Description

  The present invention relates to a cassette used for X-ray imaging in the medical field, or a cover covering a protective cover for storing the cassette.

As a cover for storing an X-ray imaging cassette, Japanese Patent Application Laid-Open No. 2006-293368 (Patent Document 1) proposes an “image detector cover”. The cover disclosed in Patent Document 1 is for protecting the image detector from being damaged due to an unexpected drop, etc., and is provided with a solid, rigid and lightweight material such as a plastic or a structural composite material. The purpose is to protect the detector.
By the way, because the image detector is used multiple times for X-ray imaging of hospitalized patients, if used inadvertently by MRSA infected persons, it may infect other patients, resulting in an increase in nosocomial infections. There is a risk of going.
In addition, X-ray imaging in a hospital room has a problem that a hard cassette hits the spine of a patient who is supine and is painful.
JP 2006-293368 A

  In view of the above circumstances, the present invention accommodates the cassette itself and a protective cover having a strong rigidity for storing the cassette and gently touches the patient during use for X-ray imaging, and is safely discarded after use. It is intended to provide a cassette cover that prevents the spread of contamination infections due to photography.

The cassette cover according to claim 1 of the present invention has a rectangular parallelepiped shape that is a vertically long rectangular shape in a plan view, one side of a bag body made of a flexible water-retaining material and the other side made of a sliding waterproof material. A lid provided at the top is openable and closable, and a pull-in piece protrudes from the inner surface of the bottom surface at the other end in the longitudinal direction. The upper and lower surface portions of both side surfaces are folded along the longitudinal direction. It is stitched so that it can be overlapped, and a thick cushion material is disposed at the other longitudinal end of the upper surface.
The cassette cover described in claim 2 is the cassette cover described in claim 1, wherein a cross mark is provided at the upper surface part 4 dividing point of the bag body, and a corner part extending from both side surface parts to the upper surface part is provided. Is formed by arranging an inverted L-shaped mark in phase with the horizontal base line of the cross mark.

  According to the cassette cover of the present invention, bacteria and contaminants when using the cassette do not adhere to the cassette, so that it can be used hygienically multiple times for a plurality of people, and the pain at the time of photographing is alleviated. .

The bag body in the present invention is basically composed of an upper surface portion made of a flexible material (longer than the size of the lower surface portion as long as the size of the lid), a lower surface portion, and both side surface portions. Are sewn at the upper and lower corners, and both are sewn with a seam margin so as to form a pull-in piece on the central inner surface in the height direction of the bottom surface, It is stitched at the corner. At this time, the material selected is made of a water-proof material that is water-slidable on one side, such as JMS sheets (product name) or paper diapers, and the other side is water-retained that keeps water through. However, the bottom surface side may be a sliding waterproof material except for the water retaining material.
When sewing each member, considering the state when used as a cassette cover, the water retaining material side faces the outer surface because the outer surface contacts the human body at the upper surface (which covers half of the bottom surface) and the side surface. Since the outer surface of the lower surface portion is a surface that comes into contact with the bed, the sliding waterproof material side such as nylon having a low frictional resistance is directed to the outer surface so that each portion is sewn in order to facilitate slipping.
The formation of the bag body is not limited to the above-described stitching, but the whole body is made of a slippery and slippery material so that it can easily move on a table or a bed. It is easy to insert blends (lead grids) etc., and water-retaining materials are attached to the outer surface of the top surface, both side surfaces, and the bottom surface. It is partly joined from what goes on.
Also, some adhesive tapes involved in opening and closing the lid on the upper surface part are provided at a plurality of locations in the width direction from one at the center. The cushion material disposed on the bottom surface side of the top surface portion is filled with a flexible rubber material or sponge material.

  The cassette cover A of the present invention will be described with reference to an embodiment. As shown in FIG. 1, a material described later is used as a rectangular parallelepiped bag having a width of 400 mm, a length of 470 mm, and a height of 20 mm. The upper surface portion 1 (longer than the lower surface portion 3 by 100 mm as the lid 2), the lower surface portion 3 and both side surface portions 4 are formed. Both corners are sewn together, and both are sewn at the center in the height direction of the bottom surface portion 5, and a seam allowance is formed on the inner surface as a retractable piece 6. As for these materials, a material such as a JMS sheet or a disposable diaper on the upper side of the upper surface portion 1, the lid 2, and the side surface portion 4 is made of nylon and a sliding waterproof material, and the other surface is made of a water retaining material. For the lower surface portion 3, only one having a sliding property is used. The upper surface portion 1 and both side surface portions 4 are sewn in the manner described above with the water retaining material side facing the outer surface and the bottom surface portion 5 facing the waterproof material side toward the outer surface. A thick cushion material 7 is attached to the upper surface of the upper surface portion 1 near the bottom surface portion 5, and one end of the adhesive tape 8 is bonded to the upper surface of the lid 2 in the center in the width direction. Further, a cross mark 9 made of black lines is attached to the central four-divided point of the upper surface portion 1, and an inverted L-shaped mark 10 made of black lines is attached to the corner portions extending from both side surface portions 4 to the upper surface portion 1. Arranged in phase with the horizontal baseline.

The cassette cover A thus configured accommodates both the cassette itself or the cassette stored in a rigid protective cover and the Lisholm blende during X-ray imaging of a patient in a medical facility. The closed lid 2 is fixed to the lower surface portion 3 with the adhesive tape 8.
In this state, X-ray imaging is performed with the opening 11 of the cassette cover A facing the patient's head in the supine position and the bottom surface 5 facing the patient's foot with the region of interest of the patient. . In chest X-ray photography, the back (bottom side) of the cassette cover A is in contact with the patient's spine or lumbar spine. Both side surface portions 4 are folded at the gusset portion according to the weight of the patient.
There is a possibility that the entire outer surface of the cassette cover A after the X-ray imaging is contaminated with bacteria and dirt. Therefore, the adhesive tape 8 is peeled off from the lower surface 3, the lid 2 is opened, and an image detector (not shown) such as a cassette is carefully taken out from the opening 11, and then the inside of the empty cassette cover A is opened from the opening 11. When one hand is put in and the pulling piece 6 on the inner surface of the bottom surface part 5 is gripped, and the opening 11 is grasped by the other hand and the pulling piece 6 is pulled out, the cassette cover A is shown in FIG. Is reversed, and bacteria and dirt attached to the outer surface of the outside are trapped inside. This is folded down appropriately, and is stopped with the adhesive tape 8 and discarded in the waste container.
In this way, the cassette and the cover for storing the cassette are used hygienically without causing pain to the patient, and the cassette cover A after use is safely discarded, eliminating problems such as nosocomial infections due to radiography. Is done.

  The cassette cover A according to the present invention can contribute to X-ray imaging safely in terms of hygiene, and since pain during imaging is alleviated, it is required by medical facilities and contributes to the activation of the medical related industry.
