Description

Technical Field

[0001] The utility model relates to a ventilation therapy device, in particular to a snoring sound collection auxiliary unit for the ventilation therapy device. On this basis, the utility model also relates to a ventilation therapy device comprising the snoring sound collection auxiliary unit. Background Art

[0002] In modern clinical medicine, a ventilator is an auxiliary respiratory therapy device with artificial ventilation function. It can supply breathing gas to patients through the breathing tube and the patient interface, thereby increasing the patient's lung ventilation and effectively improving the patient's respiratory function. Ventilators are now widely used to treat respiratory diseases such as respiratory failure, respiratory insufficiency, sleep apnea syndrome, chronic obstructive pulmonary disease, etc., and can play an important role in assisting patients' breathing, saving and prolonging their lives.

[0003] For example, a ventilation therapy device such as a ventilator is usually equipped with a humidifier tank, which is used to heat and humidify the airflow passing through the humidifier tank and then deliver it to the patient, so that the patient can get a good breathing experience. In order to monitor and collect the patient's usage status and related data in real time, it is necessary to set a collection point on the device host, and the snoring collection point is one of them.

[0004] The closer the snoring sound collection point is to the patient's end of use, the more timely and authentic the feedback will be. Therefore, the snoring sound collection point is usually set somewhere between the humidifier tank and the main unit outlet. However, this setting has the following risks: on the one hand, since the airflow will carry the moisture in the humidifier tank to the snoring sound collection point, if the opening of the collection point is not properly handled, the condensed liquid will enter the collection point, causing the collection channel to be blocked, resulting in the failure of the collection function; on the other hand, the breathing tube connected to the main unit outlet for delivering heated airflow to the user end will gradually appear condensed water in the breathing tube connected to the main unit outlet due to the temperature difference between the ambient temperature and the airflow temperature in the tube. When the temperature difference is large, the amount of condensed water gradually increases. When the patient sits up or has other actions to instantly raise the breathing tube and it is higher than the height of the main unit outlet, the condensed water will flow back to the main unit outlet. If the snoring sound collection point is not set reasonably, the backflow of condensed water will easily flow into the snoring sound collection point, causing the collection channel to be blocked, resulting in the failure of the collection function. Utility Model Content

[0005] The purpose of the utility model is to overcome the problem in the prior art that the snoring sound collection channel of the ventilation therapy equipment is easily blocked by condensed water, resulting in failure of the collection function, and to provide a snoring sound collection auxiliary unit, which can effectively prevent moisture from entering the collection through hole, avoid failure of the collection function due to blockage of the snoring sound collection channel by condensed water, thereby improving the performance of the equipment and the safety of use.

[0006] In order to achieve the above-mentioned purpose, the utility model provides, on the one hand, a snoring sound collection auxiliary unit for a ventilation therapy device, comprising a unit body that can be installed in a device host of the ventilation therapy device, the unit body forming a collection transmission channel, the two ends of the collection transmission channel having a first collection channel opening and a second collection channel opening, when the unit body is installed to the device host, the first collection channel opening is close to the host air outlet side of the device host, and the second collection channel opening surrounds the collection through hole on the device host and makes the side of the unit body where the second collection channel opening is located sealed and fit with the device host.

[0007] Preferably, there is an angle of 90° between the opening directions of the first collecting channel opening and the second collecting channel opening.

[0008] Preferably, the unit body is formed with a collection point opening located on the side where the first collection channel opening is located and connected to the first collection channel opening. When the unit body is installed to the device host, the first collection channel opening is connected to the gas delivery channel near the host outlet through the collection point opening.

[0009] Further preferably, the unit body is formed with a water storage groove located on the side where the first collection channel opening is located, and the lower edge of the unit body corresponding to the first collection channel opening and the collection point opening is recessed downward and inward to form the water storage groove, and when the unit body is installed to the device host, condensed water generated at the collection point opening and the first collection channel opening is allowed to enter the water storage groove.

[0010] Preferably, the side wall of the water storage groove away from the collection point opening is arranged as an inclined flow guiding structure.

[0011] Preferably, the lower edge of the opening of the first collection channel is higher than the lower edge of the opening of the collection point.

[0012] Preferably, the unit body is formed with a sealing rib located on a side where the opening of the second collection channel is located, and the sealing rib surrounds the opening of the second collection channel so as to be able to seal and fit with the device host.

[0013] Preferably, the unit body is also formed with a positioning and mounting structure for positioning and cooperating with the device host.

[0014] Preferably, the unit body is an integrally molded silicone piece.

[0015] The second aspect of the utility model provides a ventilation therapy device, comprising a device host and the above-mentioned snoring sound collection auxiliary unit, the device host has a mounting platform formed with the above-mentioned collection through hole, and the snoring sound collection auxiliary unit is installed on the mounting platform.

[0016] Preferably, the device host is provided with a baffle located between the snoring sound collection auxiliary unit and the host air outlet.

[0027] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0028] In the present invention, unless otherwise specified, directional words such as "up, down, left, right" generally refer to up, down, left, right as shown in the reference drawings; "inside and outside" refer to inside and outside relative to the outline of each component itself.

[0029] Reference Figures 1 to 6 As shown, one aspect of the utility model provides a snoring sound collection auxiliary unit 1 for a ventilation therapy device, the snoring sound collection auxiliary unit 1 includes a unit body, which can be installed in the device host 2 of the ventilation therapy device. Among them, a collection transmission channel 11 is formed in the unit body of the snoring sound collection auxiliary unit 1, and the two ends of the collection transmission channel 11 have a first collection channel opening 11a and a second collection channel opening 11b. When the snoring sound collection auxiliary unit 1 is installed in the device host 2, the first collection channel opening 11a serves as the input end of the collection transmission channel 11, and the first collection channel opening 11a is close to the host air outlet 21 of the device host 2, so that the collection through hole 22 connected to the collection transmission channel 11 can collect the sound wave signal as close to the patient's use end as possible, thereby improving the accuracy of the snoring sound collection data at the patient's use end. Specifically, the airflow of the ventilation therapy device is transmitted to the main unit outlet 21 after being heated and humidified by the humidification tank (not shown), and then the heated and humidified gas is transmitted to the patient's end through the breathing tube connected to the main unit outlet 21. Therefore, the first collection channel opening 11a is connected to the breathing gas delivery channel between the humidification tank and the main unit outlet 21. The second collection channel opening 11b serves as the output end of the collection transmission channel 11, which surrounds the collection through hole 22 on the device main unit 2 and makes the side where the second collection channel opening 11b is located seal and fit with the device main unit 2.

[0030] Therefore, when the snoring sound collection auxiliary unit is installed on the device host of the ventilation therapy device, the collection through hole 22 on the device host 2 is connected to the respiratory gas delivery channel between the humidification tank and the host outlet 21 through the collection transmission channel 11. The snoring sound fluctuations in the respiratory gas delivery channel can be transmitted to the sound wave sensor device in the collection through hole 22 through the collection transmission channel 11, thereby realizing real-time collection of the sound wave pressure close to the patient's use end, so as to accurately monitor the user's snoring status.

[0031] Since the second collection channel opening 11b facing the collection through hole 22 surrounds the collection through hole 22, and the unit body is sealed and fitted with the device host 2 on this side, the collection transmission channel 11 is formed into a structure similar to a blind cavity with one end open (the first collection channel opening 11a is connected to the outside world) and the other end closed (the second collection channel opening 11b is sealed on the surface of the device host 2). When the airflow in the respiratory gas delivery channel is in a stable state, the internal and external forces formed by the collection transmission channel 11 at the first collection channel opening 11a are balanced, and the humid and hot airflow in the respiratory gas delivery channel will not enter the collection transmission channel 11. When there is an impact airflow fluctuation in the respiratory gas delivery channel, the collection transmission channel 11 with a blind cavity structure will instantly generate a force to resist the airflow that fluctuates to the first collection channel opening 11a to enter it, thereby hindering the humid and hot airflow from entering the collection transmission channel 11, thereby effectively preventing the collection through hole 22 from being blocked by condensed water formed by the humid and hot airflow, ensuring the high reliability and safety of the snoring sound collection function.

[0032] Figures 4 to 6 The structure of a snoring sound collection auxiliary unit 1 of a preferred embodiment of the utility model is shown from different perspectives. It is generally in the shape of a rectangular parallelepiped and can be detachably installed to the device host 2 in a plug-in manner, which will be described in detail later. In order to further reduce the risk of condensed water formed by the humid and hot air flow entering the collection through hole 22, the collection transmission channel 11 can be set along a non-straight path. In the preferred embodiment shown in the figure, there is a 90° angle between the opening directions of the first collection channel opening 11a and the second collection channel opening 11b, wherein the first collection channel opening 11a opens to the side, and the second collection channel opening 11b opens to the bottom.

[0033] In a preferred embodiment of the present invention, the unit body of the snoring sound collection auxiliary unit 1 is further formed with a water storage groove 12 disposed below the first collection channel opening 11a. When there is a large airflow impact or in a high humidity environment, and the ambient temperature is low, condensed water is easily generated at the first collection channel opening 11a, and this part of condensed water can flow to the water storage groove 12 for temporary storage. In this way, it is effectively prevented that condensed water accumulates and enters the collection transmission channel 11 to cause the collection through hole to be blocked, which is conducive to reliably achieving the purpose of waterproofing.

[0034] In a more preferred embodiment of the present utility model, the unit body of the snoring sound collection auxiliary unit 1 can also be formed with a collection point opening 13. When installed to the device host 2, the first collection channel opening 11a is connected to the respiratory gas delivery channel through the collection point opening 13. In the illustrated embodiment, the collection point opening 13 is adjacent to the first collection channel opening 11a and the water storage groove 12 respectively, so that condensed water generated during the flow of moisture from the collection point opening 13 to the first collection channel opening 11a can enter the water storage groove 12. Among them, the collection point opening 13 can be formed to be open on one side facing the water storage groove 12, so as to form an airflow channel by fitting with the device host 2. Through this arrangement, the snoring sound collection auxiliary unit 1 of the present utility model can be conveniently formed by injection molding and the like. For example, the snoring sound collection auxiliary unit 1 can be integrally injection molded from a silicone material.

[0035] The water storage groove 12 can be regarded as a depression between the outer wall of the unit body located below the collection point opening 13 and the side wall formed by a distance inward from the outer wall. Further, in order to facilitate the guidance of the condensed water at the first collection channel opening 11a and the collection point opening 13 to enter the water storage groove 12 as much as possible, the side wall of the water storage groove 12 away from the collection point opening 13, that is, the side wall away from the outer wall of the unit body, can be set to be inclined relative to the outer wall of the unit body, forming an inclined guide structure 121. As a result, the condensed water at the first collection channel opening 11a and the collection point opening 13 can be conveniently drained into the water storage groove 12.

[0036] like Figure 4 As shown, the upper edge of the first collection channel opening 11a is set to be flush with the upper edge of the collection point opening 13, while the lower edge 111 of the first collection channel opening (i.e., the edge close to the water storage groove 12) is higher than the lower edge 131 of the collection point opening, thereby facilitating the guidance of condensed water into the water storage groove 12 and reducing the risk of condensed water entering the collection and transmission channel 11.

[0037] As mentioned above, the snoring sound collection auxiliary unit 1 of the utility model is sealed and fitted with the device host 2 through its unit body on the side where the second collection channel opening 11b is located, so that the collection transmission channel 11 is a blind cavity structure to resist airflow entering therein and achieve a good waterproof effect. To this end, the unit body can be formed with a sealing rib 14 located on the side where the second collection channel opening 11b is located, and the sealing rib 14 surrounds the second collection channel opening 11b to be able to seal and fit with the device host 2.

[0038] In addition, in order to facilitate the stable installation of the snoring sound collection auxiliary unit 1 on the device host 2 and ensure a sealed fit with the device host 2, a positioning installation structure for positioning and matching with the device host 2 can be formed on the unit body. In the preferred embodiment shown in the figure, positioning grooves 15 are formed on both sides of the unit body, and positioning protrusions 25 that match the positioning grooves 15 are correspondingly formed on the device host 2. In the case where the snoring sound collection auxiliary unit 1 is made of silicone material, for example, it can be configured with the device host 2 to form an interference fit between soft and hard materials to ensure stable installation and sealed fit.

[0039] Another aspect of the utility model provides a ventilation therapy device, comprising a device host 2 and the above-mentioned snoring sound collection auxiliary unit 1, wherein the device host 2 has a mounting platform 23 formed with a collection through hole 22, and the snoring sound collection auxiliary unit 1 is installed on the mounting platform 23, and the second collection channel opening 11b surrounds the collection through hole 22, and the side where the second collection channel opening 11b is located is sealed and fitted with the device host 2.

[0040] In order to reliably collect the user's snoring signal, the snoring sound collection auxiliary unit 1 usually needs to be as close to the main unit air outlet 21 as possible to obtain accurate snoring fluctuations, so as to facilitate its transmission to the pressure sensor for collecting sound wave pressure on the control circuit main board located near the collection through hole 22. However, being close to the main unit air outlet 21 will increase the risk of condensed water flowing back from the respiratory duct entering the snoring sound collection auxiliary unit 1. In this regard, in a ventilation therapy device of a preferred embodiment of the utility model, the device main unit 2 is provided with a baffle 24 located between the snoring sound collection auxiliary unit 1 and the main unit air outlet 21, which can shield part of the structure of the snoring sound collection auxiliary unit 1, so as to prevent the liquid from directly entering the collection transmission channel 11 of the snoring sound collection auxiliary unit 1 when the condensed water in the respiratory duct flows back, or the liquid splashes and vibrates to the wall near the main unit air outlet 21 where the snoring sound collection auxiliary unit 1 is installed, and then flows back into the collection transmission channel 11, thereby effectively ensuring the penetration of the collection through hole and the effectiveness of the snoring sound collection function.

[0041] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, including the combination of various specific technical features in any suitable manner. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations. However, these simple modifications and combinations should also be regarded as the contents disclosed by the present invention and belong to the protection scope of the present invention.
