Novel nuclear medicine fuming cupboard activity meter well automatic lifting device

Abstract

The invention discloses a novel nuclear medicine fuming cupboard activity meter well automatic lifting device. A wheel carrier is installed on the lower surface of a bottom plate, the upper surface ofthe wheel carrier is connected with the lower surface of the bottom plate, idler wheels are installed on the inner wall of the wheel carrier, the outer walls of the idler wheels are movably connectedwith the inner wall of the wheel carrier, and a single hinge is installed on the upper surface of the bottom plate; and the lower surface of the single hinge is connected with the upper surface of the bottom plate, and a supporting rod is installed on the outer wall of the right side of the single hinge. According to the novel nuclear medicine fuming cupboard activity meter well automatic liftingdevice, through cooperation of a motor, a shaft sleeve and a rotating shaft, under the action of a gear and a fluted disc, a worker can feel physical fatigue easily, and the working efficiency is reduced; and in addition, a bracket lacks a traction device, the direction of a supporting plate cannot be mastered during moving, and an operator needs to frequently adjust an advancing route, so that resource waste of the novel nuclear medicine fuming cupboard activity meter well automatic lifting device is avoided, and the novel nuclear medicine fuming cupboard activity meter well automatic lifting device is suitable for application and popularization.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a novel nuclear medicine fume hood activity meter well automatic lifting device. Background technique [0002] The fume hood without duct ventilation does not require external pipes, does not pollute the external environment, and has little effect on the temperature of the laboratory, but the disadvantage is that the filter material must be replaced regularly, and the experimenter is more likely to be exposed to harmful gases than using an extraction fume hood. Because the extra exhaust fan is very close to the experimenter, it will cause noise. This type of fume hood has the following filtration procedures: use foam plastic pre-filter to remove dust, filter with activated carbon, and absorb many chemical substances, but ammonia and carbon monoxide need other special filter devices The pre-filter material can be used for an average of 6 months, and the activated carbon la...

Problems solved by technology

[0002] The fume hood without duct ventilation does not require external pipes, does not pollute the external environment, and has little effect on the temperature of the laboratory, but the disadvantage is that the filter material must be replaced regularly, and the experimenter is more likely to be exposed to harmful gases than using an extraction fume hood. Because the extra exhaust fan is very close to the experimenter, it will cause noise. This type of fume hood has the following filtration procedures: use foam plastic pre-filter to remove dust, filter with activated carbon, and absorb many chemical substances, but ammonia and carbon monoxide need other special filter devices The pre-filter material can be used for an average of 6 months, and the activated carbon layer can be used for an average of 2 years. To the atmosphere, this type of fume hood can remove harmful gases in the laboratory more effectively than ductless ventilation, with low noise and simple maintenance. The disadvantage is that a dedicated exhaust duct must be installed, which may hinder the experiment when the indoor and outdoor temperatures are different. The room maintains a constant temperature, and it is unfavorable to environmental sanitation. However, a supplementary air system can be designed. For this type of fume hood, the fan sucks the outdoor air instead of the indoor cooling or heating air, so as to reduce energy consumption and reduce costs. Carbon environmental protection fume hood, also known as fume hood or fume hood, is a large-scale equipment in laboratories, especially chemical laboratories. Primary barrier to protect personnel from the hazards of toxic chemical fumes

It can be used as an important safety back-up equipment, such as when the chemical experiment process fails, and when chemical smoke, dust and toxic gases are produced, it can effectively discharge harmful gases to protect the staff and the laboratory environment. In the prior art, for example, the application number is 201520686440.7 The invention patent includes a bottom bracket, a caster bracket, a tray, and casters. The tray is a T-shaped structure, its upper horizontal structure is connected to the bottom bracket, and its lower vertical structure directly extends to the casters. The tray can be lifted , also includes a tray rubber pad, the tray rubber pad is located between the bottom bracket and the tray, the caster is connected to the bottom bracket through the caster bracket, and the size of the caster wheel can be adjusted. Although the structure of the invention Simple, but there are many deficiencies and defects. In the existing equipment, the design of the tray is flawed, the connection between the tray and the bracket is unstable, and when the angle needs to be adjusted between the tray and the bracket, it needs to be manually adjusted. Adjustment increases the work intensity of the operator, makes the operator feel physically fatigued, and reduces work efficiency. In addition, the bracket lacks a traction device. When moving, the direction of the pallet cannot be grasped, and the operator needs to adjust the travel route frequently. Inconvenience, for these situations, in order to avoid the above-mentioned technical problems, it is necessary to provide a new type of nuclear medicine fume hood activity meter well automatic lifting device to overcome the defects in the prior art
