Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a medical oxygen humidification and delivery device and a medical oxygen supply system. Background Technology

[0002] In existing medical oxygen supply systems, oxygen is typically delivered directly from the oxygen supply equipment to the patient's respiratory system through pipes. While this method is simple and direct, if the oxygen is not properly humidified, it can cause dryness in the patient's throat and trachea, leading to discomfort, sore throat, or other respiratory problems. Therefore, to ensure a comfortable treatment experience and effective respiratory therapy for patients using oxygen supply equipment, a medical oxygen humidification delivery device is needed to humidify the oxygen delivered by the medical oxygen supply system. This ensures the oxygen has appropriate humidity, preventing respiratory dryness. This not only prevents discomfort caused by respiratory dryness but also optimizes the effectiveness of treatment methods, providing patients with a more comfortable and safer treatment experience.

[0003] A humidification device for medical oxygen delivery, with announcement number CN121490226A, has solved the technical drawback of not being able to quickly adjust oxygen humidity according to individual differences and specific conditions. However, in actual use, similar structures still have many defects. For example, traditional devices lack an automatic linkage mechanism between liquid level changes and the liquid replenishment mechanism. When the liquid level drops, it cannot trigger timely and accurate liquid replenishment, resulting in fluctuations in humidification effect and difficulty in ensuring that the humidifying liquid is continuously in the optimal liquid level range.

[0004] Therefore, the aforementioned technical problems need to be solved. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, this invention proposes a medical oxygen humidification delivery device and a medical oxygen supply system to solve the problem that when the liquid level drops, it is impossible to trigger timely and accurate liquid replenishment, resulting in fluctuations in the humidification effect and difficulty in ensuring that the humidification liquid remains in the optimal liquid level range.

[0006] To solve the above-mentioned technical problems, the basic technical solution proposed by this invention is as follows:

[0007] A medical oxygen humidification delivery device includes a mobile box, an oxygen humidifier, a humidification bottle, and a replenishment mechanism. A folding frame is mounted inside the mobile box via bearings. The oxygen humidifier is clamped and mounted on top of the folding frame. A heating base is embedded in the bottom of the front of the oxygen humidifier, and a linkage mechanism is fixedly installed inside the heating base. The humidification bottle is placed on top of the heating base. A replenishment port is installed on one side of the top of the humidification bottle. A float is movably mounted inside the humidification bottle, and a conduit is fixedly installed at the bottom of the replenishment port, with the bottom end of the conduit penetrating the float. The float plate has a fixedly installed perforated mesh, and a telescopic toothed rod is fixedly installed at the bottom of the perforated mesh. The telescopic toothed rod extends into the heating base and is connected to the linkage mechanism. The liquid replenishment mechanism is fixedly installed inside the oxygen humidifier. The liquid replenishment mechanism consists of a liquid storage tank, an active liquid replenishment component, and a transmission component. One side of the liquid storage tank is connected to the liquid replenishment port through a pipe. The active liquid replenishment component is rotatably installed inside the liquid storage tank. The transmission component is rotatably installed on one side of the liquid storage tank and extends into the heating base and is connected to the linkage mechanism.

[0008] Preferably, the linkage mechanism consists of a mounting shaft frame, a second linkage gear, a cam groove plate, a linkage shaft assembly, and a second transmission gear. The second linkage gear is rotatably mounted inside the mounting shaft frame. One side of the cam groove plate is fixedly connected to one side of the second linkage gear via a shaft. One end of the linkage shaft assembly is movably connected to the sliding groove on the front of the cam groove plate. The back of the second transmission gear is movably mounted on the front of the mounting shaft frame via the mounting shaft.

[0009] The linkage shaft assembly consists of a transmission shaft, a movable groove rod, a sliding groove rod, and a sliding rack. The movable groove rod is movably mounted on the mounting shaft on the back of the second transmission gear via a sliding groove. One end of the transmission shaft and one end of the sliding groove rod are movably connected to the top of one side of the movable groove rod via a shaft bolt. The other end of the transmission shaft is movably connected to the sliding groove on the front of the cam groove plate. A sliding rack is movably mounted on the bottom of the sliding groove rod and meshes with the second transmission gear. One end of the sliding rack is movably connected to the front of the cam groove plate via a shaft bolt. A locking tooth is fixedly mounted on the bottom of one side of the movable groove rod.

[0010] Preferably, the active fluid replenishment assembly consists of a lead screw, a sleeve, and a piston disc. The lead screw is rotatably installed inside the liquid storage tank, the sleeve is embedded inside the piston disc, and the sleeve is sleeved on the outside of the lead screw.

[0011] Preferably, the transmission assembly consists of a first linkage gear and a first transmission gear. One side of the first linkage gear is fixedly connected to one end of the lead screw, the first transmission gear meshes with the first linkage gear, and one side of the first transmission gear is fixedly connected to the mounting shaft on the back of the second transmission gear via a transmission rod.

[0012] Preferably, the heating base consists of a mounting base, a heating plate, and a heating tube, with the heating plate fixedly mounted on the top of the mounting base and the heating tube fixedly mounted on the bottom of the heating plate.

[0013] Preferably, the top of the humidification bottle is provided with an oxygen inlet and an oxygen outlet, and the bottom of the oxygen inlet is provided with a vent pipe that extends through the perforated mesh to the bottom of the humidification bottle.

[0014] Preferably, an oxygen supply pipe is fixedly installed on the front of the oxygen humidifier, the bottom of one end of the oxygen supply pipe is connected to the oxygen inlet, a breathing tube is threadedly installed on the top of one end of the oxygen supply pipe, the bottom of the breathing tube passes through one end of the oxygen supply pipe and is connected to the oxygen outlet, and an air-oxygen mixer is fixedly installed on one side inside the oxygen humidifier.

[0015] Preferably, the folding frame consists of a tray, two sets of folding shafts, a clamping mechanism, and a locking mechanism. The two sets of folding shafts are respectively installed on both sides of the tray by bolts. The clamping mechanism is installed on the bottom of the tray by bearings and extends to the top of the tray by a slide groove. The locking mechanism is installed on the inside of the tray by bolts.

[0016] Preferably, an oxygen generator is placed inside the mobile box, and a connecting seat is fixedly installed on the top of the oxygen generator, extending to the top of the mobile box.

[0017] A medical oxygen supply system with a medical oxygen humidification delivery device involves pushing a mobile box to the patient's bedside, connecting it to a power source via a power cord, attaching a breathing tube to the patient's nose, and turning on the oxygen generator, oxygen humidifier, and heating base.

[0018] The humidifying liquid stored inside the humidification bottle is heated by a heating base, and then oxygen is generated by the oxygen generator. The oxygen is delivered to the air-oxygen mixer through the connector, and the air-oxygen mixer mixes the oxygen with air and delivers it to the oxygen delivery tube. The oxygen delivery tube delivers the mixed oxygen through the oxygen inlet to the ventilation tube, and the ventilation tube delivers the mixed oxygen to the heated humidifying liquid inside the humidification bottle. The humidified mixed oxygen is delivered to the oxygen outlet through the distribution mesh, and the oxygen outlet delivers the heated and humidified mixed oxygen to the patient's nasal passage through the breathing tube.

[0019] When the level of the humidifying liquid inside the humidification bottle drops, the float plate drives the telescopic rack to move down synchronously through the distributed perforated mesh. The moving telescopic rack drives the linkage mechanism to move. The running linkage mechanism drives the active replenishment component to operate through the transmission component, transporting the humidifying liquid inside the storage tank to the replenishment port through the pipeline. The replenishment port then transports the humidifying liquid unidirectionally into the humidification bottle, actively replenishing the humidifying liquid inside the humidification bottle and keeping the humidifying liquid inside the humidification bottle stable.

[0020] The beneficial effects of this invention are:

[0021] The technical solution of this invention achieves automatic liquid replenishment based on liquid level changes by incorporating a telescopic gear, a liquid replenishment mechanism, and a linkage mechanism. The telescopic gear moves up and down with the liquid level changes inside the humidification bottle, thus descending as the liquid level decreases. Specifically, the float accurately follows the changes in the humidification liquid inside the bottle. The movement of the float drives the telescopic gear downwards synchronously through a perforated mesh. The descending telescopic gear drives the transmission component in the liquid replenishment mechanism via the linkage mechanism. The transmission component further drives the liquid replenishment component, transporting the humidification liquid from the storage tank to the replenishment port through a pipeline. This unidirectional transport from the replenishment port to the humidification bottle ensures the device maintains dynamic balance during liquid consumption, keeping the humidification liquid level within the bottle consistently within the optimal range, thus maintaining a stable humidification effect. This achieves automatic and timely replenishment of the humidification liquid, solving the problem of insufficient humidification caused by liquid level fluctuations, thereby improving the stability and reliability of humidification.

[0039] The following will be combined with the appendix Figure 1 To be continued Figure 15 The technical solutions in the embodiments of the present invention have been clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0040] A medical oxygen humidification delivery device includes a mobile box 1, an oxygen humidifier 3, a humidification bottle 4, and a replenishment mechanism 6. A folding frame 2 is mounted inside the mobile box 1 via bearings. The oxygen humidifier 3 is clamped and mounted on the top of the folding frame 2. A control panel is embedded in the top of the oxygen humidifier 3. The control panel is electrically connected to an air-oxygen mixer 303 and a heating base 5 via wires, facilitating control of the operation of the air-oxygen mixer 303 and the heating base 5. A heating base 5 is embedded in the bottom front of the oxygen humidifier 3. When powered on, the heating base 5 generates heat to constantly heat the humidification liquid inside the humidification bottle 4, raising and maintaining the temperature of the humidification liquid. The humidified oxygen can more effectively moisten the inhaled air, thereby reducing respiratory discomfort and improving the comfort of the breathing process.

[0041] The heating base 5 is internally fixedly equipped with a linkage mechanism 7; wherein, the linkage mechanism 7 is composed of a mounting shaft frame 701, a second linkage gear 702, a cam groove plate 703, a linkage shaft assembly 704, and a second transmission gear 705. The second linkage gear 702 is rotatably mounted inside the mounting shaft frame 701. One side of the cam groove plate 703 is fixedly connected to one side of the second linkage gear 702 through a shaft. One end of the linkage shaft assembly 704 is movably connected to the sliding groove on the front side of the cam groove plate 703. The back side of the second transmission gear 705 is movably mounted on the front side of the mounting shaft frame 701 through the mounting shaft.

[0042] The linkage shaft assembly 704 consists of a transmission shaft 7041, a movable groove rod 7042, a sliding groove rod 7043, and a sliding rack 7044. The movable groove rod 7042 is movably mounted on the mounting shaft on the back of the second transmission gear 705 via a sliding groove. One end of the transmission shaft 7041 and one end of the sliding groove rod 7043 are movably connected to the top of one side of the movable groove rod 7042 via a shaft bolt. The other end of the transmission shaft 7041 is movably connected to the sliding groove on the front of the cam groove plate 703. The sliding rack 7044 is movably mounted on the bottom of the sliding groove rod 7043. The sliding rack 7044 meshes with the second transmission gear 705. One end of the sliding rack 7044 is movably connected to the front of the cam groove plate 703 via a shaft bolt. A locking tooth 7045 is fixedly mounted on the bottom of one side of the movable groove rod 7042.

[0043] In this configuration, the cam groove disk 703 is eccentrically connected to one end of the slide bar rack 7044, and the transmission shaft 7041 is mounted on the front of the mounting bracket 701 via a shaft.

[0044] The telescopic rack 4051 drives the meshing second linkage gear 702 to rotate in both directions. The rotating second linkage gear 702 drives the cam groove disk 703 to rotate through the shaft. The rotating cam groove disk 703 drives the mounting shaft bracket 701 to rotate through the slide groove, and also drives the slide rack 7044 to telescopically move within the slide groove rod 7043. One end of the rotating mounting shaft bracket 701 pulls the moving groove rod 7042 up and down through the shaft bolt. The moving groove rod 7042 drives the slide rack 7044 up and down through the slide groove rod 7043, so that the slide rack 7044 dynamically meshes with the second transmission gear 705. When the slide rack 7044 meshes with the second transmission gear 705, the telescopically moving slide groove rod 7043 drives the meshing second transmission gear 705 to rotate intermittently.

[0045] Humidification bottle 4 is placed on top of heating base 5. A liquid inlet 403 is installed on one side of the top of humidification bottle 4. A float plate 404 is movably installed inside humidification bottle 4. A conduit is fixedly installed at the bottom of liquid inlet 403. The bottom end of the conduit passes through float plate 404. A distribution mesh 405 is fixedly installed inside float plate 404. A telescopic toothed rod 4051 is fixedly installed at the bottom of distribution mesh 405. The telescopic toothed rod 4051 extends into the interior of heating base 5 and is connected to the linkage mechanism 7.

[0046] The telescopic rack 4051 is meshed with the second linkage gear 702. The distribution mesh 405 uniformly refines the humidified mixed oxygen before delivering it to the oxygen outlet 402. The float 404 moves telescopically and expands with the liquid level by driving the telescopic rack 4051 through the distribution mesh 405.

[0047] The replenishment mechanism 6 is fixedly installed inside the oxygen humidifier 3. The replenishment mechanism 6 consists of a liquid storage tank 601, an active replenishment component, and a transmission component. One side of the liquid storage tank 601 is connected to the replenishment port 403 through a pipe. The active replenishment component is rotatably installed inside the liquid storage tank 601. The transmission component is rotatably installed on one side of the liquid storage tank 601 and extends into the heating base 5 and is connected to the linkage mechanism 7.

[0048] The active fluid replenishment assembly consists of a lead screw 603, a sleeve 604, and a piston disc 605. The lead screw 603 is rotatably installed inside the liquid storage tank 601, and the sleeve 604 is embedded inside the piston disc 605, with the sleeve 604 sleeved on the outside of the lead screw 603.

[0049] The transmission assembly consists of a first linkage gear 602 and a first transmission gear 606. One side of the first linkage gear 602 is fixedly connected to one end of the lead screw 603. The first transmission gear 606 meshes with the first linkage gear 602. One side of the first transmission gear 606 is fixedly connected to the mounting shaft on the back of the second transmission gear 705 through a transmission rod 607.

[0050] The second transmission gear 705 drives the active liquid replenishment component to operate through the transmission assembly. Specifically, the rotational power is transmitted to the first transmission gear 606 through the transmission rod 607. The rotating first transmission gear 606 drives the lead screw 603 to rotate through the meshing first linkage gear 602. The lead sleeve 604 converts the rotational power of the lead screw 603 into linear movement, which drives the piston disc 605 to move, squeezing the humidifying liquid stored inside the liquid storage tank 601 and outputting it into the liquid storage tank 601 through the pipeline.

[0051] like Figures 11 to 12 As shown, the heating base 5 consists of a mounting base 501, a heating plate 502, and a heating tube 503. The heating plate 502 is fixedly installed on the top of the mounting base 501, and the heating tube 503 is fixedly installed on the bottom of the heating plate 502.

[0052] The mounting base 501 and the heating plate 502 form a sealed whole to prevent heat loss from the heating tube 503. The mounting base 501 is equipped with a temperature sensor to detect the heating temperature of the heating tube 503 in real time. When the heating tube 503 is powered on, it converts electrical energy into heat energy and transfers it to the heating plate 502. The heating plate 502 ensures the uniformity of the heating process and avoids local overheating or uneven heating, thereby improving heating efficiency and safety. Since the heating plate 502 is in contact with the bottom of the humidification bottle 4, it transfers heat to the humidification bottle 4 to heat the humidifying liquid inside the humidification bottle 4.

[0053] like Figures 8 to 12 As shown, the top of the humidification bottle 4 is provided with an oxygen inlet 401 and an oxygen outlet 402. The bottom of the oxygen inlet 401 is provided with a ventilation pipe 4011. The ventilation pipe 4011 extends through the distribution mesh 405 to the bottom of the humidification bottle 4. An oxygen supply pipe 301 is fixedly installed on the front of the oxygen humidifier 3. The bottom of one end of the oxygen supply pipe 301 is connected to the oxygen inlet 401. A breathing pipe 302 is threaded onto the top of one end of the oxygen supply pipe 301. The bottom of the breathing pipe 302 passes through one end of the oxygen supply pipe 301 and is connected to the oxygen outlet 402. An air-oxygen mixer 303 is fixedly installed on one side inside the oxygen humidifier 3.

[0054] The output end of the air-oxygen mixer 303 is connected to the oxygen delivery pipe 301 via a pipe. The back of the air-oxygen mixer 303 is connected to the connector 101 via an oxygen pipe, so that the oxygen generated by the oxygen generator 102 is delivered to the air-oxygen mixer 303 through the pipe connected to the connector 101. The air-oxygen mixer 303 mixes oxygen and air in a set ratio, and the mixture is then delivered to the oxygen delivery pipe 301 through a pipe. The oxygen delivery pipe 301 delivers the oxygen through the oxygen inlet 401 to the ventilation pipe 4011, and through the ventilation pipe 4011 to the bottom of the humidification bottle 4. When the oxygen passes through the ventilation pipe 4011, it can fully contact the liquid inside the humidification bottle 4, increasing the humidity of the oxygen. This ensures that the oxygen has been fully humidified before entering the patient's respiratory tract through the breathing tube 302, reducing irritation to the respiratory tract and improving the patient's comfort and treatment effect.

[0055] like Figures 4 to 7 As shown, the folding frame 2 consists of a tray 201, two sets of folding shafts 202, a clamping mechanism 203, and a locking mechanism 204. The two sets of folding shafts 202 are respectively installed on both sides of the tray 201 by shaft bolts. The clamping mechanism 203 is installed on the bottom of the tray 201 by bearings, and the clamping mechanism 203 extends to the top of the tray 201 by a slide groove. The locking mechanism 204 is installed on the inside of the tray 201 by shaft bolts.

[0056] The tray 201 provides a placement position for the oxygen humidifier 3; and the clamping mechanism 203 clamps and locks the oxygen humidifier 3, so that the oxygen humidifier 3 remains stable and safe when the folding frame 2 is flipped and folded.

[0057] Two sets of folding shafts 202 are respectively installed on both sides of the tray 201 by shaft bolts, forming a hinge structure, allowing the tray 201 to fold around these shafts; a locking rod is fixedly installed on the inner side of one set of folding shafts 202, and the locking rod cooperates with the locking mechanism 204 to lock the position of the set of folding shafts 202, thereby locking the position of the tray 201; when the oxygen humidifier 3 needs to be used, the tray 201 is manually pulled to rotate the two sets of folding shafts 202. When rotated to a horizontal position, the locking mechanism 204 locks the locking rods inside one set of folding shafts 202, ensuring the stability of the tray 201 and allowing the oxygen humidifier 3 on the tray 201 to be displayed for easy use. When the oxygen humidifier 3 needs to be stored, the locking mechanism 204 is manually pulled to release the locking rods inside one set of folding shafts 202, allowing the tray 201 to rotate and fold down with the two sets of folding shafts 202 and move into the mobile box 1 for storage and protection of the oxygen humidifier 3.

[0058] like Figures 1 to 4As shown, an oxygen generator 102 is placed inside the mobile box 1, and a connecting seat 101 is fixedly installed on the top of the oxygen generator 102, extending to the top of the mobile box 1.

[0059] The oxygen generator 102 includes a compressor, a molecular sieve tower, an oxygen storage tank, a filtration system, and an intelligent control system. It adopts pressure swing adsorption technology, which utilizes the high adsorption capacity of zeolite molecular sieves for nitrogen. After air is filtered by the filtration system, it is delivered to the compressor. After being compressed, cooled, and filtered by the compressor, it enters the molecular sieve tower. Under high pressure, nitrogen is adsorbed by the molecular sieve, and oxygen is collected through it. After the molecular sieve is saturated, nitrogen is released by depressurization or vacuuming to complete regeneration. The two towers work alternately to achieve continuous oxygen supply. The oxygen is delivered to the oxygen storage tank through pipelines for storage. The oxygen storage tank is connected to the connecting seat 101 through pipelines. The connecting seat 101 delivers the oxygen stored in the oxygen storage tank to the air-oxygen mixer 303 through pipelines.

[0060] A medical oxygen supply system for a medical oxygen humidification delivery device involves pushing a mobile box 1 to the patient's bedside, connecting it to a power source via a power cord, putting a breathing tube 302 on the patient's nose, and turning on the oxygen generator 102, oxygen humidifier 3, and heating base 5.

[0061] The humidifying liquid stored inside the humidification bottle 4 is heated by the heating seat 5, and then oxygen is generated by the oxygen generator 102. The oxygen is delivered to the air-oxygen mixer 303 through the connecting seat 101. The air-oxygen mixer 303 mixes the oxygen with air and delivers it to the oxygen delivery tube 301. The oxygen delivery tube 301 delivers the mixed oxygen through the oxygen inlet 401 to the ventilation tube 4011. The ventilation tube 4011 delivers the mixed oxygen to the heated humidifying liquid inside the humidification bottle 4. The humidified mixed oxygen is delivered to the oxygen outlet 402 through the distribution mesh 405. The oxygen outlet 402 delivers the heated and humidified mixed oxygen to the patient's nose through the breathing tube 302, so that the patient can inhale a mixed gas containing an appropriate ratio of oxygen and air.

[0062] When the liquid level of the humidifying liquid inside the humidifying bottle 4 drops, the float plate 404 drives the telescopic rack 4051 to move down synchronously through the distribution mesh 405. The moving telescopic rack 4051 drives the linkage mechanism 7 to move. Specifically, the moving telescopic rack 4051 drives the meshing second linkage gear 702 to rotate. The rotating second linkage gear 702 drives the cam groove disk 703 to rotate through the shaft. The rotating cam groove disk 703 drives the mounting bracket 701 to rotate through the slide groove, and drives the slide rack 7044 to move telescopically within the slide rod 7043.

[0063] One end of the rotating mounting bracket 701 pulls the movable groove rod 7042 downward via a shaft bolt. The downward-moving movable groove rod 7042 drives the sliding rack 7044 downward via the sliding groove rod 7043, causing the sliding rack 7044 to dynamically mesh with the second transmission gear 705. At this time, the movable sliding groove rod 7043 drives the meshed second transmission gear 705 to rotate. The rotating second transmission gear 705 transmits the rotational power to the first transmission gear 606 via the transmission rod 607. The gear 606 drives the lead screw 603 to rotate through the meshing first linkage gear 602. The lead sleeve 604 converts the rotational power of the lead screw 603 into linear movement, which drives the piston disc 605 to move and squeeze the humidifying liquid stored inside the storage tank 601. The squeezed humidifying liquid is transported through the pipeline to the replenishment port 403, and then transported unidirectionally to the humidification bottle 4 through the replenishment port 403, ensuring that the humidifying liquid inside the humidification bottle 4 is continuously at the required level, thus achieving the effect of automatically replenishing the humidifying liquid inside the humidification bottle 4.

Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and alterations to the present invention should also fall within the protection scope of the claims of the present invention. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the present invention.
