Description

EQUIPMENT FOR USE IN PERFORMANCE OF HEART MASSAGE

The prior art

BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a cardiac massage device for placement above the sternum of a person with cardiac arrest, as the backbone of a helper performing cardiac massage, cardiopulmonary resuscitation (CPR).

Preparedness assistance in the event of cardiac arrest includes cardiac starters, which are an electrical defibrillation through which power surges of up to 2000 V can be delivered through the cardiac chambers to initiate these.

The use of this equipment naturally presupposes the presence of the patient, which is rarely the case.

In addition, the use of artificial ventilation by mouth for the nasal method is known in combination with heart massage.

However, performing cardiac massage is not easy to perform as it requires both knowledge of the location of the pressure, namely over the lower part of the sternum, and partly an appropriate compressive force, to ensure a squeeze of the chest of 4-6 cm. Furthermore, the number of pressures per the pressure rate should be about 100-120 pressures per minute. minute.

Failure to observe these parameters will not produce the desired effect, namely cardiac onset. In addition, there is a risk of fracture of the ribs by incorrect or excessive pressure.

Equipment for training people in this type of cardiac arrest is known, consisting of a chest chamber portion with auditory and visual marking of both thrust and pressure. However, this is only equipment for use in the training of assistants, and not equipment for use in the event of a cardiac arrest.

From US 6,427, 685 B1, an apparatus comprising a flexible disc is known which can be formed according to the patient's sternum and the practitioner's wrist. This disc, however, is not shaped hereafter, but based solely on adaptation to the shape of the sternum and the hand root, respectively, when the user exerts compressive force on the disc.

The object of the invention

The object of the invention is to improve the effect of cardiac massage, thus ensuring the greatest possible effect thereof, while significantly reducing the risk of injury to the patient and the psychological burden of the helper.

This is achieved according to the invention by the use of a heart massage device for placement over the sternum of a person with cardiac arrest, as a support for the hand root of a helper performing cardiac massage (CPR), which comprises a plate formed on the upper side according to the shape of the hand root, and on underside according to the shape of the chest.

In this way, it is ensured, firstly, that the equipment is placed in the correct location above the sternum, as the underside of the plate corresponds to the anatomy, and secondly that the helper's root is placed, namely, over the lower part of the sternum, the equipment upper side being shaped as a seat for the sternum.

By making the plate of a resilient material as defined in claim 2, it is ensured that the pressure is appropriately distributed over the chest so that damage to the ribs is avoided.

As provided in claim 3, providing the equipment with embedded pressure sensors for controlling the root canal pressure, and by means of auditory or visual marking thereof, the optimum effect can be assured, since it is possible to detect whether the pressure is the desired and thus a depression of the pressure. sternum of between 4 and 6 cm.

By incorporating buzzers in the equipment as claimed in claim 4, the helper will be able to hear the pressure frequency and thus exert the pressure influence at the correct frequency of between 100 and 120 pressures per minute. minute.

As provided in claim 5, providing the equipment with a strap extending over the helper's hand ensures that the hand is held to the equipment during use.

By, as defined in claim 6, embossing the top surface of the plate with a hand / finger imprint, the correct placement thereof on the plate is ensured.

Finally, as claimed in claim 7, it is appropriate to round the edges of the plate so that skin abrasions are avoided.

The drawing

An exemplary embodiment of the invention will be described in more detail below with reference to the drawing, in which: - Fig. 1 shows the equipment from above; Fig. 3 shows the equipment in perspective, Fig. 3 shows the equipment in perspective and Fig. 4 shows a sectional view of a chest with the equipment in use for heart massage.

Description of an embodiment

An example of a device according to the invention is shown in FIG. 1-3.

It is designed as a substantially square plate, which is corrugated to form a seat partly for the sternum of a patient and partly for the hand root of a helper's hand.

This is evident from the drawing, in which the equipment is shown as a square plate 1 with a curved leading edge 4 and a rear edge 3 for forming a finger grip for the fingers 7 of an auxiliary hand 5, as shown in FIG. 4th

Furthermore, a seat 3 is formed for the hand root 6 on the upper side of the rear part of the plate. To facilitate the positioning of the hand on the plate 1, an imprint of the hand / fingers may be marked as marking.

The plate 1 is preferably made of a resilient material such as rubber or similar material. Its width is between 10 and 14 cm in both width and length.

The purpose of the flexible plate 1 is to ensure an appropriate distribution of the root canal pressure against the patient's chest, thus ensuring that no damage to the patient's ribs occurs.

Sensors and transducers are embedded as indicated by dashed line 2 in FIG. 1-3.

These sensors must sense the pressure and signal LED 9 mounted on the top of plate 1.

Furthermore, there may be embedded sounders for auditory signaling of the pressure frequency.

These records are intended to control the performing massage, as well as help to soothe the helper in the indicative marking of both the correct pressure and thus the squeezing of the chest as well as the pressure frequency being the correct one.

The plate 1 may be provided with a hand strap 10 which extends over its upper side and which ensures that the hand 5 is properly placed on the equipment, as well as helping to hold the hand and equipment together during use.

The use of the equipment for heart massage will then be described.

The heart massage should usually be combined with an artificial ventilation in the form of the mouth-nose method. In practice, this means that once every four times a heart massage, ventilation must be given once. The heart massage, which is a depression of the sternum of between 4 and 6 cm, which is shown by the arrow 8 in fig. 4 shall be done at a rate and a pressure frequency of between 100 and 120 depressions per minute.

To compress the sternum in the desired 5 cm, a pressure of about 40 to 45 kg must be pressed. However, this pressure will depend on the patient's size, age and gender.

By appropriate calibration of the sensors 2 embedded in the plate 1, from the diodes 9 mounted on the upper side of the equipment, the signals needed by the helper to ensure the correct compressive power and frequency can be output.

Refer to Fig. 4 for the exercise of the heart massage itself.

The equipment 1 is placed over the sternum of the patient, with the helper's hand in grip around the plate 1 with fingers 7 in grip around the leading edge of the plate.

4. In this position, the hand root 6 is placed in the correct position on the plate and over the sternum so that the depression 8 of the sternum can begin. The sensors 2 in the plate 1 signal the force of the delivered pressure and this is displayed on the diodes 9 and possibly via a sound sensor not shown in the plate.

For every four pressures, a signal is stopped to stop the heart massage and the start of artificial ventilation, after which the heart massage can be resumed.

As the plate 1 is suitably flexible, the pressure will be appropriately distributed over the sternum, thereby preventing pressure damage.

The complete control of performing the massage helps to achieve the best possible result, as well as soothing the helper.

The equipment can easily be stored in an emergency aid box, thus being a natural part of its contents. It is easy to use and also relatively inexpensive to produce as no expensive components are included in the equipment.
