[0019] The beneficial effects of this utility model include: 1. By placing the protective cover on the drying table, it can prevent the aerosol generated during the instrument drying process from spreading outside the protective cover. The placement plate is equipped with a drain hole for water filtration, which can dry wet instruments with a lot of water. Under the negative pressure generated by gravity and negative pressure suction components, the liquid on the instrument flows directly into the guide hood through the drain hole, which can be used to dry instruments with a lot of water. The air jet component can blow air onto the instruments to be dried on the placement plate to accelerate the drying of the instruments. The airflow enters through the operation hole, removes the moisture from the instruments and the water vapor in the cover, and flows into the guide hood through the drain hole for collection. This can effectively reduce the leakage and diffusion of aerosols and solve the problem that the protective cover and the operation table are in an open state, which makes it easy for aerosols to spread.

[0020] 2. The negative pressure suction component of this utility model has a simple structure. It centrally stores the adsorbed water through a water storage tank and generates negative pressure through a negative pressure suction pump to attract the moisture on the instrument, thereby achieving the purpose of drying the instrument.

[0021] 3. The jet assembly has a simple structure. It generates compressed air through an air pump, which is then sprayed out through an air gun and blown onto the instrument to be dried. It is easy to adjust and position the air to accelerate the drying of the instrument.

[0023] 5. The operating holes on the movable door panel allow the operator to easily reach inside the protective cover to operate the jet assembly;

[0024] 6. The protruding handle on the movable door panel can abut against the outer wall of the protective cover after the movable door panel is opened, preventing the movable door panel from sticking to the outer wall of the protective cover after it is opened, making it difficult to close the movable door panel;

[0025] 7. The sealing strip can seal the movable door panel and the protective cover when the movable door panel is closed, preventing aerosol from spreading from the gap at the connection between the movable door panel and the protective cover;

[0026] 8. The sterilization components can sterilize the instruments, further ensuring their sterility; the instruments are sterilized by irradiating them with ultraviolet lamps, which is convenient to use.

[0027] 9. The lighting unit can illuminate the inside of the protective cover, illuminating the surface of the instrument and facilitating targeted drying of parts of the instrument with excessive moisture.

[0028] 10. The mesh structure of the placement plate has many drainage holes, which reduces the weakening of the negative pressure generated by the negative pressure suction component. At the same time, it facilitates the flow of moisture from the instruments to the flow guide hood under its own weight, thus improving the drying effect.

[0029] The negative pressure instrument drying device of this utility model generates negative pressure through a negative pressure suction component. Airflow enters through the operation hole, carrying away the moisture of the instrument and the water vapor inside the protective cover. The airflow flows into the guide cover for centralized treatment through the drain hole. The protective cover is placed on the placement plate, so the water vapor generated by the moisture on the instrument will not diffuse and leak outside the protective cover. This can solve the problem that the protective cover and the operation table are in an open state, which leads to the easy diffusion of aerosols. Attached Figure Description

[0037] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0038] In the background technology, the negative pressure semi-open instrument drying table is in an open state between the table and the protective cover. During the drying process, the airflow blown out by the compressed air gun will generate aerosols and be blown out of the protective cover and diffused, which can be easily inhaled and affect health. Moreover, the moisture on the instrument can only be blown into water vapor and then sucked out by the fan assembly above. When there is a lot of water on the instrument, the drying is slow.

[0039] This utility model relates to a negative pressure instrument drying device for drying medical devices. A protective cover 5 is installed on the drying table 1 to prevent aerosols generated during the drying process from diffusing outside the protective cover 5. A drain hole 21 is provided on the placement plate 2, allowing liquid on the instruments to flow directly into the guide hood 3 under the negative pressure generated by gravity and the negative pressure suction component 4. This is suitable for drying instruments with a high water content. An air jet component 6 blows air onto the instruments on the placement plate 2 to accelerate the drying process. Airflow enters through the operating hole 54, carrying away moisture from the instruments and water vapor from inside the cover, which then flows into the guide hood 3 through the drain hole 21 and is collected. This effectively reduces aerosol leakage and diffusion, solving the problem of easy aerosol diffusion caused by the open state of the protective cover 5 and the operating table.

[0040] A negative pressure instrument drying device, specifically, such as Figure 1-3 As shown, the device includes a drying table 1, a negative pressure suction assembly 4, a protective cover 5, and a jet assembly 6. The drying table 1 includes a placement plate 2 forming the table surface and a flow guide hood 3 located below the placement plate 2 and open at the top. Multiple drainage holes 21 are provided on the placement plate 2, and the open opening of the flow guide hood 3 covers the multiple drainage holes 21 corresponding to the placement plate 2. The protective cover 5 is connected to the drying table 1 corresponding to the placement plate 2, forming a closed chamber for drying the device. Specifically, the placement plate 2 forms the bottom surface of the protective cover 5, and the protective cover 5 has an operating hole 54, which, together with the drainage holes 21, forms... Convection; the jet assembly 6 is located on the drying table and is used to blow air onto the instruments on the placement plate 2, blowing the moisture on the instruments into water vapor through compressed air, which is then sucked in and discharged by the negative pressure suction assembly 4, accelerating the drying of the instruments; its operation port 54 is also used for the operator to put their hand into the protective cover 5 to operate the jet assembly 6 and adjust the size of the operation port 54. It is equipped with a redundant gap, so that there is still a gap for air intake when the operator's arm is put into the operation port 54. The air intake port 51 is on the operator's side, and the airflow enters the protective cover from the outside to the inside through the air intake port 51, so that the aerosol is not easily diffused and inhaled by the operator.

[0041] In some embodiments, the protective cover 5 is detachably connected to the drying table 1; including one side of the protective cover 5 being hinged to the drying table 1, and when in use, the protective cover 5 is opened by rotating around the hinge and the instrument is placed on the placement plate 2; in another embodiment, the protective cover 5 is placed directly on the surface of the drying table 1, and when in use, the protective cover 5 is lifted and the instrument is placed on the placement plate 2.

[0042] In one embodiment, such as Figure 1 As shown, the flow guide shroud 3 is funnel-shaped; the negative pressure suction assembly 4 includes a water storage tank 41 connected to the bottom of the flow guide shroud 3 and a negative pressure suction pump 42 connected to the top of the water storage tank 41; specifically, the negative pressure suction pump 42 is connected to the top wall of the water storage tank 41 through a pipeline to reduce the direct suction of water into the negative pressure suction pump 42, and the bottom of the water storage tank 41 is provided with a water outlet valve.

[0043] This drying device also includes an air jet assembly 6, such as Figure 1-2 As shown, the jet assembly 6 includes an air pump 61 located within the drying table 1 and an air gun 62 connected to the air pump 61 via a pipeline. Preferably, the air gun 62 is connected to the air pump 61 via a spiral hose, which automatically contracts and expands during the movement of the air gun 62. The jet assembly 6 has a simple structure; compressed air is generated by the air pump 61 and sprayed out through the air gun 62, blowing onto the instrument to be dried. This allows for easy adjustment of the compressed air flow and precise positioning of the airflow, accelerating the drying of the instrument. Preferably, the protective cover 5 is equipped with a bracket for mounting the air gun 62. The bracket can be located on either the inner or outer wall of the protective cover 5. The bracket can be a hook, which has a simple structure and facilitates the hanging and removal of the air gun 62.

[0044] In a preferred embodiment, such as Figure 1-2 As shown, the protective cover 5 includes a movable door panel 52, one side of which is hinged to the protective cover 5. In one specific embodiment, the movable door panel 52 forms a side wall of the protective cover 5, and its top is hinged to the protective cover 5. The movable door panel 52 can be opened and placed on the top wall of the protective cover 5 in an open state, facilitating the continuous placement of multiple instruments. The protective cover 5 with the movable door panel 52 can be fixed to the drying table 1, and it is more convenient to directly open the movable door panel 52 and place the instruments on the placement plate 2.

[0045] Based on the protective cover 5, including the movable door panel 52, such as Figure 2 As shown, the movable door panel 52 is provided with the aforementioned operating hole 54, which is used for the operator to reach into the protective cover 5 to operate the jet assembly 6; the top wall of the protective cover 5 is provided with multiple air inlets 51, which are used to form convection with the drain hole 21, so that air does not need to be introduced through the operating hole 54.

[0046] Based on the protective cover 5, including the movable door panel 52, such as Figure 1-2 As shown, the movable door panel 52 is provided with a protruding handle 53. The handle 53 can be used to pull the movable door panel 52 to rotate around the hinge to open the protective cover 5. The protruding handle 53 can abut against the outer wall of the protective cover 5 after the movable door panel 52 is opened, so as to prevent the movable door panel 52 from sticking to the outer wall of the protective cover 5 after it is opened, making it difficult to close the movable door panel 52.

[0047] The protective cover 5 includes a movable door panel 52. A sealing strip is provided at the edge of the movable door panel 52 or at the edge of the protective cover 5 abutting against the movable door panel 52. This sealing strip seals the connection between the protective cover 5 and the movable door panel 52 when the movable door panel 52 is closed. The sealing strip effectively seals the connection between the movable door panel 52 and the protective cover 5, preventing aerosols from spreading from the gaps at the joint between them.

[0050] In a preferred embodiment, such as Figure 2-3 As shown, the placement plate 2 has a mesh structure, for example, a mesh grid with a certain height, which has a certain strength to support the instruments. The drainage hole 21 forms a large total channel area, and the placement plate 2 occupies a small blocking area on the plane. This reduces the negative pressure generated by the negative pressure suction component 4, while facilitating the flow of moisture from the instruments to the guide hood 3 under its own weight, thus improving the drying effect.

[0051] In actual use, pull handle 53 to open movable door panel 52, place the medical device to be dried, close movable door panel 52, start negative pressure suction pump 42, and the operator uses air gun 62 to fire compressed air at the device through operating hole 54, blowing the water towards drain hole 21. The water vapor formed by the water on the device can be sucked away by the negative pressure generated by negative pressure suction pump 42 through drain hole 21. A large amount of water is stored in water tank 41 for centralized treatment. The protective cover 5 effectively reduces or even eliminates the diffusion of aerosols outside the protective cover 5. The placement plate 2 is provided with drain hole 21 for water filtration. Negative pressure suction pump 42 generates negative pressure below placement plate 2, which is in the same direction as gravity, and has a good drying effect on devices with high humidity.
