Technical Field
[0001] The utility model relates to the technical field of medical supplies, in particular to a medical mouth expander. Background Art
[0002] In modern healthcare practice, routine oral examinations and care for patients with limited mouth opening or apathy (especially those who have undergone long-term tracheostomies and are unable to cooperate effectively) have always been a major challenge for nursing staff. This group of patients typically includes but is not limited to those suffering from neurological diseases, trauma, and those in intensive care units. They may also have an imbalance in oral flora due to long-term use of broad-spectrum antibiotics, or have decreased immune function after taking immunosuppressive and steroid medications, further increasing the risk of oral infections.
[0003] Oral care for such patients often requires close collaboration among multiple medical staff. For example, one person is responsible for fixing the patient's head and mouth opening, while another is responsible for using lighting equipment, applying medication, etc. This operating mode not only increases the workload of medical staff and reduces care efficiency, but may also cause negative emotions such as anxiety and fear due to the patient's discomfort, further affecting the care effect and the patient's recovery process.

[0025] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below with reference to the accompanying drawings. The drawings illustrate several embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present invention.
[0026] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.
[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0028] See also Figures 1 to 4 The medical mouth expander in the utility model includes an elastic support ring and an adjustment component.
[0029] The elastic support ring includes a left segment 11, an upper segment 12, a right segment 13 and a lower segment 14, and the left segment 11, the upper segment 12, the right segment 13 and the lower segment 14 are connected in sequence to form a flat ring;
[0030] The adjustment assembly includes a threaded rod 21, a fixed sleeve 22 and a nut knob 23. The threaded rod 21 is fixed on the upper segment 12, and the fixed sleeve 22 is fixed on the lower segment 14. The threaded rod 21 and the fixed sleeve 22 are aligned with the center line of the elastic support ring. The nut knob 23 is rotatably connected to the fixed sleeve 22 and threadedly engaged with the threaded rod 21.
[0031] By placing an elastic support ring in the patient's mouth, it helps stabilize the patient's mouth opening, allowing only one medical staff member to complete oral care, reducing their workload and improving care efficiency. Secondly, the design of the adjustment component allows medical staff to flexibly adjust the opening size of the mouth expander according to the size and shape of the patient's mouth, ensuring that the mouth expander fits the mouth of each patient tightly and comfortably, improving the comfort level and patient acceptance during treatment.
[0032] It should be noted that, in this embodiment, the elastic support ring is formed by integral injection molding, has a certain elasticity, and can be deformed under the action of the adjustment component, thereby achieving adjustment of the opening size.
[0033] In actual application, when assembling the mouth expander for a patient, the medical staff can first rotate the nut knob 23 clockwise to shrink the threaded rod 21 relative to the fixed sleeve 22, so that the upper segment 12 and the lower segment 14 are relatively close to each other, thereby reducing the opening of the elastic support ring. During this process, the medical staff will adjust the opening to a suitable size according to the patient's oral size and needs to facilitate subsequent insertion;
[0034] When the opening of the elastic support ring is reduced to the appropriate size, the expander is placed in the patient's mouth and the installation position is adjusted. Then, the nut knob 23 is gradually turned counterclockwise to gradually extend the threaded rod 21 relative to the fixed sleeve 22 until the upper segment 12 and the lower segment 14 are respectively pressed against the patient's upper and lower teeth, completing the fixation of the expander. At this time, medical staff can use a cotton swab to apply medicine, take pathological specimens or perform oral care through the expander. If the mouth opening needs to be further increased, continue to turn the nut knob 23 counterclockwise. However, during the process of increasing the mouth opening, medical staff should pay close attention to the patient's reaction to ensure that the expander does not cause discomfort or pain.
[0035] See Figure 3 The front opening 41 of the elastic support ring is smaller than the rear opening 42. This design allows the elastic support ring to be placed in the patient's mouth like a "funnel", greatly reducing the difficulty of placement.
[0036] Furthermore, the outer periphery of the elastic support ring is recessed to form an occlusal groove. When the elastic support ring is placed in the patient's mouth and adjusted to the appropriate position, the patient's upper and lower teeth naturally fit into or close to this groove. This physical occlusal action not only increases the contact area between the elastic support ring and the patient's mouth, but also further enhances the stability of the elastic support ring within the mouth through the bite force of the teeth.
[0037] See Figure 4A rotating sleeve 24 is fixedly mounted at the bottom end of the nut knob 23. The nut knob 23 is rotatably coupled to the fixed sleeve 22 via the rotating sleeve 24. The end of the rotating sleeve 24, which is away from the nut knob 23, extends out of the fixed sleeve 22 and is fixedly connected to a retaining ring 25. The retaining ring 25 is used to limit the extension and contraction of the rotating sleeve 24 relative to the fixed sleeve 22, preventing the nut knob 23 from moving upward along the threaded rod 21 when the nut knob 23 is rotated, thereby ensuring smooth adjustment of the opening size of the elastic support ring.
[0038] Furthermore, the threaded hole diameter of the nut knob 23 is smaller than the diameter of the rotating sleeve 24 , so that when the threaded rod 21 extends into the rotating sleeve 24 , the threaded rod 21 and the rotating sleeve 24 are spaced apart to avoid friction between the rotating sleeve 24 and the threaded rod 21 .
[0039] See Figure 1 The inner sides of the left segment 11 and the right segment 13 are provided with lighting beads 30. When powered on, the lighting beads 30 can illuminate the patient's oral cavity, providing a clearer and brighter operating field for medical staff. Specifically, the lighting beads 30 are connected to a power switch (not shown) via a power cord, wherein a portion of the power cord can be embedded in the elastic support ring and fixed. Medical staff can operate the power switch to control the lighting or extinguishing of the lighting beads 30.
[0040] In summary, the medical mouth expander in the above-mentioned embodiment of the present invention can assist in fixing the patient's mouth opening by placing an elastic support ring in the patient's mouth, so that only one medical staff member is required to complete the care work of the patient's mouth, reducing the workload of the medical staff and improving the efficiency of care. Secondly, the design of the adjustment component allows the medical staff to flexibly adjust the opening size of the mouth expander according to the size and shape of the patient's mouth, ensuring that the mouth expander can fit the mouth of different patients tightly and comfortably, improving the comfort level and patient acceptance during the treatment process.
