Description

Technical Field

[0001] The utility model relates to a ventilation therapy device, in particular to an elastic support structure. On this basis, the utility model also relates to a ventilation therapy device with the elastic support structure. Background Art

[0002] In modern clinical medicine, ventilation therapy equipment such as ventilators are often used for respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support therapy and emergency resuscitation. In order to provide patients with suitable gases, ventilators are usually equipped with a water tank so that the air is heated and humidified when flowing through the water tank to ensure that the patient has a good breathing experience. When in use, the water tank is installed in the device body (host housing), and a heating plate is arranged below it. The bottom of the heating plate is supported by an elastic support structure to keep the heat transferred to the heat conducting plate at the bottom of the water tank to achieve the purpose of heating and humidification.

[0003] The existing elastic support structure of the heating plate mainly includes a spring-type or a shrapnel-type structure. However, after long-term pressure, the spring-type and shrapnel-type elastic support structures made of metal materials will undergo plastic deformation, resulting in an inability to reliably elastically support the heating plate. In addition, such elastic support structures are prone to corrosion after long-term use in high temperature and high humidity environments, and thus there is a problem of uncontrollable corrosion damage areas, resulting in uneven and unstable elastic support force on the heating plate, affecting the heat transfer effect from the heating plate to the water tank. In addition, when squeezed by the heating plate, the spring-type or shrapnel-type elastic support structure undergoes elastic deformation to store elastic potential energy, but this deformation is easily affected by the relative movement direction of the heating plate, resulting in unstable and uneven elastic support force applied to the heating plate. Utility Model Content

[0004] The purpose of the utility model is to overcome the problem in the prior art that the elastic supporting structure cannot stably support the target component such as a heating plate, and to provide an elastic supporting structure that can be relatively controllably extruded and deformed under the downward extrusion of the target component, thereby avoiding the problem of uneven and unstable elastic supporting force of the reverse supporting target element caused by uncertain tipping direction, thereby effectively ensuring the supporting effect.

[0005] In order to achieve the above-mentioned objectives, the utility model provides, on the one hand, an elastic support structure for supporting a target component, and includes a hollow elastic support unit abutting against the target component, the hollow elastic support unit protrudes toward the target component so that the top of the protrusion abuts against the target component, and a cavity is formed on the side away from the target component.

[0006] Preferably, the hollow elastic support unit is configured to be elastically deformable along a center line of the cavity perpendicular to the target component under the pressure of the target component.

[0007] Preferably, the elastic support structure comprises at least two hollow elastic support units symmetrically arranged corresponding to the edge of the target component.

[0008] Preferably, the hollow elastic supporting unit is made of silicone material.

[0009] Preferably, the hollow elastic supporting unit is formed in an arch bridge shape, a hemispherical shape, a flat-topped cone shape, a cube shape, a bellows shape or a circular ring shape protruding toward the target component.

[0010] Preferably, the elastic support structure comprises a support structure main body, and a plurality of the hollow elastic support units protrude from the support structure main body toward the target component and form the cavity open toward the target component.

[0011] Preferably, positioning columns for positioning and installation are formed on the supporting structure body.

[0012] Preferably, the elastic supporting structure is an integrated structure.

[0013] Preferably, the elastic supporting structure is made of silicone material.

[0014] Preferably, a water leakage hole extending through the thickness direction is formed on the supporting structure body.

[0015] Preferably, a water collecting groove which is recessed in a direction away from the target component is formed on the side of the supporting structure body facing the target component, and the water leakage hole is connected to the water collecting groove.

[0016] Preferably, a water guide groove which is recessed toward the target component is formed on a side of the support structure body which is away from the target component, and the water leakage hole is connected to the water guide groove.

[0017] Preferably, the water guide groove extends from a position communicating with the water leakage hole to an edge of the supporting structure body.

[0018] The second aspect of the utility model provides a ventilation therapy device, including a device body and a water tank installed on the device body, the device body having a heating plate bottom shell, a heating plate for heating the water tank, and the above-mentioned elastic support structure installed on the heating plate bottom shell for supporting the heating plate.

[0019] Through the above technical scheme, the elastic support structure of the utility model utilizes a hollow elastic support unit protruding toward the target component to be supported to elastically support the target component. Under the downward squeezing action of the target component, the hollow elastic support unit will basically only deform and displace toward the cavity formed on the side away from the target component, while avoiding other deformation modes with uncertain movement directions such as tipping, thereby enabling it to mainly apply elastic supporting force in the direction toward the target component to ensure uniform, stable and good support effect.

[0040] 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.

[0041] Reference Figure 1As shown, the elastic support structure 1 provided by the utility model can be used in a ventilation therapy device such as a ventilator, and the ventilation therapy device can include a device body and a water tank installed on the device body, wherein the device body (host housing) has a heating plate bottom shell 3 and a heating plate 2. When the elastic support structure 1 is applied to the ventilation therapy device, the elastic support structure 1 can be installed on the heating plate bottom shell 3 and elastically supported on the bottom of the heating plate 2, so the heating plate 2 of the ventilation therapy device is equivalent to the target component supported by the elastic support structure 1. Thus, when the water tank is installed in the device body, the heat conducting plate arranged at the bottom of the water tank can receive the heat generated by the heating plate 2 to heat and humidify the gas flowing through the water tank. It can be understood that although the elastic support structure 1 of the utility model will be mainly illustrated here and below with the heating plate 2 in the ventilation therapy device as the supported target component, the elastic support structure 1 can also be used in other devices and elastically support other types of target components.

[0042] Combination Figures 2 to 6 As shown, the elastic support structure 1 according to the first preferred embodiment of the utility model includes a hollow elastic support unit 11 abutting against the heating plate 2, the hollow elastic support unit 11 protrudes toward the heating plate 2 so that the top of the protrusion abuts against the heating plate 2, and a cavity 12 is formed on the side away from the heating plate 2.

[0043] Therefore, when the water tank is installed to sit on the heating plate 2, the hollow elastic support unit 11 abutting against the heating plate 2 can be deformed under the extrusion of the heating plate 2. Since the hollow elastic support unit 11 is configured to form a cavity 12 on the side away from the heating plate 2, the hollow elastic support unit 11 will basically only deform and displace toward the cavity 12, and avoid other deformation modes with uncertain movement directions such as tipping, thereby mainly applying elastic support force in the direction toward the heating plate 2 to ensure uniform, stable and good support effect.

[0044] In the heating plate elastic support structure 1, the hollow elastic support unit 11 is formed into an arch bridge shape protruding toward the heating plate 2. Figure 5 and Figure 6 The cross-sectional structure of the hollow elastic support unit 11 in different directions is shown. It can be seen that the arch bridge shape described here mainly refers to the cross-sectional shape under the PP cross-sectional perspective, and its top surface facing the heating plate 2 is set to an arc shape, and is closed on both sides of the arc-shaped top surface to define the shape of the cavity 12. Therefore, in the initial state, the hollow elastic support unit 11 only abuts the heating plate 2 at the top of the arc; when the water tank is seated on the heating plate 2, the heating plate 2 applies downward pressure on the hollow elastic support unit 11, causing the arc-shaped top surface of the hollow elastic support unit 11 to deform, and the deformation displacement direction is mainly toward the cavity 12 below it.

[0045] Under ideal conditions, since the hollow elastic support unit 11 is configured to have a center line passing through its arc, if the pressure applied by the heating plate 2 acts along the center line, the hollow elastic support unit 11 will deform uniformly along the center line, which effectively improves the controllability of the deformation and the uniformity and stability of the elastic support force applied to the heating plate 2, making it convenient to arrange other components (such as electronic devices of the heating plate 2) in the space adjacent to the hollow elastic support unit 11.

[0046] Generally, according to the shape and size of the heating plate 2, its elastic support structure may include a plurality of hollow elastic support units 11, for example, independent hollow elastic support units 11 may be arranged at the four corners of the rectangular area. The hollow elastic support unit 11 may be set in a circular ring shape to support the circular ring area on the heating plate 2. In order to facilitate positioning and installation, the elastic support structure 1 may include a support structure body 13, and a plurality of hollow elastic support units 11 protrude from the support structure body 13 toward the heating plate 2, and form a cavity 12 open to the back of the heating plate 2. Thus, the heating plate elastic support structure 1 supports the heating plate 2 with a plurality of hollow elastic support units 11, and when the heating plate 2 is pressed downward by force, the hollow elastic support unit 11 is deformed downward, and according to the magnitude of the force, the hollow elastic support unit 11 may be squeezed to be, for example, almost flush with the surface of the support structure body 13, that is, the deformation of the hollow elastic support unit 11 provides space for the movement of the heating plate 2 in the up and down directions, and the cavity 12 provides space for the deformation and displacement of the hollow elastic support unit 11. Furthermore, by forming a plurality of hollow elastic support units 11 and a support structure body 13 into an integrated structure, the heating plate elastic support structure 1 including a plurality of hollow elastic support units 11 can be conveniently installed as a whole on, for example, a heating plate bottom shell 3 by providing a positioning and mounting structure on the support structure body 13, which facilitates processing and improves assembly efficiency.

[0047] More specifically, a positioning column 14 for positioning and installing relative to the heating plate bottom shell 3 can be formed on the support structure body 13, so that the positioning column 14 can cooperate with the positioning structure on the heating plate bottom shell 3 to accurately locate the installation position of the elastic support structure 1.

[0048] In addition, a water leakage hole 15 extending through the thickness direction of the support structure body 13 can be formed, which can avoid problems such as damage to electrical components or breeding of bacteria due to condensation of water vapor on the support structure body 13. At the same time, by providing the water leakage hole 15, it is also possible to prevent the heating plate 2 from being adsorbed on the surface of the support structure body 13 under the action of atmospheric pressure after the water tank is removed, causing the hollow elastic support unit 11 to be unable to rebound. Among them, a water collection groove 16 that is concave away from the heating plate 2 can be formed on the side of the support structure body 13 facing the heating plate 2, and the water leakage hole 15 is connected to the water collection groove 16. Therefore, a groove, i.e., a water collecting groove 16, is provided on the upper surface of the supporting structure body 13 (the "upper surface" may also be referred to as the "front side", and corresponds to the "back side" mentioned below, which are the two surfaces of the supporting structure body 13), and a circular arc guide edge is provided on the edge of the water collecting groove 16, so that water vapor can be collected in the water collecting groove 16 after condensation on the supporting structure body 13, and then discharged outward through the water leakage hole 15, that is, the water in the water collecting groove 16 is flowed out to the side away from the heating plate 2, i.e., the back side of the supporting structure body 13, through the water leakage hole 15. At the same time, the water collecting groove 16 is provided in the area surrounded by multiple hollow elastic support units 11, which can also be used to accommodate electrical components on the bottom side of the heating plate 2 (close to the side of the supporting structure body 13).

[0049] A water guide groove 17 that is concave toward the heating plate 2 may be formed on the side of the supporting structure body 13 that is away from the heating plate 2, that is, the water guide groove 17 is provided on the back of the supporting structure body 13. The water leakage hole 15 may be connected to the water guide groove 17, and extend from the position connected to the water leakage hole 15 to the edge of the supporting structure body 13, thereby facilitating the condensed water leaking from the water leakage hole 15 to be discharged outward along the water guide groove 17.

[0050] In the elastic support structure 1 shown in the figure, at least the hollow elastic support unit 11 is supported by a silicone material, which can be made of a soft rubber material, such as silicone, PET, etc., thereby effectively avoiding the risk of corrosion caused by high temperature and high humidity, and being able to maintain its elastic support effect after long-term use. The top surface of the hollow elastic support unit 11 for abutting the heating plate 2 can be set to have different surface roughnesses as needed to form different pressing effects. Since the cavity 12 can be formed to be open to the back of the heating plate 2, it can be formed by injection molding, molding, etc., and the wall thickness of each part of the entire elastic support structure 1 including the hollow elastic support unit 11 can be set to have a wall thickness of 0.5mm-20mm.

[0051] Figure 7 and Figure 8The elastic support structure 1 according to the second preferred embodiment of the utility model is shown, and the elastic support structure 1 has substantially the same structure and related advantages as the first preferred embodiment described above, and the only difference is that the hollow elastic support unit 11 is formed in a cubic shape. Therefore, in the initial state, the hollow elastic support unit 11 has a top plane in contact with the heating plate 2.

[0052] Fig. 9 and Fig.10 The figure shows an elastic support structure 1 according to a third preferred embodiment of the utility model, which has substantially the same structure and related advantages as the first preferred embodiment, except that the hollow elastic support unit 11 is formed into a hemispherical shape. Thus, in the initial state, the hollow elastic support unit 11 contacts the heating plate 2 at the vertex position, and when the heating plate 2 is subjected to downward pressure, it can be squeezed and deformed uniformly to provide a stable elastic support force to the heating plate 2.

[0053] Fig.11 and Fig.12 The figure shows an elastic support structure 1 according to a fourth preferred embodiment of the utility model, which has substantially the same structure and related advantages as the second preferred embodiment, except that the hollow elastic support unit 11 is formed into a flat-topped cone. Thus, in the initial state, the hollow elastic support unit 11 has a top plane in contact with the heating plate 2, and when the heating plate 2 is subjected to downward pressure, it can be squeezed to deform relatively uniformly, so as to provide the heating plate 2 with a more stable elastic support force.

[0054] Figures 13 to 17 The elastic support structure 1 according to the fifth preferred embodiment of the utility model is shown, and the elastic support structure 1 has substantially the same structure and related advantages as the first preferred embodiment described above, and the only difference is that the hollow elastic support unit 11 is formed in a bellows shape, and the water guide groove 17 is arranged not to extend through the entire width and length of the elastic support structure 1. Among them, the hollow elastic support unit 11 in the bellows shape can effectively ensure that it is stably deformed in a direction perpendicular to the heating plate 2 when being squeezed by the heating plate 2, so that the elastic support force can be applied uniformly and stably.

[0055] On this basis, the utility model also provides a ventilation therapy device including the elastic support structure 1 mentioned above.

[0056] Reference Figure 1As shown, during the installation process, the device body of the ventilation therapy device can be first inverted, and the heating plate 2 can be placed upside down at the installation position of the device body. Then, the heating plate bottom shell 3 with the elastic support structure 1 positioned and installed on the device body can be installed and fixed by fasteners such as screws, so that the hollow elastic support unit 11 of the elastic support structure 1 abuts against the heating plate 2.

[0057] When installing the water tank to the installation position above the heating plate 2, the edge of the heating plate 2 near the water tank insertion port contacts the heat conducting plate at the bottom of the water tank first and moves down first, causing the hollow elastic support unit 11 at the front end of the elastic support structure 1 to deform elastically; when the water tank is fully inserted to the designated position, the edge of the heating plate away from the water tank insertion port contacts the heat conducting plate at the bottom of the water tank, causing the hollow elastic support unit 11 at the rear end of the elastic support structure 1 to deform elastically. Since the hollow elastic support unit 11 has a cavity 12 at the bottom and has good elasticity, it can stably and reliably support the heating plate 2, so that the heating plate 2 always remains in the predetermined position where it can transfer heat to the water tank.

[0058] The elastic support structure 1 made of silicone material can effectively reduce or avoid wear on the resistance wire at the bottom of the heating plate and its electronic components during elastic deformation, effectively protecting the components. Moreover, in a long-term high-temperature heating environment, it will not be oxidized or fail due to environmental humidity, and can effectively block the heat generated by the heating plate to prevent the heat from being transferred to the shell and causing burns to the user.

[0059] The elastic support structure of the utility model has the advantages of simple, stable and compact structure, which effectively reduces the risks of rusting, wear and damage to the heating circuit and electronic components at the bottom of the heating substrate body and machine failure during use, and can also effectively prevent users from being scalded and eliminate safety accidents.

[0060] 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.
