Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a nasogastric feeding tube. Background Technology

[0002] A gastric tube is used in special circumstances to deliver necessary fluids and food to patients who cannot swallow. Gastric tubes are generally made of polyurethane or silicone; depending on the material, polyurethane and silicone tubes should be replaced monthly. They come in various sizes and lengths and can be divided into oropharyngeal tubes and nasogastric tubes. Nasogastric tubes are approximately 105cm long and are inserted about 55cm through the nostril, passing through the pharynx, esophagus, and stomach. Nasogastric tubes are prone to dislodgement and require securing to prevent repeated intubation and aspiration. The common method of securing a gastric tube is to use adhesive tape to attach it to the patient's nostril.

[0003] If adhesive tape is left on the face for a long time, it will leave adhesive residue that is difficult to clean and affects the appearance. The area where it is applied is also very likely to cause skin allergies. Utility Model Content

[0004] This invention provides a nasogastric tube to address the shortcomings of existing technologies where the tube is fixed with adhesive tape, which can easily affect the patient's skin.

[0005] This utility model provides a nasogastric feeding tube, comprising:

[0006] The gastric tube body includes a first tube and a second tube connected together. The first tube is used to be inserted into the patient's body through the patient's nostril, and the second tube is located outside the patient's body.

[0007] A plastic deformation sleeve is fitted onto the second tube body. The plastic deformation sleeve can be bent and deformed according to the shape of the patient's ear so that it can be attached to the patient's ear.

[0008] According to the nasogastric tube of this utility model, the plastic deformation sleeve includes a first sleeve and a second sleeve that are spaced apart along the length direction of the tube body.

[0009] The first sleeve is fitted onto the second tube, and the first sleeve is used to attach to the patient's ear after deformation;

[0010] The second sleeve is disposed between the first tube and the first sleeve, and the first sleeve is used to bend according to the shape of the patient's face so as to fit the patient's face.

[0011] According to the nasogastric tube of this utility model, the plastic deformation sleeve includes a plastic deformation layer and a flexible layer, the plastic deformation layer is sleeved on the second tube body; the flexible layer covers the plastic deformation layer.

[0012] According to the nasogastric tube of this utility model, the plastic deformation layer is a tubular metal support layer, and the second tube body is inserted through the tubular metal support layer.

[0013] According to the nasogastric tube of this invention, the flexible layer is a silicone layer.

[0014] The nasogastric tube according to this utility model also includes a flexible pad, which is disposed on the outer peripheral wall of the plastic deformation sleeve. When the plastic deformation sleeve is attached to the patient's ear, the flexible pad is used to contact the patient's ear skin.

[0015] According to the nasogastric tube of this utility model, the flexible pad includes a first pad and a second pad that are spaced apart along the length direction of the tube body.

[0016] When the plastic deformation sleeve is attached to the patient's ear, the first pad is used to contact the skin at the top of the ear, and the second pad is used to contact the skin behind the ear.

[0017] According to the nasogastric tube of this utility model, the first pad includes a first arc-shaped part, a contact part, and a second arc-shaped part connected in sequence.

[0018] When the plastic deformation sleeve is straight, the contact portion is planar on the side away from the plastic deformation sleeve; the first arc-shaped portion is arc-shaped on the side away from the plastic deformation sleeve, and extends from the contact portion away from the plastic deformation sleeve to the outer peripheral wall of the plastic deformation sleeve; the second arc-shaped portion is arc-shaped on the side away from the plastic deformation sleeve, and extends from the other end of the contact portion away from the plastic deformation sleeve to the outer peripheral wall of the plastic deformation sleeve.

[0020] This invention relates to a nasogastric feeding tube. The first tube body is inserted into the patient's stomach through the nostril, while the second tube body remains outside the patient's body and connects to external water and food supply equipment for delivering fluids and food. Simultaneously, a deformable sleeve is fitted onto the second tube body, allowing medical personnel to manually bend the sleeve according to the shape of the patient's ear. This keeps both the sleeve and the second tube body in a bent position, allowing them to suspend from the patient's ear, thus preventing the nasogastric tube from detaching from the patient's face. It also eliminates the need for adhesive tape to fix the nasogastric tube to the patient's nostrils, effectively solving the problem of existing technologies where adhesive tape fixation of the feeding tube can easily irritate the patient's skin.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only one embodiment of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] The following is combined with Figures 1-2 This invention describes the nasogastric feeding tube.

[0031] like Figure 1 As shown, this utility model provides a nasogastric tube 1, including a tube body 11 and a deformable sleeve 12. The tube body 11 includes a first tube 111 and a second tube 112 connected together. The first tube 111 is inserted into the patient's body through the nostril, and the second tube 112 is located outside the patient's body. The deformable sleeve 12 is fitted onto the second tube 112. The deformable sleeve 12 can be bent and deformed according to the shape of the patient's ear so as to be attached to the patient's ear.

[0032] In this embodiment, the gastric tube body 11 is divided into a first tube 111 and a second tube 112. The first tube 111 is used to extend into the patient's body through the nostril and enter the stomach through the pharynx and esophagus. The second tube 112 remains outside the patient's body so as to connect with external water and food supply equipment to deliver necessary water or food to the patient.

[0033] Meanwhile, the second tube 112 is fitted with a plastic deformation sleeve 12, which can plastically deform under external force to adjust the curvature of itself and the second tube 112. Medical staff can adjust the curvature of the plastic deformation sleeve 12 and the second tube 112 according to the shape of the patient's ear, so that this part of the plastic deformation sleeve 12 and the second tube 112 can be suspended from the patient's ear, thereby fixing the second tube 112 and preventing the nasogastric tube 1 from detaching from the patient's face. There is no need to use tape to stick the nasogastric tube 1 to the patient's nasal ala.

[0034] The nasogastric tube 1 of this invention involves inserting the first tube 111 of the tube body 11 into the patient's stomach through the nostril, while the second tube 112 remains outside the patient's body and is connected to external water and food supply equipment to deliver water and food to the patient. Simultaneously, by fitting a plastic deformation sleeve 12 onto the second tube 112, medical personnel can manually bend the sleeve 12 according to the shape of the patient's ear, keeping both the sleeve 12 and the second tube 112 in a bent state for suspension around the patient's ear. This prevents the nasogastric tube 1 from detaching from the patient's face and eliminates the need for adhesive tape to fix the tube to the patient's nostrils, effectively solving the problem of adhesive tape fixation of gastric tubes in existing technologies, which can easily affect the patient's skin.

[0035] Understandable, Figure 1 Only a portion of the first tube 111 is shown in the image; the actual length of the first tube 111 needs to be adjusted according to the patient's condition.

[0036] In some embodiments, such as Figure 1 As shown, the plastic deformable sleeve 12 includes a first sleeve 121 and a second sleeve 122 spaced apart along the length of the gastric tube body 11. The first sleeve 121 is fitted onto the second tube body 112 and is used to attach to the patient's ear after deformation. The second sleeve 122 is disposed between the first tube body 111 and the first sleeve 121, and the first sleeve 121 is used to bend according to the shape of the patient's face so as to fit the patient's face.

[0037] In this embodiment, the first sleeve 121 is located on the second tube 112 at a position relatively far from the first tube 111. The first sleeve 121 is designed to correspond to the patient's ear and to bend under external force, so that the curvature of the first sleeve 121 and the corresponding part of the second tube 112 is similar to the curvature of the connection between the patient's auricle and face, thereby allowing it to hang on the patient's auricle. The second sleeve 122 is located between the first sleeve 121 and the first tube 111 and is designed to bend under external force. The shape of the first sleeve 121 and the corresponding part of the second tube 112 is similar to the facial contour near the patient's nostrils, so that the second tube 112 near the patient's nostrils can better fit the patient's face, and the entire second tube 112 can better fit the patient's face.

[0038] In some embodiments, such as Figure 2 As shown, the plastic deformation sleeve 12 includes a plastic deformation layer 123 and a flexible layer 124. The plastic deformation layer 123 is sleeved on the second tube body 112. The flexible layer 124 covers the plastic deformation layer 123.

[0039] In this embodiment, the plastic deformation sleeve 12 includes a plastic deformation layer 123 and a flexible layer 124 stacked together. The plastic deformation layer 123 is located in the inner layer and is directly sleeved on the second tube 112. The flexible layer 124 covers the outer side of the plastic deformation layer 123. The plastic deformation layer 123 can undergo plastic deformation under the action of external force to change the posture of the flexible layer 124 and the second tube 112 inside it so as to conform to the patient's skin. The flexible layer 124 is used to contact the patient's skin. The flexible layer 124 is softer and has a better feel, which can effectively reduce the pressure and wear on the patient's skin when in contact with the patient's skin.

[0040] Specifically, in some embodiments, such as Figure 2 As shown, the plastic deformation layer 123 is a tubular metal support layer, and the second tube 112 is inserted through the tubular metal support layer.

[0041] In this embodiment, a hole is formed in the middle of the tubular metal stent layer to allow the second tube 112 to be inserted. The tubular metal stent layer can bend and deform under external force and can maintain its deformed posture well, so that the second tube 112 and the plastic deformation sleeve 12 can always fit the patient's skin during long-term use, preventing the second tube 112 from falling off the patient's face.

[0042] Specifically, in some embodiments, the wall of the tubular metal support layer can be a mesh-like wall woven from metal wires, which helps to reduce the thickness of the entire tubular metal support layer and makes the structure of the plastic deformation layer 123 and the second tube 112 lighter and more compact.

[0043] Specifically, in some embodiments, the flexible layer 124 is a silicone layer. The silicone layer is smooth and soft, has a good tactile feel, is not prone to rejection, poses no harm to the human body, has good biocompatibility, possesses excellent medical properties, is colorless, non-toxic, heat-resistant, oxidation-resistant, and highly flexible and transparent. Furthermore, the silicone sleeve is easy to clean; users can maintain the cleanliness of the silicone layer through simple washing or wiping, thereby better maintaining the cleanliness of the flexible layer 124.

[0044] In some embodiments, such as Figure 1 As shown, the nasogastric tube 1 also includes a flexible pad 13, which is disposed on the outer peripheral wall of the plastic deformation sleeve 12. When the plastic deformation sleeve 12 is attached to the patient's ear, the flexible pad 13 is used to contact the patient's ear skin.

[0045] In this embodiment, by providing a flexible pad 13 on the outer peripheral wall of the plastic deformation sleeve 12, when the plastic deformation sleeve 12 is bent and hung on the patient's ear, the flexible pad 13 can contact the patient's ear skin, increase the contact area, reduce the pressure on the ear skin, so as to protect the patient's ear skin during long-term use.

[0046] Specifically, in some embodiments, such as Figure 1 As shown, the flexible pad 13 includes a first pad 131 and a second pad 132 spaced apart along the length of the gastric tube body 11. When the plastic deformation sleeve 12 is attached to the patient's ear, the first pad 131 is used to contact the skin at the top of the ear, and the second pad 132 is used to contact the skin behind the ear.

[0047] In this embodiment, a first pad 131 and a second pad 132 are spaced apart along the length of the gastric tube body 11. The first pad 131 corresponds to the top of the auricle so that it contacts the skin at the top of the ear when the plastic deformation sleeve 12 is attached to the patient's ear. The second pad 132 corresponds to the posterior part of the auricle so that it contacts the skin behind the ear. This increases the contact area between the flexible pad 13 and the patient's skin when the plastic deformation sleeve 12 is attached to the patient's ear, allowing the entire second tube body 112 to be better fixed to the patient's ear and reducing the pressure of the plastic deformation sleeve 12 on the ear. Furthermore, by spaced the first pad 131 and the second pad 132 apart, they are prevented from being damaged by pulling on each other when the plastic deformation sleeve 12 is bent. The structure is simple, convenient, and practical.

[0048] Specifically, in some embodiments, such as Figure 1As shown, the first gasket 131 includes a first arcuate portion 1311, a contact portion 1312, and a second arcuate portion 1313 connected in sequence. When the plastic deformation sleeve 12 is straight, the contact portion 1312 is planar on the side facing away from the plastic deformation sleeve 12. The first arcuate portion 1311 has an arcuate surface on the side facing away from the plastic deformation sleeve 12, and extends from the contact portion 1312 away from the plastic deformation sleeve 12 to the outer peripheral wall of the plastic deformation sleeve 12. The second arcuate portion 1313 has an arcuate surface on the side facing away from the plastic deformation sleeve 12, and extends from the other end of the contact portion 1312 away from the plastic deformation sleeve 12 to the outer peripheral wall of the plastic deformation sleeve 12.

[0049] In this embodiment, the contact portion 1312 of the first pad 131 is the main structure for contact between the first pad 131 and the patient's ear. The first arc-shaped portion 1311 and the second arc-shaped portion 1313 are respectively connected to the two ends of the contact portion 1312, serving as a transition structure between the contact portion 1312 and the outer peripheral wall of the plastic deformation sleeve 12. This allows the outer side of the contact portion 1312 to transition to the outer peripheral wall of the plastic deformation sleeve 12 through the arc-shaped surfaces of the first arc-shaped portion 1311 and the second arc-shaped portion 1313. As a result, the contact surface between the first pad 131 and the patient's ear has no sharp structure, which is beneficial for protecting the patient's skin.

[0050] Specifically, in some embodiments, the flexible pad 13 is a silicone pad. The silicone pad is elastic and can deform with the plastic deformation sleeve 12. At the same time, it is relatively soft, has a good feel, will not cause harm to the human body, has good biocompatibility, and is easy to clean.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to the tube body technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
