圧呼吸を補助する除圧式人工呼吸器が有用である。BACKGROUND OF THE INVENTION A decompression ventilator that supports physiological decompression breathing is useful for providing respiratory support for patients with chronic respiratory failure due to pulmonary fibrosis, emphysema, sequelae of pulmonary tuberculosis, etc., or neuromuscular diseases.

法ではない。However, conventional depressurizing respirators are large and heavy, like an iron lung, and even if they are made with an armor-shaped dome, air leaks from the periphery of the dome, so the air inside the dome is exhausted. There have been problems such as it takes time to reach the positive pressure necessary to support breathing, or the body surface near the opening for pulling with positive pressure twitches. In particular, to prevent air leakage from the periphery of the dome, methods such as wearing a jacket over the dome or wrapping plastic wrap over the periphery of the dome have been adopted, but neither method is satisfactory. .

供することを目的としたものである。The present invention prevents air leakage from the periphery of the dome of armor-type positive pressure respirators, which have conventionally had problems with the dome's structure such as airtightness, and quickly restores the predetermined positive pressure inside the dome. The purpose of this invention is to provide a positive pressure ventilator that can reduce the pressure to a normal pressure.

るものである。That is, the present invention provides a dome for a respirator, characterized in that a tube made of a rubber material is attached to the periphery of a dome body made of a hard material and having an opening for connecting to a duct at the top; , a plurality of screws are buried so as to pass through the tube wall outward from the inner cavity of the tube made of a rubber material, and placed in positions corresponding to the screws on a flange provided on the peripheral edge of the dome body made of a hard material. The present invention relates to a method for assembling a dome for a respirator, which comprises drilling a hole, fitting the screw into the hole, and fastening with a nut.

It is attached to the patient's chest like armor and applies positive pressure inside to inflate the chest and assist breathing, so it needs to be sized and shaped to at least cover the anterior chest area. Furthermore, it is more preferable if the shape covers the abdomen and the thoracotomy abdomen. In addition, the material may not be particularly limited as long as it is a hard material that does not deform even when positive pressure is applied during use, but light metals such as aluminum alloys, hard vinyl chloride resin, methacrylic resin, polycarbonate resin, etc. It is desirable to use a relatively light material with high strength, such as a thermoplastic laminate molded product such as polyamide resin, reinforced plastic (FRP), or carbon fiber reinforced plastic (CFRP).

５０ｇ／ｃｒＡの範囲が望ましい。In order to prevent air leakage from the periphery of the dome, the periphery leading to the upper edge of the symphysis pubis must be fitted to the irregularities of the body, and the periphery of the domes (1) and (8) must be made of rubber material. These problems are solved by installing tubes (2) and (5). As the rubber material, in addition to so-called vulcanized rubber such as natural rubber and synthetic rubber, various thermoplastic elastomers such as styrene, olefin, ester, urethane, and polybutadiene are preferably used. In addition to air, the container may be filled with a foam material such as urethane sponge, water, ethylene glycol, liquid paraffin, polyvinyl alcohol aqueous solution, glycerin, or the like. In particular, when a highly viscous liquid is injected, the compliance of the dupe decreases and the rate of deformation when positive pressure is applied decreases, allowing the interior of the dome to lower to the desired positive pressure more quickly. . However, it has the disadvantage that the entire dome becomes heavier, so it is generally preferable to inject air into it. In addition, if the tube is filled with a foam material such as urethane sponge, it is possible to soften the contact between the hard dome and the body surface.
This foam material has a compressive strain of 5 to 5 at 25% compression.
A range of 50 g/crA is desirable.

埋設する。You can also use adhesive to fix the tube to the dome, but the adhesive surface tends to peel off due to friction with the body surface when the dome is in use. The tube (5) is bonded with adhesive or heat welded from the inside of the tube (5), and screws are embedded so as to penetrate the tube wall from the inner lumen of the tube to the outside.

接合面がはがれてしまうこともない。Next, as shown in Fig. 1, a plurality of screws (3) are buried along the entire length of the tube (2) and the dome (1
) is provided on the periphery of the flange at a position corresponding to the screw, and the screw (6) is fitted into this hole and fastened with the nut (4) from the opposite side of the flange. After this, if air, etc. is injected into the tube (2) and it is expanded, there will be no gaps between the body surface and the tube, and between the tube and the dome, and there will be almost no air leakage even when yin-positive pressure is applied. There is no risk of the dome coming off when it is attached or removed, and the joint surface between the tube and the dome will not come off.

感をなくすことができる。In order to create a positive pressure inside the dome of the present invention and perform artificial respiration, a duct is connected to the opening at the top, and the air inside the dome is sucked out with a blower or air is supplied. For the purpose of assisting breathing, the pressure inside the dome changes between positive pressure and atmospheric pressure at intervals of 1 to 2 seconds, so a fairly large-capacity blower is required to suck the air inside the dome in a short period of time. is necessary. Therefore, if the area of the opening is narrow and there is only one opening, the body surface in the vicinity may twitch, causing discomfort to the patient. Therefore, as shown in Figure 3, by providing two or more openings (9) at the top of the dome, the air inside the dome can be sucked in evenly, or by using a partition plate with many holes in the dome. It is preferable to take measures such as providing a pressure distribution to eliminate bias in the pressure distribution. By using this method, it is possible to prevent the gradual application of positive pressure and the unpleasant feeling of twitching on the body surface that is seen with conventional domes, thereby eliminating the discomfort caused by long-term use. can.

The chest begins to swell almost simultaneously with the start of suction, providing effective respiratory support, and has a particularly excellent structure as a dome used in positive pressure artificial respiration, making it extremely useful in the medical industry.

感触もなかった。At the periphery of the dome, fixing screws are embedded in a butyl rubber tube, and screws are provided at the part where the dome and the body surface meet, that is, at the flange, so that the device can be installed according to the curve of the dome. A hole was made and the dome was tightened with a cap nut from the outside.After this, air was introduced into the tube to inflate it and give it appropriate elasticity.The opening of the dome was made as shown in Figure 3. A blower with a capacity of 1.4 m/min was attached to the chest of the person on the inside of the partition panel at five locations, and the air was repeatedly sucked and discharged.As a result, almost no air leakage was observed from the periphery of the dome. The target value is -10 to -20 approximately 0.4 to 0.7 seconds after the start of positive pressure.
It was confirmed that positive pressure of mHO was reached and that breathing assistance could be provided immediately. Furthermore, there was no twitching sensation on the body surface during suction.
