[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0033] To address the problem in existing technologies where, when ward space is limited, an electric sliding door is typically installed at the ward entrance to open and close the entrance, avoiding the space occupied by a revolving door. A transparent observation window is installed on the sliding door to observe the patient's condition in real time. However, since the door is usually not directly facing the bed and the area of the transparent observation window is limited, it is inconvenient for outsiders to visit the patient inside. This utility model provides a bone marrow transplant ward that places the external transparent window in the sliding stroke of the external sliding door, avoiding additional space occupation. It can be used when ward space is limited, and the external transparent window expands the field of vision for outsiders, making it easier for outsiders to visit the patient inside, improving convenience. Moreover, the structure is simple and cost-effective.
[0034] Please see Figure 1 and Figure 2 , Figure 1 and Figure 2 This is a schematic diagram of the bone marrow transplant ward structure of the present invention. The bone marrow transplant ward includes a clean room 1, an external transparent window 2, an external guide structure 3, and an external sliding door 4. The clean room 1 has an external observation opening 1a and an external passage opening 1b on its side wall, and the external observation opening 1a and the external passage opening 1b are located on the same side wall of the clean room 1. The external transparent window 2 is located at the external observation opening 1a. The external guide structure 3 is located in the clean room 1 and extends from the external passage opening 1b to the external observation opening 1a. The external sliding door 4 is slidably located on the external guide structure 3, and its sliding direction is the same as the extension direction of the external guide structure 3. When sliding, it can open and close the external passage opening 1b, and when the external passage opening 1b is opened, it slides at least partially to the external observation opening 1a.
[0035] In the bone marrow transplant ward provided by this utility model, since the outer transparent window 2 and the outer access opening 1b are located on the same side wall of the clean room 1, when the outer sliding door 4 is opened, the outer sliding door 4 slides along the outer guide structure 3 toward the outer transparent window 2 to open the outer access opening 1b, facilitating medical personnel to enter the clean room 1 for medical care. Furthermore, when the outer access opening 1b is opened, the outer sliding door 4 at least partially obscures the outer transparent window 2. When the outer sliding door 4 closes the access opening, it offsets the outer transparent window 2, allowing people outside to view the patient inside through the outer transparent window 2.
[0036] Thus, in this solution, the external transparent window 2 is at least partially located in the sliding stroke of the external sliding door 4, reducing the additional space occupied and making it easier to apply in situations where ward space is limited. Furthermore, the external transparent window 2 expands the field of vision for people outside, making it easier for them to visit patients inside, thus improving convenience. In addition, the structure is simple and cost-effective.
[0037] In one embodiment, the length of the outer sliding door 4 in its sliding direction is a; the length of the outer observation port 1a in the extension direction of the outer guide structure 3 is b, and the distance between the outer observation port 1a and the outer passage port 1b is c, satisfying that b+c≤a.
[0038] In this embodiment, the length of the outer sliding door 4 is set as described above, so that when the outer sliding door 4 slides to open the outer passage 1b, it can completely cover the position of the outer transparent window 2. That is, when the outer sliding door 4 opens the outer passage 1b, the outer sliding door 4 completely blocks the outer transparent window 2, so that the outer transparent window 2 falls entirely within the sliding stroke of the outer sliding door 4, avoiding the outer transparent window 2 occupying extra space. In this way, it is ensured that the outer sliding door 4 completely covers the outer observation opening 1a when opened, improving compactness and saving space. It should be noted that in this embodiment, the outer observation opening 1a and the outer passage 1b are arranged sequentially along the horizontal direction.
[0039] In one embodiment, the length of the external observation port 1a in the extension direction of the external guide structure 3 is greater than its distance from the external passage port 1b.
[0040] In this embodiment, the length of the external observation port 1a is set to be greater than its distance from the external passage port 1b, so as to maximize the installation area of the external transparent window 2 and further expand the field of vision for outdoor personnel. It should be noted that in this embodiment, the external sliding door 4 is set as a glass door.
[0041] In addition, it should be noted that the outer guide structure 3 can be configured as a guide arm, guide rail or other forms.
[0042] In one embodiment, the outer guide structure 3 includes an outer guide seat 31, which is located in the clean room 1 and extends from the outer passage 1b to the outer observation port 1a, and is provided with an outer guide groove along its extension direction; the outer sliding door 4 is slidably disposed in the outer guide groove.
[0043] In this embodiment, the outer sliding door 4 is slidably disposed in the guide groove of the guide seat to guide the outer sliding door 4 to slide, thereby improving the sliding stability of the outer sliding door 4. It should be noted that, in one embodiment, a drive mechanism is provided corresponding to the outer sliding door 4. This drive structure can be in the form of a drive motor, a drive wheel, and a transmission belt with teeth, and a foot switch and a touch switch are correspondingly provided. The specific drive structure and principle are existing technologies and will not be described in detail here.
[0044] In one embodiment, the bone marrow transplant ward further includes an isolation wall 5, which is located within a clean room 1 and horizontally divides the clean room 1 into an anteroom 11 and a ward room 12. The anteroom 5 has an internal observation port 5a and an internal passage port 5b. The external observation port 1a and the external passage port 1b are located on the side of the anteroom 11 opposite to the isolation wall 5. The bone marrow transplant ward also includes an internal transparent window 8, an internal guide structure 6, and an internal sliding door 7. The internal transparent window 8 is located at the internal observation port 5a. The internal guide structure 6 is located on the isolation wall 5 and extends from the internal passage port 5b to the internal observation port 5a. The internal sliding door 7 is slidably located on the internal guide structure 6, and its sliding direction is the same as the extension direction of the internal guide structure 6. When sliding, it can open and close the internal passage port 5b, and when the internal passage port 5b is opened, it slides at least partially to the internal observation port 5a.
[0045] In this embodiment, the cleanroom 1 is divided into an anteroom 11 and a ward room 12 by an isolation wall 5, thus forming a three-level space with the external corridor: corridor (Class 10,000) - anteroom 11 (Class 1,000) - ward room 12 (Class 100). This allows external personnel to undergo initial handwashing upon entering the clean area, and upon entering anteroom 11, they can utilize the handwashing facilities within anteroom 11 for secondary sterilization before entering ward room 12, further enhancing the cleanliness of ward room 12. Transparent windows are also installed in anteroom 11 and the isolation wall 5 to facilitate visitation by external personnel while maintaining the cleanliness of ward room 12.
[0046] It should be noted that the inner sliding door 7 and the inner guide structure 6 are set in the same way as the outer sliding door 4 and the outer guide structure 3.
[0047] In one embodiment, the ward room 12 is provided with a bed area 121, and the bed area 121, the inner observation port 5a and the outer observation port 1a are arranged on the same straight line.
[0048] In this embodiment, the bed area 121, the internal observation port 5a, and the external observation port 1a are arranged on the same straight line, facilitating direct observation of the patient by external personnel and improving convenience. It should be noted that in one embodiment, an infusion port is provided between the anteroom 11 and the ward room 12, i.e., an infusion port is provided on the isolation wall 5, facilitating infusion by medical staff in the anteroom 11 and improving the sterility of the ward room 12. Correspondingly, an openable and closable door is provided at the infusion port.
[0049] Furthermore, it should be noted that in one embodiment, a shelf 9 is provided in the anteroom 11 for placing medical supplies and facilitating the preparation of medicines needed for patient treatment by medical staff; and a hand sanitizing area is provided at the external access point 1b. In addition, a portable toilet is provided in the ward room 12, and a video device is installed; at least one equipment belt is provided against the wall in the bed area 121.
[0050] In one embodiment, the ward room 12 has an internal air supply vent at the top and two sets of internal air return vents 1c at the bottom, the two sets of internal air return vents 1c being located on both sides of the ward room 12 in the direction of extension of the bed area 121.
[0051] In this embodiment, the internal return air inlet 1c is located on both sides of the bed area 121 in the extension direction, so that the return air can simultaneously form a vertical flow and a horizontal laminar flow, reducing the discomfort to the patient.
[0052] In one embodiment, each group has multiple internal return air vents 1c, and the multiple internal return air vents 1c in the same group are spaced apart along the direction close to the anteroom 11.
[0053] In this embodiment, multiple internal return air inlets 1c are arranged at intervals as described above to ensure uniform air return.
[0054] In one embodiment, the ward room 12 has an internal return air duct interlayer 13 and an internal exhaust air duct interlayer 14 on both sides of the bed area 121 extending direction. Each internal exhaust air duct interlayer 14 has an exhaust vent that connects to the ward room 12 and is separated from the internal return air duct interlayer 13. The internal return air vent 1c of each group connects to the corresponding internal return air duct interlayer 13.
[0055] In this embodiment, the exhaust duct interlayer and the return air duct interlayer are separated to avoid cross-contamination and improve the cleanliness of ward 12. Furthermore, the exhaust vents allow for periodic exhaust, thereby delivering fresh air and improving the comfort of ward 12. It also provides some sound insulation.
[0056] In one embodiment, the top of the anteroom 11 is provided with an external air supply vent 11a, and the bottom of its side wall is provided with an external air return vent 11b. The external air supply vent 11a is located at the position of the external passage 1b of the anteroom 11.
[0057] In this embodiment, air supply and return vents are also provided in the anteroom 11, making the air supply system of the anteroom 11 independent from that of the ward room 12. Simultaneously, the external air supply vent 11a is placed at the external passage 1b, so that when the external passage 1b is opened, the air supplied by the air supply vent can disperse outwards, preventing external airflow from entering the anteroom 11. In one embodiment, a micromanometer is provided in the anteroom 11. Furthermore, solenoid valves are installed at each air supply vent, return vent, and exhaust vent.
[0058] To better understand this utility model, the following is combined with... Figure 1 and Figure 2 The technical solution of this utility model is described in detail below:
[0059] This design features a unidirectional airflow layout from the corridor to anteroom 11 and then to ward room 12, with cleanliness levels arranged as follows: corridor (Class 10,000), anteroom 11 (Class 1,000), and ward room 12 (Class 100). Furthermore, when multiple ward rooms are arranged sequentially, a relative positive pressure flow is maintained between adjacent rooms, with higher-level cleanliness rooms relative to lower-level cleanliness rooms, ensuring unidirectional airflow.
[0060] Furthermore, in this case, the treatment anteroom 11 serves as a buffer zone between the clean corridor and the ward room 12. On the one hand, after medical staff change shoes, clothes, and put on caps in the medical staff office area, they need to change shoes and clothes again in the anteroom 11 before entering the ward room 12, and return via the same route after finishing their work. On the other hand, medical staff can prepare for infusion and other corresponding nursing work in the anteroom 11, and can also monitor the patient's condition at all times through the observation window, minimizing the number of times medical staff enter the ward room.
[0061] Given the limited area, when the ward room 12 is small, a vertical airflow system is set up, that is, ceiling air supply and bottom return air. The air is relatively uniform in all sections of the room. The top supply and side return mode makes the patient feel more comfortable in the room.
[0062] This design offers the following advantages: the ductwork layer on the side wall of the ward facilitates installation and maintenance, provides some sound insulation, improves ventilation efficiency, and places the air supply outlets on the ceiling and the return air outlets on the bottom along the long side, reducing the impact of indoor airflow circulation on patients and ensuring uniform airflow distribution within the ward.
[0063] Furthermore, the ward can be laid out in a rectangular shape to reduce unsanitary corners, and only a hospital bed, a portable toilet, and a smart TV can be placed inside, maximizing the use of ward space and reducing the potential pollution caused by furniture.
[0064] In addition, an observation window and an infusion port are set between the anteroom 11 and the ward room 12 to minimize the number of times medical staff enter the ward and reduce the risk of cross-infection.
[0065] This allows for floor plan layout according to the minimum area specified in the standards, filling the current gap in the industry for setting up laminar flow wards in small spaces.
[0066] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
