Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a nose suction tube for children. Background Art

[0002] Neonatal departments currently use adult suction tubes to suction mucus in infants. When a child experiences nasal discharge, they remove an adult suction tube, shorten it, and connect it to negative pressure. If the discharge dries up, a syringe is used to draw out saline solution for humidification.

[0003] However, the above products have the following disadvantages:

[0004] 1. After the adult suction tube is shortened, there is only one suction hole and no side wall suction hole. The nasal mucus on the side is not easy to be sucked out. In addition, the cut end of the suction tube is not smooth and can easily damage the nasal mucosa of the newborn.

[0005] 2. Cannot directly moisten dry secretions;

[0006] 3. Adult suction devices cannot adjust the negative pressure well for fragile newborns. Utility Model Content

[0007] In view of the deficiencies in the prior art, the utility model provides a pediatric nasal suction tube, which solves the problems existing in the existing structure of nasal suction for newborns.

[0008] To achieve the above objectives, the present invention is implemented through the following technical solutions: a pediatric nasal suction tube, comprising:

[0009] The main straw serves as the main trunk to absorb the nasal mucus of young children;

[0010] The suction head is made of flexible material and is set at one end of the main suction tube. It is used to insert into the nasal cavity to suck out nasal mucus and has an anti-blocking design;

[0011] The injection tube is set on the side of the other end of the main suction tube and is used to inject normal saline to soften dry nasal mucus;

[0012] The negative pressure tube is placed on the other end of the main suction tube and is connected to a negative pressure device to suck out nasal mucus;

[0013] The pressure regulating tube is installed on one side of the negative pressure tube. The negative pressure of the negative pressure tube acting on the main suction pipe can be controlled by manually opening and closing the pressure regulating tube;

[0014] The anti-reflux structure is installed inside the negative pressure tube and located at the end face of the main suction tube. It prevents the mucus sucked into the negative pressure tube from flowing back into the main suction tube through one-way opening and closing.

[0015] Preferably, the end of the injection tube is covered with a rubber sleeve, and a through hole for inserting the syringe is opened in the center of the rubber sleeve.

[0016] Preferably, an anti-slip convex ring is provided on the side surface of the end portion of the liquid injection tube, and the rubber sleeve is deformably sleeved on the outside of the anti-slip convex ring to enhance the anti-slip effect.

[0017] Preferably, one end of the liquid injection tube located inside the main suction pipe is oblique, and the shackle faces the direction of the pressure regulating tube.

[0018] Preferably, the anti-backflow structure is a membrane flap that can completely cover the oblique end of the injection tube, and an arc-shaped edge is obliquely arranged on the inner side of the negative pressure tube between the anti-backflow structure and the pressure regulating tube, and when the negative pressure tube and the pressure regulating tube are tightly inserted, the arc-shaped edge presses one side of the anti-backflow structure against the oblique end surface of the injection tube.

[0019] Preferably, the main suction pipe, suction head, injection pipe, negative pressure pipe and pressure regulating pipe are all made of transparent plastic material.

[0021] Preferably, the suction head is provided with a concave structure on both opposite sides, and a long suction groove is opened in the middle of the concave structure. The concave structure prevents the long suction groove from directly contacting the nasal cavity to avoid negative pressure suction of the skin causing blockage of the long suction groove.

[0022] Preferably, a positioning structure for positioning the insertion angle of the main suction pipe is provided on one side of the connection end of the main suction pipe and the negative pressure pipe, so that the oblique opening of the injection pipe is parallel to the arc edge when the injection pipe is inserted into the negative pressure pipe;

[0023] Preferably, the positioning structure includes:

[0024] A positioning edge is provided on the side of one end of the main suction pipe close to the negative pressure pipe;

[0025] The positioning groove is provided on the side of the negative pressure tube and has a size adapted to the positioning edge.

[0029] 2. The suction head of this pediatric nasal suction tube adopts a large opening at the end combined with a long opening on the side, which can suction nasal mucus in multiple directions. At the same time, the design of the concave structure can reduce the chance of the suction long groove being blocked and avoid damage to the nasal mucosa caused by excessive suction.

[0030] 3. The positioning structure of the pediatric nasal suction tube can ensure that when the main suction tube is inserted into the negative pressure tube, the curved edge is kept parallel to the oblique opening of the injection tube to clamp the membrane flap, thereby ensuring a firm connection of the membrane flap.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] This utility model provides three technical solutions:

[0037] Figure 1-Figure 2 The first embodiment is shown: a pediatric nasal suction tube, comprising:

[0038] Main suction tube 1, serving as the main trunk to absorb children's nasal mucus;

[0039] The suction head 2 is made of flexible material and is provided at one end of the main suction tube 1. It is used to be inserted into the nasal cavity to suck out nasal mucus and has an anti-blocking design;

[0040] The injection tube 3 is provided on the side of the other end of the main suction tube 1 and is used to inject physiological saline to soften dry nasal mucus;

[0041] The negative pressure tube 4 is sleeved on the other end of the main suction tube 1 and is connected to a negative pressure device to suck out nasal mucus;

[0042] The pressure regulating tube 5 is provided on one side of the negative pressure tube 4. The negative pressure exerted by the negative pressure tube 4 on the main suction pipe 1 can be controlled by manually opening and closing the pressure regulating tube 5.

[0043] The anti-reflux structure 6 is arranged inside the negative pressure tube 4 and located at the end surface of the main suction tube 1. It prevents the mucus sucked into the negative pressure tube 4 from flowing back into the main suction tube 1 through one-way opening and closing.

[0044] In order to improve the sealing effect of the end of the injection tube 3, a rubber sleeve 31 is further provided on the end of the injection tube 3, and a through hole 32 for inserting the syringe is opened in the center of the rubber sleeve 31.

[0045] In order to prevent the rubber sleeve 31 from being pulled off when the syringe is pulled out, an anti-slip convex ring 33 is further provided on the side of the end of the injection tube 3, and the rubber sleeve 31 is deformed and sleeved on the outside of the anti-slip convex ring 33 to enhance the anti-slip effect.

[0046] One end of the liquid injection pipe 3 located inside the main suction pipe 1 is beveled, and the shackle faces the direction of the pressure regulating pipe 5;

[0047] The anti-backflow structure 6 is a membrane flap that can completely cover the oblique end of the injection tube 3. An arc-shaped ridge 41 is obliquely arranged on the inner side of the negative pressure tube 4 between the anti-backflow structure 6 and the pressure regulating tube 5. When the negative pressure tube 4 and the pressure regulating tube 5 are tightly inserted, the arc-shaped ridge 41 presses one side of the anti-backflow structure 6 against the oblique end surface of the injection tube 3.

[0048] In order to facilitate observation of the structure's suction of mucus and internal residues, the main suction tube 1, suction head 2, injection tube 3, negative pressure tube 4 and pressure regulating tube 5 are all made of transparent plastic material.

[0049] By providing a flexible suction head 2 at one end of the main suction tube 1, the comfort of inserting the suction tube into the nasal cavity of the child can be improved, and an injection tube 3 is provided at the other end for injecting normal saline, which can avoid the problem of dry nasal mucus being difficult to suck out. At the same time, a negative pressure tube 4 with a pressure regulating tube 5 is provided, and the suction pressure can be manually adjusted to avoid excessive suction causing harm to the child. The negative pressure tube 4 is designed to be separated from the main suction tube 1, so that the multi-section bifurcation is easy to disassemble and clean. At the same time, the internal membrane flap for preventing reflux can also be removed for cleaning or replacement, which is convenient to use.

[0050] Figure 3 A second embodiment is shown, which mainly differs from the first embodiment in that the suction head 2 is made of medical silicone and has an inwardly retracted opening at one end of the suction head 2 away from the main suction tube 1 .

[0051] The suction head 2 is provided with a concave structure 21 on both opposite sides, and a suction groove 22 is opened in the middle of the concave structure 21. The concave structure 21 prevents the suction groove 22 from directly contacting the nasal cavity to avoid negative pressure suction of the skin and causing blockage of the suction groove 22.

[0052] The suction head 2 adopts a combination of a large opening at the end and a long opening on the side, which can suck mucus in multiple directions. At the same time, the design of the concave structure 21 can reduce the chance of the suction long groove 22 being blocked and avoid damage to the nasal mucosa caused by excessive suction.

[0053] Figure 2 A third embodiment is also shown, which differs from the first embodiment mainly in that a positioning structure 8 for positioning the insertion angle of the main suction pipe 1 is further provided on one side of the connection end between the main suction pipe 1 and the negative pressure pipe 4;

[0054] Furthermore, the positioning structure 8 includes a positioning rib 81 provided on the side of the main suction pipe 1 and a positioning groove 82 opened on the side of the negative pressure tube 4. When the positioning rib 81 is inserted into the positioning groove 82, the arcuate rib 41 is parallel to the oblique end of the injection tube 3.

[0055] By providing the positioning structure 8, it can be ensured that when the main suction pipe 1 is inserted into the negative pressure tube 4, the arc-shaped edge 41 is kept parallel to the oblique opening of the injection tube 3 to clamp the membrane petal, thereby ensuring a firm connection of the membrane petal.

[0056] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0057] When in use, hold the main suction tube 1 and insert the suction tip 2 into the child's nasal cavity. If there is dry nasal mucus, insert the syringe into the rubber sleeve 31 and inject a small amount of normal saline. The normal saline flows into the nasal cavity through the main suction tube 1 and the suction tip 2 to moisten the nasal mucus.

[0058] When extracting nasal mucus, the external negative pressure device is used to extract the nasal mucus through the negative pressure tube 4-main suction tube 1-suction head 2. By covering or opening the pressure regulating tube 5 with your fingers, the amount of air inhaled by the pressure regulating tube 5 can be controlled, thereby controlling the negative pressure borne by the main suction tube 1.
