Description

Technical Field

[0001] The invention belongs to the technical field of medical devices and relates to a stomach tube tail end fixing device. Background Art

[0002] At present, some patients in clinical practice need to inject food directly into the stomach through a gastric tube for digestion due to loss of consciousness or difficulty swallowing or eating. After the gastric tube is inserted into the patient's stomach, a section will be left outside the body to facilitate subsequent nutrient solution injections, etc. In order to prevent the gastric tube left outside the body from shifting or falling out, it is generally necessary to use an auxiliary structure to fix the tail end of the gastric tube (i.e., the end of the gastric tube left outside the body). The existing fixing method generally uses gauze to tie and wrap the tail end of the gastric tube. Then, this fixing method has a poor fixing effect. In addition, when the patient has a small or small flow reflux, since the tail end of the gastric tube is completely wrapped with gauze, and some patients may not have obvious discomfort symptoms, such as choking, dyspnea, etc. Especially for some patients who are unconscious or have limited ability to express themselves, they are unable to accurately tell medical staff about their physical discomfort. In addition, the hospital ward environment is complex, and medical staff need to take care of multiple patients at the same time. They are busy with work and may not be able to always focus on the gastric tube condition of a particular patient. This makes it difficult for medical staff to discover small-volume reflux through the patient's subjective feelings, and thus they are unable to monitor and observe changes in the patient's condition in a timely manner, and then adjust the corresponding treatment strategy in a timely manner. Summary of the invention

[0003] The purpose of the present invention is to provide a stomach tube tail end fixing device to achieve relatively stable clamping and fixing of the stomach tube tail end.

[0004] The purpose of the present invention can be achieved by the following technical solutions:

[0005] A stomach tube tail end fixing device, comprising:

[0006] The first clamp body and the second clamp body each have a first end and a second end, and the middle parts of the first clamp body and the second clamp body are rotatably connected;

[0007] An elastic member, used for applying elastic force to the first clamp body and the second clamp body, so that the first ends of the first clamp body and the second clamp body are relatively close to each other;

[0008] The first and second gelatin sponge layers are respectively arranged on the inner sides of the first ends of the first and second clamps. When the first and second clamps are relatively close to each other to the maximum, a clamping cavity is formed between the first and second gelatin sponge layers for the tail end of the gastric tube to extend into.

[0009] Furthermore, the middle parts of the first clamping body and the second clamping body are rotatably connected via a pin shaft.

[0010] Furthermore, the elastic member is a compression spring whose two ends are respectively connected to the first clamping body and the second end of the second clamping body, or a torsion spring arranged on the pin shaft.

[0011] Furthermore, the relative surfaces of the first gelatin sponge layer and the second gelatin sponge layer are respectively provided with a groove with a semicircular cross-section, and along the direction of the rotation center axis of the first clamp and the second clamp, the groove extends from the bottom end to the upper and middle parts of the first gelatin sponge layer and the second clamp, and when the first ends of the first clamp and the second clamp are close together, the two grooves cooperate to form the clamping cavity.

[0012] Furthermore, the first clamping body and the second clamping body are respectively processed with a concave receiving groove, and the first gelatin sponge layer and the second gelatin sponge layer are placed in the receiving groove.

[0013] Furthermore, the size of the receiving groove is no larger than the first gelatin sponge layer and the second gelatin sponge layer.

[0014] Furthermore, a gap extending from the top to the middle and lower part is reserved between the first clamp and the first gelatin sponge layer, and a pH test strip for monitoring gastric reflux can be inserted into the gap.

[0015] Furthermore, the length of the slit satisfies that when the pH test strip is inserted to the bottom, the top of the pH test strip is still partially exposed.

[0016] Furthermore, the area on the first clamping body corresponding to the gap is transparent or hollow.

[0017] Furthermore, the second clamping body is provided with a fixing protrusion, and a hole is processed on the fixing protrusion, and a rope belt for clamping the patient's clothes is arranged in the hole.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] (1) The "clip" structure is composed of a first clamp body and a second clamp body. At the same time, a gelatin sponge layer is provided, which can not only effectively prevent the tail end of the gastric tube from being damaged by excessive clamping force, but also play a buffering and protective role. At the same time, the gelatin sponge can also absorb a small amount of overflowed gastric juice to prevent further overflow to the bed or other places. In addition, it can also increase the friction force on the tail end of the gastric tube to prevent it from falling off, so that the tail end of the gastric tube can be well fixed and wrapped.

[0020] (2) A gap is reserved between the first clamp and the first gelatin sponge layer, where a pH test strip is placed. When a patient has a small amount of gastric juice reflux that is not easily noticed, although it is affected by the intermediate reflux process, the gastric juice absorbed by the gelatin sponge layer is generally still acidic. In this way, this information can be effectively detected by the pH test strip and can be more easily observed by the monitoring personnel through color changes, thereby facilitating the adjustment of subsequent treatment strategies.

[0029] In the following implementation manners or examples, unless otherwise specified, functional components or structures are conventional components or conventional structures used in the art to achieve corresponding functions.

[0030] In order to achieve relatively stable clamping and fixing of the tail end of the gastric tube, the present invention provides a gastric tube tail end fixing device, see Figures 1 to 3 As shown, including:

[0031] The first clamping body 1 and the second clamping body 2 each have a first end and a second end, and the middle parts of the first clamping body 1 and the second clamping body 2 are rotatably connected;

[0032] An elastic member 3, which is used to apply elastic force to the first clamp body 1 and the second clamp body 2, so that the first ends of the first clamp body 1 and the second clamp body 2 are relatively close to each other;

[0033] The first gelatin sponge layer 4 and the second gelatin sponge layer 5 are respectively arranged on the inner sides of the first ends of the first clamp 1 and the second clamp 2. When the first clamp 1 and the second clamp 2 are relatively close to each other to the maximum, a clamping cavity 6 is formed between the first gelatin sponge layer 4 and the second gelatin sponge layer 5 for the tail end of the gastric tube to extend into.

[0034] In some specific embodiments, the middle parts of the first clamp body 1 and the second clamp body 2 are rotatably connected via a pin shaft. At this time, during operation, the first ends of the first clamp body 1 and the second clamp body 2, namely, the clamping ends, cooperate with the elastic member 3 to clamp the tail end of the gastric tube, and the second ends, namely, the pressing ends, are pressed to loosen or clamp the clamping ends.

[0035] In a more specific embodiment, the elastic member 3 is a compression spring whose two ends are respectively connected to the first clamp body 1 and the second end of the second clamp body 2, or a torsion spring arranged on the pin. Preferably, the elastic member 3 can be a torsion spring. This is a conventional technical means in the art and does not belong to the innovative protection point of the present invention, and will not be repeated here.

[0036] In some specific embodiments, the relative surfaces of the first gelatin sponge layer 4 and the second gelatin sponge layer 5 are respectively provided with a groove with a semicircular cross-section, and along the direction of the rotation center axis of the first clamp 1 and the second clamp 2, the groove extends from the bottom end to the middle and upper parts of the first gelatin sponge layer 4 and the second gelatin sponge layer 5, and when the first ends of the first clamp 1 and the second clamp 2 are close together, the two grooves cooperate to form the clamping cavity 6.

[0037] In some specific embodiments, the first clamping body 1 and the second clamping body 2 are respectively processed with a concave receiving groove 7, and the first gelatin sponge layer 4 and the second gelatin sponge layer 5 are placed in the receiving groove 7. In a more specific embodiment, the size of the receiving groove 7 is not larger than the first gelatin sponge layer 4 and the second gelatin sponge layer 5. The first gelatin sponge layer 4 and the second gelatin sponge layer 5 are installed in the receiving groove 7 by pressing in. When replacement is needed, it is only necessary to pull out the corresponding gelatin sponge layer and replace it with a new gelatin sponge layer.

[0038] In some specific embodiments, a gap 8 extending from the top to the middle and lower part is reserved between the first clamp 1 and the first gelatin sponge layer 4, and a pH test strip 9 for monitoring gastric reflux can be inserted into the gap 8.

[0039] In a more specific embodiment, the length of the slit 8 satisfies that when the pH test strip 9 is inserted to the bottom, the top of the pH test strip 9 is still partially exposed.

[0040] Furthermore, the area on the first clamp 1 corresponding to the gap 8 is transparent or hollowed out to facilitate observation of the information on the pH test strip 9 .

[0041] In some specific embodiments, the second clamp body 2 is further provided with a fixing protrusion 10, and a hole 11 is processed on the fixing protrusion 10. The hole 11 is used to set a rope for clamping the patient's clothes. Through this fixing protrusion 10, the device can be conveniently fixed on the patient's clothes.

[0042] The above embodiments may be implemented individually or in any combination of two or more.

[0043] The above implementation is described in more detail below in conjunction with specific examples.

[0044] Embodiment 1:

[0045] In order to achieve relatively stable clamping and fixing of the tail end of the gastric tube 12, this embodiment provides a gastric tube tail end fixing device, see Figures 1 to 3 As shown, including:

[0046] The first clamping body 1 and the second clamping body 2 each have a first end and a second end, and the middle parts of the first clamping body 1 and the second clamping body 2 are rotatably connected;

[0047] An elastic member 3, which is used to apply elastic force to the first clamp body 1 and the second clamp body 2, so that the first ends of the first clamp body 1 and the second clamp body 2 are relatively close to each other;

[0048] The first gelatin sponge layer 4 and the second gelatin sponge layer 5 are respectively arranged on the inner sides of the first ends of the first clamp 1 and the second clamp 2. When the first clamp 1 and the second clamp 2 are relatively close to each other to the maximum, a clamping cavity 6 is formed between the first gelatin sponge layer 4 and the second gelatin sponge layer 5 for the tail end of the gastric tube to extend into.

[0049] In this embodiment, the middle part of the first clamp body 1 and the second clamp body 2 are rotatably connected by a pin. At this time, during operation, the first end of the first clamp body 1 and the second clamp body 2, that is, the clamping end, cooperates with the elastic member 3 to achieve the clamping effect on the tail end of the gastric tube, and the second end, as the pressing end, realizes the loosening or clamping action of the clamping end by pressing. The elastic member 3 is a compression spring whose two ends are respectively connected to the second ends of the first clamp body 1 and the second clamp body 2.

[0050] In this embodiment, the relative surfaces of the first gelatin sponge layer 4 and the second gelatin sponge layer 5 are respectively provided with a groove with a semicircular cross-section, and along the direction of the rotation center axis of the first clamp body 1 and the second clamp body 2, the groove extends from the bottom end to the upper and middle parts of the first gelatin sponge layer 4 and the second gelatin sponge layer 5, and when the first ends of the first clamp body 1 and the second clamp body 2 are close together, the two grooves cooperate to form the clamping cavity 6.

[0051] In this embodiment, the first clamping body 1 and the second clamping body 2 are respectively processed with a concave receiving groove 7, and the first gelatin sponge layer 4 and the second gelatin sponge layer 5 are placed in the receiving groove 7. The size of the receiving groove 7 is not larger than the first gelatin sponge layer 4 and the second gelatin sponge layer 5. The first gelatin sponge layer 4 and the second gelatin sponge layer 5 are installed in the receiving groove 7 by pressing in. When replacement is needed, it is only necessary to pull out the corresponding gelatin sponge layer and replace it with a new gelatin sponge layer.

[0052] The second clamp body 2 is also provided with a fixing protrusion 10, and a hole 11 is processed on the fixing protrusion 10. The hole 11 is used to set a rope for clamping the patient's clothes. Through this fixing protrusion 10, the device can be conveniently fixed on the patient's clothes.

[0053] The stomach tube tail end fixing device of the present embodiment adopts a "clip" structure composed of a first clamp body 1 and a second clamp body 2. At the same time, a gelatin sponge layer is provided, which can not only effectively prevent the tail end of the stomach tube from being damaged due to excessive clamping force, but also play a buffering and protective role. At the same time, the gelatin sponge can also absorb a small amount of overflowed gastric juice to prevent further overflow to the bed or other places. In addition, it can also increase the friction force on the tail end of the stomach tube to prevent it from falling off, so that the tail end of the stomach tube can be well fixed and wrapped to prevent external impurities from entering the stomach tube and other displacement problems.

[0054] Embodiment 2:

[0055] Based on Example 1, please refer to Figures 1 to 3 As shown, in this embodiment, a gap 8 extending from the top to the middle and lower part is reserved between the first clamp 1 and the first gelatin sponge layer 4, and a pH test strip 9 for monitoring gastric reflux can be inserted into the gap 8. The length of the gap 8 satisfies that when the pH test strip 9 is inserted to the bottom, the top of the pH test strip 9 is still partially exposed. The area on the first clamp 1 corresponding to the gap 8 is transparent or hollowed out to facilitate observation of the information of the pH test strip 9.

[0056] In this embodiment, a gap 8 is reserved between the first clamp 1 and the first gelatin sponge layer 4, and a pH test strip 9 is placed therein. When a patient has a small amount of gastric juice reflux that is not easily noticed, although it is affected by the intermediate reflux process, the gastric juice absorbed by the gelatin sponge layer is generally still acidic. In this way, this information can be effectively detected by the pH test strip 9 and can be more easily observed by the monitoring personnel through color changes, thereby facilitating the adjustment of subsequent treatment strategies.

[0057] The above description of the embodiments is to facilitate the understanding and use of the invention by those skilled in the art. It is obvious that those skilled in the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative work. Therefore, the present invention is not limited to the above embodiments, and improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the present invention should be within the scope of protection of the present invention.
