Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more particularly to a hyperbaric oxygen chamber oxygen breathing mask for patients with indwelling gastric tubes. Background Art

[0002] The hyperbaric oxygen chamber oxygen mask for patients with indwelling gastric tubes is composed of a mask body, an oxygen tube connector, a gastric tube connector and an extrusion cap. The device has a unique gastric tube connector design that can fix the gastric tube and prevent air leakage, thereby meeting the special needs of patients during hyperbaric oxygen therapy.

[0003] In the prior art, the Chinese invention patent with publication number CN 220360606 U discloses a hyperbaric oxygen chamber oxygen mask for patients with indwelling gastric tubes. The key points of the technical solution are that the gastric tube is fixed by providing a gastric tube joint, an annular airbag and a squeeze cap, thereby enhancing the airtightness of the oxygen mask when using the gastric tube and avoiding air leakage between the gastric tube and the oxygen mask. Moreover, the annular airbag is deformed by rotating the squeeze cap to fix or loosen the gastric tube, without the need to inflate or deflate the annular airbag, and the operation is simple.

[0004] Although the above-mentioned prior art can realize the ability to inject materials of different shapes according to different usage requirements, in actual use, patients with indwelling gastric tubes often need to wear oxygen masks for a long time to inhale oxygen. During the process of gastric tube insertion, the throat and nasal mucosa may be irritated, resulting in increased glandular secretions on the mucosa and sputum in the throat. In addition, since the patient's immunity is poor during the period of gastric tube insertion, he may be infected by pathogens such as viruses and bacteria, causing upper respiratory tract infection, resulting in increased secretions in the airway, accompanied by symptoms such as coughing and runny nose. However, conventional oxygen masks do not have a hole for the suction tube to pass through, so the mask can only be opened to suction the sputum and oxygen inhalation is suspended, which has an adverse effect on the patient's recovery. Summary of the invention

[0015] Compared with the prior art, the technical solution provided by the present invention has at least the following beneficial effects:

[0016] In the above scheme, by setting the cooperation between the sputum suction mechanism and the sputum removal mechanism, first, when the sputum suction operation is performed on the patient with a gastric tube, the sputum removal mechanism is operated to generate suction on the inner side of the second rubber hose, so that negative pressure is generated inside the corrugated hose. Due to the pressure difference inside the corrugated hose, the sputum in the nasal cavity can be sucked into the inner side of the corrugated hose through the Z-shaped through hole, and the corrugated hose is reciprocatedly expanded and contracted during the reciprocating suction process of the sputum removal mechanism, which can further enhance the suction force and make the negative pressure fluctuation inside the corrugated hose more obvious. The sputum suction effect in the nasal cavity is better. Since the Z-shaped through hole is designed in a Z shape to increase the tortuosity of the channel, the sputum will not directly impact a certain position when being sucked in, but will flow in a dispersed manner. At the same time, the dynamic expansion and contraction of the corrugated groove shape can continuously change the flow cross-section, prevent the sputum from accumulating at a certain point and causing blockage, and can guide the sputum or foreign matter to move in a specific direction, avoiding the foreign matter from staying in the pipeline and forming a blockage, so that during the negative pressure suction process, the airflow vortex can be reduced, and the efficiency of the fluid (sputum, foreign matter) being quickly sucked out can be improved, thereby improving the overall practicality of the device;

[0017] Through the cooperation of parts such as the fluid exchange pot, when the sputum is sucked into the inner side of the corrugated hose, it slides downward along the inner tube wall of the corrugated hose under the action of gravity and suction. When the sputum moves to the fluid exchange port at the bottom of the second rubber hose, the sputum will fall into the liquid collecting box along the tube wall of the fluid exchange port, and finally can move along the discharge port of the fluid exchange pot to the bottom of the fluid exchange pot for collection, thereby preventing all the sputum from accumulating on the inner side of the second rubber hose, causing blockage of the second rubber hose and affecting the operation of the device. When the sputum accumulates to two-thirds of the fluid exchange pot, the fluid exchange pot can be removed by rotating the fluid exchange pot to clear the sputum inside, thereby realizing the removal of the sputum, so that the staff does not have to wait until the sputum fills the second rubber hose, and then needs to remove the second rubber hose to clear the sputum on the inner side of the second rubber hose, thereby reducing the labor intensity of the staff and improving the overall practicality of the device.

[0018] By setting up the coordination of parts such as the arc-shaped piston block, when the driving plate continues to rotate along the limiting slide groove under the rotation of the annular turning handle, when the driving plate rotates to the bottom of the arched track, the driving plate is continuously raised under the action of the arched track, and when the first arc-shaped piston plate is attached to the inner side of the second arc-shaped piston plate, the limiting clamping plate is in the inner groove of the first arc-shaped piston plate and is parallel to one side of the first arc-shaped piston plate. When the arc-shaped piston block is separated from the first arc-shaped piston plate during the rising process, the second arc-shaped piston plate is Under the action of the limiting clamping plate, it presses against the outer wall of the arc-shaped piston block. At this time, the second compression spring is no longer subjected to external force, and pushes the first arc-shaped piston plate to reset, thereby opening the first circular hole and the second circular hole, so that the negative pressure inside the second rubber hose can be automatically discharged through the rectangular through hole, thereby avoiding pushing air into the nasal cavity during the resetting process of the first arc-shaped piston plate and the second arc-shaped piston plate, irritating the nasal cavity of the gastric tube patient and causing discomfort to the patient, so that the device can suction the patient's nasal cavity in a gentle suction manner, thereby improving the overall practicality of the device.

[0019] By setting the cooperation of parts such as the arch track, when the arc piston block is first separated from the first arc piston plate during the continued rotation process, and then separated from the second arc piston plate during the continued upward movement along the arch track, the arc piston block will continue to move upward along the arch track until it shrinks to the inner side of the sealing ring. When the arc piston block passes over the reset plate, the arc piston block moves from the topmost point to the lowest point of the arch track during the continued rotation, so that after the arc piston block is reset to the initial position, it contacts with another group of first arc piston plate and second arc piston plate and repeats the above operation to continue to form suction. Through the cooperation of the above multiple parts, the inside of the second rubber hose is subjected to unidirectional suction during the continuous circular rotation of the annular turning handle, thereby improving the suction efficiency of sputum in the nasal cavity and improving the overall practicality of the device.

[0040] like Figures 1 to 11As shown, an embodiment of the present invention provides an oxygen mask for a hyperbaric oxygen chamber for a patient with an indwelling gastric tube, comprising: an oxygen mask 1, wherein a sputum suction mechanism 3 is arranged on the inner side of the oxygen mask 1 for suctioning sputum in the nasal cavity of the patient with the gastric tube, wherein the sputum suction mechanism 3 comprises a second rubber hose 303 fixedly connected to the inner side of the oxygen mask 1, wherein one end of the second rubber hose 303 is fixedly connected to a corrugated hose 302, wherein one end of the corrugated hose 302 is fixedly connected to a first rubber hose 301; a gastric tube 2, wherein the gastric tube 2 is arranged on the inner side of the second rubber hose 303 and passes through the inner side of the first rubber hose 301, and a sealing rubber for sealing the gastric tube 2 is arranged at a contact portion between the inner side of the first rubber hose 301 and the gastric tube 2; and a sputum removal mechanism 4, wherein the sputum removal mechanism 4 is arranged on one side of the sleeve 310 for suctioning the second rubber hose 303 in an uninterrupted reciprocating manner. The sputum suction mechanism 3 further comprises a sleeve 310 fixedly connected to one side of the second rubber hose 303, a stomach tube joint 305 fixedly connected to one side of the sleeve 310, a ring-shaped airbag 306 fixedly connected to the inner side of the stomach tube joint 305, an extrusion cap 304 threadedly connected to the inner side of the stomach tube joint 305, and the ring-shaped airbag 306 is tightly attached to the outer wall of the stomach tube 2, a fluid replacement component is arranged at the bottom of the second rubber hose 303, the fluid replacement component comprises a fluid collection box 308 fixedly connected to the fluid replacement port of the second rubber hose 303, a fluid replacement pot 309 threadedly connected to the bottom of the fluid collection box 308, a corrugated groove is arranged on the inner side of the second rubber hose 303, a plurality of Z-shaped through holes 307 penetrating to the outside are arranged inside the second rubber hose 303, and the Z-shaped through holes 307 are arranged in a Z shape.

[0041] First, when suctioning is performed on a patient with a gastric tube, the expectorant mechanism 4 is operated to generate suction on the inner side of the second rubber hose 303, thereby generating negative pressure inside the corrugated hose 302. Due to the pressure difference inside the corrugated hose 302, the sputum in the nasal cavity can be sucked into the inner side of the corrugated hose 302 through the Z-shaped through hole 307. In addition, during the reciprocating suction process of the expectorant mechanism 4, the corrugated hose 302 reciprocates to expand and contract, which can further enhance the suction force and make the negative pressure fluctuation inside the corrugated hose 302 more obvious, thereby enhancing the nasal cavity. The sputum in the cavity can be sucked out more effectively. Since the Z-shaped through hole 307 is designed in a Z-shape to increase the tortuosity of the channel, the sputum will not directly impact a certain position when being sucked in, but will flow in a dispersed manner. At the same time, the dynamic expansion and contraction of the corrugated groove shape can continuously change the flow cross-section to prevent the sputum from accumulating at a certain point and causing blockage. The sputum or foreign matter can be guided to move in a specific direction to prevent the foreign matter from staying in the pipeline and forming a blockage. In the process of negative pressure suction, the airflow vortex can be reduced, and the efficiency of the fluid (sputum, foreign matter) being quickly sucked out can be improved, thereby improving the overall practicality of the device.

[0042] The fluid exchange pot 309 is made of transparent material. When the sputum is sucked into the inner side of the corrugated hose 302, it slides downward along the inner tube wall of the corrugated hose 302 under the action of gravity and suction. When the sputum moves to the fluid exchange port at the bottom of the second rubber hose 303, the sputum will fall into the fluid collection box 308 along the tube wall of the fluid exchange port, and finally can move along the drainage port of the fluid exchange pot 309 to the bottom of the fluid exchange pot 309 for collection, thereby preventing the sputum from accumulating completely on the inner side of the second rubber hose 303 and protecting the first The second rubber hose 303 causes blockage, affecting the operation of the device. When sputum accumulates to two-thirds of the fluid exchange pot 309, the fluid exchange pot 309 can be rotated to remove the fluid exchange pot 309 and clear the sputum inside, thereby achieving the removal of the sputum. The staff does not have to wait until the sputum fills the second rubber hose 303 and then remove the second rubber hose 303 to clear the sputum inside the second rubber hose 303, thereby reducing the labor intensity of the staff and improving the overall practicality of the device.

[0043] When the staff inserts the gastric tube 2 into the sleeve 310 and passes it through the first rubber hose 301 into the body of the gastric tube patient, if the gastric tube 2 needs to be fixed, the staff can rotate the squeezing cap 304 and screw it into the inner side of the gastric tube connector 305 to squeeze the annular airbag 306 so that the annular airbag 306 presses the gastric tube 2 and improves the sealing of the sleeve 310, thereby increasing the adaptability and flexibility of the device, allowing the staff to adjust and optimize according to the specific situation and needs of the patient, and also making the fixing method simpler. The staff can easily complete operations such as inflation, deflation and adjustment, which is also convenient for patients and their families to carry out daily care and observation.

A second compression spring 417 is installed between the second arc-shaped piston plate 416 and the first arc-shaped piston plate 415. A first circular hole 423 is provided on one side of the first arc-shaped piston plate 415 and passes through to the other side. The first circular hole 423 and the second circular hole 424 are staggered. A connecting hole 425 is provided on the inner side of the first circular hole 423 and is located on the front side of the first arc-shaped piston plate 415 and passes through to the bottom. A rectangular through hole 402 is provided on the inner side of the sleeve 310 and passes through to the outside, and the rectangular through hole 402 is located between the bottom plate 426 and the fixing ring 405. A fixing plate 419 is fixedly connected to the top of the bottom plate 426, and the fixing plate 419 is initially attached to the front end of the first arc-shaped piston plate 415.

[0045] The power shifter includes a rotating ring 404 rotatably connected to the inner side of the sleeve 310, one end of the rotating ring 404 is fixedly connected to a connecting column 403, one end of the connecting column 403 is fixedly connected to an annular turning handle 401, the other end of the rotating ring 404 is fixedly connected to a sliding column 408, the outer wall of the sliding column 408 is slidably connected to a driving plate 409, the inner side of the driving plate 409 is slidably connected to a limiting column 410, one end of the limiting column 410 penetrates through the inner side of the driving plate 409 and is fixedly connected to an arc piston block 407, the other end of the limiting column 410 penetrates through the outer side of the driving plate 409, a first compression spring 411 is installed between the limiting column 410 and the driving plate 409, a groove with a diameter larger than that of the arc piston block 407 is opened at the top of the first arc piston plate 415, a limiting clamping plate 420 is fixedly connected to the inner side of the second arc piston plate 416, and the limiting clamping plate 420 is located on one side of the groove.

[0046] like Figure 8 As shown, the power shifter also includes three groups of arched tracks 412 opened on the inner side of the sleeve 310, and the three groups of arched tracks 412 are connected by limiting slide grooves 418. A fixed seat 413 is fixedly connected to one side of the driving plate 409, and a rotating wheel 414 is rotatably connected to the inner side of the fixed seat 413, and the fixed seat 413 is slidably connected to the inner side of the arched track 412.

[0047] When a patient with a gastric tube needs to remove fluid and suction phlegm, the staff can rotate the annular handle 401 to drive the rotating ring 404 to rotate, thereby driving the sliding column 408 to rotate, so that the driving plate 409 drives the arc piston block 407 to move. When the arc piston block 407 contacts the first arc piston plate 415, the first arc piston plate 415 is pushed to move toward the second arc piston plate 416. When the first arc piston plate 415 is attached to the outer wall of the second arc piston plate 416, the first circular hole 423 and the second circular hole 424 are blocked, so that the space between the reset plate 421 and the second arc piston plate 416 forms a closed environment, so that the arc piston block 407 continues to rotate, and during the process of pushing the first arc piston plate 415 toward the second arc piston plate 416 and rotating toward the reset plate 421, the second rubber hose 303 can be sucked, so that the sputum inside the nasal cavity is sucked into the second rubber hose 303.

[0048] When the driving plate 409 continues to rotate along the limiting slide groove 418 under the rotation of the annular turning handle 401, when the driving plate 409 rotates to the bottom of the arch track 412, the driving plate 409 is continuously raised under the action of the arch track 412, and when the first arc piston plate 415 is attached to the inner side of the second arc piston plate 416, the limiting clamping plate 420 is in the inner groove of the first arc piston plate 415 and is parallel to one side of the first arc piston plate 415. When the arc piston block 407 is separated from the first arc piston plate 415 during the rising process, the second arc piston plate 416 is in the Under the action of the limiting clamping plate 420, it presses against the outer wall of the arc-shaped piston block 407. At this time, the second compression spring 417 is no longer subjected to external force, and pushes the first arc-shaped piston plate 415 to reset, thereby opening the first circular hole 423 and the second circular hole 424, so that the negative pressure inside the second rubber hose 303 can be automatically discharged through the rectangular through hole 402, thereby avoiding pushing air into the nasal cavity during the resetting process of the first arc-shaped piston plate 415 and the second arc-shaped piston plate 416, thereby irritating the nasal cavity of the gastric tube patient and causing discomfort to the patient, so that the device can suction the patient's nasal cavity in a gentle suction manner, thereby improving the overall practicality of the device.

[0049] When the arc piston block 407 is separated from the first arc piston plate 415 during the continued rotation, and then separated from the second arc piston plate 416 during the continued upward movement of the arc piston block 407 along the arch track 412, the arc piston block 407 will continue to move upward along the arch track 412 until it shrinks to the inner side of the sealing ring 406. When the arc piston block 407 passes over the reset plate 421, the arc piston block 407 moves from the top to the lowest point of the arch track 412 during the continued rotation, so that the arc piston block 407 is reset to the initial position and then contacts with another set of first arc piston plates 415 and second arc piston plates 416, and the above operation is repeated to continue to form suction. Through the cooperation of the above multiple parts, the annular turning handle 401 is continuously rotated in a circle, and unidirectional suction is formed on the inside of the second rubber hose 303, thereby improving the suction efficiency of sputum in the nasal cavity and improving the overall practicality of the device.

[0050] The working process of the technical solution of the present invention is as follows:

[0051] First, when suctioning is performed on a patient with a gastric tube, the expectorant mechanism 4 is operated to generate suction on the inner side of the second rubber hose 303, thereby generating negative pressure inside the corrugated hose 302. Due to the pressure difference inside the corrugated hose 302, the sputum in the nasal cavity can be sucked into the inner side of the corrugated hose 302 through the Z-shaped through hole 307, and the corrugated hose 302 reciprocates in expansion and contraction during the reciprocating suction process of the expectorant mechanism 4.

[0052] After the sputum is sucked into the inner side of the corrugated hose 302, it slides downward along the inner tube wall of the corrugated hose 302 under the action of gravity and suction. When the sputum moves to the fluid exchange port at the bottom of the second rubber hose 303, the sputum will fall into the fluid collection box 308 along the tube wall of the fluid exchange port. Finally, it can move along the discharge port of the fluid exchange pot 309 to the bottom of the fluid exchange pot 309 for collection. When the sputum accumulates to two-thirds of the fluid exchange pot 309, the fluid exchange pot 309 can be removed by rotating the fluid exchange pot 309 to clear the sputum inside, thereby achieving the removal of the sputum.

[0053] When the staff inserts the gastric tube 2 into the sleeve 310 and passes it through the first rubber hose 301 into the body of the gastric tube patient and needs to fix the gastric tube 2, the staff can rotate the squeezing cap 304 and screw it into the inner side of the gastric tube connector 305 to squeeze the annular airbag 306, so that the annular airbag 306 presses the gastric tube and improves the sealing performance of the sleeve 310.

[0054] When a patient with a gastric tube needs to remove fluid and suction phlegm, the staff can rotate the annular handle 401 to drive the rotating ring 404 to rotate, thereby driving the sliding column 408 to rotate, so that the driving plate 409 drives the arc piston block 407 to move. When the arc piston block 407 contacts the first arc piston plate 415, the first arc piston plate 415 is pushed to move toward the second arc piston plate 416. When the first arc piston plate 415 is attached to the outer wall of the second arc piston plate 416, the first circular hole 423 and the second circular hole 424 are blocked, so that the space between the reset plate 421 and the second arc piston plate 416 forms a closed environment, so that the arc piston block 407 continues to rotate, and during the process of pushing the first arc piston plate 415 toward the second arc piston plate 416 and rotating toward the reset plate 421, the second rubber hose 303 can be sucked, so that the sputum inside the nasal cavity is sucked into the second rubber hose 303.

[0055] When the driving plate 409 continues to rotate along the limiting slide groove 418 under the rotation of the annular turning handle 401, when the driving plate 409 rotates to the bottom of the arched track 412, the driving plate 409 continues to rise under the action of the arched track 412, and when the first arc piston plate 415 is attached to the inner side of the second arc piston plate 416, the limiting clamping plate 420 is in the inner groove of the first arc piston plate 415 and is parallel to one side of the first arc piston plate 415. When the arc piston block 407 is separated from the first arc piston plate 415 during the rising process, the second arc piston plate 416 is pressed against the outer wall of the arc piston block 407 under the action of the limiting clamping plate 420. At this time, the second compression spring 417 is no longer subjected to external force, pushing the first arc piston plate 415 to reset, thereby opening the first circular hole 423 and the second circular hole 424, so that the negative pressure inside the second rubber hose 303 can be automatically discharged through the rectangular through hole 402.

[0056] When the arc piston block 407 is separated from the first arc piston plate 415 as it continues to rotate, and then separates from the second arc piston plate 416 as it continues to move upward along the arch track 412, the arc piston block 407 will continue to move upward along the arch track 412 until it shrinks to the inner side of the sealing ring 406. When the arc piston block 407 passes over the reset plate 421, the arc piston block 407 moves from the top to the lowest point of the arch track 412 as it continues to rotate, so that the arc piston block 407 is reset to the initial position and then contacts with another set of first arc piston plate 415 and second arc piston plate 416, and the above operation is repeated to continue to form suction. Through the cooperation of the above multiple parts, one-way suction is formed on the inside of the second rubber hose 303 during the continuous circular rotation of the annular turning handle 401.

[0058] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
