Problems solved by technology

Through observing and analyzing the current intravenous infusion process, it is concluded that there are two problems in the existing intravenous infusion equipment: first, someone must detect during the intravenous infusion process, and the infusion equipment cannot automatically judge whether the infusion is over and notify the medical staff in time treatment, leading to dangerous situations such as blood relapse in patients
Second, the flow rate regulator cannot automatically adjust the flow rate. When the liquid medicine is dripped, the flow rate cannot be lowered in time, resulting in blood return

Embodiment 1

[0034] Such as figure 1 , 2 As shown in and 3, an intravenous infusion detection device includes a disposable infusion set, a vibration detection assembly, a vibration power generation circuit 6, a battery BT1, a signal conversion circuit 4 and an alarm circuit 5. Disposable infusion sets include intravenous needles, injection needles, needle shields, infusion hoses, liquid medicine filters, flow rate regulators, drip pots, bottle stopper piercers, and air filters. The side of the dripping pot is provided with a piezoelectric sheet insertion groove 201 . The piezoelectric sheet insertion groove 201 communicates with the external environment, and does not communicate with the inner cavity of the dripping pot.

[0035] Such as image 3 As shown, the vibration detection component includes a piezoelectric sheet 101 , a first arc-shaped plate 102 and a second arc-shaped plate 103 . One end of the piezoelectric sheet 101 is fixed to the inner surface of the first arc-shaped plat...

Embodiment 2

[0046] Such as figure 2 , 3 As shown in and 7 , an intravenous infusion detection device includes a disposable infusion set, a flow rate adjustment mechanism, a vibration detection component, a vibration power generation circuit 6 , a signal conversion circuit 4 and a controller 7 . The disposable infusion set includes an intravenous needle, an injection needle, a needle shield, an infusion hose 305, a liquid medicine filter, a drip pot, a bottle stopper piercer and an air filter. The outer surface of the dripping pot is provided with a piezoelectric sheet insertion groove 201 . The piezoelectric sheet insertion groove 201 communicates with the external environment, and does not communicate with the inner cavity of the dripping pot.

[0047] Such as image 3 As shown, the vibration detection component includes a piezoelectric sheet 101 , a first arc-shaped plate 102 and a second arc-shaped plate 103 . One end of the piezoelectric sheet 101 is fixed to the inner surface of...

Abstract

The invention discloses an intravenous transfusion detection device and a detection method thereof. Someone must detect during the intravenous infusion, and the infusion instrument cannot automatically judge whether the infusion is over. The invention relates to an intravenous infusion detection device, which comprises a disposable infusion set, a vibration detection assembly, a battery and a signal conversion circuit. The side of the dripping pot is provided with a piezoelectric sheet insertion groove. The vibration detection component includes a piezoelectric sheet, a first arc plate and a second arc plate. One end of the piezoelectric sheet is fixed to the inner surface of the first arc-shaped plate. The first arc-shaped plate is hinged to one side edge of the second arc-shaped plate. The signal conversion circuit includes an operational amplifier chip and an exclusive OR gate. The operational amplifier chip includes a first operational amplifier and a second operational amplifier. The present invention detects the vibration signal generated when the drop drops in the drip pot through the piezoelectric film, and judges whether the infusion is completed, thereby realizing automatic real-time monitoring in the intravenous infusion, and giving the patient the most comfortable and safe infusion experience.

Description

technical field [0001] The invention belongs to the technical field of medical auxiliary equipment, and in particular relates to an intravenous infusion detection device and a detection method thereof. Background technique [0002] Intravenous infusion therapy is a particularly important treatment method in medical care. Due to its fast drug effect, low irritation and rapid administration, it is widely used in major medical institutions today. Through observing and analyzing the current intravenous infusion process, it is concluded that there are two problems in the existing intravenous infusion equipment: first, someone must detect during the intravenous infusion process, and the infusion equipment cannot automatically judge whether the infusion is over and notify the medical staff in time The treatment will lead to dangerous situations such as bleeding back to the patient. Second, the flow rate regulator cannot automatically adjust the flow rate. When the liquid medicine ...
