tube, and the flow rate of the liquid can be adjusted by changing the sectional size thereof. Therefore, when the drip tube 300 is clamped so that the cross-sectional size of the clamped portion is zero, the flow of the liquid in the drip tube 300 is stopped.

The drip safety device 100 operates on the principle of: the liquid level detection module 20 detects the liquid level in the dropper bottle 200 in real time. The liquid level detecting module 20 can preset a minimum liquid level, and when the liquid level detecting module 20 detects that the liquid level in the dropper bottle 200 reaches the preset minimum liquid level, the flow control module 30 connected to the liquid level detecting module 20 starts and clamps the dropper 300 to stop the flow of liquid in the dropper 300.

In this embodiment, the liquid level detecting module 20 may adopt a light sensing device in the prior art, and obtain the liquid level height in the dropper bottle 200 through an infrared light source and a light source detecting circuit. In other embodiments, the liquid level detection module 20 can also be other devices capable of detecting the liquid level in the transparent container.

In this embodiment, the flow control module 30 includes a fixing member 31 and a fitting member 32 capable of fitting with the fixing member 31 to clamp the drip tube 300, wherein the fixing member 31 is sleeved outside the drip tube 300, and the fitting member 32 is disposed at one end of the fixing member 31 and capable of moving relative to the fixing member 31.

Specifically, the fixing member 31 includes a first end 311 and a second end 312 opposite in the first direction, and a third end 313 and a fourth end 314 opposite in the second direction. The drip tube 300 extends through the first end 311 and the second end 312 of the fixing member 31, and the fitting member 32 is located at the third end 313 and can move in the second direction. In this embodiment, the first direction and the second direction are perpendicular to each other.

In practical use, when the liquid level detecting module 20 detects that the liquid level in the dropper bottle 200 reaches the preset minimum liquid level, the flow control module 30 is activated to clamp the dropper 300 so as to stop the flow of liquid in the dropper 300. At this time, the fitting member 32 moves toward the fourth end 314 to press the dropper 300, and the dropper 300 is continuously pressed until the liquid stops flowing by being clamped, so that the fitting member 32 stops moving.

The flow control module 30 may be an electromagnetic switch, i.e. the fourth end 314 of the fixed member 31 is provided with a magnetic member (not shown), and the mating member 32 is an electromagnet capable of generating a magnetic attraction on the magnetic member when the electric current is applied. Therefore, when the flow control module 30 needs to be activated to clamp the dropper 300, the mating member 32 belonging to the electromagnet is energized to generate an attractive force with the magnetic member, so that the dropper 300 can be clamped.

The flow control module 30 further comprises a release button 33, and when the clamping action of the flow control module 30 on the drip tube 300 needs to be released, the power supply to the electromagnet can be cut off through the release button 33, so that the attractive force between the electromagnet and the magnetic piece is eliminated.

It should be noted that the flow control module 30 can not only directly clamp the dropper 300 to stop the flow of the liquid in the dropper 300 when the liquid level in the dropper bottle 200 reaches the minimum liquid level, but also perform a certain liquid flow rate adjustment before the liquid level in the dropper bottle 200 reaches the minimum liquid level. For example, the fitting 32 may be moved toward the fixing member 31 by a predetermined distance to cause a corresponding degree of squeezing of the drip tube 300, thereby adjusting the liquid flow rate in the drip tube 300.

It can be understood that adjusting the fluid flow rate can meet the personal requirements of the patient in the process of infusion to a certain extent, because some patients want to shorten the time to increase the fluid flow rate, and some patients have pain feeling when the fluid flow rate is higher and need to reduce the fluid flow rate. In the prior art, each dropper 300 is provided with a component having a liquid flow regulating function, and the component is a disposable product together with the dropper 300. However, the flow control module 30 also has the function of adjusting the liquid flow rate, and a liquid flow adjusting component provided to each dropper 300 can be omitted, so that the material is saved, and the cost is reduced.

Further, the drip safety device 100 may further include a warning module (not shown) connected to the liquid level detecting module 20, and the warning module sends a prompt message to the medical staff when the liquid level detecting module 20 detects that the liquid level in the drip bottle 200 reaches the minimum liquid level, and the medical staff goes to replace the new drip bottle 200 or remove the injection needle inserted into the human body after receiving the prompt message, as in the prior art. In this embodiment, the drip safety device 100 includes both the flow control module 30 and the warning module, so that the medical staff does not need to hurry to handle the drip safety device after receiving the prompt message, and the patient can feel safer while waiting.

In addition, other changes may be made by those skilled in the art without departing from the spirit of the invention, and it is intended that all such changes be considered within the scope of the invention.
