Window Tents

In the treatment of tuberculosis the window tent was originally devised to give fresh air to patients in their own rooms. To a poor family the window tent has an economic advantage, especially if the room where the patient lies serves as a living room for the rest of the family. The fact that the well members should not shiver is of vital importance in many respects. A simple home window tent, and one which can be made easily in the homes of the poor, consists of a straight piece of denim or canvas hung from the top of the window casing and attached to the outer side of the bed. The space between this and the window casing on each side is closed with the same material properly cut and fitted. Ten to twelve yards of cloth is necessary. If made of denim, the price of the tent would be about $3.00; if of canvas, about $4.50. If this cannot be obtained, take two large, heavy cotton sheets, sew them together along the edge, tack one end to the top of the window casing and fasten the other end to the bed rail with tape. There will be enough cloth hanging on each side to form the sides of the tent, and this should be tacked to the window casings. The manufactured window tents are all constructed practically on the same principle. The difference between them is in their shape and the manner of their operation. There are two types: the awning variety, as illustrated by the Knopf and the Allen tents; and those of the box order, of which the Farlin, Walsh, Mott and Aerarium are examples.

Knopf Window Tent. The Knopf window tent[1] is constructed of four Bessemer rods furnished with hinged terminals, the hinges operating on a stout hinge pin at each end with circular washers so that it can be folded easily. The frame is covered with yacht sail twill. The ends of the cover are extended so they can be tucked in around the bedding. The tent fills half of the window opening and can be attached to the side casings three inches below the center of the sash, this space being for ventilation. The patient enters the bed and then the tent is lowered over him, or he can lower the tent himself by means of a small pulley attached to the upper portion of the window. The bed can be placed by the window to suit the patient's preference for sleeping on his right or left side. A piece of transparent celluloid is inserted in the middle of the inner side so that the patient can look into the room or can be watched.

Allen Window Tent. The Allen window tent[2] is on the same order as Knopf's, the difference being chiefly in size. The

Allen tent covers the entire window and has the appearance of an ordinary window awning turned into the room, ventilation being secured from openings above the upper and below the lower sash.

Box Window Tent. The box variety of window tent consists of a light steel frame covered with canvas or cloth. The frame fits between the window casing like a wire screen frame. The bottom, through which the head is passed, can be made of flannel and can be drawn closely around the neck.

Aerarium. Dr. Bull's aerarium[3] is another device similar to a window tent. This arrangement consists of a double awning supported on a wooden or steel frame and attached to the outside of the window with a special ventilating arrangement. The head of a cot bed is put through the window and the patient's head rests out of doors. The lower window sash must be raised about two feet and a heavy cloth or curtain hung from its lower edge so that it will drop across the body and shut off the room from the outside air.

Window tents have a few advantages. The patient's prolonged rest in bed will be more endurable when he is permitted to look out on the street and watch life than when obliged to gaze at the four walls of his room. Also patients, who can be persuaded only with difficulty to sleep with the window wide open, will not hesitate when they have this tent as an inducement. Draft which the patient usually dreads, particularly in cold weather and when he perspires, need not be feared when sleeping in a window tent. Further, this limits the possible infection to the interior of the window tent, which is obviously an advantage. While, as a matter of course, the patient will have been taught to always hold his napkin before his mouth when he coughs or sneezes, this is not always done, and cannot be done when coughing in sleep. The constant exposure to air and light of the bacilli, which may have been expelled with the saliva and remain adhered to the canvas, will soon destroy them. Also the canvas of the tent is attached to the frame by simple bands and its removal from the frame for thorough cleansing, washing and disinfection is thus made easy.
