Description
Technical field
The invention belongs to the field of medical instrument technology, are related to a kind of inexpensive portable infusion monitoring alarm.
Background technique
Because of the negligence of patient or caregiver when infusion, failing to close fluid-delivery valve in time after having caused infusion bottle empty causes
Medical security risks can endanger patients ' lives safety when serious, existing similar device function is more, using complexity, cost it is excessively high,
It safeguards cumbersome, unreliable, not readily portable, not applicable, greatly hinders its promotion and application.
Summary of the invention
In order to overcome the disadvantages mentioned above of the prior art, the present invention provides a kind of inexpensive portable infusion monitoring, alarming dress
It sets, it can judge drop speed by singlechip controller, drip speed when detecting in the state of perfusion tube dropping funnel position detection drop
It can determine whether that infusion bottle stops when being zero, and issue sound-light alarm standby signal immediately, patient or caregiver is reminded to call doctor
Shield personnel change bottle, because of disease when having the characteristics that use is simple, low in cost, easy to maintain, easy to carry, while avoiding infusion
The negligence of people or caregiver, failing to close fluid-delivery valve in time after having caused infusion bottle empty leads to medical security risks.
The technical solution adopted by the present invention to solve the technical problems is：A kind of low cost portable infusion monitoring, alarming dress
It sets, including body, the top of body is equipped with elastic clip for clamping perfusion tube dropping funnel top, then sets respectively in the two sides of body
It is equipped with infrared transmitting tube and infrared receiving tube, infrared transmitting tube and infrared receiving tube pass through in signal connecting wire and circuit board
Singlechip controller is connected, and singlechip controller is connected with the intracorporal light emitting diode of the machine that is similarly disposed at and buzzer, circuit
Plate drives infrared transmitting tube detection, then received signal is sent back circuit board by infrared receiving tube and is judged by circuit board, empty bottle
Shi Ze realizes sound-light alarm by light emitting diode and buzzer.
The singlechip controller has been internally integrated CPU, voltage comparator, ADC, interruption system and timer.
The circuit board and the lithium coin cells being arranged in body rear end detachable battery seat are connected by lithium coin cells
Electric power is provided.
The infrared transmitting tube can be blocked when there is drop to fall, to export faint electric signal, be input to monolithic
Voltage comparator conditioning inside machine controller is at the fast pulse signal of drop.
The singlechip controller just controls lumination of light emitting diode flashing, control buzzer hair after detecting infusion
Prompt tone reminds user to pay attention to by strong sound and light program.
The light emitting diode can be used as fast indicator is dripped, and flashing speed becomes with the velocity variations that drop is fallen
Change, then flashing is fast fastly for transfusion speed, and then flashing is slow slowly for transfusion speed, and infusion does not flash then when stopping.
The beneficial effects of the invention are as follows：It can pass through single-chip microcontroller control in the state of perfusion tube dropping funnel position detection drop
Device judgement drop speed processed, can determine whether that infusion bottle stops when detecting that drop speed is zero, and issue sound-light alarm standby signal immediately,
It reminds patient or caregiver to call medical staff and changes bottle, have using simple, low in cost, easy to maintain, easy to carry etc.
Feature, while failing to close in time after having caused infusion bottle empty defeated because of the negligence of patient or caregiver when avoiding infusion
Liquid valve leads to medical security risks.

Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples.
Referring to Fig. 1 and Fig. 2, a kind of inexpensive portable infusion monitoring alarm, including body, the top of body are equipped with
Elastic clip 1 is then respectively arranged with infrared transmitting tube 2 in the two sides of body and infrared connects for clamping 16 top of perfusion tube dropping funnel
Closed tube 3, infrared transmitting tube 2 and infrared receiving tube 3 pass through signal connecting wire 4 and 10 phase of singlechip controller in circuit board 5
Connection, singlechip controller 10 are connected with the intracorporal light emitting diode 9 of the machine that is similarly disposed at and buzzer 8, and circuit board 5 drives infrared
Transmitting tube 2 detects, then received signal is sent back circuit board 5 by infrared receiving tube 3 and is judged by circuit board 5, when empty bottle then by
Light emitting diode 9 and buzzer 8 realize sound-light alarm.
The singlechip controller 10 has been internally integrated CPU11, voltage comparator 12, ADC13, interruption system 14 and timing
Device 15.
The circuit board 5 is connected by button lithium electricity with the lithium coin cells 6 being arranged in body rear end detachable battery seat 7
Pond 6 provides electric power.
The infrared transmitting tube 2 can be blocked when there is drop to fall, to export faint electric signal, be input to monolithic
The conditioning of voltage comparator 12 inside machine controller 10 is at the fast pulse signal of drop.
The singlechip controller 10 just controls 9 light-emitting flash of light emitting diode after detecting infusion, control buzzing
Device 8 sends out prompt tone, reminds user to pay attention to by strong sound and light program.
The light emitting diode 9 can be used as fast indicator is dripped, flashing speed with the velocity variations that drop is fallen and
Variation, then flashing is fast fastly for transfusion speed, and then flashing is slow slowly for transfusion speed, and infusion does not flash then when stopping.
The present invention can judge drop speed by singlechip controller 10 in the state of perfusion tube dropping funnel position detection drop,
