Description

Nasogastric tube feeding device

technical field

The utility model relates to the field of medical auxiliary equipment, in particular to a nasogastric tube feeding device.

Background technique

Oral cancer patients after extensive resection surgery, oral structure changes may lead to difficulty in opening the mouth, incomplete closure of the lips or difficulty in swallowing. If patients cannot overcome oral feeding, they need to rely on nasogastric tube for long-term force-feeding. It not only affects social activities, but also increases the potential danger of pipeline placement and the cost of home care.

Nasogastric tube feeding has been widely used clinically, and can be slowly instilled through a nasal feeding pump or a nasogastric tube. Nasal feeding pump can be selected in the hospital, but for patients who are fed by gastrointestinal tube at home, it is specially purchased, and the cost is too high; while enteral nutrition pump tube dripping is acceptable for finished nutritional preparations in bottles or bags, but for self-made nutritional preparations. Liquid food or nutritional preparations that need to be dissolved in powder, due to uneven mixing or large particles, are likely to block the enteral nutrition pump tube, and need to use a syringe to inject into the gastrointestinal tube.

Utility model content

In view of this, the utility model proposes a nasogastric tube feeding device to solve the problems of eating and swallowing difficulties of oral cancer patients.

On the one hand, the utility model provides a nasogastric tube feeding device, which includes a feeding bottle, a conical joint, and a nasogastric tube; the feeding bottle is made of plastic or rubber, and a liquid inlet channel is opened in the conical joint. The big end of the connector is connected to the feeding bottle, the small end of the tapered connector is inserted into the inlet connector of the nasogastric tube, a liquid outlet hole is opened on the end side wall of the nasogastric tube, and the size scale is printed on the outer wall of the nasogastric tube .

Detailed ways

It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The utility model will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

Below in conjunction with Fig. 1 to Fig. 2, the preferred embodiment of the present utility model is described in further detail, a kind of nasogastric tube feeding device of this preferred embodiment: comprises feeding bottle 1, tapered joint 2, nasogastric tube 3; Feeding bottle 1 is made of plastic or rubber, and a liquid inlet channel 21 is opened in the conical joint 2. The large end 20 of the conical joint 2 is connected to the feeding bottle 1, and the small end of the conical joint 2 is inserted into the inlet joint of the nasogastric tube 3 , On the end side wall of the nasogastric tube 3, a liquid outlet hole (not shown in the figure) is opened, and a size scale (not shown in the figure) is printed on the outer wall of the nasogastric tube 3 .

When eating, fill the feeding bottle 1 with liquid diet, tilt the feeding bottle 1, put the nasogastric tube 3 along the edge of the tongue and place it at the back third of the tongue, gently squeeze the feeding bottle 1 and cooperate with sucking or swallowing actions to complete eat.

When gargling, the feeding bottle 1 contains mouthwash, the nasogastric tube 3 is inserted into the oral cavity, the feeding bottle 1 is squeezed, and the nasogastric tube 3 is operated to move in the oral cavity, so that the mouthwash can thoroughly rinse every corner of the oral cavity.

The nasogastric tube 3 can also be inserted into the esophagus or the stomach through the oral cavity, or inserted into the esophagus or the stomach through the nostril, and then gently squeeze the feeding bottle 1 to realize eating.

As shown in FIG. 1 , in order to prevent the conical connector 2 from breaking away from the nasogastric tube 3 during feeding, causing nutrition to flow out. The opening of the feeding bottle 1 is provided with an external thread; the large end 20 of the conical joint 2 is provided with an internal thread, and the external thread is connected with the internal thread, and the small end 23 of the conical joint 2 is a conical structure. At least two inverted tapered rings 22 are arranged on the outer surface of the small end 23 of the joint 2 , and the small end 23 of the conical joint 2 is inserted into the inlet joint of the nasogastric tube 3 . The cross-sectional area of the inner cavity of the inlet joint of the nasogastric tube 3 gradually decreases from the outside to the inside. Thereby, the sealing between the tapered joint 2 and the nasogastric tube 3 is realized to prevent detachment.

In addition, at least two sealing ring grooves may be provided on the outer surface of the small end 23 of the conical joint 2, and a sealing ring may be provided on the sealing ring grooves.

In order to prevent the increase of feeding resistance during feeding, air will enter the stomach and cause stomach bloating. And after feeding, the nutrition in the intestines and stomach flows back into the feeding bottle. A first air hole (not shown in the figure) is opened on the conical joint 2, and an air pipe (not shown in the figure) is connected to the first air hole.

When eating, because there will be air in the nasogastric tube 3, when the feeding bottle 1 is squeezed, the air in the nasogastric tube 3 and the feeding bottle 1 will enter the stomach, causing bloating. At the same time, the resistance to feeding increases. Adding the ventilation tube can make the air in the nasogastric tube 3 and the feeding bottle 1 flow out from the ventilation tube when eating, which will not cause stomach distension and increase the feeding resistance. At the same time, it will not cause the nutrition in the stomach to flow back into the feeding bottle after feeding.

As shown in Figure 2, in order to smoothly insert the nasogastric tube into the esophagus, stomach or oral cavity and prevent insertion into the trachea, the utility model also includes a nasogastric tube guide wire 4. The guide wire handle 41 is consolidated at the head end of the guide wire 4, and a sealing device 40 is arranged between the inlet joint of the nasogastric tube 3 and the guide wire handle 41. The sealing device 40 is provided with a second vent hole 43, and the second vent hole 43 Ventilation alarm device 42 is installed in the position.

When inserting the nasogastric tube 3, the first choice is to insert the nasogastric tube guide wire 4 into the nasogastric tube 3, and then insert the nasogastric tube 3 into the esophagus, stomach or oral cavity. If the nostril is inserted into the esophagus or stomach, it is mistakenly inserted into the trachea, at this moment, there will be air flow in the second vent hole 43, and the ventilation alarm device 42 will detect the air flow signal in the second vent hole 43, thereby sending out an alarm signal , to remind the operator to insert the trachea by mistake, ensuring the safety of use. The sealing device 40 of the present utility model is a conical structure made of rubber, which has good sealing performance and low cost.

The above is only a preferred embodiment of the utility model, and is not intended to limit the utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the utility model should be included in the Within the protection scope of the present utility model.
