Abstract
Description
Technical Field
[0001] This utility model relates to the medical field, and in particular to a multi-channel time-controlled pressure drying device. Background Technology
[0002] The degree of dryness of instruments directly affects the success and effectiveness of the sterilization process. Laparoscopic instruments and flexible endoscopes are expensive and mostly reusable. After use, they need to be cleaned, disinfected, dried, and sterilized before they can be reused. Whether cleaned by a vacuum boiling washer or manually, laparoscopic instruments require manual drying afterward. A typical set of laparoscopic instruments contains anywhere from 7-8 to over 10 pieces, all of which are tubular instruments and require thorough drying, with each instrument requiring approximately 1-2 minutes of air drying. Flexible endoscopes have long tubular diameters (commonly 20mm). + -60 + Similarly, whether machine-cleaned or hand-cleaned, manual drying is required, which takes a long time (3-10 minutes). Existing handheld dryers can only manually dry each lumen instrument or flexible endoscope individually, making it difficult to control the drying time. In batches, the drying effect is uncontrollable and inefficient, making it difficult to achieve standardized drying quality. Incomplete drying leaves residual moisture, which can easily breed bacteria and even form biofilms, leading to hospital-acquired infections with serious consequences. Incomplete drying affects the sterilization process and quality, causing sterilization failure or wet packs, resulting in supply disruptions. Utility Model Content

[0021] The preferred embodiments of this utility model will be described in detail with reference to the accompanying drawings.
[0022] Figures 1 to 7 This is a preferred embodiment of a multi-channel time-controlled pressure drying device provided by this utility model. For example... Figures 1 to 7As shown, the multi-channel time-controlled pressure drying device includes an air compressor 10 and a drying cabinet 20 connected to the air compressor. The drying cabinet 20 includes a cabinet body 21 and a cabinet door 22. The cabinet body 21 is provided with a main pipe 23 connected to the internal pipes of the air compressor 10. A main control valve 231 is provided on the main pipe 23. The main pipe 23 is connected to multiple branch pipes 24. Each branch pipe 24 is provided with a diversion control solenoid valve 241 for controlling the on / off state. The main control valve 231 and the diversion control solenoid valve 241 are connected to the main control module. 30 connection, branch pipe 24 is connected to a blower hose 26; each branch pipe 24 is provided with an instrument clamp 25 for clamping the instrument and a hose clamp 27 for clamping the blower hose and aligning it with the through hole on the instrument on one side, and a pressure gauge 243 is connected to the branch pipe 24; the main pipe 23 is also connected to an external air blower pipe 244 for drying the outer surface of the instrument, and the outlet end of the external air blower pipe 244 is connected to an air curtain drying device 2441. The external air blower pipe 244 is located behind each blower hose 26, and the air curtain drying... The device 2441 is positioned above each instrument clamp 25. The cabinet door 22 is equipped with a main switch 221, branch pipe on / off switches 223 corresponding to each branch pipe, and a timer 224. All four switches are connected to the main control module 30. In use, the instrument clamps 25 are used to grip the instruments. The angle of the flexible hose clamp 27 is adjusted, and the flexible hose clamp 27 is used to clamp the air hose 26, aligning it with the through-hole on the instrument, to dry the inside of the instrument. The air curtain drying device 2441, positioned above each instrument clamp 25, can blow air onto the surface of each instrument to ensure it is dry. The pressure gauge 243 displays the pressure within the corresponding branch pipe 24. Simultaneously, the timer 224 controls the on / off state of the diversion control solenoid valve 241, allowing control of the blowing time and pressure according to different instruments. This allows for simultaneous air drying of multiple instruments, improving efficiency. It can also dry the outer surface of the instruments, ensuring thorough drying and meeting the requirements of medical settings for instrument safety and improved work efficiency. The timer 224 is a time relay. The bottom of the blower hose 26 is equipped with a nozzle. Depending on the different through holes on the instrument, the nozzle can be matched with a suitable connector and aligned with the through holes on the instrument.
[0023] like Figure 4 and Figure 5As shown, each instrument clamp 25 is mounted on a support 28, which is installed inside a cabinet 21. Each instrument clamp 25 includes a clamp base 251, a first clamp arm 252, a second clamp arm 253, and a clamping actuator 254 for driving the opening and closing of the first and second clamp arms. The first clamp arm 252 is mounted in the clamp base 251 via a first pivot, and the second clamp arm 252 is mounted in the clamp base 251 via a second pivot. An opening drive seat 255 for inserting between the first and second clamp arms to open them is connected to the linkage of the clamping actuator 254. A return spring 256 is provided between the first and second clamping arms 252 and 253. When it is necessary to open, the clamping driver 254 drives the opening drive seat 255 to insert between the first clamping arm 252 and the second clamping arm 253, pushing the first and second clamping arms 252 and 253 to rotate around their respective pivots, thus opening the first and second clamping arms 252 and 253 and placing the instrument between them. When it is necessary to close, the clamping driver 254 drives the opening drive seat 255 to return to its original position, and the first and second clamping arms 252 and 253 close under the action of the return spring 256, thus clamping the instrument. The clamping driver 254 of each instrument clamp 25 is connected to a main board, and the main board is connected to a clamping switch button 257, which is located inside the cabinet 21.
[0024] The cabinet 21 is also provided with a slide 28, and multiple slide seats 281 are fitted in the slide 28. Each slide seat 281 is connected to a hose clamp 27 via a cable 282, so that the hose clamp 27 can be moved according to the position of the instrument.
[0025] like Figure 6 As shown, a fixed seat 283 is installed at the bottom of the slide 281. The fixed seat 283 has at least six mounting slots, each containing a ball bearing 2831. A rotating seat 284 is fitted around the fixed seat 283. The rotating seat 284 has multiple positioning slots corresponding to the ball bearings 2831. The cable 282 is installed at the bottom of the rotating seat 284. This allows the rotating seat 284 to rotate around the fixed seat 283 according to the position of the through hole on the instrument, causing the angle of the flexible hose clamp 27 connected to the cable 282 to change, thus better aligning with the through hole on the instrument. The cable 282 can be made of engineering plastics, such as ABS (acrylonitrile-butadiene-styrene copolymer), PC (polycarbonate), or PP (polypropylene). These materials achieve torsional function through structural design (such as elastic arms and bending joints), utilizing the toughness and elastic deformation of the plastic itself to adjust the angle, and maintaining positioning by the material's resilience after the external force is removed.
[0026] The cabinet 21 is also equipped with a water receiving tray 29. When the instrument is dried by blowing air, water flows out of the instrument and falls into the water receiving tray 29.
[0027] Each branch pipe 24 is equipped with a pressure sensor 242, which is connected to the main control module 30. The main control module 30 is also connected to the frequency converter in the air compressor 10. The frequency converter in the air compressor 10 adjusts the motor speed, directly changing the compressor's discharge volume (the lower the speed, the smaller the discharge volume), achieving "stepless adjustment". The pressure sensor 242 in each branch pipe 24 provides real-time feedback on the discharge pressure within the branch pipe 24 and sends it to the main control module 30. The main control module 30 sends the value to the frequency converter, which compares the actual pressure with the set value and sends a signal to adjust the motor speed, changing the air intake volume and stabilizing the discharge pressure at the set value. This allows medical personnel to control the drying pressure according to different instruments.
[0028] The cabinet door 22 is also equipped with a display 225, which is connected to the main control module 30. When the user closes the cabinet door 22, he / she can view the real-time value monitored by the pressure sensor 242 on the display 225.
[0029] The specific usage process of this multi-channel timed pressure drying device is as follows: 1) Open the cabinet door 22 and turn on the opening and closing switch button 257 of the corresponding instrument clamp 25. The first clamp arm 252 and the second clamp arm 253 open. Place the instrument between the first clamp arm 252 and the second clamp arm 253. After releasing the button, the first clamp arm 252 and the second clamp arm 253 close under the action of the return spring 256, clamping the instrument; 2) Move the slide 281 corresponding to the hose clamp 27 so that the hose clamp 27 is in front of the instrument. Use the hose clamp 27 to clamp the corresponding blower hose 26; 3) ... According to the angle of the through hole on the instrument, rotate the rotating seat 284 on the cable 282 so that the nozzle of the blower hose 26 on the hose clamp 27 is aligned with the through hole on the instrument; 4) Close the cabinet door 22, use the timer 224 to set the drying time, start the main switch 221 and the corresponding branch pipe on / off switch 223, use the blower hose to blow dry the inside of the instrument, and the air curtain drying device to blow dry the surface of the instrument; and can adjust the air intake of the air compressor 10 by real-time feedback of the exhaust pressure in the branch pipe 24 based on the pressure sensor 242 in each branch pipe 24, thereby adjusting the blowing pressure.
