Examples

As shown in fig. 1-2, the present application provides a novel food injector, which comprises a barrel 100, wherein a food injection port 110 is arranged at one end of the barrel 100, a backflow prevention structure 700 is detachably arranged at the food injection port 110, and a food outlet 710 is arranged at one end of the backflow prevention structure 700. The cylinder 100 is made of food-grade stainless steel, and the feeding port 110 may be integrally designed with the cylinder 100. The backflow preventing structure 700 is detachably arranged with the feeding port 110, so that cleaning is facilitated.

A piston 200 is arranged in the cylinder 100, and the piston 200 is matched with the inner wall of the cylinder 100; a driving device 400 is arranged on the cylinder 100 far away from the feeding port 110, and the driving device 400 drives the piston 200 to move in the cylinder 100;

the piston 200 is provided with a first heating layer 500, and the end of the cylinder 100 near the feeding port 110 is provided with a second heating layer 600. The first heating layer 500 and the second heating layer 600 are both connected to a power source, and generate heat by being energized. In practical applications, a battery 420 may be provided on the aid, with both heating layers being powered by the battery 420.

The novel food injector comprises a barrel body 100, wherein a food injection port 110 is formed in one end of the barrel body 100, a backflow preventing structure 700 is detachably arranged at the food injection port 110, and a food outlet 710 is formed in one end of the backflow preventing structure 700. The piston 200 is arranged in the barrel 100, the driving device 400 is arranged on the barrel 100 far away from the feeding port 110, and food can be sucked from the feeding port 110 or poured into the barrel 100 from one end of the barrel 100 during feeding. In the feeding process, the driving device 400 automatically drives the piston 200 to move, and the piston 200 pushes food to be fed. The piston 200 is provided with a first heating layer 500, and one end of the cylinder 100 near the feeding port 110 is provided with a second heating layer 600. The two heating layers can heat food simultaneously when in use, so as to ensure the temperature of the food. And after one injection, when the piston 200 is reset, saliva is not sucked from the mouth of the patient due to the backflow preventing structure 700, which not only ensures the cleanliness of food in the cylinder 100, but also prevents the temperature of the food from being lowered due to saliva. In general, the feeder is convenient to use, can avoid the influence of too low food temperature on intestines and stomach of a patient, and is beneficial to improving the use experience of the patient. The backflow preventing structure 700 includes a backflow preventing section 720 and a connecting section 730, which are mutually communicated, and the backflow preventing section 720 is in threaded connection with the feeding port 110.

Specifically, the using method of the feeder comprises the following steps: food is sucked through the feeding port 110 or is poured through one end of the cartridge 100. During feeding, the piston 200 is driven by the driving device 400 to move along the length direction of the cylinder 100. The piston 200 presses the food in the cartridge 100 so that the food flows out of the feeding port 110, passes through the backflow preventing structure 700, and enters the mouth of the patient. The moving speed of the piston 200 can be set by the driving device 400, so as to realize the quantitative feeding. When the food is required to be sucked again after one-time feeding is completed, the piston 200 is driven by the driving device 400 to move reversely, so that the food is sucked. It should be noted that, during the feeding process, that is, when the feeding port 710 of the feeding apparatus is located in the mouth of the patient, the backflow preventing structure 700 needs to be installed to prevent the feeding apparatus from sucking the mouth water of the patient. When sucking food, the backflow preventing structure 700 may be detached first to enhance the food sucking efficiency.

Further, the backflow preventing structure 700 includes a backflow preventing section 720 and a connecting section 730, which are connected to each other, and the backflow preventing section 720 is screwed with the feeding port 110. The connecting end which is connected through the screw thread is convenient to assemble and disassemble, and is convenient for later cleaning and maintenance.

Further, the backflow prevention section 720 is provided with a first backflow prevention cavity 7201 and a second backflow prevention cavity 7203 which are sequentially connected, the first backflow prevention cavity 7201 is connected with the connection section 730, and one end of the second backflow prevention cavity 7203 is provided with the food outlet 710; the diameters of the first backflow preventing cavity 7201 and the second backflow preventing cavity 7203 gradually decrease along the direction from the connection section 730 to the food outlet 710. Further, the axes of the first backflow preventing cavity 7201 and the second backflow preventing cavity 7203 are not coincident, and the first backflow preventing cavity 7201 is communicated with the second backflow preventing cavity 7203 through a transition cavity 7202.

The two backflow preventing sections 720 may enhance the backflow preventing effect of the backflow preventing structure 700. The diameters of the first and second backflow preventing cavities 7201 and 7203 gradually decrease in the direction from the connection section 730 to the food outlet 710. The flow area of the backflow preventing cavity near the connection section 730 is larger than the flow area of the backflow preventing cavity far away from the connection section 730, so that when the piston 200 moves to the side far away from the feeding port 110, a larger suction force is required to enable the liquid (saliva) to enter the cylinder 100 through the backflow preventing structure 700. And the movement path of saliva is prolonged due to the connection section 730, and the backflow preventing effect of the backflow preventing structure 700 is improved.

In a specific embodiment, the first heating layer 500 includes a heating plate 520 and a heat conductive plate 510, the heating plate 520 is disposed on the piston 200, the heat conductive plate 510 is disposed at one side of the heating plate 520, and the heat conductive plate 510 is exposed in the cylinder 100.

It should be noted that, the driving motor 410 is a motor that can be rotated in opposite directions, so that the piston 200 is controlled to move in two different directions by the driving motor 410. The controller 430 should include control buttons, such as a button for controlling the forward movement of the piston 200 (moving in the direction of the feeding port 110) and a button for controlling the backward movement of the piston 200.

Further, a temperature detector 900 is disposed on the end of the barrel 100 near the feeding port 110, and the temperature detector 900 is electrically connected to the controller 430. The temperature detector 900 may be configured to detect the temperature of the food in the drum, or may be configured to detect the wall temperature of the drum 100, and estimate the temperature of the food in the drum 100 from the wall temperature of the drum 100. In practical applications, the temperature of the food is preferably controlled to be 30-40 ℃, and when the temperature of the food exceeds 40 ℃, the controller 430 alarms to remind the feeding personnel of paying attention.
