Abstract
The present invention relates to a vacuum treatment generator used in medical biochemical analysis instruments, which belongs to an electromechanical integration system. The vacuum treatment generator comprises a housing 2-1, a pressure sensing connecting pipe 2-2, a vacuum pump 2-3, a pressure sensor 2-4, an air inlet pipe 2-5, a screw 2-6, a bracket 2-7, a sealing plug 2-8, an end board 2-9, a liquid level sensor 2-10, a vacuum chamber cylinder 2-11, a partition board 2-12 and a rear sealing plug 2-13. The present invention has the advantages that the liquid level sensor for detecting the liquid level is adopted, and the mode for relatively raising a vacuum chamber body by using the partition board is used to achieve the goals of controlling the liquid level in the vacuum chamber body, increasing the useful space and effectively protecting the vacuum pump. The present invention provides a vacuum treatment generator which can give an alarm and can increase the useful space. The present invention becomes an indispensable instrument for diagnosing illnesses of patients in large and medium-sized hospitals, can be used in large medical biochemical analysis instruments, and can be used in bioengineering, pharmaceutical engineering and other fields.
Description
Technical field:
The invention belongs to electro-mechanical system, relate to the vacuum generating device that uses on the medical biochemical analyzer.
Background technology:
Large-scale medical biochemical analyzer becomes the imperative equipment that big-and-middle-sized hospital diagnoses conditions of patients, for removing vapour, handles the more accurate medical distilled water that micro syringe need be used of the result who makes measurement, basic skills is with the gas sucking-off in the water that flowing in the liquid road, and this just needs a vacuum generating device; The solution of original technology as shown in Figure 1, it is made up of shell (1), pressure sensing connecting leg (2), vacuum pump (3), pressure transducer (4), draft tube (5), screw (6), vacuum cavity (7), sealing-plug (8).Detailed content of the present invention: when working for solving device, easily water is brought in the vacuum cavity, when liquid level rises to certain altitude, vacuum pump can suck water problems such as causing fault in the pump housing, the purpose of this invention is to provide a kind of application of vacuum generator that can report to the police and can improve the useful space.
Of the present invention basic composition is: as shown in Figure 2: form by shell, pressure sensing connecting leg, vacuum pump, pressure transducer, draft tube, screw, support, sealing-plug, end plate, liquid level sensor, vacuum chamber tube, dividing plate, back sealing-plug, mutual relationship between each parts is to make circular hole in the center of dividing plate, and two boss punishment that two dividing plates are separately fixed at vacuum chamber tube endoporus is slit into cavity, the two ends that two end plates is separately fixed at the vacuum chamber tube form assembly a; Fixed in position has liquid level sensor and draft tube to form assembly b in sealing-plug, then assembly b is inserted in the hole on the vacuum chamber tube top among the assembly a, assembly a respectively with support and bright fixedlying connected outward; Back sealing-plug is inserted in another hole on the vacuum chamber tube top among the assembly a.
Its basic functional principle is to open when making work when system, with the water of bringing in the vacuum cavity, when the liquid of one of them cavity rises to the circular hole of dividing plate, liquid flows to second cavity, and when the liquid in second cavity rose to the circular hole of dividing plate, liquid flowed to the 3rd cavity, liquid in the 3rd cavity rises to certain position constantly, liquid is contacted with contact below the liquid level sensor, and alerting signal is sent in the liquid level sensor conducting.
Advantage of the present invention is to adopt the liquid level sensor detection of liquid level; use dividing plate that the vacuum chamber tube is divided into a plurality of cavitys; improved the mode of vacuum cavity relatively; reach liquid level in the control vacuum cavity; improve usage space, effectively protect the purpose of vacuum pump, a kind of vacuum generating device that can report to the police and can improve the useful space is provided.The present invention can be used for large-scale medical biochemical analyzer becomes the imperative equipment that big-and-middle-sized hospital diagnoses conditions of patients, also can be used for aspects such as bioengineering, pharmaceutical engineering.
