Description

Technical Field

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

[0002] As the trend of population aging intensifies, the "silver economy" is booming, and at the same time, there is a more urgent need for innovation in products that are suitable for the elderly. Taking medical devices as an example, the "silver group" has a wide range of needs in health management, but due to factors such as physical function decline, weakened digestive function, and weakened cognitive function, it is difficult to fully and effectively utilize them. Therefore, enteral feeding devices are needed to assist in daily feeding life.

[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 the 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 end position to restrict the flow of the nutrient solution, the roller moves backward a large amount; 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 an uneven flow rate of the nutrient solution and an intermittent situation. This abnormal titration feeding process; whether the flow rate is faster or uneven, it will cause serious health problems for frail patients and may even be life-threatening. Summary of the invention

[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 object of the invention, a technical solution provided by the present invention is as follows: A feeder adjustment device includes a shell and a roller, wherein the shell has a bottom wall and side walls located on both sides of the bottom wall, and both ends of the roller are slidably connected to the corresponding side walls so that the roller can move forward and backward along the side walls, and the moving direction is inclined relative to the bottom wall. A groove is provided on a side of the bottom wall corresponding to the roller along the length direction of the shell.

DETAILED DESCRIPTION

[0016] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0017] For examples, see Figure 1 and Figure 2 The present embodiment provides a feeder adjustment device, comprising a housing 1 and a roller 2, wherein the housing has a bottom wall 1-1 and side walls 1-2 located on both sides of the bottom wall, and both ends of the roller are slidably connected to the corresponding side walls so that the roller can move forward and backward along the side walls. For ease of understanding, the applicant Figure 1 The front and rear position directions are schematically marked with arrows, wherein 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, in actual production, it can be seen that a groove inclined relative to the bottom wall is provided on the side wall, and both 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 a groove 1-3 is 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).

[0018] 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. The adjustment accuracy is higher, and it is not easy for the nutrient solution to flow too fast, the flow rate to be uneven or intermittent during adjustment.

[0019] In one embodiment, a first anti-skid tooth 1-4 is provided on one side of the bottom wall corresponding to the roller, and the first anti-skid tooth is provided close to the front end of the housing; a second anti-skid tooth 2-1 matching the first anti-skid tooth is provided circumferentially on the roller. This structure increases the friction and squeezing degree between the roller and the nutrient solution guide tube through the first anti-skid tooth and the second anti-skid tooth when the roller moves to the position of the first anti-skid tooth, making it easy to cut off the supply of nutrient solution and facilitate the operation of the feeder before and after use.

[0020] In one embodiment, see Figure 3 and Figure 4 A cover plate 1-5 is slidably arranged on the groove, and a side of the cover plate facing away from the groove is flush with a 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: Mode of use 1: When the cover is slid to a position close to the rear end of the shell, it is used to adjust the flow rate of the nutrient solution. The adjustment principle has been described above and will not be repeated here. Usage mode 2, when the cover plate is slid to a position close to the front end of the shell, it is applied to the state before and after the nutrient solution is supplied. At this time, the roller is located at the front end of the shell, squeezing the nutrient solution guide tube and then squeezing the cover plate. The cover plate remains stationary with the side wall or bottom wall by friction. At this time, the position of the nutrient solution guide tube relative to the roller 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 the supply; Method of use 3 is applied to the regulation of the nutrient solution supply flow rate. 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 position where it contacts the cover plate is slightly deformed, thereby preventing the nutrient solution guide tube from being reduced in pressure as a whole, and the regulation accuracy is higher. During this process, the cover plate remains stationary with the side wall or the 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 position where it contacts the cover plate is slightly deformed less, thereby preventing the nutrient solution guide tube from being increased in pressure as a whole, and the regulation accuracy is higher. During this process, the cover plate remains stationary with the side wall or the bottom wall by friction. 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 regulating device to be used for flow regulation of clear and dilute liquids such as sodium chloride solution and glucose solution.

[0021] It should be noted that the grooves in the above embodiment may not be set on the bottom wall, but directly on the side wall. Of course, grooves may be set on both the bottom wall and the side wall. When grooves are set on both, the width of the groove on the bottom wall may be less than half of the width of the bottom wall. When grooves are set on the side wall, the grooves need to be set at the position where the side wall and the bottom wall are connected to facilitate the roller to squeeze the nutrient solution guide tube. Of course, a cover plate structure may also be provided, which is something that a person skilled in the art can easily think of based on the above embodiment, and will not be repeated here. It should be noted that the phrases "one embodiment", "an embodiment", "an exemplary embodiment", "some embodiments", etc. mentioned in the specification indicate that the described embodiments may include certain features, structures or characteristics, but not every embodiment may include the certain features, structures or characteristics. In addition, such phrases do not necessarily refer to the same embodiment. In addition, when describing certain features, structures or characteristics in conjunction with an embodiment, it is within the knowledge of those skilled in the art to implement such features, structures or characteristics in conjunction with other embodiments, whether explicitly or not explicitly described.

[0022] It should be easily understood that “on,” “above,” and “over” in the present disclosure should be interpreted in the broadest manner, so that “on” not only means “directly on something,” but also includes the meaning of “on something” with intervening features or layers therebetween, and “above” or “over” not only includes the meaning of “above” or “over,” but also may include the meaning of “above” or “over something” with no intervening features or layers therebetween (i.e., directly on something).
