Description

Technical Field

[0001] This utility model relates to the field of bagged product technology, and in particular to a spout structure and bag assembly. Background Technology

[0002] Currently, hospitals use disposable special nutrition delivery devices to connect infusion bottles or bags to the nasogastric tube for patients who require nasogastric feeding, so as to deliver the medication or nutrition solution in the container to the patient.

[0003] The nutrition delivery device is a complete set of equipment, which typically includes components such as a sheath, nutrition tubing connector, tubing, flow regulator, drip chamber, and nutrition container connector. One end of the nutrition delivery device is used to connect to the bottom of the infusion bottle or infusion bag, and the other end is used to connect to the front end of the nasogastric tube. It can deliver the nutrient solution into the patient's body by gravity.

[0004] However, dedicated nutrient delivery devices need to be specially purchased, and due to their complex structure, they are not only more cumbersome to operate, but also have higher operating costs. Utility Model Content

[0005] The purpose of this utility model is to provide a suction nozzle structure and bag assembly to alleviate the technical problems existing in the prior art where a special nutrient delivery device is required to connect the infusion container to the nasogastric tube when using a disposable special nutrient delivery device. Furthermore, due to the complex structure of the special nutrient delivery device, the operation is not only cumbersome, but also the cost of use is high.

[0006] In a first aspect, this utility model provides a suction nozzle structure, including a mouth tube and a sealing film;

[0007] The outer wall of the tube is provided with an external thread, which is adapted to the internal thread of the inner wall of the threaded cap at the beginning of the external nutrition connector.

[0008] One end of the tube is connected to the opening of the outer container, and the other end is fixed with the sealing film. The sealing film is used to be punctured by the puncture needle on the threaded cap when the tube is threadedly connected to the threaded cap, so that the puncture needle can be inserted into the container.

[0009] In an optional embodiment, a groove-shaped outer cover is also included, which covers the mouth tube and the sealing film.

[0010] In an optional embodiment, the outer cover is detachably connected to the mouth tube.

[0011] In an optional embodiment, an annular base is fixedly connected to the end edge of the tube away from the sealing film, and the outer cover is snapped into the base.

[0012] In an optional embodiment, a retaining plate extending axially along the outer cover is provided at the edge of the slot of the outer cover, and a buckle is provided on the side of the retaining plate near the central axis of the outer cover.

[0013] The base has a limiting protrusion on its circumferential sidewall. The latch can extend into the side of the limiting protrusion away from the sealing film. The buckle is used to move to the side of the limiting protrusion when the outer cover rotates, so that the buckle and the limiting protrusion abut against each other along the axial direction of the outer cover.

[0014] In an optional embodiment, the circumferential sidewall of the outer cover is provided with a recess.

[0015] In an optional embodiment, there are two recesses, which are symmetrically arranged on both sides of the outer cover.

[0016] In an optional embodiment, the sealing film includes an adhesive portion and a holding portion, wherein the adhesive portion is fixed to the end opening of the tube, and the holding portion is connected to one side of the adhesive portion.

[0017] In an optional embodiment, the sealing film is made of a mixture of aluminum, polyester resin, nylon, and chlorinated polypropylene.

[0018] Secondly, this utility model provides a bag assembly, including the suction nozzle structure described in any of the foregoing embodiments.

[0019] The suction nozzle structure provided by this utility model includes a mouth tube and a sealing film. The outer wall of the mouth tube has an external thread, which is adapted to the internal thread of the threaded cap at the beginning of the external nutrition connector. One end of the mouth tube is connected to the container opening of an external container, and the other end is fixed with a sealing film. The sealing film is used to be punctured by a puncture needle inserted through the threaded cap when the mouth tube is threadedly connected to the threaded cap, so that the puncture needle can be inserted into the container. The suction nozzle structure provided by this utility model can be used in clinical operations such as nasogastric feeding that require the delivery of nutrient solutions or medications. The mouth tube in the suction nozzle structure can be fixed to the container opening of a container such as a soft bag through welding or integral molding. The container can be filled with nutrient solutions or medications. The sealing film needs to be fixed to the end of the mouth tube away from the container to seal the liquid inside the container. When nasogastric feeding or other clinical operations are required, existing nutrition connectors can be used to connect the container and the nasogastric tube. Specifically, existing nutrition connectors have a head end and a tail end, with the tail end connecting to a nasogastric tube and the head end equipped with a puncture needle. A threaded cap is fitted over and secured to the puncture needle. Because the suction nozzle structure provided by this invention has external threads on the outer wall of the mouthpiece and the sealing film can be punctured by the puncture needle, when connecting the mouthpiece to the nutrition connector, the puncture needle can first puncture through the sealing film and extend into a container such as a soft bag. Then, the threaded cap is threadedly connected to the mouthpiece. At this point, the threaded cap can be fixed outside the mouthpiece and provides stable support for the puncture needle, ensuring stable connection between the container and the nutrition connector. It should be noted that because existing nutrition connectors are used to connect nutrition bags, nutrition tubing, etc., and only include a puncture needle, dropper, flow control switch, infusion tubing, and outlet connector, existing nutrition connectors are more widely used, simpler in structure, and less expensive than existing nutrition delivery device structures. Therefore, the suction nozzle structure provided by this utility model can be used in conjunction with existing, more widely used nutrition connectors to achieve communication between infusion containers such as soft bags and nasogastric tubes, eliminating the need for a nutrition delivery device and effectively reducing operational complexity and usage costs. It should also be noted that the sealing film in the suction nozzle structure provided by this utility model can be opened. For nutrition connectors without a threaded cap at the head end but with a cup or bag fixed thereon, the sealing film can be directly removed, and the liquid in the container on one side of the tube can be poured into the cup or bag of the nutrition connector. This allows for direct delivery of liquid to the nasogastric tube using the cup-shaped or bag-shaped nutrition connector, without needing to connect the tube to the threaded cap at the head end of the nutrition connector.

[0020] Compared to existing technologies, the suction nozzle structure provided by this invention allows for connection between the container and the first end of the nutrition connector via a threaded tube on its outer wall. This enables the delivery of liquids such as nutrient solution from the container to the nasogastric tube connected to the end of the nutrition connector. Since the nutrition connector is simpler in structure than the nutrient delivery device, this suction nozzle structure, when used with the nutrition connector, effectively reduces the connection cost and operational complexity between the infusion container and the nasogastric tube. Furthermore, this suction nozzle structure can also be used with a sealing film to allow liquid to be poured out of the container, thus adapting to cup-type or bag-type nutrition connectors, effectively increasing the compatibility scenarios of this suction nozzle structure and greatly expanding the selectivity of clinical operations.

[0021] The bag assembly provided by this utility model includes the above-mentioned suction nozzle structure, and therefore the bag assembly has the same beneficial effects as the above-mentioned suction nozzle structure. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0031] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0032] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0033] Example:

[0034] like Figure 1 and Figure 2 As shown, the suction nozzle structure provided in this embodiment includes a mouth tube 1 and a sealing film 2; the outer wall of the mouth tube 1 is provided with an external thread, which is adapted to the internal thread of the inner wall of the threaded cap at the beginning of the external nutrition connector; one end of the mouth tube 1 is connected to the container opening of the external container, and the other end is fixed with a sealing film 2. The sealing film 2 is used to be punctured by a puncture needle inserted on the threaded cap when the mouth tube 1 is threadedly connected to the threaded cap, so that the puncture needle can be inserted into the container.

[0035] The suction nozzle structure provided in this embodiment can be used in clinical operations such as nasogastric feeding where nutrient solution or medication needs to be delivered. The mouth tube 1 in the suction nozzle structure can be fixed to the container opening of a container such as a soft bag by welding or integral molding. The container can be filled with liquid such as nutrient solution or medication. The sealing film 2 needs to be fixed to the end of the mouth tube 1 away from the container to seal the liquid inside the container.

[0036] When nasogastric feeding or other clinical procedures are required, existing nutrition connectors can be used to connect the container and the nasogastric tube. Specifically, the existing nutrition connector has a head end and a tail end, with the tail end connecting to the nasogastric tube and the head end equipped with a puncture needle. A threaded cap is fitted over and fixed to the puncture needle. Since the mouthpiece 1 in the suction nozzle structure provided in this embodiment has external threads on its outer wall and the sealing film 2 can be punctured by the puncture needle, when connecting the mouthpiece 1 to the nutrition connector, the puncture needle can first puncture through the sealing film 2 and then extend into the container such as a soft bag. Then, the threaded cap is threadedly connected to the mouthpiece 1. At this time, the threaded cap can be fixed to the outside of the mouthpiece 1 and can provide stable support for the puncture needle, so that the container and the nutrition connector are stably connected.

[0037] It should be noted that existing nutrition connectors, used to connect nutrition bags, feeding tubing, etc., and consisting only of a puncture needle, dropper, flow control switch, infusion tubing, and outlet connector, are more widely used, simpler in structure, and less expensive than existing nutrition delivery devices. Therefore, the suction nozzle structure provided in this embodiment can be used with the more widely used existing nutrition connectors to connect infusion containers such as soft bags to nasogastric tubes, eliminating the need for a nutrition delivery device and effectively reducing operational complexity and operating costs.

[0038] It should also be noted that the sealing film 2 is usually fixed to the mouth tube 1 of the suction tube by adhesive. Based on this, the sealing film 2 in the suction tube structure provided in this embodiment can also be opened. For nutrition connectors that do not have a threaded cap at the head end but have a cup or bag fixed thereon, the sealing film 2 can be opened directly and the liquid in the container on one side of the mouth tube 1 can be poured into the cup or bag of the nutrition connector. Thus, the liquid can be delivered to the nasogastric tube directly using the cup-shaped or bag-shaped nutrition connector, without having to connect the mouth tube 1 to the threaded cap at the head end of the nutrition connector.

[0039] Compared to existing technologies, the suction nozzle structure provided in this embodiment enables communication between the container and the first end of the nutrition connector via a threaded tube 1 on its outer wall. This allows liquids such as nutrient solution in the container to be delivered to the nasogastric tube connected to the end of the nutrition connector. Since the nutrition connector is simpler in structure than the nutrition delivery device, this suction nozzle structure can effectively reduce the communication cost and operational complexity between the infusion container and the nasogastric tube when used with the nutrition connector. Furthermore, this suction nozzle structure can also allow liquids in the container to be poured out via a sealing film 2, thus adapting to cup-type or bag-type nutrition connectors, effectively increasing the compatibility scenarios of this suction nozzle structure and greatly expanding the selectivity of clinical operations.

[0040] In this embodiment, the diameter of the mouth tube 1 is not limited. In order to make the suction nozzle structure provided in this embodiment compatible with the thread caps of common nutrition connectors and thus improve the compatibility of the suction nozzle structure, the diameter of the mouth tube 1 is preferably 8.6 mm.

[0041] like Figure 3 and Figure 4 As shown, the suction nozzle structure provided in this embodiment also includes a groove-shaped outer cover 3, which covers the mouth tube 1 and the sealing film 2.

[0042] The outer cover 3 can protect the sealing film 2 and the mouth tube 1, effectively preventing the sealing film 2 from being punctured by external objects.

[0043] To facilitate opening the outer cover 3 to expose the sealing film 2, and thus facilitate connecting the container and the nutrient connector, this embodiment preferably has a detachable connection between the outer cover 3 and the mouth tube 1.

[0044] The outer cover 3 and the inlet tube 1 can be detachably connected by a threaded connection or a pull ring.

[0045] like Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, an annular base 4 is fixedly connected to the end edge of the tube 1 away from the sealing film 2, and the outer cover 3 is snapped into the base 4.

[0046] The snap-fit ​​connection method can ensure the stability of the connection between the outer cover 3 and the tube 1, while effectively improving the ease of disassembly of the outer cover 3, thereby improving the operating experience of medical staff and patients.

[0047] The base 4 provides support for the outer cover 3, allowing the outer cover 3 to be stably attached to the outside of the inlet tube 1.

[0048] Furthermore, such as Figure 1 , Figure 2 and Figure 4 As shown, a retaining plate 30 extending along the axial direction of the outer cover 3 is provided at the edge of the groove of the outer cover 3, and a buckle 300 is provided on the side of the retaining plate 30 near the central axis of the outer cover 3; a limiting protrusion 40 is provided on the circumferential side wall of the base 4, and the retaining plate 30 can extend into one side of the limiting protrusion 40. The buckle 300 is used to move to the side of the limiting protrusion 40 away from the sealing film 2 when the outer cover 3 rotates, so that the buckle 300 and the limiting protrusion 40 abut against each other along the axial direction of the outer cover 3.

[0049] When the outer cover 3 needs to be installed outside the tube 1, the outer cover 3 can be placed over the tube 1 first, with the retaining plate 30 on the outer cover 3 extending into one side of the limiting protrusion 40 on the base 4. At this time, the retaining plate 30 and the limiting protrusion 40 are distributed sequentially along the circumference of the tube 1, forming a misalignment. The limiting protrusion 40 will not obstruct the process of placing the outer cover 3. Then, the outer cover 3 can be rotated to make the outer cover 3 rotate until the outer cover 3 drives the buckle 300 on the retaining plate 30 to rotate to the side of the limiting protrusion 40 away from the sealing film 2. At this time, the buckle 300 on the retaining plate 30 abuts against the bottom of the limiting protrusion 40, and can abut against the limiting protrusion 40 along the axial direction of the outer cover 3, effectively preventing the outer cover 3 from separating from the base 4.

[0050] Correspondingly, when it is necessary to remove the outer cover 3, the outer cover 3 can be rotated in the opposite direction until the locking plate 30 on the outer cover 3 rotates to be misaligned with the limiting protrusion 40 again. At this time, the buckle 300 on the locking plate 30 moves away from below the limiting protrusion 40 and no longer abuts against the limiting protrusion 40. The locking relationship between the outer cover 3 and the base 4 can be released, and the outer cover 3 can be removed from the base 4.

[0051] As can be seen, the suction nozzle structure provided in this embodiment can achieve mutual engagement between the outer cover 3 and the base 4 by rotating the outer cover 3 through the clamping plate 30 and the limiting protrusion 40. Compared with the engagement method by the buckle 300 and the interference fit of the slot, the suction nozzle structure provided in this embodiment can effectively prevent wear or cracking at the engagement point between the outer cover 3 and the base 4, which would lead to engagement failure.

[0052] like Figure 1 , Figure 5 and Figure 6 As shown, the outer cover 3 has a recessed portion 31 on its circumferential sidewall.

[0053] During use, the recessed part 31 can provide a support point for the operator to rotate the outer cover 3, thereby making it easier for the operator to rotate and open the outer cover 3, effectively improving the operating experience of the nozzle structure.

[0054] Furthermore, there are two recesses 31, which are symmetrically arranged on both sides of the outer cover 3.

[0055] The two recesses 31 symmetrically arranged on both sides of the outer cover 3 not only ensure the neatness of the appearance of the outer cover 3, but also make it easier for the operator to rotate the outer cover 3.

[0056] It should be noted that the location of the recess 31 on the side wall of the outer cover 3 is not limited, as long as it facilitates the operator's rotation of the outer cover 3. To prevent the location of the recess 31 from affecting the structural strength of the side wall of the outer cover 3 around the nozzle 1, such as... Figure 4 As shown, in this embodiment, the top of the outer cover 3 is preferably higher than the top of the inlet tube 1, as... Figure 1As shown, the recess 31 is provided on the circumferential side wall of the outer cover 3 above the top of the mouth tube 1. Specifically, the recess 31 is provided between the position of the outer cover 3 corresponding to the top of the mouth tube 1 and the top of the outer cover 3.

[0057] To facilitate holding the outer cover 3, the outer cover 3 can be designed as a prism.

[0058] In this embodiment, the container connected to one side of the nozzle tube 1 in the suction structure can be a plastic bottle, a soft bag, etc. To reduce space occupation, a soft bag is preferred in this embodiment. Based on the requirement for the soft bag to be laid flat during the water bath sterilization process, in order to prevent the outer cover 3 from being too thick and affecting the flat laying process of the soft bag, the outer cover 3 can be set as a quadrangular prism and the cross section of the outer cover 3 is rhomboid. At this time, the outer cover 3 has a flat structure and will not hinder the flat laying process of the soft bag.

[0059] like Figure 2 As shown, the sealing film 2 includes an adhesive part and a holding part. The adhesive part is fixed to the end opening of the tube 1, and the holding part is connected to one side of the adhesive part.

[0060] When the sealing film 2 includes an adhesive part and a holding part, the area of ​​the sealing film 2 can be larger than the end area of ​​the mouth tube 1. In this case, the part of the sealing film 2 that extends beyond the end of the mouth tube 1, i.e. the holding part, can provide support for the operator to peel off the sealing film 2, thereby effectively improving the ease of use of the nozzle structure.

[0061] The material of the sealing film 2 is not limited. Since the liquid medicine, nutrient solution and other liquids in the container need to undergo ultra-high temperature sterilization, in order to prevent the nozzle structure from being damaged by high temperature, the sealing film 2 is preferably made of a mixture of aluminum, polyester resin, nylon and chlorinated polypropylene.

[0062] When the sealing film 2 is made of a mixture of aluminum, polyester resin, nylon and chlorinated polypropylene, the sealing film 2 can be regarded as an aluminum-plastic film. In this case, the sealing film 2 can withstand a continuous sterilization process of up to 130°C for 30 minutes, which can effectively improve the adaptability of the nozzle structure to various sterilization processes, and will not leave insoluble particles at the mouthpiece 1 after the film is removed.

[0063] Furthermore, to prevent the mouthpiece 1 from being damaged by the high temperature during the ultra-high temperature sterilization process, in this embodiment, the mouthpiece 1 is preferably made of polypropylene. Correspondingly, when one end of the mouthpiece 1 is connected to the base 4, the base 4 is also preferably made of polypropylene.

[0064] Furthermore, such as Figure 1 and Figure 2 As shown, the side of the base 4 furthest from the nozzle 1 can also be connected to a hollow support 5, which is used to fix the container opening of a soft bag or similar container. For example, when the container is a soft bag, the support 5 can be fixed to the opening of the soft bag by a heat sealing process.

[0065] The mounting base can also be made of high-temperature resistant polypropylene.

[0066] This embodiment also provides a bag assembly, which includes the above-mentioned suction nozzle structure. Therefore, the bag assembly and the above-mentioned suction nozzle structure can solve the same technical problem and achieve the same technical effect, which will not be described in detail here.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
