[0024] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0027] Example 1

[0028] Reference Figure 1-2 , which is the first embodiment of the utility model, provides a gravity tube feeder. By setting a breathable member 105, it is avoided that medical staff have to use tools to clear the vent hole in order to make the vent hole pass through, which not only reduces the labor intensity of medical staff, but also prevents dust from falling into the container and contaminating the clean liquid food.

[0029] Specifically, the ventilation assembly 100 includes a cover 101, a breathable member 105 arranged on the top of the cover 101, and a placement shell 106 arranged at the bottom of the breathable member 105; an anti-blocking cavity 101a is opened at the bottom of the cover 101, the breathable member 105 includes a pressing member 105a and a reset member 105b arranged at the bottom of the pressing member 105a, a handle 102 is arranged on the top of the cover 101, a connecting block 103 is arranged on one side of the cover 101, and a positioning rod 104 is arranged on the connecting block 103.

[0030] Among them, the placement shell 106 is fixedly connected to the top inner wall of the cover 101, and the air permeable member 105 passes through the hole of the cover 101 to perform piston movement. When the air permeable member 105 descends, the gap between the placement shell 106 and the cover 101 is exposed. When the air permeable member 105 rises, the gap between the placement shell 106 and the cover 101 is blocked.

[0031] In summary, by providing the breathable member 105, the breathable member 105 is pressed to make it go down, exposing the gap between the housing shell 106 and the cover 101; when the breathable member 105 rises, the gap between the housing shell 106 and the cover 101 is blocked, thereby preventing medical staff from having to use tools to clear the vent holes in order to make the vent holes pass through. This not only reduces the labor intensity of medical staff, but also prevents dust from falling into the container and contaminating the clean liquid food.

[0032] Example 2

[0033] Reference Figure 1 to Figure 4 , which is the second embodiment of the utility model. Different from the previous embodiment, this embodiment is provided with an anti-blocking cavity 101a. The advantage of such a setting is to prevent the liquid food in the container 203 from shaking and blocking the ventilation interval.

[0034] Specifically, the pressing piece 105a can slide in the placement shell 106, the reset piece 105b is arranged on the bottom inner wall of the placement shell 106, and a conveying component 200 is arranged at one end of the positioning rod 104 away from the connecting block 103. The conveying component 200 includes a container 203, a flow rate control valve 202 arranged at the bottom of the container 203, and a gastric tube 201 arranged at the bottom of the flow rate control valve 202.

[0035] A scale 203a is provided on the container 203, and the pressing piece 105a includes an extrusion block 105a-1, a connecting rod 105a-8 arranged at the bottom center of the extrusion block 105a-1, a turntable 105a-6 arranged at the bottom of the connecting rod 105a-8 and a plurality of blocks 105a-7 arranged at the top of the turntable 105a-6, and a fixing ring 105a-4 is arranged on the inner wall of the housing 106.

[0036] Among them, the anti-blocking cavity 101a can provide a spacious space during the shaking of the liquid food, the connecting block 103 is rotatably connected to the positioning rod 104, the flow rate control valve 202 can adjust the flow rate of the liquid food, the scale 203a can observe the specific amount of the liquid food, and the connecting rod 105a-8 and the extrusion block 105a-1 are rotatably connected.

[0037] In summary, by setting the anti-blocking cavity 101a, the cover 101 is opened to pour the liquid food into the container 203, and then the pressing piece 105a is pressed to make the pressing piece 105a drop after the resetting piece 105b is reset, thereby exposing the gap between the placement shell 106 and the cover 101. Air can pass through the gap so that the liquid food in the container 203 flows into the gastric tube 201 at a certain speed under the action of gravity when passing through the flow rate control valve 202 under the regulation of the flow rate control valve 202, and finally flows into the patient's stomach through the gastric tube 201. The space of the anti-blocking cavity 101a is relatively large. The advantage of such a setting is to prevent the liquid food in the container 203 from shaking and blocking the ventilation gap.

[0038] Example 3

[0039] Reference Figure 1 to Figure 5 , which is the third embodiment of the utility model. Different from the previous embodiment, this embodiment is provided with a placement shell 106. The advantage of such a setting is to prevent dust from falling into the cover 101 from the gap when the cover 101 is left stationary for a long time.

[0040] Specifically, the blocking block 105a-7 is evenly arranged around the axis of the turntable 105a-6, and a plurality of first push rods 105a-2 and second push rods 105a-3 are provided at the bottom of the extrusion block 105a-1. The first push rods 105a-2 and the second push rods 105a-3 are evenly arranged around the axis of the extrusion block 105a-1, and the first push rods 105a-2 and the second push rods 105a-3 both pass through the fixing ring 105a-4.

[0041] A plurality of limit plates 105a-5 are provided at the bottom of the fixed ring 105a-4, and the reset member 105b includes a fixed tube 105b-1, a spring 105b-2 arranged in the fixed tube 105b-1, a sliding plate 105b-4 arranged on the top of the spring 105b-2 and a T-shaped limit rod 105b-3 arranged on one side of the sliding plate 105b-4, the sliding plate 105b-4 is rotatably connected to the rotating plate 105a-6, a sliding hole is opened on the fixed tube 105b-1, and a T-shaped limit rod 105b-3 is slidably connected in the sliding hole.

[0042] The limiting pieces 105a-5 are evenly arranged around the axis of the fixing ring 105a-4, the top of the clamping block 105a-7 is tilted downward, a sliding groove is provided at the bottom of the limiting piece 105a-5, and the bottom of the limiting piece 105a-5 and the bottom of the sliding groove are both in contact with the top of the clamping block 105a-7.

[0043] The distance from the top of the limiting piece 105 a - 5 to the top of the slide groove is greater than the distance from the top of the placement shell 106 to the top inner wall of the cover 101 .

[0044] A plurality of support rods 106 a are disposed on the housing 106 , and the support rods 106 a are evenly arranged around the axis of the housing 106 .

[0045] The support rod 106 a is fixedly connected to the bottom inner wall of the cover 101 , and the bottom area of ​​the cover 101 is larger than the top area of ​​the container 203 .

[0046] Among them, the uniform arrangement of the block 105a-7 around the axis of the turntable 105a-6 and the uniform arrangement of the limit plate 105a-5 around the axis of the fixed ring 105a-4 can improve the efficiency of the limit plate 105a-5 in limiting the block 105a-7. The top of the block 105a-7 is tilted downward to facilitate the spring 105b-2 to rotate and rise the block 105a-7 on the turntable 105a-6 along the bottom of the limit plate 105a-5 during the rising process when resetting.

[0047] The distance from the top of the limiting plate 105a-5 to the top of the slide groove is greater than the distance from the top of the placement shell 106 to the top inner wall of the cover 101, which is beneficial for the extrusion block 105a-1 to completely expose the gap between the placement shell 106 and the cover 101 after the lowering limit. The support rod 106a and the bottom inner wall of the cover 101 are fixedly connected. The bottom area of ​​the cover 101 is greater than the top area of ​​the container 203, which is beneficial for the cover 101 to prevent dust from falling into the container 203.

[0048] In summary, by setting the placement shell 106, the squeezing block 105a-1 is pressed to make the squeezing block 105a-1 descend and simultaneously push the connecting rod 105a-8, the first push rod 105a-2 and the second push rod 105a-3 to descend, the connecting rod 105a-8 pushes the rotating disk 105a-6 to descend, and the first push rod 105a-2 pushes the block 105a-7 on the rotating disk 105a-6 to descend. However, the force exerted by the first push rod 105a-2 on the block 105a-7 not only has a downward force, but also has a clockwise force on the block 105a-7 to the limiting plate 105a-5. Therefore, when the rotating disk 105a-6 pushes the sliding plate 105b-4 to descend, the sliding plate 105b-4 pushes the spring 105a-6 to push the sliding plate 105b-4 to push the spring 105a-6 to push the sliding plate 105b-4 to push the sliding plate 105b-4 to push the sliding plate 105b-4 to push the sliding plate 105a-6 to push the sliding plate 105a-6 to push the sliding plate 105a-4 ... When the top height of the card block 105a-7 is lower than the limiting piece 105a-5, the spring 105b-2 is reset to push the sliding plate 105b-4 to rise, and the rotating disk 105a-6 on the sliding plate 105b-4 pushes the connecting rod 105a-8, the first push rod 105a-2 and the second push rod 105a-3 to rise during the rising process, and the connecting rod 105a-8 drives the extrusion block 105a-1 to rise, and the card block 105a-7 rotates and rises along the bottom of the limiting piece 105a-5 to fit the slide groove on the limiting piece 105a-5 to limit the extrusion block 105a-1, exposing the gap between the placement shell 106 and the cover 101. When the extrusion block 105 is pressed again a-1, the extrusion block 105a-1 descends and simultaneously pushes the connecting rod 105a-8, the first push rod 105a-2 and the second push rod 105a-3 to descend, the connecting rod 105a-8 pushes the turntable 105a-6 to descend, and the second push rod 105a-3 pushes the block 105a-7 on the turntable 105a-6 to descend. However, the force exerted by the second push rod 105a-3 on the block 105a-7 not only has a downward force, but also has a clockwise force on the limit plate 105a-5 to the block 105a-7. Therefore, when the turntable 105a-6 pushes the sliding plate 105b-4 to descend, the sliding plate 105b-4 pushes the spring 105b-2 to descend to a height lower than the top of the block 105a-7. When the limiting plate 105a-5 is moved, the spring 105b-2 is reset to push the sliding plate 105b-4 to rise, and the turntable 105a-6 on the sliding plate 105b-4 pushes the connecting rod 105a-8, the first push rod 105a-2 and the second push rod 105a-3 to rise during the rising process. The connecting rod 105a-8 drives the extrusion block 105a-1 to rise. When the T-shaped limiting rod 105b-3 on the sliding plate 105b-4 slides to the top of the sliding hole on the fixed tube 105b-1, the extrusion block 105a-1 is limited, so that the extrusion block 105a-1 blocks the gap between the cover 101 and the placement shell 106. The advantage of this arrangement is to prevent dust from falling into the gap when the cover 101 is left stationary for a long time.
