Description

[Technical field]

[0001] This utility model belongs to the technical field of medical film storage, and in particular to an image diagnostic film storage device. [Background technology]

[0002] In the medical imaging field, imaging departments generate a large amount of diagnostic imaging films every day, including X-ray films, CT films, and MRI films. These films play a vital role in diagnosing diseases, tracking treatment progress, and even in medical research, so they need to be stored properly. There are many problems with conventional methods of storing diagnostic imaging films. For one thing, in many cases, simple filing cabinets or drawer-type storage boxes are used, with simple internal structures and spaces simply divided by partitions. This means that medical staff spend a lot of time searching for the film, reducing work efficiency. In emergencies, this can lead to delays in diagnosis. In addition, humidity is a major challenge in film storage. Most storage environments do not have dedicated dehumidification measures, and moisture in the air makes the film susceptible to mold and moisture, especially in humid areas and during the rainy season. This can result in damage to the film itself, loss of image information, and the disposal of valuable medical materials. Summary of the Invention

[0003] In order to solve the above problems, this utility model provides a film storage device for diagnostic imaging equipped with a circulating ventilation and drying mechanism. This device accelerates the air flow in the storage chamber to prevent localized humidity, assists drying with wind power, and continuously circulates the air in the storage chamber by extracting, dehumidifying, and reinjecting it, providing a dry environment for film storage. In addition, the use of flexible partitions makes it easy to store folders of different thicknesses and makes it easy to search for films.

[0004] In order to achieve the above functions, the present utility model adopts the following technical means. An image diagnostic film storage device is provided, which includes a cabinet body. A partition plate is provided inside the cabinet body, and a storage chamber is divided into two layers, an upper layer and an lower layer, by the partition plate. A door is rotatably attached to the front opening of the storage chamber, and a circulation ventilation drying mechanism and a storage tray are installed inside the storage chamber. The circulation ventilation drying mechanism is installed under the ceiling of the storage chamber, and the storage tray is slidably connected to the bottom surface of the storage chamber. The circulation ventilation drying mechanism includes an air blowing component, a bidirectional transmission component, and a dehumidification ventilation component, all of which are installed under the ceiling of the storage chamber. The air blowing component is connected to the bidirectional transmission component, and the bidirectional transmission component is connected to the dehumidification ventilation component.

[0005] Preferably, the dehumidifying ventilation component includes a piston cylinder and a dehumidifying box, and two sets of piston cylinders are provided with the vertical center line of the storage chamber as the axis of symmetry. Two dehumidifying boxes are arranged in each piston cylinder, and the dehumidifying boxes are respectively connected to both ends of the piston cylinder. An intake port is provided on the side wall of the dehumidifying box, and an exhaust port is provided on the bottom, and a check valve is respectively installed in the intake port and the exhaust port. Preferably, the bidirectional transmission component includes a gear and a rack, the gear is rotatably installed under the ceiling of the storage room, two sets of the rack are arranged opposite to the gear, the rack is slidably installed under the ceiling of the storage room and designed to mesh with the gear, and the end of each rack is fixedly connected to the push-pull rod of the piston cylinder. Preferably, the air blowing component includes a DC motor and a fan blade, the DC motor is fixed to the lower part of the ceiling of the storage room, the fan blade is attached to an output shaft of the DC motor, a transmission belt is attached to the output shaft of the DC motor, and the transmission belt is transmission-connected to the rotating shaft of the gear. Preferably, the storage tray has evenly spaced flexible dividers and a handle on an outer wall of the storage tray.

[0006] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The installation of the circulating ventilation and drying mechanism allows the air blowing component, bidirectional transmission component, and dehumidification ventilation component to work together, and the DC motor periodically rotates forward and backward to drive the fan blades. This accelerates the air flow in the storage room, prevents localized humidity, and uses wind power to assist drying. At the same time, the gears, racks, piston cylinders, and dehumidification boxes work together to continuously extract, dehumidify, and reinject air into the storage room. This controls the humidity to an appropriate range, providing an optimal environment for film storage. As a result, the service life of the film is extended and waste loss due to humidity is reduced. 2. The dehumidifying boxes installed on both sides of the piston cylinder are equipped with air inlets and exhaust ports, one side extracts moisture from the storage chamber, and the other side blows dry air. This stabilizes the air pressure in the storage chamber and realizes dynamic gas exchange, so that the problem of air pressure dropping due to simple air extraction and external moisture accelerating inflow can be avoided. This keeps the air pressure in the storage chamber stable at all times, and the dehumidification speed is greatly improved by the two-way synchronous ventilation process. 3. The flexible partitions installed in the storage tray allow folders of different thicknesses to be easily stored. By storing items neatly and separately, space utilization is improved, items can be easily retrieved, and search times are significantly reduced. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] The technical solutions of the present utility model are described below clearly and completely with reference to the drawings. Obviously, the described embodiments are only some of the embodiments of the present utility model, but not all of them. Based on the embodiments in the present utility model, all other embodiments obtained by those skilled in the art without creative ingenuity belong to the protection scope of the present utility model.

[0009] As shown in Figs. 1 to 6, the image diagnostic film storage device according to the present utility model includes a cabinet body 1. A partition plate 2 is provided inside the cabinet body 1, and a storage chamber 3 is divided into two layers, an upper layer and an lower layer, by the partition plate 2. A door 4 is rotatably attached to the front opening of the storage chamber 3, and a circulation ventilation drying mechanism 5 and a storage tray 6 are provided inside the storage chamber 3. The circulation ventilation drying mechanism 5 is provided under the ceiling of the storage chamber 3, and the storage tray 6 is slidably connected to the bottom surface of the storage chamber 3. The circulation ventilation drying mechanism 5 includes an air blowing component 51, a bidirectional transmission component 52, and a dehumidification ventilation component 53, all of which are provided under the ceiling of the storage chamber 3. The air blowing component 51 is connected to the bidirectional transmission component 52, and the bidirectional transmission component 52 is connected to the dehumidification ventilation component 53.

[0010] As shown in FIG. 3 to FIG. 5, the dehumidifying ventilation component 53 includes a piston cylinder 531 and a dehumidifying box 532. Two sets of the piston cylinders 531 are provided with the vertical center line of the storage chamber 3 as the axis of symmetry. A piston plate 5311 is movably installed inside the piston cylinder 531, and a push-pull rod 5312 is fixedly connected to the side of the piston plate 5311. An end of the push-pull rod 5312 extends from the piston plate 5311 and is movable through the piston cylinder 531. Two dehumidifying boxes 532 are arranged in each piston cylinder 531, and the dehumidifying boxes 532 are connected to both ends of the piston cylinder 531, respectively. The dehumidifying boxes 532 are filled with calcium chloride desiccant, and the dehumidifying boxes 532 are replaceable. An intake port 5321 is provided on the side wall of the dehumidifying box 532, and an exhaust port 5322 is provided on the bottom surface, and check valves 5323 are provided in the intake port 5321 and the exhaust port 5322, respectively. The check valve 5323 is for ensuring one-way transport of airflow. The bidirectional transmission component 52 includes a gear 521 and a rack 522. The gear 521 is rotatably installed under the ceiling of the storage room 3, and two sets of racks 522 are arranged opposite to the gear 521. The racks 522 are slidably installed under the ceiling of the storage room 3 and are designed to mesh with the gears 521. The ends of each rack 522 are fixedly connected to the push-pull rod 5312 of the piston cylinder 531. The gear 521 can drive the racks 522 to move in opposite directions, causing the push-pull rod 5312 to reciprocate. This causes the piston plate 5311 to reciprocate within the piston cylinder 531, and alternately compresses the gas on both sides of the piston plate 5311 in the cylinder. The blowing component 51 includes a DC motor 511 and a fan blade 512. The DC motor 511 is fixed to the lower part of the ceiling of the storage room 3, and the fan blades 512 are attached to the output shaft of the DC motor 511. A transmission belt 513 is attached to the output shaft of the DC motor 511, and the transmission belt 513 is synchronously connected to the rotating shaft of the gear 521.The DC motor 511 can rotate forward and backward periodically, and the distance that the gear 521 moves the rack 522 during one operation is controlled so that the rack 522 does not come off the gear 521. The rack 522 is designed to always maintain a state of meshing with the gear 521 when the DC motor 511 rotates forward and backward. The DC motor 511 drives the fan blade 512 to rotate, accelerating the air flow in the storage room 3 and fan-drying the inside of the storage room 3. In addition, the gear 521 rotates via the transmission belt 513, and the gear 521 drives the rack 522 to move in the opposite directions. At this time, the rack 522 reciprocates the push-pull rod 5312, and the push-pull rod 5312 drives the piston plate 5311 to perform piston movement in the piston cylinder 531. On one side of the piston cylinder 531, air in the storage chamber 3 is drawn in through the air inlet 5321 of the dehumidifying box 532, dehumidified by the desiccant, and then sent into the piston cylinder 531. On the other side, the dehumidified air is exhausted back into the storage chamber 3 through the air outlet 5322. By repeating this process, the air in the storage chamber 3 is continuously dried, ensuring a dry storage environment for the diagnostic imaging film.

[0011] As shown in Figure 6, flexible dividers 61 are evenly arranged on the storage tray 6, and handles 62 are provided on the outer walls of the storage tray 6. The flexible dividers 61 are convenient for dividing and storing film storage folders 63. The outside of the folders 63 are labeled, making it easy to search for films. In addition, the flexible dividers 61 are shape-changeable, making them suitable for storing folders of different thicknesses. When in use, the medical staff classifies the films to be stored based on the patient information, examination date, etc., and stores them in the labeled folders 63. They grasp the handle 62 of the storage tray 6, pull out the storage tray 6, and store the folders 63 in the designated position, then return the storage tray 6 to the storage room 3 and close the door 4.

[0012] The structure of FIG. 3 and FIG. 4 will be taken as an example. After the power supply of the device is connected, the DC motor 511 starts to operate according to a preset timer program, and rotates forward and backward repeatedly. When the DC motor 511 rotates clockwise, the output shaft drives the fan blade 512 to rotate. At this time, the fan blade 512 quickly stirs the air in the storage room 3, promotes the flow of air, and moves the humid air toward the dehumidifying ventilation component 53. At the same time, the power is transmitted to the gear 521 through the transmission belt 513, and the gear 521 rotates, so that the two meshed sets of racks 522 move in opposite directions. When the rack 522 connected to the left piston cylinder 531 moves leftward, the volume of the right chamber of the piston cylinder 531 increases and the pressure decreases. In this state, the air in the storage room 3 is sucked in through the intake port 5321 of the dehumidifying box 532 on the right side of the piston cylinder 531 due to the action of the check valve 5323. When air passes through the dehumidifying box 532, moisture is adsorbed by the desiccant inside, and the dried air is sent to the right chamber of the piston cylinder 531. Meanwhile, the air in the left chamber of the piston cylinder 531 is discharged into the storage chamber 3 through the exhaust port 5322 of the left dehumidifying box 532. When the rack 522 connected to the right piston cylinder 531 moves rightward, the right chamber of the piston cylinder 531 is compressed, and the internal pressure increases. At this time, the dried air is discharged again into the storage chamber 3 through the exhaust port 5322 of the dehumidifying box 532 on the right side of the piston cylinder 531 under the control of the check valve 5323. When the DC motor 511 rotates counterclockwise, the above process is repeated in the opposite direction, and the operating states of the left and right piston cylinders 531 are switched. In this way, the air in the receiving chamber 3 is continuously dried.

[0013] Although the present utility model and its implementation modes have been described above, such description is not restrictive, and what is shown in the drawings is merely one of the implementation modes of the present utility model, and the actual application is not limited thereto. In other words, any structural aspects and embodiments similar to the technical means designed by a person skilled in the art based on the suggestions, without departing from the purpose of the creation of the present utility model, and without any originality, should all fall within the protection scope of the present utility model.
