The specific embodiment
Below in conjunction with drawings and Examples this utility model is further specified,
This transfusion monitoring system is provided with the cavity housing 5 of one with it in the tube for transfusion hard that is connected with medicated bag 74 bottoms of popping one's head in, and as shown in Figure 2, is provided with an impeller 6 in the housing 5, and the blade of impeller 6 one sides is positioned at tube for transfusion.These cavity housing 5 outer suit one signal transceivers 3, as shown in Figure 3, signal transceiver 3 mainly comprises housing and is installed in infrarede emitting diode 31, infrared sensor 32 on the housing.Infrarede emitting diode 31, infrared sensor 32 place the both sides of impeller 6 respectively, and the corresponding with it transparent window 51 that is provided with on impeller housing, the light that sends of infrarede emitting diode 31 can pass the transparent window 51 of impeller housing to infrared sensor 32 like this.Seal between housing 5 and the tube for transfusion, prevent the outside seepage of medicinal liquid.
When the medicinal liquid of 7 li of the medicated bags liquid-transport pipe-line through hard probe 4 flows out, medicinal liquid can impeller 6 rotate.When impeller 6 rotates, during light that infrarede emitting diode 31 sends and impinge upon on the infrared sensor 32 of another side, the time and by the blocking-up of the blade of impeller 6, so infrared sensor 32 has just received light pulse.Its pulse frequency is relevant with the rotating speed of impeller 6, thereby further the flow velocity with medicinal liquid is relevant.Signal transceiver 3 is built-in with decoding chip, this decoding chip reads the light pulse of infrared sensor 32, and it is converted to binary data, be transferred to the liquid crystal display 33 that is arranged on the signal transceiver surface of shell, binary digital signal is converted to the decimal scale liquid crystal digital by liquid crystal display, and the rotating speed that reflects impeller immediately, accurately is that medicinal liquid " drips speed ".
Report to the police in the ward: in the signal transceiver 3 the sounding modules being installed is warning circuit, and when the impeller stall, numeral is during for " 0 " or when numerical value is set, and sound gives the alarm.Also can set drip a fast scope according to conditions of patients, when exceeding this scope, or reach when setting amount of infusion, it is too fast or cross and send warning when slow to drip speed.Described signal transceiver is provided with an alarm switch, and alarm switch connects and the control warning circuit.Whether the signal transceiver audio alert can be set as required and enable, and when infusing as the critical patient, is unsuitable for noisy sound and occurs, and just closes alarm switch, and warning circuit is not sounded.
NO monitoring: as shown in Figure 1, the transfer of data of the decoding chip that signal transceiver is built-in is to digital signal processor, and the data layout again that digital signal processor transmits each signal transceiver sends the total computer to the form of data splitting.Microcomputer is installed corresponding software, reads these data, and reduction at each signal transceiver under one's name, helps medical personnel to understand " dripping speed " situation of each transfusion device in real time.
Because the liquid of some, impulsion impeller operation week number is fixed, that is to say that it is fixed that signal transceiver transmits binary system quantity, thereby, can judge accurately that certain time transfusion person imports remaining liq quantity in amount of fluid and the medicated bag according to signal transceiver transmission binary system number change situation.These can both reflect in computer visually, not only intuitively but also convenient.Be provided with alert program in the computer, when certain needs of patients in the infusion process adds that the residue medicine is a small amount of in medicine or the medicated bag, the alarm computer prompting.When certain patient's liquid stop dripping or bottle in liquid when dripping off, alarm computer is also quoted bed label.Medical personnel can be in time queueing problem efficiently, avoid conscientiously causing unnecessary misery to patient, effectively improve medical personnel's work efficiency and medical treatment level.
Signal transceiver and digital signal processor connected mode one: be connected available employing wired connection mode between signal transceiver and the digital signal processor.As shown in Figure 4, wired connection is to be connected by cable 9 between decoding chip and the digital signal processor of described signal transceiver.
Signal transceiver and digital signal processor connected mode two: also can adopt the wireless connections mode between signal transceiver and the digital signal processor, as shown in Figure 5, in the relative patient's head of a bed of signal transceiver body of wall one side, an infrarede emitting diode 10 is installed, pulse current with the infrared sensor in the signal transceiver 32, lead to this infrarede emitting diode 10 after drawing one tunnel amplification, this diode will be according to the current impulse light-emitting flash, and frequency is identical with pulse current.It is relative with patient's head of a bed body of wall that signal transceiver is installed infrarede emitting diode 10 1 sides, in patient's head of a bed body of wall and the relative position of diode 10 levels, an infrared sensor 11 is installed, these pick off 11 usefulness cables 9 link to each other with NO digital signal processor and computer, can utilize the ward to have alarm circuit now.------infrared sensor---digital signal processor of the NO---computer of NO of sick bed front end body of wall installation of infrarede emitting diode outside the signal transceiver that when liquid impulsion wheel rotation, will produce following signal transduction process: the built-in infrared sensor of signal transceiver.By computer each transfusion device is monitored in real time.Infrarede emitting diode 10 peripheries that are installed in the signal transceiver outside are provided with baffle plate and shut out the light, and make emission light directly to metope, influenced by it in case close on sick bed, misrepresent deliberately phenomenon.
Except that above-mentioned wireless connections mode, also can use other radiotechnics or Bluetooth technology, carry out the information transmission, can adopt known equipment.But weak point is, the cost height, and the signal transceiver power consumption is bigger, uses uneconomical.
