Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary devices, and particularly relates to a gravity feeding device. Background Art

[0002] Premature infants refer to live-born infants born before 37 full weeks of gestation. Due to the underdevelopment of the organ functions of premature infants and the incoordination of sucking and swallowing functions, problems such as low feeding efficiency and slow weight gain are likely to occur during feeding. In order to improve the feeding efficiency of premature infants and establish normal gastrointestinal functions, gravity feeding is generally used for premature infants in clinical practice. Gravity feeding is a method that uses gravity to make the milk flow naturally into the stomach through a gastric tube. Gravity feeding can make the milk flow slowly and evenly into the stomach of premature infants, have less impact on the stomach, and can significantly reduce the incidence of feeding intolerance. Clinically, the prepared milk is generally poured into an empty syringe connected to the gastric tube, and then the syringe is placed at a high position so that the milk flows naturally into the stomach of the newborn through the action of gravity. Since premature infants are difficult to adapt to the external environment, premature infants are generally placed in an incubator. At present, there is no device in the incubator that can fix the syringe. Some incubators are provided with round holes above. Usually, medical staff will vertically insert the lower half of the syringe into the round hole and fix it, and then connect the syringe to the gastric tube. However, there are also some incubators without round holes above. In this case, medical staff generally hold the syringe to perform gravity feeding on premature infants. Since the feeding process is relatively long, it is quite laborious for the medical staff holding the syringe.

[0003] Chinese patent document CN216536161U discloses a neonatal gravity feeder, including a syringe and a gastric tube. The syringe includes a syringe barrel and a handle. One end of the syringe barrel is provided with an opening, and the other end is provided with a needle tip. The end of the needle tip far from the syringe barrel is detachably connected to the gastric tube. A piston is installed at one end of the handle, and a hanging ring is installed at the other end. The end of the handle where the piston is installed is slidably installed in the syringe barrel through the piston; a vent hole is provided on the syringe barrel, and a liquid valve is installed on the needle tip. The above technical solution can be hung on an external hook through the hanging ring, thus solving the problem that medical staff need to hold the syringe barrel all the time during gravity feeding and reducing the work burden of medical staff. However, the above technical solution still has at least the following disadvantages: 1) In the above solution, an additional hook for hanging the hanging ring needs to be configured, and there is generally no suitable position around the incubator for setting the hook, which easily leads to limited use scenarios; 2) The stability of the hanging ring hanging method is poor, which easily causes the entire device to shake and easily pulls the gastric tube, thereby causing injury to the baby.

[0004] Therefore, there is a need to provide a gravity feeding device that is convenient to fix and firmly fixed. Summary of the Utility Model

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the technical defects in the prior art that the gravity feeding device needs to be additionally configured with a hook to be fixed, resulting in limited usage scenarios; at the same time, the hanging method using a hanging ring has poor stability and is easy to cause traction on the gastric tube, thereby causing damage to the baby, thereby providing a gravity feeding device that is easy to fix and firmly fixed.

[0006] To this end, the utility model provides a gravity feeding device, comprising:

[0014] Furthermore, the locking structure comprises:

[0015] An adjustment opening is provided on the second magnetic attraction member along a direction parallel to the central axis of the mounting hole and is communicated with the mounting hole;

[0016] an adjusting through hole, which penetrates through the inside of the second magnetic attraction member arranged on both sides of the adjusting opening and intersects the adjusting opening vertically, wherein the adjusting through hole comprises a light hole section and a thread section; the thread section is arranged on the second magnetic attraction member on one side of the adjusting opening;

[0017] A locking bolt that can be inserted through the light hole section and threadedly connected to the threaded section; the outer diameter of the bolt head of the locking bolt is greater than the inner diameter of the light hole section. When the locking bolt is screwed, the second magnetic attracting members on both sides of the adjusting opening can be made to approach each other, reducing the inner diameter of the mounting hole and thus tightly clamping and fixing the mounting shaft.

[0018] Further, at least a part of the adjusting through hole intersects with the mounting hole;

[0030] The present utility model is fixed by using a first magnetic attraction member and a second magnetic attraction member to attract and press tightly on the box body. It is not necessary to additionally provide a fixing device outside the box body, nor to change the existing structure of the incubator, thus facilitating use. When it is necessary to adjust the position of the liquid storage tube, only the first magnetic attraction member and the second magnetic attraction member need to be moved correspondingly, so that the device can be conveniently fixed at different positions on the box body, thereby improving the applicable range of the device. At the same time, the first magnetic attraction member and the second magnetic attraction member attract and press tightly on the box body, which can improve the stability of the liquid storage tube, prevent the gastric tube from being pulled due to the shaking of the liquid storage tube, and thus avoid causing damage to the baby.

[0041] The following will detail this application with reference to the drawings and in combination with embodiments.

[0042] This embodiment provides a gravity feeding device, as Figures 1-5 shown, comprising a storage esophagus 1, a fixing base 2 and a clamping member 3; the storage esophagus 1 is used for containing the feeding liquid, a liquid adding port 11 is arranged at the upper end of the storage esophagus 1, and a liquid outlet 12 adapted to be connected to a gastric tube is arranged at the lower end; the fixing base 2 comprises a first magnetic member 21 and a second magnetic member 22 that can magnetically attract each other; the clamping member 3 is rotatably installed on the second magnetic member 22 and is used for clamping and fixing the storage esophagus 1.

[0043] For the gravity feeding device of this embodiment, during use, the storage esophagus 1 is clamped and fixed on the clamping member 3; the first magnetic member 21 and the second magnetic member 22 are correspondingly placed on the inner and outer sides of the designated position of the incubator box body, so that the first magnetic member 21 and the second magnetic member 22 attract each other and are tightly pressed and fixed on the box body; the angle of the storage esophagus 1 is adjusted by rotating the clamping member 3, thereby completing the installation of the gravity feeding device.

[0044] In this embodiment, magnets can be provided in the first magnetic component 21 and the second magnetic component 22. By using the first magnetic component 21 and the second magnetic component 22 to attract and press them against the box body for fixing, there is no need to provide an additional fixing device outside the box body, and there is no need to change the existing structure of the incubator, so that it is convenient to use; when the position (for example, the height) of the food storage tube 1 needs to be adjusted, it is only necessary to move the first magnetic component 21 and the second magnetic component 22 to the corresponding positions, so that the device can be conveniently fixed at different positions of the box body, thereby improving the scope of application of the device; at the same time, the first magnetic component 21 and the second magnetic component 22 are attracted and pressed against the box body, which can improve the stability of the food storage tube 1 and prevent the food storage tube 1 from being pulled on the gastric tube due to shaking, thereby avoiding damage to the baby.

[0045] The gravity feeding device of this embodiment further comprises: the first magnetic member 21 has a first magnetic plane 211; the second magnetic member 22 has a second magnetic plane 221 formed on one side thereof which can be attracted to the first magnetic plane 211, and the clamping member 3 is installed on the other side thereof.

[0046] In the gravity feeding device of this embodiment, the second magnetic member 22 is provided with a mounting hole 222, and the central axis of the mounting hole 222 is perpendicular to the second magnetic plane 221; the clamping member 3 is provided with a mounting shaft 31, and the mounting shaft 31 is suitable for being rotatably inserted into the mounting hole 222 from the side away from the second magnetic plane 221; a locking structure is provided between the second magnetic member 22 and the mounting shaft 31, and the locking structure is used to lock and fix the mounting shaft 31 to the second magnetic member 22.

[0047] In this embodiment, the vertical angle of the food storage tube 1 can be adjusted by rotating the installation shaft 31, and after the adjustment, the installation shaft 31 can be locked and fixed by the locking structure.

[0048] For the gravity feeding device of this embodiment, further, the locking structure includes an adjustment opening 223, an adjustment through hole, and a locking bolt 226; the adjustment opening 223 is disposed through the second magnetic attracting member 22 along a direction parallel to the central axis of the mounting hole 222 and communicates with the mounting hole 222; the adjustment through hole is disposed through the inside of the second magnetic attracting member 22 on both sides of the adjustment opening 223 and perpendicularly intersects with the adjustment opening 223, and the adjustment through hole includes a light hole section 224 and a threaded section 225; the threaded section 225 is disposed on the second magnetic attracting member 22 on one side of the adjustment opening 223; the locking bolt 226 can be inserted from the light hole section 224 and is screwed to the threaded section 225; the outer diameter of the bolt head of the locking bolt 226 is greater than the inner diameter of the light hole section 224, and when the locking bolt 226 is screwed, the second magnetic attracting members 22 on both sides of the adjustment opening 223 can be made to approach each other so that the inner diameter of the mounting hole 222 becomes smaller, and further the mounting shaft 31 is tightly held and fixed.

[0049] In this embodiment, the inner diameter of the mounting hole 222 can be changed as the size of the adjustment opening 223 changes. When the inner diameter of the mounting hole 222 becomes larger, the mounting shaft 31 can freely rotate in the mounting hole 222. When the mounting hole 222 becomes smaller, the inner wall of the mounting hole 222 can tightly hold and fix the mounting shaft 31. The locking bolt 226 can be inserted from the light hole section 224 and is screwed to the threaded section 225. The outer diameter of the bolt head of the locking bolt 226 is greater than the inner diameter of the light hole section 224. Thus, after the bolt head of the locking bolt 226 is in close contact with the end face of the second magnetic attracting member 22 at one end of the light hole section 224, the locking bolt 226 can rotate in the adjustment through hole without axial movement. At this time, when the locking bolt 226 is screwed and rotated in the direction of screwing into the threaded section 225, the second magnetic attracting members 22 on both sides of the adjustment opening 223 can approach each other under the action of the locking bolt 226 so that the inner diameter of the mounting hole 222 becomes smaller, thereby tightly holding the mounting shaft 31; when the locking bolt 226 is screwed and rotated in the direction of screwing out of the threaded section 225, the second magnetic attracting members 22 on both sides of the adjustment opening 223 can recover deformation and move away from each other so that the inner diameter of the mounting hole 222 becomes larger, thereby loosening the mounting shaft 31.

[0050] For the gravity feeding device of this embodiment, further, at least part of the adjustment through hole intersects with the mounting hole 222; an arc-shaped recess 311 is formed on the part of the mounting shaft 31 inserted into the mounting hole 222; after the locking bolt 226 is inserted into the adjustment through hole, the locking bolt 226 can partially enter the arc-shaped recess 311.

[0051] In this embodiment, at least a part of the adjusting through-hole intersects with the mounting hole 222. After the locking bolt 226 is inserted into the adjusting through-hole, at least a part of the locking bolt 226 is located inside the mounting hole 222. After the mounting shaft 31 is inserted into the mounting hole 222, the part of the locking bolt 226 located in the mounting hole 222 can enter the inside of the arc-shaped recess 311, so as to form a limit in the axial direction on the mounting shaft 31 and prevent the mounting shaft 31 from disengaging from the mounting hole 222.

[0052] In the gravity feeding device of this embodiment, further, it further includes a tube clamp 227. The tube clamp 227 is arranged on the second magnetic member 22 and is used for fixing the gastric tube.

[0053] In this embodiment, by arranging the tube clamp 227, the gastric tube can be fixed, thereby preventing the gastric tube from shaking.

[0054] In the gravity feeding device of this embodiment, further, it further includes a ventilation plug 4. The ventilation plug 4 is openably and closably covered on the liquid adding port 11 of the storage esophageal tube 1.

[0055] In this embodiment, the ventilation plug 4 can prevent foreign objects from falling into the storage esophageal tube 1 and contaminating the feeding liquid.

[0056] In the gravity feeding device of this embodiment, further, a filling port 41 is arranged at the top end of the ventilation plug 4, and the filling port 41 is communicated with the inside of the storage esophageal tube 1.

[0057] In this embodiment, the filling port 41 can be communicated with an external pipeline, so as to facilitate the replenishment of the feeding liquid in the storage esophageal tube 1.

[0058] In the gravity feeding device of this embodiment, further, a scale 13 is arranged on the storage esophageal tube 1.

[0059] In this embodiment, the scale 13 can ensure more accuracy when adding the feeding liquid, and at the same time facilitate the observation and recording of the amount of the feeding liquid in the storage esophageal tube 1.

[0060] The using process of the gravity feeding device of this embodiment is as follows:

[0061] Insert the installation shaft 31 into the installation hole 222, insert the locking bolt 226 into the adjustment through-hole and partially enter the inside of the arc-shaped recess 311 of the installation shaft 31; use the first magnetic part 21 and the second magnetic part 22 to fix the clamping part 3 at the designated position on the inner wall of the incubator, clamp and fix the feeding tube 1 on the clamping part 3, and adjust the angle of the feeding tube 1. After the adjustment is completed, tighten the locking bolt 226 to fix the installation shaft 31; fix the gastric tube on the tube clamp 227 to prevent the gastric tube from shaking; monitor the feeding liquid in the feeding tube 1 according to the scale 13. When it is necessary to supplement the feeding liquid, add the feeding liquid to the feeding tube 1 through the external pipeline connected to the filling port 41; when it is necessary to adjust the position of the feeding tube 1, just move the first magnetic part 21 and the second magnetic part 22 to the corresponding positions.

[0062] Obviously, the above embodiments are merely examples given for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of this innovative technical solution.
