Embodiment 1

[0038] Embodiment one is basically as attached figure 1 Shown: postoperative enteral nutrition administration device, including cooling chamber 5, disinfection chamber, secondary cooling chamber 5 and heat preservation chamber 16 arranged inside the administration device 1 from top to bottom, cooling chamber 5 It is connected with a catheter 23 for feeding enteral nutrition into the cooling chamber 5 (the catheter 23 can be connected with a pump, and the power of the pump is used to deliver the enteral nutrition into the cooling chamber 5). The outer wall of the chamber 5 is provided with a first cooling channel 4 , the first cooling channel 4 communicates with the cooling liquid supply chamber 2 , and a first pressure valve 3 is provided between the first cooling channel 4 and the cooling liquid supply chamber 2 .

[0039] The bottom of the cooling chamber 5 communicates with the disinfection chamber, and the connection between the cooling chamber 5 and the disinfection chamb...

Embodiment 2

[0049] Such as image 3 As shown, the difference between the second embodiment and the first embodiment is that the second cooling chamber 15 is columnar, and the outer wall of the cooling stirring rod 14 is attached and slidably connected to the inner wall of the second cooling chamber 15 .

[0050] When the cooling stirring rod 14 is in the process of rotating around the central axis of the second cooling chamber 15, the outer wall of the rotating stirring rod can scrape off the comparatively viscous enteral nutrient solution remaining on the second cooling chamber 15 inner wall, And it can be thrown out under the action of the centrifugal force of its rotation, so that the residual enteral nutrition solution can also be transported away, ensuring the capacity of the enteral nutrition solution delivered to the patient, avoiding waste, and also convenient for the second cooling Cleaning of the inner walls of the chamber 15.

Embodiment 3

[0052] Such as Figure 4 As shown, the difference between the third embodiment and the second embodiment is that the cooling stirring bar 14 includes a cleaning strip 28, the section of which is triangular in shape, the tip of which is slidingly connected with the inner wall of the second cooling chamber 15, and the other end of which is Fixedly connected with the cooling stirring rod 14, the cleaning strip 28 is arranged on its outer wall along the axis of the cooling stirring rod 14, and the outer wall of the cooling stirring rod 14 is slidably connected with the inner wall of the second cooling chamber 15 by the cleaning strip 28, and the cleaning strip 28 Made of food grade silicone material.

[0053] The outer wall of the cooling stirring rod 14 is provided with a cleaning strip 28 with a triangular cross-section, which can increase its cleaning ability when the cooling stirring rod 14 rotates, so that the enteral nutrition solution on the inner wall of the second cooling...

Abstract

The invention relates to the technical field of medical instruments, in particular to a postoperative enteral nutrition dosing device. The postoperative enteral nutrition dosing device comprises a cooling chamber, a disinfection chamber, a secondary cooling chamber and a heat preservation chamber which are arranged in the dosing device from top to bottom, wherein the cooling chamber communicates with a catheter used for conveying an enteral nutrient solution into the cooling chamber, and a first cooling channel is arranged on the outer wall of the cooling cavity and communicates with a cooling liquid supply chamber; and the bottom of the cooling chamber communicates with the disinfection chamber, a pressure valve is arranged at the communication position between the cooling chamber and the disinfection chamber, a disinfector is arranged in the disinfection chamber, the bottom of the disinfection chamber communicates with a second cooling chamber, the bottom of the second cooling chamber communicates with the heat preservation chamber, and the heat preservation chamber communicates with the catheter used for conveying the enteral nutrient solution into the intestines of a patient. Therefore, the problem that the risk that the enteral nutrient solution in the dosing device is polluted and deteriorated is increased due to the fact that the dosing device usually needs to be opened for multiple times is solved, and the dosing device is mainly used for medical institutions.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a postoperative enteral nutrition administration device. Background technique [0002] There are many diseases in clinical medicine that can cause patients to be unable to eat normally by mouth. For such patients, nutritional support needs to be given in a special way when taking food and nutrition, which includes parenteral nutrition and enteral nutrition supply in clinical practice. [0003] The enteral nutrition supply route is currently the most widely used option with the best safety and effectiveness. It is mainly a nutritional support method that provides nutrients for metabolism and other nutrients through the gastrointestinal tract. For patients with gastrointestinal lesions before surgery, such as gastric cancer, esophageal cancer, etc., who cannot eat orally, such as radical gastrectomy, esophageal cancer, etc., usually use nasogastric nutrition tube, nasointe...
