Abstract

Two simple, inexpensive to produce, with new, low-inertia controllable heating and humidifying elements, working with high electrical efficiency devices for heating and humidifying respiratory gases according to the Verdunster-, evaporator principle will be described with reference to two embodiments. The first device example is very small, compact, lightweight, working largely independently of position and is intended primarily for mobile use. The second device example is bottle-shaped, lightweight, largely independent of position, working without external pump and humidification water reservoir, is optimized especially for use in home care. These respiratory gas warm-up wetting devices are controlled by an electrical-electronic control power supply and monitoring device, according to the prior art.

Description

  • The dry and cold inhaled air physiologically reaches optimally tempered via the nasal mucous membranes and the nasopharynx and moisten the trachea, the bronchi and finally the gas exchange the alveoli. However, only an undisturbed filtering and cleaning function of the bronchial mucous membrane allows the elimination of mucus and foreign bodies, but this is only possible with an optimal conditioning of the inhaled air with heat and humidity. Physiologically, this is achieved by a stronger or weaker perfusion of the nasal mucosa with a resulting change in the delivery of moisture and heat to the respiratory air. In artificial respiration and respiratory aid therapy, however, these physiological functions must be replaced.
  • Commercially available active air heating / humidifying devices use the principle of breathing air over the surface of heated water or over heated surfaces that evaporate the water to evaporate to condition it with heat and moisture. These surfaces are often artificially enhanced by the additional use of float paper parts immersed in the water. This can achieve an increase in effectiveness. To be mentioned, for the sake of completeness also today rarely used methods such. As the conditioning of the respiratory gases by hot water flowed porous hollow fibers or the portioned dispensing hot steam.
  • A special position still take devices that extract moisture and heat as a heat-moisture exchanger of the exhaled air of the patient and then each of the dry inhaled air, but with certain losses, again. However, these exchangers have limited applicability only to special cases of artificial respiration and spontaneous breathing.
  • Problems with respiratory gas warm-up wetting devices
    • 1. The generation of optimally tempered and humidified respiratory gases at different Atemgasfluß or respiratory minute volumes such. As in artificial respiration of infants, children, adults and respiratory aid such as mask ventilation, CPAP therapy u. a ..
    • 2. Rapid operational readiness with avoidance of a "hot shot" (suddenly hot breathing gases) z. B. at the beginning of an artificial ventilation therapy. This danger threatens especially in humidifying-warming devices that require larger amounts of water for their function. They require this preheating to immediately receive sufficiently conditioned respiratory gases in emergency ventilation cases.
    • 3. Rain water by cooling the respiratory gases in the long breathing tubes with the need for water traps or expensive elaborately electrically heated sterilizable breathing tubes.
    • 4. Bacteriological-hygienic problems with breathing gas leading directly to the patient applied parts. Necessity of using sterile, mostly expensive disposables or laborious cleaning, disinfection and steam sterilization of the multiple items (tubing, connectors, heating-moistening devices).
    • 5. Simple and safe use in the patient in everyday routine with economically justifiable strains on the budget and the environment.
  • With the invention described below, the new device for heating and humidifying respiratory gases, the problems mentioned are largely solved.
  • Two exemplary embodiments for the multiple use, especially in the field of home care, are described below with reference to 1 - 7 described.
  • 1 shows the heart of the device of 2 , the heated humidifier wrap for the respiratory gases. It consists of a corrugated, thin metal heating tape 1 (preferably stainless steel), with a strip of blotting paper on top 2 , This heating tape 1 is with his beginning 4 on the winding body 5 with the central electrical, tubular contact 6 connected. The free end 7 of the heating tape 1 is with the electrical connector 36 (S. 2 u. 3 ). heating tape 1 and paper strips 2 curled up to form the wrap 3 with its multiple air channels and thus large surface, for the cold and dry, flowing air. Wrappings of similar type, but impregnated with hygroscopic chemicals, are used as known in today's HMEs (heat and moisture exchanger). The crucial peculiarity of the invention, however, is that smooth paper-sheet stiffeners in close connection with an electrically heated, corrugated heating tape, rolled up as a roll 3 , to be used.
  • Device description of the first embodiment
  • 2 shows in perspective and transparent drawn the device for heating and humidifying respiratory gases separated in upper part 8th and lower part 9 , The upper part has a breathing gas outlet 10 on which the breathing gas temperature sensor piece 11 is attached, that for connecting a patient with a connecting piece 12 provided with a connection cable for the electrical electronic control power supply device.
  • Through the curved surface 13 of the top 8th you can see the upper moistening warm-up wrap drawn in dashed lines 14 and in the center of which is formed as a tube electrical contact 15 , At the circumference of the upper part 8th is the electrical contact plug 16 that with the end 7 the winding heating tape is connected, attached. The lower part 9 has the gas inlet 17 on and at its arched base 18 the water outlet 19 , as well as the electrical connector at his circumference 20 , Additionally you can see in the lower part 9 the lower warm-up moisten wrap 21 with its central, electrical contact tube 22 into which the electrical connector 23 is introduced. The between top 8th and lower part 9 arranged flat-cylindrical central part 24 has at its top a tightly welded, fine-meshed net (sieve) 25 on as well as a fine-meshed net (sieve) 26 at its bottom. These sieves (nets) 25 and 26 form together with the cylinder wall of the middle part 24 a chamber through which the water supply pipe 27 the inflowing dampening water evenly on the upper roll 14 and lower wrap 21 is distributed in flowing through the breathing gas.
  • 3 shows in section, section plane I ... I, 2 The Breathing Gas Warm-Up Moisturizer Device. Her domed shell 13 shows the gas outlet 10 with the attached breathing gas temperature sensor piece with connection cable 11 and patient connector 12 , In the cylindrically shaped part of the upper part 8th you see the wrap 14 with the electrical contact tube 15 and the electrical contact plug 16 connect electrically. The lower part 9 shows the gas inlet 17 and at the arched ground 18 (with support rib for the wrap) and the water outlet 19 , In the cylindrical part of lower part 9 there is the lower winding 21 , with its central, electrical contact tube 22 is electrically connected, as well as with the contact plug 20 , The middle part 24 has in the upper part a close-meshed net (sieve) 25 on as well a net (sieve) 26 in the lower part. The nets are each shown dotted. The nets 25 u. 26 form with the cylindrical wall of the center piece 24 a closed humidification chamber, which is central to the electrical contact pin 23 is traversed and in the water supply pipe 27 opens. This pin connects, as indicated by dashed lines, in the assembled state, electrically the upper and lower Anwärm-moistening-winding the Atemgas-Anwärm-moistening device.
  • Device function of the first embodiment
  • The dry, cold breathing gas flows over the inlet port 17 the warm-up wetting device over the base 9 , through the numerous air channels of the heated warm-up wipe wrap 21 , the pressed on, distributor humidification chamber 24 with their welded-on nets (sieves) 25 u. 26 in the pressed-up top 8th with the heated warm-up wipe wrap 14 with its numerous air ducts, over the domed lid 13 to the outlet 10 and the attached temperature sensor piece 11 with the connecting piece 12 and via a short breathing gas connection tube with adapter (not shown), well-tempered and moistened, via a tracheal tube, a tracheal cannula or breathing mask to the patient. Is the temperature sensor piece 11 not on the neck 10 plugged, then the electronic control power supply unit prevents commissioning of the moistening-warming device. Decisive for the outstanding function of this respiratory gas-moistening-warming device, however, are their moistening-warming wraps. Their heating elements have a very low heat storage capacity and thus thermal inertia. This results in the possibility of a very rapid electrical change in the heat dissipation performance and additionally in a large control range, which means that z. B. when changing the breathing gas flow and the breathing gas temperature can be kept largely constant within narrow limits.
  • Technically constructive this is achieved by the use of a thin metal strip as a direct, electrically heated heating element. This element is integrated into the wetting-warming coil of the Warm-Up Moisturizer (see p. 1 ). The moistening elements applied to the corrugated metal heating tape also have a low heat storage capacity and thus thermal inertia, since their water absorption capacity is only small (a few milliliters). These moistening elements are formed of blotting paper in strip form and to a winding (s. 1 ) rolled up. This results in a large surface area for the evaporation of water evaporation and intimate contact with the respiratory air, which flows through the multiple air channels formed in the winding. The water supply and distribution for moistening the moistening wraps via the pressed nets (sieves) of the water distributor moistening chamber. An external simple dosing pump, preferably peristaltic pump, controlled by the electronic control power supply device provides for a dosed sterile water supply depending on the preselected respiratory gas flow or respiratory minute volume. The Anwärm-moistening wraps described in their function thus allow even quickly detected by the temperature measuring unit even low respiratory gas temperature changes by means of the electronic control and power supply device via the electrical power supply to the heating element to correct. Unpleasant warm or even dangerous hot respiratory gases z. As a "hot shot" can be avoided with changes in the respiratory gas or respiratory minute volume. Likewise, a so-called "preheating" the Atemgas-Anwärm-moistening device with the danger of sudden hot gases of gases has become unnecessary by the possible fast but sensitive heating of Anwärm-moistening wraps such. B. in the emergency emergency ventilation of a patient required. Due to the compact design and especially the sensitive, fast breathing gas temperature regulation, a patient-near arrangement of the device is possible and thus only a short breathing gas hose as a link to the patient, which causes only a very small drop in temperature of the breathing gases with correspondingly very low condensation water loss. This eliminates electrically heated breathing gas hoses and usually water traps.
  • Device description of the second embodiment
  • 4 shows the 2nd example of the breathing gas warm-up moistening device perspective, transparent and partially drawn schematically. The housing of the device consists of two halves, a bottle-shaped cylindrical upper part 28 with domed lid 29 , Gas outlet 30 with screwed on sensor piece 31 with patient connector 32 , Sensor socket 33 and sensor connection cable 34 and the lower part of the inserted and welded floor 35 , with the electrical connector 36 , the breathing gas inlet nozzle 37 with breathing gas distributor 38 and the dampening water supply nozzle 39 , Through the transparent top part you can see the thin, meandering heating plate 40 with its gaps 41 to a cylinder jacket formed by two (at the top and bottom) connected to it and bent into a circle and welded plastic bands 42 u. 43 , By the on these bands 42 u. 43 attached spacers 44 u. 45 , arises between the Heizblechzylinder 40 and the cylindrical wall of the shell 28 inside adjoining blotting paper cylinder 46 , a wide gap 48 (S. 5 ).
  • 5 shows in section, section plane II ... II 4 , You can clearly see the wall of the upper part on average 28 and this inside tightly fitting the outer blotter paper cylinder 46 and underneath the outer gap 48 that by spacers ( 44 . 45 on the tapes 42 . 43 , s. 4 ) is formed. This gap space 48 is limited by the heating meander cylinder 40 with its gaps 49 and the underlying inner blotter paper cylinder 47 with circulation openings at its lower end (not shown) for moistening water and respiratory gas. Further inward follow the wide inner gap space 50 , in the respiratory gas distributor 38 with its outlet openings 51 , protrudes.
  • 6 shows in perspective, the lower part, the bottom plate 35 with the electrical connector 36 (includes the connections 52 u. 53 for the heating-meander cylinder), the breathing gas inlet nozzle 37 and the dampening water supply nozzle 39 ,
  • 7 shows perspective, schematic and simplified the simple realization of the described meander heating cylinder. On the 2 temperature-resistant plastic tapes 42 u. 43 is the heating meander stamped from a thin, stainless steel sheet 40 put on and at the marked attachment points 54 firmly connected to these bands (eg with rivets, brackets). For very thin sheet metal thickness, the edges of the meanders ( 55 ) especially in the interstices 41 folded or folded at right angles (marked as double line).
  • To produce the heating-meandering cylinder, the two plastic strips with the heating meander fixed thereon are each bent into a circle and their ends are connected by welding. The welded plastic band 43 represents the lower edge of the heating cylinder, on which the electrical power is supplied via the beginning 56 and the end 57 the Heizmäanderblechs. The welded band 42 forms the upper edge of this heating cylinder.
  • Device function of the second embodiment
  • 4 . 5 u. 6 show the Atemgas-warming-moistening device both perspective, transparent drawn as well as in section. Cold breathing gas flows through the gas inlet 37 to the gas distributor 38 with baffle plate and outlet openings and from there, both over the inner surface of the electrically heated heating meander cylinder jacket 40 the one with the close-fitting inner blotting paper cylinder 47 (not drawn) is covered, as well as over the outer surface of the heating meander cylinder 40 through a gap 48 outward through the outer blotting paper cylinder 46 (the top part 28 the device is tight) is formed. If the warm-up wetting device is as in 4 drawn, operated in a vertical position, then these paper cylinders are with their lower ends in the germ-free dampening water, which over the neck 39 supplied from an external reservoir, the bottom 35 The respiratory gas warm-up moistening device covers. However, this Anwärm-moistening device can be exactly as inclined in horizontal or inclined by 45 degrees to both sides. In this case, the side surfaces of the paper cylinders are dipped strip-shaped into the dampening water. This water rises in the flow paper up, moisturizes this completely and is then through the thin-walled heating meander cylinder 40 Warmed up inside and outside heat and evaporated or evaporated. The breathing gas passing over these large surfaces is optimally warmed and moistened and leaves the device via the gas outlet nozzle 30 with screwed on temperature sensor piece 31 with patient connector 32 , The measured breathing gas temperature controls, via the electronic control power supply and monitoring device, the power supply to the heating element of the respiratory gas warm-up moistening device. An over-temperature control of the heating element is detected, via an electronically registered decrease in the heating current with increasing temperature of the heating element and leads to the exceeding of the permissible limit for switching off the heating current and triggering a warning signal. About the electrical connector 36 the power supply takes place. Due to the low heat storage capacity of the thin-walled, metal, heating meander cylinder shell which dips only a very small part in the Anfeuchtwasserreservoir, as an electric heating element in combination with the thin paper cylinders, as humidification with low water storage capacity, in turn, the cheap, fast Low-inertia air temperature and humidity control with the help of the connected control power supply device.
