Abstract
The utility model discloses a ventilation system for an isolation ward, which is characterized in that: comprising an inlet air group and an outlet air group, wherein the inlet air group comprises an inlet fan, an inlet pipe, the wind group comprises an exhaust pipe, an air pump, a filtration unit is included between the exhaust pipe and the air pump, wind rate of the inlet fan is less than that of the air pump. Compared with existing technology, the ventilation system for an isolation ward filters pollution gas in the insolation ward and then discharge the pollution gas into the outdoor space, the spread of bacteria and viruses is avoided, the nosocomial spread is effectively prevented; convection is enhanced, air circulation is highly efficient, and medical personnel safety and health of the body are ensured.
Description
Technical field
The utility model relates to a kind of ward ventilating system, particularly a kind of ventilation system that is applicable to respiratory system communicable disease isolation ward.
Background technology
What infectious respiratory disease was primary will accomplish the blocking propagation approach exactly, and effectively institute's internal resistance section of cutting off the hands is exactly to isolate at present.The single ventilation fan of the many employings of common isolation ward ventilation, but this equipment has the following disadvantages: 1. have only the ventilation function, can not avoid injury fully to human body, and can not carry out filtration treatment at the isolation ward efflux gas, make and contain viral air and directly discharge outdoor, become the pollution sources of air ambient, cause the virus diffusion; 2. adopt positive draft, scavenging efficiency is low; 3. single ventilation fan can not cause convection current to room air, has influenced ventilation effect.
The utility model content
Technical assignment of the present utility model is at above the deficiencies in the prior art, and providing a kind of can filter air, the isolation ward ventilation system that convection efficiency is high.
The technical scheme in the invention for solving the technical problem is: a kind of isolation ward ventilation system, it is characterized in that: comprise air intake group and air-out group, wherein, described air intake group comprises air intake machine, blast pipe, described air-out group comprises exhaust tube, air exhauster, also comprise the filtration unit between described exhaust tube and the air exhauster, described air intake machine air intake rate is less than air exhauster air-out rate.
The blast pipe indoor section of above-mentioned air intake group is installed on the wall of exhaust tube indoor section right opposite highest point, and the exhaust tube indoor section of described air-out group is installed in sick bed side in the ward, is higher than on the wall of sick bed and patient head top.
The blast pipe indoor section pipe end of above-mentioned air intake group has an inclination windscreen.
Above-mentioned filtration unit is a fibrous filter net.
Compared with prior art, the utlity model has following outstanding beneficial effect:
1, drains into the exterior space again after isolation ward internal contamination gas is filtered, avoided the diffusion of bacterial virus, prevented from effectively to send out in the institute;
2, the utility model has been strengthened convection current, and highly effective air circulates, and guarantees the safety and health of medical worker's human body;
3, equipment is simple, and is cheap, is beneficial to popularization.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with specification drawings and specific embodiments the utility model is further specified.
As shown in Figure 1, the utility model comprises air intake group 1 and air-out group 2, wherein, described air intake group 1 comprises air intake machine 3, blast pipe 4, described air-out group 2 comprises exhaust tube 5, air exhauster 6, also comprise between described exhaust tube 5 and the air exhauster 6 filtering unit 7, the filtration unit 7 in the present embodiment is a fibrous filter net, effectively adsorption filtration dust and bacterial virus.Described air intake machine 3 air intake rates rely on barometric gradient to cause air by the circulation of air intake group 1 to air-out group 2 less than air exhauster 6 air-out rates effectively, have guaranteed effective convection current.Dotted line is the signal of circulation of air direction among the figure.
Blast pipe 4 indoor sections of described air intake group 1 are installed on the wall of exhaust tube 5 indoor section right opposite highest points, exhaust tube 5 indoor sections of described air-out group 2 are installed on sick bed 9 sides in the ward, the wall a little more than sick bed 9 and patient head top, the purpose of this design of system is to guarantee flow path direction is helped effectively effluxing of high density pollution air around the sick bed, guarantees that sufferer has a breath of fresh air.
The blast pipe 4 indoor section pipe ends of described air intake group 1 have an inclination windscreen 8, stop the wind that enters directly to blow on one's body the patient.
Need to prove; particular of the present utility model is described in detail the utility model; for a person skilled in the art, in the various conspicuous change of under the situation that does not deviate from spirit and scope of the present utility model it being carried out all within protection domain of the present utility model.
Claims (4)
