Definitions
- the invention relates to a device for testing anesthetic and respiratory devices, with a lung bag arranged between two relatively movable flaps, with a lung inlet and adjusting means for adjusting the simulation parameters.
- lung simulators are used to check that respiration equipment of all kinds as well as anesthesia devices function properly before being used on humans.
- the test lung should be able to simulate different lung types if possible.
- the characteristics of a lung are determined by the parameters Resistance (Respiratory Resistance), Compliance (Lung Hardness) and Leakage.
- Cost-effective conventional test lungs are usually formed by a simple rubber pouch (or balloon), which has exactly one resistance (respiratory tract resistance), one compliance (lung hardness) and no leakage.
- test lungs are known, which for example work by means of a bellows or a cylinder-piston system.
- the adjustment of the resistance ie, the airway resistance level
- the adjustment of compliance ie, lung hardness
- test lungs are very heavy, complicated to operate, expensive and usually only to be operated by means of external energy.
- the invention is therefore based on the object to provide a simple inexpensive producible test lung, which avoids the disadvantages mentioned.
- this is achieved in that at least one of the two flaps is formed as a resiliently deformable flap.
- Auslizingung is that both flaps are designed as elastically deformable lobes.
- the lung bag is thus arranged symmetrically between the two deformable lobes. This allows for uniform expansion and contraction of the lung pouch.
- the flaps are advantageously firmly clamped at one end and spring elastically deformable.
- the flaps thus act on the nature of leaf springs. Direct selection of the width and material thickness can influence the spring properties.
- At least one of the lobes consists of plastic.
- Plastic flaps are chemically very resistant, body-friendly and durable.
- the lobes advantageously consist of an armored fiber composite.
- the reinforcement may, for example, consist of glass fibers or polycarbonates.
- at least one of the lobes consists of spring steel. Spring steel allows a low wall thickness of the lobes and thus a very compact design.
- the two lobes are integrally connected.
- the two tabs may preferably be connected to one another in a U-shaped manner.
- the resilient length of the lobes is expediently adjustable by means of auxiliary means.
- the spring hard eder lobe and on the other hand, the usable volume of the lung bag can be changed.
- the aids are advantageous in that the free ends of the lobes are formed with one another and slide in the longitudinal direction of the lobes.
- the slider can grasp the lobes from the outside or enforce them.
- the locking of the slide can be done, for example, by means of a releasable clamping screw.
- the slide is expediently latched stepwise. This makes it possible to obtain clearly defined and repeatable test parameters. In addition, this also prevents the parameters from being inadvertently displaced during the test.
- the lung bag is advantageously flat and replaceable. Due to the flat design, the lung bag ideally adapts to the gap between the two flaps. The flat shape also allows a relatively large sizing volume. The exchangeability of the lung bag makes it possible to test requirements with different lung volumes with the same test lung.
- the lung parameters "resistance” and / or “compliance” (lung hardness) and / or “leakage” (leakage) are expediently adjustable independently of one another in different stages Resistance, adjustable lung hardness and adjustable leakage at different levels, virtually all lung types from babies to adults can be simulated without the use of additional adapters.
- a stepless leakage simulation is provided.
- the function of the patient flow triggering which is very delicate in practice, and ventilation with leakage can be checked in a simple manner.
- the flow, pressure and / or volume measurements are integrated in the device and that the values can be displayed on the test lung by means of a display unit.
- 1 is a plan view of a test lung
- Fig. 2 is a view of the test lung shown in Fig. 1, in the direction of
- FIG. 3 shows a cross section through the test lung shown in FIG. 2, along the
- FIG. 4 shows a perspective view of the test lung shown in FIGS. 1 and 2.
- the test lung shown in FIGS. 1 to 4 has an inlet stub which is rotatably connected to a housing 2 about its longitudinal axis.
- the inlet nozzle is provided with at least one channel 1a, which can be brought into coincidence with through openings 2a in the housing 2.
- the inlet nozzle 1 can be fixed in a desired rotational position by means of a detent 3 designed, for example, as a ball catch or as a clamping screw. As a result, a desired passage cross section can be set.
- a connecting piece 4 On the opposite side of the inlet nozzle 1 is a connecting piece 4.
- a balloon-like, replaceable lung bag 5 can be connected to the connecting piece.
- the lung bag 5 is arranged between two elastically formed lobes 6, 7.
- the two tabs 6, 7 are preferably connected in one piece and U-shaped around the housing 2 with each other. To inflate the lung bag 5, the lobes 6, 7 be spread apart. Due to their resilient properties, the lugs 6, 7 oppose the spreading to a certain defined resistance.
- a regulating valve 8 is arranged laterally on the housing 2.
- the regulating valve 8 serves to set a simulated loss of leakage. In the position shown in FIG. 3, the regulating valve 8 is completely closed and the leakage loss is therefore equal to zero. By unscrewing the regulating valve 8, the leakage loss can be adjusted stu ⁇ fenlos.
- a scale 9 is attached at the front side of the housing 2. With the help of this scale 9 can be determined in which rotational position, the inlet port 1 is currently. On the basis of the scale, the simulation parameters can be changed stepwise or continuously. The set values can be reproduced at any time.
- the free ends of the tabs 6, 7 are connected via an adjustable slide 10 mitein ⁇ other.
- the slider 10 By moving the slider 10, the spring properties of the tabs 6, 7 and thus the so-called compliance, ie the lung hardness of the test lung, can be adjusted.
- the slider 10 is by means of latching openings 11 in the lobes 6, 7 engaging Vorsprü or cam gradually detected. By shortening the free length of the tabs 6, 7, the spring stiffness thereof is heard. At the same time, the usable volume of the lung bag 5 is reduced.
- a locking screw 12 angeord ⁇ net which is used for attachment of the connecting piece 4 opposite end of the lung bag 5 to the lobes 6, 7.
