Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully and specifically with reference to the accompanying drawings and preferred embodiments, but the scope of the present invention is not limited to the following specific embodiments.

Example (b):

as shown in fig. 1 and 2, the gastric tube fixator of the embodiment comprises a copying nose mask 1 matched with the shape of the nose, fixing bands 2 used for being tied on the head of a patient are arranged on two side edges of the copying nose mask 1, the copying nose mask 1 can be well attached to the nose structure, stress is uniformly transmitted to the skin of the nose, damage to the skin and the internal structure of the nose is avoided, and comfort level in the using process is improved. An air vent 11 and a cannula hole 12 that is used for pegging graft stomach tube 3 are seted up with nostril position department of correspondence on the profile modeling nose cup 1, the outside of profile modeling nose cup 1 still is equipped with the periphery that is located cannula hole 12 and is used for preventing the locking mechanical system 4 that stomach tube 3 drops, locking mechanical system 4 is fixed through the stomach tube 3 of cannula hole 12, improve the stability of stomach tube 3, effectively reduce the possibility that 3 atresss of stomach tube drop, avoid relapseing the intubate, with the result of use that influences stomach tube 3. The locking mechanism 4 is connected to the outer side of the profiling nose mask 1, so that interference with nasal structures such as nostrils of a patient is avoided, the overall structure of the profiling nose mask 1 can be simplified, and the patient can conveniently carry and use the profiling nose mask.

In this embodiment, the locking mechanism 4 comprises at least a pair of clamping straps 41, each clamping strap 41 being disposed on the contoured mask 1 at the periphery of the cannula bore 12 and symmetrically disposed with respect to the cannula bore 12 to provide a uniform and stable clamping force. The end of at least one of the clamping hoops 41 is provided with a driving assembly 42 for driving the clamping hoop 41 to move towards the other clamping hoops 41 so as to clamp the gastric tube 3, and the driving assembly 42 is arranged outside the profiling nasal mask 1. The clamping side of the clamping hoop 41 is provided with an arc section matched with the shape of the gastric tube 3, and the arc sections of the clamping hoops 41 are butted to form an avoiding hole 43 with the diameter smaller than that of the gastric tube 3.

After stomach tube 3 inserts in the cannula hole 12, drive assembly 42 drives each centre gripping hoop 41 closed formation and dodges hole 43, because the diameter of dodging hole 43 is less than stomach tube 3 diameter, consequently can ensure when providing clamping-force for stomach tube 3, avoids excessively extrudeing stomach tube 3 to lead to the fact the result that is difficult to realize stomach tube 3 function.

In this embodiment, be equipped with the elasticity cushion 44 on the segmental arc side of centre gripping hoop 41, further prevent that centre gripping hoop 41 from causing extrusion deformation to stomach tube 3, improve the result of use. Be equipped with anti-skidding stripe 441 on the elastic cushion 44, the direction of anti-skidding stripe 441 and the axial nonparallel of dodging hole 43, promptly with stomach tube 3 under the situation of deviating from, the direction of stress has certain contained angle, is the vertical state even, improves stomach tube 3's fixed state stability, effectively reduces the possibility that stomach tube 3 deviates from.

In this embodiment, as shown in fig. 3, the driving assembly 42 includes a guiding shell 421 and an elastic member 422, the guiding shell 421 is provided with an opening for accommodating the end of the clamping hoop 41, and two sides of the opening are provided with limiting strips located at two sides of the clamping hoop 41 to guide the movement of the clamping hoop 41, so as to avoid the difficulty in realizing the clamping function due to the direction deviation in the moving process. The end of the clamping hoop 41 is supported and connected with the inner wall of the guide shell 421 through the elastic piece 422, the elastic piece 422 enables the clamping hoop 41 to keep closed to firmly clamp and fix the gastric tube 3 in a normal state, and when the gastric tube needs to be detached, the clamping hoop 41 is manually pressed or pushed, so that the intubation hole 12 can be opened, and the gastric tube 3 can be released. The driving assembly 42 of the present embodiment has a simple structure and is convenient and fast to operate. In other embodiments, a micro hydraulic driving device or an electric driving device may also be used, which is not described herein.

In this embodiment, the hydrocolloid layer is attached to the inner side of the profiling nose mask 1, and when the hydrocolloid layer is in contact with the skin, the hydrocolloid layer can effectively reduce the injury caused by friction, and improve the use feeling of a patient.

In this embodiment, the length adjustment buckle 21 is disposed on the fixing band 2 to adjust the length of the fixing band 2, so as to adapt to different patients. The length adjusting buckle 21 is close to one side of the profiling nose mask 1, so that the influence on the lateral lying of the patient is avoided.

The above description is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. For those skilled in the art, the modifications and changes obtained without departing from the technical idea of the present invention should be regarded as the protection scope of the present invention.
