Description

Technical Field

[0001] The invention relates to a chemical testing and sampling device, in particular to a chemical testing and sampling device with an isolation and protection structure applied in the field of chemical testing and sampling. Background Art

[0002] Clinical blood tests can be divided into general blood tests, laboratory tests for hemolytic anemia, bone marrow cytology tests, blood typing and cross-matching tests, which can detect the hematological characteristics of common blood diseases. When conducting blood tests, blood samples are usually stored in blood collection tubes, which are generally inserted into test tube racks. The surface of the blood collection tubes is not effectively isolated, resulting in air with pathogens outside the blood collection tubes easily diffusing into the blood collection tubes, causing the blood sample in the blood collection tube to be contaminated, affecting the results of blood tests.

[0003] The specification of Chinese invention patent CN202210784418.0 discloses a sampling device for blood diseases with isolation protection, including a storage bottle, a storage groove is provided on the upper surface of the storage bottle, a bottle cap is provided on the upper part of the storage bottle, a mounting groove A is provided on the lower surface of the bottle cap, a hook is fixedly installed on the upper surface of the bottle cap, and a sealing component is provided inside the storage bottle. In this invention, by setting a sealing component, the inclined surface of the mounting groove A can be pressed to slide the clamping column to the inside of the mounting groove B by pressing the bottle cap downward. When the storage bottle fits tightly with the sealing gasket and the clamping column is aligned with the clamping groove, the elastic force of the spring pushes the clamping column to snap into the clamping groove to fix the storage bottle and the bottle cap, thereby realizing the separate isolation and placement of the blood specimen tube. By setting a clamping component, the blood specimen tube can be clamped by pressing the bottle cap downward, thereby effectively protecting it.

[0004] The isolation protection structure outside the existing laboratory sampling device uses an extrusion device to achieve the sealing of the blood collection tube, but it is difficult to achieve when the isolation protection equipment outside the blood collection tube is subsequently disassembled. Therefore, when taking samples for laboratory testing, it is necessary to cause certain damage to the blood collection tube and the isolation protection equipment before sampling can be successfully carried out. This is not conducive to the reuse of the isolation protection equipment, and it will also cause certain contamination to the blood sample, affecting the test results. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is to provide a reusable isolation and protection device, so that the laboratory sampling equipment can not only perform isolation and protection processing when preserving samples, but also reduce the preservation cost. In addition, it can simplify the operating steps of separating the two and avoid sample contamination caused by violent destruction.

[0006] In order to solve the above problems, the present invention provides a laboratory sampling device with an isolation and protection structure, comprising a specimen tube, an isolation cover is sleeved on the top of the specimen tube, a plurality of strip grooves are arranged inside the isolation cover, a plurality of cross bars are equidistantly installed on the inner wall of the strip groove, and one end of the cross bar is rotated to penetrate the inner wall of the isolation cover, one end of the cross bar is connected to an abutment block, and the plurality of abutment blocks are arranged in a downward fish scale shape in an initial state, the other end of the top cross bar is connected to the inner wall of the strip groove through a reset shaft, a gear is sleeved on the surface of each cross bar, two adjacent gears in the vertical direction are meshed with each other, the other end of the bottom cross bar penetrates to the outside of the isolation cover and is fixedly connected with a rotating plug, a limiting hole is arranged through the inside of the rotating plug, and a limiting plug rod is inserted into the inside of the limiting hole, and a plug hole arranged corresponding to the limiting hole is arranged on the surface of the isolation cover at a position corresponding to the rotating plug, and the plug hole is engaged with the limiting plug rod;

[0007] A protective sticker is connected to the top of the isolation cover.

[0008] In the above-mentioned laboratory sampling device with an isolation and protection structure, the abutment blocks form a fish-scale layout, which can effectively prevent the isolation cover from being pulled off the surface of the specimen tube. The isolation cover can also be easily and labor-savingly removed from the surface of the specimen tube by releasing the limit rod and the reset shaft, thereby reducing blood sample contamination caused by violent disassembly, and making the isolation cover reusable to reduce costs.

[0009] As a further improvement of the present application, a threaded cover is provided on the top of the specimen tube, and a rubber plug is provided through the top of the threaded cover, the center of the rubber plug and the center of the protective patch are on the same axis, and the diameter of the rubber plug is smaller than the diameter of the protective patch.

[0010] As a further improvement of the present application, the protective patch has a medical adhesive layer and a sterile rubber pad, wherein the sterile rubber pad is bonded to the top wall of the isolation cover through the medical adhesive layer, and the sterile rubber pad is a disposable consumable.

[0011] As a further improvement of the present application, the distance between the top of the uppermost abutment block and the top wall of the isolation cover is greater than the length of the abutment block, and the abutment block is made of a rigid material.

[0012] As a further improvement of the present application, in the initial state, the bottom end of the abutment block abuts against the surface of the threaded cover at the top of the specimen tube, and the height of the isolation cover is not less than the height of the threaded cover.

[0013] As a further improvement of the present application, in the initial state, the limit rod is inserted into the limit hole and the insertion hole, and when the isolation cover and the threaded cover are separated, the limit rod is disengaged from the limit hole.

[0014] As another improvement of the present application, the interior of the isolation cover is slidably inserted with a sliding rod corresponding to the rotating plug one by one, and the tail end of the sliding rod is connected to a wedge block symmetrically arranged about the cross bar through a connecting plate, and the tail end of the uppermost cross bar is connected to a linkage disk with a diameter larger than the diameter of the cross bar, and an elastic strip is connected at the center position of the linkage disk, and the tail end of the elastic strip is connected to the inner wall of the strip groove, and cover rings are installed on both side surfaces of the gears located in even positions in the vertical direction, and the outer diameter of the cover ring is larger than the diameter of the gear.

[0015] As another improved supplement of the present application, in the initial state, the lower half of the wedge block fits with the surface of the linkage disk, and the elastic strip is located in the middle of the two wedge blocks. In the initial state, the elastic strip is in a stretched state.

[0016] As another improved supplement of the present application, the surface of the sliding rod is coated with a magnetic attraction layer, and the inner wall of the channel provided on the inner wall of the isolation cover and matching the sliding rod is arranged with a magnetic layer that attracts the magnetic attraction layer.

[0017] To summarize, the laboratory sampling device includes a specimen tube and an isolation cover, wherein abutment blocks and cross bars are arranged inside the isolation cover, and the abutment blocks form a fish-scale layout, which can effectively prevent the isolation cover from being pulled off the surface of the specimen tube. The abutment blocks originally arranged in a downward fish-scale pattern can be switched to an upward fish-scale pattern by releasing the cooperation of the limit plug rod and the reset shaft, so that the isolation cover can be pulled upward to leave the surface of the specimen tube easily and labor-savingly, thereby reducing the contamination of blood samples caused by violent disassembly. The storage cost can also be reduced by virtue of the reusable isolation cover, and the isolation protection operation of specimen tubes of different thicknesses can be adapted to through the cooperation of the slide rod, the cover ring, the wedge block and the elastic strip.

[0032] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0033] The first implementation method:

[0034] Figure 1-5A laboratory sampling device with an isolation protection structure is shown, comprising a specimen tube 1, an isolation cover 2 is sleeved on the top of the specimen tube 1, a plurality of strip grooves are arranged inside the isolation cover 2, a plurality of cross bars 7 are equidistantly installed on the inner wall of the strip groove, and one end of the cross bar 7 rotates to penetrate the inner wall of the isolation cover 2, an abutment block 5 is connected to one end of the cross bar 7, and the plurality of abutment blocks 5 are arranged in a downward fish scale shape in an initial state, the other end of the top cross bar 7 is connected to the inner wall of the strip groove through a reset shaft, a gear 6 is sleeved on the surface of each cross bar 7, two adjacent gears 6 in the vertical direction are meshed with each other, and the bottom cross bar 7 is connected to the inner wall of the strip groove through a reset shaft, and the gears 6 are sleeved on the surface of each cross bar 7. The gears 6 adjacent to each other in the vertical direction are meshed with each other, and the bottom cross bar 7 is connected to the inner wall of the strip groove through a reset shaft. The other end of the crossbar 7 passes through the outside of the isolation cover 2 and is fixedly connected to the rotating plug 3. The interior of the rotating plug 3 is provided with a limiting hole 32 that passes through it, and the limiting plug rod 31 is inserted into the limiting hole 32. The surface of the isolation cover 2 is provided with a plug hole that is arranged corresponding to the limiting hole 32 at a position corresponding to the rotating plug 3, and the plug hole is engaged with the limiting plug rod 31; the top of the isolation cover 2 is connected to a protective sticker 4, the top of the specimen tube 1 is provided with a threaded cover, and the top of the threaded cover is penetrated by a rubber plug, the center of the rubber plug and the center of the protective sticker 4 are on the same axis, and the diameter of the rubber plug is smaller than the diameter of the protective sticker 4;

[0035] In the initial state, the bottom end of the abutment block 5 abuts against the surface of the threaded cover at the top of the specimen tube 1 , and the height of the isolation cover 2 is not less than the height of the threaded cover.

[0036] In the initial state, the limiting plug rod 31 is inserted into the limiting hole 32 and the insertion hole. When the isolation cover 2 and the threaded cover are separated, the limiting plug rod 31 is separated from the limiting hole 32.

[0037] Specifically, when providing isolation protection for the specimen tube 1, blood needs to be drawn first. After the blood collection is completed, the tube body with the needle is pulled out of the rubber stopper, and then the isolation cover 2 is covered on the surface of the threaded cover. Since the abutment blocks 5 are stacked in a fish scale-like arrangement and the tail end of the abutment blocks 5 is in close contact with the surface of the threaded cover, during the subsequent isolation cover 2 providing isolation protection for the specimen tube 1, if the isolation cover 2 has a tendency to detach from the specimen tube 1, the limiting plug 31 is inserted into the limiting hole 32 and the plug hole, which has a restraining effect on the rotating plug 3, preventing the rotating plug 3 from rotating and driving the bottom cross bar 7 to rotate, thereby making the multiple abutment blocks 5 in the isolation cover 2 all in a downwardly stacked state, which has an abutment effect on the isolation cover 2 in the upwardly detached state, preventing the isolation cover 2 from detaching upward, so that the isolation cover 2 can maintain a stable isolation and protection effect with the threaded cover and the specimen tube 1;

[0038] In addition, when it is necessary to separate the isolation cover 2 and the threaded cover, the limiting plug 31 needs to be pulled out of the inside of the rotating plug 3. At this time, under the action of the reset shaft, the top cross bar 7 is reset and rotated, and under the meshing action of the gear 6, the cross bar 7 below is driven to rotate, so that the abutment block 5 originally stacked downward is rotated to form an upward stacked state, which is convenient for the isolation cover 2 to be separated from the threaded cover upward, and then the protective sticker 4 is torn off and removed, and a new protective sticker 4 is re-glued to realize a new round of use, and then the threaded cover is removed, and the sample in the specimen tube 1 is sucked by the dropper (such as Figure 6-7 shown);

[0039] After a round of isolation and protection work is completed, the rotating plug 3 is rotated to drive the lowest cross bar 7 to rotate, so that the abutment blocks 5 stacked upwards can be rotated downward, and under the meshing action of the gear 6, the multiple abutment blocks 5 are driven to return to the downward state, and the limiting rod 31 is inserted into the limiting hole 32 and the socket to limit the rotating plug 3.

[0040] The protective patch 4 has a medical adhesive layer 41 and a sterile rubber pad 42 , wherein the sterile rubber pad 42 is bonded to the top wall of the isolation cover 2 through the medical adhesive layer 41 , and the sterile rubber pad 42 is a disposable consumable.

[0041] Specifically, after the isolation cover 2 is covered on the surface of the threaded cover, the protective sticker 4 can cover the rubber plug in the threaded cover, cover and isolate the insertion gap in the rubber plug during sampling, and replace it after completing a single isolation and protection work, so that the isolation cover 2 can be reused.

[0042] The distance between the top of the uppermost abutment block 5 and the top wall of the isolation cover 2 is greater than the length of the abutment block 5 , and the abutment block 5 is made of a rigid material.

[0043] Specifically, the gap between the uppermost abutting block 5 and the isolation cover 2 ensures that the uppermost abutting block 5 can rotate normally without being blocked by the top wall of the isolation cover 2 during rotation.

[0044] The second implementation method:

[0045] Figure 9-11 It is shown that the interior of the isolation cover 2 is slidably inserted with a sliding rod 8 corresponding to the rotating plug 3 one by one, and the tail end of the sliding rod 8 is connected to a wedge block 10 symmetrically arranged about the cross bar 7 through a connecting plate, and the tail end of the uppermost cross bar 7 is connected to a linkage disk 11 with a diameter larger than the diameter of the cross bar 7, and an elastic strip 12 is connected at the center position of the linkage disk 11, and the tail end of the elastic strip 12 is connected to the inner wall of the strip groove, and cover rings 9 are installed on both side surfaces of the gears 6 located in even positions in the vertical direction, and the outer diameter of the cover ring 9 is larger than the diameter of the gear 6.

[0046] In the initial state, the lower half of the wedge block 10 is in contact with the surface of the linkage disk 11, and the elastic strip 12 is located between the two wedge blocks 10. In the initial state, the elastic strip 12 is in a stretched state.

[0047] The surface of the slide bar 8 is coated with a magnetic attraction layer, and the inner wall of the channel matched with the slide bar 8 provided on the inner wall of the isolation cover 2 is arranged with a magnetic layer which attracts the magnetic attraction layer.

[0048] Different from the first embodiment, this embodiment is an improvement on the phenomenon that the isolation cover 2 can only be applied to specimen tubes 1 of one size. Since the specimen tubes 1 have different thicknesses, this embodiment is adopted to expand the application range of the isolation cover 2. In this embodiment, the number of gears 6 is an even number, and in this embodiment, the lowest cross bar 7 near one end of the rotating plug 3 extends out of the isolation cover 2 and is fixedly connected to the rotating plug 3. At the same time, there is a gap between the abutment block 5 and the inner wall of the isolation cover 2 in the initial state.

[0049] Specifically, when it is necessary to adapt to a thinner specimen tube 1, the slide bar 8 can be squeezed downward to drive the wedge block 10 to move downward, thereby squeezing the linkage disk 11, forcing the linkage disk 11 to move in the direction close to the inner center position of the isolation cover 2, thereby driving the cross bar 7 and the abutment block 5 to move in the same direction. In addition, due to the presence of the cover ring 9, multiple gears 6 in the vertical direction can achieve synchronous lateral movement when meshing (because the cover ring 9 is arranged on both side surfaces of the gear 6 and there is an overlapping portion with the meshing gear 6, so when the top gear 6 moves laterally, the lower gear 6 and the cross bar 7 fixedly sleeved with the gear 6 will move synchronously), thereby achieving the abutment diameter of the abutment block 5 on the same vertical axis to adapt to the isolation protection of specimen tubes 1 with smaller diameters (such as Fig.12 as shown).

[0050] Similarly, in order to adapt to the isolation and protection of specimen tubes 1 with larger diameters, the slide bar 8 can be pulled upward, and the squeezing and pushing effect of the wedge block 10 on the linkage disk 11 is weakened. Under the resetting effect of the elastic strip 12, the uppermost cross bar 7 moves away from the center of the isolation cover 2, thereby allowing the abutment block 5 to approach the inner wall of the isolation cover 2 to adapt to the isolation and protection treatment of specimen tubes 1 with larger diameters.

[0051] In summary, the laboratory sampling device includes a specimen tube 1 and an isolation cover 2. The isolation cover 2 is provided with abutment blocks 5 and a cross bar 7. The abutment blocks 5 form a fish-scale layout, which can effectively prevent the isolation cover 2 from being pulled off the surface of the specimen tube 1. The abutment blocks 5 can also be switched to an upward fish-scale arrangement by releasing the limit plug 31 and cooperating with the reset shaft, so that the originally downward fish-scale-arranged abutment blocks 5 can be switched to an upward fish-scale-arrangement, so that it is easy and labor-saving to pull the isolation cover 2 upward away from the surface of the specimen tube 1, reducing the contamination of blood samples caused by violent disassembly. The storage cost can also be reduced by the reusable isolation cover 2. The isolation protection operation of specimen tubes 1 of different thicknesses can be adapted through the cooperation of the slide bar 8, the cover ring 9, the wedge block 10 and the elastic strip 12.

[0052] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
