Description

Technical Field

[0001] The invention relates to the technical field of laboratory equipment cleaning, and in particular to a drying and disinfecting device for clinical microbiology test smears and a use method thereof. Background Art

[0002] In clinical microbiology research, observation and examination of smears under a microscope is a key technology in pathogenic microbiology testing. Smears are made by evenly applying the loose tissues of the organism to a slide to make a slide specimen. In this way, pathogenic bacteria can be identified promptly and quickly, providing an important basis for clinical diagnosis and providing accurate evidence for subsequent treatment.

[0003] Biological test smears need to be dried and cleaned when used, and existing drying and disinfection devices usually leave the test smears to dry inside them (such as Fig.12 As shown in the figure, the drying and heating efficiency of the test smear is low, which prolongs the disinfection and drying cycle of the test smear. At the same time, the contact between the smear and other supporting structures cannot be effectively disinfected and dried. This method has a great influence on the disinfection and drying effect of the smear, and thus interferes with the subsequent test results. In addition, since the smear is made of thinner glass, the prior art usually uses fixed grids to lay the smears flat, which occupies a large space, is not conducive to the batch processing operation of the smear, and affects the turnover efficiency of the smear. Summary of the invention

[0004] In view of the defects existing in the above-mentioned prior art, the present invention aims to provide a drying and disinfecting device for clinical microbiology test smears and a method of using the same, so as to solve the problems existing in the above-mentioned background technology.

[0005] The present invention takes the cleaning effect and batch processing quantity of the smear as the starting point, designs a disc-type rotating placement rack to replace the traditional flat placement structure, and utilizes the reaction force formed by the spraying of high-pressure disinfectant or disinfectant gas from the bottom of the placement rack to make the placement rack and the central axis seat rotate synchronously, thereby realizing dynamic drying and disinfection processing. The centrifugal force of the rotation of the placement rack on the smear and the increased buoyancy of the disinfectant on the smear cause the smear to move horizontally and float slightly in the clamping position, thereby realizing all-round and thorough cleaning and disinfection of the smear, greatly improving the cleaning and disinfection effect.

[0006] The present invention achieves the above technical objectives by adopting the following technical solutions: On the one hand, the present invention discloses a drying and disinfecting device for clinical microbiology test smears, comprising a cylindrical container and a matching upper cover, the cylindrical container is connected with a filling pipe and a discharge pipe, and further comprises: The rotary cleaning and disinfecting mechanism is rotatably connected to the cylindrical container, the smear is placed on the rotary cleaning and disinfecting mechanism, and the disinfectant or gas is injected into the cylindrical container through the filling tube, and the smear is cleaned by the rotary cleaning and disinfecting mechanism; A sterilization and disinfection mechanism is arranged on the inner top wall of the upper cover and is used to sterilize the smear; The drying mechanism is arranged on the outer top of the upper cover and is connected with the interior of the cylindrical container, and is used for drying the smear.

[0007] As a further preferred solution of the above technical solution: the rotary cleaning and disinfection mechanism includes a central axis seat and a placement rack, the central axis seat is rotatably connected to the cylindrical container through a mounting base, and the interior of the central axis seat is connected to the mounting base, and a plurality of placement racks are provided, and the plurality of placement racks are circumferentially distributed on the outer side of the central axis seat.

[0008] A further preferred solution is that the central shaft seat is in the shape of a hollow cylinder, and a plurality of liquid outlets are provided at its lower end.

[0009] Based on the above technical solution, further, the placement rack is connected to the outer wall of the central axis seat at an angle, wherein the placement rack forms an angle of 75° to 85° with the horizontal direction.

[0010] Based on the above technical solution, further, a plurality of liquid spray holes are opened on one side of the placement rack, each of the liquid spray holes is connected with the flow hole in the placement rack, and the flow hole is connected with the corresponding liquid outlet.

[0011] A further preferred solution is that the placement rack is divided into a plurality of clamping positions by elastic members, and the smear is limited by the clamping positions.

[0012] As a further preferred embodiment, the elastic member is S-shaped, the upper end and the lower end of the elastic member are both connected to the placement frame, and two adjacent smears are respectively abutted against two sides of the elastic member.

[0013] A further preferred solution is that two rows of mutually parallel and corresponding limiting protrusions are respectively provided at the upper end and the lower end of the placement rack, and the smear is clamped by the two rows of limiting protrusions.

[0014] Based on the above technical solution, further, a buffer is provided on the placement rack, and the buffer is in contact with the smear on the side away from the central axis seat, so that the smear is protected by the buffer.

[0015] On the other hand, the present invention also discloses a method for using a drying and disinfecting device for clinical microbiology test smears, comprising the following steps: S1: Insert the smear into the clamping position of the placement rack and turn on the ultraviolet light for sterilization and disinfection; S2: inject disinfectant into the cylindrical container, and the disinfectant enters the placement rack and is sprayed out from the spray hole. When the disinfectant is sprayed out, it pushes the placement rack in the opposite direction, so that the placement rack drives the central axis seat to realize synchronous rotation. Under the action of centrifugal force, the smear moves outward in the clamping position, so that the dead corner of the smear blocked by the clamping position can be cleaned and disinfected; S3: As the amount of disinfectant in the cylindrical container increases, the rotation speed of the placement rack slows down, and the disinfectant sprayed from the spray hole forms a vortex at the bottom of the smear, which effectively cleans and disinfects the smear. The increase in the amount of disinfectant increases the buoyancy of the smear, causing the smear to float in the clamping position, and fully disinfecting the blocked part where the smear contacts the strip block; S4: When the disinfectant completely immerses the smear, drain the disinfectant after it is fully immersed, and then pass pure sterile water into the cylindrical container to rinse the smear. After draining the pure sterile water, dry the smear.

[0016] Compared with the prior art, the advantages of the present invention are embodied in the following aspects: 1. The present invention provides a rotary cleaning and disinfecting mechanism, which includes a placement rack and a central axis seat, and the central axis seat is rotatably connected to the cylindrical container. When the disinfectant is passed into the central axis seat under high pressure, it is sprayed out from the spray hole at the lower end of the placement rack. The reaction force of the disinfectant spraying pushes the placement rack to synchronously drive the central axis seat to rotate. The vortex formed by the disinfectant at the bottom of the placement rack fully cleans and disinfects the smear. When the placement rack rotates, the smear moves to the side away from the central axis seat under the action of centrifugal force, so that the dead corner of the smear blocked by the clamping position can be cleaned and disinfected. As the height of the disinfectant in the cylindrical container rises, the buoyancy of the smear increases. Under the limiting effect of the inclination angle of the placement rack and the friction with the clamping position, the smear floats up slightly in the clamping position, so that a gap is formed between the bottom of the smear and the lower part of the clamping position, and at the same time, the blocked part of the smear is exposed, thereby achieving all-round disinfection to eliminate blind spots and improve the disinfection effect.

[0017] 2. The present invention utilizes a design concept in which multiple placement racks are circumferentially arranged on a central axis seat, replacing the design of a traditional flat-lay drying and disinfection device, thereby greatly increasing the number of smears dried and disinfected in a single time. At the same time, the connection method in which the placement racks are tilted at a certain angle to the central axis seat not only improves the space utilization rate for smear placement, but also increases the irradiation area of ​​ultraviolet light sterilization and drying, which is beneficial to improving the efficiency of sterilization and drying treatment.

[0018] 3. The present invention uses an "S"-shaped elastic member to divide the placement rack into multiple clamping positions, which can realize elastic limitation of the smear on the placement rack. The elastic member is an elastic memory steel wire. When the smear moves on the clamping position due to the centrifugal force, the outer elastic member adjacent to it will be squeezed and deformed, which can effectively buffer the movement inertia of the smear and prevent the smear from being damaged due to inertia. A buffer member (the present invention uses an airbag structure) is arranged between the outermost smear and the placement rack to provide buffer protection for the outermost smear when it moves.

[0019] 4. The present invention is provided with a sterilization and disinfection mechanism (an ultraviolet lamp in the present invention) and a drying mechanism at the upper cover, and the cleaning and disinfection of the disinfectant and the sterilization and disinfection of the ultraviolet lamp are used in combination, and the smear after disinfection can be aseptically rinsed and dried, which greatly improves the practicality of the present invention.

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0023] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention. Embodiment 1:

[0024] Reference Figure 1-8 The present invention provides a drying and disinfecting device for clinical microbiology test smears, comprising a cylindrical container 1, the cylindrical container 1 is provided with an upper cover matched therewith, the bottom of the cylindrical container 1 is fixedly connected with four legs, the lower end of the cylindrical container 1 is connected with a filling pipe 11 and a discharge pipe 12, wherein one end of the filling pipe 11 is connected to the bottom of the cylindrical container 1, and the other end thereof extends horizontally, and the discharge pipe 12 is connected to the side wall of the lower end of the cylindrical container 1. The drying and disinfecting device of the present invention also comprises a rotary cleaning and disinfecting mechanism 2, a sterilizing and disinfecting mechanism 3 and a drying mechanism 4, the rotary cleaning and disinfecting mechanism 2 is rotatably connected to the cylindrical container 1, the smear 5 is placed on the rotary cleaning and disinfecting mechanism 2, disinfectant or gas is injected into the interior of the cylindrical container 1 by the filling pipe 11, the smear 5 is cleaned by the rotary cleaning and disinfecting mechanism 2, the sterilizing and disinfecting mechanism 3 is arranged on the inner top wall of the upper cover, and is used for sterilizing the smear 5, the drying mechanism 4 is arranged on the outer top of the upper cover and is connected with the interior of the cylindrical container 1, and is used for drying the smear 5.

[0025] like Figure 6-7As shown, the rotary cleaning and disinfection mechanism 2 includes a central axis seat 21 and a placement rack 22. The central axis seat 21 is rotatably connected to the cylindrical container 1 through a mounting base 6. The interior of the central axis seat 21 is connected to the mounting base 6. A plurality of placement racks 22 are provided. In order to increase the number of batches of smears 5, the placement rack 22 is circumferentially connected to the outer side of the central axis seat 21. The placement rack 22 is an annular rectangular and adopts an insert-type design. A card slot 223 is provided at the upper end of the placement rack 22. Three smears 5 are placed on each placement rack 22. The smears 5 are inserted into the card slot 223 from top to bottom for limiting. In this embodiment, the placement rack 22 and the central axis seat 21 can be fixedly connected or detachably connected; further, the mounting base 6 is fixedly connected to the cylindrical container 1, and the mounting base 6 and the central axis seat 21 are rotatably connected through a bearing. The disinfectant or gas enters the central axis seat 21 through the center hole of the mounting base 6 from the filling tube 11.

[0026] Specifically, a plurality of liquid outlets 211 are provided at the circumferential direction of the lower end of the central shaft seat 21, and a plurality of liquid spray holes 221 are provided at one side of the lower end of the placement frame 22. Figure 5 and Figure 8 At the same time, a flow hole intersecting with a plurality of liquid spray holes 221 is provided at the lower end of the placement rack 22, and one end of the flow hole close to the central axis seat 21 is connected to the liquid outlet 21. When the disinfectant enters the interior of the central axis seat 21, it is sprayed out from each liquid spray hole 221 through the flow hole. At this time, the disinfectant generates a reaction force on the placement rack 22 during the spraying process. The reaction force on each placement rack 22 causes the central axis seat 21 to rotate. The rotating placement rack 22 in the cylindrical container 1 makes the disinfectant in a flowing state, and the multiple liquid outlets 211 at the lower end of the placement rack 22 make the disinfectant here form a vortex shape, thereby more fully flushing and disinfecting the smear 5.

[0027] In this embodiment, considering that the sterilization and disinfection mechanism 3 and the drying mechanism 4 are located at the top of the cylindrical container 1, in order to further increase the effective irradiation area of ​​sterilization and drying, each placement rack 22 is obliquely connected to the outer wall of the central axis seat 21, and the placement rack 22 is at an angle of 75°~85° with the horizontal direction, preferably at an angle of 80°. This angle can ensure that the smears 5 on each placement rack 22 will not contact and interfere with each other, and can ensure that the smears 5 are sterilized and dried over a larger area, and can also meet the requirements of placing more smears 5 at the same time for batch processing, which greatly improves the processing efficiency of the smears 5 and is conducive to the turnover of the smears 5.

[0028] like Figure 4As shown, the sterilization and disinfection mechanism 3 includes three groups of ultraviolet lamps, which are evenly installed on the inner top wall of the upper cover. The switch of the ultraviolet lamp is connected to the outside of the upper cover, and the operator controls the ultraviolet lamp through the switch according to actual needs; the drying mechanism 4 is provided with three groups, which includes a connecting shell 41, the connecting shell 41 is connected to the upper cover, the upper end of the connecting shell 41 is provided with a connecting port 42, and the lower end thereof is provided with a plurality of air outlets. When in use, the drying equipment is connected to the connecting port 42. When the drying equipment is working, the heated gas is discharged from the air outlet into the cylindrical container 1 through the connecting port 42 to dry the smear 5 on the placement rack 22.

[0029] As more disinfectant enters the cylindrical container 1, the disinfectant gradually submerges the placement rack 22 from bottom to top, and the rotation speed of the placement rack 22 slows down. However, the disinfectant sprayed from each liquid outlet 211 will form a vortex at the bottom of the smear 5, thereby more fully disinfecting the smear 5. As more disinfectant is added, the buoyancy of the smear 5 increases, causing the smear 5 to float slightly on the placement rack 22, thereby cleaning and disinfecting the dead corner where the lower end of the smear 5 contacts the placement rack 22. Finally, the disinfectant fills the cylindrical container 1 and completely submerges the smear 5, allowing the smear 5 to be soaked for a set time to achieve a sufficient disinfection effect. Embodiment 2:

[0030] On the basis of the above-mentioned first embodiment, in order to prevent the plurality of smears 5 on each rack 22 from moving due to the centrifugal force when the rack 22 rotates, thereby causing the smears 5 to be scratched and damaged, the structure of the rack 22 is further improved as follows.

[0031] like Figure 8-11 As shown, a plurality of elastic members 7 are connected to the placement rack 22 at intervals, and the placement rack 22 is divided into a plurality of clamping positions, and each smear 5 is placed at a corresponding clamping position; in this embodiment, the elastic member 7 is S-shaped and is made of elastic memory steel wire. It deforms when subjected to force and returns to its original shape when not subjected to force. The upper and lower ends of the elastic member 7 are fixedly connected to the placement rack 22, and the left and right sides of the elastic member 7 are respectively in contact with two adjacent smears 5, and the elastic member 7 is used to limit the static smear 5 in the horizontal direction; when the placement rack 22 rotates, the smear 5 is deformed due to the separation Due to the centrifugal force, the smear 5 squeezes the elastic member 7 located on the outside thereof to cause it to deform. The elastic member 7 here acts as a buffer inertia for the moving smear 5 to prevent the smear 5 from moving too much and being damaged. At the same time, a buffer member 8 is provided on the frame where the smear 5 on the outermost side (i.e., the side away from the central axis seat 21) contacts the placement rack 22. The buffer member 8 in this embodiment is an air bag. The outermost smear 5 will move toward the outermost side of the placement rack 22 under the action of centrifugal force. The outermost smear 5 is protected by the provision of the air bag to prevent it from colliding with the placement rack 22 and being damaged.

[0032] Furthermore, two rows of mutually parallel and corresponding limiting protrusions 224 are respectively provided at the upper and lower ends of the placement rack 22. Figure 8-10 , the smear 5 is clamped by two rows of limiting protrusions 224. In this embodiment, the limiting protrusions 224 are a plurality of strip blocks facing each other up and down, and two rows of strip blocks are respectively arranged at the upper and lower ends of the placement rack 22, each strip block has the same shape and corresponds to the position, and a gap for clamping the smear 5 is formed between the two rows of strip blocks. When the smear 5 is inserted from top to bottom in the placement rack 22 in the clamping position, the bottom end and the upper end of the smear 5 are respectively located in the gap between the corresponding strip blocks, and the smear 5 is effectively limited, and the contact area with the smear 5 can also be reduced, so as to avoid large-area obstruction of the disinfection and cleaning of the smear 5.

[0033] It should be further supplemented that a layer of nanosponge (not shown in the drawings) is provided in the slot 223 of the placement rack 22 (including each contact surface of the two rows of strip blocks in contact with the smear 5), and the nanosponge is used to protect the smear 5 in each clamping position to avoid wear of the smear 5 when it moves. Embodiment three:

[0034] A drying and disinfecting device for clinical microbiology test smears adopts a disc-shaped design in which a placement rack 22 and a central shaft seat 21 are connected, which can increase the number of single batch processing of smears 5 and convert traditional static disinfection and drying treatment into dynamic treatment, greatly improving the effect and efficiency of drying and disinfecting the smears 5. In practical application: First, insert the smear 5 to be disinfected into the clamping position of the placement rack 22 in sequence, and buckle the upper cover on the cylindrical container 1, turn on the ultraviolet lamp to start disinfection; Then, a high-pressure disinfectant (or a high-pressure disinfectant gas, either one of the two can be selected) is connected to the filling tube 11, and the disinfectant enters the central shaft seat 21 from the mounting base 6, and then is sprayed out from each liquid spray hole 221 after passing through the flow hole from the liquid outlet 211. When the disinfectant is sprayed, a reaction force is formed on each placement rack 22, pushing each placement rack 22 to move in the opposite direction of the disinfectant spraying direction, so that each placement rack 22 drives the central shaft seat 21 to rotate clockwise, and at this time, the ultraviolet lamp is cooperated to realize dynamic and rapid disinfection of the smear 5; When the disinfectant in the cylindrical container 1 rises to the lower end of the placement rack 22, the disinfectant sprayed from each liquid outlet 211 will form a vortex at the lower end of the smear 5. The vortex disinfectant can clean the dynamic smear 5 more thoroughly. Since the rotation of the placement rack 22 will form a centrifugal force on the smear 5 placed thereon, each smear 5 will move outward in the clamping position. During the horizontal movement of the smear 5, the dead corner that was originally in contact with the strip block will be cleaned and disinfected. As the height of the disinfectant in the cylindrical container 1 gradually increases, the resistance of the disinfectant to the placement rack 22 will gradually slow down the rotation speed of the placement rack 22, and the movement amplitude of the smear 5 will gradually decrease. At this time, the buoyancy of the disinfectant on the smear 5 gradually increases, causing the smear 5 to float slightly in the gap between the strip blocks at the bottom of the placement rack 22, and the shielded part where the smear 5 contacts the strip block is cleaned and disinfected. When the disinfectant completely submerges the smear 5, the smear 5 is fully disinfected by soaking for a period of time. After the disinfectant is discharged from the discharge pipe 12, pure sterile water can be introduced into the cylindrical container 1 through the filling pipe 11 and the connecting port 42 to rinse the smear 5. After rinsing, the pure sterile water is discharged from the discharge pipe 12, and then a drying device is connected to the connecting port 42 to dry the smear 5.

[0035] It should be noted that the present invention can be used to disinfect the smear 5 with high-pressure disinfectant liquid and high-pressure disinfectant gas, use ultraviolet lamps to perform static and dynamic sterilization and disinfection throughout the process, and cooperate with drying equipment to dry the smear 5 after disinfection and cleaning, which effectively improves the drying and disinfection effect and efficiency of the smear 5, provides new ideas and directions for the efficient disinfection and drying operations of clinical microbiology test smears, and can meet the needs of rapid batch processing of clinical microbiology test smears.

[0036] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
