[0003] The existing spray devices used in respiratory departments are too large, which makes them inconvenient to use as they need to be moved around.
[0004] To address the aforementioned deficiencies, a portable respiratory spray device with publication number CN112870536A is disclosed. This device opens the mouth through a placement mechanism, moves the device into the oral cavity through a mechanism, transports the medication to a telescopic mechanism through a spraying mechanism, and sprays the medication into the throat through the telescopic mechanism. The arc-shaped block can open the patient's mouth more conveniently to spray the medication into the throat.
[0005] In actual use, although the device is small and easy to use, it uses a placement mechanism to facilitate the spraying of drugs. However, the placement mechanism and the support are fixed together, which may cause some patients to experience discomfort when using the placement mechanism due to inconsistent mouth opening angles.
[0006] Therefore, we proposed a portable spraying device that can effectively solve the above problems. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Example 1: This utility model solves the problem that existing placement mechanisms for facilitating drug spraying have a fixed connection between the placement mechanism and the support, which can lead to discomfort for some patients due to inconsistent mouth opening angles. The rotation of gear 4 improves applicability and convenience. The following is disclosed:
[0032] The device includes a housing 1, inside which a sprayer 2 is installed; it also includes: a rotating wheel 3 rotatably connected inside the housing 1, and a gear 4 keyed to the rear end of the rotating wheel 3, with a first toothed sleeve 5 and a second toothed sleeve 6 respectively meshing at the outer ends of the gear 4; the first toothed sleeve 5 and the second toothed sleeve 6 slide inside the housing 1, and the teeth on the first toothed sleeve 5 and the second toothed sleeve 6 are symmetrically arranged; the interiors of the first toothed sleeve 5 and the second toothed sleeve 6 are hollow, and the first toothed sleeve 5 and the second toothed sleeve 6 are arc-shaped; the right side of the first toothed sleeve 5 and the left side of the second toothed sleeve 6 are respectively attached to the interior of the housing 1, and the gear 4 between the first toothed sleeve 5 and the second toothed sleeve 6 is tightly fitted between them; and the total width between the gear 4, the first toothed sleeve 5 and the second toothed sleeve 6 and the width of the opening inside the housing 1 constitutes a sliding engagement mechanism.
[0033] refer to Figures 1 to 4 and Figure 6 The first toothed sleeve 5 and the second toothed sleeve 6 are inserted into the patient's mouth, allowing the patient's teeth to enter their interior. Then, the rotating wheel 3 is rotated, causing the gear 4 to rotate. This rotation causes the first toothed sleeve 5 and the second toothed sleeve 6 to slide in opposite positions inside the outer casing 1. The movement of the first toothed sleeve 5 and the second toothed sleeve 6 opens the patient's mouth. Then, the sprayer 2 is pressed, causing the medication inside to be sprayed onto the patient's throat, thus treating the patient's breathing position. This method can be adjusted according to different patients, improving patient comfort. Furthermore, its small size makes it easy to carry and use.
[0034] Example 2: This utility model solves the problem in Example 1 where the rotating wheel 3 needs to be continuously pinched to prevent the patient's mouth from closing, making it inconvenient to use. The use of the pawl 7 allows the first toothed sleeve 5 and the second toothed sleeve 6 to self-lock, thus facilitating use. The following is disclosed:
[0035] The inside of the outer casing 1 is rotatably connected to a pawl 7, and the bottom right side of the pawl 7 is arc-shaped. The bottom of the pawl 7 extends into the inside of the slot 8 to form a locking mechanism. The slot 8 is opened at the front end of the rotating wheel 3 at equal angles and is trapezoidal in shape. The top of the pawl 7 is connected to a spring 9, and the top of the spring 9 is connected to the inside of the outer casing 1 to form a limiting mechanism.
[0036] refer to Figure 4 and Figure 5 The rotation of the rotating wheel 3 drives the slot 8 to rotate, which in turn squeezes the pawl 7, causing the pawl 7 to rotate and move inward toward the outer shell 1. The rotation of the pawl 7 disengages from the slot 8, and the rotation of the pawl 7 squeezes the spring 9, causing the spring 9 to compress. After the rotating wheel 3 reaches its position, the force of the spring 9 pushes the pawl 7 into the slot 8 to engage, thus allowing the first toothed sleeve 5 and the second toothed sleeve 6 to be easily fixed, avoiding the need to continuously squeeze the rotating wheel 3 for spraying, thereby improving the ease of use.
[0037] Example 3: This utility model solves the problem of the first toothed sleeve 5 and the second toothed sleeve 6 being difficult to reset in Example 2. By moving the pull rope 10, the reset of the first toothed sleeve 5 and the second toothed sleeve 6 can be facilitated. The following is disclosed:
[0038] The top of the pawl 7 is connected to a pull rope 10, and the top of the pull rope 10 passes through the inside of the spring 9, and the top of the pull rope 10 extends out of the inside of the housing 1 to form a sliding mechanism;
[0039] refer to Figure 4 and Figure 5 After the spraying is completed, by pulling the pull rope 10, the pull rope 10 moves and drives the pawl 7 to rotate. The rotation of the pawl 7 will disengage from the slot 8. Then, by the patient's teeth closing, the patient will apply pressure between the first toothed sleeve 5 and the second toothed sleeve 6, thereby allowing the first toothed sleeve 5 and the second toothed sleeve 6 to reset. This will allow the gear 4 to reverse, thus allowing the first toothed sleeve 5 and the second toothed sleeve 6 to disengage from the patient's mouth, thereby achieving the purpose of rapid separation.
[0040] Working principle: When using this portable spraying device, first, refer to... Figures 1 to 4 and Figure 6 Insert the first toothed sleeve 5 and the second toothed sleeve 6 into the patient's mouth, so that the patient's teeth are inserted into the first toothed sleeve 5 and the second toothed sleeve 6. Then rotate the rotating wheel 3, so that the rotating wheel 3 drives the gear 4 to rotate. Then, by moving the first toothed sleeve 5 and the second toothed sleeve 6, the patient's mouth can be opened. Then press the sprayer 2, so that the medicine in the sprayer 2 is sprayed into the patient's throat. This can be adjusted according to different patients, and because of its small size, it is easy to carry and use.
[0041] refer to Figure 4 and Figure 5The rotation of the rotating wheel 3 drives the slot 8 to rotate, which in turn squeezes the pawl 7. The pawl 7 rotates under pressure and disengages from the slot 8. This causes the spring 9 to be compressed. After the rotating wheel 3 reaches its position, the force of the spring 9 pushes the pawl 7 into the slot 8 to engage, thus avoiding the need to continuously squeeze the rotating wheel 3 for spraying, thereby improving the ease of use.
[0042] refer to Figure 4 and Figure 5 After the spraying is completed, by pulling the pull rope 10, the pull rope 10 moves and drives the pawl 7 to rotate. Then, by the patient's teeth closing, the patient will apply pressure between the first toothed sleeve 5 and the second toothed sleeve 6, thereby allowing the first toothed sleeve 5 and the second toothed sleeve 6 to detach from the patient's mouth, thus achieving the purpose of rapid separation.
[0043] The contents not described in detail in this specification are existing technologies known to those skilled in the art.
