Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a medicine storage for storing medicines.
[0002]
[Prior art]
The development of medical society in recent years has been remarkable, and there are a large number of medicines prescribed from hospitals. In addition, due to the revision of the Pharmaceutical Affairs Law, pharmacists are obliged to explain the content of prescription drugs to patients and have them be convinced before instructing patients to take them correctly. Under such circumstances, proper handling and management of pharmaceuticals has become a problem. Usually, when prescription medicines, OTC medicines (household medicines) purchased at pharmacies and drug stores are stored, refrigerated storage is often preferred. In recent years, in home medical patients, which are rapidly increasing, prescription infusion preparations for 1 to 2 weeks are becoming commonplace, and such medicines must be kept refrigerated for quality preservation and drug efficacy preservation.
[0003]
[Problems to be solved by the invention]
However, in refrigerators for home use, storage of pharmaceuticals is prohibited for reasons such as large control temperature distribution in the cabinet, accidental freezing of pharmaceuticals, and possible accidents when mixed with other foods. This is the current situation.
[0004]
Accordingly, an object of the present invention is to solve the above-described problems of the prior art and provide a medicine storage that can safely store prescription drugs in hospitals or OTC medicines purchased at pharmacies and drug stores in general households. .
[0005]
[Means for solving problems]
According to the first aspect of the present invention, in the medicine storage where the inside of the medicine storage body is cooled by the cooling means and controlled to a predetermined temperature by the temperature control means , the cooling means is embedded in the storage wall of the medicine storage body. In addition, the heating means is embedded inside the refrigerator rather than the cooling means, and the inside temperature is controlled within the optimum temperature range of the medicine by the operation of the heating means and the cooling means.
[0009]
The invention described in claim 1 has the following action.
[0010]
The internal temperature can be controlled within the optimal temperature range by increasing the internal temperature at the time of supercooling by burying the heating means inside the internal storage rather than the cooling means . In other words, since the inside of the warehouse is maintained at a certain temperature or higher, even when the ambient temperature of the medicine storage is lowered below freezing point, the inside temperature can be set to be higher than the lower limit of the optimum temperature range of the medicine. Can be prevented, and the medicine can be stored and managed safely at home.
[0017]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0018]
FIG. 1 is a perspective view showing an embodiment of a medicine storage according to the present invention. A medicine storage 10 shown in FIG. 1 is an OTC medicine cold storage, and includes a plurality of, for example, three shelves 13 in the medicine storage body 11 (inside 12). The shelf plate 13 is detachably supported by a pair of shelf receiving side plates 15 and a shelf receiving back plate 17. The medicine storage body 11 is provided with a door 20 that can be freely opened and closed.
A compressor and a condenser (not shown) are installed at the lower back of the medicine storage body 11, and the three storage walls 23 on both side walls and the back wall of the medicine storage body 11 meander to form an evaporator. The refrigerant pipes (cooling means) 25, 27, 29 are embedded. The refrigerant pipes 25, 27, 29, and a compressor and a condenser (not shown) are respectively connected by refrigerant pipes to constitute a refrigeration cycle.
[0019]
This chemical storage is a direct-cooling chemical storage that evaporates the refrigerant with the refrigerant pipes 25, 27, and 29 and directly cools the interior 12 through the storage wall 23.
[0020]
In this embodiment, as shown in FIG. 2, electric heaters (heating means) 31 meander in parallel so as to be located on the inner side of each warehouse wall 23 with respect to the refrigerant pipes 25, 27, 29. Buried.
[0021]
On the other hand, a temperature sensor 26 as temperature control means is disposed in the inside 12 of the medicine storage body 11. When the temperature of the inside 12 is detected by the temperature sensor 26 and the inside temperature reaches the lower limit set temperature by the cooling operation, the operation of the compressor (not shown) is stopped, and thereby the inside temperature is reversed and increased. When the upper limit set temperature is reached, the compressor is operated and the internal temperature is controlled within a predetermined range.
[0022]
If the interior 12 is supercooled, the electric heater 31 is immediately energized, and the heat of the electrical heater 31 is radiated to the interior 12 by the heating of the electrical heater 31, and the interior 12 is overcooled. Is prevented. In this case, the internal temperature is controlled within the optimum temperature range (for example, 2 to 8 ° C.) of the OTC pharmaceutical.
[0023]
This chemical storage is a so-called direct cooling type, and refrigerant pipes 25, 27, 29 are embedded in the storage wall 23 of the chemical storage main body 11, and further in parallel with the cooling means on the inside 12 side of the cooling means. An electric heater 31 is embedded.
[0024]
Therefore, since cooling or heating is performed uniformly throughout the entire wall 23 at the time of cooling and heating, the operation of the heating means and the cooling means causes the inside temperature to be within the optimum temperature range (for example, 2 to 8 ° C.) It becomes controllable evenly.
[0025]
Moreover, the locking mechanism 21 is provided in the upper surface of the chemical | medical agent storage main body 11, and the above-mentioned door 20 is comprised so that locking is possible. A key is built in the door 20, and the door 20 is prevented from being inadvertently opened by inserting the key into a key hole (not shown) of the locking mechanism 21 and locking the key.
[0026]
Therefore, according to this embodiment, the following effects (1) to (3) are obtained.
[0027]
(1) Unlike ordinary refrigerators for home use, the electric heater 31 embedded in the storage wall 23 is heated to maintain the interior 12 at a certain temperature (2 ° C.) or higher, which is suitable for storing OTC pharmaceuticals. Since the medicine can be stored at an appropriate temperature in the cabinet 12 because it is configured to be held in the range (2 to 8 ° C.), even when the ambient temperature of the medicine storage 10 falls below freezing point, Freezing can be reliably prevented.
[0028]
(2) Since the refrigerant pipes 25, 27, 29 and the electric heater 31 are embedded in the storage wall 23 in parallel, it is possible to reduce the size of the chemical storage, and thus even in a home with little installation space. , Its installation becomes easy.
[0029]
(3) Since a locking mechanism 21 having a keyhole is installed on the upper surface of the medicine storage body 11, it is possible to prevent children and the like from inadvertently opening the inside 12 to the outside. Can be reliably prevented.
[0030]
As mentioned above, although this invention was demonstrated based on one Embodiment, this invention is not limited to this. For example, instead of the refrigerant pipes (cooling means) 25, 27, 29 and the electric heater 31 of the above embodiment, thermoelectric conversion elements (Peltier elements) as cooling heating means may be installed. This Peltier element cools the inside 12 when the temperature in the inside 12 is equal to or higher than the upper limit of a temperature range (for example, 2 to 8 ° C.) suitable for storing medicines, and is below the lower limit of the temperature range. When this happens, the inside 12 is heated, and the inside 12 is always kept in the temperature range.
[0031]
Further, for example, a temperature sensor 33 different from the temperature sensor 26 is installed in the interior 12 of the embodiment, and the temperature in the interior 12 detected by the temperature sensor 33 is a temperature range suitable for pharmaceutical products. When the value exceeds the limit, a light or sound may be generated by an alarm generator. In this case, since the alarm device issues an alarm when the medicine is stored in the storage room 12 at a temperature outside the temperature range suitable for the medicine, the user can refrain from using such medicine. Safety can be increased.
[0032]
The locking mechanism 21 of the above embodiment may be a simple locking mechanism that prevents the door or the like from being opened even by a mischief of an infant or the like.
[0033]
【The invention's effect】
As described above, according to the chemical storage according to the present invention, the internal temperature is increased by burying the heating means inside the internal storage rather than the cooling means , thereby increasing the internal temperature during supercooling. The internal temperature can be controlled within the optimum temperature range . In other words, since the inside of the warehouse is maintained at a certain temperature or higher, even when the ambient temperature of the medicine storage is lowered below freezing point, the inside temperature can be set to be higher than the lower limit of the optimum temperature range of the medicine. Can be prevented, and the medicine can be stored and managed safely at home.
