Abstract
An instantaneous deactivating system for the exhalated air from SARS patient is composed of a height and direction adjustable sucking hood, air delivering tubes, chemical deactivator, high-temp ultraviolet deactivator, air extractor, and regulator of said sucking hood. Its advantages are simple structure, high effect and high safety.
Description
Technical field
The present invention relates to a kind of instantaneous deactivation of band poison respiratory gas boundling extracting system that is used for the SARS patient.Can collect and retrain that virus in the patient respiration gas spreads and the cross infection that causes in the ward, and have the system of instantaneous deactivation coronavirus.
Background technology
SARS breaks with tremendous force, because we lack understanding to it, preventing and controlling are difficulty quite, and especially the cross infection of SARS isolation ward has caused very big threat to medical personnel, and medical personnel's cross-infection rate is quite high.How to prevent the cross infection of isolation ward, protection medical personnel's life security has become one of most important problem in the SARS control.
Prevent the cross infection of SARS isolation ward, generally adopt the room ventilation of windowing at present, medical personnel wear thick and heavy protective garment work, arrival along with summer, hot weather will make SARS patient and medical personnel's working environment more abominable, to winter, the weather of northern area cold will make isolation ward be difficult to take to window airy way minimizing cross infection.Make the cross infection of anti-SARS in winter difficult more.
Summary of the invention
The purpose of this invention is to provide a kind of instantaneous deactivation of band poison respiratory gas boundling extracting system that is used for the SARS patient.
It has drainage hood, air hose, appendix, chemical ablation device, ultraviolet high-temperature inactivation device, air exhauster and drainage hood adjusting device.
The advantage that the present invention has is simple in structure, easy to operate, inactivation of virus is effective and safe and reliable.Its development and use can prevent the cross infection of SARS isolation ward, and protection medical personnel's life security also can be used at other lazaretto wards.
Description of drawings
Fig. 1 is the instantaneous deactivation system structure of an expiration boundling extracting sketch map;
Fig. 2 is a drainage hood adjusting device structural representation.
The specific embodiment
The instantaneous deactivation of the band poison respiratory gas boundling extracting system that is used for the SARS patient has drainage hood 1, air hose 2, appendix 3, chemical ablation device 4, ultraviolet high-temperature inactivation device 5, air exhauster 6 and drainage hood adjusting device 7 successively.The drainage hood adjusting device has fixed bar 8, elevating lever 9, lock screw 12, positioning screw 11, lateral adjustments bar 10, positioning screw 11, drainage hood 1 successively.Drainage hood 1 can rotate along fulcrum B and A respectively.Drainage hood 1 height can pass through elevating lever 9 up-down adjustment, and 90 ° in cover body air flow inlet direction is adjustable.The cover mouth down is suitable for the prone position patient, and the cover mouth is applicable to the sitting posture patient forward, and cover body is made by transparent material, can observe mutually and exchange between the doctors and patients.
Dress chemical disinfection liquid (peracetic acid etc.) makes air-flow directly contact kill virus with disinfectant solution by suction function in the chemical ablation device, adopts the plural serial stage mode can improve inactivation ratio.Ultraviolet high-temperature inactivation device goes out the poison collection for one with disinfection by ultraviolet light and high temperature, can effectively improve the killing effect of coronavirus.
Form negative pressure in drainage hood 1 inlet D zone during air exhauster 6 work, SARS patient's breathing gas is inhaled in the drainage hood 1 with the head ambient air, air communication is crossed gas pipeline 2 and 3 and is entered chemical ablation device 4 and ultraviolet high-temperature inactivation device 5 successively, carry out the chemical and physical dual virus killing, after killing coronavirus, gas is discharged outdoor by air exhauster 6.
Drainage hood 1 can be done 90 ° of rotations along the point of the A on the lateral adjustments bar 10 clockwise direction, and the cover mouth down is suitable for the prone position patient, and cover mouthful is applicable to the sitting posture patient forward, and cover body is made by transparent material, with make things convenient between the doctors and patients mutual observation with exchange.Lateral adjustments bar 10 can rotate along the B point of elevating lever 9.
When needs with drainage hood 1 when patient's above-head is removed, can laterally push away (or drawing) and open drainage hood 1, this moment elevating lever 9 bottoms in C point position axial rotation, the back that puts in place locks with lock screw, vice versa.Regulate the distance of adjustable in length drainage hood 1 with patient's head of elevating lever 9.
Claims (2)
1. the instantaneous deactivation of band poison respiratory gas boundling extracting system that is used for the SARS patient, it is characterized in that it has drainage hood (1), air hose (2), appendix (3), chemical ablation device (4), ultraviolet high-temperature inactivation device (5), air exhauster (6) and drainage hood adjusting device (7) successively.
2. a kind of instantaneous deactivation of band poison respiratory gas boundling extracting system that is used for the SARS patient according to claim 1 is characterized in that said drainage hood adjusting device (7) has fixed bar (8), elevating lever (9), lock screw (12), positioning screw (11), lateral adjustments bar (10), positioning screw (11), drainage hood (1) successively.
