Problems solved by technology

For the detection of the infusion tube of the disposable infusion set, the drop counting method or optical measurement method is generally used. This method is generally used to detect and alarm after the liquid in the infusion container has been dripped. At this time, the nurse has no time to deal with it. , leading to untimely treatment also has adverse effects on patients
[0004] The detection device is installed on the infusion packaging container, because medical infusion packaging containers include glass bottles, plastic bottles, and soft bags, and soft bags can be divided into PVC soft bags and non-PVC soft bags (PP / PE) according to the materials used. , different types, glass bottles and plastic bottles may not be able to be tested

Embodiment 1

[0030] Such as figure 1 As shown, a disposable infusion device with liquid detection and early warning is provided. A liquid detection and early warning device is provided between the liquid inlet needle 2 and the drip pot 3 of the main body 1 of the infusion device.

[0031] The liquid detection and early warning device includes a delay infusion tube 4, a liquid detection tube 5, and a photoelectric detection head 8;

[0032] The time-delay infusion tube 4 contains a liquid detection tube 5, a floating body 6, and the floating body 6 is located in the liquid detection tube 5. The upper end of the time-delay infusion tube 4 and the upper end of the liquid detection tube 5 communicate with the liquid inlet needle 2. When the lower end of the infusion tube 4 communicates with the drip pot 3 through the infusion tube;

[0033] The photoelectric detection head 8 is arranged on the upper part of the delay infusion tube 4 or the liquid detection tube 5 .

[0034] The delay infusio...

Embodiment 2

[0037] Example 2 figure 2 The photoelectric detection head 8 described in the above is clamped or snapped into the upper part of the liquid detection tube 5 .

[0038] The photoelectric detection head 8 is connected to the alarm circuit in a wired or wireless manner. When the floating body 6 in the liquid detection tube 5 descends with the liquid and the floating body 6 cannot block the light emitted by the photoelectric detection head 8, the photoelectric detection head 8 will output an electrical signal. Trigger the alarm circuit for pre-alarm.

[0039] The time-delay infusion tube 4 and the liquid detection tube 5 are made of transparent materials.

[0040] The floating body 6 is made of non-transparent material, and the specific gravity of the floating body 6 is slightly lower than that of the liquid.

[0041] The floating body 6 adopts a floating column or a floating ball.

[0042] Considering the floating column, its side wall has a large area and strong light shield...

Abstract

The invention discloses a disposable infusion apparatus with liquid detection and early warning. A liquid detection and early warning device is arranged between a liquid inlet needle and a drip cup ofan infusion apparatus main body, wherein the liquid detection and early warning device comprises a delay infusion tube, a liquid detection tube and a photoelectric detection head; the liquid detection tube is contained in the delay infusion tube; or the liquid detection tube and the delay infusion tube are separately arranged; a floating body is positioned in the liquid detection tube; the photoelectric detection head is connected to an alarm circuit in a wired or wireless mode; when the floating body in the liquid detection tube descends along with liquid and the floating body cannot shieldlight emitted by the photoelectric detection head, the photoelectric detection head outputs an electric signal to trigger the alarm circuit to perform early warning. The disposable infusion apparatuswith liquid detection and early warning disclosed by the invention comprises the delay infusion tube; and infusion time can be prolonged by the liquid stored in the infusion tube after an alarm, so that a nurse has time to go to a hospital bed to handle.

Description

technical field [0001] The invention relates to the field of medical equipment industry, in particular to a disposable infusion set with liquid detection and early warning. Background technique [0002] Disposable infusion sets are mainly used for infusion therapy in medical work. Intravenous infusion therapy is a commonly used treatment method in clinical medical work, and many patients need to infuse several groups of liquid medicine a day. Due to the long infusion time, the patient is bedridden and fatigued, and tends to fall asleep during the infusion. If the liquid is transfused and the medical staff cannot change the dressing or pull out the needle in time, air will enter the blood vessel and form an air embolism. If it is mild, it will delay the treatment and cause pain to the patient; if it is serious, it will seriously endanger the patient and cause an accident. [0003] At present, there are many devices for monitoring and alarming the infusion, and these device...
