Abstract
The utility model relates to a pressure type transfusion speed sensor, which relates to a pressure type transfusion speed detection device and aims to detect transfusion speed when in intravenous transfusion so as to monitor and control transfusion speed via a computer. The pressure type transfusion speed sensor comprises a liquid medicine storage device 1, a differential pressure sensor 2 and a signal processing circuit 5. The liquid medicine storage device 1 is a storage device in a medical transfusion tube, the differential pressure sensor is a 26 PC series pressure sensor, a pressure extracting opening of the differential pressure sensor is connected with a small tube at the upper end of the liquid medicine storage device to sense pressure change in the storage device, the signal processing circuit 5 amplifies transfusion information obtained by the differential pressure sensor and converts the transfusion information into digital voltage or digital impulse signals received by the computer, and the computer processes the signals, thereby achieving the purpose of monitoring transfusion speed via the computer. The pressure type transfusion speed sensor has the advantages of simple structure, low cost, stability, reliability and capacity of realizing computer remote monitoring via the signal processing circuit.
Description
Technical field the utility model relates to a kind ofly to be imported medium in the human body or is passed to apparatus on the human body, particularly a kind of pressure type dropping speed sensor, and it is used to detect the detection of infusion or other tiny flow quantity.
The background technology intravenous drip infusion is the main method of modern medical service medication, it the direct afferent veins of big medicine amount liquid can be used in the added body moisture, nutrition, water down or get rid of toxin, keep electrolyte balance, supply with medicine etc.The speed of transfusion speed has bigger influence to patient's medical effect.Present infusion speed adopts the artificial counting method mostly, and can not real time monitoring, brings inconvenience for patient and medical personnel.
The summary of the invention the purpose of this utility model is to solve detection of infusion speed and computer remote monitoring problem.
For achieving the above object, the utility model adopts following technical scheme: pressure type dropping speed sensor, comprise soup reservoir, differential pressure pick-up and signal processing circuit, the pressure tappings of differential pressure pick-up is connected to soup reservoir upper end tubule, differential pressure pick-up wiring termination signal processing circuit.The soup reservoir adopts the reservoir in the existing medical woven hose; Differential pressure pick-up adopts existing 26PC series pressure transducer on the market; The drop information that signal processing circuit obtains differential pressure pick-up is through processing and amplifying, and converts the digital pulse signal that computer can receive to, and computer is handled this signal again, reaches the purpose of computer monitor transfusion speed.The wherein said differential pressure pick-up detection soup reservoir internal pressure of utilizing is changed to main innovate point of the present utility model.
The utility model beneficial effect is; Simple in structure, cost is low, can reliablely and stablely detect and dropping speed during infusion monitoring by computer, plays a part positive for improving medical effect and efficient.
