Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an oxygen inhalation tube that is convenient and comfortable to use. Background Technology

[0002] An oxygen cannula is a medical device that connects the nose to an oxygen supply device, mainly consisting of an extension tube and a wearing part. The wearing part includes two shunt tubes that extend into the nasal cavity. Oxygen is delivered to the patient through the shunt tubes after being transported through the extension tube.

[0003] In clinical practice, many patients require gastric tubes to deliver fluids and food. Most existing oxygen tubing is double-lumen, meaning the gastric tube and one of the shunt tubes must be inserted into the patient's nasal cavity simultaneously. Having two tubes in one nasal cavity can cause discomfort. Removing one shunt tube causes the entire fitting to tilt, making it prone to falling off and causing discomfort. Furthermore, the external shunt tube continues to output oxygen, resulting in oxygen waste, risks, and inconvenience.

[0004] Therefore, this application proposes an oxygen inhalation tube that is convenient and comfortable to use, in order to improve ease of use and patient comfort. Utility Model Content

[0005] In view of the shortcomings of the prior art mentioned above, the purpose of this utility model is to provide an oxygen inhalation tube that is convenient and comfortable to use, in order to solve the problem of inconvenience in inserting a gastric tube mentioned in the prior art.

[0006] To achieve the above and other related objectives, this utility model provides a convenient and comfortable oxygen inhalation tube, comprising:

[0007] The gas distribution unit has extension pipes connected to both ends, and the extension pipes can be connected to external oxygen supply equipment to transmit oxygen into the gas distribution unit.

[0008] Two shunt sections are installed on the gas distribution section in a rotatable manner. The shunt sections can be rotated to control the oxygen delivery of the shunt sections and to make room for the external gastric tube to be inserted into the nasal cavity.

[0009] Preferably, the gas distribution unit includes an oxygen relay pipe, and both sides of the outer surface of the oxygen relay pipe are provided with limiting grooves, and each limiting groove is provided with an air outlet.

[0010] Both ends of the oxygen relay tube are equipped with connecting tubes, which are inserted into the extension tube.

[0011] Preferably, the diversion part includes a connecting sleeve, which is rotatably installed in the limiting groove, and the outer surface of the connecting sleeve is provided with a nasal inlet tube that can be inserted into the nasal cavity;

[0012] The inner wall of the connecting sleeve is provided with a protruding air inlet, which is connected to the nasal tube. The air inlet can be inserted into the air outlet, and the size of the air inlet is compatible with that of the air outlet.

[0013] Preferably, the inner wall of the limiting groove is provided with raised damping strips at equal intervals, the inner wall of the connecting sleeve is provided with a recessed damping groove, the damping strips are adapted to the damping groove, and an indicator is provided on the outer surface of the connecting sleeve to indicate the position of the air outlet.

[0014] Preferably, the outer surface of the connecting sleeve is provided with a push plate, and the push plate is at a 90-degree angle to the nasal inlet tube.

[0015] Preferably, each of the nasal intubations has an auxiliary portion at its end in a detachable manner.

[0016] Preferably, the auxiliary part includes an insertion tube, the end of which is provided with a breathable rubber head that can be inserted into the nasal cavity.

[0017] Preferably, the breathable rubber head is rotatably mounted on the end of the insertion tube.

[0018] Preferably, a flow valve is provided at the connection between the insertion tube and the ventilated rubber head, and the flow rate of the flow valve can be controlled by rotating the ventilated rubber head.

[0019] Preferably, the flow valve is divided into a fixed disc and a movable disc, with the fixed disc located at the end of the connector and the movable disc located inside the vented rubber head;

[0020] Both the movable disc and the fixed disc are equipped with air vents. The movable disc overlaps the fixed disc, and the projected area of ​​the movable disc is larger than the air vents on the fixed disc, so that the movable disc can completely seal the fixed disc.

[0021] As described above, the oxygen inhalation tube of this utility model, which is convenient and comfortable to use, has the following beneficial effects:

[0022] 1. This utility model installs two independently rotatable diversion sections on the gas distribution section. Each diversion section can control the oxygen supply by rotation. When a gastric tube needs to be inserted, the diversion section at the corresponding position can be rotated to cut off the oxygen supply and make the diversion section detach from the patient's nasal cavity to leave space for the gastric tube to be inserted, thereby improving the patient's comfort and making the operation very convenient.

[0023] 2. This utility model sets a damping strip inside the limiting groove and a damping groove inside the connecting sleeve. The angle of the connecting sleeve is limited by the cooperation of the damping strip and the damping groove, so that the connecting sleeve will not easily rotate. When the air is supplied, the air inlet will be inserted into the air outlet to further limit the angle of the connecting sleeve, thus achieving the effect of maintaining the stability of the angle of the connecting sleeve.

[0024] 3. This utility model features a connector that is inserted into the nasal tube and a soft, breathable rubber tip that is inserted into the nasal cavity. The soft, breathable rubber tip makes the patient more comfortable and reduces the gap between the tip and the nasal cavity, thereby increasing oxygen intake and reducing oxygen waste.

[0025] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value. Attached Figure Description

[0039] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0040] Please see Figures 1 to 8 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0041] like Figures 1-3 As shown, this utility model provides a convenient and comfortable oxygen inhalation tube, including: a gas distribution section 1 and two diverting sections 2. After oxygen enters the gas distribution section 1, it is supplied to the two nasal cavities through the two diverting sections 2, making it convenient for patients to inhale oxygen. Both ends of the gas distribution section 1 are connected to extension tubes 3, which can be connected to external oxygen supply equipment to transmit oxygen to the gas distribution section 1. During use, the gas distribution section 1 can be worn on the patient's face through the extension tubes 3, so that the diverting sections 2 are located in the patient's nasal cavity.

[0042] Both shunt sections 2 are independently rotatable and mounted on the gas distribution section 1. Rotation of the shunt section 2 controls the on / off flow of oxygen. When a gastric tube needs to be inserted, the shunt section 2 at the corresponding position is rotated according to the nasal cavity to facilitate tube insertion. At this time, the rotated shunt section 2 cuts off oxygen supply to reduce waste and prevent excessive oxygen diffusion into the air, which could pose a risk if exposed to an open flame. Furthermore, this operation can be performed simply by rotating the shunt section 2, improving ease of use.

[0043] like Figure 2As shown, in some embodiments, the gas distribution unit 1 of this utility model includes an oxygen relay pipe 101, with limiting grooves 102 on both sides of the outer surface of the oxygen relay pipe 101. The limiting grooves 102 are used to limit the flow distribution unit 2, so that the flow distribution unit 2 can only rotate within a limited area. Both ends of the oxygen relay pipe 101 are provided with connecting pipes 105, which are inserted into extension pipes 3. The oxygen supplied by the oxygen supply equipment is transmitted to the interior of the oxygen relay pipe 101 through the extension pipe 3. Each limiting groove 102 is provided with an air outlet 103. The oxygen input into the oxygen relay pipe 101 is split through the two air outlets 103, allowing the oxygen to enter the corresponding flow distribution unit 2, and then approach the patient's nasal cavity for the patient to inhale oxygen.

[0044] like Figures 2-5 As shown, in some embodiments, the diversion part 2 of this utility model includes a connecting sleeve 201, which is rotatably installed in the limiting groove 102. In this case, the inner wall of the connecting sleeve 201 and the inner wall of the limiting groove 102 are fitted and sealed to prevent oxygen leakage from the connection between the connecting sleeve 201 and the limiting groove 102. The outer surface of the connecting sleeve 201 is provided with a nasal inlet 202 that can be inserted into the nasal cavity. The inner wall of the connecting sleeve 201 is provided with a protruding air inlet 203, which communicates with the nasal inlet 202. When oxygen is diverted from the air outlet 103, the oxygen is transmitted through the nasal inlet 202 to the patient's nasal cavity or nearby for oxygen inhalation. The air inlet 203 can be inserted into the interior of the air outlet 103, and the size of the air inlet 203 is adapted to the size of the air outlet 103. When the gas inlet 203 and the gas outlet 103 are connected, a relatively sealed channel can be formed, which can effectively reduce oxygen leakage.

[0045] The gas inlet 203 is a flexible channel tube that can deform under pressure. Therefore, after rotating the connecting sleeve 201, the gas inlet 203 will deform under pressure, allowing the connecting sleeve 201 to rotate. Furthermore, when the gas inlet 203 deforms, it squeezes the opening of the gas inlet 203 to form a self-sealing seal, cutting off the oxygen output. To further prevent leakage from the outlet 103, a solid sealing block of the same size as the gas inlet 203 can be provided on the inner wall of the connecting sleeve 201 away from the gas inlet 203. When the gas inlet 203 rotates to the back of the outlet 103, the sealing block engages inside the outlet 103 to continue sealing. The sealing block is not shown in the attached drawing.

[0046] like Figure 2As shown, in some embodiments, the inner wall of the limiting groove 102 of this invention is provided with raised damping strips 104 at equal intervals, and the inner wall of the connecting sleeve 201 is provided with recessed damping grooves 204. The damping strips 104 and damping grooves 204 are adapted to each other, and an indicator 106 is provided on the outer surface of the connecting sleeve 201 to indicate the position of the vent 103, so as to avoid the air inlet 203 not being aligned with the vent 103 when air is supplied. After the connecting sleeve 201 rotates, the damping strips 104 and damping grooves 204 cooperate to increase the resistance to the rotation of the connecting sleeve 201. This can effectively prevent the connecting sleeve 201 from rotating on its own, which would lead to unstable air supply and sealing. Moreover, after the connecting sleeve 201 is rotated, the air inlet 203 can be moved away from the vent 103 and placed between two adjacent damping strips 104, thus blocking the vent 103 and the air inlet 203.

[0047] like Figure 2 and Figure 4 As shown, in some embodiments, a push plate 205 is provided on the outer surface of the connecting sleeve 201 of this utility model. Rotation of the connecting sleeve 201 can be achieved by pushing the push plate 205, thereby improving the ease of rotation. The push plate 205 is at a 90-degree angle to the nasal intubation tube 202. After rotating the nasal intubation tube 202 180 degrees, the push plate 205 can rotate from directly upward to directly downward, avoiding obstruction of the insertion of the gastric tube and facilitating rotation of the push plate 205.

[0048] like Figures 1-4 As shown, in some embodiments, each nasal inlet 202 of this invention has a detachable auxiliary part 4 at its end. The auxiliary part 4 serves to improve the stability of the connection between the nasal inlet 202 and the nasal cavity. Furthermore, the soft auxiliary part 4 enhances patient comfort.

[0049] Specifically, the auxiliary part 4 of this utility model includes an insertion tube 401, which can be inserted into the nasal inlet tube 202 and connected to it. A breathable rubber head 402 is provided at the end of the insertion tube 401. The breathable rubber head 402 can be inserted into the nasal cavity. The soft breathable rubber head 402 provides a more comfortable experience for the patient compared to the relatively rigid nasal inlet tube 202. Furthermore, the breathable rubber head 402 reduces the gap between itself and the nasal cavity, reducing oxygen leakage while allowing the body to breathe, thus improving oxygen utilization.

[0050] like Figures 6-8As shown, in some embodiments, the breathable rubber head 402 of this invention is rotatably mounted on the end of the insertion tube 401. A flow valve 403 is provided at the connection between the insertion tube 401 and the breathable rubber head 402, and the flow rate of the flow valve 403 can be controlled by rotating the breathable rubber head 402. When the patient is receiving oxygen, the oxygen delivery rate can be adjusted according to needs. For example, if the patient only needs mild oxygen inhalation, the ventilation between the flow valves 403 can be reduced, thus reducing oxygen input. If the patient only needs oxygen inhalation through one nostril, one side of the nasal inlet 202 can be closed to improve fit. At the same time, the flow valve 403 can also assist in the oxygen cut-off performance after the connecting sleeve 201 is rotated, preventing the air outlet 103 from failing to disengage properly from the air inlet 203, thus ensuring proper oxygen delivery.

[0051] Specifically, the flow valve 403 of this utility model consists of a fixed disc and a movable disc. The fixed disc is located at the end of the connector 401, and the movable disc is located inside the venting rubber head 402. Both the movable and fixed discs are provided with airflow holes, and the movable disc overlaps the fixed disc. By rotating the venting rubber head 402, the angle between the movable and fixed discs can be changed, thereby changing the cross-section of the airflow holes and adjusting the oxygen supply. Furthermore, the projected area of ​​the movable disc is larger than the airflow holes on the fixed disc, allowing the movable disc to completely seal the fixed disc. When the movable disc rotates, it can completely seal the airflow holes on the fixed disc, achieving the effect of completely cutting off the oxygen supply.

[0052] The specific usage process of this utility model is as follows:

[0053] The entire device is worn on the patient's face through the gas distribution unit 1 and connected to the oxygen supply equipment through the gas distribution unit 1;

[0054] Insert the breathable rubber head 402 into the patient's nasal cavity, and oxygen will be delivered to the patient's nasal cavity through the breathable rubber head 402 for the patient to inhale oxygen;

[0055] When a gastric tube needs to be inserted, rotate the connecting sleeve 201 on the corresponding side to disengage the ventilated rubber head 402 from the nasal cavity side. At this time, the air outlet 103 and the air inlet 203 separate and cut off the oxygen supply to the nasal tube 202 after rotation.

[0056] And rotate the ventilated rubber head 402 for further oxygen deprivation;

[0057] A gastric tube is inserted into the empty nasal cavity to supply water or food.

[0058] In summary, the oxygen inhalation tube of this utility model is convenient and comfortable to use. By installing two independently rotatable diversion sections 2 on the gas distribution section 1, the oxygen supply can be controlled by rotating each diversion section 2. When a gastric tube needs to be inserted, the corresponding diversion section 2 can be rotated to cut off the oxygen supply and remove the diversion section 2 from the patient's nasal cavity to make room for the gastric tube to be inserted, thereby improving the patient's comfort and making the operation very convenient.

[0059] This invention provides a damping strip 104 inside the limiting groove 102 and a damping groove 204 inside the connecting sleeve 201. The damping strip 104 and the damping groove 204 work together to limit the angle of the connecting sleeve 201, preventing the connecting sleeve 201 from rotating easily. Furthermore, when supplying air, the air inlet 203 is inserted into the air outlet 103 to further limit the angle of the connecting sleeve 201, thus achieving the effect of maintaining the stability of the angle of the connecting sleeve 201.

[0060] This invention features a connector 401 that is inserted into the nasal inlet tube 202, and a soft, breathable rubber tip 402 that is inserted into the nasal cavity. The soft, breathable rubber tip 402 makes the patient more comfortable and reduces the gap between the tip and the nasal cavity, thereby increasing oxygen intake and reducing oxygen waste.

[0061] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0062] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
