Description

Application for application of Article 30, Paragraph 2 of the Patent Act has been filed. The applicant sold the product of the claimed invention to LIO Co., Ltd. on May 12, 2020.

The present invention relates to an oxygen capsule suitable for animals such as racehorses and pets.

Oxygen capsules have been known that are configured to increase the internal pressure higher than atmospheric pressure to increase the amount of oxygen that dissolves into the blood of the person being cared for (humans, horses, pets, etc.). As such oxygen capsules, in addition to those for one person (see, for example, Patent Document 1), there are also those that can be used by multiple people at the same time (see, for example, Patent Document 2).

In a high-concentration oxygen environment with increased atmospheric pressure, the absorption of oxygen into the user's body is promoted, which is said to have effects such as recovering from fatigue and promoting recovery from injury. Therefore, oxygen capsules are widely used by athletes and the like. Additionally, in recent years, oxygen capsules have been developed for animals such as racehorses and pets. For example, there have been reports of racehorses using oxygen capsules designed for horses to help them recover quickly from injuries.

The oxygen capsule 10 has an operation unit 80 that receives operations related to increasing the pressure inside the capsule body 10A. Hereinafter, the inside of the capsule body 10A will also be referred to as "capsule interior."

As illustrated in FIG. 2, the oxygen capsule 10 includes a pressurizing unit 90 that supplies air to the inside of the capsule, and an oxygen supply unit 95 that supplies oxygen to the inside of the capsule. The pressurizing unit 90 includes, for example, a plurality of pressurizing means 91 including an air compressor that generates compressed air. The plurality of pressurizing means 91 are controlled by the operating unit 80 and feed compressed air so that the pressure inside the capsule becomes a set pressure. The pressurizing unit 90 is for increasing the arterial blood oxygen partial pressure (PaO2) of the care subject by increasing the pressure inside the capsule, thereby increasing the amount of oxygen dissolved in the care subject's blood. The pressurizing unit 90 may be configured such that one pressurizing means 91 centrally controls the operations of all the pressurizing means 91 in accordance with a command from the operating unit 80. Although FIG. 2 shows an example in which each pressure means 91 is placed on the lower mounting portion 24, the arrangement is not limited to this, and the arrangement of each pressure means 91 can be changed as appropriate. The number of pressurizing means 91 can also be changed as appropriate.

The oxygen supply unit 95 is composed of a plurality of oxygen supply means 96 including, for example, an oxygen concentrator. Oxygen concentrators have the function of adsorbing nitrogen in air components to generate air with a high oxygen concentration (for example, air with an oxygen concentration of 50% or more), and also have the function of generating air with a high oxygen concentration (air with a high concentration of oxygen). ) is supplied to the inside of the capsule. The oxygen supply unit 95 is for causing the care subject inside the capsule to inhale high concentration oxygen to further increase the blood oxygen concentration of the care subject. Therefore, it is preferable to provide a nozzle or the like arranged inside the capsule so that highly concentrated oxygen is discharged toward the care target. Each oxygen supply means 96 can adjust the oxygen concentration of the air it discharges, and is activated when the power is turned on. Although FIG. 2 shows an example in which each oxygen supply means 96 is placed on the installation surface of the oxygen capsule 10, the arrangement is not limited to this, and the arrangement of each oxygen supply means 96 can be changed as appropriate. The number of each oxygen supply means 96 can also be changed as appropriate. Note that the oxygen capsule 10 may be configured without the oxygen supply unit 95.

A plurality of first holes _h1 are formed in the upper region of the main body part 20 both at the front (see FIG. 1) and at the rear (see FIG. 2). Each figure shows an example in which a plurality of first holes _h1 are lined up in a row. A stabilizing valve Va consisting of, for example, a relief valve is provided in the first hole _h1 . The stabilizing valve Va releases air to the outside to release the pressure when the inside of the capsule reaches a set pressure, thereby stabilizing the internal pressure. The set pressure is set to, for example, 1.3 atmospheres, and can be changed as appropriate.

A plurality of second holes h2 are formed in the lower region of the main body 20, both at the front (see FIG. 1) and at the rear (see FIG. ₂ ). In the example of FIG. 1, a plurality of second holes _h2 are formed in the front of the main body part 20 in an area on the first door 30 side and an area on the second door 40 side with the entrance/exit hole 20h in between. ing. A pressurizing unit 90 or an oxygen supply unit 95 is connected to the second hole _h2 .

More specifically, air pipes (not shown) extending from the pressurizing means 91 are connected to some of the second holes _h2 . The air pipe is made of, for example, an air hose, and supplies the air discharged from the pressurizing means 91 into the inside of the capsule. Furthermore, oxygen pipes (not shown) extending from the oxygen supply means 96 are connected to some of the second holes _h2 . The oxygen pipe is made of, for example, an air hose, and supplies high concentration oxygen discharged from the oxygen supply means 96 to the inside of the capsule.

In the example of FIGS. 1 and 2, several second holes h2 surrounded by broken line rectangles are connected to the pressurizing means 91 via air pipes, and several second holes _h2 surrounded by broken line rounded rectangles are connected to the pressurizing means 91 through air pipes. The second hole _h2 is connected to the oxygen supply means 96 via an oxygen pipe, and the other second holes _h2 are reserved as a reserve. A plug is attached to the spare second hole _h2 to prevent air leakage.

The number of second holes _h2 , the number of pressurizing means 91, and the number of oxygen supply means 96 can be arbitrarily set and changed as appropriate. Furthermore, the position of the second hole _h2 that connects the pressurizing means 91 and the oxygen supply means 96 can also be arbitrarily set and changed as appropriate. However, it is preferable that the oxygen supply means 96 be connected to the second hole _h2 on the side where the animal's face is placed, that is, on the second door 40 side of the main body part 20. Oxygen is absorbed through the animal's skin, but primarily through the animal's nose and mouth. That is, by connecting the oxygen supply means 96 to the second hole _h2 on the second door 40 side, which is the exit for the animal, absorption of oxygen by the animal can be promoted.

Further, the main body portion 20 is formed with a plurality of combinations of third holes h ₃ and fourth holes h ₄ that are arranged adjacent to each other. The third hole _h3 is provided with a pressure reducing valve Vb that can be operated from the inside of the main body 20, and the fourth hole _h4 is provided with a pressure reducing valve Vc that can be operated from the outside of the main body 20.

The open state and fastened state of the auxiliary fastening means 12 are defined similarly to the open state and fastened state of the main fastening means 11.

As the detection means 11s, various sensors such as a pressure sensor, an optical sensor, an infrared sensor, a magnetic sensor, etc. can be employed. The detection means 11s illustrated in FIG. 7 is turned on when the main fastening means 11 is open, that is, when the shaft portion 11c is out of the notch, and when the main fastening means 11 is closed, that is, the shaft portion 11c. is configured and arranged so that it is turned off when it is inserted into the notch. In addition, in FIG. 7, in order to illustrate 11 s of detection means, some fixing|fixed parts 11a are abbreviate|omitted. The detection means 11s transmits detection data indicating whether or not the main fastening means 11 is open to the opening/closing processing device 70. The detection means 11s may transmit detection data to the opening/closing processing device 70, for example, at the timing when the open/close state of the main fastening means 11 is switched.

The auxiliary fastening means 12 reinforces the force exerted by the main fastening means 11 to press each door toward the main body 20 side, and disperses the force directed toward the outside of each door. The auxiliary fastening means 12 has a fixed part 12a, a rotation support part 12b, a shaft part 12c, and an assist handle 12d. The auxiliary fastening means 12 is arranged between the two main fastening means 11, for example. In this embodiment, the detection means 11s is attached only to the main fastening means 11 and not to the auxiliary fastening means 12.

For example, if the specified data is in the first state, the drive processing means 72d receives an operation signal (hereinafter also referred to as an "open command") sent from the first opening/closing operation section 75A indicating that the second button 77b is pressed. ), the electric motor of the first drive mechanism section 50A is driven to open the first door 30. If the specified data is in the second state, the drive processing means 72d drives the electric motor of the second drive mechanism section 50B to open the second door 40 in response to the opening command transmitted from the second opening/closing operation section 75B. let The drive processing means 72d acquires information about the angle formed between the main body flange of the main body part 20 and the door flange of the door, for example, from an angle sensor (not shown) provided on the door.

Further, if the specified data is in the second state, the drive processing means 72d receives an operation signal (hereinafter also referred to as a "close command") transmitted from the first opening/closing operation section 75A indicating that the third button 77c is pressed. ), the electric motor of the first drive mechanism section 50A is driven to close the first door 30. If the specified data is in the second state, the drive processing means 72d drives the electric motor of the second drive mechanism section 50B to close the second door 40 in response to the closing command transmitted from the second opening/closing operation section 75B. let

The control unit 72 is composed of an arithmetic device such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit), and an opening/closing processing program 73p that cooperates with such arithmetic device to realize the various functions described above and below. Can be done. That is, the opening/closing processing program 73p is software for causing the computer to function as the information processing means 72a, the operation processing means 72b, the output processing means 72c, and the drive processing means 72d.

Next, an example of the functional configuration and specific configuration of the operating unit 80 will be described with reference to FIGS. 23 and 24. Note that, as shown in FIGS. 12 to 14, the oxygen capsule 10 of this embodiment is provided with an operation panel as shown in FIG. 24 not only on the outside of the oxygen capsule 10 but also on the inside. . Therefore, the user can perform operations such as setting a timer from inside and outside the oxygen capsule 10.

As shown in FIG. 23, the operating unit 80 includes a communication section 81, a management processing section 82, a storage section 83, an operation section 84, a display section 85, and a light emitting section 86. The communication unit 81 is an interface through which the management processing unit 82 communicates with external devices such as the pressurizing means 91 and the oxygen supplying means 96 by wire or wirelessly. The storage unit 83 stores various information in addition to the operating program of the management processing unit 82. The storage unit 83 is composed of RAM, ROM, flash memory, SSD, or the like. The operation unit 84 is composed of buttons and the like that accept various input operations.

The operation unit 84 outputs an operation signal indicating the content of the user's operation to the management processing unit 82. The display unit 85 is configured with a 7-segment liquid crystal display, a liquid crystal display (LCD), or the like. The operation section 84 and the display section 85 may be a touch panel configured by stacking them. In this case, the operation unit 84 detects the position touched by the user, and outputs information such as the detected position to the management processing unit 82. The light emitting section 86 is composed of, for example, an LED.

The management processing section 82 displays various information on the display section 85 and changes the light emitting state of the light emitting section 86 in response to an operation signal from the operation section 84 . Furthermore, the management processing section 82 operates at least one of the pressurizing means 91 and the oxygen supplying means 96 in response to an operation signal from the operation section 84 or at a preset timing. The management processing unit 82 can be configured by a calculation device such as a CPU or GPU, and software that cooperates with such a calculation device to realize the various functions described above and below.

The operating unit 80 illustrated in FIG. 24 has a power switch 84a, an Up button 84b, and a Down button 84c as the operation section 84. The operating unit 80 also includes a pressure display section 85a and a timer display section 85b as the display section 85. Further, the operating unit 80 includes a light emitting part 86a associated with the power switch 84a, and a light emitting part 86b indicating the on/off state of a predetermined operation mode. The predetermined operation mode may be a restriction mode in which certain operations are restricted.

When the power switch 84a is pressed while the power is off, the management processing section 82 causes the light emitting section 86a to emit light and displays the pressure inside the capsule on the pressure display section 85a, for example. The management processing unit 82 acquires pressure data to be displayed on the pressure display unit 85a from, for example, a pressure sensor (not shown) installed inside the capsule. When the Up button 84b is pressed, the management processing section 82 increases the set time of the timer display section 85b, and when the Down button 84c is pressed, the management processing section 82 decreases the set time of the timer display section 85b.

The management processing unit 82 operates the pressurizing means 91 so that the pressure inside the oxygen capsule 10 rises to the set pressure. The set pressure is set to 1.30 [ATA], for example, and can be changed as appropriate. In this embodiment, the management processing unit 82 operates the pressurizing means 91 when the power is turned on. Note that the management processing unit 82 may have a function of controlling the operation of the pressurizing means 91 in order to maintain the internal pressure of the oxygen capsule 10 at a set pressure.

Next, based on FIGS. 25 to 27 and with reference to each of FIGS. 1 to 24 as appropriate, we will explain how to use the oxygen capsule 10 according to the present embodiment, and how the door opening/closing process by the opening/closing processing device 70 will be explained. Explain by interweaving them. First, the process and operation for opening the first door 30 and allowing the horse H to enter the room will be described based on the flowchart of FIG. 25.

Before opening the first door 30, the user opens each fastening means on the first door 30 side. In the configuration of this embodiment, the user may open all the auxiliary fastening means 12 and then open all the main fastening means 11 (step S101).

When the first button 77a of the first opening/closing operation section 75A is pressed (step S102/Yes), the control section 72 of the opening/closing processing device 70 updates the specified data using the operation processing means 72b. As a result, the specified data becomes the first state (step S103). Note that although FIG. 25 shows an operation example of waiting until the first button 77a is pressed (step S102/No), if the specified data is already in the first state, the processing of steps S102 and S103 is performed. can be omitted.

Further, the control unit 72 uses the output processing means 72c to determine whether all the main fastening means 11 are in the open state, that is, whether the first open state data indicates a fully open state (step S104 ). In the present embodiment, if the first open state data indicates a fully open state (step S104/Yes), the output processing means 72c lights up the first light emitting section 78a of the first opening/closing operation section 75A (step S104/Yes). S105). On the other hand, if the first open state data does not indicate a fully open state (step S104/No), the output processing means 72c causes the first light emitting section 78a of the first opening/closing operation section 75A to blink (step S106).

When the second button 77b of the first opening/closing operation section 75A is pressed and an opening command is transmitted from the first opening/closing operation section 75A (Step S107/Yes), the control section 72 of the opening/closing processing device 70 starts driving. The processing means 72d operates the first drive mechanism section 50A so that the first door 30 opens. That is, the drive processing means 72d drives the electric motor of the first drive mechanism section 50A in the direction in which the first door 30 opens in response to the opening command from the first opening/closing operation section 75A. At this time, the output processing means 72c may cause the second light emitting section 78b of the first opening/closing operation section 75A to emit light (step S108).

The drive processing means 72d operates the first drive mechanism section when the second button 77b is pressed until the angle between the main body flange and the door flange 31 reaches the maximum opening angle (step S109/No). 50A is operated (step S107/Yes, step S108), and when the second button 77b is not pressed, the operation of the first drive mechanism section 50A is stopped (step S107/No). However, if the first open state data does not indicate a fully open state (step S104/No), the drive processing means 72d will control the first drive mechanism even if the second button 77b of the first opening/closing operation section 75A is pressed. The section 50A is not operated.

When the angle formed reaches the maximum opening angle (Step S109/Yes), the drive processing means 72d stops the operation of the first drive mechanism section 50A and prevents the first door 30 from opening any further outward (Step S110). ). Note that the output processing means 72c causes the second light emitting section 78b to emit light while the second button 77b is pressed until the angle formed between the main body flange and the door flange 31 reaches the maximum opening angle, When the second button 77b is not pressed, the second light emitting section 78b may be turned off. Further, the output processing means 72c may turn off the second light emitting section 78b in a state where the angle formed is the maximum opening angle.

After opening the first door 30 through the series of steps described above, the user places the slope 100 at the opening of the main body 20 on the first door 30 side, as shown in FIG. The user is allowed to enter the room (step S111). When horse H completes entering the room, the user usually presses the third button 77c of the first opening/closing operation section 75A.

When the third button 77c of the first opening/closing operation section 75A is pressed and a closing command is sent from the first opening/closing operation section 75A (Step S112/Yes), the control section 72 of the opening/closing processing device 70 starts driving. The first drive mechanism section 50A is operated by the processing means 72d so that the first door 30 is closed. That is, the drive processing means 72d drives the electric motor of the first drive mechanism section 50A in the direction in which the first door 30 closes in response to the closing command from the first opening/closing operation section 75A. At this time, the output processing means 72c may cause the third light emitting section 78c of the first opening/closing operation section 75A to emit light.

The drive processing means 72d operates the first drive mechanism section 50A while the third button 77c is pressed until the first door 30 enters the deceleration area (step S113/No). At this time, the drive processing means 72d drives the electric motor of the first drive mechanism section 50A at the normally set rotation speed (step S114). On the other hand, when the third button 77c is not pressed, the drive processing means 72d stops the operation of the first drive mechanism section 50A (step S112/No). The drive processing means 72d may be configured to determine whether or not the first door 30 has entered the deceleration area, using detection data from, for example, an angle sensor or a limit switch disposed on the door.

When the first door 30 enters the deceleration area (Step S113/Yes), the drive processing means 72d decelerates the electric motor of the first drive mechanism section 50A to a low rotation speed that is set lower than the normal rotation speed. drive. At this time, the output processing means 72c may cause the third light emitting section 78c to blink (step S115).

The drive processing means 72d drives the electric motor of the first drive mechanism section 50A at a low rotation speed while the third button 77c is pressed until the angle formed reaches the minimum opening angle (step S116/No). let When the angle formed reaches the minimum opening angle (step S116/Yes), the drive processing means 72d stops the electric motor of the first drive mechanism section 50A, and prevents the door flange 31 from approaching the first flange 21a any further ( Step S117). At this time, the output processing means 72c may turn off the third light emitting section 78c. However, the processing in steps S116 and S117 may be performed automatically using a limit switch or the like.

Then, the user sets each fastening means on the first door 30 side to a fastened state. In the configuration of this embodiment, the user may put all the main fastening means 11 into the fastened state and then put all the auxiliary fastening means 12 into the fastened state (step S118).

Next, the flow of operations centering on the opening/closing process of the door section 15 will be described based on the flowchart of FIG. 26. Here, explanation will be given assuming that the door portion 15 is in a closed state when guiding the horse H into the capsule. The user who has guided the horse H into the capsule as shown in FIG. 25 normally leaves the door 15 open and exits through the access hole 20h.

For example, the user rotates the inner lever 8b with respect to the locking mechanism part 8 in a fixed state as shown in FIGS. 18 and 19, and removes the engagement protrusion 8c from the receiving part 8e. As a result, the fixed state of the locking mechanism section 8 is released, and the state shown in FIGS. 16 and 17 is achieved (step S201). Next, the user grasps the inner handle 1d and pulls the door body 1 inward, for example. As a result, the door portion 15 changes from the closed state (see FIGS. 16 and 17) to the fully facing state (see FIGS. 14 and 15). That is, the door body 1 moves inward along the first rail 2a (step S202).

Next, the user moves the door body 1 along the second rail 3a by grasping the inner handle 1d, for example, and changes the door part 15 from the fully facing state as shown in FIG. 14 to the open state (see FIG. 12). Step S203). The user then exits from the entrance/exit hole 20h as shown in FIG. 9 (step S204).

Next, the user grips, for example, at least one of the inner handle 1d and the outer handle 1f from outside the oxygen capsule 10, pulls the door body 1 toward the entrance/exit hole 20h, and moves it along the second rail 3a. Finally, the user grasps the outer handle 1f and moves the door body 1 to the front of the entrance/exit hole 20h, so that the door part 15 is in the fully facing state (see FIG. 15) (step S205).

Next, the user grasps the outer handle 1f and pulls the door body 1 outward. As a result, the door portion 15 changes from the fully facing state (see FIGS. 14 and 15) to the closed state (see FIGS. 16 and 17). That is, the door body 1 moves outward along the first rail 2a (step S206). Next, the user rotates the outer lever 8a with respect to the lock mechanism section 8 in the released state as shown in FIGS. 16 and 17, and engages the engagement protrusion 8c with the receiving section 8e. As a result, the lock mechanism section 8 enters the locked state as shown in FIGS. 18 and 19 (step S207).

Then, by operating the operating unit 80 or the like, the user instructs to start increasing the pressure inside the capsule, start supplying high concentration oxygen to the inside of the capsule, and start a timer. The management processing unit 82 of the operating unit 80 starts controlling the pressurizing unit 90 in order to increase the pressure inside the capsule in response to the user's operation, etc., and causes the care target inside the capsule to inhale high concentration oxygen. A drive command is sent to the oxygen supply unit 95 accordingly. At this time, the management processing unit 82 starts counting the set time. When the user changes the set time, the management processing unit 82 resets the timer and starts measuring the time using the new set time (step S208).

By the way, the processing in steps S201 to S203 may be performed by another user outside. In this case, the user releases the locked state of the locking mechanism section 8 by rotating the outer lever 8a and removing the engagement protrusion 8c from the receiving section 8e (step S201). Next, the user pushes the door body 1 inward by, for example, grasping the outer handle 1f. Alternatively, the user places his hand on the surface of the door body 1 and pushes it inward. Thereby, the door body 1 moves inward along the first rail 2a (step S202). Next, the user moves the door body 1 along the second rail 3a by grasping the outer handle 1f, for example, and changes the door portion 15 from the fully facing state to the open state (step S203). However, each process shown in FIG. 26 may be performed by different users from inside and outside the oxygen capsule 10.

Next, the process and operation of opening the second door 40 and letting the horse H exit will be described based on the flowchart of FIG. 27. Although the second door 40 is the operation target here, the processing and operation for the second door 40 are substantially the same as the processing and operation for the first door 30, so the steps equivalent to each step in FIG. are given the same reference numerals, and duplicate explanations will be omitted.

The management processing unit 82 of the operating unit 80 waits until the set time related to the care of the horse H has elapsed (step S301/No). When the set time has elapsed (Step S301/Yes), the management processing unit 82 stops the operation of the pressurizing means 91 and the oxygen supply means 96, and reduces the pressure inside the capsule (Step S302). Here, the operating unit 80 may have a notification section including a speaker. In this case, the management processing section 82 may cause the notification section to output a sound or voice when the pressure inside the capsule becomes approximately the same as the pressure of the outside air. The management processing unit 82 may cause the notification unit to output sound or voice at the timing when the set time has elapsed.

When the user confirms that the pressure inside the capsule has decreased to a certain extent by visually checking the pressure display section 85a of the operating unit 80, etc., the user opens each fastening means on the second door 40 side (step S101). When the first button 77a of the second opening/closing operation section 75B is pressed (Step S102/Yes), the operation processing means 72b updates the specified data to set it in the second state (Step S103).

In this embodiment, if the second open state data indicates a fully open state (step S104/Yes), the output processing means 72c lights up the first light emitting section 78a of the second opening/closing operation section 75B (step S104/Yes). S105). On the other hand, if the second open state data does not indicate a fully open state (step S104/No), the output processing means 72c causes the first light emitting section 78a of the second opening/closing operation section 75B to blink (step S106). When the second button 77b of the second opening/closing operation section 75B is pressed and an opening command is transmitted from the second opening/closing operation section 75B (Step S107/Yes), the drive processing means 72d controls the second door 40 to open. The second drive mechanism section 50B is operated to open (step S108).

The drive processing means 72d operates the second drive mechanism section when the second button 77b is pressed until the angle formed between the main body flange and the door flange 41 reaches the maximum opening angle (step S109/No). 50B is activated (Step S107/Yes, Step S108), and when the second button 77b is not pressed, the operation of the second drive mechanism section 50B is stopped (Step S107/No). When the angle formed reaches the maximum opening angle (Step S109/Yes), the drive processing means 72d stops the operation of the second drive mechanism section 50B and prevents the second door 40 from opening any further outward (Step S110). ).

After the second door 40 is opened as shown in FIG. 20 through the above series of steps, the slope 100 is placed at the opening of the main body 20 on the second door 40 side, as shown in FIG. (step S303). When the horse H has finished leaving, for example, the user presses the third button 77c of the second opening/closing operation section 75B in preparation for the next use of the oxygen capsule 10.

When the third button 77c of the second opening/closing operation section 75B is pressed and a closing command is transmitted from the second opening/closing operation section 75B (Step S112/Yes), the drive processing means 72d controls the second door 40 to close. The second drive mechanism section 50B is operated so as to be closed. The drive processing means 72d operates the second drive mechanism section 50B while the third button 77c is pressed until the second door 40 enters the deceleration area (Step S113/No) (Step S114). On the other hand, when the third button 77c is not pressed, the drive processing means 72d stops the operation of the second drive mechanism section 50B (Step S112/No).

When the second door 40 enters the deceleration area (Step S113/Yes), the drive processing means 72d decelerates the electric motor of the second drive mechanism section 50B and drives it at a low rotation speed (Step S115). When the angle formed reaches the minimum opening angle (step S116/Yes), the drive processing means 72d stops the operation of the second drive mechanism section 50B and prevents the door flange 41 from approaching the second flange 21b any further ( Step S117). Then, the user sets each fastening means on the second door 40 side to a fastened state (step S118).

Note that although the operations have been explained based on the flowcharts of FIGS. 25 to 27 in the order of step numbers attached to each figure, the order of each process may be changed as appropriate without departing from the spirit of the overall flow. can. Incidentally, in the above example, the output processing means 72c changes the light emitting state of each light emitting section 78, but the present invention is not limited to this. may be configured.

As described above, the oxygen capsule 10 according to the present embodiment includes the main body 20 formed in a cylindrical shape, the first door 30 attached to one opening of the main body 20 so as to be openable and closable, and It has a second door 40 attached so that the other opening can be opened and closed. Therefore, animals etc. that have entered the room through the first door 30 can be allowed to exit through the second door 40. Therefore, it is possible to promote smooth exit without placing any burden on the animal. That is, it is possible to reduce the physical burden and psychological burden upon leaving the animal, and it is possible to alleviate the stress placed on the animal during care with an oxygen capsule.

Further, the oxygen capsules 10 are for bringing the main body 20 into close contact with each of the first door 30 and the second door 40, and a plurality of oxygen capsules 10 are provided in correspondence with each of the first door 30 and the second door 40. It has a main fastening means 11. Therefore, even when the internal pressure of the oxygen capsule 10 is increased, the state in which the door is brought into close contact with the main body portion 20 can be maintained, and the airtightness of the oxygen capsule 10 can be maintained. For each door, the main fastening means 11 are preferably arranged evenly at predetermined intervals. Furthermore, the oxygen capsule 10 has a plurality of auxiliary fastening means 12 provided in correspondence with each of the first door 30 and the second door 40. Therefore, the force for pressing each door against the main body portion 20 can be compensated for, and the load applied to the main fastening means 11 can be distributed. The plurality of auxiliary fastening means 12 may be arranged between the two main fastening means 11 in order to evenly distribute the load applied to the main fastening means 11.

In addition, the oxygen capsule 10 includes a first drive mechanism section 50A that includes an electric motor that serves as a power source for opening and closing the first door 30, and a second drive mechanism section 50B that includes an electric motor that serves as a power source for opening and closing the second door 40. It has . Therefore, the work burden on the user can be reduced compared to the case where the door is opened and closed manually. The oxygen capsule 10 also includes an opening/closing device 70 that controls the motors of the first drive mechanism section 50A and the second drive mechanism section 50B. Then, the opening/closing processing device 70 drives the electric motor of the first drive mechanism section 50A only when all the main fastening means 11 corresponding to the first door 30 are in the open state, and drives the electric motor of the first drive mechanism section 50A, and The electric motor of the second drive mechanism section 50B is configured to be driven only when the main fastening means 11 is in the open state. Therefore, it is possible to prevent a situation in which the electric motor is driven while the main fastening means 11 is closed. In addition, in order to detect whether or not the auxiliary fastening means 12 is in the open state, the auxiliary fastening means 12 may be provided with a detection means 11s. In this case, it is preferable that the information processing means 72a manage the detection data from the detection means 11s provided in the auxiliary fastening means 12. The drive processing means 72d drives the electric motor of the drive mechanism section 50 corresponding to each door only when all the main fastening means 11 and auxiliary fastening means 12 corresponding to each door are in the open state. good. However, it is not necessary to provide each fastening means with the detection means 11s.

Further, the oxygen capsule 10 has an opening/closing support section that is provided at the lower end of each of the first door 30 and the second door 40 and includes a wheel section. Therefore, it is possible to reduce the burden on each opening/closing mechanism section 60, which is a coupling mechanism between the main body section 20 and each door, and to facilitate the opening/closing operation of each door. However, the oxygen capsule 10 does not need to provide an opening/closing support part at the lower end of each door. In particular, when the oxygen capsule 10 is manufactured for use by a small number of people or small animals, the first door 30 and the second door 40 are not so heavy, so each door can be opened and closed smoothly without providing an opening/closing support part. It can be carried out.

The main body portion 20 has an entrance/exit hole 20h formed for entry/exit. Further, the oxygen capsule 10 has a door portion 15 that is attached to the entrance/exit hole 20h. The door portion 15 includes a door body 1, a first sliding mechanism 2, and a second sliding mechanism 3. That is, the oxygen capsule 10 is provided with the first sliding mechanism 2 that slides the door body 1 in the first direction so as not to interfere with the outward pressure applied to the door body 1, so that the oxygen capsule can be moved in and out. It is possible to improve the airtightness of the door while having a simple structure.

Here, the embodiments described above show specific examples of oxygen capsules, and the technical scope of the present invention is not limited to these embodiments. For example, although the above embodiment has been described on the premise that the oxygen capsule 10 is used by a horse, the oxygen capsule 10 is not limited to this, and the oxygen capsule 10 may be used by an animal other than a horse, and the oxygen capsule 10 may not be used by a human. Good too. When the oxygen capsule 10 is used by an animal other than a horse or a human, the size, structure, etc. may be changed depending on the animal. At least one of the first door 30 and the second door 40 may be configured to be opened and closed manually. That is, the oxygen capsule 10 does not need to include at least one of the first drive mechanism section 50A and the second drive mechanism section 50B. However, especially when the oxygen capsule 10 is manufactured for large animals such as horses and cows, the weight of the door increases accordingly, which increases the work burden on the user when opening and closing the door. Therefore, it is preferable that the first door 30 and the second door 40 be configured to be able to be opened and closed automatically. The oxygen capsule 10 may be configured to stop driving the electric motor for opening and closing the door when a certain load is applied to the electric motor. Such a configuration may be realized by the drive processing means 72d, or may be realized by using a limit switch or the like.

The plurality of fastening means may include a cylinder, for example, and may be configured to automatically bring the door flange into close contact with the main body flange (hereinafter referred to as automatic fastening means). In this way, it is possible to reduce manual work by the user, thereby increasing convenience and shortening the time required to work on the oxygen capsule 10. However, one or more automatic fastening means and at least one of the main fastening means 11 and the auxiliary fastening means 12 may be provided in combination in association with each door. The oxygen capsule 10 may be configured to have only the main fastening means 11 without the auxiliary fastening means 12. In this case, the plurality of main fastening means 11 corresponding to each door may be a combination of one or more automatic fastening means and one or more manual main fastening means as shown in each figure. It's okay. Note that instead of the plurality of fastening means, the oxygen capsule 10 may have, for example, one or more sealing means having a structure that simultaneously sandwiches the first door 30 and the second door 40. The sealing means may be of removable construction.

In the above embodiment, an example was shown in which the oxygen capsule 10 has two opening/closing operation parts 75, but the present invention is not limited to this. The oxygen capsule 10 may include one opening/closing operation section 75 including a changeover switch that accepts the designation of the door to be operated. In this case, the first button 77a in the opening/closing operation section 75 described above may have a function as a changeover switch. The shape, number, and arrangement of the pedestal portions 22 are not limited to the examples shown in each figure, and can take various configurations. The structure of the first sliding mechanism 2 and the second sliding mechanism 3, that is, the number of each rail, how each rail is attached, the structure of the rail and the engaging part, etc., is not limited to the above example, and may be changed as appropriate. Can be done.

Each figure shows an example in which the entrance/exit hole 20h is formed at the center in the left-right direction, but the invention is not limited to this, and the entrance/exit hole 20h may be formed at a location on the left side or at a location on the right side may be done. In the above example, the door part 15 is opened when the door body 1 moves to the first door 30 side. A structure may also be adopted in which the opening state is achieved by moving to .
