More specifically, it includes a housing in which an open surface is formed in the center and a flow path for air to flow along the edge is formed; A filter unit that purifies the air sucked into the flow path; It includes a lower fan that sucks air into the housing and flows it along the flow path, and includes a droplet blocking device that can block the spread of droplets by creating a descending airflow so that the air moves along the flow path and closes the open surface. It's about.

In general, infectious diseases such as the recently prevalent coronavirus, MERS, and SARS are transmitted through the respiratory tract, so it is not easy to predict the transmission route, and they spread quickly and require immediate isolation.

In particular, coronaviruses are viruses that can infect different species, including the SARS coronavirus, which causes severe acute respiratory syndrome that spread worldwide in 2003, and the MERS coronavirus, which spread and spread domestically in 2015. . These coronaviruses are all known to have originated from bats. In addition, the new coronavirus (2019-nCoV), which recently broke out in Wuhan, China and is spreading worldwide, was confirmed to be a heterogeneous infection.

As seen in the great confusion caused by pandemics such as the coronavirus or MERS virus, when the coronavirus is infected and spread to humans, it is difficult to block its spread early, so the social impact and confusion are very large.

In addition, most of the confirmed coronavirus cases are patients, medical staff, or visitors hospitalized in hospitals where the infected person received treatment or examination, and are classified as hospital-acquired infections rather than infections caused by external contact. Therefore, measures to block the infection route within the hospital are urgently needed. This is the situation.

However, in conventional screening clinics, privacy protection for test subjects was insufficient, making it difficult to actively encourage test subjects to receive treatment. In addition, treatment boxes installed as temporary tents or simple panels raised the risk of spreading pathogens between test subjects or between test subjects and examinees. In addition, the problem was raised that it is difficult for conventional mobile clinics installed outdoors to provide a comfortable indoor environment for testers and testees in climates such as summer and winter.

When the tester and the testee communicate face-to-face, droplets are unconsciously secreted as the testee speaks and spread within the space where the testee is present.

To prevent this, a shield made of transparent acrylic is placed between the tester and the subject, and the transmission of droplets can be blocked through the shield.

However, during the consultation between the examiner and the examinee, much of the sound was blocked by the screen, so they often raised their voices or asked questions again, causing discomfort in conversation.

Accordingly, although a plurality of holes were drilled in a portion of the screen to facilitate the transmission of sound, there is still a problem in that it is insufficient for the sound to be clearly transmitted through the plurality of holes.

In addition, a microphone was installed on the counselor's side and a speaker was installed on the counselee's side to facilitate sound transmission, but this only facilitated the transmission of sound in one direction, and it was still difficult for the counselor to hear the counselee's words.

Medical staff, who are counselors, come into contact with numerous patients during the day and conduct consultations, and because some of the people being consulted include those suspected of being diagnosed with the disease, the risk of exposure to infectious diseases is very high.

In addition, when a person being tested is diagnosed as a confirmed infectious disease from a suspected infectious disease, tracking and management of medical staff or visitors who have been in contact with the infected person is required, but it is limited to frequently check the visit status of medical staff or visitors who visited each patient.

Therefore, when medical treatment is provided between a counselor and a counselee, the development of a device that provides a safe counseling space where both the medical staff and the counselee can escape the risk of infectious diseases and allows smooth communication is on the rise.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings so that those skilled in the art can easily implement them.

In the present invention, the front refers to the direction in which the patient is located, and the rear refers to the direction in which the medical staff is located. Therefore, the patient on the front side and the medical staff on the back side face each other with the present invention in between.

As shown in Figures 1 to 9, the droplet blocking device according to the present invention is a device placed between people facing each other to block droplets to prevent the spread of infectious diseases,

It consists of a front housing 110 and a rear housing 120, and an open surface 130 is formed in the center, and a downward outlet 170 through which air is discharged is formed on the upper part of the open surface 130, and the surrounding An intake port 180 through which air flows is formed in the lower part of the open surface 130, a filter receiving part 140 is formed in the lower part of the intake port 180, and a horizontal filter receiving part 140 is formed in the lower part of the filter receiving part 140. A lower hollow part 150, which is a space having a length in the direction, is formed, and an upper hollow part 160, which is a space having a length in the horizontal direction, is formed at the upper part of the lowering outlet 170, and the housing 100 A flow path 300 through which air flows along the edge is formed inside, and the air flowing through the flow path 300 is discharged from the descending outlet 170 and flows down to the surface covering the open surface 130. A housing 100 forming a;

A filter unit 500 disposed in the filter receiving unit 140 and purifying air flowing into the housing 100 through the intake port 180;

It is disposed in the lower hollow part 150, sucks air into the interior of the housing 100 through the intake port 180, and discharges air toward both sides from the lower hollow part 150, so that the air flows into the flow path ( It includes a lower fan 600 flowing along 300).

The droplet blocking device according to the present invention is a device for blocking droplets from being transmitted to the other party during consultation between a medical staff member and a patient when receiving treatment face-to-face.

Patients who visit medical staff while sick due to an infectious disease or other disease have a high probability of being suspected of being potentially infected. When visiting a medical staff while carrying infectious bacteria, there is a high probability that the patient's infectious bacteria will be transmitted to the medical staff through droplets during the treatment and consultation. The spread of infectious diseases may increase as medical staff treat multiple patients while infectious bacteria are transmitted to medical staff.

Therefore, the present invention is placed between the medical staff and the patient to prevent droplets from reaching the other party, thereby removing infectious bacteria contained in the droplets and preventing the spread of infectious diseases.

The purpose of the present invention can be achieved by forming a virtual wall between the medical staff and the patient using air flow and preventing droplets from passing through the virtual wall.

As a means to achieve the purpose of the present invention, the present invention is provided with a housing 100 in which an open surface 130 is formed in the center and a flow path 300, which is a passage for air to pass through, is formed at the edge.

Communication between medical staff and patients occurs through the open surface 130, and air is discharged from the top of the open surface 130 downward to block droplets. Therefore, as the air is discharged, it blocks droplets and germs from passing through the open surface 130 and is absorbed into the lower part of the housing 100.

A filter unit 500 is disposed at the lower part of the housing 100, and a lower fan 600 is provided at the lower part of the filter unit 500 to generate air flow.

As the lower fan 600 rotates, surrounding air is sucked in through the intake port 180 of the housing 100, and as the sucked air passes through the filter unit 500, harmful components such as viruses and bacteria are collected and purified. .

The air purified through the filter unit 500 receives the flow force generated by the lower fan 600 and moves along the flow path 300 formed inside the housing 100. The air moves along the flow path 300 and reaches the descending outlet 170 formed at the top of the open surface 130, and is discharged downward from the descending outlet 170, thereby closing the open surface 130. will be.

As air is continuously circulated and discharged and sucked in, the open surface 130 can be maintained in a sealed state by the air current formed by the air.

Therefore, the open surface 130 is not physically sealed but is sealed by a descending air current, thereby ensuring smooth communication between medical staff and patients and preventing the spread of infectious diseases by allowing droplets to be swept away and settled by the downward air current. You can block it.

As shown in Figures 1 to 9, the housing 100 according to the present invention is placed between the medical staff and the patient to enable communication, and forms a flow of air to block droplets, viruses, bacteria, etc. through downward airflow. It is a composition that does.

As shown in Figures 3 and 4, the housing 100 has a large open surface 130 formed at the center. The open surface 130 occupies most of the area of the housing 100.

Through the open surface 130, medical staff and patients can communicate, and droplets trying to pass through the open surface 130 can be blocked by sinking.

The location of the open surface 130 is preferably located at the eye level of the medical staff and the patient. Since droplets are discharged from the oral cavity and spread, in order to block these droplets, it is better to position the open surface 130 at eye level so that as many droplets as possible face the open surface 130.

The open surface 130 is a surface where a downward airflow is formed. Since it is not physically sealed because it is not equipped with a solid structure such as a valve, communication between medical staff and patients is possible, and medical work such as treatment and consultation can be carried out. You can.

Since the open surface 130 is sealed by the flow of fluid caused by a downward air current, droplets trying to pass through the open surface 130 are blocked by the fluid and sink downward according to the flow of the fluid. Therefore, harmful components such as droplets and viruses are blocked without passing through the open surface 130, thereby preventing droplets from being transmitted between medical staff and patients.

As shown in FIG. 7, a flow path 300 through which air can move along the edge of the housing 100 is formed inside the housing 100. As air flows inside the housing 100 outside the edge of the open surface 130, a downward airflow for sealing the open surface 130 is continuously formed.

That is, the housing 100 forms an open surface 130 in the center and has the external shape of the present invention, and has a frame structure for forming an air flow path 300 at the edge of the open surface 130. It is provided.

The housing 100 may be formed of expanded styrene resin material (brand name: Styrofoam). The expanded styrene resin material has a low density, is light in weight, and absorbs almost no water, so it is not damaged by bacteria or mold. Therefore, since the present invention is mainly used in medical settings, it is hygienic by preventing the propagation of viruses, bacteria, etc.

In addition, by taking advantage of its light weight characteristics, the droplet blocking device of the present invention is mounted on a stand 10 with wheels as shown in Figure 9(a), so that it can be placed in an appropriate position according to the conditions and environment of the place where it is placed. It is easy to move, making it easy to place between medical staff and patients. In addition, since the housing 100 can be easily moved during medical treatment in the process of examination between the medical staff and the patient in close proximity, it is possible to perform medical treatment while sharing or separating the space between the medical staff and the patient.

Even if a medical staff member or patient moves closer and holds the housing 100 by hand during an examination, there is no discomfort due to the elasticity and low thermal conductivity of the housing 100.

By additionally coating the outer surface of the housing 100 of the present invention, it can be made resistant to scratches or scratches when a patient or medical staff holds the housing with their hands.

Therefore, the housing 100 of the present invention has the advantage of reducing manufacturing costs and being easily moved by using an inexpensive foamed styrene resin material, and has the advantage of being highly durable by preventing the propagation of bacteria or germs. However, the material of the housing 100 is according to one embodiment of the present invention, and can be sufficiently modified to use other materials as other embodiments of the present invention.

As shown in Figures 2 to 4, the housing 100 is composed of a front housing 110 and a rear housing 120. The front housing 110 is arranged to face the direction where the patient is located, and the rear housing 120 is arranged to face the direction where the medical staff is located.

The housing 100 is formed by combining the front housing 110 and the rear housing 120.

Although not shown, the front housing 110 and the rear housing 120 may be fastened to each other through a combination of screws and bolts, or may be fastened to each other by forming protrusions and grooves.

Alternatively, as shown in the drawing according to an embodiment of the present invention, the front housing 110 and the rear housing 120 can be coupled using a bonding film 200.

The bonding film 200 is attached along the outer surface of the edge of the housing 100 using an adhesive such as tape.

The bonding film 200 is formed to a certain width and is in close contact with the front housing 110 and the rear housing 120 at the same time, and the tensile stress of the bonding film 200 causes the front housing 110 and the rear housing ( 120) maintains the combined state.

In addition, in order to open the inside of the housing 100 for the purpose of servicing the filter unit 500, lower fan 600, and upper fan 700, which will be described later, arranged inside the housing 100, the coupling film 200 ), the inside can be easily opened by simply removing the.

In the present invention, the upper and lower parts of the housing 100 are referred to separately based on the open surface 130. Therefore, the upper part refers to the upper part of the upper edge of the open surface 130, and the lower part refers to the lower part of the lower edge of the open surface 130.

Referring to Figures 3 and 4, an intake port 180 through which air is sucked is formed in the lower part of the housing 100. The intake port 180 is an inlet that introduces air into the housing 100. The inflow of air through the intake port 180 is achieved by the intake pressure generated by the lower fan 600, which will be described later.

Referring to FIG. 2 , a perforated plate 400 in which a plurality of through holes 410 are formed is further provided above the intake port 180.

Since a flow of air is formed to flow into the interior of the housing 100 through the intake port 180, foreign substances such as dust or hair in the air can be filtered.

In addition, the intake port 180 is a part that receives air discharged from the descending outlet 170 by the air flow of the present invention, and is a part where droplets swept together and settled by the descending airflow collide, so these foreign substances and Droplets, etc. are collected in the perforated plate 400.

As shown in Figures 3 and 4, a filter receiving part 140, which is a groove in which the filter part 500 is accommodated, is formed at the lower part of the intake port 180. The air passing through the intake port 180 is purified by the filter unit 500 due to the intake pressure generated by the lower fan 600, which will be described later. Harmful ingredients such as viruses and bacteria contained in the droplets are collected in the filter unit 500. Accordingly, the purified air flows along the flow path 300 inside the housing 100.

As shown in FIG. 7, the air flowing through the intake port 180 and the filter receiving portion 140 flows in a vertical direction from the top to the bottom.

As shown in Figures 3 and 4, a lower hollow part 150 in which the lower fan 600 is disposed is formed horizontally at the lower part of the filter receiving part 140. The lower hollow portion 150 is a space where the flow direction of air changes.

The air flowing vertically through the intake port 180 and the filter receiving portion 140 is sucked into the lower fan 600 and then discharged horizontally.

The space of the lower hollow portion 150 can be formed in various ways depending on the number of lower fans 600 provided. Figure 5 shows the space of the lower hollow portion 150 according to the number of lower fans 600 provided.

Referring to FIG. 5(a), the lower fan 600 is provided as a single unit, and the space of the lower hollow portion 150 is communicated without being divided. Therefore, the lower fan 600 discharges air to the left and right, and the air moves in both directions.

Figure 5(b) shows a state in which a plurality of lower fans 600 are provided. The air passing through the filter receiving portion 140 is divided into the left and right lower hollow portions 150 and then introduced. The lower fan 600 located on the left discharges air in the left direction, and the lower fan 600 located on the right discharges air in the right direction. That is, the lower hollow portion 150 is formed by being divided into left and right sides.

The air passing through the lower hollow portion 150 flows upwards to the top of the housing 100 along the side flow path 330 formed as an empty space on both sides of the housing 100.

As shown in FIG. 6, an upper hollow portion 160 in which the upper fan 700 is accommodated is formed in the upper part of the housing 100. The upper hollow portion 160, like the lower hollow portion 150, is formed to have a length in the horizontal direction.

The upper hollow portion 160 receives air from the side flow path 330. In the side flow path 330, air flows vertically from the bottom to the top, and as it enters the upper hollow portion 160 from the top of the side flow path 330, the flow direction changes horizontally.

The air flowing in the horizontal direction in the upper hollow part 160 is discharged through the lowering outlet 170 under the blowing force of the upper fan 700. The air flowing horizontally in the upper hollow portion 160 is discharged through the lowering outlet 170 and changes its flow direction vertically downward.

The downward outlet 170 is a groove through which air is discharged from the inside of the housing 100 to the outside, and is directed toward the open surface 130. As the air is discharged through the lowering outlet 170, it sweeps down the open surface 130 and descends.

As shown in FIG. 8, the lowering outlet 170 is a space formed by the front housing 110 and the rear housing 120 being somewhat spaced apart. Air is discharged through the downward discharge port 170, which is a gap between the front housing 110 and the rear housing 120.

Lowering guide surfaces 171 are protruding on the front and rear sides of the lowering outlet 170. The descending guide surface 171 protrudes further downward in the vicinity of the upper hollow portion 160 and guides the air discharged through the descending outlet 170.

The air discharged through the descending outlet 170 tries to spread in the radial direction, but the descending guide surface 171 protrudes further downward, blocking some of the air flow directed radially rather than in a straight vertical direction. Allows air to flow only through.

Accordingly, the flow of air discharged through the descending outlet 170 is strengthened in straightness, and a descending airflow is formed that descends in the vertical direction parallel to the open surface 130.

The intake port 180, filter receiving portion 140, lower hollow portion 150, and upper hollow portion 160 described above are formed by combining the front housing 110 and the rear housing 120. An intake port 180, a filter receiving portion 140, a lower hollow portion 150, and an upper hollow portion 160 are formed in the front housing 110 and the rear housing 120, respectively, and the front housing 110 When the and rear housing 120 are combined, air can flow along the flow path 300 in the configuration listed above.

However, this is according to an embodiment of the present invention, and forming such a configuration in any one or more of the front housing 110 and the rear housing 120 is also included in the spirit of the present invention.

Hereinafter, the configuration provided and disposed in the housing 100 will be described with reference to FIG. 2.

A perforated plate 400 is disposed in the intake port 180. The perforated plate 400 is configured to meet first before air flows into the interior of the housing 100, and a plurality of through holes 410 are formed.

The width of the perforated plate 400 is formed to be larger than the width of the descending outlet 170, so that as the air discharged from the descending outlet 170 descends, the width gradually increases, but the through hole 410 of the perforated plate 400 ), and the air passing between the medical staff and the patient is also sucked in through the perforated plate 400.

The perforated plate 400 is in contact with air descending directly downward from the downward discharge port 170 and droplets coming from the front and rear sides of the housing 100. By allowing such droplets and air to flow only through the through hole 410 before flowing into the housing 100, the inflow of large foreign substances, etc. can be blocked.

Additionally, the perforated plate 400 can be easily separated from the intake port 180, allowing easy cleaning.

A sterilizing lamp 900 is disposed on the upper part of the front housing 110. The front housing 110 is disposed toward the patient (front) when the medical staff and the patient face each other, and the sterilizing lamp 900 provided in the front housing 110 is irradiated at an angle toward the patient.

Because medical staff deal with many patients, they must come into contact with many people suspected of being infected, and are therefore not safe from the risk of infectious diseases. If there is a face-to-face encounter with a person carrying an infectious disease, medical staff can also become infected, and the infectious disease can also be spread to many patients who come into contact with an infected medical staff member.

To prevent this risk, the sterilizing lamp 900 can sterilize the area around the patient, including the chair on which the patient sits, by emitting UV light toward the patient. If the sterilizing lamp 900 is activated after treatment for the patient is completed and before the next patient sits on the chair, the contaminated area around the patient can be purified, and the next patient can also receive treatment with peace of mind. Since the sterilizing lamp 900 irradiates diagonally toward the patient (front) rather than toward the medical staff (back), it can purify harmful components, including droplets, generated during the treatment process.

Therefore, even if medical staff encounters multiple patients, they can remove harmful ingredients contained in the droplets of possible carriers.

A filter part 500 accommodated in the filter receiving part 140 is disposed at the lower part of the perforated plate 400. The filter unit 500 may be provided as a single filter, but in one embodiment of the present invention, it is shown as being provided with two filters.

The filter unit 500 may be composed of a first filter 510 and a second filter 520. The first filter 510 may be formed as a pre-filter that filters foreign substances smaller than the through hole 410 that were not filtered out by the perforated plate 400.

The second filter 520 may be formed as a HEPA filter that filters and collects fine particles that the first filter 510 cannot filter. The first filter 510 is primarily filtered at the tip to improve the durability of the second filter 520, and the second filter 520 has an antibacterial effect against viruses and bacteria, thereby protecting the housing 100. Purifies the air flowing inside.

The lower fan 600 disposed in the lower hollow portion 150 is configured to generate suction force. The lower fans 600 are provided singly or in plural as shown in FIG. 5 .

As the lower fan 600 operates, intake pressure into the housing 100 is generated around the intake port 180. The air that flows into the lower hollow part 150 through the intake port 180 and the filter receiving part 140 according to the intake pressure is discharged from the discharge groove formed on the side of the lower fan 600.

Due to the intake pressure generated by the lower fan 600, air that descends in a descending airflow along the descending flow path 350 is sucked in from the descending discharge port 170, and also in the process of communication between the medical staff and the patient. The horizontal flow of air trying to penetrate the formed open surface 130 is also sucked in.

When passing through the intake port 180 and the filter receiving portion 140, the air flows vertically downward and then changes its flow direction to the horizontal direction as it is discharged from the lower fan 600.

Air flows from the lower hollow portion 150 to the upper hollow portion 160 through the side flow path 330 due to the discharge pressure of the lower fan 600.

The upper fan 700 disposed in the upper hollow portion 160 is formed in a horizontal direction corresponding to the longitudinal direction of the upper hollow portion 160.

While the lower fan 600 changes the vertical flow to the horizontal direction, the upper fan 700 changes the horizontal flow to the vertical direction.

The air discharge range by the upper fan 700 matches the length of the upper fan 700 or has only a slight difference. Therefore, since the discharge flow is formed in the longitudinal direction from the upper fan 700, it is uniformly distributed over the area of the open surface 130, and the air forming the descending airflow covers the entire area of the open surface 130. It flows downward in parallel.

In the present invention, the upper fan 700 is a fan that can be selectively used. The lower fan 600 can generate intake pressure and discharge pressure to circulate air along the flow path 300, but the lower fan 600 focuses on intake pressure and the upper fan 700 focuses on discharge pressure. By forming it, the flow of air can circulate more smoothly.

A transparent partition 800 may optionally be further provided at the rear of the open surface 130. Unlike sealing the open surface 130 to fluid flow, the transparent partition 800 is made of a solid structure and physically closes the open surface 130.

Two passage holes 810 are formed in the transparent partition wall 800. The passage hole 810 is a hole for passing through the open surface 130, and a medical staff member can put his hand through the passage hole 810 and contact the patient's body.

The transparent partition 800 is a configuration used to physically separate medical staff and patients when the risk of infection is very high. Gloves (not shown) are further provided in the passage port 810 to completely separate the medical staff from the patient, but allow the medical staff to contact the patient's body.

The transparent partition wall 800 is disposed in the partition receiving groove 121 formed in the rear housing 120. The partition receiving groove 121 is formed vertically in a direction parallel to the open surface 130. Accordingly, the transparent partition wall 800 disposed in the vertical partition receiving groove 121 is also arranged in the vertical direction.

The transparent partition 800 does not block the descending outlet 170, and can allow air discharged from the descending outlet 170 to descend from the front or rear side of the transparent partition 800.

The flow path 300 formed inside the housing 100 will be described with reference to FIG. 7 .

The flow path 300 is

A vertical filter flow path 310 flowing in from the intake port 180 and passing through the filter unit 500; a lower flow path 320 in which the flow direction is changed to the horizontal direction so that the air passing through the filter flow path 310 is directed to both sides of the housing 100 by the lower fan 600; A side flow path 330 that raises the air flowing in the lower flow path 320 to the upper hollow portion 160; A horizontal upper flow path 340 through which air at the top of the side flow path 330 moves toward the center of the upper hollow portion 160; and a descending flow passage 350 in which air flowing along the upper flow passage 340 is discharged through the descending outlet 170 and descends to close the open surface 130.

The filter flow path 310 is a flow path 300 in which air flowing from the outside to the inside of the housing 100 through the intake port 180 is purified as it passes through the filter unit 500. In the filter flow passage 310, air flows vertically downward.

The air sucked in from the intake port 180 includes air that forms a downward airflow through the downward discharge port 170, and droplets ejected toward each other while the medical staff and the patient communicate. The droplets are swept down by the descending airflow discharged from the descending outlet 170, pass through the perforated plate 400, and are collected in the filter unit 500. The air flowing along the above-mentioned descending flow path and the flow attempting to penetrate the open surface 130 in the horizontal direction flow in the open surface.

As the air passing through the filter flow path 310 enters the lower hollow portion 150, the flow direction is changed by the lower fan 600. The air changed from vertical to horizontal moves along the lower flow path 320 and moves to the edge of the housing 100.

At both ends of the lower flow path 320, air rises vertically upward from the side flow path 330. The side flow path 330 is formed on both sides of the housing 100.

Air flows along the side flow path 330 and enters the upper flow path 340 at the top. The flow that was moving in the vertical direction is bent as it enters the upper flow passage 340 and moves in the horizontal direction. The air flowing along the upper hollow portion 160 flows toward the center, some of which is discharged through the descending outlet 170 before reaching the center of the upper hollow portion 160, and some of which descends from the center. It is discharged through the outlet 170. The upper flow path 340 allows air to flow toward the center at both ends, and the upper fan 700 is formed in the longitudinal direction of the upper hollow portion 160, so that it matches the length of the upper hollow portion 160. Air is discharged uniformly from the descending outlet 170 formed so that the density of the air is constant. Therefore, the entire area of the open surface 130 can be covered with fluid flow.

The air discharged in a uniform distribution from the descending outlet 170 descends along the descending flow path 350 that closes the open surface 130 in a direction parallel to the open surface 130. The descending flow path 350 is formed to cover the entire area of the open surface 130.

In addition, the air discharged from the lowering outlet 170 is guided by the lowering guide surface 171 and flows directly downward rather than radially.

The air flowing along the descending flow path 350 is formed as a laminar flow. Accordingly, the open surface 130 is sealed and flows downward until it reaches the intake port 180.

Air flows along the flow path 300 and circulates inside and outside the housing 100. At this time, the air gains fluidity through the discharge pressure and intake pressure formed by the lower fan 600 and the upper fan 700.

Since the flow force is obtained from the upper fan 700, it flows along the descending flow path 350 and is sucked back into the intake port 180, the lower fan 600 is assisted by the strength of the intake pressure to intake air. The power required by the fan 600 is reduced.

The droplet blocking device according to one embodiment of the present invention is placed between the medical staff and the patient, and communication proceeds through the open surface 130, and the open surface 130 forms a descending airflow along the descending flow path 350. It is sealed by the flow of air, preventing droplets from being transmitted to each other.

Air flows into the housing 100 through the intake port 180 according to the intake pressure generated by the lower fan 600, is purified through the filter unit 500, and is discharged from the lower fan 600 into the lower flow path. It flows along (320) and the side flow path (330).

In the upper flow passage 340 connected to the upper end of the side flow passage 330, the air flows to the center of the upper hollow portion 160 and is discharged through the descending outlet 170, and is discharged by the descending guide surface 171. It does not radiate but flows directly downward, forming a laminar flow.

The air flows back into the intake port 180 from the bottom of the descending flow path 350 and circulates, thereby continuously closing the open surface 130.

As shown in FIG. 9(a), in the present invention, a stand 10 is provided at the lower part of the housing 100 and the open surface 130 is positioned at the eye level of the medical staff and the patient. The stand 10 is in contact with the ground through wheels at the bottom, so medical staff or patients can easily move it to an appropriate location.

Alternatively, in order to completely separate medical staff and patients and prevent the spread of infectious diseases, the housing 100 may be embedded in the wall 20 as shown in FIG. 9(b).

Therefore, the present invention not only prevents the spread of infectious diseases and protects both medical staff and patients, but also allows smooth communication through the open surface 130 to perfectly perform medical work.
