Description

Technical Field

[0001] The present application belongs to the technical field of medical tools, and specifically relates to a device for quantitatively taking cervical exfoliated cell preservation fluid. Background Art

[0002] Cervical exfoliated cell preservation fluid refers to a liquid used to preserve cervical exfoliated cells, protect cell integrity and fixation, and can prevent cell shrinkage, dissolution and swelling; and the preservation fluid has strong mucus processing ability and blood cell disintegration ability, which can extend the cell preservation time, making the preserved cells suitable for making cell wax blocks, HPV virus testing, etc. In the prior art, the preservation fluid is usually stored in a bottle, and when it is needed, it is poured into the cavity where the sampling swab is stored, so that the preservation fluid and the cervical exfoliated cells on the swab are fully in contact, so that the cells are separated from the swab and effectively preserved in the preservation fluid.

[0003] The existing method of taking out the preservation solution mainly relies on manual operation, but this leads to many unavoidable operation accidents; for example, when pouring out the preservation solution, the preservation solution spills onto the skin surface of the operator, causing chemical accidents such as skin poisoning. In order to solve this problem, the prior art proposes a solution to avoid the above-mentioned accidents by connecting the preservation solution bottle and the cavity.

[0004] The inventors found that when docking the preservation solution bottle and the cavity, it is difficult for the operator to control the amount of preservation solution poured into the cavity, which can easily cause excessive or insufficient pouring of preservation solution, thereby causing a technical defect of poor preservation of cervical exfoliated cells.

DETAILED DESCRIPTION

[0038] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0039] Please also read Figures 1 to 8 The quantitative taking device for cervical exfoliated cell preservation solution provided by the present application is now described. The quantitative taking device for cervical exfoliated cell preservation solution provided by the present application comprises a box body 1, a cover body 2 and a plurality of sealing components 3.

[0040] The box body 1 is used to be placed on a horizontal plane, and its upper end surface is provided with a liquid storage tank 11 and a storage tank 12 arranged in parallel along the horizontal direction; in the present embodiment, for the convenience of description, the arrangement direction of the liquid storage tank 11 and the storage tank 12 is defined as the left-right direction, and the liquid storage tank 11 is located on the right side of the storage tank 12; and, the inner wall of the liquid storage tank 11 also has a plurality of through holes 13 arranged in parallel along the up-down direction, and each through hole 13 is connected to the storage tank 12.

[0041] It should be noted that, in order to reduce the length of the through hole 13 as much as possible, the through hole 13 used in this embodiment is parallel to the left-right direction in the circumferential direction, and the through hole 13 passes through from the right side of the storage tank 12 to the left side of the liquid storage tank 11.

[0042] The cover body 2 is used to be detachably connected to the upper end of the box body 1 so as to be suitable for closing the liquid storage tank 11 and the material storage tank 12 at the same time; when it is necessary to add the preservation liquid to the liquid storage tank 11, or when it is necessary to take a sampling swab into the material storage tank 12, the cover body 2 can also be partially opened to open the liquid storage tank 11 or the material storage tank 12 separately.

[0043] A plurality of sealing components 3 are arranged on the box body 1 at intervals along the up-down direction, and correspond one-to-one to a plurality of through holes 13 ; in actual use, each sealing component 3 is used to block the corresponding through hole 13 to limit the liquid from passing through the through hole 13 .

[0044] In the embodiment of the present application, the cell preservation fluid can be stored through the fluid storage tank 11, and the sampling swab can be stored through the storage tank 12; on this basis, multiple through holes 13 are blocked at the same time by multiple sealing components 3, so that the spaces where the preservation fluid and the sampling swab are located can be set independently of each other.

[0045] When the preservation liquid needs to be input into the storage tank 12, one of the sealing components 3 can be opened to allow part of the preservation liquid on the upper side of the through hole 13 corresponding to the sealing component 3 to enter the storage tank 12, thereby realizing the liquid amount control of the part of the preservation liquid input into the storage tank 12.

[0046] Compared with the prior art, the quantitative taking device for cervical exfoliated cell preservation solution provided in this embodiment can limit the usage amount of preservation solution to ensure the preservation effect of cervical exfoliated cells.

[0047] It should be noted that, in actual preparation, the cross-sectional area of ​​the liquid storage tank 11 can be made much smaller than the cross-sectional area of ​​the material storage tank 12; by adopting the above technical solution, after the preservation liquid in the liquid storage tank 11 enters the material storage tank 12 through one of the through holes 13 in the open state, the preservation liquid in the material storage tank 12 will not be higher than any through hole 13, thereby avoiding the reflux phenomenon of the preservation liquid passing through the through hole 13 again and entering the liquid storage tank 11.

[0048] In some embodiments, Figure 4 , Figure 7 and Figure 8 As shown, the closing assembly 3 includes a sliding rod 31 and an insert block 32 .

[0049] The sliding rod 31 is disposed in the liquid storage tank 11 , and is slidably connected to the box body 1 along the left-right direction, and an elastic reset member 4 is provided between the sliding rod 31 and the box body 1 .

[0050] The insert block 32 is fixedly connected to the left end of the sliding rod 31 and is suitable for being inserted into the through hole 13 to close the through hole 13 .

[0051] By adopting the above technical solution, when the insert block 32 moves to the left to be inserted into the through hole 13, the through hole 13 is closed and the elastic reset member 4 is in a normal state without elastic deformation; correspondingly, when the insert block 32 moves to the right to be out of the through hole 13, the elastic reset member 4 undergoes elastic deformation.

[0052] In some embodiments, Figure 4 , Figure 7 and Figure 8As shown, the right end of the sliding rod 31 penetrates through the box body 1 and extends out, and the right end of the sliding rod 31 has a control plate 311 extending outward along its radial direction.

[0053] In this embodiment, the elastic return member 4 is a spring which is sleeved on the protruding portion of the sliding rod 31 and whose two ends are respectively connected to the outer wall of the box body 1 and the control board 311 .

[0054] By adopting the above technical solution, when the plug block 32 is inserted into the through hole 13, the spring is in a normal state; when the plug block 32 moves to the right to be separated from the through hole 13, the elastic reset member 4 is in an elastically stretched state. On this basis, the sliding rod 31 can limit the buckling of the spring to improve its stability during use.

[0055] In some embodiments, Figure 4 , Figure 7 and Figure 8 As shown, the through hole 13 is in the shape of a long strip extending in the front-to-back direction; and the insert block 32 is adapted to the shape of the through hole 13 , and the left end surface of the insert block 32 has two cushion blocks 321 arranged in parallel.

[0056] Since the sliding rod 31 adopts a round rod structure, when the insert block 32 moves to the right to disengage from the through hole 13, the sliding rod 31 is suitable for rotating relative to the box body 1 about its own central axis, so that the pad 321 abuts against the inner wall of the left side of the liquid storage tank 11, and the two pads 321 are respectively located on the upper and lower sides of the through hole 13, thereby exposing the space between the through hole 13 and the left end face of the insert block 32, thereby ensuring that the cell preservation fluid can quickly pass through the through hole 13.

[0057] In some embodiments, Figure 4 , Figure 7 and Figure 8 As shown, the right end of the insert block 32 has a blocking piece 322 extending outward.

[0058] By adopting the above technical solution, when the insert block 32 is inserted into the through hole 13, the blocking plate 322 abuts against the inner wall of the left side of the liquid storage tank 11 to limit the sliding rod 31 from moving leftward, thereby preventing the elastic return member 4 from elastically contracting and the sliding rod 31 from vibrating toward the left.

[0059] In some embodiments, Figures 1 to 5 As shown, the cover body 2 includes a first cover plate 21 and a second cover plate 22 .

[0060] The first cover plate 21 is suitable for covering the upper side of the box body 1 , and has a first elastic block 211 on the lower side thereof that is suitable for being embedded in the storage slot 12 .

[0061] The second cover plate 22 is hinged to the first cover plate 21 along the front-to-back direction, and has a second elastic block 221 on its lower side suitable for being embedded in the liquid storage tank 11 .

[0062] In actual use, the liquid storage tank 11 or the storage tank 12 can be opened or closed separately by swinging the second cover plate 22 relative to the first cover plate 21, or swinging the first cover plate 21 relative to the second cover plate 22.

[0063] In some embodiments, Figures 4 to 6 As shown, the lower end of the first elastic block 211 has a first snap ring 212, and the inner wall of the storage tank 12 has a first annular groove 121 suitable for the first snap ring 212 to be embedded; the lower end of the second elastic block 221 has a second snap ring 222, and the inner wall of the liquid storage tank 11 has a second annular groove 111 suitable for the second snap ring 222 to be embedded.

[0064] By adopting the above technical solution, through the clamping relationship between the first clamping ring 212 and the first annular groove 121, and the clamping relationship between the second clamping ring 222 and the second annular groove 111, the embedding strength between the first elastic block 211 and the storage groove 12, and the second elastic block 221 and the liquid storage groove 11 can be strengthened, thereby avoiding losses caused by opening the first cover plate 21 or the second cover plate 22.

[0065] In some embodiments, Figure 5 As shown, the outer peripheral walls of the first cover plate 21 and the second cover plate 22 are provided with a plurality of anti-slip strips 5 arranged at intervals along the thickness direction thereof; when it is necessary to open the first cover plate 21 or the second cover plate 22 separately, the hand can be buckled on the anti-slip strip 5 and force can be applied to increase the friction between the hand and the anti-slip strip 5, thereby ensuring that the first cover plate 21 or the second cover plate 22 can be opened stably.

[0066] In some embodiments, Figure 4 As shown, the cross section of the storage groove 12 is circular, and the bottom of the groove is a concave spherical structure.

[0067] When the sampling swab is placed into the storage groove 12, the end of the sampling swab can fall on the bottom of the spherical structure; by adopting the above technical solution, after the preservation liquid enters the storage groove 12, it can gather at the bottom of the spherical structure to ensure that the end of the sampling swab can evenly contact the preservation liquid, thereby improving the preservation effect of cervical exfoliated cells.

[0068] In some embodiments, Figure 1 and Figure 2 As shown, both sides of the box body 1 in the front-to-back direction are fixedly connected with anti-skid pads 6; when the operator holds the box body 1, he can buckle his fingers on the anti-skid pads 6 to increase the friction between the hand and the box body 1, thereby avoiding the accidental situation that the box body 1 falls off the hand.

[0069] The above content is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
