The new hospital pressure suction system instead of negative pressure vacuum pump -

a, now most of the hospital of negative pressure vacuum water pump application:

80% above current hospital software use of negative pressure system for vacuum pump water ring vacuum pump.

key has the following problems:

1, the water ring vacuum pump must be water cutting fluid, in the operation process, water and breathe in the gas mixture back out and cause water pollution, the pollution of water regulation for wastewater treatment, in accordance with current standards and national industry standards 'water pollutant discharge standard of medical institution' GB18466 related requirements.

2, with a lot of water ring water pump discharged gas disease tableland, if gas water separator is not enclosed, can cause all the fire water pump room of the gas pollution of the environment.

3, vent GB50751 - should be considered The relevant provisions of the 2012 'medical gas engineering technical specifications'

( 1) Surrounding the vent opening area protection, it is forbidden to people through.

( 2) Vent shall be located in the outdoor, and medical equipment gas inlet is located in the same aspect ratio, building Windows, other mouth, and spacing of not less than 3 m;

( 3) Vent gas send out by the monsoon climate, the dangers of engineering and construction, landscape elements and its surrounding, discharged gas cannot be migrated to other workers in work or in the food and clothing live line area.

2, hospital pressure suction system software in detail

1, the external bacteria filter

bacteria type filter is a kind of particle filter, its basic tableland is different size of particles according to the micro chemical fiber filtering material according to the four methods were captured, micro chemical fiber cross section diameter of 0. 5μm- 0. The goal is to filter 75 microns, the key diameter more than 0. 5 microns of bugs.

2, integration of vacuum unit

key features:

( 1) Channel and gateway filtering device.

( 2) After pump temperature kept at 87 degrees, reduce exhaust temperature in 97 - Can be done in 102 degrees, high temperature sterilization effect.

( 3) With dc frequency conversion and intelligent automatic control system, energy saving 30 - than water Above 50%.

( 4) There is no application of cooling water.

this kind of design scheme of another benefit is that, for it has been at high temperature within the cavity of the natural environment, vacuum pipe raw gas absorption into the true lumen is not easy to cold suspected into liquid could cause the destruction of the vacuum chamber or reduce

gas technology according to the British medical equipment professional physical and mental health institutions ( MGPHO) Did a third party, without high temperature ultrafiltration device bacteria filter vent sampling inspection coliform count found less than people at ordinary times the desk or table, and sucked into the raw gas in the vacuum tube ( Such as surgical treatment or hospital beds out of blood and sputum of evaporation gas) Sucked into the true lumen is not easy to cold suspected into liquid tableland bacteria take caused by damage or disease. So hospital negative pressure ultrafiltration device should be installed outside the bacteria filter, high temperature and the operation of the vacuum pump is the key to achieve sterilization effect of vacuum pump source, to achieve the exhaust pipe of the sterility testing purpose.

three, vent sterilizer adopts

to have strict exhaust regulations or of the negative pressure system software upgrading have special requirements, can select the exhaust pipe bacteria filter, the filtering device embedded light hydroxyl ions cleaning equipment, with high toughness broad-spectrum ultraviolet irradiation four provoked caused by low temperature plasma, non-ferrous metal chemicals can hunt bacterial and viral infections, 90% 95% of germs and relativity in blowdown situation more reasonable security immediately.
