Description

Technical Field

[0001] The present invention relates to the field of medical oxygen inhalation, and more particularly, to an oxygen inhalation device for preventing backflow of condensed water and nasal pressure injury. Background Art

[0002] The development of medicine has deepened people's understanding of oxygen therapy, and the application of oxygen inhalation devices in clinical practice has become more and more extensive. From initially being used to treat some simple respiratory diseases to later playing an important role in multiple fields such as first aid, intensive care, and chronic disease treatment. For example, in the treatment of respiratory failure, carbon monoxide poisoning, cardiopulmonary diseases, etc., oxygen inhalation devices have become important adjuvant treatment means.

[0003] During oxygen inhalation, when oxygen with a relatively high temperature and containing a large amount of water vapor flows out of devices such as a humidifying bottle and enters an oxygen inhalation tube and the surrounding environment with a relatively low temperature, the water vapor will condense into small water droplets when it meets the cold, thus forming condensed water. When the condensed water enters the oxygen inhalation tube or the face mask, it will hinder the normal flow of oxygen, reduce the oxygen concentration inhaled by the patient, affect the effect of oxygen inhalation treatment, and cannot effectively improve the patient's hypoxia condition.

[0004] Therefore, we have made improvements in this regard and proposed an oxygen inhalation device for preventing backflow of condensed water and nasal pressure injury. Summary of the Invention

[0031] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] As described in the background art, when condensate enters the oxygen inhalation tube or the face mask (102), it will hinder the normal flow of oxygen, reduce the oxygen concentration inhaled by the patient, and affect the effect of oxygen inhalation treatment.

[0033] To solve this technical problem, the present invention provides an oxygen inhalation device for preventing condensate backflow and nasal pressure injury, which is applied to collect and discharge condensate during the oxygen inhalation process.

[0034] To enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0035] It should be noted that, without conflict, the embodiments in the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0036] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0037] An oxygen inhalation device for preventing backflow of condensed water and nasal pressure injury includes a housing 101. A mask 102 is fixedly connected to the inner wall of the housing 101. A liquid accumulation box 103 is slidably connected to the lower surface of the mask 102. The liquid accumulation box 103 is fixedly connected to the housing 101. A diversion plate 104 is hinged to the inner wall of the liquid accumulation box 103. A spring 105 is fixedly connected to the outer surface of the diversion plate 104. The other end of the spring 105 is fixedly connected to a sealing plate 106. The sealing plate 106 is slidably connected to the housing 101. A partition plate 107 is hinged to the lower surface of the diversion plate 104. The partition plate 107 abuts against the sealing plate 106. A pull rod 108 is fixedly connected to the surface of the sealing plate 106 away from the spring 105.

[0038] When collecting and discharging condensed water, the pull rod 108 can be pulled. During the pulling process, the pull rod 108 can drive the sealing plate 106 to slide. When the sealing plate 106 slides, on the one hand, it can pull the spring 105 to stretch. When the spring 105 stretches, it drives the diversion plate 104 to rotate. The rotation of the diversion plate 104 conveys the condensed water inside it to the partition plate 107. Since the partition plate 107 abuts against the sealing plate 106, when the sealing plate 106 slides, the partition plate 107 rotates. The partition plate 107 rotates to a horizontal state. At this time, the condensed water on the partition plate 107 drains out along the partition plate 107.

[0039] A breathing mask 201 is fixedly connected to the inner wall of the housing 101 and below the liquid accumulation box 103. An air exchange unit is arranged on the outer surface of the breathing mask 201.

[0040] The breathing mask 201 fixedly connected to the inner wall of the housing 101 and below the liquid accumulation box 103 can seal the patient's oral cavity and nasal cavity for oxygen inhalation. The air exchange unit arranged on the outer surface of the breathing mask 201 is used for the patient to inhale oxygen and exchange air.

[0041] The air exchange unit includes an inhalation valve 301 and an exhalation valve 302. The inhalation valve 301 and the exhalation valve 302 are respectively located on the outer surface of the breathing mask 201. An inhalation chamber 303 is communicated with the outer surface of the inhalation valve 301. An exhalation chamber 304 is communicated with the outer surface of the exhalation valve 302.

[0042] The inhalation valve 301 and the exhalation valve 302 in the ventilation unit are respectively used to connect the inhalation chamber 303 and the exhalation chamber 304. During ventilation, the patient inhales the oxygen in the inhalation chamber 303 through the inhalation valve 301, and then the exhaled gas is discharged to the exhalation chamber 304 through the exhalation valve 302 for gas exchange.

[0043] The inner wall of the breathing mask 201 is fixedly connected with a pressure regulating mask 401, and a groove 402 is arranged inside the pressure regulating mask 401 and fits with the bridge of the nose.

[0044] The pressure regulating mask 401 fixedly connected to the inner wall of the breathing mask 201 is used to closely adhere to the patient's bridge of the nose and replace the oxygen delivery tube with direct inhalation, which can avoid the pressure damage caused by the oxygen delivery tube to the nostrils. In addition, direct inhalation can make the inhaled oxygen more sufficient.

[0045] The inhalation valve 301 and the exhalation valve 302 penetrate through the pressure regulating mask 401 and are located on its inner wall. The inhalation valve 301 and the exhalation valve 302 are symmetric about the pressure regulating mask 401.

[0046] The inhalation valve 301 and the exhalation valve 302 penetrate through the pressure regulating mask 401 and are located on its inner wall so that the exchanged gas can quickly enter the corresponding gas chamber, preventing gas leakage caused by gas overflow.

[0047] The upper surface of the outer shell 101 is fixedly connected with a fixing belt 601, and the other end of the fixing belt 601 is fixedly connected with a headgear 602. The fixing belt 601 is a magic tape, and the headgear 602 is an elastic binding band.

[0048] The fixing belt 601 fixedly connected to the upper surface of the outer shell 101 is used to fit and fix the outer shell 101 with the patient's face. The headgear 602 fixedly connected to the other end of the fixing belt 601 is used to fix the oxygen inhalation device on the patient's face to prevent the oxygen inhalation device from falling off during oxygen inhalation. In addition, setting the fixing belt 601 as a magic tape allows for quick disassembly of the oxygen inhalation device.

[0049] The flow guide plate 104 is inclined from top to bottom, and the lower flow guide plate 104 is close to the partition plate 107. The partition plate 107 is inclined from bottom to top, and the upper partition plate 107 is close to the sealing plate 106.

[0050] The flow guide plate 104 and the partition plate 107 are respectively set to be inclined so that the condensed water on the surface of the sealing plate 106 can be discharged through the change of the inclined surface during the sliding process.

[0051] Both the face mask 102 and the breathing mask 201 are arc-shaped, and the pressure regulating mask 401 is located inside the opening, while the exhalation chamber 304 and the inhalation chamber 303 are located outside the opening.

[0052] Both the face mask 102 and the breathing mask 201 are arc-shaped so as to be able to fit the patient's face and prevent gas leakage during oxygen inhalation.

[0053] The usage process of an oxygen inhalation device provided by the present invention for preventing backflow of condensed water and nasal pressure injury is as follows:

[0054] When collecting and discharging condensed water, the pull rod 108 can be pulled. During the pulling process of the pull rod 108, the sealing plate 106 can be driven to slide. When the sealing plate 106 slides, on the one hand, the spring 105 can be pulled to stretch. When the spring 105 stretches, it drives the diversion plate 104 to rotate. The rotation of the diversion plate 104 conveys the condensed water inside it to the partition plate 107. Since the partition plate 107 abuts against the sealing plate 106, when the sealing plate 106 slides, the partition plate 107 rotates. When the partition plate 107 rotates to a horizontal state, the condensed water on the partition plate 107 drains out along the partition plate 107.

For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection, an electrical connection or communication with each other; it can be directly connected, or indirectly connected through an intermediate medium. It can be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
