Description

Technical Field

[0001] The utility model relates to a visual dripping speed regulator for medical infusion, belonging to the technical field of medical supplies. Background Art

[0002] In medical treatment, infusion is a common and effective treatment method, especially when the patient is sick. However, since each person's vascular system is unique and their tolerance varies, the regulation of the infusion rate is particularly important. The infusion set has become a key tool for regulating this process, and its design flexibility allows medical staff to make personalized adjustments based on the patient's specific situation. When using the infusion set, doctors will fully consider many factors such as the patient's physical condition, vascular strength, and disease type. By accurately adjusting the drip rate of the infusion set, patients can avoid discomfort during the infusion process, such as dizziness, nausea and other symptoms. This personalized treatment method effectively reduces the patient's discomfort and improves the effectiveness of the treatment. In addition, medical staff will closely observe the patient's physiological reactions and adjust the infusion rate in time to ensure the smooth progress of the treatment process. Through this meticulous regulation, not only can the safety of treatment be improved, but it also helps to shorten the patient's recovery time. To this end, the industry has successively developed a variety of infusion speed regulating devices. For example, the Chinese utility model patent with the authorization announcement number CN214970353U discloses a medical infusion regulator, and specifically discloses a regulator body and an adjusting wheel, wherein at least one guide groove is arranged inside the regulator body, and the central axis of the adjusting wheel can roll along the guide groove; the regulator body is penetrated by an infusion tube, and the extension direction of the infusion tube is consistent with the extension direction of the guide groove; the outside of the regulator body is provided with a scale mark corresponding to the adjusting wheel, and the scale mark indicates the dripping speed. However, this scheme controls the dripping speed of the infusion by the degree of pressure of the adjusting wheel on the infusion tube. When the patient has a strong tolerance and wants to shorten the infusion time, the dripping speed cannot be further accelerated. Utility Model Content

[0005] In the above-mentioned medical infusion visual drip rate regulator, the light sensor is located at the front end of the tube groove; when the first Y-shaped frame and the second Y-shaped frame rotate, the roller and the infusion hose are squeezed.

[0006] The aforementioned visual drip rate regulator for medical infusion has an operation button located on the side of the display screen at the front end of the shell cover; and a convex ring is provided at the rear end of the shell cover, which cooperates with the inner wall of the shell.

[0007] The aforementioned visual drip rate regulator for medical infusion has a plurality of first threaded holes on the front of the shell; and a first countersunk hole corresponding to the first threaded holes is provided on the shell cover.

[0008] The aforementioned medical infusion visual drip rate regulator has a plurality of second threaded holes at the rear of the shell; a protective cover is connected to the rear of the shell, and the protective cover is provided with second countersunk holes corresponding to the second threaded holes.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The utility model is connected to the infusion hose through the pipe groove, and then the motor is started. The motor drives the first Y-shaped frame and the second Y-shaped frame to rotate simultaneously. During the rotation process, the roller between the first Y-shaped frame and the second Y-shaped frame squeezes the infusion hose, so that the liquid droplets in the infusion hose flow downward along with the roller during the squeezing process, thereby adjusting the dripping speed of the liquid droplets. When a faster dripping speed is required, the motor speed is increased; when a slower dripping speed is required, the motor speed is reduced or the roller squeezes the infusion hose and stops. The light sensor detects the volume of the liquid droplets flowing through the infusion hose and sends it to the circuit board. The circuit board calculates the liquid droplet speed after analysis and then displays it on the display screen.

[0013] 2. The limiting mechanism of the utility model is used to prevent the infusion hose from falling off during use. When connecting the infusion hose, the infusion hose is placed along the notch of the tube groove, and then the infusion hose moves along the first arc slope to the arc-shaped portion. When passing through the arc-shaped portion, the infusion hose will be squeezed, and only then can it pass through the arc-shaped portion and be clamped between the tube groove and the second arc slope, thereby limiting the forward and backward movement of the infusion hose. After the utility model is installed on the infusion hose, it will slide down due to gravity until it stops moving after it hits the upper end of the drip pot. BRIEF DESCRIPTION OF THE DRAWINGS
