Description

Technical Field

[0001] The present invention particularly relates to an oral humidifier. Background Art

[0002] Oral flap grafting is a complex and delicate surgery, mainly used to repair oral and maxillofacial skin and soft tissue defects caused by disease or trauma. It refers to cutting a tissue flap with a vascular pedicle from other parts of the body at the far end, and then anastomosing the vascular pedicle of the tissue flap with the blood vessels in the defect area to repair the wound surface. It is widely used in the treatment of oral cancer. After oral flap transplantation, the patient's mouth is always in an open state due to the large size of the transplanted flap or the particularity of the lesion location, resulting in the inability to close the lips. At the same time, due to the impact of postoperative swallowing function and the influence of the disease, the mouth will be severely dehydrated, affecting the recovery of the flap and reducing the patient's comfort. In addition, for patients who have undergone general anesthesia, six hours after general anesthesia, be careful of causing the patient to inhale, and temporarily cannot drink water, which will also cause the patient's comfort to decrease.

[0003] For example, the Chinese invention patent with publication number CN106039519B provides an oral humidifier for patients with open mouth breathing, including a warm water supply device, a Murphys tube water storage chamber, a soft pipe, and medical gauze. The oral humidifier utilizes the water storage capacity of the Murphys tube, the water absorption capacity of the gauze, and the water supply system of the warm water supply device, so that the gauze can be continuously supplied with water to keep the surface moist. Through the patient's breathing, the moist water is sucked into the oral cavity and airway to keep the mucosa moist.

[0004] However, most existing oral humidifiers only humidify the oral cavity by spraying water mist in a single direction or wetting oral contents. Most of the above humidification methods can only humidify a small area and are not convenient for humidifying a larger range of the oral cavity, resulting in a decrease in the humidification effect. Patients are still prone to feeling unbearable oral dehydration. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention proposes an oral humidifier to solve the technical problem raised in the above background technology that most of the existing oral humidifiers only humidify the oral cavity by spraying water mist in a single direction or wetting the oral contents, and the above humidification methods can mostly only humidify a smaller area, which is not convenient for humidifying a larger range of the oral cavity, thereby resulting in a decrease in the humidification effect, and patients are still prone to feel the unbearable technical problem of oral dehydration.

[0046] The present invention is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present invention and cannot be understood as limiting the scope of protection of the present invention. Technicians in this field can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0047] Example:

[0048] like Figure 1 , 4 As shown, the present invention provides an oral humidifier, including a handle shell 101 and a mask 201, the handle shell 101 is externally connected to a water supply source, a mounting tube 202 is movably provided on the mask 201, one end of the mounting tube 202 is connected to the handle shell 101, and the other end is provided with a humidifying head 203, a plurality of groups of atomizing nozzles 107 are annularly hinged on the humidifying head 203, a water supply pipe 105 is provided in the mounting tube 202, one end of the water supply pipe 105 is connected to the plurality of groups of atomizing nozzles 107, and the other end is connected to the water supply source.

[0049] When in use, the water supply source can be connected to the handle shell 101. When the oral cavity needs to be humidified for a long time, the water supply source can be an external water pipe or water pump that automatically supplies water, so that multiple groups of atomizing nozzles 107 can continuously spray water mist into the oral cavity to humidify the oral cavity. When the oral cavity only needs to be humidified for a short time, the water supply source can be an external water bottle, and the patient can perform humidification work autonomously. The patient can slide the mounting tube 202 on the mask 201 to move the humidifying head 203 into the oral cavity, and the oral cavity can be supported at the same time. A tooth pad 204 made of a flexible material is set on the humidifying head 203 to support the patient's teeth, prevent the humidifying head 203 from sliding in the oral cavity, and increase the comfort of the oral humidifier when in use.

[0050] like Figures 1 to 3 As shown, in this embodiment, a handle 301 protruding from the outside is hinged on the handle shell 101, and the handle 301 is connected to the water supply pipe 105 through a water supply assembly, so that the swing of the handle 301 is converted into pumping water from the water supply source out of multiple groups of atomizing nozzles 107. The water supply assembly includes an arc-shaped water storage shell 102 arranged in the handle shell 101, the water storage shell 102 is connected to the water supply source through a first one-way valve 103, and a second one-way valve 104 connected to the water supply pipe 105 is arranged on the water storage shell 102. An arc-shaped piston rod 302 is arranged on the handle 301, and a piston at one end of the piston rod 302 is slidably arranged in the water storage shell 102. Multiple groups of branch pipes 106 are arranged at one end of the water supply pipe 105, and the multiple groups of branch pipes 106 are respectively connected to multiple groups of atomizing nozzles 107.

[0051] A torsion spring is provided at the hinge between the grip 301 and the handle shell 101, and the grip 301 is driven by the torsion spring to reset after being swung and retracted into the handle shell 101. The grip 301 drives the piston rod 302 to move during the swinging process, so that the piston at one end of the piston rod 302 slides in the water storage shell 102, so that negative pressure is formed in the water storage shell 102 to extract water through the first one-way valve 103, and then the water is discharged to the multiple branch pipes 106 through the second one-way valve 104 and the water supply pipe 105, so that the water is supplied to the atomizing nozzle 107, and finally the water is sprayed out through the atomizing nozzle 107 to moisten the oral cavity.

[0052] like Figure 2 , 3 As shown, in this embodiment, a driving mechanism connected to the multiple groups of atomizing nozzles 107 is provided on the handle 301, and the driving mechanism is used to convert the swing of the handle 301 into driving the multiple groups of atomizing nozzles 107 to swing back and forth along the hinge point between the handle 301 and the humidifying head 203. The driving mechanism includes a winding wheel 306 rotatably arranged in the handle shell 101, and a pull wire 209 is wound on the winding wheel 306. The pull wire 209 passes through the mounting tube 202 and extends into the humidifying head 203. A control component connected to the winding wheel 306 is arranged on the handle 301. The swing of the handle 301 is converted into reciprocating rotation of the driving winding wheel 306 through the control component to drive the pull wire 209 to slide in the mounting tube 202. The control component includes a driving wheel 305 rotatably arranged in the handle shell 101 along its axis, and a gear 304 is arranged on the driving wheel 305. An arc-shaped rack 303 is arranged on the handle 301, and the arc-shaped rack 303 is meshed with the gear 304. It also includes a first linkage rod 307, one end of the first linkage rod 307 is eccentrically hinged to the driving wheel 305, and the other end is eccentrically hinged to the winding wheel 306.

[0053] When the handle 301 is gripped, the handle 301 drives the driving wheel 305 to rotate through the meshing of the arc-shaped rack 303 and the gear 304. During the rotation, the driving wheel 305 drives the winding wheel 306 to reciprocate along its axis through the first connecting rod 307, so that the winding wheel 306 repeatedly retracts and releases the pull wire 209, and a single grip of the handle 301 can control the pull wire 209 to slide in the mounting tube 202 multiple times.

[0054] like Figures 5 to 7As shown, in this embodiment, the driving mechanism also includes a linkage assembly, which is arranged at one end of the pull wire 209 located at the humidifying head 203 to convert the movement of the pull wire 209 into driving the multiple groups of atomizing nozzles 107 to swing. The linkage assembly includes a first hinge seat 108 arranged on the atomizing nozzle 107, and a driving frame 205 is slidably arranged along its axis in the humidifying head 203. One side of the driving frame 205 is circumferentially arranged with multiple groups of second hinge seats 207. The driving frame 205 is connected to the end of the pull wire 209, and also includes multiple groups of circumferentially arranged second linkage rods 208, one end of the second linkage rod 208 is hinged to the first hinge seat 108, and the other end is hinged to the second hinge seat 207. An elastic member 206 is arranged between the side of the driving frame 205 that is away from the multiple groups of second hinge seats 207 and the inner wall of the humidifying head 203.

[0055] By holding the handle 301, the pull wire 209 slides back and forth, and the driving frame 205 slides back and forth in the humidification head 203. During the movement, the driving frame 205 can set multiple groups of second linkage rods 208 to make multiple groups of atomizing nozzles 107 swing along their hinge points on the humidification head 203, so as to humidify the oral cavity more comprehensively, with a larger humidification range, reduced humidification blind spots, and suitable for patients with different needs.

[0056] Specific usage and beneficial effects of the present invention:

[0057] When the oral humidifier is in use, when the patient needs to be humidified for a long time, the water supply source can be connected to an external water pipe to continuously supply water to automatically humidify the oral cavity. When the oral cavity only needs to be humidified intermittently and briefly, the water supply source can be in the form of an external water bottle to autonomously humidify the oral cavity according to the humidification needs. During autonomous control, the patient can wear the mask 201 to protect the oral wound, and when the oral cavity needs to be humidified, the humidifying head 203 can be extended into the patient's oral cavity by sliding the mounting tube 202, and the patient holds the middle area of ​​the humidifying head 203 in his mouth, and then holds the handle 301. During the swinging process, the handle 301 pumps water from the water supply source into the atomizing nozzle 107 through the water supply component, and sprays the water through the atomizing nozzle 107 to humidify the patient's oral cavity. In the process of holding the handle 301, the swing of the handle 301 is converted by the driving mechanism into driving multiple groups of atomizing nozzles 107 to swing back and forth along the hinge point between the handle 301 and the humidifying head 203, so that the water is evenly sprayed to a larger area in the oral cavity. Compared with the traditional method of humidifying the oral cavity by spraying water mist in a single direction or wetting the oral contents, the oral humidifier has a larger humidification range, which can greatly reduce the patient's feeling of dehydration in the oral cavity.
