Description

Technical Field

[0001] This invention relates to the field of reagent extraction technology, specifically to a high-risk reagent extractor. Background Technology

[0002] High-risk reagents are those with a high degree of danger, mainly used in medical or laboratory work. Improper use can be life-threatening. For example, if a sample cannot be tested immediately after collection, especially a urine sample collected more than 12 hours ago, preservatives such as toluene or formaldehyde are usually added. These are used to prevent decay and to fix the organic components in the urine; toluene also helps to prevent air from entering the liquid. However, these reagents are extremely harmful to the human body, therefore their use is subject to strict requirements.

[0003] Currently, when extracting some high-risk reagents, most of the extraction is done using syringes. The reagents are squeezed out using syringes, but this method cannot quickly seal the mouths of reagent bottles of various sizes during the extraction process. This can lead to the leakage of toxic gases generated during reagent evaporation, which can harm the health of workers. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention proposes a high-risk reagent extractor to solve the technical problem mentioned in the background art, where most existing devices for extracting high-risk reagents only use syringes to extract the reagents, failing to quickly seal the mouths of reagent bottles of various sizes during the extraction process. This leads to the leakage of toxic gases generated during reagent evaporation, causing harm to workers.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-risk reagent extractor, comprising:

[0006] The mounting shell is provided with an outlet pipe and an inlet pipe, and the mounting shell is provided with a liquid extraction mechanism that transports the reagent from the inlet pipe to the outlet pipe.

[0007] An installation pipe is connected to the installation shell, and a conical plug is provided at the bottom of the installation pipe. The water inlet pipe passes through the conical plug and extends outward.

[0008] Two sets of clamping frames are arranged opposite each other on both sides of the conical plug. A control mechanism connected to the two sets of clamping frames is provided on the mounting tube to drive the two sets of clamping frames to open and close.

[0009] A lifting assembly is mounted on the mounting tube and connected to the two sets of clamps to drive the two sets of clamps to rise.

[0010] Furthermore, the liquid extraction mechanism includes:

[0011] A water pump pipe is disposed inside the mounting housing, and a piston that can slide along its axis is disposed inside the water pump pipe;

[0012] A liquid inlet check valve is installed on and connected to the water inlet pipe, and the water inlet pipe is connected to the liquid inlet check valve; and

[0013] A liquid discharge check valve is installed on and connected to the water pumping pipe, and the water outlet pipe is connected to the liquid discharge check valve.

[0014] Furthermore, the control mechanism includes:

[0015] A movable sleeve is fitted onto the mounting tube in a way that allows it to be raised and lowered along its axis;

[0016] The first mounting bracket is slidably mounted on the movable sleeve, and a set of clamping brackets is fixedly mounted on the bottom of the first mounting bracket. The first mounting bracket is provided with a first pressing plate.

[0017] A second mounting bracket is fitted onto the movable sleeve and slidably connected to the first mounting bracket. Another set of clamping brackets is fixedly disposed at the bottom of the second mounting bracket. A second pressing plate is provided on the second mounting bracket.

[0018] The first elastic element is provided in two sets, with one end abutting against the movable sleeve and the other end abutting against the first button and the second button respectively.

[0019] Furthermore, the first mounting bracket and the second mounting bracket are connected by a fixing mechanism, which fixes the relative positions of the first mounting bracket and the second mounting bracket.

[0020] Furthermore, the fixing mechanism includes:

[0021] The ratchet block is mounted on the second mounting bracket in a height-adjustable manner;

[0022] A ratchet rack is mounted on the first mounting bracket, and the ratchet block is engaged on the ratchet rack;

[0023] A button is inserted through the second button plate in a direction perpendicular to the second button plate, with one end extending out of the second button plate;

[0024] A second elastic element is disposed between the button and the movable sleeve; and

[0025] A drive component, disposed on the button and connected to the ratchet block, drives the ratchet block to rise and disengage from the ratchet rack when the button is pressed.

[0026] Furthermore, the driving component includes:

[0027] A movable bracket, mounted on the button, and slidably mounted on the second mounting bracket; a connecting seat, mounted on the ratchet block, having an inclined groove formed thereon; and

[0028] The drive column is mounted on the movable frame and is slidably engaged in the inclined groove.

[0029] Furthermore, the lifting component includes:

[0030] A stop plate is disposed at the end of the mounting tube; and

[0031] The third elastic element is disposed between the second mounting bracket and the stop plate.

[0032] Furthermore, the bottom of the stop plate is circumferentially arranged with multiple sets of buckles, and the conical plug is circumferentially arranged with multiple sets of locking blocks, with the multiple sets of locking blocks respectively locked in the multiple sets of buckles.

[0033] Furthermore, a sealing ring is provided between the stop plate and the conical plug.

[0034] Furthermore, the bottom of the mounting housing is provided with a threaded tube communicating with it, and the mounting tube is screwed onto the threaded tube.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] 1. In use, this extractor can be controlled by a control mechanism to open and close two sets of clamps. After the clamps are opened, the conical plug and water inlet tube are inserted into the bottle mouth of the high-risk reagent to seal the bottle mouth. The control mechanism then controls the two sets of clamps to close, clamping them onto the threads or neck seat of the reagent bottle for installation. Under the action of the lifting component, the two sets of clamps rise, causing the conical plug to exert a downward force to effectively seal the bottle mouth. The high-risk reagent can then be extracted and used through the extraction mechanism. This extractor can quickly seal and fix the bottle mouths of reagent bottles of different sizes, effectively preventing the volatilization of high-risk reagents from causing harm to workers during use.

[0037] 2. During the closing process of the two sets of clamping frames in this extractor, the first and second mounting frames move in opposite directions, causing the ratchet block to slide along the ratchet rack. The ratchet block and ratchet rack work together to create a one-way self-locking mechanism for the first and second mounting frames, effectively preventing them from sliding in opposite directions during use and opening the clamping frames. This effectively secures the bottle openings of high-risk reagent bottles, improving the reliability and safety of the device. When disassembly is required, pressing the button and the first press plate compresses the second elastic frame, causing the movable frame to slide relative to the second mounting frame. This, in turn, moves the drive column. During this movement, the drive column, through its interaction with the inclined groove, causes the ratchet block to rise and disengage from the ratchet rack, releasing the locking of the first and second mounting frames. Pressing the first and second press plates then opens the two sets of clamping frames, allowing for disassembly of the extractor and improving its ease of use. Attached Figure Description

[0052] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0053] Example:

[0054] like Figure 1 , 2 As shown, the present invention provides a high-risk reagent extractor, including a mounting shell 101, an outlet pipe 105 and an inlet pipe 107 disposed on the mounting shell 101, and a liquid extraction mechanism disposed inside the mounting shell 101 for transporting reagents from the inlet pipe 107 to the outlet pipe 105. The liquid extraction mechanism includes a liquid extraction pipe 102 disposed inside the mounting shell 101, a piston 103 disposed inside the liquid extraction pipe 102 that can slide along its axis, and an inlet check valve 106 and an outlet check valve 104 disposed on the liquid extraction pipe 102 and connected thereto. The inlet pipe 107 is connected to the inlet check valve 106, and the outlet pipe 105 is connected to the outlet check valve 104.

[0055] In use, the inlet pipe 107 can be inserted into the reagent bottle. Under the action of the inlet check valve 106 and the outlet check valve 104, pulling the piston 103 creates negative pressure, allowing liquid to enter the suction pipe 102 from the inlet pipe 107. Pushing the piston 103 allows the liquid to be discharged from the outlet pipe 105, facilitating the retrieval of high-risk reagents. Alternatively, in some embodiments, the outlet pipe 105 and the inlet pipe 107 in the suction mechanism can also be connected to the suction pipe 102 via a switchable three-way valve. By switching the passage of the three-way valve and controlling the reciprocating motion of the piston 103, high-risk reagents can be extracted and used.

[0056] like Figure 1 , 2As shown in Figure 6, in this embodiment, a threaded tube 108 communicating with the bottom of the mounting shell 101 is provided, and a screwed mounting tube 201 is provided on the threaded tube 108. A conical plug 204 is provided at the bottom of the mounting tube 201, and the water inlet tube 107 passes through the conical plug 204 and extends outward. The mounting tube 201 is installed by screwing, which facilitates the installation and disassembly of other parts. When using the extractor, after inserting the water inlet tube 107 into the mouth of the reagent bottle containing the high-risk reagent, the conical plug 204 can be inserted into the mouth of the reagent bottle to seal the mouth of the reagent bottle, so as to prevent the reagent from evaporating and leaking during the extraction and use of the high-risk reagent, which could cause harm to the staff.

[0057] like Figure 1 , 3 As shown in Figures 4 and 5, in this embodiment, two sets of clamping frames 404 are arranged opposite each other on both sides of the conical plug 204. A control mechanism connected to the two sets of clamping frames 404 is provided on the mounting tube 201, and the two sets of clamping frames 404 are driven to open and close by the control mechanism. The control mechanism includes a movable sleeve 301 that is raised and lowered along its axis and sleeved on the mounting tube 201. A first mounting frame 401 and a second mounting frame 501 are slidably arranged on the movable sleeve 301. The two sets of clamping frames 404 are respectively arranged at the bottom of the first mounting frame 401 and the second mounting frame 501. A first pressing plate 402 is fixedly arranged on the first mounting frame 401, and a second pressing plate 502 is fixedly arranged on the second mounting frame 501. A first elastic element 403 is provided between the first pressing plate 402 and the second pressing plate 502 and the movable sleeve 301.

[0058] Most reagent bottle mouths are equipped with an annular neck seat for mounting threaded reagent caps. The first mounting bracket 401 and the second mounting bracket 501 can slide relative to each other. When the first button 402 and the second button 502 are pressed, the first mounting bracket 401 and the second mounting bracket 501 slide relative to each other, thereby causing the two sets of clamping brackets 404 to open and close. This allows the two sets of clamping brackets 404 to be clamped onto the threads or neck seat of the reagent bottle mouth, thus fixing the extractor to reagent bottle mouths of different sizes. Under the action of the first elastic member 403, the two sets of clamping brackets 404 are closed to clamp the reagent bottle mouth.

[0059] like Figure 3 , 4As shown in Figure 5, in this embodiment, the first mounting bracket 401 and the second mounting bracket 501 are connected by a fixing mechanism to fix the relative positions of the first mounting bracket 401 and the second mounting bracket 501. The fixing mechanism includes a ratchet block 702 that can be raised and lowered and is disposed on the second mounting bracket 501. A ratchet rack 405 is disposed on the first mounting bracket 401, and the ratchet block 702 is engaged with the ratchet rack 405. A button 601 is disposed on the second button plate 502 in a direction perpendicular to the second button plate 502, and one end of the button 601 extends out of the second button plate 502. A second elastic element 604 is disposed on the button 601 and the movable sleeve 301. A drive assembly connected to the ratchet block 702 is disposed on the button 601. When the button 601 is pressed, the drive assembly drives the ratchet block 702 to rise and disengage from the ratchet rack 405.

[0060] The drive assembly includes a movable frame 602 on the button 601, the movable frame 602 is slidably mounted on the second mounting frame 501, a connecting seat 701 is provided on the ratchet block 702, the connecting seat 701 is provided with a slanted groove 703, and a drive column 603 is provided on the movable frame 602, the drive column 603 is slidably engaged in the slanted groove 703.

[0061] In the initial state, the button 601 is extended under the action of the second elastic element 604, which in turn causes the movable frame 602 to be in the extreme position, so that the drive column 603 is locked at the end of the inclined groove 703, and the ratchet block 702 is at the lowest position to be locked on the ratchet rack 405. The ratchet block 702 and the ratchet rack 405 cooperate to lock the first mounting frame 401 and the second mounting frame 501 in one direction, thereby preventing the two sets of clamping frames 404 from opening, so as to achieve more stable fixation. When it is necessary to control the opening of the two sets of clamping frames 404 to install or remove the extractor, press the first button 402 and the button 601 to compress the second elastic element 604, causing the movable frame 602 to slide and drive the drive column 603 to move in the inclined groove 703. Through the cooperation of the drive column 603 and the inclined groove 703, the ratchet block 702 moves upward and disengages from the ratchet rack 405. At this time, the finger contacts the second button 502, and by continuing to press the first button 402 and the second button 502, the first mounting frame 401 and the second mounting frame 501 can be controlled to slide relative to each other, thereby controlling the opening of the two sets of clamping frames 404, so that the extractor can be more stably fixed on the reagent bottle mouth, improving the safety of the device during use.

[0062] like Figure 1 , 3As shown in Figure 6, in this embodiment, the mounting tube 201 is provided with a lifting assembly connected to two sets of clamping frames 404. The lifting assembly drives the two sets of clamping frames 404 to rise. The lifting assembly includes a stop plate 202 disposed at the end of the mounting tube 201, and a third elastic member 302 is disposed between the second mounting frame 501 and the stop plate 202. Under the action of the third elastic member 302, the first mounting frame 401, the second mounting frame 501 and the movable sleeve 301 are subjected to an upward force, thereby causing the two sets of clamping frames 404 to have an upward tendency, so that the two sets of clamping frames 404 close with the conical plug 204, pressing the conical plug 204 downward, thereby effectively preventing the conical plug 204 from dislodging from the reagent bottle mouth, so as to stably install the conical plug 204.

[0063] like Figure 6 As shown, in this embodiment, the bottom of the stop plate 202 is circumferentially arranged with multiple sets of latches 203, and the conical plug 204 is circumferentially arranged with multiple sets of locking blocks 205, which are respectively locked into the multiple sets of latches 203. A sealing ring 206 is provided between the stop plate 202 and the conical plug 204.

[0064] The conical plug 204 can be rotated to disengage the locking block 205 from the latch 203, thereby disassembling the conical plug 204 and facilitating the replacement of damaged conical plugs 204. Conical plugs 204 of different sizes can also be replaced to improve the sealing effect. A sealing ring 206 is provided to seal the gap between the conical plug 204 and the stop plate 202, thereby further preventing gas leakage.

[0065] Specific usage and beneficial effects of the present invention:

[0066] When in use, the extractor can be controlled by pressing the first button 402 and the second button 502 to slide the first mounting bracket 401 and the second mounting bracket 501 relative to each other, so that the two sets of clamping brackets 404 open and close. After the two sets of clamping brackets 404 are opened, the conical plug 204 and the water inlet pipe 107 are inserted into the mouth of the high-risk reagent bottle to seal the mouth of the high-risk reagent bottle. Under the action of the first elastic element 403, the two sets of clamping brackets 404 are controlled to close, so that the two sets of clamping brackets 404 are clamped on the reagent bottle. The extractor is installed on the thread or neck seat, and under the action of the third elastic element 302, the two sets of clamping frames 404 in the clamping state rise, so that the conical plug 204 has a downward force to effectively seal the mouth of the reagent bottle. The high-risk reagent can be extracted and used through the liquid extraction mechanism. The extractor can quickly seal and fix the mouth of reagent bottles of different sizes, thereby effectively preventing the volatilization of high-risk reagents from causing harm to the health of workers during use.

[0067] During the closing process of the two sets of clamping frames 404 in the extractor, the first mounting frame 401 and the second mounting frame 501 move in opposite directions, which allows the ratchet block 702 to slide along the ratchet rack 405. In turn, the ratchet block 702 and the ratchet rack 405 cooperate to lock the first mounting frame 401 and the second mounting frame 501 in one direction, effectively preventing the first mounting frame 401 and the second mounting frame 501 from sliding in opposite directions during use and causing the two sets of clamping frames 404 to open. This effectively fixes the mouth of the high-risk reagent bottle and improves the reliability and safety of the device during use. When the device needs to be disassembled, the button 601 and the first button plate 402 can be pressed. As the button 601 moves in the second button plate 502, it compresses the second elastic frame and drives the movable frame 602 to slide relative to the second mounting frame 501, thereby driving the drive column 603 to move. During the movement, the drive column 603, through its cooperation with the inclined groove 703, drives the ratchet block 702 to rise and disengage from the ratchet rack 405, thereby releasing the position lock of the first mounting frame 401 and the second mounting frame 501. Then, by pressing the first button plate 402 and the second button plate 502, the two sets of clamping frames 404 can be opened to disassemble the extractor, which improves the convenience of using the extractor.

[0068] The foregoing has shown and described the basic principles and main features of the present invention and its advantages. It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments.
