The following embodiments of the present invention provide a kind of wireless multi-parameter module, can be to radio that wireless sensor is sent out Wave signal is received and is passed to patient monitor, to overcome in the prior art wireless measurement equipment can not be linked into patient monitor Technological deficiency, make patient monitor that there is wireless receiving function, realize to the wireless sign monitoring effect of patient.Multi-parameter monitor Important patient information can be provided for medical clinic applications, by various functions module, can detect in real time human body electrocardiosignal, The important parameters such as heart rate, blood oxygen saturation, blood pressure, respiratory rate and body temperature realize that the supervision to each parameter is alarmed.Information storage And transmission, it is a kind of important equipment of monitoring patient.Excessive data line can be right in multi-parameter module use currently on the market The operation of doctor forms very big interference and obstacle, present example solve the problems, such as this.

Multi-parameter monitor in clinical application mainly handles two parts by data acquisition module and embedded data and forms. Data acquisition module is mainly used to complete the acquisition process of electric signal, and embedded data processing unit then mainly completes the meter of data The parts such as calculation and display.By taking blood oxygen signal as an example, in order to measure the blood oxygen signal of human body, the light that blood oxygen probe is sent is double Infrared light, the wavelength of the double infrared lights intermittence during oxygen saturation monitor change.Pass through double infrared light wavelength Variation, to improve the accuracy of oxygen saturation monitor, for example wavelength is 660nm and 905nm.As shown in Fig. 2, 660nm and 905nm Two beam infrared lights in solid black lines rising edge moment opening, closing, are opened respectively so as to form 660nm, 660nm is closed, 905nm is opened, 905nm closes four states.Therefore, data acquisition module need control blood oxygen probe two wavelength be The light-emitting LED sequential according in Fig. 2 of 660nm and 905nm is opened successively, then according to the when ordered pair photoelectric receiving tube in Fig. 2 It is sampled, processing etc. is then also digitized to the signal of photoelectric receiving tube, finally digitized a series of acquisition Data be sent to embedded data processing unit, more advanced calculation processing and display are done by embedded data processing unit. And the signals such as blood pressure, cardiac electrical acquisition are similar, and data acquisition module is required for complete the acquisition and processing of signal, or even will also be into Row timing control carries out data acquisition.Multi-parameter module described in this patent is above-mentioned data acquisition module.Due to mesh Preceding multi-parameter monitoring has developed many decades, wherein the acquisition to many medical signals is all highly developed.Therefore, exist at present During the transformation and upgrade of patient monitor, it will usually monitor module be designed to ripe module, for different model difference The patient monitor of demand only needs to change embedded data processing unit, therefore this patent proposes, wireless by designing one Multi-parameter module, to only carry out multi-parameter module a replacement, can allow conventional monitor have wireless collection measurement work( Energy.

Fig. 1 is the application of more ginseng patient monitors wireless in the embodiment of the present invention, and multi-parameter module is as more ginseng patient monitors One component.Vital sign data for receiving wireless sensor acquisition.As shown in fig. 1, multi-parameter monitor can receive The quantity of wireless sensor can be a variety of, it is not limited to it is a kind of.Including temperature, blood oxygen, invasive blood pressure, non-invasive blood pressure Deng.In the present embodiment, due to passing through wireless communication between wireless sensor vital sign sensors and wireless multi-parameter module Number carry out data transmission, the data or digitized data that actually wireless multi-parameter module receives, thus meaning The function that wireless multi-parameter module does not have data acquisition substantially, data acquisition is mainly passed by the vital sign of front end Sensor is completed, middle converting interface of the wireless multi-parameter module mainly as data.

Wireless multi-parameter module can identify the data of vital sign sensors acquisition according to the data content of reception, Vital sign is medical terminology, is the performance of basic human body physiological function.Refer to healthcare givers when carrying out medical treatment, in order to assess disease The basic physiological status of people, in physical examination, it is necessary to the basic function of inspection.Its range is very extensive, normally comprises the heart Electricity, pulse, blood pressure, breathing, body temperature, blood oxygen saturation etc..Vital sign is the important sign for indicating vital movement and existing with quality As being one of the big event for assessing body, they are the pillars for maintaining body normal activity, indispensable, no matter which Xiang Yi Often also result in serious or fatal disease.Vital sign data is monitored with regard to particularly important, vital sign sensors specifically include The wireless vital sign sensors sensor such as electrocardio, blood oxygen saturation, blood pressure, breathing and body temperature, patient monitor are different by receiving Wireless vital sign sensors take Different treatments.The operation principle of common vital sign data processing is as follows：Blood Oxygen saturation (SpO2) measurement is that the fingerstall that will pop one's head in is fixed on patient's finger tip nail matrix, using finger as the saturating of splendid attire hemoglobin Bright container is measured and is passed by the light of tissue bed using the feux rouges of wavelength 660nm and the near infrared light of 940nm as light source is injected Intensity is led, to calculate hemoglobin concentration and blood oxygen saturation.It can be used for the blood oxygen monitoring of various patients.It is generally acknowledged that SpO2 is just 94% should be often not less than, for for hypoxgia below 94%.There is scholar by SpO2<90% is set to the standard of hypoxemia, and recognizes Can then to have error when reachable ± 2%, the SpO2 of accuracy is less than 70% when SpO2 is higher than 70%.Clinically our once logarithms The SpO2 numerical value of example patient, is compareed with arterial oxygen saturation numerical value, it is believed that SpO2 reads the work of breathing that can reflect patient Can, and reflect the variation of arterial blood oxygen to a certain extent.Postoperative patients after chest surgery removes single cases clinical symptoms and numerical value not Symbol need to be made outside blood gas analysis, conventional to be monitored using detecting sphygmus and blood oxygen saturation, can be provided for clinical observation change of illness state significant Index avoids patient and takes a blood sample repeatedly, also reduces the workload of nurse.The biological Electrical change of heart itself by heart around Conductive tissue and body fluid reflect onto body surface, so that parts of body is also all occurred in each cardiac cycle regular Electrical change activity.Measuring electrode is placed on to the cardiac electric change curve that certain position of human body surface records out, is exactly The electrocardiogram (being indicated with ECG) clinically routinely recorded at present.The waveform occurred in each cardiac cycle on normal ECG Curve change is regular, these waveforms are referred to as P waves, QRS wave, T waves and also go out sometimes after T waves by regulation in the world An existing small U wave.In addition, a normal electrocardiogram further includes phase, PR sections and ST sections between phase (or phase between PQ), QT between PR. P waves represent the wave of depolarization in atrium, and QRS wave represents the wave of depolarization of ventricle, and T waves represent the repolarization wave of ventricle.The phase represents by sinus between PR Room knot generates excited via atrium, atrioventricular junction and atrioventircular bundle arrival ventricle, and ventricle is caused to start the excited required time, Phase reflection sequences of ventricular depolarization and process of repolarization total time, also represent the electric contraction time of heart, ST sections represent each portion of ventricle between QT Divide and fully entered depolarising state, there is no potential difference presence, curve to be restored to baseline level again between ventricle each section.Take care It is dirty because when ischemic is impaired or necrosis, the variation of electrocardio-activity can be correctly reflected on electrocardiogram in time, show each waveform Anomalous variation and progressive evolution process, for doctor provide diagnosis arrhythmia cordis, ventricular hypertrophy, acute ischemia, myocardial infarction The reliable basis of equal heart diseases.People's normal body temperature compares homeostasis, but it can be changed because of a variety of factors, but variation has one Set pattern rule.Normal person's auxillary temperature is 36~37 degree, and oral temperature is 0.2~0.4 degree higher than oxter, and rectal temperature is again than oral cavity temperature It spends 0.3~0.5 degree high.The body temperature of normal person slightly fluctuates in 24 hours, is no more than 1 DEG C under normal circumstances.Under physiological conditions, Morning is slightly lower, slightly higher after afternoon or movement and feed.Old human temperature is slightly lower, and women is slightly higher before menstrual period or when gestation.Body The chemical energy that interior nutrient metabolism releases, wherein 50% or more is used to maintain body temperature in the form of thermal energy, remaining is insufficient Then load is converted by energy and is utilized in ATP 50% chemical energy, finally also becomes thermal energy, and with the heat that maintains body temperature Together, underlying body layers are transmitted to by blood circulation and distributed in external.Therefore, body makes under the regulation and control of thermoregulatory mechanism Exothermal process and radiation processes are in balance, i.e. body heat balance, maintain normal body temperature.If the quantity of heat production of body is more than heat dissipation Amount, body temperature will increase；Heat dissipation capacity is more than quantity of heat production, and then body temperature will decline, until quantity of heat production and heat dissipation capacity re-fetch balance Shi Caihui makes body temperature stablize in new level.The generation promotion blood of blood pressure flows in the blood vessels and the pressure of vasoactive wall Referred to as blood pressure, for referring generally to arterial pressure.When ventricular contraction, the highest pressure of intra-arterial is known as systolic pressure；When ventricular diastole, The minimum pressure of intra-arterial is known as diastolic pressure.Systolic pressure and the difference of diastolic pressure are pulse pressure.Blood pressure is the weight for weighing cardiovascular function Want one of index.When systolic pressure and diastolic pressure are below lower limits of normal (90/60 millimetres of mercury), it is considered as being acute Peripheral circulatory failure, scheming infarction, heart failure, acute heart tamponade etc..When hypertensive encephalopathy or increased intracranial pressure, blood pressure Often more than 200/120 millimetres of mercury.Normal value normal adult's systolic pressure of blood pressure is 12~18.7kPa (90~140mmHg), 8~12kPa of diastolic pressure (60~90mmHg).Newborn's systolic pressure be 6.7~8.0kPa (50~60mmHg), diastolic pressure 4~ 5.3kPa (30~40mmHg.After 40 years old, systolic pressure can increase with the age and be increased.39 years old or less systolic pressures<18.7kPa (140mmHg), 40~49 years old<20kPa (150mmHg), 50~59 years old<21kPa (160mmHg), 60 years old or more<22.6kPa (170mmHg)。

Specifically, in the present embodiment, the sensor type that wireless multi-parameter module can receive includes electrocardio, blood oxygen A variety of wireless sensors such as saturation degree, non-invasive blood pressure, breathing and body temperature, it is generally the case that electrocardio, temperature, blood oxygen and blood oxygen quilt Referred to as four big vital signs of human body.But the implementation of this patent be not intended to limit a wireless multi-parameter module receive it is a variety of Wireless sensor, it is one such to be that single wireless module only receives, and then multiple wireless little modules combine shape At a big module.

Further, to the either critically ill patient of operation patients clinically, depth of anesthesia, invasive blood pressure, CO2 concentration It is also the important indicator that multi-parameter monitor is monitored with pain depth etc., therefore, in the other embodiment of this patent, nothing The type that the multi-parameter module of line is also equipped with reception includes that depth of anesthesia, invasive blood pressure, CO2 concentration and pain depth etc. wirelessly pass One or more of sensor.

Further, in the present embodiment, wireless multi-parameter module can identify same vital sign sensors Multiple same type of sensor.Include mainly needing to carry out the life sign measurement etc. at multiple positions in clinical application, in the present embodiment In, wireless multi-parameter module has the ability for receiving two temperature sensors, and can be with two sensors of automatic identification It is different.

Specifically, in the present embodiment, wireless multi-parameter module adaptation is the multi-parameter monitor for stepping auspicious T8, the prison Shield instrument has the function of that display two-way temperature, the multi-parameter module that this is wireless, will by the data of two temperature sensors of reception Data are sent to patient monitor, and data are displayed on above two channels of patient monitor, while not being generated mutually between two temperature Interference.

Under normal conditions, the matching of radio transmission apparatus is a critically important job, which can ensure multiple wireless In the case that transmission device works at the same time, the wireless vital sign sensors and the wireless multi-parameter module still can be with Accomplish to correspond, data transmission not crosstalk from each other, the different wireless multi-parameter modules respectively receives respectively The data that the corresponding wireless vital sign sensors are sent out.Generally in the case where possessing display equipment, according to aobvious Show the uniqueness ID for the different radio vital sign sensors that equipment is shown to judge.But to the automatic of the equipment without display Matching is difficult to realize.In the present embodiment, under normal circumstances, the wireless multi-parameter module and the Wireless vital body It is at intervals to use to levy sensor, and under normal circumstances, the wireless multi-parameter module receives the wireless life The signal strength for ordering condition sensor transmitting signal is not higher than -20dBm.Only in the wireless multi-parameter module and the nothing In the case that line vital sign sensors abut, the wireless multi-parameter module receives the wireless vital sign sensors The signal strength of transmitting signal can just be higher than -20dBm.So in the present embodiment, when the wireless multi-parameter module is not having When having the specified wireless vital sign sensors, if detecting the signal of the wireless vital sign sensors transmitting signal Intensity be higher than -20dBm, that is, judge at this time be Auto-matching state, automatically using the wireless vital sign sensors as specify Wireless vital sign sensors, and the uniqueness ID of the module is recorded, the wireless vital sign sensors are bound later, Only receive the data of this wireless vital sign sensors.

Specifically, in the present embodiment, the multi-parameter monitor for stepping auspicious T8 has a 1 road ECG channel, the 1 road channels SPO2, and 1 Road non-invasive blood pressure channel, 2 tunnel temperature channels, 1 channels BIS and 1 CO2 concentration channel, therefore, wireless multi-parameter mould The quantity of the at most receivable vital sign sensors of block is also only limited to this.In the present embodiment, it is passed in multiple wireless ECG Sensor there are when, wireless multi-parameter module need for the first time identification receive which wireless ECG sensor data, to protect Card data do not get muddled (namely normal described binding).The transmission power for the wireless ECG sensor that the present embodiment uses 20dBm, under normal circumstances, due in the range of within the decaying in air, especially 1 meter of range transmission power target rapidly Decaying, the wireless signal strength that wireless multi-parameter module receives are not higher than -30dbm, when the sensor is close to wirelessly more When parameter module (especially when within 10cm), the wireless signal strength that wireless multi-parameter module receives is 0dbm.This When wireless multi-parameter module just think to belong to identification maneuver at this time, automatically record equipment uniqueness ID, and only connect afterwards The data for receiving the equipment record new equipment, and bind again again after having new equipment identification.

Specifically, for any one electronic system, first have to solve is exactly the supply problem and power supply of power supply Matching the problems such as.Further, in the present embodiment, this wirelessly provides power supply by patient monitor, ensures wireless normal work. As previously mentioned, patient monitor is usually made of multi-parameter module and embedded data processing unit, the phase that different patient monitors uses Same multi-parameter module, therefore the interface section of different patient monitors and connection size are substantially also identical.Specifically, exist In the present embodiment, auspicious interface section advanced in years is as shown in Figure 3, and 601 be to step auspicious T8 multi-parameter monitors, and the 602 of the lower left corner is more The interface of the multi-parameter module of parameter patient monitor, the 603 of left side is wireless multi-parameter module.The circular interface of two of which is Two infrared receiving/transmission interfaces, are the data-interfaces of multi-parameter module 603 and multi-parameter monitor 601, and two rectangular interfaces are The interface to external power of multi-parameter monitor 601, metal material.When multi-parameter module 603 is inserted into multi-parameter monitor 601 When specified interface position 602, infrared interface is directly aligned, and the rectangular metal material on both sides is in direct contact, to by joining more Number patient monitor 601 completes wireless 602 power supply.It further, then directly will be more in the another embodiment of this patent The power supply of parameter module is external, to wireless multi-parameter module for power supply and a kind of solution in such a way that outside individually powers Scheme.

Fig. 4 is that wireless parameter module is made of radio receiving unit and data processing unit.Wherein radio receiving unit connects The data of vital sign sensors are received, and send the data to data processing unit, the connection of data processing unit one end wirelessly connects Unit is received, the data of radio receiving unit are received, other end passes data to patient monitor and carries out data processing.Wherein data Pass to patient monitor and use wireless mode, be easily installed and avoid it is wired patch unstable cause signal transmission wrong.
