Technical Field
[0001] This utility model relates to the field of medical care, specifically an embedded negative pressure drying workbench. Background Technology
[0002] In the nursing process of tubular instruments, high-pressure air guns are used after cleaning and disinfecting tubular instruments. The nozzle of the high-pressure air gun is inserted into one end of the tubular instrument, such as an endoscope or catheter. Through instantaneous or continuous high-pressure gas impact, the surface tension and capillary force of the liquid on the inner wall of the lumen are overcome, and the moisture remaining inside the lumen is blown out from the other end, thereby achieving rapid and thorough drying of the instrument's inner cavity.
[0003] After tubular instruments are treated by a cleaning and disinfection machine, the outer surface of the tubing is quickly dried, but some moisture may remain on the inner wall of the lumen. This residual moisture can hinder the penetration of sterilizing steam, leading to sterilization failure. Currently, manual operation of a high-pressure air gun for drying is commonly used. The process involves the operator transferring the tubular instruments to a dedicated air gun operating table, then picking them up one by one and blowing them into the lumen opening. This step must be repeated for each instrument. The process is cumbersome, time-consuming, and labor-intensive. Furthermore, the angle, force, and time of blowing depend on manual control, making it difficult to standardize and prone to uneven drying or blind spots, which in turn affects the drying quality and sterilization safety. Utility Model Content
[0004] To overcome the shortcomings of existing technologies, after tubular instruments are treated by a cleaning and disinfection machine, the outer surface of the tubing is quickly dried, but some moisture easily remains on the inner wall of the lumen. This residual moisture can hinder the penetration of sterilizing steam, leading to sterilization failure. Currently, manual operation of a high-pressure air gun for drying is commonly used. The process involves the operator transferring the tubular instruments to a dedicated air gun operating table, then picking them up one by one and blowing them dry at the lumen opening. This step must be repeated for each instrument, which is cumbersome, time-consuming, and labor-intensive. Furthermore, the angle, force, and time of blowing depend on manual control, making it difficult to standardize and prone to uneven drying or blind spots, thus affecting the drying quality and sterilization safety.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0017] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail. This application discloses an embedded negative pressure drying workbench. (Refer to...) Figure 1 , Figure 2 and Figure 3 An embedded negative pressure drying workbench includes an operating table 1, a cover plate 3 that is rotatably connected to the top of the operating table 1 via a hinge, and a drying mechanism 2 that is provided on the inner wall of the operating table 1. The drying mechanism 2 includes several tubes 201, which are fixedly connected to the inner wall of the operating table 1. Each tube 201 has a perforated plate 206 fixedly connected to its bottom. A vacuum pump 202 and a gas-water separator 203 are fixedly connected to the inner wall of the operating table 1. The outlet of the gas-water separator 203 extends to the outside of the operating table 1. The inlet of the vacuum pump 202 is fixedly connected to the outlet of the gas-water separator 203. A negative pressure pipe 204 is installed inside the operating table 1. The inlet of the gas-water separator 203 is fixedly connected to one end of the negative pressure pipe 204. A diversion pipe 205 is fixedly connected to the surface of the negative pressure pipe 204. The number of diversion pipes 205 matches the number of tubes 201. One end of the diverter tube 205 is fixedly connected to the bottom of the perforated plate 206. By setting the drying mechanism 2, the instrument is placed inside the tube body 201. The vacuum pump 202 is started to generate negative pressure, which is conducted to the bottom of the tube body 201 through the diverter tube 205 to form a negative pressure environment. Under the suction action, the moisture on the inner wall of the instrument evaporates rapidly. Some of the condensate enters the negative pressure tube 204 with the airflow. Water and gas are separated by the gas-water separator 203. The moisture is collected and the gas is discharged. The uniform drying of the inner walls of multiple instruments is completed at one time. The negative pressure environment lowers the boiling point of water, promotes the rapid evaporation of moisture from the inner wall of the instrument, and makes the drying more thorough. The airflow distribution is uniform and reasonable, avoiding local residue or splashing pollution caused by traditional blowing drying methods, improving the drying speed, shortening the processing time, and improving work efficiency.
[0018] Reference Figure 2 A sealing cover 4 is fixedly connected to the inner wall of the cover plate 3. One side of the sealing cover 4 contacts the top of the tube body 201. There are several sealing covers 4. By setting the sealing cover 4, after the cover plate 3 is closed, the sealing cover 4 automatically presses the top opening of the tube body 201 to achieve the sealing of the tube body 201. During the negative pressure drying process, it prevents external air leakage and ensures the stability of the negative pressure environment inside the tube body 201. Reference Figure 2 A sealing ring 5 is fixedly connected to one side of several sealing caps 4. One side of the sealing ring 5 contacts the top of the tube body 201. Through the setting of the sealing ring 5, the sealing ring 5 will generate elastic deformation after being pressed, filling the gap between the sealing cap 4 and the tube body 201, enhancing the tightness of the closure between the sealing cap 4 and the tube body 201, and preventing gas leakage during negative pressure operation. Reference Figure 2 A guide plate 6 is fixedly connected to the inner wall of the operating table 1. The guide plate 6 is set at an inclination. Several diversion pipes 205 all penetrate into the inner wall of the guide plate 6. Through the setting of the guide plate 6, some of the condensate flowing out from the perforated plate 206 can be discharged to prevent the condensate from accumulating at the bottom of the pipe body 201. The guide plate 6 is set at an inclination, and the condensate flows out naturally by gravity to prevent the growth of bacteria at the bottom of the pipe body 201. Reference Figure 4A drain pipe 7 is fixedly connected to the inner wall of the operating table 1. One end of the drain pipe 7 passes through the inner wall of the operating table 1 and extends to the outside. A valve is installed in the inner cavity of the drain pipe 7. One end of the guide plate 6 passes through the inner wall of the drain pipe 7. Through the setting of the drain pipe 7, the condensate collected by the guide plate 6 can be directly discharged. When discharging, simply open the valve on the drain pipe 7 to achieve rapid discharge of condensate. Reference Figure 3 The inner walls of several tubes 201 are provided with spiral plates 8. One end of the spiral plate 8 is fixedly connected to the top of the perforated plate 206. The spiral plates 8 provide support and guidance for the flexible tube when the instrument is inserted into the tube 201, preventing the flexible tube from bending or collapsing due to its own weight or airflow disturbance during the negative pressure drying process. Reference Figure 4 The bottom of the guide plate 6 is fixedly connected to a fixing block 9. There are several fixing blocks 9. The surface of the negative pressure pipe 204 is in contact with the inner wall of the fixing block 9. The negative pressure pipe 204 is fixedly connected to the bottom of the guide plate 6 through the fixing block 9. By setting the fixing block 9, the negative pressure pipe 204 can be fixed and supported, ensuring the stability of the negative pressure pipe 204 and preventing the negative pressure pipe 204 from falling.
[0019] Working principle: When the inner wall of a tubular instrument needs to be dried, the user first opens the cover plate 3. The cover plate 3 is opened by rotating the hinge, revealing the drying area of multiple tubes 201 below. The tubes 201 have different diameters to accommodate tubular instruments of different sizes. Then, the tubular instruments with residual moisture after cleaning are inserted one by one into the corresponding tubes 201. The tubes 201 are equipped with spiral plates 8, which can provide support and guidance for the flexible tubing, leaving airflow channels inside the tubes 201, which is conducive to the uniform evaporation of moisture. The tubular instruments are inserted into the tubes 201. Afterwards, the lower end of the tubular instrument contacts the perforated plate 206, and then the cover plate 3 is closed. After the cover plate 3 is closed, the sealing cap 4 on the inner wall will automatically press against the opening at the top of the tube body 201. By compressing and deforming the sealing ring 5, the tube body 201 can be sealed. The user starts the vacuum pump 202 through an external control switch. The vacuum pump 202 is powered by an external power supply. The high-speed rotation of the internal components of the vacuum pump 202 generates a partial vacuum in the pump chamber, which reduces the air pressure at the air inlet of the vacuum pump 202, thereby drawing in air from the outside. This is existing technology and will not be elaborated further. The air inlet of 202 is connected to the air outlet of the air-water separator 203. The air inlet of the air-water separator 203 is connected to the negative pressure pipe 204. The negative pressure is transmitted from the air-water separator 203 to the negative pressure pipe 204 and the distribution pipe 205, and then evenly introduced into the bottom of each tube 201 through the distribution pipe 205, so that a stable negative pressure environment is quickly formed inside the entire tube 201. Under the negative pressure environment, the boiling point of water is lowered, which can accelerate the evaporation of moisture on the surface and inside the tube of the tubular instrument. The humid air flows upward and outward under the guidance of the airflow, and some of the condensate passes through the gap of the perforated plate 206 under the action of gravity. Water falls to the bottom of pipe 201 and is automatically collected to drain pipe 7 via guide plate 6. The accumulated water can be discharged by opening the valve on drain pipe 7. Another part of the condensate and humid air enter the air-water separator 203 through the diverter pipe 205 with the negative pressure airflow. Water and air are separated in the air-water separator 203. The water is collected in the water collection container of the air-water separator 203. The water can be automatically discharged by controlling the valve at the outlet of the water collection container. The dried gas is discharged through the outlet of vacuum pump 202. The cover plate 3 and the sealing cover 4 are both made of transparent material, which makes it easy to observe the internal drying status.
[0020] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
