Description
Technical field
This utility model relates to medical apparatus and instruments, is specifically related to a kind of infusion set.
Background technology
Infusion set generally comprises infusion vessel, upper tubing, drips kettle and following tube for transfusion, and the upper tubing upper end is communicated with infusion vessel, the lower end is communicated with a kettle, drips the kettle bottom and is communicated with following tube for transfusion upper end.Infusion vessel can be infusion bottle or transfusion bag, is used for the splendid attire medicinal liquid.Drip kettle and be used for showing droplet speed and an aerofluxus, also can be used to promptly add medicine.Medicinal liquid in the infusion vessel splashes in the kettle through upper tubing; In the normal infusion process, the medicinal liquid that drips in the kettle keeps certain liquid level, and its hydraulic pressure is greater than venous pressure, thereby makes the medicinal liquid that drips in the kettle enter down tube for transfusion from its bottom, and by in the lasting inflow of the transfusion needle venous patient that is connected down the tube for transfusion lower end.In addition, flow regulator is installed also usually on the infra tube for transfusion, is used for regulating transfusion speed.
At present, in infusion process, rely on the medicinal liquid in medical personnel, entourage or the own perusal infusion vessel of patient whether to use up, tend to occur not having in time finding the situation that medicinal liquid uses up, can not in time change infusion vessel, cause taking place situations such as patient blood refluence, serious also may cause malpractice.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of infusion set, when this infusion set can the medicinal liquid in infusion vessel uses up, sends alarm signal.The technical scheme that adopts is as follows:
A kind of infusion set, comprise infusion vessel, upper tubing, drip kettle and following tube for transfusion, the upper tubing upper end is communicated with infusion vessel, the lower end is communicated with a kettle, dripping the kettle bottom is communicated with following tube for transfusion upper end, it is characterized in that: described infusion set also comprises pressure transducer, control circuit and alarm, pressure transducer is close to the outer surface that drips the kettle lower sidewall, and pressure transducer is connected with the corresponding input of control circuit, and alarm is connected with the corresponding outfan of control circuit.
Above-mentioned pressure transducer is used for induction and drips the pressure that the kettle lower sidewall is transmitted, and is transferred to control circuit after converting the signal of telecommunication to.In the normal infusion process, the medicinal liquid that drips in the kettle keeps certain liquid level, and the pressure size that this moment, pressure transducer was sensed remains unchanged; When the medicinal liquid in the infusion vessel used up, the liquid level of dripping the medicinal liquid in the kettle descended and last emptying gradually; In the process that the liquid level of the medicinal liquid in dripping kettle descends gradually, medicinal liquid reduces gradually to the hydraulic pressure that a kettle lower sidewall produces, and the force value that pressure transducer is sensed also reduces gradually; When the amplitude that reduces of the force value of sensing when pressure transducer reached preset value, control circuit output control signals to alarm, and alarm sends alarm signal.
Above-mentioned pressure transducer is close to a kettle lower sidewall, because the common employing of a kettle has certain elastic material (as TPO (TPE)) and makes, deformation can take place under pressure, therefore dripping the kettle sidewall can outwards transmit dripping the kettle internal pressure, and pressure transducer can be sensed the variation of dripping the kettle internal hydraulic pressure.Further, above-mentioned infusion set also comprises the pressure transducer installing rack, the pressure transducer installing rack comprises left curved splint and right arc clip plate, described pressure transducer is located at the inboard of left curved splint or the inboard of right arc clip plate, curved splint two ends, a left side respectively are provided with a left brace, right arc clip plate two ends respectively are provided with a right brace, two left braces are corresponding one by one with two right braces, left side brace is connected by bolt with right brace, and left curved splint and right arc clip plate are clamped jointly and dripped the kettle lower sidewall.The pressure transducer installing rack is played a supporting role to pressure transducer, makes pressure transducer remain on the desired position, thereby guarantees that pressure transducer responds to the variation of dripping the kettle internal hydraulic pressure more accurately.By above-mentioned pressure transducer installing rack is set, making pressure transducer is dismantled and assembled the connection with dripping between the kettle, and like this, pressure transducer, control circuit and alarm can be realized reusing, and reduce use cost.
Above-mentioned alarm can be sound-producing device (as buzzer), sounds as alarm signal.Above-mentioned alarm also can be light-emitting device (as light emitting diode, light emitting diode preferably glimmers), and is luminous as alarm signal.Above-mentioned alarm also can comprise sound-producing device (as buzzer) and light-emitting device (as light emitting diode, light emitting diode preferably glimmers), can sound simultaneously with luminous as alarm signal.
This utility model is by arranging pressure transducer, control circuit and alarm, and make pressure transducer be close to the outer surface that drips the kettle lower sidewall, when the medicinal liquid in the infusion vessel uses up, the liquid level of dripping the medicinal liquid in the kettle descends gradually and reduces gradually dripping the hydraulic pressure that the kettle lower sidewall produces, pressure transducer can detect this hydraulic pressure variation and signal is transferred to control circuit, control circuit outputs control signals to alarm, make alarm send alarm signal, remind medical personnel in time to change infusion vessel, avoid taking place situations such as patient blood refluence.
