Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary devices, and in particular to a manually operated emergency suction device. Background Technology

[0002] A suction device is a medical device used to clear secretions from the airway to keep it open. It is commonly used in hospitals, clinics, and home care, especially for patients who are unable to cough up phlegm due to illness or surgery. The suction device works by using negative pressure to remove secretions from the airway.

[0003] Currently, manually operated suction devices mainly consist of a syringe and a suction tube (the suction tube is used to directly insert into the airway to remove secretions such as sputum to maintain airway patency). This combination structure is relatively simple. When the suction tube is removed, negative pressure is generated in the airway and throat. As a result, the sputum in the suction tube may flow back under the negative pressure, which affects the suctioning process. Furthermore, it is not easy to control the insertion depth of the suction tube, which can easily cause discomfort. Utility Model Content

[0004] The purpose of this invention is to solve the problem that sputum in the suction tube may flow back under negative pressure in the prior art, and to propose a manually operated emergency suction device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A manually operated emergency suction device includes a syringe and a funnel-shaped outer tube fixedly connected to one end of the syringe. A piston rod is slidably mounted on the inner wall of the syringe. A suction tube is fixed to the constricted end of the funnel-shaped outer tube, and the end of the suction tube has an opening. A blocking component is provided inside the funnel-shaped outer tube. A sleeve is slidably sleeved on the outer wall of the suction tube. A limiting plate is fixedly connected to the sleeve, and an adjustment part is provided on the funnel-shaped outer tube to drive the sleeve to slide along the outer wall of the suction tube.

[0007] To prevent sputum backflow, preferably, the blocking component includes a funnel-shaped inner tube fixedly connected inside the funnel-shaped outer tube. The funnel-shaped inner tube is elastic. The outer wall of the funnel-shaped outer tube is provided with a slot, and a button is inserted into the slot. The end of the button is attached to the outer wall of the funnel-shaped inner tube. The fixed end of the suction tube extends into the funnel-shaped inner tube.

[0008] To further improve the usability of the button, a protrusion is fixedly connected to the inner wall of the funnel-shaped outer tube. One side of the protrusion is attached to the outer wall of the funnel-shaped inner tube, and the protrusion and the button are located on opposite sides of the funnel-shaped inner tube.

[0009] To facilitate adjustment of the insertion depth of the suction catheter, the adjustment unit further includes a support fixedly connected to the outer wall of the funnel-shaped outer tube. An internally threaded tube parallel to the syringe is rotatably connected to the support. A screw is internally threaded onto the internally threaded tube, and one end of the screw is fixedly connected to a limiting plate.

[0010] To facilitate operation of the internally threaded tube, the outer wall of the internally threaded tube is further fitted with an anti-slip sleeve, and the internally threaded tube and the button are respectively located on both sides of the funnel-shaped outer tube.

[0011] To reduce discomfort to the user caused by the limiting plate, preferably, the limiting plate is elongated and strip-shaped, and both ends of the limiting plate are fixedly connected to silicone pads, with the silicone pads facing the end of the suction tube.

[0012] To ensure the efficiency of suctioning, the opening is preferably located on the outer wall of the end of the suction tube, and the opening is triangular in shape.

[0013] To facilitate handling the syringe, preferably, a cylindrical handle is fixedly connected to the outer wall of the funnel-shaped outer tube, and the cylindrical handle is perpendicular to the syringe.

[0014] To facilitate the suctioning process, preferably, an annular plate is fixedly connected to the limiting plate, and an LED bead facing the end of the suction tube is fixedly installed on the annular plate.

[0015] To facilitate observation of the aspirated sputum, the syringe is preferably made of transparent plastic.

[0016] Compared with the prior art, this utility model provides a manually operated emergency suction device, which has the following beneficial effects:

[0017] 1. This manually operated emergency suction device, by pressing the button, the button will press against the outer wall of the funnel-shaped inner tube, causing the funnel-shaped inner tube to be flattened. At this time, the suction tube is pulled out. Even if the suction tube is under negative pressure, the sputum in the syringe and suction tube is not easy to flow back, ensuring the efficiency of the suction work.

[0018] 2. This manually operated emergency suction device allows the limiting plate to move away from the oral cavity by rotating the internal threaded tube, increasing the distance between the limiting plate and the end of the suction tube. Conversely, reversing the internal threaded tube decreases the distance between the limiting plate and the end of the suction tube, making it easy to adjust the insertion depth of the suction tube and making it more flexible and safe to use.

[0019] The parts of this device not described herein are the same as or can be implemented using existing technology. This utility model can prevent sputum in the syringe and suction tube from flowing back, ensuring the efficiency of sputum suction. It also allows for easy adjustment of the insertion depth of the suction tube, making it more flexible and safe to use. Attached Figure Description

[0026] 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.

[0027] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] Example:

[0029] Reference Figures 1-5This utility model provides a manually operated emergency suction device, including a syringe 1 for storing sputum. The syringe 1 is made of transparent plastic and includes a funnel-shaped outer tube 2, the wide end of which is fixedly connected to one end of the syringe 1. A piston rod 6 is slidably installed on the inner wall of the syringe 1. The piston rod 6 includes a piston and a push rod. A suction tube 4 for suctioning sputum is fixedly installed at the narrow end of the funnel-shaped outer tube 2. The end of the suction tube 4 is provided with an opening 9 for suctioning sputum. A blocking component is provided inside the funnel-shaped outer tube 2. A sleeve 10 is slidably sleeved on the outer wall of the suction tube 4. A limiting plate 11 is fixedly connected to the sleeve 10. An adjustment part is provided on the funnel-shaped outer tube 2 to drive the sleeve 10 to slide along the outer wall of the suction tube 4.

[0030] Specifically, during use, the position of the limiting plate 11 is adjusted by adjusting the adjustment part to shorten the distance between the end of the suction tube 4 and the limiting plate 11 to a safe length of about 8cm. Then, the suction tube 4 is inserted into the respiratory tract or throat to begin suctioning sputum. At this time, the limiting plate 11 can be placed on the lips to limit the insertion depth of the suction tube 4. During suctioning, the piston rod 6 is pulled, and negative pressure is generated in the syringe 1, allowing the suction tube 4 to suction sputum through the opening 9. When the depth of the suction tube 4 is insufficient, the insertion depth of the suction tube 4 can be adjusted by adjusting the adjustment part, making it more flexible and convenient to use, and safer. After suctioning, the blocking part can prevent sputum backflow to reduce the impact on the suctioning work.

[0031] The blocking component in this manually operated emergency suction device includes a funnel-shaped inner tube 3 fixedly connected inside the funnel-shaped outer tube 2. The funnel-shaped inner tube 3 is elastic and made of silicone. The outer wall of the funnel-shaped outer tube 2 is provided with a slot 7, and a button 5 is inserted into the slot 7. The end of the button 5 is attached to the outer wall of the funnel-shaped inner tube 3. The fixed end of the suction tube 4 extends into the funnel-shaped inner tube 3.

[0032] Specifically, when it is necessary to remove the suction tube 4, press button 5. Button 5 will press against the outer wall of the funnel-shaped inner tube 3, causing the funnel-shaped inner tube 3 to be flattened. At this time, the suction tube 4 is removed. Even if the suction tube 4 is subjected to negative pressure, the sputum in the syringe 1 and the suction tube 4 will not easily flow back out, ensuring the efficiency of the suctioning work.

[0033] The inner wall of the funnel-shaped outer tube 2 is fixedly connected with a protrusion 8. One side of the protrusion 8 is attached to the outer wall of the funnel-shaped inner tube 3. The protrusion 8 and the button 5 are located on the two sides of the funnel-shaped inner tube 3, respectively.

[0034] Specifically, when button 5 is pressed, the protrusion 8 supports the funnel-shaped inner tube 3, allowing the funnel-shaped inner tube 3 to be stably flattened.

[0035] The adjustment section of the manually operated emergency suction device includes a support 13 fixedly connected to the outer wall of the funnel-shaped outer tube 2. An internally threaded tube 12 parallel to the syringe 1 is rotatably connected to the support 13. A screw 14 is internally threaded to the internally threaded tube 12. One end of the screw 14 is fixedly connected to the limiting plate 11.

[0036] Specifically, when it is necessary to adjust the insertion depth of the suction catheter 4, rotate the internal thread tube 12. The internal thread tube 12 will drive the screw 14 to move towards the syringe 1, and drive the limiting plate 11 and the sleeve 10 to move synchronously. The limiting plate 11 will then move away from the oral cavity, and the distance between the limiting plate 11 and the end of the suction catheter 4 will increase. Conversely, when the internal thread tube 12 is reversed, the distance between the limiting plate 11 and the end of the suction catheter 4 will decrease. This allows for convenient adjustment of the insertion depth of the suction catheter 4, making it more flexible and safe to use.

[0037] The outer wall of the aforementioned internally threaded tube 12 is fixedly fitted with an anti-slip sleeve, and the internally threaded tube 12 and the button 5 are respectively located on both sides of the funnel-shaped outer tube 2, which can prevent mutual interference between the internally threaded tube 12 and the button 5.

[0038] The aforementioned limiting plate 11 is elongated in shape, and silicone pads 15 are fixedly connected to both ends of the limiting plate 11. The silicone pads 15 face the end of the suction tube 4. Therefore, during use, the limiting plate 11 can be pressed against the lips by the silicone pads 15 to reduce the discomfort of the limiting plate 11 to the user.

[0039] The opening 9 is located on the outer wall of the end of the suction tube 4. The opening 9 is triangular in shape, which can improve the efficiency of suctioning sputum.

[0040] The outer wall of the funnel-shaped outer tube 2 is fixedly connected to a columnar handle 18, which is perpendicular to the syringe 1. Due to the setting of the internal thread tube 12 and the button 5, it is inconvenient for the user to pick up the syringe 1. Therefore, during operation, the user can hold the syringe 1 through the columnar handle 18.

[0041] An annular plate 16 is fixedly connected to the aforementioned limiting plate 11. An LED bead 17 facing the end of the suction tube 4 is fixedly installed on the annular plate 16. Thus, during use, the LED bead 17 can illuminate the oral cavity, improving suction efficiency.

[0042] 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.
