Description

TECHNICAL FIELD

[0001] The utility model relates to an oxygen tube, in particular to a protective oxygen inhalation tube for infants. BACKGROUND

[0002] A nasal oxygen tube is a medical device used to provide oxygen, usually for patients who have difficulty breathing or need oxygen therapy. It is a flexible tube that connects to an oxygen source at one end and delivers oxygen through insertion into the patient's nostrils. Using a nasal oxygen tube ensures that the patient can inhale enough oxygen through the nostrils to support their breathing and life activities. The existing nasal oxygen tube has various structural forms, including double-nose type, head ring type, ear ring type, single-nose type, etc., and the basic structure is composed of a trumpet mouth, a nasal plug, a head ring, a tee joint, an adjusting buckle, a nasal catheter, a connecting catheter, and a two-way joint. When in use, the trumpet mouth end of the nasal oxygen tube is connected to an oxygen inhalation device, the head ring or ear ring is hung on the head or ear, and the nasal plug is inserted into the nostril to inhale oxygen.

[0003] Infants' body tissues and organs have not fully matured, and their tolerance to hypoxia is relatively poor. Brain cells are particularly sensitive to hypoxia, and continuous hypoxia can cause irreversible damage to the nervous system. Nasal catheter oxygen therapy is a common clinical support therapy for correcting hypoxia. It mainly involves inhaling oxygen with a higher oxygen concentration than air through a nasal catheter to increase arterial oxygen partial pressure, blood oxygen saturation, and oxygen content to correct hypoxemia, ensure oxygen supply to tissues, alleviate tissue hypoxia, promote tissue metabolism, maintain body life activities, and ultimately achieve the purpose of alleviating tissue hypoxia. Bilateral nasal oxygen tube oxygen therapy is a common clinical oxygen therapy method for pediatric patients. However, due to the small age and restlessness of infants, or their lack of cooperation, they may grab and pull the nasal oxygen tube. Additionally, the continuous input of oxygen through the nasal oxygen tube can cause discomfort in the nose. This is mainly due to two reasons: first, the existing nasal plug's air outlet is not reasonably designed, which can cause discomfort for the patient. Second, the material of the existing nasal plug can also cause discomfort when it comes into contact with the inside of the patient's nasal cavity. This increases the patient's distress and resistance. Furthermore, since infants cannot express themselves normally, they cannot communicate the oxygen supply situation. Therefore, if the oxygen supply fails, medical staff may not be able to detect it in a timely manner, resulting in low safety. Additionally, due to the lack of firmness of the adhesive, the nasal oxygen tube often comes off, which requires nurses to repeatedly secure it, increasing their workload and causing medical adhesive dermatitis in the infant due to repeated application and removal of the adhesive. The tube can also cause injuries to the infant's face and ears. SUMMARY

[0004] The utility model aims to provide a protective oxygen inhalation tube for infants to solve the above problems.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] like Figures 1-4 As shown, a protective oxygen inhalation tube for infants and young children includes a flexible tube 1 with a rigid plastic tube 2 centrally located on it, and air outlets 3 symmetrically opened on the rigid plastic tube 2.

[0027] It also includes two rubber damping sleeves 4, which are arranged symmetrically about the center of the two air outlets 3 and are connected to the rigid plastic tube 2 by plugging.

[0028] Two rubber damping sleeves 4 are provided with a connecting part 41 at one end of adjacent air outlet 3, and a nose wing fixing piece 42 is provided at the end of the connecting part 41.

[0029] Specifically, the rigid plastic tube 2 is equipped with a philtrum silicone pad 6 located between two air vents 3. When worn, the philtrum silicone pad 6 contacts the philtrum of the child, and because it is made of silicone, it provides a certain degree of damping.

[0030] In the above-mentioned technology, the rubber damping pipe sleeve 4 is inserted with the hard plastic pipe 2, and the damping provided by the rubber damping pipe sleeve 4 can adjust the spacing between the two rubber damping pipe sleeves 4, so that the nasal ala fixing piece 42 is attached to the nasal ala of the child, thereby achieving the effect of clamping, positioning and fixing, thereby avoiding the trouble of fixing the oxygen tube of the child's nasal cavity by using adhesive tape in clinic.

[0031] It should be noted that the nasal ala fixing piece 42 in the above-mentioned embodiment is a circular rectangular structure. The contact area with the nasal ala of the child can be increased to ensure the clamping effect.

[0032] As a further provided embodiment of the utility model, the outer wall of the hose 1 is provided with a threaded silica gel wire 5. Thus, the damping after wearing is increased, the slipping is avoided, and the face and ear of the infant are also avoided from being injured.

[0033] As a further provided embodiment of the utility model, the input end of the hose 1 is fixedly provided with a plug-in end seat 7.

[0034] The hose 1 is provided with a low-temperature resistance sheet 8 distributed close to one plug-in end seat 7, and the low-temperature resistance sheet 8 is provided with a USB interface lead wire 81 extending to the outside of the hose 1.

[0035] Specifically, after the installation and wearing of the hose 1 are completed in the use process, the USB interface lead wire 81 is connected with the power bank, so as to start the low-temperature resistance sheet 8, and the low-temperature resistance sheet 8 heats the passing oxygen, and the temperature of the low-temperature resistance sheet 8 is maintained at 32-36℃. The low-temperature resistance sheet 8 in the embodiment belongs to an existing product, and the detailed operation principle will not be described in detail.

[0036] As a further provided embodiment of the utility model, the rubber damping pipe sleeve 4 is specifically a hard pipe, and the hard pipe is provided with a notch, and the notch is provided with an elastic piece.

[0037] The elastic piece is divided into an arc-shaped part 43 and a V-shaped connecting part 44 according to the structure, one end of the V-shaped connecting part 44 is connected with one end of the arc-shaped part 43, and the other end is connected with the side wall of the notch.

[0038] In the default state of the elastic piece, the arc top of the arc-shaped part 43 faces the inside of the hard pipe.

[0039] Specifically, the rubber damping pipe sleeve 4 in the embodiment is specifically a hard pipe, the outside of the hard pipe is provided with a silica gel coat, and a bulge is formed in the notch. When the finger pulp presses on the bulge, the finger pulp will extrude and deform the two V-shaped connecting parts 44, and the V-shaped connecting parts 44 will be deformed towards the inside of the hard pipe. Figure 4The two opposite direction arrows move, at this time the arc-shaped part 43 is pulled away from the hard pipe, at this time the extrusion force on the hard plastic pipe 2 is removed, at this time the rubber damping pipe sleeve 4 can move.

[0040] When the negative pressure of the finger is removed, the V-shaped connecting part 44 returns to Figure 4 The state is shown, the arc top of the arc-shaped part 43 faces the hard pipe, the hard plastic pipe 2 is extruded, and locking is performed.

[0041] The above only describes some exemplary embodiments of the utility model by way of illustration, without doubt, for ordinary skilled in the art, under the condition that the spirit and scope of the utility model are not deviated, the described embodiments can be modified in various different ways.
