In selecting the type of enteral nutrition infusion, factors such as the continuity of the patient's gastrointestinal anatomy, the integrity of the function, the expected time of enteral nutrition administration, the likelihood of aspiration, etc. need to be considered. The infusion of enteral nutrition can be categorized into oral nutritional supplements and tube feeding nutritional support, depending on the type of infusion. Oral nutritional supplementation is the first choice for enteral nutrition infusion, and is suitable for people with oral ingestion but insufficient intake, and is the safest, economical and physiological enteral nutrition support mode. Supplementing oral nutritional supplements on a dietary basis can improve nutritional status when a patient is at a nutritional risk/deficiency, without affecting dietary intake. Oral nutritional supplementation can reduce the nutritional risk and postoperative complications of bedridden patients. For example, oral nutritional supplements with higher protein content may reduce the risk of developing pressure sores.

If oral nutritional supplementation is not or is not sustained, tube feeding nutritional support should be considered. The tube feeding has the advantages that the tube feeding can ensure the even infusion of the nutrient solution and fully exert the digestion and absorption functions of the gastrointestinal tract. Common tube feeding routes are nasal feeding tubes and transdigestive tract ostomy tubes.

The monitoring device for enteral feeding pressure alarm (for convenience of description, infusion monitoring device for short) shown in connection with fig. 1 includes an infusion monitoring device housing 13. The infusion monitoring device housing 13 comprises a first cover plate 15 and a second cover plate 17 which are pivotably connected by a hinge 19, the first cover plate 15 and the second cover plate 17 being rotatable about the hinge 19 to open or close. The second cover 17 is of integrally formed construction. Preferably, the second cover 17 may be manufactured using conventional injection molding techniques.

The second cover plate 17 comprises a first radial lug 21 located radially outside and a first bottom surface 23 defined by the first radial lug 21. The first radial lug 21 is a cylindrical structure with two ends communicated, the cross section of the first radial lug 21 in the horizontal direction is ring-like, and at least one part of the ring of the first radial lug 21 protrudes for hinged connection with the first cover plate 15. Preferably, the first radial lug 21 and the first bottom surface 23 are integrally formed.

The first bottom surface 23 forms a first recess 25 with the annular inner wall of the first radial lug 21. A first circumferential wall 27 at the periphery of the first recess 25 is also formed under the definition of the recess. The peripheral side of the first peripheral wall 27 is provided with a locking mouth 28 which does not extend completely through the first radial lug, which locking mouth 28 serves to lockably retain the second cover plate 17 in its closed position, i.e. in a connected closed position with the first cover plate 15, as will be described in further detail below.

According to a preferred embodiment, the infusion monitoring device further comprises a cylindrical infusion tube connector 29, the infusion tube connector 29 being adapted to connect the interior space of the infusion monitoring device with a tube for transporting enteral nutrition. As shown in fig. 1, an infusion tube connector 29 extends orthogonally from the first bottom surface 23. The infusion tube connector 29 is sized and shaped to be inserted into the open end of a pre-cannula (e.g., into the open proximal end of an implanted gastrostomy feeding tube or into the input end of a Y port). Preferably, the infusion tube connector 29 includes outwardly projecting first 31 and second 32 flange rings spaced along its length. The first flange ring 31 and the second flange ring 32 are identical in shape and are each of an inverted conical configuration with an increasing cross-sectional area along the infusion tube connection 29 to the connection end with the first bottom surface 23. The first flange ring 31 and the second flange ring 32 enable the infusion tube connector 29 to be inserted into the inner surface of the pre-cannula and to remain fixedly connected to the pre-cannula. In this way, the first flange ring 31 and the second flange ring 32 are able to fix the infusion tube connector 29 of the infusion monitoring device within the pre-cannula. The infusion tube connector 29 is a simple body of a structure having a cylindrical tube connector inner passage 33 provided therein.

According to a preferred embodiment, the first cover plate 15 is preferably a unitary member that can be manufactured using conventional injection molding techniques. The first cover plate 15 is similar in structure to the second cover plate 17. The first cover plate 15 comprises a second radial lug 39 located radially outside and a second bottom surface 41 defined by the second radial lug 39. The second circumferential wall 43 protrudes from the second bottom surface 41. As the first cover plate 15 is pivoted to its closed position, the protruding second circumferential wall 43 can be nested in the first recess 25. The second circumferential wall 43 is frictionally engaged with the inner surface of the first circumferential wall 27 on its circumferential side. The friction between the second circumferential wall 43 and the first circumferential wall 27 can be such that the first cover plate 15 and the second cover plate 17 are connected in a closed position, further maintaining the sealed environment of the first recess 25. As shown in fig. 1, the protruding portion 45 protrudes vertically from the inside of the second bottom surface 41. As the first cover plate 15 is pivoted to the closed position, the protrusions 45 are interference-connected into the pipe joint inner passages 33, and the protrusions 45 can be sealingly engaged between the pipe joint inner passages 33. With the first cover plate 15 pivoted closed, gastric or intestinal contents from within the patient cannot flow out of the tube fitting interior channel 33 through the pre-cannula.

The latch arms 53 extend perpendicularly from the second bottom surface 41 peripheral side of the first cover plate 15. The end of latch arm 53 is provided with a shoulder 55. The shoulder 55 extends inwardly perpendicular to the latch arms 53. The dimensional fit of the shoulder 55 can protrude into the locking aperture 28 in the second cover plate 17 when the first cover plate 15 is in the closed position so that the first and second cover plates 15, 17 can be retained by the locking member 47 and the locking aperture 28 when in the closed position. As shown in fig. 3, the drivable member 51 includes a tab 57. The tab 57 nests on the outer edge of the first cover plate. The two sides of tab 57 that connect to first cover panel 15 are defined by score lines 59. Preferably, the tab 57 has an oval recess 61 in the outer ledge. Recess 61 is sized and shaped to receive a finger in an ergonomic shape, and score line 59 is provided to allow for displacement deflection of tab 57 when recess 61 is subjected to top-to-bottom pressure. Specifically, when the shoulder 55 extends into the locking aperture 28 to lock the first and second cover panels 15, 17 in their closed positions, external pressure on the recess 61 will cause the inner end of the tab 57 to move inwardly, during which the shoulder 55 of the L-shaped latch 49 moves outwardly. When the L-shaped latch 49 is moved outwardly, the shoulder 55 will withdraw from the locking aperture 28, unlocking the first and second cover panels 15, 17, at which point the first and second cover panels 15, 17 can be pivoted to an open position by the hinge.

The pressure sensitive material is electrically connected to the control mechanism 63 such that fluid passing through the passageway 33 in the coupler is in turn sensed by the piezo-resistor of the metering assembly 71. At this point, metering assembly 71 is capable of transmitting an electrical signal to control mechanism 63 in response to detecting fluid passing through passageway 33 within the tube fitting, which signal is capable of determining the amount of fluid dispensed and ultimately fed into the patient. The display assembly 75 is electrically connected to the control mechanism 63 and visually presents the relevant data collected within the storage assembly. The display assembly 75 is represented herein in the form of an LED liquid crystal display screen capable of displaying numeric and/or alphabetic characters.
