Description

Technical Field

[0001] The invention belongs to auxiliary treatment equipment for hospitals, in particular to a patient pollution source gas suction and exhaust device assembled on bedside medical care equipment. Background Art

[0002] Since the viruses carried by infectious disease patients are highly contagious, hospitals will set up special infectious disease areas to treat such patients. In the prior art, an air inlet is set at one end of the ward in the infectious disease area, and an exhaust vent is set on the other wall, so that the whole ward forms a negative pressure space where fresh clean air flows from one side to the other. Although this method can solve the problem of clean air in the ward, due to the large space of the ward, the distance and time required for fresh air to bring viruses and bacteria into the exhaust vent are relatively long, and the patient's pollution source gas cannot be discharged from the exhaust vent in time. Viruses and bacteria will remain in the ward for a period of time. At the same time, viruses and bacteria will remain in the ward for a period of time. The area where bacteria flow with negative pressure airflow is larger, which will also form a high-risk area for medical staff to be infected. Moreover, in the process of medical staff treating patients, such as oral and nasal intubation, wound intubation, etc., when they need to face the patient's mouth, nose or wound at close range, the virus- and bacteria-containing gases discharged from the patient's mouth, nose or wound will directly splash into the working range of the medical staff, and the gas discharged by the ventilator placed on the bedside medical equipment cannot be quickly and promptly sucked out of the room, thereby increasing the infection risk of medical staff. This makes it difficult to ensure the protection and safety of medical staff when treating patients, and will also increase the chance of repeated infection of patients. Summary of the invention

[0003] The purpose of the present invention is to provide a patient contamination source gas suction and exhaust device installed on bedside medical care equipment, through which not only the patient contamination source gas can be quickly sucked and disinfected and sterilized and discharged to the outside at a close distance, but also the gas discharged from the exhaust port of the ventilator can be timely sucked and disinfected and sterilized and discharged to the outside in the daily care process, thereby reducing the risk of medical staff being infected by the patient contamination source gas and the gas discharged from the exhaust port of the ventilator during the treatment and daily care of the patients, and facilitating maintenance.

[0016] The main advantages and beneficial effects of the present invention are:

[0017] 1. In the technical solution of the present invention, the suction system is equipped with a patient pollution source gas suction component and a ventilator exhaust suction component. The suction pipe I and the suction pipe II in the patient pollution source gas suction component and the ventilator exhaust suction component are respectively fixed by a movable joint arm and a support frame, or are fixed by themselves using a universal tube structure. They can be moved and fixed at multiple angles and directions. Moreover, the patient pollution source gas suction hood and the ventilator exhaust suction hood are movably connected to the suction pipe I and the suction pipe II. The patient pollution source gas suction hood and the ventilator exhaust suction hood themselves can also rotate and move. Therefore, when medical staff are treating patients, they can quickly move and fix the patient pollution source gas suction hood to be close to the patient's facial features and wound positions, so that the gas discharged from the patient's facial features and wounds can be sucked into the patient pollution source at the first time. The gas is sucked into the hood and transported to the disinfection and sterilization device for disinfection and sterilization in cooperation with the electric air valve Ⅰ, the suction connecting pipe Ⅰ and the exhaust fan, and then discharged to the outside. In addition, in daily care, the gas discharged from the exhaust port of the ventilator can also be promptly transported to the disinfection and sterilization device for disinfection and sterilization by the exhaust suction hood of the ventilator in cooperation with the electric air valve Ⅱ, the suction connecting pipe Ⅱ and the exhaust fan, and then discharged to the outside, so that a local negative pressure suction area closest to the patient's contamination source gas and the exhaust port of the ventilator is formed, reducing the risk of infection for medical staff during close contact with patients during treatment and daily care, improving the safety of medical staff in treating patients with infectious diseases, and also reducing the risk of repeated infection of patients. In addition, safety nets Ⅰ and Ⅱ can prevent objects other than exhaust gas from being sucked into the pipeline, thereby ensuring the stability and safety of the device during operation.

[0018] 2. By adopting the technical solution of the present invention, a detachable condensate collection device is provided under the electric air valve II. In daily use, the accumulated water formed in the electric air valve I and the electric air valve II and the suction pipe I and the suction pipe II can be stored in the device. After a certain capacity is accumulated, the accumulated water can be removed and poured out. In this way, daily maintenance and cleaning of the equipment is convenient, and the stability of the equipment operation is further guaranteed. Disinfection and sterilization solution can be added to the condensate collection device. In this way, viruses and bacteria in the accumulated water can be killed in daily use, reducing the residual amount of viruses and bacteria in the equipment and improving the safety of equipment use.

[0019] 3. In the technical solution of the present invention, the size of the flow area of ​​the patient's pollution source gas and the gas discharged from the ventilator exhaust port with the negative pressure airflow is effectively reduced, so that the medical staff can move safely in the ward in a larger range, thereby purifying the air in the infectious disease ward, and providing a new solution for air purification in the infectious disease ward.

[0020] 4. Due to the adoption of the technical solution of the present invention, when the patient pollution source gas suction component and the ventilator exhaust suction component are not in use, the suction ports of the electric air valve I and the electric air valve II can be closed, thereby blocking the backflow of the bacteria-carrying exhaust gas remaining in the suction connecting pipe I and the suction connecting pipe II, further improving the safety during use. Daily cleaning and disinfection of the electric air valve I, the electric air valve II and the suction connecting pipe I can be carried out by ultraviolet sterilization or spraying disinfectant, which is simple to clean and maintain.

[0021] 5. In the technical solution of the present invention, the corresponding suction pipes of the patient pollution source gas suction hood and the ventilator exhaust suction hood are connected to the pollution source gas extraction system through the connection port I and the connection port II respectively, and are quick and movable connection structures, which can be easily disassembled, so that the patient pollution source gas suction hood and the ventilator exhaust suction hood and the corresponding suction pipes of the two can be disinfected and cleaned separately, and the existing commercially available disinfection device (such as ozone disinfector, etc.) can be directly connected through the connection port I and the connection port II to disinfect and clean the electric air valve I and the electric air valve II and the suction connection pipeline, which is convenient for daily disinfection, maintenance and replacement.

[0022] 6. The technical solution of the invention has a simple structure and a small size. According to the clinical use needs of the hospital, it can be directly installed in the cavity of the existing bedside medical equipment (such as floor-standing / suspended medical workstations, floor-standing / suspended medical columns, medical suspension bridges, medical pendants, etc.) by opening a hole, or it can be assembled in the cavity of the medical equipment through an assembly plate. It is suitable for use in hospital infections, infectious disease areas, intensive care units and other wards in need in the hospital. It is easy to assemble, convenient for procurement and assembly by the hospital, and is also beneficial for promotion and use in various hospitals. BRIEF DESCRIPTION OF THE DRAWINGS
