Description

Technical Field

[0001] The utility model belongs to the technical field of tracheal intubation auxiliary equipment, in particular to a medical mercury leakage treatment device. Background Art

[0002] Mercury, commonly known as quicksilver, is a chemical element and the only common metal that exists in liquid form at room temperature and pressure. Mercury is a shiny, silvery-white, heavy liquid with stable chemical properties, insoluble in both acids and alkalis. Mercury evaporates at room temperature, and its vapor and compounds are highly toxic. Currently, mercury-containing medical devices, such as mercury thermometers and sphygmomanometers, are still widely used in hospitals in my country. Breakage of these devices, leading to mercury leaks, is a common occurrence in clinical nursing. Prompt removal of the mercury is crucial to prevent potential harm to patients and medical staff.

[0003] For example, Patent No. CN205023220U discloses a mercury collection device comprising a tube body, a top cover, and a bottom cover. The top of the tube body is provided with an elastic bladder, and the bottom of the tube body is formed into a slender tubular shape. The top cover is removably provided at the top of the tube body to surround the elastic bladder, and the bottom cover is removably provided at the bottom of the tube body to surround the bottom of the slender tubular shape. In the event of a mercury leak, the mercury collection device of the present invention releases the bladder by squeezing it, drawing mercury beads into the tube body. Small mercury beads can be covered with sulfur powder to form chemically stable mercuric sulfide, which can then be wiped clean with disinfectant wipes containing available chlorine (or iodine tincture to form chemically stable mercuric iodide).

[0004] During the use of this device, it was found that the technology has the following problems. The device squeezes the leather bag and then releases it to form a negative pressure on the tube body to absorb the mercury beads into the interior. However, this method requires that all the mercury is absorbed before the leather bag is completely released. Otherwise, the tube body needs to be inverted and the leather bag needs to be squeezed again to form a negative pressure to reabsorb the mercury. During this process, the mercury previously absorbed may be ejected from the bottom end of the slender tube, causing secondary pollution. Therefore, in order to solve this problem, it is necessary to optimize the design of the product and propose a medical mercury leakage treatment device. Utility Model Content

[0007] In a preferred embodiment, the top of the recovery cylinder is provided with a thread groove adapted to the thread of the bottom of the cover, and a rubber sealing ring is provided at the connection position between the top of the recovery cylinder and the cover.

[0008] In a preferred embodiment, a magnifying glass is fixedly mounted on the left side of the top of the forward extension rod, and the top of the magnifying glass is tilted toward the suction nozzle.

[0009] In a preferred embodiment, a No. 1 slide groove adapted to the skateboard is opened inside the top block, the top of the skateboard is fixedly connected to the No. 1 slide groove through a No. 1 spring, and a movable groove adapted to the extrusion block is opened on the top of the forward rod, and the extrusion block is arranged opposite to the protrusion.

[0010] In a preferred embodiment, a filter plate and a check valve are respectively provided on the soft air pipe, the filter plate is located below the check valve, an exhaust pipe is fixedly connected to the top front side of the piston cylinder, and a check valve is also provided at the connection position between the exhaust pipe and the piston cylinder. The check valve on the soft air pipe allows air to flow toward the piston cylinder, and the check valve on the exhaust pipe allows air to flow away from the piston cylinder.

[0011] In a preferred embodiment, sulfur powder is placed inside the recovery cylinder, a baffle is fixedly installed on the inner wall of the recovery cylinder below the soft air tube, the bottom end of the soft suction tube is located below the inner cavity of the recovery cylinder, and the bottom end of the soft air tube is located above the inner cavity of the recovery cylinder.

[0012] In a preferred embodiment, a No. 2 slide groove adapted to the slide column is opened in the handle, and the slide column is fixedly connected to the No. 2 slide groove through a No. 2 spring sleeved on the outer periphery, and a movable groove adapted to the button is opened on the left side of the handle.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0014] 1. In the present application, through the above design, before using the present device to recover the leaked mercury, first put sulfur powder in the recovery cylinder, then rotate the recovery cylinder toward the bottom of the cover to seal it. At this time, since the squeezing block in the top block is rebounded by the No. 1 spring on the top of the slide, the squeezing block cooperates with the convex block to firmly squeeze the hose from the outer wall and seal it, so that the hose, soft straw, recovery cylinder, soft air pipe and piston cylinder that are now interconnected form a closed state. Then, the rod at the outer end of the piston cylinder is pulled and pushed cyclically to stop the stopper on the soft air pipe. The return valve and the check valve on the exhaust pipe only allow one-way air flow, so that the piston cylinder continuously extracts the air in the recovery cylinder and discharges it through the exhaust pipe, thereby creating a negative pressure state in the recovery cylinder to prepare for the subsequent absorption of mercury. When the negative pressure state is formed in the recovery cylinder, the medical staff holds the handle and uses a magnifying glass to search for scattered mercury and aligns the found mercury with the suction nozzle. During this process, since the recovery cylinder and the connecting rod are connected by a ball head, the recovery cylinder will remain vertical to the horizontal plane at a certain tilt angle, and the suction nozzle is aligned with the horizontal plane. After the mercury is released, the medical staff slightly presses the button. At this time, the button compresses the second spring to the right through the sliding column, which in turn causes the sliding column to compress the airbag disc, so that the gas in the airbag disc is sent to the airbag ring on the outer periphery of the extrusion block at the bottom of the slide through the connecting tube, thereby causing the airbag ring to expand and lift the slide to drive the extrusion block to move upward. At this time, the rubber hose loses the contact with the extrusion block and is released from the seal, so that the rubber hose is connected to the suction nozzle at the left end. At this time, the recovery cylinder with negative pressure inside generates suction on the suction nozzle through the soft straw and the rubber hose, thereby sucking the mercury into the recovery cylinder. When the suction is completed in the cylinder, release the button, and the extrusion block will be re-connected to the hose based on the same principle to retain the remaining negative pressure in the recovery cylinder to cope with the adsorption work at the next mercury leakage point. Of course, after the negative pressure in the recovery cylinder is completely released, it is only necessary to push and pull the rod again to re-form the negative pressure in the recovery cylinder to cope with the mercury absorption work at multiple locations. At the same time, the mercury sucked into the recovery cylinder here will mix with the sulfur powder in the recovery cylinder to react and produce mercury sulfide, thereby effectively preventing the leaked mercury from causing harm to medical staff and patients in the surrounding environment.

A top block 9 is fixedly installed on the top of the forward rod 6. A hose 10 is installed inside the forward rod 6, and its two ends are connected to the suction nozzle 7 and the soft straw 5 respectively. A convex block 11 is fixedly installed at the bottom of the forward rod 6 to abut against the hose 10. A slide plate 12 with a spring No. 1 is installed on the top of the top block 9. The bottom of the slide plate 12 is fixedly installed with an extrusion block 13 abutting against the top of the hose 10. The interior of the top block 9 is provided with a spring No. 1. The slide 12 is adapted to the No. 1 slide, the top of the slide 12 is fixedly connected to the No. 1 slide by a spring, the top of the forward rod 6 is provided with a movable groove adapted to the extrusion block 13, the extrusion block 13 is arranged opposite to the convex block 11, the right end of the gun barrel 1 is fixedly installed with a piston cylinder 17 whose inner cavity is connected to the soft air pipe 14, and the right end of the piston cylinder 17 is plugged with a plug 18 fixed to the piston inside the piston cylinder 17. The soft air pipe 14 is respectively provided with a filter plate 15 and a check valve 16, the filter plate 15 is located below the check valve 16, and the piston cylinder 17 is fixed with a plug 18 fixed to the piston inside the piston cylinder 17. An exhaust pipe 19 is fixedly connected to the front side of the top, and a check valve 16 is also provided at the connection position between the exhaust pipe 19 and the piston cylinder 17. The check valve 16 on the soft air pipe 14 allows air to flow toward the piston cylinder 17, and the check valve 16 on the exhaust pipe 19 allows air to flow away from the piston cylinder 17. Sulfur powder 21 is placed inside the recovery cylinder 4, and a baffle 20 is fixedly installed on the inner wall of the recovery cylinder 4 below the soft air pipe 14. The bottom end of the soft suction pipe 5 is located below the inner cavity of the recovery cylinder 4, and the bottom end of the soft air pipe 14 is located above the inner cavity of the recovery cylinder 4.

[0023] Through the above design, before using the present device to recover the leaked mercury, first put sulfur powder 21 into the recovery cylinder 4, and then rotate the recovery cylinder 4 to the bottom of the cover 3 to seal it. At this time, since the squeezing block 13 in the top block 9 is rebounded and abutted by the No. 1 spring on the top of the slide 12, the squeezing block 13 cooperates with the protrusion 11 to firmly squeeze and seal the hose 10 from the outer wall, so that the hose 10, soft suction pipe 5, recovery cylinder 4, soft air pipe 14 and piston cylinder 17 that are interconnected at this moment form a closed state. Then, the insertion rod 18 at the outer end of the piston cylinder 17 is cyclically pulled and pushed. Under the action of the check valve 16 on the soft air pipe 14 and the check valve 16 on the exhaust pipe 19 that only allow one-way air circulation, the piston cylinder 17 continuously extracts the air in the recovery cylinder 4 and discharges it through the exhaust pipe 19, thereby creating a negative pressure state in the recovery cylinder 4 to prepare for the subsequent absorption of mercury.

[0024] Reference Figure 1 、 2 , 3, 4. A handle 22 is fixedly installed on the right side of the bottom of the gun barrel 1, and an airbag disc 23 is fixedly installed on the right side of the handle 22. The bottom of the slide plate 12 is located on the outer periphery of the extrusion block 13 and is sleeved with an airbag ring 24. The outer wall of the airbag disc 23 is fixedly connected with a connecting tube 25, and the upper end of the connecting tube 25 is communicated with the airbag ring 24. A sliding post 26 with a No. 2 spring sleeved on the outer periphery is slidably installed on the inner left side of the handle 22, and a button 27 is fixedly installed on the left side of the sliding post 26. A No. 2 slide groove compatible with the slide post 26 is provided in the handle 22, and the slide post 26 is fixedly connected to the No. 2 slide groove through the No. 2 spring sleeved on the outer periphery. A movable groove compatible with the button 27 is provided on the left side of the handle 22.

[0025] Through the above design, when a negative pressure state is formed in the recovery tube 4, the medical staff holds the handle 22 and uses the magnifying glass 8 to search for scattered mercury and aligns the found mercury with the suction nozzle 7. During this process, since the recovery tube 4 and the connecting rod 2 are connected by a ball head, the recovery tube 4 will remain vertical to the horizontal plane at a certain tilt angle. After the suction nozzle 7 is aligned with the mercury, the medical staff slightly presses the button 27. At this time, the button 27 compresses the second spring through the sliding column 26 to move to the right, thereby causing the sliding column 26 to compress the airbag disc 23, so that the gas in the airbag disc 23 is sent to the airbag ring 24 on the outer periphery of the extrusion block 13 at the bottom of the slide 12 through the connecting pipe 25, thereby causing the airbag ring 24 to expand and lift the slide 12 to drive the extrusion block 13 to move upward. At this time, the hose 10 loses the abutment of the extrusion block 13. , the seal is released, so that the rubber tube 10 is connected to the suction nozzle 7 at the left end. At this moment, the recovery cylinder 4 with a negative pressure inside generates suction on the suction nozzle 7 through the soft suction tube 5 and the rubber tube 10, thereby sucking the mercury into the recovery cylinder 4. After the suction is completed, the button 27 is released. The squeezing block 13 based on the same principle will be re-connected to the rubber tube 10 to retain the remaining negative pressure in the recovery cylinder 4 to cope with the adsorption work at the next mercury leakage site. Of course, after the negative pressure in the recovery cylinder 4 is completely released, it is only necessary to push and pull the insertion rod 18 again to re-generate negative pressure in the recovery cylinder 4 to cope with the mercury absorption work at multiple locations. The mercury sucked into the recovery cylinder 4 here will mix and react with the sulfur powder 21 in the recovery cylinder 4 to produce mercury sulfide, thereby effectively preventing the leaked mercury from causing harm to medical staff and patients in the surrounding environment.

[0026] The implementation principle of the embodiment of this application is:

[0027] First, before using the present device to recover the leaked mercury, first put sulfur powder 21 into the recovery cylinder 4, and then rotate the recovery cylinder 4 to the bottom of the cover 3 to tighten the seal. At this time, since the extrusion block 13 in the top block 9 is rebounded and abutted by the No. 1 spring on the top of the slide 12, the extrusion block 13 cooperates with the protrusion 11 to firmly squeeze and seal the hose 10 from the outer wall, so that the hose 10, soft suction pipe 5, recovery cylinder 4, soft air pipe 14 and piston cylinder 17 that are now interconnected form a closed state. Then, the rod 18 at the outer end of the piston cylinder 17 is cyclically pulled and pushed. Under the action of the check valve 16 on the soft air pipe 14 and the check valve 16 on the exhaust pipe 19 that only allow one-way air circulation, the piston cylinder 17 continuously extracts the air in the recovery cylinder 4 and discharges it through the exhaust pipe 19, thereby creating a negative pressure state in the recovery cylinder 4 to prepare for the subsequent absorption of mercury.

[0028] When a negative pressure state is formed in the recovery cylinder 4, the medical staff holds the handle 22 and uses the magnifying glass 8 to search for scattered mercury and aligns the found mercury with the suction nozzle 7. During this process, since the recovery cylinder 4 and the connecting rod 2 are connected by a ball head, the recovery cylinder 4 will remain vertical to the horizontal plane at a certain tilt angle. After the suction nozzle 7 is aligned with the mercury, the medical staff slightly presses the button 27. At this time, the button 27 compresses the second spring to the right through the sliding column 26, thereby causing the sliding column 26 to compress the airbag disc 23, so that the gas in the airbag disc 23 is sent to the airbag ring 24 on the outer periphery of the extrusion block 13 at the bottom of the slide 12 through the connecting pipe 25, thereby causing the airbag ring 24 to expand and lift the slide 12 to drive the extrusion block 13 to move upward. At this time, the hose 10 loses the abutment of the extrusion block 13 and is released. The seal is formed so that the rubber tube 10 is connected to the suction nozzle 7 at the left end. At this moment, the recovery cylinder 4 with a negative pressure inside generates suction on the suction nozzle 7 through the soft suction tube 5 and the rubber tube 10, thereby sucking the mercury into the recovery cylinder 4. After the suction is completed, the button 27 is released. The squeezing block 13 based on the same principle will be re-connected to the rubber tube 10 to retain the remaining negative pressure in the recovery cylinder 4 to cope with the adsorption work at the next mercury leakage point. Of course, after the negative pressure in the recovery cylinder 4 is completely released, it is only necessary to push and pull the insertion rod 18 again to re-generate negative pressure in the recovery cylinder 4 to cope with the mercury absorption work at multiple locations. The mercury sucked into the recovery cylinder 4 here will mix and react with the sulfur powder 21 in the recovery cylinder 4 to produce mercury sulfide, thereby effectively preventing the leaked mercury from causing harm to medical staff and patients in the surrounding environment.
