Fundamental Problem of the Invention

The purpose of the invention is to provide an improved device for medical assistance to a patient in an emergency.

Solution According to the Invention

To meet the objective, the invention teaches a device for the medical assistance of a patient in an emergency, according to claim 1. As the device comprises a defibrillator, as an additional therapeutic device, defibrillation can also be performed, in addition to cardiac compression, in order to allow an effective treatment of the patient in an emergency.

In order to meet the objective, the invention further teaches a device for medical assistance to a patient in an emergency, according to claim 3. As the therapeutic device comprises a respiratory therapeutic device, in an emergency it can be performed by means of the invention to gain access to the patient's respiratory system, in particular, to carry out life-saving measures.

The invention can be used, in particular, in patients who are at an increased risk, due to existing circulatory heart disease, of experiencing sudden cardiac arrest or cardiac movements that do not produce cardiac output (e.g., palpitations) or respiratory arrest. In particular, the emergency may be a cardiac arrest or respiratory arrest. By means of the invention, one can reduce the probability that a patient will die as a result of the emergency.

As monitoring and therapeutic devices are placed on the item of clothing, it is possible to provide a device that can be worn on the body. In particular, this can contribute to increasing patient mobility and improving patient's quality of life. Through the invention, the monitoring and treatment of the patient takes place without the active involvement of the patient or third parties. As the monitoring device and therapeutic devices are operatively connected, the monitoring device, when it determines an emergency, can trigger a treatment or different treatments in a logical medical sequence or, simultaneously, as a result, of the therapeutic devices .

Structure and development of the solution, according to the invention

Advantageous modalities and developments that can be used individually or in combination with each other form the subject of the dependent claims.

The device according to the invention preferably comprises a defibrillator as a therapeutic device. Preferably, the defibrillator is disposed on the clothing item. The preferred defibrillator can perform cardioversion and / or defibrillation. It preferably comprises at least two electrodes, which can be connected to the patient, preferably on the patient's chest wall, in order to provide the patient with a current pulse sufficient for defibrillation. The electrodes are preferably gel release electrodes that, before applying the current impulse, release a conductive gel between the electrode and the chest wall or allow the skin to be protected in a different way.

A preferred defibrillator is operatively connected to the monitoring unit. Preferably, the defibrillator performs defibrillation or cardioversion when the monitoring device detects cardiac arrest, at certain intervals and with increasing intensity, until the monitoring device detects a restoration of cardiac activity or until the defibrillator is externally disabled, for example, by a paramedic from a rescue service.

Preferably, the device according to the invention comprises as a therapeutic device a cardiac compression device for cardiac resuscitation. With this embodiment of the invention, a minimum circulation can be obtained that is again produced and / or maintained in patients. Preferably, the monitoring device can trigger cardiac compression when it determines a cardiac arrest and, in particular, it can be performed, preferably, for a sufficient period of time until it detects the restoration of cardiac activity or until the cardiac compression device is externally disabled, for example, by a paramedic from a rescue service.

The cardiac compression device is preferably controlled so that a resting phase follows, respectively, numerous predetermined cardiac compressions, in which other therapeutic measures can be performed, preferably, through one or more therapeutic devices different from the device ( for example, artificial respiration, intraosseous drug distribution). The cardiac compression device is preferably controlled, so that when the patient is also treated with the defibrillator, cardiac compressions occur, respectively, between individual defibrillations and / or cardioversions. The preferred frequency of cardiac compressions is between 30 and 200, preferably between 50 and 120 compressions per minute. The residence time in the maximum compressed position is preferably the same as in the relaxed position, i.e., the pressure phase and the relaxed phase have the same length. A preferred cardiac compression device uses air bags that are preferably inflated and deflated by a pump, for example, as described in EP 1 550 398 A1. The relevant contents of the document mentioned above form part of the present description. Preferably, the cardiac compression device presses the sternum bone in the transition region from its center to the lower third against a spine, preferably by 2 to 12 cm, in particular, preferably by approximately 6 centimeters. The preferred compression rate is approximately 50 to 70, in particular, preferably approximately 60 compressions per minute. A preferred cardiac compression device, for this purpose, is provided with a pneumatic plunger or spring mechanism. The support surface of the plunger is preferably between 2 and 10, in particular, preferably, approximately 5 centimeters wide and 5 to 20, in particular, preferably approximately 10 centimeters long. In order to allow sufficient pressure against the spine, the garment adopts a rigid state in the posterior region, at least for the duration of the cardiac compression.

An additional preferred cardiac compression device operates according to the chest pump method. Preferably, it comprises a substantially tubular air bag, for example, similar to an oversized blood pressure glove, which is placed around the chest and is inflated and deflated by means of a pneumatic device. With this embodiment of the invention, a substantially uniform compression of the entire chest and, thus, a genuine reduction of the chest cross section and, in particular, also the chest volume can be obtained. The preferred inflation pressure is between 150 and 350, in particular, preferably, approximately 250 millimeters of mercury. The preferred compression rate is approximately 50 to 70, in particular, preferably approximately 60 compressions per minute. An achievable advantage of this embodiment of the invention is that through compression of the chest, a compression of the lungs can also be performed. This can also contribute to the fact that, in addition to minimal circulation, minimal breathing is also maintained.

A preferred cardiac compression device operates according to the principle of interposed abdominal counterpulsation (IAC - CPR). In this case, during relaxation of the chest, the abdomen is compressed in the navel region, for example, by means of a plunger or by means of a substantially tubular air bag, as described above in connection with the chest pump method. The abdominal compression pressure is preferably between 50 and 150 millimeters of mercury. Preferably, compression occurs according to the principle of interposed abdominal counterpulsation (IAC - CPR) with intubated patients. In addition, the device according to the invention preferably comprises a suitable respiratory therapeutic device, as described below. In a preferred modification of the interposed abdominal counterpulsation, continuous compression of the abdomen occurs, that is, also exercised during chest compression, also denoted as abdominal ligation.

In a preferred embodiment, the cardiac compression device comprises means for elevating the chest during the relaxed phase. Such a cardiac compression device can operate according to the active compression-decompression method (ACD-CPR). In this embodiment of the invention, an intrathoracic vacuum is produced in order to improve the diastolic venous return. This can increase both the intrathoracic blood volume and improve lung ventilation. Particularly preferable, the cardiac compression device combines active compression compression with interposed abdominal counterpulsation. For this purpose, it can be understood, for example, two pistons, respectively, one of which is capable of being connected to the chest and the other to the abdomen, and which are preferably connected to each other through a lever. Then, alternatively, like two * weighing scales, the chest is compressed and the abdomen is decompressed (systole) or vice versa.

In a preferred modification of the aforementioned method for cardiac compression, a higher compression rate is used, preferably between 100 and 200, preferably, particularly between 120 and 150 compressions per minute.

In a preferred embodiment of the invention, it is assumed that as soon as the detection of the device determines the respiratory arrest, after a certain latency period, the trachea is perforated by means of the perforation unit below the larynx and an artificial respiration tube is pressed endotracheally through the cannula lumen towards the lungs. The artificial respiration tube is preferably only slightly smaller in diameter than the cannula. It is pressed towards the lungs, preferably between 5 and 15 centimeters, in particular, preferably approximately 10 centimeters. Preferably in the upper third of the tube a cuff is provided. When filling the cuff with oxygen, the wall of the trachea is sealed. As a result, aspiration of foreign bodies, for example, vomiting, can be prevented.

Preferably, the respiratory therapeutic device comprises at least one reservoir with at least one drug or is connected to such a reservoir in order to deliver the drug from the reservoir to the patient's respiratory system. Preferably, the respiratory therapeutic device can provide, in particular, a plurality of drugs and, for this purpose, comprise one or more drug reservoirs and / or be connected to it, as, for example, in US 5,405,362, all relevant contents of the same form part of this description referring to them.

Brief Description of Drawings

The invention will be described in more detail later in this document with reference to drawings and schematic modalities with additional details, in which:

Figure 1 shows a schematic block diagram of a device, according to the invention, for the medical assistance of a patient in an emergency;

Figure 2 shows a schematic view of a drilling unit for the trachea.

Description with reference to the modalities

A device for medical assistance to a patient in an emergency, according to the present invention, is schematically shown in Figure 1. Device 1 comprises a shirt 2 that fits firmly on the body of its user. In shirt 2 in the transition region from the central part to the lower third of the user's sternum bone, a tubular air bag 3 from a cardiac compression device 4 is sewn into shirt 2, in order to perform cardiac compression in an emergency , according to the chest pump method to maintain minimal circulation. The air pocket 3 can be inflated and deflated by means of a pump, such as, for example, that described in EP 1 550 398 A1. In a further embodiment of the invention, through a pneumatic plunger or spring mechanism with a support surface of approximately 5 x 10 cm along the sternum bone, the sternum bone is pressed in the transition region from the central part to the third lower at a frequency of approximately 100 for approximately 6 cm per minute against the spine. The residence time in the maximum compressed position, therefore, is the same as that of the relaxed position, so that the compression and relaxed phases have the same duration. In order to allow pressure against the spine, the harness and / or shirt must adopt a rigid state in the posterior region for the respective duration of the cardiac compression, for example, by means of air bags arranged at this point. In addition, through this unit, access can be created to the bone marrow of the sternum through a perforation cannula for the administration of injectable or infusible drugs.

In addition, two electrodes 5, 6 of a defibrillator 7 are sewn into the jacket 2 which, if required, release gel or allow the skin to be protected in another way and can then perform a cardioversion. In addition, an expansion sensor 8 of a monitoring device 9 is fitted to the jacket in order to monitor the user's respiratory activity.

The piercing device 10a, 10b is provided on the upper part of the jacket 2 by a respiratory therapeutic device 11 which can pierce the patient's trachea 18 with a semicircular cannula 17 of approximately 14 mm in diameter, as a drilling unit. For this purpose, pneumatic means or a pre-tensioned spring are provided, similar to the autoinjector described in US 5,405,362. An oxygen unit 12 of the respiratory therapeutic unit uses a sealed reservoir 19 in which medical oxygen is stored. The reservoir is accommodated in the drilling device 10a, 10b or an oxygen unit 12 of the central control unit. As soon as the monitoring device 9 detects a respiratory arrest, after a certain latency time, the user's trachea is punctured below the larynx through the semicircular cannula 17, through the puncture device that is pneumatically moved by force spring in the direction of arrow 20 from position 10a to position 10b.

Subsequently, an artificial respiration tube 21 that is only slightly smaller in diameter than the perforation cannula is pressed through a spring 23 and a plunger 24 through the cannum lumen approximately 10 cm endotracheally towards the lungs. After the tube has been fully pressed forward, a cuff is filled with oxygen in order to seal the tube 21 from the wall of the trachea and, thus, avoid aspiration, for example, of vomiting. From the oxygen reservoir 19, as indicated by the arrow 22, approximately 8 liters of medical oxygen per minute are inflated in order to supply with oxygen the minimum passive respiratory movements that occur during cardiac compression. In the stages of compression rest, the oxygen and / or gas mixture containing oxygen is inflated by means of a pump, not shown, at a predetermined frequency in the form of individual artificial breathing movements.

A medical device 13 uses a sealed reservoir, in which different emergency drugs (e.g., adrenaline) are present, separated from each other in the solution. Through a thin catheter, which in an emergency is automatically pressed through the lumen of the endotracheal tube 21, approximately 20 cm into the trachea, drugs can be automatically administered deep into the trachea, in order to optimize mechanical resuscitation attempts. unique. Aspirated material can also be sucked through the catheter using a pump, as a vacuum source and collected in a sealed container.

The oxygen and drug reservoirs, pumps and control and evaluation devices, as well as a power device 14, a GSM transmitter and receiver 10, a steering location device and a GPS 15 positioning device are combined in one control unit central 16, which is also sewn into the jacket 2. By means of conductors and tubes sewn into the jacket 2, the central control unit 16 is connected to the other device components mentioned above.

The features described in the description mentioned above, the claims and drawings can be important, both individually and also in any combination for the development of the invention in its different modalities.
