The beneficial effects of the invention are as follows：A kind of voice entry system of intelligent control fluid delivery apparatus provided by the invention, doctor
Shield personnel only need to be by handheld terminal typing doctor's advice transfusion plan, and the voice signal is after sound identification module identifies with electric signal
Output, finally reaches fluid delivery apparatus in the form of text information, and fluid delivery apparatus is embodied as clinical patients according to text information and inputted
Decoction or nutrient solution.Therefore, compared to being manually entered, present invention reduces infusion parameters error and the brand and specification of consumptive material
Select inappropriate probability, reduce because infusion precision is inaccurate and caused by surprisingly cross medicine amount liquid impact or very few decoction wind
Danger, while the setting time of infusion parameter is saved, the risk for avoiding delay from infusing, medical personnel's time can be generally saved,
Mitigate medical personnel's burden, so as to improve medical personnel's efficiency.
Brief description of the drawings
Present pre-ferred embodiments are provided below in conjunction with the accompanying drawings, to describe embodiment of the present invention in detail.
Fig. 1 is the voice entry system structured flowchart of the present invention；
Fig. 2 is the workflow diagram of the sound identification module of the present invention.
Embodiment
Reference picture 1, a kind of voice entry system of intelligent control fluid delivery apparatus, including fluid delivery apparatus 3, the and of handheld terminal 1
Doctor's advice transfusion plan is simultaneously sent to sound identification module by sound identification module 2, the voice typing doctor's advice transfusion plan of handheld terminal 1
2, doctor's advice transfusion plan is exported as electronic signals after the identifying processing of sound identification module 2, and electric signal is transmitted by medium
It is loaded under to fluid delivery apparatus 3 and in the form of text information in fluid delivery apparatus 3, fluid delivery apparatus 3 is embodied as facing according to text information
Bed patient inputs decoction or nutrient solution.
Specifically, medical personnel can download the APP softwares of the voice entry system of the present invention by handheld terminal 1, so
After log in the APP softwares, directly talked with by voice with handheld terminal 1, so as to typing doctor's advice transfusion plan, the APP software branch
Different language and dialect are held, doctor's advice transfusion plan is numbered including fluid delivery apparatus 3, patient information, infusion parameter, consumptive material brand and rule
Lattice etc., then handled by sound identification module 2 and be converted into electric signal, can be Wi-Fi or broadband network by medium
Deng, reach on fluid delivery apparatus 3, finally synchronously downloaded in the form of text information corresponding in fluid delivery apparatus 3, now medical care people
Member doctor's advice transfusion plan can be reaffirmed on handheld terminal 1, if errorless, press start key, then fluid delivery apparatus 3 start for
Patient fluid infusion；Therefore, compared to being manually entered, present invention reduces the brand and specification of infusion parameters error and consumptive material be not proper
When probability, reduce because infusion precision is inaccurate and caused by surprisingly spend medicine amount liquid impact or very few decoction risk, same to time
The setting time of infusion parameter is saved, the risk for avoiding delay from infusing, can generally save medical personnel's time, mitigates medical care people
Member's burden, so as to improve medical personnel's efficiency.
Wherein, referring to Figures 1 and 2, sound identification module 2 includes front-end module 21 and rear module 22, front-end module 21
For pre-processing voice signal and establishing model library, model library includes sound model storehouse and language model storehouse, and rear module 22 is used
Match in identification voice signal after pretreatment and with model library；Rear module 22 also includes an adaptive feedback mould
Block, self study can be carried out to the voice of user, so as to carry out necessary correction to sound model and language model, with further
Improve the accuracy rate of identification.
Wherein, pretreatment of the front-end module 21 to voice signal includes sampling, overcomes aliasing filtering, end-point detection, removal
Difference of pronouncing and reduction ambient noise, sampling refer to that discrete component is extracted from continuous voice signal to be made individually to parse, aliasing
Refer to the phenomenon that the high-frequency signal in voice signal folds into low-frequency range, false frequency content occurs, overcome aliasing filtering can
Aliasing frequency component is further reduced, the purpose of end-point detection is to look for suitable voice unit starting point and ending point, with
One section of clearly sampled signal is obtained, the purpose for removing pronunciation difference is to try to reduce the accent because of user or custom etc. of speaking
Difference and the error brought, the main purpose for reducing ambient noise are to remove unnecessary Jing Yin and non-talking sound, pass through pretreatment
The substantive characteristics of voice signal can more completely be reflected.
Wherein, the step of front-end module 21 establishes model library is that carrying out feature to pretreated voice signal first carries
Take, then the feature of extraction be trained, finally establish model library according to pre-defined rule, the feature of extraction is trained be
Completed under off-line state；The specific method of training is：By collecting the feature of a large amount of voice signal samples, compare to obtain difference
The foundation characteristic of species, different voice signals is also just correspond to, then the data of these foundation characteristics are arranged, generate mould
Formula storehouse；Pre-defined rule is：, will not herein by the voice signal with same or like foundation characteristic point in same model class
In the range of voice signal continue to be compared to each other, by that analogy, all voice signal samples are classified.
Wherein, rear module 22 is identified including identification language message coding and utilized to pretreated voice signal
Distinguish discrete symbol and represent voice signal, and analysis grammatical and semantic and language specification；To the language message in voice signal
Coding is carried out according to the time change of amplitude spectrum, and because voice can be read, that is to say, that voice signal
Can do not consider speaker speak reception and registration the information content on the premise of with it is multiple have distinctive, discrete symbol come table
Show, and the interaction of voice is a cognitive process, it is impossible to split off to come with grammer, semanteme and language specification etc., so
Need to analyze grammatical and semantic and language specification.
Wherein, matched with model library in extraction feature and model library including voice signal more after pretreatment
The similitude between feature is stored, to match the recognition result of speech output signal, this identification process is completed online, energy
Identical with the feature of a pretreated voice signal or the most approximate contrast signal is enough matched, and with the shape of electric signal
Formula exports to next stage.
Preferably, handheld terminal 1 is mobile phone, flat board or computer；Handheld terminal 1 is typically carried with by medical personnel, band
There are Wi-Fi wireless network cards, central monitoring server can be remotely accessed by hospital Wi-Fi or 4G, can be any with real-time display
The basal conditions for the treatment of unit, and receive warning message and carry out jingle bell or/and vibration prompt, while medical personnel can lead to
Infusion process and physiology monitoring-information that handheld terminal 1 observes patient are crossed, in order to understand treatment at any time.
Preferably, fluid delivery apparatus 3 includes infusion pump, syringe pump, nutrition pump, blood transfusion apparatus and target control pump.
Presently preferred embodiments of the present invention and general principle are discussed in detail above content, but the invention is not limited in
