Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a nutrition pipeline. Background Art

[0002] When critically ill patients receive enteral nutrition, the gastrointestinal nutrition tube inserted into the patient's stomach or jejunum through the patient's mouth / nasal cavity is an important enteral nutrition feeding channel. It connects to an external nutrition infusion line to deliver various required liquid nutrients or drugs to the patient's gastrointestinal tract to maintain the patient's vital signs.

[0003] There are two ways to connect the gastrointestinal nutrition tube to the nutrition infusion line. One is to use a 6% Luer conical connector (refer to GB1962). Usually, the nutrition infusion line is a 6% male Luer connector, and the connector of the gastrointestinal nutrition tube is an internal conical connector that can be tightly matched with the 6% male Luer connector. The other is a stepped interface connection (also called Funnel connector, refer to YY0483), that is, a stepped interface is configured on the nutrition infusion line, and the connector on the gastrointestinal nutrition tube is a conical connector that can be tightly matched with the stepped interface.

[0004] The connectors of gastrointestinal nutrition tubes on the market are usually designed according to the requirements of YY0483. In clinical use, if you encounter a nutrition infusion line with a 6% male Luer connector, you need to connect it with an adapter, which is relatively cumbersome and requires an additional adapter component; some gastrointestinal nutrition tubes have connectors designed to fit the inner cone structure of the 6% male Luer connector, and are equipped with an adapter that matches the stepped interface. When connecting the nutrition infusion line, although there is no need to use an additional adapter, the operation steps are not simplified, and the number of parts of the product increases, resulting in an increase in the manufacturing cost of the gastrointestinal nutrition tube. Summary of the invention

[0005] The object of the present invention is to provide a nutrition pipeline to solve the problem of incompatibility of interfaces of existing nutrition pipelines.

[0006] In order to solve the above technical problems, the present invention provides a nutrition pipeline, including a multifunctional input pipeline and an output pipeline, the multifunctional input pipeline and the output pipeline are connected to each other, the multifunctional input pipeline is provided with a stepped interface, and the stepped interface can be stored in the form of surrounding the side of the multifunctional input pipeline. When the stepped interface is in the stored state, the multifunctional input pipeline exposes a female Luer interface.

[0007] In one embodiment, the nutrition pipeline is further provided with a single-function pipeline, the single-function pipeline is connected to the output pipeline, and the single-function pipeline is provided with a female Luer interface or a stepped interface.

[0008] In one embodiment, the multifunctional input pipeline and the single-functional pipeline are arranged on the same side of the nutrition pipeline, and there is an acute angle between the multifunctional input pipeline and the single-functional pipeline.

[0009] In one embodiment, the multifunctional input pipeline is connected to the output pipeline as a straight pipeline.

[0010] In one embodiment, the circumference of the multifunctional input pipeline is surrounded by a foldable film sleeve, the port of the film sleeve is provided with the stepped interface, and the film sleeve can be folded and put on the outside of the tube wall of the multifunctional input pipeline so that the stepped interface is surrounded by the outside of the tube wall of the multifunctional input pipeline.

[0011] In one embodiment, the diameter of the membrane bushing on the side close to the stepped interface is larger than the diameter of the membrane bushing on the side away from the stepped interface.

[0012] In one embodiment, the hardness of the stepped interface is greater than the hardness of the membrane bushing.

[0013] In one embodiment, the outer wall of the multifunctional input pipeline is provided with an external thread, the outer wall of the multifunctional input pipeline is threadedly connected with a rotating sleeve, the port of the rotating sleeve is provided with the stepped interface, and the rotation of the rotating sleeve is used to extend the stepped interface and retract the stepped interface to a state of surrounding the multifunctional input pipeline.

[0014] In one embodiment, the outer wall of the multifunctional input pipeline is provided with a receiving groove, and the receiving groove is arranged around the pipe wall of the multifunctional input pipeline. A pipe sleeve that can enter and exit is installed in the receiving groove, and the port of the pipe sleeve is provided with the stepped interface. The pipe sleeve is used to extend the stepped interface and retract the stepped interface to a state of surrounding the multifunctional input pipeline.

[0015] The beneficial effects of the present invention are as follows:

[0016] Since the multifunctional input pipeline is provided with a stepped interface, when it needs to be matched with a tower connector, the tower connector can be directly inserted into the stepped interface for use; and since the stepped interface can be stored in the form of surrounding the side of the multifunctional input pipeline, when the stepped interface is in the stored state, the multifunctional input pipeline reveals a female Luer interface, so when it needs to be matched with a male Luer connector, it is only necessary to store the stepped interface first, and then the male Luer connector can be inserted into the female Luer interface for use; that is, the present invention does not require the purchase of additional conversion connectors, which provides great convenience for the work of medical staff.

[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0036] The first embodiment of the nutrition pipeline of the present invention is as follows Figure 1 and Figure 2 As shown, it includes a multifunctional input pipeline 11 and an output pipeline 12. The multifunctional input pipeline 11 and the output pipeline 12 are connected to each other. The multifunctional input pipeline 11 is provided with a stepped interface 21. The stepped interface 21 can be stored in the form of surrounding the side of the multifunctional input pipeline 11. When the stepped interface 21 is in the stored state, the multifunctional input pipeline 11 reveals a female Luer interface 22.

[0037] When it is necessary to match with a tower connector, the storage state of the step interface 21 can be released, and then the tower connector can be inserted into the step interface 21; when it is necessary to match with a male Luer connector, the step interface 21 can be first stored outside the wall of the multi-functional input pipeline 11, so that the female Luer connector 22 can be exposed, and finally the male Luer connector can be inserted into the female Luer connector 22.

[0038] That is, when medical staff apply the present invention, they do not need to prepare additional conversion joints, and the nutrition pipeline itself already has the interface conversion function, which provides great convenience for the work of medical staff.

[0039] A second embodiment of the nutrition circuit of the present invention is as follows Figure 3 As shown, it is basically the same as the first embodiment, except that the nutrition pipeline is further provided with a single-function pipeline 13, the single-function pipeline 13 and the output pipeline 12 are mutually conductive, and the single-function pipeline 13 is provided with a female Luer interface 22.

[0040] That is, during application, a variety of working states can be realized, such as connecting the single-function pipeline 13 with the male Luer connector, connecting with the tower connector through the multi-function input pipeline 11, or connecting with the male Luer connector using the multi-function input pipeline 11, thereby further improving the application scope of the nutrition pipeline.

[0041] It should be pointed out that the single-function pipeline 13 is not only used to set the female Luer interface 22, but can also be used to set the stepped interface 21, that is, the single-function pipeline 13 can be set with a female Luer interface 22 or a stepped interface 21, and the designer can choose according to specific needs.

[0042] A third embodiment of the nutrition circuit of the present invention is as follows Figure 4 As shown, it is basically the same as the second embodiment, except that the multifunctional input pipeline 11 and the single-functional pipeline 13 are arranged on the same side of the nutrition pipeline, and there is an acute angle between the multifunctional input pipeline and the single-functional pipeline 13.

[0043] This setting method makes it easy to concentrate the input in the same direction, providing convenience for medical staff's operation. In addition, there is an acute angle between the multifunctional input pipeline 11 and the single-function pipeline 13, which not only avoids contact and entanglement between different joints, but also improves the structural compactness of the nutrition pipeline.

[0044] A fourth embodiment of the nutrition circuit of the present invention is Figure 5 As shown, it is basically the same as the third embodiment, the difference is that the multifunctional input pipeline 11 and the output pipeline 12 are connected as a straight pipeline. The advantage of this arrangement is that it ensures optimal fluidity between the multifunctional input pipeline and the output pipeline 12, thereby avoiding blockage due to pipeline bending.

[0045] A fifth embodiment of the nutrition circuit of the present invention is Figure 6 As shown, it is basically the same as the fourth embodiment, with the difference that the circumferential side of the multifunctional input pipeline 11 is surrounded by a foldable film bushing 30, the port of the film bushing 30 is provided with a stepped interface 21, and the film bushing 30 can be folded and put on the outside of the tube wall of the multifunctional input pipeline 11 so that the stepped interface 21 is surrounded by the outside of the tube wall of the multifunctional input pipeline 11.

[0046] Since the film sleeve 30 is made of a flexible material, the film sleeve 30 can be folded at will. Therefore, after the film sleeve 30 is folded inward, the film sleeve 30 will be sleeved outside the tube wall of the multi-functional input pipeline 11. Therefore, driven by the film sleeve 30, the stepped interface 21 will also move and sleeved outside the tube wall of the multi-functional input pipeline 11, thereby realizing the exposure of the female Luer interface 22.

[0047] A sixth embodiment of the nutrition circuit of the present invention is Figure 7 As shown, it is basically the same as the fifth embodiment, the difference is that the diameter of the film bushing 30 close to the stepped interface 21 is larger than the diameter of the film bushing 30 away from the stepped interface 21, so the film bushing 30 will be roughly conical at this time. The advantage of this structure is that the space of the film bushing 30 is expanded, so that the process of folding and storing the film bushing 30 is easier, thereby improving the user experience of medical staff.

[0048] The seventh embodiment of the nutrition pipeline described in the present invention is basically the same as the sixth embodiment, with the difference that the hardness of the stepped interface 21 is greater than the hardness of the film sleeve 30. The advantage of this embodiment is that it will not hinder the folding operation of the film sleeve 30, but at the same time it can enhance the hardness of the stepped interface 21, ensuring that the stepped interface 21 can be securely connected to the tower joint.

[0049] The eighth embodiment of the nutrition pipeline of the present invention is Figure 8 and Fig. 9 As shown, it is basically the same as the first embodiment, the difference is that the outer wall of the multifunctional input pipeline 11 is provided with an external thread 111, the outer wall of the multifunctional input pipeline 11 is threadedly connected with a rotating sleeve 40, the port of the rotating sleeve 40 is provided with a stepped interface 21, and the rotation of the rotating sleeve 40 is used to extend the stepped interface 21 and retract the stepped interface 21 to a state of surrounding the multifunctional input pipeline 11.

[0050] At this time, the stepped interface 21 is arranged at the upper end of the rotating sleeve 40. Since the inner wall of the rotating sleeve 40 is provided with an internal thread, the rotating sleeve 40 can be threadedly connected to the pipe wall of the multi-functional input pipeline 11, that is, the stepped interface 21 can be moved upward by rotating the rotating sleeve 40 to facilitate the matching application of the tower connector, or the stepped interface 21 can be controlled to move downward by rotating the rotating sleeve 40 to directly expose the female Luer interface 22 for matching application with the male Luer connector.

[0051] The ninth embodiment of the nutrition circuit of the present invention is as follows Fig.10 and Fig.11 As shown, it is basically the same as the first embodiment, with the difference that the outer wall of the multifunctional input pipeline 11 is provided with a receiving groove 112, and the receiving groove 112 is arranged around the pipe wall of the multifunctional input pipeline 11, and a pipe sleeve 50 capable of entering and exiting is installed in the receiving groove 112, and a stepped interface 21 is provided at the port of the pipe sleeve 50, and the pipe sleeve 50 is used to extend the stepped interface 21 and retract the stepped interface 21 to a state of surrounding the multifunctional input pipeline 11.

[0052] At this time, the stepped interface 21 is arranged at the upper end of the tube sleeve 50. Since the tube sleeve 50 can move up and down in the storage groove 112, when the tube sleeve 50 moves upward, the stepped interface 21 can be matched with the tower connector. Similarly, by moving the tube sleeve 50 downward, the stepped interface 21 will move downward and expose the female Luer interface 22, thereby facilitating the matching of the female Luer interface 22 with the male Luer connector.

[0053] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
