Abstract
Description
Technical Field
[0001] This utility model relates to the field of emergency medicine technology, and in particular to an emergency vomiting device. Background Technology
[0002] In the emergency room, when a patient has food poisoning, it is necessary to induce vomiting. This is usually done by gently stimulating the posterior pharyngeal wall with a tongue depressor, spoon handle, or other vomiting devices. However, because the posterior pharyngeal wall is soft, it is difficult to control the force when stimulating it, which can easily lead to excessive force and damage to the posterior pharyngeal wall. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as difficulty in controlling the force, which can easily lead to excessive force and damage to the posterior pharyngeal wall. This invention provides an emergency vomiting device.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: Design an emergency vomiting device, including a connecting sleeve, one end of which is connected to an air bladder, a piston abutting inside the connecting sleeve, a push rod fixedly connected to the piston, a push part fixedly connected to the push rod, a fixing part fixedly connected to the connecting sleeve, and two unfolding plates connected to the fixing part via a moving mechanism.
[0005] Preferably, a valve is provided on the connecting sleeve.
[0006] Preferably, the moving mechanism includes a limiting sleeve, which is fixedly connected to the fixed part. Both ends of the limiting sleeve are provided with moving rods, and the two moving rods are respectively fixedly connected to the two unfolding plates. The two unfolding plates are each hinged with a hinge rod, and the two hinge rods are adjusted by an adjusting mechanism.
[0007] Preferably, each of the two movable rods is provided with a roller, and the roller abuts against the inner wall of the limiting sleeve.
[0008] Preferably, the adjusting mechanism includes a threaded section, which is disposed on the connecting sleeve. A threaded sleeve is threadedly connected to the threaded section, and a bearing is fixedly connected to the outer wall of the threaded sleeve. The outer ring of the bearing is hinged to the hinge rod.
[0009] Preferably, a retaining post is fixedly connected to the threaded sleeve.
[0010] Preferably, a retaining ring is fixedly connected to the connecting sleeve, and a limiting part is rotatably connected to the retaining ring via a pin. An iron sheet is fixedly connected to the retaining ring.
[0011] The present invention proposes an emergency vomiting device, which has the following advantages: by grasping the connecting sleeve and pushing the pushing part to move, the piston is driven to move, and the air in the connecting sleeve is squeezed into the air bladder, causing the air bladder to expand and slowly contact the posterior pharyngeal wall to induce vomiting, thereby avoiding excessive force and damage to the posterior pharyngeal wall.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0015] Example 1: Refer to Figure 1-3 An emergency emetic device includes a connecting sleeve 10, one end of which is connected to an air bladder 1. A piston 3 is abutted inside the connecting sleeve 10, a push rod 6 is fixedly connected to the piston 3, a push part 7 is fixedly connected to the push rod 6, and a fixing part 11 is fixedly connected to the connecting sleeve 10. Two unfolding plates 4 are connected to the fixing part 11 through a moving mechanism. By grasping the connecting sleeve 10 and pushing the push part 7 to move, the piston 3 is moved, squeezing the air in the connecting sleeve 10 into the air bladder 1, causing the air bladder 1 to inflate and slowly contact the posterior pharyngeal wall, thus inducing emetic action and avoiding damage to the posterior pharyngeal wall caused by excessive force.
[0016] A valve 2 is connected to the connecting sleeve 10. The valve 2 is used to discharge air from the connecting sleeve 10, thereby reducing the portion of the push rod 6 that protrudes from the connecting sleeve 10 and shortening the length of the device.
[0017] Example 2: Refer to Figure 1-3 In another preferred embodiment of this utility model, based on embodiment 1, the moving mechanism includes a limiting sleeve 9, which is fixedly connected to the fixing part 11. Moving rods 8 are provided at both ends of the limiting sleeve 9, and the two moving rods 8 are respectively fixedly connected to two unfolding plates 4. A hinge rod 5 is hinged to each of the two unfolding plates 4. The two hinge rods 5 are adjusted by an adjusting mechanism. Rollers are provided on each of the two moving rods 8, and the rollers abut against the inner wall of the limiting sleeve 9. The adjusting mechanism includes a threaded section 14, which is provided on the connecting sleeve 10. A threaded sleeve 12 is threadedly connected to the threaded section 14. A bearing 13 is fixedly connected to the outer wall of the threaded sleeve 12. The outer ring of the bearing 13 is hinged to the hinge rod 5. By rotating the grip column, the threaded sleeve 12 will rotate, thereby adjusting the position of the threaded sleeve 12 on the threaded section 14, changing the tilt angle of the hinge rod 5, and causing the two unfolding plates 4 to move in opposite directions, opening the patient's mouth and effectively ensuring that the patient will not close their mouth when resisting, thus ensuring the effect of vomiting.
[0018] A gripping post is fixedly connected to the threaded sleeve 12 to grip and drive the threaded sleeve 12 to rotate.
[0019] During vomiting, the device is placed in the patient's mouth. One hand holds the connecting sleeve 10, while the other hand rotates the holding column, causing the threaded sleeve 12 to rotate. This adjusts the position of the threaded sleeve 12 on the threaded section 14, changing the tilt angle of the hinge rod 5. This causes the two unfolding plates 4 to move in opposite directions, opening the patient's mouth. Then, the pushing part 7 is pushed, which in turn moves the piston 3, squeezing the air in the connecting sleeve 10 into the airbag 1. This causes the airbag 1 to inflate, and the airbag 1 slowly contacts the posterior pharyngeal wall, thus inducing vomiting.
[0020] Example 3: Reference Figure 1-4 In another preferred embodiment of this utility model, based on embodiment 1, a retaining ring is fixedly connected to the connecting sleeve 10. A limiting part 15 is rotatably connected to the retaining ring via a pin. An iron sheet 16 is fixedly connected to the retaining ring. The iron sheet 16 is coated with anti-rust paint to prevent corrosion. The attraction between the iron sheet 16 and the limiting part 15 will fix the limiting part 15, thereby limiting the piston 3 and preventing the piston 3 from detaching from the connecting sleeve 10. When it is necessary to disinfect and clean the piston 3 and the connecting sleeve 3, the limiting part 15 is rotated to release the limiting of the piston 3, and the pushing part 7 is pulled to remove the piston 3.
[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
