Description

Technical Field

[0001] The utility model relates to a liquid food delivery tube, in particular to a liquid food delivery tube which adopts an inner support to prevent blocking. Background Art

[0002] The main function of the liquid food delivery tube for tumor gastrointestinal care is to open the top cap of the gastric tube and slowly push in liquid food or water with a small 60ml syringe. The gastric tube is used to help patients who cannot swallow to deliver necessary water and food under special circumstances. It is divided into oral gastric tube and nasogastric tube. There are generally two joints for the feeding port of the gastric tube. The top cap can only be opened with a small syringe to manually pressurize the push rod and piston to inject some liquid food like water. The booster and 100ml large syringe can be used to inject some thicker meat and vegetable foam or mechanically crushed into paste or noodles, etc., which can increase dietary fiber, facilitate defecation, promote digestion and nutrition supply, but cannot feed too much and too fast at one time, which will lead to poor gastric emptying and esophageal reflux. The liquid food delivery tube for tumor gastrointestinal care is difficult to clear after being blocked, and the joint of the liquid food delivery tube for tumor gastrointestinal care adopts an integrated structure, which is difficult to clear twice.

[0003] The joints of the liquid food delivery tubes for tumor gastrointestinal care on the market are usually an integrated structure, which is difficult to connect and install a second time. Due to the integrated structure, the delivery tube needs to be shortened during the unblocking process. At the same time, during the use of the delivery tube, due to changes in angles, etc., it is easy to cause internal folding and lead to blockage of liquid food. The length of the blockage is limited, making it difficult to unblock or extend and adjust. Summary of the invention

[0004] The purpose of the utility model is to overcome the defects in the prior art and provide a device which can avoid the blockage of liquid food, is easy to use and prevents

[0005] The utility model is implemented as follows: a liquid food delivery tube adopting an inner support to prevent blocking comprises a delivery tube, an inner support tube, a telescopic tube, an extension tube, a first joint tube, a second joint tube and a liquid food injection tube, wherein the inner support tube is sleeved and fixed on the delivery tube, and one end of the inner support tube and one end of the delivery tube are commonly connected to one end of the telescopic tube, and the other end of the telescopic tube is connected to one end of the extension tube; the other end of the extension tube is connected to the first joint tube; the first joint tube and the second joint tube are pluggably connected, and the second joint tube is connected to the liquid food injection tube.

[0006] A circle of evenly distributed convex teeth is arranged on the outer wall of the end of the first joint pipe, and a groove matching with the convex teeth is arranged on the inner wall of the second joint pipe; the convex teeth and the groove are tightly matched.

[0007] The cross section of the protruding tooth is triangular.

[0008] The top and bottom of the extension tube are respectively flat.

[0009] The length of the extension tube is 8 cm to 10 cm; the length of the inner support tube is 9 cm to 10 cm.

[0010] The inner support tube is a rubber support tube or a silicone support tube.

[0011] The telescopic tube is a corrugated rubber tube.

[0012] The beneficial effects of the utility model are as follows: by arranging a pluggable connection between the first joint tube and the second joint tube at the part of the pipeline that is most prone to clogging, when the pipeline is blocked, the pipeline can be unblocked by removing the second joint tube, thus avoiding the pipe cutting operation and facilitating use; the inner support tube prevents the pipeline from being blocked due to bending of the delivery pipe; through the telescopic tube, the user can manually pull the telescopic tube to elastically expand the telescopic tube to extend the length of the connecting end pipe and expand the conveying space of the connecting end pipe, thereby making it easier to unblock the part that is prone to clogging and avoiding blockage and accumulation of liquid food in the telescopic tube and the extension tube.

[0018] according to Figure 1-Figure 4The utility model is a liquid food delivery tube with internal support and anti-blocking, comprising a delivery tube 1, an internal support tube 2, a telescopic tube 3, an extension tube 4, a first joint tube 5, a second joint tube 6 and a liquid food injection tube 7. The internal support tube 2 is sleeved and fixed on the delivery tube 1, and one end of the internal support tube 2 and one end of the delivery tube 1 are connected to one end of the telescopic tube 3, and the other end of the telescopic tube 3 is connected to one end of the extension tube 4; the other end of the extension tube 4 is connected to the first joint tube 5; the first joint tube 5 and the second joint tube 6 are pluggable and connected, and the second joint tube 6 is connected to the liquid food injection tube 7. A circle of evenly distributed convex teeth 8 is provided on the outer wall of the end of the first joint tube 5, and a groove 9 matched with the convex teeth 8 is provided on the inner wall of the second joint tube 6; the convex teeth 8 and the groove 9 are tightly matched, and the pluggable connection is achieved through the convex teeth 8 and the groove 9.

[0019] The cross section of the protruding tooth 8 is triangular.

[0020] The top and bottom of the extension tube 4 are respectively flat, and the extension tube 4 has a square outer and round inner structure, which can better prevent extrusion deformation, and is more convenient for hand-held operations such as connecting the pipe, so that the easily blocked part can be opened and unblocked. The length of the extension tube 4 is 8cm~10cm, preferably 9cm. The length of the inner support tube 2 is 9cm~10cm, preferably 9cm. The inner support tube 2 is a rubber support tube or a silicone support tube; the inner support tube 2 can prevent the pipeline from being blocked due to bending of the delivery pipe.
