Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to air tight wear that prevents air leakage from the periphery of a dome of a positive pressure ventilator used primarily for patients with chronic respiratory failure.

[Prior art]

Positive pressure ventilators, which assist physiological decompression breathing, are useful for respiratory support for patients with chronic respiratory insufficiency caused by pulmonary fibrosis, emphysema, sequelae of pulmonary tuberculosis, etc., and neuromuscular diseases.

However, conventional positive pressure ventilators are large and heavy, like an iron lung, and even when an armor-shaped dome is attached to the chest as shown in Figure 4, the patient's body shape Since the pressure is different for each patient, air may leak from the gap between the dome periphery (2) and the patient's body surface and sufficient positive pressure cannot be obtained, or the air inside the dome (20) may be exhausted to allow breathing. There were problems such as it taking too much time to reach the positive pressure necessary to support the system. In order to prevent air leakage from the area around the dome (2), there are methods such as wearing a jacket over the dome (20), attaching a rubber tube around the dome, or wrapping plastic wrap in the gap. 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.

[Purpose of the invention]

The present invention secures airtightness by closing the gap around the dome in positive pressure artificial respiration using an armor-shaped dome, which has traditionally had problems with the airtightness of the dome, and also simplifies the dome installation. The purpose of this product is to provide air tight clothing that can be used as an airtight garment.

[Structure of the invention]

That is, the present invention is made of a material that is substantially impermeable to air;
It is a front-opening garment that is worn over an armor-shaped dome for artificial respiration, and has a hole in the front to allow the dome boat to come out when the left and right front sections are closed together. The left and right front body ends (joining parts) each have a closing means, and a position corresponding to the dome periphery on the inside of the front body is a means for closing the gap created around the dome periphery. The air tight wear is characterized by having fastening means on the collar, hem, and left and right cuffs to bring each part into close contact with the body.

Since the main purpose of the air tight wear of the present invention is to prevent air leakage by blocking the gap between the dome periphery and the body surface, it is desirable that the material has low air permeability. In addition, if there is air between the clothing and the body surface, which is a so-called baggy condition, the air may not be able to be handled during the intake period and it will not be effective, or the start of intake assistance will be delayed by that amount. Become. Therefore, it is desirable to use a material that fits the body and has some degree of elasticity. From the above, it is best to use materials such as cotton, nylon, or polyester fabrics that contain about 10 to 15% polyurethane fibers, and if the surface is coated with polyurethane resin, polyvinyl chloride resin, etc.
This is more preferable in terms of airtightness. In addition, knitted fabrics such as knits cannot be used alone due to their high breathability, but if they are coated with polyurethane resin, polyvinyl chloride resin, etc., or treated with a laminated structure, they can become stretchy and breathable. Can be used as a low-cost material. In general, polyurethane nonwoven fabrics and the like can stretch in any direction and have good fit. Therefore, this polyurethane nonwoven fabric may be coated or laminated with polyurethane resin, polyvinyl chloride resin, etc. in the same manner as in the above case.

As for the shape of air tight wear. A front-opening type of clothing that is easy to put on and opens as far away from the dome as possible is best. The air tight clothing of the present invention is worn over an armor-shaped dome, and an entrance/exit (tom port) must be provided somewhere in the clothing to allow air to enter and exit the dome. - Inside the shell, a port will protrude from the center of the dome, and when worn, it will protrude toward the front of the body. Therefore, if it is a front-opening garment, a hole will be made at the joining part of the left and right front sections, and the dome port will be exposed to the outside. Of course, this hole needs to be larger than the diameter that the dome port passes through, but if it is relatively far from the periphery of the dome, it is possible to make the area around the dome air tight. In some cases, the hole may be quite large.

The means for closing the joints of the front body are generally made of an engaging piece (tape) called velcro, which has many loops exposed on the surface, and a number of hook-shaped, mushroom-shaped, etc. protrusions exposed on the surface. It can be closed with a fastener made of an engaging piece (tape) or a slide fastener such as a zipper.

The collar of the air tight wear of the present invention is relatively close to the dome periphery and is a location where air tends to leak. However, if it is tightened too tightly, it will make you feel breathless and will actually reduce the therapeutic effect, so it is made with a high neck type, stuffed with cotton or sponge, etc., and is made with Velcro, a slide fastener, or a stretchable material such as jazzy rubber. It is preferable to use an airtight band made of a certain material as the fastening means.

In addition, it is preferable to have short sleeves so that the veins in the arm can be secured when administering treatment such as intravenous drip, and the cuffs should be fastened with Velcro, airtight bands, strings, etc. to prevent air leakage. Attach the mounting means.

It is also preferable to use Velcro, an airtight band, string, or the like as a fastening means for the hem of the wear to prevent air leakage from the lower end of the dome.

In addition, as mentioned above, it is very important that the wear is in close contact with the surrounding area of the dome, and it is desirable to use Velcro or an airtight band to ensure close contact with the outer wall of the dome. In addition, by attaching a pad made of air-impermeable material to the inside of the front body of the garment at a position corresponding to the area around the dome, or by providing a pocket and inserting the pad during use, you can prevent the air from forming around the dome. It is also effective to close the gaps. This method is very effective when used on the chest area near the dome area, the lower abdomen, and areas from the side of the body to the back, and is particularly effective on the waist area of the flanks, where individual differences are large.

Roughly, as shown in the examples in Figures 1 and 2, attach a fixing band to the outside back or side of the garment, put on the dome, wear the garment, and close the front seam. It is effective to use this fixing band after the wear and tear, as it can bring the wear and the dome, and the dome and the body surface, into closer contact. The fixing band is made of cloth material, string, rubber, etc. with Velcro attached to the tip.

Embodiments of the present invention will be described below with reference to the drawings.

[Example 1] ゛As shown in Figure 1, there is a dome port (22) in the center.
The front body (1) is closed with a Velcro tape (11) designed to have a hole to let it out, and the collar part (13) is fastened with Velcro tape (13).
3), short sleeves (4) whose cuffs can be fastened with Velcro (14), a back body (2) that covers the entire back, and at least one pair of belts or string-like fixed belts attached to the back or sides ( 10), and a Velcro tape (19) is attached to the part that comes into close contact with the dome periphery (2).

Of course, the size of the hole provided in the front body (1) for letting out the dome port (22) connected to the yin-positive pressure generator should be larger than the outer diameter of the dome port (22). For the purpose of airtight, a major problem is how to bring the dome peripheral part (21) into close contact with the body surface, and as shown in FIG. 1, the hole in the center may be quite large. And, on the back side of the front body (1), there is a Velcro tape (19
) is attached so that it can be closely attached to the Velcro attached to the dome periphery (21).

In addition, as shown in Figure 1, the collar part and hem part (5) following the collar part (3) press down on the head and leg side edges of the dome (20) and are designed to prevent air from leaking. Wide Velcro tapes (13) and (15) of about 5 to 10 cm are attached so that patients of different sizes can fit closely together. Collar (3)
has a so-called high neck shape, and the front body (
It connects from 1) and comes with Velcro, but if you tighten the collar too tightly, it will make it difficult to breathe, so as the name suggests, we put cushioning material such as cotton or sponge in it.
It has a shape that allows it to fit.

Further, the sleeves are short-sleeved so that veins can be secured for treatment such as intravenous drip, and are fastened with Velcro (14) to prevent air leakage.

Considering that the patient will be lying on his/her back during treatment, it is preferable not to attach anything that will hit the back, but a dome (
In order to hold the dome (20) and fix the body surface and the dome (20), two pairs of fixing bands (10) were attached to a portion of the back body (2) near the body side. The fixing band (2) may be a string-like thing that can be tied in the front, or a band-like cloth material that can be fixed with Velcro or the like, and the attachment position is around the front body (
It may also be the seam part between 1) and the back body (2).

[Example 2] As shown in Figure 2, the front body (1) opens and closes with Velcro, the short sleeves (8) fasten with Velcro (14), the back body (2) that covers the entire back, It consists of a pocket (9) attached to the side and three pairs of strap-like fixed bands (10) attached to the back or sides, and the pocket (9) is equipped with a pad made of a material with low breathability. Insert and use as necessary.

Compared to Example 1, the hole for letting the dome port (22) out is made almost the same size as the dome port (22), and the front body (1) is shaped to wrap around the entire dome. Also, instead of attaching Velcro to the hem, a string is used as a fixing band (10) to tighten it.

[Example 3] As shown in Fig. 3, the overall shape of the garment is almost the same as in Example 1, and the portion that corresponds to the peripheral surface of the dome (20), the collar (3), and the cuffs (6) are elasticated. Using airtight bands (17) and (18) made of highly flexible rubber material,
In addition, a slide fastener (16) was used to close the left and right front bodies (1).

In addition to rubber, chassis materials can be used without any problem as materials with high shrinkage properties, and the material is not limited to these materials.

(Effects of the Invention) By using the air tight wear of the present invention, a dome that matches the body shape to some extent can be used in positive pressure ventilators, which conventionally required preparing multiple types of domes that matched the body shape of each individual patient. By using the Air Tight Wear, the gap created by the Air Tight Wear is closed and the desired positive pressure is achieved.It also eliminates the need to take an impression of the patient's body and is sufficient for emergency respiratory support. , extremely useful in the medical industry.
