In order to achieve the purpose, the invention adopts the following technical scheme:
a stomach tube fixer for nasal cavity is characterized in that: the stomach tube elastic plate comprises an elastic plate, wherein the elastic plate extends around the circumference of the stomach tube and forms a C-shaped plate shape, and the middle section of the inner wall of the elastic plate and the outer wall of the stomach tube are connected with each other through a radial connecting column; the fixator further comprises a threaded sleeve coaxially fixed on the outer wall of the stomach tube, the tail end of the traction rope is fixed on the elastic plate, a space is reserved between the fixing point and the radial connecting column, a compression ring is matched with coaxial threads on the threaded sleeve, a passing cavity into which the traction rope can extend is formed between the compression ring and the outer wall of the stomach tube, and the head end of the traction rope axially extends into the passing cavity along the stomach tube and is fixedly connected and matched with the threaded sleeve; in the radial direction of the compression ring, the thickness of the passing cavity is smaller than the radial distance between the tail end of the traction rope and the outer wall of the stomach tube.
Preferably, the fixed sleeve and the threaded sleeve are coaxially arranged in sequence from inside to outside along the radial direction of the gastric tube, the fixed sleeve and the threaded sleeve form an integrated structure, and the fixed sleeve is detachably fixed on the outer wall of the gastric tube through a set screw or a half joint.
Preferably, the axis of the radial connecting column forms an included angle with the axis of the fixed sleeve, and the tip of the included angle points to the direction of the threaded sleeve.
Preferably, the end that closes on the thread bush with the elastic plate is the front end, and the elastic plate appearance is the frustum form plate body structure that the front end aperture is greater than the rear end aperture, and the haulage rope tail end is fixed on the intrados of elastic plate.
Preferably, the inner wall of the pressure ring is provided with a wear-resistant layer in the shape of a bearing bush.
Preferably, the outer wall of the pressing ring is provided with anti-skid grains convenient to operate.
Preferably, the cantilever end of the elastic plate is provided with an inward-winding arc-shaped inward flange.
Preferably, the outer arc surface of the elastic plate and the two cantilever ends are both provided with soft cushion layers.
The invention has the beneficial effects that:
1) the medical adhesive plaster is different from the traditional medical adhesive plaster pasting structure, and the elastic restoring force of the C-shaped elastic plate is utilized, so that the function of tightly propping and fixing the nasal cavity of a patient from inside to outside is realized. During specific operation, the compression ring can change the compression length of the traction rope by adjusting the axial action of the compression ring relative to the thread sleeve, and accordingly indirect control over the bending degree of the elastic plate is achieved. When the elastic plate is bent to a large degree, the stomach tube can be easily separated from the nasal cavity of a patient; thereby and relax the haulage rope when adjusting the clamping ring, can make the elastic plate reduce gradually in self elastic restoring force effect down bending degree, the elastic plate that is located patient's nasal cavity plays the effect of propping up patient's nasal cavity gradually.
Obviously, by the scheme, on one hand, the fixation of the gastric tube relative to the nose of the patient is not influenced by the skin property of the patient any more, and the fixation is reliable and stable; on the other hand, the elastic plate is reset or retracted, namely the action of the elastic plate is controllable, the gastric tube can be taken down and fixed on the nasal cavity of a patient at any time, and the use flexibility can be obviously improved.
In conclusion, the nose fixing device has the advantages of being flexible and convenient to operate, capable of achieving the reliable fixing function relative to the nose of a patient and beneficial to clinical use.
2) In practical use, the thread sleeve and the like can be directly and integrally molded on the stomach tube, so that the stomach tube with a corresponding structure can be directly manufactured. In order to further improve the application range of the invention, the threaded sleeve and the elastic plate with the radial connecting column are uniformly integrated on the fixed sleeve, and only the fixed sleeve with the threaded sleeve and the elastic plate needs to be produced during production; when in use, the fixing sleeve is fixed on the corresponding purchased existing stomach tube, so that the production cost is lower, the operation is more flexible and changeable, and the use in the existing large environment is facilitated.
3) Furthermore, in order to ensure the flexible response effect of the inward contraction and tightening actions of the elastic plate, on one hand, the radial connecting columns are arranged to be oblique rods, so that the stress performance of the elastic plate is improved; on the other hand forms the frustum of a cone structure with the elastic plate body, and this makes in case the elastic plate receives the pulling force of the haulage rope inwards forward, and the elastic plate can realize the effect of contracting in rapidly, and in case the pulling force of haulage rope is eliminated, the elastic plate also can reset under self elastic force rapidly to fix the reliable tight support of stomach tube in patient's nasal cavity.
4) Certainly, the elastic plate needs to be fixed at the nasal cavity of a patient by virtue of elastic restoring force, so that the arc-shaped inward flanging can effectively avoid the damage of two suspension ends of the elastic plate to the sensitive nasal cavity; meanwhile, the soft cushion layer is matched, so that the clinical comfort of the patient can be effectively improved.

Detailed Description
For the purposes of understanding, the invention will be further described in its specific structure and mode of operation with reference to the accompanying drawings in which:
the main structure of the invention is shown in fig. 1-3, and comprises a threaded sleeve 20, a press ring 40, a traction rope 30 and a springboard 10 with a radial connecting column 11 which are sequentially arranged from front to back along the axial direction of a gastric tube a. Wherein:
when the present invention is constructed as shown in fig. 1-2, the threaded hub 20, the compression ring 40 and the gastric tube a are coaxial with each other, and the threaded hub 20 and the gastric tube a are formed as a single structure, i.e., the threaded hub 20 and the gastric tube a are integrally formed at the beginning of the design. The radial connecting column 11 is fixed on the outer wall of the gastric tube a in the same way, so that when the elastic plate 10 is pulled by the pulling rope 30, the radial connecting column 11 can play a role of an anchoring point to limit the elastic plate 10 from generating axial overall displacement. As can be seen in fig. 1, the pressure ring 40 serves as an adjusting ring, which on the one hand is screwed onto the external thread section at the rear end of the threaded sleeve 20; on the other hand, the pull string 30 must pass through the annular cavity of the compression ring 40 as shown in fig. 2 before being fixed to the rear end surface of the threaded sleeve 20. Since the radial distance from the fixing point of the pulling rope 30 and the elastic plate 10 to the outer wall of the gastric tube a is obviously larger than the radial distance from the annular cavity of the pressing ring 40 to the outer wall of the gastric tube a, once the pressing ring 40 rotates along the threaded sleeve 20 and generates the axial action towards the right, namely, backwards, as shown in fig. 2, the pulling rope 30 is pressed downwards, and then the elastic plate 10 generates the inward-retracting action. And once the pressure spring rotates along the thread bush 20 and generates a leftward movement along the gastric tube a, namely, a forward movement, the restraint of the traction rope 30 is released, the elastic plate 10 is reset under the action of the self elastic restoring force, the nasal cavity of the patient can be tightly supported again, and the use is very flexible and convenient.
In practice, the pulling rope 30 can be formed directly by plastic strips, and does not necessarily have to be a rope structure. The pressing and loosening effects on the pulling rope 30 can be achieved by rotating the pressing ring 40 during operation. The anti-slip pattern 41 is designed to increase the handling feeling. And will not be described in detail herein.
Fig. 3 is a further preferred embodiment of the present invention, which aims to form an add-on assembly as an accessory for the conventional gastric tube a currently on the market. Specifically, the aforementioned compression ring 40, threaded sleeve 20 and elastic plate 10 are integrally mounted on the fixing sleeve 50, and the fixing sleeve 50 is fixed on the gastric tube a by a set screw or other conventional detachable structure as shown in fig. 3. Therefore, only the fixing sleeve 50 with the thread sleeve 20 and the elastic plate 10 needs to be manufactured during production and manufacturing, and the fixing sleeve 50 is fixed on the corresponding purchased existing stomach tube a during use, so that the production cost is lower, the operation is more flexible and changeable, and the use in the current large environment is facilitated.
