Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a disposable handle-type otoscope. Background Technology

[0002] With the continuous improvement of medical standards, the National Health Commission and various medical institutions are paying increasing attention to nosocomial infections (Nosocomial infections) and the requirements for Nosocomial infection control are becoming increasingly stringent. Currently, when examining the external auditory canal of patients undergoing physical examinations, a simple otoscope is still used. Figure 2 The otoscope shown is an example. Alternatively, patent document CN 202078285 U discloses an ear speculum, mainly composed of a conical trocar. The trocar has an external trocar at its larger diameter end and an internal trocar at its smaller diameter end, with a diaphragm at the end near the internal trocar. Doctors face many problems when using existing otoscopes: 1. They are extremely inconvenient to operate; 2. A large number of patients undergoing physical examinations reuse the otoscope multiple times, and even with iodine swabs, thorough disinfection is not achieved. Currently, physical examination centers require each patient to have their external auditory canal disinfected with iodine swabs before examination. However, due to the large number of patients, long waiting times, and time constraints, coupled with the inconsistent aperture sizes of otoscopes, there is a risk that iodine swabs may not achieve thorough disinfection. If a patient has an infectious disease (such as fungal otitis externa), incomplete disinfection after examination can easily infect the next patient, causing cross-infection within the hospital. This results in significant suffering and unnecessary costs for patients, and also negatively impacts the physical examination center, causing economic losses. The introduction of osmotic devices with electronic handles to the market still results in reusable handles that are difficult to disinfect once contaminated, which can also lead to cross-infection within hospitals.

[0003] There is an urgent need for ENT departments and health checkup centers to develop a disposable handle-type otoscope that can completely solve the problem of cross-infection within hospitals. Utility Model Content

[0004] The present invention aims to overcome the shortcomings of the prior art by providing a disposable handle-type otoscope, which is convenient for doctors to operate during examinations, provides a clearer field of vision, and yields more accurate examination results, thereby completely solving the problem of cross-infection within hospitals.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a disposable handle-type endoscopic device, comprising a conical endoscopic tube and a handle, wherein the large-diameter end of the endoscopic tube is provided with an external endoscopic port and the small-diameter end is provided with an internal endoscopic port, the external endoscopic port being connected to the internal endoscopic port through an endoscopic hole, and the large-diameter end of the endoscopic tube being connected to the handle to form an integrated endoscopic device structure.

[0006] Furthermore, the diameter of the peephole is 2.5mm-5mm.

[0007] Furthermore, the otoscope is made of polyethylene, polypropylene, polyvinyl chloride, polytetrafluoroethylene, or ABS medical plastic.

[0008] Furthermore, the handle's appearance is composed of two intersecting arcs forming a flat structure, with 2-3 oval-shaped cutouts in the middle of the flat handle.

[0009] Beneficial effects: Compared with existing technologies, this novel otoscope can more effectively control and eliminate the incidence of nosocomial infections, reducing unnecessary pain and financial burden on patients. It facilitates the doctor's operation during examinations, providing a wider and clearer field of view and more accurate results. Attached Figure Description

[0013] The following detailed description of the specific implementation of the present invention, in conjunction with preferred embodiments, is as follows: As shown in the accompanying drawings, this embodiment provides a disposable handle-type endoscopic device, including a conical endoscopic tube 1 and a handle 2. The endoscopic tube has an external endoscopic port 1-1 at its large-diameter end and an internal endoscopic port 1-2 at its small-diameter end. The external endoscopic port is connected to the internal endoscopic port through an endoscopic hole 1-3. The handle is connected to the large-diameter end of the endoscopic tube, forming an integrated endoscopic device structure.

[0014] In this preferred embodiment, the diameter of the peephole is 2.5mm-5mm. This embodiment offers three sizes for different age groups: adults: 4mm, 4.25mm, or 5mm; children: 3mm or 4mm; infants: 2.5mm, 2.75mm, or 3mm.

[0015] In a preferred embodiment, the otoscope is made of polyethylene, polypropylene, polyvinyl chloride, polytetrafluoroethylene, or ABS medical plastic. This embodiment uses polypropylene.

[0016] In a preferred embodiment, the handle's external shape is formed by two interlocking arcs 2-1 and 2-2, creating a flat plate structure. The flat handle has 2-3 oval-shaped cutouts 2-3 in the middle. These cutouts reduce overall weight and save materials, thus lowering costs.

[0017] Usage process

[0018] 1. Produce disposable handle-type otoscopes and perform sealing and sterilization treatment;

[0019] 2. During the physical examination, the doctor tears open the packaging bag, takes out the handle-type otoscope, holds the handle and inserts the conical otoscope tube into the auricle of the examinee. The doctor examines the condition of the external auditory canal of the examinee through the large field of view of the external otoscope, the otoscope round hole and the internal otoscope. During the examination, the doctor can freely adjust the observation position by holding the handle to obtain the largest field of view.

[0020] Based on the principles of mechanics, the currently used otoscopes are extremely laborious for doctors to operate and are not conducive to the adjustment and control of the angle when examining the external auditory canal. If a handle-type integrated otoscope is adopted, it will make it easier for doctors to operate, and the angle control to obtain the maximum field of view during the examination will be more flexible, convenient, and conducive to the examination results.

[0021] The above detailed description of the disposable handle-type otoscope with reference to the embodiments is illustrative rather than limiting. Several embodiments can be listed according to the defined scope. Therefore, changes and modifications without departing from the overall concept of this utility model should be within the protection scope of this utility model.
