Description

Technical Field

[0001] The utility model relates to the technical field of gastric tube fixation, in particular to a gastric tube neck fixator with an anti - detachment warning function. Background Technique

[0002] The gastric tube is usually inserted through the nostril, passing through the pharynx and esophagus to reach the stomach, providing necessary nutritional support or treatment means for patients. However, during the use of the gastric tube, how to ensure the safe fixation of the gastric tube and prevent it from slipping out is a common concern for medical staff and patients. The traditional gastric tube fixation method mostly uses the adhesive tape fixation method, that is, the gastric tube is surrounded by adhesive tape at the nostril and cross - fixed to the alar part of the nose, and then a slipknot is tied around the patient's head through a cloth belt to strengthen the fixation.

[0003] However, this method has many drawbacks. For example, there is more oil and sweat gland secretion at the alar part of the patient's nose, which is likely to cause the adhesive tape to be fixed insecurely. When the loose gastric tube needs to be re - inserted by the nursing staff, the repeated process of inserting the gastric tube will bring great pain to the patient and is also likely to cause damage to the nasal mucosa, increasing the workload of nurses.

[0004] To solve the above problems, there are various improved gastric tube fixators on the market, such as wearable gastric tube fixators, but none of them can detect and monitor the risk of the gastric tube slipping out and send out a warning signal to remind medical staff to take timely measures, so as to effectively avoid the occurrence of the gastric tube slipping out.

Specific embodiments

[0024] An embodiment of the present utility model provides a gastric tube neck fixator with an anti - detachment warning function. As Figures 1-4 shown, it includes a headband 11, an extension band 12, a mounting seat 14, a warning box 16, a warning component, an elastic rope 17 and an elastic restraint band 18. The headband 11 is set to be arc - shaped. The extension band 12 is detachably arranged on the headband 11. The extension band 12 is located at the center of the upper end of the headband 11. An adjustment sliding groove 13 is formed inside the extension band 12. The mounting seat 14 is arranged in the adjustment sliding groove 13. A mounting notch 15 is formed inside the mounting seat 14, and the mounting notch 15 is used for assembling with the gastric tube.

[0025] The warning box 16 is fixedly arranged at both ends of the headband 11 along the arc length direction. The warning component is arranged on the warning box 16. The warning component includes a wire post 21, a pull rope 22, an identification element 23 and a buzzer unit 26. The elastic rope 17 is fixedly arranged at the lower end of the warning box 16. The elastic ropes 17 are arranged in an array along the length direction of the warning box 16. The elastic restraint band 18 is fixedly arranged between the two side elastic ropes 17.

[0026] Both the elastic rope 17 and the elastic restraint band 18 are made of elastic materials.

[0027] As Figure 2 shown, the mounting seat 14 includes a round shaft part located inside the adjustment sliding groove 13 and anti - detachment parts arranged on both axial sides of the round shaft part. The anti - detachment parts of the mounting seat 14 are used to prevent the round shaft part of the mounting seat 14 from falling off while sliding in the adjustment sliding groove 13. The mounting notch 15 penetrates through the mounting seat 14.

[0028] The caregiver moves the mounting base 14 along the adjustment chute 13 to position the mounting base 14 at a location and angle suitable for the installation of the gastric tube. The gastric tube is passed through the mounting slot 15 and then through the nasal cavity and esophagus for connection. An assembly ring and a sealing ring are provided on the inner wall of the mounting slot 15. Both the assembly ring and the sealing ring have the same structure as the prior art and are used to prevent the gastric tube from falling out of the mounting slot 15, thereby completing the insertion of the gastric tube and the fixation of its neck, and avoiding using wide adhesive tape to stick the gastric tube to the patient's skin, which may cause secondary infection.

[0029] As Figure 3 shown, an inner cavity 20 is provided inside the warning box 16, and a wire passing hole 25 communicating with the inner cavity 20 is opened in the warning box 16.

[0030] As Figure 3 、 Figure 4 shown, there are two sets of wire columns 21, and both are rotatably connected to the inner cavity 20. A torsion spring 24 is provided between the wire column 21 and the inner wall of the inner cavity 20. The pull rope 22 is wound around the wire column 21. One end of the pull rope 22 is fixedly arranged on the outer cylindrical surface of the wire column 21 through the identification element 23, and the other end of the pull rope 22 passes through the wire passing hole 25 and is fixedly connected to the elastic restraint band 18.

[0031] In the initial state, the torsion spring 24 keeps the pull rope 22 in a retracted state. When the pull rope 22 is subjected to a pulling force, the pull rope 22 drives the wire column 21 to rotate and twists the torsion spring 24.

[0032] The buzzer units 26 are fixedly arranged on the front and rear sides of the warning box 16. The buzzer unit 26 on the front side is electrically connected to the identification element 23 on the front side, and the buzzer unit 26 on the rear side is electrically connected to the identification element 23 on the rear side. The identification element 23 and the buzzer unit 26 have the same structure as the prior art. The identification element 23 converts the received pulling force signal into an electrical signal and transmits it to the buzzer unit 26. After the buzzer unit 26 recognizes that the electrical signal sent by the identification element 23 has changed, it emits a sound signal through its own oscillation structure, thereby emitting a prompt sound to the patient or the caregiver.

[0033] The elastic force of the elastic restraint band 18 is greater than the elastic forces of the elastic rope 17 and the torsion spring 24. When the caregiver wears the headband 11 and the elastic restraint band 18 on the patient's head, first the headband 11 is sleeved on the top of the burn patient's head, then the elastic restraint band 18 is stretched to fit the patient's mandible, and the elastic rope 17 and the pull rope 22 are made to bypass the outer contour of the patient's ear to prevent the binding band from pressing on the patient's ear and causing discomfort. At this time, the pull rope 22 is pulled to the limit state.

[0034] Since the headband 11, the warning box 16, and the elastic restraint band 18 need to adapt to the patient's head shape, they cannot be in the same plane. When the headband 11 or the elastic restraint band 18 that has been properly worn by the patient is offset, due to its own elasticity, it will become loose from the patient's head. At this time, since the extension band 12, the mounting seat 14, and the gastric tube are in an unfixed state, they are very likely to become detached from the patient's esophagus. It is necessary to remind the caregiver to re-fix the headband 11 and the elastic restraint band 18. At this time, the pull rope 22 on the offset side or both pull ropes 22 on both sides are wound by the wire post 21 under the elastic force of the torsion spring 24, resulting in the pulling force on the recognition element 23 being reduced to zero. After the buzzer unit 26 recognizes that the electrical signal emitted by the recognition element 23 has changed, it emits an acoustic signal, thereby emitting a prompt sound to the patient or the caregiver, reminding the caregiver to re-fix the headband 11 and the elastic restraint band 18 to prevent the gastric tube from becoming detached from the patient's esophagus.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
