Unless otherwise specified. The consumables and accessories used in the following embodiments are available for purchase.

[0042] The present invention provides a ward for improving health. In all examples of the present invention, the ward has the following common features: the ward comprises glass window, all or part of the glass window has a glass structure which can be penetrated through by UVB, and the glass structure is a controllable glass structure, the controllable glass structure is glass structure, of which UVB transmission amount is controllable.

[0043] In further examples, the controllable glass structure refers to the glass structure of the glass windows acting as the structure of the ward that UVB can penetrate through only in a period of time.

[0044] In some examples, the glass structure refers to a flat glass adhered by a membrane or coating which can be penetrated through by UVB.

[0045] In specific examples, the membrane or coating blocks UVA and UVC.

[0046] In more specific embodiments, the UVB transmissivity is above 80%; or above 60%; or above 50%; or no less than 30%. The present invention is not limited to the transmissivity of above specific numerical values, for example, glasses with other UVB transmissivity can be prepared for being installed in the ward, as shown in table 1 in the following experimental example.

[0047] In some other examples, the glass structure refers to no or few ultraviolet rays absorption material is added in the glass preparation.

[0048] In the preferred example, the ultraviolet rays absorption material is selected from the group consisting of Fe.sub.2O.sub.3, CeO.sub.2, T.sub.iO.sub.2 or other common ultraviolet rays absorption materials.

[0049] In further preferred examples, the glass structure refers to UVA and/or UVC absorption material is added in the glass preparation, that is to say, no or few ordinary ultraviolet absorption materials are added in the glass structure, but UV absorption materials that specifically absorb UVA and/or UVC are added.

[0050] Specifically, UVA absorption material include: 1,2-hydroxy-4-methoxybenzophenone, which is benzophenone containing two ortho-hydroxies, with strong capacity of absorbing ultraviolet light with wavelength 330-370 nm(equivalent to UVA); and/or, Tian Lai Shi (annotation) M (TinosorbTMM), it has dual function of absorbing and scattering UVA-band ultraviolet rays, and has extremely high photostability; and/or 2,4-dihydroxy-benzophenone, it is also one kind of UVA absorbent commonly used in this field; and so on;

[0051] UVC absorption material include: 0.1% of Moringa leifera Oil, which can absorb UVC band rays (see Study on Anti-ultroviolet Properties of Moringa leifera Oil), etc.

[0052] Because of the short wavelength of UVC, most wave bands of UVC can be blocked by transparent plastic and ordinary glass, therefore, the glass structure can be a common glass coating with one or some of above UVA absorption materials.

[0053] It's well known in the art of glass, there are coated and uncoated 5 mm thick glass, including: ordinary uncoated white glass, uncoated blue glass and uncoated green glass, which can be penetrate by most of the ultraviolet (UVA+UVB), as well as coated blue glass and coated green glass, through which lower limit of wavelength of ultraviolet radiation penetrating is about 330 nm. In other words, most kinds of glass can block a part of UVA, and among them, the coated green glass have the strongest UVA barrier effect, therefore, the glass structure in this invention can also be green glass further coated with UVA absorption material and UVB absorption material.

[0054] Alternatively, an example that a specially glass that blocks full band ultraviolet rays coated with UVB transmission material can be directly applied; the UVB transmission material include: Ce.sup.3+ and/or Sm.sup.3+, or membrane or coating containing these two ions; Or other conventional UVB transmission materials or materials that can improve the transmission capability of glass to UVB in this field, like UVB phosphor powder.

[0055] Said UVB phosphor powder refers to calcium orthophosphate phosphor powder ((Ca, Zn).sub.3(PO.sub.4).sub.2:Tl), or, UVB phosphor powder recorded in Chinese Patent No. 201510698095.3.

[0056] In addition, high temperature melting method, a method commonly used in the art of glass, can also be used to synthesis luminescent borate glass with rare earth ion Sm.sup.3+ mixed (see Characterization for Multi-channel Transition And Fluorescence Property of Trivalent Rare Earth Ion in Borate Glasses), or using melt quenching technology to prepare calcium borate glass mixing Sm.sup.3+, of which the components is: 30CaO-60B.sub.2O.sub.3-10AgNO.sub.3-xSm.sub.2O.sub.3(x=0.05,0.25,0.5,1,3,5 (mole fraction)) (the preparation process see Preparation and Luminescence Properties of Sm.sup.3+ doped Calcium Borate Glasses Containing Silver), both of them can penetrate UVB rays of sunlight primely, and their UVB transmissivity can be adjusted by adjusting the proportion of Sm.sup.3+ ions during preparation.

[0057] Various conventional materials, conventional methods used in above specific examples are exemplary, rather than exhaustive. Based on this disclosure, a person skilled in the art can find the other regular materials or methods which play the same role in preparing a glass that only let UVB penetrating through, but block UVA and UVC.

[0058] In the specific embodiments, the period of time refers to 0.2 hour to several hours in the daytime.

[0059] In more specific embodiments, the controllable glass structure comprises the glass structure and a movable structure on the glass window which can move up to the glass structure to block UVB penetrating through; or comprises the glass structure and a covering part which covers the glass window, the covering parts includes curtain, In addition to curtain, other blocking sunshine structures are also available, such as shutters, etc. The existing manual, automatic control, or intelligent control means can be combined, to further improve the convenience of operating glass window of the invention .

[0060] Further, the ward also includes a detection structure 2, as shown in FIG. 1, and the detection structure 2 is set inside of the wall of the ward or inside the controllable glass structure 1, the detection structure 2 comprise a detection part 21 which detects the UVB transmission amount, and a control part 22 which is connected to the detection part 21, the control part 22 control the movable structure 12 or the covering part of the controllable glass structure 1 to cover the glass structure 11 according to the UVB transmission amount detected by the detection part 21.

[0061] Specifically, the control part is a intellisense automatic control unit (not shown in the figure) which is built-in inside the detection structure; it can also be a form of an external remote control (not shown in the figure); the detection part detects the UVB transmission amount, then transmits the data of the UVB transmission amount to intellisense automatic control unit; as to intellisense automatic control unit, based on its internally-preset recognition program, when the UVB transmission amount received is higher than a certain value, it will be triggered to control the movable structure to cover the glass structure, in order to block the sunlight to enter the room.

[0062] The form of an external remote controller refers to, the detection part is equipped with a built-in control chip inside and an intelligent display screen outside, and the control chip is connected to the external remote controller wirelessly or through wire. The external remote controller is connected to the movable structure wirelessly or through wire at the same time; the detection part detects the UVB transmission amount and transmit the data of the UVB transmission amount to said intelligent display screen, people (patients/subjects/staff) in the ward read the data displayed on intelligent display screen. If people in the ward think the UVB transmission amount has reached the expectant, they can control the movable structure to cover the glass structure by using said external remote controller directly, in order to block sunshine entering the ward.

[0063] Experiment example: Vitamin D generation effect contrast between the ward disclosed by the present invention, the general ward and the sunbath outside.

[0064] It's well-known in the medical field, the concentration of 25-hydroxy vitamin D (25(OH)D) in the serum can represent the level of vitamin D in organism; and, levels of 25(OH)D in vivo are classified as follows:

Vitamin D insufficiency: 21-29 ng/mL (52.5-72.5 mmol/L)

Vitamin D deficiency: <20 ng/mL (<50 mmol/L)

[0065] 500 subjects were selected in clinical trials and divided into 10 groups, and there were 50 people in each group. All subjects received test, and the test lasted for 7 days. First 8 groups are respectively arranged in the ward according any one of above example disclosed in this invention (not went out of the ward during the test), the 9.sup.th group is arranged in the conventional ward (not went out of the ward during the test), the 10.sup.th group is arranged to walk around in outdoors and sunbath for 2 hours between 8 to 11 o'clock in the morning every day, and in other times they stayed in the conventional ward without go out; Subjects in each group were in a healthy and stable condition before the test, without any diseases related to vitamin D metabolism. They were consistent in their daily diet and did not take any vitamin supplements during the test.

[0066] After the test, the conventional method of clinical detection field was used to measure concentrations of 25-hydroxy vitamin D (25 (OH) D) in serum of all subjects in each group, and the average vitamin D level of subjects of each group was counted. The results are shown in table 1 below.

TABLE-US-00001 TABLE 1 Duration of the average sun exposure vitamin D level Group sun exposure UVB (unit: of subjects NO. types transmissivity hour/day) (unit: ng/mL) 1 Ward 90% 0.2 59 2 disclosed in 80% 0.5 80 3 invention 70% 0.7 66 4 60% 0.8 60 5 55% 0.6 55 6 50% 0.9 58 7 45% 1 62 8 30% 2 75 9 the Above 25 conventional 3 hours ward 10 Sunbath 2 hours 80 outside

[0067] UVB transmissivity listed in above table 1 corresponding to group No. 1 to 8 refers to the UVB transmissivity of the glass window of the ward in which the subjects of the group were stayed. The column of Duration of sun exposure, refers to the duration time that sunlight penetrating through the glass window of the present invention ward and/or the conventional ward, for example, if the window is with curtain, it means the duration time that curtain was open (curtain was closed in the other time, and sunlight was blocked to enter indoor). Subjects in the wards could shed excess clothing, to expose more skin to accept the sunshine penetrated in room. In the above table, it can be seen that, the duration of sun exposure hours in the ward of the present invention is less than that of the conventional wards and sunbath outside as a whole, and obviously, the ward of the present invention have a good effect on providing UVB, at the same time, the duration of sun exposure in the ward of this invention is shorter, high efficient, to ensure the patients/subjects in the wards disclosed in this invention ward to receive sufficient UVB to produce sufficient vitamin D in organism to maintain organism health without going outside.
