Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening holder for a cassette storage bag, and more particularly to a bag opening holder for a cassette storage bag for holding a cassette storage bag for storing a cassette used in X-ray photography in the medical field in an open state of the bag mouth.

In X-ray photography in the medical field, an X-ray film using silver salt or a storage used in computer X-ray photography (CR) as a storage medium for displaying the intensity of X-rays transmitted through the subject's body as a grayscale image. Fluorescent sheet (imaging plate (radiation detector; IP)) is used. Recently, an X-ray flat panel detector (flat panel detector: FPD) used in DR (digital radiography) that directly converts X-rays into electrical signals and has been proposed has also been proposed.
X-ray storage media such as X-ray films, imaging plates, and X-ray flat panel detectors are usually handled in a rectangular panel case called a cassette in order to prevent surface contamination and damage due to collision.

This cassette is generally used for multiple X-ray imaging. Therefore, for example, when it is used for an infectious disease patient such as MRSA and reused without being disinfected, there is a risk that nosocomial infection may occur due to pathogenic bacteria attached to the cassette.
Therefore, as a conventional technique for preventing hospital-acquired infection due to a cassette, for example, a cassette cover described in Patent Document 1 is known. The cassette cover is a rectangular parallelepiped bag, and an opening formed at one end in the longitudinal direction can be opened and closed by a lid formed integrally with an upper surface material of the bag.

  However, when the cassette cover of Patent Document 1 is used, when opening the lid, the cassette cover is grasped with one hand and the lid is held with the other hand, so both hands have to be used. Therefore, the bag packing work is troublesome. Moreover, during the opening operation, the cassette is placed on the table, or when the table is not nearby, the cassette is placed aside, or the cassette is leaned against the wall for a short time. As a result, there is a possibility that bacteria such as a table and clothes may newly adhere to the surface of the sterilized cassette.

Accordingly, as a result of earnest research, the inventor produced a cassette storage bag from a synthetic resin sheet containing an antistatic agent, and held the cassette storage bag in an inclined state with the front sheet portion having the bag mouth facing downward. It has been found that the bag mouth opens by its own weight due to the weight of the front sheet portion of the storage bag. In addition, when the cassette is inserted into the bag mouth, it has been found that if the cassette insertion guide member is used, the cassette can be easily and reliably inserted into the bag opening opened by its own weight, and the present invention has been completed.
According to the present invention, the cassette storage bag can be held in its own weight opening state, and the cassette can be easily and reliably inserted into the cassette storage bag with one hand, thereby making contact with the external environment during cassette transportation. An object of the present invention is to provide an opening holder for a cassette storage bag that can prevent bacteria from adhering to the cassette.

  According to the first aspect of the present invention, there is provided an internal space for storing a large number of cassette storage bags for bagging X-ray imaging cassettes, and a plurality of the cassette storage bags formed on the front side and communicated with the internal space. A machine body having an entrance and exit, suspension means for suspending the plurality of cassette storage bags in an overlaid state in the internal space, and the one disposed most on the front side among the multiple cassette storage bags in the overlaid state An opening holding machine for a cassette storage bag provided with a cassette insertion guide member for guiding the cassette at a bag mouth, wherein the plurality of cassette storage bags are composed of a single synthetic resin sheet containing an antistatic agent. Fusing both sides of the front sheet portion formed by folding back to the rear sheet portion whose upper end portion protrudes from the upper edge of the front sheet portion, and a plurality of latches on the upper end portion of the rear sheet portion Hole A rectangular bag formed in a spaced manner in the direction, and the suspension means is disposed in the internal space of the machine body and can be inserted into a plurality of retaining holes of the multiple cassette storage bags, A plurality of spaced latching rods having stoppers for preventing a drop of the plurality of cassette storage bags, and a plurality of the latching rods, a horizontal posture with front ends facing forward or an upward inclined posture with front ends facing upward The cassette storage bag disposed at the most front side by the dead weight of the front sheet portion from the bag latching position for latching the large number of cassette storage bags to the downward inclined posture with the front end facing downward. A rotating structure that can be manually rotated about a horizontal rotation axis to a cassette bagging position where the bag mouth of the bag is opened, and a plurality of hanging rods are slidably provided, and the plurality of hanging The stopper rod is moved from the bag latching position to the cassette. A bag extruding member that, when rotated to the bag filling position, pushes the plurality of cassette storage bags hooked to the plurality of hooking rods against the stopper portion from behind by a downward slide by its own weight; The cassette insertion guide member guides the cassette to a bag mouth of the cassette storage bag arranged on the most front side when reaching the cassette bag filling position. It is an opening holder for a cassette storage bag provided with a bag support plate that supports lower portions of the large number of cassette storage bags inclined downward at the filling position.

The cassette is a rectangular panel case for storing an X-ray storage medium such as an X-ray film, an imaging plate, and an X-ray flat panel detector used at the time of X-ray imaging in the medical field. Typical dimensions of the cassette include 460 mm long × 384 mm wide × 15 mm thick.
As a material of the synthetic resin sheet (film) for the cassette storage bag, for example, polyvinyl chloride, polyethylene terephthalate, polypropylene or the like can be employed. Examples of the size of the cassette storage bag include a length of 590 mm, a width of 450 mm, and a thickness of 0.03 mm.
As the antistatic agent, for example, a surfactant, polyethylene oxide and the like can be employed. The antistatic agent may be coated on the front surface (back surface) of the synthetic resin sheet or may be kneaded into the synthetic resin material at the time of producing the sheet.
The number of cassette storage bags used is arbitrary as long as it is two or more. Of course, even one sheet can be used.

The airframe is a casing having an internal space and having openings such as doorways formed in predetermined wall plates.
As the material of the airframe, for example, various metals such as iron, stainless steel, and aluminum alloy, various synthetic resins such as polyethylene terephthalate, polyvinyl chloride, and polycarbonate can be employed.
The external shape of the aircraft is arbitrary. An example is a rectangular parallelepiped.
The doorway is formed on the front side (front plate) of the machine body, and its shape and opening size are arbitrary as long as the cassette storage bag can be taken in and out. In addition to the entrance / exit, in the case of a machine body that is a rectangular parallelepiped casing, for example, the outlet of the cassette storage bag packed with the cassette may be formed on one side plate or both side plates.
The upper plate of the machine body may be a lid body that can be opened and closed (rotated) around a horizontal lid rotation shaft so that a plurality of cassette storage bags can be easily latched on each latch rod.

The structure of the suspending means is arbitrary as long as it has at least a plurality of retaining rods, a rotating structure, and a bag pushing member.
Various metals, various synthetic resins, and the like can be used as the material for the retaining rod.
As the cross-sectional shape of the retaining rod, a circular plate shape, an elliptical shape, a triangular shape, a quadrangular shape, a polygonal shape of a pentagon or more, and a strip shape can be adopted.
The number of hooks used is two, three or more. In addition, in the case of a strip-shaped hooking rod, one may be sufficient.
As the stopper, for example, the tip of the hook is simply bent upward, the cap can be attached to and detached from the hook of the hook, and has a diameter larger than the hook of the cassette storage bag, the tip of the hook A split pin (holding pin) that can be attached to and detached from the part can be employed.

  The structure of the rotating structure is arbitrary as long as each latching bar can be rotated synchronously between the bag latching position and the cassette bagging position around the horizontal rotation axis. For example, each latch bar can be rotated synchronously by connecting the base of each latch bar to a horizontal rotation shaft. In addition, the rotating structure is provided with a manual rotating lock structure that can fix each latching rod that has reached the bag latching position and that can fix each latching rod that has reached the cassette bagging position. Is preferable.

As the rotation lock structure, for example, a shift lever type can be adopted. This is formed on the shift lever having the base connected to one end of the horizontal rotation shaft and the part of the wall plate of the fuselage where the horizontal rotation shaft is pivotally supported. And a two-stage shift groove having a pair of branch grooves that can be respectively hooked at the cassette bagging position.
The posture of each latching rod at the bag latching position may be a horizontal posture in which the axis of the latching rod is horizontal or an upward inclined posture in which the axis is inclined upward. The upward inclination angle with respect to the horizontal imaginary line of each retaining bar is preferably 5 ° to 30 ° so that the cassette storage bag can be easily hooked on each retaining bar.
Although the downward inclination angle with respect to the horizontal imaginary line of each latching bar is arbitrary at the cassette bag packing position, it is 20 ° to 45 ° (the inclination angle with respect to the vertical surface of the upper portion of the cassette storage bag is also 20 (° to 45 °) is preferable. If the angle is less than 20 °, the opening of the weight of the cassette storage bag tends to be insufficient. If it exceeds 45 °, it is difficult to insert the cassette into the cassette storage bag. A more preferable downward inclination angle of each retaining rod is 30 ° to 40 °. If it is this range, the bag mouth of a cassette storage bag can fully be opened, and it is easy to insert a cassette into a bag mouth also from an inclination angle.

As a raw material of the bag extrusion member, for example, various metals such as iron, stainless steel, brass, various synthetic resins such as polyethylene, polypropylene, polycarbonate, and various ceramics can be employed.
The bag extruding member is preferably a thick metal member in order to obtain a weight capable of pressing a plurality of cassette storage bags against the stopper portion. Although the length of the bag extruding member (the length in the width direction of the fuselage) is arbitrary, it is less likely to cause wrinkles due to the downward inclination of the cassette storage bag, and the same as the width of the cassette storage bag, and This is preferable because the opening width of the bag mouth at the time of opening can be maximized.
The bag pushing member is formed with a plurality of spaced apart slide holes through which the retaining rods are slidably inserted.

As the cassette insertion guide member, it is possible to employ, for example, a cylindrical body having a cassette discharge port formed at the lower end thereof opposed to the bag opening of the cassette storage bag at the cassette bag filling position. In addition, a chute plate or the like whose tip is directed to the bag mouth of the cassette bag at the cassette bag filling position can be employed.
As a material for the cassette insertion guide member, various metals, various synthetic resins, and the like can be used.
The cassette insertion guide member may be formed integrally with the machine body or may be formed separately from the machine body.
The formation position of the cassette insertion guide member is, for example, the upper part of the machine body.

As the bag support plate, various metal plates made of, for example, iron, stainless steel, brass, aluminum alloy, and various synthetic resin plates such as polyethylene, polyvinyl chloride, polypropylene, polyethylene terephthalate, and polycarbonate can be employed.
The bag support plate supports at most the lower half of the cassette storage bag. Of course, if there is no hindrance to opening the dead weight of the bag mouth, for example, a bag region of about two thirds from the lower side of the cassette storage bag may be supported.
The bag support plate may be elastically connected to the lower part of the machine body using a spring material in order to alleviate the impact at the time of the collision of the cassette that has been torn off from each of the retaining rods and dropped after packing.

  According to the first aspect of the present invention, the pivoting structure is manually operated, and each latching bar at the bag latching position where the plurality of cassette storage bags are latched is centered on the horizontal pivoting axis. Turn downward to the cassette bagging position. As a result, the bag pushing member slides downward with its own weight on each retaining rod, and presses the upper end portions of the plurality of cassette storage bags against the stopper portion from behind. As a result, the cassette storage bag is held in an inclined state in which the front sheet portion having the bag mouth is directed downward and each lower portion is supported by the bag support plate. At this time, the bag mouth opens by its own weight due to the weight of the front sheet portion of the cassette storage bag. In this state, the cassette is inserted into the bag mouth using the cassette insertion guide member. Accordingly, the cassette can be stored in the cassette storage bag with one hand simply and reliably. Moreover, it is possible to prevent bacteria from adhering to the cassette due to contact with the external environment during cassette transportation.

This is a rectangular bag obtained by fusing both side edges of the front sheet part 26 and the rear sheet part 27 whose upper end part protrudes from the upper edge of the front sheet part 26. In addition, at the upper end portion of the rear sheet portion 27, three hooking holes 28 are formed apart from each other at both ends in the bag width direction and at an intermediate portion thereof. Further, by coating the front and back surfaces of the polyvinyl chloride sheet with the surfactant, it is possible to prevent the front sheet portion 26 from being in close contact with the rear sheet portion 27 due to the action of static electricity.

  The cassette storage bag 12 has a length (length) of 590 mm, a width (width) of 450 mm, and a thickness of 15 mm. Further, the vertical length of the upper end portion of the rear sheet portion 27 is 110 mm. Therefore, the bag mouth 12 a is formed 110 mm below the upper side of the cassette storage bag 12. Further, in the upper side of the upper end portion of the rear sheet portion 27, each latching bag 12 after the cassette has been inserted is placed at a position facing each latching hole 28 so that the cassette storage bag 12 can be easily torn off from each latch rod 30. A slit extending to the vicinity of the hole 28 is formed.

  As shown in FIGS. 2 to 4, the suspending means 14 has a stopper portion 29 for preventing the cassette storage bag 12 from falling at the tip, and is long and spaced apart in the width direction while maintaining a parallel state. Three retaining rods 30, these retaining rods 30, a bag retaining position P <b> 1 where a plurality of cassette storage bags 12 are latched, and a tip about 35 ° (a cassette storage bag based on a vertical plane) The range of the cassette bag filling position P2 in which the bag mouth 12a of the cassette storage bag 12 is opened by the dead weight of the front sheet portion 26 by setting the downward inclination posture downward by about 35 °). The pivot structure 32 that is manually rotated about the horizontal pivot shaft 31 and the three latch bars 30 are slidably provided, and each latch bar 30 is inserted into the cassette from the bag latch position P1. When it was turned to the bagging position P2, it was hooked on the three hooks 30. A plurality of cassette storage bags 12 are provided with a bag pushing member 33 that presses against the stopper portion 29 from behind by a downward slide by its own weight.

  The three retaining rods 30 are accommodated in the upper part of the internal space a of the body 13. The stopper portions 29 that are inclined upward by 30 ° to 60 ° (here, about 45 °) with respect to the axis when they are horizontally arranged are integrally formed with the same material as the retaining rod 30. Is formed. Moreover, each latching bar 30 is formed with a recess 30a at the top of the root portion (FIG. 4). When the lid plate 22 is closed, the front end portion of the short stopper plate 34 projecting from the back surface of the front end portion of the lid plate 22 is fitted into the recess 30a, and the cassette storage bag 12 from each stopper portion 29 is fitted. Prevents the upper end of the detachment from falling off. Moreover, each latching bar 30 is comprised so that each front-end | tip may take the upward inclination attitude | position which turned up 5 to 15 degrees (here about 10 degrees) in the bag latching position P1.

  The rotating structure 32 has the horizontal rotating shaft 31 horizontally slidable in the axial direction adjacent to the lid rotating shaft 21 between the rear corners of the upper ends of the side plates 17. Have. The three retaining rods 30 are fixed at their original portions to both ends of the horizontal rotation shaft 31 and the intermediate portion in the length direction. One end portion of the horizontal rotation shaft 31 extends outward from one side plate 17, and a base portion of a long operation lever 35 extending forward is fixed to a part of the outer peripheral surface of the extended portion. doing. Note that both ends of the horizontal rotation shaft 31 are provided with a retaining process by increasing the diameter. An upper latch pin 36 and a lower latch pin 37 that is longer than the upper latch pin 36 are provided on the outer surface of the intermediate portion in the width direction among the upper ends of the one side plate 17 so as to be spaced apart from each other in the vertical direction. doing. The rotating structure 32 includes the horizontal rotating shaft 31, the operation lever 35, the upper latching pin 36, and the lower latching pin 37.

  The bag extruding member 33 is made of a thick stainless steel plate whose length is the same as the width of the cassette storage bag 12, and the sliding holes of the corresponding retaining rods 30 are provided at both end portions and intermediate portions in the length direction. 33a is formed through the front and back surfaces, respectively. Further, between the both ends of the bag pushing member 33 and the both ends of the horizontal rotation shaft 31, two pop-out prevention wires 38 having substantially the same length as the length of the retaining rod 30 excluding the stopper portion 29 are provided. It is bridged. As a result, the bag extruding member 33 is prevented from coming off from the retaining rods 30.

  The cassette insertion guide member 15 extends horizontally from the cassette insertion port 39 formed at the distal end portion of the lid plate 22 over substantially the entire length in the width direction and forward from the distal end portion of the lid plate 22 in the closed posture. And a short horizontal guide plate piece 40 that guides the cassette 11 from the horizontal direction toward the cassette insertion port 39, and a cassette port 12a of the cassette storage bag 12 in which the cassette 11 inserted into the cassette insertion port 39 is opened by its own weight. And a short downwardly inclined guide plate piece 41 for guiding to the side.

Next, with reference to FIGS. 1-4, the usage method of the opening holder 10 which concerns on Example 1 of this invention is demonstrated.
When the opening holder 10 is used, first, as shown in FIG. 2, the cover plate 22 is opened, and in this state, the operation lever 35 is rotated upward to be hooked on the upper latch pin 36. Thereby, the three latching bars 30 are arranged at the bag latching position P1 inclined upward by 10 °. In this state, while pushing back the bag pushing member 33 back along the outer peripheral surface of each latching bar 30, the plurality of cassette storage bags 12 are stacked in the stacked state through the respective latching holes 28. 30 (FIG. 2). At that time, lower portions of the plurality of cassette storage bags 12 are supported by the bag support plate 24. At this time, the cassette storage bag 12 is inclined downward by θ1 (about 15 °) with respect to the vertical line. For this reason, the bag mouth 12a of the cassette storage bag 12 is slightly opened by its own weight, but an opening width d of 50 mm or more (preferably 70 to 150 mm) necessary for reliably and smoothly inserting the cassette 11 into the bag mouth 12a is secured. hard. The opening width d is the width of the bag mouth at the middle portion in the length direction of the bag mouth 12a where the width of the opening (the length in the bag thickness direction) is maximum.

Thereafter, the lid plate 22 is rotated around the lid rotation shaft 21 to close the lid. Thereby, the recessed part 30a near the front-end | tip part of each latching bar 30 fits in the front-end | tip part of the short width | variety stopper plate piece 34 protrudingly provided by the back surface of the front-end | tip part of the cover board 22 (FIG. 4). Next, the operation lever 35 is grasped, the horizontal rotation shaft 31 is pulled out by a predetermined length in the axial direction, and the hand is released from the operation lever 35 in this state. As a result, the three latch bars 30 are approximately 35 until the tip of the operation lever 35 collides with the lower latch pin 37 and stops at the weight of the plurality of cassette storage bags 12 and the bag push-out member 33. It turns downward at a stroke.
Due to the impact at that time, the bag extruding member 33 slides downward on each retaining rod 30 by its own weight, and the upper end portions of the plurality of cassette storage bags 12 are stopper plates that are hooked by the stopper portions 29, actually, the recess portions 30a. Press against the piece 34 from behind. As a result, the cassette storage bag 12 is held in an inclined state at an angle θ (about 35 °) in which the front sheet portion 26 having the bag mouth 12a is directed downward and each lower portion is supported by the bag support plate 24. At this time, due to the weight of the front sheet portion 26 of the cassette storage bag 12, the bag mouth 12a opens its own weight by the opening width d.

  Next, holding this state, the lower surface of the tip of the cassette 11 grasped with one hand is pressed against the horizontal guide plate piece 40, and the cassette 11 is pushed into the cassette insertion port 39 as it is. Immediately thereafter, the tip of the cassette 11 collides with the downwardly inclined guide plate piece 41, and the direction in which the cassette 11 proceeds is automatically changed from the horizontal direction to the obliquely downward direction. As a result, if the cassette 11 is further pushed in, the cassette 11 is guided toward the bag opening 12a of the cassette storage bag 12 whose weight is opened by the opening width d. Thus, the cassette 11 can be stored (packed) in the cassette storage bag 12 with one hand easily and reliably. Moreover, since the cassette 11 is packed in the cassette storage bag 12 in this way, it is possible to prevent bacteria from adhering to the cassette 11 due to contact with the external environment during cassette transport.

  In addition, as shown in FIG. 5, it replaced with the bag extrusion member 33, thickened further from the thing of Example 1 (thickness 30-80 mm, here 60 mm), and the front surface from the both ends of a length direction You may employ | adopt the bag extrusion member 33A which gave the concave surface process (minimum width 5-20mm, here 10mm) which becomes thin thinly toward an intermediate part. If comprised in this way, inclination angle (theta) (about 35 degrees) of the said cassette storage bag 12 on the basis of a perpendicular line is made into inclination angle (theta) 2 (15 degrees-25 degrees, here about 20) smaller than the case of Example 1. )), The opening width d required for smooth insertion of the cassette 11 can be secured. As a result, the length (thickness) of the airframe 13 in the front-rear direction is shortened, and the airframe 13 can be made compact.

In FIG. 5, reference numeral 42 denotes a fixed hinge plate 43 fixed to the back surface of the intermediate portion in the length direction (the width direction of the machine body 13) of the bag push-out member 33 </ b> A, and the upper end portions of the plurality of cassette storage bags 12. Among these, it is a hinge-type bag latch hook that presses the intermediate portion in the width direction (width direction of the machine body 13) against the surface of the intermediate portion (thin wall portion) in the length direction of the bag push-out member 33A. Among the bag hooks 42, the downward L-shaped pivoting side hinge plate 44 is in contact with the second hooking rod 30 at an intermediate portion in the length direction of the lower side portion of the front plate piece 45. A bifurcated portion 45a is formed to prevent this. Thus, since the bifurcated structure is adopted as the bag latching hook 42, the upper ends of the plurality of cassette storage bags 12 can be pressed against the front surface (concave surface 33b) of the bag pushing member 33A over the entire length thereof. Thereby, the opening width d required for the smooth insertion of the cassette 11 can be stably secured. Further, if the front plate 45 is elongated downward (up to the length of the upper end of the rear sheet portion 27 at the maximum), even if the number of cassette storage bags 12 is reduced, the bag is pushed into the concave surface 33b of the bag pushing member 33. The opening width d can be secured satisfactorily, leaving a bend along the line.
Further, in FIG. 5, reference numeral 24 </ b> A denotes a bag support plate that is curved in a concave shape opposite to the concave surface, corresponding to the concave surface of the bag push-out member 33 </ b> A. Thereby, the opening width d requested | required of the bag mouth 12a of the cassette storage bag 12 can be ensured still more easily.

  The present invention is a work efficiency in which a cassette containing various storage media (X-ray film, imaging plate, X-ray flat panel detector, etc.) used for medical X-ray imaging is packed in a cassette storage bag. And is useful as a preventable hospital-acquired infection caused by cassettes.
