Abstract
Description
Technical Field

[0002] Surgical gauze dressings are a common infusion, nursing and protective device, which can be divided into many types according to different needs and usage scenarios. Common types include sterile gauze dressings, sterilized gauze dressings, anti-stick gauze dressings, etc. Among them, antibacterial gauze dressings are suitable for surgery and wound dressings, which can effectively prevent infection.
[0003] Absorbent cotton gauze is the main raw material for surgical antibacterial cotton gauze dressings. Its main component is degreased pure cotton fiber, which is specially treated to form a fiber mesh structure, making it have better water absorption and adsorption. At present, there are two main types of absorbent cotton gauze used for surgical antibacterial cotton gauze dressings, one is sterile and drug-free type, and the other is drug-impregnated type. The sterile and drug-free type is to directly cut and shape the sterilized absorbent cotton gauze blanks, which can be directly applied when used. The drug-impregnated type is to soak the absorbent cotton gauze blanks in a medicine tank during the production process so that the cotton yarn contains antibacterial drug components, and then dry it. There is still room for improvement in the actual production process. For example, the drug-impregnating process itself is not complicated, but it takes a long time, and as the cotton yarn is continuously immersed in the medicine tank, the concentration of antibacterial drugs in the medicine tank will change, resulting in different antibacterial abilities of cotton yarns in the same batch. The soaked cotton yarn has an increased dimension in drying time and drying difficulty, and does not have the function of uniform drug administration and maintaining stable concentration.

[0027] Embodiment 3: A scale window 29 is provided on one side of the front end of the antibacterial liquid storage tank 2, a drug adding port 30 is provided on one side of the top end of the antibacterial liquid storage tank 2, a driving motor 31 is installed on the other side of the top end of the antibacterial liquid storage tank 2, a rotating shaft 32 is vertically movably connected to one side of the top end of the inner part of the antibacterial liquid storage tank 2, a stirring blade 33 is fixedly connected to the bottom end of the rotating shaft 32, the top end of the rotating shaft 32 is connected to the output end of the driving motor 31, and the bottom end of the stirring blade 33 is higher than the bottom end of the antibacterial liquid storage tank 2, which can prevent the precipitation of the drug solution and maintain its concentration stability; Specifically, Figure 1 and Figure 2As shown, the driving motor 31 drives the rotating shaft 32 to rotate continuously, and the stirring blades 33 at the bottom of the rotating shaft 32 continuously stir the antibacterial liquid in the antibacterial liquid storage tank 2 to prevent it from settling in a static state.
[0028] The steps for using this device are as follows: P1: Place the rolled absorbent cotton gauze blank on the blank rack 14, pull one end of it through the spray chamber 6 and the microwave drying chamber 18 in sequence, and reel it in at the end by the reeling device, and store the antibacterial liquid for spraying in the antibacterial liquid storage tank 2.
[0029] P2: As the winding device is wound, the absorbent cotton gauze blank can travel at a constant speed in the spray chamber 6 and the microwave drying chamber 18. The two sets of guide rollers 17 on the fixed frame 16 can limit the height and position of the cotton yarn to keep its tension and position stable.
[0030] P3: When the cotton yarn passes through the spray chamber 6, the metering pump 4 draws out the antibacterial liquid through the liquid outlet pipe 3, and pumps it to the first dispensing pipe 7 and the second dispensing pipe 8 through the liquid delivery pipe 5. The nozzles 9 on one side of the first dispensing pipe 7 and the second dispensing pipe 8 spray fine drugs to the lower coating roller 11 and the upper coating roller 10 respectively.

The absorbent cotton gauze blank that has been dried with the addition of medicine can enter the subsequent cutting and packaging.
[0033] Working principle: When the present invention is in use, first, the rolled absorbent cotton gauze blank is placed on the blank rack 14, and one end of the blank is pulled through the spray chamber 6 and the microwave drying chamber 18 in sequence, and is rolled up at the end by a winding device. Under the traction of the winding device, when the cotton yarn passes through the spray chamber 6, the metering pump 4 extracts the antibacterial liquid through the liquid outlet pipe 3, and pumps it to the first liquid dispensing pipe 7 and the second liquid dispensing pipe 8 through the liquid delivery pipe 5. The nozzles 9 on one side of the first liquid dispensing pipe 7 and the second liquid dispensing pipe 8 spray fine drugs to the lower coating roller 11 and the upper coating roller 10 respectively. When the absorbent cotton gauze blank passes between the lower coating roller 11 and the upper coating roller 10, its upper and lower surfaces can be evenly coated, and due to the pumping, the concentration of the drug solution can be kept consistent. The antibacterial liquid is added into the antibacterial liquid storage tank 2 through the dosing port 30, and the remaining amount of the liquid can be seen through the scale window 29. During the dosing process, the driving motor 31 drives the rotating shaft 32 to continuously rotate, and the stirring blade 33 at the bottom of the rotating shaft 32 continuously stirs the antibacterial liquid in the antibacterial liquid storage tank 2 to prevent it from settling in a static state. The coated absorbent cotton gauze blank enters the microwave drying chamber 18 under the traction of the winding device, and the microwave generated by the microwave control host 28 is guided by the waveguide 19 to perform microwave drying on the coated absorbent cotton gauze blank in the microwave drying chamber 18. The exhaust fan 21 in the fan housing 20 operates synchronously to suck the water vapor inside the microwave drying chamber 18 upward, and collects it to the collecting pipe 27 through the wind collecting hood 22 and the air guide tube 23 and discharges it outward. When the exhaust fan 21 is working, the air flow goes from bottom to top, and the wind force becomes larger after being collected by the wind collecting hood 22, so that the non-return cover plate 26 is lifted up, and the upper and lower air flows are unobstructed. When the exhaust fan 21 stops working, the non-return cover plate 26 is reset under the action of gravity, covers the annular plate 24 and closes the ventilation slot 25, the air flow in the air guide tube 23 is cut off, and the external air flow cannot flow back into the microwave drying chamber 18, which can effectively prevent pollution.

10. The method for producing absorbent cotton gauze for surgical antibacterial cotton gauze dressing according to claim 1, characterized in that: The steps for using this device are as follows: P1: placing a rolled absorbent cotton gauze blank on a blank rack (14), pulling one end of the rolled absorbent cotton gauze blank through a spray chamber (6) and a microwave drying chamber (18) in sequence, and rolling it up at the end by a rolling device, and storing the antibacterial liquid for spraying in an antibacterial liquid storage tank (2); P2: As the reeling device is reeled in, the absorbent cotton gauze blank can travel at a uniform speed in the spray chamber (6) and the microwave drying chamber (18). The two sets of guide rollers (17) on the fixed frame (16) can limit the height and position of the cotton yarn to keep its tension and position stable; P3: When the cotton yarn passes through the spray chamber (6), the metering pump (4) extracts the antibacterial liquid through the liquid outlet pipe (3) and pumps it to the first liquid dispensing pipe (7) and the second liquid dispensing pipe (8) through the liquid delivery pipe (5). The nozzles (9) on one side of the first liquid dispensing pipe (7) and the second liquid dispensing pipe (8) spray fine drugs to the lower coating roller (11) and the upper coating roller (10) respectively. When the absorbent cotton gauze blank passes between the lower coating roller (11) and the upper coating roller (10), the upper and lower surfaces thereof can be evenly coated. P4: The coated absorbent cotton gauze blank enters the microwave drying chamber (18) under the traction of the winding device, and the microwaves generated by the microwave control host (28) are guided by the waveguide (19) to perform microwave drying on the coated absorbent cotton gauze blank in the microwave drying chamber (18), so that the moisture content thereof is rapidly reduced; P5: During the drying process, the exhaust fan (21) in the fan housing (20) operates synchronously to draw the water vapor inside the microwave drying chamber (18) upward, collect it through the wind collecting hood (22) and the air guide tube (23) to the collecting pipe (27) and discharge it to the outside. The absorbent cotton gauze blank that has been dried with the addition of chemicals can then enter the subsequent slitting and packaging.
