Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a nasal catheter fixing device for preventing pressure sores. Background Art

[0002] Clinically, doctors usually use nasogastric tubes to deliver liquid diets to maintain the physiological metabolism of patients who are in a vegetative state, comatose patients and other types of patients who cannot eat independently. In practice, the inner wall of the nasal cavity of such patients is prone to pressure sores due to long-term compression by the nasal catheter. In addition, in order to ensure that the nasogastric tube does not separate from the stomach during nasogastric feeding, the nasogastric tube needs to be fixed. Currently available nasogastric tube fixing devices include: However, these devices are difficult to overcome the problem of pressure sores on the inner wall of the nasal cavity while fixing the position of the nasal catheter. Therefore, how to develop a new nasal catheter fixing device to overcome the above-mentioned problems existing in the prior art is a direction that technicians in this field need to further study. Utility Model Content

[0003] The utility model aims to provide a nasal catheter fixing device for preventing pressure sores, which can fix the position of the nasal catheter and reduce the pressure sores on the inner wall of the nasal cavity caused by long-term use of the nasal catheter.

[0004] The technical solution provided by the utility model is a nasal catheter fixing device for preventing pressure sores, which comprises:

[0005] A nasal cannula, wherein the nasal cannula is a columnar structure with an arc-shaped cross section;

[0006] A flexible belt, one end of which is fixedly connected to the rear end surface of the tube body of the nasal cannula as a whole.

[0007] A nose wing patch is fixedly connected to the rear end of the tube body of the nasal cannula as a whole, and an adhesive layer is provided on the nose wing patch. Specifically, the adhesive layer is provided on a side surface of the nose wing patch facing the patient's nose wing.

[0008] By adopting this technical solution: during the process of nasal feeding, firstly, one end of the nasal catheter is inserted into the patient's nasal cavity until its opening reaches the stomach or intestine. Then, the nasal cannula is inserted into the patient's nasal cavity with the nasal catheter, so that the outer arc surface of the nasal cannula fits the inner top wall and the two side walls of the patient's nasal cavity, and the tail end surface of the tube body of the nasal cannula is located at the patient's nasal cavity opening, and then the nose wing sticker is glued and fixed to the patient's nose wing by using the adhesive layer on the nose wing sticker, so as to achieve the position fixation of the nasal cannula. Then, the flexible belt is wrapped and fixed on the tube body part of the nasal catheter left outside the patient's body, thereby achieving the position fixation of the nasal catheter. At the same time, the tube body part of the nasal catheter located in the patient's nasal cavity fits the outer arc surface of the nasal cannula, so that the nasal cannula is blocked from directly contacting the tube body of the nasal catheter with the inner wall of the patient's nasal cavity, thereby reducing the pressure sores caused by the pressure of the tube body of the nasal catheter on the inner wall of the patient's nasal cavity.

[0009] Preferably, the above-mentioned nasal catheter fixing device further comprises:

[0010] The arch pad is a sheet-like structure with a semicircular protrusion at the upper end, and the lower end of the arch pad is fixedly connected to the rear end surface of the tube body of the nasal cannula as a whole.

[0011] By adopting this technical solution: during nasal feeding, when the nasal cannula is inserted into the nasal cavity, the arch pad fits against the periphery of the patient's nasal cavity (i.e., the skin between the nostril and the nose wing). The arch pad is used to block the direct pressure of the tube body of the nasal cannula outside the nasal cavity on this part of the skin, thereby reducing the occurrence of pressure sores on this part of the skin.

[0012] Preferably, in the above-mentioned nasal catheter fixing device, the nasal cannula includes a soft silicone layer and a hydrocolloid dressing layer; the soft silicone layer is located on one side of the inner arc surface of the nasal cannula, and the hydrocolloid dressing layer is located on one side of the outer arc surface of the nasal cannula.

[0013] By adopting this technical solution: the soft silicone layer is used to support and plasticize the nasal cannula, and the hydrocolloid dressing layer has a certain flexibility, which can effectively buffer the pressure generated by the tube body, and can also quickly absorb the secretions in the nasal cavity, thereby improving the comfort of the patient's nasal cavity.

[0014] Preferably, in the above-mentioned nasal catheter fixing device, the number of the flexible bands is configured to be two, and the two flexible bands are symmetrically connected to both sides of the rear end surface of the tube body of the nasal cannula.

[0015] By adopting this technical solution: during the process of fixing the nasal catheter, the two flexible belts are fixed to the tube body of the nasal catheter located outside the patient's body in a cross-wrapped manner, thereby improving the stability and firmness of the nasal catheter fixation.

[0016] Preferably, in the above-mentioned nasal catheter fixing device, the arch pad comprises a soft silicone layer and a hydrocolloid dressing layer, and the arch pad and the nasal cannula are an integrally formed structure.

[0017] Preferably, in the above-mentioned nasal catheter fixing device, the nose wing sticker is made of 3M elastic tape.

[0018] Preferably, in the above-mentioned nasal catheter fixing device, the flexible belt is made of 3M elastic tape.

[0019] Compared with the prior art, the utility model has the following advantages:

[0020] Firstly, the utility model can fix the position of the nasal catheter and reduce the pressure sores on the inner wall of the nasal cavity caused by long-term use of the nasal catheter.

[0021] Secondly, the utility model can also protect the peripheral skin of the patient's nasal cavity and reduce the pressure sore phenomenon caused by the pressure of the nasal catheter on this part of the skin.

[0022] Finally, the utility model has a simple structure and a simple operation process, and is easy for medical staff to prepare manually and use clinically. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] 100, nasal cannula; 200, flexible belt; 300, arch pad; 400, nose wing patch; 510, soft silicone layer; 520, hydrocolloid dressing layer. DETAILED DESCRIPTION

[0026] The following is an explanation of the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0027] Example 1, please refer to Figure 1 :

[0028] A nasal catheter fixing device for preventing pressure sores comprises: a nasal cannula 100, a flexible belt 200, an arch pad 300, and a nose wing sticker 400.

[0029] Wherein: the nasal cannula 100 is used to extend into the patient's nasal cavity during nasogastric feeding to protect the inner wall of the nasal cavity. Specifically: the nasal cannula 100 is a columnar structure with an arc-shaped cross-section. In this example: the nasal cannula 100 further includes a soft silicone layer 510 located on the inner arc surface, and a hydrocolloid dressing layer 520 located on the outer arc surface. In this example: the cross-section of the soft silicone layer 510 and the cross-section of the hydrocolloid dressing layer 520 are concentric arcs.

[0030] During use, the tail end of the nasal cannula 100 is located close to the nasal opening of the patient. The tail end of the nasal cannula 100 is fixedly connected to the lower end of the arch pad 300, the lower end of the nose wing patch 400, and one end of the flexible band 200.

[0031] In this example, the number of the flexible belts 200 is configured as two, and the two flexible belts 200 are symmetrically connected to the two sides of the tail end surface of the tube body of the nasal cannula 100. The arch pad 300 is a sheet structure with a semicircular protrusion at the upper end. The arch pad 300 also includes a soft silicone layer 510 and a hydrocolloid dressing layer 520, and the arch pad 300 and the nasal cannula 100 are an integrally formed structure. The shape of the upper end of the nose wing sticker 400 is similar to a semicircle. The flexible belt 200 and the nose wing sticker 400 are both made of 3M elastic tape. That is: one side of the belt body of the flexible belt 200 and one side of the nose wing sticker 400 are respectively provided with an adhesive layer. And a layer of oil paper that is easy to tear is provided on each of the adhesive layers. The 3M elastic tape is a well-known tape structure and will not be described in detail in this article.

[0032] It should be noted that the reason why the nasal cannula 100 is designed as a columnar structure with an arc-shaped cross section is that in practice, the author of the utility model has observed that the patient is usually in a supine position during nasogastric feeding, and the nutrient solution supply side connected to the nasogastric feeding tube is usually located on the patient's head side. Therefore, during nasogastric feeding, the contact surface between the tube body of the nasogastric feeding tube and the inner wall of the patient's nasal cavity is usually the inner top wall and the left and right inner walls of the patient's nasal cavity. Therefore, the inner arc surface of the nasal cannula 100 can effectively protect the inner wall of the patient's nasal cavity.

[0033] In addition, another reason why the inventor did not design the nasal cannula 100 into a hollow cylindrical structure is that the space in the human nasal cavity is limited. If the nasal cannula 100 is designed as a hollow cylinder, on the one hand, the nasal cavity where the gastric tube is inserted will almost completely lose its breathing function, causing the patient to breathe only through the other nostril, greatly reducing the patient's breathing quality and thus reducing his treatment experience. On the other hand, it will cause the wall design thickness of the nasal cannula 100 to decrease, thereby reducing the pressure buffering effect of the nasal cannula 100 on the nasal catheter.

[0034] It should be further explained here that, for the same reason: the part of the nasogastric tube outside the patient's body is prone to cause long-term compression to the peripheral skin of the patient's nasal cavity, so the arch pad 300 is correspondingly provided to protect the peripheral skin of the patient's nasal cavity.

[0035] In practice, the working process is as follows:

[0036] During the process of nasal feeding, one end of the nasal catheter is first inserted into the patient's nasal cavity until its opening reaches the stomach or intestine. Subsequently, the medical staff needs to measure the depth length value of the patient's nasal cavity, and based on the length value, the nasal cannula 100 of the corresponding length is cut out accordingly, and the arch pad 300, the nose wing sticker 400 and the flexible belt 200 are respectively adhered to one end of the nasal cannula 100 to make a nasal catheter fixing device. Subsequently, the nasal cannula 100 is inserted into the nasal cavity, so that the outer arc surface of the nasal cannula 100 is attached to the inner top wall and the two side walls of the patient's nasal cavity, and the tail end surface of the tube body of the nasal cannula 100 is located at the patient's nasal cavity. Subsequently, the oil paper layer on the nose wing sticker 400 is torn off, and the nose wing sticker 400 is glued and fixed to the patient's nose wing using the adhesive layer exposed on the nose wing sticker 400, so as to achieve the position fixation of the nasal cannula 100. Subsequently, the oil paper layer on one of the two flexible belts 200 is torn off, and the adhesive layer on the flexible belt 200 is used to wrap the flexible belt 200 around and stick it on the tube body portion of the nasal catheter that is retained outside the patient's body. Next, the oil paper layer on the second flexible belt 200 is torn off, and the second flexible belt 200 is wrapped around and stuck on the tube body portion of the nasal catheter that is retained outside the patient's body. Thus, the fixation of the nasal catheter by the nasal catheter fixing device is achieved. During nasogastric feeding, the tube body portion of the nasal catheter located in the patient's nasal cavity fits the outer arc surface of the nasal cannula 100, so that the nasal cannula 100 is used to block the direct contact between the tube body of the nasal catheter and the inner wall of the patient's nasal cavity, thereby reducing the pressure sores caused by the pressure of the tube body of the nasal catheter on the inner wall of the patient's nasal cavity. At the same time, the arch pad 300 is used to block the direct pressure of the tube body portion of the nasal catheter located outside the nasal cavity on the peripheral skin of the patient's nasal cavity, so as to reduce the situation of the peripheral skin of the patient's nasal cavity producing pressure sores.

[0037] The above is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they still fall within the protection scope of the present invention.
