Description

Technical Field

[0001] The invention relates to the technical field of specimen storage, in particular to a pathological specimen fixative liquid adding table. Background Art

[0002] After pathological specimens are obtained during surgery or biopsy, they should be placed in an appropriate amount of fixative immediately or as quickly as possible to ensure that the specimens are well fixed. Commonly used fixatives include 10% neutral formaldehyde buffer, Bouin solution, Zenker solution, etc. These fixatives can effectively fix tissues and cells and maintain their original morphology and composition.

[0003] The fixation of pathological specimens requires the addition of an appropriate amount of fixative. However, the current method of adding fixative to pathological specimens generally adopts manual addition, which makes it difficult to control the amount of fixative added. It is easy for the volume of added fixative to be insufficient, and the fixation of pathological specimens cannot be achieved. It needs to be added repeatedly little by little, which is troublesome to operate. In addition, manual addition of fixative is also prone to excessive addition, causing the fixative to overflow from the pathological specimen storage box.

[0004] In addition, when adding liquid manually, the speed of adding the fixative cannot be controlled. If the adding speed is too fast, the fixative and the fixative in the pathology specimen storage box will collide, causing splashing when the fixative is added. Since the fixative is mostly a chemical reagent with certain corrosiveness and toxicity, the splashed fixative will not only contaminate the table, but also cause harm to the staff. In order to solve this problem, we proposed a pathology specimen fixative adding table. Summary of the invention

[0005] In view of the above or existing problems in the prior art that the amount of fixative added cannot be controlled when adding the fixative to the pathological specimens, and that the fixative splashes during addition may contaminate the desktop and injure the staff, the present invention is proposed.

[0006] Therefore, the object of the present invention is to provide a pathological specimen fixative liquid adding station.

[0009] As a preferred solution of the pathological specimen fixative liquid adding station of the present invention, the lifting assembly includes a connecting ring tube rotatably installed on the liquid outlet pipe, and a driving ring is provided on the inner wall of the connecting ring tube, and a push rod is provided at the bottom end of the sealing plug, and the push rod and the top end of the driving ring are in conflict.

[0010] As a preferred solution of the pathological specimen fixative liquid adding station of the present invention, wherein: a sealing plane and a lifting plane are arranged on the driving ring, and a driving inclined plane is arranged between the sealing plane and the lifting plane.

[0011] As a preferred solution of the pathological specimen fixative liquid adding station of the present invention, a first stopper is provided at one end of the lifting plane away from the driving inclined plane, and a second stopper is provided at one end of the sealing plane away from the driving inclined plane.

[0012] As a preferred solution of the pathological specimen fixative liquid adding station of the present invention, wherein: a rectangular hole is opened on the disc, and a rectangular column is movably installed in the rectangular hole, and the bottom end of the rectangular column is fixedly connected to the top end of the sealing plug.

[0013] As a preferred solution of the pathological specimen fixative liquid adding station of the present invention, wherein: a ball groove is formed at one end of the push rod away from the sealing plug, and a ball is arranged inside the ball groove.

[0014] As a preferred solution of the pathological specimen fixative liquid adding station of the present invention, wherein: the limiting rods are provided in two groups, and the two groups of limiting rods are staggeredly arranged at the top end of the floating plate along the length direction thereof.

[0015] As a preferred solution of the pathological specimen fixative liquid adding table of the present invention, wherein: a driving rod is arranged on the circumferential side wall of the connecting ring tube, and the driving rod is cylindrical, a quadrant point on the retaining ring is located on one side of the vertical plane of the axis of the driving rod, and the retaining ring pushes the driving rod to rotate along the arc surface of the driving rod, so that the push rod is separated from the lifting plane.

A controller electrically connected to the electric lifting column is arranged on one side of the liquid storage tank.

[0017] The beneficial effects of the pathological specimen fixative liquid adding station of the present invention are:

[0018] 1.

[0019] 2. The present invention combines a sealing component, a lifting component and a liquid level control mechanism, so that when the liquid storage tank adds fixative to the pathological specimen storage box, as the liquid level of the fixative in the pathological specimen storage box increases, the floating plate is driven to move up, thereby driving the limit rod to move up. When the liquid level reaches a suitable position, the retaining ring on the limit rod and the cylindrical driving rod on the lifting component are squeezed and driven to rotate the driving ring, thereby unlocking the lifting of the sealing component, so that the sealing plug seals the liquid outlet pipe under the action of the squeezing spring, thereby stopping the addition of liquid to the pathological specimen storage box.

DETAILED DESCRIPTION

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1, reference Figures 1 to 6, which is the first embodiment of the present invention, and provides a pathological specimen fixative liquid adding table, which solves the problem that the fixative will splash onto the table and the staff when adding, causing table pollution and staff injury. It includes a table mechanism 1, which includes a base 101, and also includes an electric lifting column 102 and a limit support column 103 arranged on the base 101, as well as a splash plate 104 arranged on the limit support column 103 and a support plate 105 arranged on the top of the electric lifting column 102. The four corners at the bottom of the base 101 are all provided with The electric lifting column 102 is fixedly installed at the center of the base 101, and four limit support columns 103 are arranged, which are respectively fixedly installed at the four corners of the top of the base 101. The center position of the support plate 105 is fixedly connected to the top of the electric lifting column 102, and movable holes are opened at the four corners of the support plate 105. The movable holes and the limit support columns 103 are slidably matched, so that the support plate 105 can move up and down stably under the push of the electric lifting column 102, and the splash plate 104 is fixedly installed on the top of the limit support column 103.

[0032] The liquid storage mechanism 2 includes a liquid storage tank 201 arranged at the top of the splash plate 104, and a liquid outlet pipe 202 is arranged at the bottom of the liquid storage tank 201, a sealing component 3 is arranged at the connection between the liquid storage tank 201 and the liquid outlet pipe 202, and a lifting component 4 is rotatably installed at the bottom of the liquid outlet pipe 202, and a liquid adding pipe 5 is arranged at the bottom of the lifting component 4, a cover plate 203 is rotatably installed at the top of the liquid storage tank 201, and brackets 204 are arranged at the four corners of the bottom of the liquid storage tank 201. By rotating and opening the cover plate 203, a fixing liquid can be added to the liquid storage tank 201. It should be noted that in order to avoid To prevent excessive sputtering of the fixing liquid, the liquid level should not be too high when adding. The bottom end of the bracket 204 is welded to the four corners of the top of the splash plate 104 to support the liquid storage tank 201. The liquid outlet pipe 202 is welded to the center position of the bottom end of the liquid storage tank 201. The sealing component 3 and the pipe mouth of the liquid outlet pipe 202 correspond to each other, and a sealing bearing is embedded in the bottom end of the liquid outlet pipe 202. The top end of the lifting component 4 and the sealing bearing at the bottom end of the liquid outlet pipe 202 are fixedly connected. The top end of the liquid adding pipe 5 is also embedded with a sealing bearing. The bottom end of the lifting component 4 and the sealing bearing at the top end of the liquid adding pipe 5 are fixedly connected.

[0033] Specifically, when adding fixative to the pathological specimen storage box, the pathological specimen storage box is first placed on the top of the support plate 105, and then the support plate 105 is pushed upward by the electric lifting column 102, so that the pathological specimen storage box is in contact with the bottom end of the zero-stick splash plate 104, so that the pathological specimen storage box is in a sealed state, and the lifting component 4 is driven by rotating and contacting with the sealing component 3, so that the sealing component 3 is opened, so that the fixative in the liquid storage box 201 flows through the outflow pipe 202, the lifting component 4 and the liquid adding pipe 5, wherein the liquid adding pipe 5 passes through the splash plate 104 and extends to the bottom thereof, so that the fixative flowing through the liquid adding pipe 5 flows into the pathological specimen storage box, completing the addition of the fixative.

[0034] The sealing assembly 3 includes a supporting rod 301 arranged in an annular array at the connection point between the liquid storage tank 201 and the liquid outlet pipe 202, and a disc 302 is welded on the top of the supporting rod 301, and an extrusion spring 303 is welded on the bottom of the disc 302, and a sealing plug 304 is fixedly connected to the bottom of the extrusion spring 303. Three supporting rods 301 are arranged in an annular array about one end of the liquid outlet pipe 202, and the diameter of the annular array is larger than the inner diameter of the liquid outlet pipe 202. The disc 302 is welded to the top of the three supporting rods 301 of the annular array, and the diameter of the sealing plug 304 is the same as the diameter of the three supporting rods 301 of the annular array, so that the sealing plug 304 can move up and down between the three supporting rods 301 of the annular array. When the lifting assembly 4 does not resist and lift the sealing assembly 3, the elastic force of the extrusion spring 303 presses the sealing plug 304 against the pipe mouth of the liquid outlet pipe 202, and achieves sealing under the water pressure of the fixed liquid.

[0035] The lifting assembly 4 includes a connecting ring tube 401 rotatably mounted on the liquid outlet pipe 202, and a driving ring 402 is arranged on the inner wall of the connecting ring tube 401, a push rod 403 is arranged at the bottom end of the sealing plug 304, and the push rod 403 and the top of the driving ring 402 are in conflict, and plug-in fixing pipes are arranged at the top and bottom ends of the connecting ring tube 401 for plugging and fixing with the sealing bearing, so that the connecting ring tube 401, the liquid outlet pipe 202 and the liquid adding pipe 5 are connected, and the driving ring 402 is arranged in a semi-circular shape. A sealing plane 404 and a lifting plane 405 are provided on the driving ring 402, and a driving inclined plane 406 is provided between the sealing plane 404 and the lifting plane 405. The lifting plane 405 is higher than the sealing plane 404. When the connecting ring tube 401 rotates, the sealing plane 404, the driving inclined plane 406 and the lifting plane 405 are driven to rotate together, so that the ejector rod 403 will be converted on the sealing plane 404, the driving inclined plane 406 and the lifting plane 405.

[0036] Further, the top rod 403 is as follows Figure 5 As shown, the sealing plug 304 is located at a position off-axis at the bottom end thereof, and its purpose is to adapt to the sealing plane 404 , the driving inclined surface 406 and the lifting plane 405 provided on the driving ring 402 .

[0037] Specifically, when the sealing plug 304 seals and blocks the liquid outlet pipe 202, the bottom end of the push rod 403 is flush with the sealing plane 404 or higher than the sealing plane 404. As the connecting ring tube 401 rotates, the driving inclined surface 406 moves below the push rod 403. The driving inclined surface 406 is used to connect the sealing plane 404 and the lifting plane 405. Therefore, the heights of the two ends of the driving inclined surface 406 are different. Then, when the connecting ring tube 401 rotates, the push rod 403 will be lifted upward through the driving inclined surface 406, thereby gradually lifting the sealing plug 304, so that the fixing liquid in the liquid storage tank 201 flows into the pathological specimen storage box through the connecting ring tube 401, the liquid outlet pipe 202 and the liquid adding tube 5. When the push rod 403 moves to conflict with the lifting plane 405, the sealing plug 304 is in a persistent lifting state, and there is no need to manually support the connecting ring tube 401.

[0038] A rectangular hole 305 is provided on the disc 302, and a rectangular column 306 is movably installed in the rectangular hole 305. The bottom end of the rectangular column 306 is fixedly connected to the top end of the sealing plug 304. The rectangular hole 305 is provided at the center of the disc 302. The sealing plug 304 is limited again by the movably plugged connection between the rectangular column 306 and the rectangular hole 305, so that when the push rod 403 lifts the sealing plug 304, it avoids pushing the sealing plug 304 sideways, so that only one side of the sealing plug 304 is opened, resulting in a small flow rate of the fixed liquid from the liquid storage tank 201 to the liquid outlet pipe 202, thereby affecting the efficiency of adding the fixed liquid.

[0039] Example 2, reference Figures 1 to 6 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a liquid level control mechanism 6 for a pathological specimen fixative liquid adding station, which solves the problem that the amount of fixative added cannot be controlled when adding pathological specimen fixative. It includes a liquid level control mechanism 6, which includes a limiting through hole 106 opened on the splash plate 104, and a limiting rod 601 is slidably installed in the limiting through hole 106, a floating plate 602 is provided at the bottom end of the limiting rod 601, and an avoidance through hole 603 corresponding to the liquid adding tube 5 is provided on the floating plate 602, a retaining ring 604 is provided on the top tube of the limiting rod 601, and two groups of limiting rods 601 are provided, and the two groups of limiting rods 601 are staggered at the top of the floating plate 602 along its length direction.

[0040] In this embodiment, two limiting holes 106 are provided, corresponding to two limiting rods 601 respectively. The two limiting rods 601 are staggered along the length direction of the top of the floating plate 602, so that when the floating plate 602 rises due to the buoyancy of the fixed liquid, the floating plate 602 can rise stably and horizontally. The retaining ring 604 is welded to the top of the limiting rod 601 and is coaxially arranged with the limiting rod 601. The diameter of the retaining ring 604 is larger than the inner diameter of the limiting hole 106. In the initial state, the floating plate 602 falls due to gravity, so that the retaining ring 604 fits the top of the splash plate 104. At this time, the bottom end of the liquid adding tube 5 still passes through the avoidance hole 603 and extends to the floating plate 602, so that the fixed liquid flowing out of the liquid adding tube 5 will not hit the top of the floating plate 602.

[0041] A driving rod 409 is arranged on the circumferential side wall of the connecting ring tube 401, and the driving rod 409 is cylindrical. A quadrant point on the retaining ring 604 is located on one side of the vertical plane of the axis of the driving rod 409. The retaining ring 604 pushes the driving rod 409 to rotate along the arc surface of the driving rod 409, so that the top rod 403 is separated from the lifting plane 405.

[0042] In this embodiment, Figure 6 As shown, the top rod 403 is located at the top plane 405. At this time, a quadrant point on the retaining ring 604 is located on one side of the axis of the driving rod 409, so that as the level of the fixed liquid increases, the buoyancy of the fixed liquid drives the floating plate 602 to move upward, so that the limiting rod 601 moves upward along the limiting through hole 106, and a quadrant point of the retaining ring 604 at the top of the limiting rod 601 contacts the arc surface of the driving rod 409. As the liquid level continues to rise, the floating plate 602 gradually fits the splash plate 104, and the retaining ring 604 uses the arc surface of the driving rod 409 as the driving surface, pushing the driving rod 409 counterclockwise ( Figure 6 The push rod 403 is rotated in the direction of the middle part, so that the push rod 403 moves from the lifting plane 405 to the high inclined plane of the driving inclined plane 406, and at this time, the extrusion spring 303 pushes the sealing plug 304 to move downward, thereby driving the push rod 403 to move downward to squeeze and push the connecting ring tube 401 to rotate, until the push rod 403 moves to the sealing plane 404 area. At this time, the sealing plug 304 does not have the lifting force of the push rod 403, thereby realizing the sealing of the liquid outlet pipe 202 and stopping the further liquid addition, thereby avoiding the occurrence of excessive liquid addition or insufficient liquid addition of the fixing liquid.

[0043] A first stopper 407 is provided at one end of the lifting plane 405 away from the driving inclined plane 406, and a second stopper 408 is provided at one end of the sealing plane 404 away from the driving inclined plane 406. The setting of the first stopper 407 can prevent the connecting ring tube 401 from rotating at an excessively large rotation angle when the connecting ring tube 401 is manually driven to rotate, resulting in a mismatch between the position of the driving rod 409 on the side wall of the connecting ring tube 401 and the position of the retaining ring 604, thereby resulting in the inability to push the driving rod 409 when the retaining ring 604 moves upward, causing the connecting ring tube 401 to rotate.

[0044] A ball groove 307 is provided at one end of the push rod 403 away from the sealing plug 304, and a ball 308 is arranged inside the ball groove 307. The bottom end of the push rod 403 is provided with a rotating ball 308, which makes it easier for the retaining ring 604 to push the driving rod 409 under the action of buoyancy.

[0045] Furthermore, when the connecting ring tube 401 rotates, the extrusion spring 303 pushes the sealing plug 304 downward, so that the push rod 403 always contacts the top of the driving ring 402, and its friction force drives the sealing plug 304 and the push rod 403 to rotate. However, since the bottom end of the push rod 403 is provided with a ball 308, when the connecting ring tube 401 rotates to a certain angle, the push rod 403 enters the lifting plane 405 from the driving inclined surface 406 and fits the first stopper 407. However, due to the change in the position of the push rod 403 at this time, the driving rod 409 on the outer wall of the connecting ring tube 401 cannot correspond to the stopper ring 604. The movable plugging of the rectangular column 306 and the rectangular hole 305 in the present invention avoids the rotation of the push rod 403, so that when the push rod 403 fits the first stopper 407, the driving rod 409 and the stopper ring 604 can be driven accordingly. A controller 7 electrically connected to the electric lifting column 102 is provided on one side of the liquid storage tank 201.

[0046] In this embodiment, two control buttons for lifting and lowering are provided on the controller 7 , and the lifting and lowering of the electric lifting column 102 are controlled by the control buttons.

[0047] The rest of the structure is the same as that of Example 1.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
