Description

Technical Field

[0001] The utility model belongs to the technical field of gastric tube positioning mechanisms, and particularly relates to a soothing neonatal gastric tube positioning mechanism. Background Technique

[0002] A gastric tube is a flexible tube used in medicine, usually made of materials such as silicone or polyurethane, and its purpose is to directly deliver liquid food, moisture, drugs, etc. into the stomach of a patient. The gastric tube can be inserted through different routes, but the most common is through the nasal cavity (nasogastric tube) or directly through percutaneous puncture into the stomach (such as percutaneous gastrostomy). Gastric tube insertion is a commonly used technical operation for critically ill neonates, mainly for neonates with low sucking and swallowing abilities and neonates who cannot eat orally due to various diseases. To ensure sufficient energy supply, a gastric tube is often indwelled, and then nasogastric feeding is adopted.

A connecting frame is rotatably connected to the side wall of the barrel sleeve. A suction cup is fixed on the connecting frame, and the suction cup can rotate around the syringe, and the adsorption surface of the suction cup is converted in different orientations.

[0004] In the above patent, when the gastric tube is in use, it is connected to the syringe, and then adsorbed and positioned through the suction cup. The suction cup can be adsorbed by squeezing the air pressure in the suction cup inward. However, when the suction cup needs to be removed, due to the reason of atmospheric pressure, the suction cup will tightly adhere to the surface, which will cause inconvenience during removal. Content of the Utility Model

[0009] Preferably, a conduit is connected to the opening of one end of the communication hole I extending to the opening of the air extraction port. An air extraction pipe extends along the communication hole II to the outer peripheral surface of the conduit. Inside the air extraction hole, the gas inside the suction cup head can be discharged through a one-way valve to form one-way exhaust.

[0010] Preferably, push rods are respectively provided on both sides of the surface of the baffle. One end of the push rod is located inside the telescopic groove provided on the surface of the electric suction cup. At the same time, a limiting baffle is provided on one side of the inner wall of the air extraction chamber. The displacement of the baffle can be limited and blocked by two opposite limiting baffles.

[0011] Preferably, the inner ring of the clamp also tightens the syringe through a contraction member.

[0016] The soothing type neonatal gastric tube positioning mechanism of the present utility model has the following advantages:

[0017] 1. This soothing neonatal gastric tube positioning mechanism uses a motor to drive the impeller. The negative pressure generated by the rotation of the impeller acts through the second connecting hole and the exhaust hole, causing the suction cup head to be adsorbed on the surface of the incubator.

For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.

[0040] The disclosure below provides many different embodiments or examples for realizing different structures of the embodiments of the present utility model. In order to simplify the disclosure of the embodiments of the present utility model, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the embodiments of the present utility model. In addition, the embodiments of the present utility model can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0041] In order to better understand the purpose, structure and function of the utility model, the utility model is further described in detail below with reference to the accompanying drawings.

[0042] like Figures 1 - 6 The main technical contents of the first specific embodiment are shown. In the first embodiment, the core of the technical solution includes a gastric tube 2 with one end inserted from the nostril, and a discharge hole 21 is opened on the outer peripheral surface of the insertion end of the gastric tube 2, through which the corresponding nutrient solution can be delivered to the stomach through the gastric tube 2. The other terminal of the gastric tube 2 is connected to a syringe 1, which has an open end and a hollow structure, and is intended to accommodate a piston 11. A needle 12 is arranged on the upper part of the piston 11, so that when one end of the gastric tube 2 is inserted into the stomach, the gas accumulated in the stomach can be smoothly transferred to the inside of the syringe 1 through the gastric tube 2, and finally released through the needle 12, so as to achieve the purpose of effectively reducing the pressure in the stomach. In addition, the gastric tube 2 is designed in a three-way shape, which is convenient for additionally connecting a device for delivering nutrient solution on the other side, thereby enhancing the flexibility and convenience of use.

[0043] The outside of the syringe barrel 1 is equipped with a clamp 3 which is designed with a bayonet 37 to easily fix and lock the syringe barrel 1 in place. The inner edge of the clamp 3 also uses a shrinkage member to further secure the syringe barrel 1 and improve its adaptability. In addition, an electric suction cup 4 is assembled on one side of the syringe barrel 1, and its function is to adsorb on the outer shell of the incubator. Through the flexible connection of the connecting rod 31, one end of it is hinged to the electric suction cup 4 and the other end is connected to the clamp 3. Such a mechanical structure arrangement enables the electric suction cup 4 to flexibly fit on the top or side of the incubator, thus ensuring that the gastric tube 2 maintains an appropriate and stable position during use, improving the overall safety and user experience.

[0044] The electric suction cup 4 performs surface adsorption operations through its suction cup head 41, enhancing the fixing ability of the device on the incubator. The suction cup head 41 not only realizes physical adsorption, but also integrates an air extraction hole 42 and an exhaust hole 43 on its adsorption surface. The functions of these two holes are as follows: the air extraction hole 42 is used to extract air to generate negative pressure, so that the suction cup head 41 can firmly adsorb on the surface of the object; when it is necessary to remove the suction cup, air is inflated through the exhaust hole 43, and under the action of positive pressure, the suction cup head 41 can be easily detached. In addition, the electric suction cup 4 also integrates a white noise generator 5, which can play specific white noise according to medical instructions, which has a positive effect on calming the emotions of newborns and promoting their peaceful sleep. In addition, an exhaust hole 46 is designed on the outer surface of the electric suction cup 4.

[0045] As Figures 6 - 12 shown, an air extraction chamber 48 is opened inside the electric suction cup 4, and a motor 7 is installed on the wall of the chamber. The motor 7 drives the impeller 74 to rotate rapidly through its rotating shaft. The impeller 74 is covered with a volute 71 to optimize the air flow direction. At the same time, an air extraction port 73 is opened on the front of the volute 71, and an exhaust hole 72 is provided at the top, forming a gas flow path. The air extraction port 73 is communicated with the air extraction hole 42 on the suction cup head 41. When the motor 7 drives the impeller 74 to rotate at a high speed, air is quickly extracted through the air extraction port 73 and the air extraction hole 42, thereby generating sufficient negative pressure between the suction cup head 41 and the contact surface, ensuring that the suction cup head 41 can firmly adsorb on the surface of the incubator.

[0046] Inside the electric suction cup 4, a movable baffle 6 is also provided. The baffle 6 closely adheres to the inner wall of the air extraction chamber 48 and covers the through-opening surfaces of the air extraction hole 42 and the first exhaust hole 43. The baffle 6 itself has two channels: the first communication hole 65 and the second communication hole 62, which are respectively connected in an alternating manner with the first exhaust hole 43 and the air extraction hole 42, and this design promotes the directional control of the air flow. Further, one end of the first communication hole 65 is directly connected to the air extraction port 73 through a conduit 64, realizing a smooth transition of the air flow from the suction cup head 41 to the air extraction system, while the second communication hole 62 guides the air flow towards the air extraction pipe 63. And a check valve 47 is installed inside the air extraction hole 42, and its function is to only allow the gas to be discharged from the inside of the suction cup head 41 and not to flow back, ensuring the high efficiency and stability of the suction cup operation, that is, realizing the function of one-way exhaust.

[0047] In this embodiment, push rods 61 are arranged on both sides of the baffle 6, and one ends of these push rods 61 are embedded in the telescopic grooves 44 on the outer surface of the electric suction cup 4. By pressing the push rod 61 on either side, the user can cause the baffle 6 to slide horizontally. To ensure that the sliding range of the baffle 6 is controlled, two oppositely arranged limit baffles 45 are installed on the inner wall of the air extraction chamber 48, and they jointly limit the moving range of the baffle 6 to prevent excessive sliding. In practical applications, when it is necessary to fix the gastric tube 2, first attach the suction cup head 41 to the surface of the incubator, then start the motor 7 to drive the impeller 74 to rotate at a high speed. Through the communication path between the second communication hole 62 and the air extraction hole 42, the suction force generated by the impeller 74 will continuously extract the air inside the suction cup head 41, forming a strong adsorption force to ensure that the suction cup head 41 is firmly adhered to the surface of the incubator. When it is necessary to remove the suction cup head 41, the operator only needs to press the push rod 61 on the appropriate side, which will cause the baffle 6 to displace, resulting in the second communication hole 62 no longer communicating with the air extraction hole 42, and at the same time, the first communication hole 65 is connected to the first exhaust hole 43, allowing the outside gas to flow into the inside of the suction cup head 41, destroying the original vacuum state, so that the suction cup head 41 can be easily separated from the surface of the incubator.

[0048] As Figures 11 - 12As shown, the contraction member is composed of an inflatable expansion film 33, and the expansion film 33 is integrated into the cavity 32 opened in the inner ring of the clamp 3. The inner wall of the clamp 3 is designed to be hollow, providing a space for accommodating the expansion film 33. To achieve the functions of inflation and exhaust, an inflation hole 34 is opened on the outer surface of the clamp 3, and is connected to the exhaust hole 72 of the electric suction cup 4 through a connecting pipe 8. One end of this connecting pipe 8 passes through the second exhaust hole 46 and is connected to the third exhaust hole 72, forming a closed gas path system. The working principle is as follows: When the motor 7 drives the impeller 74 to rotate for air extraction, the generated airflow will be discharged through the third exhaust hole 72, and then introduced into the interior of the clamp 3 through the connecting pipe 8 and the inflation hole 34. With the injection of gas, the expansion film 33 begins to expand, enabling the clamp 3 to flexibly adjust its diameter to adapt to syringes 1 of different specifications, achieving adaptive contraction and fastening of the syringe 1 and enhancing the flexibility of use.

[0049] As Figures 13 - 14 shown in the main technical content of the second specific embodiment, although maintaining the same core design concept as the first embodiment, the contraction member is improved. The contraction member is composed of a magic tape 9. One end of the magic tape 9 starts from the cavity 32 opened in the inner ring of the clamp 3, passes through a preset notch 36, and then bypasses the retaining ring 35 configured at the distal end of the clamp 3. The magic tape 9 has two sides: a fuzzy side 91 and a corresponding prickly side, which can firmly adhere when in contact. When it is necessary to fix the syringe 1, the user only needs to pull out one end of the magic tape 9 through the notch 36, bypass the retaining ring 35 and pull it back tightly. Through the close combination of the fuzzy side 91 and the prickly side, stable and adjustable fixation of the syringe 1 is achieved.

[0050] The working principle of a soothing neonatal gastric tube positioning mechanism: When it is necessary to fix the gastric tube 2, first attach the suction cup head 41 to the surface of the incubator, and then start the motor 7 to drive the impeller 74 to rotate at high speed. Through the communication path between the second communication hole 62 and the air extraction hole 42, the suction force generated by the impeller 74 will continuously extract the air inside the suction cup head 41, forming a strong adsorption force to ensure that the suction cup head 41 is firmly adhered to the surface of the incubator. When it is necessary to remove the suction cup head 41, the operator only needs to press the push rod 61 on the appropriate side, which will displace the baffle 6, causing the second communication hole 62 and the air extraction hole 42 to no longer communicate, and at the same time the first communication hole 65 is connected to the first exhaust hole 43, allowing external gas to flow into the interior of the suction cup head 41, destroying the original vacuum state. Thus, the suction cup head 41 can be easily separated from the surface of the incubator. At the same time, when the contraction member needs to further contract and fasten the syringe 1, it can be achieved through the expansion film 33 and the magic tape 9 respectively.

[0051] It can be understood that the present utility model is described by means of some embodiments. Those skilled in the art will know that, without departing from the spirit and scope of the present utility model, various changes or equivalent substitutions can be made to these features and embodiments. Additionally, under the teaching of the present utility model, these features and embodiments can be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application belong to the scope protected by the present utility model.
