DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a dome for a positive pressure ventilator used mainly for patients with chronic respiratory failure.

Positive pressure ventilators that support physiological positive pressure breathing are useful for providing respiratory support for patients with chronic respiratory failure due to pulmonary fibrosis, emphysema, sequelae of pulmonary tuberculosis, etc., and neuromuscular diseases.

However, conventional positive pressure ventilators are large and heavy, similar to an iron lung, and even with an armor-shaped dome, the body shape of each patient is different, so the dome and patient's body There are problems such as air leaking from the gap between the dome and the surface, making it impossible to obtain sufficient positive pressure, or it taking too much time to exhaust the air inside the dome and reach the positive pressure necessary to support breathing. there were. In order to prevent air leakage from the periphery of the dome, methods such as wearing a jacket over the dome, attaching a rubber tube around the dome, or wrapping plastic wrap around the gap have been devised. However, none of these methods were satisfactory, as they were not sufficiently effective in preventing leakage, and the time required to reach the required positive pressure was extended due to the expansion and contraction of jackets, tubes, etc.

That is, in the present invention, an air seal portion is formed by attaching a donut-shaped bag made of an airtight material to the peripheral edge of a dome body made of a hard material and having an opening for connecting to a duct, and the donut-shaped bag is a respirator dome characterized by having a vent for removing air from inside the bag and being filled with particulate material.

The dome of the present invention has an external shape as shown in Fig. 1, and as shown in Fig. 2, it is attached to the patient's chest like armor and inflates the chest by applying positive pressure inside the dome. Something that aids breathing and is large enough to cover at least the anterior chest;
It is necessary to have a suitable shape, and it is more preferable if the shape covers the abdomen and side abdomen. In addition, it covers the front and both sides of the body, and the back is not covered with a dome so that it is convenient for sleeping.As shown in Figure 2, there are bands (5), (6) made of rubber or leather. It would be preferable to have a structure that allows for easy installation.

In the dome of the present invention, it is necessary to maintain positive pressure inside the dome at least during the inhalation time. It is necessary to have a shape that matches the unevenness of the body and prevent air leakage. Therefore, the dome body (1) has a donut-shaped bag made of an airtight material at the periphery, and has a degassing port (4) for removing the air inside the bag, and is filled with particulate matter. Install the air seal part (3).

This air seal part (3) is used to prevent particulate matter from forming when air is present together with particulate matter in the bag, as in the method used in simple fixation devices (Japanese Patent Publication No. 44-5501) used mainly in orthopedics. can move around freely, and simply adjusting it to the patient's body can fill in the gaps. Once the shape of the air seal part (3) fits the patient's body shape, when the air inside the bag is removed from the air release port (4) using a positive pressure pump, the particulate matter becomes tightly packed together with the bag body, causing the shape to change. It becomes as if it were a single individual. Therefore, since there is no gap with the body surface and it does not easily deform even under positive pressure, the inside of the dome can be brought to positive pressure more quickly than in conventional domes.

The airtight material forming the donut-shaped bag of the air seal part (3) is preferably a material that expands and contracts according to the body shape and can fill the gap between it and the body surface, such as vulcanized rubber such as natural rubber or synthetic rubber. , polystyrene-based, polyolefin-based,
Various thermoplastic elastomers such as polyester, polyurethane, and polybutadiene can be used, but
There are no particular restrictions on the material as long as it is an elastic material. Alternatively, it may have a double membrane structure in which the inner surface is made of a relatively hard and high molecular weight material, and the outer surface is made of a flexible material with good adhesion.

By doing so, it is possible to prevent the plasticizer and the like contained in the particulate matter in the air seal portion (3) from penetrating and deteriorating the airtight material forming the bag. Roughly,
It is also possible to use a somewhat thicker and more elastic material for the part that comes into close contact with the body.

The granular material to be filled into the donut-shaped bag of the air seal part (3) is made of materials such as polystyrene resin, polyethylene resin, polyvinyl chloride resin, polyurethane resin, and phenol resin, and can also be made of foam to reduce weight. good. Furthermore, for the same reason, porous ceramics such as pumice and vermiculite, and porous materials such as ferrite and pearlite can also be used. In order to evenly fill the entire donut-shaped bag with these particulate materials, for example, a partition wall with openings that allow air to pass through but not particulate materials should be provided inside the bag, or a long and thin thread-like material should be provided inside the bag. It is also effective to pack the material through it.

The dome of the present invention can be fitted to match the patient's body shape and the unevenness of the body surface, and can be adjusted to MW so that no gap is created between the body surface and the dome periphery, unlike conventional domes. In addition, it is possible to provide a dome that can be immediately adapted to any patient, rather than a custom-made dome that is made to suit each patient's body shape. Moreover, the air seal part does not deform even under the positive pressure of a positive pressure ventilator during use, and can quickly create positive pressure inside the dome, making it extremely useful in the medical industry for providing more effective respiratory support than ever before. It is excellent.

The dome of the present invention having the shape shown in Fig. 1 is placed on the front chest of a patient with chronic respiratory failure by passing both arms through the band (5) as shown in Fig. 2, and placing both ends along the lateral chest. After tightening the back band (6) to fit the dome to the patient's body, use a positive pressure pump to pump the air seal part (3) through the degassing port (4).
The air inside the bag that makes up the air is treated. By doing this, the air seal part (3) is in close contact with the body, preventing air from leaking, leaving space in the dome body (2) for the ribcage to move, and the inside of the dome is completely sealed. Ta.

If the dome of the present invention is to be used again on the same patient, it is sufficient to maintain the positive pressure inside the bag of the air seal part (3) after removing it from the patient's body, unless particularly strong force is applied. Since the shape that matches your body shape will not change, you can simply put it on again and it will fit tightly to your body as it was when you first put it on. In addition, when using it on another patient, the particulate matter filled inside becomes fluidized by introducing air into the bag of the air seal part (3), so it must be attached again using the procedure described in the example. This allows for close contact with the new patient's body.
