Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a fixation device for a retrobulbar needle. Background Technology

[0002] Retrobulbar needles are commonly used instruments in ophthalmology clinics for injecting medications into the eye. Their structure is characterized by sharpness, precision, and a narrow lumen. In daily use, the cleaning, drying, and sterilization of retrobulbar needles directly affect patient medication safety and infection control. However, there are currently some safety hazards associated with the handling of retrobulbar needles.

[0003] First, due to the delicate, sharp structure and narrow lumen of the retrobulbar needle, traditional cleaning machines struggle to effectively clean its interior, thus affecting subsequent drying and sterilization. Therefore, most hospitals still rely on manual cleaning, but manual operation is not only inefficient but also carries a high risk of occupational exposure. Some medical institutions even sterilize the needle directly without cleaning before clinical use, significantly increasing the risk of intraocular infection in patients.

[0004] Secondly, in the existing manual cleaning process, nurses often need to hold the needle handle with one hand and operate a high-pressure water gun or air gun with the other to rinse the needle. Because the bulb needle is light, long and sharp, and the gloves are slippery during the operation, coupled with the impact of the high-pressure water flow, the needle is very likely to slip and injure the nurse, or be damaged due to the needle falling off.

[0005] After cleaning, the needle behind the ball needs to be placed in a mesh cleaning basket for ultrasonic vibration cleaning. However, because the needle is light, it is easy to float up or even puncture the cleaning basket during the vibration process due to the buoyancy of the water. When the cleaning basket is removed after the vibration, the operating nurse is also easy to be pricked by the exposed needle tip.

[0006] After ultrasonic cleaning, multiple retrobulbar needles are often left piled up together. Nurses need to manually sort and straighten them one by one before they can be dried. Improper placement of the retrobulbar needles will not only affect the drying effect but also increase the risk of needle pricks for nurses in subsequent sterilization processes.

[0007] During sterilization preparation, nurses must manually insert each postbulbar needle into gauze for fixation before placing it in a plastic bag for sterilization. However, this process presents at least the following problems: firstly, nurses are prone to needle pricks during the procedure; secondly, lint from the gauze may enter the needle lumen, contaminating the postbulbar needle and affecting its sharpness. Furthermore, after sterilization, the postbulbar needle may slip out of the gauze and puncture the plastic bag during transport to the clinical department. If not detected promptly, this could result in needle pricks for nurses and increase the risk of infection for patients.

[0008] In summary, the cleaning, drying, and sterilization processes of retrobulbar needles are highly dependent on manual operation. This not only increases the risk of needlestick injury to the operator but also makes it difficult to meet the growing clinical needs due to the low efficiency of manual operation. Furthermore, the traditional method of securing retrobulbar needles with gauze may cause them to slip and puncture the paper-plastic bag during transport. If not detected in time, this poses a risk of needlestick injury to the operator and infection to the patient.

[0009] Therefore, there is an urgent need for a device to fix the needle behind the bulb, which can effectively fix the needle during cleaning, drying and sterilization, reduce the risk of needlestick injury to the operator, improve work efficiency and reduce the risk of infection to the patient.

[0037] Currently, ophthalmological clinics use a large number of retrobulbar needles. During manual cleaning, nurses frequently handle sharp needles, greatly increasing the risk of needlestick injuries. To avoid accidental injuries, nurses must exercise extreme caution, which significantly reduces cleaning efficiency. In the packaging stage, needles are usually secured by inserting them into gauze, but lint from the gauze can easily enter the needle lumen, contaminating the syringe and affecting the needle's sharpness. Furthermore, during sterilization and transport, the needle may puncture the packaging, posing a risk of needlestick injury to operators and potential infection to patients.

[0038] Therefore, please refer to the appendix. Figures 1 to 3 As shown, one embodiment of this utility model provides a device for fixing a retrobulbar needle. This device is reusable, suitable for ultrasonic cleaning, and capable of withstanding high-pressure sterilization; it can be recycled and reused after sterilization. By effectively fixing the needle, it can effectively reduce the incidence of needlestick injuries to operators, improve cleaning and packaging efficiency, reduce the risk of infection for patients, and enhance the safety and standardization of retrobulbar needles during cleaning, drying, and sterilization processes.

[0039] The device for fixing the needle 40 after the ball includes a frame 10, multiple needle placement cavities 20, and a needle holder 30. The bottom of the frame 10 is provided with multiple protruding snap-fit ​​parts 11. The multiple needle placement cavities 20 are detachably connected to the frame 10. Each needle placement cavity 20 has a slot 21 on its bottom outer side wall. The slot 21 cooperates with the protruding snap-fit ​​part 11 to form a detachable connection between the needle placement cavity 20 and the frame 10. The needle holder 30 is disposed inside each needle placement cavity 20 and is used to detachably clamp and fix the handle of the needle 40 after the ball.

[0040] In this embodiment, the fixation device for the post-bulb needle includes a frame 10, multiple needle placement cavities 20, and a needle clamping seat 30. The bottom of the frame 10 has multiple protruding locking portions 11. The multiple needle placement cavities 20 are detachably connected within the frame 10. Each needle placement cavity 20 has a slot 21 on its bottom outer wall, which engages with the protruding locking portions 11 to form a detachable connection between the needle placement cavity 20 and the frame 10. The needle clamping seat 30 is disposed inside each needle placement cavity 20 and is used to detachably clamp and fix the shank of the post-bulb needle 40. This design effectively fixes the post-bulb needle 40 during cleaning, drying, and sterilization processes, reducing the risk of needle stick injuries to operators. Simultaneously, it improves work efficiency and better meets the growing clinical needs. In addition, a dedicated retrobulbar needle 40 fixation device is used instead of the traditional gauze fixation method, which avoids the retrobulbar needle 40 slipping and puncturing the paper-plastic bag during transportation, thus effectively preventing the risk of needle stick injuries to operators and the risk of infection to patients.

[0041] In some optional embodiments, the frame 10 is made of, but is not limited to, polypropylene, which has good resistance to high temperature and high pressure. The dimensions of the frame 10 can be flexibly set according to usage requirements.

[0042] In some optional embodiments, the multiple needle placement cavities 20 are marked to distinguish different clinical departments. For example, the multiple needle placement cavities 20 may be distinguished by different colors.

[0043] In some optional embodiments, the bottom of the frame 10 is provided with a plurality of protruding snap-fit ​​portions 11 at equal intervals. For example, the bottom of the frame 10 is provided with ten protruding snap-fit ​​portions 11 at equal intervals, each protruding snap-fit ​​portion 11 corresponding to a needle placement cavity 20, thus providing ten needle placement cavities 20. Each needle placement cavity 20 can hold one post-ball needle 40, allowing the frame 10, the ten needle placement cavities 20, and the ten post-ball needles 40 to be treated as a group for overall cleaning and drying, improving processing efficiency.

[0044] In existing technologies, the retrobulbar needles are typically placed in a fine-mesh cleaning basket for ultrasonic cleaning. Because the retrobulbar needles are relatively light, they tend to float on the water surface during cleaning due to buoyancy, resulting in insufficient immersion and affecting the cleaning effect. According to the relevant requirements of the Central Sterile Supply Department's "Two Regulations and One Standard," instruments need to be submerged underwater during the cleaning process. Therefore, by treating the frame 10, the ten needle placement chambers 20, and the ten retrobulbar needles 40 as a single unit for ultrasonic cleaning, the problem of the retrobulbar needles 40 floating due to buoyancy in existing technologies is avoided. This ensures that the retrobulbar needles 40 are fully immersed during the cleaning process, improving the cleaning effect and efficiency.

[0045] After cleaning, operators can directly remove the frame 10, ten needle placement chambers 20, and ten postbulbar needles 40 from the ultrasonic oscillator without disassembly. Next, operators rinse with running water to ensure complete removal of any residual cleaning solution. Then, operators use an air gun to dry the area and place the entire assembly of frame 10, ten needle placement chambers 20, and ten postbulbar needles 40 into a drying oven for drying. After drying, operators in the packaging area disassemble each of the ten needle placement chambers 20 from frame 10, and then place each needle placement chamber 20 and its corresponding postbulbar needle 40 into a paper-plastic bag for final sterilization. After use in clinical departments, the postbulbar needles 40 are discarded, and the needle placement chambers 20 are returned to the sterilization supply center for reuse.

[0046] In some optional embodiments, the distance between two adjacent protruding latches 11 is 5 mm. When the needle placement cavity 20 is detachably connected to the frame 10, a gap is left between two adjacent needle placement cavities 20, so that when the operator removes the needle placement cavity 20, he / she can easily insert his / her finger into the gap to remove the needle placement cavity 20 from the frame 10.

[0047] In some optional embodiments, the frame 10 is made of polypropylene. Snap-fit ​​interfaces 12 are provided on opposite sides of the top opening of the frame 10, and elastic buckles 22 are provided on opposite sides of the top sidewall of each needle placement cavity 20. The elastic buckles 22 cooperate with the snap-fit ​​interfaces 12 to form a detachable snap-fit ​​connection between the needle placement cavity 20 and the top of the frame 10. The connection method between the top of the frame 10 and the needle placement cavity 20 is not limited to the aforementioned cooperation of snap-fit ​​interfaces 12 and elastic buckles 22; a press-type locking device can also be used. It should be noted that the press-type locking device is a mature technical solution, and its structure and working principle have been widely used in related fields; therefore, it will not be described in detail here.

[0048] In some optional embodiments, the protruding locking portion 11 is a V-shaped guide protrusion, and the locking groove 21 is a V-shaped groove. The cooperation between the V-shaped guide protrusion and the V-shaped groove effectively reduces the shaking of the needle placement cavity 20 during ultrasonic vibration cleaning.

[0049] In some optional embodiments, a counterweight plate 13 is provided on the frame 10, and the counterweight plate 13 has perforations. The counterweight plate 13 is made of stainless steel, can be located at the bottom of the frame 10, and is detachable. The counterweight plate 13 ensures that the needle 40 behind the ball is fully immersed in water during the cleaning process. The perforations on the counterweight plate 13 effectively prevent water accumulation.

[0050] In some optional embodiments, the needle holder 30 includes two opposing elastic clamping arms 31, with anti-slip portions provided on the inner sides of the elastic clamping arms 31. The two elastic clamping arms 31 together form a U-shaped clamping space for clamping and fixing the shank of the spherical needle. The elastic clamping arms 31 are made of polypropylene, and the tension of the elastic clamping arms 31 can fix the shank of the spherical needle. The inner sides of the elastic clamping arms 31 are provided with silicone anti-slip textures to form anti-slip portions, effectively preventing the spherical needle from sliding during clamping.

[0051] In some alternative embodiments, an inclined grid plate 14 is provided at the bottom of the frame 10 below a plurality of protruding snap-fit ​​portions 11. The grid plate may be inclined at 15°. The inclined grid plate 14 helps to drain water and quickly expel water, thereby preventing water accumulation. When the needle placement cavity 20 is connected to the frame 10, the spherical needle held in the needle placement cavity 20 is in an upright state. The aperture of the grid plate is, but is not limited to, 3 mm.

[0052] In some alternative embodiments, the frame 10 and / or the needle holder 30 are made of polypropylene with 30% glass fiber added, which can withstand high temperature and high pressure sterilization at 135°C.

[0053] In some optional embodiments, the needle placement cavity 20 has a cuboid structure with at least one open side, facilitating the operator's placement and removal of the needle 40 and ensuring that water flow and hot air can fully contact the needle 40. It is worth noting that the corners of the needle placement cavity 20 are rounded, effectively preventing damage to the paper-plastic bag.

[0054] The cleaning, drying, and sterilization steps for the 40mm post-bulb needle are as follows:

[0055] Cleaning process: The rear needle 40 is clamped and fixed on the needle holder 30. The entire assembly (including the frame 10, the needle placement cavity 20, and the rear needle 40) is placed in the ultrasonic oscillator, where water flow impacts the rear needle 40. After cleaning, no manual sorting is required.

[0056] Drying process: Place the entire unit on a dedicated drying rack. The rack is used in conjunction with frame 10. Hot air flows through frame 10 for 30 minutes to complete the drying process.

[0057] Sterilization and packaging: Disassemble the needle placement chamber 20, and place the needle placement chamber 20 and the bulb needle 40 together into a paper-plastic bag for sterilization and packaging.

[0058] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
