[0026] The present invention is further described with reference to the accompanying drawings and embodiments:

[0027] Embodiment 1:

[0028] This embodiment provides the following Figure 1-4 A medical liquid food feeder is shown, which includes a feeding tube 1 and an adjusting pull tab 2; the interior of the feeding tube 1 is a hollow structure, an opening 3 is provided at one end of the feeding tube 1, a groove 4 is provided on the side of the opening 3, a feeding port 5 is provided on the side of the other end of the feeding tube 1, one end of the adjusting pull tab 2 is slidably provided in the feeding tube 1, the other end of the adjusting pull tab 2 extends out, and a handshake portion 21 is provided on the other end of the adjusting pull tab 2.

[0029] In this embodiment, the feeding tube 1 is used to inject liquid food; the adjusting pull tab 2 is used to adjust the size of the feeding port 5, thereby adjusting the flow rate and speed of the liquid food; an opening 3 is provided at one end of the feeding tube 1, where liquid food can be injected, and the other end is closed, and a feeding port 5 is provided on one side. When in use, the lower part of the feeding port 5 faces the esophagus, which can alleviate the patient's discomfort. One end of the adjusting pull tab 2 is slidably arranged in contact with the feeding port 5, and the other end extends and is provided with a gripping portion 21. By pushing and pulling the gripping portion 21, the adjusting pull tab 2 is adjusted to penetrate the feeding tube 1, thereby adjusting the shielding area of ​​the other end of the adjusting pull tab 2 at the feeding port 5. When the adjusting pull tab 2 is pulled outward, the area of ​​the feeding port 5 gradually increases, and the flow rate and speed increase accordingly. When the adjusting pull tab 2 is pushed inward, the area of ​​the feeding port 5 gradually decreases, and the flow rate and speed also decrease accordingly. This operation is simple, saves more effort than the push-type, and can also be operated with one hand. The groove 4 is provided to realize the movement of the grip portion 21 as the adjusting pull tab 2 is extended, and also to limit the penetration length of the adjusting pull tab 2.

[0030] Embodiment 2:

[0031] This embodiment provides the following Figure 1-4 A medical liquid food feeder is shown, which includes a feeding tube 1 and an adjusting pull tab 2; the interior of the feeding tube 1 is a hollow structure, an opening 3 is provided at one end of the feeding tube 1, a groove 4 is provided on the side of the opening 3, a feeding port 5 is provided on the side of the other end of the feeding tube 1, one end of the adjusting pull tab 2 is slidably provided in the feeding tube 1, the other end of the adjusting pull tab 2 extends out, and a handshake portion 21 is provided on the other end of the adjusting pull tab 2.

[0032] This embodiment is based on the first embodiment. Further, in order to ensure that the adjustment tab 2 can be stably pulled out and inserted into the feeding tube 1, the inner wall diameter of the feeding tube 1 is gradually reduced from the opening 3 to the feeding port 5. The adjustment tab 2 is arranged to fit the inner wall of the feeding tube 1, and the adjustment tab 2 is rolled up in a circular shape along the feeding tube 1.

[0033] Through the above arrangement, during use, when the adjusting pull tab 2 is pushed into the feeding tube 1, the adjusting pull tab 2 is rolled up in a circular shape along the feeding tube 1, so as the inner wall of the feeding tube 1 gradually decreases, the rolling force of the adjusting pull tab 2 is gradually increased, and then the diameter of the adjusting pull tab 2 is gradually reduced; on the contrary, when the adjusting pull tab 2 is pulled out from the feeding tube 1, the inner wall of the feeding tube 1 increases, so the rolling force of the adjusting pull tab 2 is gradually reduced, and then the adjusting pull tab 2 is gradually relaxed, and its diameter is gradually increased. That is, in the above process, whether the adjusting pull tab 2 is pushed in or pulled out, it moves closely against the inner wall of the feeding tube 1, so as to prevent the adjusting pull tab 2 from loosening and ensure the stability of the movement process.

[0034] Further, in order to ensure the feasibility of the movement of the gripping portion 21 in the groove 4, as shown in the attached Figure 1 As shown, the width of the gripping portion 21 is less than or equal to the width of the groove 4 .

[0035] Furthermore, in this embodiment, the feeding tube 1 and the adjusting pull tab 2 are both made of plastic material.

[0036] Furthermore, in actual use of this embodiment, the feeder is a disposable item.

[0037] In actual use, the opening 3 of the feeding tube 1 can be connected to a food bag containing liquid food through a hose or the like, so as to receive the liquid food.

[0038] Furthermore, a scale is provided on the adjusting pull tab 2. The feeding tube 1 is made of a transparent material, which can be observed intuitively during use, and is convenient for the user to control the amount and speed.

[0039] Furthermore, the length of the feeding tube is 6 cm, and the minimum diameter of the feeding tube is 1 cm.

[0040] Furthermore, the size of the groove is 2*1 cm, that is, the length of the groove is 2 cm and the width is 1 cm.

[0041] Embodiment three:

[0042] This embodiment provides the following Figure 1-8A medical liquid food feeder is shown, which includes a feeding tube 1 and an adjusting pull tab 2; the interior of the feeding tube 1 is a hollow structure, an opening 3 is provided at one end of the feeding tube 1, a groove 4 is provided on the side of the opening 3, a feeding port 5 is provided on the side of the other end of the feeding tube 1, one end of the adjusting pull tab 2 is slidably provided in the feeding tube 1, the other end of the adjusting pull tab 2 extends out, and a handshake portion 21 is provided on the other end of the adjusting pull tab 2.

[0043] This embodiment is based on the second embodiment, in order to further facilitate the use of the feeding tube 1, as shown in the attached Figure 5-8 As shown, in this embodiment, it also includes an injection tube 6, which is a hollow through structure. One end of the injection tube 6 is connected to the opening 3 of the feeding tube 1, and the other end of the injection tube 6 is provided with a push rod 9, one end of which is slidably disposed inside the injection tube 6.

[0044] The injection tube 6 is used to improve the convenience of using the feeding tube 1. The inside of the injection tube 6 is a hollow through structure, and one end is connected to the feeding tube 1. The user can push and pull the push rod 9 at the other end to suck and inject the liquid food. When in use, the liquid food can be sucked through the injection tube 6 first, and then installed with the feeding tube 1, and then the push rod 9 can be used to further push the liquid food into the feeding tube 1, and then the flow rate of the liquid food can be adjusted by adjusting the pull tab 2. At this time, the user can easily operate with one hand.

[0045] In order to connect the feeding tube 1 and the injection tube 6, as shown in the attached Figure 5 As shown, one end of the injection tube 6 is provided with a mounting structure 7, and the diameter of the mounting structure 7 is smaller than the inner wall diameter of one end of the feeding tube 1. During installation, the annular structure of the mounting structure 7 is arranged to fit the inner wall of the opening 3 of the feeding tube 1 to achieve stable installation.

[0046] Further, in order to ensure that after the injection tube 6 is installed, the pull tab 2 can still be pushed and pulled, as shown in the attached Figure 5-8 As shown, one end of the injection tube 6 is provided with a slide groove 8 corresponding to the groove 4. The slide groove 8 is located below the adjustment pull tab 2. After installation, the slide groove 8 and the groove 4 are combined to form a space for the adjustment pull tab 2 to move, so that the adjustment pull tab 2 can achieve push-pull movement to change the size of the feeding port 5. At the same time, the slide groove 8 can isolate the internal space to prevent the liquid food from leaking out of the groove.

[0047] Furthermore, the body of the injection tube is provided with a scale, which can help the user observe the amount of injection and thus adjust the strength of the injection.

[0048] The main function of the utility model is to be applied to various medical instruments, especially feeders used for patients with difficulty in eating, and to control the flow rate and speed of liquid food more labor-savingly and stably by changing the size of the feeding opening by adjusting the pull tab accordingly.
