Embodiment
With reference to illustrative example, the present invention is described in detail.Following examples will be helpful to the technology of this area
Personnel further understand the present invention, but the invention is not limited in any way.
A kind of structure chart of the transfusion monitoring device provided as shown in Figure 1 for the present invention, including supporter, woven hose are fixed
In supporter, woven hose both sides are located in transfusion drip tube is respectively arranged with light-beam transmitter 1 and photosensitive at ullage position
Element arrays 2 so that the light of the directional transmissions of light-beam transmitter 1 can be by light-sensing element array after being reflected through liquid level in transfusion drip tube
2 receive；Turbidity acetes chinensis mould is provided with position below liquid level in transfusion drip tube and with the homonymy of light-sensing element array 2
Block 3 so that the light of the directional transmissions of light-beam transmitter 1 can be by turbidity acetes chinensis module 3 after being reflected through liquid level in transfusion drip tube
Receive；Light-beam transmitter 1 described in the present embodiment, light-sensing element array 2 and turbidity acetes chinensis module 3 are connected with single-chip microcomputer.
Supporter bottom, which is additionally provided with woven hose in chute and motor 4, chute, is provided with moveable pressure head 5,
The motor 4 and pressure head 5 are connected by gear and rack, and motor 4 is connected with single-chip microcomputer, driven by single-chip microcomputer controlled motor 4
Pressure head 5 is slided in chute, and transfusion catheter, control drop speed are extruded to some extent.
Can be set in supporter has dropper detect tank, national standard of the size based on transfusion device, in connection dropper detect tank
Under be provided at both ends with conduit trough, the diameter for being smaller than transfusion catheter of conduit trough, it is to avoid dropper horizontal direction departs from, from causing
Transfusion monitoring device can be hung with transfusion device, it is adaptable to which pole type Infusion support and ceiling suspension type transfusion hook etc. are a variety of
Actual conditions.
Supporter back is additionally provided with clamping device, and transfusion detection device is clamped on transfusion pole.
Light-beam transmitter 1 is polychromatic light with fixed angle directional transmissions convection light, light, only with turbidity during polychromatic light
The Chromatic sensor of acetes chinensis module can just detect the different color of liquid.
Liquid level position in transfusion drip tube adjusts liquid level to OK range by medical personnel by extruding dropper.
Light-sensing element array 2 can be received through the reflection light that liquid level reflection is obtained in dropper, detected according to photo-sensitive cell
Hot spot vibration frequency and position record drop speed and liquid level, and the facula position that recorded is sent to single-chip microcomputer.Work as light
During the big ups and downs of spot position, it is judged as that drop drips, thus calculates drop speed；The facula position that light-sensing element array recorded is one
When unchanged in the section time, it is judged as that decoction is totally lost.Decoction total amount is obtained by manually setting or reading patient medical record during beginning,
Estimated be totally lost the time can be calculated according to drop speed in the course of the work.
Turbidity acetes chinensis module 3 is acceptable through the refracted light that liquid level refraction is obtained in dropper, and its essence is a kind of special
Different high-definition camera, photo-sensitive cell is ribbon, and traditional photo-sensitive cell is circular or rectangle, such as magazine photosensitive core
Piece, photo-sensitive cell of the invention is strip, and length is more than width several times.Single-chip microcomputer by the hot spot degree of dispersion that detects and
It is photochromic to calculate turbidity, aberration coefficient correlation, and the decoction data that wireless module is downloaded in advance are contrasted, and judge decoction species
And quality.When turbidity acetes chinensis module 3 detects data and inconsistent patient medical record decoction normal data, it is judged as decoction
Species or abnormal quality.
The display content of display module 6 includes current decoction drop speed, remaining amount of liquid medicine, remaining time, control model and report
Alert information.
Alarm module 8 is when data that turbidity acetes chinensis module 3 is gathered are mismatched with terminal decoction data and transfusion
Liquid level is less than detection range alarm in dropper.
Single-chip microcomputer is uploaded by wireless transport module to nurse station terminal includes working condition, decoction drop speed, remaining decoction
Amount, expected deadline and patient calls' command information, and control instruction controlled motor 4 is received with the control transfusion of dynamic head 5
Drop speed, and block woven hose when alarm module 8 is alarmed.In addition, single-chip microcomputer simultaneously also in real time receive from Remote with
And the control command of key-press module 7, realize the drop speed function such as control, parametric calibration and calling manually.
Key-press module 7 at least includes giving an order：Clear command, i.e. decoction be totally lost when changing liquid by medical personnel input it is clear
Zero instruction, removes counter data；Medicine liquid volume selection instruction, is manually entered the body of actual fed when changing liquid by medical personnel
Product；Sound all clear instruction, the alarm of alarm module can be released manually.
The Computing Principle of the present invention is as follows：
Read each minimum and maximum seat for receiving optical signal photosensitive unit in each sampling time light-sensing element array
Mark.
Judge whether decoction is used up (or pipeline is obstructed)：Judge whether coordinate is stable within certain time (more than 2s)；If
Stable then illustrate liquid surface static, decoction is used up or pipeline is obstructed, and sends alarm.
Judge liquid level position：A period of time internal coordinate average (i.e. on reflected light path a bit) is obtained, due to each liquid
Face position necessarily corresponds to unique reflection light light path, therefore the mapping table drawn according to testing in advance maps out actual liquid level and sat
Mark.
Judge that transfusion speed and expection are totally lost the time：When coordinate exceedes a certain value that experiment is determined, illustrate liquid surface wave
It is dynamic violent, it is judged as that drop drips, the count value n=n+1 of counter.The time interval of counter+1 twice is read, is two
The time interval T (s) of drips is dripped, each dropping liquid drop volume average value V0 (mL) determined according to experiment, you can it is determined that drop
Fast Q (mL/min)=V0*60/T., can according to (can be set by terminal remote, monitor by key assignments) cumulative volume V of setting
To show that expection is totally lost the time：T=V/Q (min).
Judge decoction species：The image that reading liquid level bottom turbidity acetes chinensis module 3 is obtained is sent to terminal (nurse station
Computer), terminal can access medical data base, find the decoction that patient is using, recall what lane database was drawn by testing
Decoction image, two images are contrasted, because different decoctions has different turbidity and aberration, so as to judge reality
Whether whether the decoction that border is used is consistent with the decoction that should be used or go bad.
