Description

Technical Field

[0001] This invention relates to the field of medical measurement equipment technology, and in particular to a reading device for accurately measuring the volume of a specific tissue using the water displacement method. Background Technology

[0002] Currently, organ volume is typically measured using the length-width-height multiplication method or the displacement method, both domestically and internationally. However, due to the highly irregular three-dimensional shape of organs or human error in reading, these measurement methods are unscientific and inaccurate.

[0003] Patent CN211740320U discloses a liver tissue volume measuring device, including a base and an operating box. A roller frame is fixedly connected to the bottom of the base, and rollers are rotatably connected to the bottom of the roller frame. A support frame and a battery are fixedly welded to the top of the base, with the battery located inside the support frame. The operating box is located on the top of the support frame, with a glass door on one side and a handle on the surface of the glass door. An indicator light and a control button are located on one side of the operating box, with the control button located below the indicator light. A drainage interface is fixedly connected to the bottom inner side of the operating box, and a connecting pipe is fixedly connected to the bottom of the drainage interface. One end of the connecting pipe is fixedly connected to a wastewater storage tank. The operating box contains a water storage tank and a water injection tank. This application measures and judges the volume of liver tissue by means of drainage, saving operation time and improving work efficiency for medical research.

[0004] However, the measuring device has a complex structure and the liquid changing operation is cumbersome during batch testing. In the existing technology, there is also a method to measure tissue volume by overflow, but after overflow, the water level needs to be read manually, which has the problem of reading error and the tissue being measured will be squeezed during the measurement process, resulting in great damage to the tissue and organs. Therefore, we propose a reading device for accurately measuring the volume of a specific tissue by the drainage method. Summary of the Invention

[0005] To address the problems mentioned in the background section, the present invention provides a reading device for accurately measuring the volume of a specific tissue using a drainage method.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

The upper part of the recovery chamber is sealed to the lower part of the placement platform base plate, and the upper opening of the recovery chamber covers all the drain ports, so as to completely receive the liquid flowing down from the drain ports. The recovery chambers are connected to each other through a collection pipe.

[0012] Preferably, the box compartment is provided with meandering guide rails arranged according to the layout of each placement platform. The guide rails are arranged parallel to each other on both sides of the longitudinally and transversely arranged placement platforms and meander and turn to form a guide path that curves and covers all placement platforms. The guide rails have insert rails that extend to the outside from the top and bottom.

[0013] Preferably, the bottom plate of the main cylinder houses a traveling support, which includes a main frame rod, a traveling ball, and a limiting head. The bottom of the main cylinder has a housing cavity that allows the entire traveling support to be placed inside. The side wall of the housing cavity has a vertically extending limiting groove, and the outer peripheral wall of the limiting head installed on the top of the main frame rod has a limiting slider that slides into the limiting groove.

[0014] Preferably, a horizontal fan compartment is provided on the bottom side wall of the storage cavity.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1

[0030] Reference Figure 1-6 A reading device for accurately measuring the volume of a specific tissue using the drainage method includes a placement box 1, a quantitative cap bottle 2, and an automatic measuring device 3. The placement box 1 has multiple placement platforms 12 arranged longitudinally and laterally in the box compartment 11. The quantitative cap bottle 2 can be installed upside down on the upper part of the placement platform 12 to form a quantitative measuring chamber for measuring tissue volume. The automatic measuring device 3 injects an isotonic measuring solution into the quantitative measuring chamber to measure the volume of the tissue placed in the quantitative measuring chamber.

[0031] The placement platform 12 is protruding on the bottom surface of the box 11. The two ends of the quantitative cap bottle 2 have a mating interface 201 and a sealing port 202, respectively. The inner side of the sealing port 202 has a thread that fits perfectly with the outer circumference of the placement platform 12. After placing the tissue sample cloth to be tested one by one on each placement platform 12, the user rotates and screws the quantitative cap bottle 2 to the placement platform 12 to seal it, thus fixing the quantitative cap bottle 2 in the placement box 1.

[0032] The lower part of the box compartment 11 has a substrate compartment 13. Several mating components 4 corresponding to the placement stage 12 are installed in the substrate compartment 13. The mating components 4 include a central control 41, a vertical moving column 42, a connecting frame 43 and a sealing plug 44 that are electrically connected to the outside. The central control 41 is fixedly installed at the center of the axis of the placement stage 12. The vertical moving column 42 is installed at the lower end of the central control 41 and extends from the bottom plate of the box compartment 11 to the substrate compartment 13. The central control 41 can drive the vertical moving column 42 and the connecting frame 43 installed on the periphery of the vertical moving column 42 to move vertically.

[0033] The placement platform 12 has at least one through-flow outlet 101. The bottom plate of the compartment 11 has a drain outlet 102 corresponding to each outlet 101. The cross-section of the drain outlet 102 is larger than that of the outlet 101, and the cross-section of the drain outlet 102 covers the entire outlet 101. The sealing plug 44 is installed on the top of the connecting frame 43 and can pass through the drain outlet 102 and be inserted into the outlet 101. When the sealing plug 44 is inserted into the outlet 101, it can interact with the outlet 101. The edges are tightly pressed together to block the outlet 101, thereby preventing the liquid in the quantitative measurement chamber from flowing down. The central control unit 41 drives the vertical moving column 42 to move down, causing the sealing plug 44 installed on the upper end of the connecting frame 43 to move down into the drain port 102. When the sealing plug 44 is completely inserted into the drain port 102 and detached from the outlet 101, the outlet 101 will no longer be blocked by the sealing plug 44, and the liquid in the quantitative measurement chamber will flow down and be discharged through the outlet 101 and the drain port 102.

[0034] The substrate chamber 13 is also provided with a plurality of recovery chambers 14 corresponding to the mating components 4. The upper part of the recovery chamber 14 is sealed to the lower part of the base plate of the placement platform 12. The upper opening of the recovery chamber 14 covers all the drain ports 102, thereby completely receiving the liquid flowing down from the drain ports 102. The recovery chambers 14 are connected to each other through a collection pipe 15. The liquid collected in each recovery chamber 14 will be led out to the outside of the substrate chamber 13 for collection and processing through the collection pipe 15.

[0035] A vertical rod 16 is installed on the upper surface of the placement platform 12. The vertical rod 16 is hollow inside and has a float 17. The bottom end of the vertical rod 16 has a connection between the internal space of the vertical rod 16 and the internal space of the quantitative measurement chamber. After liquid is injected into the quantitative measurement chamber, some of it will flow into the vertical rod 16, causing the float 17 to float up. When the quantitative measurement chamber is full, the float 17 floats to the top of the vertical rod 16 and stops floating. The opening of the vertical rod 16 to the outside does not allow the float 17 to move out, so that the float 17 is always kept inside the vertical rod 16.

[0036] The central control unit 41 is equipped with a ranging head 45 at its top. The ranging head 45 extends out of the bottom surface of the box 11 and is located at the bottom of the vertical rod 16. It monitors the distance between itself and the float 17 in real time. After the ranging head 45 detects that the float 17 is rising away, the central control unit 41 will enter a ready state. After the float 17 is held at a position away from the ranging head 45 for a predetermined time, the central control unit 41 will drive the vertical column 42 to move down and release the liquid in the quantitative measurement chamber until the float 17 moves back to its original position with the liquid level.

[0037] Example 2

[0038] Reference Figure 1-6 The difference between this embodiment and Embodiment 1 is that the automatic measuring device 3 includes a main cylinder 31, a control panel 32, an injection head 33, and a liquid supply connector 34. The main cylinder 31 is equipped with a battery, a metering pump, and a control main board. The battery can power the metering pump and the control main board. The user can send commands to the control main board through the control panel 32. The metering pump is connected to the injection head 33 and the liquid supply connector 34 respectively. The externally supplied measuring liquid flows into the main cylinder 31 through the liquid supply connector 34, and then is pumped out by the injection head 33 by the metering pump. The metering pump can accurately obtain the specific volume data of the liquid flowing from the liquid supply connector 34 to the injection head 33.

[0039] The bottom of the injection head 33 is equipped with a liquid level detection head 35 that is electrically connected to the control motherboard. After the injection head 33 is connected to the interface 201, the bottom of the liquid level detection head 35 is exactly at the quantitative liquid level surface of the quantitative cap bottle 2.

[0040] When performing tissue volume determination, the user first inputs the quantitative volume of the quantitative cap bottle 2 into the control main board through the control panel 32. Then, the automatic measuring device 3 continuously injects the measuring liquid into the quantitative measuring chamber. When the liquid level in the quantitative measuring chamber reaches the quantitative level, it will be detected by the liquid level probe 35. The detection signal is transmitted to the control main board, causing the metering pump to immediately stop injecting the measuring liquid into the quantitative measuring chamber. At this time, the difference between the actual volume of measuring liquid injected into the quantitative measuring chamber by the quantitative cap bottle 2 and the actual volume of measuring liquid measured by the quantitative volume metering pump is the actual volume of the tissue to be tested in the quantitative measuring chamber.

[0041] Preferably, the control motherboard may also be equipped with a Bluetooth or wireless module, so as to transmit the measured data to an external receiving device in a timely and accurate manner for storage and analysis.

[0042] Example 3

[0043] Reference Figure 1-6 The difference between this embodiment and embodiment 2 is that the box 11 is provided with a meandering guide rail 18 arranged according to the arrangement of each placement platform 12, and the base plate of the main unit cylinder 31 is provided with a traveling bracket 36. The user can place the main unit cylinder 31 with the traveling bracket 36 on the guide rail 18, and the automatic measuring device 3 can align with the quantitative cap bottle 2 on each placement platform 12 and measure the volume of the tissue to be tested inside according to the guidance of the guide rail 18.

[0044] The traveling support 36 includes a main frame rod 361, a traveling ball 362, and a limiting head 363. The limiting head 363 and the traveling ball 362 are respectively installed at the upper and lower ends of the main frame rod 361. The bottom of the main cylinder 31 is provided with a receiving cavity 301, which allows the entire traveling support 36 to be placed inside. The side wall of the receiving cavity 301 has a vertically extending limiting groove 302. The outer peripheral wall of the limiting head 363 has a limiting slider 364 that slides into the limiting groove 302. The bottom of the limiting groove 302 does not extend to the bottom of the receiving cavity 301, so that the main frame rod 361 with the limiting head 363 installed cannot move downward out of the receiving cavity 301. The limiting slider 364, which is engaged in the limiting groove 302, can also keep the main frame rod 361 in a fixed rotational position.

[0045] A horizontal fan compartment 303 is provided on the bottom side wall of the storage cavity 301. A portion of the horizontal fan compartment 303 covers the cross-sectional plane of the storage cavity 301 and is connected to it. A locking strip 37 is installed inside the horizontal fan compartment 303. One end of the locking strip 37 is installed inside the horizontal fan compartment 303, and the locking strip 37 can rotate axially within the horizontal fan compartment 303 with this end as its rotation center. During the rotation of the locking strip 37, the other end of the locking strip 37 can move into the storage cavity 301. A locking groove 304 is provided at the upper end of the main frame rod 361. When the limiting head 363 moves into the storage cavity 301... At the bottom, the locking slot 304 corresponds exactly to the vertical position of the horizontal fan compartment 303. When the main frame rod 361 moves within the storage cavity 301, the locking strip 37 moves into the horizontal fan compartment 303 to avoid the movement path of the main frame rod 361. When the main frame rod 361 extends out of the storage cavity 301 and the locking slot 304 corresponds to the horizontal fan compartment 303, the locking strip 37 can rotate and move into the locking slot 304. The thickness of the locking strip 37 is consistent with the height of the locking slot 304 so that the vertical position of the main frame rod 361 can be locked after the locking strip 37 moves into the locking slot 304.

[0046] The rotating axis of the locking strip 37 extends downward beyond the bottom of the main cylinder 31 and connects with the enclosing rotating plate 38. The upper surface of the enclosing rotating plate 38 is in close contact with the bottom surface of the main cylinder 31, and the enclosing rotating plate 38 has a blocking part that can completely cover the bottom outlet of the storage cavity 301. The blocking part is located away from the end of the rotating shaft connected to the locking strip 37. The relative positions of the blocking part of the enclosing rotating plate 38 and the locking strip 37 are such that when the locking strip 37 is in the locking slot 304, the blocking part of the enclosing rotating plate 38 is in a position that avoids the bottom outlet of the storage cavity 301, and when the blocking part of the enclosing rotating plate 38 moves to a position that covers the bottom outlet of the storage cavity 301, the locking strip 37 is in a position that moves out of the locking slot 304.

[0047] It is worth mentioning that the locking strip 37 and the closing rotating plate 38 can also deflect synchronously, so that while the locking strip 37 is in the position of being removed from the locking slot 304, the closing rotating plate 38 has not yet moved to the position of obscuring the bottom outlet of the storage cavity 301. When the locking strip 37 and the closing rotating plate 38 deflect to this position, the main frame rod 361 can move freely in the storage cavity 301 without being affected by the locking strip 37 and the closing rotating plate 38. After the main frame rod 361 is fully retracted into the storage cavity 301, the user can move the closing rotating plate 38 through the opening. Rotate to the position that covers the bottom outlet of the storage cavity 301 to store the main frame rod 361 in the storage cavity 301. After the main frame rod 361 is fully extended from the storage cavity 301, the user can adjust the closing rotating plate 38 to rotate the locking strip 37 to the position that moves into the locking slot 304 to lock the vertical position of the main frame rod 361. It can be understood that the friction between the closing rotating plate 38 and the bottom surface of the main cylinder 31 can make the locking strip 37 and the closing rotating plate 38 rotate to the designated position and remain in that position until the position is changed due to the user's force.

[0048] The ball ball 362 is installed in the ball chamber 305 at the lower end of the main frame 361. The diameter of the channel leading from the ball chamber 305 to the outside of the main frame 361 is smaller than the diameter of the ball ball 362, so that the lower end of the ball ball 362 can protrude from the bottom of the ball chamber 305 but will not fall out of the ball chamber 305 completely. There is a gap between the upper part of the ball ball 362 and the top of the ball chamber 305. A drive shaft 365 is provided in this gap. The drive shaft 365 is driven by a motor installed at the bottom of the main frame 361 to rotate axially, thereby driving the ball ball 362, which is in close contact with it, to roll and rotate in the ball chamber 305 by means of friction.

[0049] The guide rail 18 is arranged parallel to both sides of the longitudinally and transversely arranged placement platform 12 and meanders to form a curved guide path covering all placement platforms 12. The guide rail 18 has an insert rail 103 that extends vertically to the outside. The insert rail 103 allows the main frame rod 361 to be inserted into it. In this way, the driven rolling ball 362 will contact the bottom surface of the insert rail 103, causing the entire automatic measuring device 3 to move along the guide path formed by the guide rail 18.

[0050] The lower end of the main frame rod 361 is provided with a limiting ring 366 on the outer peripheral wall of the portion into which the insertion rail 103 can be inserted. The side wall of the insertion rail 103 has a limiting rail 104 that allows the limiting ring 366 to be inserted. The diameter of the limiting ring 366 is larger than that of the main frame rod 361. The starting and ending ends of the guide rail 18 have insertion channels that allow the limiting ring 366 to move down and be inserted into the insertion rail 103. After the limiting ring 366 is inserted into the insertion rail 103, it can move into the limiting rail 104. After the limiting ring 366 moves into the limiting rail 104, its upper and lower surfaces are in close contact with the upper and lower surfaces of the limiting rail 104, so that the main frame rod 361 will not tip over after being vertically inserted into the insertion rail 103.

[0051] The insertion rail 103 has a recess 105 at a position corresponding to each placement platform 12. When the main frame rod 361 is fully extended from the receiving cavity 301 and inserted into the insertion rail 103, the injection head 33 is above the interface 201. As the automatic measuring device 3 moves along the guide rail 18, the injection head 33 will move directly above each interface 201. At this time, the ball ball 362 will fall into the recess 105, preventing the automatic measuring device 3 from continuing to move. After the ball ball 362 falls into the recess 105, the injection head 33 is precisely inserted into the interface 201, allowing the measuring liquid to be injected into the quantitative measuring cavity. It is worth mentioning that the limiting rail 104 also has a recessed part at a position corresponding to the recess 105, so that the limiting ring 366 can move down synchronously with the main frame rod 361 and keep the main frame rod 361 upright.

[0052] The bottom of the recessed pit 105 is provided with an upper lifting block 19. The upper lifting block 19 is driven by a hydraulic device (not shown in the figure) installed at the bottom to move vertically, thereby lifting the lower end of the main frame rod 361 that is sunken in the recessed pit 105 and continuing to move. Under normal circumstances, the upper lifting block 19 is held at the bottom of the recessed pit 105 by the hydraulic device, and the hydraulic device is electrically connected to the central control unit 41. Only when the central control unit 41 controls the vertical moving column 42 to move down to discharge materials will it control the hydraulic device to lift the upper lifting block 19.
