Detailed Description
Example 1
As shown in figures 1-3, in the present embodiment, an ear hook 1 is used to fix a fixer 2 beside the ear of a patient, and a nasogastric tube is fixed beside the ear through the fixer 2, so as to fix the nasogastric tube of the patient.
In this embodiment, the ear-hook 1 is flat, and the whole ear-hook structure fits the curve of the auricle of human body, so that the ear-hook is more comfortable to wear and is difficult to feel uncomfortable after being worn for a long time.
A fixed shaft 22 of the fixer 2 is fixedly connected with the lower end of the ear-hook 1, a pair of fixed arms 21 which are arranged in a mirror symmetry mode are arranged on the shaft of the fixed shaft 22 in a matching mode through a shaft hole, the part, higher than the fixed shaft hole 213, of the fixed arm 2 is a fixed arm upper end 211, and the part, lower than the fixed shaft hole 213, of the fixed arm 2 is a fixed arm lower end 212; a groove is arranged on the inner side surface of the upper end 211 of the fixing arm, two ends of the spring 23 are respectively and fixedly arranged in the grooves of the two fixing arms 21, and the spring 23 is in a compressed state.
As shown in fig. 2 and 3, a semicircular fixing groove is formed on the lower end 212 of the fixing arm, and the two semicircular fixing grooves are oppositely arranged to form a fixing clip 214; the inside diameter of the retaining clip 214 matches the outside diameter of a nasogastric tube that can be placed inside the retaining clip 214 and clamped by the retaining clip 214 under the urging of the spring 23.
When the ear hook is used, the ear hook 1 is firstly hung on the ear of a patient, and then a nasogastric tube is inserted into the patient; after the nasogastric tube is inserted, the upper end 211 of the fixing arm is kneaded by hands, so that the lower end 212 of the fixing arm is opened, the fixing clamp 214 is opened, then the nasogastric tube passes through a through opening opened by the fixing clamp 214, after the length is adjusted, the upper end 211 of the fixing arm is loosened, the upper end 211 of the fixing arm is opened again under the action of the spring 23, so that the lower end 212 of the fixing arm is closed, the nasogastric tube is clamped, and the nasogastric tube is fixed; when the nasogastric tube needs to be removed, the fixing clip 214 can be opened and the nasogastric tube can be removed by only kneading the upper end 211 of the fixing arm by hand.
Example 2
As shown in fig. 4-6, the technical solution adopted in this embodiment is not substantially different from that adopted in embodiment 1, and the main difference is that the fixing clip 214 is not disposed on the lower end 212 of the fixing arm in this embodiment, but the fixing strap 24 is disposed.
As shown in fig. 5 and 6, at the bottom end of the lower end 212 of the fixing arm, fixing bands 24 are fixedly arranged, the fixing bands 24 are fixedly connected to the bottom ends of the lower ends 212 of the two fixing arms respectively, and a through opening structure is formed by matching the lower end 212 of the fixing arm, so that a nasogastric tube can be placed in the through opening for fixing.
In practical use, after the fixator 2 is fixed on the ear of a patient through the ear hook 1, when the nasogastric tube needs to be fixed, the upper end 211 of the fixing arm is kneaded by hand, the lower end 212 of the fixing arm is opened, the fixing band 24 is unfolded, the through opening is enlarged, the nasogastric tube passes through the enlarged through opening, after the length is adjusted properly, the upper end 211 of the fixing arm is loosened, the lower end 212 of the fixing arm is closed under the action of the spring 23, and the fixing band 24 is tightened, so that the nasogastric tube is fixed; compared with the rigid structure of the fixing clip 214, the flexible fixing band 24 can prevent the nasogastric tube from being lacerated and injured by the rigid structure, and the use of the nasogastric tube is prevented from being influenced.
Example 3
As shown in fig. 7 and 8, the technical solution used in this embodiment is not substantially different from that of embodiment 1, and the main difference is that a telescopic structure is specifically added to the lower end 212 of the fixing arm in this embodiment, and includes a telescopic outer shell 215 connected to the fixing shaft hole 213, and a telescopic inner core 216 disposed inside the telescopic outer shell 215 and having a fixing clip 214 at the lower end.
As shown in fig. 8, the telescopic housing 215 and the telescopic inner core 216 are fixed inside by elastic limit protrusions, and under the condition of no external force, the telescopic housing 215 and the telescopic inner core 216 can be fixed with each other without relative sliding due to gravity or hanging of a nasogastric tube; when a user forcibly pulls the telescopic inner core 216 inwards or outwards, the elastic limiting protrusion can be elastically deformed, so that the telescopic outer shell 215 and the telescopic inner core 216 can slide relatively to achieve the telescopic effect.
The patient's physique is different, according to patient's actual need, probably needs to adjust the length of fixer 2, so adopts flexible shell 215 and flexible inner core 216 complex structure, realizes the adjustment to fixer 2 length, can be adapted to the patient of more sizes with one and use.
Example 4
As shown in fig. 9, the present embodiment is not substantially different from the technical solution used in embodiment 3, and the main difference is that the present embodiment uses a retractable fixing arm 21 structure, and uses a fixing structure of a fixing band 24 instead of a fixing clip 214, so as to achieve the effect of protecting the nasogastric tube from being damaged.
Example 5
As shown in fig. 10-12, the present embodiment is not substantially different from the above embodiment 3 in terms of the technical solutions, but mainly different from the above embodiment in that the present embodiment uses a rotatable fixing shaft 22 structure, so that the fixer 2 can rotate horizontally and circularly, and can be adapted to use in more angles, and the practicability is stronger.
As shown in fig. 11 and 12, in the present embodiment, a rotation limiting table 221 is provided on the outer side of the fixed shaft 22, a fixed shaft seat 25 engaged with the fixed shaft 22 is provided on the outer side of the fixed shaft 22, a rotation limiting groove 251 engaged with the rotation limiting table 221 is provided on the inner side of the fixed shaft seat 25, and the fixed shaft 22 can rotate by the engagement of the rotation limiting table 221 and the rotation limiting groove 251, and drives other components provided on the fixed shaft to rotate synchronously.
In actual use, can be because the patient lies or sit the difference of standing etc. health position, the angle that the nasogastric tube is fixed need be adjusted sometimes, owing to used rotatable fixed axle 22 structure in this embodiment, so can the adaptability adjust the fixed angle of nasogastric tube to avoided because the fixed angle of nasogastric tube dies and make the inconvenient problem of patient's use.
Example 6
As shown in fig. 13, the present embodiment is not substantially different from the above embodiment 5 in terms of the technical solution, and the main difference is that in the present embodiment, while the structure of the rotatable fixed shaft 22 is used, the structure of the fixing band 24 more suitable for protecting the nasogastric tube is used.
The above-mentioned detailed description of the present invention is only for the purpose of describing specific embodiments, and not for the purpose of limiting the present invention, and any modifications or alternatives that can be easily conceived by those skilled in the art within the scope of the present invention are intended to be covered by the scope of the present invention.
