Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an oxygen absorption mask. Background Art

[0002] An oxygen mask is a medical device used to provide high-concentration oxygen to patients, helping them to inhale more oxygen to improve breathing and oxygen supply. An oxygen mask usually consists of a mask and a tube connected to an oxygen supply device. The oxygen mask can cover the patient's mouth and nose to ensure that oxygen enters the respiratory tract directly. In cases of chronic respiratory diseases, heart disease, lung infections, etc., patients need to wear oxygen masks for a long time to ensure that they can continue to get enough oxygen supply, thereby improving breathing and overall health;

[0003] A Chinese patent with publication number "CN219307642U" discloses "an oxygen mask, comprising a mask body for covering the mouth and nose, the mask body being provided with a main duct and a secondary duct for oxygen supply, the main duct and the secondary duct both passing from the outside of the mask body to the inside thereof, the inside of the mask body being provided with a nasal plug for inserting into the nostrils, the secondary duct being communicated with the nasal plug. The present application is easy to wear by providing a secondary duct on the mask body, and is convenient for simultaneous oxygen inhalation by mask and nasal catheter."

[0004] The researchers found that although it can meet the patients' oxygen needs, when the patients perform coughing, cleaning the mouth or other physiological operations that require temporarily removing the mask, the entire mask needs to be removed to perform operations such as coughing, and then put on the mask again, which is very inconvenient and has problems with low practicality and functionality. In addition, when wearing the oxygen mask for a long time, the mask is easy to compress the face and cause discomfort, and during long-term oxygen inhalation, the patient's respiratory tract is easy to become dry, affecting subsequent treatment.

[0018] Compared with the prior art, the utility model provides an oxygen absorption mask with the following beneficial effects:

[0019] 1. By setting a fixing structure, the fixing seat can be quickly fixed or removed under the action of the plug block, so that the patient does not need to remove the entire oxygen mask when performing operations such as coughing up phlegm. By pulling the round rod, the entire fixing seat can be quickly removed under the elastic force of the ejection spring, and then operations such as coughing up phlegm can be performed, which can reduce the interruption time of wearing the mask, improve the patient's comfort and convenience, and facilitate the patient to wear the oxygen mask for a long time, thereby enhancing the practicality and functionality of the oxygen mask;

[0020] 2.

When the fixing seat is removed, the elastic force of the compression spring makes the solid part of the plug plate contact with the through hole, thereby avoiding unnecessary oxygen waste;

[0021] 3. By setting a skin-friendly structure in combination with a fixed structure and a self-sealing structure, the patient can wear the oxygen mask for a long time under the action of the fixed structure without frequent disassembly. By injecting water into the water bag, the water bag can fill the gap between the mask and the patient's head during the mask wearing process, providing a better sealing effect, reducing gas leakage, ensuring that more oxygen enters the patient's respiratory system, and improving the oxygen absorption effect;

[0022] 4. When the patient's facial skin contacts the water bag, the water bag can provide a soft buffer layer between the mask and the patient's head, reducing the irritation and pressure of the mask on the patient's face, helping to improve wearing comfort and reduce the risk of skin abrasion or damage;

[0023] 5. By setting a water bag inside the breathing mask and filling it with water, the humidity of the patient during long-term oxygen inhalation can be increased. Water vapor can reduce the discomfort of the patient's respiratory tract and prevent excessive drying of the mucous membrane, which is especially important for patients with respiratory problems.

[0024] 6. According to different ambient temperatures, water of different temperatures can be injected into the water bag to adjust the temperature inside the mask to meet the needs of patients under different environmental conditions. In a cold environment, injecting warm water can provide extra warmth, while in a hot environment, injecting cool water can lower the temperature inside the mask and provide comfort.

[0025] The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology. The utility model allows patients to cough up phlegm, clean the mouth or other physiological operations that require temporary removal of the mask without removing the entire oxygen mask, and by providing a skin-friendly structure, the comfort of patients when wearing the oxygen mask for a long time can be improved.

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0037] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0038] like Figure 1-9 As shown, an oxygen inhalation mask comprises a mask body 1, four clamping rings 2 are symmetrically fixedly installed on the outside of the mask body 1, a breathing notch 3 is opened at the front of the mask body 1, and a fixing structure 4 is arranged at the front of the breathing notch 3;

[0039] The fixing structure 4 includes two columns 5 and a support plate 6. The two columns 5 are symmetrically fixedly installed on the front part of the mask body 1. The support plate 6 is fixedly installed on the bottom of the column 5. Ejection springs 7 are fixedly installed on both sides of the top of the support plate 6 near the rear. The adjacent sides of the two columns 5 are provided with grooves, and the ejection springs 7 are adaptively matched with the grooves. A cavity 8 is provided inside the column 5 near the top, and an insert block 9 is clamped inside the cavity 8. A round rod 10 is fixedly installed at the middle position outside the insert block 9. A limiting spring 11 is wound around the outside of the round rod 10. A fixing seat 12 is slidably installed between the two columns 5.

[0040] In this embodiment, one end of the insert block 9 is triangular, and a limit block is disposed outside the insert block 9 , and the limit block is adaptively matched with the cavity 8 .

[0041] By inserting the fixing seat 12 between the two columns 5, the square blocks on both sides of the fixing seat 12 will enter the grooves opened in the columns 5. At this time, the square blocks will first squeeze the inclined surface of the plug block 9, so that the plug block 9 compresses the limit spring 11 and shrinks into the interior of the cavity 8, and continues to push the fixing seat 12 until the fixing seat 12 is completely inserted into the groove. At this time, the plug block 9 will be reset under the elastic force of the limit spring 11, so that the plug block 9 will press against the fixing seat 12 to fix the fixing seat 12. During the installation process of the fixing seat 12, the bottom of the fixing seat 12 will continuously compress the ejection spring 7.

[0042] In this embodiment, one end of the limit spring 11 is fixedly mounted on the outside of the insert block 9 , and the other end of the limit spring 11 is fixedly mounted on the inside of the cavity 8 .

[0043] The limit spring 11 will be compressed during the retraction of the insert block 9 to store elastic force. When the fixing seat 12 no longer presses the insert block 9, the insert block 9 will rebound under the elastic force of the limit spring 11 to press the fixing seat 12.

[0044] In this embodiment, the round rod 10 passes through one side of the column 5 , a ball handle is fixedly mounted on one end of the round rod 10 , and a hole is opened in the middle of the fixing seat 12 .

[0045] By pulling the ball handle, when the fixing seat 12 needs to be taken off, the insert block 9 can be driven by the round rod 10 to compress the limit spring 11 and retract. When the insert block 9 is completely retracted into the cavity 8, the fixing seat 12 will be pushed up by the elastic force of the ejection spring 7, so that the operator can easily remove the fixing seat 12 for operations such as coughing up phlegm.

[0046] In this embodiment, a self-enclosed structure 13 is provided inside the fixed seat 12, and the self-enclosed structure 13 includes a through slot 14, an oxygen pipe connection 15 and an insert plate 16. The through slot 14 is opened in the middle position of the top of the fixed seat 12, the oxygen pipe connection 15 is fixedly installed at the front of the fixed seat 12, and the insert plate 16 is slidably installed inside the through slot 14. Blocks 17 are fixedly installed on both sides of the insert plate 16 near the lower middle position, square slots 18 are opened on both sides of the through slot 14, and the square slots 18 are adaptively matched with the block 17. A positioning rod 19 is fixedly installed on the top of the block 17, and a compression spring 20 is wound around the outside of the positioning rod 19. A through hole 21 is opened at the front of the insert plate 16 near the lower middle position.

[0047] When the fixing seat 12 enters between the two pillars 5, the plug plate 16 will first contact the support plate 6. At this time, since the support plate 6 is fixed, the plug plate 16 will be resisted, so that the blocks 17 on both sides of the plug plate 16 slide inside the square groove 18, and then the compression spring 20 will be compressed. When the fixing seat 12 is fixed by the fixing structure 4, the through hole 21 opened on the plug plate 16 will coincide with the holes opened on the oxygen connecting pipe 15 and the fixing seat 12, so as to facilitate the delivery of oxygen into the interior of the mask body 1.

[0048] In this embodiment, one end of the compression spring 20 is fixedly mounted on the top of the stopper 17 , the other end of the compression spring 20 is fixedly mounted on the top of the square groove 18 , and the positioning rod 19 passes through the top of the fixing seat 12 .

[0049] When the round rod 10 is pulled so that the fixing seat 12 is pushed out by the ejection spring 7, the stopper 17 is squeezed to slide inside the square groove 18 under the elastic force of the compression spring 20, so that the plug plate 16 slides to the bottom of the fixing seat 12, so that the solid part of the plug plate 16 contacts the through hole 21, so that when the fixing seat 12 is removed, the oxygen supply channel is automatically closed to save oxygen.

[0050] In this embodiment, the diameter of the through hole 21 is consistent with that of the oxygen connecting pipe 15 , and the through hole 21 is adaptively matched with the fixing seat 12 .

[0051] The through hole 21 is adaptively matched with the fixing seat 12 , which can facilitate the delivery of oxygen into the interior of the mask body 1 .

[0052] In this embodiment, square blocks are provided on both sides of the fixing seat 12 near the rear, and the square blocks are adaptively matched with the grooves provided on the adjacent sides of the two columns 5 .

[0053] In this embodiment, a skin-friendly structure 22 is provided at the rear of the mask body 1, and the skin-friendly structure 22 includes a water bag 23. The water bag 23 is fixedly installed inside the mask body 1 near the rear position, and a water filling port 24 is installed at the top of the water bag 23, and a water outlet 25 is installed at the bottom of the water bag 23.

[0054] When the oxygen mask is worn for a long time, it will exert pressure on the facial skin. By injecting water into the water bag 23, the water bag 23 can be expanded to fit the patient's face, thereby reducing the stimulation and pressure of the mask on the patient's face, helping to improve wearing comfort and reduce the risk of skin abrasion.

[0055] In this embodiment, the water inlet 24 and the water outlet 25 both penetrate the mask body 1 , and air holes are provided on the outside of the mask body 1 near both sides.

[0056] The water inside the water bag 23 can be easily supplemented or replaced through the water inlet 24 and the water outlet 25.

[0057] It should be noted that the utility model is an oxygen absorption mask. When in use, water is first filled into the water bag 23 through the water filling port 24. After the water filling is completed, the water filling port 24 and the water outlet 25 are closed, and a connecting rope is set on the clamp ring 2 outside the mask body 1. The oxygen absorption mask is worn on the patient's face through the connecting rope, so that the water bag 23 is in contact with the patient's facial skin;

[0058] Insert the fixing seat 12 between the two pillars 5, and the square blocks on both sides of the fixing seat 12 will first enter the grooves opened in the pillars 5. At this time, the square blocks will first squeeze the inclined surface of the plug block 9, so that the plug block 9 compresses the limit spring 11 and shrinks into the interior of the cavity 8, and continue to push the fixing seat 12 until the fixing seat 12 is completely inserted into the groove. At this time, the plug block 9 will be reset under the elastic force of the limit spring 11, so that the bottom of the plug block 9 is against the top of the fixing seat 12 to fix the fixing seat 12. During the installation of the fixing seat 12, the bottom of the fixing seat 12 will continuously compress the ejection spring 7, and then the oxygen cylinder can be connected to the outside of the oxygen pipe 15 for oxygen supply operation;

[0059] When the fixing seat 12 enters between the two uprights 5, the plug plate 16 in the self-sealing structure 13 will first contact the support plate 6. At this time, since the support plate 6 is fixed, the plug plate 16 will be resisted, so that the stoppers 17 on both sides of the plug plate 16 slide inside the square groove 18, and then the compression spring 20 will be compressed. When the fixing seat 12 is fixed by the fixing structure 4, the through hole 21 opened on the plug plate 16 will coincide with the hole positions opened on the oxygen pipe 15 and the fixing seat 12, so that oxygen can be transported into the interior of the mask body 1 to complete the oxygen supply operation for the patient;

[0060] When the patient needs to perform operations such as expectoration, there is no need to take off the entire oxygen mask. The patient only needs to pull the round rod 10 with both hands, so that the insert block 9 is driven by the round rod 10 to compress the limit spring 11 and retract into the cavity 8. When the insert block 9 is completely retracted into the cavity 8, the fixing seat 12 will be pushed up by the elastic force of the ejection spring 7, so that the operator can take off the fixing seat 12 to perform operations such as expectoration.

[0061] When the fixing seat 12 is removed, the compression spring 20 will be reset. Under the elastic force of the compression spring 20, the stopper 17 will slide inside the square groove 18, so that the plug plate 16 slides toward the bottom of the fixing seat 12, so that the solid part of the plug plate 16 contacts the through hole 21, so that when the fixing seat 12 is removed, the oxygen supply channel is automatically closed to save oxygen;

[0062] Water of different temperatures can be injected into the water bag 23 according to different ambient temperature conditions, thereby improving the patient's oxygen mask wearing experience.

[0063] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
