Description

Technical Field

[0001] The present invention relates to the field of medical equipment, in particular to a sterilization device and a sterilization process for a sodium bicarbonate injection bottle. Background Art

[0002] The existing sealed containers for liquid medicines have been changed from the original glass to liquid medicine bottles made of polypropylene, thereby achieving the functions of safe transportation and easy opening. However, a necessary disinfection procedure is essential. Therefore, the heat resistance temperature of liquid medicine bottles made of glass is much higher than that of liquid medicine bottles made of polypropylene. Therefore, the traditional disinfection method is not suitable for sodium bicarbonate injection liquid medicine bottles made of polypropylene.

[0003] The Chinese invention patent with publication number CN103028125B disclosed a high-temperature disinfection cabinet on August 19, 2015, comprising a cabinet body (1), a cabinet door, and a cabinet inner chamber (4); the cabinet door is connected to the cabinet body (1) via sliding guide rails provided at both ends of the cabinet door; a computer main control board (7) is also provided in the cabinet body (1); a heating pipe (8) is provided on the inner side of the rear portion of the cabinet inner chamber (4); the heating pipe (8) is connected to the computer main control board (7) via a first wire (9); a heating plate (10) is provided on the inner side of the cabinet door; the heating plate (10) is connected to the computer main control board (7) via a second wire (11); and a heat insulation layer (12) is provided between the heating plate (10) and the cabinet door. The high-temperature disinfection cabinet has a large high-temperature radiation area, a short heating cycle, and a good sterilization effect.

[0004] However, the above-mentioned disclosed solutions have the following shortcomings: the existing disinfection cabinets do not have a pressurizing function, which makes it convenient and effective to use for disinfecting glass medicine bottles. However, when disinfecting sodium bicarbonate injection bottles made of polypropylene material, a large amount of carbon dioxide will be released in the bottle during the heating and disinfection process, causing the bottle shape to expand, and then shrink rapidly when cooled, causing wrinkles in the bottle shape, resulting in an irregular bottle shape and reduced thickness. Summary of the Invention

[0005] The object of the present invention is to solve the above technical problems and provide a sterilization device and a sterilization process for sodium bicarbonate injection bottles.

[0006] In order to achieve the above objectives, the present invention adopts the following technical solutions:

[0007] The technical solution adopted by the present invention to solve its technical problem is: a sterilization device and sterilization process of a sodium bicarbonate injection bottle described in the present invention comprises a sterilization container, a container lid and an air pressure regulating unit; the left opening of the sterilization container is detachably and sealedly fixedly connected to the container lid; the container lid is connected and fixedly connected to a pressure gauge and a thermocouple; the interior of the sterilization container is sealed and fixedly connected to a first baffle; the sterilization container and the first baffle are fixedly connected to an insulation plate; the insulation plate is fixedly connected to an electric heating wire; the electric heating wire is fixedly connected to a partition plate at intervals; the first baffle, the partition plate and the insulation plate are provided with a connecting hole; the connecting hole is connected and fixedly connected to the air pressure regulating unit; when working, by opening the container lid, a large number of sodium bicarbonate injection bottles made of polypropylene are moved into the partition plate using a forklift or a pallet truck, and then the sterilization container is sealed through the container lid, at which time the electric heating wire is energized and heated in conjunction with the thermocouple to the energized state. The sterilization is carried out by heating to 121 degrees. At the same time, during heating, the air pressure regulating unit dynamically delivers air to the partition plate, so that the sodium bicarbonate injection bottle made of polypropylene is continuously subjected to 4.8 atmospheres of pressure and is continuously heated for 15 minutes. Then the electric heating wire is powered off for cooling. At this time, the air pressure regulating unit continues to deliver air to 4.9 atmospheres of pressure. After the thermocouple detects that the ambient temperature of the sodium bicarbonate injection bottle made of polypropylene reaches 45 degrees, the air pressure regulating unit discharges air, so that the ambient atmospheric pressure of the sodium bicarbonate injection bottle reaches 1 atmosphere. At this time, the container cover can be opened to take out the sterilized sodium bicarbonate injection bottle, and the surface of the sodium bicarbonate injection bottle is guaranteed to be wrinkle-free and the thickness is maintained, maintaining the designed strength and appearance, thereby solving the problem that the surface of the sodium bicarbonate injection bottle is wrinkled and the thickness is reduced when the existing normal pressure sterilization device is used to sterilize the sodium bicarbonate injection bottle.

[0008] Furthermore, the air pressure regulating unit includes an electronic valve and a second baffle; the electronic valve is connected and fixed on the connecting hole; the end of the electronic valve is connected and fixed with the second baffle; the second baffle is sealed and fixed in the sterilization container; the second baffle is fixedly connected to a support plate; the support plate has an opening and a threaded shaft rotatably inserted; the end of the threaded shaft is sleeved with a support seat; the end of the threaded shaft is inserted with a hexagonal prism; the hexagonal prism is fixedly connected to a motor through a coupling; the lower end of the motor is fixedly connected to a frame; the frame is fixedly connected to the support cover; a sealing baffle is threadedly sleeved on the threaded shaft; the outer surface of the sealing baffle is grooved and sleeved with a sealing strip; the sealing baffle is sealingly slidably inserted in the sterilization container; when working, a large number of sodium bicarbonate injection bottles are placed in the sterilization container through the motor, thermocouple and barometer external processor, the electric heating wire is energized and heated to one hundred and twenty degrees, and during the heating process, the motor rotates with The dynamic sealing baffle moves in the sterilization container, injecting air into the left side of the first baffle, thereby pressurizing the sterilization space of the sodium bicarbonate injection bottle to 4.8 atmospheres, maintaining the pressure and heating for fifteen minutes. During the pressure maintenance, the electronic valve is closed, so that the motor does not need to work, and then the electric heating wire is stopped for heating. At the same time, the sealing baffle continues to move to increase the sterilization space to 4.9 atmospheres until the temperature reaches 45 degrees. At this time, the electronic valve is opened, and the motor rotates in the opposite direction to drive the sealing baffle, so that the 4.9 atmospheres of pressure is reduced to one atmosphere. Then the electronic valve is closed, the container lid is opened, and a large number of sterilized sodium bicarbonate injection bottles can be taken out. In this way, the expansion and shrinkage of the bottle shape are effectively reduced, so that the shape of the sodium bicarbonate injection bottle remains intact, without wrinkles and reduced sealing strength, solving the problem that wrinkles and reduced sealing strength will occur when the existing normal pressure heating sterilization device is used to sterilize sodium bicarbonate injection bottles.

[0009] Furthermore, fasteners are threadedly inserted into the openings on the support cover corresponding to the sterilization container; a plurality of ventilation holes are provided on the support cover corresponding to the sealing baffle; when working, the inner and outer spaces of the sterilization container are connected through the ventilation holes, so that the reciprocating movement of the sealing baffle can drive the air in the sterilization container to move quickly, blowing the motor away to take away the heat, so that the motor always maintains low-temperature operation and ensures long-term service life.

[0010] Furthermore, the left opening of the sterilization container corresponds to the container cover fixed with a bevel block; the inner surface of the container cover is grooved and fixed with an insulation block; during operation, the insulation capacity of the container cover is enhanced by the insulation block, so that the heat loss rate of the sterilization container is reduced, making it more energy-saving and safer; the bevel block is used to obliquely connect the lower end of the sterilization container opening and the ground, making it convenient for a forklift to move up and down or a cart to slide up and down, making the transfer of a large number of sodium bicarbonate injection bottles more convenient and quick, solving the problem of inconvenient loading and unloading materials in existing large-scale sterilization equipment.

[0011] Furthermore, a plurality of duckbill buckles are fixedly connected between the container cover and the sterilization container; during operation, the container cover can be conveniently and quickly detachably fixedly connected to the sterilization container through the plurality of duckbill buckles, thereby making it more convenient and quick to input or output sodium bicarbonate injection bottles into or out of the sterilization container through a cart or a storage rack during use, so that a large number of sodium bicarbonate injection bottles can be sterilized at one time.

[0012] A sterilization process for sodium bicarbonate injection bottles, which is applicable to the sterilization device for the sodium bicarbonate injection bottles described above, comprises the following steps:

[0013] S1: First, open the container cover and move a large number of sodium bicarbonate injection bottles to the partition board using a pallet truck or forklift;

[0014] S2: Then, the electric heating wire, electronic valve, motor, and thermocouple are energized and connected to an external processing device. The electric heating wire and the thermocouple are used to raise the ambient temperature of the sodium bicarbonate injection bottle to 121 degrees and maintain it. At the same time, the motor drives the threaded shaft to rotate, changing the position of the sealing baffle and delivering air to the left side of the first baffle, thereby raising the ambient pressure of the sodium bicarbonate injection bottle to 4.8 atmospheres. The pressure is maintained for 15 minutes. During the pressure maintenance period, the electronic valve is closed and the motor is powered off.

[0015] S3: After 15 minutes, the electric heating wire 7 is powered off, and the sealing baffle 21 continues to move so that the ambient pressure of the sodium bicarbonate injection bottle is 4.9 atmospheres. The ambient temperature of the sodium bicarbonate injection bottle slowly decreases. When the thermocouple 26 detects 45 degrees, the sealing baffle 21 retreats, so that the ambient pressure of the sodium bicarbonate injection bottle returns to 1 atmosphere.

[0016] S4: At this time, close the electronic valve, open the container cover to take out the sterilized sodium bicarbonate injection bottle, then put in a new sodium bicarbonate injection bottle, and repeat the operation for sterilization.

[0017] The present invention provides a sterilization device and sterilization process for a sodium bicarbonate injection bottle, which has the following features:

[0018] Beneficial effects:

[0019] 1. The present invention opens the container lid, uses a forklift or a pallet truck to move a large number of sodium bicarbonate injection bottles made of polypropylene into the partition plate, and then seals the sterilization container with the container lid. At this time, the electric heating wire cooperates with the thermocouple to heat to 121 degrees for sterilization. At the same time, during heating, the air pressure regulating unit dynamically supplies air into the partition plate, so that the sodium bicarbonate injection bottles made of polypropylene are continuously subjected to 4.8 atmospheres of pressure and are continuously heated for 15 minutes. Then the electric heating wire is powered off for cooling. At this time, the air pressure regulating unit continues to supply air to 4.9 atmospheres of pressure. After the thermocouple detects that the ambient temperature of the sodium bicarbonate injection bottles made of polypropylene reaches 45 degrees, the air pressure regulating unit discharges air so that the ambient atmospheric pressure of the sodium bicarbonate injection bottles reaches 1 atmosphere. At this time, the container lid can be opened to take out the sterilized sodium bicarbonate injection bottles, and the surface of the sodium bicarbonate injection bottles is guaranteed to be wrinkle-free and the thickness is maintained, so as to maintain the designed strength and appearance, thereby solving the problem that the surface of the sodium bicarbonate injection bottles is wrinkled and the thickness is reduced when the conventional normal pressure sterilization device is used to sterilize the sodium bicarbonate injection bottles.

[0020] 2. The present invention uses a motor, a thermocouple, and a barometer external processor. After a large number of sodium bicarbonate injection bottles are placed in the sterilization container, the electric heating wire is energized and heated to 121 degrees. During the heating process, the motor rotates to drive the sealing baffle to move in the sterilization container, injecting air to the left side of the first baffle, thereby pressurizing the sterilization space of the sodium bicarbonate injection bottles to 4.8 atmospheres. The pressure is maintained and heated for 15 minutes. During the pressure maintenance, the electronic valve is closed, making the motor unnecessary to work, and then the electric heating wire is stopped. At the same time, the sealing baffle continues to move to increase the sterilization space to 4.9 Atmospheric pressure is increased until the temperature reaches 45 degrees. At this time, the electronic valve is opened, and the motor rotates in the opposite direction to drive the sealing baffle, so that the 4.9 atmospheric pressure is reduced to one atmospheric pressure. Then the electronic valve is closed, and the container cover is opened to take out a large number of sterilized sodium bicarbonate injection bottles. In this way, the expansion and shrinkage of the bottle shape are effectively reduced, so that the shape of the sodium bicarbonate injection bottle remains intact without wrinkles or reduced sealing strength, which solves the problem that wrinkles and reduced sealing strength will occur when the existing normal pressure heating sterilization device is used to sterilize sodium bicarbonate injection bottles.

During the pressure maintenance, the electronic valve 10 is closed, so that the motor 17 does not need to work, and then the electric heating wire 7 stops heating. At the same time, the sealing baffle 21 continues to move to increase the sterilization space to 4.9 atmospheres until the temperature reaches 45 degrees. At this time, the electronic valve 10 is opened, and the motor 17 rotates in the opposite direction to drive the sealing baffle 21, so that the 4.9 atmospheres of pressure is reduced to one atmosphere.

The electric heating wire 7 cooperates with the thermocouple 26 to raise the ambient temperature of the sodium bicarbonate injection bottle to 121 degrees and maintain it. At the same time, the motor 17 drives the threaded shaft 13 to rotate, changing the position of the sealing baffle 21 and delivering air to the left side of the first baffle 3, thereby raising the ambient pressure of the sodium bicarbonate injection bottle to 4.8 atmospheres.

At this time, the electric heating wire 7 cooperates with the thermocouple 26 to be energized and heated to 121 degrees for sterilization. At the same time, during heating, the air pressure regulating unit dynamically delivers air into the partition plate 8, so that the sodium bicarbonate injection bottles made of polypropylene are continuously subjected to 4.8 atmospheres of pressure and are continuously heated for 15 minutes. Then the electric heating wire 7 is powered off for cooling. At this time, the air pressure regulating unit continues to deliver air to 4.9 atmospheres of pressure until the thermocouple 26 detects that the sodium bicarbonate injection bottles made of polypropylene are After the ambient temperature reaches 45 degrees, the air pressure regulating unit discharges air, so that the ambient atmospheric pressure of the sodium bicarbonate injection bottle reaches one atmosphere. At this time, the container cover 2 can be opened to take out the sterilized sodium bicarbonate injection bottle, and the surface of the sodium bicarbonate injection bottle is guaranteed to be wrinkle-free and the thickness is maintained, and the designed strength and appearance are maintained, which solves the problem that the surface of the sodium bicarbonate injection bottle is wrinkled and the thickness is reduced when the existing normal pressure sterilization device is used to sterilize the sodium bicarbonate injection bottle; through the motor 17, the thermocouple 26 and the pressure gauge 5 external processor, after a large number of sodium bicarbonate injection bottles are placed in the sterilization container 1, the electric heating wire 7 is energized and heated to one hundred and twenty degrees, and during the heating process, the motor 1 7 rotates to drive the sealing baffle 21 to move in the sterilization container 1, and injects air into the left side of the first baffle 3, thereby pressurizing the sterilization space of the sodium bicarbonate injection bottle to 4.8 atmospheres, and heating at this pressure for 15 minutes. During the pressure maintenance, the electronic valve 10 is closed, so that the motor 17 does not need to work, and then the electric heating wire 7 is stopped for heating.

S3: After 15 minutes, the electric heating wire (7) is powered off, and the sealing baffle (21) continues to move so that the ambient pressure of the sodium bicarbonate injection bottle is 4.9 atmospheres. The ambient temperature of the sodium bicarbonate injection bottle slowly decreases. When the thermocouple (26) detects 45 degrees, the sealing baffle (21) retreats, so that the ambient pressure of the sodium bicarbonate injection bottle returns to 1 atmosphere. S4: At this time, close the electronic valve (10), open the container cover (2), take out the sterilized sodium bicarbonate injection bottle, and then put in a new sodium bicarbonate injection bottle, and repeat the operation for sterilization.
