Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sampling, in particular to a portable nosocomial infection environmental hygiene monitoring sampling box. Background Art
[0002] Hospital environmental hygiene monitoring is an important part of controlling hospital infections. The monitoring results can be used to evaluate the effectiveness of routine environmental cleaning and disinfection and help evaluate the effectiveness and scientificity of hospital disinfection equipment and disinfectants. According to relevant national regulations, medical institutions should conduct regular environmental hygiene monitoring, and environmental microbial assessment methods and standards are given.
[0003] Hospital infection management professionals need to conduct hospital disinfection and sterilization effectiveness and environmental hygiene monitoring in key clinical departments every quarter. During the monitoring process, they need to use culture dishes, various sampling test tubes, alcohol lamps, sampling specification plates and other items to collect specimens. Because there are many sampling and testing tools to carry, they often need to use hand-held or dragged boxes to place tools. After collecting samples at different locations, they are tested directly or brought back to the laboratory for testing. When people move the box, the box will shake or tilt, and the container placed inside may cause the internal liquid to leak out due to the tilt, which will cause the inside of the box and other adjacent containers to be contaminated, which is not conducive to environmental monitoring. Utility Model Content
[0004] The utility model aims to provide a portable nosocomial infection environmental hygiene monitoring sampling box to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.
[0005] The technical solution adopted to solve the above technical problems is as follows: a portable hospital infection environmental hygiene monitoring sampling box includes: a box body, a storage compartment is arranged on the top of the box body; a balance frame, a circular arc bar is arranged on the bottom, and a first circular arc groove is opened on the bottom wall of the storage compartment for the circular arc bar to be embedded and slide; a storage box, a counterweight block is installed in the middle of the bottom, and both sides of the storage box are rotatably connected to the balance frame, and the rotation center line of the storage box relative to the balance frame is perpendicular to the rotation center line direction of the balance frame relative to the box body.
[0006] The technical solution has at least the following beneficial effects: the container that collects more liquid can be fixed inside the storage box. During the transportation of the box, the storage box can swing in one direction relative to the balance frame, and the balance frame can swing in another direction relative to the box, so that the storage box can be tilted at a certain angle in the 360-degree direction to cope with the tilt of the box. When the box is tilted, the storage box can keep the opening facing upward under the action of the counterweight, so that the container in the storage box is not easy to tilt with the box, reducing the situation of liquid leakage caused by the tilt of the container; when the box shakes, under the inertia of the storage box, the amplitude of the shaking of the storage box will be smaller than the amplitude of the shaking of the box, thereby reducing the situation of liquid leakage caused by the tilt of the container, reducing the situation of contamination of the inside of the box or other adjacent containers caused by liquid leakage, and ensuring the smooth progress of environmental monitoring. In addition, the container in the storage box can be better kept in a state with the opening facing upward, making the internal liquid more stable and less likely to tilt, and the upper surface of the internal liquid can maintain a small contact area with the air inside the container, reducing the influence of air on the liquid components, thereby ensuring the accuracy of the liquid detection results.
[0007] As a further improvement of the above technical solution, both ends of the first arc groove penetrate the top of the storage compartment and are detachably mounted with mounting blocks. By removing the mounting blocks, the arc bar can be easily embedded in the arc groove, and the arc bar is restricted by the mounting blocks at both ends during the sliding process of the first arc groove and will not leave the range of the first arc groove, thereby ensuring the stability of the swing of the storage box, and the structure is simple and easy to manufacture.
[0008] As a further improvement of the above technical solution, first springs are provided between both ends of the arc strip and the mounting blocks on the corresponding sides. When the balancing frame swings greatly relative to the box body, the arc strip slides in the first arc groove until it is ready to contact the mounting block on the corresponding side, and it will first press the first spring between the two, and the compression of the first spring will buffer the swing of the arc strip, thereby buffering the large swing of the balancing frame relative to the box body.
[0009] As a further improvement of the above technical solution, a second arc groove perpendicular to the first arc groove is provided at the bottom of the storage box, and a slider sliding in the second arc groove is provided at the top of the balance frame. When the storage box swings relative to the balance frame, the slider is restricted to slide in the second arc groove, so that the storage box swings relative to the balance frame within a certain range, thereby ensuring the stability of the swing of the storage box, and having a simple structure and being easy to manufacture.
[0010] As a further improvement of the above technical solution, a second spring is provided between the two sides of the slider and the end wall of the first arc groove on the corresponding side. When the storage box swings greatly relative to the balance frame, when the slider slides in the second arc groove to be ready to contact the side wall of the second arc groove on the corresponding side, it will first press the second spring between the two, and the compression of the second spring will buffer the swing of the slider, thereby buffering the swing of the storage box relative to the balance frame.
[0011] As a further improvement of the above technical solution, a plurality of first elastic bands and second elastic bands are arranged side by side inside the storage box, and the length direction of the first elastic band is perpendicular to the length direction of the second elastic band. The first elastic band and the second elastic band are interlaced to form a plurality of separate grids, which can be convenient for accommodating tools such as test tubes, and the elastic expansion and contraction of the first elastic band and the second elastic band can be convenient for fixing tools such as test tubes of different sizes, which is convenient for storing tools and pre-fixing the tools.
[0012] As a further improvement of the above technical solution, both ends of the first elastic band and the second elastic band are installed with fixing blocks, and the inner side wall of the storage box is provided with fixing grooves for the fixing blocks to be embedded in. By overcoming the elastic force of the first elastic band and the second elastic band to embed or slide the positioning blocks at both ends into the positioning grooves, it is convenient to install or remove a certain number and position of the first elastic band and the second elastic band according to actual conditions, so that the space division formed by the staggered first elastic band and the second elastic band is more reasonable, which can meet different storage needs and has high flexibility.
[0013] As a further improvement of the above technical solution, the storage box is internally installed with a first clamping plate, an elastic member, and a second clamping plate slidably arranged, and the elastic member provides an elastic force to bring the second clamping plate close to the first clamping plate. The second clamping plate can be pulled to overcome the elastic force of the elastic member, and a container such as a culture dish can be placed between the first clamping plate and the second clamping plate, and then the second clamping plate can be released, so that the container can be placed and fixed.
[0014] As a further improvement of the above technical solution, the side wall of the box body is provided with a side box, and the side box is provided with a flip cover on the side away from the box body. The flip cover can be opened from the side to facilitate taking and placing items in the side box, and the side box is high, which can easily accommodate longer tools.
[0015] As a further improvement of the above technical solution, the bottom of the side box is flush with the bottom of the box body, the bottom of the flip cover is rotatably connected to the side box, the top of the flip cover is covered with the top of the side box, and a storage cavity is provided on the side of the flip cover close to the side box. Unused container tools and the like can be placed in the storage cavity of the flip cover. When in use, the flip cover can be opened and flattened to facilitate the removal of tools in the storage cavity.

[0029] Reference Figure 3-5 The inner bottom wall of the storage compartment 11 is in the shape of a hemisphere that is concave inward, and the inner bottom wall of the storage compartment 11 is provided with a first arc groove 23, and both ends of the first arc groove 23 pass through the top of the storage compartment 11. A balance frame 21 is slidably mounted on the inner bottom wall of the storage compartment 11. An arc bar 22 is fixed to the middle bottom wall of the balance frame 21, and both the balance frame 21 and the arc bar 22 are in the shape of an arc and are adapted to the hemisphere of the inner bottom wall of the storage compartment 11. The length of the arc bar 22 is shorter than the length of the first arc groove 23, and the length of the balance frame 21 is longer than the length of the first arc groove 23. The arc strip 22 is embedded in the first arc groove 23 and can slide in the first arc groove 23. The opening of the first arc groove 23 is narrowed. The bottom wall of the balance frame 21 is embedded in the narrowed position of the opening of the first arc groove 23. The balance frame 21 is restricted by the side wall of the first arc groove 23, so that the arc strip 22 will not directly escape from the first arc groove 23.
[0030] A storage box 20 is installed above the balance frame 21. The outer bottom wall of the storage box 20 is hemispherical. Rotary holes are provided on both sides of the storage box 20. Rotary shafts are installed on the inner sides of both ends of the balance frame 21. The elasticity of the material of the balance frame 21 can be used to embed the two rotating shafts in the corresponding rotating holes, so that the storage box 20 can be rotatably installed on the balance frame 21. Bearings can be installed between the rotating shafts and the side walls of the rotating holes to improve the flexibility of rotation. At this time, the rotation center line of the storage box 20 relative to the balance frame 21 and the rotation center line of the balance frame 21 relative to the object compartment 11 are perpendicular to each other, that is, the top opening of the storage box 20 can be tilted and swung in any direction of 360 degrees relative to the object compartment 11. A counterweight is fixed to the inner bottom wall of the storage box 20 so that the mass center of gravity of the storage box 20 as a whole is at the bottom position. Containers such as test tubes with sample liquid can be placed inside the storage box 20. When the box body 10 is being transported and moved, even if it shakes or tilts, the storage box 20 can be affected by the counterweight block to keep the opening always facing upward or reduce the degree of shaking, thereby reducing overflow, leakage, and contamination of other containers caused by tilting and shaking of the sample liquid, thereby ensuring the smooth progress of sample testing.
[0031] It should be noted that when the outer cover 12 is closed on the box body 10 , there is a certain space between the inner side of the outer cover 12 and the top of the storage box 20 to allow the storage box 20 to swing relative to the box body 10 .
[0032] Mounting blocks 24 are installed at the two end positions of the first arc groove 23. The mounting blocks 24 are detachably mounted on the top of the storage compartment 11 by means of fasteners such as bolts. During installation, the mounting block 24 can be installed on one end of the first arc groove 23 first, and then the balancing frame 21 can be slid along the other end of the first arc groove 23 and embedded in the first arc groove 23. The mounting block 24 will not limit the sliding of the balancing frame 21 in the first arc groove 23, but will limit the arc bar 22 from leaving the first arc groove 23. After the balancing frame 21 is slid to the end position of the first arc groove 23 where the mounting block 24 is not installed, the mounting block 24 at this end is installed. The mounting blocks 24 at both ends of the first arc groove 23 will limit the sliding range of the arc bar 22, so that the arc bar 22 will not leave the sliding range of the first arc groove 23, thereby ensuring the stability of the rotation of the balancing frame 21 relative to the storage compartment 11.
[0033] The bottom wall of the storage box 20 is provided with a second arc groove 32, the length direction of the second arc groove 32 is perpendicular to the length direction of the first arc groove 23, a slider is installed at the middle top position of the balance frame 21, and the slider is embedded in the first arc groove 23. When the storage box 20 rotates relative to the balance frame 21, the slider slides in the second arc groove 32, and the second arc groove 32 can limit the sliding range of the slider, thereby limiting the range of rotation of the storage box 20 relative to the balance frame 21. The stability of the storage box 20 rotating relative to the storage compartment 11 is ensured.
[0034] In other embodiments, in order to prevent the box body 10 from swinging too much and causing the arc strip 22 to hit the mounting block 24, a first spring 31 is installed on the side of the mounting block 24 close to the arc strip 22. When the arc strip 22 hits the mounting block 24, it will first contact the first spring 31, and the impact of the arc strip 22 will be buffered by the compression of the first spring 31, so that the arc strip 22 cannot directly hit the mounting block 24, thereby ensuring the sliding stability of the arc strip 22 in the first arc groove 23, that is, ensuring the swing stability of the storage box 20. In other embodiments, the first spring 31 can also be installed at both ends of the arc strip 22, or the first spring 31 is at both ends of the arc strip 22 but is not fixedly connected to the arc strip 22. In other embodiments, the first spring 31 can be replaced by elastic accessories such as elastic rubber blocks or elastic sheets.
[0035] In other embodiments, in order to prevent the box body 10 from swinging too much and causing the slider 33 to hit the side wall of the second arc groove 32, a second spring 34 is installed on both sides of the slider 33. When the slider 33 hits the side wall of the second arc groove 32, it will first resist the second spring 34, and the impact of the slider 33 will be buffered by the compression of the second spring 34, so that the slider 33 cannot directly hit the side wall of the second arc groove 32, thereby ensuring the sliding stability of the slider 33 in the second arc groove 32, that is, ensuring the swing stability of the storage box 20. In other embodiments, the second spring 34 can also be installed at the end position of the second arc groove 32. In other embodiments, the second spring 34 can be replaced by an elastic accessory such as an elastic rubber block or an elastic sheet.
[0036] A plurality of first elastic bands 40 and a plurality of second elastic bands 41 are installed inside one of the storage boxes 20. The first elastic bands 40 and the second elastic bands 41 are staggered in the height direction and perpendicular to each other in the length direction. From a top view, the first elastic bands 40 and the second elastic bands 41 are staggered to form a plurality of square spaces, and different spaces can be used to place different tools. A plurality of fixing strips are arranged around the inner wall of the storage box 20, and a fixing groove 43 is provided on the side of the fixing strip away from the storage box 20. A fixing block 42 is installed at both ends of the first elastic band 40 and the second elastic band 41. The cross section of the fixing groove 43 is T-shaped. The cross section of the fixing block 42 is also T-shaped and can be embedded and slid in the fixing groove 43. Therefore, it is convenient to install or remove the first elastic band 40 and the second elastic band 41 in the storage box 20, so that the size of the space can be adjusted according to the size of the tools to be placed, which is very flexible.
[0037] A first clamping plate 50 is fixedly mounted on one side of the interior of another storage box 20, and a second clamping plate 52 is mounted on the other side of the interior of the storage box 20. A slide rail is mounted on the bottom of the storage box 20, and the bottom wall of the second clamping plate 52 is slidably mounted in the slide rail. An elastic member 51 is mounted on the side of the second clamping plate 52 away from the first clamping plate 50. The elastic member 51 is a coil spring, and one end of the coil spring away from the second clamping plate 52 is mounted on the side wall of the storage box 20, so that the elastic force of the coil spring pushes the second clamping plate 52 to fit with the first clamping plate 50. When it is necessary to place tools such as culture dishes, the second clamping plate 52 can be opened to overcome the elastic force of the coil spring, and the culture dish can be placed between the first clamping plate 50 and the second clamping plate 52. The culture dish is clamped between the first clamping plate 50 and the second clamping plate 52 by the elastic force of the coil spring, so that the culture dish can be firmly placed in the storage box 20. In other embodiments, the elastic member 51 may be an elastic rope, the two ends of which are fixed on both sides of the first clamping plate 50, and the middle part of the elastic rope is sleeved outside the second clamping plate 52, so that the elastic force of the elastic rope can pull the second clamping plate 52 close to the first clamping plate 50, thereby clamping the tool between the first clamping plate 50 and the second clamping plate 52.
[0038] In other embodiments, the two storage compartments 11 on the box body 10 can use the same storage box 20 with an internal fixed structure. If the box body 10 is provided with only one storage compartment 11, one of the two storage boxes 20 with different internal fixed structures can be selected according to the needs.
[0039] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
