Description

Technical Field

[0001] This application relates to the field of medical device technology, and more particularly to a disposable portable nasal suction device. Background Technology

[0002] Rhinoplasty is a general term for a series of cosmetic nasal surgeries, including rhinoplasty, hump nose and hook nose cosmetic surgery, nasal tip and tip cosmetic surgery, columella and nostril cosmetic surgery, nasal ala defect repair surgery, nasal defect repair surgery, etc. For aesthetic purposes, the surgical incision is made in the nasal vestibule, columella, etc. To reduce incision bleeding and promote the adhesion of the nasal mucosa to the nasal septum and other tissues after surgery, sterile cotton balls are often used to pack the nasal cavity for 2 to 3 days after rhinoplasty. During the packing period, the surgeon will cut a section of medical catheter and place it in the nasal cavity (between the nasal mucosa and the cotton ball, called a "ventilation tube") to ensure nasal ventilation.

[0003] In clinical applications, negative pressure suction devices have been widely used. Currently, it is common to connect a negative pressure suction device to a disposable suction catheter and suction secretions through the nasal "ventilation tube". However, some problems exist during use, including unstable negative pressure. The negative pressure provided by the wall-mounted treatment belt is unstable, and the negative pressure needs to be adjusted before each suction. If the suction negative pressure is too low, it will affect the suction effect and increase the suction time and frequency. If the suction negative pressure is too high, it may cause the "ventilation tube" to shift and damage the nasal mucosa. The operation is inconvenient. The wall-mounted negative pressure device used in the ward needs to be connected to the hospital's negative pressure center. Before the suction operation, the negative pressure drainage meter, collection bucket and disposable suction catheter need to be connected. The steps are cumbersome. In addition, the suction tube of the conventional disposable suction catheter is too long, which is inconvenient to operate. At the same time, it is inconvenient to adjust the pressure during the suction, and the pressure adjustment is not very accurate. Patient fear. The prolonged suction time and frequency, as well as the loud noise when the wall-mounted negative pressure suction is working, will cause discomfort to patients and cause fear.

[0004] Therefore, this application proposes a disposable portable transnasal suction device. Utility Model Content

[0005] This application proposes a disposable portable nasal suction device to address the problems mentioned in the background art. It is manually operated and utilizes atmospheric pressure to aspirate nasal secretions. A relatively stable pressure (the force of pulling the syringe piston handle) and a suitable pressure-bearing area (10ml syringe) are achieved, preventing displacement of the "ventilation tube" or even damage to the nasal mucosa due to excessive suction pressure, as well as insufficient suction pressure leading to ineffective suction. The integrated design allows for immediate use and is easy to operate. This design eliminates the need for a negative pressure suction device (including connecting a negative pressure drainage meter, a collection container, and a disposable suction tube). The device is individually packaged, integrated, and readily available. Its simple structure and reasonable suction tube length design facilitate easy operation, saving time and effort, promoting patient comfort, and solving the problem of inconvenient operation. The design of an exhaust component avoids repeated insertion of the suction tube into the nasal cavity "ventilation tube," alleviating patient fear and greatly improving the device's practicality.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] A disposable portable nasal aspiration device includes a nasal aspiration device body, which is composed of three parts: a front end, a middle part, and a rear end. The front end includes a nasal secretion aspiration catheter and a middle part. The middle part includes a nasal secretion storage device, a three-way valve, and an exhaust port. The rear end includes a 10ml syringe and a syringe piston handle.

[0008] In a preferred embodiment, the nasal secretion suction catheter is fixedly connected to the top of the nasal secretion storage container, and the nasal secretion suction catheter has a side hole.

[0009] By incorporating a nasal secretion suction catheter, nasal secretions are aspirated into a nasal secretion storage device, thereby enhancing the device's practicality.

[0010] In a preferred embodiment, the bottom end of the nasal secretion storage device is fixedly connected to the top end of a three-way valve via a connecting tube, and the three-way valve is provided with an exhaust port.

[0011] By closing the three-way valve, opening the vent, and pushing the syringe piston handle to release the air and then drawing in again, the practicality of the device is improved.

[0012] In a preferred embodiment, the bottom end of the three-way valve is fixedly connected to the top end of the 10ml syringe, and the syringe piston handle is slidably connected inside the 10ml syringe;

[0013] The device's usability is enhanced by slowly pulling the syringe plunger by hand to extract nasal secretions.

[0014] In a preferred embodiment, the syringe piston handle is made of silicone material and is in close contact with the inner wall of the 10ml syringe;

[0015] By making the periphery of the syringe piston handle with silicone material, the sealing performance is improved, thereby enhancing the device's practicality.

[0016] In a preferred embodiment, the nasal secretion suction catheter is a flexible tube;

[0017] By making the nasal secretion suction catheter into a soft tube, it is easier to gently insert the suction catheter into the nasal cavity "airway", thereby improving the practicality of the device.

[0018] The beneficial effects of this application are:

[0019] 1. This disposable portable nasal suction device is manually driven and uses atmospheric pressure to aspirate secretions from the nasal cavity. It uses relatively stable pressure (the force of pulling the syringe piston handle) and a stable and suitable force-bearing area (10ml syringe) to form a relatively stable pressure, avoiding the problem of displacement of the "air tube" or even damage to the nasal mucosa due to excessive suction pressure, as well as the problem of insufficient suction pressure to achieve the suction effect, thus greatly improving the practicality of the device.

[0020] 2. This disposable portable nasal suction device features an integrated design, is readily available for use, and is easy to operate. This design eliminates the need for a negative pressure suction device (including a connection to the negative pressure drainage meter, a collection container, and a disposable suction catheter, etc.). The device is individually packaged, with an integrated design, simple structure, and a rationally designed suction catheter length. It is easy to operate, saves time and effort, promotes patient comfort, and solves the problem of inconvenient operation. The design of an exhaust component avoids repeated insertion of the suction catheter into the nasal cavity as a "ventilation tube," alleviating patient fear and greatly enhancing the device's practicality.

[0025] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0026] Reference Figure 1-3 A disposable portable nasal aspiration device includes a nasal aspiration device body 1, which is composed of three parts: a front end 11, a middle part 12, and a rear end 13. The front end 11 includes a nasal secretion aspiration catheter 111 and a middle part 12. The middle part 12 includes a nasal secretion storage 121, a three-way valve 122, and an exhaust port 123. The rear end 13 includes a 10ml syringe 131 and a syringe piston handle 132.

[0027] The nasal secretion suction catheter 111 is fixedly connected to the top of the nasal secretion storage container 121, and a side hole 112 is provided on the nasal secretion suction catheter 111. By setting the nasal secretion suction catheter 111, nasal secretions are aspirated into the nasal secretion storage container 121, thereby improving the practicality of the device.

[0028] The bottom end of the nasal secretion storage device 121 is fixedly connected to the top end of the three-way valve 122 via a connecting tube. The three-way valve 122 is provided with an exhaust port 123. By closing the three-way valve 122 and opening the exhaust port 123, the syringe piston handle 132 is pushed to release air and then aspirate again, thereby improving the practicality of the device.

[0029] The bottom end of the three-way valve 122 is fixedly connected to the top end of the 10ml syringe 131, and the syringe piston handle 132 is slidably connected inside the 10ml syringe 131; by slowly pulling the syringe piston handle 132 by hand, nasal secretions can be drawn out, thereby improving the practicality of the device.

[0030] The syringe piston handle 132 is made of silicone material on the outside, which is in close contact with the inner wall of the 10ml syringe 131. By making the outside of the syringe piston handle 132 of silicone material, the sealing performance is improved, thereby enhancing the practicality of the device.

[0031] The nasal secretion suction catheter 111 is made of a soft tube; by making the nasal secretion suction catheter 111 a soft tube, it is easier to gently insert the suction catheter into the nasal cavity “ventilation tube”, thereby improving the practicality of the device.

[0032] Working principle: When aspirating nasal secretions, the patient sits upright. The suction catheter is gently inserted into the nasal "ventilation tube." Then, the patient slowly pulls the syringe plunger 132 to aspirate nasal secretions. If secretions remain and need to be aspirated again, first close the three-way valve 122, then open the vent 123, push the syringe plunger 132 to release air, and then aspirate again. The aspirated secretions are collected in the syringe for later processing. The manual aspiration mechanism utilizes atmospheric pressure to aspirate nasal secretions. A relatively stable pressure (the force of pulling the syringe plunger 132) and a suitable pressure-bearing area (10ml syringe 131) are maintained, preventing displacement of the "ventilation tube" or even damage to the nasal mucosa due to excessive suction pressure, as well as insufficient suction pressure.

[0033] Manual suction creates negative pressure, providing stable and safe pressure. Replacing wall-mounted negative pressure with manual suction, this method ensures stable pressure during the suction process, reducing the risk of airway displacement and nasal mucosal damage, thus making nasal suction safer. The integrated design allows for immediate use and is easy to operate. This design eliminates the need for a separate negative pressure suction device (including connecting the negative pressure drainage meter, collection container, and disposable suction catheter, etc.). The device is individually packaged, with a simple structure and a rationally designed suction catheter length, facilitating easy operation, saving time and effort, and promoting patient comfort. The manual negative pressure allows for faster and more effective suction of nasal secretions, reducing suction time and frequency, and enhancing patient comfort. This product avoids the problem of loud noise during wall-mounted negative pressure operation, preventing patient fear. Its design uses a manually driven negative pressure system instead of the traditional wall-mounted treatment strip, providing stable negative pressure that is less likely to cause "ventilation tube" displacement or nasal mucosal damage, making it safer for clinical use. It is also disposable, reducing the risk of infection. The stable negative pressure and suitable suction tube length make suctioning nasal secretions more effective. Individually packaged and with an integrated design, it is easy to use, saving time and effort. The integrated design and suitable suction tube length solve the problem of inconvenient operation. The exhaust component prevents repeated insertion of the suction tube into the nasal cavity "ventilation tube," alleviating patient fear.
