Description

Technical Field

[0001] The invention relates to the field of enteral nutrition equipment, in particular to a cleanable self-drip bag for nutrient solution. Background Art

[0002] Improving a patient's nutritional status is fundamental to disease treatment. Clinical nutrition is divided into enteral and parenteral nutrition. Enteral nutrition is more conducive to the body's physiological nutrient metabolism and utilization. It can safely and effectively promote and maintain intact gastrointestinal structure and function, protect the gastric mucosal barrier, and reduce complications. It is safer and more effective than parenteral nutrition, not only reducing treatment costs but also making complications relatively easier to manage. An enteral nutrition pump is a nutritional infusion pump suitable for nasogastric feeding. It can deliver water, nutrient solution, and homemade rice milk of a certain concentration through a nasogastric tube. It features automatic infusion, end-of-infusion alarm, rapid discharge, and reverse axis functions.

[0003] At present, enteral nutrition faces the following difficulties in actual operation: 1. Since the nasogastric feeding process is intermittent, during a short stay, the tube often needs to be flushed for the next nasogastric feeding. The flushing process requires real-time care from medical staff, which requires a high number of hospital staff. At the same time, nasogastric feeding patients can often only express themselves with body language, and care is delayed; 2. The nutrient solution for enteral nutrition faces the problem of gelatinization and cannot have its own heat source, but too low a temperature will irritate the patient's gastrointestinal tract.

[0004] In summary, the current technology has problems such as low degree of automation, complicated steps, difficult cleaning, and low patient comfort. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems of low automation, complicated steps, difficult cleaning and low patient comfort in the prior art.

[0006] The specific scheme of the present invention is:

[0007] A cleanable self-drip bag for nutrient solution is designed, comprising a nutrient solution bag and a cleaning bag hung on the nutrient solution bag. The cleaning bag is filled with physiological saline. The cleaning bag is provided with two liquid outlets, one of which is connected to a cleaning bag branch via a parallel branch, and a selective switch mechanism is provided at the connection. The other liquid outlet is at the liquid outlet of the nutrient solution, and a float-type one-way valve is provided at the outlet of the pipeline. Liquid injection ports are provided on the cleaning bag and the nutrient solution bag, and a warning line is drawn above the position of the top of the float.

[0008] In a specific implementation, the selective switch mechanism includes a box body, in which a Y-shaped tube is placed, the double ends of the Y-shaped tube are respectively connected to the nutrient solution bag and the cleaning bag, the single end of the Y-shaped tube is connected to the outlet of the drip bag, and a cam-type shift block is provided between the double ends of the Y-shaped tube, and a central rotating shaft is provided at the axis center of the short axis end of the cam-type shift block, and the central rotating shaft is externally connected to a rocker.

[0009] Alternatively, the central shaft may be replaced with an external bidirectional micro motor as a power source.

[0010] In a specific implementation, the float-type one-way valve includes a conical bucket-shaped shell located inside the liquid outlet of the cleaning bag, the edge of the conical bucket-shaped shell is provided with a serrated liquid flow port, and the interior of the conical bucket-shaped shell is provided with a float. The float is tangent to the conical bucket-shaped shell when in a floating state.

[0011] In a specific implementation, the side of the nutrient solution bag is Y-shaped, the cleaning bag is mounted at the inflection point, and hanging hooks are provided on the nutrient solution bag and the cleaning bag. The hanging hooks of the nutrient solution bag are installed at the center of the outer surface of the nutrient solution.

[0012] Alternatively, the hanging hook point of the nutrient solution bag is replaced to be lower than 2 / 3 of the height of the nutrient solution bag.

[0013] In a specific implementation, the cleaning bag is provided with a heat-insulating bag for controlling the temperature inside the cleaning bag to be less than 30 degrees.

[0014] In a specific implementation, the heat-generating insulation bag includes a bottom positioning plate, a claw installed on the bottom positioning plate, and a heating plate installed on the claw. A through hole is provided on the positioning plate, and the claw is nested in the through hole to maintain freedom in the vertical direction. A dovetail groove connection is provided between the heating plate and the claw.

[0015] The rocker is connected to a locking mechanism, which includes a return spring installed on the central shaft and a movable positioning pin inserted into the rocker and the box paper.

[0016] The beneficial effects of the present invention are:

[0017] Intermittent flushing is achieved through parallel pipes, and the final flushing is achieved through the internal one-way valve design, with fewer electric components and a high degree of automation;

[0018] The height and position of each component are designed reasonably, and the user can operate it by simply extending the left arm, reducing the need for medical staff;

[0019] Appropriate insulation measures can achieve continuous low-temperature external heating, which not only ensures the temperature but also prevents the nutrient solution from gelatinizing under temperature conditions; the flexibility of the material is utilized, and the fixed point design facilitates the stability of the nutrient solution bag after the nutrient solution is poured.

[0027] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. Example 1

[0028] A cleanable self-drip bag for nutrient solution, see Figures 1 to 6 The design includes a nutrient solution bag 1 and a cleaning bag 2 hung on the nutrient solution bag 1. The cleaning bag is filled with physiological saline. The cleaning bag 2 is provided with two liquid outlets, one of which is connected to the cleaning bag branch 3 via a parallel branch. A switch mechanism is provided at the connection. The other liquid outlet is at the outlet of the nutrient solution. At the same time, a float-type one-way valve is provided at the outlet of the pipeline. Liquid injection ports are provided on the cleaning bag 2 and the nutrient solution bag 1. During operation, first connect the various pipelines, then open and inject the nutrient solution, and take a break at the same time. During the feeding process of flushing the tube, the cleaning bag is disposable, but during a single feeding, the whole can start injecting and flushing back and forth. The liquid injection port of the nutrient solution can also be used for temporary rehydration, as long as it is above the warning line and does not affect the lifting of the float.

[0029] The selective switch mechanism includes a box body 5, in which a Y-shaped tube is placed. The double ends of the Y-shaped tube are respectively connected to the nutrient solution bag 1 and the cleaning bag 2, and the single end of the Y-shaped tube is connected to the outlet of the drip bag. A cam-type shift block 6 is provided between the double ends of the Y-shaped tube, and a central rotating shaft is provided at the axis center of the short axis end of the cam-type shift block 6, and the central rotating shaft is externally connected to a rocker 7.

[0030] The float-type one-way valve comprises a conical bucket-shaped housing 8 located below the liquid outlet of the cleaning bag 2. The edge of the conical bucket-shaped housing 8 is provided with a serrated liquid flow port. A float 4 is located within the conical bucket-shaped housing 8. When the float 4 is in the floating position, it is tangential to the conical bucket-shaped housing 8. When the liquid in the nutrient solution bag is depleted, the float drops, completing the final flushing step. The liquid flow port ensures the flow of liquid inside and outside the conical bucket-shaped housing.

[0031] The side of the nutrient solution bag 1 is Y-shaped, and the cleaning bag 2 is clamped at the inflection point. The nutrient solution bag 1 and the cleaning bag 2 are also provided with hanging hooks, and the hanging hook of the nutrient solution bag 1 is installed at the center of the outer surface of the nutrient solution.

[0032] The cleaning bag 2 is provided with a heat-insulating bag that controls the temperature inside the cleaning bag 2 to be less than 30 degrees. The heating method is gentle and slow, which is suitable for the use environment of this embodiment.

[0033] The heat-generating insulation bag includes a bottom positioning plate, a claw 9 installed on the bottom positioning plate, and a heating plate 10 installed on the claw 9. A through hole is provided on the positioning plate, and the claw 9 is nested in the through hole to maintain freedom in the vertical direction. A dovetail groove connection is provided between the heating plate 10 and the claw 9.

[0034] The rocker 7 is connected to a locking mechanism, which includes a return spring mounted on the central shaft and a movable positioning pin 12 inserted between the rocker 7 and the paper piece of the box body 5. Steering is achieved by shaking, and when the force is unloaded, the return spring achieves steering. Example 2

[0035] The principles of this embodiment are similar to those of Example 1, with the specific difference being that the hook point for the nutrient solution bag 1 is lower than two-thirds of the bag's height. This facilitates deformation and overall stability when the nutrient solution bag 1 is depleted of liquid. During deformation, the two wings flip toward the center, stabilizing the overall center of gravity. This also facilitates passing medical personnel in observing the remaining capacity. Example 3

[0036] The principles of this embodiment are similar to those of Example 1, with the specific difference being that the central shaft is replaced with an externally connected bidirectional micromotor as the power source. Through circuit control, the work of medical staff is further streamlined. During operation, the motor can also be connected to a time relay to control the steering time and ensure intermittent flushing. Intermittent flushing can ensure that patients achieve balanced absorption of the nutrient solution through small amounts and multiple doses. It can also be achieved by adding a drug to the cleaning liquid bag to alleviate gastric irritation, thereby alleviating gastrointestinal discomfort after nasogastric feeding.

[0037] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
