[0040] See also Figure 1-Figure 15As shown, the present invention provides a double-tube interconnected nasal secretion cleaning and collecting device, comprising a liquid supply bottle 100 in an expanded state, a liquid collecting bottle 110 and a liquid passing tube 200 correspondingly arranged above the two, the liquid supply bottle 100 and the liquid collecting bottle 110 are made of PP plastic to form a corrugated folding cylinder, so that they can automatically adjust their size under pressure and gravity; the liquid passing tube 200 is made of PP plastic to form a tube, so that it can be bent and used to align with nostrils with different spacings; a liquid passing box 300 is arranged between the liquid supply bottle 100, the liquid collecting bottle and a pair of liquid passing tubes 200, and a washing and collecting part 400 is arranged inside the liquid passing box 300 to separate its cavity to form reverse liquid flow; the liquid inside the liquid supply bottle 100 is lifted by the washing and collecting part 400 into the liquid passing tube 200 on the right to wash the nasal cavity and then transferred to the liquid passing tube 200 on the left, and then collected by the liquid collecting bottle 110; thereby providing washing for the nasal cavity while circulating and recovering the nasal secretions.

[0041] Specifically, a gas nozzle 320 is arranged at the left side of the top of the liquid-passing box 300, and a one-way valve is installed in the gas nozzle 320 to allow external gas to enter but not exit. The washing and collecting part 400 includes a bearing 410 arranged in the middle of the liquid-passing box 300 to divide the interior into two cylindrical cavities, a liquid-passing valve 420 slidably sleeved in the right half of the liquid-passing box 300, a recovery valve 430 slidably sleeved in the left half of the liquid-passing box 300, and a recovery valve 430 arranged in the bearing 410 for controlling the liquid-passing valve 420 and the recovery valve 430. The control group 440 of the retracting valve 430 moves up and down in opposite directions; when the retracting valve 430 moves downward from the top of the liquid box 300, the outside air can be sucked in through the air nozzle 320, and the secretions and flushing liquid in the nasal cavity are absorbed into the left half of the liquid box 300, and then flow into the liquid collection bottle 110; when the retracting valve 430 moves upward, the air can be squeezed out from the liquid tube 200 into the nasal cavity to supplement oxygen for breathing; the liquid box 300 is made of transparent material, so that the internal situation can be seen clearly;

[0042] The liquid-passing valve 420 is disc-shaped and has a valve opening 422 at its center. The inner wall of the valve opening 422 is turned up and connected to a valve cover 423. A one-way tube 120 is sleeved inside the top port of the liquid supply bottle 100, and a one-way valve is sleeved inside the upper port of the one-way tube 120, so that only the liquid in the liquid supply bottle 100 can flow; that is, the liquid-passing valve 420 moves upward from the middle of the liquid-passing box 300 to generate negative pressure and suck the flushing liquid in the liquid supply bottle 100 into the liquid-passing box 300 along the one-way tube 120. When the liquid-passing valve 420 falls back, the valve cover 423 is pushed open by the liquid and the liquid is transferred to the top of the liquid-passing valve 420. After several reciprocating movements, the liquid can fill the right half of the liquid-passing box 300. When the pressing control group 440 controls the liquid-passing valve 420 to rebound and reset, the liquid can be squeezed and sprayed into the liquid-passing tube 200 and the nasal cavity to wash the nasal secretions.

[0043] The recovery valve 430 is in the shape of a ring and a sealing sleeve 432 is tightly fitted on the inner wall of its center hole. A straight seam is opened on the central axis of the sealing sleeve 432. The sealing sleeve 432 is made of silicone so that the straight seam is sealed in a natural state; a drainage tube 130 is sleeved above the top port of the liquid collecting bottle 110 and is plugged into the straight seam of the sealing sleeve 432. When the recovery valve 430 falls back from the top of the liquid passing box 300 to the middle thereof, the straight seam is fitted with the top end of the drainage tube 130, thereby draining the inhaled nasal secretions through the drainage tube 130 to flow to the liquid collecting bottle 110.

[0044] Specifically, a countersunk hole 411 is provided at the center of the top surface of the carrier 410, and the countersunk hole 411 extends to the bottom of the carrier 410 and does not penetrate through the bottom. The control group 440 includes a piston 441 slidably sleeved with the countersunk hole 411, an elastic rib 443 for suspending the piston 441 in the middle of the countersunk hole 411, and a button 442 slidably connected to the lower half of the front side of the carrier 410 and magnetically attracting the piston 441 to move synchronously; a round block tightly engaged with the upper end of the elastic rib 443 is bonded to the upper end of the countersunk hole 411, the piston 441 is composed of an iron block and a rubber skin wrapped outside, the button 442 does not extend into the countersunk hole 411, and a neodymium magnet is embedded in the button 442 near the piston 441, so that the piston 441 is magnetically attracted by its strong magnetic force, so that the piston 441 can be driven to move by pressing the button 442 from the outside;

[0045] The left and right sides of the carrier 410 are vertically provided with slide grooves 412, and the top side wall of the slide groove 412 on the right and the bottom side wall of the slide groove 412 on the left are provided with plug holes 413, the plug holes 413 are connected with the countersunk holes 411, and the outsides of the two plug holes 413 are provided with conduits 450, the countersunk holes 411 and the two conduits 450 are filled with liquid, so that the liquid in the countersunk holes 411 and the conduits 450 are divided into two parts by the piston; pressing the button 442 squeezes the liquid in the lower half of the countersunk holes 411 to lift the recovery valve 430 to the top of the liquid box 300, so as to suck the secretions when it falls back; by designing the inner diameter of the air nozzle 320 to be smaller than the inner diameter of the liquid tube 200, the negative pressure suction generated when the recovery valve 430 falls back instantly can suck a large amount of secretions.

[0046] Furthermore, a valve tube 421 is vertically provided on one side of the liquid-passing valve 420 and is slidably engaged with the slide groove 412. The upper end of the valve tube 421 is open and is inserted and slidably engaged with the catheter 450 located above; a sleeve 431 is vertically provided on one side of the recovery valve 430 and is slidably engaged with the slide groove 412. The lower end of the sleeve 431 is open and is slidably engaged with the catheter 450 located below, and the inner cavity volume of the catheter 450 is at most equal to half of the volume of the counterbore 411; so that half of the liquid in the counterbore 411 is squeezed into the catheter 450 and filled into the sleeve 431, so that the recovery valve 430 is lifted to the top of the liquid-passing box 300; the push button 442 drives the piston 441 and the liquid-passing valve 420 to descend synchronously, and drives the recovery valve 430 to rise, forming a state ready for liquid extraction and secretion suction.

[0047] Furthermore, a tube head 451 is connected to the side wall of one end of the catheter 450, and the tube head 451 is tightly plugged into the socket 413. A connecting rod 4421 is provided in the middle inner side of the button 442, which is bent and extends to the top side wall of the liquid valve 420. The upper end of the connecting rod 4421 is fixedly connected to the side wall of the valve tube 421, that is, the pressing force of the button 442 is transmitted through the connecting rod 4421. After the button 442 is released, the rebound force of the elastic rib 443 and the negative pressure state formed in the upper half of the counterbore 411 cause the button 442 to instantly bounce up and reset, thereby forming a state in which the liquid valve 420 is quickly driven to move upward to supply liquid, thereby achieving the effect of flushing nasal secretions.

[0048] Specifically, a limiting groove 414 is opened on the vertical center line of the front side surface of the carrier 410 and is engaged with the connecting rod 4421 to guide the button 442 to slide up and down; a through groove 415 is opened on one side wall of the slide groove 412 facing the right side, and the through groove 415 is connected with the upper half of the limiting groove 414, and the upper horizontal bending section of the connecting rod 4421 is engaged with the through groove 415 and slides, so that the button 442 smoothly drives the liquid valve 420 to move accordingly; the limiting groove 414 and the through groove 415 are not connected with the countersunk hole 411, thereby ensuring the sealing of the inside of the countersunk hole 411.

[0049] Furthermore, the liquid passage box 300 is a rectangular box structure with rounded corners on both sides and a liquid passage nozzle 310 is embedded in the center of the upper and lower circles. The lower end of the liquid passage tube 200 is provided with a connector 201 that is sleeved and matched with the liquid passage nozzle 310. A through hole 301 that is plugged and matched with the carrier 410 is provided in the middle of the top surface of the liquid passage box 300. A through groove 302 that is slidably engaged with the connecting rod 4421 is provided in the lower half of the front side surface of the liquid passage box 300, so that the button 442 is not interfered when it moves downward; a nasal plug head 202 is sleeved on the upper port of the liquid passage tube 200, and the nasal plug head 202 is in the shape of a spherical shell with openings on the upper and lower sides to block the nostrils.

[0050] Specifically, a distance adjustment group 210 is provided between the tops of the two liquid-passing pipes 200. The distance adjustment group 210 includes a pair of connecting sleeves 211 and a rotating sleeve 212 sleeved between the pair of connecting sleeves 211. The connecting sleeves 211 are sleeved and matched with the liquid-passing pipes 200.

[0051] A connecting tube 2111 is provided on the side wall of the connecting sleeve 211, and a thread is provided on the inner wall of the connecting tube 2111. A screw rod 2121 threadedly connected to the connecting tube 2111 is provided on the central axis of the rotating sleeve 212. A spring 2122 is provided inside the rotating sleeve 212, and the outer end of the spring 2122 is bonded to the end surface of the connecting tube 2111. By rotating the rotating sleeve 212 and utilizing the threaded movement of the screw rod 2121 and the connecting tube 2111, a pair of connecting sleeves 211 can be moved closer or farther, thereby adjusting the top spacing of a pair of liquid passage tubes 200 to adapt to different nose spacings.

[0052] Furthermore, a cover 140 is tightly fitted inside the top ports of the liquid supply bottle 100 and the liquid collection bottle 110, and the two covers 140 are correspondingly fitted with the upper end of the one-way tube 120 and the lower end of the drainage tube 130. A non-slip pad 330 is bonded to the rounded outer side surface of the liquid box 300, so that the user can grasp the operation button 442 of the liquid box 300 to clean the nasal cavity and collect secretions more stably and easily.

[0053] When using the double-tube interconnected nasal secretion cleaning and collecting device of the present invention, first fill the liquid supply bottle 100 with an appropriate amount of flushing liquid, and install it and the liquid collection bottle to the bottom of the liquid box 300, then operate the distance adjustment group 210 to adjust the distance between the upper ends of a pair of liquid tubes 200, so that the nasal plug head 202 can be inserted into the two nostrils at the same time; then repeatedly press the button 442 intermittently several times, so that the liquid valve 420 moves up and down in the right half cavity of the liquid box 300 to suck the flushing liquid into it until it is full; press the button 442 again to drive the liquid valve 420 to drop to the middle of the right half cavity of the liquid box 300, and at the same time drive the piston 441 to squeeze the liquid in the lower half cavity of the countersunk hole 411 to lift the recovery valve 430 to the top of the left half cavity of the liquid box 300, at this time A pre-order state of extracting liquid and sucking secretions is formed. After releasing the button 442, the rebound force of the elastic rib 443 and the negative pressure state formed in the upper half of the sink hole 411 cause the button 442 to instantly bounce up and reset, thereby forming a state of quickly driving the liquid valve 420 to move up to supply liquid, thereby achieving the effect of flushing the nasal secretions; at the same time, the recovery valve 430 is pulled back by the negative pressure due to the reflux of liquid into the sink hole 411, thereby sucking the secretions in the nasal cavity, and when the recovery valve 430 falls back from the top of the liquid box 300 to the middle thereof, the straight seam of the sealing sleeve 432 is connected with the top end of the drainage tube 130, thereby draining the sucked nasal secretions through the drainage tube 130 to the liquid collection bottle 110, thereby achieving the effect of flushing the nasal cavity and recovering the secretions at the same time.
