JP7795198B2 - Chest compression training device - Google Patents

Description

The present invention relates to a chest compression training device.

A home training aid for practicing human cardiopulmonary resuscitation (CPR) has been reported (Patent Document 1), which is housed in a non-humanoid housing such as a teddy bear or other stuffed toy. The compression mechanism in this training aid consists of a chest plate, a back plate, and one or more extendable struts, and is designed to be compatible with human CPR.

It has been reported that a portable training device for cardiac massage uses a closed-cell synthetic resin foam as a pressing part that can move up and down inside a schematic chest body (Patent Document 2). This training device is also designed to be suitable for cardiac massage on the human body. In recent years, the term "chest compression" has often been used instead of "cardiac massage," so hereafter this specification will consistently refer to it as "chest compression."

Guidelines published by the Veterinary Emergency and Critical Care Society (VECCS) state that chest compressions should be started as soon as possible after confirming cardiac arrest in dogs and cats, and that it is essential that the technique be performed equally by both members of the public and medical professionals (Non-Patent Document 1). The guidelines also point out that in cats and small dogs, chest compressions can be performed efficiently by wrapping the compresser's fingers around the sternum, where the heart is located, and performing chest compressions with one hand (see Figure 5a).

There is a need for a simple tool that owners and other ordinary people can use on a daily basis to practice performing the necessary chest compressions in the event of cardiac arrest in small pets such as cats and small dogs.

The present invention provides a chest compression training device (hereinafter simply referred to as the "training device") with the external shape of a stuffed animal, in which the stuffed animal is modeled after a small pet animal and a compressible foam is embedded in the area including the chest of the stuffed animal, and which is used to practice chest compressions by grasping the thorax with one hand in order to resuscitate a small pet animal.

The small pet animal in the present invention is preferably a small dog, cat, or rabbit.

The density of the foam in the present invention is preferably 52 to 68 kg/m3. The impact resilience of the foam in the present invention is preferably 33 to 45%. It is more preferable that the density of the foam is 52 to 68 kg/m3 and the impact resilience of the foam is 33 to 45%.

The training device of the present invention has the external shape of a stuffed animal that resembles a small pet, making it easy to visualize the actual chest compressions that are required. Furthermore, because the training device of the present invention has a feel similar to that of a living small pet's chest, it is easy to grasp the actual compression force required when grasping the rib cage with one hand and performing chest compressions. Furthermore, because the training device of the present invention has a simple structure, it is easy for ordinary people, such as owners of small pets, to use for repeated daily training.

Therefore, the present invention provides a training device that allows people to efficiently learn chest compressions on small pet animals through daily practice.

1 is a perspective view of an embodiment of a training device of the present invention.

The present invention will be further described with reference to one embodiment of the training device of the present invention shown in Figure 1.

The training device of the present invention has the external shape of a stuffed toy. The stuffed toy shape makes it easy to handle on a daily basis and is highly effective in encouraging repeated and continuous chest compression practice.

Stuffed toys are made to resemble small pet animals. They may be stuffed toys that faithfully reproduce the appearance of real small pet animals, but they may also have slightly exaggerated or simplified shapes based on the owner's preferences or ease of production.

Small pets are pets that weigh 10 kg or less when grown. Preferred small pets are small dogs, cats, or rabbits.

It is preferable to use a stuffed animal of the same species as the animal the owner owns as a training tool. Owners of small dogs should use a stuffed animal modeled after a small dog, and owners of cats should use a stuffed animal modeled after a cat, making it easier for them to imagine the chest compressions that are actually required for their pet animals.

In particular, with small dogs, there are large differences in appearance depending on the breed, so it is preferable to use a stuffed toy of the same or similar breed as the owner's own dog as a training tool. However, even if the stuffed toy is of a different breed, it can still be effective for training as long as it is roughly the same size as the owner's own dog.

A stuffed animal has a compressible foam embedded in the area including its chest. Figure 1 shows an embodiment in which a rectangular parallelepiped foam 2 is embedded inside stuffed animal 1 modeled after a toy poodle. Foam 2 is a component that provides the sensation of a compressed chest, and is placed inside the stuffed animal in the area including the chest. Specifically, the area including the chest is the area of the stuffed animal's torso that extends from roughly the base of the front legs to the center of the torso in the front-to-back direction.

In the embodiment shown in Figure 1, the foam 2 is positioned so that its front end surface in the front-to-back direction roughly coincides with a plane that is perpendicular to the body of the stuffed animal and passes through the rear ends of both front legs.

Stuffed toys with foam embedded inside can be made through a series of steps: prepare a stuffed toy with the necessary gap left in the body and an opening on the surface, insert foam through the opening and place it in the gap, add a means to secure the foam if necessary, and then close the opening. It is preferable to position the opening on the back of the stuffed toy from the standpoints of ease of inserting the foam and the feel when practicing chest compressions.

Alternatively, a stuffed animal with foam embedded inside can also be made by taking a completed stuffed animal, creating a new opening on the surface, removing the padding or other necessary gaps in the body, inserting foam through the opening and placing it in the gap, using a means to secure the foam in place as needed, and then closing the opening.

One way to secure the foam inside the stuffed toy is to place additional padding around the foam and place it in the gap. For example, when inserting the foam through an opening in the back of the stuffed toy, placing padding on the underside of the rectangular foam (the side facing the stuffed toy's chest) can further improve the feel when practicing chest compressions. In this case, the amount of padding should be, for example, about 20 to 30 mm thick, with a thickness of about 25 mm being particularly preferable.

The shape of the foam is not particularly limited, but from the perspective of ease of production, a rectangular parallelepiped is preferable. When the foam is rectangular, the size is preferably 70 to 120 mm in the front-to-back direction, 50 to 90 mm in the left-to-right direction, and 50 to 90 mm in the up-to-down direction when the stuffed animal with the foam embedded in it is placed in a prone position. The front-to-back length is more preferably 80 to 110 mm. The left-to-right width is more preferably 55 to 85 mm. The up-to-down length is more preferably 55 to 85 mm.

In the embodiment shown in Figure 1, the size of the rectangular foam body 2 is 100 mm in length in the front-to-back direction, 70 mm in width in the left-to-right direction, and 70 mm in length in the up-to-down direction.

Even if the foam is not rectangular, it is preferable that at least one pair of opposing surfaces on both the left and right sides of the stuffed animal's body be approximately flat, from the perspective of the feel when practicing chest compressions. When the foam is not rectangular, the size can be set in accordance with the case of a rectangular shape.

The foam is selected to be compressible and have appropriate elasticity so that it provides a feel similar to that of a live chest of a small pet animal when practicing chest compressions. The foam's properties are preferably a density of 52-68 kg/m3 or a resilience of 33-45%, and more preferably a density of 52-68 kg/m3 and a resilience of 33-45%.

The density of the foam is preferably 54 to 66 kg/m3, and more preferably 56 to 64 kg/m3. The impact resilience of the foam is more preferably 35 to 43%, and even more preferably 36 to 42%. Impact resilience is measured in accordance with JIS K6400-3:2011.

More preferably, the foam has a density of 54 to 66 kg/m3 and a resilience of 35 to 43%. More preferably, the foam has a density of 56 to 64 kg/m3 and a resilience of 36 to 42%.

There are no particular restrictions on the foam material as long as it meets the above-mentioned properties, but urethane or polyolefin is preferred, with urethane being particularly preferred.

By configuring the embedding position, size, and characteristics of the foam as described above, repeated practice using the training device of the present invention makes it easy to understand the actual compression force required when grasping the thorax with one hand and performing chest compressions.

The training device of the present invention has a simple structure in which a specified foam is embedded in a stuffed animal, so ordinary people, such as owners of small pets, can obtain it, keep it close at hand, and use it repeatedly for everyday training without any hesitation.

When transferring or selling the training device of the present invention, it can be provided as a chest compression training kit comprising the training device and instruction means that explains how to practice grasping the rib cage with one hand and performing chest compressions. The instruction means can be a medium such as a printed document or packaging container on which the instruction contents are printed, or a link (two-dimensional barcode, URL, etc.) to electronic information (e-books, videos, etc.) containing the instruction contents, or an electronic medium containing the instruction contents as electronic information, or a combination of these.
