Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a nasal tracheal tube fixing device. BACKGROUND

[0002] Nasal tracheal intubation is a commonly used method in medical practice, mainly used to keep the airway of patients unobstructed, especially in cases where respiratory support or anesthesia is required. However, during the use of nasal tracheal intubation, a key problem is how to effectively fix the tube to prevent it from falling off or shifting, while ensuring the comfort of the patient.

[0003] Currently, the mainstream fixing method is to use adhesive tape to directly paste the tube on the patient's face. This fixing method can stabilize the tube to a certain extent, but the adhesive tape pasted on the skin for a long time can cause discomfort to the patient, including redness, itching and even pain, which not only increases the patient's pain, but also may affect their acceptance and compliance of treatment. Secondly, the adhesive tape fixing method lacks sufficient flexibility and is difficult to adapt to the slight movement or shape change of the patient's face, which may cause the tube to loosen or shift during the fixing process, thereby affecting the effect of respiratory support.

[0004] Therefore, the present application provides a nasal tracheal tube fixing device to solve the above problems. CONTENT OF THE INVENTION

[0005] The present application provides a nasal tracheal tube fixing device, which aims to solve the problem that the existing tube is usually fixed on the patient's face with adhesive tape, which can stabilize the tube to a certain extent, but the adhesive tape pasted on the skin for a long time can cause discomfort to the patient, including redness, itching and even pain, which not only increases the patient's pain, but also may affect their acceptance and compliance of treatment.

[0006] To achieve the above purpose, the present application provides the following technical solution: a nasal tracheal tube fixing device, comprising a tube body and a fixing device for fixing the tube body at the patient's nostrils;

[0007] In order to facilitate the fixation of the cannula body at the nostril of the patient: the fixing device comprises a elastic ball sleeved on the cannula body, a bandage symmetrically arranged on both sides of the elastic ball, a Velcro hook face fixedly arranged on the outer side of one end of the bandage away from the elastic ball, and a Velcro loop face fixedly arranged on the outer side of one end of the other bandage away from the elastic ball; wherein the bandage is provided with two groups, and the two groups of bandages pass through the upper and lower parts of the patient's ears to avoid the ears to avoid pressure injury to the patient's ears. Through the design of elastic ball and soft and breathable bandage, the irritation of the cannula to the nostril and face of the patient is reduced, and the comfort of the patient is improved. The close contact of the elastic ball with the nostril and the fixing mode of the bandage by passing around the upper and lower parts of the ear to fix on the head of the patient together ensure the stable position of the cannula body in the nostril of the patient, and reduce the risk of falling off or displacement of the cannula. The design of Velcro makes the fixation and release of the bandage simple and fast, and the medical staff can quickly complete the fixation work of the cannula body, and the work efficiency is improved.

[0008] Preferably, the elastic ball is made of medical grade TPE material. TPE material has good elasticity, softness and wear resistance, which can ensure that the elastic ball maintains stable shape and performance during long-term wearing.

[0009] Preferably, in order to improve the adaptability of the elastic ball to the nostril of the patient: the end of the elastic ball away from the nostril of the patient is spherical, and the end of the elastic ball close to the nostril of the patient is conical cylindrical. By optimizing the shape of the elastic ball, the irritation and friction of the cannula to the nostril of the patient are reduced, and the comfort of the patient is further improved. The design of conical cylindrical shape makes the elastic ball fit the inner wall of the nostril more closely, reduces the risk of falling off or displacement of the cannula, and improves the stability of fixation.

[0010] Preferably, in order to facilitate the connection of the elastic ball and the cannula body: a through hole is formed in the elastic ball for the insertion of the cannula body. By forming the through hole, the connection between the elastic ball and the cannula body is more close and stable, and the risk of falling off or displacement of the cannula during use is reduced.

[0011] Preferably, in order to improve the stability of the connection between the cannula body and the through hole: a plurality of convex balls are fixedly connected in the through hole, and the outer wall of the convex ball is in contact with the outer wall of the cannula body. Through the design of convex ball, the connection between the cannula body and the elastic ball is more close and stable, which effectively prevents the risk of falling off or displacement of the cannula during use.

[0012] Preferably, in order to facilitate the connection of the bandage and the elastic ball: a fixing seat is fixedly connected to the end of the bandage close to the elastic ball, and the fixing seat is fixedly connected with the elastic ball. Through the design of fixing seat, the connection between the bandage and the elastic ball is more close and stable, which effectively prevents the risk of loosening or falling off of the bandage during use.

[0013] The present application reduces the irritation of the patient's nostrils and face by the cannula, improves the comfort of the patient, through the design of the elastic ball and the soft and breathable strap. The close contact of the elastic ball with the nostrils, and the fixing method of the strap by passing around the upper and lower parts of the ear to fix on the patient's head, together ensure the stable position of the cannula body in the patient's nostrils, reduce the risk of cannula falling off or displacement. The design of the magic tape makes the fixing and releasing of the strap simple and fast, and the medical staff can quickly complete the fixing work of the cannula body, improving the work efficiency.

[0018] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0019] The present embodiment provides a nasal tracheal cannula fixator, as shown in the figure, which includes a cannula body 1 and a fixing device 2 for fixing the cannula body 1 at the patient's nostrils; Figures 1-2

[0020] ​In order to facilitate the fixation of the cannula body 1 at the nostrils of the patient: the fixing device 2 includes an elastic ball 21 sleeved on the cannula body 1, two straps 22 symmetrically arranged on both sides of the elastic ball 21, a Velcro hook surface 23 fixedly arranged on the outer side of one end of one of the straps 22 away from the elastic ball 21, and a Velcro loop surface 24 fixedly arranged on the outer side of one end of the other strap 22 away from the elastic ball 21; wherein the straps 22 are provided in two groups, and the two groups of straps 22 are respectively passed through the upper and lower parts of the patient's ears to avoid the ears to avoid causing pressure damage to the patient's ears. Through the design of the elastic ball 21 and the soft and breathable straps 22, the irritation of the cannula to the patient's nostrils and face is reduced, and the comfort of the patient is improved. The close contact of the elastic ball 21 with the nostrils, as well as the fixing method of the straps 22 by passing around the upper and lower parts of the ears to the patient's head, together ensure the stable position of the cannula body 1 in the patient's nostrils, reducing the risk of cannula falling off or displacement. The design of the Velcro makes the fixing and releasing of the straps 22 simple and quick, and medical staff can quickly complete the fixing work of the cannula body 1, improving the work efficiency. When in use, first, the cannula body 1 is inserted into the patient's nostrils, with one end of the elastic ball 21 inserted into the patient's nostrils at the same time. Then, the two groups of straps 22 are respectively passed through the upper and lower ends of the patient's ears to the back of the patient's head from both sides of the patient's face. In this process, the design of the straps 22 ensures that they can avoid the ears, thereby avoiding causing pressure damage to the patient's ears. Finally, through the adhesive effect of the Velcro hook surface 23 and the Velcro loop surface 24, the straps 22 are fixed, thereby completing the position fixation of the cannula body 1.

[0021] Specifically, the elastic ball 21 is made of medical-grade TPE material. TPE material has good elasticity, softness and wear resistance, which can ensure that the elastic ball 21 maintains stable shape and performance during long-term wearing. At the same time, the medical-grade TPE material has excellent biocompatibility and will not cause irritation or allergic reaction to the patient's skin, thereby ensuring the safety of the patient.

[0022] Further, to improve the adaptability of the elastic ball 21 to the patient's nostrils: the end of the elastic ball 21 away from the patient's nostrils is spherical in shape, and the end of the elastic ball 21 close to the patient's nostrils is conical cylindrical in shape. By optimizing the shape of the elastic ball 21, the irritation and friction of the cannula to the patient's nostrils are reduced, further improving the patient's comfort. The conical cylindrical design allows the elastic ball 21 to fit more closely to the inner wall of the nostril, reducing the risk of the cannula falling off or shifting, and improving the stability of the fixation. The conical cylindrical design also helps to improve the sealing between the cannula and the nostril, reducing air leakage, thereby improving the effect of respiratory support. The spherical end of the elastic ball 21 makes it smoother when inserted into the nostril, reducing the patient's pain and discomfort. In use, first insert the cannula body 1 into the patient's nostril, at this time the conical cylindrical end of the elastic ball 21 will first enter the nostril, due to its shape design, it can more smoothly slide along the inner wall of the nostril until it is completely inserted. Subsequently, the spherical end of the elastic ball 21 will remain outside the nostril, connected with the straps 22. Then, the two sets of straps 22 are respectively wound from the upper and lower ends of the patient's ears to the back of the patient's head. In this process, the design of the straps 22 ensures that they can avoid the ears, thereby avoiding pressure damage to the patient's ears. Finally, the straps 22 are fixed by the adhesion of the hook surface 23 and the loop surface 24 of the Velcro, thereby completing the fixation of the position of the cannula body 1.

[0023] Specifically, to facilitate the connection of the elastic ball 21 and the cannula body 1: a through hole 211 is provided on the elastic ball 21 for the insertion of the cannula body 1. By providing the through hole 211, the connection between the elastic ball 21 and the cannula body 1 is more secure and stable, reducing the risk of the cannula falling off or shifting during use. The design of the through hole 211 makes the connection between the elastic ball 21 and the cannula body 1 more simple and quick, and medical staff can quickly complete the installation and removal of the cannula body 1, improving work efficiency. The tight connection also helps to improve the sealing between the cannula and the nostril, reducing air leakage, thereby improving the effect of respiratory support. In use, first align the end of the cannula body 1 with the through hole 211 on the elastic ball 21, then gently insert it until the cannula body 1 completely passes through the through hole 211 and extends out of the other end of the elastic ball 21. At this time, the elastic ball 21 will tightly wrap around the cannula body 1, forming a stable connection.

[0024] Further, in order to improve the stability of the connection between the cannula body 1 and the through hole 211, a plurality of convex balls 3 are fixedly connected in the through hole 211, and the outer wall of the convex ball 3 is in contact with the outer wall of the cannula body 1. Through the design of the convex ball 3, the connection between the cannula body 1 and the elastic ball 21 is more tight and stable, effectively preventing the risk of falling off or displacement of the cannula during use. The design of the convex ball 3 does not increase the complexity of the connection between the cannula body 1 and the elastic ball 21, so medical staff can still quickly complete the installation and disassembly of the cannula body 1.

[0025] Specifically, in order to facilitate the connection between the bandage 22 and the elastic ball 21, the end of the bandage 22 close to the elastic ball 21 is fixedly connected with a fixed seat 221, and the fixed seat 221 is fixedly connected with the elastic ball 21. Through the design of the fixed seat 221, the connection between the bandage 22 and the elastic ball 21 is more tight and stable, effectively preventing the risk of loosening or falling off of the bandage 22 during use. The design of the fixed seat 221 makes the connection between the bandage 22 and the elastic ball 21 more simple and fast, and medical staff can quickly complete the installation and disassembly of the bandage 22, improving the work efficiency. Among them, the fixed seat 221 is made of medical-grade TPE material similar to the elastic ball 21 or other soft, elastic and biocompatible materials. The selection of such materials not only ensures the tight connection between the fixed seat 221 and the elastic ball 21, but also avoids stimulating or allergic reactions to the patient's skin. Due to the design of the fixed seat 221, the connection between the bandage 22 and the elastic ball 21 is more tight and stable, not only improving the stability of the cannula, but also ensuring the safety and comfort of the patient during the respiratory support process. At the same time, the soft and elastic material of the fixed seat 221 also reduces the stimulation and pressure on the patient's skin, further improving the comfort of the patient.

[0026] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can make equivalent replacement or change according to the technical solution and concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
