Description

  The present invention relates to a medical booth installed in a medical institution, a care welfare facility, a dental medical facility, etc. for the purpose of protecting a doctor from airborne bacteria and airborne viruses released from a patient with a patient's coughing and sneezing. .

  An air conditioning system for a hospital room that accommodates an infected or suspected patient has been proposed (see, for example, Patent Document 1). In addition, an air purification method and apparatus that captures and extinguishes influenza viruses and SARS viruses have been proposed (see, for example, Patent Document 2). Furthermore, a booth for diagnosis of chemical substance hypersensitivity has been proposed (see, for example, Patent Document 3).

  According to these, it is possible to prevent in-hospital contamination due to airborne bacteria and airborne viruses discharged with a patient's coughing and sneezing. However, it is not possible to protect doctors who are directly facing the patient for diagnosis and treatment from the patient's airborne bacteria and viruses.

  In addition, it has been proposed that a clean partition incorporating a HEPA filter is arranged behind a patient sitting directly opposite to a doctor sitting on a chair, and air is sucked from the back of the patient in a substantially horizontal direction ( For example, refer nonpatent literature 1). This air flow can prevent this cough from reaching the directly facing doctor's mouth unless the seated patient coughs toward the facing doctor's face.

  However, when a patient facing the doctor coughs toward the face of the doctor facing the doctor, the doctor cannot be reliably protected from airborne bacteria and viruses released from the patient.

“Reference Material on Severe Acute Respiratory Syndrome (SARS)”, page 2, b), [online] January 7, 2006, Japan Airtech Co., Ltd. [searched March 13, 2009], Internet <Http://www.airtech.co.jp/frame_products03.htm>

  Therefore, an object of the present invention is to provide a simple medical booth that can reliably protect a doctor from a patient who is infected or suspected of being infected.

  The medical booth according to the present invention has a ceiling part and a peripheral wall part, and is provided with an entrance / exit on the peripheral wall part, and a transparent or translucent film that closes the entrance / exit so as to be openable / closable is suspended from the ceiling part. An enclosure that divides a medical space in which a chair for a patient is placed into a room, and a fan device for holding the medical space at a negative pressure, and the membrane has a direction from the lower end to the ceiling portion. A mark is attached to a height position at least at a predetermined interval.

  In the medical booth according to the present invention, a patient enters the medical space partitioned by the enclosure so as to sit on a chair facing the membrane. A doctor separates the membrane from the outside of the medical treatment space, and gives medical care to the patient from below the lower end of the membrane. The height position of the mark attached to the membrane is compared with the height position of the patient's mouth, and the relative height positions of the two are set so that the latter is higher than the former. The height position of the patient's mouth differs depending on the patient's physique, and for the setting corresponding to this difference, for example, the height position of the seat surface of the chair of the patient is adjusted, or the height position of the lower end of the membrane Can be adjusted.

  By any adjustment, the membrane exists between a patient sitting in a medical treatment space where negative pressure acts and a doctor outside the medical treatment space who performs medical treatment on the patient, and the lower end of the membrane is It exists below the predetermined length from the height of the patient's mouth. Therefore, even if the patient coughs in a state of facing the doctor, the direct spray of the splash to the doctor is prevented by the film. Even if the patient coughs toward the lower end of the membrane, the negative pressure in the medical space causes cough splashes traveling toward the lower end to pass outside the medical space, i.e., from the doctor. It is prevented from reaching the mouth. Thus, a relatively simple configuration can reliably protect a physician from an infected or suspected infection patient.

  Most preferably, the predetermined interval is about 10 cm. That is, by placing the lower end of the membrane below 10 cm or more from the height of the patient's mouth, the doctor can be more easily protected from an infected or suspected infection patient.

  From this, the mark can be provided at a single height position of about 10 cm from the lower edge, which is the lower end of the film, and in this case, the height of the mark attached to the film and the mouth of the patient In comparison, the height position of the lower edge of the film can be adjusted by winding or lowering the film from its upper edge.

  In order to adjust the height position of the lower edge of the membrane, the membrane can be suspended via a winding device so as to be wound up and down. By operating this winding device, the mark can be adjusted so that it is located below the patient's mouth and the lower edge of the membrane is located at a height of about 10 cm from the height of the mouth. A sufficient gap for examination can be secured at the lower edge of the membrane and the doctor can be more reliably protected from infected or suspected infections.

  Alternatively, the mark may be applied to the film at at least two different height positions spaced from the lower edge of the film. In this case, the film is provided with means for maintaining a state of being wound up or down from its lower edge. In the example in which the holding means is provided, the film lower end is positioned at least 10 cm below the mark located below the height position of the patient's mouth and closest to the height position of the mouth. As such, the membrane is rolled up or down from its lower edge. Since the membrane is held by the holding means in this rolled-up or lowered state, the lower end of the winding or lowering that is the lower end of the membrane is lower than the height position of the patient's mouth at a predetermined interval. It is held so that it is located. Therefore, in this example as well, a sufficient gap for examination can be secured at the lower end of the membrane, and the doctor can be more reliably protected from infected or suspected infection.

  The holding means may employ a hook-and-loop fastener provided on the film. The hook-and-loop fastener is provided in a band shape on one side of the membrane from the lower edge of the membrane upward, and includes a first engagement surface provided with a hook portion and the first surface on the other side of the membrane. And a second engagement surface provided with a loop portion releasably engaged with the hook portion.

  Instead of the above-described example in which the lower end position of the membrane can be adjusted, the seat surface height of the patient's chair can be adjusted. In this case, the membrane is held in its free weight by its own weight. The membrane is marked at a single height with a predetermined distance from the lower edge of the membrane. The seating surface of the chair is adjusted in height so that the height position of the mouth of the patient sitting on the chair is located above the mark.

  The membrane is preferably composed of a transparent synthetic resin sheet having flexibility so as not to interfere with medical care.

  The mark is preferably a reference line extending along the width direction of the film for easy comparison with the height position of the patient's mouth position.

  It is desirable to set the horizontal velocity component orthogonal to the lower end to 30 cm / second or more for the air velocity toward the booth immediately below the lower end of the membrane. This is because the airflow velocity existing in a general hospital room is in the range of 0 cm / second to 20 cm / second, and the direction thereof is various. Under this environment, as will be described later, the blowing capacity of the fan device, or the blowing capacity and the medical treatment are set so that the horizontal velocity component of the airflow velocity toward the inside of the booth immediately below the lower end of the membrane is 30 cm / second or more. By setting the opening area of the entrance / exit of the booth, the patient is discharged from an infected or suspected infection regardless of the relationship between the direction of the wind in the medical booth and the direction of the environmental airflow by the operation of the fan device. It is because it can prevent more reliably that the microparticles | fine-particles containing an airborne microbe and airborne virus are accompanied by an air current from between the lower end of the said film | membrane and the said floor, and go to a doctor.

  Preferably, the fan device has a HEPA filter, and sucks air in the medical space through the HEPA filter so as to apply a negative pressure to the medical space.

  According to the present invention, a mark is attached to a membrane interposed between a patient sitting on a chair and a doctor, and by comparing the height position of the mark with the mouth of the seated patient, for example, the patient's cough The relative height position of the lower end of the membrane and the patient's mouth can be easily adjusted to a height position at which the droplets contained in can be prevented from going to the doctor. Thus, a relatively simple configuration can reliably protect a physician from an infected or suspected infection patient.

It is a perspective view schematically showing a medical treatment booth according to the present invention, It is the schematic which shows the usage example of the medical treatment booth shown in FIG. 1, and is explanatory drawing explaining the effect of a film | membrane, It is explanatory drawing explaining the effect of the film | membrane of the medical treatment booth which concerns on this invention, It is explanatory drawing explaining the setting method of the lower end of the film | membrane of the medical treatment booth which concerns on this invention, It is the schematic which shows the other example of the film | membrane shown in FIG. 1, (a) shows a front view, (b) shows a side view, It is a front view which shows the winding state of the film | membrane shown in FIG. It is drawing similar to FIG. 1 which shows the other example of the medical treatment booth which concerns on this invention.

  As shown in FIG. 1, a medical booth 10 according to the present invention covers a rectangular frame 12 having a depth (L), a width (W), and a height (H), and the rectangular frame 12. And an enclosure 14 made of a transparent resin film such as vinyl. The enclosure 14 is preferably subjected to an antistatic treatment. The enclosure 14 can be set to have a height dimension H of about 200 cm, a width dimension W of about 100 cm, and a depth dimension L of 120 cm, for example.

  As shown in FIG. 2, the medical booth 10 is installed on a floor 18 in a hospital room 16, for example. In the illustrated example, an air conditioner 20 is installed in the ceiling space 16a. The air conditioner 20 sucks room air through the suction port 16b on the room ceiling, purifies it, adjusts it to an appropriate temperature and humidity, and then supplies it into the room 16 through the air outlet 16c on the room ceiling. Due to this air circulation, the interior of the chamber 16 is maintained comfortably.

  Referring to FIG. 1 again, the envelope body 14 includes a rectangular ceiling portion 14a that covers the ceiling of the frame body constituted by the rectangular frame 12, and a pair of side walls formed along a pair of long sides of the ceiling portion. Portions 14b and 14b, and an end wall portion 14c formed along one short side of the ceiling portion 14a. The pair of side wall portions 14 b and 14 b and the end wall portion 14 c constitute at least a part of the peripheral wall of the enclosure 14.

  A portion (14d) facing the end wall portion 14c constituting one end of the medical booth 10 is open. Thereby, the other end of the vertically long medical treatment booth 10 is opened into the chamber 16 by the opening 14d for entering and exiting the patient 22 (see FIG. 2). Instead of this example, the opening (14d) of the medical booth can be formed along one of the long sides so that the medical booth 10 is horizontally long.

  A fan device 26 is installed on the end wall 14c of the medical booth 10 to suck the air in the booth 24 and maintain the inside of the booth at a negative pressure. The fan device 26 includes a suction port 26a that opens to a lower portion of the end wall portion 14c, and, for example, a HEPA filter 26b for purifying air sucked through the suction port, and the air purified through the HEPA filter is The air is discharged into the chamber 16 from the back surface of the fan device 26.

  In the example shown in FIG. 1, dust is accumulated in the booth 24, that is, in the floor corner in the enclosure 14, between the lower edges of the pair of side wall portions 14 b and 14 b and the end wall portion 14 c of the enclosure 14 and the floor 18. In order to eliminate this, a gap t of 10 cm or less (preferably about 5 cm) is set. This gap t can be made unnecessary.

  A flexible film 28 for opening and closing the opening is provided in the opening 14d of the enclosure 14. In the example shown in FIG. 1, the film 28 is held by a winding device 30 provided on the ceiling portion 14 a of the enclosure 14 so as to be wound. The membrane 28 can be made of transparent vinyl, which is the same material as the enclosure 14. The film 28 can be wound or pulled out by, for example, rotating the operating rod 30a of the winding device 30, and the lower edge 28a serving as the lower end of the membrane 28 can be moved up and down by operating the operating rod 30a. . Moreover, as the film | membrane 28, a thin film like a polyethylene film and a transparent or translucent flame-retardant sheet | seat are employable.

  In the illustrated example, the membrane 28 can be completely accommodated in the winding device 30 except for the lower edge 28a by the operation of the operation rod 30a. Accordingly, for example, when the patient 22 enters and exits the booth 24, which will be described later, the opening 14d can be fully opened. Further, the lower edge 28a of the membrane 28 is brought into contact with the floor 18 by the operation of the operation rod 30a, whereby the opening 14d can be fully closed.

  The film 28 is provided with a mark 32 for displaying a height position at a predetermined interval of, for example, 10 cm from the lower edge 28a. In the example shown in FIG. 1, the mark 32 is composed of a straight line made up of, for example, a black line that crosses the film 28 in the width direction. Instead of the straight line 32, a broken line can be used. Alternatively, for example, marks such as triangular marks may be arranged at equal intervals in the width direction of the film 28, or a pair of desired marks may be provided in the width direction of the film 28.

  The medical booth 10 according to the present invention is installed in a room 16 as shown in FIG. 2, for example. In general, until the patient 22 enters the medical booth 10, the doctor 36 stands by in a medical chart room (not shown) next to the medical booth, for example. After the patient 22 enters the clinic booth 10, the physician 36 sits in a chair 38 as described below and is positioned in front of the patient 22 separated by the membrane 28. Even if the patient 22 coughs or sneezes just before entering the medical booth 10, the direction of the air flow in the room is from the outside of the medical booth 10 toward the inside of the medical booth 24. Viruses contained in the sneeze do not scatter into the chamber 16.

  The medical booth 10 is accommodated in a booth 24 so that the patient 22 is seated on the chair 34 so as to face the membrane 28, and the doctor 36 is seated on the chair 38 so as to face the membrane 28 outside the medical booth 10. Used. At this time, the patient 22 sits on the chair 34 so as to place a distance of about 30 cm or less in a position close to the membrane 28, for example, the membrane 28 within a range where the feeling of pressure by the membrane 28 is not felt. As a result, the doctor 36 faces the patient 22 through the membrane 28 and performs a medical treatment such as a diagnosis or treatment by raising the lower edge 28a partially below the lower edge 28a of the membrane 28 or as shown in the figure. be able to. Therefore, the booth 24 is a medical space for the patient who accommodates the patient 22.

  Prior to the medical treatment, for example, the doctor 36 operates the operating rod 30a of the winding device 30 and the mark 32 (see FIG. 1) attached to the membrane 28 is the mouth 22a of the patient 22 seated on the chair 34 (see FIG. 3). The length from the winding device 30 to the lower edge 28a that is the lower end of the membrane 28 is adjusted so that the height position is lower than the height and does not interfere with medical care.

  By this adjustment, the doctor 36 can perform medical care in a state where the film 28 in which the lower edge 28a is located at least lower than 10 cm from the patient's mouth is interposed between the doctor and the patient 22. .

  Therefore, even if the patient 22 sitting on the chair 34 during this medical treatment coughs, for example, toward the face of the front doctor 36 with the face held substantially horizontal, as shown in FIG. Since the lower edge 28a of the membrane 28 is located below 10 cm above the height position of the mouth 22a of the patient 22, the droplet 40a is blocked by the membrane 28. As a result, the splash 40a is reliably prevented from going toward the mouth 36a of the doctor 36 by the film 28.

  Even if the patient 22 coughs with the face facing down toward the lower edge 28a of the membrane 28, the splash 40b reaching the vicinity of the lower edge 28a acts on the inside 24 of the booth by the operation of the fan device 26. Due to the negative pressure, the inside of the booth is pulled back toward the suction port 26a. As a result, it is possible to reliably protect the doctor 36 from airborne bacteria and airborne viruses released from the patient 22 with cough, for example.

  An example of the setting method of the lower end 28a of the film | membrane 28 is demonstrated along FIG. Assume that the patient 22 is sitting on a chair 34 such that the distance between the mouth 22a of the patient 22 and the vertical membrane 28 is 20 cm, for example. In this case, for example, the doctor 36 holds the lower edge 28a of the membrane 28 by hand, and the membrane 28 is inclined so that the lower edge 28a is close to the patient 22 as shown by the phantom line. The length of the membrane 28 is adjusted so that the mark 32 located 10 cm above the lower edge 28a is located at the height of the mouth 22a of the patient 22.

  At this time, for example, if the length to the lower edge 28a of the film 28 is 1 m, the angle between the inclined film 28 and the vertical line is 12.8 degrees. In this state, when the membrane 28 is returned to the vertical state as indicated by the solid line, the lower edge 28a is positioned at a height of the mouth 22a of the patient 22 about 12.2 cm below the position. Therefore, the lower edge 28a of the membrane 28 results in extending about 2.2 cm further to the safe side than the desired safe length (10 cm) from the height position of the mouth 22a of the patient 22. This slight extension does not interfere with medical practice.

  Regarding the negative pressure in the booth 24, the horizontal velocity component perpendicular to the drooping direction of the film 28 of the air flow 42 passing through the lower edge 28a of the film 28 can be ensured to be 30 cm / second or more in order to secure a desired negative pressure. desirable. That is, in a general hospital room, the speed of the airflow existing in the room 16 by the operation of the air conditioner 20 is 0 cm / second to 20 cm / second, and the direction is considered to be various. Therefore, regardless of the direction of the medical booth 10, that is, the direction of the wind 42, the splash 40 (40 a, 40 b) discharged from the patient 22 is prevented from spreading out of the booth and included in the spray 40. In order to surely capture the suspended fine particles of bacteria and viruses with the HEPA filter 26b of the fan device 26, the horizontal velocity component directed to the booth 24 perpendicular to the lower edge 28a has an air velocity immediately below the lower edge 28a of the membrane 28. It is desirable to set the value sufficiently exceeding 20 cm / second.

  Further, the gap between the lower edge 28a of the membrane 28 and the floor 18 of the chamber 16 varies depending on the physique or sitting height of the patient 22, but is considered to increase or decrease in the range of 60 cm from the average physique of the Japanese. Therefore, in consideration of the average sitting height and its deviation, the set height position of the lower edge 28a of the membrane 28 at the time of medical treatment is ± 1 m from the floor 18 of the chamber 16 as a reference, assuming that 1 m is the average height of the sitting position. Increase or decrease in the maximum range of 30 cm.

  Under these circumstances, with the lower edge 28a of the membrane 28 held at 1 m which is the reference value from the floor 18, the fan device 26 operates to make the air velocity directly below the lower edge 28a orthogonal to the lower edge 28a. Then, if the air blowing capability that can secure the horizontal velocity component toward the booth 24 at 30 cm / second or more can be exhibited, even if the lower edge 28a of the membrane 28 increases or decreases within the maximum range of ± 30 cm, the negative pressure in the booth 24 is increased. Can be substantially retained. Therefore, as described above, the lower edge 28a of the membrane 28 is disposed at a distance of 1 m from the floor 18, and the air velocity immediately below the lower edge 28a is a horizontal velocity component that is orthogonal to the lower edge 28a and travels toward the booth 24. By using the fan device 26 that can hold the pressure at 30 cm / second or more, an appropriate negative pressure can be reliably held in the booth 24 regardless of the height adjustment of the lower edge 28a of the membrane 28 described above.

  Of course, the amount of air blown by the fan device 26 can be made variable according to the height position of the lower edge 28a of the membrane 28. The design capability of the fan device 26 may be selected based on the booth opening area when the lower edge 28a of the membrane 28 is 1.3 m above the floor. Alternatively, although not shown, an auxiliary air blower such as a fan that generates an air flow toward the booth 24 can be arranged in the booth 24 or under the doctor 36 outside the booth. . That is, for the fan device 26, when the design capability is set based on the height of 1 m above the floor as the position of the lower edge 28a, and the lower edge 28a of the membrane 28 is positioned above that, the auxiliary air conditioner ( (Not shown) can be activated.

  The patient 22 can also sit at an angle so that its upper body is at a slight angle from the direction across the air flow to reduce resistance to the flow of air 42.

  In the above description, an example in which the winding device 30 for the membrane 28 is provided has been described. However, without providing the winding device 30, the membrane 28 is directed from the ceiling portion 14a of the enclosure 14 to the floor 18 in a free state. Can be hung down. In this case, the lower edge 28a of the membrane 28 is preferably at a height of 70 cm from the floor 18. Further, as shown in FIGS. 5A and 5B, the film 28 is provided with three lines 32a to 32c as a plurality of marks 32 at a predetermined interval (for example, 10 cm) from the lower edge 28a. Has been.

  Furthermore, first and second engaging surfaces 44a and 44b of the surface fastener 44 are formed in a band shape on both the front and back surfaces 28b and 28c (see FIG. 5B) of the film 28. As shown in FIG. 5A, a pair of strip-shaped first engaging surfaces 44a and 44a are formed on one surface 28b from the upper edge to the lower edge 28a of the film 28 along both side edges. Has been. A pair of band-like second engagement surfaces 44b, 44b are formed on the other surface 28c of the film 28 in correspondence with the pair of band-shaped first engagement surfaces 44a, 44a.

  As is well known in the art, for example, one of a hook portion and a loop portion is formed densely on the first engagement surface 44a, and the hook portion and the loop portion are formed on the second engagement surface 44b. The other side of the loop portion is formed densely. As is well known, the hook portion has a bowl shape or a mushroom shape, and is releasably engaged with the loop portion.

  According to the film 28 provided with the hook-and-loop fastener 44, as shown in FIG. 6, the film 28 is sequentially wound up manually from its lower edge 28a. At the time of winding up, the membrane 28 is folded or rolled, and either the front surface or the back surface of the membrane is pressed against the other, and the first engagement surface 44a provided on the front and back of the membrane 28 and the engagement surface By winding up the second engaging surfaces 44b corresponding to the above while pressing each other, the rolled-up state can be maintained. The same applies to the case where the film is rolled down to adjust the lower edge 28a of the film 28.

  In the film 28 shown in FIG. 6, for example, it is assumed that the mouth of the patient 22 is located near the line 32 c located at the top in FIG. 5 and above the line. In this case, as shown in FIG. 6, the film 28 is wound up from the lower edge 28a so that the line 32b located immediately below the line 32c is located at the lower end of the film 28, and the surface fastener 44 serving as the holding means The winding state is maintained. Thereby, the winding lower end (32b) serving as the lower end of the membrane 28 is held so as to be positioned below the height position of the mouth 22a of the patient 22 at a predetermined interval. Therefore, as in the example shown in FIGS. 1 to 4, the doctor 36 can be reliably protected from the infected patient (22) in the booth 24 or suspected of being infected. Further, when the patient 22 whose height is lower than the above-mentioned patient sits on the chair 22 and the height position of the mouth 22a is, for example, immediately above the line 32b, the film 28 is positioned so that the line 32a is at the lower end of the film 28. Rolled up. As described above, the plurality of lines 32 (32 a to 32 c) are selectively used according to the height of the patient 22.

  The surface fastener 44 can be formed only in a region necessary for winding up the lower edge 28a. However, if the hook-and-loop fastener 44 is formed in the height region of the membrane 28, the opening 14d can be held almost fully open, so that the patient 22 enters and leaves the enclosure 14 and the booth 24 is cleaned. This is advantageous.

  In the examples described above, the example in which the length of the film 28 interposed between the patient 22 and the doctor 36 is adjusted toward the floor 18 has been described. Instead of adjusting the length of the membrane 28, the mouth 22 a of the patient 22 seated on the chair 34 is positioned above the reference mark 32 attached to the membrane 28 at a predetermined interval from the lower edge 28 a. In addition, when the seat surface 34a (see FIG. 2) of the chair 34 for the patient 22 can be adjusted in height, the seat surface 34a can be adjusted.

  Further, in the above description, the example in which the suction port 26a of the fan device 26 is provided in the end wall portion 14c of the enclosure 14 has been described. However, as shown in FIG. 26b and a suction port (26a) that performs the same function as described above can be provided. In this case, the air 42 drawn in the horizontal direction into the booth 24 from the lower edge 28a serving as the lower end of the membrane 28 rises toward the suction port of the ceiling portion 14a within the booth 24. Changing the airflow at 24 does not substantially affect the negative pressure retention within the booth 24.

  The present invention is not limited to the above embodiments, and various modifications can be made without departing from the spirit of the present invention. For example, the ceiling part, the side wall part, and the end wall part excluding the envelope film can be made of a plate material such as a synthetic resin board. In addition, as the predetermined interval between the lower edge of the film and the mark or the interval between the plurality of marks, an example of about 10 cm is shown in paragraph 0042, but the predetermined interval can be set to 5 cm, for example. In this case, in the example in which the winding device as shown in FIG. 1 is provided, two marks (5 cm × 2) are positioned on the lower edge of the membrane below the height position of the patient's mouth. The length is adjusted.

  A position lower than the patient's mouth can be selected as the reference position of the mark to be compared with the height of the patient's mouth, and a position recognized by the doctor as the patient's mouth position can be used as the reference position. In addition, a mark can be projected on the film by installing a laser pointer at the patient's mouth and irradiating the film with laser light from the laser pointer.

  The medical treatment booth according to the present invention can be installed for medical treatment in various medical institutions, nursing care welfare facilities, etc. in addition to dental medical treatment.
