Description

Technical Field

[0001] The utility model relates to the technical field of disinfection instruments, in particular to a flow sensor disinfection device. Background Art

[0002] In modern clinical medicine, ventilators are an effective means of artificially replacing autonomous ventilation functions. They are vital medical devices that can prevent and treat respiratory failure, reduce complications, and save and prolong patients' lives. Flow sensors, as an important component of the ventilator's airway system, mainly monitor pressure and flow during the use of the ventilator. There are many types of flow sensors, including hot wire, crystal thermal film, differential pressure, and pressure sensing. If the flow sensor is not properly maintained and disinfected during daily use, it will not only damage the components, but also cause cross infection and even endanger the safety of patients using the ventilator.

[0003] At present, flow sensors need to be disinfected by soaking in alcohol after use, and then wait for natural drying. However, in actual work, there are a series of problems such as cumbersome operation and untimely turnover. For example, for a disinfection box that has been immersed and disinfected, other flow sensors that need to be disinfected cannot be added. These flow sensors that need to be disinfected can only be placed and wait or use another disinfection box. Therefore, multiple disinfection boxes are needed to be disinfected at the same time to improve the turnover rate of flow sensors, but this will inevitably bring a huge workload to nursing staff.

[0038] like Figure 1 As shown, the moving mechanism includes a three-dimensional CNC platform, which is provided with an X-axis screw rod moving guide rail 2, a Z-axis screw rod moving guide rail 3 and two Y-axis screw rod moving guide rails 1.

[0041] like Figure 3 As shown, a cooling zone is provided under the moving mechanism, and the cooling zone is used to place the flow sensor; the cooling zone is provided with a cooling mechanism 12, and the cooling mechanism 12 includes a cooling fan and a cooling plate. The cooling fan cools the flow sensor to be sterilized, and the cooling plate is used to provide a cold source for the cooling fan.

[0042] The disinfection mechanism comprises an alcohol container 13, which is arranged at one side of the cooling zone. The alcohol container 13 contains alcohol, and the flow sensor is placed in the alcohol container 13 for disinfection. Preferably, the alcohol is 75% alcohol.

[0043] The cleaning mechanism includes an injection water container 16, which is arranged on a side of the alcohol container 13 away from the cooling zone. The injection water container 16 contains injection water, and the flow sensor is placed in the injection water container 16 for disinfection and cleaning.

[0044] A drying area 19 is provided between the injection water container 16 and the storage mechanism. A heating module 20 is installed in the drying area 19. The heating module 20 is used to dry the cleaned flow sensor.

[0045] The storage mechanism includes a standby placement basket 21, the bottom of which is an inclined structure, so that the flow sensor is pushed down to the bottom of the standby placement basket 21 and then tilted and separated from the sensor placement rack 11, and rolls along the bottom inclined structure of the standby placement basket 21 into the standby placement basket 21. Preferably, the standby placement basket 21 is made of stainless steel.

[0046] The alcohol container 13, the injection water container 16 and the standby basket 21 are all provided with a top cover, and one side of the top cover is provided with infrared sensors corresponding to the alcohol container 13, the injection water container 16 and the standby basket 21, respectively. The infrared sensors are used to sense when the flow sensor reaches the top of the top cover, and control the opening or closing of the corresponding top cover.

[0047] The working principle of the utility model is as follows: in normal use, the flow sensor of the ventilator is first placed in the cooling zone for cooling, and then one of the process channels of the disinfection device is started, the clamping mechanism moves to the cooling zone along the screw rod moving guide rail 2 in the X-axis direction and the screw rod moving guide rail 1 in the Y-axis direction, the clamp 4 moves downward along the screw rod moving guide rail 3 in the Z-axis direction, reaches the top of the sensor placement rack 11, and approaches the handle 9 of the sensor placement rack 11, the air pump is started to make the clamp 4 contract and clamp the handle 9 of the sensor placement rack 11, and then the clamp 4 moves upward along the screw rod moving guide rail 3 in the Z-axis direction; the clamp 4 moves on the screw rod moving guide rail 2 in the X-axis direction to move the sensor placement rack 11 loaded with the flow sensor to the top of the alcohol container 13. When the first infrared sensor 15 senses the sensor placement rack 11 above, the top cover 14 of the alcohol container is controlled to open. The clamp 4 moves the sensor rack 11 down into the alcohol container 13 along the screw rod moving guide rail 3 in the Z-axis direction, and then the clamp 4 releases the sensor rack 11 and moves upward. At this time, the top cover 14 of the alcohol container is automatically closed. After 60 minutes of alcohol soaking, the clamp 4 moves downward, and the first infrared sensor 15 controls the top cover 14 of the alcohol container to open. The clamp 4 clamps the handle 9 of the sensor rack 11 and moves upward; the clamp 4 continues to move along the screw rod moving guide rail 2 in the X-axis direction and reaches above the injection water container 16. When the second infrared sensor 18 senses the sensor rack 11 above, it controls the top cover 17 of the injection water container to open. At this time, the clamp 4 moves downward along the screw rod moving guide rail 3 in the Z-axis direction, and puts the sensor rack 11 loaded with the flow sensor into the injection water container 16 until the injection water submerges the flow sensor. Then the fixture 4 moves up and down three times to clean the alcohol on the flow sensor, and then the fixture 4 moves up along the Z-axis spiral rod moving guide rail 3. The fixture 4 continues to move along the X-axis spiral rod moving guide rail 2 to the drying area 19 with the sensor placement rack 11 and the flow sensor. The heating module 20 in the drying area 19 dries the flow sensor for 10 minutes. After the time is up, the fixture 4 moves up along the Z-axis spiral rod moving guide rail 3, and then moves along the X-axis spiral rod moving guide rail 2 to the top of the standby placement basket 21. At this time, after the third infrared sensor 22 senses the sensor placement rack 11 above, it controls the top cover 23 of the standby placement basket to open, and then the fixture 4 moves downward along the Z-axis direction spiral rod moving guide rail 3 to put the sensor placement rack 11 into the standby placement basket 21. When it moves to a certain position, the bottom of the flow sensor touches the standby placement basket 21 and tilts, thereby separating from the sensor placement rack 11, sliding to the bottom of the standby placement basket 21 through the ramp at the bottom of the sensor placement rack 11, and the fixture 4 clamps the empty sensor placement rack 11 and moves upward along the Z-axis direction spiral rod moving guide rail 3. At this time, the top cover 23 of the standby placement basket is automatically covered.Finally, the fixture 4 moves the guide rail 2 along the X-axis direction to return to the starting end of the process channel to disinfect the next flow sensor.

[0048] When the flow sensor in the process channel is soaked in alcohol, the clamping mechanism can move to another process channel along the screw rod moving guide rail 2 in the X-axis direction and the screw rod moving guide rail 1 in the Y-axis direction to grab another flow sensor for disinfection. In this way, multiple flow sensors can be disinfected simultaneously through different process channels, and flow sensors in different positions can be taken and placed. The cooling, soaking, cleaning, drying and placement of the flow sensors are completely automatically performed by the program, which effectively reduces the workload of nursing staff, improves the turnover rate of flow sensors, and avoids unnecessary damage to the flow sensors.

[0049] The main functions of the utility model: when in use, the moving mechanism can simultaneously perform flow sensor disinfection operations on multiple process channels. First, the flow sensor to be disinfected is cooled and placed in the placement mechanism. The moving mechanism controls the movement of the clamping mechanism. The clamping mechanism grabs the placement mechanism and moves it to the top of the disinfection mechanism. The placement mechanism is placed in the disinfection mechanism to disinfect the flow sensor. After the disinfection is completed, the moving mechanism moves the disinfected flow sensor together with the placement mechanism to the top of the cleaning mechanism, and then places the placement mechanism in the cleaning mechanism to clean the flow sensor. Finally, the moving mechanism moves the cleaned flow sensor together with the placement mechanism to the top of the storage mechanism, and places the flow sensor in the storage mechanism. The utility model enables multiple flow sensors to perform disinfection tasks simultaneously through different process channels, avoiding confusion when nursing staff perform multiple disinfection tasks at the same time, thereby reducing the workload of nursing staff; improving the turnover rate of flow sensors.
