Abstract

The utility model provides a digital display for drips, which is composed of a housing, a power switch, a circuit board, a battery, an infrared light emitting tube, and a photoelectric receiving tube. The middle of the front surface of the housing is provided with a dripping pipette clamping groove of which the upper part is provided with a baffle board, the upper part of the surface of the housing on one side of the dripping pipette clamping groove is provided with the power switch, and the circuit board is arranged in the housing. The battery is arranged behind the circuit board in the housing, the infrared light emitting tube is fixed on one side of the dripping pipette clamping groove in the housing, and the photoelectric receiving tube is fixed on the other side of the dripping pipette clamping groove in the housing to be opposite to the infrared light emitting tube. The digital display for drips of the utility model has the characteristics of reasonable design, simple structure, and convenient use and can accurately and clearly display the drip number of physic liquor drips per minute, so that the drip number of physic liquor drips can be controlled at an optimal drip number, which is helpful to the drug absorption of patients.

Description

The drop device for digit-displaying

1, technical field

This utility model relates to a kind of medical supplementary instrument, specifically a kind of drop device for digit-displaying.

2, technical background

When medical personnel beat the transfusion bottle liquid medicine injection to patient, usually just lean on experience or see the number that drips of showing to determine the medicinal liquid per minute, thereby the medicinal liquid drop is dripped number to be determined in optimum range, but the error of doing like this is quite big, when beating transfusion bottle for cardiovascular patient or infant patient, if can not dripping the per minute drop number, medical personnel determine that within the specific limits the patient can feel very ill, the serious complication that also can cause the patient.

3, summary of the invention

The purpose of this utility model provides a kind of drop that can accurately clearly demonstrate the medicinal liquid per minute and drips number, drips number thereby the medicinal liquid drop is dripped numerical control built in the best, helps the drop device for digit-displaying of patient to the absorption of medicine.

The purpose of this utility model realizes in the following manner, has the minim pipette clamp grooves in the centre of the front surface of housing, so just can be with drop device for digit-displaying clamping on minim pipette; During use, battery is contained in the circuit board back, with drop device for digit-displaying clamping on minim pipette, the variation of infraluminescence pipe by being fixed on minim pipette clamp grooves both sides and photoelectric receiving tube induction medicinal liquid drop, again by being arranged on the intravital single-chip microcomputer deal with data of shell shows current per minute drop by charactron the number that drips, if the speed of dripping of drop exceeds the scope that single-chip microcomputer is stipulated,, remind medical personnel and patient to note just the buzzer that is arranged on the circuit board can send sound.
