Description

Technical Field

[0001] This application belongs to the field of ventilator humidification, specifically relating to an external ventilator humidification structure. Background Technology

[0002] With the advancement of modern medicine, sleep medicine has gradually been established and developed as an important component of modern medicine. Research on sleep breathing is directly related to the study of sleep disorders, thus sleep breathing has become a major concern in sleep medicine. Sleep apnea-hypopnea syndrome is relatively common in adults, and its clinical characteristics include recurrent episodes of severe snoring and apnea. Besides causing or worsening respiratory failure, it is also a significant risk factor for cerebrovascular accidents, myocardial infarction, and hypertension. In addition to drug treatment, modern medical technology widely uses medical devices such as sleep apnea machines to treat or improve sleep conditions. When using a sleep apnea machine, because the instrument ventilates the patient's body for extended periods, it is necessary to maintain the relative humidity of the air entering the patient's body at 50%–85%. How to solve the problem of humidifying the gas in the ventilator without making the machine too large and affecting portability has become a technical challenge in the industry. The most common humidification solution currently available is a ventilator with a built-in water tank, i.e., a ventilator with integrated humidification and heating. The water in the built-in humidification tank is heated and vaporized to enter the breathing tubing. The internal water tank increases the size of the ventilator, making it inconvenient to carry around and use. There are other humidification solutions on the market, such as humidifying by recycling the water vapor exhaled by the patient, i.e., waterless humidification. Although it can be compact and convenient, the humidification effect is not ideal and cannot meet the requirements for high relative humidity. Utility Model Content

[0003] In view of the problems existing in the prior art, this utility model provides an external humidification structure for a ventilator. This humidification structure does not include a water tank, which greatly reduces the size of the sleep apnea machine, making the overall size of the sleep apnea machine small and easy to carry.

[0004] The technical solution adopted in this utility model is as follows:

[0005] An external humidification structure for a ventilator is T-shaped and includes an air tube that is connected at one end to the air outlet of a sleep apnea machine and at the other end to a breathing tubing. A water-absorbing part is provided below the air tube. The water-absorbing part includes a mounting base connected to the air tube, a straight tube connected below the mounting base, and an absorbent cotton swab disposed inside the straight tube with its top end extending into the air tube. A heating element is provided at the top of the absorbent cotton swab, and the heating element is electrically connected to the sleep apnea machine.

[0006] Furthermore, the two ends of the air tube narrow to form ports for connection with the sleep apnea machine and the breathing circuit, respectively, while the middle expands to form a cavity to contain water vapor. The air tube has an opening for connection with the mounting base, and the shape of the opening is consistent with the shape of the top of the mounting base, so as to achieve a sealed connection between the air tube and the mounting base. The air tube can be, for example, a plastic tube, and the size of the air tube port is a standard size in the industry, which is compatible with most sleep apnea machines on the market.

[0007] Furthermore, the mounting base includes a top plate for sealing the opening of the air duct, a threaded tube connected below the top plate, and an insertion tube disposed inside the threaded tube and extending upward through the top plate into the cavity of the air duct. The edge of the top plate is bent upward to form a disc shape. The top plate can be, for example, circular. The threaded tube is an internally threaded tube. The thread of the threaded tube is preferably adapted to the thread of the mouth of a mineral water bottle on the market. The top edge of the insertion tube expands radially outward to form a step for fixing the heating element.

[0008] Furthermore, the bottom end of the straight tube is closed, the straight tube and the insert tube are coaxial, and the top end of the straight tube is connected to the bottom end of the insert tube. The straight tube and the insert tube are detachably connected or integrally connected, preferably detachably connected, such as by a threaded connection. Detachable connection facilitates replacement of absorbent cotton swabs. The straight tube has through holes for water to enter its interior. The through holes can be, for example, elongated. The length direction of the through holes is preferably consistent with the axial direction of the straight tube. Water enters the straight tube through the through holes, is absorbed by the absorbent cotton swabs, and continuously seeps towards the top of the absorbent cotton swabs until the entire absorbent cotton swab is full of water. While absorbing water, the absorbent cotton swabs filter impurities in the water.

[0009] Furthermore, a limiting post protruding towards the absorbent cotton swab is provided at the bottom of the straight tube. A spring is sleeved on the limiting post, with the top of the spring connected to the absorbent cotton swab and the bottom of the spring abutting against the bottom of the straight tube. The spring is in a compressed state and applies an upward pushing force to the absorbent cotton swab, causing the top of the absorbent cotton swab to be in close contact with the heating plate. When the heating plate is energized, it generates heat, and the moisture at the point where the absorbent cotton swab is in contact with the heating plate is heated and generates water vapor. The water vapor enters the airway and then the breathing circuit, thereby achieving the effect of humidifying the patient's inhalation. As the moisture at the top of the absorbent cotton swab is consumed, the moisture at the distal end of the absorbent cotton swab is continuously replenished towards the heating plate.

[0010] Furthermore, the heating element is electrically connected to the sleep apnea machine via a PCB board, and the PCB board realizes the circuit control of the heating element. The heating element is equipped with an electric heating wire.

[0011] Furthermore, the PCB board is fixed to the top plate of the mounting base, and a waterproof and moisture-proof layer is coated on the PCB board.

[0012] Furthermore, an electrical socket is provided at the connection between the air tube and the mounting base. The electrical socket is electrically connected to the PCB board. When power needs to be supplied to the heating element, the wire is inserted into the electrical socket, and the other end of the wire is connected to the sleep apnea machine. The power of the heating element is adjusted by the sleep apnea machine to control the degree of gas humidification.

[0013] Furthermore, the mounting base is equipped with anti-slip ribs to facilitate the connection between the mounting base and the water container.

[0014] The beneficial effects of this utility model are:

[0015] This invention relates to an external humidification structure for a ventilator. A straight tube is inserted into a water storage container, and an absorbent cotton swab absorbs the water. A heating element, when energized, generates heat, heating the water and producing steam. The steam enters the air delivery tube and then the breathing circuit, thus humidifying the patient's inhalation. No dedicated water tank is required; any water storage container can achieve gas humidification. The absorbent cotton swab acts as a filter, removing impurities from the water. When humidification is needed, the air delivery tube is inserted into the air outlet of the sleep apnea machine, and the straight tube is inserted into the water storage container. It is then powered on and ready to use. When not in use, it is unplugged from the sleep apnea machine and stored away. This external humidification structure eliminates the traditional water tank humidifier of sleep apnea machines, adopting a tankless humidifier solution, making the sleep apnea machine smaller and more portable.

[0029] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] like Figure 1-8As shown, an external humidification structure for a ventilator is T-shaped and includes an air duct 1 connected at one end to the air outlet of a sleep apnea machine and at the other end to a breathing tubing. A water-absorbing part is provided below the air duct 1. The water-absorbing part includes a mounting base 2 connected to the air duct 1, a straight tube 3 connected below the mounting base 2, and an absorbent cotton swab 4 disposed inside the straight tube 3 with its top end extending into the air duct 1. A heating element 7 is provided at the top of the absorbent cotton swab 4, and the heating element 7 is electrically connected to the sleep apnea machine.

[0031] The two ends of the air tube 1 narrow to form ports for connection with the sleep apnea machine and the breathing tubing, respectively, while the middle expands to form a cavity to contain water vapor. The air tube 1 has an opening for connection with the mounting base 2, and the shape of the opening is consistent with the shape of the top of the mounting base 2 to achieve a sealed connection between the air tube 1 and the mounting base 2. The air tube 1 can be, for example, a plastic tube. The size of the port of the air tube 1 is a standard size in the industry and is compatible with most sleep apnea machines on the market.

[0032] Mounting base 2 includes a top plate 201 for sealing the opening of the air duct 1, a threaded tube 202 connected below the top plate 201, and an insertion tube 203 disposed in the threaded tube 202 and extending upward through the top plate 201 into the cavity of the air duct 1. The edge of the top plate 201 is bent upward to form a disc shape. The top plate 201 can be circular, for example. The threaded tube 202 is an internally threaded tube. The thread of the threaded tube 202 is preferably adapted to the thread of the mouth of a mineral water bottle on the market. The top edge of the insertion tube 203 expands outward in a radial direction to form a step for fixing the heating element 7.

[0033] The bottom end of the straight tube 3 is closed. The straight tube 3 is coaxial with the insertion tube 203. The top end of the straight tube 3 is connected to the bottom end of the insertion tube 203. The straight tube 3 and the insertion tube 203 can be detachably connected or integrally connected. It is preferred to be detachably connected, such as by a threaded connection. The detachable connection makes it easy to replace the absorbent cotton swab 4. The straight tube 3 has through holes 301 distributed on it to allow water to enter its interior. The through holes 301 can be elongated, for example. The length direction of the through holes 301 is preferably consistent with the axial direction of the straight tube 3. Water enters the straight tube 3 through the through holes 301. The water is absorbed by the absorbent cotton swab 4 and continuously seeps to the top of the absorbent cotton swab 4 until the entire absorbent cotton swab 4 is full of water. While absorbing water, the absorbent cotton swab 4 filters impurities in the water.

[0034] The bottom of the straight tube 3 is provided with a limiting post 5 that protrudes towards the absorbent cotton swab 4. A spring 6 is sleeved on the limiting post 5. The top of the spring 6 is connected to the absorbent cotton swab 4, and the bottom of the spring 6 abuts against the bottom of the straight tube 3. The spring 6 is in a compressed state and applies an upward pushing force to the absorbent cotton swab 4, so that the top of the absorbent cotton swab 4 is in close contact with the heating plate 7. When the heating plate 7 is energized, it generates heat. The water in the absorbent cotton swab 4 that is in close contact with the heating plate 7 is heated and generates water vapor. The water vapor enters the airway tube 1 and then enters the breathing circuit, thereby achieving the effect of humidifying the patient's inhalation. As the water at the top of the absorbent cotton swab 4 is consumed, the water at the distal end of the absorbent cotton swab 4 is continuously replenished towards the heating plate 7.

[0035] The heating element 7 is electrically connected to the sleep apnea machine via the PCB board 8. The PCB board 8 realizes the circuit control of the heating element 7, and the heating element 7 is equipped with an electric heating wire.

[0036] The PCB board 8 is fixed on the top plate 201 of the mounting base 2, and a waterproof and moisture-proof layer is coated on the PCB board 8.

[0037] The connection between the air duct 1 and the mounting base 2 is provided with an electrical socket 9. The electrical socket 9 is electrically connected to the PCB board 8. When it is necessary to power the heating element 7, the wire is inserted into the electrical socket 9, and the other end of the wire is connected to the sleep apnea machine. The power of the heating element 7 is adjusted by the sleep apnea machine to control the degree of gas humidification. The electrical socket 9 can be, for example, a USB port.

[0038] The mounting base 2 is provided with anti-slip ribs 10 to facilitate the connection between the mounting base 2 and the water storage container.

[0039] In use, the external humidification structure of this utility model allows the straight tube 3 to be inserted into a water storage container, such as a mineral water bottle. It can be threaded into the water storage container or placed directly in the water of the water storage container. When the port of the air delivery tube 1 is connected to the air outlet of the sleep apnea machine, the humidification structure of this utility model is suspended in the air. The water storage container, such as a basin or bowl, moves from bottom to top until the water in the water storage container enters the straight tube 3 and is absorbed by the absorbent cotton swab 4. A support can be placed under the water storage container and the water storage container can be placed on the support to free up the hands.

[0040] The preferred embodiments of this utility model have been described above; however, the above description is not intended to be limiting. Those skilled in the art can make many changes or modifications to this utility model without departing from its spirit and scope. Such changes or modifications should be included within the scope of the appended claims.
