Abstract

The utility model relates to a negative pressure disinfecting hospital bed. A frame is arranged at the peripheral portion of the hospital bed body, and partition boards are fixed on the frame to build an isolation cover. An opening door is arranged on one side of the partition boards of the isolation cover, and a blast tube and an exhaust tube are also arranged on the isolation cover. The blast inlet of the blast tube and the exhaust outlet of the exhaust tube are arranged at the inner side of the isolation cover. The outlet of the exhaust tube is connected with the inlet of an ozone and chlorine dioxide binary sterilizing machine. The outlet of the binary sterilizing machine is connected with an air extractor. Negative pressure is formed in the isolation cover of the hospital bed and the exhaust gas is exhausted by the function of the negative pressure of the air extractor after the disinfecting of the binary sterilizing machine. The exhaust gas can be disinfected in time by using the utility model. At the same time, the input fresh air for the patient is also disinfected. The concentrations the bacteria and virus are reduced, the spreading of the cross infection is prevented, the survival times of bacteria and virus after leaving the human bodies are shorten, the source of infection is sufficiently isolated and disinfected and the spreading of the contagious sickness is prevented. The negative pressure disinfecting hospital bed has simple structure and strong practicability.

Description

Negative pressure sterilization sick bed

Technical field

This utility model relates to a kind of sterilization sick bed, and after especially a kind of waste gas that the patient is discharged carried out disinfection, the negative pressure sterilization sick bed of row discharging belonged to armarium manufacturing technology field again.

Background technology

Infectious disease, especially the communicate illness of some respiratory tracts, modal circulation way is exactly that the pathogenic bacterium, the virus that cause this kind infectious disease are propagated by flow air, viruses of once propagating on a large scale such as atypical pneumonia particularly, its infectiousness, vitality are extremely strong, must carry out strict isolating and protecting for the infectious disease of this character, ward off disease and propagate to other people.

Existing isolation way in the present various big hospital, normally the patient is taked quarantine measures, such as: adopt modes such as lesion isolation, ward isolation with between patient and the patient, isolate between patient and the non-patient, carry out isolating and protecting between mode such as medical personnel then take to dress protective clothes, wear glove in treatment work, mask isolation and the patient.Though this mode has certain isolation effect, but when disease has stronger infectiousness, and pathogenic bacteria, virus can be infected by number of ways, when causing disease patient of the same race to roll up, this traditional isolation method often can not play good effect.

In the existing common isolation ward, have an above patient usually and in same ward, accept hospitalization, different patients' admission time difference, the treatment cycle difference, virus of carrying and patient can distinguish to some extent to other people infectivity.In strict accordance with patient's severe extent and infection ability size and to distinguishing their lesion, obviously less feasible.And this mixing treatment will inevitably cause the cross infection between the patient, even the patient that can cause the state of an illness to alleviate is infected again by the severe patient.Simultaneously, also easy health to medical personnel threatens.

Therefore, the waste gas that the patient discharges is handled timely, just seemed particularly important.Simultaneously, the new wind of importing for the patient also should carry out disinfection, reduce the concentration of pathogenic bacteria in the air, virus, prevent the cross infection and the propagation of pathogenic bacteria, virus, shorten pathogenic bacteria, the time-to-live of virus after leaving human body, to the source of infection fully, isolate completely and sterilize, prevent spreading of infectious disease, particularly prevent to have extremely strong vitality and infection ability, spreading of the disease that can propagate by air is a problem demanding prompt solution.

The utility model content

Technical problem to be solved in the utility model is at the deficiencies in the prior art, a kind of negative pressure sterilization sick bed is provided, when the waste gas that the patient is discharged is in time disinfected, the new wind of importing for the patient also carries out disinfection, reduce pathogenic bacteria in the air, the concentration of virus, prevent pathogenic bacteria, the cross infection and the propagation of virus, shorten pathogenic bacteria, the time-to-live of virus after leaving human body, abundant to the source of infection, isolate completely and sterilize, prevent spreading of infectious disease, particularly prevented to have extremely strong vitality and infection ability, the spreading of the disease that can propagate by air, simple in structure, practical.

The technical problem that this utility model solved is achieved by the following technical solution:

A kind of negative pressure sterilization sick bed, which comprises at least sick bed, sick bed bed body periphery has set up framework, stationary barrier on the framework, set up the isolation cover that becomes to be used for spatial separation beyond patient and the sick bed, offer on the one side dividing plate of isolation cover and be used for opening the door for patient's discrepancy and medical personnel's treatment, be installed with ajutage and exhaust duct on the isolation cover, the air outlet of ajutage and the exhaust outlet of exhaust duct all are opened in the inboard of isolation cover, described exhaust duct outlet and ozone, the inlet of chlorine dioxide binary sterilizing machine links to each other, the outlet of binary sterilizing machine links to each other with air exhauster, make and form negative pressure in the sick bed isolation cover, the waste gas that the patient discharges is discharged under the suction function of air exhauster after by the disinfective action of binary sterilizing machine.

Between binary sterilizing machine and the air exhauster, also be provided with defecator,, after the defecator filtration, under the suction function of air exhauster, discharge again by the waste gas after the sterilization of binary sterilizing machine.

The binary sterilizing machine is the closed cabin body, be provided with binary gas generator, gas mixer, physical reaction device and aerosol atomizer in the body of cabin, electrolysis produces in the binary gas generator ozone and chlorine dioxide mix in gas mixer, and the generation physical reaction forms the binary disinfectant solution in the physical reaction device, and by aerosol atomizer with binary disinfectant solution atomizing, waste gas is carried out disinfection.

The defecator that is arranged between binary sterilizing machine and the air exhauster can be activated carbon adsorption purifier or molecular sieve filtration purifier.

One end of ajutage is connected with the new wind outlet of special-purpose air purifier.

The sick bed upward-acting door offer the position in the sick bed head of a bed one side so that patient accepts nursing, treatment and bunk bed activity.

Air outlet and exhaust outlet are separately positioned on the both ends of sick bed, and make air outlet square on the upper side in patient head, and exhaust outlet is square on the lower side in patient foot.

In sum, this negative pressure sterilization sick bed provided by the utility model, when the waste gas that the patient is discharged is in time disinfected, the new wind of importing for the patient also carries out disinfection, reduce pathogenic bacteria in the air, the concentration of virus, prevent pathogenic bacteria, the cross infection and the propagation of virus, shorten pathogenic bacteria, the time-to-live of virus after leaving human body, abundant to the source of infection, isolate completely and sterilize, prevent spreading of infectious disease, particularly prevented to have extremely strong vitality and infection ability, the spreading of the disease that can propagate by air, simple in structure, practical.
