Description

Technical Field

[0001] The utility model relates to the technical field of medical instrument disinfection, in particular to an instrument disinfection device. Background Art

[0002] The laboratory department is a bridge between clinical medicine and basic medicine, including branch disciplines such as clinical chemistry, clinical microbiology, clinical immunology, hematology, fluidology, and blood transfusion. It is mainly responsible for the testing of various human and animal specimens including those in wards, outpatient and emergency patients, various physical examinations, and scientific research. However, when sampling and testing specimens, it is usually necessary to disinfect the instruments to ensure that the specimens are not contaminated.

[0003] When using high-temperature steam sterilization, a batch of instruments are placed in the sterilization box at the same time. After cleaning, the used instruments need to wait until a certain amount of instruments have accumulated before they can be sterilized together. This creates an idle period while all instruments are being sterilized, and the sterilization efficiency needs to be improved. Therefore, we propose an instrument sterilization device. Utility Model Content

[0004] The purpose of the utility model is to provide an instrument disinfection device, which can place instruments to be disinfected in the compartments by arranging a plurality of compartments separated by spacers on the outer ring of a rotating roller.

[0006] By adopting the above technical solution, the instruments are placed in different compartments between the partition blocks and transferred into the disinfection box for disinfection. When the instruments need to be taken out for use and disinfection, their corresponding compartments can be rotated upwards to align with the opening, making it easier to take out the instruments without affecting the disinfection of other instruments.

[0007] Optionally, a rubber pad is fixedly attached to the inner surface of the inner cylinder at the end of the spacer, and the rubber pad is in contact with the outer surface of the end of the spacer.

[0008] By adopting the above technical solution, when taking out instruments from the top compartment and its opening, the rubber pad can maintain the sealing effect between the partition block and the inner cylinder to prevent steam leakage.

[0009] Optionally, an upper cover is placed above the opening, and a handle is fixed in the middle of the surface of the upper cover.

[0010] By adopting the above technical solution, the opening is shielded and sealed by the upper cover.

[0011] Optionally, a pressure relief valve is connected to the upper side of the disinfection box, and the pressure relief valve is connected to the interior of the disinfection box.

[0012] By adopting the above technical solution, when the heating pressure inside the disinfection box is too high, the pressure can be released through the pressure relief valve.

[0013] Optionally, a temperature sensor is installed at the bottom of the interior of the disinfection box, and a water level sensor is installed on the inner wall surface of the disinfection box above the side of the temperature sensor.

[0017] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0018] 1. The technical solution of the present application is to arrange multiple compartments separated by spacers on the outer ring of the roller, so that instruments to be sterilized can be placed in the compartments. Only one compartment can be rotated to align with the opening above to take out the instruments, while the other compartments continue to be connected to the interior of the disinfection box without affecting the disinfection work. There is no need to accumulate instruments for disinfection together, thereby improving the disinfection efficiency.

[0019] 2. The technical solution of this application fixes a heat-resistant rubber pad on the inner surface of the inner tube on the side of the partition block between the compartments, so that when the upper compartment is aligned with the opening, the partition block and the inner tube can be well sealed to reduce steam leakage.

When the pressure inside the disinfection box 1 is too high, the pressure relief valve 16 can be pushed open to exhaust the air to avoid excessive pressure. A drain pipe 15 is connected to the lower side of the disinfection box 1 and is connected to the inside. A screw cover 151 is connected to the drain pipe 15 by a screw connection. When it is necessary to drain the water inside the disinfection box 1, the screw cover 151 can be unscrewed to drain and clean the water from the drain pipe 15.

[0027] The inner cylinder 2 is fixed on the upper part of the interior of the disinfection box 1. An opening 21 is provided on the upper part of the inner cylinder 2 and is connected to the upper outside of the disinfection box 1. A roller 3 is longitudinally rotatably installed in the middle position inside the disinfection box 1, and the roller 3 is connected to the stepper motor 33 installed on the front end surface of the disinfection box 1. The stepper motor 33 can drive the roller 3 to rotate to the required angle.

[0028] A plurality of spacers 31 are evenly fixed on the outer ring of the rotating roller 3, whose ends touch the inner surface of the inner cylinder 2. In order to achieve a good sealing effect between the spacers 31 and the inner cylinder 2, rubber pads 311 are fixed to the inner surface of the inner cylinder 2 at the ends of the spacers 31. The rubber pads 311 touch the outer surfaces of the ends of the spacers 31. Compartments 32 for placing instruments are provided between the spacers 31. When the compartments 32 are rotated to the uppermost position, they are sealed and high-temperature steam will not leak out, so that instruments can be conveniently placed in or removed through the openings 21. Through holes 22 are evenly opened on the surface of the inner cylinder 2 except for the contact positions of the spacers 31. The compartments 32 rotated into the interior of the sterilization box 1 enter the high-temperature steam through the through holes 22.

There is no need to wait for a certain amount of instruments to accumulate before sterilizing them all at once. Instruments can be placed in different compartments 32 to achieve the purpose of continuous and consecutive sterilization, thereby achieving the purpose of improving the sterilization efficiency of medical instruments.

[0029] During the disinfection process or when the device is not in use, the opening 21 is covered with an upper cover 4 to seal it. A handle 41 is fixed in the middle of the surface of the upper cover 4 to facilitate the lifting and lowering of the upper cover 4 .

[0030] During use, the electric heater 11, the temperature sensor 12, the water level sensor 13 and the stepper motor 33 are all connected to the control device, the sealing block 141 is unscrewed to inject clean water into the disinfection box 1 through the water inlet 14, and the water level height is detected by the water level sensor 13, the electric heater 11 is started to heat the water inside the disinfection box 1 to boil and generate a large amount of steam, the upper cover 4 is removed and the instruments to be disinfected are placed into the compartment 32 between the partition blocks 31 through the opening 21, and then the stepper motor 33 drives the roller 3 to rotate clockwise, and then switches to align the side openings of other compartments 32 with the openings 21, and the instruments to be disinfected can be placed in other compartments 32, so that the other compartments 32 except those aligned with the openings 21 are rotated into the inside of the disinfection box 1 and passed through the passage. The hole 22 is connected to the interior of the disinfection box 1, so that high-temperature steam can enter the compartment 32 through the through hole 22 to disinfect the instruments placed therein. The upper cover 4 is covered during the disinfection process. When the instruments need to be taken out for use, the upper cover 4 is also removed first. The stepper motor 33 can be used to control the rotation of the roller 3 and other structures to rotate the compartment 32 where the corresponding instrument is placed to the top and align it with the opening 21, so that the instrument can be taken out from the opening 21 using tools. The other compartments 32 are not aligned with the opening 21 and can remain connected to the inside of the disinfection box 1, so that the disinfection work can continue. During operation, the water temperature is monitored by the temperature sensor 12, and the water level is monitored by the water level sensor 13, so that the heating temperature or water level height can be adjusted in time.
