Description

  The present invention relates to an intensive care apparatus for animals, and more particularly, to an intensive care apparatus for animals having a configuration in which an oxygen cylinder and an oxygen concentrator can be used selectively or simultaneously for supplying oxygen.

  The intensive care unit for animals used in veterinary hospitals is used as an intensive care unit with severe symptoms or containing patient animals such as dogs, cats, monkeys, ferrets, etc. immediately after surgery, observing the progress and administering medications, etc. It is what is done. In general, it is made of stainless steel and is formed firmly, and an open / close door is provided on the front side. Furthermore, a gas supply path for keeping the oxygen concentration of the atmosphere in the intensive care room high, an air conditioner for managing the temperature of the atmosphere, and the like are provided.

  FIG. 9 is a perspective view of an intensive care unit for animals according to the prior art. 9, 90 is an intensive care unit for animals, 91 is a room A, 91a is an open / close door, 92 is a B room, 92a is an open / close door, 93 is a C room, 93a is an open / close door, 94 is a control / air conditioning unit room, 95 is an open / close door, 96 is an operation panel, 97 is an oxygen supply management panel, 98 is an oxygen concentrator pipe connection port, and 99 is an oxygen cylinder pipe connection port.

  FIG. 9 shows an intensive care apparatus for animals disclosed in Japanese Patent Application Laid-Open No. 2014-57774. The intensive care unit 90 for animals includes a control unit such as an oxygen supply provided in a control / air conditioning unit room 94 for the A room 91, the B room 92, and the C room 93 which are intensive care rooms, an air conditioner, oxygen The supply device can perform oxygen supply and air conditioning individually. The open / close doors 91a, 92a and 93a provided on the front side are opened and closed to accommodate patient animals and perform treatment. The room temperature and the like can be set on the operation panel 96, and the room temperature and set values of each intensive care unit can be displayed. Similarly, the state of oxygen supply to each intensive care unit can be confirmed on the oxygen supply management panel 97. Moreover, it is possible to perform maintenance of the equipment provided inside by opening the open / close door 95. According to the above configuration, the temperature or oxygen concentration in the A chamber 91, the B chamber 92, and the C chamber 93 can be individually set by appropriately operating the operation panel 96 and the oxygen supply management panel 97, and further, the room temperature and the like. It is also possible to grasp this information as appropriate. In addition, when supplying oxygen to each intensive care unit, a supply source is an oxygen concentrator and an oxygen cylinder oxygen (not shown) connected via an oxygen concentrator pipe connection port 98 and an oxygen cylinder pipe connection port 99. Thus, either the oxygen cylinder or the oxygen concentrator can be appropriately selected by operating the operation panel 96.

  As described above, even if an environment where appropriate treatment can be performed according to the state of the patient animal is prepared, the function may not be sufficiently exhibited due to the influence of the external device. That is, some oxygen concentrators cannot perform oxygen concentration according to specifications. In addition, there is a case in which the oxygen concentration of the atmosphere in the intensive care unit cannot be maintained because the adsorption capacity of the nitrogen gas adsorbent decreases while the oxygen concentrator is continuously used. Furthermore, for example, the oxygen concentrator itself can be used without any problem when the oxygen concentration in the atmosphere in the intensive care unit is maintained at 30%, but it does not reach 40% no matter how many hours it tries to increase it to 40%. Can cause various problems.

  If the veterinarian thus causes or is foreseeable to have problems with the oxygen concentrator itself, and the oxygen concentrator becomes unreliable, an oxygen cylinder can be used as an oxygen source for the animal intensive care unit. I have to choose. However, the oxygen cylinder has a considerably higher cost of oxygen gas per unit amount than the oxygen concentrator. Therefore, if only the oxygen cylinder is used continuously, the cost for treating the patient animal also increases.

  FIG. 4 is a flowchart (1) showing an oxygen supply procedure of the intensive care unit for animals according to the first embodiment. FIG. 5 is a flowchart (2) showing the oxygen supply procedure of the intensive care unit for animals according to the first embodiment. Furthermore, FIG. 6 is a flowchart (3) showing an oxygen supply procedure of the intensive care unit for animals according to the first embodiment. In addition, FIG. 7 is a flowchart (4) showing an oxygen supply procedure of the intensive care unit for animals according to the first embodiment.

  Next, the oxygen supply operation of the intensive care apparatus for animals 10 according to the first embodiment of the present invention will be described from the start of use of the intensive care apparatus 10 for animals. First, as shown in FIG. 4, on the operation panel 71, the selection screen of each oxygen supply mode shown in FIG. 1 is displayed (S1), and a veterinarian or the like can select either the hybrid mode or the manual mode. Put it in a state. When the hybrid mode is selected on the operation panel 71 (S2), the normal mode and the active mode are further selected. When the normal mode is selected (S3), a signal is transmitted from the control unit 30 to the electromagnetic three-way valve 20 so that the conduit 37 on the oxygen concentrator 35 side and the conduit 39a are in communication with each other. (S4) At the same time when the procedure of S4 is executed, or immediately after the procedure of S4 is executed, the electromagnetic release valve 24 is closed and the gas supplied from the oxygen concentrator 35 is sent to the conduit 39a. Like that. At the same time, measurement of the oxygen supply time for the A chamber 11, the B chamber 12 and the C chamber 13 is started (S6). In the case where oxygen is selectively supplied to any one or two intensive care units of the A room 11, the B room 12, and the C room 13, the electromagnetic shut-off valve 21, the electromagnetic shut-off valve 22, Of the electromagnetic shut-off valve 23, the electromagnetic shut-off valve in the intensive care unit that is not supplied is closed.

  Subsequently, of the oxygen concentration sensor 31, the oxygen concentration sensor 32, and the oxygen concentration sensor 33 at the time when 10 minutes have passed since the start of oxygen supply, the intensive care unit in use, that is, the intensive care unit containing the patient animal is used. The oxygen concentration value of the corresponding oxygen concentration sensor is measured, and it is determined whether the concentration has reached the set value (S7). It should be noted that the time from the start of oxygen supply to the time when the procedure of S7 is performed may be appropriately set on the operation panel 71 according to the condition of the patient animal, such as 15 minutes, 20 minutes, or 25 minutes. When the set value is reached, in order to stop the oxygen supply to the intensive care unit, the electromagnetic release valve 24 is opened (S8), and the electromagnetic stop valve corresponding to the intensive care unit supplying oxygen is set. Close (S9). Since the oxygen concentration in the intensive care unit's atmosphere gradually decreases as the patient's animal breathes, the oxygen concentration sensor measures whether the oxygen concentration in the intensive care unit's atmosphere during use is 1% or more lower than the set value. The value is confirmed (S10). The predetermined value may be set to a concentration that is 0.5% or 1.5% lower than the set value according to the condition of the patient animal. If it is greater than the set value, repeat the confirmation of the measured value. When the set value is not reached, as shown in FIG. 6, the conduit 37 and the conduit 39a on the oxygen concentrator 35 side are in communication with the electromagnetic three-way valve 20 (S20), and the procedure of S20 is performed. Or immediately after executing the procedure of S20, the electromagnetic release valve 24 is closed so that the gas supplied from the oxygen concentrator 35 is sent to the pipe line 39a (S21). When oxygen is supplied from the oxygen concentrator 35 to the intensive care unit, the oxygen concentration increases. Therefore, the measured value of the oxygen concentration sensor is confirmed (S22). If the measured value is less than the set value, the confirmation of the measured value is repeated. . When the measured value is equal to or greater than the set value, the electromagnetic release valve is opened to stop the oxygen supply (S23), and then the electromagnetic stop valve corresponding to the intensive care unit in use is closed. And it progresses to the procedure of S15 of FIG.

  Also, in the procedure of S7 in FIG. 4, when the oxygen concentration value after a predetermined time has elapsed from the start of oxygen supply has not reached the set value, a signal is transmitted from the control unit 30 as shown in FIG. The electromagnetic release valve 24 is opened (S11), and the pipeline 38 on the oxygen cylinder 36 side and the pipeline 39a communicate with each other simultaneously with the execution of the procedure of S11 or immediately after the execution of the procedure of S11. The electromagnetic three-way valve 20 is switched (S12). While supplying oxygen from the oxygen cylinder 36, the oxygen concentration value of the oxygen concentration sensor corresponding to the intensive care unit in use is measured, and it is determined whether or not the concentration has reached the set value (S13). If the set value is not reached, the measurement is repeated, and if the set value is reached, the electromagnetic release valve 24 is closed (S14). Next, the measured value of the oxygen concentration sensor is checked whether or not the oxygen concentration of the atmosphere in the intensive care room in use is equal to or higher than the set value (S15). If it is greater than the set value, repeat the confirmation of the measured value. When the set value is not reached, the electromagnetic three-way valve 20 is switched so that the pipe line 37 and the pipe line 39a on the oxygen concentrator 35 side communicate with each other (S16), and simultaneously with the execution of the procedure of S16, or Immediately after performing the procedure of S16, the electromagnetic release valve 24 is closed (S17), and oxygen supply from the oxygen concentrator 35 is performed. Next, in spite of the oxygen supply, the measured value of the oxygen concentration in the atmosphere in the intensive care unit in use is 1% or more lower than before the oxygen supply, or the oxygen supply from the oxygen concentrator 35 is performed. If it matches any of the conditions that the oxygen concentration does not change even after 5 minutes from the start, it is determined that the open / close door of the intensive care unit in use is not properly closed (S18). The opening / closing door is notified by the display on the operation panel 71 or notification by e-mail. The procedure after S3 is an oxygen supply procedure when operating in the normal mode 84 of the hybrid mode 82. As described above, in the normal mode 84, oxygen is mainly supplied from the oxygen concentrator 35, but the supply may be switched from the oxygen cylinder 36 depending on the determination result in the control unit 30.

  The active mode 83 of the hybrid mode 82 is a procedure that proceeds from FIG. That is, as shown in FIG. 7, a signal is transmitted from the control unit 30 to the electromagnetic three-way valve 20 so that the pipe line 38 on the oxygen cylinder 36 side and the pipe line 39a are in communication (S25). Next, the oxygen concentration of the atmosphere in the intensive care room in use is measured, and it is confirmed whether or not the measured value has reached the set value (S26). When the set value has not been reached, the measurement value is repeatedly checked. If the set value has been reached, the electromagnetic shut-off valve corresponding to the intensive care unit in use is closed and the oxygen cylinder 36 is turned off. The oxygen supply is stopped (S27). Since the oxygen concentration in the intensive care room atmosphere gradually decreases due to the patient's breathing, the oxygen concentration sensor measures whether or not the oxygen concentration in the intensive care room atmosphere in use is 1% or more lower than the set value. The value is confirmed (S28). If it is greater than or equal to the predetermined value, the confirmation of the measured value is repeated. When the predetermined value is not reached, the pipe 37 on the oxygen concentrator 35 side and the pipe 39a are in communication with each other (S29), and the electromagnetic release valve 24 is closed (S30). The supplied gas is sent to the pipe line 39a. If the oxygen concentration is about 1% lower than the set value, even if oxygen is supplied from the oxygen concentrator 35, the oxygen concentration at the set value can be recovered in a short time. In the animal intensive care device 10 according to this embodiment, the amount of oxygen cylinders 36 used is reduced in this way.

  Next, in spite of the oxygen supply, the measured value of the oxygen concentration in the atmosphere in the intensive care unit in use is 1% or more lower than before the oxygen supply, or the oxygen supply from the oxygen concentrator 35 is performed. If it matches any of the conditions that the oxygen concentration does not change even after 5 minutes from the start, it is determined that the open / close door of the intensive care unit in use is not properly closed (S31). As in the normal mode 84, the opening / closing door is notified by the display on the operation panel 71 or notification by e-mail. Next, the electromagnetic release valve 24 is opened (S33), and the process returns to the step S25 simultaneously with the execution of the step S33 or immediately after the execution of the step S33.

  In addition, when it is desired to use either the oxygen concentrator 35 or the oxygen cylinder 36 instead of the hybrid mode 82 in which the oxygen concentrator 35 and the oxygen cylinder 36 are used together, or when the oxygen concentrator 35 fails, the oxygen cylinder 36 When the remaining amount of oxygen is insufficient, oxygen can be supplied in the manual mode 85. As shown in FIG. 4, when the manual mode 85 is selected in the procedure of S2 and then the oxygen cylinder 36 is selected (S34), the line 38 on the oxygen cylinder 36 side and the line 39a are electromagnetically communicated with each other. The three-way valve 20 is switched (S35). When the oxygen concentrator 35 is selected, the conduit 37 and the conduit 39a on the oxygen concentrator 35 side are communicated (S36), the electromagnetic release valve 24 is closed (S37), and the oxygen concentrator 35 is supplied. The gas is sent to the conduit 39a.

  As described above, the intensive care apparatus for animals 10 according to the first embodiment of the present invention includes any one or two of the A room 11, the B room 12, and the C room 13, or the three rooms. When everything is used, when only oxygen concentrator 35 is supplied to an intensive care unit that uses only oxygen or a gas having a higher oxygen concentration than the surrounding atmosphere, and oxygen is insufficient after a predetermined time In addition, since the supply is switched to the supply using only the oxygen cylinder 36, the oxygen concentrator 35 can be used within the range of the supply capacity, and the portion where the supply capacity is insufficient can be compensated by the oxygen cylinder 36. As a result, the amount of oxygen gas used in the oxygen cylinder 36 can be reduced. Further, not only can the oxygen concentrator 35 be used within the range of its supply capacity, but also the use that gives priority to the immediacy of increasing the oxygen concentration of the atmosphere in the intensive care unit to the set value as quickly as possible can be performed. It becomes like this. Furthermore, when the oxygen concentration of the atmosphere in the intensive care unit decreases, oxygen is supplied from the oxygen concentrator 35 until the oxygen concentration reaches the set value again. In addition, it is possible to suppress the oxygen supply by the oxygen cylinder 36 and reduce the cost related to the treatment of the patient animal. In addition, when the oxygen concentration in the atmosphere in the intensive care chamber decreases, oxygen is supplied from the oxygen cylinder 36 when the oxygen supply from the oxygen concentrator 35 is insufficient, so the oxygen concentration in the atmosphere in the intensive care chamber is reduced. It becomes possible to maintain it appropriately.

  Furthermore, an intensive care unit for animals according to a second embodiment of the present invention will be described. FIG. 8 is a block diagram of components related to oxygen supply of the intensive care unit for animals according to the second embodiment. In FIG. 8, 40 is an intensive care unit for animals, 41 is a room A, 42 is a room B, 43 is a room C, 51, 52, 53, 54, 55 and 56 are electromagnetic shut-off valves, 57 is an electromagnetic open valve, 58 Is a speed controller, 60 is a control unit, 61, 62 and 63 are oxygen concentration sensors, 65 is an oxygen concentrator, 66 is an oxygen cylinder, 67a is a pipe, 67b is a branch pipe, and pipes 67c, 67d, 67e and 68a. 68b, 68c and 68d are conduits.

  In the intensive care unit for animals 40 according to the second embodiment, the pipe line 67a connected to the oxygen concentrator 65 is connected to the pipe lines 67c, 67d and 67e without passing through the electromagnetic three-way valve. An electromagnetic closing valve 51, an electromagnetic closing valve 52, and an electromagnetic closing valve 53 are provided in the middle of the pipe 67c, the pipe 67d, and the pipe 67e. Further, the pipe 68a connected to the oxygen cylinder 66 is also connected to the pipes 68b, 68c and 68d without passing through the electromagnetic three-way valve. An electromagnetic closing valve 54, an electromagnetic closing valve 55, and an electromagnetic closing valve 56 are provided in the middle of the pipe 68b, the pipe 68c, and the pipe 68d. The pipes 67c, 67d and 67e, and the pipes 68b, 68c and 68d are connected to the A chamber 41, the B chamber 42 and the C chamber 43, respectively, and are sent out from the oxygen concentrator 65 and the oxygen cylinder 66. Gas can be sent. The branch pipe 67b, the electromagnetic release valve 57, the speed controller 58, the control unit 60, the oxygen concentration sensors 61, 62 and 63, the oxygen concentrator 65, and the oxygen cylinder 66 are the animal concentration according to the first embodiment. This is the same as the branch pipe 37a, the electromagnetic release valve 24, the speed controller 25, the control unit 30, the oxygen concentration sensors 31, 32 and 33, the oxygen concentrator 35, and the oxygen cylinder 36 of the treatment apparatus 10.

  In the intensive care unit 40 for animals according to this embodiment, the pipe line connected to the oxygen concentrator 65 and the pipe line connected to the oxygen cylinder 66 are provided in different systems, so the configuration of the pipe line is complicated. However, the same operation as that of the intensive care apparatus for animals 10 according to the first embodiment can be performed, and the same effect as that of the intensive care apparatus 10 for animals according to the first embodiment can be obtained. Further, since oxygen can be supplied simultaneously from the oxygen concentrator 65 and the oxygen cylinder 66, oxygen is supplied simultaneously from the oxygen concentrator 65 and the oxygen cylinder 66 when the use of the intensive care unit is started. Thus, it is possible to increase the oxygen concentration of the atmosphere in the intensive care unit in a shorter time.

  It should be noted that the present invention is not limited to the description of each embodiment described above, but various combinations can be made without departing from the scope described in each claim, such as a combination of configurations of a plurality of embodiments. It is possible to add deformation.
