温度にしようとするものであった。[Technical background of the invention and its problems] Conventionally, for example, blood tests or! Automatic biochemical analyzers that can automatically perform chemical analyzes such as urinalysis on many specimens at once are equipped with moisture-resistant equipment that allows the specimens and reagents in test tubes to react at a constant temperature. Equipped with equipment. The constant temperature device installed in the automatic biochemical analyzer is a so-called fluid circulation type constant temperature device, and must include a constant temperature bath containing a constant temperature medium such as water for carrying out the reaction between the specimen sample and the reagent at a constant temperature. A temperature detection element detects the temperature of the constant temperature medium taken out from the constant temperature chamber through a pipe, and a temperature detection element that heats the constant temperature medium taken out of the constant temperature chamber based on the temperature detected by the temperature detection element. Equipped with a heater and a cooler for cooling, a pump for returning the heated or cooled constant temperature medium to the constant temperature chamber via a pipe, The temperature of the constant temperature medium inside the constant temperature chamber is brought to the set temperature by taking it out once, adjusting the temperature of the constant temperature medium taken out to the set temperature, and then returning the constant temperature medium to the humidity-resistant chamber. It was something.

がめった。However, conventional thermostats have the following problems. In other words, the constant temperature medium not only comes into contact with the hot water, but also its temperature is suitable for fungi to live, so fungi multiply within the constant temperature medium, and these fungi attach to the stagnation part of the circulation path of the constant temperature medium. This caused contamination and clogging of the circulation path, and also had an adverse effect on optical performance. In order to prevent the proliferation of such fungi, there is a method of mixing an algaecide into the constant temperature medium. However, this method has the disadvantage that the algae-preventing agent used is generally expensive and corrodes the metals (eg, aluminum, copper, etc.) used in the circulation path of the wet medium.

以下本発明の一実施例について図面を用いて説明する。[Summary of the Invention] The outline of the present invention for achieving the above object is to provide a constant temperature device that maintains a constant temperature in a constant temperature chamber by circulating a constant temperature medium. A special feature of the present invention is that it is constructed of a member that transmits ultraviolet rays, and is provided with an ultraviolet lamp that irradiates a moisture-resistant medium that passes through a circulation path made of the member with ultraviolet rays [Embodiment of the invention] An embodiment of the present invention will be described below with reference to the drawings.

(たとえば水銀ランプ)である。The drawing is a schematic diagram of a constant temperature device according to the present invention. In the drawings, reference numeral 1 denotes a constant temperature water bath that maintains the temperature of the sample in the test tube at a constant level using water, which is a moisture-resistant medium. The constant-temperature water tank 1 is connected to a circulation pump 2, a heating section 3, and a cooling section 5 by means of a vibro. The heating section 3 is made of a material (for example, quartz glass) that transmits ultraviolet rays. Reference numeral 4 denotes an ultraviolet lamp (for example, a mercury lamp) that irradiates ultraviolet light onto the water passing through the heating section 3.

に紫外線の照射を受けるので、ここでクビ滅する。Next, the operation of the embodiment apparatus having the above configuration will be explained. The water in the constant temperature medium is circulated by the circulation pump 2 through the constant temperature water bath 1, the heating section 3, and the cooling section 5 via the vibro. This water is irradiated with ultraviolet light by a mercury lamp 4 when passing through a heating section 3 made of quartz glass. Generally, cells have an absorption maximum at 260 mm, and when irradiated with light (ultraviolet light) of this wavelength, they die in a short time. Therefore, fungi generated in the "old hot water tank" are irradiated with ultraviolet rays when passing through the heating section 3, and are killed there.

ることがきる。As a result, not only can the proliferation of fungi be prevented, the contamination and clogging of the circulation path caused by fungi adhering to stagnant portions of the circulation path can be prevented, but also the optical properties can be improved.

を照Q」する場合をも含むものである。The reason why the ultraviolet rays are irradiated in the heating section 3 is that since the water remains there for heat exchange, the ultraviolet rays can be irradiated for a longer period of time than in other parts. However, the present invention is not limited to this, but also includes a case in which ultraviolet rays are irradiated in the circulation path of the human body.
