Since the capacity, container diameter, height, etc. of the oxygen cylinder to be carried differ depending on the oxygen prescription flow rate and travel time absorbed by the patient, it can respond to changes in various cylinder shapes, and the patient himself can easily check the remaining amount of oxygen cylinder In order to ensure the normal operation of valves and medical devices such as high-pressure gas regulators and breath-synchronized regulators, the bag is airtight so that it does not splash directly into the bag even when used in wet environments such as rainy weather. It has various problems such as ensuring performance, ensuring air permeability so that oxygen does not stay in the bag, and protecting the remaining amount display means particularly when the bag falls.

  Changes in the shape of the cylinder and the remaining amount of the cylinder can be easily visually recognized, the problems of improving the air tightness of the bag, preventing oxygen retention in the bag, and protecting the bag contents are not compatible. The patient himself is paying attention while solving the problems of the department.

  The present inventor has solved the above-mentioned problems of conventional oxygen cylinder carrier bags, and has found a carrier bag for the following portable oxygen cylinder system.

  That is, the present invention is a bag for storing a portable oxygen cylinder system that supplies oxygen to a user through a flow regulator such as a valve, a high-pressure gas regulator, and a breath-tuned regulator, and a cannula from an oxygen cylinder, Provided is a portable oxygen cylinder carrier bag characterized in that a transparent resin dome-shaped see-through portion is provided at the top of the bag, and a first opening is provided at the bottom of the see-through portion.

  Embodiments according to the present invention will be described below with reference to the drawings. FIG. 1 is an external view of an oxygen cylinder carrier bag of the present invention. Such a bag is a substantially square bag having a roundness in the upper surface direction. However, such a shape may be created in various shapes such as a round shape in accordance with each design design.

  It is important that the material of the carrier bag is a synthetic fiber such as nylon or polyester, a synthetic resin such as vinyl chloride, water repellency or waterproofness, or waterproof processing such as acrylic waterproof coating or polyurethane waterproof coating, It is preferable to use a cloth subjected to water repellent treatment such as fluorine resin coating or silicon resin coating.

  The upper part of the carrier bag is provided with a dome-shaped see-through part that can check the amount of oxygen remaining in the oxygen cylinder. The see-through part is composed of a transparent resin molded member, and uses a thermoplastic elastomer resin (TPE) such as vinyl chloride resin, styrene, olefin, urethane, or ester, especially thermoplastic polyurethane resin (TPU). Accordingly, a dome-shaped or bowl-shaped molded body having transparency, excellent impact resistance and wear resistance, and high elasticity and mechanical strength can be produced. The shape of the dome may be a hemispherical dome shown in FIG. 1 or a square dome, and may be created in accordance with the design design at that time.

  The fluoroscopic part is provided at a position where the remaining amount and residual pressure of the oxygen cylinder stored in the carrier bag, the display contents of the oxygen flow regulator such as a valve, a high pressure gas regulator, and a breathing tuned regulator can be visually recognized. . It is preferable to provide the cylinder bag at a position corresponding to the upper part of the cylinder in front of the cylinder bag.

  Further, with respect to the see-through portion, it is possible to mask the transparent resin portion other than the portion to be seen through by painting or the like. In addition, by applying water-repellent processing to the fluoroscopic part, repel rain and suppress dirt on the fluoroscopic part, and by performing processing such as applying a textured film to suppress light reflection, Visibility can also be improved.

  The dome-shaped see-through portion is not installed in a sealed state with respect to the bag fabric, but includes a first opening. For example, in the carrier bag of FIG. 1, the entire circumference of the dome-shaped resin molding member forming the see-through portion is not sewn together with the bag fabric, but the lower side of the hemispherical dome is between the front of the bag, so-called With an arcuate opening. The shape of the opening is appropriately designed based on the dome shape. In addition, it is also possible to form an opening by providing a plurality of aperture holes opened downward below the dome-shaped see-through portion.

  By providing the first opening, the upper space in the bag can be circulated with the outside air, and even if a part of the oxygen gas in the oxygen cylinder leaks, the outside air does not stay in the bag. The mixture can be diluted and discharged to the outside air. The part where oxygen leaks is limited to the flow regulator such as a high-pressure gas regulator and a respiration tuned regulator and its connection from the valve at the top of the cylinder, and is concentrated in the upper part of the oxygen cylinder, that is, the upper space of the carrier bag. An opening is provided in the see-through part for visually recognizing the set value of the container, the cylinder fuel gauge or the residual pressure gauge.

  Since oxygen is heavier than air, it tends to stay below the bag. However, when the cylinder is stored in the carrier bag, the lower part of the bag is filled with a cushion member to prevent the impact of the oxygen cylinder system. Since the gap is extremely small, most of the oxygen gas leaked from the upper part of the cylinder is discharged to the outside through the first opening by providing an opening in the upper part of the bag.

  Oxygen cylinder carrier bag is equipped with various machine control and electronic control parts as a flow regulator, so there is a measure to prevent water from entering the bag directly from the vent even if it is carried in rainy weather. is necessary. The first opening provided in the dome-shaped see-through portion is always provided in the lower part of the dome. In the case where an arcuate opening is provided, it is possible to prevent rainwater from entering from the side by sewing the see-through opening and the front edge of the fabric with overlapping end faces. When the overlapping portion is increased, the field of view of the fluoroscopic portion is narrowed. However, it is preferable to produce the portion having an overlap of 0.5 cm or more, preferably 1 cm or more. In the case of providing an opening, one or more opening holes are provided in the lower part of the dome with a size that can ensure sufficient ventilation.

  The inner surface of the carrier bag is preferably designed to be as close as possible to the oxygen cylinder to be mounted. By providing a space between the cylinder and the inner surface of the bag, the cylinder itself can move during transportation, causing backlash and vibration, and also causing contact damage with the flow rate regulator. When using a cylinder with a different shape, or when there is a play space between the cylinder to be used and the inner surface of the bag, attach the cushion material to the inner surface of the cylinder with a hook or hook-and-loop fastener so that it can be removed. By limiting the range of motion of the cylinder, it can have a function of absorbing shock.

  The height direction can also be adjusted by providing a cushion material at the bottom of the cylinder. For a cylinder having a large capacity, it is preferable to provide a member having improved cushioning properties in order to mitigate the impact at the time of cylinder replacement.

  In addition to the first opening provided in the carrier bag see-through portion, the lower portion of the carrier bag is preferably provided with a second opening as an air hole. If the lower part of the cylinder is completely in close contact with the inner surface of the bag, the leaked gas will not stay in the lower part of the bag, but if there is a small space, oxygen gas may stay there. Therefore, by providing an opening at the lower part of the carrier bag, air permeability with outside air is ensured and oxygen gas can be discharged. However, since the carrier bag is often mounted on a cart and transported, the lower part of the bag is close to the ground, so that it is necessary to take measures for waterproofing to prevent intrusion of rainwater and the like.

  As the second opening, an opening using a mesh structure member as shown in FIG. 6 can be used. In order to prevent the intrusion of rainwater and the like and to improve waterproofness, it is possible to use a fine mesh size and further apply a water repellent finish. However, the mesh structure with such water-repellent finish cannot completely prevent water from entering, and the fine mesh structure has the disadvantage that the air permeability is worsened. The mesh diameter is determined from the viewpoint of In addition, a slit-shaped opening as shown in FIG.

  As shown in FIG. 4, a pocket or dome having an opening on the outside of the second opening, as shown in FIG. Alternatively, it is possible to prevent rainwater from entering the mesh by providing the cover member having a bowl shape. With respect to such a cover member as well, it is possible to prevent repelling water from entering by providing an overlapping portion with the mesh opening. Such a second opening can be provided in the lower part of the carrier bag, particularly on the left and right side surfaces as long as the design of the bag is not affected. The front side affects the design and is easy for water to enter, and the back side may close between the cart or the back when it is carried as a backpack.

  INDUSTRIAL APPLICABILITY The present invention can be used as a bag used when the patient himself / herself carries an oxygen cylinder used by a patient with respiratory disease for oxygen inhalation therapy.
