Description

Technical Field

[0001] The present invention relates to the technical field of medical device disinfection and sterilization devices, and particularly to a disinfection and sterilization device for medical care instruments. Background Art

[0002] The disinfection and sterilization of medical care instruments is an important measure to ensure patient safety, maintain medical environmental hygiene, reduce the risk of infection, and meet regulatory requirements. Through scientific and reasonable disinfection and sterilization processes and technical means, the quality and safety of medical services can be effectively improved.

[0003] Common disinfection and sterilization devices for medical care instruments include autoclaves, dry heat sterilizers, ethylene oxide sterilizers, hydrogen peroxide plasma sterilizers, and cassette sterilizers, etc. Among them, the cassette sterilizer is a device with a cartridge design, usually used for rapid sterilization of small and heat-sensitive medical care instruments. It generally consists of a main body and a sterilization cassette, and has the characteristics of small size and convenient operation, and can meet the immediate sterilization needs of a small number of instruments in some departments.

[0004] However, there are also some problems in the actual use of existing cassette sterilizers: when a small number of medical care instruments are placed in the sterilization cassette, there is a large amount of ineffective space. On the one hand, due to the insufficient utilization of the sterilization space, the device needs to consume the same amount of energy to disinfect and sterilize these ineffective spaces, thereby reducing the overall disinfection and sterilization efficiency; on the other hand, in order to achieve the disinfection and sterilization effect, steam needs to fill the entire sterilization cassette space, and the existence of ineffective space increases the steam consumption, resulting in waste of steam. Summary of the Invention

[0005] Based on this, it is necessary to provide a disinfection and sterilization device for medical care instruments in view of the problems of low disinfection and sterilization efficiency and resource waste existing in the current disinfection and sterilization process of medical care instruments.

[0006] The above object is achieved by the following technical solutions:

[0007] A disinfection and sterilization device for medical care instruments, the disinfection and sterilization device for medical care instruments includes:

[0008] A cassette sterilizer main body;

[0009] A sterilization cassette having a first inner cavity, the sterilization cassette is inserted into the cassette sterilizer main body during disinfection and sterilization;

[0010] A volume adjustment mechanism configured to divide the first inner cavity into a variable-volume instrument placement cavity and a variable-volume spare cavity;

[0011] A separating mechanism configured to separate the spare cavity into a first chamber with variable volume and two second chambers with variable volume, and the first chamber, the second chambers and the instrument placement cavity are not in communication; the second chambers are in communication with the instrument placement cavity.

[0014] Further, the first elastic member is a compression spring.

[0015] Further, a first handle is provided on each card strip.

[0016] Further, the sterilization box further has a second inner cavity; the separating mechanism includes two tightening rollers, both of the two tightening rollers are inserted into the second inner cavity and are arranged with parallel axes. A first separating belt is provided on each tightening roller, and the other end of the first separating belt is arranged on the plate surface of the adjusting plate facing the spare cavity side. The tightening roller can elastically rotate around its own axis to have a tendency to tension the first separating belt.

[0017] Further, a second elastic member is connected between each tightening roller and the sterilization box, and under the action of the second elastic member, the tightening roller has a tendency to rotate in the direction of tensioning the first separating belt.

The first ends of the separating members are arranged on the plate surface of the adjusting plate facing the spare cavity side, and the other ends are arranged on the inner side wall of the sterilization box.

[0020] Further, a handle is provided on the sterilization box.

[0021] The beneficial effects of the present invention are:

[0022] The present invention relates to a disinfection and sterilization device for medical care instruments. By providing a sterilization box and a cassette sterilizer body, during the process of disinfecting and sterilizing medical care instruments, the medical care instruments can first be placed in the sterilization box, and then the sterilization box can be placed in the cassette sterilizer body. Then, by means of the cassette sterilizer body introducing steam into the sterilization box, the medical care instruments are disinfected and sterilized. By providing a volume adjustment mechanism and a partitioning mechanism, according to the volume of the medical care instruments, the volume adjustment mechanism can adjust the instrument placement cavity to have a corresponding volume, and at the same time, the partitioning mechanism can adjust the volumes of the first chamber and the second chamber. When the cassette sterilizer body introduces steam into the sterilization box, the steam only enters the instrument placement cavity and the second chamber, thereby being able to reduce the volume occupied by the ineffective space, enabling the steam to be more concentrated in the instrument placement cavity. On the one hand, it helps to improve the disinfection and sterilization efficiency, and on the other hand, it can reduce the consumption of steam and reduce resource waste.

[0040] As Figures 1 to 8 shown, the disinfection and sterilization device for medical care instruments provided by an embodiment of the present invention is used for disinfecting and sterilizing medical care instruments, and is configured to include a cassette sterilizer body 1, a sterilization box 2 having a first inner cavity 2021, a volume adjustment mechanism 3, and a partition mechanism 4. The sterilization box 2 is inserted into the cassette sterilizer body 1 during disinfection and sterilization; the volume adjustment mechanism 3 is configured to divide the first inner cavity 2021 into an instrument placement cavity 20211 with a variable volume and a spare cavity 20212 with a variable volume; the partition mechanism 4 is configured to divide the spare cavity 20212 into a first chamber 20212a with a variable volume and two second chambers 20212b with a variable volume. The first chamber 20212a, the second chambers 20212b, and the instrument placement cavity 20211 are not communicated with each other; the second chambers 20212b are communicated with the instrument placement cavity 20211.

[0041] Specifically in this embodiment, the sterilization box 2 can be set to a cuboid structure, and the long side extends in the front-rear direction; the sterilization box 2 has a top cover 201 and a base 202, and the top cover 201 is buckled on the top of the base 202 during installation; the first inner cavity 2021 is formed on the top of the base 202, and the top of the first inner cavity 2021 is open, facilitating the placement of medical care instruments into the instrument placement cavity 20211. To facilitate the reception of steam, an air delivery channel 2024 is opened in the side wall of the base 202; an air inlet 2023 is opened on the outer side wall of the short side at the rear of the base 202, and the air inlet 2023 is communicated with both the air delivery channel 2024 and the cassette sterilizer body 1; an air vent 2025 is opened on the inner side wall of the long side of the base 202, and the air vent 2025 is communicated with the air delivery channel 2024, the instrument placement cavity 20211, and the second chambers 20212b, ensuring that steam can be introduced into the instrument placement cavity 20211 and the second chambers 20212b. To facilitate the discharge of air and steam in the sterilization box 2, an exhaust port 2026 is opened on the outer side wall of the short side at the rear of the base 202, and the exhaust port 2026 is communicated with the air delivery channel 2024 and is isolated from the air inlet 2023.

[0042] During use, first remove the top cover 201 from the base 202, and then adjust the volume of the instrument placement cavity 20211 to have a corresponding volume according to the volume of the medical care instrument to be disinfected and sterilized through the volume adjustment mechanism 3. When facing a medical care instrument with a small volume, the volume of the instrument placement cavity 20211 can be reduced through the volume adjustment mechanism 3, and the volume of the spare cavity 20212 will increase accordingly. When facing a medical care instrument with a large volume, the volume of the instrument placement cavity 20211 can be increased through the volume adjustment mechanism 3, and the volume of the spare cavity 20212 will decrease accordingly, ensuring that the instrument placement cavity 20211 fits tightly with the medical care instrument. The partition mechanism 4 also plays a role. When facing a medical care instrument with a small volume, the volumes of both the first chamber 20212a and the second chamber 20212b increase. When facing a medical care instrument with a large volume, the volumes of both the first chamber 20212a and the second chamber 20212b decrease.

[0043] Then snap the top cover 201 onto the top of the base 202, then insert the sterilization box 2 into the cassette sterilizer body 1, and then disinfect and sterilize the medical care instrument by passing steam into the sterilization box 2 through the cassette sterilizer body 1. During the process of passing steam into the sterilization box 2, the steam successively enters the instrument placement cavity 20211 and the second chamber 20212b through the air inlet 2023, the air delivery channel 2024, and the ventilation port 2025, and then discharges from the sterilization box 2 through the ventilation port 2025, the air delivery channel 2024, and the exhaust port 2026 in sequence; the air in the sterilization box 2 also discharges from the sterilization box 2 through the ventilation port 2025, the air delivery channel 2024, and the exhaust port 2026 in sequence.

[0044] In this way, since no steam is passed into the first chamber 20212a, a large amount of ineffective space originally generated due to the small volume of the medical care instrument in the sterilization box 2 can be significantly reduced. From the perspective of disinfection and sterilization efficiency, since the steam can act more concentratedly on the instrument placement cavity 20211, the disinfection and sterilization efficiency of the medical care instrument can be improved; in terms of resource utilization, since the volume of the chamber into which steam is passed is reduced, the steam consumption can be reduced, thereby reducing resource waste on the one hand and reducing energy consumption on the other hand.

[0045] Furthermore, the volume adjustment mechanism 3 is set to include an adjustment plate 301. The adjustment plate 301 is inserted into the first inner cavity 2021. The adjustment plate 301 divides the first inner cavity 2021 into an instrument placement cavity 20211 and a spare cavity 20212 located on both sides of the adjustment plate 301; a plurality of card slots 303 are provided on the inner side wall of the sterilization box 2; card strips 302 are provided at both ends of the adjustment plate 301. The card strips 302 can elastically slide along the direction parallel to the plate surface of the adjustment plate 301 and can be engaged with the card slots 303.

[0046] Specifically in this embodiment, when the adjusting plate 301 is installed, the plate surface is arranged parallel to the short-side side wall of the sterilization box 2, and the instrument placement cavity 20211 is located at the rear side of the spare cavity 20212. The multiple card slots 303 are evenly divided into two groups, and the two groups are respectively arranged on the inner side walls of the two long sides of the base 202. The card slots 303 in the same group are arranged at equal intervals along the length direction of the base 202, and the card slots 303 in different groups are correspondingly arranged. The card slots 303 extend along the height direction of the base 202. The card strip 302 extends along the height direction of the base 202 and can elastically slide along the width direction of the base 202. To facilitate the installation of the card strip 302, two installation slots 3011 are provided on the front plate surface of the adjusting plate 301. The two installation slots 3011 are respectively located at both ends of the adjusting plate 301. When installed, the card strip 302 is inserted into the installation slots 3011.

[0047] To facilitate the realization of the sliding of the card strip 302 along the width direction of the base 202, at least two sliding slots 3012 are penetrated and opened on the front plate surface of the adjusting plate 301 at the positions of the installation slots 3011. The sliding slots 3012 extend along the width direction of the base 202. The multiple sliding slots 3012 are arranged at equal intervals along the height direction of the base 202. At least two sliding rods 3013 are vertically arranged on the rear strip surface of the card strip 302. When installed, the sliding rods 3013 are respectively slidably inserted into the sliding slots 3012. At the rear end of each sliding rod 3013, a clamping plate 3014 is vertically arranged. The clamping plate 3014 is located in the instrument placement cavity 20211. The clamping plate 3014 and the card strip 302 respectively clamp on both sides of the adjusting plate 301.

[0048] During the use process, when facing medical care instruments with a relatively small volume, such as Figure 6 shown, two card strips 302 can be manually driven to approach each other first, so that the card strips 302 are disengaged from the card slots 303, and then the adjusting plate 301 is driven to move upward to reduce the volume of the instrument placement cavity 20211; when the adjusting plate 301 moves to a suitable position, the card strips 302 are released, and the card strips 302 are elastically engaged and snapped into the card slots 303 to lock the position of the adjusting plate 301.

[0049] Similarly, when facing medical care instruments with a relatively large volume, such as Figure 6 shown, two card strips 302 can be manually driven to approach each other first, so that the card strips 302 are disengaged from the card slots 303, and then the adjusting plate 301 is driven to move downward to increase the volume of the instrument placement cavity 20211; when the adjusting plate 301 moves to a suitable position, the card strips 302 are released, and the card strips 302 are elastically engaged and snapped into the card slots 303 to lock the position of the adjusting plate 301.

[0050] Further, to facilitate the elastic sliding of the card strip 302 along the direction parallel to the plate surface of the adjustment plate 301, a first elastic member is connected between each card strip 302 and the adjustment plate 301. Under the action of the first elastic member, the card strip 302 has a tendency to be tightly clamped with the card slot 303.

[0051] Specifically in this embodiment, the first elastic member is a compression spring 304. When installed, the compression spring 304 is inserted into the installation groove 3011, and extends along the width direction of the base 202 as a whole, and is connected between the adjustment plate 301 and the card strip 302. Under the action of the compression spring 304, the card strip 302 has a tendency to be tightly clamped with the card slot 303, thereby improving the connection strength between the card strip 302 and the card slot 303, and further improving the stability of the position of the adjustment plate 301.

[0052] Optionally, the number of compression springs 304 can be set to be multiple, and they are arranged side by side along the height direction of the base 202 to improve the evenness of the force on the card strip 302.

[0053] In a further embodiment, to improve the simplicity during operation, a first handle 3021 is provided on each card strip 302.

[0054] Specifically in this embodiment, the first handle 3021 has a C-shaped structure, and is provided on the front strip surface of the card strip 302, and the opening faces the card strip 302.

[0055] During use, by the way of driving the two first handles 3021 to approach each other with one hand at the same time, the two card strips 302 can be simultaneously disengaged from the corresponding card slots 303, and then by driving the two first handles 3021 to move, the adjustment plate 301 can be driven to move.

[0056] In other embodiments, to improve the sealing performance between the card strip 302 and the card slot 303, a sealing gasket 3022 is provided on the front strip surface of each card strip 302.

[0057] In some other embodiments, the sterilization box 2 further has a second inner cavity 2022; the separation mechanism 4 can be set to include two tightening rollers 401. The two tightening rollers 401 are both inserted into the second inner cavity 2022, and their axes are parallel. A first separation belt 402 is provided on each tightening roller 401, and the other end of the first separation belt 402 is provided on the plate surface of the adjustment plate 301 facing the spare cavity 20212 side. The tightening roller 401 can elastically rotate around its own axis to have a tendency to tension the first separation belt 402.

[0058] Specifically in this embodiment, the second inner cavity 2022 is formed at the top of the base 202 and is located on the front side of the first inner cavity 2021. The axis of the tightening roller 401 extends along the height direction of the base 202, and the two tightening rollers 401 are symmetrically inserted into the second inner cavity 2022. The belt surface of the first partition belt 402 is perpendicular to the bottom surface of the base 202, and the two first partition belts 402 are symmetrically arranged. The front end of the first partition belt 402 is fixedly arranged on the circumferential side wall of the tightening roller 401, and the rear end penetrates through the common side wall of the second inner cavity 2022 and the spare cavity 20212 and is vertically arranged on the front plate surface of the adjusting plate 301. To facilitate the installation of the first partition belt 402, four clamping seats 3015 are arranged on the front plate surface of the adjusting plate 301, and the rear end of the first partition belt 402 is fixedly clamped between the two clamping seats 3015. To improve the sealing performance between the second inner cavity 2022 and the spare cavity 20212, a sealing clip 5 is inserted at the position where the first partition belt 402 penetrates through the second inner cavity 2022 and the spare cavity 20212, and the first partition belt 402 passes through the sealing clip 5 during installation.

[0059] During use, when facing medical care instruments with a relatively small volume, such as Figure 6 as shown, at this time, the adjusting plate �01 moves upward, and the adjusting plate 301 synchronously drives the first partition belt 402 to move upward through the clamping seat 3015, so that the first partition belt 402 is released from the tightening roller 401, so as to always maintain the first chamber 20212a and the second chamber 20212b in an isolated state, and under the elastic rotation action of the tightening roller 401, the first partition belt 402 is always in a tensioned state, avoiding changing the volume of the first chamber 20212a due to the pressure difference between the first chamber 20212a and the second chamber 20212b, and avoiding affecting the disinfection efficiency of medical care instruments and the steam consumption.

[0060] Similarly, when facing medical care instruments with a relatively large volume, such as Figure 6 as shown, at this time, the adjusting plate 301 moves downward, and the adjusting plate 301 synchronously drives the first partition belt 402 to move downward through the clamping seat 3015, and the elastic rotation of the tightening roller 401 causes the first partition belt 402 to wind around the tightening roller 401, so as to always maintain the first chamber 20212a and the second chamber 20212b in an isolated state, and the first partition belt 402 is always in a tensioned state, avoiding changing the volume of the first chamber 20212a due to the pressure difference between the first chamber 20212a and the second chamber 20212b, and avoiding affecting the disinfection efficiency of medical care instruments and the steam consumption.

[0061] Further, to facilitate the elastic rotation of the tightening roller 401 about its own axis, a second elastic member is connected between each tightening roller 401 and the sterilization box 2. Under the action of the second elastic member, the tightening roller 401 has a tendency to rotate in the direction of tensioning the first separation belt 402.

[0062] Specifically in this embodiment, the second elastic member is a torsion spring and is connected between the tightening roller 401 and the base 202. Under the action of the torsion spring, the tightening roller 401 has a tendency to rotate in the direction of tensioning the first separation belt 402, so as to always tension the first separation belt 402 and avoid, after the adjusting plate 301 moves in place, due to the first separation belt 402 being in a slack state, when there is a pressure difference between the first chamber 20212a and the second chamber 20212b, the volume of the first chamber 20212a is changed under the action of the pressure difference, resulting in an impact on the disinfection efficiency of medical care instruments and the steam consumption.

[0063] In a further embodiment, to ensure the sealing performance of the sealing clip 5 and avoid the sealing surface of the sealing clip 5 being skewed due to the offset of the first separation belt 402, two alignment rollers 403 are symmetrically inserted into the second inner cavity 2022. The axis of the alignment roller 403 extends along the height direction of the base 202. As Figure 6 shown, one of the alignment rollers 403 is located above the left tightening roller 401, and the first separation belt 402 passes through the gap between the alignment roller 403 and the left tightening roller 401, and then passes through the sealing clip 5 in a direction parallel to the length direction of the base 202 under the guidance of the alignment roller 403, so as to avoid offset; the other alignment roller 403 is located above the right tightening roller 401, and the first separation belt 402 passes through the gap between the alignment roller 403 and the right tightening roller 401, and then passes through the sealing clip 5 in a direction parallel to the length direction of the base 202 under the guidance of the alignment roller 403, so as to avoid offset.

[0064] In other embodiments, the separation mechanism 4 can also be configured to include two separation members. Both separation members are inserted into the spare cavity 20212. The first ends of the separation members are both arranged on the surface of the adjusting plate 301 facing the spare cavity 20212, and the other ends are both arranged on the inner side wall of the sterilization box 2.

[0065] Specifically in this embodiment, the separation member can be configured as a second separation belt. When installed, the second separation belt is inserted into the spare cavity 20212 in a zigzag shape, and the rear end is clamped by two clamping seats 3015, and the front end is fixed on the front inner side wall of the base 202.

[0066] During use, when facing medical care instruments with a relatively small volume, the adjusting plate 301 moves in the direction of reducing the volume of the instrument placement cavity 20211. The adjusting plate 301 synchronously drives the second partition belt to move through the clamping seat 3015, so that a part of the second partition belt is released to maintain the first chamber 20212a and the second chamber 20212b in an isolated state.

[0067] Similarly, when facing medical care instruments with a relatively large volume, the adjusting plate 301 moves in the direction of increasing the volume of the instrument placement cavity 20211. The adjusting plate 301 synchronously drives the second partition belt to move through the clamping seat 3015, so that a part of the second partition belt is compressed to maintain the first chamber 20212a and the second chamber 20212b in an isolated state.

[0068] In other embodiments, the partition member can also be set as a telescopic plate. When installed, the telescopic plate is inserted into the spare chamber 20212, and the rear end is fixed on the front plate surface of the adjusting plate 301, and the front end is fixed on the inner side wall of the front side of the base 202.

[0069] During use, when facing medical care instruments with a relatively small volume, the adjusting plate 301 moves in the direction of reducing the volume of the instrument placement cavity 20211. The adjusting plate 301 synchronously drives the telescopic plate to extend to maintain the first chamber 20212a and the second chamber 20212b in an isolated state.

[0070] Similarly, when facing medical care instruments with a relatively large volume, the adjusting plate 301 moves in the direction of increasing the volume of the instrument placement cavity 20211. The adjusting plate 301 synchronously drives the telescopic plate to compress to maintain the first chamber 20212a and the second chamber 20212b in an isolated state.

[0071] In some other embodiments, to improve the simplicity of moving the sterilization box 2, a handle 203 is provided on the sterilization box 2.

[0072] Specifically in this embodiment, the handle 203 is of a C-shaped structure, and the two ends of the handle 203 are respectively hinged on the outer side walls of the two long sides of the base 202.

[0073] During use, the handle 203 can be driven to rotate around its hinge point to be located above the sterilization box 2, so as to facilitate carrying by hand.

[0074] In some other embodiments, to improve the simplicity of moving the sterilization box 2, second handles 204 are provided on both the front side wall of the base 202 and the front side wall of the top cover 201.

[0075] During use, the sterilization box 2 can be easily driven to move by holding the second handles 204.

[0076] In some other embodiments, for the convenience of forming a complete disinfection and sterilization process, the cartridge sterilizer body 1 is further provided with a heating system, a steam generation system, a control system, a safety device, a cooling system, etc. The heating system is responsible for generating heat to reach the required sterilization temperature in the instrument placement cavity 20211. It can adopt electric heating elements such as heating wires or heating plates.

[0077] The steam generation system usually consists of components such as a water tank and an evaporator. The water tank stores water for generating steam, and the evaporator heats and evaporates the water into saturated steam, and then transports the steam to the instrument placement cavity 20211 for sterilization.

[0078] The control system includes a control panel and various sensors. The control panel is used for operators to set sterilization parameters such as temperature, time, pressure, etc., and can display the operating status and relevant information of the device. The sensors monitor parameters such as temperature and pressure in the instrument placement cavity 20211 in real time, and feed back the data to the control system, so that the control system can automatically adjust and control according to the set value to ensure the safety and effectiveness of the sterilization process.

[0079] The safety device is set to ensure the safety of operators and equipment. It can usually be set to include a safety valve, a door safety lock, a temperature protection device, etc. The safety valve is used to prevent the pressure in the instrument placement cavity 20211 from being too high; the door safety lock can prevent the top cover 201 from being accidentally opened during the sterilization process; the temperature protection device can automatically cut off the power supply of the heating system when the temperature in the instrument placement cavity 20211 exceeds the set upper limit.

[0080] The cooling system usually adopts air cooling or water cooling methods, and reduces the temperature of the instrument placement cavity 20211 and medical care instruments through a fan or circulating water, so as to take out the medical care instruments as soon as possible and perform the next operation.

[0081] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combinations of these technical features do not conflict, they should be considered as the scope recorded in this specification.

[0082] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
