Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a clean air blowing device for the purpose of supplying sterile air to patients with leukemia, burn injuries, or other conditions where bacterial infection may worsen the condition.

(Prior art) For example, it is said that the mortality rate of patients with leukemia is largely due to bacterial infection, and for this reason, as a means of isolation treatment, patients are housed individually in clean booths, etc., regardless of the severity of their illness or mild symptoms. Treatment is performed in an isolated state, and the clean booth is, for example,
The one described in Publication No. 181167 is disclosed. As shown in Fig. 3, the clean booth has an actuator housing b erected on the head side of a bedded patient on a bed a, and an air blowing chamber c protruding from the top of the housing b to cover the bed. Then, clean air was blown downward from the bottom surface of the bed, and supports d were erected on both sides of the foot side of bed a, and these were used to surround three sides of bed a, the foot side and both sides, with a vinyl membrane e. It is something.

(Problems to be solved by the invention) In the conventional so-called clean booth described above, an actuator case is installed on the head side of the bed on which the patient lies, the top surface of the bed is covered with an air blowing chamber, and the foot and both sides of the bed are covered with an air blowing chamber. Because the clean booth is surrounded by a vinyl membrane, it gives a feeling of intimidation to the patient and causes a great deal of mental pain due to being confined in a small space, which places a heavy burden on patients with mild symptoms. Because of the large size of the equipment, even if it is a mobile type, it not only takes time and effort to install and remove the equipment, but also requires a specialist to do the work.Furthermore, the equipment occupies a considerable area, so it is necessary to prepare the environment at the installation location. Furthermore, since the work equipment is located near the patient's bedside, there are disadvantages such as the noise caused by the blower and the like.

(Means for Solving the Problems) The present invention eliminates the above-mentioned conventional inconveniences, and eliminates the conventional booth type that covers the entire circumference of the bed, especially for patients with mild leukemia, and improves the patient's breathing. Provided is a clean air blowing device that is an open type that blows clean air horizontally, targeting only the area affected by the disease, which alleviates mental pain for patients, and which can be easily removed like equipment. The actuator case has an air intake port on the front and is equipped with a blower mechanism inside and is positioned horizontally on the floor. The air blowing chamber is set up in an L shape,
The present invention is characterized in that a large number of ventilation holes for horizontally blowing out air are arranged on the inner surface of the air blowing chamber, and a moving wheel is provided on the lower surface of the actuator housing.

(Function) The clean air blowing unit according to the present invention has the following features:
When the unit is lying on the bed, the L-shaped horizontal actuator case is located on the bottom surface of the bed, and the upright air blowing chamber is positioned on one side of the bed so as to protrude from the top surface of the bed. The device is placed stationary in a position biased toward the patient's head, and the air blown out from the air outlet of the air blowing chamber flows as a horizontal laminar flow, ensuring cleanliness in the area that affects the patient's breathing. In addition to increasing the amount of bacteria, it also prevents and treats bacterial invasion and infection. Since the unit is movable by means of wheels at the bottom, it can be freely moved and adjusted to an appropriate position relative to the patient.
It is also possible to freely carry it into and out of the facility location. In addition, since the air blowing range is within the range that affects the patient's breathing, a weak wind is sufficient, and the blower is small and rotates at a low speed.Furthermore, the actuator housing equipped with the blower is located under the bed, so it does not make noise. This can prevent damage caused by

This device is an open type without using vinyl curtains like the booth type, so it does not cause mental pain to the patient due to a feeling of isolation. If there is a risk that the cleanliness of the area may deteriorate, by shielding the limited area with curtains, etc., it is possible to prevent the intrusion of bacteria, etc. and ensure a highly clean environment.

(Example) Embodiments of the present invention will be described with reference to the drawings.

In the drawing, A is a blower unit, and this unit A has an air intake 4 on the front side to suck in ambient air, an actuator case 1 equipped with a blower 5 and a temperature controller as necessary, and a rear blower. It consists of a clean air blowing chamber 3 that communicates with the air side through a wind guide duct 2, and the actuator housing 1 is positioned horizontally on the floor, and the clean air blowing chamber 3 is L-shaped as a whole so that it is vertically oriented. It consists of
If the case of unit A is molded from aluminum, it will be easier to handle.

A large number of ventilation holes 6 are provided on the entire front surface of the clean air blowing chamber 3 in an evenly distributed arrangement to blow air evenly, and a filter 7 and a germicidal lamp 8 are provided in the chamber 3 if necessary.

The blower 5 installed in the actuator case 1 is of a continuously variable speed type and can be controlled automatically or manually. Casters 9 are provided on the lower surface of the actuator case 1 to make the unit A movable. It is convenient to move and transport the unit A by providing a transfer handle 10 at a suitable location such as on the rear surface of the unit A.

As shown in FIGS. 1 and 2, the unit A has the actuator housing 1 installed on the underside of the bed a, which is located toward the bedside patient's pillow. Therefore, the air blowing chamber 3 of the unit A is Clean air is projected from the bed surface on one side of the bed a, and clean air is blown out horizontally from the ventilation holes 6 on the head side of the bedded patient, and if necessary, a shielding membrane 11 such as a vinyl curtain is installed to isolate the blowing area. The unit A can be freely carried in and out from one side of the bed a at any time.

(Effects of the invention) The present invention targets patients with relatively mild leukemia or burn injuries, and unlike the conventional isolation booth type, it is an open type and can be freely combined with a bed, making it easy to use. It is convenient and does not cause mental pain to patients due to isolation.It is small so it occupies a small area and does not cause any inconvenience to other medical equipment when moving it.The range of clean air blowing out affects the patient's breathing. Since the area is a small area, the amount of air blown is small, so the fan is small and operates at low speed, and since the fan is located under the bed, it has the effect of not causing harmful noise to the patient. Another advantage is that leukemia patients can be allowed to live with general patients.
