Description

Technical Field

[0001] The invention belongs to the field of medical equipment, and in particular relates to an enteral nutrition pump device. Background Art

[0002] An enteral nutrition pump is a medical device used to deliver nutrients directly to the gastrointestinal tract. It is mainly used for patients who cannot take in enough nutrients through normal diet, especially when the digestive system is damaged or incomplete. The main functions include:

[0003] 1. Providing nutrition: Through this device, liquid nutrients (such as nutrient solution) can be continuously or regularly delivered to the patient's gastrointestinal tract to meet their daily nutritional needs.

[0004] 2. Ensure nutritional intake: For patients who are unable to eat normally due to illness, surgery or other reasons, enteral nutrition pumps can ensure that they get enough energy and nutrition to maintain good health.

[0005] 3. Improve the quality of life: By providing stable nutritional support, patients can reduce health problems caused by malnutrition and improve their overall health and quality of life.

[0006] 4. Adjust the nutritional formula: The formula of the nutrient solution can be adjusted according to the patient's specific situation to meet different nutritional needs.

[0007] Most of the enteral nutrition pump devices in the prior art do not have the function of automatic dilution and need to be manually diluted, which causes the patient to easily get blocked or feel uncomfortable during the process of feeding the nutrient solution. At the same time, the enteral nutrition pump devices in the prior art do not have the function of automatically processing nutrient raw materials and need to be manually prepared, which increases the workload of medical staff. To this end, we provide an enteral nutrition pump device to solve the above problems. Summary of the invention

[0008] The object of the present invention is to provide an enteral nutrition pump device, which solves the problem that most of the enteral nutrition pump devices in the prior art do not have automatic dilution and automatic processing through the cooperation of a water supply component and a processing component.

[0009] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0010] An enteral nutrition pump device comprises an enteral nutrition pump body 1, a liquid infusion tube 2 is provided through one side of the inner cavity of the enteral nutrition pump body 1, a water tank 3 is fixedly connected to the top of the enteral nutrition pump body 1, a heater 4 is fixedly connected to one side of the water tank 3, a heating pipe of the heater 4 extends to the inside of the water tank 3, and a medicine injection tank 5 is provided on one side of the enteral nutrition pump body 1;

[0011] A water supply assembly is provided on one side of the water tank 3, and the water supply assembly includes a pulse pump 6, the pulse pump 6 is connected to one side of the water tank 3, the other side of the pulse pump 6 is connected to a pulse tube 7, the other end of the pulse tube 7 is connected to the infusion tube 2, one side of the pulse tube 7 is connected to a first shunt tube 8, the other end of the first shunt tube 8 is connected to the injection tank 5;

[0012] A processing assembly is arranged inside the medicine injection tank 5, and the processing assembly includes a motor 9. The output end of the motor 9 extends into the medicine injection tank 5 and is fixedly connected to a stirring rod 10. A medicine injection tube 11 is connected to the top of one side of the medicine injection tank 5, and a medicine outlet tube 12 is connected to the bottom of the medicine injection tank 5. A second shunt tube 13 is connected to one side of the surface of the medicine outlet tube 12, and the other end of the second shunt tube 13 is connected to the infusion tube 2.

[0013] A mounting assembly is also provided on one side of the enteral nutrition pump body 1, and the mounting assembly includes a mounting plate 14, a slide groove is provided inside the mounting plate 14, and a fixing plate 15 is slidably connected inside the slide groove. The fixing plate 15 is sleeved on the surface of the medicine injection tank 5 and fixedly connected to the medicine injection tank 5.

[0014] The top sides of the mounting plate 14 are both threadedly connected with limit pins 16 , and the bottom of the limit pins 16 penetrates the mounting plate 14 and extends to the inside of the fixing plate 15 .

[0015] A positioning frame 17 is fixedly connected to the top and bottom of the back side of the enteral nutrition pump body 1 , and a positioning pin 18 is threadedly connected to one side of the positioning frame 17 .

[0016] The surface of the first shunt pipe 8 is connected to a first control valve 19 , the surface of the second shunt pipe 13 is connected to a second control valve 20 , and the surface of the medicine outlet pipe 12 is connected to a third control valve 21 .

[0017] A support plate is fixedly connected to the bottom of the pulse pump 6 , and the bottom of the support plate is fixedly connected to one side of the top of the enteral nutrition pump body 1 .

[0018] By setting the mounting plate 14, the slide groove, the fixing plate 15 and the limit pin 16, the medicine injection tank 5 can be quickly disassembled and assembled, so that the medicine injection tank 5 and the enteral nutrition pump body 1 are designed as a separate body, so that medical staff can choose whether to use the medicine injection tank 5, thereby improving the convenience of using the medicine injection tank 5. By setting the positioning frame 17 and the positioning pin 18, the device can be fixed on the infusion pole to facilitate normal use of the device.

[0019] When it is necessary to mix multiple nutrient solutions, first pour the multiple nutrient solutions into the injection tank 5 through the injection tube 11, and then start the motor 9 through the operation button set on the front of the enteral nutrition pump body 1. The motor 9 drives the stirring rod 10 to rotate, and the stirring rod 10 mixes the multiple nutrient solutions to avoid agglomeration or accumulation. The mixed nutrient solution can be directly discharged through the outlet tube 12, and can also be discharged into the infusion tube 2 through the second shunt tube 13.

[0020] When the nutrient solution inside the infusion tube 2 needs to be diluted, the pulse pump 6 is started through the operation button set on the front of the enteral nutrition pump body 1. The pulse pump 6 draws the warm water inside the water tank 3 into the infusion tube 2 through the pulse tube 7, so that the warm water and the nutrient solution inside the infusion tube 2 are input into the patient's gastrointestinal tract together, thereby completing the dilution work.

[0021] The present invention has the following beneficial effects:

[0022] Through the setting of the water supply component, the present invention can pump warm water into the infusion tube through the pulse pump, so that it can be input into the patient's gastrointestinal tract together with the nutrient solution in the infusion tube to achieve the purpose of dilution, which can reduce the blockage of the pipeline or the discomfort of the patient. Through the setting of the processing component, the various nutrient solution raw materials added can be automatically mixed, reducing the workload of medical staff. In addition, through the cooperation of the water tank, the pulse pump and the pulse tube, the pipeline after use can be effectively pulse-flushed, which greatly saves work efficiency.

[0023] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
