Description

A portable medical transfusion alarm

technical field

The invention relates to an alarm, in particular to a portable medical transfusion alarm.

Background technique

The medical disposable infusion sets currently used in clinical practice generally do not have the monitoring function of the infusion state. The nurse leaves the patient after giving the patient a hanging needle. Usually, the patient or the accompanying person needs to pay attention to the remaining amount of the medicine in the hanging bottle. When the medicine is about to be infused Call the nurse to change the dressing and remove the needle in time; if the patient falls asleep or the caregiver is negligent, it will cause air to enter or blood to return if the liquid is not dealt with in time.

There is an existing infusion device alarm, which is characterized by the fact that when the infusion device is infused normally, the external pressure of the cavity is greater than that when there is no liquid. The appropriate starting torque is set as the threshold. When the pressure in the cavity decreases, the alarm circuit is activated. Send out an alarm signal; however, this detection principle relying on cavity pressure requires a relatively delicate and complex structure, and the use of leverage will lead to a larger device volume; The setting of the alarm threshold pressure brings difficulties. If it is not set properly, false alarms or even no alarms will occur.

The other alarm is a liquid weight detection device composed of a mechanical electromagnetic induction system. When the liquid in the infusion bottle is reduced to a set weight (such as 50 ml), the weight sensor is connected, and the alarm control circuit is connected. The alarm sends out a warning sound, so that the patient and accompanying family members know that the liquid in the bottle is about to be infused; but this method of relying on weighing to determine whether the infusion is about to end is mainly designed for the glass bottle with a relatively large mass. Packed medicines, especially small doses of medicines, will call the police in advance, even because the weight of the medicines is less than the design weight, the police will not be called.

Contents of the invention

The purpose of the present invention is to provide a portable medical transfusion alarm in order to overcome the deficiencies of the prior art.

In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a portable medical infusion alarm, which includes a main body in the shape of a clip; the main body is provided with a drop detection device, a liquid level detection device, an infusion locking device, Battery door, power switch, alarm device and control device; the clamping device, liquid drop detection device and liquid level detection device are sequentially arranged at the clamping end of the body from top to bottom; the liquid drop detection device and liquid level detection The device feeds back the detection signal to the control device, and the control device sends control signals to the transfusion locking device and the alarm device.

Preferably, the internal shape of the clamping end of the body matches the shape of the drip chamber of the infusion tube.

Preferably, the liquid drop detection device is provided with an infrared emitting device and a receiving device, and the infrared emitting device and the receiving device of the liquid drop detection device are respectively arranged on the two chucks at the clamping end of the body.

Preferably, the liquid level detection device is provided with an infrared emitting device and a receiving device, and the infrared emitting device and the receiving device of the liquid level detection device are respectively arranged on the two chucks at the clamping end of the body.

Due to the application of the above-mentioned technical solution, the present invention has the following advantages compared with the prior art:

The portable medical transfusion alarm device of the present invention can realize accurate alarm through the liquid drop detection device and the liquid level detection device, and can be locked when the transfusion is about to end through the transfusion locking device, so as to stop the transfusion and prevent air from entering or returning blood; the integral device The structure is simple and small, the alarm control is accurate, the manufacturing cost is low, and it can be used repeatedly, which greatly relieves the anxiety of patients waiting for the end of the infusion, facilitates the recovery of patients, and reduces the work intensity of nursing staff.
