Description

Blocking structure and air-blocking feeder

This creation is about a blocking structure and a douche, especially a blocking structure that can block air and facilitate cleaning during feeding, and a douche that blocks air.

Referring to the first figure, a liquid food or medicine is poured into a nasogastric tube 20 through a feeding needle 10, and then fed into the human body through the nasogastric tube 20. This is a technique that requires patience and concentration. During the process, air may flow into the human body through the feeding needle tube 10 to the nasogastric tube 20, causing discomfort for the patient’s flatulence. Part of the nasogastric tube 20 of the needle tube 10 is folded back so that air will not flow to the nasogastric tube 20 through the feeding needle tube 10 during the feeding process, but if the nasogastric tube 20 is not fully folded back, the air will still pass through the feeding process The needle tube 10 flows to the nasogastric tube 20. Furthermore, the feeder needs to operate the nasogastric tube 20 all the time or for a long time to reverse the movement of the nasogastric tube 20, which may easily cause fatigue and soreness of the hands.

Based on the above technical features, the main effects of the blocking structure and the air blocking douche of the present invention will be clearly presented in the following embodiments.

Referring to the second to fourth figures, an embodiment of the air-blocking applicator according to the present invention. The air-blocking applicator includes a feeding needle tube 1 and a blocking structure 2.

The feeding needle tube 1 includes a surrounding wall 11, a shoulder wall 12, and an output end wall 13. The surrounding wall 11 has a cylindrical shape, the shoulder wall 12 is connected between the surrounding wall 11 and the output end wall, and is inclined, and the output end wall 13 extends away from the surrounding wall 11 and also has a The cylindrical shape, the surrounding wall 11 and the shoulder wall 12 define an accommodating space 14, the output end wall 13 defines a feeding channel 15, and the feeding channel 15 is communicated with the accommodating space 14.

The blocking structure 2 includes a blocking element 21, a temperature sensing element 22, and a wire body 23.

The blocking member 21 is movably disposed in the accommodating space 14 and includes a first blocking portion 211 and a second blocking portion 212. The first blocking portion 211 includes a first end surface 213, a second end surface 214 and a connecting surface 215. The first end surface 213 is opposite to the second end surface 214, and the area size of the first end surface 213 is larger than the area size of the second end surface 214. The first end surface 213 is recessed to form a concave hole 216, and the connecting surface 215 is connected It is between the first end surface 213 and the second end surface 214 and tapers from the first end surface 213 to the second end surface 214. The first blocking portion 211 is made of silicon rubber. The second stopping portion 212 is generally in a sheet shape and the color is transparent. The second stopping portion 212 is disposed on the first stopping portion 211, and the second stopping portion 212 movably closes the concave hole 216 . The second blocking portion 212 is made of silicon rubber.

The temperature sensing element 22 is movably disposed on the stopper 21. In this example, the temperature sensing element 22 is disposed in the recessed hole 216. When the temperature sensed by the temperature sensing element 22 does not exceed a critical temperature, a first color is displayed, and when the sensed temperature of the temperature sensing element 22 exceeds the critical temperature, the temperature sensing element 22 changes to display a second color, When the sensing temperature of the temperature sensing element 22 returns to less than the critical temperature, the temperature sensing element 22 returns to display the first color. In this example, the temperature sensor 22 is a replaceable temperature sensor paper.

The wire body 23 is partially accommodated in the accommodating space 14 and includes a first end 231, a second end 232, and a set of ring 233. The first end 231 is opposite to the second end 232, and the first end 231 is opposite to the second end 232. The end 231 is connected to the center of the stopper 21, the second end 232 is outside the accommodating space 14, and the collar portion 233 is connected to the second end 232. In this example, the wire body 23 penetrates through the center of the first stop portion 211, the second stop portion 212, and the temperature sensor 22, and the first end 231 is fixed to the first stop portion The center of 211.

Referring to the fourth to sixth figures, when in use, the accommodating space 14 of the feeding needle tube 1 contains a feeding liquid 30, and the second stopper 212 floats on the surface of the feeding liquid 30 to isolate air from The filling liquid 30 is more transparent due to the color of the second stopping portion 212, which facilitates observing the color displayed by the temperature sensor 22. If the temperature sensor 22 displays the first color, it indicates that the filling The food liquid 30 is a temperature suitable for filling. If the temperature sensor 22 displays the second color, it means that the filling liquid 30 is a temperature not suitable for filling. Therefore, the temperature sensor 22 is used to take care of The person judges whether the feeding liquid 30 is at a temperature suitable for feeding. During the feeding process, the feeding liquid 30 flows to a nasogastric tube 40 through the feeding channel 15. The feeding liquid 30 gradually drops in the feeding needle tube 1, and the stopper 21 follows the feeding liquid The descent of 30 follows the movement to keep isolating the air and the feeding liquid 30 continuously. Because the thread body 23 penetrates the center of the first stop portion 211, the second stop portion 212, and the temperature sensor 22, The first stop portion 211, the second stop portion 212, and the temperature sensor 22 are not easily skewed during the movement process, and can maintain good isolation.

When the feeding liquid 30 completely flows to the nasogastric tube 40, the connecting surface 215 abuts the shoulder wall 12, the second end surface 214 blocks the feeding channel 15, and the stopper 21 blocks the feeding channel 15 , So that the accommodating space 14 and the feeding channel 15 are not connected, so that air will not flow to the nasogastric tube 40 anymore. What’s more convenient is that the caregiver can easily pull the stopper 21 and the stopper 21 by the wire body 23 by pulling the loop part 233. The temperature sensing element 22 is pulled out, so that the feeding needle tube 1 and the blocking structure 2 are easy to clean, and the temperature sensing element 22 is easy to replace.

In summary, when the stopper 21 abuts against the shoulder wall 12, the stopper 21 blocks the feeding channel 15 so that the accommodating space 14 is disconnected from the feeding channel 15 to avoid feeding The process allows air to flow from the feeding needle tube 1 to the nasogastric tube 40 to the human body, causing discomfort for the patient’s flatulence. The thread body 23 facilitates the pulling out of the stopper 21, making it easier to clean the stopper. The stopper 21 and the feeding needle tube 1 use the temperature sensor 22 to sense the temperature to allow the caregiver to determine whether the feeding liquid 30 is at a temperature suitable for feeding, so as to avoid scalding the patient during the feeding process.
