美國Harvard Apparatus成立于1901，是一家超過百年的實驗儀器生產和銷售的**公司。 美國Harvard Apparatus公司除向專業客戶提供動物手術臺外，還向客戶提供手術燈和照明設備、熱耦合溫度控制系統、動物恒溫毯、熱療墊、小動物孵育箱、各種手術放大器、內窺鏡
動物體內的溫度控制在動物恒溫毯*簡單-反饋回路，保持動物的溫度?多功能-可提供三種尺寸-成年小鼠，大鼠，貓，狗或大小相似的動物?選擇由硬式或柔性探頭： -硬式探頭可用于小鼠，
-柔性的探頭用于小鼠以及較大的動物（不適合小鼠）?新的輕重量包裝?改進的電子電路學?適合與高增益記錄設備?展示控制單元實際體溫，范圍35 °至40 °C（95 °到104 °F）
在手術期間，此動物恒溫毯能夠有效地監測動物體溫。動物的核心體溫由加熱毯監測，加熱毯中含有高柔性的絕緣發熱元件。此毯帶有２米長電纜，以連接控制部件。 | |
將柔性的測溫探頭插入直腸，并在控制器面板上設定所需溫度。探頭是一個精密熱敏電阻，被包裹在一個環氧樹脂小球內，該小球位于一根中空塑料管頂部；探頭帶有２毫米長的電纜，適用于各種各樣的實驗動物； | |
| 動物恒溫毯控制部件根據此測溫探頭測得的動物體溫數值，以比例方式調節低壓直流電源，從而控制加熱毯的溫度?？刂破黝A設溫度值為37°C，調節范圍為35°到40°C。如果動物的核心體溫下降，電源供給加熱毯的功率將自動增加；反之亦然。控制器上的液晶顯示屏將顯示探頭測得的動物體溫數值。一個橫置的發光二極管圖形顯示條將顯示輸送給加熱毯的功率水平。 | |
動物恒溫毯系統的部件包括：控制器，柔性的測溫探頭，加熱毯。 |

Wrap the animal tightly in the heating blanket， using tape ifnecessary. Insert the temperature-sensing probe rectally， and setthe required temperature by means of the control on the frontpanel.
Should the animal’s core temperature fall， power is automaticallyincreased to the blanket; conversely， power will automaticallyreduce if the animal’s temperature rises. During this process theanimal’s temperature is continuously displayed on a front panel LCDdisplay.
This homeothermic blanket system consists of three parts: a probe，a control unit， and a blanket. The flexible probe is a precisionthermistor encapsulated in a bead of epoxy resin at the top of aflexible hollow plastic tube. The 2 mm diameter probe is 100 mm (4in) long and has a 2 m (6 ft) long cable with plug for attachmentto the control unit. It is suitable for a wide range of laboratoryanimals from adult mice to large dogs.
The rigid probe is a stainless steel shaft with a diameter of 1.6mm. The shaft attaches to a 2 m (6 ft) cable with a plug thatconnects to the control unit. It is suitable for use with mice，rodents， rabbits， cats and dogs. The output of the temperaturesensing probe is used by the control unit to proportionally controlthe regulated， low-voltage DC supply to the blanket. This method ofcontrol alleviates the interference problems associated with thatof non-proportional control， such as switching contacts， thusenabling the system to be used in conjunction with high-gainrecording systems.
The control temperature is preset at 37°C (98.6°F) at the factory，but can be adjusted within the range of 35° to 40°C (95° to 104°F)by means of a control on the front panel. An LCD display on thecontrol unit continuously displays the probe temperature. Ahorizontal LED bar graph indicates the level of power beingdelivered to the blanket. When core temperature is substantiallybelow the desired temperature the bar graph will indicate maximumpower being delivered.
The blanket consists of a highly flexible insulated heatingelement， which can be folded without risking internal damage. It iselectrically floating， with respect to ground however， one end ofthe heating element can be grounded by a switch on the front panelof the control unit. The system operates satisfactorily whether ornot the blanket is grounded. Special circuitry eliminateselectrical noise thus permitting sensitive recordings.
Blankets are available in three sizes:
? Small Blanket: Measures 15 x 20 cm (6 x 8 in) and is suitable forrodents
? Medium Blanket: Measures 45 x 70 cm (18 x 27 in) and is suitablefor rabbits and cats
? Large Blanket: Measures 60 x 90 cm (24 x 36 in) and is suitablefor dogs
The blanket is supplied with a 2 m (6 ft) cable attached to a plugfor connection to the control unit. This system enables theresearcher to maintain an animal’s temperature within the presetrange of 35° to 40°C (95° to 104°F). Each system is suppliedcomplete with control unit， temperature probe， blanket and plasticcover for blanket.
