Description

Infectious disease is isolated the sick bed air exhausting device

Affiliated field

The utility model relates to a kind of ward equipment.

Technical background

At present, severe acute respiratory syndrome is just threatening our country and the people of the world's life with healthy; Infect for the medical personnel that prevent a line, good ventilation has become effective experience; Therefore, a large amount of ventilating fans are put into the ward; And the air-conditioning quilt forbidding; Because, easily make virus be evenly distributed on whole ward, serious harm patient and medical personnel's health if use air-conditioning to be unfavorable for virus dilution at confined space; If at the open space of a large amount of ventilations, air-conditioning is also with ineffective; Yet along with the sweltering heat gradually of weather, tight protective garment and nervous hard work make medical personnel face severe difficulty.

Summary of the invention

The purpose of this utility model is: a kind of simple, practical and exhaust ventilator of being easy to make is provided, with less capacity, may contains the air discharge of a large amount of viruses, make air-conditioning to be used.

For realizing this purpose, the scheme that the utility model is taked is: a kind of infectious disease is isolated the sick bed air exhausting device, is made up of head of a bed fan housing and bed body fan housing; Be provided with the fan exhaust passage in the head of a bed fan housing, the fan exhaust passway can be installed fan or is connected with the passage of gas extraction system; Bed body fan housing and head of a bed fan housing can surround sick bed together, and sick bed is on the bleeding point of whole air exhausting device, the long and narrow seam of bleeding of the final formation in the edge of the edge of sick bed and two fan housings.

Bed body fan housing is made of bed left side coaming plate, the right coaming plate of bed and cabinet base coaming plate, and left and right sides coaming plate can be hinged on the bedstead.

Perhaps bed body fan housing is made by airtight membranaceous material or coated fabric, and the time spent can center on and be fixed on around the bed.

Because by a head of a bed fan housing and an air exhausting device that the body fan housing is formed, can together sick bed be surrounded, sick bed is on the bleeding point of whole air exhausting device, the long and narrow seam of bleeding of the final formation in the edge of the edge of sick bed and two fan housings can be discharged outdoor with short path the high concentration poison atmosphere that patient on the bed may distribute with less capacity; Even medical personnel closely near patient, still can be in its weather, reduced infected risk; Under this environment, as long as frequent cleaning and sterilizing should use air-conditioner.

Since the left and right sides coaming plate of bed body fan housing can be hinged with bedstead on, so patient's articles for use can put into the duct space under the bed easily and safely, have further reduced air pollution.

Because bed body fan housing is made by airtight membranaceous material or coated fabric, the time spent can center on and be fixed on around the bed, and handling ease is with low cost, uses flexibly.

The specific embodiment

Below in conjunction with accompanying drawing enforcement of the present utility model is described further.

As shown in Figure 1, form by head of a bed fan housing 11 and bed body fan housing 13 two parts; Be provided with fan exhaust passage 12 in the head of a bed fan housing; Head of a bed fan housing and forms fan housing lump together and have constituted sick bed air exhausting device 14; This air exhausting device has just formed the long and narrow seam 16 of bleeding if sick bed 15 is trapped among the inside at the edge of sick bed; As shown in Figure 2, in head of a bed fan housing 21, fan exhaust passage 22 is arranged, and be provided with some supporting constructions 23 in order to support panel 25; Can establish transom window with cover 26 on the panel, transom window is opened the back air-flow and can be passed through from transom window mouth 27; Adjustable shutter can certainly be set; The uviol lamp 24 of killing microorganisms can also be installed in head of a bed fan housing; As shown in Figure 3, the panel that has transom window 32 is installed on the supporting construction 31 of head of a bed fan housing, forms the vertical air-breathing slit 33 around the head of a bed around, and device still can play a role when patient's seat; When patient's clinostatism or when carrying out operation such as intubate, the cover plate 38 of transom window 32 can be opened, open transom window 39 and strengthen bleeding; Preferably use can speed governing fan; The bed surface 34 of sick bed and bed body fan housing 35 have constituted the air-breathing slit 36 of level; Air-breathing slit can not be established at the position 37 of cabinet base; The biside plate 310 of bed body fan housing is hinged on bedstead or device, can open when needing, and patient day's articles for use 312 are left in the bed air intake passage 311 down, and minimizing is to the pollution of air; As shown in Figure 4, the side plate of bed body fan housing can be made by metal, plastics or timber and fibrous material; When the lower material of working strength, low-intensity material 43 can be engaged use with metal hinge spare 45; Hinge spare is provided with hinge hole 44; Side plate is connected with the connector 410 that is fixed in advance on the bedstead by hinge hole 411; Cabinet base baffle plate 49 adds that by fixing hole 48 grades and bed hole 46 grades of accomplishing fluently in advance are connected and fixed; When the stronger exhaust effect of needs, can use higher baffle plate, and connector is fixed on higher position 47 in advance; The device overall schematic that Fig. 5 adopts this method to make; Fig. 6 is to use the principle generalized section, and when needs passed through 64 air drafts of ward window, it is higher that fan exhaust passage 65 positions of head of a bed fan housing should be designed; Fan 66 will be sent to outside window from the air-flow 61 of the air-breathing slit in bed both sides with from the air-flow 63 of head of a bed fan housing slit and from the air-flow 62 of transom window; In the time can't utilizing the window air draft, or when inconvenient, can on wall 67, punch, and make its position corresponding with exhaust passage 68 by the window air draft.
