Description

Technical Field

[0001] The present invention relates to the technical field of feeding devices, in particular to a feeding device for food after oral surgery and an operating method thereof. Background Art

[0002] After oral surgery, some patients are unable to chew food due to surgical trauma, functional limitations or pain, and need to use a feeding device to feed liquid food into the patient's mouth.

[0003] Typically, after a certain amount of liquid food is placed in a feeding container, a silicone feeding tube is placed into the patient's mouth to deliver the liquid food. However, some patients may accidentally bite the feeding tube when they are unconscious or emotionally unstable after surgery. This can cause the silicone material of the feeding tube to deform easily, leading to blockage inside the tube and significantly reducing the speed of delivering liquid food to the patient's mouth. Furthermore, for some patients with strong bite forces, the feeding tube may rupture, causing the liquid food being delivered inside the feeding tube to leak out of the rupture and splash onto the patient's body or clothing, contaminating the clothing and causing inconvenience to medical staff.

The feeding tube 2 is made of ultra-soft silicone or TPE material, which greatly reduces the risk of friction and damage to oral mucosa, sutures, and fragile tissues, and is especially suitable for sensitive areas after surgery. The food storage cylinder 1 is transparent, and the scale lines 9 on both sides facilitate medical staff to observe the capacity of the liquid food in the food storage cylinder 1. The temperature indicator label 10 uses a reversible thermochromic material. When the food temperature exceeds a safety threshold (such as >40°C), it changes color to alert medical staff to the risk of overheating and avoid scalding the patient. After the patient finishes eating, the end of the feeding tube 2 is taken out from the inside of the patient's mouth, then the rotating ring 25 is moved to one side of the moving ring 24 by pressing, and the bearing ring plate 32 is moved synchronously with the two guide rods 33, the two reset springs 34 are compressed, until the multiple grooves 30 at one end of the rotating ring 25 cooperate with the clamping blocks 31, the position of the rotating ring 25 is adjusted, the multiple clamping blocks 31 are clamped into the inside of the multiple grooves 30, thereby connecting between the rotating ring 25 and the moving ring 24, in this state, rotating the rotating ring 25, the moving ring 24 is rotated, and the multiple driving rods 26 are moved synchronously under the action of the moving ring 24, the multiple driving rods 26 slide along the respective strip-shaped grooves 27, and the respective sliding blocks 28 slide in the corresponding annular sliding grooves 29, with the movement of the multiple driving rods 26, the end of the multiple driving rods 26 away from the moving ring 24 acts on the sealing plug 21, the sealing plug 21 is forced to move away from the through hole two 20, the through hole two 20 is opened, and the outside air enters the inside of the negative pressure cavity 16 through the through hole one 19 and the through hole two 20, the pressure in the inside of the negative pressure cavity 16 is the same as the outside, and the multiple negative pressure heads 17 no longer adsorb the feeding tube 2, so that the entire fixing ring 11 can be taken off, the fixing ring 11 and the annular bite-preventing plate 12 can be cleaned for the next use of the patient, the annular bite-preventing plate 12 can be used multiple times, which is beneficial to saving cost, and when the rotating ring 25 is rotated by mistake of the patient or the medical staff during use of the annular bite-preventing plate 12, the rotating ring 25 only idles by itself and does not rotate the moving ring 24, so that the patient or the medical staff is effectively prevented from causing the negative pressure mechanism to be relieved of pressure and causing the fixing ring 11 and the feeding tube 2 to slide when the rotating ring 25 is touched by mistake.

[0028] The application further discloses an operation method of the oral cavity postoperative food feeder.
