Description

Technical Field

[0001] This utility model relates to the field of medical consumables technology, specifically an integrated syringe for nasogastric feeding pumps for premature infants. Background Technology

[0002] Existing nasogastric feeding pumps for premature infants are cumbersome because the feeding tubes are very short. The syringe typically consists of a regular syringe and an IV extension tubing. The required amount of milk must first be drawn with the syringe, connected to the IV extension tubing, drained, and then connected to the feeding tube. After the injection, the syringe must be removed, warm water drawn, and the extension tubing reconnected for flushing to obtain the desired amount of milk. Furthermore, the connection between the IV extension tubing and the feeding tube requires folding the feeding tube cap backwards, which can easily break with frequent nasogastric feeding pumping, and the feeding tube cap may not close properly. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an integrated syringe specifically designed for nasogastric feeding pumps for premature infants, solving the current problems associated with nasogastric feeding pumps for premature infants.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: an integrated syringe for feeding milk via nasogastric tube for premature infants, comprising a syringe and an extension tube integrally connected to the liquid outlet end, the other end of the extension tube being inserted into the nasogastric tube for premature infants, and the syringe or the extension tube being provided with a flushing structure for flushing the tube, wherein the flushing structure on the syringe is air flushing and the flushing structure on the extension tube is warm water flushing.

[0005] Preferably, the extension tube is a telescopic plastic tube, and the outer diameter of the end of the extension tube away from the syringe is smaller than the inner diameter of the end of the nasogastric tube for premature infants.

[0006] Preferably, the syringe includes a syringe barrel and a piston rod inside it.

[0007] Preferably, the flushing structure on the extension tube is a short tube connected to the side of the extension tube near the syringe, and the movable end of the short tube is provided with a rubber stopper, which is injected by piercing the rubber stopper with the syringe needle.

[0008] Preferably, the syringe has a piston rod structure, which includes an outer push tube. The bottom end of the outer push tube is fitted with a main rubber plug that fits against the inner wall of the syringe. The bottom ends of the outer push tube and the main rubber plug are connected at their centers. An air inlet is provided on the side of the outer push tube above the main rubber plug. An inner push tube is slidably disposed inside the outer push tube. A secondary rubber plug is fitted on the bottom end of the inner push tube. When the inner push tube is pressed down to its lowest point, the secondary rubber plug closes the air inlet or is located below the air inlet. The top ends of both the outer push tube and the inner push tube are pressed outward to form a flat handle.

[0009] Preferably, the outside of the push tube is covered with filter cotton that covers the air inlet.

[0010] This invention provides an integrated nasogastric feeding pump syringe specifically designed for premature infants. Compared with existing technologies, it offers the following advantages:

[0011] 1. The integrated nasogastric feeding pump syringe for premature infants in Example 1 connects the extension tube to the syringe in one piece and sets the extension tube to a self-expanding structure, making it convenient for storage and packaging. It can be stretched and used at will, which is more convenient than existing infusion extension tubes. Furthermore, by directly connecting the short tube to the side of the extension tube, warm water can be injected directly to flush the tube without removing the syringe, reducing the workload of medical staff and making it easy to use. At this time, there is no need to fold the nasogastric tube, avoiding the problem of breakage caused by frequent bending.

[0012] 2. The integrated nasogastric feeding pump syringe for premature infants in Example 2 is achieved by modifying an existing syringe. The piston rod is designed as a double-tube design with inner and outer tubes. When the entire syringe is pushed in, the piston rod end is closed, allowing for normal pressurization and milk extraction. When flushing is needed, the inner tube is pulled out to connect the end of the outer tube with the air inlet. Pulling out the outer tube allows air to enter the syringe through the air inlet. Pushing the inner tube again allows air to flush the milk in the extension tube. The filter cotton outside the air inlet also filters the air. During this process, the piston rod acts as a valve. The structure is relatively simple, and the step of injecting warm water is eliminated. The appearance of the syringe is not significantly different from the existing structure, and it can be installed normally on the injection pump.

[0013] In summary, this application provides two types of integrated nasogastric feeding pump syringes for premature infants, which can meet different cost and usage needs. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] See Figures 1-4 This utility model provides the following two technical solutions:

[0022] Figure 1 The first embodiment is shown: an integrated nasogastric feeding pump syringe for premature infants, including a syringe 1 and an extension tube 2 integrally connected to its liquid outlet end. The syringe 1 includes a syringe barrel 11 and a piston rod 12 inside, which is the structure of a conventional syringe. The other end of the extension tube 2 is inserted into the nasogastric feeding tube for premature infants. The extension tube 2 is provided with a flushing structure for flushing the tube, and the flushing structure uses warm water for flushing.

[0023] The extension tube 2 is a telescopic plastic tube, and the outer diameter of the end of the extension tube 2 away from the syringe 1 is smaller than the inner diameter of the docking end of the premature infant nasogastric tube, and the front end is smaller than the diameter of the nasogastric tube. This can prevent the tube from being wrapped around the outside of the nasogastric tube, which would cause the connecting strap between the nasogastric tube and the nasogastric tube cap to break.

[0024] The flushing structure on the extension tube 2 is a short tube 21 connected to the side of the extension tube 2 near the syringe 1, and a rubber stopper 22 is provided inside the movable end of the short tube 21. The injection flushing is performed by piercing the rubber stopper 22 with the syringe needle.

[0025] By integrating the extension tube 2 with the syringe 1 and setting the extension tube 2 as a self-expanding structure, it is convenient to store and package, and can be stretched and used at will. It is more convenient to use than existing infusion extension tubes. Furthermore, by directly connecting the short tube 21 to the side of the extension tube 2, warm water can be injected directly to flush the tube without removing the syringe 1, which reduces the workload of medical staff and is convenient to use. At this time, there is no need to fold the nasogastric tube, avoiding the problem of breakage caused by frequent bending.

[0026] Figures 2-4 The second embodiment is shown: it includes a syringe 1 and an extension tube 2 integrally connected to its liquid outlet end. The syringe 1 includes a syringe barrel 11 and a piston rod 12 inside it. The other end of the extension tube 2 is inserted into a nasogastric feeding tube for premature infants. The syringe 1 is provided with a flushing structure for flushing the tube, and the flushing structure adopts air flushing.

[0027] The extension tube 2 is a telescopic plastic tube, and the outer diameter of the end of the extension tube 2 away from the syringe 1 is smaller than the inner diameter of the connecting end of the premature infant nasogastric tube.

[0028] The punching structure is a piston push rod 12, which includes an outer push tube 121. The bottom end of the outer push tube 121 is fitted with a main rubber plug 122 that fits against the inner wall of the syringe 11. The bottom ends of the outer push tube 121 and the main rubber plug 122 are connected. An air inlet 123 is provided on the side of the outer push tube 121 and above the main rubber plug 122. An inner push tube 124 is slidably arranged inside the outer push tube 121. A secondary rubber plug 125 is fitted on the bottom end of the inner push tube 124. When the inner push tube 124 is pressed down to the lowest end, the secondary rubber plug 125 closes the air inlet 123 or is located below the air inlet 123. The top ends of the outer push tube 121 and the inner push tube 124 are both pressed outward to form a flat handle. A filter cotton 126 covering the air inlet 123 is fitted on the outside of the outer push tube 121.

[0029] In this embodiment, by modifying the existing syringe, the piston rod 12 is set as a double tube with inner and outer tubes. When the whole is pushed in, the end of the piston rod 12 is closed, and milk can be squeezed out under normal pressure. When flushing is needed, the inner tube 124 is pulled out to connect the end of the outer tube 121 with the air inlet 123. At this time, pulling out the outer tube 121 allows air to enter the syringe 11 from the air inlet 123. When the inner tube 124 is pushed again, the milk in the extension tube 2 can be flushed by air. The filter cotton 126 outside the air inlet 123 also plays the role of filtering air. In this process, the piston rod 12 acts as a valve, and the structure is relatively simple. It also eliminates the step of injecting warm water. The appearance of the entire syringe 1 is not significantly changed compared to the existing structure, and it can be installed normally on the injection pump.
