Description

Technical Field

[0001] This utility model belongs to the field of medical equipment technology, specifically an anesthesia mask suitable for infants and young children. Background Technology

[0002] Infants and young children often require anesthesia during medical procedures or certain special examinations to ensure the smooth progress of the surgery or examination. However, unlike adults, infants and young children are prone to fear and anxiety when faced with unfamiliar medical environments and equipment. This can cause them to cry and struggle during anesthesia, which not only greatly complicates the operation for medical staff and increases the difficulty and risk of anesthesia, such as potentially leading to unstable anesthesia mask placement or anesthetic gas leakage, but may also adversely affect the infant's vital signs, and may even delay the operation, endangering the infant's life.

[0003] Currently, existing infant anesthesia masks are often designed with only basic ventilation functions in mind, that is, delivering anesthetic gas to the infant's airway through the mask to achieve an anesthetic effect. Their structure typically includes a mask body, ventilation holes, and an air bag for sealing. However, existing infant anesthesia masks have many shortcomings in terms of soothing infants and meeting their physiological and psychological needs. There is an urgent need for a new type of infant anesthesia mask that can effectively solve these problems, thereby improving the safety, stability, and comfort of the anesthesia process for infants. Utility Model Content

[0004] To address the above problems, this utility model provides an anesthesia mask suitable for infants and young children. By designing a retractable nipple structure inside the mask, the anesthesia mask is more easily accepted by young children during anesthesia surgery, avoiding crying and struggling, and ensuring the smooth progress of the anesthesia surgery.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An anesthesia mask suitable for infants and young children includes a mask body with ventilation holes and an air bladder around the bottom edge of the mask body with a one-way valve. The mask body also has a retractable nipple assembly that is recessed into the mask cavity. The retractable nipple assembly includes a connecting tube connected to the inner wall of the mask body, with a retractable tube at one end of the connecting tube and a nipple at the other end of the retractable tube.

[0007] The beneficial effects of the above technical solution are as follows: by setting a retractable nipple component that is recessed into the cavity on the mask body, infants can suck on the nipple like a pacifier when using the anesthesia mask, thereby effectively soothing the infant's emotions, preventing the infant from crying and struggling, facilitating the smooth operation of anesthesia surgery by medical staff, and improving the stability and safety of the anesthesia process.

[0008] As a further improvement to the above solution, the telescopic nipple assembly is located below the vent hole.

[0009] The beneficial effects of the above technical solution are as follows: By placing the telescopic nipple assembly below the vent, this layout design allows the telescopic nipple assembly to be positioned precisely at the infant's mouth, making it easier for the infant to suck on the nipple. This further improves the infant's acceptance of the anesthesia mask and also makes it easier for medical staff to accurately adjust the relative position of the nipple and the infant's mouth, ensuring that the nipple can effectively soothe the infant.

[0010] As a further improvement to the above solution, the telescopic nipple assembly is provided with an inner tube component, one end of which is connected to the nipple head, and the other end extends out from inside the telescopic nipple assembly.

[0011] The beneficial effects of the above technical solution are as follows: Medical staff can directly control the position adjustment of the nipple through the inner tube component, thereby more accurately aligning it with the infant's mouth and achieving fine-tuning of the nipple position, improving adjustment flexibility. Furthermore, the inner tube component can be connected to a milk source through an external tube, forming a temporary feeding bottle for feeding. This allows for temporary feeding of the infant before anesthesia, further soothing the infant and, to some extent, preventing hypoglycemia caused by prolonged fasting, thus providing greater convenience and safety for anesthesia procedures.

[0012] As a further improvement to the above solution, the telescopic tube is a stepped variable diameter telescopic tube, which is composed of multiple tube segments with progressively larger diameters connected in sequence, and is made of silicone material.

[0013] The beneficial effects of the above technical solution are as follows: the stepped variable diameter telescopic tube design allows the telescopic tube to be adjusted to different lengths to meet the needs of different infants' facial contours and mouth positions. The silicone material has good flexibility and biocompatibility, and does not irritate the delicate skin and oral mucosa of infants. It ensures both the durability and operability of the telescopic tube, as well as the safety of infants. At the same time, the silicone telescopic tube also has a certain degree of elasticity, which can better fit the infant's face and improve the sealing and stability of the anesthesia mask.

[0014] As a further improvement to the above solution, the expandable tube is a corrugated tube structure.

[0015] The beneficial effects of the above technical solution are as follows: the retractable tube with the corrugated structure has good flexibility and bendability, and can stretch and deform to a certain extent with the movement of the infant's head or face when there are slight movements, thereby avoiding the nipple from detaching from the mouth or causing discomfort due to the infant's movements. At the same time, the corrugated structure also increases the strength and stability of the retractable tube, extends its service life, and further improves the overall performance of the anesthesia mask.

[0016] As a further improvement to the above solution, the nipple is not perforated.

[0017] The beneficial effects of the above technical solution are as follows: When the nipple is not perforated, it can be used as a pacifier to soothe infants and young children, making them feel comfortable and familiar when using the anesthesia mask, reducing crying and resistance. When feeding is required, the nipple can be connected to an external milk source, and milk can be delivered to the nipple through the inner tube. In this case, the nipple can be used as a bottle nipple to achieve the feeding function. This design not only increases the functionality of the anesthesia mask but also further improves the comfort and cooperation of infants and young children during the anesthesia process.

[0018] The overall beneficial effects of this invention compared to the prior art are as follows:

[0019] It effectively solves the problem of infants crying and struggling due to fear and discomfort during anesthesia, improving the smoothness and safety of anesthesia procedures. Its reasonable structural layout and various improvement schemes, such as the placement of the telescopic nipple component, the introduction of the inner tube component, the special structure and material selection of the telescopic tube, and the multi-functional design of the nipple head, not only enhance the comfort of infants and young children but also provide medical staff with greater operational convenience and safety, demonstrating high practical value and promising prospects for widespread application.

[0025] To enable those skilled in the art to better understand the technical solution, the present invention will be described in detail below with reference to the embodiments. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0026] Example 1

[0027] This utility model provides an anesthesia mask suitable for infants and young children. Its main structure includes a mask body 2, a vent 3, an air bladder 1, a one-way valve 5, and a retractable nipple assembly 4. The mask body 2, as the basic component of the entire mask, is designed in shape and size according to the facial features of infants and young children to ensure a close fit without causing pressure or discomfort. The mask body 2 is provided with a vent 3 for connecting to an anesthetic gas delivery pipe, allowing the anesthetic gas to smoothly enter the mask cavity.

[0028] An air bladder 1 is provided around the bottom edge of the mask 2. The air bladder 1 can be inflated or deflated via a one-way valve 5. When anesthesia masks are needed, medical staff can adjust the amount of gas in the air bladder 1 according to the differences in the infant's facial contours, causing the air bladder 1 to expand or contract. This ensures a good seal between the anesthesia mask and the infant's face, preventing leakage of anesthetic gas and avoiding excessive pressure on the infant's face, thus ensuring the infant's comfort.

[0029] The telescopic nipple assembly 4, which is recessed into the cavity of the cover body 2, is one of the key innovations of this utility model. Its specific structure includes a connecting tube 43 connected to the inner wall of the cover body 2, a telescopic tube 42 located at the end of the connecting tube 43, and a nipple head 41 located at the end of the telescopic tube 42. Among them, the connecting tube 43 plays a role in fixing and supporting, connecting the telescopic nipple assembly 4 as a whole to the cover body 2, and ensuring its communication with the internal space of the cover body 2.

[0030] The telescopic tube 42 features a special structural design, allowing for the selection of either a stepped variable-diameter telescopic tube or a corrugated tube structure depending on actual needs. Taking the stepped variable-diameter telescopic tube as an example, it consists of multiple tube segments with progressively increasing diameters connected sequentially. This design enables the telescopic tube 42 to freely extend and retract within a certain range, allowing medical personnel to flexibly adjust the distance between the nipple 41 and the infant's mouth according to different mouth positions and needs, thus better soothing the infant and improving the fit and effectiveness of the anesthesia mask. The corrugated tube 42, on the other hand, possesses excellent flexibility and bendability. When the infant's head or face makes slight movements, the telescopic tube 42 can extend and deform accordingly, preventing the nipple 41 from detaching from the infant's mouth or causing discomfort, further improving stability and comfort during use.

[0031] The nipple head 41 is located at the end of the retractable tube 42. Its shape and material simulate a real nipple, and it is made of soft and non-toxic materials, such as food-grade silicone, to ensure that it does not irritate or harm the infant's oral mucosa and can provide the infant with a tactile sensation and experience similar to that of real breastfeeding. In this embodiment, the nipple head 41 is not perforated and is mainly used as a pacifier. When the infant uses the anesthesia mask, he / she can suck on the nipple head 41 like a regular pacifier, thereby effectively relieving the infant's tension and crying and struggling behavior, making the infant more cooperative during the anesthesia procedure, and providing medical staff with a relatively stable and quiet surgical environment.

[0032] Example 2

[0033] Based on Embodiment 1, this embodiment optimizes the position of the telescopic nipple assembly 4 by placing it below the vent 3. This arrangement allows the telescopic nipple assembly 4 to be more precisely aligned with the infant's mouth area. Since the vent 3 is generally located at the upper part of the cover 2, and the infant's mouth is usually at a relatively low position on their face, placing the telescopic nipple assembly 4 below the vent 3 better conforms to the natural distribution of the infant's facial structure. This allows the nipple head 41 to naturally reach the infant's mouth, further improving the infant's acceptance and comfort with the nipple head 41. It also facilitates observation and adjustment by medical personnel, ensuring that the nipple head 41 can correctly play its soothing role.

[0034] Example 3

[0035] This embodiment further improves the structure of the telescopic nipple assembly 4 based on embodiment 1 by adding an inner tube component 44. One end of the inner tube component 44 is connected to the nipple head 41, and the other end extends out from the telescopic nipple assembly 4. By setting the inner tube component 44, medical personnel can directly control it to achieve precise adjustment of the nipple head 41 position. This allows for more flexible adjustment of the extension or retraction degree of the nipple head 41 in real time according to the different reactions and needs of infants, ensuring that the nipple head 41 is always in the optimal position in the infant's mouth, thus improving the reliability of the soothing effect.

[0036] Furthermore, the inner tube component 44 also functions to connect to an external milk source. By connecting the other end of the inner tube component 44 to an external bottle or other milk delivery device, the nipple 41 can also function as a feeding device. Before anesthesia, if the infant is hungry or needs further comforting, medical staff can use the inner tube component 44 to deliver milk to the nipple 41, allowing the infant to suckle like with a regular bottle. This not only more effectively soothes the infant, keeping them calm and cooperative, but also helps prevent discomfort such as hypoglycemia that may occur due to prolonged fasting, providing a more comprehensive guarantee for the smooth progress of anesthesia.

[0037] Example 4

[0038] In this embodiment, the telescopic tube 42 adopts a stepped variable diameter telescopic tube structure made of silicone. Silicone material has excellent flexibility, biocompatibility, and durability, and will not cause adverse irritation to the skin and oral mucosa of infants. Its flexibility ensures that the telescopic tube 42 will not easily break or be damaged during extension and retraction, ensuring safety and reliability. The stepped variable diameter telescopic tube is composed of multiple tube segments with progressively increasing diameters connected sequentially. This design provides better stability and support for the telescopic tube 42 during extension and retraction. The connection points between each tube segment effectively distribute stress, preventing excessive bending or deformation, thereby extending the service life of the telescopic tube 42. Furthermore, the stepped variable diameter structure can provide a more precise range of extension and retraction adjustment according to the different facial features and mouth positions of infants, making the nipple 41 more closely fit the actual needs of infants and improving their comfort and user experience.

[0039] Example 5

[0040] Unlike Example 4, the retractable tube 42 in this example adopts a corrugated tube structure. The corrugated tube structure gives the retractable tube 42 greater flexibility and bendability, allowing it to better adapt to minor head movements or facial expressions that may occur during anesthesia. When the infant's head or face makes slight movements, the retractable tube 42 with the corrugated structure can correspondingly extend, retract, and bend, thereby maintaining good contact between the nipple 41 and the infant's mouth, avoiding problems such as emotional fluctuations in the infant or damage to the anesthesia mask's seal caused by the nipple 41 detaching from the infant's mouth. Simultaneously, the corrugated tube structure also has a certain degree of elasticity and recovery ability, quickly returning to its original shape after being subjected to external force, further enhancing the stability and reliability of the retractable tube 42 and ensuring that the performance of the anesthesia mask remains unaffected throughout its use.

[0041] Example 6

[0042] In this embodiment, the nipple 41 is not perforated and its main function is as a pacifier. In this case, the shape and material design of the nipple 41 are crucial, needing to simulate the feel and appearance of a real pacifier or mother's nipple as closely as possible, so that infants can more easily accept and develop a sense of dependence. When using an anesthesia mask, the infant sucks on the unperforated nipple 41, and the sucking action and tactile stimulation of the nipple 41 on the mouth effectively relieves their tension and discomfort, reduces crying and struggling, and creates favorable surgical conditions for medical staff.

[0043] Working principle and operating procedures

[0044] 1. Working principle

[0045] Sealing and anesthetic gas delivery principle: When the anesthetic mask is used, the mask body 2 covers the infant's face. By adjusting the amount of gas in the airbag 1, the airbag 1 is made to fit tightly against the infant's face, forming a relatively closed mask cavity. The vent 3 is connected to the anesthetic gas delivery pipeline. The anesthetic gas enters the mask cavity through the vent 3. The infant inhales the anesthetic gas in the mask cavity through respiration, thereby achieving the anesthetic effect.

[0046] Soothing principle: The nipple head 41 in the telescopic nipple assembly 4 is located near the infant's mouth. When the infant uses the anesthesia mask, he / she will instinctively suck on the nipple head 41, just like sucking on a pacifier or the mother's nipple. Through the sucking action and the tactile stimulation of the mouth by the nipple head 41, the infant's nervous system can be effectively soothed, making his / her emotions calm down, reducing crying and struggling behavior, thereby improving the infant's acceptance and cooperation with the anesthesia mask.

[0047] Feeding principle: When the nipple 41 is connected to an external milk source (via the inner tube component 44), milk flows into the nipple 41 through the inner tube component 44, allowing the infant to feed by sucking on the nipple 41. This principle is the same as that of ordinary bottle feeding, but it incorporates the function of an anesthesia mask, enabling temporary feeding of the infant before anesthesia to meet their physiological needs and further enhance the soothing effect.

[0048] 2. Operating Procedures

[0049] Preparation

[0050] Select an anesthesia mask of appropriate size and model according to the infant's age, body shape and facial features, and check whether each part of the mask is intact, such as whether the mask body 2 has cracks, whether the vent 3 is unobstructed, whether the air bag 1 is leaking, whether the one-way valve 5 is working properly, and whether the telescopic nipple assembly 4 moves freely, etc.

[0051] The anesthesia masks undergo strict disinfection to ensure they meet medical sterility requirements and avoid the risk of infection to infants and young children.

[0052] Connect the ventilation port 3 of the anesthesia mask to the gas delivery pipeline of the anesthesia machine, and check the sealing of the connection to ensure that the anesthetic gas can be delivered stably and safely into the mask cavity.

[0053] If feeding is required during anesthesia, an external milk source (such as a bottle or milk storage bag) must be prepared, and the quality and hygiene of the milk source must be ensured to meet the standards. At the same time, the milk source should be connected to the inner tube component 44 of the telescopic nipple assembly 4, and the connection should be checked to ensure that the milk can be smoothly delivered to the nipple 41 through the inner tube component 44.

[0054] Wearing anesthesia mask

[0055] The procedure is performed by two medical staff. One staff member gently holds the infant's head to keep it relatively stable, while the other staff member holds an anesthesia mask and gently covers the infant's face with the mask, ensuring that the mask is in full contact with the infant's face, but without applying too much pressure to the infant's face to avoid causing discomfort.

[0056] Telescopic nipple assembly 4: adjustment and soothing operation

[0057] Based on the infant's mouth position and needs, medical staff manually adjust the retractable tube 42 of the telescopic nipple assembly 4 through the inner tube component 44 to move the nipple head 41 to a suitable position near the infant's mouth, thus inducing the infant to latch onto the nipple head 41. During the adjustment process, the movements should be gentle and slow to avoid startling or stimulating the infant.

[0058] If the infant can successfully latch onto the nipple 41, further observe their emotional changes. Adjust the position and angle of the nipple 41 appropriately based on the infant's reaction to ensure comfortable sucking and achieve the best soothing effect. If the infant has low acceptance of the nipple 41, try gently shaking the nipple 41 or adjusting the overall position of the mask to guide the infant to gradually adapt to the presence of the nipple 41.

[0059] In summary, this utility model of anesthesia mask for infants and young children, through its ingenious structural design and integration of multiple functions, effectively solves the problem of infants and young children crying and struggling due to fear and discomfort during anesthesia, while meeting their ventilation needs. It improves the success and safety of anesthesia surgery and has significant clinical application value and promotion prospects.
