Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an anti-clogging oxygen inhalation tube for patients. Background Technology

[0002] Cardiovascular disease is a common disease among the elderly. Elderly cardiovascular patients may experience symptoms such as shortness of breath and fatigue. For patients with shortness of breath, oxygen should be administered. The oxygen inhalation tube delivers oxygen directly into the patient's nasal cavity through the outlet tube. However, during oxygen inhalation, secretions from the patient's nasal cavity can easily enter the nasal tube and block it.

[0003] Existing patent CN219558391U describes an anti-clogging oxygen tube for elderly cardiovascular patients. It utilizes an elastic filter inside the nasal tube to filter and block solid secretions from the patient's nasal cavity, allowing liquid secretions to drain into the connecting tube. This prevents solid secretions from clogging the supply and connecting tubes. Furthermore, a push rod allows for easy removal of solid secretions from the filter surface if they are difficult to remove. Moving the push rod upwards pushes up the filter, allowing the elasticity to push the secretions out of the nasal tube. This facilitates direct removal of the secretions by medical personnel and ensures high cleaning efficiency.

[0004] However, when using an existing patented anti-clogging oxygen tube for elderly cardiovascular patients, the elastic filter in the device cannot be disassembled and cleaned. After long-term contact between the patient's nasal secretions and the elastic filter, the bacteria in the secretions will contaminate the elastic filter, thereby contaminating the incoming oxygen. Utility Model Content

[0005] The purpose of this invention is to provide a patient-proof oxygen inhalation tube that solves the problem that, in the aforementioned device, the elastic filter screen is not removable for cleaning, and after long-term contact between the patient's nasal secretions and the elastic filter screen, the bacteria in the secretions will contaminate the elastic filter screen, thereby contaminating the incoming oxygen.

[0006] To achieve the above objectives, this utility model provides a patient-use anti-clogging oxygen inhalation tube, comprising an oxygen supply tube, an installation tube, a nasal tube, a collection hopper, and an opening and closing device. The installation tube is connected to the oxygen supply tube, the nasal tube is connected to the installation tube, and the collection hopper is connected to the installation tube. The collection hopper is located on the side of the installation tube away from the nasal tube. The opening and closing device is disposed on the collection hopper. The device also includes an anti-clogging device comprising a movable ring, an anti-clogging block, a support ring, a limiting component, and a pushing component. The support ring is fixedly installed inside the nasal tube, the movable ring is slidably installed inside the nasal tube and contacts the support ring, the anti-clogging block is fixedly installed inside the movable ring, the limiting component is installed on the nasal tube, and the pushing component is disposed on the collection hopper.

[0007] The limiting component includes a mounting ring and a limiting rod. The mounting ring is fixedly installed on the outside of the nasal tube, and the limiting rod is slidably installed on the mounting ring and passes through the nasal tube.

[0008] The limiting rod is also provided with a chuck and a retaining ring. The chuck is fixedly installed at one end of the limiting rod, and the retaining ring is sleeved on the other end of the limiting rod.

[0009] The pusher assembly includes a pusher rod and a pusher plate. The pusher rod is slidably mounted on the liquid collection hopper, passes through the mounting tube, and extends into the nose tube. At the same time, the pusher rod is fixedly connected to the anti-clogging block. The pusher plate is fixedly mounted on the pusher rod and is located outside the liquid collection hopper.

[0010] The opening and closing device includes a plug and a base plate. The plug is inserted into the end of the liquid collecting hopper away from the mounting pipe. The base plate is fixedly installed on the plug.

[0011] This utility model discloses a patient-use anti-clogging oxygen inhalation tube. In use, the oxygen inhalation tube is connected to an external oxygen cylinder. Oxygen enters the installation tube through the oxygen inhalation tube and then enters the patient's nasal cavity through the nasal tube, meeting the patient's oxygen needs. Liquid secretions in the patient's nasal cavity enter the collection hopper through the nasal tube and the installation tube. The liquid secretions can be easily cleaned by pulling the plug out of the bottom of the collection hopper. Solid secretions in the patient's nasal cavity enter the nasal tube, and the anti-clogging block on the movable ring blocks them, preventing blockage caused by the continuous falling of solid secretions. By pulling out the retaining ring on the limiting rod and using the chuck to pull the limiting rod out of the installation ring and nasal tube, and then pushing the push rod upwards, the push rod pushes the movable ring and the anti-clogging block out of the upper end of the nasal tube, thus facilitating regular cleaning of the movable ring and the anti-clogging block and preventing continuous contamination of the movable ring and the anti-clogging block by secretions.

Detailed Implementation

[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] The embodiment of this application is as follows:

[0019] Please see Figure 1-3 , Figure 1 This is a schematic diagram of the overall structure of a patient-use anti-clogging oxygen inhalation tube according to this utility model. Figure 2 This is a structural schematic diagram of the anti-clogging device of this utility model. Figure 3 This is a schematic diagram of the structure of the pusher assembly of this utility model.

[0020] This utility model provides a patient-use anti-clogging oxygen inhalation tube: including an oxygen inhalation tube 101, an installation tube 102, a nasal tube 103, a collection hopper 104, and an opening and closing device, and also includes an anti-clogging device, which includes a movable ring 105, an anti-clogging block 106, a support ring 107, a limiting component, and a pushing component. The limiting component includes an installation ring 108 and a limiting rod 109, and the limiting rod 109 is also provided with a chuck 110 and a retaining ring 111. The pushing component includes a pushing rod 112 and a pushing plate 113. The opening and closing device includes a plug 114 and a base plate 115. The aforementioned solution solves the problem that in the aforementioned device, the elastic filter screen is not removable for cleaning, and after long-term contact between the patient's nasal secretions and the elastic filter screen, bacteria in the secretions will contaminate the elastic filter screen, thereby contaminating the incoming oxygen.

[0021] In this embodiment, by releasing the limiting component from the movable ring 105, the pushing component pushes the movable ring 105 and the anti-blocking block 106 upwards, thereby facilitating the periodic cleaning of the movable ring 105 and the anti-blocking block 106 and preventing secretions from causing continuous contamination to the movable ring 105 and the anti-blocking block 106.

[0022] The supporting ring 107 is fixedly installed inside the nasal tube 103, the movable ring 105 is slidably installed inside the nasal tube 103 and contacts the supporting ring 107, the anti-clogging block 106 is fixedly installed inside the movable ring 105, the limiting component is installed on the nasal tube 103, the pushing component is disposed on the liquid collecting hopper 104, the oxygen supply tube 101 is disposed at both ends of the mounting tube 102, the liquid collecting hopper 104 has a conical structure, the anti-clogging block 106 is annularly disposed inside the movable ring 105 with a small gap between them, and the supporting ring 107 is located at the bottom of the movable ring 105. By using the movable ring 105 and the anti-blocking block 106, it is possible to prevent nasal secretions from entering the installation tube 102 through the nasal tube 103 and causing blockage. By releasing the limiting component from limiting the movable ring 105, the pushing component pushes the movable ring 105 and the anti-blocking block 106 upward, so that the pushing rod 112 pushes the movable ring 105 and the anti-blocking block 106 out of the upper end of the nasal tube 103. This facilitates the regular cleaning of the movable ring 105 and the anti-blocking block 106, and prevents secretions from causing continuous contamination to the movable ring 105 and the anti-blocking block 106.

[0023] Secondly, the mounting ring 108 is fixedly mounted on the outside of the nasal tube 103; the limiting rod 109 is slidably mounted on the mounting ring 108 and passes through the nasal tube 103. The mounting ring 108 is fused to the outside of the nasal tube 103. The limiting rod 109 is made of plastic. By inserting the limiting rod 109 into the mounting ring 108 and the nasal tube 103, the movable ring 105 and the anti-blocking block 106 can be limited, preventing the movable ring 105 and the anti-blocking block 106 from sliding out of the upper end of the nasal tube 103 with the patient's breathing.

[0024] Furthermore, the chuck 110 is fixedly installed at one end of the limiting rod 109; the retaining ring 111 is sleeved on the other end of the limiting rod 109. The chuck 110 is made of plastic, and the retaining ring 111 is made of rubber. By setting the chuck 110 and the retaining ring 111, the limiting rod 109 can be prevented from accidentally detaching from the mounting ring 108. At the same time, by pulling the retaining ring 111 off the limiting rod 109, it is easy for the limiting rod 109 to detach from the mounting ring 108.

[0025] Furthermore, the push rod 112 is slidably mounted on the liquid collecting hopper 104, passes through the mounting tube 102, and extends into the nose tube 103. At the same time, the push rod 112 is fixedly connected to the anti-blocking block 106. The push plate 113 is fixedly mounted on the push rod 112 and located outside the liquid collecting hopper 104. The push rod 112 has a cylindrical structure, and the push plate 113 is located at the bottom end of the push rod 112. The push plate 113 drives the push rod 112 to push upward, so that the push rod 112 can push the anti-blocking block 106.

[0026] Finally, the plug 114 is inserted into the end of the collection hopper 104 away from the mounting pipe 102; the chassis 115 is fixedly installed on the plug 114, the plug 114 is made of rubber, and the chassis 115 is fused to the bottom of the plug 114. By plugging and pulling the plug 114 at the bottom of the collection hopper 104, the liquid secretions can be concentrated and discharged from the bottom of the collection hopper 104.

[0027] In this embodiment, during use, the oxygen supply tube 101 is connected to an external oxygen tank. Oxygen enters the installation tube 102 through the oxygen supply tube 101, and then enters the patient's nasal cavity through the nasal tube 103 to meet the patient's oxygen needs. Liquid secretions in the patient's nasal cavity enter the collection hopper 104 through the nasal tube 103 and the installation tube 102. By pulling the plug 114 out from the bottom of the collection hopper 104, it is easy to clean the liquid secretions. After solid secretions in the patient's nasal cavity enter the nasal tube 103, the anti-clogging block 106 on the movable ring 105 will... It acts as a barrier to prevent solid secretions from continuously falling and causing blockage. By pulling out the retaining ring 111 on the limiting rod 109 and pulling the limiting rod 109 out of the mounting ring 108 and the nasal tube 103 through the chuck 110, the push rod 112 is then pushed upward, causing the push rod 112 to push the movable ring 105 and the anti-blocking block 106 out of the upper end of the nasal tube 103. This facilitates the regular cleaning of the movable ring 105 and the anti-blocking block 106, preventing secretions from causing continuous contamination to the movable ring 105 and the anti-blocking block 106.
