[0003] As disclosed in the Chinese utility model patent with the authorization publication number CN204501825U and the authorization publication date of July 29, 2015, a gastrointestinal decompression device for the digestive department specifically includes an absorption bottle. The top of the absorption bottle is communicated with a suction cylinder through a hose. A dense fiber filter screen is provided at the mouth edge of the absorption bottle. A gastric tube is connected to the side of the absorption bottle. The gastric tube is provided with a silica gel ring and silica gel sponge. The bottom of the absorption bottle is communicated with a liquid storage bottle through a lead pipe. A one-way overflow port is provided at the top of the liquid storage bottle; the suction cylinder is provided with a piston. The piston rod connected to the piston extends outside the suction cylinder. The piston is provided with an exhaust hole, and a one-way exhaust valve is provided in the exhaust hole.

[0004] The existing gastrointestinal decompression device in the prior art is provided with a silica gel ring and silica gel sponge on the gastric tube, which can effectively relieve the irritation of the gastric tube to the patient's throat and gastric mucosa. However, the contact positions of the gastric tube with the gastric wall and esophageal wall remain unchanged, which is likely to cause ulcer bleeding due to long-term contact; moreover, some patients have gastrointestinal bleeding due to the disease itself. The indwelling gastric tube cannot detect gastrointestinal bleeding in time and it is difficult to estimate and locate the bleeding site. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is that ulcer bleeding is caused by the long-term contact of the gastric tube, some patients have gastrointestinal bleeding due to the disease itself, the indwelling gastric tube cannot detect gastrointestinal bleeding in time, and it is difficult to estimate and locate the bleeding site.

[0006] In order to solve the above technical problems, the utility model provides an indwelling gastric tube that reduces wall adhesion damage and prompts the bleeding site:

[0007] The indwelling gastric tube that reduces wall adhesion damage and prompts the bleeding site includes a gastric tube body and an absorbable sponge layer. One end of the gastric tube body is provided with an insertion end, and the other end of the gastric tube body is provided with an oral and nasal end. The absorbable sponge layer is coated on the outer wall of the gastric tube body;

[0008] A plurality of gastric tube side holes are opened on the tube walls of the gastric tube body and the absorbable sponge layer close to the insertion end. The gastric tube side holes are communicated with the internal space of the gastric tube body;

[0009] An indicating strip is further provided inside the absorbable sponge layer. The indicating strip is arranged in a spiral shape around the outer peripheral wall of the gastric tube body, and the indicating strip is used to show color when contacting with blood.

[0010] Further, the absorbable sponge layer is any one of a gelatin sponge layer, a collagen sponge layer, a polylactic acid sponge layer, a polyhydroxy lactic acid sponge layer, and a chitosan hydrochloride sponge layer.

[0011] Further, the thickness dimension of the absorbable sponge layer is any dimension between 2 mm and 6 mm.

[0012] Further, the pitch dimension of the indicating strip in the length direction of the gastric tube body is any dimension between 5 mm and 25 mm.

[0013] Further, the pitch dimension of the indicating strip in the length direction of the gastric tube body is any one of 8 mm, 10 mm, and 12 mm.

[0014] Further, the indicating strip is arranged in a corrugated shape or a zigzag shape along the thickness cross-section direction of the absorbable sponge layer.

[0015] Further, scale marks are further provided on the outer wall of the absorbable sponge layer. The scale marks are equally spaced along the length direction of the gastric tube body, and the scale unit of the scale marks is 5 mm or 10 mm.

[0016] Compared with the prior art, a indwelling gastric tube for reducing adherent injury and indicating bleeding site of the present utility model has the beneficial effects that: the indwelling gastric tube for reducing adherent injury and indicating bleeding site adopts a design form of a gastric tube body, an absorbable sponge layer, and an indicating strip. Among them, the absorbable sponge layer is coated on the outer wall of the gastric tube body, and the absorbable sponge layer is used to reduce the contact pressure between the indwelling gastric tube and the gastric wall or the esophageal wall. Moreover, the sponge layer in the contact part can be absorbed by the gastric wall or the esophageal wall. After being absorbed, the thickness of the sponge layer decreases, and the indwelling gastric tube displaces due to the change of the stress point, which is equivalent to changing the contact position between the indwelling gastric tube and the gastric wall or the esophageal wall, and avoiding the situations such as mucosal ulcer and bleeding that may be caused by contacting the same part for a long time.

[0017] When there is bleeding in the gastric wall or esophageal mucosa of the patient, the indicating strip at the corresponding position of the indwelling gastric tube will show color when encountering blood. According to the relative position between the color showing part of the indicating strip and the gastric tube body, the bleeding position of the gastric wall or esophageal wall can be estimated, which is convenient for timely treating the problem of digestive tract bleeding and avoiding aggravating the condition due to the failure to timely treat the digestive tract bleeding. When in use, the insertion end of the gastric tube body is inserted into the digestive tract of the patient, and drugs or fluids are injected into the patient through the oral and nasal end of the gastric tube body. The drugs or fluids enter the stomach through the side holes and the insertion end of the gastric tube, thereby achieving the purpose of disease treatment and nutrient injection.

For example, it may be a fixed connection, a detachable connection, or integrated; it may be directly connected, or indirectly connected through an intermediate medium, and may be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0026] As Figures 1 to 3 shown, a indwelling gastric tube for reducing adherent injury and prompting bleeding site in an embodiment of the present utility model includes a gastric tube body 1 and an absorbable sponge layer 2. One end of the gastric tube body 1 is provided with an insertion end 11, the other end of the gastric tube body 1 is provided with an oral and nasal end 12, and the absorbable sponge layer 2 is coated on the outer wall of the gastric tube body 1; a plurality of gastric tube side holes 10 are formed in the tube walls of the gastric tube body 1 and the absorbable sponge layer 2 close to the insertion end 11, and the gastric tube side holes 10 are communicated with the internal space of the gastric tube body 1; a color display band 3 is further arranged inside the absorbable sponge layer 2, and the color display band 3 is arranged in a spiral shape around the outer peripheral wall of the gastric tube body 1, and the color display band 3 is used for coloring when contacting with blood.

[0027] The indwelling gastric tube for reducing adherent injury and prompting bleeding site adopts the design forms of the gastric tube body 1, the absorbable sponge layer 2 and the color display band 3. Among them, the absorbable sponge layer 2 is coated on the outer wall of the gastric tube body 1, and the contact pressure between the indwelling gastric tube and the gastric wall or esophageal wall can be reduced by using the absorbable sponge layer 2. Moreover, the sponge layer in the contact part can be absorbed by the gastric wall or esophageal wall, and the thickness of the absorbed sponge layer is reduced, and displacement occurs due to the change of the stress point of the indwelling gastric tube, which is equivalent to changing the contact position between the indwelling gastric tube and the gastric wall or esophageal wall, and avoiding the situations such as mucosal ulcer and bleeding that may be caused by long-term contact with the same part.

[0028] When there is bleeding in the gastric wall and esophageal mucosa of the patient, the color display band 3 at the corresponding position of the indwelling gastric tube will show color when encountering blood. According to the relative position between the coloring part of the color display band 3 and the gastric tube body 1, the bleeding position of the gastric wall and esophageal wall can be estimated, which is convenient for timely treatment of digestive tract bleeding problems and avoiding aggravating the condition due to untimely treatment of digestive tract bleeding. When in use, the insertion end 11 of the gastric tube body 1 is extended into the digestive tract of the patient, and drugs or fluids are injected into the patient through the oral and nasal end 12 of the gastric tube body 1, and the drugs or fluids enter the stomach through the gastric tube side holes 10 and the insertion end 11, thereby achieving the purposes of disease treatment and nutrition injection.

[0029] Among them, the absorbable sponge layer 2 can be any one of a gelatin sponge layer, a collagen sponge layer, a polylactic acid sponge layer, a polyhydroxy lactic acid sponge layer, and a chitosan hydrochloride sponge layer. In this embodiment, the absorbable sponge layer 2 is made of gelatin sponge, which is a product made from hydrolyzed collagen extracted from animal skin. After drying, it forms a porous sponge structure that can be completely absorbed by human tissues and is not likely to cause immune rejection with the human body. In other embodiments, a collagen sponge layer, a polylactic acid sponge layer, a polyhydroxy lactic acid sponge layer, and a chitosan hydrochloride sponge layer can also be selected, which can also meet the requirements of buffering contact and easy absorption.

[0030] As a further preferred solution, the thickness dimension of the absorbable sponge layer 2 is any dimension between 2 mm and 6 mm. Specifically, the thickness dimension of the absorbent sponge layer 2 is 3 mm or 5 mm, which can not only effectively wrap the gastric tube body 1 to form a soft outer protective layer, but also avoid affecting the smooth intubation of the indwelling gastric tube due to excessive thickness.

[0031] The pitch dimension of the color display band 3 in the length direction of the gastric tube body 1 is any dimension between 5 mm and 25 mm. Specifically, the pitch dimension of the color display band 3 in the length direction of the gastric tube body 1 is 8 mm. When the color display bands 3 at different positions turn color when encountering blood, it indicates bleeding at the corresponding position of the digestive tract. In other embodiments, to meet different usage requirements, the pitch dimension of the color display band 3 in the length direction of the gastric tube body 1 can be designed as 5 mm, 10 mm, 12 mm, 15 mm, or 20 mm, etc., and the distribution density of the color display band 3 can be flexibly adjusted according to the actual clinical needs.

[0032] In addition, the color display band 3 is arranged in a corrugated shape or a zigzag shape along the thickness cross-section direction of the absorbable sponge layer 2, as Figure 3 shown. After the absorbable sponge layer 2 comes into contact with the gastric wall or the esophageal wall and is absorbed, the color display band 3 is exposed to the internal environment of the digestive tract and can contact the inner wall mucosa of the digestive tract, thus playing a role in accurately indicating the bleeding position.

[0033] Moreover, a scale mark 4 is provided on the outer wall of the absorbable sponge layer 2. The scale marks 4 are evenly spaced along the length direction of the gastric tube body 1, and the scale unit of the scale marks 4 is 5 mm or 10 mm. According to the scale marks 4, the position where the color display band 3 turns color when encountering blood can be intuitively judged, and thus the specific bleeding position in the digestive tract can be determined, ensuring the reliability of bleeding prompt.

[0034] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and replacements can be made, and these improvements and replacements should also be regarded as the protection scope of the present invention.
