Description

Technical Field

[0001] The utility model relates to a nasogastric feeding device, in particular to a nasogastric feeding device which is easy to operate and reuse, and belongs to the technical field of medical instruments. Background Art

[0002] Nasogastric feeding is a common method of maintaining nutritional therapy for patients who cannot eat orally or cannot swallow independently. It involves artificially inserting a gastric tube into the stomach through the patient's nasal cavity, then using a nasogastric insulator to connect the gastric tube and manually pressurize the patient's stomach to inject water, medicine and food.

[0003] The commonly used nasogastric infusion device is a syringe-type infusion device. When in use, it is necessary to manually pull out the piston rod to suck the nasogastric feeding liquid into the syringe, and then push the piston rod to pressurize the nasogastric feeding liquid and inject it into the stomach tube until the patient's stomach. Nasogastric feeding liquid is generally a paste-like substance made by mixing and grinding various foods such as rice and vegetables with water, which will adhere to the syringe and piston, resulting in very laborious suction and injection of nasogastric feeding liquid during nasogastric feeding operation. The syringe capacity of the currently used nasogastric infusion device is 50 ml. Usually, the amount of nasogastric feeding liquid that a patient needs to inject at a time is more than 200 ml, that is, more than 4 barrels need to be repeated. However, when the original nasogastric infusion device is reused from the second barrel for operation, the air in the syringe is completely squeezed out after the piston is pushed to the bottom, and the syringe and piston are stuck together by the attached nasogastric feeding liquid. When suctioning again, the piston is difficult to be pulled apart, and the injection will become more difficult, and it may even be impossible to continue to use, and a new infusion device can only be replaced. Patients who have long-term nasogastric feeding need to bring a gastric tube home from the hospital and have their family members help them with nasogastric feeding. It is more difficult for non-professionals to operate and more perfusion devices are needed. Patients who have long-term nasogastric feeding need to eat multiple meals a day, so a large number of perfusion devices are needed for long-term nasogastric feeding. Therefore, the nasogastric feeding perfusion devices currently used have many problems such as inconvenient operation, laborious use, not conducive to reuse, excessive material consumption, and high economic costs.

[0004] In addition, nasogastric feeding requires the patient to insert a gastric tube and leave it in place. The insertion length of the gastric tube is the distance from the human nostril to the stomach. Generally, 45-55 cm can be inserted through the nose for adults. The length of conventional gastric tubes currently used is 100-120 cm. When the gastric tube is inserted into the stomach, there is still about 50 cm of the gastric tube remaining outside the body. The remaining length is too long and difficult to properly fix. It is easily pulled outward by external force and its own gravity, increasing the risk of gastric tube dislocation. In addition, due to the narrow diameter of the tube, an excessively long gastric tube will increase the resistance of nasogastric feeding, making nasogastric feeding infusion inconvenient and laborious. Utility Model Content

[0005] The utility model aims to provide a nasogastric feeding device which is easy to operate and reuse, and adopts a bottle-type syringe and is equipped with an improved stomach tube with a shortened length and a stomach tube fixer, so as to solve the above-mentioned problems existing in the existing syringe-type syringe and stomach tube in nasogastric feeding operation.

[0006] The technical solution adopted by the utility model is as follows:

[0007] The invention discloses a nasogastric feeding device which is easy to operate and reuse, and comprises a feeding bottle type infuser, an improved stomach tube and a stomach tube fixer.

[0008] The milk bottle type infuser is provided with an infusion head and an infusion bottle; the infusion head is made of food-grade hard plastic material, the lower part of the infusion head is an internally threaded bottle cap matching the bottle mouth of the infusion bottle, the top surface of the bottle cap is provided with a frustum-shaped infusion nozzle which protrudes upward and is connected to the inner side of the bottle cap, the inner side of the bottle cap is provided with a screw hole seat at a position corresponding to the opening of the infusion nozzle, a mesh filter is installed on the screw hole seat, the top surface of the bottle cap is also provided with a vent seat which runs through the inner and outer sides of the bottle cap beside the infusion nozzle, the outer port of the vent seat extending to the outer side of the bottle cap is provided with an openable plug cover, and the inner port of the vent seat extending to the inner side of the bottle cap is provided with an inlet valve for controlling one-way air intake inwardly; the infusion bottle is made of food-grade soft plastic material, the infusion bottle is provided with a bottle mouth and a bottle body, the infusion bottle is screwed on the bottle cap of the infusion head through the screw teeth on the outer circumference of the bottle mouth, the bottle body is a transparent thin wall which can be squeezed and elastically deformed, and the outer side of the bottle body is provided with scale lines and capacity marks corresponding to the scale lines.

[0009] The tube body of the improved gastric tube is 80 cm long, and the rear end of the tube body is connected with an inverted cone tube joint matching the irrigation nozzle.

[0010] The gastric tube fixer is provided with an elastic band, and Velcro sheets that can be bonded to each other are respectively provided at the two ends of the elastic band, and a plastic buckle that can slide and shift along the band body is hung in the middle of the band body of the elastic band; a U-shaped clip groove that matches the tube body of the improved gastric tube is provided in the middle of the plastic buckle, and the plastic buckle is also provided with belt holes on the left and right sides of the U-shaped clip groove, and the plastic buckle can be slidably hung on the elastic band through the belt holes on the left and right sides.

[0011] When the nasogastric feeding device of the utility model is used, the improved gastric tube is inserted into the stomach through the patient's nasal cavity, the gastric tube fixer is tied and sleeved on the patient's head, and the exposed tube body of the improved gastric tube is clamped on the gastric tube fixer for fixing, the nasogastric feeding liquid is poured into the feeding bottle type infusion device, and then the tube joint of the improved gastric tube is connected and installed on the infusion nozzle of the feeding bottle type infusion device, and the feeding bottle type infusion device can be used to perform nasogastric infusion on the patient. Since the feeding bottle type infusion device does not have the problem of difficulty in performing suction and push injection operations due to contamination of the piston during the reuse operation of the syringe type infusion device, and the improved gastric tube is used, which is shorter than the conventional gastric tube and thus has less resistance, the entire nasogastric feeding operation process only needs to simply squeeze the bottle body of the feeding bottle type infusion device, which is simple, convenient, and labor-saving to operate, and there is no obvious difference in the difficulty of operation between repeated use and first use, and the feeding bottle type infusion device can be reused many times to save resources. In addition, the bottle-type infuser can obtain a larger infusion capacity at one time than the syringe-type infuser, and often only one filling is enough for the nasogastric feeding liquid for one meal. Moreover, the bottle-type design of the bottle-type infuser can bring more sensory comfort to the patient than the syringe-type infuser, which helps the patient relax while eating.

DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings.

[0021] like Figure 1-7 As shown, the nasogastric feeding device of the utility model comprises a feeding bottle-type infuser 1, an improved gastric tube 2 and a gastric tube fixer 3.

[0022] The bottle-type infuser 1 is provided with an infusion head 1.1 and an infusion bottle 1.2; the infusion head 1.1 is made of food-grade hard plastic material, the lower part of the infusion head 1.1 is an internally threaded bottle cap that matches the bottle mouth of the infusion bottle 1.2, the top surface of the bottle cap is provided with a frustum-shaped infusion nozzle 1.11 that protrudes upward and is connected to the inner side of the bottle cap, the inner side of the bottle cap is provided with a screw hole seat at a position corresponding to the opening of the infusion nozzle 1.11, a mesh filter 1.3 is installed on the screw hole seat, and the top surface of the bottle cap is also provided with a vent hole that runs through the inner and outer sides of the bottle cap beside the infusion nozzle 1.11 The vent seat 1.12 has an outer port extending from the vent seat 1.12 to the outside of the bottle cap, and is equipped with an openable plug cover 1.4; the vent seat 1.12 has an inner port extending from the vent seat 1.12 to the inside of the bottle cap, and is equipped with an air intake valve 1.5 for controlling one-way air intake inwards; the filling bottle 1.2 is made of food-grade soft plastic material, and is provided with a bottle mouth and a bottle body, and the filling bottle 1.2 is screwed onto the bottle cap of the filling head 1.1 through the screw threads on the outer circumference of the bottle mouth, and the bottle body is a transparent thin wall that can be squeezed and elastically deformed, and the outer side of the bottle body is provided with scale lines and capacity markings corresponding to the scale lines.

[0023] As a preferred technical solution, the mesh filter 1.3 is a cylindrical screen basket with mesh holes on the side walls and the bottom surface, and the outer circumference of the upper part of the screen basket is provided with screw threads matching the screw hole seat of the filling head 1.1.

[0024] As a preferred technical solution, the air inlet valve 1.5 is a cylindrical silicone sleeve fixedly sleeved on the inner port of the vent seat 1.12, the lower part of the silicone sleeve is designed to be a closed wedge-shaped tip, and a narrow slit 1.51 is opened along the tip of the wedge-shaped tip. When the pressure in the perfusion bottle 1.2 is negative, the narrow slit 1.51 can be opened to inhale air from the outside, and when the pressure in the perfusion bottle 1.2 is positive, the wedge-shaped tip can be squeezed to close the narrow slit 1.51, and the air cannot be exhausted outward through the narrow slit 1.51, thereby achieving one-way air intake.

[0025] As a preferred technical solution, the top surface of the bottle cap of the filling head 1.1 is provided with a plug cover fixing pile 1.13 beside the vent seat 1.12, and the plug cover 1.4 is provided with a soft tape connected to the plug cover fixing pile 1.13 so that the plug cover 1.4 can still be hung on the bottle cap when it is opened.

[0026] As a preferred technical solution, the pouring nozzle 1.11 of the pouring head 1.1 is equipped with a plug-in cover (not shown in the drawings) so that the cover can be inserted on the pouring nozzle 1.11 when the feeding bottle type pourer 1 is not in use to keep the pouring nozzle 1.11 clean.

[0027] As a preferred technical solution, the bottle body of the infusion bottle 1.2 is designed to be ellipsoidal, the bottle body capacity is 200 ml, the side of the bottle body with the capacity mark is the front side of the bottle body, and the wall thickness on the front and back sides of the bottle body is thinner than the wall thickness on the left and right sides, so that the infusion bottle 1.2 is easier to deform and more labor-saving when squeezed from the front and back sides.

[0028] The tube body of the improved gastric tube 2 is 80 cm long, and the rear end of the tube body is connected to an inverted cone-shaped tube joint 2.1 that matches the irrigation nozzle 1.11. Furthermore, the tube body of the improved gastric tube 2 is marked with scales, and the scales are marked backwards from 15 cm away from the front end of the tube body. Since the distance from the nostril to the throat of an adult is 14 to 16 cm, when the tube body of the improved gastric tube 2 is inserted to the beginning of the scale marking, it can be considered that the tube head has been inserted from the nostril to the throat, while the scales of the conventional gastric tubes currently used are marked from 25 cm away from the front end of the tube body, and the tube head can only be estimated by the approximate distance to be inserted into the throat, which is not convenient to use.

[0029] The stomach tube fixer 3 is provided with an elastic band 3.1, and the two ends of the elastic band 3.1 are respectively provided with Velcro pieces 3.2 that can be bonded to each other. A plastic buckle 3.3 that can slide and shift along the band body is hung in the middle of the band body of the elastic band 3.1; a U-shaped clip groove that matches the tube body of the improved stomach tube 2 is provided in the middle of the plastic buckle 3.3, and the plastic buckle 3.3 is also provided with belt holes on the left and right sides of the U-shaped clip groove. The plastic buckle 3.3 can be slidably hung on the elastic band 3.1 through the belt holes on its left and right sides.

[0030] As a preferred solution, three plastic buckles 3.3, namely left, middle and right, are hung on the middle of the elastic band 3.1 to facilitate fixing the exposed tube body of the improved gastric tube 2.

[0031] The method of using this nasogastric feeding device is as follows:

[0032] (1) Insert the head of the modified gastric tube 2 through the nostril to the start of the scale mark, that is, the tube head has been inserted from the nostril to the throat, and then ask the patient to swallow. When the patient swallows, the tube body of the modified gastric tube 2 is pushed forward until it reaches the predetermined scale.

[0033] (2) The elastic band 3.1 of the gastric tube fixer 3 is attached to the patient's head through the Velcro pieces 3.2 at both ends, and the position of the middle plastic buckle 3.3 is adjusted so that it is placed just below the patient's nostril where the tube is inserted, with the U-shaped clip groove of the plastic buckle 3.3 facing outward. The tube body of the improved gastric tube 2 is fixed at a predetermined scale position in the U-shaped clip groove of the middle plastic buckle 3.3. The exposed part of the tube body of the improved gastric tube 2 is bent into a U shape and fixed in the U-shaped clip groove of the left or right plastic buckle 3.3 (the plastic buckle 3.3 on the same side as the nostril where the gastric tube is inserted is selected for U-shaped fixing).

[0034] (3) Close the vent seat 1.12 of the empty baby bottle type perfuser 1 with the plug cover 1.4, squeeze the perfusion bottle 1.2 of the baby bottle type perfuser 1 to discharge the internal air from the perfusion nozzle 1.11, then connect the pipe joint 2.1 of the improved gastric tube 2 with the perfusion nozzle 1.11 of the baby bottle type perfuser 1 and release the perfusion bottle 1.2, and use the negative pressure of the baby bottle type perfuser 1 to perform suction. When it is observed that the gastric juice is sucked back to the exposed part of the improved gastric tube 2, thereby confirming that the front end of the tube body of the improved gastric tube 2 is already in the stomach, the baby bottle type perfuser 1 can be disassembled to prepare for nasogastric perfusion operation.

[0035] (4) Unscrew the infusion head 1.1 of the baby bottle infusion set 1 from the infusion bottle 1.2, stand the infusion bottle 1.2 on a flat surface, pour an appropriate amount of nasogastric feeding fluid of suitable temperature into the infusion bottle 1.2, then open the plug cover 1.4 on the vent seat 1.12 of the infusion head 1.1, and choose whether to remove the mesh filter 1.3 behind the infusion nozzle 1.11 according to the condition of the nasogastric feeding fluid (the mesh filter 1.3 can filter the food with larger particles in the nasogastric feeding fluid to prevent it from clogging the gastric tube, but adding the mesh filter 1.3 will increase the flow resistance of the nasogastric feeding fluid. Whether to use the mesh filter 1.3 can be selected according to the degree of grinding of the nasogastric feeding fluid). Then, install the infusion head 1.1 back on the infusion bottle 1.2 and tighten it, and connect the pipe joint 2.1 of the improved gastric tube 2 with the infusion nozzle 1.11 of the baby bottle infusion set 1, and then nasogastric feeding can be performed. During the infusion process, the bottom of the infusion bottle 1.2 is at a high position, and the infusion nozzle 1.11 is at a low position. Gravity is used to allow the nasogastric feeding liquid to flow into the improved gastric tube 2 and reach the stomach. At the same time, the nasogastric feeding can be easily completed by gently squeezing the body of the infusion bottle 1.2.

[0036] The above-mentioned figures are only typical embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
