Description

Nasal feeding delivery device

technical field

The utility model relates to a feeding and conveying device for nasal feeding.

Background technique

Nasogastric feeding is to manually insert the gastric tube into the esophagus through the nasal cavity under special circumstances. First, the food is mashed with a grinder, and a large syringe is used to connect the large feeding port under the gastric tube joint. After the connection is firm, manually pressurize the push rod. The piston draws water and food into the patient's stomach to help patients who cannot swallow on their own to provide water and food to maintain metabolism, body weight and nutrition in the body. During nasal feeding, it is necessary to switch between food and warm water at intervals to facilitate feeding. However, in the prior art, a single large syringe is used for feeding, which requires connection and switching between two syringes, and has problems such as cumbersome operation.

The interface to which the gastric tube is connected.

Wherein, the cylinder body includes a front section and a rear section that is threadedly connected to the front section, and the outlet is arranged in the rear section; an end of the front section close to the rear section is provided with an internal thread, and the rear section is close to the front section. One end is provided with an external thread, and after the internal thread is connected with the external thread, the inner wall of the external thread on the rear section is connected and flush with the inner wall of the end of the internal thread on the front section.

Wherein, a peripheral edge is provided on the periphery of the rear section, and the lower end of the peripheral edge extends out of the outlet.

Wherein, the rear section has a pipeline extending in a direction away from the front section, the outlet is located in the pipeline, and an external thread is provided outside the pipeline.

Wherein, it also includes a cap which can be connected with the external thread on the pipeline.

Compared with the prior art, the beneficial effects of the present utility model are: the nasal feeding feeding and conveying device in the present utility model is a conveyor for pushing water liquid when it needs to transport water liquid, and a conveyor for pushing food when it needs to transport food, The overall operation is simple and convenient, no need to connect back and forth.

Figure 1 is a schematic structural diagram of the present invention.

Detailed ways

The present utility model will be further described below with reference to the accompanying drawings and through embodiments.

As shown in FIG. 1 , the nasal feeding and conveying device of this embodiment includes a conveyor, and the conveyor includes a cylinder 1; the cylinder 1 has a cavity, and one end and two ends of the cylinder 1 pass through; The piston 2 in 1 and sealed with the cylinder body 1 and movably arranged, the piston 2 is a rubber piece, the piston 2 is fixedly connected with a push rod 5, and one end of the cylinder body 1 is provided with an outlet 10; the conveyor is two, and the two convey The outlet 10 of the device is screwed together with two one-way valves 3 which are unobstructed from the inside of the cylinder 1 through the outlet 10 to the outside world. In this embodiment, the gastric tube is a catheter inserted into the stomach of the human body through the nasal cavity. When in use, two conveyors are used to connect two one-way valves 3 respectively. 10 into the cylinder 1 is closed. In the process of nasal feeding, the two conveyors are filled with liquid food and water respectively, and the push rod 5 can be pushed to drive the piston to move according to the needs, so as to transport food and water at intervals, without manual switching, compared with the existing technology that requires switching operation. The program is more convenient.

Preferably, in order to further facilitate filling of food or water, the cylinder body 1 includes a front section 11 and a rear section 12 threadedly connected to the front section 11, and the outlet 10 is provided at the rear section 12; The end of the rear section 11 close to the rear section 12 is provided with an internal thread 111, and the end of the rear section 12 close to the front section 11 is provided with an external thread 121. After the internal thread 111 is connected with the external thread 121, the rear section 12 The inner wall of the upper outer thread 121 is connected to and flush with the inner wall of the end of the inner thread 111 of the front section 11 . In this embodiment, the cylinder body 1 is divided into two detachable sections, and the two sections can be connected with threads. After the threads are connected, the inner wall is flush, and the piston 2 moves smoothly. When filling food, remove the rear section 12 as a Preferably, it also includes a cap that can be threadedly connected to the external thread 121 on the pipeline. The cap is used to seal the outlet 10, and then through filling the food, the diameter of the filling food is larger and more convenient. threaded connection. After removing the cap, the outlet 10 is connected to the inlet end of the check valve 3 .

In this embodiment, a peripheral edge 6 is provided on the periphery of the rear portion 12 , and the lower end of the peripheral edge 6 extends out of the outlet 10 . When the rear section 12 is placed on the table top, the surrounding edge 6 is attached to the table top, so that the rear section 12 can stand, which is convenient for filling food.

In this embodiment, the rear section 12 has a pipeline extending in a direction away from the front section 11 , the outlet 10 is located in the pipeline, and an external thread is provided on the outside of the pipeline. It also includes a cap 7 that can be connected with the external thread on the pipeline, and uses the cap 7 to block the outlet 10 .
