Problems solved by technology

[0002] At present, ophthalmic silicone oil injection and suction mainly rely on the injection and suction of major manufacturers. Taking Bausch & Lomb PC as an example, a machine costs more than 1 million, and there will also be consumption of consumables.
Therefore, it is necessary to design a hand-held intraocular silicone oil injection and suction device with a simple structure, so as to solve the problem that the injection and suction of silicone oil can be completed without the machine

Embodiment 1

[0044] refer to Figure 1 to Figure 5 , an ophthalmic silicone oil injection and suction system, mainly includes the following parts: the tube 1 as the main body of suction and washing, and the tube 1 can choose a syringe tube; the supporting part 11 for placing the tube 1, and the supporting part 11 is the overall support of the device ; the clamping assembly 2 for fixing the tube 1 arranged on the supporting member 11, the clamping assembly 2 can be used to realize the firm fixing of the tube 1; A sealing ring 13 is arranged on the outside; the miniature push rod 14 fixed on the supporting member 11 can achieve the purpose of driving the piston 12 to slide under the action of the micro push rod 14; it is used to connect the output of the piston 12 and the miniature push rod 14 The shaft end is connected with a fixed connecting assembly 3; the placing and gathering assembly 4 arranged on the supporting member 11; the anti-bruising assembly 5 arranged at the suction port of th...

Embodiment 2

[0054] The difference from Example 1 is that the inner wall of the tube 1 is coated with an antifouling coating, wherein the preparation process of the antifouling coating is as follows:

[0055] S1. Take the following ingredients by weight: 34 parts of methyl trimethoxy silicon epoxy, 28 parts of polyurethane resin, 45 parts of acrylate, 14 parts of citric acid, 15 parts of polycarbonate, 8 parts of isopropanol, and 10 parts of acrylamide , 5 parts of methacrylate, 14 parts of polyethylene glycol, 10 parts of stannous octoate, 10 parts of dibutyltin dilaurate;

[0056] S2. Prepare the intermediate coating body: add methyltrimethoxysilane epoxy, polyurethane resin, acrylate, citric acid, and polycarbonate into a reaction kettle at 115° C. for 30 minutes to obtain an intermediate coating body;

[0057] S3. Preparation of paint: Pour the intermediate paint body into the mixer, add isopropanol, acrylamide, methacrylate, polyethylene glycol, stannous octoate, dibutyltin dilaurate ...

Embodiment 3

[0060] The difference from Example 2 is the preparation of antifouling coating, wherein the preparation process of antifouling coating is as follows:

[0061] S1. Take the following ingredients by weight: 45 parts of methyl trimethoxy silicon epoxy, 28 parts of polyurethane resin, 38 parts of acrylate, 12 parts of citric acid, 22 parts of polycarbonate, 8 parts of isopropanol, and 10 parts of acrylamide , 5 parts of methacrylate, 14 parts of polyethylene glycol, 10 parts of stannous octoate, 15 parts of dibutyltin dilaurate;

[0062] S2. Preparation of intermediate coating body: adding methyltrimethoxysilane epoxy, polyurethane resin, acrylate, citric acid, and polycarbonate into a reaction kettle at 118° C. for 30 minutes to obtain an intermediate coating body;

[0063] S3. Preparation of paint: Pour the intermediate paint body into the mixer, add isopropanol, acrylamide, methacrylate, polyethylene glycol, stannous octoate, dibutyltin dilaurate and stir to disperse at the sam...

Abstract

The invention discloses a silicone oil injection and suction system for the ophthalmology department. The key point of the technical scheme of the silicone oil injection and suction system is that the silicone oil injection and suction system comprises a pipe barrel and also comprises a bearing piece used for placing the pipe barrel, a clamping component, a piston, a miniature push rod, a connecting component, a placing and folding component, an anti-collision component and a control component, wherein the clamping component is arranged on the bearing piece and is used for fixing the pipe barrel; the piston is connected in the pipe barrel in a sliding mode, and a sealing ring is arranged outside the piston; the miniature push rod is fixed on the bearing piece; the connecting component is used for fixedly connecting the piston with the end part of the output shaft of the miniature push rod; the placing and folding component is arranged on the bearing piece; the anti-collision component is arranged at the suction and injection opening of the pipe barrel; and the control component is used for controlling silicone oil suction speed and volume. The silicone oil injection and suction system for the ophthalmology department has a simple and exquisite structure and low cost and is capable of being used for sucking and injecting silicone oil, and another mode is provided for patients who only need to carry out oil injection and oil suction.

Description

technical field [0001] The invention relates to the medical field, more specifically, it relates to an ophthalmic silicone oil injection and suction system. Background technique [0002] At present, ophthalmic silicone oil injection and aspiration mainly rely on the injection and aspiration of major manufacturers. Take Bausch & Lomb PC as an example, each machine has more than 1 million units, and there will also be consumption of consumables. Therefore, it is necessary to design a hand-held intraocular silicone oil injection and suction device with a simple structure, so as to solve the problem that the injection and suction of silicone oil can be completed without the machine. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide an ophthalmic silicone oil injection system to solve the problems raised by the background art. [0004] To achieve the above object, the present invention provides ...
