Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments.

[0037] In a radiation accident, the diffusion and contamination of radioactive substances or materials can cause radioactive harm to a certain range of personnel groups, and in order to timely block the continuous harm of radiation, it is necessary to wash and rescue the personnel as soon as possible.

[0038] Waste water is generated during washing and rescue, and the waste water is discharged from the medical rescue cabin through the drain pipe network 201, in order to avoid the leakage of gas in the cabin through the drain pipe network 201, resulting in the loss of pressure of the medical rescue cabin, the related technology sets a water seal structure in the drain pipe network 201.

[0039] However, the water seal structure used in the related technology is mostly a non-detachable U-shaped pipe, which needs to be cleaned and maintained through the drain port at the bottom of the U-shaped pipe, and there is a lack of suitable connecting structure at the drain port, which is inconvenient when connecting external pipelines, and the operation is relatively cumbersome.

[0040] The embodiments of the present application will be described below in combination with Figures 1 to 3 The embodiments of the present application will be described below in combination with

[0041] Referring toFigure 1 、 Figure 2 and Figure 3 According to the embodiment of the utility model, provide a kind of drainage device for medical rescue cabin, including drainage pipe network 201, drain valve 202 and water storage pipe 203, drainage pipe network 201 is set in the cabin body 1 of medical rescue cabin, to collect the waste water generated in the use process of medical rescue cabin, drainage pipe network 201 includes first water inlet and first water outlet, one end of drain valve 202 is connected first water outlet, water storage pipe 203 includes second water inlet and second water outlet, second water inlet is detachably connected with the other end of drain valve 202, and second water outlet is higher than second water inlet in vertical direction.

[0042] In medical rescue process, drain valve 202 is in open state, water storage pipe 203 is connected with external collecting pipe 3, and waste water generated by medical rescue cabin enters drainage pipe network 201 and is discharged from the second water outlet of water storage pipe 203. Since second water outlet is higher than second water inlet in vertical direction, part of waste water will be left in water storage pipe 203 and drainage pipe network 201 under the action of gravity, to form water seal effect.

[0043] When cleaning and maintenance are needed, first, drain valve 202 is closed, water storage pipe 203 is removed from drain valve 202, so that drainage pipe network 201 loses water seal, then collecting pipe 3 is connected to drain valve 202, and drain valve 202 is reopened, so that waste water stored in drainage pipe network 201 is discharged.

[0044] According to the drainage device for medical rescue cabin of the utility model, second water outlet is higher than second water inlet in vertical direction, water seal can be formed in water storage pipe 203 during daily use, pressure maintaining effect is generated, and pressure leakage is avoided. By adopting detachable water storage pipe 203, and setting the position of water storage pipe 203 at the end of drainage route, when cleaning and maintenance are needed, only need to remove water storage pipe 203, and connecting collecting pipe 3 to drain valve 202 again, water seal in drainage route can be eliminated, so that waste water can be smoothly discharged. In the process of dismounting, drain valve 202 is in closed state, so as not to discharge waste water uncontrollably. Therefore, the utility model can make drainage pipe network 201 of medical rescue cabin more easily cleaned and maintained.

[0045] It can be understood that the height of water seal determines the pressure in drainage pipe network 201 during drainage. Only when the cabin pressure (unit conversion is millimeter water column) is greater than the height of water seal, the gas in the cabin can push away the water seal and be discharged outside the cabin through the drainage device for medical rescue cabin.

[0046] In some embodiments, the height of the water seal is greater than the water column height corresponding to the rated maximum positive pressure of the medical rescue cabin. By designing a height difference greater than the water column height corresponding to the rated maximum positive pressure, the water storage pipe 203 can generate a water seal effect higher than the rated maximum positive pressure, ensuring that the gas in the cabin 1 cannot be discharged through the drainage pipe network 201, but can only be discharged through the designed gas discharge route, which helps to manage and control the gas in the medical rescue cabin.

[0047] Exemplarily, in some embodiments, the rated maximum positive pressure of the medical rescue cabin is 300 Pa (i.e., 30 mm of water column), and at this time, the height of the water seal can be controlled between 5 cm and 8 cm. On the one hand, setting a safety margin of at least 2 cm can cope with pressure fluctuations that occur during use, and more effectively ensure that the gas in the cabin 1 cannot be discharged through the drainage pipe network 201; on the other hand, the height does not exceed 8 cm, which can also avoid the accumulation of too much waste water in the drainage pipe network 201.

[0048] Referring to Figure 2 and Figure 3 In some embodiments, the second water inlet and / or the second water outlet are provided with quick-release joints. Using quick-release joints can facilitate the installation and disassembly of the water storage pipe 203, and help to simplify the daily cleaning and maintenance steps and time consumption of the medical rescue cabin.

[0049] The specific form of the quick-release joint can be selected from the commonly used specifications in the related art according to the connection mode of the pipeline. Exemplarily, in the embodiment shown in Figure 2 , the shape of the second water outlet is designed as a bell joint, which is suitable for connecting with the collection pipe 3 of the hose type. Other selectable specifications and matching connection modes can refer to the related art, which will not be described here.

[0050] It should be pointed out that in the related art, since the drainage port of the U-shaped pipe is located at the bottom and vertically downward, sufficient space needs to be left below the U-shaped pipe to connect the collection pipe 3 and the drainage port together, which is not conducive to the structural design of the medical rescue cabin. Moreover, after connection, the collection pipe 3 needs to be bent to a horizontal state. If the collection pipe 3 is a hard pipe, the turning radius is difficult to compress, resulting in further increase of the space to be left. If the collection pipe 3 is a hose, the bending part is prone to have a reduced cross-sectional area, hindering the flow of waste water.

[0051] Referring to Figure 2 and Figure 3In some embodiments, the water storage pipe 203 comprises a first section 2031, a second section 2032 and a third section 2033 connected in sequence, the second water inlet is located at the first section 2031, the second water outlet is located at the third section 2033, the first section 2031 and the third section 2033 extend horizontally, and the third section 2033 is higher than the first section 2031. By using the horizontally extending first section 2031 and the third section 2033, the water storage pipe 203 and the drain valve 202 are docked, and the water storage pipe 203 and the external collection pipe 3 are docked, so that the drainage device for the medical rescue cabin is more convenient to use.

[0052] In some embodiments, the height of the water storage pipe 203 monotonically increases from the second water inlet to the second water outlet. Wherein, the monotonic increase means that the height of any two points selected on the axis of the water storage pipe 203 relative to the point far away from the second water inlet must not be lower than the point close to the second water inlet. Exemplarily, in the embodiment shown in the drawings, the height of the second section 2032 is greater than the height of the first section 2031. Figure 3 In the embodiment shown in the drawings, the second section 2032 extends obliquely between the first section 2031 and the third section 2033, thereby producing the effect of monotonic increase.

[0053] In the U-shaped pipe used in the related art, impurities carried in the wastewater often deposit and adhere near the drain port, and there is a problem that it is difficult to clean. The water storage pipe 203 of the utility model adopts a monotonic increase shape design, compared with the conventional U-shaped pipe, can make more waste in the water to deposit in the position of the water storage pipe 203 close to the second water inlet, thereby facilitating the cleaning and maintenance of the water storage pipe 203 after disassembly, and reducing the residue of the dirt.

[0054] And at this time, the second water inlet is the lowest point of the water storage pipe 203, and the height of the water seal is the height difference between the second water inlet and the second water outlet. Therefore, the water storage pipe 203 can be designed to have a height difference between the second water inlet and the second water outlet greater than the water column height corresponding to the rated maximum positive pressure of the medical rescue cabin, thereby providing a suitable water seal effect. Here, the height difference can be approximately estimated by the theoretical distance between the corresponding points of the second water inlet and the second water outlet on the axis of the water storage pipe 203.

[0055] In some embodiments, the height of the drain pipe network 201 monotonically increases from the first water outlet to the first water inlet. By using the monotonic increase design, the wastewater can naturally flow to the first water outlet under the action of gravity, avoiding the existence of wastewater residue in the drain pipe network 201. At the same time, this can also ensure that the drainage device for the medical rescue cabin only forms a water seal at the water storage pipe 203, thereby facilitating daily use and maintenance.

[0056] In some embodiments, the drain network 201 comprises a main pipeline 2011 and branch pipelines 2012, the first water inlet is located on the branch pipeline 2012, the first water inlet is used for connecting the water outlet of the cabin 1, the number of the branch pipelines 2012 is at least two, each branch pipeline 2012 is connected in parallel to the main pipeline 2011, and the first water outlet is located on the main pipeline 2011.

[0057] Exemplarily, referring to Figure 1 , the cabin 1 of the medical rescue cabin is arranged with water facilities such as a shower room and a hand washing table, and the water facilities are respectively provided with water outlets, the medical rescue cabin has a plurality of water outlets, waste water generated by each water outlet is collected to the main pipeline 2011 through the branch pipeline 2012, and then is uniformly discharged through the main pipeline 2011, so that the drain device for the medical rescue cabin only needs to be provided with a single water storage pipe 203 to meet the pressure maintaining requirements of all the water outlets, and the structure design of the drain device for the medical rescue cabin is facilitated to be simplified.

[0058] In some embodiments, the drain device for the medical rescue cabin further comprises a filter screen 204, and the filter screen 204 is arranged between the first water inlet and the water outlet. The filter screen 204 can filter the hair, clothes debris and other large-size sundries in the waste water, so as to avoid the blockage of the drain network 201 in use.

[0059] In some embodiments, the main pipeline 2011 penetrates out of the side wall of the cabin 1, and the first water outlet is located outside the cabin 1. The first water outlet is located outside the cabin 1, so that the water storage pipe 203 and the drain valve 202 are located outside the cabin 1, on the one hand, the operation space outside the cabin 1 is more spacious, and cleaning and maintenance are facilitated, and on the other hand, the maintenance personnel do not need to enter the cabin during the cleaning and maintenance process, so that pollution is avoided to the environment in the cabin.

[0060] During transportation, the water storage pipe 203 can be detached for transportation, but the drain valve 202 is inconvenient to detach, so the drain valve 202 and the drain network 201 need to be transported integrally with the cabin 1, and at this time, the drain valve 202 has a risk of being damaged by collision.

[0061] Therefore, in some embodiments, the drain valve 202 is arranged in the accommodation groove of the side wall. During transportation of the medical rescue cabin, the water storage pipe 203 is placed independently after being detached, and the drain valve 202 and the drain network 201 are transported integrally with the cabin 1, and since the drain valve 202 is located in the accommodation groove, the drain valve 202 can be prevented from being collided during transportation, and the use safety of the drain device for the medical rescue cabin is improved.

[0062] The utility model also provides a medical rescue cabin, the medical rescue cabin comprises the drain device for the medical rescue cabin provided by the utility model.

[0063] Although the embodiments of the present application are described in conjunction with the drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes fall within the scope of the appended claims.
