Description

Technical Field

[0001] This utility model relates to a nasal oxygen tube for preventing pressure sores, belonging to the field of nasal oxygen tube technology. Background Technology

[0002] A nasal oxygen cannula is a commonly used medical device. It consists of a tube body with a nasal cannula that connects to the cannula. During use, the cannula connects to a gas source via the machine end, delivering oxygen through the tube body to the nasal cavity for patients who have lost the ability to breathe spontaneously. To ensure effective insertion into the patient's nasal cavity, the cannula needs to be secured to the patient's face. However, improper control of the tightness often results in pressure injuries to the patient's face. To address this, various nasal oxygen tubes have been developed in the industry. For example, Chinese utility model patent CN219517448U discloses a nasal oxygen tube for preventing pressure sores, specifically disclosing a nasal oxygen tube body used to provide oxygenated breathing to the patient. First pressure-resistant components are provided on both sides of the outer wall of the nasal oxygen tube body to reduce pressure on the patient's face. Second pressure-resistant components are provided on the top of both sides of the outer wall of the nasal oxygen tube body to reduce pressure on the patient's ears. A fixing plate is fixedly connected to the first pressure-resistant pad with adhesive, and one side of the first pressure-resistant pad is in contact with the patient's face. The nasal oxygen tube reduces pressure on the patient's face through a first and a second anti-pressure component. However, the tube still needs to be tightened to secure it to the patient's face. If it is tightened too much, it will still leave pressure marks on the patient's face. Furthermore, when using the nasal oxygen tube, the air inlet is located on the back of the patient, which can easily be pressed when lying down or turning over, thus affecting the patient's oxygen intake. Utility Model Content

[0003] The purpose of this invention is to provide a nasal oxygen tube that prevents pressure sores. This invention can reduce the pressure on the patient's face during installation, and the air inlet is located at the front of the patient to prevent pressure on the trachea.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0021] Example: A nasal oxygen cannula for preventing pressure ulcers, configured as follows Figure 1-4 As shown, the device includes a connector 1, with a flexible tube 2 connected to the air inlet end of the connector 1. A shield 3 is provided on the outer side of the air outlet end of the connector 1. The shield 3 is made of medical-grade silicone, which is soft, skin-friendly, and highly elastic, perfectly conforming to the patient's facial contours to reduce facial pressure and effectively prevent oxygen leakage. An oxygen outlet tube 4 is symmetrically arranged on the inner side of the shield 3, passing through the shield 3 and connecting to the air outlet end of the connector 1. An elastic band 5 is provided along the outer edge of the shield 3, with a pair of ear supports 6 on the elastic band 5. The ear supports 6 are made of ABS engineering plastic, combining durability and lightweight properties to provide stable support for the elastic band 5. A cushioning pad 7 is located on the inner side of the shield 3, below the oxygen outlet tube 4. The cushioning pad 7 is made of foam plastic, which is soft and delicate, effectively cushioning the pressure of the oxygen outlet tube 4 on the patient's face and reducing the risk of pressure sores. Insert the oxygen delivery tube 4 into the patient's nasal cavity and align the cushioning pad 7 with the patient's philtrum. Then, wrap the elastic band 5 around the outside of the head. Adjust the position of the ear support 6 on the elastic band 5 by sliding it, so that the elastic band 5 facing the shield 3 is appropriately tightened and the ear support 6 is inserted into the mastoid process behind the patient's ear. Because the oxygen delivery tube 4 is inserted into the patient's nose and the elastic band 5 is limited by the ear support 6, the elastic band 5 can be fixed without being adjusted too tightly. At the same time, the pressure on the patient at the oxygen delivery tube 4 is buffered by the cushioning pad 7, further reducing the pressure on the patient's face. Then, connect the outer end of the hose 2 to the oxygen delivery device. Oxygen flows out from the oxygen delivery tube 4 into the patient's nasal cavity through the hose 2 and connector 1.

[0022] Preferably, such as Figure 1As shown, the oxygen outlet tube 4 has multiple side holes 8 on its side. The side holes 8 effectively prevent the nasal mucosa from being damaged by gas impact or drying, thus improving the safety of using the nasal oxygen tube.

[0023] Preferably, such as Figure 2 and 4 As shown, the connector 1 includes a vertical tube 20, which is connected to the lower part of the hose 2; a horizontal tube 21 is provided on the upper side of the vertical tube 20, which is connected to the interior of the vertical tube 20; a round tube 22 is rotatably connected to the outer end of the horizontal tube 21, and the round tube 22 is fixedly connected to the baffle 3 and the oxygen outlet tube 4; the round tube 22 is connected to the horizontal tube 21 and the oxygen outlet tube 4 respectively.

[0024] Preferably, such as Figure 1 As shown, the baffle 3 has a slot 9 on one side. The elastic band 5 is fixedly connected to the side of the baffle 3 away from the slot 9; the other end of the elastic band 5 passes through the slot 9; an adjusting buckle 10 is provided between the part of the elastic band 5 that passes through the slot 9 and the part that does not pass through the slot 9. The adjusting buckle 10 is a conventional component and can be obtained commercially. In this embodiment, the adjusting buckle 10 is a clasp. The tightness is controlled by pulling the end of the elastic band 5 out or back in the slot 9, and then it is fixed by the adjusting buckle 10.

[0025] Preferably, such as Figure 3 As shown, the earpiece 6 has a groove 11 at its upper end; the elastic band 5 passes through the groove 11; the earpiece 6 has a threaded hole 12 that communicates with the groove 11; a threaded post 13 is provided in the threaded hole 12, and the threaded post 13 is screwed into the threaded hole 12; an abutment block 14 is provided at the inner end of the threaded post 13, and the abutment block 14 abuts against the elastic band 5; a turntable 15 is provided at the outer end of the threaded post 13. The outer end face of the turntable 15 has a slot 16, which facilitates the rotation of the turntable 15. The turntable 15 can be easily rotated by inserting a fingernail into the slot 16. The earpiece 6 slides on the elastic band 5 through the groove 11. After sliding to a suitable position, the turntable 15 is rotated, causing the threaded post 13 to move inward, thereby causing the abutment block 14 to abut against the elastic band 5, thus fixing the earpiece 6 at that position on the elastic band 5.

[0026] Preferably, the cushioning pad 7 is connected to the shield 3 by adhesive; the upper end of the cushioning pad 7 is provided with an arc groove 17, which is used to prevent the cushioning pad 7 from touching the patient's nose.

[0027] Working principle: Cut a cushioning pad 7 to the appropriate shape and attach it to the shield 3. Then, insert the oxygen delivery tube 4 into the patient's nasal cavity, aligning the cushioning pad 7 with the philtrum. Next, wrap the elastic band 5 around the outside of the head. Adjust the position of the ear supports 6 on the elastic band 5 by sliding, and appropriately tighten the elastic band 5 on the side of the ear supports 6 facing the shield 3, securing it behind the patient's mastoid process. Utilizing the mechanical restraint of the ear supports 6, the elastic band 5 can be fixed without excessive tightening, avoiding excessive pressure on the head. At the same time, the cushioning pad 7, with its soft properties, cushions the pressure of the oxygen delivery tube 4 on the patient's face, further reducing the risk of pressure sores. Finally, connect the outer end of the hose 2 to the oxygen generation device. Oxygen flows through the hose 2 into the connector 1 and then out through the oxygen delivery tube 4 into the patient's nasal cavity. During this process, the multiple side holes 8 on the side of the oxygen delivery tube 4 disperse the airflow, preventing damage to the nasal mucosa due to gas impact or dryness, ensuring safe use.
