Description

Infectious disease isolation-patient tailored negative pressure chamber {Patient tailored-installable negative pressure isolator}

The present invention relates to an infectious disease isolation-patient-customized negative pressure chamber that can be used to prevent the spread of pathogens (viruses, etc.) through droplets or aerosols. It relates to a negative pressure chamber customized for the isolation of infectious diseases that can provide an independent isolation space for each patient and can be used in various ways with a structure that can be flexibly modified according to the situation.

Problems arise due to the unexpected outbreak of infectious diseases in the medical process related to the acceptance and treatment of patients. From SARS in 2002, H1N1 influenza A in 2009, Middle East Respiratory Syndrome (MERS) in 2015, and Corona 19 (COVID19) in 2019, a variety of new infectious diseases have occurred and spread rapidly. As the number of infected people increases explosively, problems such as a shortage of ward are appearing. In particular, the isolation problem of the infected, which appears as a characteristic of an infectious disease, is a problem that must be solved in order to prevent the spread of the infectious disease and to prevent the loss of medical resources that may occur in the course of treatment.

For example, in the case of Corona 19 (COVID19), which is prevalent worldwide as of 2020, an indirect transmission route through a surface contaminated with droplets is also effective as a respiratory infectious disease having an airborne transmission route through droplets, etc. It is known to have a high infectivity that cannot be excluded from the possibility of transmission. In order to effectively isolate patients infected with these infectious diseases, a negative pressure room with a lower internal pressure than the outside is required. Negative pressure wards usually exist as separate wards because they require facilities for pressure control, etc., and there may not be sufficient numbers in the hospital. For this reason, in the prior art, in case of an emergency, a technique of temporarily configuring the entire negative pressure ward to the outside has been used (eg, Korean Patent Registration No. 10-1646524, etc.).

However, even in the ward, the medical staff is still exposed to the source of infection, so there are still difficulties in the overall medical procedure performed in each hospital bed due to various protective equipment. In addition, there is a limit to temporarily installing the entire negative pressure room, so there is a problem that there is still a shortage of negative pressure isolation beds. In addition, a negative pressure cart with a closed structure is used to transport an infected person. In such a case, the problem of spreading infection remains because the sealed structure must be released to access the patient. In addition, even when an infected person or a patient suspected of being infected receives various treatments or procedures for various conditions, it is difficult for medical staff to respond more effectively because they are not in appropriate isolation conditions. These problems cannot be solved by the current technology, so an appropriate solution is needed.

Republic of Korea Patent Publication No. 10-1646524, (2016. 08. 08)

Advantages and features of the present invention and methods for achieving them will become apparent with reference to the embodiments described below in detail in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but can be implemented in various different forms, and only these embodiments allow the disclosure of the present invention to be complete and common knowledge in the art to which the present invention pertains. It is provided to fully inform the possessor of the scope of the invention, and the present invention is only defined by the claims. Like reference numerals refer to like elements throughout.

Hereinafter, with reference to FIGS. 1 to 11 , an infectious disease isolation-patient-customized negative pressure chamber according to the present invention will be described in detail. First, an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 7, and other embodiments will be described in detail with reference to FIGS. 8 to 11 based on this.

1 is a perspective view of an infectious disease isolation-patient-customized negative pressure chamber according to an embodiment of the present invention, FIG. 2 is a perspective view of the infectious disease isolation-patient-customized negative pressure chamber of FIG. 1 viewed in a different direction, and FIG. 3 is FIG. It is a perspective view showing the expanded state of the variable cover of the patient-customized negative pressure chamber for isolating infectious diseases.

1 to 3 , the negative pressure chamber 1 customized for infectious disease isolation according to the present invention includes a fixed cover 100 that covers the patient's face in the form of a case, and is connected to the fixed cover 100 and is deformed. It includes a variable cover (300). The fixed cover 100 and the variable cover 300 have internal spaces connected to each other so that when air is sucked through the intake pipe 170 connected to one side, the pressure of the entire connected internal space is lower than that of the outside. Therefore, the negative pressure-isolation space isolated from the outside can be formed inside the negative pressure chamber 1 customized for the infectious disease isolation-patient.

In particular, the fixed cover 100 is adapted to accommodate the patient's head side in a fixed form, and the variable cover 300 is formed to change and accommodate the lower part of the patient's torso. That is, the variable cover 300 is deformed as illustrated in FIGS. 1 and 3 and can be stretched and contracted along the body of the patient, thereby forming a negative pressure-isolation space of an appropriate size to fit the body of the patient. By adjusting the variable cover 300 as necessary, the negative pressure-isolation space can be expanded or reduced, and through this, the body of a patient requiring a separate treatment or procedure can be exposed to the outside of the negative pressure-isolation space. Therefore, it is possible to smoothly perform a more suitable treatment or procedure while significantly lowering the risk of infection for medical staff.

The negative pressure chamber 1 customized for the infectious disease isolation of the present invention is specifically configured as follows. For infectious disease isolation - patient-customized negative pressure chamber (1), the support plate 200 disposed on the back of the patient lying down, connected to the support plate 200 to cover the patient's face, and an intake pipe for sucking internal air on one side ( 170) is connected, the inside is maintained at negative pressure, and is connected to the fixed cover 100 having an opening (refer to 101 in FIGS. 4 and 5) formed in the direction of the patient's body, and the opening 101 of the fixed cover 100, , it expands and contracts along the body of the patient and covers the patient, and includes a variable cover 300 in which the internal negative pressure space communicating with the fixed cover is variable. At this time, the internal negative pressure space may mean a space inside the variable cover 300 among the negative pressure-isolation spaces in the aforementioned chamber.

According to an embodiment of the present invention, in the infectious disease isolation-patient-customized negative pressure chamber (1), the support plate 200 may be formed detachably from the fixed cover 100, and the support plate 200 is at different points of the larynx. It may consist of a plurality of dividers (including a first divider plate (see 200a in FIG. 5) and a second divider plate (see 200b in FIG. 5)) that are disposed on and are separated and coupled to each other. Accordingly, the fixed cover 100 may be coupled to the support plate 200 in a sliding manner from one end of the support plate 200 after supporting the patient's head on the support plate 200 (see FIG. 6 ). Hereinafter, the configuration, operation and effect of the negative pressure chamber 1 customized for infectious disease isolation-patient based on an embodiment of the present invention will be described in more detail. Hereinafter, various other features of the present invention that are not already mentioned through the description may be more clearly understood.

The patient-specific negative pressure chamber 1 for infectious disease isolation of the present invention may be largely composed of three parts. The support plate 200 and the fixed cover 100 are connected to each other to surround the patient's head, and the variable cover 300 is extended from the fixed cover 100 to cover the lower part of the patient's torso. The support plate 200 is disposed on the occipital side of the lying patient and serves to support the patient's head. The support plate 200 may be formed integrally with the fixed cover 100 , but may be formed to be detachably coupled to the fixed cover 100 as in this embodiment. Since the support plate 200 of this embodiment is detachable from the fixed cover 100, it can be more conveniently inserted into the back of the head of a patient lying in a separated state, and is fixed in a state in which the support plate 200 is disposed as such. The cover 100 and the variable cover 300 can also be installed more smoothly. A specific installation process will be described later in more detail.

The support plate 200 may have an appropriate area enough to accommodate the patient's head and may be formed in a rectangular panel shape as a whole. The support plate 200 may include a buffer pad 210 disposed on a surface in contact with the patient's head to protect the patient's head from impact. As will be described later, the support plate 200 is composed of a plurality of split plates (see 200a and 200b in FIG. 5) that are arranged at different points of the occipital region and can be separated and coupled to each other, so it is easy to install even for severe patients, etc. can be applied Through this, the negative pressure-isolation space can be formed more conveniently. When the support plate 200 is dividedly formed as in the present embodiment, the buffer pad 210 may also be divided correspondingly. The support plate 200 is disposed on the occipital side of the patient and can be deformed in various forms within the limit that can support the head, so there is no need to understand it limitedly as in this embodiment.

The fixed cover 100 is connected to the support plate 200 and is formed to cover the patient's face. That is, the support plate 200 extends to the back of the patient's back and the fixed cover 100 extends to the opposite side to surround the patient's face, so that the patient's head is inside the space surrounded by the fixed cover 100 and the support plate 200 . can be placed on 1 to 3, the fixed cover 100 is connected to the support plate 200 to shield the internal space from the outside, and through the opening (refer to 101 in FIGS. 4 and 5) opened in the direction of the patient's body. It is connected to the variable cover (300). As described above, the fixed cover 100 may be formed in a three-dimensional housing shape such as a hard case, and an intake pipe 170 for sucking internal air may be connected to one side thereof. Accordingly, the inside of the fixed cover 100 may be maintained at negative pressure. The intake pipe 170 may form a through hole on one side of the fixed cover 100 to combine one end with the fixed cover 100 as shown. A pressure control facility including an intake pump (not shown) may be connected to the other end of the intake pipe 170 (not shown).

The fixed cover 100 is formed so that at least a part of the door is made of a light-transmitting material so that the inside can be visually recognized. The medical staff can check the condition of the patient through the transparent fixing cover 100 and provide necessary treatment. The fixed cover 100 may be formed of, for example, a light-transmitting plastic having high hardness, and if necessary, the light-transmitting material may be applied to some or all of the fixed cover 100 . In addition, the fixed cover 100 includes at least one treatment instrument on one side of which at least one of the body of the medical staff and the medical instrument can enter and exit. For example, the treatment instrument may include a plurality of treatment instruments such as first treatment instruments 110a and 110b and second treatment instruments 110c arranged in different positions as shown in FIGS. 1 to 3 . . Among them, the first treatment tool (110a, 110b) can be used more conveniently for medical staff to access the patient in the negative pressure-isolation space by putting both arms, and the second treatment tool (110c) is for various treatments such as airway intubation. It can be conveniently used to enter and exit medical equipment. That is, a pair of treatment tools are arranged side by side on the opposite side of the opening 101 of the fixed cover 100, like the first treatment tools 110a and 110b, so that both arms of the medical staff can be inserted from the patient's parietal side. . However, the treatment tool does not need to be limited in this way, and the location can be appropriately increased or decreased as needed. In addition, since each treatment tool does not need to be limited to its purpose, it does not depart from the technical spirit of the present invention even if it is used for purposes other than the examples.

As shown in FIG. 2 , on one surface of the fixed cover 100 adjacent to the treatment instrument, a light-transmitting surface 130 made of an inclined surface facing the gaze direction of the medical staff may be formed. The light transmitting surface 130 may be entirely made of the above-described light transmitting material, and may be formed as a smooth curved surface or a flat inclined surface that is not excessively refracted so as not to distort an internal image. Disposed to face the line of sight of the medical staff means, for example, that when the medical staff looks into the fixed cover 100 , the line of sight is disposed to pass perpendicularly to the tangent of the light transmitting surface 130 or the light transmitting surface 130 . can mean That is, as described above, when the medical staff inserts both arms into the first treatment tools 110a and 110b and inserts them from the patient's parietal side, the gaze forming a downward slope at a certain angle in the direction from the medical staff's head located higher than that is formed. If possible (refer to (b) of FIG. 7), it is possible to provide a clearer and wider field of view by using the light-transmitting surface 130 that is appropriately inclined in the direction of receiving the gaze. As a result, the medical treatment can be performed more accurately and smoothly. In addition, since the inclined surface is formed on the outer surface of the fixed cover 100 as described above, the medical staff can approach the patient on the inside of the fixed cover 100 more closely. That is, the medical staff can approach the patient more closely while checking the patient through the light-transmitting surface 130 formed as an inclined surface to perform an accurate treatment or treatment.

The fixed cover 100 may include various structures having various functions within the limit of covering the patient's face as described above. Accordingly, the fixed cover 100 may form an atypical three-dimensional shape as shown in FIG. 2 . The above-described first treatment tools (110a, 110b) may be located under the light transmitting surface 130, and may protrude in part. A handle 140 may be formed on the upper end of the fixed cover 100 to facilitate handling, and a removable filter 120 may be coupled to one side of the fixed cover 100 . A removable coupling part 150 for removably connecting the variable cover 300 and the fixed cover 100 is formed between the variable cover 300 and the fixed cover 100 to be described later, so that the separation and coupling between them are easily formed. can be Hereinafter, the structural features of the present invention will be described in more detail with reference to FIGS. 4 and 5 along with FIGS. 1 to 3 .

4 is a longitudinal cross-sectional view of the patient-customized negative pressure chamber for isolation of infectious diseases of FIG. 3 , and FIG. 5 is an exploded perspective view of the negative pressure chamber customized for isolation of infectious diseases of FIG. 1 .

The variable cover 300 is connected to the opening 101 of the fixed cover 100 and covers the patient as it expands and contracts along the body of the patient. Accordingly, as shown in FIG. 4 , the internal negative pressure space communicating with the fixed cover 100 may also be varied. That is, the fixed cover 100 and the variable cover 300 are connected to each other to form a sound pressure-isolated space blocked from the outside, and the sound pressure-isolated space can be varied according to the expansion and contraction of the variable cover 300 . have. Variability is mainly shown by deforming the sound pressure space inside the variable cover 300 according to the expansion and contraction of the variable cover 300 . The variable cover 300 is made of a flexible material and is fixed in close contact with the patient's body while being stretched or folded along the patient's body. The variable cover 300 may be formed of, for example, a flexible plastic material, and may be formed of a material having light transmittance. For example, the variable cover 300 may be formed of a material such as vinyl. If necessary, a skeleton structure, etc. may be formed on one side of the variable cover 300 with a plastic material or another material having high hardness, and the variable cover 300 may be appropriately molded to be folded or unfolded in a predetermined shape. The variable cover 300 may be easily folded and unfolded in a shape such as a bellows, for example. At the distal end of the variable cover 300, a contact portion 310 that is in close contact with the patient's body may be formed, and the contact portion 310 has elasticity and is in close contact with the patient's body or is plastically deformed to maintain the curvature of the body. can be formed in this way. However, since this is an example, it is not necessary to be limited in this way, and the adhesion part 310 may be formed of various materials or structures that can be in close contact with the patient's body.

The above-described removable coupling part 150 is formed between the variable cover 300 and the fixed cover 100 so that both can be easily combined and separated. The removable coupling unit 150 may have a structure including, for example, a zipper, but may also include various other detachable structures. The detachable coupling part 150 may be closely coupled to form a sealing structure, and the coupling structure may be the same as or different from each other, or a combination of two or more coupling methods. The variable cover 300 and the fixed cover 100 can be easily detached and the removable coupling part 150 can be formed in various ways that can effectively form a shielding structure. The removable coupling part 150 may be formed symmetrically with each other at the ends of the opening 101 of the fixed cover 100 and the variable cover 300 in contact therewith.

The variable cover 300 is connected to the fixed cover 100 , but is also connected to the support plate 200 side to enhance structural stability. For example, as shown in FIG. 5 , the extension part 220 protrudes from the support plate 200 and expands and contracts along the body from both sides of the patient, and one side of the extension part 220 and the variable cover 300 is They may be formed to be removably coupled to each other. For example, as shown on one side of the extension part 220 and the variable cover 300 in contact with it, the fixing part 230 may be formed symmetrically to each other. The fixing part 230 may be formed using, for example, Velcro coupled to each other by magnetic force or detachable from each other. That is, the variable cover 300 may be fixed to the extension part 220 by a magnetic fixing method or a Velcro fixing method. That is, it can be formed to easily finish the sealing structure by connecting the variable cover 300 to the support plate 200 side using a relatively easily detachable structure. The extension 220 may be formed in a shape as slidably coupled to the support plate 200 as shown, and may be formed in a structure that is folded in multiple stages if necessary. When the extension part 220 is combined with the variable cover 300 , it expands and contracts together with the expansion and contraction of the variable cover 300 , and can support the variable cover 300 . The extension part 220 extends outside each partition plate when the support plate 200 is formed of the first partition plate 200a and the second partition plate 200b as in this embodiment and may be arranged in pairs. .

As described above, the support plate 200 may be formed of a plurality of partition plates disposed at different points of the occipital region and capable of separation and coupling. For example, as in this embodiment, the support plate 200 may include a first partition plate 200a and a second partition plate 200b that are respectively inserted into and coupled to the left and right sides of the occipital part around the patient's neck. . As shown in FIG. 5 , the first dividing plate 200a and the second dividing plate 200b may be formed to be symmetrical to each other, and a buffer pad 210 may be divided and disposed in each. When the first dividing plate 200a and the second dividing plate 200b are coupled to each other, the buffer pad 210 may be in close contact with each other to support the back of the head like a single pad. The first dividing plate 200a and the second dividing plate 200b may also be detachably coupled and, for example, may be coupled using a coupling structure such as the ring portion 201 and the engaging portion 202 . The locking portion 202 may have a structure such as a protrusion or a bar, and the ring portion 201 may have a structure that swings elastically and is caught on the locking portion 202 . Such a structure may be symmetrically disposed at one or more portions facing each other of the first dividing plate 200a and the second dividing plate 200b to be easily attached and detached from each other. However, since this is an example, it is not necessary to be limited thereto, and it is possible to form detachably in other ways by using various other coupling structures.

The fixed cover 100 and the support plate 200 may be formed to be slidably coupled to each other. That is, after supporting the patient's head on the detachable support plate 200 as described above, the fixed cover 100 can be coupled from one end of the support plate 200 in a sliding manner. For example, a rail groove 160 is formed in one of the fixed cover 100 and the support plate 200 , and a protrusion 240 slidably coupled to the rail groove 160 is formed in the other, so that a slidable coupling structure is formed. can achieve As shown in FIG. 5 , rail grooves 160 parallel to each other may be formed on both sides of the opening 101 at the lower end of the fixed cover 100 , and the rail grooves 160 and parallel to the rail grooves 160 may be formed at corresponding positions of the support plate 200 . The shape of the protrusion 240 may be formed. The protrusion 240 may be inserted into the rail groove 160 and slid or discharged and separated. With this structure, a very effective sliding coupling structure can be implemented. The positions of the protrusion 240 and the rail groove 160 may be interchanged, and the number of the protrusion 240 and the rail groove 160 may be increased for stability. By appropriately disposing the protrusion 240 and the rail groove 160, a slidable coupling structure can be formed.

On the other hand, each treatment tool of the fixed cover 100 may be formed with a multi-sealable structure. As shown in FIGS. 4 and 5 , the treatment instrument can be protected by overlapping the outermost valve body 111 , the blocking film 112 at the midpoint, and the inner shielding plate 113 . The valve body 111 may be opened and closed in a manner such as an iris, for example, and may be formed in the same structure as a conventional iris valve. The valve body 111 may be opened and closed by operating the lever 111a on one side. The blocking film 112 may be formed of a flexible film with a hole in the center, and as shown in FIG. 4 , the thickness is decreased toward the distal end, so that when a medical staff's arm is inserted, it is closely attached to the periphery to form a shielding structure. The shielding plate 113 may be formed by forming a flexible plate in a circular shape to correspond to the shape of the treatment instrument and cutting it in a rotationally symmetrical form. Accordingly, when the medical staff's arm is inserted, it spreads outward from the center to open the treatment tool. Such a structure can be effectively shielded by overlapping the perimeter of a body or medical device inserted into the fixed cover 100 from the outside by overlapping multiple. The valve body 111 need not be limited to a structure such as an iris valve, and if there is another effective opening/closing structure, such a structure may be used. The shielding film 112 and the shielding plate 113 are made of, for example, elastic material, and when the deforming factor is removed, the shielding film 112 and the shielding plate 113 are restored to their original shape and can immediately shield the treatment device. In this way, by forming multiple sealable structures in each treatment unit (including the first treatment unit 110a, 110b and the second treatment unit 110c), it is possible to effectively prevent the spread of the infectious agent.

If necessary, the sanitary gloves 180 may be disposed inside the treatment instrument of the fixed cover 100 and used. For example, as shown in FIG. 5 , the sanitary gloves 180 connected to the inside of the first treatment tools 110a and 110b into which both arms of the medical staff can be inserted may be formed. The sanitary gloves 180 may be detachably disposed using various detachable structures, and may be used in combination as shown in FIG. 5 as needed. Through this, it is possible to increase the shielding effect while reducing the protective equipment for the medical staff and reducing the burden. However, if necessary, the sanitary gloves 180 can be removed at any time and switched to the state shown in FIGS. Even in such a case, since the above-described shielding structure of the valve body 111 , the blocking film 112 , and the shielding plate 113 is still operated, the spread of the infectious agent can be effectively prevented. The sanitary glove 180 may be formed of, for example, a rubber material that can be stretched and contracted.

Such an infectious disease isolation-patient-customized negative pressure chamber 1 of the present invention can be installed and used very conveniently on a hospital bed, etc. as follows. Referring to FIG. 6, the patient (A) may already be lying on the bed, but as shown in FIGS. 6 (a) and (b), the first partition plate 200a and the second partition plate on both sides of the 200b) can be inserted to support the patient's (A) head. That is, as described above, the first dividing plate 200a and the second dividing plate 200b are divided and inserted into the left and right sides of the occipital region with the neck of the patient A as the center, and they are laid down in a way that combines them in the middle. The support plate 200 can also be conveniently and effectively disposed on the back of the patient (A). Thereafter, by using the above-described sliding structure, the fixed cover 100 can be coupled while maintaining the patient A in a stable lying state as shown in FIG. 6(c). That is, the fixed cover 100 and the support plate 200 can be combined very conveniently while sliding the fixed cover 100 in a direction parallel to the protrusion 240 of the support plate 200 described above. In this case, the variable cover 300 may be previously coupled to the fixed cover 100 , or may be coupled after coupling the fixed cover 100 with the support plate 200 . In this way, the support plate 200, the fixed cover 100, and the variable cover 300 are interconnected according to the patient A, and an independent negative pressure chamber can be installed for each bed by adjusting the variable cover 300. . The variable cover 300 may complete fixing by matching the extension part 220 and the fixing part 230 to each other. If you want to dismantle it, you can disassemble it very conveniently in the same way by proceeding in the reverse order.

The patient-customized negative pressure chamber 1 for infectious disease isolation may be utilized in various ways as shown in FIG. 7 . After connecting the support plate 200, the fixed cover 100, and the variable cover 300 to suit the patient A through the above-described process, the variable cover 300 is adjusted to fit the patient's body in close contact with the intake pipe ( 170) and inhaling air, a negative pressure-isolation space tailored to the patient (A) is formed. The negative pressure-isolation space is formed on the outside of the body of the patient A as an area surrounded by the fixed cover 100 and the variable cover 300, and does not necessarily surround the entire body of the patient A. That is, when the variable cover 300 is fixed in a contracted state as shown in (a) of FIG. 7 , the negative pressure formed inside the fixed cover 100 and the variable cover 300 - the isolation space can be reduced to a minimum state. Instead, more of the rest of the body, such as the patient's (A) abdomen, can be exposed outside the isolation space. Therefore, the medical staff can safely provide the necessary treatment to the patient (A) outside the negative pressure-isolation space inside the negative pressure chamber. The variable cover 300 can be completely in close contact with the body of the patient A by adjusting the close contact portion 310 of the distal end as described above, and the support plate 200 side through the fixed portion 230 in addition to the fixed cover 100 . It can be structurally stable by being over-connected. In addition, the medical staff can expand the variable cover 300 as shown in (b) of FIG. 7 to widen the negative pressure-isolation space and provide necessary treatment. In such a case, structural stability can also be maintained by extending the extension 220 according to the variable cover 300 as described above. In addition, if necessary, a tighter isolation space may be formed by arranging the adhesion band 320 on the body of the patient A and combining the ends of the adhesion band 320 and the variable cover 300 . The adhesion band 320 may be formed of, for example, a band having elasticity formed with Velcro on the outside, etc., and may be in close contact with each other by forming a Velcro or the like coupled thereto to the adhesion part 310 of the end of the variable cover 300, etc. have. In addition, although not specifically shown, at least a portion of the variable cover 300 may be formed in a double or multiple structure to strengthen the negative pressure-isolation space, for example, the close contact portion 310 that is in close contact with the body of the patient A, etc. It is possible to effectively seal the negative pressure-isolation space by forming an additional extended structure that covers the close contact area on the outside of the . This additional extension structure can also serve as a kind of front room by creating an additional space between the internal negative pressure-isolation space and the outside.

By varying the negative pressure-isolation space in this way, it is possible to safely and smoothly perform various treatments or procedures that were difficult to apply to patients with infectious diseases or suspected patients in the prior art. Even if the negative pressure-isolation space is reduced, the surrounding area including the face of the patient A is continuously shielded by being surrounded by the fixed cover 100 and the variable cover 300 and maintained at a lower pressure than the outside, so that external contamination by droplets or aerosols is prevented. The risk is greatly reduced, allowing the medical staff to take the necessary action more safely and accurately. For example, as shown in (a) of FIG. 7 , it is possible to expose the body of the patient A and perform CPR on an emergency patient suspected of having an infectious disease, or to deliver childbirth while protecting the fetus of an infected mother. In addition, precise and complex procedures such as respiratory-related treatment of patient (A), angiography, and various procedures requiring endoscopy can also be performed through the patient ( It can be performed by accessing A) and various procedures can be performed very smoothly by adjusting and exposing the required part of the variable cover 300 . In addition, since the risk of infection is reduced by the negative pressure-isolation space tailored to the patient (A), it is possible to simplify the protective equipment of the medical staff and enable a more accurate operation. As described above, the medical staff (B) inserts both arms into the first treatment tools (110a, 110b), approaches from the parietal side of the patient (A), and can perform the procedure conveniently, and faces the gaze direction (refer to the dotted arrow) Through the light-transmitting surface 130 made of the arranged inclined surface, the patient (A) is observed more clearly, and the operation can be performed closer to the patient (A). Even in this process, it can be safely protected from droplets or aerosols generated by the patient A through the fixed cover 100 . As described above, the negative pressure chamber 1 for isolating infectious diseases of the present invention can be easily installed for each bed to greatly increase the actual number of negative pressure beds, and can be disassembled and applied to other beds. In addition, since the negative pressure-isolation space can be maintained even if the bed in which the negative pressure chamber is installed is moved, various tests can be performed more smoothly even in a ward that is not equipped with an isolation facility.

Hereinafter, another embodiment of the present invention will be described in detail with reference to FIGS. 8 to 10 . For the sake of concise and clear description, the part different from the above-described embodiment will be mainly described, and the description of the part not mentioned separately will be replaced with the above-mentioned description.

Referring to FIG. 8 , the patient-customized negative pressure chamber 1-1 for isolation of infectious diseases according to another embodiment of the present invention includes variable covers 300-1a and 300-1b of different shapes, any one of them. is formed to be selectively coupled to the fixed cover 100 . The variable cover (300-1a, 300-1b) and the fixed cover (100) may be formed with a removable coupling part 150 as described above, and using this, the variable covers (300-1a, 300-1b) of different shapes are formed. ) can be used interchangeably. The variable cover (300-1a, 300-1b) may include a variable cover (300-1a) having a relatively small area and a variable cover (300-1b) having a relatively large area, and a variable cover having a different shape, not shown. can also be included. For example, any one of the variable covers (300-1a) may be in a relatively concise shape that can be freely bent, folded or unfolded, and the other variable cover (300-1b) is a fixed cover (100). ) It can be formed to be foldable in the form of a corrugated pipe or bellows because it is greatly extended outward and has a long length. In another embodiment of the present invention, the fixed cover 100 and the support plate 200 may be formed integrally with each other and may not be detachably formed. This is another example in which the fixed cover 100 and the support plate 200 are connected, and even in such a case, the above-described installation process can be performed by appropriately assisting the patient.

The negative pressure chamber 1-1 for isolating infectious diseases according to another embodiment of the present invention is structurally different and may be used according to the purpose as illustrated in FIGS. 9 and 10 . By combining the variable cover (300-1b) of a concise form that can be relatively freely refracted, folded, or unfolded, the exposed body portion of the patient (A) can be increased as shown in FIG. 9, and the bulky variable cover (300) -1b) may be combined to form a negative pressure-isolation space accommodating the entire body of the patient A as shown in FIG. 10 . In the case of FIG. 9 , the variable cover 300-1a is freely deformed into a shape more suitable for the posture or body type of the patient A using the close contact part 310 at the end of the variable cover 300-1a, and various corresponding A shielding structure of the form can be formed. In the case of FIG. 10 , it effectively acts like an independent negative pressure ward for one person, so that the entire body of the patient A is completely accommodated in the negative pressure-isolation space to more effectively respond to the spread of infectious agents. However, even in the case of FIG. 10 , since the variable cover 300-1b can be modified as much as necessary, the sound pressure-isolation space can be appropriately adjusted and used accordingly.

Hereinafter, another embodiment of the present invention will be described in detail with reference to FIG. 11 . For the sake of concise and clear description, the part different from the above-described embodiment will be mainly described, and the description of the part not mentioned separately will be replaced with the above-mentioned description.
