Specifically, referring to fig. 1 and 2, the van 100 includes a van body 110 having an inner chamber 111, and an isolation door 120 disposed in the van body 110, the isolation door 120 isolates the inner chamber 111 of the van body into a first isolation treatment chamber 111a and a second isolation treatment chamber 111b, a medical treatment facility is disposed in the first isolation treatment chamber 111a, a sterilization facility is disposed in the second isolation treatment chamber 111b, and the air suction structure 200 includes a germ filtering suction fan 210 disposed on an inner wall of the second isolation treatment chamber 111b, and a filter screen structure 220 disposed on the isolation door 120, the germ filtering suction fan 210 is configured to draw and filter air in the first isolation treatment chamber 111a, and the filter screen structure 220 is configured to filter air entering the second isolation treatment chamber 111a from the second isolation treatment chamber 111 b. It should be noted that the germ filtering and exhausting fan 210 is a mature existing device, and mainly includes an air pumping pipeline, an air pumping unit, a filtering and sterilizing unit, and an air outlet, air enters from the air pumping pipeline under the air pumping action of the air pumping unit, and is exhausted from the air outlet after passing through the filtering and sterilizing unit, the air pumping unit is generally an air pump or an exhaust fan, the filtering and sterilizing unit can be a material capable of adsorbing and filtering germs, and can also be a sterilizing system for sterilizing germs passing through the unit by ultraviolet rays, high temperature or medicines for killing germs.

It should be noted that, referring to fig. 3 and 4, the isolation door 120 is not completely isolated, so as to facilitate air suction and maintain a good air environment in the isolation ward, an air inlet 121 and an air suction opening may be formed in the isolation door 120, a filter screen structure 220 is installed at the air inlet 121, and a filter hole of the filter screen structure 220 communicates with the isolation treatment room 111a and the buffer sterilization room 111 b; an air suction pipeline of a germ filtering exhaust fan 210 is arranged at the air suction port 122, and the lumen of the air suction pipeline is communicated with the isolated medical treatment room 111 a. Therefore, the air internal circulation effect in the carriage is better, the air circulation of the medical treatment room 111a is isolated, and the rehabilitation of the patient is facilitated.

Furthermore, the isolation door 120 is further provided with a water and electricity pipeline port 123, and the water and electricity pipeline port 123 is used for leading the water and electricity pipeline from the buffering sterilization room 111b to the isolation medical treatment room 111 a. Medical equipment and patients in the isolated treatment room 111a need to be powered by water in daily life, so that the isolating door 120 can be provided with a water and electricity pipeline port 123 to meet the requirement.

Moreover, in order to improve the sealing performance of the isolation door 120 at the corner of the door, the isolation effect is enhanced, and the virus propagation is prevented. The gap portion of the water and electricity line inlet on the isolation door 120 needs to be sealed, and a sealant, a sealing wax or a foam structure can be filled in the air inlet 121, the suction opening 122 and the water and electricity line opening 123. Further, the four sides of the isolation door 120 may be adhesively fixed to the bottom, top and sides of the vehicle compartment by using a sealant. The material may be any material that can provide a sealing effect without departing from the essence of the present invention, and therefore, is not limited herein.

Further, the partition door 120 may be provided as a panel door detachably installed in the freight box 110. The plate is a common section bar in the building engineering, the isolation door 120 is arranged by the plate, on one hand, the material is easy to obtain, on the other hand, the technical scheme is simple, and the construction is convenient.

The isolation door 120 can be set as a temporary simple door, and the manufacturing method of the temporary simple door is flexible. Specifically, the van-type wagon compartment is formed by cutting and processing plates according to the size of the van-type wagon compartment. The temporary easy door includes a door frame, a lintel, a door bottom, and a curtain 120 a. Specifically, a door frame is directly cut out of a wood board for manufacturing the temporary simple door, a lintel and a door bottom are reserved, the door curtain 120a is fixed on the lintel, the door curtain 120a in a naturally sagging state can play a role in closing the isolation door 120, and only the door curtain 120a needs to be lifted when the isolation door 120 is opened. In this solution, the reason for the preservation of the lintel and the bottom is that the lintel is used to fix the upper edge of the curtain 120a, it is possible to glue the upper part of the curtain 120a to the lintel or to nail it, while the bottom functions as: if the lowest end of the door curtain 120a is just higher than the bottom of the carriage and lower than the upper edge of the door bottom when the door curtain 120a naturally sags, the door curtain 120a can play a better sealing role; if there is no door bottom, the door curtain 120a will not seal because it is higher than the bottom of the car, or will not seal because the door curtain 120a is too long to sweep over the bottom of the car. The door curtain 120a can be set to be a whole piece of windproof soft material, and under the negative pressure effect of air in the negative pressure isolation ward, the door curtain 120a can tightly cover and press on the isolation door 120, so that on one hand, a better isolation sealing effect can be achieved, and on the other hand, the transparent door curtain 120a can also greatly improve the lighting of the ward, so as to build a comfortable ward environment. This solution is a simpler but front lighting embodiment. In addition, the isolation door 120 is provided with a soft door curtain 120a, so that the space utilization rate in the isolation ward can be further improved. In the traditional technical scheme, the door leaf is arranged in various forms, and mainly comprises a hinged door leaf and a sliding door, but the hinged door leaf and the sliding door have the defects respectively. It should be understood that if the hinged door leaf is arranged in the carriage of the van truck, the internal space of which is very compact, the space in the isolation ward can catch the elbow, so that medical facilities with larger volume cannot be placed, the inconvenience in use of the ward is brought, and the medical treatment and the treatment of patients are not facilitated; or a sliding door, although the sliding door does not occupy more space than the isolation door 120 provided with the door curtain 120a, the sliding door can only reach half of the width of the carriage at most, which is very disadvantageous to the medical facilities and medical staff. Therefore, the door curtain 120a is simple and convenient to arrange, the construction difficulty in the ward construction process is reduced, and more precious time is favorably used for treating the patient. Therefore, the soft transparent material adopted as the door curtain 120a in the invention is not only simple and easily available in material, but also can achieve better technical effect, and is a more preferable embodiment.

In addition, in order to conveniently and rapidly grasp the state of illness of the patient and the dynamic state of the ward in real time, the isolating door 120 can be provided with a viewing window, and the viewing window can be provided with a transparent viewing structure which can be made of transparent toughened glass, transparent plastic plates and the like. Medical personnel can inspect the internal condition without entering the isolated medical treatment room 111a, thereby preventing abnormal conditions and protecting the life safety of patients.

The carriage of the van 100 has a large height above the ground, so that medical staff cannot get in and out conveniently. Referring to fig. 5, for this purpose, a platform structure 300 may be disposed at the rear of the van 100 for medical staff to enter and exit the van 100. Specifically, the housing platform structure 300 may include a support bracket 310a disposed at the rear of the van 100, and a first support plate 310b disposed on the support bracket 310a, where a height of the first support plate 310b corresponds to a height of the van body 110, and the support bracket 310a may be a rectangular parallelepiped support bracket 310 a. The entrance ramp 320 comprises a second supporting plate which is obliquely arranged from the ground to the top of the supporting frame 310a and is correspondingly connected to one side of the first supporting plate 310 b; the departure ramp 330 includes a third supporting plate inclined from the top of the supporting frame 310a to the ground, and the third supporting plate is correspondingly connected to the other side of the first supporting plate 310 b. Furthermore, a trapezoidal support frame can be arranged below the second support plate and the third support plate, so that the bearing capacity of the second support plate and the third support plate is further improved, and the stability of the ward access passage is ensured. It should be noted that, on the basis of not deviating from the essence of the present invention, the platform 310 for entering room, the ramp 320 for entering room, and the ramp 330 for exiting room are provided in many ways, as long as the arrangement form for facilitating the medical staff to enter and exit the ward is achieved, and the invention is not limited herein.

The invention also provides a cross infection prevention method for the negative pressure isolation ward 1000 transformed by the van 100, which comprises the following steps:

step S10, turning on the germ filtering exhaust fan 210, and pumping and filtering the air in the isolation treatment room 111a to the buffering sterilization room 111 b;

step S20, closing the carriage back door and opening the isolation door, enabling medical staff or patients to enter the buffer sterilizing room 111b, completing body surface sterilizing treatment in the buffer sterilizing room 111b, and then entering the isolation treatment room 111 a;

and step S30, closing the rear door of the carriage and opening the isolation door, enabling medical staff or patients to enter the buffering and sterilizing chamber 111b from the isolation treatment chamber 111a, and opening the rear door of the carriage and leaving the rear door after the buffering and sterilizing chamber 111b finishes body surface sterilizing, air sterilizing and object sterilizing treatment.

Therefore, in the process of getting in and out of the negative pressure isolation ward 1000 every time, medical staff or patients need to be disinfected, and through the disinfection and sterilization of the buffer disinfection and sterilization chamber 111b, viruses and germs can be effectively inactivated, prevented from being spread to the outside, and prevented from further infection and diffusion.

The negative pressure isolation ward 1000 reformed by the van 100 comprises the van 100 and an air suction filtration structure 200. The air suction structure 200 can pump air in the vehicle cabin, so that the air circulates in the vehicle cabin and viruses are not spread to the outside, and public safety is endangered. The van 100 is transformed into the negative pressure isolation ward 1000, so that the problems of insufficient medical resources and shortage of isolation wards can be effectively solved, and the life health safety of people can be protected.
