Description

Technical Field

[0001] The utility model relates to the technical field of medical devices and their peripheral supporting facilities, in particular to a children's nasal cavity negative pressure irrigation device. Background Technique

[0002] Nasal cavity negative pressure irrigation is a method of nasal cavity care. During operation, a nasal cavity aspirator needs to be connected to a disposable mushroom head type drainage tube, and then physiological saline is pressurized into the other nasal cavity by a syringe, and then the irrigation fluid in the nasal cavity is aspirated out under negative pressure by the disposable mushroom head type drainage tube, so as to achieve the effect of cleaning the nasal cavity.

[0003] During specific operation, first prepare 0.9% isotonic saline, which has less irritation to the nasal mucosa of children; then connect the disposable mushroom head drainage tube to the machine catheter and adjust the pressure value ≤ 0.02. Regarding the body position: Place a pillow under the child's shoulders to lower the head, drip physiological saline into both nostrils, and massage the middle of the nasal bridge and both sides of the nasal wings to make the saline fully enter the nasal cavity. After massage, turn on the negative pressure suction, press one nostril, and use the disposable mushroom head drainage tube to aspirate the other nostril. Generally, the disposable mushroom head drainage tube should leave the nostril and aspirate again after 1 - 2 seconds, otherwise it is easy to damage the nasal mucosa. During the aspiration process, children who are slightly older and more cooperative should say "open, open, open" to lift the soft palate to close the pharyngeal cavity. If the nose becomes dry during the process, saline should be dropped in time. After aspirating one side, aspirate the other side, or aspirate both sides alternately.

[0004] During operation, child patients often do not cooperate, and the disposable mushroom head drainage tube cannot be correctly inserted into the nasal cavity, and can only be tightly attached to the outside, unable to close well. The operation process takes a long time, and the pain during the operation causes child patients to struggle violently during nasal cavity negative pressure irrigation, resulting in skin damage to the compressed area. The mushroom head type disposable drainage tube is made of polyvinyl chloride material, which is relatively hard, easy to cause damage to the nasal skin, and cannot fit well with the nasal cavities of children of different ages, nor can it extend into the nasal cavity. The operator needs to use a syringe to inject physiological saline, and the operation difficulty is large. Content of the Utility Model

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] The purpose of the present utility model is to provide a children's nasal cavity negative pressure irrigation device to solve the problems existing in the above-mentioned prior art, and can effectively protect the skin of child patients during nasal cavity irrigation for children, improving the operation safety factor and the convenience of irrigation operation.

[0031] To make the above-mentioned objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0032] The utility model provides a children's nasal cavity negative pressure flushing device, which includes a drainage and filling tube 1 and a hand-held base 2. The drainage and filling tube 1 includes a soft head section 3, an operation section 5 and a connection section 6 that are connected in sequence. The soft head section 3 is made of silica gel material. The top of the soft head section 3 has a protrusion 4. One end opening of the drainage and filling tube 1 is located on the protrusion 4. The protrusion 4 can extend into the nasal cavity of a child. The soft head section 3 is connected to the connection section 6 by means of the operation section 5. The operation section 5 and the connection section 6 are made of polyvinyl chloride material. The connection section 6 has a conical structure. The larger diameter end of the connection section 6 is connected to the operation section 5. The other end opening of the drainage and filling tube 1 is located at the smaller diameter end of the conical structure of the connection section 6. And the connection section 6 can communicate with a filling device 7 and a drainage device. The hand-held base 2 is detachably connected to the drainage and filling tube 1. When the hand-held base 2 is connected to the drainage and filling tube 1, the hand-held base 2 is sleeved outside the operation section 5.

[0033] For the children's nasal cavity negative pressure flushing device of the utility model, the drainage and filling tube 1 can be connected to the filling device 7 and the drainage device. When the drainage and filling tube 1 is connected to the filling device 7, physiological saline can be filled into the nasal cavity of a child by using the drainage and filling tube 1. When the drainage and filling tube 1 is connected to the drainage device, the flushing liquid in the nasal cavity of a child can be sucked out by using the drainage and filling tube 1. The drainage and filling tube 1 includes a soft head section 3 made of silica gel material. The soft head section 3 has a protrusion 4 that can extend into the nasal cavity of a child. When filling physiological saline into the nasal cavity of a child and sucking out the flushing liquid from the nasal cavity of a child, the soft head section 3 and the protrusion 4 with a soft texture can provide effective protection for child patients, improving the safety of nasal cavity flushing operation. At the same time, the drainage and filling tube 1 is provided with an operation section 5 and a connection section 6. Both the operation section 5 and the connection section 6 are made of polyvinyl chloride material, enhancing the structural strength of the operation section 5 and the connection section 6, so that the drainage and filling tube 1 can meet the operation requirements. In addition, the operation section 5 can also be connected to the hand-held base 2. When the hand-held base 2 is connected to the drainage and filling tube 1, the hand-held base 2 is sleeved outside the operation section 5, further facilitating the operation of medical staff and improving the operation convenience of children's nasal cavity flushing.

[0034] Wherein, one side of the soft head section 3 facing the protrusion 4 is an arc surface that can fit the skin around the nostrils of a child, so that the protrusion 4 extends into the nasal cavity of a child. When the protrusion 4 extends into the nasal cavity of a child, the arc surface of the soft head section 3 can effectively protect the skin around the nostrils of a child. And the soft head 3 made of silica gel material has a certain elasticity and can deform to adapt to the facial shape around the nostrils of a child, effectively protecting the skin around the nostrils of child patients and improving the safety factor of the flushing operation.

[0035] In practical applications, the end face of the protrusion 4 can also be set as an arc surface to protect the mucous membrane in the nasal cavity of children. It should also be noted here that the height of the protrusion 4 can be determined according to the actual flushing requirements. In this specific embodiment, the height of the protrusion 4 is 0.5 cm. During actual flushing operations, it can be cut according to the requirements to make the diameter, height, radian, etc. of the protrusion 4 meet the usage requirements of different patients, further improving the flushing safety factor and at the same time enhancing the flexible adaptability of the device.

[0036] In other specific embodiments that can be achieved by the present utility model, the soft head section 3 is a hollow ellipsoidal structure, which better protects the skin around the nostrils of the patient and minimizes the discomfort of the patient during flushing as much as possible. The protrusion 4 is coaxially arranged with the soft head section 3. In practical applications, the shape and specifications of the soft head section 3 can be adjusted according to the actual operation requirements to meet different flushing needs.

[0037] In addition, it should also be noted that the operation section 5 can be set as a bent structure. Specifically, the operation section 5 includes a first branch section 501 and a second branch section 502. The first branch section 501 connects the soft head section 3 and the second branch section 502, and the second branch section 502 is connected to the connection section 6. There is an included angle between the first branch section 501 and the second branch section 502, so that when the protrusion 4 extends into the nasal cavity of a child, the filling device 7 is in a vertical state and its opening is downward. The bent operation section 5 enables the physiological saline in the filling device 7 to smoothly enter the nasal cavity of the child. When the operation section 5 is set as a bent structure, the size of the bend can be adjusted and determined according to the actual working conditions.

[0038] In this specific embodiment, the included angle between the first branch section 501 and the second branch section 502 is 120 degrees, so that the physiological saline in the filling device 7 can smoothly flow into the drainage filling tube 1. In practical applications, the angle between the first branch section 501 and the second branch section 502 can also be adjusted according to the actual flushing operation requirements.

[0039] More specifically, the connection section 6 extends into the filling device 7. The conical connection section 6 is convenient for inserting into the opening of the filling device 7 or connecting to the drainage device. And there are communication holes 8 on the side wall of the connection section 6 that extends into the filling device 7, ensuring that the connection section 6 can be connected to the filling device 7 and the drainage device. The filling device 7 is a bottled or stand-up bagged physiological saline, and the drainage device can be a mushroom head drainage tube or other drainage structures.

[0040] Furthermore, the handheld base 2 is of a ring structure. The handheld base 2 has a mounting hole 9 allowing the operation section 5 to pass through. The mounting hole 9 is a tapered hole, which facilitates the connection between the handheld base 2 and the operation section 5. Moreover, being a tapered hole, the mounting hole 9 enables the handheld base 2 to be connected to the drainage and filling tubes 1 of different specifications. When installing the handheld base 2, the connection section 6 of the drainage and filling tube 1 can be passed through the mounting hole 9 of the handheld base 2, and the handheld base 2 is moved until the mounting hole 9 abuts against a certain position of the operation section 5 and cannot be moved further, thereby realizing the clamping and fixing between the handheld base 2 and the operation section 5. It should be explained here that in actual applications, the operation section 5 can also be set to a tapered shape to achieve the transition connection between the soft head section 3 and the connection section 6. The specifications of the handheld base 2 can be determined according to actual operation requirements to further facilitate the flushing operation by medical staff.

[0041] To further improve the connection stability between the handheld base 2 and the operation section 5, the handheld base 2 has a mounting protrusion 10, and the operation section 5 has a mounting groove adapted to the mounting protrusion 10. The cooperation between the mounting protrusion 10 and the mounting groove can fix the relative positions of the drainage and filling tube 1 and the handheld base 2. When the handheld base 2 is installed in place, the mounting protrusion 10 cooperates with the mounting groove to fix the relative positions of the operation section 5 and the handheld base 2, thereby improving the connection stability between the drainage and filling tube 1 and the handheld base 2.

[0042] In actual applications, the number of the mounting protrusions 10 and the mounting grooves is multiple to adapt to the drainage and filling tubes 1 of different specifications. The mounting protrusion 10 can be set to an arc surface structure to avoid damaging the drainage and filling tube 1.

[0043] In other specific embodiments of the present utility model, the mounting protrusion 10 and the mounting groove are spiral, enabling the drainage and filling tube 1 and the handheld base 2 to achieve a connection similar to a threaded connection, further ensuring the connection stability between the drainage and filling tube 1 and the handheld base 2.

[0044] For the children's nasal cavity negative pressure flushing device of the present utility model, the soft head section 3 of the drainage and filling tube 1 is made of a silicone material. The soft head section 3 has a protrusion 4 that can extend into the nasal cavity of children. The protrusion 4 can be cut to adapt to different child patients. The soft head section 3 can also protect the skin around the nostrils of children. The handheld base 2 facilitates the operator to apply force and can ensure the cleanliness of the operator's hands. The operation section 5 can be set to a bent structure so that the connected physiological saline is above the nose. Moreover, the operation section 5 is made of polyvinyl chloride material and can be well inserted into the filling device 7 and the drainage device. The connection section 6 inserted into the filling device 7 and the drainage device has a communication hole 8 to ensure the normal flow of physiological saline and the flushing liquid.

[0045] In this utility model, specific examples are used to elaborate on the principles and implementation manners of the utility model. The description of the above embodiments is only used to help understand the method and its core idea of the utility model; at the same time, for those of ordinary skill in the art, according to the idea of the utility model, there will be changes in the specific implementation manners and application scopes. In summary, the content of this specification should not be construed as a limitation on the utility model.
