The present disclosure relates to the technical field of medical equipment, in particular to a hermetic tarpaulin device and a nursing room.
When patients with infectious diseases are treated, such patients need to be isolated to prevent the spread of the infectious virus to the outside world. Nowadays, patients with infectious diseases are generally transferred to wards formed by engineering construction methods such as hospitals. However, this kind of ward cannot be moved, and it takes a certain amount of time to transfer patients to the ward, which may delay the best time for treatment. Meanwhile, the cost of this kind of ward is high. In addition, when clustered infectious diseases occur, it is difficult for the ward to meet the use demand.
In the related art, there are some devices that can be temporarily constructed to form an isolation space to replace the above-mentioned wards. These devices generally consist of frames and canvas. When building, the frame is first unfolded into a structure that occupies a certain space, and then multiple pieces of canvas are connected to the unfolded frame, and the canvas and the frame together form a simple temporary ward. This kind of temporary ward has great defects in use. A lot of gaps exist between the connecting parts, especially when there is a severe infectious disease transmitted by aerosol, it is very easy for the infectious virus to spread to the outside world, so the isolation effect of the ward formed by the engineering construction method cannot be achieved.

The terms used herein in the specification of the present disclosure are only for the purpose of describing specific embodiments, and are not intended to limit the present disclosure. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.
The embodiments of the present disclosure provide a nursing room. The nursing room can be completely isolated from the outside world, which is suitable for nursing use of severe infectious diseases transmitted through aerosols, influenza-like infectious diseases, tuberculosis infectious diseases, unexplained infectious diseases, and frail and sick people.
In some embodiments of the present disclosure, as shown in
It can be understood that the specific number of support structures 100 can be determined according to actual needs. For example, in the embodiments below, the nursing room may include two support structures 100, and the nursing room may include four support structures 100. Besides, the nursing room can also have more composition modes, for example, it can include three support structures 100, or more support structures 100.
In some embodiments of the present disclosure, the nursing room is provided with the movable support structure 100. Therefore, when building the nursing room, it can be realized only by controlling the movement of the support structure 100, which is convenient to build. Compared with the ward formed by engineering construction, it can significantly reduce the cost and reduce the occupied space, and can achieve complete isolation from the outside world, thereby improving the isolation effect.
In an embodiment, as shown in
In this embodiment, the first support structure 110 and the second support structure 120 can approach or move away from each other, so as to release enough space between them to provide conditions for the hermetic tarpaulin device 200 to unfold.
It should be noted that the movement of the first support structure 110 and the second support structure 120 can be done manually, or by automatic control. When the latter is used, related control devices can be integrated and installed on the first support structure 110 and/or the second support structure 120.
In this embodiment, the hermetic tarpaulin device 200 includes a frame 210 and a tarpaulin body 220. The frame 210 can be unfolded or folded into a predetermined shape. The tarpaulin body 220 can be connected to the frame 210. When the frame 210 is unfolded, the tarpaulin body 220 can be unfolded to form a hermetic space completely isolated from an outside world, and when the frame 210 is folded, the tarpaulin body 220 can be folded into a whole.
It should be noted herein that the tarpaulin body 220 follows the frame 210 and performs related actions, and the corresponding actions of the frame 210 can be realized manually, for example, directly apply force to the frame 210 manually, or indirectly apply force to the frame 210 manually. For example, the frame 210 can be installed on the support structure 100 (the embodiments herein are mainly presented in this way), and the support structure 100 can be manually pushed to move, so as to realize the corresponding action of the frame 210. The corresponding action of the frame 210 can also be realized through automatic control, which can directly control the action of the frame 210 or indirectly control the action of the frame 210 through the support structure 100.
In some embodiments, the frame 210 includes a plurality of support rods. The support rods are installed on the first support structure 110 and the second support structure 120. By driving the first support structure 110 and the second support structure 120 to move, indirectly causing the support rods to perform corresponding actions, the arrangement of the frame 210 can be varied, which is not limited herein.
For ease of understanding, in some embodiments, as shown in
Thus, the arrangement and combination of the first support upright 211, the first support cross rod 213, the second support upright 212 and the second support cross rod 214 can play the role of propping up the tarpaulin body 220, and the structure is simple, and since the hermetic tarpaulin device 200 can form a hermetic space completely isolated from the outside world, the effect of isolation can also be improved.
Further, in some embodiments, a first diagonal rod 215 is provided between the first support upright 211 and the first support cross rod 213, and/or a second diagonal rod 216 is provided between the second support upright 212 and the second support cross rod 214.
Thus, the first diagonal rod 215 and/or the second diagonal rod 216 can enhance the structural strength, making the entire frame 210 more stable and reliable.
Further, in some embodiments, a third support cross rod 217 is provided between the first support cross rod 213 and the second support cross rod 214. The third support cross rod 217 plays the role of connection and reinforcement, making the whole frame 210 more stable in structure.
As shown in
When the first support upright 211 and the second support upright 212 are installed on the first support structure 110 and the second support structure 120 respectively, a better way is to enable the first support upright 211 and the second support upright 212 to unfold or fold correspondingly following the movement of the first support structure 110 and the second support structure 120. Thus, the first support upright 211 and the second support upright 212 can be installed when the first support structure 110 is close to the second support structure 120.
In some embodiments, the first support upright 211, the second support upright 212, the first support cross rod 213, the second support cross rod 214 and the third support cross rod 217 are telescopic rods or folding rods.
The above process can be understood with reference to
In some embodiments, as shown in
It should be noted herein that only the hexahedral structure is used as an example to illustrate the tarpaulin body 220, in other embodiments, the tarpaulin body 220 may form a pentahedral structure or other polyhedral structures.
For the tarpaulin body 220, at least one surface thereof includes at least one curtain, and the curtain can be moved to open or close the hermetical space.
It can be understood that the curtain can be separated from other parts of the tarpaulin body 220 (the base 221), and when the two are separated, the hermetical space can be opened.
In some embodiments, the tarpaulin body 220 includes a first curtain 222 and a second curtain 223. The first curtain 222 and the second curtain 223 are connected to the base 221. The first curtain 222 and the second curtain 223 can move away from and approach each other to open or close the hermetic space. The hermetic tarpaulin device 200 also includes a driving mechanism 230. The driving mechanism 230 is installed on the frame 210, for example, can be installed on the aforementioned third support cross rod 217, and it can also replace the third support cross rod 217. The driving mechanism 230 is for driving the first curtain 222 and the second curtain 223 to move.
Therefore, by driving the first curtain 222 and the second curtain 223 to move through the driving mechanism 230, the hermetic space can be quickly opened or closed without human intervention, saving time and effort.
In some embodiments, as shown in
In this embodiment, the first curtain slider 233 and the second curtain slider 235 respectively drive the first curtain 222 and the second curtain 223 to move. When the first curtain slider 233 and the second curtain slider 235 move away from each other, the first curtain 222 and the second curtain 223 open the hermetic space. When the first curtain slider 233 and the second curtain slider 235 approach each other, the first curtain 222 and the second curtain 223 enclose the hermetic space.
In some embodiments, the first slider driving assembly 234 includes a first driving motor 2341 and a first conveyor belt assembly 2342, the first curtain slider 233 is fixedly connected to the first conveyor belt assembly 2342, the second slider driving assembly 236 includes a second driving motor 2361 and a second conveyor belt assembly 2362, and the second curtain slider 235 is fixedly connected to the second conveyor belt assembly 2362.
Thus, the first curtain slider 233 and the second curtain slider 235 can be moved by driving the motor to rotate the conveyor belt assembly, thereby realizing the movement of the first curtain 222 and the second curtain 223.
Further, in order to facilitate installation, in some embodiments, the driving mechanism 230 may also include a first fixing member 237 and a second fixing member 238. The first fixing member 237 and the second fixing member 238 are fixedly installed on the frame 210 (for example, installed on the first support upright 211 and the second support upright 212 respectively), and the first fixing member 237 is opposite to the second fixing member 238. The first driving frame 231 is hinged to the first fixing member 237, and the second driving frame 232 is hinged to the second fixing member 238.
The driving mechanism 230 may include a first fixing member 237, a first driving frame 231, a second driving frame 232, a second fixing member 238, or the like. The first fixing member 237 and the second fixing member 238 are fixedly arranged. Between the first driving frame 231 and the first fixing member 237, between the first driving frame 231 and the second driving frame 232, and between the second driving frame 232 and the second fixing member 238 are hinged relationships. Therefore, the driving mechanism 230 has a folding effect, so that it can be folded into the first support structure 110 and the second support structure 120 along with the frame 210.
In some embodiments, a damping hinge 239 is connected between the first fixing member 237 and the first driving frame 231, between the first driving frame 231 and the second driving frame 232, and between the second driving frame 232 and the second fixing member 238. Thus, the above-mentioned folding effect can be better reflected.
The above process can be understood by referring to
When the above-mentioned driving mechanism 230 is used to move the curtain, the first curtain 222 and the second curtain 223 need to be designed accordingly, for example, it can be carried out in the following manner, cut along the “I” shape at the corresponding position of the base 221. For ease of understanding, as shown in
It should be pointed out that, the embodiments herein need to always provide a hermetical space completely isolated from the outside world. Therefore, in order to ensure the sealing effect, a magnetic attractor 224 is provided between the first curtain 222 and the second curtain 223, between the first curtain 222 and other surfaces, and between the second curtain 223 and other surfaces. The magnetic attractor 224 can provide suction force, such that when the first curtain 222 and the second curtain 223 approach, the first curtain 222, the second curtain 223 and the base 221 can be closely connected, to eliminate gaps between the first curtain 222, the second curtain 223 and the base 221, and between the first curtain 222 and the second curtain 223.
In some embodiments, the magnetic attractor 224 can be selected according to the material of the tarpaulin body 220. For example, when the tarpaulin body 220 is made of flexible materials such as PE/PVC/TPU, the magnetic attractor 224 can be soft magnets. For another example, when the tarpaulin body 220 is made of a relatively hard material, the magnetic attractor 224 can also be a permanent magnet or the like.
On the other hand, it can be seen from the foregoing description that the frame 210 can be installed on the first support structure 110 and the second support structure 120, the tarpaulin body 220 needs to be connected to the frame 210, so that the tarpaulin body 220 can also be unfolded when the frame 210 is unfolded.
For this, in an embodiment, please refer to
It can be understood that when the tarpaulin body 220 is fully unfolded, taking the hexahedron structure as an example, the interior does not necessarily form a regular shape. For example, as mentioned above, the support structure 100 also has the function of functional integration. Therefore, in some applications, an air intake system and an exhaust system may be provided on the support structure 100 to create a negative pressure environment in the hermetic space. Then, under the influence of the negative pressure, the bottom of the tarpaulin body 220 may be sunken.
For this, in an embodiment, as shown in
In another embodiment, the driving mechanism 230 includes an electric zipper (not shown) provided between the curtain and other surfaces. The electric zipper, for example, can be installed on the third support cross bar 217. The separation of the first curtain 222, the second curtain 223 and the base 221 is realized through the automatic opening and closing of the electric zipper.
In this embodiment, it should be understood that the magnetic attractor 224 in the foregoing embodiments can also be applied to ensure the sealing effect. For example, the magnetic attractor 224 may be provided between the first curtain 222 and the second curtain 223, between a lower side of the first curtain 222 and the base 221, and between a lower side of the second curtain 223 and the base 221.
In some other embodiments, ordinary zippers can also be provided between the first curtain 222 and the base 221, and between the second curtain 223 and the base 221, and the driving mechanism 230 can be designed as follows.
In an embodiment, as shown in
It should be noted herein that the first zipper is provided between the upper side of the first curtain 222 and the base 221, the second zipper is provided between the upper side of the second curtain 223 and the base 221. There are two parallel and independent slide rails in the first drive frame 231. The first curtain slider 233 and the first zipper closure 233a respectively move along a slide rail. There are also two parallel and independent slide rails in the second drive frame 232. The second curtain slider 235 and the second zipper closure 235a move along one slide rail, respectively.
In this embodiment, the first curtain slider 233 cooperates with the first zipper closure 233a to drive the first curtain 222 to move, and the second curtain slider 235 cooperates with the second zipper closure 235a to drive the second curtain 223 to move. The movement of the first curtain 222 is taken as an example herein. When the tarpaulin body 220 is in the unfolded state shown in
In some embodiments, the first zipper driving assembly 234a includes a third driving motor and a third conveyor belt assembly, and the first zipper closure 233a is fixedly connected to the third conveyor belt assembly. The second zipper driving assembly 236a includes a fourth driving motor and a fourth conveyor belt assembly, and the second zipper closure 235a is fixedly connected to the fourth conveyor belt assembly.
For other structural components of the driving mechanism 230 in this embodiment, reference may be made to the foregoing embodiments, which will not be repeated herein. The driving mechanism 230 in this embodiment can be understood as a modified form of the driving mechanism 230 in the preceding embodiments. It is only necessary to add the first zipper driving assembly 234a and the first zipper closure 233a on the first driving frame 231, and add the second zipper driving assembly 236a and the second zipper closure 235a on the second driving frame 232.
In another embodiment, as shown in
Different from the foregoing embodiments in which the first support structure 110 and the second support structure 120 are used to form the nursing room, in this embodiment, due to the adoption of four support structures 100, the performance of the nursing room in terms of stability will be more superior. More functions can be integrated by setting more support structures 100, for example, the above-mentioned air inlet system and air outlet system can be installed on the corresponding support structures 100, and even lockers and air-conditioning systems can also be installed.
It can be understood that the various frames 210 described above can be applied in the nursing room. For example, same as the previous embodiments, the frame 210 may include a first support upright 211 and a second support upright 212. The first support upright 211 is installed on the first support structure 110, and the second support upright 212 is installed on the second support structure 120.
In nursing rooms employing four support structures 100, the frame 210 can also be deformed.
For example, in some embodiments, as shown in
The function of the fourth support cross rod 218 is similar to the function of the third support cross rod 217, and plays the role of reinforcing the overall structural strength of the frame 210.
On the other hand, in the nursing room using four support structures 100, telescopic connecting frames 150 can also be provided between the support structures 100 (the telescopic connecting frame 150 can also be applied in the aforementioned nursing room using two supporting structures 100), such that the movement of the support structure 100 becomes more regulated, and the expansion and contraction of the nursing room will also be differentiated.
As shown in
In the embodiment in which the frame 210 is unfolded independently, the telescopic connecting frame 150 may also be directly provided between the support rods.
Here, please refer to
It should be noted that in the aforementioned nursing room using two support structures 100, designs including but not limited to those listed below have been made. The tarpaulin body 220 can adopt a hexahedron structure or other structures. The tarpaulin body 220 can include a first curtain 222 and a second curtain 223. In order to move the first curtain 222 and the second curtain 223, various driving mechanisms 230 are listed. It can be understood that the above designs can all be applied in the nursing room using four support structures 100. For example, the driving mechanism 230 can be designed integrally with the fourth support cross rod 218, or directly replace the fourth support cross rod 218.
The various technical features of the above-mentioned embodiments can be combined arbitrarily, and for the sake of concise description, all possible combinations of the various technical features in the above-mentioned embodiments are not described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as within the scope of the description.
The above-mentioned embodiments only express several implementation modes of the present disclosure, and the description thereof is relatively specific and detailed, but should not be construed as limiting the scope of the present disclosure. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present disclosure, and these all belong to the scope of the present disclosure. Therefore, the scope of the present disclosure should be based on the appended claims.
