Abstract
Description
Technical Field
[0001] This utility model relates to the field of oxygen supply pipe technology, and in particular to an oxygen supply pipe. Background Technology
[0002] An oxygen supply tube is a piping system specifically designed for medical use to deliver high-purity oxygen to patients. In the medical field, oxygen supply tubes are an indispensable part of respiratory therapy, surgery, emergency care, and rehabilitation. For better oxygen delivery, the tube can be inserted into the glottis.
[0003] However, secretions can be present at the glottis, which can easily clog the oxygen supply tube. While the secretions at the glottis can be extracted, the oxygen delivered to the glottis will also be drawn out during the extraction process. This makes it impossible to extract the secretions during the oxygen delivery process. Utility Model Content
[0004] The purpose of this invention is to address the problem mentioned in the background art that when extracting secretions, the oxygen delivered to the glottis is simultaneously drawn out, and to propose an oxygen supply tube that can periodically deliver oxygen and extract secretions.
[0005] The technical solution of this utility model: an oxygen supply tube, comprising a multi-lumen tube, and further comprising:
[0006] Multiple oxygen delivery holes and one adsorption hole are provided on a multi-lumen tube. The multiple oxygen delivery holes are fixedly connected to a delivery tube, and a negative pressure tube is fixedly installed on the adsorption hole.
[0007] An installation box is fixed to the delivery pipe and the negative pressure pipe. An oxygen connection pipe and a negative pressure connection pipe are fixedly installed on the installation box. The oxygen connection pipe is connected to the delivery pipe, and the negative pressure connection pipe is connected to the negative pressure pipe.
[0008] The shut-off mechanism is installed inside the installation box and periodically seals the oxygen connection pipe and the negative pressure connection pipe.
[0009] Optionally, multiple diversion tubes are fixedly installed on the multi-chamber tube, and the multiple diversion tubes correspond one-to-one with the multiple oxygen delivery holes and are in a coaxial position. A connector is fixedly installed on the multiple diversion tubes, and the delivery tube is fixedly installed on the connector.
[0010] Optionally, the shut-off mechanism includes a first shut-off pipe and a second shut-off pipe fixedly installed in the mounting box. The first shut-off pipe is connected to the oxygen connection pipe and the delivery pipe, and the second shut-off pipe is connected to the negative pressure connection pipe and the negative pressure pipe. A first valve core is rotatably installed in the first shut-off pipe, and a second valve core is rotatably installed in the second shut-off pipe. The first valve core and the second valve core are perpendicular to each other. A drive assembly for driving the first valve core and the second valve core to rotate synchronously is installed in the mounting box.
[0011] Optionally, the drive assembly includes a first gear and a second gear rotating within the mounting box, a first support rod fixedly mounted within the mounting box, and a rack slidably mounted on the first support rod. Both the first gear and the second gear mesh with the rack for transmission. The first gear is coaxially and fixedly connected to the first valve core, and the second gear is coaxially and fixedly connected to the second valve core. A push rod motor is fixedly mounted on the mounting box, and the output shaft of the push rod motor is fixedly connected to the rack.
[0012] Optionally, one end of the multi-chamber tube is provided with multiple air holes, which are connected to the oxygen delivery holes. The inner wall of the adsorption hole is provided with multiple cleaning holes, which correspond one-to-one with the multiple air holes and are coaxially arranged.
[0013] Optionally, a sealing mechanism is installed inside the adsorption hole, which seals the cleaning hole during oxygen delivery.
[0014] Optionally, the sealing mechanism includes a connecting piece fixedly installed at one end of the multi-cavity tube, a second support rod fixedly installed on the connecting piece, and a sealing piece fixedly installed on the second support rod. The sealing piece is provided with a plurality of first cavity holes and second cavity holes, which correspond one-to-one and are coaxially arranged. The inner diameter of the first cavity hole is smaller than that of the second cavity hole. An elastic pad is fixedly installed on the second cavity hole, and a conical block is fixedly installed on the elastic pad. The elastic pad is provided with a plurality of conveying holes.
[0015] Compared with the prior art, the present invention has the following beneficial technical effects:
[0016] By periodically activating the push rod motor, the oxygen and negative pressure connection tubes can be periodically blocked, allowing for the periodic delivery of oxygen and absorption of secretions. This prevents the adsorption orifice from drawing out oxygen delivered to the glottis, thus avoiding reduced oxygen flow and ensuring the effectiveness of oxygen therapy.
[0017] Furthermore, when oxygen is delivered, the conical block will seal the first cavity orifice, preventing oxygen from entering the adsorption orifice through the cleaning orifice, thus preventing a reduction in oxygen flow and ensuring that all oxygen can enter the glottis through the vent. When the vent is blocked by secretions at the glottis, the conical block will be unable to seal the first cavity orifice. At this time, the suction force generated by the adsorption orifice will act on the cleaning orifice through the first cavity orifice, thereby causing the cleaning orifice to clean the secretions adhering to the vent. This allows for the removal of secretions adhering to the vent and cleaning of the vent, ensuring the flow of oxygen during delivery. Secretions at the glottis can be cleaned without repeated insertion and removal, avoiding the discomfort caused to the patient by repeated insertion and removal. When the adsorption orifice no longer generates suction, the elastic pad itself will cause the conical block to seal the first cavity orifice again. Attached Figure Description

[0028] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0029] Example
[0030] like Figure 1-3 As shown, the present invention proposes an oxygen supply tube, including a multi-lumen tube 1, and further including multiple oxygen delivery holes 2 and an adsorption hole 7 disposed on the multi-lumen tube 1. One end of the multi-lumen tube 1 is provided with multiple air holes 201, which are connected to the oxygen delivery holes 2. In use, the end with the air holes 201 is directly inserted into the glottis position, so as to provide more oxygen.
[0031] like Figure 1-3 As shown, multiple oxygen delivery holes 2 are fixedly connected to a delivery pipe 302, and a negative pressure pipe 4 is fixedly installed on the adsorption hole 7. Multiple branch pipes 3 are fixedly installed on the multi-chamber tube 1, each corresponding to one of the multiple oxygen delivery holes 2 and coaxially positioned. A connector 301 is fixedly installed on each of the branch pipes 3, and the delivery pipe 302 is fixedly installed on the connector 301. An installation box 5 is fixed to the delivery pipe 302 and the negative pressure pipe 4. An oxygen connecting pipe 303 and a negative pressure connecting pipe 401 are fixedly installed on the installation box 5. The oxygen connecting pipe 303 is connected to the delivery pipe 302, and the negative pressure connecting pipe 401 is connected to the negative pressure pipe 4. The oxygen connecting pipe 303 is connected to an oxygen generator, which delivers oxygen to the inside of the oxygen connecting pipe 303. The oxygen then enters the oxygen delivery hole 2 through the delivery pipe 302 and the branch pipes 3, and finally, the oxygen is directly delivered to the glottis through the air hole 201, resulting in a more sufficient oxygen supply. However, there are secretions at the glottis, which easily stick to the pore 201. To block the pore 201, the negative pressure connecting tube 401 is connected to a medical negative pressure pump. The medical negative pressure pump applies negative pressure to the negative pressure connecting tube 401, thereby creating suction force on the external environment through the adsorption hole 7. This allows the secretions at the glottis to be removed through the adsorption hole 7, ensuring the flowability of the pore 201.
[0032] like Figure 4-5As shown, a shut-off mechanism is installed inside the mounting box 5. This mechanism periodically seals the oxygen connection pipe 303 and the negative pressure connection pipe 401. The shut-off mechanism includes a first shut-off pipe 501 and a second shut-off pipe 502 fixedly installed inside the mounting box 5. The first shut-off pipe 501 is connected to the oxygen connection pipe 303 and the delivery pipe 302, while the second shut-off pipe 502 is connected to the negative pressure connection pipe 401 and the negative pressure pipe 4. A first valve core 503 is rotatably installed inside the first shut-off pipe 501, and a second valve core 504 is rotatably installed inside the second shut-off pipe 502. The first valve core 503 and the second valve core 504 are perpendicular to each other. A drive assembly is installed inside the mounting box 5 to drive the first valve core 503 and the second valve core 504 to rotate synchronously. When it is necessary to clean the secretions at the glottis, the first valve core 503 and the second valve core 504 are rotated periodically. Since the first valve core 503 and the second valve core 504 are perpendicular to each other, when the first valve core 503 blocks the first stop tube 501, the second valve core 504 will not block the second stop tube 502. This means that only one of the first stop tube 501 and the second stop tube 502 can be in a connected state. When the first stop tube 501 is open, oxygen can be delivered normally. When the first stop tube 501 is blocked, oxygen cannot be delivered, but negative pressure can be applied to the adsorption hole 7. This prevents oxygen delivery and secretion aspiration from happening simultaneously, but allows them to work alternately. This prevents the adsorption hole 7 from drawing out the oxygen delivered to the glottis, avoiding the problem of reduced oxygen flow and affecting the oxygen therapy effect.
[0033] The drive assembly includes a first gear 505 and a second gear 506 rotating within the mounting box 5, a first support rod 507 fixedly mounted within the mounting box 5, and a rack 508 slidably mounted on the first support rod 507. Both the first gear 505 and the second gear 506 mesh with the rack 508 for transmission. The first gear 505 is coaxially and fixedly connected to the first valve core 503, and the second gear 506 is coaxially and fixedly connected to the second valve core 504. A push rod motor 509 is fixedly mounted on the mounting box 5, and the output shaft of the push rod motor 509 is fixedly connected to the rack 508. Starting the push rod motor 509 moves the rack 508, which in turn rotates the first gear 505 and the second gear 506, causing the first valve core 503 and the second valve core 504 to rotate synchronously. Periodically starting the push rod motor 509 periodically seals the oxygen connection pipe 303 and the negative pressure connection pipe 401, thus enabling periodic oxygen delivery and secretion absorption.
[0034] like Figure 6-9As shown, the inner wall of the adsorption pore 7 is provided with multiple cleaning holes 6, which correspond one-to-one with multiple air holes 201 and are coaxially arranged. A sealing mechanism is installed inside the adsorption pore 7, which seals the cleaning holes 6 during oxygen delivery. The sealing mechanism includes a connecting piece 601 fixedly installed at one end of the multi-chamber tube 1, a second support rod 602 fixedly installed on the connecting piece 601, and a sealing piece 603 fixedly installed on the second support rod 602. The sealing piece 603 is provided with multiple first chamber holes 604 and second chamber holes 605, which correspond one-to-one and are coaxially arranged. The inner diameter of the first chamber hole 604 is smaller than that of the second chamber hole 605. An elastic pad 606 is fixedly installed on the second chamber hole 605, and a conical block 607 is fixedly installed on the elastic pad 606. The elastic pad 606 is provided with multiple delivery holes 608. When oxygen is being delivered, the elastic pad 606 remains extended due to its elasticity. At this time, the cone block 607 is located inside the first cavity 604, effectively sealing it and preventing oxygen from entering the adsorption cavity 7 through the cleaning hole 6. This prevents a reduction in oxygen flow and ensures that all oxygen passes through the vent 201 into the glottis. When the vent 201 is blocked by secretions from the glottis, a medical negative pressure pump applies negative pressure to the negative pressure connecting pipe 401, causing the adsorption cavity 7 to exert suction on the elastic pad 606. Under this suction, the elastic pad 606 moves to the left, which in turn moves the cone block 607 to the left. At this point, the conical block 607 will be unable to block the first cavity 604. The suction force generated by the adsorption hole 7 will act on the cleaning hole 6 through the first cavity 604, thereby cleaning the secretions adhering to the vent 201. This allows the secretions adhering to the vent 201 to be removed, thus cleaning the vent 201 and ensuring the flow of oxygen when the vent 201 is delivered. The secretions at the glottis can be cleaned without repeated insertion and removal, avoiding the discomfort caused to the patient by repeated insertion and removal. When the adsorption hole 7 no longer generates suction, the elastic pad 606 will once again drive the conical block 607 to block the first cavity 604 under its own elastic force.
[0035] Working principle: During use, the end with the air hole 201 is directly inserted into the glottis to ensure sufficient oxygen supply. The oxygen connecting tube 303 is connected to an oxygen concentrator, which delivers oxygen to the oxygen connecting tube 303. The oxygen then enters the oxygen delivery hole 2 through the delivery tube 302 and the split tube 3, and is finally delivered directly to the glottis through the air hole 201. The negative pressure connecting tube 401 is connected to a medical negative pressure pump, which creates suction at the adsorption hole 7, allowing secretions at the glottis to be removed through the adsorption hole 7, thus ensuring the flowability of the air hole 201.
[0036] By periodically activating the push rod motor 509, the oxygen connection tube 303 and the negative pressure connection tube 401 can be periodically blocked, thus enabling periodic oxygen delivery and secretion aspiration. This prevents the adsorption hole 7 from drawing out the oxygen delivered to the glottis, avoiding a reduction in oxygen flow and affecting the oxygen therapy effect.
[0037] When oxygen is delivered, the cone block 607 blocks the first cavity 604, preventing oxygen from entering the adsorption cavity 7 through the cleaning hole 6, thus preventing a reduction in oxygen flow and ensuring that all oxygen enters the glottis through the vent 201. When the vent 201 is blocked by secretions at the glottis, a medical negative pressure pump applies negative pressure to the negative pressure connecting tube 401. When the elastic pad 606 is subjected to suction, it moves to the left, thereby moving the cone block 607 to the left. At this time, the cone block 607 can no longer block the first cavity 604. The suction generated by the adsorption cavity 7 then acts on the cleaning hole 6 through the first cavity 604, thereby cleaning the secretions adhering to the vent 201 through the cleaning hole 6, thus removing the secretions adhering to the vent 201.
[0038] The above specific embodiments are merely several optional embodiments of this utility model.
