Problems solved by technology

The positive pressure biological protection hood is mainly composed of the hood cover body, air supply pipeline, and power supply air filter device. In the early stage, disinfection is mainly carried out by soaking, spraying, wiping, etc. in disinfectant. At the same time, clean water is also required to remove the residual disinfectant. The process of washing, drying, and disinfection is extremely cumbersome, and there is a risk of operator exposure during the disinfection process
At the same time, in some biological safety protection facilities, such as negative pressure isolation wards, biological product workshops, etc., there are independent passages for personnel to enter and exit, and the putting on and taking off of positive pressure biological protection hoods are usually located in different rooms. Requires complex item transfer process

Embodiment 1

[0040] Such as Figure 1-Figure 5 As shown: this embodiment provides an integrated transmission fumigation device 100 for protective equipment, including a disinfection chamber 1, a generator 2, a disinfectant storage tank 3 and a first pipeline 4, and the disinfection chamber 1 is used to place the protective equipment to be disinfected. Utensil 49, generator 2, disinfectant storage tank 3 and first pipeline 4 are all located outside the disinfection chamber 1, generator 2 is arranged on the first pipeline 4, and both ends of the first pipeline 4 are connected to the disinfection chamber 1 is connected, the disinfectant storage tank 3 is used to hold the disinfectant, the disinfectant storage tank 3 is connected with the generator 2, and the disinfectant in the disinfectant storage tank 3 generates a disinfectant gas under the action of the generator 2, and passes through the first The pipeline 4 enters the disinfection chamber 1 to disinfect the protective equipment 49 to be...

Embodiment 2

[0055] This embodiment provides a disinfection method using the integrated transfer fumigation device 100 for protective equipment in Embodiment 1, including the following stages:

[0056] The first stage includes a ventilation process and a dehumidification process. First, the ventilation process is carried out, and then the ventilation process and the dehumidification process are carried out alternately until the temperature sensor 46 detects the temperature in the disinfection chamber 1 and the VHP sensor 47 detects the temperature in the disinfection chamber 1. The humidity reaches the set value, and at the same time, the generating device 2 works to preheat;

[0057] During the ventilation process, the compressed air enters the disinfection chamber 1 sequentially through the compressed air hand valve 33, the first pressure reducing valve 34, the first filter 35, the compressed air solenoid valve 36, and the air supply filter 23, and then passes through the outlet in sequen...

Abstract

The invention discloses an integrated transmission type protective appliance fumigation device and a disinfection method, and relates to the technical field of biological safety disinfection equipment. The integrated transmission type protective appliance fumigation device comprises a disinfection chamber, a generation device, a disinfectant storage tank and a first pipeline. The disinfection chamber is used for containing a to-be-disinfected protective appliance, and the generation device is arranged on the first pipeline; the two ends of the first pipeline communicate with the disinfection chamber, the disinfectant storage tank is used for containing disinfectant, the disinfectant storage tank communicates with the generation device, the disinfectant in the disinfectant storage tank generates disinfection gas under the action of the generation device, and the disinfection gas enters the disinfection chamber through the first pipeline to disinfect the to-be-disinfected protective appliance. The disinfection chamber comprises a first transfer door and a second transfer door, the first transfer door is connected with the clean area, the second transfer door is connected with the polluted area, the first transfer door and the second transfer door can achieve interlocking sealing, and the first transfer door and the second transfer door cannot be opened at the same time. According to the invention, full-automatic comprehensive disinfection of the to-be-disinfected protective device can be realized, and the disinfection process and the transfer process are simplified.

Description

technical field [0001] The invention relates to the technical field of biological safety disinfection equipment, in particular to an integrated transfer fumigation device and disinfection method for protective equipment. Background technique [0002] Disinfection and sterilization of protective equipment is a necessary prerequisite for repeated use. Taking the positive pressure biological protection hood as an example, the positive pressure biological protection hood is a reusable personal protective equipment that can provide a high level of safety protection for the head and respiratory tract of personnel. During the process of handling pathogenic microorganisms, the positive pressure biological protection hood is extremely susceptible to contamination by pathogenic microorganisms, and usually needs to be fully disinfected after use before it can be used safely by others again. The positive pressure biological protection hood is mainly composed of the hood cover body, air...
