Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to air tightwear that prevents air leakage from the periphery of a dome of a negative pressure respirator used primarily for patients with chronic respiratory failure.

[Prior art]

Negative pressure ventilators that support physiological negative pressure 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 negative 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 individual, air may leak from the gap created between the dome periphery 2 and the patient's body surface and sufficient negative pressure may not be obtained, or the air inside the dome 20 may be exhausted to assist breathing. There were problems such as it taking too long to reach a negative pressure. In order to prevent air leakage from the dome periphery 2, methods such as wearing a jacket over the dome 20, attaching a rubber tube around the dome, or wrapping a wrap around the gap have been devised. However, these methods were unsatisfactory because they were not sufficiently effective in preventing leakage, and because the jacket and tube expanded and contracted, it took a long time to reach the necessary negative pressure.

[Purpose of the invention]

The present invention secures airtightness by closing the gap around the dome in negative 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 wear that can be used in a variety of ways.

[Structure of the invention]

That is, the present invention is a front-opening garment made of a material that does not allow air to pass through and is worn over an armor-shaped dome for artificial respiration. It has a hole for allowing the dome port to come out when they are closed together, and has closing means at the ends (joining parts) of the left and right front sections, and at least the collar, hem, and left and right ends. In air tight wear, each cuff has a fastening means to make each part adhere to the body, and has a pad or a pocket for storing the pad as a means to close the gap created around the dome on the inside of the front body. This air tight wear is characterized by:

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 escape during the intake period and it will not be effective, or the start of intake assistance will be delayed by that amount. . Therefore, it is desirable to use a material that fits the body and has some degree of elasticity. From the above, cotton made with about 10 to 15% polyurethane fiber,
A material such as nylon or polyester fabric is preferable, and it is more preferable to coat the surface with polyurethane resin, polyvinyl chloride resin, etc. from the viewpoint of airtightness. In addition, knitted fabrics such as knitted fabrics 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. Furthermore, polyurethane nonwoven fabrics and the like can stretch in any direction and have good fitting properties. 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 the air tight wear, a front-opening type of clothing that is easy to wear and opens as far away from the dome as possible is recommended. The air tight wear of the present invention is worn over an armor-shaped dome, and an inlet/outlet (dome port) must be provided somewhere in the wear to allow air to enter and exit the dome. Generally, the 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 not necessary to make it air tight around this hole by making 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 an engaging piece (tape) with many loops exposed on the surface, called Magic Tape (registered trademark), and a large number of hook-shaped, mushroom-shaped, etc. protrusions on the surface. It can be closed with a velvet type fastener consisting of an exposed engagement piece (tape) or a slide fastener such as a zipper.

The collar portion of the air tightwear of the present invention is relatively close to the dome periphery, and is a location where air is likely 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 of a high neck type, filled with cotton or sponge, etc., and is used as a velvet-type fastener, a slide fastener, or a zipper-type fastener that expands and contracts like jersey rubber. It is recommended 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 wrapped with velvet fasteners, air tight bands, strings, etc. to prevent air leakage. Install the fastening means.

It is also preferable to use a velvet fastener, airtight band, string, or the like as a fastening means for the hem of the wear to prevent air from leaking 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 velvet fasteners, airtight bands, etc. to ensure close contact with the outer wall of the dome. In addition, by attaching a pad made of an air-impermeable material to the position corresponding to the area around the dome on the inside of the front body of the garment, 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.
It is especially effective in the waist area of the flanks, where individual differences are large.

Furthermore, as in the examples in Figures 1 and 2, a fixing band is attached to the outer back or side of the garment, the dome is attached, the garment is worn, and the front seam is closed. Later, if this fixing band is used, it is effective to bring the wear and the dome, and the dome and the body surface, into closer contact. The fixing band is made of cloth material with a velvet fastener attached to the tip.
Made of string, rubber, etc.

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

Embodiment 1 As shown in FIG. 1, the front body 1 is a velvet type fastener 11 that is closed with a velvet type fastener 11 designed to have a hole in the center for letting the dome port 22 out. A collar 3 fastened with a fastener 13, short sleeves 4 whose cuffs are fastened with a velvet fastener 14, a back body 2 that covers the entire back, and at least one pair of belts or string-like fixing bands attached to the back or sides. 10, and a velvet fastener 19 is attached to the portion that is in close contact with the dome peripheral portion 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, but for the purpose of Air Tight, A major problem is how to bring the dome peripheral portion 21 into close contact with the body surface, and as shown in FIG. 1, the hole in the center may be quite large. and,
A velvet type fastener 19 is attached to a part corresponding to the dome peripheral part 21 on the back side of the front body 1, so that it can be closely attached to the velvet type fastener attached to the dome peripheral part 21.

In addition, as shown in Fig. 1, the collar part and hem part 5 following the collar part 3 press the edges of the head and leg sides of the dome 20 and fit tightly even for patients of different sizes to prevent air from leaking. A wide velvet type fastener 13, 15 of about 5 to 10 cm is attached to make it possible. The collar part 3 has a so-called high neck shape, and is connected to the front body part 1 with a velvet fastener.However, if the collar part is tightened too tightly, it will become difficult to breathe, so the name suggests that cotton or velvet fasteners are attached. A cushioning material such as sponge was added to create a snug shape.

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

Considering that the patient lies supine during treatment, it is preferable not to attach any objects to the back that would hit the back, but in order to hold the dome 20 and fix the body surface and the dome 20, two pairs of A fixing band 10 was attached to a part of the back body 2 near the side of the body. The fixing band 2
It can be a string-like thing that can be tied in the front, or a band-like cloth material that can be fixed with a velvet fastener, etc., and the attachment locations are front body 1 and back body 2.
It is also possible to use the seamed parts.

Embodiment 2 As shown in Fig. 2, the front body 1 opens and closes with a velvet fastener, the short sleeves 8 are fastened with a velvet fastener 14, the back body 2 covers the entire back, pockets 9 attached to the back side, and It consists of three pairs of strap-like fixing bands 10 attached to the back or sides, and a pad made of a material with low air permeability is inserted into the pocket 9 as needed.

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. Instead of attaching a velvet type fastener to the part, a string is used as a fixing band 10 to tighten it.

Example 3 As shown in FIG. 3, the overall shape of the wear was almost the same as in Example 1, and the peripheral part of the dome 20, the collar 3, and the cuffs 6 were made of highly elastic rubber material. Airtight bands 17 and 18 were used, and slide fasteners 16 were used to close the left and right front body parts 1.

In addition to rubber, jersey can be used without any problem as the highly contractible material, and the material is not limited to these materials.

〔Effect of the invention〕

By using the air tight wear of the present invention, it is now possible to use a dome that matches the patient's body shape to some extent in negative pressure ventilators, which conventionally required preparing multiple types of domes to suit the body shape of each individual patient. For example, the gap created by the velvet fastener is closed with airtightwear to obtain the desired negative pressure. Furthermore, it is extremely useful in the medical industry because it saves the time and effort of taking a mold of the patient's body and can adequately handle emergency respiratory support.
