Description

Technical Field

[0001] This utility model belongs to the field of medical equipment technology and relates to an oxygen mask, specifically an oxygen mask for use in a hyperbaric oxygen chamber. Background Technology

[0002] A hyperbaric oxygen chamber is a specialized medical device for administering hyperbaric oxygen therapy. It increases environmental pressure, allowing more oxygen to dissolve in the blood, thereby treating or assisting in the treatment of various hypoxic diseases. The use of a hyperbaric oxygen chamber typically requires the use of an oxygen mask to ensure that the patient can safely and effectively inhale oxygen in a high-pressure environment.

[0003] Currently, conventional oxygen masks used at normal pressure are generally divided into two types due to different exhaust methods: one type has a ventilation hole on the mask body itself, through which the patient's exhaust gas is discharged; the other type is a closed mask body, but with an additional exhaust pipe installed next to the inlet pipe, through which the patient's exhaust gas is discharged from the mask body.

[0004] The use of oxygen masks in hyperbaric oxygen chambers differs from that of conventional oxygen masks used on oxygen delivery lines at normal pressure. When using a conventional oxygen mask, oxygen automatically enters the mask for the patient to breathe due to the pressure inside the oxygen cylinder. However, when using an oxygen mask in a hyperbaric oxygen chamber, oxygen does not automatically enter the mask; instead, the patient must inhale the oxygen stored in the storage chamber into the mask for use.

[0005] However, in practical applications, there are currently no oxygen masks specifically designed for hyperbaric oxygen chambers. Instead, conventional oxygen masks with closed-type covers are directly applied to hyperbaric oxygen chambers. Because the inlet and outlet of such oxygen masks are usually positioned relatively low and are always open, they cannot be adjusted to open or close according to the patient's breathing. This leads to situations where, when conventional oxygen masks are used in hyperbaric oxygen chambers, the patient's oxygen intake efficiency is low, and oxygen mixes with exhaust gas and is inhaled by the patient, which is detrimental to treatment. Utility Model Content

[0006] To address the aforementioned shortcomings in the existing technology, this utility model aims to provide a hyperbaric oxygen mask to improve the patient's oxygen intake efficiency and prevent the mixing of oxygen and exhaust gas during inhalation.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A hyperbaric oxygen chamber oxygen mask includes a mask body, a breathing unit fixed to the mask body, and a fixing unit fixed to the mask body for fixing the mask body to a human face; wherein the shape of the mask body is adapted to the shape of the human face, and the mask body is provided with a ventilation platform corresponding to the human nostrils for connecting the breathing unit near the human nose; the breathing unit includes a mask connector communicating with the inside of the mask, an inlet pipe and an exhaust pipe fixedly connected to the mask connector, a one-way inlet valve fixed between the mask connector and the inlet pipe, and a one-way exhaust valve fixed between the mask connector and the exhaust pipe.

[0009] As a limitation of this utility model, the top edge of the cover that contacts the face is a groove adapted to the shape of the bridge of the nose.

[0010] As a further limitation of this utility model, a silicone gasket is provided at the edge of the cover that contacts the face.

[0011] As another limitation of this utility model, the one-way air intake valve includes a first valve body, a first venting baffle fixed inside the first valve body, and a first valve flap fixed below the first venting baffle. The first valve body is an internally penetrating frustum, and the area of ​​the first valve flap is the same as the area of ​​the lower surface of the first venting baffle. The structure of the one-way air outlet valve is the same as that of the one-way air intake valve, including a second valve body, a second venting baffle, and a second valve flap. The lower bottom surface of the one-way air intake valve is connected to the mask connector, and the upper bottom surface of the one-way air outlet valve is connected to the mask connector.

[0012] As a further limitation of this utility model, the fixing unit includes fixing straps with both ends fixed to the outer surface of the cover and drawstring buckles assembled on the fixing straps.

[0013] As a further limitation of this utility model, at least two fixing straps are provided, and the width of the fixing straps is 5-10mm.

[0014] By adopting the above-mentioned technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows:

[0015] (1) This utility model designs a novel oxygen mask for hyperbaric oxygen chambers, which can improve the oxygen intake efficiency of patients in hyperbaric oxygen chambers and prevent exhaled waste gas from being re-inhaled by patients. Specifically, this utility model shortens the distance between the air inlet and the nostrils by setting an air vent that corresponds to the position of the human nostrils, thereby improving the oxygen intake efficiency of patients. When patients exhale, waste gas can also be discharged in time, preventing waste gas from remaining in the mask and being re-inhaled by patients.

[0016] In addition, a one-way inlet valve and a one-way exhaust valve are respectively installed between the mask connector and the inlet and exhaust pipes, which can keep the exhaust pipe blocked when the patient inhales and the inlet pipe blocked when exhaling, preventing the patient from mixing oxygen and exhaust gas inhalation.

[0017] (2) In this utility model, the edge of the mask that contacts the face is provided with a groove for placing the bridge of the nose, and the edge of the mask is provided with a silicone gasket, which can enhance the sealing between the oxygen mask and the face while ensuring wearing comfort, and improve the oxygen inhalation effect of the patient.

[0018] (3) The fixing strap used to fix the oxygen mask to the face in this utility model is equipped with a drawstring buckle. The tightness of the oxygen mask can be quickly adjusted by the drawstring buckle, which greatly improves the wearing efficiency.

[0019] (4) The width of the fixing strap in this utility model is 5-10mm, which can effectively reduce the pressure on the contact point between the human body and the strap and improve the wearing comfort. Attached Figure Description

[0030] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0031] This embodiment discloses an oxygen mask for a hyperbaric oxygen chamber, such as... Figure 1 As shown, it includes a mask 1, a breathing unit, and a fixing unit.

[0032] like Figures 1 to 2 As shown, the cover 1 is a sealed plastic shell. The shape of the cover 1 is adapted to the human face. The part of the cover 1 near the human nose is provided with a ventilation platform 11. The position of the ventilation platform 11 corresponds to the human nostrils and is connected to the breathing unit. The edge of the cover 1 that contacts the human face is provided with a groove 12 for placing the bridge of the nose. When wearing it, the bridge of the nose will be placed in the groove 12 and will not push the cover 1 up. In addition, a silicone gasket 13 is provided on the edge of the cover 1 that contacts the human face. When in use, it can fit the cover 1 tightly against the human face in conjunction with the aforementioned groove 12.

[0033] The breathing unit includes a mask connector 2, an inlet pipe 5, an outlet pipe 6, a one-way inlet valve 3, and a one-way outlet valve 4, such as Figure 1 As shown, the mask connector 2 is a plastic tee. One end of the tee is connected to the ventilation platform 11 on the mask body 1. The other two ends are respectively fixed with a one-way air intake valve 3 and a one-way air exhaust valve 4. The end of the one-way air intake valve 3 away from the mask connector 2 is fixed with an air intake pipe 5, and the end of the one-way air exhaust valve 4 away from the mask connector 2 is fixed with an exhaust pipe 6.

[0034] It should be added here that, such as Figure 3 As shown, the one-way air intake valve 3 includes a first valve body 31, a first ventilator baffle 32 fixed inside the first valve body 31, and a first valve flap 33 fixed at the lower part of the ventilator baffle. The first valve body 31 is an internally penetrating frustum, and the lower bottom surface of the frustum is connected to the mask connector 2. The first ventilator baffle 32 consists of a fixed cylinder located at the centroid of the first valve body 31 and six reinforcing ribs evenly distributed around the fixed cylinder and connected at both ends to the fixed cylinder and the inner surface of the first valve body 31, respectively. The first valve flap 33 is a rubber soft membrane, which is fixed to the side of the first ventilator baffle 32 near the lower bottom surface of the first valve body 31 by the fixed cylinder of the first ventilator baffle 32. The area of ​​the first valve flap 33 is the same as the cross-sectional area of ​​the internal through hole of the first valve body 31 cut off by the lower surface of the first ventilator baffle 32.

[0035] The one-way exhaust valve 4 includes a second valve body 41, a second ventilation baffle 42, and a second valve 43. The one-way exhaust valve 4 has the same structure as the one-way intake valve 3, the difference being that the second valve body 41 is connected to the mask connector 2 via its upper bottom surface. When the patient inhales, as... Figures 4 to 5As shown, the first valve 33 tilts upwards around its edges under the patient's suction, allowing oxygen to flow through the first ventilator 32 into the hood 1. At the same time, the second valve 43 adheres tightly to the second ventilator 42 under the action of suction, preventing exhaust gas in the exhaust pipe 6 from flowing into the hood 1. Similarly, when the patient exhales, the second valve 43 tilts upwards under the action of the exhaled airflow, allowing the exhaled exhaust gas to be discharged through the second ventilator 42. At the same time, the first valve 33 adheres tightly to the first ventilator 32 under the action of the exhaled airflow, preventing the exhaled exhaust gas from entering the intake pipe 5.

[0036] The fixing unit includes a fixing strap 7 and a drawstring buckle 8, such as Figure 1 As shown, the two ends of the fixing strap 7 are respectively fixed to the outer surface of the cover 1 near the left and right edges. The width of the fixing strap 7 is 5-10mm. In this embodiment, the fixing strap 7 is an elastic band with a width of 5mm. There are two fixing straps 7, which are respectively set on the upper half and the lower half of the cover 1. The drawstring buckle 8 is set in the middle of the fixing strap 7.

[0037] When using this embodiment, first fasten the cover 1 onto the human face, then put the fixing strap 7 on the human head to initially fix the cover 1. Then adjust the position of the drawstring buckle 8 on the fixing strap 7 to adjust the tightness of the cover 1 fastened onto the human face. After the adjustment is completed, connect the air inlet pipe 5 and the exhaust pipe 6 to the oxygen chamber and the exhaust chamber respectively, and it can be used.

[0038] It should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
