Self-help stomach tube food injector with controllable speed and temperature

Abstract

The invention discloses a self-help stomach tube food injector with controllable speed and temperature, which comprises a fixed shell, an injector, a driving device, a controller, a stomach tube and a temperature controller, wherein the fixed shell is provided with an injector fixing groove; the injector is placed in the injector fixing groove and comprises a sleeve and a push rod, the sleeve is detachably fixed in the injector fixing groove, an injection head at the front end of the sleeve is stretched out of the fixed shell, and the push rod is sheathed in the sleeve in a horizontally moving manner; the driving device is fixed at the tail of the fixed shell and comprises a micro motor, a shaft sleeve, a screw and a screw sleeve, the output shaft of the micro motor is connected with the tail of the screw through the shaft sleeve, and the screw sleeve is sheathed at the front end of the screw and is in contact with the push rod in the injector; the controller is installed on the driving device; and the stomach tube and the temperature controller are sheathed in the front end of the sleeve. The self-help stomach tube food injector with controllable speed and temperature can realize automatic and uniform feeding and automatic control over feeding time through the controller, and does not need manual operation in the whole course, thus alleviating the feeding labor intensity for a nurse or a family member of a patient.

Description

technical field [0001] The invention relates to a feeding device, in particular to a self-service gastric tube feeding device with controllable speed and temperature. Background technique [0002] Some paralyzed patients who are bedridden all year round cannot eat independently due to the loss of chewing and swallowing functions. They usually need to insert a gastric tube, and then inject liquid food into the gastric tube with a disposable syringe, which requires nurses or family members to use their fingers to push hard The plunger handle of the syringe injects liquid food into the patient's stomach. Due to the limitation of the viscosity of the food and the diameter of the gastric tube, it is often difficult for nurses or family members to push the syringe, making the feeding process last for a long time, which is time-consuming and laborious for the patient. In addition, due to the difficulty in controlling the strength of fingers when injecting food, the injection speed ...

AI Technical Summary

Problems solved by technology

However, the device still has the following defects: (1) Since the syringe is placed in an open environment, the time for injection and feeding is relatively long, especially in environments with a lot of bacteria such as hospitals, which can easily lead to cross-infection of bacteria; ( 2) The syringe is placed in an open environment without heat preservation, the liquid food in the syringe is easy to cool down, especially when the feeding time is long, it will affect the patient's gastrointestinal absorption and cause adverse effects to the patient; ( 3) The device can only automatically control the feeding speed, but cannot automatically control the feeding time; (4) The tail of the syringe plunger needs to be fixed in the U-shaped buckle on the push-pull plate to work.
