Description

The present invention relates to a pathogen infection prevention unit for use in facilities with examination rooms, such as medical facilities and PCR testing facilities, as well as facilities where many elderly people with weakened resistance to disease live, such as geriatric health facilities (nursing care facilities for the elderly) and special nursing homes for the elderly. In particular, the present invention relates to a pathogen infection prevention unit for preventing pathogens generated from patients or test objects from infecting medical workers or handling personnel (hereinafter referred to as medical workers).

Conventionally, various technologies have been proposed to prevent pathogens such as bacteria and viruses carried by patients from infecting medical staff when the medical staff examines the patient in an examination room where the medical staff and the patient are seated facing each other.

Patent Document 1 proposes a stationary medical container that includes an examination room provided inside the container where medical staff treat patients with infectious diseases, an antechamber provided inside the container and separated from the examination room by a door, an examination room door through which either the medical staff or the patient enters the examination room, and an antechamber door through which the other of the medical staff or the patient enters the antechamber, and that is provided so that the traffic line of the one entering through the examination room door is different from the traffic line of the other entering the antechamber, and that when viewed from the partition between the antechamber and the examination room, the antechamber is formed on one end side of the container and the examination room is formed on the other end side, and the antechamber and the examination room are separated in the longitudinal direction inside the container.

Patent No. 6787618

However, the technology described in Patent Document 1 requires an examination room located inside the container where medical staff treat patients with infectious diseases, and an anteroom located inside the container and separated from the examination room by a door, which results in the overall examination room becoming larger.
In addition, the system is equipped with an examination room door through which either the medical worker or the patient enters the examination room, and an antechamber door through which the other of the medical worker and the patient enters the antechamber, and which is arranged so that the traffic flow of one person entering through the examination room door is different from the traffic flow of the other person entering the antechamber.Air is sucked in through an air intake provided in the examination room and flows from the medical worker to the patient, and finally into the negative pressure equipment.As a result, the air sucked in through the air intake collides with the medical worker and the patient, causing turbulence, which causes pathogens generated by the patient to spread and enter the respiratory zone of the medical worker, increasing the risk of airborne infection for the medical worker.
Furthermore, medical staff and patients sit facing each other during examinations, so if the patient coughs or sneezes, there is a risk that droplets will reach the medical staff.

The present invention has been made to solve the above-mentioned problems, and aims to provide a pathogen infection prevention unit that can be installed in facilities that house a large number of elderly people with weakened resistance to disease, such as medical facilities, PCR testing facilities, and other hospital facilities with examination rooms, geriatric health facilities (nursing care facilities for the elderly), and special nursing homes, and can reliably prevent pathogens generated by patients from infecting medical staff.

The present inventors have achieved the above object by the following means.

a fan filter unit 14 for cleaning the air sucked into the return shaft 8 and supplying the clean air to the plenum chamber 6;
This pathogen infection prevention unit is characterized by having an air vent 10 located below the side panel that blows out excess air, which is the amount of clean air blown out into the medical staff area S1 and taken in by the differential pressure maintaining damper 12, into the room in which the infection prevention unit 1 is installed.
[2] A pathogen infection prevention unit as described in [1], characterized in that it is provided with an adjustment mechanism (3A) for adjusting the amount of clean air supplied downward into the patient area (S2) through the punching panel (4).

According to the present invention, the downward airflow speed in the patient side area S2 can be slowed down, so that droplets from the patient within the pathogen infection prevention unit do not travel with aerosols in the air and become disturbed within the patient side area S2, but instead travel with the airflow sucked in from the differential pressure maintaining damper at the patient's feet and are removed by the high-performance filter of the fan filter unit, thereby preventing infection of medical personnel.
In addition, as a means for maintaining positive pressure in the medical staff area S1, the space between the upper plate 1a and the ceiling 3 is used as a plenum chamber 6, and positive pressure is created by blowing air into it from the fan filter unit 14, and a large amount of clean air is blown out from the air outlet 7 in the ceiling 3 of the medical staff area S1, most of which is released from a vent 10 with resistance into the room, such as a hospital room, where the pathogen infection prevention unit is installed.Since the medical staff area S1 can also be kept at positive pressure, it is possible to prevent the intrusion of dust-attached pathogens from the outside or negative pressure areas, including the patient area S2, and safely protect medical staff.
In addition, approximately the same amount of air as that released from the air vent 10 to the outside of the pathogen infection prevention unit is sucked in by the suction force of the fan filter unit 14, a small amount into the patient side area S2 via the differential pressure maintaining damper 12, and a large amount into the return shaft 8 via the differential pressure maintaining damper 12A, so that air can flow into the patient side area S2 while maintaining a slight negative pressure equal to the differential pressure set by the differential pressure maintaining damper 12 from the pressure in the room in which the pathogen infection prevention unit is installed.
Furthermore, comfort can be improved by increasing the speed of airflow in the medical staff area S1.
By making it disassembleable, it can be folded up and stored during normal times when there is no emergency.

FIG. 2 is a cross-sectional view of a pathogen infection prevention unit of the present invention. 2 is a cross-sectional view taken along line AA of FIG. 1.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the accompanying drawings.
Figure 1 is a cross-sectional view of the pathogen infection prevention unit of the present invention, and Figure 2 is a cross-sectional view taken along the line A-A in Figure 1. In this embodiment, the pathogen infection prevention unit is installed and used in facilities where a large number of elderly people with weakened resistance to disease reside, such as hospital facilities with examination rooms, medical facilities, PCR testing facilities, etc., geriatric health facilities (nursing care facilities for the elderly), and special nursing homes for the elderly.

In Figures 1 and 2, 1 is a pathogen infection prevention unit, which is composed of an upper panel 1a and four side panels 1b, 1c, 1d, and 1e. In the figure, 1b is a side panel located behind the medical staff, 1c is a side panel located on the side of the patient, 1d is a side panel provided opposite side panel 1b, and 1e is a side panel provided opposite side panel 1c.

In an embodiment of the present invention, the pathogen infection prevention unit 1 is installed and used on the floor of a room in a hospital facility with examination rooms, such as a medical facility or PCR testing facility, or a facility where a large number of elderly people with weakened resistance to disease live, such as a geriatric health facility (nursing home for the elderly) or special nursing home, and does not have a bottom board, although providing one would make it easier to carry.
Reference numeral 2 denotes a rear wall provided within the pathogen infection prevention unit 1, 3 denotes a ceiling, and 4 denotes a perforated panel. The side panels 1b, 1c, 1e, the rear wall 2, the ceiling 3 and the perforated panel 4 form an examination room S within the pathogen infection prevention unit 1.
Reference numeral 3A denotes an adjustment mechanism for adjusting the amount of air, which is provided on the top plate 3 and consists of a sliding top plate which can move in the direction between side walls 1b and 1d and has a long side equal to the length between side walls 1c and 1e. By moving the top plate left and right in FIG. 1 to vary the ventilation area of the punched panel 4, the amount of clean air supplied to the patient side area S below can be adjusted.

In this embodiment, the punched panel 4 is made of an aluminum plate, but a stainless steel plate or an iron plate may also be used. The plate thickness, hole arrangement, hole diameter, pitch, and aperture ratio are basically designed to provide a greater airflow resistance at the passing speed than the airflow resistance of the air outlet (slit) 7 described below, and can be selected appropriately according to the purpose.

Reference numeral 5 denotes a partition member provided between the medical staff and the patient, and the partition member 5 divides the examination room S into a medical staff area S1 and a patient area S2.
In this embodiment of the present invention, a transparent vinyl curtain is used as the partition member 5, so in order to prevent the partition member 5 from sticking to the inside of the patient area S2 due to the pressure difference between the medical staff area S1 and the patient area S2, a weight is provided at the lower end of the partition member 5, or the lower end of the partition member 5 is fixed using hook-and-loop fasteners or the like to the floor of a facility where many elderly people with reduced resistance to disease live, such as a medical facility or PCR testing facility having an examination room where the pathogen infection prevention unit 1 is installed, a geriatric health facility (nursing home for the elderly) or a special nursing home for the elderly. In order to seal and fix the partition member 5, which is a transparent vinyl curtain, the sides of the partition member 5 are also fixed to the ceiling 3 and side walls 1c, 1e using hook-and-loop fasteners or the like.

In addition, gloves 20 are attached to the partition member 5 in a sealed manner with the opening for the hand on the medical worker area S1 side toward the patient area where the medical worker's hands are positioned when the medical worker sits on the examination chair and examines a patient.
Regarding gloves 20, the gloves 20 may be disinfected and decontaminated when the patient area S2 is disinfected after the patient examination is completed, or gloves 20 may be layered with a different glove 20 for each patient, and gloves 20 may be replaced when the patient area S2 is disinfected after the patient examination is completed.
This allows medical personnel to prevent infection from the patient by examining the patient using the gloves 20.

Numeral 6 denotes a plenum chamber which is formed between the upper plate 1a and the ceiling 3 and the punched panel 4, and which receives the discharge pressure of a fan of a fan filter unit 14 which will be described later.
Reference numeral 7 denotes an air outlet (slit) provided between the ceiling 3 and the side panel 1b, which supplies clean air from the plenum chamber 6 to the medical staff area S1.

Reference numeral 8 denotes a ventilation shaft (air passage) formed between the side panel 1d, which ensures airtightness of the pathogen infection prevention unit, and the rear wall 2 of the examination room S.
Numeral 9 denotes a medical staff entrance/exit provided on the side panel 1b on the back side of the medical staff side, and medical staff enter and exit the medical staff area S1 through the medical staff entrance/exit 9.
In this embodiment of the present invention, since the medical staff area S1 is under positive pressure, a sliding door is used as the medical staff entrance 9, but this is not limited to this and a hinged door may also be used.

Reference numeral 10 denotes an air vent (louver) provided at the medical staff entrance 9 or in the side wall 1b, which exhausts excess air in the medical staff area S1 from the pathogen infection prevention unit 1 into the room in which it is installed.
Reference numeral 11 denotes a patient-side entrance provided in a side wall 1c on the side of the patient area S2, and patients enter and exit the patient area S2 through the patient-side entrance 11.
In this embodiment of the present invention, the patient area S2 is under slightly negative pressure, so a hinged door is used as the patient side entrance/exit 11, but this is not limited to this and a hinged door may be used as the medical staff side entrance/exit.
Reference numeral 12 denotes a differential pressure maintaining damper installed at the patient side entrance/exit 11 on the patient side for the purpose of maintaining the room pressure in a relatively airtight room, and while taking in air A from the room in which the pathogen infection prevention unit 1 is installed into the patient area S2, it makes the internal pressure of the patient area S2 slightly negative by a predetermined differential pressure amount determined from the pressure inside the installation room by the weight of the damper.
A differential pressure maintaining damper 12A that takes in air A from within the room is provided below the return shaft 8, and the internal pressure below the return shaft 8 is made a strong negative pressure by a predetermined differential pressure that can be determined from the pressure within the installation room by the weight of the damper.

Considering the possibility that the pathogen infection prevention unit of this embodiment may be used in an emergency, maintaining the temperature and humidity in the examination room S (medical staff area S1, patient area S2) relies on the comfortable temperature and humidity of the air in the room where the pathogen infection prevention unit is installed.
In this way, the air from the room in which the examination room S is installed is taken in through the differential pressure maintaining damper 12 and the differential pressure maintaining damper 12A, so that an appropriate temperature and humidity environment can be maintained.
Reference numeral 13 denotes an intake port provided at the lower part of the rear wall 2, which draws air B2 possibly containing pathogens from the patient area S2 into the return shaft 8 by the static pressure on the intake side of the fan of the fan filter unit 14.

Reference numeral 14 denotes a fan filter unit equipped with a fan 15 and a HEPA filter 16, which is installed at the entrance of the plenum chamber 6 of the pathogen infection prevention unit 1. It draws in air B2 from the return shaft 8, using the suction force on the suction port side of the fan 15 as a transport force to create the most negative pressure at the upper part of the return shaft 8, filters out solid pathogens that may be present in the air B2 through a high-performance filter 16 on the discharge side of the fan 15, and supplies the air B under pressure into the plenum chamber 6.
The fan 15, which is an electrically operated device, is small and has a simple structure that only requires power supply, and the fan filter unit 14 itself is lightweight. The other components are lightweight panel materials that can be easily removed or folded up with hinges and latches for temporary installation, and everything can be easily assembled and disassembled.

The operation of the pathogen infection prevention unit configured as above will be described in the case where the pathogen infection prevention unit is installed in an examination room of a testing facility.
When the fan filter unit 14 of the pathogen infection prevention unit 1 installed in the examination room of the testing facility is operated, the air A stagnating in the patient area S2 is pushed by the air sucked in from the differential pressure maintaining damper 12 and sucked into the return shaft 8 through the suction port 13 provided in the rear wall 2, and a larger volume of air from the installation room is sucked in from below the return shaft 8 through the differential pressure maintaining damper 12A and mixed and raised as return air. Then, the fan 15 of the fan filter unit 14 sucks in air B2 from the return shaft 8, and the suction force on the suction port side of the fan 15 is used as a conveying force to make the upper part of the return shaft 8 the most negative pressure, and solid pathogens that may be present in the air B2 are filtered and removed through the high-performance filter 16 on the discharge side of the fan 15, and the air is pressurized and supplied into the plenum chamber 6.
In this air flow, air from within the examination room of the testing facility is taken into the patient area S2, which is kept at a predetermined slightly negative pressure from within the installation room due to the differential pressure set by the differential pressure maintaining damper 12.

The majority of the clean air B supplied into the plenum chamber 6 through the high-performance filter 16 is sent from within the plenum chamber 6 toward the side panel 1b, where its direction is changed by the side panel 1b, and the air is supplied to the medical staff area S1 along the side panel 1b from an air outlet (slit) 7 provided between the ceiling 3 and the side panel 1b.
Thereafter, the air B1 that descends while maintaining the positive pressure in the medical staff area S1 is discharged together with the air B11 that remains in the medical staff area S1 from the vent 10 having a ventilation resistance for raising a predetermined positive pressure from the room pressure of the installation room into the room in which the pathogen infection prevention unit 1 is installed. If necessary, it may be discharged outdoors.
This ensures sufficient ventilation on the medical staff area S1 side, which aims to prevent infection while still allowing medical examinations, and also utilizes the Coanda effect at the outlet to blow air at a certain speed down onto the medical staff, providing a feeling of coolness.

In addition, a portion B2 of the clean air supplied into the plenum chamber 6 has its wind speed slowed by the punching panel 4 and is supplied to the patient area S2, and while being entrained in the air A taken into the patient area S2 from the differential pressure maintaining damper 12, is blown out into the return shaft 8 through the exhaust port 13 provided in the rear wall 2.
The air A, which has entrained a portion of the clean air B2, is mixed with the air taken in through the differential pressure maintaining damper 12A located below the return shaft 8, and is raised up as return air. After that, the fan filter unit 14 removes dust, including airborne pathogens, and the air is returned to the plenum chamber 6.
In this way, clean air B2, whose wind speed has been slowed by the punching panel 4, is supplied from above into the patient area S2, so that contaminants such as droplets contained in the breath exhaled from the patient are flowed downward, preventing bacteria from accumulating at the top of the patient area S2, and the contaminants such as droplets are quickly removed by the high-performance filter 16 via the return shaft 8, preventing them from flowing into the medical staff area S1.

Furthermore, most of the clean air B1 from the clean air B in the plenum chamber 6 is supplied to the medical staff area S1, while a portion of the clean air B2 with a slower wind speed is supplied to the patient area S2. The negative pressure is created by the pressure difference with the installation room defined by the differential pressure maintaining damper 12 installed at the patient side entrance/exit 11, so the medical staff area S1 is maintained at a positive pressure relative to the patient side area S2, and the patient side area S2 is maintained at a negative pressure relative to the medical staff area S1, preventing infection of medical staff from pathogens originating from the patient or test subject.

The number of fan filter units 14 to be set is determined based on the size of the infection prevention unit 1 in which the fan filter units 14 are installed, the ventilation rate and circulating air volume in the examination room S.

An example of a method of using the pathogen infection prevention unit configured as described above will be described below, including the overall size, the amount of air required to be supplied within the infection prevention unit, and distribution of the amount of air supplied to each area.
The size of the fan filter unit 14, the number of ventilation cycles in the examination room S, the circulating air volume, etc. are determined according to the purpose. 1) Size of the pathogen infection prevention unit The required size of the pathogen infection prevention unit (W x D x H) was calculated on the assumption that it will accommodate one patient and one medical staff member, as shown in Table 1.

2) Regarding the required air volume for the pathogen infection prevention unit, the ventilation rate and the circulating air volume for each ventilation rate were calculated as shown in Table 2.

As shown in Table 2, the ventilation rate (times/h) is the number of times the air in the pathogen infection prevention unit is ventilated per hour (times/h), and the circulating air volume ( ^m3 /h) is the volume of air circulating (entering and leaving) within the pathogen infection prevention unit per hour corresponding to the ventilation rate.

For example, when the air inside the pathogen infection prevention unit is ventilated 30 times per hour, the corresponding amount of air circulating inside the pathogen infection prevention unit per hour is 160 (m ³ /h).
Furthermore, when the air inside the pathogen infection prevention unit is ventilated 100 times per hour, the corresponding amount of air circulating inside the pathogen infection prevention unit per hour is 510 (m ³ /h).
By ensuring the ventilation rate in this way, the air supplied to the medical staff area from the air outlet (slit) is immediately blown out from the ventilation hole into the installation room, making it easier to maintain a comfortable thermal environment in the medical staff area.

3) An example of the distribution of air volume supplied to each area and the required air volume is shown in Table 3.

The blowing air speeds shown in Table 3 are the air speeds when the clean air B returned from the fan filter unit 14 into the plenum chamber 6 is blown out from the air outlet (slit) 7 into the medical staff area S1 and the air speeds when it is blown out from the punching panel 4 into the patient area S2.

The air outlet size indicates the size of the air outlet 7 that supplies clean air to the medical staff area S1 and the size of the punched panel 4 that supplies clean air to the patient area S2. The air outlet is a long and narrow rectangular slit type measuring 50 mm wide and 1,000 mm long, and the punched panel 4 is configured as a nearly square measuring 1,000 mm wide and 1,100 mm long.
The opening ratio indicates the opening ratio of the air outlet 7 and the punching panel 4 .
The blowing air volume ( ^m3 /h) is the volume of air when the clean air B returned into the plenum chamber 6 is blown out from the outlet 7 to the medical staff area S1, and the volume of air when it is blown out from the punching panel 4 to the patient area S2.
The size of the fan filter unit 14, the number of ventilation cycles in the examination room S, the circulating air volume, the blowing air velocity, the air outlet size, and the opening ratio and air volume are appropriately selected according to the purpose.
