[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] For the above technical issues, refer to Figure 1 , Figure 2 The present embodiment provides a liquid droplet speed detection and alarm device, comprising a first shell 1 and a second shell 2, wherein the first shell 1 and the second shell 2 are connected and assembled into a shell by screws, and a groove structure 9 is formed on a side of the second shell 2 away from the first shell 1, and the liquid droplet speed detection and alarm device is clamped on the upper part of the infusion funnel through the groove structure 9.

[0028] The circuit board 8 is installed inside the first housing 1 and the second housing 2 by screws, the button 5 is electrically connected to the circuit board 8, the top of the button 5 extends to the outside of the first housing 1, and the dripping rate threshold of the liquid medicine is set by pressing the button 5, and the dripping rate threshold is stored in the circuit board 8. The display screen 4 is electrically connected to the circuit board 8.

[0029] The photoelectric sensor 6 is mounted on the second housing 2, and the photoelectric sensor 6 is aligned with the hollow position of the infusion funnel. When the medicine drips downward from the infusion funnel, the photoelectric sensor 6 sends a signal to the circuit board 8 to complete the collection of the dripping speed of the medicine, and the dripping speed of the medicine is displayed on the display screen 4.

[0030] The photoelectric sensor 6 can count the number of drops of medicine dripping downwards, and determine the dripping speed of the medicine liquid by continuously counting within a predetermined period of time, for example, the number of drops of medicine liquid dripping downwards within 1 minute is counted to determine the dripping speed of the medicine liquid. The circuit board 8 displays the collected dripping speed of the medicine liquid through the display screen 4, realizing real-time monitoring of the dripping speed of the medicine liquid.

[0031] At the same time, the circuit board 8 compares the collected dripping speed of the medicine liquid with the dripping speed threshold to determine whether the dripping speed of the medicine liquid reaches the dripping speed threshold to control whether to issue an alarm.

[0032] In the present application, the data collection, comparison and control processes are realized by programming the single chip microcomputer in the circuit board 8.

[0033] The dripping speed threshold includes a first dripping speed threshold and a second dripping speed threshold, wherein the first dripping speed threshold is used to define the lower limit of the dripping speed of the liquid medicine, and the second dripping speed threshold is used to define the upper limit of the dripping speed of the liquid medicine. By setting the first dripping speed threshold and the second dripping speed threshold, the range of the speed at which the liquid medicine drips downward is limited, and when the liquid medicine can drip downward within the limited speed range, it is ensured that the liquid medicine is delivered to the patient at a uniform speed.

[0034] The first circuit board 8 is electrically connected to a sound alarm 10 .

[0035] When the dripping speed of the medicine liquid is not within the range of the first dripping speed threshold and the second dripping speed threshold, for example, the speed at which the medicine liquid drips downward is very slow or the speed at which the medicine liquid drips downward is very fast, the speed at which the medicine liquid drips downward does not meet the requirements of the infusion.

[0036] The second circuit board 8 compares the collected dripping speed of the medicine liquid with the first dripping speed threshold and the second dripping speed threshold. According to the comparison result, the second circuit board 8 drives the sound alarm 10 to emit an alarm sound to prompt that the dripping speed of the medicine liquid does not meet the requirement.

[0037] Within a preset time length, for example, within 1 minute, if the number of drops of the liquid medicine dripping downwards collected by the photoelectric sensor 6 is 0, then the dripping rate of the liquid medicine is 0, indicating that the liquid medicine has been delivered. At this time, the second circuit board 8 drives the sound alarm 10 to emit an alarm sound to indicate that the liquid medicine has been delivered.

[0038] Reference Figure 3 , Figure 4 A panel film 3 is glued to the top surface of the first housing 1, and the panel film 3 is used to fix the display screen 4 from the peripheral side.

[0039] The lithium battery 7 is installed in the second housing 2, and the lithium battery 7 is electrically connected to the first circuit board 8, the display screen 4 and the sound alarm 10 respectively, and is used to supply power to the sound alarm 10, the first circuit board 8 and the display screen 4.

[0040] The volume of the alarm sound emitted by the sound alarm 10 is controlled by the second circuit board 8. For example, in a noisy environment, the second circuit board 8 controls the sound alarm 10 to emit a loud alarm sound, and at night, the second circuit board 8 controls the sound alarm 10 to emit a very low alarm sound, so as to meet the needs of various occasions.

[0041] Reference Figure 5 The groove structure 9 includes a first clamping hole 91, a second clamping hole 92, a third clamping hole 93 and a detection cavity 94 which are connected in sequence from top to bottom. The infusion funnel is clamped inside the third clamping hole 93, and the infusion tube above the infusion funnel is clamped in the first clamping hole 91 and the second clamping hole 92. The bottom of the infusion funnel extends downward into the detection cavity 94. The photoelectric sensor 6 is facing the hollow position of the infusion funnel to facilitate the collection of the dripping rate of the liquid medicine.

[0042] Among them, the radial dimension of the third clamping hole 93 is larger than that of the second clamping hole 92 and the detection cavity 94 at both ends. The third clamping hole 93 forms a space with contracted ends, which is convenient for accommodating infusion funnels of various shapes and is suitable for monitoring various infusion tubes.

[0043] When the drug solution drips downward from the infusion funnel, the photoelectric sensor 6 collects the number of drug solution drops per unit time, thereby monitoring the infusion speed.

[0044] Working principle:

[0045] The liquid drop rate detection and alarm device is clamped on the outside of the infusion funnel of the infusion tube through the groove structure 9, and the drip rate threshold of the liquid medicine is set by pressing the button 5, and the drip rate threshold is stored in the circuit board 8. A first drip rate threshold and a second drip rate threshold can be set to limit the range of the drip rate threshold. During the infusion process, the photoelectric sensor 6 collects the drip rate of the liquid medicine and displays it on the display screen 4.

[0046] When the dripping speed of the medicine collected by the photoelectric sensor 6 is not within the range defined by the first dripping speed threshold and the second dripping speed threshold, the circuit board 8 drives the sound alarm 10 to emit an alarm sound to prompt that the infusion speed of the medicine does not meet the requirements.

[0047] When the photoelectric sensor 6 detects that the number of drops of liquid medicine dripping per unit time is 0, the circuit board 8 drives the sound alarm 10 to emit an alarm sound to prompt that the liquid medicine has been completely infused.

[0048] Furthermore, corresponding to different occasions, the circuit board 8 can adjust the volume of the alarm sound emitted by the sound alarm 10, which is specifically achieved by programming the single-chip microcomputer in the circuit board 8.

[0049] The circuit board 8 communicates with an intelligent terminal, such as a mobile phone, and the first dripping speed threshold and the second dripping speed threshold can be set to the circuit board 8 by using the mobile phone.

[0050] When the dripping speed of the liquid medicine collected by the photoelectric sensor 6 is not within the range defined by the first dripping speed threshold and the second dripping speed threshold, the circuit board 8 can send a prompt command to the mobile phone terminal for prompting. This is specifically achieved through software programming.

[0051] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
