Abstract
Description
Technical Field
[0001] This utility model belongs to the field of infusion pump technology, and specifically relates to an enteral nutrition infusion pump assembly. Background Technology
[0002] An enteral nutrition infusion pump is a device specifically designed for enteral nutrition support. It can deliver water, nutrient solutions, and homemade formula or milk of a specific concentration through a nasogastric tube. It features automatic infusion, infusion completion alarm, rapid drainage, and reverse axis functions. Improving the patient's nutritional status is a fundamental condition for disease treatment.
[0003] Currently, Chinese patent publication number CN221106480U, published on June 11, 2024, discloses an enteral nutrition infusion pump with automatic flushing capability. It includes a support rod, a fixing plate in the middle of the support rod, and two nutrition pumps on the top of the fixing plate. Each of the two nutrition pumps has a connector on one side of its end. The bottom of one connector is threaded to a nutrition tube, and the bottom of the other connector is threaded to a flushing tube. The end of the flushing tube is sealed and connected to one side of the nutrition tube.
[0004] This type of automatic flushing enteral nutrition infusion pump is supported on the ground by a support rod and a support plate. This results in the support rod and support plate occupying too much floor space in the ward, making the already cramped ward space even more crowded, which is not conducive to patient care and movement. Utility Model Content
[0005] The purpose of this invention is to provide an enteral nutrition infusion pump assembly that allows the pump body to be easily installed on a hospital bed.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an enteral nutrition infusion pump assembly, comprising a pump body, a nutrition bag, an infusion tube with one end connected to the nutrition bag and the other end passing through the pump body, and a base located on the back of the pump body, a column with its lower end connected to the base and extending vertically upward, wherein the upper end of the column is provided with multiple hooks for hanging the nutrition bag, and one side of the base is provided with a clamp arm with a "U"-shaped cross section for embedding into a bed rail, wherein a corrugated rubber block is provided on the inner wall of one side of the clamp arm. The side of the clamping arm away from the corrugated rubber block is provided with a first internal threaded sleeve communicating with the inside of the clamping arm. The first internal threaded sleeve is internally threaded to a first threaded shaft. The end of the first threaded shaft is provided with a first knob. The base is also provided with a spherical groove with an arc-shaped cross-sectional profile. The back of the pump body is provided with a connecting post extending toward one side of the base. The end of the connecting post away from the pump body is provided with a universal ball embedded in the spherical groove. The base is provided with a positioning component for positioning the universal ball in the spherical groove.
[0007] A further feature of this invention is that a connecting disc is provided at the end of the first threaded shaft away from the first knob, and a rubber disc is provided on the side of the connecting disc away from the first threaded shaft.
[0008] A further feature of this invention is that the positioning element includes a second internal threaded sleeve disposed on the upper side of the base and communicating with the spherical groove, and a threaded end disposed at the lower end of the column and threadedly connected to the second internal threaded sleeve.
[0009] A further feature of this invention is that a second knob is provided on the column.
[0010] A further feature of this invention is that a rotating shaft is provided on the outer wall of the middle part of the clamping arm, and a shaft hole for the rotating shaft to be inserted is provided in the base.
[0011] A further feature of this invention is that a third internal threaded sleeve communicating with the shaft hole is provided on the upper side of the base, a third threaded shaft is internally threaded to the third internal threaded sleeve, and a third knob is provided at the upper end of the third threaded shaft.
[0012] In summary, this utility model has the following beneficial effects:
[0013] 1. First, the pump body uses the locking arm on the base to insert the bed rail. Then, by rotating the first threaded shaft with the first knob, the first threaded shaft presses against the bed rail inside the locking arm. The bed rail is stably locked by the first threaded shaft and the corrugated rubber block. The nutrition bag can be hung using the column on the upper side of the base and the hook at the top of the column. At the same time, the pump body uses the universal ball at the end of the connecting column to be embedded in the spherical groove of the base. The positioning component is used to position the universal ball in the spherical groove, so that the angle of the pump body can be adjusted arbitrarily, and the information displayed on the pump body can be easily observed by medical staff. Finally, the pump body can be installed on the hospital bed in a relatively convenient way.
[0014] 2. A connecting plate is provided at the end of the first threaded shaft away from the first knob, and a rubber disc is provided on the side of the connecting plate away from the first threaded shaft. At this time, the first threaded shaft can be pressed against the bed rail by the connecting plate and the rubber disc, which can further facilitate the stable locking of the bed rail.
[0015] 3. The threaded end of the column is threaded into the second internal threaded sleeve. By rotating the column, the threaded end can be moved toward the spherical groove, thereby using the threaded end to press and position the universal ball.
[0016] 4. Using the second knob on the column, the column can be rotated easily and quickly;
[0017] 5. By utilizing the rotating shaft set on the outer wall of the middle part of the clamping arm, and the shaft hole opened in the base for the rotating shaft to be inserted, the angle of the clamping arm can be adjusted, so that the clamping arm can be clamped on different objects.
[0018] 6. The third threaded shaft can be rotated by the third knob, so that the end of the third threaded shaft is pressed against the rotating shaft, and finally the rotating clamp arm can be locked. Attached Figure Description
