Description

Technical Field

[0001] The invention relates to the technical field of hemostatic sponge disinfection, in particular to a disinfection device and a disinfection method for producing chitosan hemostatic sponge. Background Art

[0002] Chitosan hemostatic sponge is a loose and porous sheet in off-white or light yellow-brown color, similar to a sponge. This product has solubility and gelling properties. When in contact with the wound, it can absorb the exudate from the wound and accelerate hemostasis. The chitosan hemostatic sponge is a sponge-like product with water absorption and expansion properties. It can quickly absorb water in the blood to stop bleeding. The polycations of chitosan combine with the anions on the surface of the red blood cell membrane to cause red blood cell aggregation, while activating platelet aggregation and activating thrombin, thereby achieving the purpose of rapid hemostasis. It is soluble and forms a uniform chitosan gel layer on the bleeding wound, which plays a role in protecting the wound and stopping bleeding.

[0003] During the production process, chitosan hemostatic sponge needs to go through gel reaction, gel casting, freeze drying, slitting, disinfection and packaging. The slitting machine cuts the chitosan hemostatic sponge into appropriate sizes and then disinfects it, which requires the use of a disinfection device for the production of chitosan hemostatic sponge.

[0004] Most of the existing chitosan hemostatic sponge production disinfection devices generally use a flipping mechanism and multiple ultraviolet lamps to transport and flip the chitosan hemostatic sponge, so that the multiple ultraviolet lamps can fully disinfect the chitosan hemostatic sponge, or use ethylene oxide to sterilize the chitosan hemostatic sponge.

[0005] However, the above two methods may lead to incomplete disinfection of the chitosan hemostatic sponge, and ethylene oxide may remain on the chitosan hemostatic sponge, resulting in the risk of viral residues in the chitosan hemostatic sponge, making it impossible for the chitosan hemostatic sponge to meet the sterility requirements after production, thereby affecting the quality of the finished chitosan hemostatic sponge.

[0017] A method for disinfecting a disinfection device for producing a chitosan hemostatic sponge, which is applied to the above-mentioned disinfection device for producing a chitosan hemostatic sponge, comprises the following specific steps:

[0018] S1: The carrier plate is in an initial state outside the disinfection housing. The chitosan hemostatic sponge is clamped and fixed to the inside of the placement slot based on the clamping filter. The servo motor and the lead screw cooperate with each other, so that the carrier plate drives the installed chitosan hemostatic sponge into the interior of the disinfection housing, and the protective door is closed.

[0019] S2: Based on the pulse power supply, the voltage is transmitted to the electrode array through the wire, and the gas inside the gas collecting tank is transported to the inside of the plasma generating box. The strong electric field formed by the voltage of the electrode array ionizes the mixed gas, so that a low-temperature plasma cloud is generated inside the plasma generating box;

[0020] S3: Open the solenoid valve to allow the plasma cloud to enter the spiral tube. The spiral tube extends the transport path of the plasma cloud, prolongs the collision time between high-energy particles and carrier gas molecules, and reduces the damage ability of high-energy particles. At the same time, the short-wave UV in the gas is absorbed by the carrier gas molecules, reducing the intensity of the short-wave UV.

[0021] S4: The processed plasma enters the interior of the processing box, and is dispersed into the gas dispersion plate based on the through holes on the guide plate, so that the plasma is evenly sprayed into the installation cylinder and the placement groove through the guide pipe. At the same time, the air pump is started to extract the plasma through the exhaust pipe and the hollow tube, accelerating the plasma to pass through the chitosan hemostatic sponge;

[0022] S5: Start the driving motor so that the rotating disk drives the mounting cylinder to rotate, and drives the chitosan hemostatic sponge to rotate inside the disinfection shell, so that the plasma completes the simultaneous disinfection and sterilization of multiple chitosan hemostatic sponges based on the rotation of the mounting cylinder to obtain the final sterile chitosan hemostatic sponge.

[0023] Beneficial effects

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] Based on the mutual cooperation of structures such as the plasma disinfection mechanism and the diversion mechanism, the chitosan hemostatic sponge is cut and clamped inside the placement groove, and the electrode array is energized based on the pulse power supply to increase the voltage of the electrode array, thereby providing kinetic energy for the gas inside the plasma generating box, causing the gas to be ionized and obtaining a low-temperature plasma cloud. In addition, by setting the spiral tube, the gas transmission distance is increased, the collision time between high-energy particles and carrier gas molecules is prolonged, and the energy attenuation effect is enhanced. At the same time, when the short-wave UV is passing through the gas medium, it is absorbed or scattered by the carrier gas molecules, resulting in a significant attenuation of the intensity. Therefore, when the low-temperature plasma cloud disinfects the chitosan hemostatic sponge, the high-energy particles and short-wave UV are attenuated, reducing the damage of the high-energy particles and short-wave UV to the chitosan hemostatic sponge, thereby improving not only the disinfection effect of the chitosan hemostatic sponge but also the production quality of the chitosan hemostatic sponge.

[0026] The chitosan hemostatic sponge is disinfected by low-temperature plasma, which not only disinfects the chitosan hemostatic sponge more thoroughly, but also avoids the impact of high temperature on the chitosan hemostatic sponge. At the same time, it also avoids the risk of virus residue in the chitosan hemostatic sponge, so that the chitosan hemostatic sponge can meet the sterility requirements after production, thereby improving the production quality of the chitosan hemostatic sponge.

[0027] Based on the arrangement of the drive clamping mechanism and other structures, when the chitosan hemostatic sponge is disinfected and sterilized based on low-temperature plasma, the carrying plate drives the mounting cylinder and the chitosan hemostatic sponge to rotate inside the disinfection shell, thereby improving the disinfection effect of the chitosan hemostatic sponge on the plasma, and at the same time starting the water pump so that the exhaust pipe and the hollow tube exhaust air on one side of the chitosan hemostatic sponge, thereby accelerating the speed at which the plasma passes through the chitosan hemostatic sponge, thereby improving the disinfection efficiency of the chitosan hemostatic sponge on the plasma;

[0028] Based on the settings of the guide mechanism and the protection mechanism, after the plasma cloud attenuates through the spiral tube, the solenoid valve is started to allow it to enter the interior of the processing box. The high-energy particles and short-wave UV are monitored by the high-energy particle detector and the UV sensor to avoid the plasma still being sprayed into the disinfection shell through the guide tube when there are too many high-energy particles and short-wave UV. The guide plate and the gas dispersion plate cooperate with each other to guide and evenly disperse the plasma, so that the plasma is more uniform when disinfecting the chitosan hemostatic sponge.

The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise indicated.

[0045] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0046] In addition, numerous specific details are provided in the following specific examples to better illustrate the present application. Those skilled in the art will appreciate that the present application can be practiced without certain specific details. In some instances, methods, means, and components well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present application.

[0047] The present invention provides a disinfection device for producing chitosan hemostatic sponge, referring to Figures 1-9 , three embodiments are provided:

[0048] Example 1:

[0049] The chitosan hemostatic sponge production disinfection device comprises a disinfection shell 1, a driving clamping mechanism 2 is installed inside the disinfection shell 1, a plasma disinfection mechanism 3 is installed on one side of the disinfection shell 1, and a flow guide mechanism 4 is installed on one side of the plasma disinfection mechanism 3;

[0050] The disinfection housing 1 includes a disinfection housing 101, a protective door 102 with an observation window on the surface is hingedly connected to one side of the disinfection housing 101, a pulse power supply 307 is fixedly connected to the upper surface of the disinfection housing 101, and a support plate 103 fixedly connected to the plasma generating box 301 is fixedly connected to one side of the disinfection housing 101;

[0051] Among them, the protective door 102 is used to seal the disinfection housing 101;

[0052] The support plate 103 is used to support the plasma generating box 301, so that the plasma generating box 301 is more stable when in use;

[0053] The plasma disinfection mechanism 3 includes a plasma generating box 301 provided on one side of the disinfection housing 1. The two inner walls of the plasma generating box 301 are fixedly connected to the electrode array 302. A spiral tube 303 is fixedly connected to one side of the plasma generating box 301. One end of the spiral tube 303 is fixedly connected to the air inlet pipe 304. The surface of the air inlet pipe 304 is fixedly connected to the solenoid valve 305.

[0054] Among them, the plasma generating box 301 provides a space for ionization of the gas;

[0055] Among them, the electrode array 302 is used to ionize the gas;

[0056] The spiral tube 303 is used to increase the gas transmission distance, prolong the collision time between high-energy particles and carrier gas molecules, and enhance the energy attenuation effect. At the same time, when the short-wave UV passes through the gas medium, it is absorbed or scattered by the carrier gas molecules, resulting in a significant attenuation of the intensity.

[0057] Among them, the air inlet pipe 304 is used to transport plasma;

[0058] Among them, the solenoid valve 305 is used to control the intake pipe 304;

[0059] The upper surface of the plasma generator box 301 is fixedly connected to a gas collecting tank 306 containing nitrogen, oxygen, and argon respectively in a path array. The surfaces of several electrode arrays 302 are connected to a pulse power supply 307 via wires. A sealing cover 308 is hingedly connected to one side of the plasma generator box 301.

[0060] Among them, the gas collecting tank 306 is used to store multiple gases separately;

[0061] Wherein, the pulse power supply 307 is used to provide energy to the electrode array 302;

[0062] The sealing cover 308 is used to seal the plasma generating box 301;

[0063] Specifically, nitrogen, oxygen and argon in the gas collecting tank 306 are injected into the plasma generating box 301, and the electrode array 302 is energized based on the pulse power supply 307, so that the electrode array 302 generates voltage, and the voltage provides kinetic energy to the gas, so that the gas is ionized inside the plasma generating box 301 to obtain a plasma cloud, and the plasma cloud is allowed to enter the spiral tube 303, thereby extending the collision time between high-energy particles and carrier gas molecules and absorbing short-wave UV. When the low-temperature plasma cloud disinfects the chitosan hemostatic sponge, high-energy particles and short-wave UV are attenuated, reducing the damage of high-energy particles and short-wave UV to the chitosan hemostatic sponge, thereby improving not only the disinfection effect of the chitosan hemostatic sponge, but also the production quality of the chitosan hemostatic sponge.

[0064] Example 2, based on Example 1, further comprises a flow guide mechanism 4 comprising a process box 401 fixedly connected to one end of the air inlet pipe 304, a flow guide plate 402 having a rectangular array of through holes formed on its surface fixedly connected to an inner wall of the process box 401, a gas dispersion plate 403 connected to the surface of the process box 401 via the through holes, a flow guide pipe 404 fixedly connected to the surface of the gas dispersion plate 403 in a rectangular array, and a high-energy particle detector 405 and a UV sensor 406 fixedly connected to both sides of the interior of the process box 401, respectively;

[0065] The processing box 401 is used to store the processed plasma;

[0066] The guide plate 402 guides and disperses the plasma based on the arrangement of the through holes;

[0067] The gas dispersion plate 403 evenly sprays the plasma into the interior of the disinfection housing 101 through the flow guide tube 404;

[0068] The high-energy particle detector 405 and the UV sensor 406 are used to monitor the high-energy particles and UV in the plasma. When the energy of the particles in the plasma is too high or the intensity of the short-wave UV is too high, the solenoid valve 305 is controlled to cut off the transmission channel of the plasma to prevent the high-energy particles and short-wave UV from impacting the chitosan hemostatic sponge and causing damage to it.

[0069] Specifically, the solenoid valve 305 is activated to allow the attenuated plasma to enter the interior of the processing box 401. The plasma passes through the guide plate 402 through the through hole and enters the gas dispersion plate 403. The plasma is evenly sprayed onto the mounting cylinder 204 through the guide pipe 404, guiding and evenly dispersing the plasma, so that the plasma is more uniform when disinfecting the chitosan hemostatic sponge.

[0070] The disinfection housing 1 also includes a curved plate 104 fixedly connected to the lower surface of the support plate 103. A vacuum pump 105 whose input end is connected to the disinfection housing 101 is fixedly connected to the interior of the curved plate 104. The processing box 401 is fixedly connected to a side wall of the disinfection housing 101. The air inlet pipe 304 passes through one side of the disinfection housing 101 and is fixedly connected and connected to the processing box 401. The guide pipe 404 is arranged inside the disinfection housing 101.

[0071] The arc-shaped plate 104 is used to support the support plate 103 and fix the vacuum pump 105;

[0072] The vacuum pump 105 is used to exhaust the air inside the sterilization housing 101, so that the interior of the sterilization housing 101 becomes a vacuum state;

[0073] Specifically, after the chitosan hemostatic sponge enters the sterilization housing 101 and the protective door 102 is closed, the vacuum pump 105 is started to extract the air inside the sterilization housing 101, so that a vacuum is formed inside the sterilization housing 101, thereby reducing the subsequent temperature change inside the sterilization housing 101;

[0074] The protection mechanism 5 includes two sliding grooves 501 formed on the surface of the carrier plate 201. Curved protection plates 502 corresponding to the mounting cylinder 204 are slidably connected to both sides of the two sliding grooves 501. A driving source is fixedly connected to the interior of one of the sliding grooves 501 and is threadedly connected to the curved protection plate 502 via a threaded rod.

[0075] Among them, the sliding groove 501 is used for the movement of the arc-shaped protective plate 502;

[0076] The driving source and the threaded rod are used to drive the two arc-shaped protection plates 502 away from or towards each other;

[0077] The arc-shaped protective plate 502 is used to protect the installation cylinder 204 and guide the airflow during the rotation of the installation cylinder 204;

[0078] Specifically, during the plasma disinfection process of the chitosan hemostatic sponge, the chitosan hemostatic sponge rotates based on the mounting tube 204, so that a cyclone is generated inside the disinfection shell 101, thereby driving the plasma to rotate. Based on the setting of the arc-shaped protective plate 502, the plasma is guided so that the plasma always remains around the mounting tube 204.

[0079] Embodiment 3: Based on Embodiment 1 and Embodiment 2, further, the driving clamping mechanism 2 includes a carrying plate 201 slidably connected to the interior of the disinfection shell 101, a driving motor 202 is fixedly connected to the interior of the carrying plate 201, an output end of the driving motor 202 is fixedly connected to a rotating disk 203 rotatably connected to the carrying plate 201, and an upper surface of the rotating disk 203 is fixedly connected to a mounting cylinder 204;

[0080] Among them, the bearing plate 201 is used to support the mounting cylinder 204;

[0081] The driving motor 202 is used to drive the rotating disk 203 and the mounting cylinder 204 to rotate;

[0082] The driving clamping mechanism 2 also includes placement grooves 205 arranged in an annular array on the surface of the mounting cylinder 204 and corresponding to the existing chitosan hemostatic sponge. Two corresponding clamping filters 206 are installed on the inner top wall of the placement groove 205, one of which is fixedly connected to the placement groove 205, and the other is slidably connected to the placement groove 205. Elastic members 207 are fixedly connected to the tops of the opposite sides of the two clamping filters 206 in a path array. A hollow tube 208 is fixedly connected to the inner top wall of the mounting cylinder 204.

[0083] Among them, the placement groove 205 is used to place the chitosan hemostatic sponge;

[0084] Among them, the clamping filter 206 and the elastic member 207 are used to clamp the chitosan hemostatic sponge. Based on the setting of the clamping filter 206, the plasma can pass through the clamping filter 206 and enter the chitosan hemostatic sponge in contact with the clamping filter 206, avoiding dead corners in the disinfection of the chitosan hemostatic sponge;

[0085] The hollow tube 208 is used to transport the gas inside the mounting cylinder 204;

[0086] The driving and clamping mechanism 2 further includes an annular array of air extraction pipes 209 fixedly connected to the surface of the hollow tube 208. The air extraction pipes 209 correspond to the placement grooves 205 and are connected to the hollow tube 208. One end of the hollow tube 208 is fixedly connected to an air pump 210 fixedly connected to the rotating disk 203. A protective mechanism 5 is provided on the surface of the supporting plate 201.

[0087] The air extraction tube 209 and the air pump 210 are used to extract the gas from one side of the chitosan hemostatic sponge;

[0088] The driving clamping mechanism 2 also includes a servo motor 212 fixedly connected to the inside of the disinfection shell 101. The output end of the servo motor 212 is fixedly connected to a screw rod 211 that is threadedly connected to the supporting plate 201 and rotatably connected to the disinfection shell 101 through a bearing seat. A guide rod fixedly connected to the disinfection shell 101 is slidably inserted on one side of the lower surface of the supporting plate 201.

[0089] The servo motor 212 and the screw rod 211 are used to drive the carrier plate 201 to move, thereby driving the installation cylinder 204 to move;

[0090] Specifically, the supporting plate 201 is in the initial state outside the disinfection shell 101. The corresponding clamping filter 206 is pulled to extend the elastic member 207, and the chitosan hemostatic sponge is placed inside the placement groove 205 and on opposite sides of the two clamping filters 206. Based on the elastic force of the elastic member 207, the two clamping filters 206 clamp the chitosan hemostatic sponge so that it is fixedly connected to the inside of the placement groove 205. The servo motor 212 is started so that its output end drives the screw 211 to rotate, so that the supporting plate 201 drives the installed chitosan hemostatic sponge into the interior of the disinfection shell 101, and the protective door 102 is closed to seal the disinfection shell 101.

[0091] A method for disinfecting a disinfection device for producing a chitosan hemostatic sponge, which is applied to the disinfection device for producing the chitosan hemostatic sponge, comprises the following specific steps:

[0092] S1: The carrier plate 201 is initially positioned outside the disinfection housing 101. The chitosan hemostatic sponge is clamped and fixedly connected to the interior of the placement slot 205 using the clamping filter 206. The servo motor 212 and the screw 211 cooperate with each other, allowing the carrier plate 201 to drive the installed chitosan hemostatic sponge into the interior of the disinfection housing 101, and the protective door 102 is closed.

[0093] S2: The pulse power supply 307 transmits voltage to the electrode array 302 through the wire, and at the same time, the gas in the gas collecting tank 306 is transported to the interior of the plasma generating box 301. The strong electric field formed by the voltage of the electrode array 302 ionizes the mixed gas, so that a low-temperature plasma cloud is generated in the plasma generating box 301.

[0094] S3: Open the solenoid valve 305 to allow the plasma cloud to enter the spiral tube 303. The spiral tube 303 extends the transport path of the plasma cloud, prolongs the collision time between high-energy particles and carrier gas molecules, and reduces the damage ability of high-energy particles. At the same time, the short-wave UV in the gas is absorbed by the carrier gas molecules, reducing the intensity of the short-wave UV.

[0095] S4: The processed plasma enters the interior of the processing box 401. The plasma is dispersed into the gas dispersion plate 403 based on the through holes on the guide plate 402, so that the plasma is evenly sprayed into the installation cylinder 204 and the placement groove 205 through the guide tube 404. At the same time, the air pump 210 is started to extract the plasma through the exhaust pipe 209 and the hollow tube 208, accelerating the plasma to pass through the chitosan hemostatic sponge.

[0096] S5: Start the driving motor 202 so that the rotating disk 203 drives the mounting cylinder 204 to rotate, and drives the chitosan hemostatic sponge to rotate inside the disinfection shell 101, so that the plasma completes the synchronous disinfection and sterilization of multiple chitosan hemostatic sponges based on the rotation of the mounting cylinder 204, and obtains the final sterile chitosan hemostatic sponge.
