Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically, it relates to a ventilation therapy device. Background Technology

[0002] Currently, the humidifier tank accounts for a large proportion of the overall size of ventilation therapy equipment on the market, making it inconvenient to carry and store. Therefore, there are many mini sleep apnea machines on the market. If the humidifier tank structure is retained, it is impossible to guarantee that the small size design of the product will not be inconvenient to carry. Subsequently, waterless tank humidification technology was developed, but the humidification capacity of this technology cannot match that of conventional ventilators.

[0003] To address this issue, a waterless humidification (HME) solution was designed and developed. The HME is a small heat and moisture exchanger that retains the heat and humidity of the patient's exhaled air to heat and humidify the inhaled air in the breathing circuit. However, this solution's humidification effect is not ideal, failing to achieve the capabilities of traditional humidification methods, and it also increases airway obstruction and tubing noise. Summary of the Invention

[0004] The purpose of this invention is to overcome the defects of the prior art and to propose a ventilation therapy device. This invention is a ventilation therapy device that can achieve both a small-size product design and the retention of a humidification tank.

[0007] When the ventilation therapy equipment is in the deployed state, the concave rib 5 of the humidification tank 3 and the bottom plate form a liquid storage chamber for storing liquid to humidify the gas.

The gap is used to allow the gas from the fan to enter the main unit ventilation duct chamber 7 through the air inlet, and then be transmitted to the user end through the air outlet.

[0012] Preferably, a partition guide groove 8 is vertically provided on the main unit baffle 9 inside the main unit air passage chamber 7, and the main partition guide groove 8 is provided with an opening. The partition guide groove 8 is used in conjunction with the air passage partition 12 of the humidification tank 3.

At the same time, the opening of the airway partition 12 coincides with the opening on the guide groove 8 of the main unit partition to form an airway passage.

[0014] When the ventilation therapy equipment is in the deployed state, the airway baffle 12 descends, closing the opening on the main unit baffle guide groove 8, and opening the air inlet 10 and air outlet 11 of the humidification tank for humidifying the gas.

[0033] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0034] This invention provides a ventilation therapy device, such as Figure 1-3As shown, the device includes a main unit 1 and a humidification tank 3. Two sealing gaskets 20 are provided between the main unit 1 and the humidification tank 3 to ensure that the air passage remains sealed from the outside when folded and unfolded. The humidification tank 3 includes a base plate 4, concave ribs 5, and airflow guide ribs. The airflow guide ribs are provided inside the humidification tank 3 to increase the combination time between the airflow and water. The humidification tank drain outlet 15 is also provided on the bottom plate 4 of the humidification tank. The main unit 1 includes a fan chamber 6 and a main unit air passage chamber 7. The fan chamber 6 is used to house the fan 16. A water inlet 17 is provided on the housing of the main unit 1, and a water supply pipe 19 is connected inside. Liquid is input into the humidification tank 3 through the water supply pipe 19. A water supply pipe sealing plug 18 is provided on the water inlet 17. A vertically arranged air duct baffle 12 is provided on the bottom plate 4 of the humidification tank to control the gas flow direction. The air duct baffle 12 has an opening in the middle. A humidification tank outlet baffle 14 and a humidification tank inlet baffle 13 are respectively arranged on both sides of the air duct baffle 12 on the bottom plate 4 of the humidification tank. A main unit baffle 9 is arranged between the fan chamber 6 and the main unit ventilation chamber 7. The main unit baffle 9 partially separates the fan chamber 6 and the main unit ventilation chamber 7. The gap is used to allow the gas from the fan 16 to enter the main unit ventilation chamber 7 through the air inlet, and then be transmitted to the user end through the air outlet. A baffle guide groove 8 is vertically arranged on the main unit baffle 9 in the main unit ventilation chamber 7. The main baffle guide groove 8 has an opening in the middle. The baffle guide groove 8 works in conjunction with the air duct baffle 12 of the humidification tank 3.

[0035] The convex rib 2 of the main unit 1 and the concave rib 5 of the humidification tank 3 cooperate with each other to switch the folding and unfolding of the ventilation therapy device. The convex rib 2 of the main unit 1 and the concave rib 5 of the humidification tank 3 are connected by means of snap-fit ​​connection, self-locking mechanism connection or threaded connection to restrict the retraction of the humidification tank.

[0036] The ventilation therapy device of this invention includes two usage states: a folded state and an unfolded state, as detailed below:

[0037] When the ventilation therapy equipment is in a folded state, such as Figure 7-8 As shown, the rib 2 of the main unit 1 and the bottom plate 4 of the humidification tank 3 form an air outlet chamber, which is used to transmit gas through the air inlet into the air outlet chamber and then through the air outlet to the user end; the air inlet baffle 13 and the air outlet baffle 14 of the humidification tank will close the air inlet 10 and the air outlet 11 of the humidification tank in the air passage chamber 7 of the main unit. At the same time, the opening on the air passage baffle 12 coincides with the opening on the guide groove 8 of the main unit baffle, which is used to form an air passage.

[0038] When the ventilation therapy equipment is in the deployed state, such as Figure 4-6As shown, the concave rib 5 of the humidification tank 3 and the bottom plate 4 form a liquid storage chamber for storing liquid to humidify the gas. The air passage baffle 12 descends, closes the opening on the main unit baffle guide groove 8, and opens the air inlet 10 and the air outlet 11 of the humidification tank for humidifying the gas. It can store liquid to meet humidification requirements.

[0039] The humidification tank of this invention is part of the overall housing. When the user needs to use the humidification function of the ventilation therapy device, they only need to pull the humidification tank away from the main unit, thus creating a liquid storage space. Water can be injected into this space through the water pipe to humidify the gas. When the gas from the fan passes through the outlet chamber above the liquid storage space, it carries away the water vapor evaporated from the liquid storage space, thereby achieving the effect of humidifying the gas. When humidification is not needed or when the device is to be stored, the tank can be pushed back towards the main unit.

[0040] When the humidifier is opened, the gas path is as follows: Figure 4-6 As shown:

[0041] When the humidifier canister is opened, the air passage baffle descends accordingly, sealing off the original air passage. The airflow enters the humidifier canister as indicated by the arrow in the diagram. The humidifier canister is equipped with airflow guide ribs to increase the combination time between the airflow and water, thereby improving the humidification capacity. When the humidifier canister is opened, the connection between the main unit and the humidifier can be restricted by a snap-fit ​​mechanism or a self-locking mechanism, but is not limited to this type of connection. The main unit casing is equipped with a water inlet, which is connected to a water supply pipe, allowing users to add water through the water supply pipe.

[0042] When the humidifier is closed, the gas path is as follows: Figure 7-8 As shown:

[0043] When the humidifier canister is folded and closed, the air inlet and outlet baffles at the bottom of the humidifier canister will seal the air inlet and outlet passages from the main unit into the humidifier canister. At the same time, the opening on the air passage baffle coincides with the opening on the guide groove of the main unit baffle, forming an air passage. Two sealing gaskets are installed between the main unit and the humidifier canister to ensure the sealing of the whole machine when it is closed and opened. A drain outlet is provided at the bottom of the humidifier canister to release any remaining water in the canister.

[0044] Furthermore, this invention has no air passage when the humidification tank is closed; the passage is only formed when the humidification tank is open, allowing the user to choose whether or not to humidify the gas by adding water. Additionally, the humidification tank is designed to be easily removable, and its connection to the main unit can be achieved using O-ring seals or threaded installation, facilitating water filling and cleaning.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
