Description

Technical Field

[0001] The utility model relates to the technical field of critical care, in particular to an oxygen mask with adjustable tightness. Background Technique

[0002] An oxygen mask is a device for assisting patients in routine oxygen inhalation. It is widely used in the field of critical care. Compared with nasal catheter oxygen inhalation, the oxygen inhalation efficiency of the oxygen mask is high. At the same time, it can adjust the oxygen concentration provided to the patient as needed, thereby partially or completely avoiding the patient's rebreathing. However, the oxygen mask is a fixed device and is not easy to expectorate phlegm and eat during use. Therefore, it is mainly used for first aid or patients who require a higher oxygen concentration. However, since the device fits closely with the patient's face during operation and the self-regulation ability of critical patients is poor, the skin of the patient at the covered part of the device is prone to hypothermia, increasing the negative impact during the operation of the device, thus affecting the practicability of the device.

[0003] Based on this, the utility model designs an oxygen mask with adjustable tightness to solve the above problems. Content of the Utility Model

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-3, the present utility model provides a technical solution: an oxygen mask with adjustable tightness, including a carrying mask 1, an oxygen supply elbow 2 is connected to the front of the carrying mask 1, and two groups of constant temperature covers 3 are arranged on the outer surface of the carrying mask 1. Through the constant temperature cover 3, an external temperature adjustment pipeline injects a temperature adjustment medium into the constant temperature cover 3 through a diversion pipe 5. The temperature adjustment medium in the constant temperature cover 3 is output through a series pipe 4 under the action of pressure. During this process, the temperature adjustment medium exchanges heat with the facial skin of the patient through the carrying mask 1, thereby ensuring the temperature of the facial skin of the patient, reducing the probability of skin hypothermia of the patient in the covered part of the device, reducing the negative impact during the operation of the device, and thus enhancing the practicability of the device. The top and bottom of each group of constant temperature covers 3 are respectively connected with a series pipe 4 and a diversion pipe 5, and two groups of deflection seats 6 are arranged on the outer side surface of each group of constant temperature covers 3. A binding strap 7 is slidably inserted between the inner walls of the two opposite deflection seats 6. Through the binding strap 7, when the device needs to be replaced, first separate the magic tape male buckle 8 from the magic tape female buckle 9, and then drive the binding strap 7 to move along the inner wall of the deflection seat 6. After the binding strap 7 is separated from the deflection seat 6, replace the remaining part. During this process, the patient's head does not need to move. At the same time, by displacing the magic tape male buckle 8 relative to the magic tape female buckle 9, the pressure between the binding strap 7 and the carrying mask 1 is adjusted, reducing the impact on the patient during the replacement of the device and improving the convenience of adjusting the tightness of the device. Two groups of magic tape male buckles 8 and magic tape female buckles 9 are arranged on the outer surface of each group of binding straps 7. The back of each group of magic tape male buckles 8 is adhesively fixed to the front of the corresponding magic tape female buckle 9. A flexible sleeve 10 is slidably sleeved on the outer surface of each group of binding straps 7. A conforming airbag 11 is arranged on the back of the carrying mask 1. Through the flexible sleeve 10 and the conforming airbag 11, the flexible sleeve 10 reduces its pressure on the premise of ensuring the tightening stress between the binding strap 7 and the patient's head through its own elastic deformation. Then, place the carrying mask 1 on the patient's face. During this process, the carrying mask 1 drives the conforming airbag 11 to fit with the patient's face. The conforming airbag 11 reduces its pressure on the premise of ensuring the airtightness between the carrying mask and the patient's face through its own elastic deformation, improving the comfort of the patient wearing the device, and thus enhancing the applicability of the device.

[0024] In the present utility model, in order to reduce the number of external pipelines connected to the device, a merging hose 12 for connecting them in series is connected between the connecting ends of the two groups of series pipes 4. Thus, the two groups of constant temperature covers 3 use a group of external temperature adjustment pipelines. The diameter of each group of series pipes 4 is smaller than the diameter of the merging hose 12, thereby reducing the number of external pipelines connected to the device.

[0025] In the present utility model, in order to reduce the speed of bacteria growth inside the constant temperature cover 3, sealing end caps 13 for sealing the device during standby are screwed at the connection ends of each group of diversion tubes 5. Multiple groups of friction-increasing ridges are provided on the outer surface of each group of sealing end caps 13, thereby reducing the speed of bacteria growth inside the constant temperature cover 3.

[0026] In the present utility model, in order to improve the comfort of patients using the device, multiple groups of ventilation annular grooves 14 for air exchange are provided on the outer surface of each group of flexible sleeves 10, so as to discharge the moisture on the skin of the patients in contact with the flexible sleeves 10. The depth of each group of ventilation annular grooves 14 is one-half of the wall thickness of the corresponding flexible sleeve 10, thereby improving the comfort of patients using the device.

[0027] In the present utility model, in order to improve the convenience during the disassembly and assembly of the device, anti-slip pads 15 for increasing the friction between the device and the hands of personnel are provided on the outer side surfaces of each group of constant temperature covers 3. Multiple groups of anti-slip grooves for enhancing the friction coefficient are provided on the outer side surfaces of each group of anti-slip pads 15, thereby improving the convenience during the disassembly and assembly of the device.

[0028] In the present utility model, in order to improve the convenience of observing the patient's face covered by the device, the transparency of each group of constant temperature covers 3 and the bearing face masks 1 is set to be greater than 90%. Thus, doctors can observe the patient's face through the constant temperature covers 3 and the bearing face masks 1. The materials of each group of constant temperature covers 3 and the bearing face masks 1 are medical-grade polypropylene, thereby improving the convenience of observing the patient's face covered by the device.

[0029] In use, first wind the binding strap 7 around the patient's head. During this process, the binding strap 7 drives the flexible sleeve 10 to fit with the skin of the patient's head. The flexible sleeve 10 reduces its pressure through its own elastic deformation while ensuring the binding stress between the binding strap 7 and the patient's head. Then, place the carrying mask 1 on the patient's face. During this process, the carrying mask 1 drives the conformable airbag 11 to fit with the patient's face. The conformable airbag 11 reduces its pressure through its own elastic deformation while ensuring the airtightness between the carrying mask and the patient's face. Then, insert the binding strap 7 into the inside of the deflection seat 6, and then drive the binding strap 7 to move along the inner wall of the deflection seat 6. After the binding strap 7 is tightened, fix itself through the hook-and-loop fastener male part 8 and the hook-and-loop fastener female part 9. Then, connect the oxygen supply elbow 2 with the external pipeline. The oxygen in the external pipeline enters the carrying mask 1 through the oxygen supply elbow 2 for the patient to inhale. At the same time, the external temperature control pipeline injects the temperature control medium into the constant temperature cover 3 through the diversion pipe 5. The temperature control medium in the constant temperature cover 3 is output through the series pipe 4 under the action of pressure. During this process, the temperature control medium exchanges heat with the patient's facial skin through the carrying mask 1, thereby ensuring the temperature of the patient's facial skin. When the device needs to be replaced, first separate the hook-and-loop fastener male part 8 from the hook-and-loop fastener female part 9, and then drive the binding strap 7 to move along the inner wall of the deflection seat 6. After the binding strap 7 is separated from the deflection seat 6, replace the remaining part. During this process, the patient's head does not need to be displaced.

[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
