Description

Technical Field

[0001] This utility model relates to the field of disinfection products, and in particular to a cleaning tank for cleaning and steam cleaning special infection instruments. Background Technology

[0002] The hospital's central sterilization supply room (CSSM) is responsible for cleaning and sterilizing many reusable hospital supplies. Water sinks are common items in CSSMs; placing items to be cleaned into the sink and rinsing them is a routine task.

[0003] Common hospital sterilization supply room sinks are basically the same in structure as ordinary household sinks, including a sink frame, sink body, and drain pipe. The sink body is installed on the sink frame, and the drain pipe is connected to the bottom of the sink body. A faucet can be installed on the sink frame and connected to a water supply line to supply cleaning water. A flexible hose is used to connect to the drain pipe and extend the hose into the sewer to achieve drainage.

[0004] Steam cleaners utilize high-temperature, high-pressure steam to rinse items, offering superior cleaning compared to water rinsing. They are commonly used for cleaning medical supplies. However, because steam rinsing also produces water, hospital sterilization supply rooms often place items to be cleaned in a water tank for steam rinsing. While steam rinsing is more effective than water rinsing, the steam rapidly cools and liquefies into water mist, which is difficult to dissipate within the sterilization supply room. Excessive water mist can disrupt normal operations. Furthermore, the water mist may contain germs from the items being rinsed, potentially allowing for aerosol transmission.

[0005] In addition, there are specific cleaning requirements for instruments infected with certain pathogens. For example, instruments infected with venereal bacteria require immersion in a 1 mol / L sodium hydroxide solution for 60 minutes followed by rinsing. Instruments infected with gas gangrene require immersion in a 1000 mg / L to 2000 mg / L chlorine-containing disinfectant for 30 to 45 minutes; if there is visibly soiled, immersion in a 5000 mg / L to 10000 mg / L chlorine-containing disinfectant for at least 60 minutes followed by rinsing. Because chlorine-containing disinfectants are volatile, and the volatile gases have adverse effects on humans, it is best to treat them if possible.

[0006] To avoid the aforementioned drawbacks of steam rinsing in hospital sterilization supply rooms, some hospital sterilization supply rooms have installed transparent covers over the water tanks, with operating holes for hands to enter. During steam rinsing, the transparent cover is placed over the water tank, and the steam pipes of the steam cleaner and the staff's hands are inserted into the transparent cover to perform the rinsing operation.

[0007] The transparent cover offers some protection against water mist; the mist adheres to the cover and forms small droplets that fall off, thus preventing water mist from spreading. However, water mist can still leak from the operating port, so it doesn't completely solve the problem. Furthermore, the transparent cover has no significant effect on preventing the adverse effects of chlorine-containing disinfectant evaporation. Utility Model Content

[0008] The technical problem to be solved by this utility model is to provide a water tank for a hospital disinfection supply room that can handle water mist generated by steam rinsing and volatile gases from cleaning agents.

[0009] The technical solution adopted to solve the above problems is as follows: a cleaning tank for cleaning special infected instruments and steam cleaning includes a main structure, which includes a tank frame, a tank body, and a drain pipe. The tank body is installed on the tank frame, and the drain pipe is connected to the bottom of the tank body. It also includes a gas handling device, which is located directly above the tank body and is height adjustable. The gas handling device includes a device housing, an exhaust fan, a water mist filter, and a harmful gas filter. The device housing includes a tank body cover and an air duct. The air duct is connected to the top of the tank body cover, and the exhaust fan, harmful gas filter, and water mist filter are arranged sequentially from top to bottom inside the air duct.

[0010] Furthermore, the hospital's disinfection supply room uses a water tank with a mounting frame, which is located behind the water mist treatment device. The mounting frame is connected to the water tank frame, and the water mist treatment device is installed on the mounting frame.

[0011] Furthermore, the mounting bracket includes a mounting bracket body, guide rods, screws, operating handles, threaded sleeves, and guide sleeves. The screws are vertically arranged, with both ends mounted on the mounting bracket body. The threaded sleeves are fitted onto the screws and threadedly connected to them. There are two guide rods, symmetrically arranged on the left and right sides of the screws. The guide sleeves are correspondingly set on each guide rod and fitted onto it. The water mist treatment device is connected to the threaded sleeves and guide sleeves.

[0012] Furthermore: the water mist treatment device includes a water collection bottle; the air duct is inclined and has an outward protrusion on the downward side of the air duct, the bottom of the outward protrusion forming a water collection trough; the water mist filter is correspondingly arranged with the water collection trough, and the downward projection of the water mist filter is located within the range of the water collection trough; the water collection bottle is located outside the air duct and is threadedly connected to the water collection trough.

[0013] Furthermore, the water mist treatment device includes a water guiding hose; the air duct is inclined and has an outward protrusion on the downward side, the bottom of which forms a water collection tank; the water mist filter is correspondingly arranged with the water collection tank, and the downward projection of the water mist filter is located within the range of the water collection tank; the upper end of the water guiding hose extends into the air duct and connects to the water collection tank, and the lower end of the water guiding hose extends into the water tank body.

[0014] Furthermore, the water mist treatment device includes a water guiding hose; the air duct is inclined and has an outward protrusion on the downward side of the air duct, and the bottom of the outward protrusion forms a water collection tank; the water mist filter is correspondingly arranged with the water collection tank, and the downward projection of the water mist filter is located within the range of the water collection tank; the upper end of the water guiding hose extends into the air duct and connects to the water collection tank, and the lower end of the water guiding hose passes through the water tank frame and connects to the drain pipe.

[0015] Furthermore, the main body of the water tank is transparent.

[0016] Furthermore, the harmful gas filter is an activated carbon filter.

[0017] The beneficial effects of this utility model are: when rinsing with water, the position of the water mist treatment device is adjusted to be higher, so that there is more space above the water tank, making it easier to rinse with water. The water rinsing method is the same as the prior art, which is to turn on the faucet installed on the water tank frame to rinse.

[0018] During steam rinsing, lower the water mist treatment device slightly to facilitate water mist extraction. Turn on the exhaust fan; the fan creates negative pressure inside the device housing to draw in the water mist. As the water mist passes through the water mist filter, small water droplets in the air cannot pass through. These small droplets are trapped by the filter and form larger droplets that fall down. This effectively handles the water mist generated during steam rinsing, preventing it from spreading throughout the disinfection supply room.

[0019] When cleaning special infection instruments, if the cleaning agent is volatile, the position of the water mist treatment device should be adjusted to a lower position. The exhaust fan will create negative pressure inside the device housing to draw in the cleaning agent vapors. The cleaning agent vapors will pass through the water mist filter and be absorbed by the harmful gas filter. Attached Figure Description

Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] like Figures 1 to 3 As shown, the cleaning tank for cleaning special infected instruments and steam cleaning includes a main structure 1. The main structure 1 includes a tank frame 11, a tank body 12, and a drain pipe 13. The tank body 12 is installed on the tank frame 11, and the drain pipe 13 is connected to the bottom of the tank body 12. It also includes a gas handling device 2, which is located directly above the tank body 12 and is height adjustable. The gas handling device 2 includes a device housing 21, an exhaust fan 22, a water mist filter 23, and a harmful gas filter 28. The device housing 21 includes a tank body cover 211 and an air duct 212. The air duct 212 is connected to the top of the tank body cover 211. The exhaust fan 22, the harmful gas filter 28, and the water mist filter 23 are arranged sequentially from top to bottom inside the air duct 212.

[0032] The main structure 1 can be the same as the existing water tank in a hospital's sterilization supply room. This utility model actually adds a water mist treatment device 2 and the mounting bracket 3 (described later) to the existing technology, i.e., the main structure 1. The exhaust fans 22 are all existing products and can be fixed inside the air duct 212 with fasteners. The water mist filter 23 is an existing technology product, also known as a demister, and is disclosed in some patents, such as the water mist filter disclosed in Chinese patent application number 202121867455.5. The harmful gas filter 28 also adopts existing technology, for example, a flat activated carbon filter can be used. The installation methods of the water mist filter 23 and the harmful gas filter 28 can be as follows: Figure 4As shown, positioning grooves 2122 are provided on the left and right inner sides of the air duct 212, and insertion holes 2121 are provided on the front side of the air duct 212. The water mist filter 23 and the harmful gas filter 28 are inserted into the positioning grooves 2122 through the insertion holes 2121. Sealing gaskets can be provided around the insertion holes 2121 to seal against the water mist filter 23 and the harmful gas filter 28, preventing gas and liquid leakage and also securing the water mist filter 23 and the harmful gas filter 28. To prevent the water mist treatment device 2 from obstructing the cleaning operation view when it descends, the main body cover 211 of the water tank can be made of a transparent material, such as a transparent plastic sheet.

[0033] The hospital's disinfection supply room has a water tank installed and fixed in place; a faucet is connected to the water tank frame 11, and the faucet is connected to the water supply pipe; a flexible hose is used to connect the drain pipe and extend the hose to the sewer; the plug of the exhaust fan 22 is connected to the power socket; this utility model is then ready for use.

[0034] When rinsing with water, raise the position of the water mist treatment device 2 to make the space above the water tank larger, so that water rinsing can be carried out more conveniently. The water rinsing method is the same as the existing technology, simply turn on the faucet installed on the water tank frame to rinse.

[0035] During steam rinsing, the water mist treatment device 2 should be lowered slightly to facilitate water mist extraction. Turn on the exhaust fan 22; the fan creates negative pressure within the device housing 21 to draw in the water mist. As the water mist passes through the water mist filter 23, small water droplets in the air are trapped and formed into larger droplets that fall down. This effectively treats the water mist generated during steam rinsing, preventing it from spreading throughout the disinfection supply room.

[0036] When cleaning special infection instruments, if the cleaning agent is volatile, the position of the water mist treatment device 2 should be adjusted to a lower position. The exhaust fan 22 will create negative pressure inside the device housing 21 to draw in the cleaning agent vapors. The cleaning agent vapors will pass through the water mist filter 23 and be absorbed by the harmful gas filter 28.

[0037] The water mist treatment device 2 needs to be installed and its height adjusted. The specific method is as follows: The hospital's disinfection supply room uses a water tank including a mounting frame 3. The mounting frame 3 is located behind the water mist treatment device 2 and is connected to the water tank frame 11. The water mist treatment device 2 is installed on the mounting frame 3. The mounting frame 3 includes a mounting frame body 31, guide rods 35, screws 32, an operating handle 34, threaded sleeves 33, and guide sleeves 36. The screws 32 are vertically oriented, with both ends mounted on the mounting frame body 31. The threaded sleeves 33 are fitted onto the screws 32 and threadedly connected to them. There are two guide rods 35, symmetrically arranged on the left and right sides of the screws 32. The guide sleeves 36 correspond one-to-one with the guide rods 35 and are fitted onto them. The water mist treatment device 2 is connected to the threaded sleeves 33 and guide sleeves 36.

[0038] The threaded sleeve 33 and the screw 32 form a screw-nut mechanism. Manually rotating the operating handle 34 will rotate the screw 32, which will drive the threaded sleeve 33 to move up and down, thus moving the water mist treatment device 2 up and down. The screw-nut mechanism composed of the threaded sleeve 33 and the screw 32 should be designed to have a self-locking effect to prevent the water mist treatment device 2 from automatically moving down due to gravity.

[0039] As mentioned earlier, in the operation of the first type of hospital disinfection supply room using a water tank, air passes through the water mist filter 23. Small water droplets in the air cannot pass through; instead, they are trapped by the water mist filter 23 and form larger droplets that fall down. These droplets drip from the air duct 212 into the water tank.

[0040] To better handle water droplets, this invention can be further improved as follows: Figure 5 and Figure 6 As shown, the water mist treatment device 2 includes a water collection bottle 24; an air duct 212 is inclined and has an outward protrusion 25 on the downward side of the air duct 212, and the bottom of the outward protrusion 25 forms a water collection trough 26; a water mist filter 23 is correspondingly arranged with the water collection trough 26, and the downward projection of the water mist filter 23 is located within the range of the water collection trough 26; the water collection bottle 24 is located outside the air duct 212 and is threadedly connected to the water collection trough 26.

[0041] Water droplets fall into the water collection tank 26 and then into the water collection bottle 24. Once the water collection bottle 24 is full, it is removed, the water is poured out, and then it is reinstalled.

[0042] It is also possible to Figure 7 and Figure 8As shown, the water mist treatment device 2 includes a water guiding hose 27; an air duct 212 is inclined and has an outward protrusion 25 on the downward side of the air duct 212, and the bottom of the outward protrusion 25 forms a water collection tank 26; a water mist filter 23 is correspondingly arranged with the water collection tank 26, and the downward projection of the water mist filter 23 is located within the range of the water collection tank 26; the upper end of the water guiding hose 27 extends into the air duct 212 and is connected to the water collection tank 26, and the lower end of the water guiding hose 27 extends into the water tank body 12.

[0043] Water droplets fall into the water collection tank 26 and are guided into the water tank body 12 through the water guide hose 27.

[0044] Other than that Figure 9 As shown, the water mist treatment device 2 includes a water guiding hose 27; an air duct 212 is inclined and has an outward protrusion 25 on the downward side of the air duct 212, and the bottom of the outward protrusion 25 forms a water collection tank 26; a water mist filter 23 is correspondingly arranged with the water collection tank 26, and the downward projection of the water mist filter 23 is located within the range of the water collection tank 26; the upper end of the water guiding hose 27 extends into the air duct 212 and is connected to the water collection tank 26, and the lower end of the water guiding hose 27 passes through the water tank frame 11 and is connected to the drain pipe 13.

[0045] Water droplets fall into the water collection tank 26 and are guided into the drain pipe 13 through the water guide hose 27.
