Description

Technical Field

[0001] The utility model belongs to the technical field of clinical equipment, in particular to an enteral nutrition supply device for tumor patients. Background Art

[0002] During the treatment of tumor patients, a nutrition supply device is needed to deliver nutrition to the patients. Gastrointestinal malignant tumors include gastric cancer and colorectal cancer. Most of these patients are accompanied by varying degrees of malnutrition. Malnutrition in patients with gastrointestinal malignant tumors will directly affect the anti-tumor treatment effect, the quality of life and survival time of the patients. Clinically, patients with gastrointestinal tumors cannot swallow food orally and can only receive nutrition through an enteral nutrition tube. The enteral nutrition input tube is connected to the patient's stomach, duodenum and upper jejunum through the nasal cavity. The nutrient solution enters the gastrointestinal tract through the pipeline to achieve the nutrition supply for the patient. When the existing nutrition supply device is used, it usually injects nutrition into the patient in a hanging manner. For a nutrient storage bottle or nutrient storage bag without a hanging ring, it is not convenient to hang, reducing the usability of the nutrition supply device.

[0003] For example (the authorized announcement number is CN213698301U), a clinical enteral nutrition supply device includes a vehicle body, a battery slot, a hinge, a base, a telescopic rod, a threaded hole and a bolt. A fixed buckle is fixedly connected to one side of the telescopic rod, a top plate is fixedly connected to the upper surface of the telescopic rod, a warning light is arranged on the upper surface of the top plate, a hook is fixedly connected to one side of the top plate, a water storage tank is arranged inside the vehicle body, a water inlet pipe is inserted into one side of the water storage tank, and a water pump is arranged on one side of the water storage tank. The main advantage of the utility model is to provide a clinical enteral nutrition supply device. The user can first push the vehicle body to the patient's hospital bed, adjust the telescopic rod to an appropriate height, then hang the nutrition supply bag on the hook, place the infusion tube in the fixed buckle to fix it, and finally insert the infusion head into the patient's abdomen to supply enteral nutrition, improving the stability during nutrition supply. However, this device does not consider hanging a nutrient storage bottle or nutrient storage bag without a hanging ring, reducing the usability of the nutrition supply device.

The moving ring moves downward along the path of the limiting rod, and it is convenient to adjust the longitudinal position of the support for the nutrition storage bottle or the nutrition storage bag during the transmission process.

[0014] The enteral nutrition supply device for tumor patients facilitates the rotation of the threaded sleeve, so that the threaded sleeve moves longitudinally along the threaded path of the lead screw. During the transmission process, it is convenient for the lead screw to extend into the inner cavity of the support rod, so as to adjust the suspension and support fixing height of the nutrition storage bottle or nutrition storage bag for the treatment of tumor patients. The set limit bearing provides a fixing effect on the rotation position of the threaded sleeve, and at the same time realizes the relative rotation of the threaded sleeve and the support rod, improving the structural stability of the device components. The square inner cavity opened on the top surface of the support rod is slidably connected with the square limit plate, preventing the lead screw from rotating when moving along the threaded path of the threaded sleeve during the transmission process, further improving the structural stability of the device components. The bottom surface of the set support plate contacts the ground to provide a support function. Description of the Drawings
