Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a unilateral oxygen inhalation tube for patients with a nasogastric tube. Background Art

[0002] Oxygen inhalation refers to the provision of additional oxygen to the human body through special equipment. The current methods of oxygen inhalation mainly include nasal cannula oxygen inhalation, bilateral nasal cannula oxygen supply, nasal congestion method and mask method.

[0003] Nasal cannula oxygenation: There are two methods: unilateral nasal cannula oxygenation and bilateral nasal cannula oxygenation. Unilateral nasal cannula oxygenation requires the nasal cannula to be inserted two-thirds of the way from the nose tip to the earlobe, through the nasal cavity to the nasopharynx. This method is difficult for patients to tolerate, and the cannula puts pressure on the nasal cavity and is easily blocked by secretions, so it is not commonly used in clinical practice.

[0004] Bilateral nasal cannula oxygenation: bilateral nasal cannulae are inserted about 1 cm into the nostrils and the cannula rings are fixed securely. This method is relatively simple, comfortable, and easily accepted by patients. It is also one of the most commonly used methods of oxygenation in clinical practice. However, it is not suitable for situations where one nasal cavity is occupied by a gastric tube.

[0005] Nasal plug method: It is a method of administering oxygen by inserting a nasal plug into the nasal vestibule of one nostril. This method is less irritating, more comfortable for the patient, and both nostrils can be used alternately. However, for patients with a nasogastric tube and a nasointestinal tube indwelling on one side, the nasal plug is plugged in the nostril when inhaling oxygen through the nasal plug. On the one hand, the oxygen blowing area is larger than that of the nasal cannula; on the other hand, the exhaled CO2 is blocked by the nasal plug, causing the secretions here to form sputum crusts due to the long-term blowing of the two gases, blocking the nasal cavity, which reduces the comfort level.

[0006] The mask method provides oxygen to the patient's mouth and nose, with oxygen entering through the bottom and exhaled air exiting through holes on both sides. This method is more effective because oxygen can be inhaled through both the mouth and nose. However, this method can affect the patient's eating and speaking, often causing fog inside the mask and causing discomfort. It also increases the risk of aspiration of vomitus during vomiting. Utility Model Content

[0007] The utility model aims to provide a unilateral oxygen inhalation tube for patients with a nasogastric tube, which increases the comfort of the patients.

[0008] To achieve the above objectives, the technical solution of the present utility model is as follows.

[0009] A unilateral oxygen inhalation tube for patients with a nasogastric tube includes a main tube, one end of which is equipped with a connector, the other end of which is connected to two branch tubes via a tap, the ends of the two branch tubes being commonly connected to a switching tube, the outer surface of which is connected to a nasal catheter, the outer surface of which is provided with an N-shaped portion, and the outer surfaces of the two branch tubes being provided with clamping mechanisms.

[0010] It can be seen that the setting of the nasal catheter can achieve the purpose of unilateral oxygen inhalation for the patient, and the setting of the N-shaped part can allow the gastric tube to pass through it from under it, which is convenient for passing the nasogastric tube and fixing it. Compared with nasal obstruction, the nasal catheter cavity is smaller, has strong compliance and soft texture, which can reduce irritation to the nasal mucosa. At the same time, the patient feels more comfortable and will not pull the catheter, which increases the patient's compliance with oxygen inhalation and improves the patient's satisfaction. In addition, the setting of the clamping mechanism can lock and fix the two branches, improve the stability of the oxygen tube when worn, and avoid loosening and slipping.

[0011] Furthermore, the clamping mechanism includes an upper clamping block and a lower clamping block, the upper surface of the lower clamping block is connected to two limit rods, and the upper clamping block is slidably installed on the outside of the limit rods, the interior of the upper clamping block is penetrated and threadedly connected with a screw, and the end of the screw is rotatably connected to the lower clamping block.

[0012] When wearing, first turn the screw to drive the upper clamping block away from the lower clamping block, cancel the clamping of the branch tube, then pass the two branch tubes from behind the ears and extend to the chin, then slide the upper clamping block and the lower clamping block to the chin and adjust the tightness, then turn the screw to drive the upper clamping block to move toward the lower clamping block, and lock the branch tube to improve the wearing stability of the oxygen inhalation tube and avoid loosening and slipping.

[0013] Furthermore, baffles are provided on the outer surfaces of both sides of the nasal catheter.

[0014] Since a gastric tube is installed in one nostril of the patient, he can only breathe through the nostril with the nasal catheter inserted. The setting of the baffle can prevent the nasal catheter from moving deep into the nostril during the patient's activities, thereby preventing the adapter tube from being blocked on the outside of the nostril and causing the patient to have difficulty breathing. It ensures that there is a gap in the nostril communicating with the outside world, and the exhaled CO2 can be exhaled directly into the air, and is not easy to stay at the nasal outlet. Nasal secretions are not easy to accumulate in the nasal cavity, thus avoiding the formation of sputum crusts.

[0015] Furthermore, the inner walls of the upper clamping block and the lower clamping block are both provided with rubber pads, and the outer surfaces of the rubber pads are provided with anti-slip grooves.

[0016] The softness of the rubber pad can reduce direct pressure on the branch pipe and reduce wear or indentation on its surface, thereby protecting the integrity and function of the branch pipe. In addition, the anti-slip groove setting can provide better friction, making the branch pipe more stable and preventing sliding or displacement during use.

[0017] Furthermore, the number of the n-shaped portions is two, and the two n-shaped portions are respectively arranged on both sides of the nasal catheter.

[0018] By providing the two N-shaped parts, the device can be used by patients with gastric tubes placed in the left or right nostrils.

[0019] Furthermore, the distance from the baffle to the end of the nasal catheter is 1 cm.

[0020] Since the insertion depth of the nasal cannula is only 1 cm, it is less likely to compress the nasal vestibule than oxygen administration through nasal congestion; at the same time, there is a gap in the nasal cavity, so patients are less likely to experience nasal congestion or suffocation.

DETAILED DESCRIPTION

[0026] The present invention is described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-4 As shown, a unilateral oxygen inhalation tube for patients with a nasogastric tube includes a main tube 100, one end of which is installed with a connector 106, the other end of which is connected to two branch tubes 102 via a tap 101, the ends of the two branch tubes 102 are connected to a transfer tube 103, the outer surface of which is connected to a nasal catheter 104, the outer surface of which is provided with an N-shaped portion 105, and the outer surfaces of the two branch tubes 102 are provided with a clamping mechanism 200.

[0028] During use, the connector 106 is connected to the oxygen supply device, the adapter tube 103 is placed under the patient's nasal cavity, and the nasal catheter 104 is inserted into the patient's nostril. At the same time, the gastric tube of the other nostril is clamped on the inner side of the N-shaped portion 105. Then, the two branches 102 are passed around the back of the ear and extended to the chin. Then, the branches 102 are locked and fixed by the clamping mechanism 200, thereby improving the wearing stability of the oxygen tube and avoiding loosening and slipping, thereby achieving the purpose of unilateral oxygen inhalation of the patient. Compared with nasal congestion, the nasal catheter 104 has a smaller cavity, strong compliance, and soft texture, which can reduce irritation to the nasal mucosa. At the same time, the patient feels more comfortable and will not pull the catheter, which increases the patient's compliance with oxygen inhalation and improves patient satisfaction.

[0029] The upper clamping block 201 and the lower clamping block 202 are connected to each other, and the upper clamping block 201 is slidably mounted on the outer side of the limit rod 203. The interior of the upper clamping block 201 is penetrated and threadedly connected with a screw 204. The end of the screw 204 is rotatably connected to the lower clamping block 202. When wearing, the screw 204 is first turned to drive the upper clamping block 201 away from the lower clamping block 202 to cancel the clamping of the branch tube 102. Then, the two branch tubes 102 are passed around the back of the ear and extended to the chin. Then, the upper clamping block 201 and the lower clamping block 202 are slid to the chin and the tightness is adjusted. Then, the screw 204 is turned to drive the upper clamping block 201 to move toward the lower clamping block 202 and lock the branch tube 102. This can improve the wearing stability of the oxygen inhalation tube and avoid loosening and slipping.

[0030] Specifically, baffles 300 are provided on the outer surfaces of both sides of the nasal catheter 104. Since a gastric tube is provided in one nostril of the patient, the patient can only breathe through the nostril where the nasal catheter 104 is inserted. The provision of the baffles 300 can prevent the nasal catheter 104 from moving deep into the nostril during the patient's activities, thereby preventing the adapter tube 103 from being blocked on the outside of the nostril, causing the patient to have difficulty breathing. It ensures that there is a gap in the nostril to communicate with the outside world, so that the exhaled CO2 can be directly exhaled into the air and is not likely to stay at the nasal outlet. Nasal secretions are not likely to accumulate in the nasal cavity, thus avoiding the formation of sputum crusts.

[0031] Specifically, the inner walls of the upper clamping block 201 and the lower clamping block 202 are both provided with rubber pads 400, and the outer surfaces of the rubber pads 400 are provided with anti-slip grooves. The softness of the rubber pads 400 can reduce the direct pressure on the branch pipe 102 and reduce the wear or indentation on its surface, thereby protecting the integrity and function of the branch pipe 102. In addition, the setting of the anti-slip grooves can provide better friction, making the branch pipe 102 more stable and preventing sliding or displacement during use.

[0032] Specifically, there are two n-shaped portions 105 , and the two n-shaped portions 105 are respectively arranged on both sides of the nasal catheter 104 . With the arrangement of the two n-shaped portions 105 , the nasal catheter can be used by patients with gastric tubes placed in either nostril.

[0033] Specifically, the distance from the baffle 300 to the end of the nasal cannula 104 is 1 cm. Since the insertion depth of the nasal cannula 104 is only 1 cm, the nasal cannula 104 is less likely to compress the nasal vestibule compared to oxygen administration with nasal congestion; at the same time, there is a gap in the nasal cavity, so the patient is less likely to feel nasal congestion or suffocation.

[0034] The above is a detailed description of the present invention in conjunction with specific embodiments, and the specific implementation methods of the present invention are not limited to these descriptions. For those skilled in the art of the present invention, if a number of equivalent substitutions or obvious modifications are made without departing from the concept of the present invention and have the same performance or use, they should be considered to fall within the scope of patent protection of the present invention as determined by the submitted claims.
