Description

A simple nasal feeding device

technical field

The utility model relates to the technical field of post-care, in particular to a simple nasal feeding device.

Background technique

At present, most medical staff in clinic use 50ml syringes to feed patients who cannot take oral feedings, and also teach family members to use syringes to feed patients in the later stages of family members' participation in the nursing process. Through a large number of clinical observations, it is found that there are many deficiencies in injecting food with a syringe, as follows:

Due to the small diameter of the syringe, the process of sucking food is laborious, and food with a slightly thicker consistency cannot be sucked in at all.

The syringe with the largest capacity in clinical work is 50ml. When the patient's condition allows, the daily injection of 200ml is required. Only after scoring four times can the injection requirements be met. Repeatedly opening and closing the cap on the top of the nasal feeding is easy to increase bacterial contamination. The process also requires repeated suction, which virtually increases the workload and time-consuming of nurses and their families.

Because the front end of the syringe is short, the contact between the syringe and the nasogastric feeding is easy to seep.

In the process of repeated use of the syringe, the friction between the tube wall and the piston increases, which increases the suction force and makes it difficult to suck. At this time, the syringe must be replaced before feeding. According to the clinical observation results of our department, the evaluation was averaged for two days. A new syringe needs to be replaced, which increases the medical expenses of patients and the increase of medical waste in the society. Some family members do not throw the discarded syringes into the designated places according to the regulations, and discard them at will, which is not conducive to environmental protection.

The syringe barrel is long and difficult to clean.

Problems with the mechanical behavior of linear deformation.

In order to achieve the above purpose, the utility model provides the following technical solutions: a simple nasal feeding device, comprising a feeding support and a hand-pressed handle on the feeding support, characterized in that: a three-way pipe structure is arranged in the feeding support , the through pipe at the bottom is connected with the suction pipe, the through pipe at the top is communicated with the nozzle, the through pipe in the middle forms an intermediate storage chamber, a piston is arranged in the intermediate storage chamber, and the piston rod hinged with the piston extends out of the intermediate storage chamber and It is connected with the hand pressing handle, and the upper end of the hand pressing handle is hingedly connected with the feeding support.

Preferably, the inner end of the intermediate storage cavity is a conical structure, and a preload spring is arranged in the intermediate storage cavity, and the preload spring is located between the conical structure and the piston.

Preferably, a one-way valve is arranged at the straw so that the food can only flow from the straw into the three-way pipe structure, and the three-way pipe structure cannot flow into the straw, and the end of the straw is inserted into the bottle body.

Preferably, the nozzle is connected to the corresponding gastric tube, and a one-way valve is arranged in the three-way tube structure at the nozzle, so that when the gastric tube is a large-diameter gastric tube, a frustoconical shape matching the large-diameter gastric tube is provided. Nozzle, the first 1.5cm is set with a diameter of 0.4cm, and the rear 0.5cm is set to match the large-diameter gastric tube, which is conducive to the injection of viscous food. When using a gastric tube with a small diameter, the inner diameter of the small diameter gastric tube is 0.3 cm, and a cylindrical nozzle matching the small diameter is set, and the length is 1 cm.

Compared with the prior art, the utility model utilizes a three-way pipe structure, and the food in the bottle can be continuously injected into the patient by means of extrusion or negative pressure. It is easy to clean, effectively saves the time of nurses and their families, and it is convenient to heat at any time. Just pour the food into the bottle and cover it, and then put the bottle into a cup of suitable size with hot water to heat it. It effectively solves the problem that patients and their families cannot use electrical appliances to heat food at will in the hospital.
