Description

Technical Field

[0001] This utility model belongs to the field of medical auxiliary equipment technology, specifically relating to a handheld electric airway inner cannula cleaning brush. Background Technology

[0002] Tracheostomy with insertion of a metal or silicone tracheostomy cannula is a common treatment for relieving respiratory distress caused by laryngeal origin, respiratory dysfunction, or lower respiratory tract secretion retention. It is commonly used in departments such as respiratory medicine, otolaryngology-head and neck surgery, dentistry, and neurology. The tracheostomy cannula needs to be removed, cleaned, and disinfected daily. Currently used cannula brushes are mostly made of metal rods with nylon brush heads, which rely on repeated manual brushing. This makes it difficult to thoroughly remove stubborn sputum crusts inside the tracheostomy cannula and can easily damage the cannula wall. Reusing brush heads poses a risk of cross-infection, and sputum splashing during cleaning also carries an infection risk. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a handheld electric airway inner tube cleaning brush to overcome the shortcomings of the prior art.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0005] A handheld electric airway inner cannula cleaning brush is provided, comprising a disposable brush head and an electric handle that are detachably connected. The electric handle has a built-in power supply component, a vibration component, and a vibration transmission component. The top of the electric handle is provided with a first connecting seat, and the bottom of the disposable brush head is provided with a second connecting seat that is compatible with the first connecting seat. The vibration component is connected to the first connecting seat through the vibration transmission component. The handle shell of the electric handle is provided with a power switch. The disposable brush head includes a brush shaft, and brushing components are evenly arranged around the brush shaft.

[0006] As described in the handheld electric airway inner tube cleaning brush, the brushing assembly comprises, from the outside to the inside, a bristle layer, a silicone scraper layer, and a sponge layer.

[0007] As described in the handheld electric air tube cleaning brush, the front end of the brush shaft is flexible and bendable, with a bending angle of ±30°.

[0008] As described in the handheld electric air tube inner sleeve cleaning brush, the front end of the electric handle is provided with a semi-ellipsoidal transparent silicone splash guard, the concave surface of the transparent silicone splash guard faces the disposable brush head, and the inner wall of the transparent silicone splash guard is provided with a guide groove.

[0009] As described in the handheld electric air hose inner tube cleaning brush, the first connector has an upward protrusion in the middle to form a plug, the bottom center of the second connector has a cavity that matches the plug, the plug has circumferentially arranged convex ribs, and the inner wall of the cavity has grooves that match the convex ribs.

[0010] As described in the handheld electric airway inner tube cleaning brush, the grip area of ​​the electric handle is provided with anti-slip texture.

[0011] The beneficial effects of this utility model's technical solution are:

[0012] The outermost bristles of the disposable brush head can remove stubborn phlegm crusts, the middle silicone scraper adheres to the tube wall to scrape away residue, and the inner absorbent sponge wraps around the base of the brush head to absorb loose dirt. Through high-frequency vibration combined with the disposable brush head, the physical removal effect of the bristles on phlegm crusts is enhanced, while avoiding manual force operation, achieving efficient cleaning and reducing the risk of infection. It is also convenient to use and carry. Attached Figure Description

[0019] See Figure 1 As shown, the handheld electric air hose inner sleeve cleaning brush of this utility model includes a disposable brush head 1 and an electric handle 2 that are detachably connected to each other. The electric handle 2 has a built-in power supply component, a vibration component and a vibration transmission component. The top of the electric handle 2 is provided with a first connecting seat 3, and the bottom of the disposable brush head 1 is provided with a second connecting seat 4 that is compatible with the first connecting seat 3. The vibration component is connected to the first connecting seat 3 through the vibration transmission component. The handle shell of the electric handle 2 is provided with a power switch 5. The disposable brush head 1 includes a brush shaft 6, and the brushing components are evenly arranged around the brush shaft 6.

[0020] Furthermore, the brushing assembly comprises, from the outside in, a bristle layer 7, a silicone scraper layer 8, and a sponge layer 9. The outermost bristle layer is made of nylon bristles, with an implantation density of 15-20 tufts / cm². 2 It can remove stubborn phlegm crusts. The middle layer of silicone scraper is designed to adhere to the tube wall to scrape away residue, while the inner layer of absorbent sponge wraps around the base of the brush head to absorb loose dirt.

[0021] The brush shaft 6 is made of medical-grade PP plastic, with a flexible and bendable front end, and a bending angle of ±30°.

[0022] The electric handle 2 has a semi-ellipsoidal transparent silicone splash guard 10 at its front end. The concave surface of the transparent silicone splash guard 10 faces the disposable brush head 1. The inner wall of the transparent silicone splash guard 10 has a guide groove to guide the splashed liquid to the outside. The thickness of the splash guard is approximately 0.3 mm, and its diameter is approximately twice the outer diameter of the brush head. Regarding the connection method between the splash guard and the handle, it can be connected by heat fusion or other methods, which is existing technology.

[0023] Referring again to the diagram, the first connector 3 has an upward protrusion in the middle to form a plug 11. The bottom center of the second connector 4 has a cavity that matches the plug 11. The plug 11 has spaced-apart protrusions 12 around its circumference, and the inner wall of the cavity has spaced-apart grooves that match the protrusions 12. In use, the plug 11 is inserted into the cavity, and then the brush head is rotated to make the protrusions 12 engage with the grooves. To remove the brush head, the brush head is first rotated to disengage the protrusions 12 from the grooves, and then the brush head is removed.

[0024] The vibration component uses a miniature high-frequency vibration motor (5000-10000 times / minute), the power supply component is a disposable battery or a rechargeable battery (using a rechargeable battery with a corresponding charging interface on the handle is existing technology), and the vibration transmission component is a vibration shaft connected to the central shaft of the motor.

[0025] The electric handle 2 has a waterproof shell and a grip area with anti-slip texture to increase friction.

[0026] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model.
