Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a nasal foreign body removal device. Background Technology

[0002] Nasal foreign bodies are very common in clinical practice, especially children who like to put their toys into their nostrils. After a foreign body is inserted into the nasal cavity, it can usually be expelled by blowing the nose. However, in some cases, the foreign body is too large or adheres to the nasal mucosa, and it needs to be removed with tools.

[0003] Currently, the removal of foreign objects from the nasal cavity is generally done by inserting forceps into the patient's nasal cavity and using the forceps to grasp the foreign object, thereby pulling it out of the patient's nasal cavity.

[0004] However, the forceps for foreign bodies have a relatively large head, limiting the operating space after insertion into the patient's nasal cavity, making it difficult to grasp the foreign body, and the operation is quite challenging and can easily cause discomfort to the patient. In particular, children, who are a high-risk group for nasal foreign bodies, are often unable to cooperate in removing foreign bodies due to fear, which can easily cause the foreign body to be pushed deeper into the nasal cavity or even aspirated into the trachea, resulting in serious consequences of tracheal foreign body aspiration. Utility Model Content

[0005] The purpose of this invention is to provide a nasal foreign body removal device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A nasal foreign body removal device, comprising:

[0008] The hose has guide wire holes inside and graduations on its surface.

[0009] An airbag is located at one end of the hose;

[0010] The guide wire is inserted into the inside of the guide wire hole, and one end of the guide wire is connected to a collar.

[0011] Preferably, the hose is flexible and supportive, with an internal vent tube and an inflation tube connected to its surface.

[0012] Preferably, the guide wire hole extends through both ends of the flexible tube.

[0013] Preferably, the starting point of the scale is located at the end of the hose.

[0014] Preferably, the airbag is positioned at the starting point of the scale, and the airbag is connected to the inflation tube through a vent tube inside the hose.

[0015] Preferably, the guide wire passes through the guide wire hole, and the diameter of the guide wire is half the diameter of the guide wire hole.

[0016] Preferably, the collar and guidewire are an integral structure, with the collar located at the end of the hose near the airbag.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. By incorporating an airbag, when removing foreign objects from the nasal cavity, the end of the tubing guides the airbag through one side of the foreign object. Inflation is then performed through the inflation tube, causing the airbag to inflate until it contacts the side wall of the patient's nasal cavity. At this point, the tubing pulls the airbag outwards from the patient's nasal cavity, thus removing the foreign object. In this invention, by inserting the airbag through the foreign object before inflating it, the airbag inflates and pushes the foreign object forward, preventing it from falling into the lower airway through the posterior nasal cavity. This improves safety while requiring minimal operating space, simplifying operation, and reducing patient discomfort.

[0019] 2. By setting up a guidewire and a collar, when the gap between the foreign object and the nasal cavity wall is small, the guidewire is pushed so that the collar passes through the side of the foreign object. Then, the collar is pulled into the guidewire hole by the guidewire. Due to the compression of the guidewire hole sidewall, the diameter of the collar gradually decreases, eventually trapping the foreign object. Then, the foreign object can be pulled out by the guidewire and the tubing. This allows it to adapt to a smaller operating space and can also remove more stubborn foreign objects.

[0022] In the diagram: hose 1, guide wire hole 11, scale 12, air bag 2, inflation tube 3, guide wire 4, collar 41. Detailed Implementation

[0023] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings and examples.

[0024] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0025] Please see the appendix Figure 1 To be continued Figure 2As shown, this utility model provides a nasal foreign body removal device, comprising: a flexible and supportive tube 1, an internal ventilation tube, an inflation tube 3 connected to the surface of the tube 1, a guide wire hole 11 extending through both ends of the tube 1, and graduations 12 on the surface of the tube 1, with the starting point of the graduations 12 located at the end of the tube 1; and an airbag 2 disposed at one end of the tube 1, positioned at the starting point of the graduations 12, and connected to the inflation tube 3 via the ventilation tube inside the tube 1. Guide wire 4 is inserted into the inside of guide wire hole 11. Guide wire 4 passes through guide wire hole 11 and the diameter of guide wire 4 is half the diameter of guide wire hole 11. One end of guide wire 4 is connected to collar 41. Collar 41 and guide wire 4 are integral structures. Collar 41 is located at the end of hose 1 near airbag 2.

[0026] This utility model proposes a nasal foreign body removal device. In use, one end of the flexible tube 1 with an airbag 2 is inserted into the patient's nasal cavity, allowing the end of the flexible tube 1 to drive the airbag 2 through one side of the foreign body. Then, air is inflated into the airbag 2 through the inflation tube 3, causing the airbag 2 to expand to contact the side wall of the patient's nasal cavity. At this time, the flexible tube 1 pulls the airbag 2 out of the patient's nasal cavity, allowing the airbag 2 to remove the foreign body from the patient's nasal cavity. It requires little operating space, is simple and convenient to operate, has a high safety factor, and reduces patient discomfort.

[0027] As a further improvement of this utility model, by setting guide wire 4 and collar 41, when the gap between the foreign object and the side wall of the patient's nasal cavity is small, the tubing 1 has difficulty driving the airbag 2 through. At this time, after the end of the tubing 1 reaches the position of the foreign object, the guide wire 4 is pushed so that the collar 41 passes through the side of the foreign object. Then, the guide wire 4 pulls the collar 41 into the inside of the guide wire hole 11. Due to the compression of the side wall of the guide wire hole 11, the diameter of the collar 41 gradually decreases, and finally the foreign object is trapped. Then, the foreign object can be pulled out by the guide wire 4 and the tubing 1, so that it can adapt to a smaller operating space and can remove more stubborn foreign objects.

[0028] As a further improvement of this utility model, by setting a scale 12 on the surface of the flexible tube 1, the length of the flexible tube 1 inserted into the patient's nasal cavity can be determined according to the scale 12, thereby avoiding the partial process of the flexible tube 1 being inserted into the patient's nasal cavity and causing harm to the patient.

[0029] Working Principle: Nasal foreign bodies are very common in clinical practice, especially among children who like to stuff their toys into their nostrils. This invention proposes a nasal foreign body removal device. In use, one end of the flexible tube 1 with an airbag 2 is inserted into the patient's nasal cavity, allowing the end of the flexible tube 1 to drive the airbag 2 through one side of the foreign body. Then, air is inflated into the airbag 2 through the inflation tube 3, causing the airbag 2 to expand until it contacts the side wall of the patient's nasal cavity. At this point, the flexible tube 1 pulls the airbag 2 out of the patient's nasal cavity, allowing the airbag 2 to remove the foreign body from the patient's nasal cavity. When the gap between the foreign body and the side wall of the patient's nasal cavity is small, the flexible tube 1 has difficulty driving the airbag 2 through. In this case, after controlling the end of the flexible tube 1 to reach the position of the foreign body, the guide wire 4 is pushed so that the collar 41 passes through the side of the foreign body. Then, the guide wire 4 pulls the collar 41 into the guide wire hole 11. Due to the compression of the side wall of the guide wire hole 11, the diameter of the collar 41 gradually decreases, eventually trapping the foreign body. Finally, the foreign body is pulled out through the guide wire 4 and the flexible tube 1.
