Description

Technical Field

[0001] The utility model relates to the technical field of hyperbaric oxygen therapy, in particular to a wearable hyperbaric oxygen therapy system. Background Art

[0002] Hyperbaric oxygen therapy is a treatment method that implements intermittent breathing of 100% oxygen for patients under conditions equal to or greater than 1 absolute atmospheric pressure. Hyperbaric oxygen therapy effectively improves the bioavailability of oxygen in human tissues by increasing the environmental pressure. It also has clinical effects such as antibacterial, immunomodulatory and angiogenesis, and is therefore suitable for many hypoxic or ischemic source, secondary and related diseases, including various types of harmful gas poisoning, cerebral thrombosis, cerebral hemorrhage, brain trauma, neuritis, vasculitis, diabetic gangrene, difficult-to-heal ulcers, fetal maldevelopment, neonatal asphyxia, acute gas embolism, decompression sickness, altitude sickness, sudden deafness, Meniere's syndrome, vertigo, etc.

[0003] Hyperbaric oxygen therapy is carried out clinically by using a hyperbaric oxygen chamber. The basic principle of a hyperbaric oxygen chamber is a cabin based on an integrated space, which forms a high-pressure environment inside and outside the patient's respiratory system by accommodating the patient's entire body. In addition to functions such as air pressure control and safety assurance, hyperbaric oxygen chambers generally have basic characteristics such as large size, heavy weight, complex structure, and difficulty in moving, which also makes it difficult for medical staff to perform various necessary close operations on patients. In recent years, one of the technical improvements of hyperbaric oxygen chambers is to reduce the size and weight of the cabin, involving a variety of technical improvements, such as flexible material frame type (CN218247660U), folding type (e.g. CN117338547A), soft shell type (CN218685049U), hard shell type (CN219963325U), etc. However, the basic form of various technologies is still an integrated cabin that accommodates the patient's entire body, and the volume and weight are difficult to reduce further; and the patient's entire body (head and neck, trunk, upper limbs and lower limbs) is completely covered, and the high-pressure and oxygenated environment in the cabin has not changed the restrictions on close medical operations. Utility Model Content

[0004] The purpose of the utility model is to solve the problems in the prior art and to propose a wearable hyperbaric oxygen therapy system, which only applies a high-pressure environment to the patient's head, neck and trunk, but not to the upper and lower limbs, making it convenient for medical staff to perform close medical care operations on the patient's upper and lower limbs.

[0016] As a further solution of the utility model: the linkage controller is configured as a PLC controller or a single chip microcomputer.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] 1. Compared with the traditional hyperbaric oxygen chamber in the prior art, the utility model provides a breathing mask and a pressure suit. The breathing mask is used to wrap the patient's respiratory tract and external auditory canal to form an airtight space. By supplying high-pressure oxygen to the airtight space of the breathing mask, a stable pressure environment can be formed on the one hand, and oxygen can be provided to the patient on the other hand; the pressure suit is used to wrap the patient's torso to provide a stable pressure environment for the patient's torso; through this arrangement, the patient's upper limbs and lower limbs can be exposed, and in the subsequent oxygen therapy process, medical staff can perform medical operations on the patient's upper limbs or lower limbs at close range, which is convenient to use;

[0019] 2. At the same time, through the setting of the control module, the control module is used to control the amount of high-pressure oxygen supplied by the air supply module to the airtight space and the air storage layer of the pressure suit, so that the airtight space and the air storage layer of the pressure suit maintain the same pressure, and then the pressure on the patient's head, neck and trunk remains the same, which is convenient for better high-pressure oxygen therapy;

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] like Figure 1-Figure 2 As shown, a wearable hyperbaric oxygen therapy system is different from the treatment method using a hyperbaric oxygen chamber in the prior art. The hyperbaric oxygen therapy system applies a high-pressure environment to the respiratory tract, external auditory canal and trunk of the patient's head, so that in the subsequent oxygen therapy process, medical staff can perform medical operations on the patient's upper limbs or lower limbs at close range, which is convenient to use. Specifically, the hyperbaric oxygen therapy system in the utility model includes a breathing mask 1, a pressure suit 2 and an air supply module 3, wherein: the breathing mask 1 is used to wrap the patient's respiratory tract and external auditory canal to form an airtight space, the pressure suit 2 is used to wrap the patient's trunk to apply a stable pressure environment to the patient's trunk, the pressure suit 2 has an air storage layer, and the air supply module 3 is used to supply oxygen and safety gas to the airtight space and the air storage layer of the pressure suit 2 respectively. During the process of high-pressure oxygen therapy, the air supply module 3 can be used to supply high-pressure oxygen to the airtight space formed by the breathing mask 1, and the air supply module 3 can be used to supply safe high-pressure gas to the gas storage layer of the pressure suit 2. The high-pressure gas can be high-pressure oxygen or other safety gases in the prior art, so that the pressure inside the airtight space and the gas storage layer meets the requirements of oxygen therapy.

[0031] During the physical therapy process, by supplying high-pressure oxygen into the airtight space of the breathing mask 1, on the one hand, a stable pressure environment can be formed, and on the other hand, oxygen can be provided to the patient; at the same time, the high-pressure oxygen in the airtight space can balance the pressure between the oropharynx and the external auditory canal, preventing the patient from being injured due to the pressure difference between the inside and outside of the eardrum.

[0032] Regarding the setting of the air supply module 3, the air supply module 3 can be a high-pressure oxygen supply machine in the prior art, etc. Of course, this embodiment is not limited to setting the air supply module as a high-pressure oxygen supply machine, as long as it can achieve the corresponding high-pressure oxygen supply function. In order to avoid cumbersome writing, this article will not go into details here. This embodiment will be described later by taking the supply of high-pressure oxygen to the airtight space and the air storage layer of the pressure suit 2 as an example. Regarding the setting of the air supply module 3 supplying high-pressure oxygen to the airtight space and the air storage layer of the pressure suit 2, a pipeline 4 can be set, and the airtight space and the air storage layer of the pressure suit 2 are connected to the air supply module 3 through the pipeline 4. Through the pipeline 4, the air supply module 3 can supply high-pressure oxygen to the inside of the airtight space and the air storage layer.

[0033] Furthermore, in order to control the on-off of the pipeline 4, an air charging valve 5 can be provided on the pipeline 4, and the on-off of the pipeline 4 can be controlled by the air charging valve 5. At the same time, after the completion of the high-pressure oxygen therapy, in order to quickly discharge the high-pressure oxygen in the airtight space and the gas storage layer, an exhaust valve 6 for deflation can be provided on the gas storage layer of the breathing mask 1 and the pressure suit 2.

[0034] During actual use, in order to intelligently control the airtight space and the air storage layer to always dynamically maintain the same pressure, the utility model can be configured to also include a control module, which is used to control the amount of high-pressure oxygen supplied by the air supply module 3 to the airtight space and the air storage layer of the pressure suit 2, so that the airtight space and the air storage layer of the pressure suit 2 maintain the same pressure.

[0035] Specifically, for the setting of the control module mentioned above, the control module includes a linkage controller 7 and an air pressure sensor 8 arranged inside the air storage layer of the breathing mask 1 and the pressure suit 2. The air pressure sensor 8 is electrically connected to the linkage controller 7, and the inflation valve 5 and the exhaust valve 6 are both electrically connected to the linkage controller 7 and controlled by the linkage controller 7. After the breathing mask 1 and the pressure suit 2 are wrapped in the corresponding position of the patient, the air supply module 3 can be used to supply high-pressure oxygen to the airtight space and the air storage layer, the inflation valve 5 is opened, and the exhaust valve 6 is closed. During this process, the air pressure sensor 8 located inside the airtight space and the air storage layer will always monitor the pressure inside it. When the pressure inside the airtight space or the air storage layer reaches the preset requirement, the air pressure sensor 8 will transmit a signal to the linkage controller 7, and the linkage controller 7 controls the corresponding inflation valve 5 to close. At the same time, in the subsequent high-pressure oxygen therapy process, under the preset pressure requirement, the linkage controller 7 can control the corresponding inflation valve 5 and the exhaust valve 6 to open or close to meet the stable pressure environment formed by the airtight space and the air storage layer.

[0036] Regarding the setting of the above-mentioned linkage controller 7, the linkage controller 7 can be any suitable computing device, such as a personal computer, a server, a programmable controller (PLC controller for short), a single-chip microcomputer, etc., or it can be an integration of computer devices. The linkage controller 7 has functions such as receiving information and sending control commands. The linkage controller 7 can control the inflation valve 5 and the exhaust valve 6 to perform corresponding actions through wired communication or wireless communication to meet the formation and elimination of the stable pressure environment inside the airtight space and the gas storage layer.

[0037] like Figure 1 As shown, in order to better monitor the pressure in the airtight space and the gas storage layer, the air pressure sensor 8 inside the breathing mask 1 can be set to multiple, the air pressure sensor 8 located in the gas storage layer can be set to multiple, and the multiple air pressure sensors 8 at the corresponding positions can be evenly arranged. Figure 2 As shown, in order to ensure that the pressure suit 2 applies a uniform pressure-stabilizing environment to the patient, the air storage layer of the pressure suit 2 may be composed of a plurality of interconnected air bags 201 , and the plurality of air bags 201 may be uniformly distributed on the pressure suit 2 .

[0038] In order to satisfy the use of different patients, the breathing mask 1 in this embodiment can be set to a head mask or a face mask, and fixed to the patient's face through elastic ear straps and a back head strap. Figure 1 The situation that the breathing mask 1 is set as a head cover type is shown in FIG. Meanwhile, in order to enhance the sealing property and wearing comfort of the breathing mask 1, plastic material is adopted and flexible sealing material is adopted at the contact point with the skin.

[0039] It should be noted that the pressure of the gas storage layer of the pressure suit 2 is approximately equal to the pressure on the surface of the patient's torso, because the pressure is mutual and the force-bearing area is the same, so the pressure is also the same. Compared with directly measuring the pressure on the surface of the torso, it is more convenient to measure the pressure in the gas storage layer of the pressure suit 2.

[0040] like Figure 3-Figure 4 As shown, the steps for using the hyperbaric oxygen therapy system are as follows:

[0041] (1) Phase 1, inflation and pressure increase. First, the airtight space formed by the breathing mask 1 and the internal pressure of the air storage layer of the pressure suit 2 are preset to P0. In the initial state, the inflation valve and exhaust valve of the breathing mask 1 and the pressure suit 2 are both in the closed state. Then, under the control of the linkage controller 7, the air storage layer of the pressure suit 2 and the airtight space formed by the breathing mask 1 are inflated at the same time. At this time, the pressure inside the airtight space formed by the breathing mask 1 is Pmask, and the pressure inside the air storage layer of the pressure suit 2 is Psuit. When the difference between P0 and Pmask is zero, the linkage controller 7 executes a hold instruction, so that the inflation valve and exhaust valve corresponding to the breathing mask 1 are both closed; when the difference between P0 and Pmask is greater than zero, the linkage controller 7 executes an inflation instruction, so that the inflation valve corresponding to the breathing mask 1 is opened and the exhaust valve is closed; when P0 and Pmask are equal to zero, the linkage controller 7 executes a hold instruction, so that the inflation valve and exhaust valve corresponding to the breathing mask 1 are opened and the exhaust valve is closed; when P0 and Pmask are equal to zero, the linkage controller 7 executes a hold instruction, so that the inflation valve and exhaust valve corresponding to the breathing mask 1 are opened and the exhaust valve is closed. 罩 When the difference between P0 and Psuit is less than zero, the linkage controller 7 executes a deflation instruction, so that the inflation valve corresponding to the breathing mask 1 is closed and the exhaust valve is opened. When the difference between P0 and Psuit is equal to zero, the linkage controller 7 executes a hold instruction, so that the inflation valve and exhaust valve corresponding to the air storage layer of the pressure suit 2 are both closed; when the difference between P0 and Psuit is greater than zero, the linkage controller 7 executes an inflation instruction, so that the inflation valve corresponding to the air storage layer of the pressure suit 2 is opened and the exhaust valve is closed; when the difference between P0 and Psuit is less than zero, the linkage controller 7 executes a deflation instruction, so that the inflation valve corresponding to the air storage layer of the pressure suit 2 is closed and the exhaust valve is opened. After the inflation is completed, the internal pressure of the airtight space formed by the air storage layer of the pressure suit 2 and the breathing mask 1 is consistent, both of which are P0, that is, the pressure after the inflation is completed is not less than 1 absolute atmosphere, or it is inflated to a specified pressure according to clinical needs.

[0042] (2) Stage 2: Constant-pressure oxygen therapy. Under the condition that the internal pressure of the airtight space formed by the gas storage layer of the pressure suit 2 and the breathing mask 1 is consistent and stable, the patient continues oxygen therapy for one hour, or the treatment time is specified according to clinical needs.

[0043] (3) Phase 3: venting and reducing pressure. Under the control of the linkage controller 7, the corresponding exhaust valve is controlled to operate to discharge the gas inside the airtight space formed by the air storage layer of the pressure suit 2 and the breathing mask 1. During this process, the gas inside the airtight space formed by the air storage layer of the pressure suit 2 and the breathing mask 1 is controlled to be discharged evenly. During the discharge process, the pressure inside the two is kept dynamically consistent until the pressure inside the two is consistent with the atmospheric environment.

[0044] (4) After the oxygen therapy is completed, the gas supply module 3 is turned off, and the pipeline 4 as well as the pressure suit 2 and the breathing mask 1 on the patient are removed.

[0045] The control flow of the above stages can be represented by Figure 3 and Figure 4 To represent it, the parts are marked as follows:

[0046] P0 is the preset pressure, not less than 100kPa;

[0047] P mask is the pressure inside the airtight space formed by the breathing mask 1;

[0048] Psuit is the pressure inside the gas reservoir of pressure suit 2;

[0049] The monitoring unit is an air pressure sensor;

[0050] The action unit is a linkage controller.

[0051] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
