Description

Technical Field

[0001] This utility model relates to the field of medical support devices for use on the body, and in particular to a hose fixing headgear for use with a ventilator. Background Technology

[0002] A ventilator is a device that can alter, control, or replace normal physiological breathing, improve respiratory function, increase lung ventilation, reduce respiratory work consumption, and conserve cardiac energy reserves. It is currently one of the essential pieces of equipment for neonatal intensive care.

[0003] The air supply method of the pediatric ventilator is achieved through an air delivery tube connected to the ventilator. When in use, the middle of the air delivery tube is horizontally positioned between the upper lip and the outer end of the nostril of the child. The air delivery tube has a corresponding connecting tube at the nostril. The connecting tube is used to fit into the patient's nostril. The air provided by the ventilator enters the nostril of the child through the air delivery tube and the connecting tube for the child to inhale. Conventional air delivery tubes lack any structural support to conform to the skin of young patients. Clinical staff typically attach the air delivery tube to the patient's skin using medical tape. However, young patients are naturally curious and active, making the air delivery tube, which is placed in front of them without any support or fixation, easily displaced. This can cause the secondary tube to fail to effectively align with the nostrils, affecting the delivery of air. To address this, Chinese utility model patent CN202323374122.0 proposes a ventilator air delivery tube fixing cap for children. This solution uses fixing sections on both sides of the cap to limit the air delivery tube, preventing it from being directly in front of the young patient's field of vision and reducing its distraction. In practical use, it was found that although this technology can locate the air delivery tube at the top of the child's head, the air delivery tube between the two fixed parts lacks support. The conventional air delivery tube is a rubber hose, and the unsupported rubber hose is prone to making intermittent rubbing contact with the child's cheeks. This unstable contact can easily cause discomfort to the child's face, making the child want to scratch. Utility Model Content

[0004] In view of at least one of the above-mentioned technical problems, this utility model provides a head cover for fixing the air delivery tube of a ventilator for young children. By setting an open clamp sleeve at the glass bend of the air delivery tube, a support portion is provided at the lower part of the air delivery tube. This support portion cooperates with the tube body fixing unit on the ring sleeve to form a support structure for the air delivery tube on the face of the young patient, effectively reducing the tendency of the air delivery tube to move laterally in front of the young patient due to the lack of fixed support. The specific technical solution is as follows: A headband for securing the air delivery tube of a ventilator for young children includes a ring and an air delivery tube. The ring is made of nursing elastic band, and the front side of the ring has tube-body securing units on both sides. The air delivery tube includes a cylindrical nasal oxygen tube with openings at both ends. Two parallel nasal plug tubes are connected through the middle of the nasal oxygen tube. A glass bend is fitted inside each opening at both ends of the nasal oxygen tube. An air delivery soft rubber branch tube is fitted outside the upper end of the glass bend tube. The two air delivery soft rubber branch tubes are connected to the main air delivery soft rubber tube after being fitted through the tube-body securing units. The outer end of the main air delivery soft rubber tube is used to connect to the ventilator. An open clamp sleeve is fitted on the outer wall of the glass bend tube. The open clamp sleeve is made of soft material and has a contact concave surface on its inner side.

[0005] In some embodiments of this disclosure, the loop is a ring structure in which the end of the elastic band is attached and the sides are sewn together.

[0006] In some embodiments of this disclosure, the ring sleeve is provided with several ventilation holes.

[0007] In some embodiments of this disclosure, the array of vent holes is distributed on the main body of the ring.

[0008] In some embodiments of this disclosure, the side of the tube ring-fixing unit is provided with a closable channel; when the channel is closed, the tube ring-fixing unit is a closed ring structure; when the channel is open, the air supply soft rubber branch pipe enters or leaves the ring-fixing area of ​​the tube ring-fixing unit through the channel.

[0009] In some embodiments of this disclosure, the tube ring-fixing unit is a soft rope, with the middle of the soft rope fixed to the side of the front side of the ring; when the two ends of the soft rope are knotted, the channel is closed, and the inner wall of the soft rope wraps around and abuts the outer wall of the air delivery soft rubber branch pipe to form a ring fixation; when the two ends of the soft rope are not knotted, the channel is open.

[0010] In some embodiments of this disclosure, the tube ring-fixing unit is a flexible sheet body. The middle part of the flexible sheet body is fixed to the side of the front side of the ring sleeve. The two ends of the flexible sheet body are respectively provided with hook and loop fasteners. When the hook and loop fasteners are attached together, the channel is closed, and the inner wall of the soft rope wraps around and adheres to the outer wall of the air delivery soft rubber branch tube to form a ring fixation. When the two ends of the soft rope are not knotted, the channel is open.

[0011] In some embodiments of this disclosure, the tube ring-fixing unit is a flexible sheet body. The middle part of the flexible sheet body is fixed to the side of the front side of the ring sleeve. The two ends of the flexible sheet body are respectively provided with a male buckle and a female buckle. When the male buckle and the female buckle are fastened together, the channel is closed, and the inner wall of the flexible sheet body hugs and abuts the outer wall of the air delivery soft rubber branch tube to form a ring fixation. When the two ends of the flexible sheet body are not fastened together, the channel is open.

[0012] In some embodiments of this disclosure, the base of the nasal plug tube is provided with a nasal membrane.

[0013] In some embodiments of this disclosure, the open clamp sleeve is a fracture ring body, the fracture is a fan-shaped fracture with a large diameter on the outside, and the width of the inner end of the fracture is smaller than the inner ring diameter of the fracture ring body.

[0014] Compared with existing technologies, the above-mentioned head cover for fixing the air delivery tube of a ventilator for young children has the following beneficial effects: By installing an open clamp sleeve at the glass bend of the air delivery tube, a support section is also provided at the bottom of the air delivery tube. This support section cooperates with the tube body fixing unit on the ring sleeve to form a support structure for the air delivery tube on the face of the young patient. This effectively reduces the ability of the air delivery tube to move laterally in front of the young patient due to the lack of fixed support. It also reduces the contact between the soft rubber tube of the air delivery tube and the face when the young patient adjusts the angle of their head, thereby reducing the motivation for the young patient to actively manipulate the air delivery tube.

[0015] The loops of the nursing elastic band make it easy to put on, reducing the difficulty of putting it on due to the low cooperation of young patients.

[0016] The open clamp sleeve made of soft material can effectively prevent scratches on the face of young patients, and has a high safety factor.

[0017] The concave design allows it to fit the natural curves of the skin on a young patient's face, reducing the displacement of the opening clamp sleeve. Attached Figure Description

[0019] To better understand the purpose, structure, and function of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below. It should be noted that, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing specific embodiments only and is not intended to limit this application. The terms "comprising" and "equipped with," and any variations thereof, are open-ended and intended to cover non-exclusive inclusion. In the description of this application, it should be understood that the directional terms "upper," "lower," "inner," and "outer," etc., indicate directional or positional relationships based on the appendix. Figure 1 The orientations or positional relationships shown are for ease of description only and are not intended to indicate or imply that the device or unit referred to must have a specific orientation, be constructed or operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0020] As shown in the attached diagram. Figures 1 to 3 As shown, a headband for securing the air delivery tube of a ventilator for young children is designed, comprising a ring 1 and an air delivery tube 2. The ring 1 is made of nursing elastic band, which can match different head circumferences of young patients. The nursing elastic band ring 1 is easy to wear, reducing the difficulty of wearing due to low cooperation from young patients. Tube securing units 11 are provided on both sides of the front side of the ring 1. The air delivery tube 2 includes a cylindrical nasal oxygen tubing 21 with openings at both ends. The nasal oxygen tubing 21 is made of soft rubber. Two parallel nasal plug tubing 211 are connected through the middle of the nasal oxygen tubing 21. A glass bend 22 is fitted inside each opening at both ends of the nasal oxygen tubing 21. The nasal oxygen tubing 21 is a medical soft rubber tubing, and the glass bend 22 passes through the end of the nasal oxygen tubing 21. Inside the mouth, the sleeve length is not less than 1 cm, and a stable connection is formed by the contraction force of the nasal oxygen tubing 21 itself. The upper end of the glass bend tube 22 is sleeved with an air delivery soft rubber branch tube 23. The two air delivery soft rubber branch tubes 23 are connected to the air delivery soft rubber main tube after being sleeved through the tube body ring fixing unit 11. The outer end of the air delivery soft rubber main tube is used to connect to the ventilator. The outer wall of the glass bend tube 22 is equipped with an opening clamp sleeve 3. The opening clamp sleeve 3 is made of soft material. The inner side of the opening clamp sleeve 3 is provided with a contact concave surface 31. The soft material of the opening clamp sleeve 3 can effectively avoid scratching the face of the child patient, with a high safety factor. The setting of the contact concave surface 31 can be curved to fit the natural arc protrusion of the skin of the child patient's face, reducing the sliding displacement of the opening clamp sleeve 3.

[0021] The head circumference of children aged 1 to 6 years is usually between 43 and 54 cm. Before fitting the rings to young patients, clinicians can select different sizes of rings according to the size of the patient's head circumference, so as not to obstruct the patient's vision and not to fall off on their own.

[0022] In use, clinical personnel secure the air delivery soft rubber branch tube 23 inside the tube body fixing unit 11. Because the ring 1 is made of soft material, after the tube body fixing unit 11 and the air delivery soft rubber branch tube 23 are in circular contact, the outer end will naturally droop under the action of gravity, thereby generating friction with the outer wall of the air delivery soft rubber branch tube 23, which can effectively prevent the air delivery soft rubber branch tube 23 from falling down on its own. It should be noted that the tube body fixing unit 11 only needs to be in circular contact with the air delivery soft rubber branch tube 23, and it is not necessary to tighten or bind it, so as to avoid affecting the inner diameter of the air delivery soft rubber branch tube 23.

[0023] The open clamp sleeve 3 is clamped onto the outer wall of the glass bend 22 from the break point. The inner wall of the open clamp sleeve 3 is fully pressed against the outer wall of the glass bend 22, so that it cannot slide on its own without external force.

[0024] Next, place the ring 1 on the upper side of the child's head, above the child's eyes, ensuring it does not obstruct the child's vision and is not easily dislodged. Insert the two nasal plug tubes 211 into one of the child's nostrils, so that the contact concave surface 31 contacts the child's cheek. Because the open clamp sleeve 3 itself has a certain diameter, the open clamp sleeve 3 connected to the outer wall of the glass bend tube 22 will contact the child's cheek first.

[0025] Two air-supply soft rubber branch tubes 23 are connected to the main air-supply soft rubber tube at the back of the infant patient's head, and the outer end of the main air-supply soft rubber tube is connected to the ventilator.

[0026] It should be noted that the tubing used in this technical solution is all odorless, transparent, medical-grade PVC tubing.

[0027] Through the above-described usage, the air delivery tube 2 has five supporting connection points on the face of the young patient: two left and right tube ring fixing units 11, two left and right open clamp sleeves 3, and the middle lower nasal plug tube 211. These provide relatively stable support on the face of the young patient, effectively reducing the ability of the air delivery tube 2 to move laterally in front of the young patient due to the lack of fixed support. This also reduces the contact between the soft tube of the air delivery tube 2 and the face when the young patient adjusts the angle of their head, thereby reducing the motivation for the young patient to actively manipulate the air delivery tube 2.

[0028] The above embodiments illustrate three examples of implementing the aforementioned technical solutions. The term "embodiment" as used herein means that a specific feature, structure, or characteristic described in connection with an embodiment can be included in at least one embodiment of this application. The appearance of this phrase in various locations within the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. Where there is no conflict, the various embodiments in this application can be combined with each other.

[0029] Example 1 discloses a head cover for fixing the air delivery tube of a ventilator for young children, including a ring 1 and an air delivery tube 2. The ring 1 is made of elastic fiber knitted nursing elastic band. The ring 1 is a ring structure with the end of the nursing elastic band close to the side and sewn together. Different sizes are selected according to the different head circumference ranges of young patients. The ring 1 is typically 35-60cm in length, with a different size every 5cm. The elastic band material of the ring 1 makes it easy to wear, allowing it to be directly placed over the head of young patients, reducing the difficulty of wearing it due to their low cooperation. The front side of the ring 1 has two opposing tube-shaped fixing units 11. The air delivery tube 2 includes a cylindrical nasal oxygen tubing 21 with openings at both ends. The nasal oxygen tubing 21 is made of soft rubber. Two parallel nasal plug tubing 211 are connected through the middle of the nasal oxygen tubing 21. A glass bend 22 is fitted inside each opening of the nasal oxygen tubing 21. The nasal oxygen tubing 21 is a medical soft rubber tubing, and the glass bend 22 passes through the port of the nasal oxygen tubing 21 with a fitting length of not less than 1 cm. The nasal oxygen tubing 21 forms a stable connection through the elastic contraction force of its own gel material. The upper end of the glass bend 22 is fitted with an air delivery soft rubber branch tube 23. The two air delivery soft rubber branch tubes 23 are connected to the air delivery soft rubber main tube after being sleeved through the tube body ring fixing unit 11. The outer end of the air delivery soft rubber main tube is used to connect to the ventilator. The outer wall of the glass bend 22 is equipped with an open clamp sleeve 3. The open clamp sleeve 3 is made of soft material. The inner side of the open clamp sleeve 3 is provided with a contact concave surface 31. The soft material of the open clamp sleeve 3 can effectively avoid scratching the face of the child patient, with a high safety factor. The setting of the contact concave surface 31 can be curved to fit the natural arc protrusion of the skin of the child patient's face, reducing the sliding displacement of the open clamp sleeve 3.

[0030] The ring 1 includes several ventilation holes 12. These ventilation holes not only increase breathability but also reduce weight to some extent, optimizing wearing comfort. The tube-body ring-fixing unit 11 has a closable channel on its side. When the channel is closed, the tube-body ring-fixing unit 11 is a closed loop structure. When the channel is open, the air-supplying soft rubber branch tube 23 enters or leaves the ring-fixing area of ​​the tube-body ring-fixing unit 11 through the channel. In this embodiment, the tube-body ring-fixing unit 11 is a soft rope. The middle part is fixedly connected to the side of the front side of the ring sleeve 1 by stitching; when the two ends of the soft rope are knotted, the channel is closed, and the inner wall of the soft rope wraps around and abuts the outer wall of the air supply soft rubber branch pipe 23 to form a ring fixation; when the two ends of the soft rope are not knotted, the channel is open, and the air supply soft rubber branch pipe 23 can be separated from the contact of the pipe body ring fixation unit 11; the overall structure of the open clamp sleeve 3 is a broken ring body, the break is a fan-shaped break with a large diameter on the outside, and the width of the inner end of the break is smaller than the inner ring diameter of the broken ring body, which facilitates installation and disassembly. The material of the open clamp sleeve 3 can be at least one of medical sponge, medical silicone sponge, and medical polyester padding.

[0031] Before administering the ring to young patients, clinicians can select different sizes of rings based on the size of the patient's head circumference, ensuring that the rings do not obstruct the patient's vision and are not easily dislodged.

[0032] In use, clinical personnel secure the air delivery soft rubber branch tube 23 inside the tube body securing unit 11. Because the ring 1 is made of soft material, after the tube body securing unit 11 and the air delivery soft rubber branch tube 23 are in circular contact, the outer end will naturally droop under the action of gravity, thus generating friction with the outer wall of the air delivery soft rubber branch tube 23, effectively preventing the air delivery soft rubber branch tube 23 from falling due to its own weight. It should be noted that the tube body securing unit 11 only needs to be in circular contact with the air delivery soft rubber branch tube 23; it does not need to be tightened or bound, so as to avoid affecting the inner diameter of the air delivery soft rubber branch tube 23 and thus interfering with the ventilation effect.

[0033] The open clamp sleeve 3 is clamped onto the outer wall of the glass bend 22 from the break point. The inner wall of the open clamp sleeve 3 is fully pressed against the outer wall of the glass bend 22, so that it cannot slide on its own without external force.

[0034] Next, place the ring 1 on the upper side of the child's head, above the child's eyes, ensuring it does not obstruct the child's vision and is not easily dislodged. Insert the two nasal plug tubes 211 into one of the child's nostrils, so that the contact concave surface 31 contacts the child's cheek. Because the open clamp sleeve 3 itself has a certain diameter, the open clamp sleeve 3 connected to the outer wall of the glass bend tube 22 will contact the child's cheek first.

[0035] Two air-supply soft rubber branch tubes 23 are connected to the main air-supply soft rubber tube at the back of the infant patient's head, and the outer end of the main air-supply soft rubber tube is connected to the ventilator.

[0036] Through the above-described usage, the air delivery tube 2 has five supporting connection points on the face of the young patient: two left and right tube ring fixing units 11, two left and right open clamp sleeves 3, and the middle lower nasal plug tube 211. These provide relatively stable support on the face of the young patient, effectively reducing the ability of the air delivery tube 2 to move laterally in front of the young patient due to the lack of fixed support. This also reduces the contact between the soft tube of the air delivery tube 2 and the face when the young patient adjusts the angle of their head, thereby reducing the motivation for the young patient to actively manipulate the air delivery tube 2.

[0037] Example 2 discloses a head cover for fixing the air delivery tube of a ventilator for young children. The difference between this example and Example 1 is that the ring 1 is a woven elastic band made of elastic fabric. The ring 1 is usually in the range of 33-60cm, with a different size every 3cm. The ventilation holes 12 are channels designed during weaving, and several ventilation holes 12 are distributed in a ring array on the main body of the ring 1. The tube ring fixing unit (11) is a soft sheet. The middle part of the soft sheet is bonded to the side of the front side of the ring 1. The two ends of the soft sheet are respectively provided with a male buckle and a female buckle. When the male buckle and the female buckle are fastened together, the channel is closed, and the inner wall of the soft sheet hugs and abuts the outer wall of the air delivery soft rubber branch tube 23 to form a ring fixation. When the two ends of the soft sheet are not fastened, the channel is open.

[0038] like Figures 1 to 3 As shown, Embodiment 3 discloses a headband for fixing the air delivery tube of a ventilator for young children. The difference between this embodiment and Embodiment 2 is that the elastic fiber woven medical elastic band of the ring 1 is typically in the range of 35-60cm, with a different size every 5cm; several ventilation holes 12 are vertically arranged in a multi-level annular array on the main body of the ring 1; the tube ring fixing unit 11 is a soft sheet, the middle of which is fixed to the side of the front side of the ring 1, and the two ends of the soft sheet are respectively provided with hook and loop fasteners; when the hook and loop fasteners are attached together, the channel is closed, and the inner wall of the soft rope wraps around and adheres to the outer wall of the air delivery soft rubber branch tube 23 to form a ring fixation; when the two ends of the soft rope are not knotted, the channel is open. In this embodiment, the nasal plug tube (211) is provided with a nasal membrane 212 at its root. The nasal membrane 212 is a medical film. After the nasal plug tube 211 is inserted into the nostril of the child patient, the nasal membrane 212 can wrap around and fit the tip of the child patient's nose to further stabilize the connection and effectively ensure the fit quality between the nasal plug tube 211 and the nasal cavity of the child patient.

[0039] It is understood that the above description is only for illustrating specific embodiments of this application, but the protection scope of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be covered within the scope of disclosure of this application.
