Abstract
The utility model relates to an environmental protection type mercury thermometer which can prevent mercury pollution. A common mercury thermometer made of glass is sheathed with a casing which is made of plastics or metal, heat-conductive filling material and a rubber seal are arranged in the front end of the casing, and the rear end is provided with non-skid buckling rings which can be sheathed with fingers. The utility model can effectively prevent the leakage and pollution of mercury after the thermometer is damaged for the convenience of recycling the mercury, and the non-skid rings can reduce the probability of being damaged due to the frequent throwing operations, which prolongs to service life of the thermometer.
Description
The utility model relates to a kind of environment-friendly type mercury clinical thermometer that prevents mercury pollution.
At present, the domestic clinical thermometer overwhelming majority is time-honored mercury clinical thermometer.Mercury clinical thermometer has accurate, reliable, easy to use and cheap advantage, but the shortcoming of its maximum is to adopt poisonous mercury.Owing to need frequent whipping when using, very easily damaged leakage and the pollution that causes mercury of mercury clinical thermometer, serious harm health.In Europe, Denmark, Norway, Sweden, Switzerland, France etc. pay attention to the country of environmental protection, completely forbid already and produce and use mercury clinical thermometer, and replaced by electronic thermometer or infrared thermometer.In China, abandon the mercury clinical thermometer of cheapness, practicality fully, promoting expensive electronics, infrared thermometer is unpractical (latter still need use mercury thermometer periodic calibration, poor reliability).
The purpose of this utility model provides a kind of environment-friendly type mercury clinical thermometer, and it can keep accurate, reliable, the inexpensive advantage of mercury clinical thermometer, can prevent the mercury environmental pollution again and increases the service life.
The purpose of this utility model is achieved in that on the simple glass mercury clinical thermometer, overlaps a shell of making of plastics or metal, adds heat conduction packing material and glue envelope in the shell front end, and there is the anti-slide fastener circle that is inserted in finger the rear end.The leakage of mercury when the shell front end can avoid clinical thermometer damaged, rear end button circle can significantly reduce the damage that whipping causes, and reaches the purpose that prevents mercury pollution, and wherein filling Heat Conduction Material is the key of guaranteeing the clinical thermometer accuracy.
Owing to adopt such scheme, under the situation that keeps the original accuracy of mercury clinical thermometer, prevent mercury pollution effectively and increase the service life.Its structure is very simple, does not increase how many costs, can make environment-friendly type mercury clinical thermometer possess cheap advantage, is convenient to promote.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a mercury clinical thermometer outer casing construction drawing of the present utility model.
Fig. 2 is environment-friendly type mercury clinical thermometer one-piece construction figure.
4. mercury clinical thermometer of 1. front-end protection shells, 2. anti-skidding finger buckle circle 3. connecting bands (in clinical thermometer scale back) among the figure
Front-end protection shell (1) is linked to be an integral body by connecting band (3) and anti-skidding finger buckle circle (2) among Fig. 1, and the button circle broke away from (can will detain the gluing further reinforcing of circle) when this structure can prevent the clinical thermometer whipping.
In the embodiment of Fig. 2, overlap the shell that nontoxic plastics of anti-ethanol of usefulness or stainless steel are made on the common mercury clinical thermometer; add heat conduction packing material and glue envelope in the front-end protection shell (1), the connecting band (3) by the clinical thermometer back is connected with anti-skidding finger buckle circle (2).The front end outer casing thickness is determined (about 0.2mm) to take into account parameters such as accuracy, retardation time and physical strength.Usually accuracy does not have obvious errors after the thermal equilibrium, is not more than 30 seconds retardation time.Shell did not break and causes mercury to leak to be as the criterion when physical strength was damaged with clinical thermometer.The damping of shocks district is done in the space of the about 1mm of front end reservation during assembling.
Shell and glue envelope require smooth no burr; Shell adopts colour code, as light green be oral thermometer, light blue is anus thermometre, pale red is meter for animal, white is industrial table.
Handle problems for the clinical thermometer that damages, can take to establish collection box, be responsible for the scheme of recycling by producer in each hospital.And widely propaganda in product description and medium, improve the common people's environmental consciousness.
The utility model also can be used for the protection of general mercury thermometer, and when the measurement temperature was higher, sheathing material can be selected heat resistant plastice or stainless steel and heat-resistant adhesive closure material for use.
Claims (3)
1. environment-friendly type mercury clinical thermometer, the glass mercury clinical thermometer is characterized in that adopting plastics or metal to make shell protection clinical thermometer front end (in add the heat conduction packing material), and there is anti-skidding finger buckle circle the rear end.
2. environment-friendly type mercury clinical thermometer according to claim 1 is characterized in that: adopt the protectiveness shell mechanism design that prevents the mercury leakage pollution, make shell front end, interior filling Heat Conduction Material by nontoxic plastics of anti-ethanol or metal.
3. environment-friendly type mercury clinical thermometer according to claim 1 is characterized in that: link to each other with preceding end housing or disjunct anti-skidding finger buckle circle.
