Description

Technical Field

[0001] The present invention belongs to the technical field of disinfection and sterilization of medical dressings, and particularly relates to an automatic disinfection and sterilization device and method for medical dressings. Background Art

[0002] Medical dressings are a type of medical material used to cover sores, wounds or other damages, mainly including natural gauze, synthetic fiber dressings, polyfilm dressings, foamed polymer dressings, hydrocolloid dressings, alginate dressings, etc. Since medical dressings are in direct contact with the patient's wound, during the application of medical dressings, disinfection and sterilization treatment must be carried out to ensure the use safety and sterility of medical dressings.

[0003] Currently, the common disinfection and sterilization methods for medical dressings mainly include: high-temperature steam disinfection, ultraviolet negative ion disinfection, and disinfectant disinfection. Among them, high-pressure steam disinfection can not only kill ordinary bacteria, but also kill bacterial spores. Due to its advantages of fast disinfection and sterilization speed, no chemical drugs, and good sterilization effect, it is widely used.

[0004] In the prior art, a high-pressure steam sterilization device is usually used as a disinfection and sterilization device for medical dressings to perform disinfection and sterilization treatment on medical dressings. However, such a high-pressure steam sterilization device cannot be adaptively adjusted according to different medical dressings during use. At the same time, the steam of such a high-pressure steam sterilization device is mainly transported from bottom to top, and the uniformity of high-temperature steam transportation is poor, resulting in different disinfection and sterilization effects on medical dressings at different horizontal heights. In order to ensure the sterilization effect of medical dressings, it is necessary to extend the disinfection and sterilization cycle, making the applicability and sterilization efficiency of the high-pressure steam sterilization device poor.

[0005] The information disclosed in this background art section is only intended to enhance the overall understanding of the present invention and should not be regarded as an admission or any form of suggestion that this information constitutes prior art already known to those of ordinary skill in the art.

[0021] The automatic disinfection and sterilization method for medical dressings includes the following steps:

[0022] S1. When it is necessary to disinfect and sterilize medical dressings, the closed box cover is opened by rotating and adjusting the screw rod. Subsequently, the fixed column is taken out of the closed disinfection and sterilization cavity by pulling the handle.

[0023] S2. According to the actual situation of the medical dressings, the lifting lead screw is driven to rotate by controlling the rotation of the end head. Under the action of the internal and external threads, the plurality of threaded drive blocks can move along with the rotation of the lifting lead screw. The intervals between the plurality of supporting mesh trays are adjusted by controlling the movement of the plurality of threaded drive blocks, so that the intervals between the plurality of supporting mesh trays are adapted to the medical dressings.

[0024] S3. Then, the medical dressings to be disinfected and sterilized can be placed on the supporting mesh trays, and the medical dressings are separated by a plurality of partition plates. After the medical dressings are placed, the fixed column can be placed into the closed disinfection and sterilization cavity by pulling the handle. During the placement process, the fixed column is assembled and limited by the mutual engagement of the rotary fixed base and the fixed column.

Through the mutual cooperation of multiple groups of lower disinfection nozzles and side disinfection nozzles, high-temperature steam is evenly conveyed into the enclosed disinfection and sterilization cavity in a manner from bottom to top and from outside to inside. The medical dressings placed on the supporting wire mesh tray are disinfected and sterilized by the high-temperature steam.

[0027] S6. At the same time, the operation of the rotating motor can be controlled to drive the transmission gear to rotate. The rotating fixed base can drive the fixed column to rotate under the meshing action of the driving gear and the transmission gear. The supporting wire mesh tray is driven to rotate synchronously by the rotation of the fixed column, so that the medical dressings placed on the supporting wire mesh tray can be disinfected and sterilized at multiple angles.

[0028] S7. In addition, the high-temperature steam conveyed in the intake pipe can be sprayed out from multiple groups of inner nozzles from inside to outside along the cooperation of the auxiliary steam inlet pipe, the steam conduction groove and the exhaust steam connecting groove, so as to efficiently disinfect and sterilize the medical dressings placed on the supporting wire mesh tray.

High-temperature steam is conveyed from the outside to the inside of the closed disinfection and sterilization chamber through the multiple groups of side disinfection nozzles 202, thereby improving the efficiency of high-pressure steam disinfection of medical dressings.

[0054] As Figures 1 to 2 shown, a steam communication pipe 204 is connected between the multiple groups of side disinfection nozzles 202.

[0062] As Figures 4 to 5 shown, the adjustable dressing support mechanism 3 is snap-fitted and assembled in the closed disinfection and sterilization chamber. The adjustable dressing support mechanism 3 includes a fixed column 301. The multi-group support mesh trays 304 are assembled and limited by the fixed column 301, so as to facilitate the support of medical dressings.

[0063] As Figures 4 to 5 shown, a handle 306 is hinged above the fixed column 301. The fixed column 301 is disassembled and assembled conveniently by controlling the lifting of the handle 306.

[0064] As Figures 8 to 9 shown, a lifting lead screw 302 is rotatably connected inside the fixed column 301. The lifting lead screw 302 plays a role in locking and limiting and lifting control on the threaded drive block 303.

[0065] As Figures 8 to 9 shown, one end of the lifting lead screw 302 located outside the fixed column 301 is fixedly connected with an end head 307. The lifting lead screw 302 is driven and controlled by controlling the rotation of the end head 307.

The threaded drive blocks 303 are connected and limited to the lifting lead screw 302 and the support mesh trays 304, so as to facilitate the lifting control of the support mesh trays 304 by controlling the lifting of the threaded drive blocks 303.

[0067] Among them, a plurality of lifting guide chutes are drilled on the outside of the fixed column 301, and the lifting guide chutes are arranged in cooperation with the threaded drive blocks 303. The lifting guide chutes play a role in guiding the lifting of the threaded drive blocks 303, ensuring the lifting stability of the threaded drive blocks 303.

[0068] As Figures 8 to 9 shown, a support mesh tray 304 is fixedly connected to the outside of each of the plurality of threaded drive blocks 303. The medical dressings are supported and limited by the support mesh trays 304.

[0072] Among them, a driving cavity is drilled at the bottom of the disinfection inner shell 201. By drilling the driving cavity, an assembly and operation space is provided for the driving gear 402 and the transmission gear 403.

[0073] As Figures 1 to 3 shown in the figure, a driving gear 402 is fixedly connected to one side of the rotary fixed base 401 located in the driving cavity. The driving gear 402 plays a role in rotating and driving the rotary fixed base 401.

[0074] As Figures 1 to 3 shown in the figure, a transmission gear 403 is engaged with one side of the driving gear 402. The transmission gear 403 plays a role in transmitting the output shaft of the rotating motor 404.

[0075] As Figures 1 to 3 shown in the figure, a rotating motor 404 is fixedly assembled below the disinfection inner shell 201, and the output shaft of the rotating motor 404 is in transmission connection with the transmission gear 403. The rotating motor 404 plays a role in providing power. By controlling the operation of the rotating motor 404, the transmission gear 403 is rotationally driven, so as to facilitate the rotation control of the fixed column 301.

[0076] As Figures 1 to 3 shown in the figure, an auxiliary steam inlet pipe 405 is rotatably connected below the rotary fixed base 401, and one end of the auxiliary steam inlet pipe 405 away from the rotary fixed base 401 is communicated with the air inlet pipe 207. High-temperature steam is conveyed into the steam conduction groove through the auxiliary steam inlet pipe 405.

[0077] It should be noted that a steam conduction groove is drilled inside the fixed column 301, and multiple groups of evenly distributed fixed conduction rings 406 are sleeved on the outer side of the fixed column 301.

[0078] As Figures 4 to 5 shown, multiple groups of fixed conduction rings 406 are evenly arranged between multiple groups of supporting mesh trays 304, and the fixed conduction rings 406 play a role in assembling and fixing the inner nozzles 407.

[0079] Among them, exhaust steam communication grooves are drilled in multiple groups of fixed conduction rings 406, and the steam communication grooves are connected to the exhaust steam conduction grooves. The high-temperature steam conveyed by the auxiliary steam inlet pipe 405 is conveyed through the mutual cooperation of the steam communication grooves and the exhaust conduction grooves.

[0080] As Figures 4 to 5 shown, multiple groups of inner nozzles 407 are fixedly assembled on the outer sides of multiple groups of fixed conduction rings 406, and multiple groups of inner nozzles 407 are all connected to the exhaust steam communication grooves. The high-temperature steam is discharged from the inside to the outside of the closed disinfection and sterilization cavity by means of discharging the high-temperature steam through multiple groups of inner nozzles 407, improving the uniformity of conveying the high-temperature steam in the closed disinfection and sterilization cavity.

[0081] As Figures 1 to 10 shown, the automatic disinfection and sterilization method for medical dressings includes the following steps: When it is necessary to disinfect and sterilize medical dressings, the closed box cover 101 is opened by rotating the adjusting screw 103. Subsequently, the fixed column 301 is taken out of the closed disinfection and sterilization cavity by pulling the handle 306. According to the actual situation of the medical dressings, the lifting lead screw 302 is driven to rotate by controlling the rotation of the control end 307. Multiple groups of threaded drive blocks 303 can move along with the rotation of the lifting lead screw 302 under the action of the internal and external threads. The intervals between multiple groups of supporting mesh trays 304 are adjusted by controlling the movement of multiple groups of threaded drive blocks 303, so that the intervals between multiple groups of supporting mesh trays 304 are adapted to the medical dressings.

[0082] Then, the medical dressings to be disinfected and sterilized can be placed on the supporting mesh trays 304, and the medical dressings are separated by multiple partition plates 305. After the medical dressings are placed, the fixed column 301 can be placed into the closed disinfection and sterilization cavity by pulling the handle 306. During the placement process, the fixed column 301 is assembled and limited by the mutual engagement of the rotating fixed base 401 and the fixed column 301. After the fixed column 301 is placed, the closed box cover 101 can be buckled above the disinfection and sterilization box 1 by rotating the adjusting screw 103 in the reverse direction;

[0083] Subsequently, the air in the closed disinfection and sterilization chamber can be extracted by controlling the operation of the vacuum pump 209, so that the closed disinfection and sterilization chamber is in a vacuum state. Moreover, a steam generator can be externally connected through the conduction valve 208, and high-temperature steam can be transported into the closed disinfection and sterilization chamber by controlling the opening of the conduction valve 208. The temperature and pressure parameters in the closed disinfection and sterilization chamber can be monitored according to the temperature indicator and the pressure indicator.

[0084] The high-temperature steam transported through the air inlet pipe 207 can be transported into the closed disinfection and sterilization chamber from bottom to top along multiple lower disinfection nozzles 203 under the action of the lower delivery pipe 205 and the conduction pipe 206. At the same time, the high-temperature steam in the air inlet pipe 207 can be transported into the closed disinfection and sterilization chamber through multiple side disinfection nozzles 202 under the action of the steam connection pipe 204. Through the mutual cooperation of multiple lower disinfection nozzles 203 and side disinfection nozzles 202, high-temperature steam is evenly transported into the closed disinfection and sterilization chamber in a manner from bottom to top and from outside to inside, and the medical dressings placed on the supporting mesh tray 304 are disinfected and sterilized by the high-temperature steam.

[0085] Meanwhile, the operation of the rotating motor 404 can be controlled to drive the transmission gear 403 to rotate.
