Description

Technical Field

[0001] The utility model relates to the technical field of medical adapters, in particular to a nasogastric tube adapter for optimizing feeding. Background Art

[0002] Nasogastric tube technology is a routine nursing measure to solve digestive tract problems. It is used to provide gastrointestinal decompression, enteral nutrition, and intragastric drug infusion to patients of all ages. Since the nasogastric tube has a single opening, when the patient needs gastrointestinal decompression and nasogastric feeding, drug injection, etc., the gastrointestinal decompression must be separated first, or the nasogastric tube must be clamped after the feeding and drug injection are completed. The separation of gastrointestinal decompression can easily cause environmental pollution; long-term clamping of the nasogastric tube can easily cause the tube to bend and difficult to recover. At the same time, the cap of the connector of the ordinary nasogastric tube is very easy to loosen, causing gastric contents to reflux and pollute the environment.

[0003] Therefore, a nasogastric tube conversion head for optimizing feeding is needed to solve the above technical problems. Utility Model Content

[0023] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0024] like Figure 1 - Figure 5 As shown, a nasogastric tube conversion head for optimizing feeding includes a shell 1, which is made of a transparent material. The exterior of the shell 1 is cylindrical, and the side of the shell 1 is connected to a gastric tube connector 2 and a negative pressure box connector 3. A piston rod 4 is inserted into one end of the shell 1, and the other end of the shell 1 is closed, and the negative pressure box connector 3 is located at the closed end. During the process of inserting the shell 1, the piston rod 4 first passes through the gastric tube connector 2 and then passes through the negative pressure box connector 3. The front end of the piston rod 4 is sealed and slidably connected to the inner wall of the shell 1. An L-shaped channel is provided inside the piston rod 4, and the two ends of the L-shaped channel are respectively an inlet 5 and an outlet 6, and the outlet 6 faces the side of the gastric tube connector 2.

[0025] The inner cavity cross section of the housing 1 is elliptical, and the outer contour of the cross section of the piston rod 4 is elliptical, which prevents the piston rod 4 from rotating in the housing 1.

[0026] like Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 As shown, the inner side wall of the open end of the housing 1 is axially provided with a chute 7. It should be noted that the chute 7 cannot extend to the position of the gastric tube connector 2. The chute 7 is provided with three triangular slots 9, which are equidistantly arranged. A triangular block 11 is slidably connected to the side wall of the piston rod 4. The front end of the triangular block 11 is adapted to the triangular slots 9, and the rear end of the triangular block 11 is slidably connected to the piston rod 4. Specifically, a guide cavity 10 is provided on the side wall of the piston rod 4. The rear end of the triangular block 11 is embedded in the guide cavity 10. The front end of the guide cavity 10 is provided with an anti-disengagement ring to prevent the triangular block 11 from disengaging from the piston rod 4. The outer sleeve of the triangular block 11 is provided with a spring 12, and the two ends of the spring 12 are respectively abutted against the piston rod 4 and the triangular block 11. The outside of the housing 1 is provided with three gear marks "slow", "medium" and "fast" from bottom to top. The three gear marks are arranged at the height positions of the three triangular slots 9 in sequence.

[0027] like Figure 1As shown, when the triangular block 11 is inserted into the middle triangular slot 9, the flow rate is in the "medium" gear, and the overlapping area of ​​the outlet 6 and the gastric tube connector 2 is an effective circulation channel. Food or medicine enters from the inlet 5 and enters the gastric tube through the gastric tube connector 2, while the channel of the negative pressure box connector 3 is blocked by the front end of the piston rod 4. At this time, the patient can be fed through the nose normally. When the flow rate needs to be adjusted, the piston rod 4 is pushed forward, and the head end of the triangular block 11 slides along the inclined surface of the triangular slot 9, and the spring 12 retracts. When the triangular block 11 enters the other triangular slot 9, the overlapping area of ​​the outlet 6 and the gastric tube connector 2 increases, which corresponds to the "fast" gear flow rate (such as Figure 4 When the triangular block 11 is located in the first triangular slot 9 at the lower end, the gear is "slow," and the feeding channel is at its smallest. As the piston rod 4 is pushed, the damping sensation changes with each entry of the triangular block 11 into each triangular slot 9. The spring force and the interaction force at the inclined surface cause the piston rod 4 to remain in a fixed position, ensuring that the flow channel size corresponding to each gear position remains uniform after each adjustment. Furthermore, the piston rod 4 feels better when pushed, helping to control the flow rate.

[0028] When performing gastrointestinal decompression on a patient, pull the piston rod 4 to the outermost end (such as Figure 5 As shown, the front end of the piston rod 4 blocks the L-shaped channel for nasogastric feeding, while the stomach tube connector 2 is connected to the negative pressure box connector 3, allowing gastrointestinal decompression of the patient. A sealing cap 13 is installed at the inlet 5. A rubber sealing ring is provided on the outside of the sealing cap 13, which fits tightly against the inner wall of the inlet 5, providing a seal and preventing the sealing cap 13 from falling off.

[0029] A stopper 8 is provided at one end of the chute 7, and the stopper 8 is fixedly connected to the housing 1 by a bolt. When the piston rod 4 needs to be removed, the bolt is removed and the piston rod 4 is pulled outward, thereby pushing out the stopper 8 and removing the piston rod 4. A step 14 is provided on the outer side of the end of the piston rod 4 to facilitate pulling the piston rod 4 outward.

[0030] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
