Description

Technical Field

[0001] The utility model relates to the technical field of intestinal drug nutrition feeding, in particular to a feeder regulating device. Background Art

[0002] As the aging population intensifies, the "silver economy" is experiencing rapid growth, creating a more pressing need for innovative, age-friendly products. Taking medical devices as an example, the "silver age group" has extensive health management needs, but due to factors such as declining physical function, weakened digestive function, and decreased cognitive function, they struggle to fully utilize them effectively. Therefore, enteral feeders are needed to assist with daily feeding.

[0003] The flow regulator in a conventional infusion pump is made for clear and thin liquids such as sodium chloride solution and glucose solution. When using this flow regulator to adjust to nutrient solution, since the nutrient solution is relatively viscous, the roller movement position is not easy to adjust during the adjustment process. When the roller is at the front position to restrict the flow of the nutrient solution, the roller moves backward more; the nutrient solution flow rate is faster; when the roller moves to a small flow state, the nutrient solution cannot easily overcome the adhesion of the nutrient solution to the flow channel by relying solely on its own gravity, resulting in uneven nutrient solution flow rate and intermittent setting. This abnormal titration feeding process; whether the flow rate is faster or uneven, it will bring serious health problems to weak patients, and may even be life-threatening. Utility Model Content

[0004] In view of the problems existing in the above-mentioned prior art, the present invention provides a feeder adjustment device to solve at least one of the above-mentioned technical problems.

[0005] In order to achieve the above-mentioned purpose of the utility model, a technical solution provided by the utility model is as follows:

[0006] A feeder adjustment device includes a shell and a roller. The shell has a bottom wall and side walls located on both sides of the bottom wall.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] For examples, see Figure 1 and Figure 2 This embodiment provides a feeder adjustment device, including a housing 1 and a roller 2. The housing has a bottom wall 1-1 and side walls 1-2 located on both sides of the bottom wall. The two ends of the roller are slidably connected to the corresponding side walls, so that the roller can move back and forth along the side walls. For ease of understanding, the applicant Figure 1 The front and rear position directions are schematically marked with arrows, where the front and rear direction can also be said to be the length direction of the shell, and the moving direction is inclined relative to the bottom wall. Generally, during actual production, it can be seen that a groove inclined relative to the bottom wall is provided on the side wall, and the two ends of the roller are located in the inclined groove. These trivial matters are well known to those skilled in the art and are not specifically limited here. The improved position of this embodiment is mainly that grooves 1-3 are provided on a side of the bottom wall corresponding to the roller along the length direction of the shell (it can also be said to be the front and rear direction of the shell).

[0024] The above-mentioned feeder adjustment device is provided with a groove. When the roller moves to squeeze the nutrient solution guide tube, part of the nutrient solution guide tube enters the groove to form a liquid flow channel. When the roller moves forward or backward, the deformation degree of the part of the nutrient solution guide tube outside the groove is adjusted, and the adjustment accuracy is higher. It is not easy for the nutrient solution to flow too fast, the flow rate to be uneven or intermittent during adjustment.

[0025] In one embodiment, the bottom wall is provided with first anti-slip teeth 1-4 on a side corresponding to the roller, located near the front end of the housing. Second anti-slip teeth 2-1 are circumferentially disposed on the roller to match the first anti-slip teeth. This structure increases friction and compression between the roller and the nutrient solution guide tube when the roller moves to the position of the first anti-slip teeth, utilizing the first and second anti-slip teeth to facilitate shutoff of the nutrient solution supply and facilitate operation of the feeder before and after use.

[0026] In one embodiment, see Figure 3 and Figure 4A cover plate 1-5 is slidably provided on the groove, and the side of the cover plate facing away from the groove is flush with the side of the bottom wall corresponding to the roller; the length of the cover plate is less than the length of the groove. Generally, the length of the cover plate is about one-quarter of the length of the groove. The feeder adjustment device of this structure has the following usage:

[0027] Mode 1: When the cover is slid to the rear end of the housing, it is used to adjust the flow of the nutrient solution. The adjustment principle has been described above and will not be repeated here.

[0028] Usage mode 2: When the cover is slid to a position close to the front end of the housing, it is used before and after the nutrient solution is supplied. At this time, the roller is located at the front end of the housing, squeezing the nutrient solution guide tube and then squeezing the cover. The cover is kept stationary by friction with the side wall or bottom wall. At this time, the position where the nutrient solution guide tube and the roller are opposite cannot be partially squeezed into the groove and is completely squeezed and deformed, thereby ensuring that the nutrient solution will not leak before and after supply.

[0029] The third method of use is used to adjust the flow rate of nutrient solution supply. The cover plate is slid to a position close to the roller and located behind the roller position, so that the part of the nutrient solution guide tube close to the roller behind the roller position is slightly deformed by the roller, but the nutrient solution road tube under the roller can still be squeezed into the groove at the front end of the cover plate to maintain the supply of nutrient solution. In this way, when the roller moves backward, the contact part of the nutrient solution guide tube with the bottom wall is squeezed less and the contact part with the cover plate is slightly deformed, thereby preventing the nutrient solution guide tube from being pressurized as a whole, and achieving higher adjustment accuracy. During this process, the cover plate is kept stationary against the side wall or bottom wall by friction. Similarly, when the roller moves forward, the contact part of the nutrient solution guide tube with the bottom wall is squeezed more and the contact part with the cover plate is slightly deformed less, thereby preventing the nutrient solution guide tube from being pressurized as a whole, and achieving higher adjustment accuracy. During this process, the cover plate is kept stationary against the side wall or bottom wall by friction.

[0030] Usage method 4 is applied to conventional infusion pumps. The middle part of the cover is moved directly to the bottom of the roller so that the cover and the bottom wall are flush, preventing the infusion pump guide tube from entering the groove relative to the roller. This allows the adjustment device to be used for flow regulation of clear and thin liquids such as sodium chloride solution and glucose solution.

[0031] It should be noted that the grooves in the above embodiment may not be set on the bottom wall, but directly on the side walls. Of course, grooves can also be set on both the bottom wall and the side walls. When grooves are set on both, the width of the groove on the bottom wall can be less than half of the width of the bottom wall. When grooves are set on the side walls, the grooves need to be set at the position where the side walls connect with the bottom wall to facilitate the roller to squeeze the nutrient solution guide tube. Of course, a cover plate structure can also be set. This is something that those skilled in the art can easily think of based on the above embodiments, and will not be repeated here.

[0032] It should be noted that references in this specification to "one embodiment," "an embodiment," "an exemplary embodiment," "some embodiments," and the like indicate that the described embodiment may include a particular feature, structure, or characteristic, but not necessarily every embodiment includes that particular feature, structure, or characteristic. Furthermore, such phrases do not necessarily refer to the same embodiment. Furthermore, when a particular feature, structure, or characteristic is described in conjunction with an embodiment, it is within the knowledge of those skilled in the art to implement such feature, structure, or characteristic in conjunction with other embodiments, whether explicitly described or not.

[0033] It should be readily understood that “on,” “above,” and “over” in this disclosure should be interpreted in the broadest manner, such that “on” means not only “directly on something,” but also includes “on something” with intervening features or layers therebetween, and “above” or “over” includes not only the meaning of “above” or “over,” but also includes “above” or “over” with no intervening features or layers therebetween (i.e., directly on something).

[0034] Additionally, spatially relative terms, such as "below," "beneath," "beneath," "above," and the like, may be used herein for ease of description to describe the relationship of one element or feature to other elements or features as depicted in the figures. Spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures.
