Description

Skin sample collection and storage device

Technical Field

The invention relates to the technical field of storage containers, and in particular to a skin sample collection and storage device.

Background technique

Dermatology mainly treats various skin diseases. In order to facilitate the diagnosis of the cause of the disease, it is usually necessary to take samples from the patient's affected skin for testing. In this process, a storage device is needed to store the samples. For example, a skin sample storage device for dermatology disclosed in publication number CN214608898U, through the coordinated use of a sealing cover and a sealing dish as well as a movable column and a limit spring, enables the skin sample storage device for dermatology to place the sample inside the storage base, and then press the sealing cover to make the snap-on plate snap into the snap-on groove outside the sealing dish, thereby sealing the sample between the storage base and the sealing ring, and then place the sealing dish inside the limit base, and close the cover. After the cover is closed, the movable column contacts the sealing cover and squeezes the sealing cover under the action of the elastic force of the limit spring, thereby assisting in fixing the sealing cover.

Although the above-mentioned device seals and isolates the samples by providing a sealing cover and a sealing dish that cooperate with each other, in actual use, when multiple samples need to be tested, due to the limited internal space of the storage box and the obstruction at the edge of the storage box, in order to facilitate the access to the samples in the sealing dish, the test personnel need to take out the covered sealing cover and the sealing dish from the storage box one by one, and release the two clamping plates that are engaged with the sealing dish, thereby realizing the separation operation of the sealing dish and the sealing cover. During this operation, in order to increase the speed at which the two clamping plates are disengaged from the sealing dish, both hands are generally used for operation, and the clamping plates can only be opened after the fingertips are aligned with the ends of the clamping plates, which increases the difficulty of separating the sealing cover and the sealing dish, and is not conducive to the rapid access of the test samples by the test personnel. Therefore, the present application provides a skin sample collection and storage device to meet the needs.

Summary of the invention

The technical problem to be solved by the present invention is to provide a skin sample collection and storage device to solve the problem that the sealing cover and the sealing dish used in the existing skin sample collection and storage device are difficult to separate, which is not conducive to the rapid use of the test sample by the test personnel.

Compared with the prior art, the present invention has at least the following beneficial effects:

In the above scheme, by setting a limit platform, a sleeve box, a first locking component and a limit component, when sampling and testing are required, the upper cover is removed from the bottom plate, and under the limiting action of the limit component and the card slot, the pull ring can be directly pulled to disengage the card block from the convex edge on the bottom box body, and then the upper box body connected to the bottom box body is opened and rotated. At this time, the sample placed in the bottom box body can be directly taken, which reduces the difficulty of opening the upper box body, so that the upper box body can be opened with one hand, which is convenient for the test personnel to quickly take the test sample.

By providing a bottom plate, the flat plate structure of the bottom plate reduces the space limitation of the position where the sleeve is placed above the bottom plate after the upper cover is separated from the bottom plate, so as to improve the convenience of taking and placing the sleeve and pulling the pull ring.

By setting up a slide, when it is necessary to place a sample in the bottom box body, the sample can be placed on the slide. The advantage of such a setting is that when taking the sample, after opening the upper box body, the two sides of the slide can be directly pinched from the notch to take out the slide with the sample. When it is necessary to separate the sample from the slide, the sample and the slide can be directly scraped off from the slide. The operation is simple and convenient, which further improves the convenience of taking the sample.

By providing a limiting sleeve, when the upper box body is closed, the limiting sleeve on the upper box body will gradually approach the slide and finally interfere with the slide. At the same time, the bottom of the limiting sleeve interferes with the slide to limit the sample placed on the slide, thereby preventing the sample placed on the slide from moving out of the mark or even separating from the slide during the movement of the bottom box body and the upper box body, which will affect the stability of sample storage and the convenience of access.

The first spring sheet is provided to elastically support the specimen slide placed on the U-shaped plate, so that when the limiting sleeve squeezes the specimen slide, the specimen slide moves downward and squeezes the first spring sheet to cause the first spring sheet to produce elastic deformation, thereby preventing the specimen slide from being deformed due to the pressure of the U-shaped plate and the limiting sleeve when the limiting sleeve contacts the specimen slide, thereby affecting the normal use of the specimen slide. At the same time, the elastic force of the first spring sheet ensures the tightness of the fit between the specimen slide and the limiting sleeve, thereby further improving the limiting effect of the sample placed on the specimen slide.

By eccentrically setting the mark on the slide and staggeredly setting the notch with respect to the mark, the opening width of the notch can be designed to be larger, thereby improving the convenience of pinching and removing the slide from this position, and at the same time avoiding the chance of hand contact with the sample on the slide during the process of removing the slide, thereby avoiding contamination of the sample and affecting sample detection.

By providing a balancing pressure block, when the limiting sleeve presses down the specimen slide, the first elastic sheet at the bottom is not evenly pressed due to local force on the specimen slide, which causes deflection and affects the tightness of the contact position between the limiting sleeve and the specimen slide.

By providing a sample separation component, during the process of opening the upper box body, the movable cover can be pressed multiple times by fingers. During the pressing process, the movable cover slides along the inner wall of the limiting sleeve and scrapes off the sample stuck to the inner wall of the limiting sleeve. The scraped sample falls onto the slide under the action of gravity and inertia, thereby reducing the loss when taking the sample and improving the sample utilization rate. It should be noted that this operation should be performed when the opening and closing angle of the upper box body and the bottom box body is less than thirty degrees, to avoid the sample adhered to the limiting sleeve being thrown outside the mark or even outside the slide due to the action of inertia due to the opening angle of the upper box body being too large, thereby increasing the loss when taking the sample.

By setting the sliding rod and the second spring sheet, after the movable cover is pressed, the second spring sheet is subjected to force to produce elastic deformation. When the finger is suddenly separated from the movable cover by sliding, the movable cover is quickly reset under the elastic force of multiple second spring sheets, and the sliding rod is driven to hit the top of the sliding groove under the action of inertia. The vibration generated by the impact will shake off part of the sample adhering to the movable cover during the scraping process of the limiting sleeve, further reducing the loss caused by sample taking. The structure is simple and easy to use. At the same time, the movement stroke of the movable cover can also be limited by setting the sliding groove and the sliding rod to prevent the movable cover from detaching from the upper box body or falling into the movable cover. The structure is simple to assemble and has low manufacturing cost.

By providing a protrusion on the top of the paddle, the closed bottom plate and the upper cover will be tilted when they are inverted on the workbench, so as to intuitively remind the inspector that the device is inverted, so that the inspector can right the device in time to avoid the device being inverted on the workbench for a long time, causing the sample on the slide to fall into the limiting sleeve and the movable cover under the action of gravity, affecting the convenience of sample retrieval.

As shown in Fig. 1 to Fig. 3 and Fig. 7, an embodiment of the present invention provides a skin sample collection and storage device, comprising a bottom plate 1 and an upper cover 2 that are covered together, wherein at least one sleeve 4 for individually sealing and storing samples is arranged in a closed space formed by the bottom plate 1 and the upper cover 2, and a limiting platform 3 for separating and limiting a plurality of sleeves 4 is arranged on the bottom plate 1; the sleeve 4 comprises a bottom box body 5 and an upper box body 6 that are rotatably connected, and a convex edge 7 is arranged on the side of the bottom box body 5 and the upper box body 6 that are close to each other, and a flange 7 is arranged on the upper box body 6 to hold the bottom box body 5 and the upper box body 6 by snapping with the convex edge 7 on the bottom box body 5. The first locking component 8 covered by the upper box body 6; the first locking component 8 includes a clamping block 11 fixedly connected to the upper box body 6 at a position away from the rotational connection with the bottom box body 5, the clamping block 11 is clamped with the convex edge 7 on the bottom box body 5, and a pull ring 12 arranged upwardly and inclined is fixedly connected to the clamping block 11; the limiting platform 3 includes a platform body 28 fixedly connected to the bottom plate 1, and at least one limiting groove 29 for limiting the upper box body 6 is provided on the platform body 28, and limiting components 9 are provided on opposite sides of the upper box body 6, and clamping grooves 33 for the limiting components 9 are provided on opposite sides of the limiting groove 29.

By setting the limiting platform 3, the sleeve box 4, the first locking component 8 and the limiting component 9, when sampling and testing are required, the upper cover 2 is removed from the bottom plate 1, and under the limiting action of the limiting component 9 and the card slot 33, the pull ring 12 can be directly pulled to disengage the card block 11 from the convex edge 7 on the bottom box body 5, and then the upper box body 6 rotatably connected to the bottom box body 5 is opened, and the sample placed in the bottom box body 5 can be directly taken out, which reduces the difficulty of opening the upper box body 6, so that the upper box body 6 can be opened by one hand, which is convenient for the test personnel to quickly take the test sample.

By providing the bottom plate 1 and the flat plate structure of the bottom plate 1 , the space limitation of the position where the sleeve 4 is placed above the bottom plate 1 after the upper cover 2 is separated from the bottom plate 1 is reduced, so as to improve the convenience of taking and placing the sleeve 4 and pulling the pull ring 12 .

As shown in Figures 3 and 4, a specimen slide 15 for carrying samples is placed in the bottom box body 5, and a U-shaped plate 13 for limiting the specimen slide 15 is fixedly connected to the bottom box body 5. Both ends of the U-shaped plate 13 are provided with guiding inclined plates 14, and the guiding inclined plates 14 are away from each other at one end of the U-shaped plate 13. By providing the guiding inclined plates 14, when the specimen slide 15 is placed on the U-shaped plate 13, the specimen slide 15 can be guided by the guiding inclined plates 14 to improve the convenience of placing the specimen slide 15. A mark 16 for marking the sample placement area is provided on the specimen slide 15, and the mark 16 can be a plurality of dots or a circle. A limiting sleeve 20 for limiting the sample placed on the mark 16 is fixedly connected to the upper box body 6, and mutually symmetrical notches 17 are provided on the U-shaped plate 13.

By providing the specimen slide 15, when it is necessary to place a sample in the bottom box body 5, the sample can be placed on the specimen slide 15. The advantage of such a configuration is that when taking the sample, after opening the upper box body 6, the two sides of the specimen slide 15 can be directly pinched from the position of the notch 17 to take out the specimen slide 15 carrying the sample. When it is necessary to separate the sample on the specimen slide 15 from the specimen slide 15, the sample and the specimen slide 15 can be directly scraped off from the specimen slide 15. The operation is simple and convenient, which further improves the convenience of taking the sample.

By providing the limiting sleeve 20, when the upper box body 6 is closed, the limiting sleeve 20 on the upper box body 6 will gradually approach the specimen slide 15 and finally collide with the specimen slide 15. At the same time, the bottom of the limiting sleeve 20 will collide with the specimen slide 15 to limit the sample placed on the specimen slide 15, thereby preventing the sample placed on the specimen slide 15 from moving outside the mark 16 or even separating from the specimen slide 15 during the movement of the bottom box body 5 and the upper box body 6, thereby affecting the stability of sample storage and the convenience of access.

As shown in Figures 3 and 4, the mark 16 is eccentrically arranged on the slide 15, the notch 17 is staggered with the position of the mark 16, and at least one first through groove 18 is opened on the U-shaped plate 13. A first spring piece 19 for elastically supporting the slide 15 is fixedly connected in the first through groove 18. The first through groove 18 and the first spring piece 19 are integrally formed with a simple structure and low manufacturing cost.

By providing the first spring piece 19, elastic support is provided for the specimen slide 15 placed on the U-shaped plate 13, so that when the limiting sleeve 20 squeezes the specimen slide 15, the specimen slide 15 moves downward and squeezes the first spring piece 19 to cause the first spring piece 19 to produce elastic deformation, thereby preventing the specimen slide 15 from being deformed due to the pressure of the U-shaped plate 13 and the limiting sleeve 20 when the limiting sleeve 20 conflicts with the specimen slide 15, thereby affecting the normal use of the specimen slide 15. At the same time, the elastic force of the first spring piece 19 ensures the tightness of the fit between the specimen slide 15 and the limiting sleeve 20, thereby further improving the limiting effect of the sample placed on the specimen slide 15.

By eccentrically setting the mark 16 on the slide 15 and staggering the notch 17 with respect to the mark 16, the opening width of the notch 17 can be designed to be larger, thereby improving the convenience of pinching and removing the slide 15 from this position, and at the same time avoiding the probability of the hand contacting the sample on the slide 15 during the process of removing the slide 15, thereby avoiding contamination of the sample and affecting the sample detection.

As shown in Figure 3, a balancing pressure block 21 for balancing the pressure of the limiting sleeve 20 on the specimen slide 15 is fixedly connected to the upper box body 6. The balancing pressure block 21 can be connected to the limiting sleeve 20. The advantage of such a setting is that when the limiting sleeve 20 presses down on the specimen slide 15, the specimen slide 15 is prevented from being unevenly pressed on the first spring piece 19 at the bottom due to local force, thereby causing deflection, affecting the tightness of the limiting sleeve 20 and the specimen slide 15 at the contact position.

As shown in Figures 3 to 5, the upper box body 6 is equipped with a sample separation component 10 for scraping off samples adhered to the inner wall of the limiting sleeve 20 during the opening process of the upper box body 6; both ends of the limiting sleeve 20 are through-connected, and the sample separation component 10 includes a movable cover 24 slidably sleeved in the limiting sleeve 20, a groove 22 is provided at one end of the upper box body 6 away from the bottom box body 5, and slide grooves 23 are provided on opposite sides of the groove 22. The movable cover 24 is located in the groove 22, and a sliding rod 25 slidably connected to the slide groove 23 is fixedly connected to the movable cover 24. A plurality of second elastic sheets 26 are fixedly connected to the movable cover 24, and one end of the second elastic sheet 26 away from the movable cover 24 contacts with the bottom of the groove 22. The sample adhered to the inner wall of the limiting sleeve 20 can be scraped off by sliding the movable cover 24.

By setting the sample separation component 10, during the process of opening the upper box body 6, the movable cover 24 can be pressed multiple times by fingers. During the pressing process, the movable cover 24 slides along the inner wall of the limiting sleeve 20 and scrapes off the sample adhering to the inner wall of the limiting sleeve 20. The scraped sample falls onto the slide 15 under the action of gravity and inertia, thereby reducing the loss when the sample is taken and improving the sample utilization rate. It should be noted that this operation should be performed when the opening and closing angle of the upper box body 6 and the bottom box body 5 is less than thirty degrees, so as to avoid the sample adhering to the limiting sleeve 20 being thrown out of the mark 16 or even out of the slide 15 due to the action of inertia due to the opening angle of the upper box body 6 being too large, thereby increasing the loss when the sample is taken.

By setting the slide bar 25 and the second elastic sheet 26, after the movable cover 24 is pressed, the second elastic sheet 26 is subjected to force to produce elastic deformation. When the finger is separated from the movable cover 24 by sliding, the movable cover 24 is quickly reset under the elastic force of multiple second elastic sheets 26, and the slide bar 25 is driven to hit the top of the slide groove 23 under the action of inertia. The vibration generated by the impact will shake off part of the sample adhering to the movable cover 24 during the scraping process of the limiting sleeve 20, further reducing the loss caused by sample taking, and the structure is simple and easy to use. At the same time, by setting the slide groove 23 and the slide bar 25, the movement stroke of the movable cover 24 can also be limited to prevent the movable cover 24 from being separated from the upper box body 6 or falling into the movable cover 24, and the structure is simple to assemble and has low manufacturing cost.

In this embodiment, the top of the upper box body 6 is in contact with the top inner wall of the upper cover 2. The advantage of this arrangement is that when the upper cover 2 is covered with the bottom plate 1, the closure of the upper box body 6 and the bottom box body 5 can be effectively guaranteed by the conflict with the upper box body 6. The structure is simple and easy to use. The movable cover 24 and the convex edge 7 of the bottom box body 5 are fixedly connected with a sealing ring 27. The sealing ring 27 is provided to ensure the sealing of the connection position between the movable cover 24 and the limiting sleeve 20 and the connection position between the bottom box body 5 and the upper box body 6.

As shown in Figures 3, 6 and 7, the limiting component 9 includes a first limiting block 30 fixedly connected to one side of the upper box body 6. The stability of the first limiting block 30 and the card slot 33 can be improved by setting an anti-slip structure on the first limiting block 30. The first limiting block 30 is provided with a first guide bevel 31 and a rounded corner 32, and a slot 34 connected to the card slot 33 is provided on one side of the limiting slot 29, and a third guide bevel 39 is provided on the side of the slot 34 away from the card slot 33.

By setting the limiting component 9, the card slot 33 and the third guiding slope 39, the specific steps of placing the sampling set 4 into the limiting slot 29 are as follows: placing the bottom box body 5 into the limiting slot 29, and allowing the first limiting blocks 30 on both sides of the bottom box body 5 to enter the limiting slot 29 through the slots 34; when the bottom of the bottom box body 5 is completely fitted with the bottom of the limiting slot 29, slide the upper box body 6 to one side so that the first limiting block 30 is completely inserted into the card slot 33. The structure is simple and the installation is convenient.

The third guiding bevel 39 is provided to guide the first limit block 30 that is about to enter the slot 34, the rounded corner 32 is used to further improve the guiding effect at the contact position between the first limit block 30 and the slot 34, and the first guiding bevel 31 is provided to guide the contact position between the first limit block 30 and the solid part above the slot 33, thereby further improving the convenience of the engagement operation between the first limit block 30 and the slot 33.

As shown in Figures 1 and 2, 7 and 8, the upper cover 2 is provided with a bayonet 37 on opposite sides, and the bottom plate 1 is provided with a second locking component 40 for cooperating with the bayonet 37 to limit the upper cover 2 on the bottom plate 1; the second locking component 40 includes a paddle 35 fixedly connected to the opposite sides of the bottom plate 1, and the opposite sides of the two paddles 35 are fixedly connected with a second limiting block 36, and the top of the second limiting block 36 is provided with a second guiding slope 38, the top of the paddle 35 exceeds the top of the upper cover 2, and the top of the paddle 35 is provided with a protrusion.

By setting the second locking component 40, when it is necessary to cover the upper cover 2 on the bottom plate 1, the upper cover 2 can be placed parallel to the bottom plate 1, and the bayonet 37 is aligned with the second limit block 36 and then the upper cover 2 is pressed down until the second limit block 36 is engaged with the sealing ring 27, so that the closing operation of the bottom plate 1 and the upper cover 2 can be completed. The structure is simple and easy to use. The second guiding slope 38 provided on the second limit block 36 is used to guide the edge position of the upper cover 2 during the pressing process to avoid the edge of the upper cover 2 from contacting the second limit block 36 and affecting the smoothness of the engagement operation between the second limit block 36 and the bayonet 37.

By providing a protrusion on the top of the paddle 35, the closed bottom plate 1 and the upper cover 2 will be tilted when they are inverted on the workbench, so as to intuitively remind the inspector that the device is inverted, so that the inspector can right the device in time to avoid the device being inverted on the workbench for a long time, causing the sample on the slide 15 to fall into the limiting sleeve 20 and the movable cover 24 under the action of gravity, affecting the convenience of sample retrieval.

The technical solution provided by the present invention, by setting a limit platform, a sleeve box, a first locking component, and a limit component, when sampling and testing are required, the upper cover is removed from the bottom plate, and under the limiting action of the limit component and the card slot, the pull ring can be directly pulled to disengage the card block from the convex edge on the bottom box body, and then the upper box body rotatably connected to the bottom box body is opened, and the sample placed in the bottom box body can be directly taken out, which reduces the difficulty of opening the upper box body, so that the upper box body can be opened with one hand, which is convenient for the test personnel to quickly take the test sample.

By providing a bottom plate, the flat plate structure of the bottom plate reduces the space limitation of the position where the sleeve is placed above the bottom plate after the upper cover is separated from the bottom plate, so as to improve the convenience of taking and placing the sleeve and pulling the pull ring.

By setting up a slide, when it is necessary to place a sample in the bottom box body, the sample can be placed on the slide. The advantage of such a setting is that when taking the sample, after opening the upper box body, the two sides of the slide can be directly pinched from the notch to take out the slide with the sample. When it is necessary to separate the sample from the slide, the sample and the slide can be directly scraped off from the slide. The operation is simple and convenient, which further improves the convenience of taking the sample.

By providing a limiting sleeve, when the upper box body is closed, the limiting sleeve on the upper box body will gradually approach the slide and finally interfere with the slide. At the same time, the bottom of the limiting sleeve interferes with the slide to limit the sample placed on the slide, thereby preventing the sample placed on the slide from moving out of the mark or even separating from the slide during the movement of the bottom box body and the upper box body, which will affect the stability of sample storage and the convenience of access.

The first spring sheet is provided to elastically support the specimen slide placed on the U-shaped plate, so that when the limiting sleeve squeezes the specimen slide, the specimen slide moves downward and squeezes the first spring sheet to cause the first spring sheet to produce elastic deformation, thereby preventing the specimen slide from being deformed due to the pressure of the U-shaped plate and the limiting sleeve when the limiting sleeve contacts the specimen slide, thereby affecting the normal use of the specimen slide. At the same time, the elastic force of the first spring sheet ensures the tightness of the fit between the specimen slide and the limiting sleeve, thereby further improving the limiting effect of the sample placed on the specimen slide.

By eccentrically setting the mark on the slide and staggeredly setting the notch with respect to the mark, the opening width of the notch can be designed to be larger, thereby improving the convenience of pinching and removing the slide from this position, and at the same time avoiding the chance of hand contact with the sample on the slide during the process of removing the slide, thereby avoiding contamination of the sample and affecting sample detection.

By providing a balancing pressure block, when the limiting sleeve presses down the specimen slide, the first elastic sheet at the bottom is not evenly pressed due to local force on the specimen slide, which causes deflection and affects the tightness of the contact position between the limiting sleeve and the specimen slide.

By providing a sample separation component, during the process of opening the upper box body, the movable cover can be pressed multiple times by fingers. During the pressing process, the movable cover slides along the inner wall of the limiting sleeve and scrapes off the sample stuck to the inner wall of the limiting sleeve. The scraped sample falls onto the slide under the action of gravity and inertia, thereby reducing the loss when taking the sample and improving the sample utilization rate. It should be noted that this operation should be performed when the opening and closing angle of the upper box body and the bottom box body is less than thirty degrees, to avoid the sample adhered to the limiting sleeve being thrown outside the mark or even outside the slide due to the action of inertia due to the opening angle of the upper box body being too large, thereby increasing the loss when taking the sample.

By setting the sliding rod and the second spring sheet, after the movable cover is pressed, the second spring sheet is subjected to force to produce elastic deformation. When the finger is suddenly separated from the movable cover by sliding, the movable cover is quickly reset under the elastic force of multiple second spring sheets, and the sliding rod is driven to hit the top of the sliding groove under the action of inertia. The vibration generated by the impact will shake off part of the sample adhering to the movable cover during the scraping process of the limiting sleeve, further reducing the loss caused by sample taking. The structure is simple and easy to use. At the same time, the movement stroke of the movable cover can also be limited by setting the sliding groove and the sliding rod to prevent the movable cover from detaching from the upper box body or falling into the movable cover. The structure is simple to assemble and has low manufacturing cost.

By setting a limiting component, a card slot and a third guiding slope, the specific steps for placing the completed sampling box into the limiting slot are as follows: place the bottom box body into the limiting slot, and allow the first limiting blocks on both sides of the bottom box body to enter the limiting slot through the slots; when the bottom of the bottom box body is completely fitted with the bottom of the limiting slot, slide the upper box body to one side so that the first limiting block is completely inserted into the card slot; the structure is simple and the installation is convenient.

By setting a third guiding bevel to guide the first limit block that is about to enter the slot, the guiding effect at the contact position between the first limit block and the slot is further improved by rounding the corners, and by providing a first guiding bevel to guide the contact position between the first limit block and the solid part above the slot, the convenience of the card connection operation between the first limit block and the slot is further improved.

By setting the second locking component, when it is necessary to close the upper cover on the bottom plate, the upper cover can be placed parallel to the bottom plate, and the upper cover can be pressed down after the bayonet is aligned with the second limit block until the second limit block is engaged with the sealing ring, and the closing operation of the bottom plate and the upper cover can be completed. The structure is simple and easy to use. The edge position of the upper cover during the pressing process is guided by the second guiding bevel provided on the second limit block, so as to avoid the edge of the upper cover from contacting with the second limit block, which affects the smoothness of the engagement operation between the second limit block and the bayonet.

By providing a protrusion on the top of the paddle, the closed bottom plate and the upper cover will be tilted when they are inverted on the workbench, so as to intuitively remind the inspector that the device is inverted, so that the inspector can right the device in time to avoid the device being inverted on the workbench for a long time, causing the sample on the slide to fall into the limiting sleeve and the movable cover under the action of gravity, affecting the convenience of sample retrieval.
