Description

An intelligent transfusion alarm device

technical field

The utility model relates to a medical alarm device, in particular to an intelligent infusion alarm device.

Background technique

Infusion is the basic way for various medical institutions to effectively treat patients. Through infusion, drugs can be effectively injected into the patient's body to achieve the purpose of treatment. The insertion and removal of needles for infusion are all done by nurses. However, due to the limited number of nurses in each department, one nurse needs to take care of multiple patients. Backflow of blood; sometimes the infusion time is long, and the patient may fall asleep or ignore the time of infusion, especially for patients without family care, which is more likely to occur, which brings life danger to the patient.

There is following shortcoming in prior art:

Existing transfusion alarms on the market are roughly divided into two categories: one is to realize transfusion alarms by infrared sensors. This is a product that existed more than ten years ago. It has also undergone market tests and cannot be popularized. This product has the following limitations: the infrared principle consumes a lot of power, and it must be plugged in directly, but the sockets in the hospital are special and limited; it must be attached to the infusion pole, and now not all hospitals use the infusion pole for infusion; according to a certain Judging by the number of infusion drops in time, the error is relatively large, because there is a gap in the density of different medicines. The second is to realize the infusion alarm through gravity induction, and use the gravity principle to control the infusion throughout the whole process. The principle is simple, but it is extremely difficult to be precise.

The Chinese patent application number 201010232012.9 discloses an infusion alarm, which is provided with an infrared probe capable of detecting the infusion bottle, and is provided with an alarm horn. When in use, the mouth of the infusion bottle can be directly fixed, and when the infusion in the bottle is nearly exhausted, the forecast probe will send out an early warning prompt through the alarm horn. However, this alarm only realizes the alarm function, and when the medical staff cannot arrive in time, effective measures cannot be taken to prevent dangers such as blood backflow from occurring.

Utility model content

The purpose of this utility model is to provide an intelligent infusion alarm device that can automatically block the liquid flow of the infusion tube in order to overcome the above-mentioned defects in the prior art.

The purpose of this utility model can be achieved through the following technical solutions:

An intelligent infusion alarm device, which is used to alarm the liquid in the infusion bottle when it is about to be drained, and is characterized in that the device includes a micro control unit MCU and a reset switch and a photoelectric sensor respectively connected to the micro control unit MCU . An alarm prompting mechanism and a motor locking mechanism, the photoelectric sensor is arranged on the mouth of the infusion bottle, the sensing height is 0.5-2 cm above the lowest point of the mouth of the infusion bottle, and the motor locking mechanism is arranged on the infusion tube.

The motor locking mechanism includes a block, an electric lock block and a motor, and the motor is connected to the micro control unit MCU and the electric lock block respectively, and the block is provided with a bar-shaped slot for accommodating the infusion tube. The electric lock block described above is set opposite to the bar-shaped draw-in slot.

The electric lock block is semi-cylindrical, and its curved surface is set opposite to the bar-shaped slot.

The alarm prompting mechanism includes an alarm indicator light and a buzzer respectively connected with the micro control unit MCU.

The device also includes a power indicator light connected with the micro control unit MCU.

Compared with the prior art, the utility model has the following advantages:

(1) Combining photoelectric sensor, alarm prompting mechanism and motor locking mechanism to realize automatic detection, alarm and locking of the liquid level, prompting the medical staff or accompanying personnel, and automatically blocking the infusion, not only notifying the medical staff that there is a patient who needs to pull out the needle , It also provides a certain amount of time for the medical staff to avoid blood backflow caused by the dripping of the medicine, which improves the overall work efficiency of the hospital.

(2) The induction height is 0.5-2cm above the lowest point of the infusion bottle mouth, and a certain amount of reserved liquid is reserved. Combined with the use of the reset switch, the infusion can be resumed by triggering the reset switch within a period of time after the medical staff responds. The circulation of the tube will be used up, and the reserved liquid volume will be used up to reduce the waste of liquid medicine.

(3) When the electric lock block moves to the bar-shaped slot, the electric lock block squeezes the infusion tube in the bar-shaped slot to stop the liquid in it from flowing, and the reverse movement can restore the flow of the infusion tube, and the recovery speed is fast.

(4) The electric lock block is semi-cylindrical, and its curved surface is arranged opposite to the strip-shaped draw-in slot, so that the damage to the infusion tube is small.

(5) The alarm indicator light and the buzzer realize the sound and light alarm and play the role of effective reminder.

(6) There is a power indicator light, which is beneficial to check whether the device is working normally.
