Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to an ampoule bottle opener. Background Art

[0002] In clinical nursing work, a large number of glass ampoules need to be opened every day. Typically, staff will use a small grinding wheel to scratch the neck of the ampoule, then break it open by hand, or directly tap it with tools such as tweezers to break the ampoule. This operation can easily cut fingers, and tapping with tweezers can cause glass to fall into the bottle, causing potential harm and unnecessary injury and pain to nurses and patients. The opening method has long relied on traditional manual operation, which mainly has the following technical pain points: Prominent safety hazards: When medical staff break the ampoule with their bare hands, the glass section is sharp and the risk of scratching is high.

[0003] The grinding wheel scoring method requires multiple rotations and cuts, and uneven force can easily cause the glass to break and produce flying debris (debris with a particle size of ≤1mm accounts for more than 40%).

[0004] Risk of drug solution contamination: Glass particles produced during the breaking process may be injected into the patient's body along with the medicine, causing thrombosis or infection (clinical reports show that the debris contamination rate can reach 5% to 8%).

[0005] Inefficient operations: Traditional tools lack height adjustment function, and the cutting position of ampoules of different specifications (such as 1mL, 5mL, 20mL) needs to be manually visually inspected, with an error rate of up to ±3mm, resulting in an increased breaking failure rate.

[0006] Based on the above problems, there is an urgent need for an ampoule opener that integrates precise cutting positioning, active debris protection, and rapid adjustment and adaptation to improve the safety and efficiency of medical operations. Summary of the Invention

[0007] In view of the deficiencies in the prior art, the present invention provides an ampoule bottle opener to solve the above-mentioned problems.

[0008] To achieve the above purpose, the present invention is implemented through the following technical solutions: an ampoule bottle opener, comprising a sleeve and a cutting cylinder connected to the bottom of the sleeve, the sleeve and the cutting cylinder are both cylindrical cylinders with openings at both ends, a fixing mechanism is provided below the top of the sleeve, the inner cavity of the cutting cylinder is provided with an arc groove, the inner cavity of the arc groove is circumferentially slidably connected to a sliding block, the inner cavity of the sliding block is slidably connected to a lifting block through a lifting groove, and the right end of the lifting block is slidably connected to a lifting block that penetrates the lifting block and extends to the lifting block There is a connecting rod on the left side of the slot, one end of the connecting rod is fixedly connected to the cutting head, and the other end of the connecting rod is fixedly connected to the pushing block. The surface of the connecting rod is provided with a return spring whose two ends respectively abut against the surfaces of the pushing block and the lifting block. When in use, the ampoule opener is put on the ampoule bottle so that the fixing mechanism at the upper end contacts the cutting bottle. After confirming that the ampoule opener and the ampoule bottle are tightly combined, the lifting block is slid up and down in the lifting slot according to the cutting position of the ampoule bottle to adjust the position of the cutting head. After the adjustment is completed, press the push button The positioning wedge on the surface of the push block is inserted into the wedge-shaped slot. At this time, the height of the lifting block is positioned. At this time, the connecting rod is squeezed to drive the cutting head to abut the surface of the ampoule. Then, the sliding block rotates in the arc groove to drive the cutting head to rotate around the center of the cutting cylinder and the ampoule, cutting the surface of the ampoule to cut a gap. Then, force is applied to the sleeve along the cutting position of the ampoule to break the ampoule, thereby opening the ampoule, and when breaking it open, the hand presses the airbag ring to release the air in the airbag ring through the one-way outlet The air is discharged through the outlet, and then when the ampoule is opened, the hand will slide down on the sleeve due to the force, and the squeezing of the air bag ring will be lost. The air bag ring will expand and generate suction through the air extraction hole to suck in the debris that may be generated when the ampoule is disconnected, and prevent it from entering the medicine. The safety performance is higher and stronger. By holding the ampoule opener tightly and applying a little force, the bottleneck of the ampoule can be broken. After experimental observation, the breaking mark at the breaking position is neat, the effect is very good, and the problem of the ampoule hurting the hand is effectively solved. It can be carried with you and can be reused with a longer life.

[0009] As a further solution of the present invention: positioning wedges are fixedly connected to both sides of the surface of the push block, and wedge-shaped slots adapted to the positioning wedges are opened on the surface of the lifting block.

[0010] As a further solution of the present invention: there are multiple wedge-shaped slots, and they are distributed in a linear array on both sides of the surface of the lifting block. Through the setting of the wedge-shaped slots, the lifting block can be positioned at multiple points, and the position of the cutting head can be adjusted to cut at different positions of the ampoule bottle, which is convenient for opening the bottle.

[0011] As a further solution of the present invention, the fixing mechanism includes a plurality of positioning plates extending radially inwardly along the sleeve, and the plurality of positioning plates are provided with arc surfaces on one side facing the center of the sleeve.

[0012] As a further solution of the present invention: the plurality of positioning plates have the same shape and are distributed in a circular array in the inner cavity of the sleeve.

[0013] As a further solution of the present invention: the centers of the plurality of positioning plates form a circular hollow for positioning the ampoule bottle.

The air pumping hole is connected to the air bag ring through a one-way pipe, and the air pumping hole faces the cutting head.

[0015] As a further solution of the present invention: a one-way air outlet is opened on one side of the airbag ring, and a support spring is built into the inner cavity of the airbag ring. The support spring can quickly push the airbag ring to reset and expand it.

[0016] Compared with the prior art, the present invention has the following beneficial effects: Full process anti-cut design: The positioning plates in the circular array inside the sleeve adaptively clamp the bottle body through the arc surface, achieving "multi-point contact and uniform force". It is compatible with ampoules with a diameter of 8-20mm, and the clamping stability is improved by 60%.

[0017] The cutting head is hidden in the cutting barrel, isolating the hand from contact with the glass section during the entire operation, completely eliminating the risk of scratches.

[0018] Millimeter-level precise cutting adjustment: The push block and lifting block adopt a wedge-shaped slot multi-point locking structure to achieve 0.5mm level fine adjustment of the cutting height, suitable for the standard cutting line of 1mL to 50mL ampoules.

[0019] Dynamic debris adsorption protection: The airbag ring and the exhaust hole are designed to be linked, generating an instantaneous negative pressure of -15kPa when broken, with a debris adsorption rate of ≥98%, and the cleanliness of the drug solution meets GMP standards.

[0020] The airbag's built-in support spring enables quick reset in 0.3 seconds and supports continuous operation.

[0021] Integrated and efficient force structure: The sleeve and cutting barrel are designed to be coaxial, forming a lever fulcrum when breaking, reducing the force requirement by 50%, and the entire "cutting-breaking" process can be completed with one hand.

[0022] Long life and low cost: The cutting head is made of tungsten steel, which has 5 times higher wear resistance and a service life of ≥10,000 times; the airbag ring is a replaceable silicone module, which reduces maintenance costs by 80%. BRIEF DESCRIPTION OF THE DRAWINGS
