Description
TEMPERATURE MEASUREMENT SYSTEM
Field of the Invention
This invention relates to a system for measuring temperature.
Background of the Invention
Each year, millions of patients suffer from the effects of unintended hypothermia. The operating rooms remain cold and the surfaces of the operating tables reflect the ambient temperature before the arrival of the patient. Patients are discovered, surgical sites are opened and cold fluids are often injected. If patients undergoing major general and regional anesthesia are not heated during surgery, they may suffer from unintended hypothermia. The problems of non-deliberate hypothermia are especially acute with major abdominal or orthopedic surgery as they tend to involve large incisions that expose the internal organs and tissue of the patient to the cold operating room.
Hypothermia can happen quickly. Frequently, the patient begins to lose body temperature during pre-operative preparations and arrives in the operating room below the temperature
normal. The anesthetic agents themselves interfere with the body's ability to regulate temperature and certain types of patients are more likely than others to lose body heat. As a result, patients are frequently transferred to recovery in a hypothermic state. In the unit of care after anesthesia, coldness is one of the most frequent complications of patients. In a survey of post-operative nurses, heat was cited as the main comfort concern followed by pain. Warm blankets are piled on the patient to relieve them. effects of hypothermia, increasing the amount of time elapsed in recovery.
Hypothermia has a variety of detrimental effects and a relatively small decrease in core temperature can result in major complications or even death. These detrimental effects are well documented and include:
1. increases in infections of surgical sites;
2. increased blood loss;
3. Increases in the number of cardiac events. { including myocardial ischemia and ventricular tachycardia); Y
4. a prolonged and altered effect of
drugs used during anesthesia.
The heating system for the patient LMA
PerfecTemp "has been designed to help maintain the patient's normal temperature before, during and after surgery for both pediatric and adult patients, it is lightweight, durable and easy to clean, since the system does not use a blanket, there is no problem with surgical access, it is also radio-translucent, so it will not interfere with X-rays, and it is silent, so it will not distract doctors.
The LMA PerfecTemp patient heating system comprises an electric heating element interposed between layers of foam to form a hot mattress pad.The heat is gently transferred to the patient in a conductive manner, the most efficient method of heat transfer, With conductive heating temperatures selected by physicians, the type of foam used makes pressure reduction possible, which helps to prevent pressure ulcers (pressure reduction properties are effective for patients up to 225 kg / 500 lbs. weight) .
Clearly for the LMA PerfecTemp ™ patient heating system, and other heating systems for the patient's hot mattress pads (such as mattress pads that use
water-based heating elements or gel to heat the patient), operate efficiently it is necessary that the temperature of the mattress pad be monitored to ensure that a normal temperature is maintained.
Summary of the Invention
The present invention offers a safe and accurate temperature monitoring system that is suitable for use with a hot mattress pad.
Description of the invention
According to a first aspect of the present invention, there is provided a temperature measurement system for use with a hot mattress pad, hot mattress pad which comprises a heating element, the system comprises at least three sensors of temperature and at least one converter module, at least one of the temperature sensors is adapted to be fixed to the heating element, at least one of the temperature sensors is adapted to be fixed to the pad and therefore less one of the temperature sensors is adapted to be fixed to a patient that is located on the pad. This system allows the
The temperature of the patient and the pad are monitored simultaneously and ensures that the heating element does not overheat.
The three temperature sensors can be connected to a single converter module, or multiple converter modules can be used with some temperature sensors connected to a first converter module and others connected to a second converter module. For example, at least the temperature sensor adapted to be attached to the heating element and at least the temperature sensor adapted to be fixed to the pad may be connected to a first converter module and at least the adapted temperature sensor. to be fixed to a patient it can be connected to a second converter module. In embodiments using this array of temperature sensors and converter modules, the first converter module may be located within a hot mattress pad while the second converter module may be separate from the hot mattress pad.
In use, at least the temperature sensor attached to the heating element acts as a safety sensor. In the absence of a patient, the two temperature sensors adapted to be fixed to the pad and
adapted to be fixed to the patient, they do not provide any temperature feedback and in this way if the heating element were turned on it could overheat. However, because at least one temperature sensor is attached to the heating element, the temperature of the heating element itself is monitored and the heating element can be prevented from reaching excessively high temperatures.
In use, at least the temperature sensor fixed to the pad will commonly be located on the outer surface of the mattress pad or on the lower surface of the mattress pad surface cover, but below the surface cover of the mattress pad. mattress pad (on which the patient is placed). In the context of the invention, being "adapted to be fixed to the pad" comprises both being adapted to be fixed to the pad itself and being adapted to be fixed to the surface cover of the pad. The important feature is that the location of this sensor allows an accurate measurement of the temperature of the interface between the mattress pad and the patient. The interfacial sensor will commonly be located in the area of the heaviest positioning, such as the shoulder area, the buttock area and / or the area of the upper part of the thighs.
In use, at least the temperature sensor fixed to the patient will be fixed to the patient's skin and will make it possible for the patient's body temperature to be monitored. In the context of this invention, the body temperature of the patient comprises a core temperature of the patient, a temperature of the skin of the patient, the temperature of a particular organ or any other temperature that may be important to monitor during surgery.
Naturally, more than one sensor can be used
of temperature in each of the locations, for example two sensors can be fixed to the patient in such a way that the temperature measurement system comprises four temperature sensors. During an invasive procedure, a temperature sensor can be fixed to the patient's skin and another temperature sensor can be fixed to an invasive location.
Due to the variability of a patient's weight on the mattress pad (for example, 5 kg in children-200 kg in adults) it could be difficult to calibrate the "interfacial sensor". Therefore, careful monitoring of the temperature of the heating element and the temperature of the patient is also necessary. However, the "interfacial sensor" is important since, in the case that the sensor fixed to the patient is not
properly positioned and thus not providing accurate temperature feedback, the "interfacial sensor" ensures that the pad is not allowed to reach excessive temperatures that could damage the
i
patient. Therefore, it is clear that each of at least the three temperature sensors of the temperature measurement system of the present invention are important to enable the safe and efficient operation of a hot mattress pad.
Temperature sensors that are suitable for use in the present invention include electrical temperature sensors such as thermocouples, thermistors. or resistance thermometers (also known as Resistive Temperature Detectors or RTDs) which generate electrical signals which are then converted into temperature readings.
It is also possible to measure the temperature i
using non-electrical techniques, for example optical temperature measurement techniques. Non-electrical temperature sensors such as fiber optic sensors can also be used with the present invention.
The fiber optic sensors are capable of measuring the full temperature range that is appropriate for a patient's environment (for example 15 ° C to 50 ° C). Additionally, fiber optic sensors make it possible
an exact measurement of the temperature (for example ± 0.5 ° C) and a defined resolution of the temperature (for example ± 0.1 ° C). Suitable fiber optic sensors include the Fluotemp range of sensors, available from Photon Control Inc.
The fiber optic assemblies can be used to build an individual fiber optic sensor. A set of optical fibers forming an individual sensor is distinguished on multiple sensors each with an individual optical fiber by the manner in which the sensors are connected to the converter module. An individual connection represents an individual sensor, even if multiple signals from the optical fibers are associated before connection with the converter module.
Fiber optic sensors that are suitable for use in the present invention may comprise at least one optical fiber and at least one phosphor material located at a distal end of at least the optical fiber, at least the optical fiber material. phosphorus is characterized in that it emits, when excited, a detectable optical radiation that varies as a known function of the temperature of at least the phosphor material. In use, the temperature measurement system can transmit light, optionally light pulses, from the proximal end of an optical fiber to the distal end
of the optical fiber. The light returning from the distal end of the optical fiber to the proximal end of the optical fiber would include the light emitted by at least the phosphor material. The detection of the emitted light and the comparison against the known variation of the light emitted as a function of the temperature of at least the phosphor material makes it possible for the temperature at the distal end of the optical fiber to be measured.
At least the phosphor material should be selected such that the intensity of a line within the emission spectrum of at least the phosphor material changes through the temperature range of interest. Preferably, these changes occur rapidly, to keep up with any rapid changes in temperature that might occur, and occur with good signal strength, to enable accurate temperature measurement. Therefore, careful selection of at least the phosphor material allows temperature measurements across a temperature range of interest to be made quickly and accurately. For example, an accuracy of ± 0.1 ° C can be achieved in the range of 36 ° C to 41 ° C using a phosphor tip sensor.
At least the optical fiber must be resistant so that it does not twist easily or does not reach
double. This ensures that detectable optical radiation is transmitted to the near end of at least the optical fiber.
i
The radio-translucent optical fiber sensors can be used with the claimed temperature measurement system and a radio-translucent mattress hot pad to ensure that both the patient heating system and the claimed temperature measurement system do not interfere with X-rays. Additionally, the patient's heating system and a temperature measurement system with fiber-optic sensors can be used with a radio-translucent operating table, such as Wilson's radiolucent Wilson Plus frame. " 11. The patient heating systems and the claimed temperature measurement system can also be used with a variety of other operating tables, such as the Jackson table, the Amsco table and the Skytron table.
In one embodiment of the present invention, a combination of electrical temperature sensors and optical temperature sensors can be used. In particular, at least the temperature sensor adapted to be fixed to a patient located on the pad can be an electrical temperature sensor and at least the temperature sensor that is adapted
to be attached to the heating element and at least the temperature sensor which is adapted to be fixed to the pad can be optical temperature sensors. If used with a radio-translucent patient heating system such as LMA PerfecTemp, the ordering of the temperature sensors described above ensures that the hot mattress pad remains radio-translucent.
In embodiments using fiber optic sensors, the converter module may be a three-channel opto-electronic converter module (or any other device capable of converting optical signals, for example, a beam splitter).
At least the converter module can generate an output signal to be transmitted to a control means for regulating the heating of the mattress pad. The control means and at least the converter module can be located within the same housing, or in embodiments comprising more than one converter module, one of the converter modules can be located within the same housing as the control means and one of the converter modules can also be located elsewhere.
Commonly, the mattress pad is heated electrically and the control means regulates the
Heating the mattress pad by adjusting the current flowing through the mattress pad in response to the output signal from at least the converter module. However, an alternative means can be used to heat the mattress pad, for example using a flow of hot water. Optionally, the output signal is digitally transmitted to the control means, either via an electrical cable or wirelessly.
A sensor monitoring means can be used to monitor if one or more of the sensors is disconnected from the converter module. If one or more of the sensors are disconnected from the converter module, the sensor monitoring means can initiate an audible or visible alarm and / or the control means can deactivate the heating element. For example, if the mattress pad is electrically heated and the sensor monitoring means detects that one or more of the sensors have been disconnected from the converter module, the control means can cut the power supply to the heating element.
The system may also comprise a means which is suitable for recording and / or displaying temperature information, which medium may be integrated with the control means or may form a separate device.
The temperature sensors of the present invention may be disposable or reusable or a combination of disposable and reusable temperature sensors may be used. In particular, at least the temperature sensor adapted to be fixed to a
I
The patient that is located on the pad can be disposable since this temperature sensor makes direct contact with a patient while at least the temperature sensor which is adapted to be fixed to the heating element and at least the temperature sensor that is adapted to be fixed to the pad will not make direct contact with a patient.
The use of disposable temperature sensors in medical applications allows new sterile sensors to be used with each patient. In this case, disposable sensors must be economical and must have the ability to be easily connected to and disconnected from the converter module. Alternatively, the reusable temperature sensors can be used in medical applications with the proviso that the temperature sensors are insulated in such a way that there is no need for them to be sterilized or, if they can not be isolated, the reusable temperature sensors. They must be sterilized between each use. In this case, the reusable sensors must be easy to sterilize and
they must have the ability to be easily connected to and disconnected from the converter module.
The temperature sensors may comprise a means for fixing the distal end of the i sensor
temperature in a desired location. The means for fixing the distal end of the temperature sensor may vary depending on the character of the desired location, ie the means for securing the distal end of the temperature sensor to the heating element may differ from the means for fixing the distal end of the sensor. temperature to the pad and may vary from the medium to attach the distal end of the temperature sensor to the patient. However, the means for attaching the distal end of the temperature sensor to a desired location may comprise an adhesive, for example the means for attachment could be an adhesive pad. The adhesive pads can be designed to ensure that the adhesive does not insulate the sensor and distort the sensor signal. Adhesive pads comprising a hypoklergenic adhesive are particularly suitable for medical applications.
The temperature sensors of the present invention are designed primarily for non-invasive use, however, the skilled person could easily devise a means to fix the distal end of the sensor
of temperature in an invasive location. For example, an invasive sterile probe could function as a channel to insert and fix the distal end of the i-sensor.
temperature in an invasive location. Any isolation effect associated with the invasive sterile probe could be calculated and compensated to ensure an accurate temperature reading at the invasive location. The use of the i
The measurement of the temperature in an invasive location could make it possible for a patient's core temperature to be monitored better.
