Features and advantages of embodiments of the present invention will become apparent with reference to the following detailed description and drawings, in which:

fig. 1 shows a schematic perspective view of an oxygen therapy cabin according to an exemplary embodiment of the present invention.

Detailed Description

The technical scheme of the invention is further specifically described by the following embodiments and the accompanying drawings. The following description of the embodiments of the present invention with reference to the accompanying drawings is intended to explain the general inventive concept and should not be construed as limiting the invention.

Furthermore, in the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the embodiments. It may be evident, however, that one or more embodiments may be practiced without these specific details. In order to simplify the drawings, well-known structures and devices are not shown in the drawings.

According to an exemplary embodiment of the present invention, an oxygen therapy cabin, or an oxygen-enriched health preserving cabin, is provided, which is an atmospheric pressure environment device with an internal pressure higher than the standard atmospheric pressure. Based on 'Henry's law, when the human body is placed in the cabin body higher than the standard atmospheric pressure, a large amount of oxygen is dissolved in the blood to realize the oxygen therapy effect, so that the oxygen therapy cabin of the invention does not need to supply pure oxygen, is safer and saves the cost. Specifically, an exemplary embodiment of the present invention provides an oxygen therapy cabin including a cabin body 1, an air intake system 2, an air exhaust system 3, and a control system, wherein the cabin body 1 is configured to accommodate at least one user; the air inlet system 2 is used for conveying air into the cabin; an exhaust system 3 connected to the chamber body for exhausting gas from the chamber body; the control system is configured to control the intake system 2 and the exhaust system 3 to realize a pressurization process and a pressure release process and a pressure maintenance process; and the control system is further configured to enable the user to make one or more of the following selections: the pressure control device is configured to select one of at least three operating pressures, one of at least three operating durations, one of at least three pressurization speeds, or one of at least three pressure relief speeds.

Due to differences in gender, age, fitness, personal preference, etc., of users of the oxygen therapy cabin, different requirements may be imposed on the cabin internal pressure, the recuperation time, the pressurization speed, the pressure release speed, for example, an excessively fast pressurization speed or pressure release speed may cause discomfort for some users, and a lower cabin internal pressure or recuperation time may be required for some infirm users. In the above exemplary solution, the control of the intake system 2 and the exhaust system 3 by the control system enables the user to have multiple options, namely, to select one of at least three operating pressures, one of at least three operating periods, one of at least three pressurization speeds, or one of at least three pressure relief speeds, so as to better meet the diversified needs of the user and increase the comfort thereof.

As an example, the operating period may be provided with a plurality of gears for selection by the user, for example three gears, for example 30min/60min/90 min. The operating pressure may be provided with three gears for the user to select: 1.2/1.25/1.3 times atmospheric pressure. The pressurizing or pressure releasing speed can also be respectively set to three gears: fast/normal/slow. Those skilled in the art will appreciate that the above-mentioned setting of each gear is only an example, and different numbers of gears or corresponding gear parameters may be set according to requirements.

Preferably, the cabin 1 of the present invention is designed to accommodate a plurality of persons. The height of the hatch 6 may be designed to be substantially upright for adult access. Therefore, the cabin body has high and spacious appearance, people are not easy to generate closed phobia in the cabin body, and users can move and get in and out conveniently.

As an example, the outer shell of the nacelle 1 is formed by splicing at least three sections, and the nacelle further comprises a sealing member disposed between the joints of adjacent sections. In this solution the cabin is assembled from several sections, thereby facilitating transport and storage of the components. Further, the number of the sections can be flexibly selected according to requirements to form different cabin body lengths so as to form oxygen therapy cabins with different containing volumes.

Since the breathing of the personnel in the cabin during the pressurization process, such as several minutes or even tens of minutes or longer, increases the concentration of carbon dioxide in the air in the closed cabin, and the air is not fresh enough to cause the experience of the personnel therein to be poor, in the embodiment of the present invention, not only the intake system 2 but also the exhaust system 3 are operated during the pressurization process to realize ventilation. The present invention thus provides an example of a control system configured to: controlling the operation of both the intake system 2 and the exhaust system 3 during the pressurization process. So that venting to expel carbon dioxide can also be performed during pressurization. As an example, the control system may be configured to control the intake system 2 and the exhaust system 3 during the pressurization process such that intake and exhaust occur simultaneously but at different speeds, wherein the intake speed of the intake system 2 is greater than the exhaust speed of the exhaust system 3, while the pressurization process is being carried out while air freshening is ensured. However, it will be appreciated by those skilled in the art that the control system may be arranged in other ways as desired, for example such that the exhaust system 3 is operated intermittently or periodically, or such that the exhaust system 3 is operated after a certain period of time after the start of the pressurisation process.

Similarly, the control system is configured such that both the intake system 2 and the exhaust system 3 are controlled to operate during the pressure relief process. Illustratively, the air intake system 2 and the air exhaust system 3 may be controlled such that air intake and air exhaust occur simultaneously but at different rates, where the air intake rate of the air intake system 2 is less than the air exhaust rate of the air exhaust system 3 to ensure air freshening while achieving a pressure relief process.

Further, the control system is configured such that the air intake system 2 and the exhaust system 3 are both controlled to operate during the pressure maintenance process to maintain a dynamic balance of the pressure within the cabin. For example, the intake and exhaust may be made to occur simultaneously and the intake and exhaust speeds set separately as needed. By the scheme, after the pressurization process is finished, the air inlet system is not simply closed, but the air inlet operation and the air exhaust operation are carried out to keep the dynamic balance of the pressure in the cabin body, so that the oxygen therapy pressure and the oxygen therapy effect are ensured, and the freshness of air is kept.

According to one example, in order to prevent "short-circuiting" of fresh gas, i.e. to prevent air from entering and then being directly expelled without diffusing in the cabin, air inlets and air outlets may be placed at the cabin head and the cabin tail, respectively.

According to one example, the control system comprises a PLC controller to control the air intake system 2 and the exhaust system 3.

Preferably, the control system comprises a touch screen 5, wherein the user selects each gear of the working pressure, the working duration, the pressurization speed and the pressure relief speed by operating the touch screen. As an example, there are two touch screens respectively located inside the cabin 1 and outside the cabin 1, so as to facilitate operations by cabin personnel or operations by cabin personnel. Preferably, the two touch screens are independently operable and controllable. The two touch screens can also be given different operating rights.

Further, a pressure sensor may be arranged in the cabin 1 and communicatively connected to the control system. Advantageously, the pressure profile in the cabin monitored by the pressure sensor is dynamically displayed by the touch screen. Therefore, the change process of the pressure in the cabin can be intuitively displayed on the touch screen, and the air inlet system 2 and the air outlet system 3 can be coordinately controlled according to the needs to realize the expected pressure change curve in the cabin. For example, the pressurization speed and the depressurization speed are kept to be linearly changed, or the pressure is kept constant. Alternatively, a separate display may be provided to display the time profile of the pressure in the cabin.

As an example, the air intake system 2 of the oxygen therapy cabin may comprise at least two sets of air intake devices, each set being capable of achieving the at least three pressurization speeds. More air intake devices are turned on when a faster pressurization rate is desired, and vice versa when a slower pressurization rate is desired.

Similarly, the exhaust system 2 comprises at least two sets of electrically powered exhaust devices to achieve the at least three pressure relief rates.

As an example, each set of air intake means comprises a pump 21 and an air intake line 23, wherein the pump 21 is used to provide the gas and the air intake line 23 is used to convey said gas; and the control system comprises an inlet solenoid valve 22, arranged on the inlet line, for controlling the supply of the gas.

Preferably, the oxygen therapy cabin further comprises an air inlet filtering system arranged at an air inlet of the pump 21 of the air inlet device. The air inlet filtering system can filter air and can realize various filtering functions according to requirements, such as filtering fine particles and purifying the air entering the cabin.

A muffler 24 may be provided at the air inlet where the air inlet line 23 connects to the cabin 1. A muffler may be provided in the exhaust line 31. The noise in the air intake and exhaust process can be reduced by the means.

Preferably, in order to realize the manual pressure relief of the oxygen therapy cabin when the emergency condition of the health preserving cabin occurs, such as in a power-off state, a manual pressure relief valve is arranged. The manual pressure relief valve can be provided in a plurality of numbers according to requirements, for example, at different positions of the cabin body, for example, on the head and tail sections at two ends of the cabin body, so as to realize pressure relief by fast operation in emergency.
