Description

Technical Field

[0001] This utility model relates to the field of hyperbaric oxygen chamber technology, specifically to an oxygen inhalation device for a hyperbaric oxygen chamber. Background Technology

[0002] Hyperbaric oxygen therapy has become a common medical treatment. During the process, patients need to enter the oxygen chamber and wear an oxygen mask. However, most existing oxygen masks are directly placed over the patient's mouth and nose using auxiliary positioning straps. The relatively rigid edges of the oxygen mask directly press against the patient's skin, causing significant pressure on the skin during wear and resulting in extreme discomfort. Furthermore, to ensure a tight seal between the oxygen mask and the patient's mouth and nose, the pressure exerted by the mask on the skin is considerable, often leaving deep indentations that are difficult to heal quickly after treatment.

[0003] Based on this, the present invention designs an oxygen inhalation device for a hyperbaric oxygen chamber to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an oxygen inhalation device for a hyperbaric oxygen chamber, in which a transparent oxygen mask is worn on the patient's mouth and nose through a mouth and nose wrapping layer. The edge of the transparent oxygen mask is sealed to the edge of the patient's mouth and nose through an annular airbag. The flexible fabric mouth and nose wrapping layer and the annular airbag replace the transparent oxygen mask in contact with the patient's skin surface, reducing the patient's discomfort during the wearing process and avoiding leaving pressure marks on the patient's skin surface after oxygen inhalation.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An oxygen inhalation device for a hyperbaric oxygen chamber includes elastic ear loops and a transparent oxygen mask, as well as a positioning frame fixed inside the hyperbaric oxygen chamber. The elastic ear loops are provided in two sets, with a mouth and nose covering layer between the two sets. The mouth and nose covering layer is provided with:

[0007] The soft silicone connector is a ring-shaped piece with openings at both ends. The two openings of the soft silicone connector are respectively connected to the transparent oxygen mask and the mouth and nose wrapping layer. The size of the opening at the end of the soft silicone connector connected to the mouth and nose wrapping layer is larger than the size of the opening at the end connected to the transparent oxygen mask. The soft silicone connector allows oxygen inside the transparent oxygen mask to pass through the mouth and nose wrapping layer and enter the patient's respiratory tract.

[0008] An annular airbag is fixed through the mouth and nose covering layer and surrounds the outside of the soft silicone connector. The left and right sides of the annular airbag are located on the side of the mouth and nose covering layer closer to the transparent oxygen mask, and the top and bottom sides are located on the side of the mouth and nose covering layer away from the transparent oxygen mask. An adjustment component is provided on one side of the annular airbag, which can adjust the size of the annular airbag inflation.

[0009] Preferably, the positioning frame is provided in two sets, and the two sets of positioning frames are fixed to the wall of the hyperbaric oxygen chamber in parallel by bolts. Each positioning frame is provided with a sliding groove, and an internally threaded rod is rotatably installed in the sliding groove. A movable frame is threadedly connected to the internally threaded rod.

[0010] Preferably, an extension crank is slidably connected to the end of the movable frame away from the positioning frame. The lower end of the extension crank extends to the bottom of the movable frame and remains parallel to the positioning frame. A connecting frame is rotatably mounted on the upper end of the extension crank. A side support frame is fixedly mounted on the end of the connecting frame away from the extension crank.

[0011] Preferably, the side support frame is an arc plate that can abut against the outside of the transparent oxygen mask, and the lower end of the side support frame is provided with a snap-fit ​​seat, and the snap-fit ​​seats on both sides can be inserted and snapped into each other.

[0012] Preferably, an oxygen delivery tube is fixedly installed in the middle of the transparent oxygen mask, and the other end of the oxygen delivery tube is connected to an oxygen tank. The elastic ear loops are provided with elastic holes at the ends away from the mouth and nose covering layer.

[0013] Preferably, the adjustment component includes an adjustment valve, which is fixedly installed on the outside of the mouth and nose covering layer. A connecting pipe is fixedly installed between the adjustment valve and the annular airbag. The adjustment valve can be rotated to adjust the size of the orifice at the connection point between the adjustment pipe and the airbag.

[0014] Preferably, a bidirectional motor is fixedly installed at the upper end of the sliding groove, and the output end of the bidirectional motor is fixedly connected to the internal threaded rod. The rotation of the bidirectional motor can drive the movable frame to move up and down.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In this invention, the elastic ear loops are fixed to the patient's ears, thereby positioning the nasal and oral wrapping layer at the patient's mouth and nose. This allows the nasal and oral wrapping layer to support the transparent oxygen mask at the patient's mouth and nose. Oxygen enters from the transparent oxygen mask into the soft silicone connector, and then from the soft silicone connector into the patient's mouth and nose, which is located below the nasal and oral wrapping layer. During oxygen inhalation, the annular airbag on the outer edge of the soft silicone connector ensures that the edge of the transparent oxygen mask is sealed to the edge of the patient's mouth and nose. The flexible fabric nasal and oral wrapping layer and the annular airbag replace the transparent oxygen mask in contact with the patient's skin, reducing patient discomfort during wear and preventing pressure marks from being left on the patient's skin after oxygen inhalation.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-5 This utility model provides a technical solution:

[0027] An oxygen inhalation device for a hyperbaric oxygen chamber includes elastic ear loops 1 and a transparent oxygen mask 14, as well as a positioning frame 7 fixed inside the hyperbaric oxygen chamber. The elastic ear loops 1 are provided in two sets, with a mouth and nose covering layer 3 provided between the two sets. The mouth and nose covering layer 3 is provided with:

[0028] The soft silicone connector 12 is an annular piece with openings at both ends. The two openings of the soft silicone connector 12 are respectively connected to the transparent oxygen mask 14 and the mouth and nose wrapping layer 3. The opening size of the end of the soft silicone connector 12 connected to the mouth and nose wrapping layer 3 is larger than the opening size of the end connected to the transparent oxygen mask 14. The soft silicone connector 12 allows oxygen inside the transparent oxygen mask 14 to pass through the mouth and nose wrapping layer 3 and enter the patient's respiratory tract.

[0029] The annular airbag 11 is fixed to the mouth and nose covering layer 3 and surrounds the outside of the soft silicone connector 12. The left and right sides of the annular airbag 11 are located on the side of the mouth and nose covering layer 3 closer to the transparent oxygen mask 14, and the upper and lower sides are located on the side of the mouth and nose covering layer 3 away from the transparent oxygen mask 14. An adjustment component is provided on one side of the annular airbag 11, which can adjust the size of the annular airbag 11 inflation.

[0030] In this invention, the elastic ear loops 1 are fixed to the patient's ears, thereby positioning the nasal and oral wrapping layer 3 at the patient's mouth and nose. This allows the nasal and oral wrapping layer 3 to support the transparent oxygen mask 14 at the patient's mouth and nose. Oxygen enters from the transparent oxygen mask 14 into the soft silicone connector 12, and then from the soft silicone connector 12 into the patient's mouth and nose below the nasal and oral wrapping layer 3. During oxygen inhalation, the annular airbag 11 located on the outer edge of the soft silicone connector 12 ensures that the edge of the transparent oxygen mask 14 is sealed to the edge of the patient's mouth and nose. The flexible fabric nasal and oral wrapping layer 3 and the annular airbag 11 replace the transparent oxygen mask 14 in contact with the patient's skin, reducing patient discomfort during wear and preventing pressure marks from being left on the patient's skin after oxygen inhalation.

[0031] The positioning frame 7 consists of two sets, both sets of which are bolted parallel to the wall of the hyperbaric oxygen chamber. Each positioning frame 7 has a sliding groove 8, within which an internally threaded rod 9 is rotatably mounted. A movable frame 6 is threaded onto the internally threaded rod 9. After the patient enters the hyperbaric oxygen chamber and puts on the elastic ear loop 1, the patient sits between the positioning frames 7 and adjusts the height of the movable frame 6 so that it is positioned above the patient's shoulders at a suitable height.

[0032] The movable frame 6 has an extension rod 5 slidably connected to the end furthest from the positioning frame 7. The lower end of the extension rod 5 extends below the movable frame 6 and remains parallel to the positioning frame 7. A connecting frame 4 is rotatably mounted on the upper end of the extension rod 5. Side support frames 13 are fixedly mounted on the end of the connecting frame 4 furthest from the extension rod 5. After the height of the movable frame 6 is adjusted to the patient's shoulder, the lower end of the extension rod 5 and the positioning frame 7 clamp the patient's shoulder between them, thereby fixing the position and height of the patient's shoulder. At this time, by rotating the connecting frame 4, the side support frames 13 can be positioned on both sides of the transparent oxygen shaft 14.

[0033] The side support frame 13 is an arc-shaped plate that abuts against the outside of the transparent oxygen mask 14. Each side support frame 13 has a locking seat 15 at its lower end, and the locking seats 15 on both sides can interlock. By locking the two sides of the side support frame 13 together, the transparent oxygen mask 14 is fixed between the side support frames 13, thus supporting the transparent oxygen mask 14 from the bottom. This reduces the burden on the patient when wearing the transparent oxygen mask 14, making it more comfortable for the patient and also making the relative position between the transparent oxygen mask 14 and the patient more stable.

[0034] The transparent oxygen mask 14 has an oxygen delivery tube 10 fixedly installed in the middle, with the other end of the tube connected to an oxygen tank. The elastic ear loops 1, away from the mouth and nose covering 3, each have elastic holes 2. Oxygen enters the transparent oxygen mask 14 through the oxygen delivery tube 10.

[0035] The adjustment component includes an adjustment valve 16, which is fixedly installed on the outside of the mouth and nose covering layer 3. A connecting tube 17 is fixedly installed between the adjustment valve 16 and the annular airbag 11. Rotating the adjustment valve 16 can adjust the size of the orifice at the connection point between the adjustment tube 17 and the airbag. The annular airbag 11 is filled with gas. After the patient wears the device, they can open the adjustment valve 16 according to their own comfort to allow the gas in the annular airbag 11 to overflow through the connecting tube 17 and the adjustment valve 16. The annular airbag fits the patient's facial contours more closely.

[0036] A bidirectional motor is fixedly installed at the upper end of the sliding groove 8. The output end of the bidirectional motor is fixedly connected to the internal threaded rod 9. The rotation of the bidirectional motor can drive the movable frame 6 to move up and down. The forward rotation of the bidirectional motor drives the internal threaded rod 9 to rotate in the forward direction, which causes the movable frame 6 to move upward. The reverse rotation of the bidirectional motor drives the internal threaded rod 9 to rotate in the reverse direction, thereby driving the movable frame 6 to move downward.
